BASE PROSPECTUS

$75,000,000

Western Asset Mortgage Opportunity Fund Inc.

Common Stock

Subscription Rights to Purchase Common Stock

The Fund. Western Asset Mortgage Opportunity Fund Inc. (the “Fund”) is a non-diversified, closed-end management investment company.

Investment Objectives. The Fund’s primary investment objective is to provide current income. As a secondary investment objective, the Fund will seek capital appreciation. There can be no assurance that the Fund will achieve its investment objectives.

Investment Strategies. The Fund seeks to achieve its investment objectives by investing primarily in a portfolio of mortgage-backed securities (“MBS”) and mortgage whole loans. Investments in mortgage-backed securities consist primarily of non-agency residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”). The Fund’s investments in mortgage whole loans under normal circumstances will not exceed 20% of its Managed Assets (as defined below).

The Fund’s shares of common stock (“Common Stock”) are listed on the New York Stock Exchange (“NYSE”) under the trading or “ticker” symbol “DMO.” The net asset value of our Common Stock at the close of business on August 20, 2024 was $12.23 per share, and the last sale price per share of our Common Stock on the NYSE on that date was $12.21.

Offering. The Fund may offer, from time to time, in one or more offerings, our Common Stock, which we also refer to as our securities, at prices and on terms to be set forth in one or more Prospectus Supplements to this Prospectus.

We may offer and sell our securities to or through underwriters, through dealers or agents that we designate from time to time, directly to purchasers, through at-the-market offerings or through a combination of these methods. An at-the-market offering is an offering where the price per share of the Fund’s common stock is determined by the market price per share of the Fund’s outstanding common stock as of the time of each take-down offering. If an offering of securities involves any underwriters, dealers or agents, then the applicable Prospectus Supplement will name the underwriters, dealers or agents and will provide information regarding any applicable purchase price, fee, commission or discount arrangements made with those underwriters, dealers or agents or the basis upon which such amount may be calculated. See “Plan of Distribution—Distribution Through Agents,” “—Distribution Through Underwriters” and “—Distribution Through Dealers.” We may not sell any of our securities through agents, underwriters or dealers without delivery of a Prospectus Supplement describing the method and terms of the offering of our securities.

Investment Manager and Subadviser. Franklin Templeton Fund Adviser, LLC (formerly known as Legg Mason Partners Fund Advisor, LLC) (“FTFA” or the “Manager”), the Fund’s investment manager, supervises the day-to-day management of the Fund’s portfolio by Western Asset Management Company, LLC (“Western Asset”) and Western Asset Management Company Limited (“Western Asset Limited”) and provides administrative and management services to the Fund.

Investing in the Fund’s securities involves certain risks, including risks that make the offering of securities speculative (See “Below Investment Grade (“High Yield” or “Junk”) Securities Risk,” “Subprime Mortgage Market Risk” and “Distressed Investments”). You could lose some or all of your investment. See “Risks ” beginning on page 50 of this Prospectus and any Prospectus Supplement.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Prospectus dated August 28, 2024.

(continued on following page)

(continued from previous page)

Western Asset, the Fund’s subadviser, is responsible for the day-to-day portfolio management of the Fund, subject to the supervision of the Fund’s Board of Directors and FTFA. As of December 31, 2023, Western Asset and its supervised affiliates total assets under management were approximately $388.9 billion.

In connection with Western Asset’s service to the Fund, Western Asset Limited provides certain subadvisory services to the Fund relating to currency transactions and investments in non-U.S. dollar denominated debt securities. FTFA, Western Asset and Western Asset Limited are wholly-owned subsidiaries of Franklin Resources, Inc., a global investment management organization operating as Franklin Templeton.

Leverage. The Fund may seek to enhance the level of its current distributions to holders of Common Stock (“Common Stockholders”) through the use of leverage. The Fund may use leverage directly at the fund level through borrowings, including loans from certain financial institutions, the use of reverse repurchase agreements and/or the issuance of debt securities (collectively, “Borrowings”), and possibly through the issuance of preferred stock (“Preferred Stock”). The Fund may use leverage through Borrowings in an aggregate amount of up to approximately 33 1/3% of the Fund’s total assets less all liabilities and indebtedness not represented by senior securities (for these purposes, “total net assets”) immediately after such Borrowings. Furthermore, the Fund may use leverage through the issuance of Preferred Stock in an aggregate amount of liquidation preference attributable to the Preferred Stock combined with the aggregate amount of any Borrowings of up to approximately 50% of the Fund’s total net assets immediately after such issuance. Currently, the Fund has no intention to issue notes or debt securities or Preferred Stock. In addition, the Fund may enter into additional reverse repurchase agreements and/or use similar investment management techniques that may provide leverage, subject to the requirements of Rule 18f-4 under the 1940 Act. Under Rule 18f-4(d), the Fund may enter into reverse repurchase agreements or similar financing transactions in reliance on the rule if the Fund either (i) complies with the asset coverage requirements of Section 18 of the 1940 Act, and combines the aggregate amount of indebtedness associated with all reverse repurchase agreements or similar financing transactions with the aggregate amount of any other senior securities representing indebtedness when calculating its asset coverage ratio; or (ii) treats all reverse repurchase agreements or similar financing transactions as derivatives transactions for all purposes under the rule.

A distribution by the Fund consisting of a return of capital should not be considered a dividend yield or total return of an investment in the Fund’s Common Stock. Common Stockholders who receive the payment of a distribution consisting of a return of capital may be under the impression that they are receiving net profits when they are not. Stockholders should not assume that the source of a distribution from the Fund is net profits. In general terms, a return of capital would involve a situation in which a Fund distribution (or a portion thereof) represents a return of a portion of a stockholder’s investment in the Fund, rather than making a distribution that is funded from the Fund’s earned income or other profits. Although return of capital distributions may not be currently taxable, such distributions would decrease the basis of a stockholder’s shares (but not below zero), and therefore, may increase a stockholder’s tax liability for capital gains upon a sale of shares, even if sold at a loss to the stockholder’s original investment.

The Fund currently uses leverage through Borrowings and as of December 31, 2023, 42% of the Fund’s gross assets were levered. See “Leverage,” “Description of Shares—Preferred Stock” and “Risks—Risks Related to the Fund—Leverage Risk.”

This Prospectus is part of a registration statement that we have filed with the Securities and Exchange Commission (the “SEC”), using the “shelf” registration process. Under the shelf registration process, we may offer, from time to time, separately or together in one or more offerings, the securities described in this Prospectus. The securities may be offered at prices and on terms described in one or more supplements to this Prospectus. This Prospectus provides you with a general description of the securities that we may offer. Each time we use this Prospectus to offer securities, we will provide a Prospectus Supplement that will contain specific information about the terms of that offering. The Prospectus Supplement may also add, update or change information contained in this Prospectus. This Prospectus, together with any Prospectus Supplement, sets forth concisely the information about us that a prospective investor ought to know before investing. You should read this Prospectus and the related Prospectus Supplement before deciding whether to invest and retain them for future reference. A Statement of Additional Information, dated August 28, 2024 (the “SAI”), containing additional information about us, has been filed with the SEC and is incorporated by reference in its entirety into this Prospectus. You may request a free copy of the SAI (the table of contents of which is on page i of this Prospectus), annual and semi-annual reports to stockholders (when available), and additional information about the Fund by calling (888) 777-0102, by writing to the Fund at 620 Eighth Avenue, 47th Floor, New York, NY 10018 or visiting the Fund’s website (http://www.franklintempleton.com/investments/options/closed-end-funds).

The information contained in, or accessed through, the Fund’s website is not part of this Prospectus. You may also obtain a copy of the SAI (and other information regarding the Fund) from the SEC’s Public Reference Room in Washington, D.C. Information relating to the Public Reference Room may be obtained by calling the SEC at (202) 551-8090. Such materials, as well as the Fund’s annual and semi-annual reports (when available) and other information regarding the Fund, are also available on the SEC’s website (http://www.sec.gov). You may also e-mail requests for these documents to publicinfo@sec.gov or make a request in writing to the SEC’s Public Reference Room, 100 F Street, N.E., Washington, D.C. 20549-0102.

As permitted by regulations adopted by the SEC, the Fund does not intend to mail paper copies of the Fund’s shareholder reports, unless you specifically request paper copies of the reports from the Fund or from your financial intermediary (such as a broker-dealer or bank). Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report. If you invest through a financial intermediary and you already elected to receive shareholder reports electronically (“e-delivery”), you will not be affected by this change and you need not take any action. If you have not already elected e-delivery, you may elect to receive shareholder reports and other communications from the Fund electronically by contacting your financial intermediary. You may elect to receive all reports in paper free of charge. If you invest through a financial intermediary, you can contact your financial intermediary to request that you receive paper copies of your shareholder reports. That election will apply to all legacy Legg Mason funds held in your account at that financial intermediary. If you are a direct shareholder with the Fund, you can call the Fund at 1-888-888-0151, or write to the Fund by regular mail at P.O. Box 505000, Louisville, KY 40233 or by overnight delivery to Computershare, 462 South 4th Street, Suite 1600, Louisville, KY 40202 to let the Fund know you wish to receive paper copies of your shareholder reports. That election will apply to all legacy Legg Mason funds held in your account held directly with the fund complex.

Shares of common stock of closed-end investment companies frequently trade at discounts to their net asset values. If our Common Stock trades at a discount to our net asset value, the risk of loss may increase for purchasers of our Common Stock, especially for those investors who expect to sell their common stock in a relatively short period after purchasing shares in this offering. See “Risks—Market Discount from Net Asset Value Risk.”

The Fund’s securities do not represent a deposit or obligation of, and are not guaranteed or endorsed by, any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other governmental agency.

It is currently anticipated that the Fund will be able to invest substantially all of the net proceeds in accordance with its investment objective and policies within three months after the completion of any offering.

MARKET AND NET ASSET VALUE INFORMATION

The Fund’s currently outstanding Common Stock is listed on the NYSE under the symbol “DMO.” Our Common Stock commenced trading on the NYSE on February 24, 2010.

Our Common Stock has traded both at a premium and at a discount in relation to the Fund’s net asset value per share. Although our Common Stock has traded at a premium to net asset value, we cannot assure that this will occur after any offering or that the Common Stock will not trade at a discount in the future. Our issuance of additional Common Stock may have an adverse effect on prices in the secondary market for our Common Stock by increasing the number of shares of Common Stock available, which may create downward pressure on the market price for our Common Stock. Shares of closed-end investment companies frequently trade at a discount to net asset value. See “Risks—Market Discount from Net Asset Value Risk.”

The following table sets forth for each of the periods indicated the range of high and low closing sale price of our Common Stock and the quarter-end sale price, each as reported on the NYSE, the net asset value per share of Common Stock and the premium or discount to net asset value per share at which our shares were trading. Net asset value is generally determined on each business day that the NYSE is open for business. See “Net Asset Value” for information as to the determination of our net asset value.

Source of market prices: NYSE

32

On August 20, 2024, the last reported sale price of our Common Stock on the NYSE was $12.21, which represented a discount of approximately 0.16% to the net asset value per share reported by us on that date.

As of March 31, 2024, we had approximately 11.4 million shares of Common Stock outstanding and we had net assets applicable to Common Stockholders of approximately $140 million.

THE FUND’S INVESTMENTS

Investment Objectives

The Fund’s primary investment objective is to provide current income. As a secondary investment objective, the Fund will seek capital appreciation. There can be no assurance the Fund will achieve its investment objectives.

This section provides additional information about the Fund’s investments and certain portfolio management techniques the Fund may use. More information about the Fund’s investments and portfolio management techniques and the associated risks is included in the SAI.

Investment Strategies

The Fund seeks to achieve its investment objectives by investing primarily in a diverse portfolio of MBS and mortgage whole loans. Investments in mortgage-backed securities consist primarily of non-agency RMBS securities and CMBS. The Fund’s investments in mortgage whole loans under normal circumstances will not exceed 20% of its Managed Assets. A mortgage whole loan is a single mortgage loan issued to a particular borrower and is not securitized. Mortgage whole loans include loans on residential properties such as one to four family dwellings and on commercial properties such as office buildings, shopping centers and other retail properties, hotels and apartment buildings. MBS represent interests in diversified pools of residential or commercial mortgage loans, and typically take the form of pass-through securities or CMOs. MBS include, but are not limited to, the following: non-agency RMBS; CMBS; U.S. agency mortgage-backed pass-through securities issued by Ginnie Mae, Fannie Mae, Freddie Mac, and other federal agencies, or issues guaranteed by them; delegated underwriting and servicing bonds, including pools of multi-family housing loans issued by Fannie Mae and Freddie Mac; CMOs, including IO, PO and other mortgage securities backed by U.S. agency or non-agency pass-through securities; mortgage-related ABS, such as HEQ securities; MBS credit default swaps (including on the CMBX, TRX and ABX indices) and other derivative instruments related to MBS; inverse floating rate securities, which are derivative interests in MBS; non-dollar RMBS; and repurchase agreements supported by agency MBS; and junior and equity tranches of MBS. The Fund may invest in MBS of any type and of any credit quality, without limitation.

Under normal circumstances, the Fund will invest at least 80% of its Managed Assets in MBS and mortgage whole loans. Derivatives counted towards the Fund’s 80% policy are valued based on market value. The Fund also may invest up to 20% of its Managed Assets in other permitted investments, including cash and cash equivalents; Treasury securities; non-mortgage related ABS backed by various asset classes including, but not limited to, small balance commercial mortgages, aircrafts, automobiles, credit cards, equipment, manufactured housing, franchises, recreational vehicles and student loans; and investment grade and below investment grade (i.e., “high yield” or “junk”) fixed income securities including bonds, debentures, notes, commercial paper and other similar types of debt instruments including hybrid securities.

The Fund may invest a substantial portion of its assets in MBS that were originally rated AAA, but subsequently have been downgraded to below investment grade and MBS that were at issuance or are currently below investment grade or not-rated.

The Fund may invest in derivative instruments, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit linked notes, credit default swaps and other swap agreements for investment, hedging and risk management purposes; provided that the Fund’s use of derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its Managed Assets. With respect to this limitation, the Fund may net derivatives with opposite exposure to the same underlying instrument.

Notwithstanding the foregoing, the Fund may invest without limitation in Treasury futures, Eurodollar futures, interest rate swaps, swaptions or similar instruments and combinations thereof. To the extent that the security or index underlying the derivative or synthetic instrument is or is composed of MBS, the Fund will include such derivative and synthetic instruments for the purposes of the Fund’s policy to invest at least 80% of

34

its Managed Assets in MBS and mortgage whole loans. The Fund may sell certain equities or fixed income securities short including, but not limited to, Treasury securities, for investing or hedging purposes.

The Fund may invest in debt investments of any maturity and duration. The Fund will invest a substantial portion of its assets in MBS that were originally rated AAA, but subsequently have been downgraded to below investment grade. The Fund is not limited in its ability to invest in below investment grade or illiquid securities. Below investment grade fixed income securities are rated below “BBB-” by S&P or Fitch, below “Baa3” by Moody’s or comparably rated by another NRSRO or, if unrated, determined by Western Asset to be of comparable quality. Below investment grade fixed income securities are commonly referred to as “high yield” or “junk” securities and are regarded as having predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. In the event that a security receives different ratings from different NRSROs, the Fund will treat the security as being rated in the highest rating category received from an NRSRO. “Illiquid securities” are securities which cannot be sold within seven days in the ordinary course of business at approximately the value at which the Fund has valued the securities.

Credit Ratings and Unrated Securities

Rating agencies are private services that provide ratings of the credit quality of debt obligations, including convertible securities. Appendix A to the SAI describes the various ratings assigned to debt obligations by S&P, Moody’s and Fitch. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risks or the liquidity of securities. Rating agencies may fail to make timely changes in credit ratings and an issuer’s current financial condition may be better or worse than a rating indicates. To the extent that the issuer of a security pays a rating agency for the analysis of its security, an inherent conflict of interest may exist that could affect the reliability of the rating. S&P, Moody’s and Fitch monitor and evaluate the ratings assigned to securities on an ongoing basis. The ratings of a debt security may change over time. As a result, debt instruments held by the Fund could receive a higher rating or a lower rating during the period in which they are held. The Fund will not necessarily sell a security when its rating is reduced below its rating at the time of purchase.

Western Asset does not rely solely on credit ratings, and develops its own analysis of issuer credit quality. The Fund may purchase unrated securities if Western Asset determines that the securities are of comparable quality to rated securities that the Fund may purchase. Unrated securities may be less liquid than comparable rated securities and involve the risk that Western Asset may not accurately evaluate the security’s comparative credit rating. Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher-quality debt obligations. To the extent that the Fund invests in high yield and/or unrated securities, the Fund’s success in achieving its investment objectives may depend more heavily on Western Asset’s creditworthiness analysis than if the Fund invested exclusively in higher-quality and rated securities.

Derivatives Risk Management

The Fund may utilize a variety of derivative instruments for investment or risk management purposes, such as options, futures contracts, swap agreements and credit default swaps. Generally derivatives are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index, and may relate to individual debt or equity instruments, interest rates, currencies or currency exchange rates and related indexes. Effective August 19, 2022, the Fund began operating under Rule 18f-4 under the 1940 Act which, among other things, governs the use of derivative investments and certain financing transactions (e.g., reverse repurchase agreements) by registered investment companies. Among other things, Rule 18f-4 requires funds that invest in derivative instruments beyond a specified limited amount to apply a VaR based limit to their use of certain derivative instruments and financing transactions and to adopt and implement a derivatives risk management program. Compliance with Rule 18f-4 by the Fund could, among other things, make derivatives more costly, limit their availability or utility, or otherwise adversely affect their performance. Rule 18f-4 may limit the Fund’s ability to use derivatives as part of its investment strategy.

35

Selection of Investments

Western Asset employs an actively managed investment approach which utilizes the expertise of its large and experienced team of credit analysts, risk analysts and portfolio managers. Western Asset believes that the ability to integrate superior fundamental credit research with relative value analysis will drive performance in the Fund’s MBS portfolio. A team of investment professionals at Western Asset has daily responsibility for the management of the portfolio and for the implementation of the investment process.

Western Asset has extensive experience analyzing the relative value of securities within various sectors of the mortgage markets, including undervalued distressed assets. Western Asset intends to seek to maximize returns on the Fund’s investments in distressed assets by evaluating market opportunities based on the condition of the various sectors of the mortgage markets, the relative value of the specific asset within such markets and an internal risk/return analysis. In making investment decisions on behalf of the Fund, Western Asset will incorporate its views on the economic environment and the outlook for the mortgage markets, including relative valuation, supply and demand trends, the level of interest rates, the shape of the yield curve, prepayment rates, financing and liquidity, commercial and residential real estate prices, delinquencies, default rates, recovery of various segments of the economy and vintage of collateral.

Percentage Limitations

Percentage limitations described in this prospectus are as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of credit rating downgrades or market value fluctuations of the Fund’s portfolio securities.

Portfolio Composition

The Fund’s portfolio is composed principally of the following investments. Additional information regarding the Fund’s investment policies, restrictions and portfolio investments is contained in the SAI.

MBS

MBS are structured debt obligations collateralized by pools of commercial or residential mortgages. Pools of mortgage loans and mortgage-related loans, such as mezzanine loans, are assembled into pools of assets that secure or back securities sold to investors by various governmental, government-related and private organizations. MBS in which the Fund may invest include those with fixed, floating or variable interest rates, those with interest rates that change based on a specified index of interest rates and those with interest rates that change inversely to changes in interest rates, as well as those that do not bear interest. The Fund may invest in RMBS and CMBS, including residual interests, issued by private issuers, including subordinated mortgage-related securities. The Fund may invest in subprime mortgages or MBS that are backed by subprime mortgages. Other mortgage-related securities in which the Fund may invest are described below.

Non-Agency RMBS

Non-agency RMBS are residential MBS that are collateralized by pools of mortgage loans assembled for sale to investors by non-government entities such as commercial banks, savings and loan associations and specialty finance companies. Non-agency RMBS are not issued or guaranteed by a U.S. government agency or federally chartered corporation. Non-agency RMBS also include CRT securities, which are securities issued by Fannie Mae, but unlike other securities issued by those agencies, they are not guaranteed and are subject to credit risk. Like agency RMBS, non-agency RMBS represent interests in pools of mortgage loans secured by residential real property.

The mortgage loan collateral for non-agency RMBS consists of residential mortgage loans that do not generally conform to underwriting guidelines issued by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. government, such as Ginnie Mae, due to certain factors, including

36

mortgage balances in excess of agency underwriting guidelines, borrower characteristics, loan characteristics and level of documentation, and therefore are not issued or guaranteed by an agency. Senior RMBS typically are rated by at least one NRSRO, such as Moody’s, S&P, or Fitch, and are or were at the time of issuance normally AAA-rated by at least one of these rating agencies, although such ratings may have been subsequently downgraded.

The non-agency and agency RMBS acquired by the Fund could be secured by fixed-rate mortgages (“FRMs”), adjustable rate mortgages (“ARMs”), or hybrid adjustable-rate mortgages (“hybrid ARMs”). FRMs have interest rates that are fixed for the term of the loan and do not adjust. The interest rates on ARMs generally adjust annually (although some may adjust more frequently) to an increment over a specified interest rate index. Hybrid ARMs have interest rates that are fixed for a specified period of time (typically three, five, seven or ten years) and, thereafter, adjust to an increment over a specified interest rate index. ARMs and hybrid ARMs generally have periodic and lifetime constraints on how much the loan interest rate can change on any predetermined interest rate reset date. Relative value analysis, including consideration of current market conditions, will determine the Fund’s allocation to FRMs, ARMs and hybrid ARMs.

The Fund’s allocation of non-agency RMBS collateralized by FRMs, ARMs or hybrid ARMs will depend on various factors including, but not limited to, relative value, expected future prepayment trends, home price appreciation trends, supply and demand, availability of financing, expected future interest rate volatility and the overall state of the non-agency RMBS secondary market. Borrowers of the underlying loans that secure the non-agency RMBS assets which the Fund may purchase can be divided into prime, Alternative-A (“Alt-A”) and subprime borrowers based on their credit rating.

CMBS

CMBS are securities backed by obligations (including certificates of participation in obligations) that are principally secured by commercial mortgages on real property or interests therein having a multifamily or commercial use, such as regional malls, other retail space, office buildings, industrial or warehouse properties, hotels, apartments, nursing homes and senior living facilities. The Fund’s emphasis will be on securities that when originally issued were rated in the highest rating category by one or more of the NRSROs, however, the Fund has not established a minimum current rating requirement.

CMBS are typically issued in multiple tranches whereby the more senior classes are entitled to priority distributions from the trust’s income to make specified interest and principal payments on such tranches. Losses and other shortfalls from expected amounts to be received on the mortgage pool are borne by the most subordinate classes, which receive principal payments only after the more senior classes have received all principal payments to which they are entitled. The credit quality of CMBS depends on the credit quality of the underlying mortgage loans, which is a function of factors such as the principal amount of loans relative to the value of the related properties; the cash flow produced by the property; the mortgage loan terms, such as amortization; market assessment and geographic location; construction quality of the property; and the creditworthiness of the borrowers.

Agency RMBS

Agency RMBS are residential MBS for which a U.S. government agency such as Ginnie Mae, or a federally chartered corporation such as Fannie Mae or Freddie Mac guarantees payments of principal and interest on the securities. Although the U.S. government guarantees principal and interest payments on securities issued by the U.S. government and some of its agencies, such as securities issued by Ginnie Mae, this guarantee does not apply to losses resulting from declines in the market value of these securities. Some agency RMBS that the Fund may hold are not guaranteed or backed by the full faith and credit of the U.S. government, such as those issued by Fannie Mae and Freddie Mac. Although the U.S. government has provided financial support to Fannie Mae and Freddie Mac, there can be no assurance that it will support these or other government-sponsored enterprises in the future.

37

Agency RMBS differ from other forms of traditional debt securities, which normally provide for periodic payments of interest in fixed amounts with principal payments at maturity or on specified call dates. Instead, agency RMBS provide for monthly payments, which consist of both principal and interest. In effect, these payments are a “pass-through” of scheduled and prepaid principal payments and the monthly interest made by the individual borrowers on the mortgage loans, net of any fees paid to the issuers, servicers or guarantors of the securities. The principal may be prepaid at any time due to prepayments on the underlying mortgage loans or other assets. These differences can result in significantly greater price and yield volatility than is the case with traditional fixed-income securities.

The Fund’s allocation of agency RMBS collateralized by FRMs, ARMs or hybrid ARMs will depend on various factors including, but not limited to, relative value, expected future prepayment trends, supply and demand, costs of hedging, costs of financing, expected future interest rate volatility and the overall shape of the Treasury and interest rate swap yield curves. Western Asset intends to take these factors into account when making investments. In the future, the Fund’s residential portfolio may extend to debentures that are issued and guaranteed by Freddie Mac or Fannie Mae or MBS the collateral of which is guaranteed by Ginnie Mae, Freddie Mac, Fannie Mae or another federally chartered corporation.

Stripped Mortgage-Backed Securities

The Fund also may invest in stripped mortgage-backed securities (“Stripped MBS”). Stripped MBS are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each with a specified percentage of the underlying security’s principal or interest payments. Mortgage securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security, known as an “IO,” and all of the principal is distributed to holders of another type of security known as a “PO.” Strips can be created in a pass-through structure or as tranches of a CMO. The yields to maturity on IOs and POs are very sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IOs. Conversely, if the underlying mortgage assets experience less than anticipated prepayments of principal, the yield on POs could be materially and adversely affected.

Mortgage Whole Loans

A mortgage whole loan is a single mortgage loan issued to a particular borrower and is not securitized. Mortgage whole loans include loans on residential properties such as one to four family dwellings and on commercial properties such as office buildings, shopping centers and other retail properties, hotels and apartment buildings. By investing in mortgage whole loans, the Fund acquires the entire beneficial interest in a single residential or commercial mortgage that has not been securitized, rather than fractional portions of or participations in such loans.

When the Fund invests directly or indirectly in whole loans, it typically purchases all rights, title and interest in the loans pursuant to a loan purchase agreement directly from the platform or its affiliate. The platform or a third-party servicer typically continues to service the loans, collecting payments and distributing them to investors, less any servicing fees assessed against the Fund, and the servicing entity typically will make all decisions regarding acceleration or enforcement of the loans following any default by a borrower. Where a platform or its affiliate acts as the loan servicer, there is typically a backup servicer in place in case that platform or affiliate ceases or fails to perform these servicing functions. The Fund, as an investor in a whole loan, would be entitled to receive payment only from the borrower and/or any guarantor, and would not be able to recover any deficiency from the platform, except under very narrow circumstances, which may include fraud by the borrower in some cases. As described above, the whole loans in which the Fund may invest may be secured or unsecured.

38

Inverse Floating Rate Securities and Tender Option Bonds

The Fund may invest in inverse floating rate securities (sometimes referred to as “inverse floaters”), which are derivative interests in MBS and participate in the creation of tender option bonds. Although volatile, these residual interests typically offer the potential for yields exceeding the yields available on fixed-rate MBS with comparable credit quality, coupon, call provisions and maturity.

Generally, inverse floating rate securities represent beneficial interests in a special purpose trust, which is sometimes referred to as a tender option bond trust, formed by a third party sponsor for the purpose of holding MBS. The special purpose trust typically sells two classes of beneficial interests or securities: short-term floating rate MBS (sometimes referred to as short-term floaters or tender option bonds), which are sold to third party investors, and inverse floating rate MBS, which the Fund would purchase. The short-term floating rate securities have first priority on the cash flow from the MBS held by the special purpose trust. For its inverse floating rate investment, the Fund receives the residual cash flow from the special purpose trust. If the Fund is the initial seller of the MBS to the special purpose trust, it receives the proceeds from the sale of the floating rate interests in the special purpose trust, less certain transaction costs. These proceeds generally would be used by the Fund to purchase additional MBS or other investments permitted by the Fund’s investment policies. If the Fund ever purchases all or a portion of the short-term floating rate securities sold by the special purpose trust, it may surrender those short-term floating rate securities together with a proportionate amount of residual interests to the trustee of the special purpose trust in exchange for a proportionate amount of the MBS owned by the special purpose trust. In addition, all voting rights and decisions to be made with respect to any other rights relating to the MBS held in the special purpose trust are passed through to the Fund, as the holder of the residual interests. The Fund will recognize taxable capital gains (or losses) upon any sale of MBS to the special purpose trust.

Typically, a third party, such as a bank, broker dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees. The holder of the short-term floater effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, an institution will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer or certain events that indicate the issuer of the bonds may be entering bankruptcy. If the liquidity provider acquires the floating rate interests upon the occurrence of an event described above, the liquidity provider generally will be entitled to an in-kind distribution of the MBS owned by the special purpose trust or to cause the special purpose trust to sell the bonds and distribute the proceeds to the liquidity provider. The liquidity provider generally will enter into an agreement with the Fund that will require the Fund to make a payment to the liquidity provider in an amount equal to any loss suffered by the liquidity provider in connection with the foregoing transactions. Under these agreements, the Fund’s potential exposure to losses related to or on inverse floaters may increase beyond the value of the Fund’s inverse floater investments as the Fund may potentially be liable to fulfill all amounts owed to holders of the floating rate certificates.

In order to cover any potential obligation of the Fund to the liquidity provider pursuant to this agreement, the Fund may designate on its books and records liquid instruments having a value not less than the amount, if any, by which the original purchase price of the floating rate interests issued by the related special purpose trust exceeds the market value of the MBS owned by the special purpose trust.

Although regular inverse floating rate securities are derivative securities with economic leverage embedded in them, they will not constitute senior securities of the Fund (and will not be subject to the Fund’s limitations on borrowings), because the Fund has no ongoing obligations to any party in connection with its ownership of such interests. With respect to highly leveraged inverse floating rate securities, if the Fund establishes and maintains a segregated account to cover any potential obligation to the liquidity provider, the Fund’s obligation to the liquidity provider pursuant to the agreement will not be considered a borrowing by the Fund; however, under circumstances in which the Fund does not establish and maintain such a segregated account, such obligation will be considered a borrowing for the purpose of the Fund’s limitation on borrowings.

39

ABS

ABS are securities that are primarily serviced by the cash flows of a discrete pool of receivables or other financial assets, either fixed or revolving, that by their terms convert into cash within a finite time period. Asset-backed securitization is a financing technique in which financial assets, in many cases themselves less liquid, are pooled and converted into instruments that may be offered and sold in the capital markets. In a basic securitization structure, an entity, often a financial institution, originates or otherwise acquires a pool of financial assets, either directly or through an affiliate. It then sells the financial assets, again either directly or through an affiliate, to a specially created investment vehicle that issues securities “backed” or supported by those financial assets, which securities are ABS. Payment on the ABS depends primarily on the cash flows generated by the assets in the underlying pool and other rights designed to assure timely payment, such as liquidity facilities, guarantees or other features generally known as credit enhancements. While residential mortgages were the first financial assets to be securitized in the form of MBS, non-mortgage related securitizations have grown to include many other types of financial assets, including, but not limited to, small balance commercial mortgages, aircrafts, automobiles, credit cards, equipment, manufactured housing, franchises, recreational vehicles and student loans.

Below Investment Grade (“High Yield” or “Junk”) Securities

A significant portion of the Fund’s portfolio may consist of below investment grade securities (commonly referred to as “high yield” or “junk” securities). The issuers of high yield securities may be highly leveraged and have difficulty servicing their debt, especially during prolonged economic recessions or periods of rising interest rates. The prices of lower quality securities are volatile and may go down due to market perceptions of deteriorating issuer creditworthiness or economic conditions. Lower quality securities may become illiquid and hard to value in down markets. Securities rated below investment grade are considered speculative and, compared to investment grade securities, tend to have more volatile prices, increased price sensitivity to changing interest rates and to adverse economic and business developments, greater risk of loss due to default or declining credit quality, greater likelihood that adverse economic or issuer specific events will make the issuer unable to make interest and/or principal payments and greater susceptibility to negative market sentiments leading to depressed prices and decrease in liquidity. See “Risks—Risks Related to the Fund—Below Investment Grade (“High Yield” or “Junk”) Securities Risk.”

If a fixed income security is considered investment grade at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. With respect to securities that are downgraded, Western Asset will consider what action, including the sale of the security, is in the best interests of the Fund and its stockholders.

Corporate Bonds

The Fund may invest in a wide variety of bonds of varying maturities issued by U.S. and foreign corporations and other business entities. Bonds are fixed or variable rate debt obligations, including bills, notes, debentures, money market instruments and similar instruments and securities. Corporate bonds are generally used by corporations to borrow money from investors. The issuer pays the investor a fixed or variable rate of interest and normally must repay the amount borrowed on or before maturity. Certain bonds are “perpetual” in that they have no maturity date. The investment return of corporate bonds reflects interest on the security and changes in the market value of the security. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates, and may also be affected by the credit rating of the corporation, the corporation’s performance, perceptions of the corporation in the marketplace and general market liquidity. The value of the intermediate-and longer-term corporate bonds in which the Fund generally will invest normally fluctuates more in response to changes in interest rates than does the value of shorter-term corporate bonds. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by a bond.

40

Government Debt Securities

The Fund may invest in government debt securities, including those of emerging market issuers or of other non-U.S. issuers. Government debt securities include: debt securities issued or guaranteed by governments, governmental agencies or instrumentalities and political subdivisions; debt securities issued by government owned, controlled or sponsored entities; interests in entities organized and operated for the purpose of restructuring the investment characteristics of instruments issued by the above-noted issuers; or debt securities issued by supranational entities such as the World Bank or the European Union. Emerging market debt securities generally are rated in the lower rating categories by recognized credit rating agencies or are unrated and considered to be of comparable quality to lower rated debt securities. A non-U.S. issuer of debt or the non-U.S. governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. Some of these risks do not apply to issuers in larger, more developed countries. These risks are more pronounced in investments in issuers in emerging markets or if the Fund invests significantly in one country.

Derivatives

Generally, derivatives are financial contracts whose value depends upon, or are derived from, the value of an underlying asset, reference rate or index, and may relate to individual debt or equity instruments, interest rates, currencies or currency exchange rates and related indexes. The Fund may invest in derivative instruments, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit linked notes, credit default swaps and other swap agreements for investment, hedging and risk management purposes; provided that the Fund’s exposure to derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its Managed Assets. With respect to this limitation, the Fund may net derivatives with opposite exposure to the same underlying instrument. Notwithstanding the foregoing, the Fund may invest without limitation in Treasury futures, Eurodollar futures, interest rate swaps, swaptions or similar instruments and combinations thereof. To the extent that the security or index underlying the derivative or synthetic instrument is or is composed of MBS, the Fund will include such derivative and synthetic instruments for the purposes of the Fund’s policy to invest at least 80% of its Managed Assets in MBS and mortgage whole loans. The Fund may sell certain equities or fixed income securities short including, but not limited to, Treasury securities, for investment and/or hedging purposes. See “Risks—Risks Related to the Fund—Derivatives Risk.” The Fund may use any or all of these techniques at any time, and the use of any particular derivative transaction will depend on market conditions. The Fund’s ability to pursue certain of these strategies may be limited by applicable regulations of the Commodity Futures Trading Commission and the federal income tax requirements applicable to regulated investment companies.

The Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investment directly in securities and other more traditional investments. In particular, the variable degree of correlation between price movements of instruments the Fund has purchased or sold and price movements in the position being hedged creates the possibility that losses on the hedge may be greater than gains in the value of the Fund’s position. In addition, certain derivative instruments and markets may not be liquid in all circumstances. As a result, in volatile markets, the Fund may not be able to close out a transaction without incurring losses substantially greater than the initial deposit. Although the contemplated use of these instruments should tend to minimize the risk of loss due to a decline in the value of the hedged position, at the same time they may tend to limit any potential gain which might result from an increase in the value of such position.

The successful use of derivative transactions by the Fund is subject to the ability of Western Asset to correctly predict movements in the direction of interest rates and other factors affecting markets for securities. These skills are different from those needed to select portfolio securities. If Western Asset’s expectations are not met, the Fund would be in a worse position than if a derivative transaction had not been pursued. For example, if the Fund hedged against the possibility of an increase in interest rates which would adversely affect the price of securities in its portfolio and the price of such securities increased instead, the Fund would lose part or all of the

41

benefit of the increased value of its securities because it would have offsetting losses in its derivatives positions. Losses due to derivative transactions will reduce net asset value of the Fund. See “Risks—Risks Related to the Fund—Derivatives Risk.”

The Fund will engage in derivative transactions only to the extent such transactions are consistent with the requirements of the Code for maintaining its qualification as a regulated investment company for federal income tax purposes. See “Certain United States Federal Income Tax Considerations.”

Credit Default Swaps

Credit default swaps are agreements between two counterparties that allow one counterparty (the “seller”) to purchase or be “long” a third party’s credit risk and the other party (the “buyer”) to sell or be “short” the credit risk. Typically, the buyer agrees to make regular fixed payments to the seller with the same frequency as the underlying reference bond. In exchange, the buyer typically has the right upon default of the underlying bond to put the bond to the seller in exchange for the bond’s par value plus interest. Credit default swaps can be used as a substitute for purchasing or selling a credit security and are sometimes preferable to actually purchasing the security. A purchaser of a credit default swap is subject to counterparty risk.

Credit default swap agreements may have as reference obligations one or more securities that are not currently held by the Fund. The protection buyer in a credit default contract is generally obligated to pay the protection seller an upfront or a periodic stream of payments over the term of the contract provided that no credit event, such as a default, on a reference obligation has occurred. These payments are based on the difference between an interest rate applicable to the relevant issuer less a benchmark interest rate for a given maturity. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. The Fund may be either the buyer or seller in the transaction.

As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its assets, the Fund would be subject to investment exposure on the notional amount of the swap. In connection with credit default swaps in which the Fund is the seller, the Fund will segregate cash or assets determined to be liquid by Western Asset in accordance with procedures established by the Board of Directors, owning positions covering its obligations or enter into offsetting positions, with a value at least equal to the full notional amount of the swap (minus any amounts owed to the Fund). Such segregation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will limit any potential leveraging of the Fund’s portfolio. To the extent assets are segregated, these instruments will not be considered “leverage” by the Fund for the purposes of the 1940 Act.

The Fund may also purchase credit default swaps for hedging or investment purposes. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. In connection with credit default swaps in which a Fund is the buyer, the Fund will segregate cash or assets determined to be liquid by Western Asset in accordance with procedures established by the Board of Directors, or enter into certain offsetting positions, with a value at least equal to the Fund’s exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty), on a marked-to-market basis.

The Fund may also enter into CDXs. A CDX index is an equally-weighted credit default swap index. This family of indexes is comprised of baskets of credit derivatives that are representative of certain market segments such as North American investment grade, high volatility investment grade, below investment grade, as well as emerging markets. Credit default swaps of individual reference entities are selected for inclusion in the indexes

42

based on rating requirements and liquidity requirements. A CDX index tranche provides access to customized risk, exposing each investor to losses at different levels of subordination. The lowest part of the capital structure is called the “equity tranche” as it has exposure to the first losses experienced in the basket. The mezzanine and senior tranches are higher in the capital structure but can also be exposed to loss in value.

Commercial Paper

Commercial paper represents short-term unsecured promissory notes issued in bearer form by corporations such as banks or bank holding companies and finance companies. The rate of return on commercial paper may be linked or indexed to the level of exchange rates between the U.S. dollar and a foreign currency or currencies.

Certificates of Deposit

Certificates of deposit are negotiable certificates that are issued against funds deposited in a commercial bank for a definite period of time and that earn a specified return and are normally negotiable. The issuer of a certificate of deposit agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Certificates of deposit purchased by the Fund may not be fully insured by the FDIC.

Fixed Time Deposits

Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation. There are generally no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits. The Fund may also hold funds on deposit with its custodian bank in an interest-bearing account for temporary purposes.

Bankers’ Acceptances

Bankers’ acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are “accepted” by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity.

Zero Coupon Securities and Payment-In-Kind Securities

The Fund may invest in zero coupon securities and payment-in-kind securities. Zero coupon securities are debt securities that pay no cash income and are sold at substantial discounts from their value at maturity. When a zero coupon security is held to maturity, its entire return, which consists of the amortization discount, comes from the difference between its purchase price and its maturity value. This difference is known at the time of purchase, so that investors holding zero coupon securities until maturity know at the time of their investment what the expected return on their investment will be, assuming full repayment of the bond. The Fund also may purchase payment-in-kind securities. Payment-in-kind securities pay all or a portion of their interest in the form of debt or equity securities rather than cash.

Zero coupon securities and payment-in-kind securities tend to be subject to greater price fluctuations in response to changes in interest rates than are ordinary interest-paying debt securities with similar maturities. The value of zero coupon securities appreciates more during periods of declining interest rates and depreciates more during periods of rising interest rates than ordinary interest-paying debt securities with similar maturities. Zero coupon securities and payment-in-kind securities may be issued by a wide variety of corporate and governmental issuers.

43

Other Investment Companies

The Fund may invest in securities of other closed-end or open-end investment companies that invest primarily in MBS or other securities and instruments of the types in which the Fund may invest directly to the extent permitted by the 1940 Act. The Fund may invest in other investment companies during periods when it has large amounts of uninvested cash, such as the period shortly after the Fund receives the proceeds of the offering of its Common Stock, during periods when there is a shortage of attractive bonds available in the market, or when Western Asset believes share prices of other investment companies offer attractive values. The Fund may invest in investment companies that are advised by Western Asset or its affiliates to the extent permitted by applicable law and/or pursuant to exemptive relief from the SEC. As a stockholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Stockholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. Western Asset will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available bond investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. As described in the sections entitled “Risks—Risks Related to the Fund—Leverage Risk,” the net asset value and market value of leveraged shares will be more volatile and the yield to stockholders will tend to fluctuate more than the yield generated by unleveraged shares. Other investment companies may have investment policies that differ from those of the Fund. In addition, to the extent the Fund invests in other investment companies, the Fund will be dependent upon the investment and research abilities of persons other than Western Asset.

Temporary Defensive Strategies

At times Western Asset may judge that conditions in the markets for MBS make pursuing the Fund’s primary investment strategy inconsistent with the best interests of its stockholders. During temporary defensive periods or in order to keep the Fund’s cash fully invested, including during the period when the net proceeds of the offering of Common Stock are being invested, the Fund may deviate from its investment policies and objectives. At such times Western Asset may, temporarily, use alternative strategies, primarily designed to reduce fluctuations in the value of the Fund’s assets. If the Fund takes a temporary defensive position, it may be unable to achieve its investment objectives.

In implementing these “defensive” strategies, the Fund may invest all or a portion of assets in non-U.S. government securities which have received the highest investment grade credit rating and U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the Treasury or by U.S. government agencies or instrumentalities; certificates of deposit issued against funds deposited in a bank or a savings and loan association; commercial paper; bankers’ acceptances; bank time deposits; shares of money market funds; repurchase agreements with respect to any of the foregoing; or any other fixed income securities that Western Asset considers consistent with this strategy. It is impossible to predict when, or for how long, the Fund will use these alternative strategies. There can be no assurance that such strategies will be successful.

Investment Practices

Certain Interest Rate Transactions

The Fund may enter into various interest rate transactions, such as interest rate swaps and the purchase or sale of interest rate caps and floors. Interest rate swaps involve the exchange by the Fund with a counterparty of their respective commitments to pay either a fixed or floating rate denominated in a particular currency. The Fund may enter into, among other things, fixed-for-floating rate swaps in the same currency, fixed-for-floating rate swaps in different currencies, floating-for-floating rate swaps in the same currency, floating-for-floating rate swaps in different currencies, or fixed-for-fixed rate swaps in different currencies. Fixed-for-floating rate swaps may involve the Fund agreeing with the swap counterparty to pay a fixed rate payment in exchange for the

44

counterparty paying the Fund a variable rate payment that is intended to approximate the Fund’s variable rate payment obligation. Alternatively, fixed-for-floating rate swaps may involve the Fund agreeing with the swap counterparty to pay a floating rate payment in exchange for the counterparty paying the Fund a fixed rate payment. The payment obligation would be based on the notional amount of the swap. The Fund may enter into these transactions to hedge the value of the Fund’s portfolio to seek to increase its return, to preserve a return or spread on a particular investment or portion of its portfolio, or for investment purposes.

The Fund may purchase an interest rate cap, which would require it to pay a premium to the cap counterparty and would entitle the Fund, to the extent that a specified variable rate index exceeds a predetermined fixed rate, to receive from the counterparty payment of the difference based on the notional amount. Alternatively, the Fund may sell an interest rate cap, which would require the cap counterparty to pay a premium to the Fund and would entitle the cap counterparty, to the extent that a specified variable rate index exceeds a predetermined fixed rate, to receive from the Fund payment of the difference based on the notional amount.

The Fund may use interest rate swaps or caps for hedging or investment purposes.

Total Return Swaps

The Fund may enter into total return swaps. In a total return swap, the Fund exchanges with another party their respective commitments to pay or receive the total return of an underlying debt or equity security and a floating local short-term interest rate. The payment obligation would be based on the notional amount of the swap. The Fund may use total return swaps for hedging or investment purposes.

Repurchase Agreements

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund’s cost plus interest within a specified time. If the party agreeing to repurchase should default, the Fund will seek to sell the securities which it holds. This could involve transaction costs or delays in addition to a loss on the securities if their value should fall below their repurchase price. Repurchase agreements maturing in more than seven days are considered to be illiquid securities.

Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements, under which the Fund will effectively pledge its assets as collateral to secure a short-term loan. Generally, the other party to the agreement makes the loan in an amount equal to a percentage of the market value of the pledged collateral. At the maturity of the reverse repurchase agreement, the Fund will be required to repay the loan and correspondingly receive back its collateral. While used as collateral, the assets continue to pay principal and interest which are for the benefit of the Fund.

When-Issued, Delayed Delivery and Forward Commitment Transactions

The Fund may purchase securities on a when-issued or delayed delivery basis. Securities purchased on a when-issued or delayed delivery basis are purchased for delivery beyond the normal settlement date at a stated price and yield. No income accrues to the purchaser of a security on a when-issued or delayed delivery basis prior to delivery. Such securities are recorded as an asset and are subject to changes in value based upon changes in the general level of interest rates. The Fund will make commitments to purchase securities on a when-issued or delayed delivery basis only with the intention of actually acquiring the securities but may sell them before the settlement date if it is deemed advisable. Purchasing a security on a when-issued or delayed delivery basis can involve a risk that the market price at the time of delivery may be lower than the agreed-upon purchase price, in which case there could be an unrealized loss at the time of delivery. If the Fund purchases securities on a

45

when-issued or delayed delivery basis, it will segregate liquid assets, own positions covering its obligations or enter into offsetting transactions. To the extent the Fund covers its commitment under such portfolio management technique, such instrument will not be considered a senior security for the purposes of the 1940 Act. See “The Fund’s Investments—Investment Strategies—Segregation and Cover Requirements.”

New Securities and Other Investment Techniques

New types of securities and other investment and hedging practices are developed from time to time. Western Asset expects, consistent with the Fund’s investment objectives and policies, to invest in such new types of securities and to engage in such new types of investment practices if Western Asset believes that these investments and investment techniques may assist the Fund in achieving its investment objectives. In addition, Western Asset may use investment techniques and instruments that are not specifically described herein.

Portfolio Turnover

The Fund does not have a formal portfolio turnover policy and does not intend to adopt one. Although the Fund generally intends to hold most of its RMBS and CMBS until maturity, it may, from time to time, sell any of its RMBS and CMBS as part of its overall management of its investment portfolio. When investments are realized, Western Asset will reinvest proceeds therefrom in the Fund’s target assets. Depending on market conditions, Western Asset will also make opportunistic dispositions of the Fund’s investments in its target assets. Frequent trading also increases transaction costs, which could detract from the Fund’s performance.

Fundamental Investment Policies

The Fund’s (i) investment objectives and (ii) the investment restrictions listed in the SAI, are considered fundamental and may not be changed without the approval of the holders of a majority of the outstanding Common Stock (or Preferred Stock, if any). A “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares outstanding are present or represented by proxy or (ii) more than 50% of the shares outstanding, whichever of (i) or (ii) is less. See “Investment Restrictions” in the SAI for a complete list of the fundamental and non-fundamental investment policies of the Fund.

46

LEVERAGE

The Fund may seek to enhance the level of its current distributions to Common Stockholders through the use of leverage.

The Fund may use leverage through Borrowings, and through the issuance of shares of Preferred Stock. The Fund may use leverage through Borrowings in an aggregate amount of up to approximately 33 ¹/₃% of the Fund’s total net assets immediately after such Borrowings. Furthermore, the Fund may use leverage through the issuance of Preferred Stock in an aggregate amount of liquidation preference attributable to the Preferred Stock combined with the aggregate amount of any Borrowings of up to approximately 50% of the Fund’s total net assets immediately after such issuance. The Fund may enter into reverse repurchase agreements and use similar investment management techniques that may provide leverage, subject to the requirements of Rule 18f-4 under the 1940 Act. Under Rule 18f-4(d), the Fund may enter into reverse repurchase agreements or similar financing transactions in reliance on the rule if the Fund either (i) complies with the asset coverage requirements of Section 18 of the 1940 Act, and combines the aggregate amount of indebtedness associated with all reverse repurchase agreements or similar financing transactions with the aggregate amount of any other senior securities representing indebtedness when calculating its asset coverage ratio; or (ii) treats all reverse repurchase agreements or similar financing transactions as derivatives transactions for all purposes under the rule. The Fund may not use leverage at all times and the amount of leverage may vary depending upon a number of factors, including FTFA’s and Western Asset’s outlook for the market and the costs that the Fund would incur as a result of such leverage.

The Fund currently uses leverage through Borrowings and as of December 31, 2023, 42% of the Fund’s gross assets were levered.

The Fund operates under Rule 18f-4 under the 1940 Act which, among other things, governs the use of derivative investments and certain financing transactions (e.g., reverse repurchase agreements) by registered investment companies. Among other things, Rule 18f-4 requires funds that invest in derivative instruments beyond a specified limited amount to apply a VaR based limit to their use of certain derivative instruments and financing transactions and to adopt and implement a derivatives risk management program. Compliance with Rule 18f-4 by the Fund could, among other things, make derivatives more costly, limit their availability or utility, or otherwise adversely affect their performance. Rule 18f-4 may limit the Fund’s ability to use derivatives as part of its investment strategy. Using derivatives also can have a leveraging effect and increase Fund volatility.

Currently, the Fund has no intention to use leverage through the issuance of notes or debt securities or Preferred Stock, but circumstances may arise such that the Fund may choose to issue Preferred Stock. Borrowings (and any Preferred Stock) will have seniority over Common Stock. Any Borrowings and Preferred Stock (if issued) will leverage your investment in Common Stock. Holders of Common Stock will bear the costs associated with any Borrowings, and if the Fund issues Preferred Stock, Common Stockholders will bear the offering costs of the Preferred Stock issuance. The Board of Directors of the Fund may authorize the use of leverage through Borrowings and Preferred Stock without the approval of the Common Stockholders.

Changes in the value of the Fund’s portfolio securities, including costs attributable to Borrowings or Preferred Stock, will be borne entirely by the holders of the Common Stock. If there is a net decrease (or increase) in the value of the Fund’s investment portfolio, the leverage will decrease (or increase) the net asset value per Common Stock to a greater extent than if the Fund were not leveraged. During periods when the Fund is using leverage through Borrowings or the issuance of Preferred Stock the fees paid to FTFA, Western Asset and Western Asset Limited for advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund’s Managed Assets, which includes the principal amount of the Borrowings and any assets attributable to the issuance of Preferred Stock. This means that FTFA, Western Asset, and Western Asset Limited may have a financial incentive to increase the Fund’s use of leverage.

47

Under the 1940 Act, the Fund generally is not permitted to issue commercial paper or notes or borrow unless immediately after the borrowing or commercial paper or note issuance the value of the Fund’s total assets less liabilities other than the principal amount represented by commercial paper, notes or borrowings is at least 300% of such principal amount. In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Stock unless, at the time of such declaration, the value of the Fund’s total assets, less liabilities other than the principal amount represented by commercial paper, notes or borrowings, is at least 300% of such principal amount after deducting the amount of such dividend or distribution. If the Fund borrows, the Fund intends, to the extent possible, to prepay all or a portion of the principal amount of any outstanding commercial paper, notes or borrowing to the extent necessary to maintain the required asset coverage. Failure to maintain certain asset coverage requirements could result in an event of default and entitle the debt holders to elect a majority of the Board of Directors.

Utilization of leverage is a speculative investment technique and involves certain risks to the holders of Common Stock. These include the possibility of higher volatility of the net asset value of the Common Stock and potentially more volatility in the market value of, and distributions on, the Common Stock. So long as the Fund is able to realize a higher net return on its investment portfolio than the then-current cost of any leverage together with other related expenses, the effect of the leverage will be to cause holders of Common Stock to realize a higher rate of return than if the Fund were not so leveraged. On the other hand, to the extent that the then-current cost of any leverage, together with other related expenses, approaches the net return on the Fund’s investment portfolio, the benefit of leverage to holders of Common Stock will be reduced, and if the then-current cost of any leverage together with related expenses were to exceed the net return on the Fund’s portfolio, the Fund’s leveraged capital structure would result in a lower rate of return to holders of Common Stock than if the Fund were not so leveraged. There can be no assurance that the Fund’s leveraging strategy will be successful.

Under the 1940 Act, the Fund is not permitted to issue Preferred Stock unless immediately after such issuance the value of the Fund’s asset coverage is at least 200% of the liquidation value of the outstanding Preferred Stock (i.e., such liquidation value may not exceed 50% of the Fund’s asset coverage less all liabilities other than borrowings).

In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Stock unless, at the time of such declaration, the value of the Fund’s asset coverage less liabilities other than borrowings satisfies the above-referenced 200% coverage requirement. If Preferred Stock is issued, the Fund intends, to the extent possible, to purchase or redeem Preferred Stock from time to time to the extent necessary in order to maintain coverage of at least 200%.

If Preferred Stock is outstanding, two of the Fund’s Directors will be elected by the holders of Preferred Stock, voting separately as a class. The remaining Directors of the Fund will be elected by holders of Common Stock and Preferred Stock voting together as a single class. In the unlikely event that the Fund fails to pay dividends on the Preferred Stock for two years, holders of Preferred Stock would be entitled to elect a majority of the Directors of the Fund. The failure to pay dividends or make distributions could result in the Fund ceasing to qualify for treatment as a regulated investment company under the Code, which could have a material adverse effect on the value of the Common Stock.

The Fund may be subject to certain restrictions imposed either by guidelines of a lender, if the Fund borrows from a lender, or by one or more rating agencies which may issue ratings for Preferred Stock or debt securities. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. It is not anticipated that these covenants or guidelines will impede FTFA, Western Asset, and Western Asset Limited from managing the Fund’s portfolio in accordance with the Fund’s investment objectives and policies. In addition to other considerations, to the extent that the Fund believes that the covenants and guidelines required by the rating agencies would impede its ability to meet its investment objectives, or if the Fund is unable to obtain its desired rating on Preferred Stock or debt securities, the Fund will not issue Preferred Stock or debt securities.

Effects of Leverage

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on Common Stock total return, assuming investment portfolio total returns (comprised of income and changes in the value of securities held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. See “Risks.”

The table further reflects the issuance of leverage representing 42.16% of the Fund’s Managed Assets, net of expenses, the Fund’s currently projected annual interest on its leverage of 7.41%.

Common Stock Total Return is composed of two elements: the Common Stock dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends or interest on its leverage) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table above assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the interest it receives on its debt security investments is entirely offset by losses in the value of those investments.

49

RISKS

The Fund is a non-diversified, closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. The Fund’s performance and the value of its investments will vary in response to changes in interest rates, inflation, the financial condition of a security’s issuer, ratings on a security and other market factors. Your securities at any point in time may be worth less than you invested, even after taking into account the reinvestment of Fund dividends and distributions. Below are the principal risks associated with an investment in the Fund.

Investment Risk and Market Risk

An investment in the Fund is subject to investment risk, including the possible loss of the entire amount that you invest. Your investment in the Common Stock represents an indirect investment in the securities owned by the Fund, most of which could be purchased directly. The value of the Fund’s portfolio securities may move up or down, sometimes rapidly and unpredictably. At any point in time, your Common Stock may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Market Price Discount from Net Asset Value Risk

The Fund’s Common Stock has traded both at a premium and at a discount to its net asset value. The last reported sale price, as of August 20, 2024 was $12.21 per share. The Fund’s net asset value per share and percentage discount to net asset value per share of its Common Stock as of August 20, 2024 were $12.23 and 0.16%, respectively. Shares of closed-end investment companies frequently trade at a discount to their net asset value. This characteristic is a risk separate and distinct from the risk that our net asset value could decrease as a result of the Fund’s investment activities and may be greater for investors expecting to sell their shares in a relatively short period following completion of any offering under this Prospectus. Although the value of the Fund’s net assets is generally considered by market participants in determining whether to purchase or sell shares, whether investors will realize gains or losses upon the sale of the Fund’s Common Stock depends upon whether the market price of the Fund’s Common Stock at the time of sale is above or below the investor’s purchase price for the Fund’s Common Stock. Because the market price of the Fund’s Common Stock is affected by factors such as net asset value, dividend or distribution levels (which are dependent, in part, on expenses), supply of and demand for the Fund’s Common Stock, stability of distributions, trading volume of the Fund’s Common Stock, general market and economic conditions, and other factors beyond our control, the Fund cannot predict whether the Common Stock will trade at, below or above net asset value or at, below or above the offering price. The Fund’s Common Stock is designed primarily for long-term investors and you should not view the Fund as a vehicle for trading purposes.

Risks Related to Investments in MBS

Investing in MBS entails various risks: credit risks, liquidity risks, interest rate risks, market risks, operations risks, structural risks, geographical concentration risks, basis risks and legal risks. Most MBS are subject to the significant credit risks inherent in the underlying collateral and to the risk that the servicer fails to perform. MBS are subject to risks associated with their structure and execution, including the process by which principal and interest payments are allocated and distributed to investors, how credit losses affect the issuing vehicle and the return to investors in such MBS, whether the collateral represents a fixed set of specific assets or accounts, whether the underlying collateral assets are revolving or closed-end, under what terms (including maturity of the MBS) any remaining balance in the accounts may revert to the issuing entity and the extent to which the entity that is the actual source of the collateral assets is obligated to provide support to the issuing vehicle or to the investors in such MBS. In addition, concentrations of MBS of a particular type, as well as

50

concentrations of MBS issued or guaranteed by affiliated obligors, serviced by the same servicer or backed by underlying collateral located in a specific geographic region, may subject the MBS to additional risk.

The risks associated with MBS include: (1) credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; (2) adverse changes in economic conditions and circumstances, which are more likely to have an adverse impact on MBS secured by loans on certain types of commercial properties than on those secured by loans on residential properties; (3) prepayment risk, which can lead to significant fluctuations in value of the MBS; (4) loss of all or part of the premium, if any, paid; and (5) decline in the market value of the security, whether resulting from changes in interest rates, prepayments on the underlying mortgage collateral or perceptions of the credit risk associated with the underlying mortgage collateral. The Fund substantially invests in non-agency RMBS and CMBS each of which are subject to certain specific risks as further described below. See “—Non-Agency RMBS Risk” and “—CMBS Risk.” Within non-agency RMBS, the fund invests in new-issue non-agency RMBS, legacy non-agency RMBS and CRT. Within non-agency CMBS, the fund invests in single asset single borrower (backed by hotel, industrial, mixed-use, multi-family, office, retail and other), conduit, CRE CLO and agency CMBS subordinate securities.

MBS represent an interest in a pool of mortgages. When market interest rates decline, more mortgages are refinanced and the securities are paid off earlier than expected. Prepayments may also occur on a scheduled basis or due to foreclosure. When market interest rates increase, the market values of MBS decline. At the same time, however, mortgage refinancings and prepayments slow, lengthening the effective maturities of these securities. As a result, the negative effect of the rate increase on the market value of MBS is usually more pronounced than it is for other types of debt securities. In addition, due to increased instability in the credit markets, the market for some MBS has experienced reduced liquidity and greater volatility with respect to the value of such securities, making it more difficult to value such securities.

Moreover, the relationship between borrower prepayments and changes in interest rates may mean some high-yielding mortgage-related and asset-backed securities have less potential for increases in value if market interest rates were to fall than conventional bonds with comparable maturities. In addition, in periods of falling interest rates, the rate of prepayments tends to increase. During such periods, the reinvestment of prepayment proceeds by the Fund will generally be at lower rates than the rates that were carried by the obligations that have been prepaid. Because of these and other reasons, mortgage-related and asset-backed security’s total return and maturity may be difficult to predict precisely. To the extent that the Fund purchases mortgage-related securities at a premium, prepayments (which may be made without penalty) may result in loss of the Fund’s principal investment to the extent of premium paid.

The Fund’s success depends on the Western Asset’s ability to analyze the relationship of changing interest rates on prepayments of the mortgage loans that underlie the Fund’s MBS. Changes in interest rates and prepayments affect the market price of the target assets that the Fund intends to purchase and any target assets that the Fund holds at a given time. As part of the Fund’s overall portfolio risk management, Western Asset will analyze interest rate changes and prepayment trends separately and collectively to assess their effects on the Fund’s investment portfolio. In conducting its analysis, Western Asset will depend on certain assumptions based upon historical trends with respect to the relationship between interest rates and prepayments under normal market conditions. If the recent dislocations in the mortgage market or other developments change the way that prepayment trends have historically responded to interest rate changes, Western Asset’s ability to (1) assess the market value of the Fund’s investment portfolio, (2) implement any hedging strategies and (3) implement techniques to reduce prepayment rate volatility would be significantly affected, which could materially adversely affect the Fund’s financial position and results of operations.

In general, losses on a mortgaged property securing a mortgage loan included in a securitization will be borne first by the equity holder of the property, then by a cash reserve fund or letter of credit, if any, then by the holder of a mezzanine loan or B-Note, if any, then by the “first loss” subordinated security holder (generally, the “B-Piece” buyer) and then by the holder of a higher-rated security. In the event of default and the exhaustion of

51

any equity support, reserve fund, letter of credit, mezzanine loans or B-Notes, and any classes of securities junior to those in which the Fund invests, the Fund will not be able to recover all of its investment in the MBS it purchases. MBS in which the Fund invests may not contain reserve funds, letters of credit, mezzanine loans and/or junior classes of securities.

The prices of lower credit quality securities are generally less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual issuer developments.

MBS generally are classified as either CMBS or RMBS, each of which are subject to certain specific risks as further described below. See “-Non-Agency RMBS Risk” and “-CMBS Risk.”

Non-Agency RMBS Risk

Non-agency RMBS are securities issued by non-governmental issuers, the payments on which depend (except for rights or other assets designed to assure the servicing or timely distribution of proceeds to holders of such securities) primarily on the cash flow from residential mortgage loans made to borrowers that are secured (on a first priority basis or second priority basis, subject to permitted liens, easements and other encumbrances) by residential real estate (one- to four- family properties) the proceeds of which are used to purchase real estate and purchase or construct dwellings thereon (or to refinance indebtedness previously so used). Non-agency RMBS have no direct or indirect government guarantees of payment and are subject to various risks as described herein.

Credit-Related Risk Associated with Borrowers on Non-Agency RMBS. Credit-related risk on non-agency RMBS arises from losses due to delinquencies and defaults by the borrowers in payments on the underlying mortgage loans and breaches by originators and servicers of their obligations under the underlying documentation pursuant to which the non-agency RMBS are issued. Residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The rate of delinquencies and defaults on residential mortgage loans and the aggregate amount of the resulting losses will be affected by a number of factors, including general economic conditions, particularly those in the area where the related mortgaged property is located, the level of the borrower’s equity in the mortgaged property and the individual financial circumstances of the borrower. If a residential mortgage loan is in default, foreclosure on the related residential property may be a lengthy and difficult process involving significant legal and other expenses. The net proceeds obtained by the holder on a residential mortgage loan following the foreclosure on the related property may be less than the total amount that remains due on the loan. The prospect of incurring a loss upon the foreclosure of the related property may lead the holder of the residential mortgage loan to restructure the residential mortgage loan or otherwise delay the foreclosure process.

Impact of Real Estate and Mortgage Loan Markets on Non-Agency RMBS. In addition to the foregoing considerations, the market for defaulted residential mortgage loans and foreclosed real estate properties may be very limited. In particular, the economic conditions that lead to a higher rate of delinquencies and defaults on a portfolio of real estate mortgage loans may also lead to a reduction in the value of the related real estate properties, which in turn will result in greater losses upon a foreclosure of the real estate properties. At any one time, a portfolio of non-agency RMBS may be backed by residential mortgage loans that are highly concentrated in only a few states or regions. As a result, the performance of such residential mortgage loans may be more susceptible to a downturn in the economy, including in particular industries that are highly represented in such states or regions, natural calamities and other adverse conditions affecting such areas. In addition, the residential mortgage loans underlying non-agency RMBS may include so-called “jumbo” residential mortgage loans, having original principal balances that are significantly higher than is generally the case for residential mortgage loans. If the portfolio of residential mortgage loans underlying a non-agency RMBS includes a high concentration of “jumbo” residential mortgage loans, the performance of the non-agency RMBS will be more susceptible to the performance of individual borrowers and adverse economic conditions in general than would otherwise be the case.

52

Another factor that may contribute to, and may in the future result in, higher delinquency and default rates is the increase in monthly payments on adjustable-rate mortgage loans. Any increase in prevailing market interest rates may result in increased payments for borrowers who have adjustable-rate mortgage loans. Moreover, with respect to hybrid mortgage loans after their initial fixed-rate period or other so-called adjustable-rate mortgage loans, interest-only products or products having a lower rate, and with respect to mortgage loans with a negative amortization feature which reach their negative amortization cap, borrowers may experience a substantial increase in their monthly payment even without an increase in prevailing market interest rates. Increases in payments for borrowers may result in increased rates of delinquencies and defaults on residential mortgage loans underlying the non-agency RMBS. The past performance of the market for non-agency RMBS is not a reliable indicator of future performance because of the unprecedented and unpredictable performance of the residential mortgage loan market.

As a result of rising concerns about increases in delinquencies and defaults on residential mortgage loans (particularly on subprime and adjustable-rate mortgage loans) and as a result of increasing concerns about the financial strength of originators and servicers and their ability to perform their obligations with respect to non-agency RMBS, there may be an adverse change in the market sentiments of investors about the market values and volatility and the degree of risk of non-agency RMBS generally. Some or all of the underlying residential mortgage loans in an issue of non-agency RMBS may have balloon payments due on their respective maturity dates. Balloon residential mortgage loans involve a greater risk to a lender than fully amortizing loans, because the ability of a borrower to pay such amount will normally depend on its ability to obtain refinancing of the related mortgage loan or sell the related mortgaged property at a price sufficient to permit the borrower to make the balloon payment, which will depend on a number of factors prevailing at the time such refinancing or sale is required, including, without limitation, the strength of the local or national residential real estate markets, interest rates and general economic conditions and the financial condition of the borrower. If borrowers are unable to make such balloon payments, the related issue of non-agency RMBS may experience losses.

Prepayment Risk Associated with Non-Agency RMBS. Non-agency RMBS are susceptible to prepayment risks. Except in the case of certain types of non-agency RMBS, the mortgage loans underlying non-agency RMBS generally do not contain prepayment penalties and a reduction in market interest rates will increase the likelihood of prepayments on the related non-agency RMBS, resulting in a reduction in yield to maturity for most holders of such securities. In the case of certain home equity loan securities and certain types of non-agency RMBS, even though the underlying mortgage loans often contain prepayment premiums, such prepayment premiums may not be sufficient to discourage borrowers from prepaying their mortgage loans in the event of a reduction in market interest rates, resulting in a reduction in the yield to maturity for holders of the related non-agency RMBS. In addition to reductions in the level of market interest rates and the prepayment provisions of the mortgage loans, repayments on the residential mortgage loans underlying an issue of non-agency RMBS may also be affected by a variety of economic, geographic and other factors, including the size difference between the interest rates on the underlying residential mortgage loans (giving consideration to the cost of refinancing) and prevailing mortgage rates and the availability of refinancing. In general, if prevailing interest rates fall significantly below the interest rates on the related residential mortgage loans, the rate of prepayment on the underlying residential mortgage loans would be expected to increase. Conversely, if prevailing interest rates rise to a level significantly above the interest rates on the related mortgage loans, the rate of prepayment would be expected to decrease. Prepayments could reduce the yield received on the related issue of non-agency RMBS.

Non-agency RMBS typically contain provisions that require repurchase of mortgage loans by the originator or other seller in the event of a breach of a representation or warranty regarding loan quality and characteristics of such loan. Any repurchase of a mortgage loan as a result of a breach has the same effect on the yield received on the related issue of non-agency RMBS as a prepayment of such mortgage loan. Any increase in breaches of representations and the consequent repurchases of mortgage loans that result from inadequate underwriting procedures and policies and protections against fraud will have the same effect on the yield on the related non-agency RMBS as an increase in prepayment rates. CMBS are also subject to prepayment risk, as described above. Risk of prepayment may be reduced for commercial real estate property loans containing significant prepayment penalties or prohibitions on principal payments for a period of time following origination.

53

The Fund may also invest in MBS which are IO securities and PO securities. An IO security receives some or all of the interest portion of the underlying collateral and little or no principal. A reference principal value called a notional value is used to calculate the amount of interest due. IO securities are sold at a deep discount to their notional principal amount. A PO security does not receive any interest, is priced at a deep discount to its redemption value and ultimately receives the redemption value. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of a PO security will rise and the value of an IO security will fall. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of a PO security will fall and the value of an IO security will rise.

Legal Risks Associated with Non-Agency RMBS. Legal risks can arise as a result of the procedures followed in connection with the origination of the mortgage loans or the servicing thereof which may be subject to various federal and state laws (including, without limitation, predatory lending laws), public policies and principles of equity regulating interest rates and other charges, require certain disclosures, require licensing of originators, prohibit discriminatory lending practices, regulate the use of consumer credit information and debt collection practices and may limit the servicer’s ability to collect all or part of the principal of or interest on a residential mortgage loan, entitle the borrower to a refund of amounts previously paid by it or subject the servicer to damages and sanctions. Specifically, provisions of federal predatory lending laws, such as the federal Truth-in-Lending Act (as supplemented by the Home Ownership and Equity Protection Act of 1994) and Regulation Z, and various enacted state predatory lending laws provide that a purchaser or assignee of specified types of residential mortgage loans (including an issuer of non-agency RMBS) may be held liable for violations by the originator of such mortgage loans. Under such assignee liability provisions, a borrower is generally given the right to assert against a purchaser of its mortgage loan any affirmative claims and defenses to payment such borrower could assert against the originator of the loan or, where applicable, the home improvement contractor that arranged the loan. Liability under such assignee liability provisions could, therefore, result in a disruption of cash flows allocated to the holders of non-agency RMBS where either the issuer of such non-agency RMBS is liable in damages or is unable to enforce payment by the borrower. In most but not all cases, the amount recoverable against a purchaser or assignee under such assignee liability provisions is limited to amounts previously paid and still owed by the borrower. Moreover, sellers of residential mortgage loans to an issuer of non-agency RMBS typically represent that the loans have been originated in accordance with all applicable laws and in the event such representation is breached, the seller typically must repurchase the offending loan.

Notwithstanding these protections, an issuer of non-agency RMBS may be exposed to an unquantifiable amount of potential assignee liability because, first, the amount of potential assignee liability under certain predatory lending laws is unclear and has yet to be litigated, and, second, in the event a predatory lending law does not prohibit class action lawsuits, it is possible that an issuer of non-agency RMBS could be liable in damages for more than the original principal amount of the offending loans held by it. In such circumstances the issuer of non-agency RMBS may be forced to seek contribution from other parties, who may no longer exist or have adequate funds available to fund such contribution.

In addition, structural and legal risks of non-agency RMBS include the possibility that, in a bankruptcy or similar proceeding involving the originator or the servicer (often the same entity or affiliates), the assets of the issuer could be treated as never having been truly sold by the originator to the issuer and could be substantively consolidated with those of the originator, or the transfer of such assets to the issuer could be voided as a fraudulent transfer. Challenges based on such doctrines could result also in cash flow delays and losses on the related issue of non-agency RMBS.

In some cases, servicers of non-agency RMBS have been the subject of legal proceedings involving the origination and/or servicing practices of such servicers. Large groups of private litigants and states attorneys general have brought such proceedings. Because of the large volume of mortgage loans originated and serviced by such servicers, such litigation can cause heightened financial strain on servicers. In other cases, origination and servicing practices may cause or contribute to such strain, because of representation and warranty repurchase liability arising in MBS and mortgage loan sale transactions. Any such financial strain could cause servicers to

54

service below required standards, causing delinquencies and losses in any related MBS transaction to rise, and in extreme cases could cause the servicer to seek the protection of any applicable bankruptcy or insolvency law. In any such proceeding, it is unclear whether the fees that the servicer charges in such transactions would be sufficient to permit that servicer or a successor servicer to service the mortgage loans in such transaction adequately. If such fees had to be increased, it is likely that the most subordinated security holders in such transactions would be effectively required to pay such increased fees. Finally, these entities may be the subject of future laws designed to protect consumers from defaulting on their mortgage loans. Such laws may have an adverse effect on the cash flows paid under such non-agency RMBS.

In the past year, a number of lenders specializing in residential mortgages have sought bankruptcy protection, shut down or been refused further financings from their lenders. In addition, certain lenders who service and/or issue non-agency RMBS have announced that they are being investigated by or have received information requests from U.S. federal and/or state authorities, including the Securities and Exchange Commission. As a result of such investigations and other similar investigations and general concerns about the adequacy or accuracy of disclosure of risks to borrowers and their understanding of such risks, U.S. financial regulators have indicated that they may propose new guidelines for the mortgage industry. Guidelines, if introduced, together with the other factors described herein, may make it more difficult for borrowers with weaker credit to refinance, which may lead to further increases in delinquencies, extensions in duration and losses in mortgage-related assets. Furthermore, because some mortgage loans have high recoveries, and as property values decline, increasing loan-to-value ratios, recoveries on some defaulted mortgage loans are more likely to be less than the amounts owed under such mortgage loans, resulting in higher net losses than would have been the case had property values remained the same or increased.

CMBS Risk

CMBS are, generally, securities backed by obligations (including certificates of participation in obligations) that are principally secured by mortgages on real property or interests therein having a multifamily or commercial use, such as regional malls, other retail space, office buildings, industrial or warehouse properties, hotels, nursing homes and senior living centers. The market for CMBS developed more recently and, in terms of total outstanding principal amount of issues, is relatively small compared to the market for residential single-family mortgage-related securities. CMBS are subject to particular risks, including lack of standardized terms, shorter maturities than residential mortgage loans and payment of all or substantially all of the principal only at maturity rather than regular amortization of principal. Additional risks may be presented by the type and use of a particular commercial property. Special risks are presented by hospitals, nursing homes, hospitality properties and certain other property types. Commercial property values and net operating income are subject to volatility, which may result in net operating income becoming insufficient to cover debt service on the related mortgage loan. The repayment of loans secured by income-producing properties is typically dependent upon the successful operation of the related real estate project rather than upon the liquidation value of the underlying real estate. Furthermore, the net operating income from and value of any commercial property is subject to various risks, including changes in general or local economic conditions and/or specific industry segments; the solvency of the related tenants; declines in real estate values; declines in rental or occupancy rates; increases in interest rates, real estate tax rates and other operating expenses; changes in governmental rules, regulations and fiscal policies; acts of God; terrorist threats and attacks and social unrest and civil disturbances. Consequently, adverse changes in economic conditions and circumstances are more likely to have an adverse impact on mortgage-related securities secured by loans on commercial properties than on those secured by loans on residential properties. In addition, commercial lending generally is viewed as exposing the lender to a greater risk of loss than one- to four- family residential lending. Commercial lending, for example, typically involves larger loans to single borrowers or groups of related borrowers than residential one- to four- family mortgage loans. In addition, the repayment of loans secured by income producing properties typically is dependent upon the successful operation of the related real estate project and the cash flow generated therefrom.

55

The exercise of remedies and successful realization of liquidation proceeds relating to CMBS is also highly dependent on the performance of the servicer or special servicer. In many cases, overall control over the special servicing of related underlying mortgage loans will be held by a “directing certificateholder” or a “controlling class representative,” which is appointed by the holders of the most subordinate class of CMBS in such series. The Fund may not have the right to appoint the directing certificateholder. In connection with the servicing of the specially serviced mortgage loans, the related special servicer may, at the direction of the directing certificateholder, take actions with respect to the specially serviced mortgage loans that could adversely affect the Fund’s interests. There may be a limited number of special servicers available, particularly those that do not have conflicts of interest.

Western Asset will value the Fund’s potential CMBS investments based on loss-adjusted yields, taking into account estimated future losses on the mortgage loans included in the securitization’s pool of loans, and the estimated impact of these losses on expected future cash flows. Western Asset’s loss estimates may not prove accurate, as actual results may vary from estimates. In the event that Western Asset overestimates the pool level losses relative to the price the Fund pays for a particular CMBS investment, the Fund may experience losses with respect to such investment.

Interest Rate Risk Associated with Non-Agency RMBS and CMBS

The rate of interest payable on certain non-agency RMBS and CMBS may be set or effectively capped at the weighted average net coupon of the underlying mortgage loans themselves, often referred to as an “available funds cap.” As a result of this cap, the return to the holder of such non-agency RMBS and CMBS is dependent on the relative timing and rate of delinquencies and prepayments of mortgage loans bearing a higher rate of interest. In general, early prepayments will have a greater negative impact on the yield to the holder of such non-agency RMBS and CMBS.

The value of fixed rate debt securities can be expected to vary inversely with changes in prevailing interest rates. Fixed rate debt securities with longer maturities, which tend to produce higher yields, are subject to potentially greater capital appreciation and depreciation than securities with shorter maturities.

Structural Risks Associated with Non-Agency RMBS and CMBS

Because non-agency RMBS generally are ownership or participation interests in pools of mortgage loans secured by a pool of one- to four-family residential properties underlying the mortgage loan pool, the non-agency RMBS are entitled to payments provided for in the underlying agreement only when and if funds are generated by the underlying mortgage loan pool. This likelihood of the return of interest and principal may be assessed as a credit matter. However, the holders of non-agency RMBS do not have the legal status of secured creditors, and cannot accelerate a claim for payment on their securities, or force a sale of the mortgage loan pool in the event that insufficient funds exist to pay such amounts on any date designated for such payment. The holders of non-agency RMBS do not typically have any right to remove a servicer solely as a result of a failure of the mortgage pool to perform as expected. A similar risk is associated with CMBS.

Subordination Risk Associated with Non-Agency RMBS and CMBS

The non-agency RMBS and CMBS may be subordinated to one or more other senior classes of securities of the same series for purposes of, among other things, offsetting losses and other shortfalls with respect to the related underlying mortgage loans. For example, in the case of certain non-agency RMBS and CMBS, no distributions of principal will generally be made with respect to any class until the aggregate principal balances of the corresponding senior classes of securities have been reduced to zero. As a result, non-agency RMBS and CMBS may be more sensitive to risk of loss, writedowns, the non-fulfillment of repurchase obligations, overadvancing on a pool of loans and the costs of transferring servicing than senior classes of securities.

Credit Risk and Counterparty Risk

Credit risk is the risk that one or more MBS or other securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. In general, lower-rated securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund’s net asset value or dividends and on the market price of the Common Stock. Ratings may not accurately reflect the actual credit risk associated with a security. If a security satisfies the rating requirements described above at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, FTFA and Western Asset will consider what action, including the sale of the security, is in the best interests of the Fund and its stockholders. There can be no assurance that any action that may be taken by FTFA or Western Asset will be implemented in a timely manner or that such actions will preserve the value of your investment in the Fund. Securities of below investment grade quality, commonly referred to as junk bonds, are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal when due, and are more susceptible to default or decline in market value due to adverse economic and business developments than investment grade securities. Also, to the extent that the rating assigned to a security in the Fund’s portfolio is downgraded by any NRSRO, the market price and liquidity of such security may be adversely affected. The market values for securities of below investment grade quality tend to be volatile, and these securities are less liquid than investment grade securities, potentially making them difficult to value. Issuers of below investment grade securities are more vulnerable to financial setbacks and recession than more creditworthy issuers, which may impair their ability to make interest and principal payments. It is likely that the current economic recession may severely disrupt the market for such securities and have an adverse impact on the value of such securities. In addition, it is likely that continued economic deterioration may adversely affect the ability of such issuers to repay principal and pay interest on these securities and increase the incidence of default for such securities. For these reasons, an investment in the Fund, compared with a portfolio consisting solely of investment grade securities, may experience the following:

Adverse changes in economic conditions are more likely to lead to a weakened capacity of a below investment grade issuer to make principal payments and interest payments compared to an investment grade issuer. The principal amount of below investment grade securities outstanding has proliferated in the past decade as an increasing number of issuers have used below investment grade securities for financing. The current economic downturn may severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. If the current economic downturn continues or worsens, or in the event interest rates rise sharply, increasing the interest cost on variable rate instruments and negatively impacting economic activity, the number of defaults by below investment grade issuers is likely to increase. Similarly, down-turns in profitability in specific industries could adversely affect private activity bonds. The market values of lower quality debt securities tend to reflect the individual circumstances of the issuer to a greater extent than do higher quality securities, which react primarily to fluctuations in the general level of interest rates. Factors having an adverse impact on the market value of lower quality securities may have an adverse impact on the Fund’s net asset value and the market value of its Common Stock. In addition, the Fund may incur additional

57

expenses to the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. In certain circumstances, the Fund may be required to foreclose on an issuer’s assets and take possession of its property or operations. In such circumstances, the Fund would incur additional costs in disposing of such assets and potential liabilities from operating any business acquired.

The secondary market for below investment grade securities may not be as liquid as the secondary market for more highly rated securities, a factor that may have an adverse effect on the Fund’s ability to dispose of a particular security. There are fewer dealers in the market for below investment grade securities than in the market for investment grade securities. The prices quoted by different dealers for below investment grade securities may vary significantly, and the spread between the bid and ask price is generally much larger for below investment grade securities than for higher quality instruments. Under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under such circumstances, may be less than the prices used in calculating the Fund’s net asset value.

Issuers of below investment grade securities are highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with higher rated securities. For example, during an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of below investment grade securities may experience financial stress. During such periods, such issuers may not have sufficient revenues to meet their interest payment obligations. An issuer’s ability to service its debt obligations also may be adversely affected by adverse developments in its business or affairs, the issuer’s inability to meet specific projected forecasts or the unavailability of additional financing. The risk of loss from default by the issuer is significantly greater for the holders of below investment grade securities because such securities are generally unsecured and are often subordinated to other creditors of the issuer. Prices and yields of below investment grade securities will fluctuate over time and, during periods of economic uncertainty, volatility of below investment grade securities may adversely affect the Fund’s net asset value. In addition, investments in below investment grade zero coupon bonds rather than income-bearing below investment grade securities, may be more speculative and may be subject to greater fluctuations in value due to changes in interest rates.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto, and the federal income tax consequences to the Fund as a holder of such securities may not be clear.

Interest Rate Risk

Interest rate risk is the risk that the debt securities in the Fund’s portfolio will decline in value because of changes in market interest rates. As interest rates decline, issuers of securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. In typical market interest rate environments, the prices of longer-term debt securities generally fluctuate more than the prices of shorter-term debt securities as interest rates change. To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor, the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Interest rates are currently low relative to historic levels. The FOMC of the U.S. Federal Reserve has set its target federal funds rate at which depository institutions lend reserve balances to other depository institutions overnight to at or near zero percent and the U.S. Federal Reserve has expanded its balance sheet to increase its purchases of debt securities. In the future, the FOMC may increase or decrease the target federal funds rate, and the U.S. Federal Reserve may increase, decrease or eliminate its purchases of debt securities.

58

Moreover, because rates on certain floating rate debt securities in which the Fund may invest typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the Fund’s net asset value. The Fund may utilize certain strategies, including taking positions in futures or interest rate swaps, for the purpose of reducing the interest rate sensitivity of the Fund’s debt securities and decreasing the Fund’s exposure to interest rate risk. The Fund is not required to hedge its exposure to interest rate risk and may choose not to do so. In addition, there is no assurance that any attempts by the Fund to reduce interest rate risk will be successful.

An increase in the interest payments on the Fund’s borrowings relative to the interest it earns on its investment securities may adversely affect the Fund’s profitability. The Fund earns money based upon the spread between the interest payments it earns on its investment securities and the interest payments it must make on its borrowings.

The Fund relies primarily on short-term borrowings to acquire investment securities with long-term maturities. Accordingly, if short-term interest rates increase, this may adversely affect its profitability. Some of the investment securities the Fund may acquire are adjustable-rate securities. This means that their interest rates may vary over time based upon changes in an objective index, such as:

These indices generally reflect short-term interest rates.

The interest rates on the Fund’s borrowings similarly vary with changes in an objective index. Nevertheless, the interest rates on the Fund’s borrowings generally adjust more frequently than the interest rates on its adjustable-rate investment securities. In a period of rising interest rates, the Fund could experience a decrease in net income or a net loss because the interest rates on its borrowings adjust faster than the interest rates on its adjustable-rate investment securities.

In a period of rising interest rates, the Fund’s interest and dividend payments could increase while the interest it earns on its fixed-rate MBS would not change. This would adversely affect the Fund’s profitability.

Rising interest rates generally reduce the demand for mortgage loans due to the higher cost of borrowing. A reduction in the volume of mortgage loans originated may affect the volume of target assets available to the Fund, which could adversely affect the Fund’s ability to acquire assets that satisfy its investment objectives. Rising interest rates may also cause target assets that were issued prior to an interest rate increase to provide yields that are below prevailing market interest rates. If rising interest rates cause the Fund to be unable to acquire a sufficient volume of target assets with a yield that is above the Fund’s borrowing cost, its ability to satisfy its investment objectives and to generate income and make distributions may be materially and adversely affected.

The relationship between short-term and longer-term interest rates is often referred to as the “yield curve.” Ordinarily, short-term interest rates are lower than longer-term interest rates. If short-term interest rates rise disproportionately relative to longer-term interest rates (a flattening of the yield curve), the Fund’s borrowing costs may increase more rapidly than the interest income earned on the Fund’s assets. Because the Fund expects that its investments, on average, generally will bear interest based on longer-term rates than its borrowings, a

59

flattening of the yield curve would tend to decrease the Fund’s net income and the market value of its net assets. Additionally, to the extent cash flows from investments that return scheduled and unscheduled principal are reinvested, the spread between the yields on the new investments and available borrowing rates may decline, which would likely decrease the Fund’s net income. It is also possible that short-term interest rates may exceed longer-term interest rates (a yield curve inversion) in which event the Fund’s borrowing costs may exceed its interest income and the Fund could incur operating losses.

Leverage Risk

The Fund may seek to enhance the level of its current distributions to holders of Common Stock through the use of leverage. The Fund may use leverage directly at the Fund level.

The Fund also may establish a standby credit facility in an amount up to 5% of Managed Assets as a temporary measure for purposes of making distributions to stockholders in order to maintain its favorable tax treatment as a regulated investment company. In addition, the Fund may borrow for temporary, emergency or other purposes as permitted under the 1940 Act. Any such indebtedness would be in addition to the combined direct and implicit leverage ratio of up to 33 ¹/₃% of the Fund’s total net assets.

The Fund will pay (and Common Stockholders will bear) any costs and expenses relating to the use of leverage by the Fund, to the extent the Fund bears such costs, which will result in a reduction in the net asset value of the Common Stock.

Leverage may result in greater volatility of the net asset value and market price of, and distributions on, the Common Stock because changes in the value of the Fund’s portfolio investments, including investments purchased with the proceeds from Borrowings or the issuance of Preferred Stock, if any, are borne entirely by Common Stockholders. Common Stock income may fall if the interest rate on Borrowings or the dividend rate on Preferred Stock rises, and may fluctuate as the interest rate on Borrowings or the dividend rate on Preferred Stock varies. So long as the Fund is able to realize a higher net return on its investment portfolio than the then-current cost of any leverage together with other related expenses, the effect of the leverage will be to cause Common Stockholders to realize higher current net investment income than if the Fund were not so leveraged. On the other hand, the Fund’s use of leverage will result in increased operating costs. Thus, to the extent that the then-current cost of any leverage, together with other related expenses, approaches the net return on the Fund’s investment portfolio, the benefit of leverage to Common Stockholders will be reduced, and if the then-current cost of any leverage together with related expenses were to exceed the net return on the Fund’s portfolio, the Fund’s leveraged capital structure would result in a lower rate of return to Common Stockholders than if the Fund were not so leveraged. There can be no assurance that the Fund’s leveraging strategy will be successful.

During periods when the Fund is using leverage through Borrowings or the issuance of Preferred Stock, the fees paid to FTFA, Western Asset, and Western Asset Limited for advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund’s Managed Assets, which includes the amount of Borrowings and any assets attributable to Preferred Stock. This means that FTFA, Western Asset and Western Asset Limited may have a financial incentive to increase the Fund’s use of leverage.

Any decline in the net asset value of the Fund will be borne entirely by Common Stockholders. Therefore, if the market value of the Fund’s portfolio declines, the Fund’s use of leverage will result in a greater decrease in net asset value to Common Stockholders than if the Fund were not leveraged. Such greater net asset value decrease will also tend to cause a greater decline in the market price for the Common Stock.

Certain types of Borrowings may result in the Fund being subject to covenants in credit agreements relating to asset coverage or portfolio composition or otherwise. In addition, the terms of the credit agreements may also require that the Fund pledge some or all of its assets as collateral. In addition, the Fund may be subject to certain

60

restrictions imposed by guidelines of one or more rating agencies which may issue ratings for commercial paper or notes issued by the Fund. Such restrictions may be more stringent than those imposed by the 1940 Act.

The current weakness in the financial markets, the residential and commercial mortgage markets and the economy could adversely affect one or more of the Fund’s potential lenders and could cause one or more of the Fund’s potential lenders to be unwilling or unable to provide the Fund with financing or to increase the costs of that financing. Current market conditions have affected different types of financing for mortgage-related assets to varying degrees, with some sources generally being unavailable, others being available but at a higher cost, while others are largely unaffected. For example, in the repurchase agreement market, non-agency RMBS, which are securities created by private entities, have been more difficult to finance than agency RMBS, which are securities created by government agencies. Repurchase agreement counterparties have generally increased haircuts, which are the percentages that represent how much the amount of the loan is less than the value of the collateral securing the loan. Repurchase agreement counterparties have taken these steps in order to compensate themselves for a perceived increased risk due to the illiquidity of the underlying collateral. In some cases, margin calls have forced borrowers to liquidate collateral in order to meet the capital requirements of these margin calls, resulting in losses.

The return on the Fund’s assets and cash available for distribution to Common Stockholders may be reduced to the extent that market conditions prevent the Fund from leveraging assets or cause the cost of the Fund’s financing to increase relative to the income that can be derived from the assets acquired. The Fund’s financing costs will reduce cash available for distributions to Common Stockholders. The Fund may not be able to meet its financing obligations and, to the extent that it cannot, it risks the loss of some or all of its assets to liquidation or sale to satisfy the obligations under its repurchase agreements. A decrease in the value of these assets may lead to margin calls which the Fund will have to satisfy. The Fund may not have the funds available to satisfy any such margin calls and may be forced to sell assets at significantly depressed prices due to market conditions or otherwise, which may result in losses. The satisfaction of such margin calls may reduce cash flow available for distribution to Common Stockholders. Any reduction in distributions to Common Stockholders may cause the value of the Fund’s Common Stock to decline.

ABS Risk

The Fund may invest up to 20% of its Managed Assets in non-mortgage related ABS. Investing in ABS entails various risks, including credit risks, liquidity risks, interest rate risks, market risks and legal risks. Credit risk is an important issue in ABS because of the significant credit risks inherent in the underlying collateral and because issuers are primarily private entities. The structure of an ABS and the terms of the investors’ interest in the collateral can vary widely depending on the type of collateral, the desires of investors and the use of credit enhancements. Although the basic elements of all ABS are similar, individual transactions can differ markedly in both structure and execution. Important determinants of the risk associated with issuing or holding the securities include the process by which principal and interest payments are allocated and distributed to investors, how credit losses affect the issuing vehicle and the return to investors in such ABS, whether collateral represents a fixed set of specific assets or accounts, whether the underlying collateral assets are revolving or closed-end, under what terms (including the maturity of the ABS itself) any remaining balance in the accounts may revert to the issuing entity and the extent to which the entity that is the actual source of the collateral assets is obligated to provide support to the issuing vehicle or to the investors in such ABS. The Fund may invest in ABS that are subordinate in right of payment and rank junior to other securities that are secured by or represent an ownership interest in the same pool of assets. In addition, many of the transactions in which such securities are issued have structural features that divert payments of interest and/or principal to more senior classes when the delinquency or loss experience of the pool exceeds certain levels. As a result, such securities have a higher risk of loss as a result of delinquencies or losses on the underlying assets.

61

Below Investment Grade (“High Yield” or “Junk”) Securities Risk

A significant portion of the Fund’s portfolio may consist of below investment grade securities (high yield securities). The Fund invests a substantial portion of its assets in MBS that were originally rated AAA, but subsequently have been downgraded to below investment grade. High yield debt securities are generally subject to greater credit risks than higher-grade debt securities, including the risk of default on the payment of interest or principal. High yield debt securities are considered speculative, typically have lower liquidity and are more difficult to value than higher grade bonds. High yield debt securities tend to be volatile and more susceptible to adverse events, credit downgrades and negative sentiments and may be difficult to sell at a desired price, or at all, during periods of uncertainty or market turmoil.

Distressed Investments

The Fund invests in distressed securities, which are securities and obligations of companies that are experiencing financial or business difficulties. Distressed investments may result in significant returns to the Fund, but also involve a substantial degree of risk. Among the risks inherent in distressed situations is the fact that it frequently may be difficult to obtain information as to the true condition of the securities being purchased. The market prices of distressed securities are also subject to abrupt and erratic market movements and above average price volatility, and the spread between the bid and asked prices of such securities may be greater than normally experienced.

The Fund intends to invest in distressed investments including non-performing and sub-performing RMBS and CMBS, many of which are not publicly traded and which may involve a substantial degree of risk. In certain periods, there may be little or no liquidity in the markets for these securities or instruments. In addition, the prices of such securities or instruments may be subject to periods of abrupt and erratic market movements and above-average price volatility. It may be more difficult to value such securities and the spread between the bid and asked prices of such securities may be greater than normally expected. If the Western Asset’s evaluation of the risks and anticipated outcome of an investment in a distressed security should prove incorrect, the Fund may lose a substantial portion or all of its investment.

Furthermore, investments in assets operating in workout modes or under Chapter 11 of the United States Bankruptcy Code, as amended, and other comparable bankruptcy laws may, in certain circumstances, be subject to certain additional potential liabilities that may exceed the value of the Fund’s original investment. For example, under certain circumstances, lenders who have inappropriately exercised control of the management and policies of a debtor may have their claims subordinated or disallowed or counterclaims may be filed and lenders may be found liable for damages suffered by various parties as a result of such actions. In addition, under certain circumstances, payments to the Fund and distributions by the Fund to its investors may be reclaimed if any such payment or distribution is later determined to have been a fraudulent conveyance or a preferential payment.

The Fund is not limited in its ability to invest in distressed investments.

Credit Risk Associated with Originators and Servicers of Residential and Commercial Mortgage Loans

A number of originators and servicers of residential and commercial mortgage loans, including some of the largest originators and servicers in the residential and commercial mortgage loan market, have experienced serious financial difficulties, including some that are now subject to federal insolvency proceedings. These difficulties have resulted from many factors, including increased competition among originators for borrowers, decreased originations by such originators of mortgage loans and increased delinquencies and defaults on such mortgage loans, as well as from increases in claims for repurchases of mortgage loans previously sold by them under agreements that require repurchase in the event of breaches of representations regarding loan quality and characteristics. Such difficulties may affect the performance of non-agency RMBS and CMBS backed by

62

mortgage loans. Furthermore, the inability of the originator to repurchase such mortgage loans in the event of loan representation breaches or the servicer to repurchase such mortgage loans upon a breach of its servicing obligations also may affect the performance of related non-agency RMBS and CMBS. Delinquencies and losses on, and, in some cases, claims for repurchase by the originator of, mortgage loans originated by some mortgage lenders have increased as a result of inadequate underwriting procedures and policies, including inadequate due diligence, failure to comply with predatory and other lending laws and, particularly in the case of any “no documentation” or “limited documentation” mortgage loans that may support non-agency RMBS, inadequate verification of income and employment history. Delinquencies and losses on, and claims for repurchase of, mortgage loans originated by some mortgage lenders have also resulted from fraudulent activities of borrowers, lenders, appraisers, and other residential mortgage industry participants such as mortgage brokers, including misstatements of income and employment history, identity theft and overstatements of the appraised value of mortgaged properties. Many of these originators and servicers are very highly leveraged. These difficulties may also increase the chances that these entities may default on their warehousing or other credit lines or become insolvent or bankrupt and thereby increase the likelihood that repurchase obligations will not be fulfilled and the potential for loss to holders of non-agency RMBS, CMBS and subordinated security holders.

The servicers of non-agency RMBS and CMBS are often the same entities as, or affiliates of, the originators of these mortgage loans. Accordingly, the financial risks relating to originators of non-agency RMBS and CMBS described immediately above also may affect the servicing of non-agency RMBS and CMBS. In the case of such servicers, and other servicers, financial difficulties may have a negative effect on the ability of servicers to pursue collection on mortgage loans that are experiencing increased delinquencies and defaults and to maximize recoveries on sale of underlying properties following foreclosure.

Non-agency RMBS and CMBS typically provide that the servicer is required to make advances in respect of delinquent mortgage loans. However, servicers experiencing financial difficulties may not be able to perform these obligations or obligations that they may have to other parties of transactions involving these securities. Like originators, these entities are typically very highly leveraged. Such difficulties may cause servicers to default under their financing arrangements. In certain cases, such entities may be forced to seek bankruptcy protection. Due to the application of the provisions of bankruptcy law, servicers who have sought bankruptcy protection may not be required to advance such amounts. Even if a servicer were able to advance amounts in respect of delinquent mortgage loans, its obligation to make such advances may be limited to the extent that it does not expect to recover such advances due to the deteriorating credit of the delinquent mortgage loans or declining value of the related mortgaged properties. Moreover, servicers may overadvance against a particular mortgage loan or charge too many costs of resolution or foreclosure of a mortgage loan to a securitization, which could increase the potential losses to holders of non-agency RMBS and CMBS. In such transactions, a servicer’s obligation to make such advances may also be limited to the amount of its servicing fee. In addition, if an issue of non-agency RMBS and CMBS provides for interest on advances made by the servicer, in the event that foreclosure proceeds or payments by borrowers are not sufficient to cover such interest, such interest will be paid to the servicer from available collections or other mortgage income, thereby reducing distributions made on the non-agency RMBS and CMBS and, in the case of senior-subordinated non-agency RMBS and CMBS described below, first from distributions that would otherwise be made on the most subordinated non-agency RMBS and CMBS of such issue. Any such financial difficulties may increase the possibility of a servicer termination and the need for a transfer of servicing and any such liabilities or inability to assess such liabilities may increase the difficulties and costs in affecting such transfer and the potential loss, through the allocation of such increased cost of such transfer, to subordinated security holders.

There can be no assurance that originators and servicers of mortgage loans will not continue to experience serious financial difficulties or experience such difficulties in the future, including becoming subject to bankruptcy or insolvency proceedings, or that underwriting procedures and policies and protections against fraud will be sufficient in the future to prevent such financial difficulties or significant levels of default or delinquency on mortgage loans. Because the recent financial difficulties experienced by such originators and services is unprecedented and unpredictable, the past performance of the residential and commercial mortgage loans

63

originated and serviced by them (and the corresponding performance of the related non-agency RMBS and CMBS) is not a reliable indicator of the future performance of such residential mortgage loans (or the related non-agency RMBS and CMBS).

Subprime Mortgage Market Risk

The residential mortgage market in the United States has experienced difficulties that may adversely affect the performance and market value of certain mortgages and mortgage-related securities. Delinquencies and losses on residential mortgage loans (especially subprime and second-line mortgage loans) generally have increased and may continue to increase, and a decline in or flattening of housing values (as has been experienced and may continue to be experienced in many housing markets) may exacerbate such delinquencies and losses. Borrowers with adjustable rate mortgage loans are more sensitive to changes in interest rates, which affect their monthly mortgage payments, and may be unable to secure replacement mortgages at comparably low interest rates. Also, a number of residential mortgage loan originators have experienced serious financial difficulties or bankruptcy. Largely due to the foregoing, reduced investor demand for mortgage loans and mortgage-related securities and increased investor yield requirements have caused limited liquidity in the secondary market for mortgage-related securities, which can adversely affect the market value of mortgage-related securities. It is possible that such limited liquidity in such secondary markets could continue or worsen.

The Fund may acquire non-agency RMBS backed by collateral pools of mortgage loans that have been originated using underwriting standards that are less restrictive than those used in underwriting “prime mortgage loans” and “Alt-A mortgage loans.” These lower standards include mortgage loans made to borrowers having imperfect or impaired credit histories, mortgage loans where the amount of the loan at origination is 80% or more of the value of the mortgage property, mortgage loans made to borrowers with low credit scores, mortgage loans made to borrowers who have other debt that represents a large portion of their income and mortgage loans made to borrowers whose income is not required to be disclosed or verified. Due to economic conditions, including increased interest rates and lower home prices, as well as aggressive lending practices, subprime mortgage loans have in recent periods experienced increased rates of delinquency, foreclosure, bankruptcy and loss, and they are likely to continue to experience delinquency, foreclosure, bankruptcy and loss rates that are higher, and that may be substantially higher, than those experienced by mortgage loans underwritten in a more traditional manner. Thus, because of the higher delinquency rates and losses associated with subprime mortgage loans, the performance of non-agency RMBS backed by subprime mortgage loans that the Fund may acquire could be correspondingly adversely affected, which could adversely impact the Fund’s results of operations, financial condition and business.

If the economy of the United States further deteriorates, the incidence of mortgage foreclosures, especially subprime mortgages, may continue to increase, which may adversely affect the value of any MBS owned by the Fund. The U.S. Congress and various government regulatory authorities have discussed the possibility of restructuring mortgages and imposing forbearance requirements on defaulted mortgages. Neither FTFA nor Western Asset can predict the form any such modifications, forbearance or related regulations might take, and these regulations may adversely affect the value of MBS owned by the Fund.

Risks Relating to Investments in Mortgage Whole Loans

Credit Risk Associated With Investments in Mortgage Whole Loans

The holder of residential and commercial mortgages assumes the risk that the related borrowers may default on their obligations to make full and timely payments of principal and interest. In general, these investments carry greater investment risk than agency MBS/CMBS because the former are not guaranteed as to principal or interest by the U.S. Government, any federal agency or any federally chartered corporation. As a result, a mortgage whole loan is directly exposed to losses resulting from default and foreclosure. Therefore, the value of the underlying property, the creditworthiness and financial position of the borrower, and the priority and

64

enforceability of the lien are each of great importance. Whether or not Franklin Templeton, Western Asset or their affiliates have participated in the negotiation of the terms of any such mortgages, there can be no assurance as to the adequacy of the protection of the terms of the loan, including the validity or enforceability of the loan and the maintenance of the anticipated priority and perfection of the applicable security interests. Furthermore, claims may be asserted that might interfere with enforcement of the rights of the Fund. In the event of a foreclosure, the Fund may assume direct ownership of the underlying real estate. The liquidation proceeds upon sale of such real estate may not be sufficient to recover the Fund’s cost basis in the loan, resulting in a loss to the Fund. Any costs or delays involved in the effectuation of a foreclosure of the loan or a liquidation of the underlying property will further reduce the proceeds and thus increase the loss.

Higher-than-expected rates of default and/or higher-than-expected loss severities on these investments could adversely affect the value of these assets. Accordingly, defaults in the payment of principal and/or interest on the Fund’s residential and commercial whole loans would likely result in the Fund incurring losses of income from, and/or losses in market value relating to, these assets, which could materially adversely affect the Fund’s results of operations.

Holders of residential and commercial whole loans are subject to the risk that the related borrowers may default or have defaulted on their obligations to make full and timely payments of principal and interest. A number of factors impact a borrower’s ability to repay including, among other things, changes in employment status, changes in interest rates or the availability of credit, and changes in real estate values. In addition to the credit risk associated with these assets, residential and commercial whole loans are less liquid than certain of the Fund’s other credit sensitive assets, which may make them more difficult to dispose of if the need or desire arises. If actual results are different from the Fund’s assumptions in determining the prices paid to acquire such loans, particularly if the market value of the underlying properties decreases significantly subsequent to purchase, we may incur significant losses, which could materially adversely affect the Fund’s results.

Servicing-Related Risks of Mortgage Whole Loans

We rely on third-party servicers to service and manage the mortgages underlying the Fund’s loan portfolio. The ultimate returns generated by these investments may depend on the quality of the servicer. If a servicer is not vigilant in seeing that borrowers make their required monthly payments, borrowers may be less likely to make these payments, resulting in a higher frequency of default. If a servicer takes longer to liquidate non-performing mortgages, the Fund’s losses related to those loans may be higher than originally anticipated. Any failure by servicers to service these mortgages and/or to competently manage and dispose of REO properties could negatively impact the value of these investments and the Fund’s financial performance. In addition, while we have contracted with third-party servicers to carry out the actual servicing of the loans (including all direct interface with the borrowers), for loans that we purchase together with the related servicing rights, we are nevertheless ultimately responsible, vis-à-vis the borrowers and state and federal regulators, for ensuring that the loans are serviced in accordance with the terms of the related notes and mortgages and applicable law and regulation. In light of the current regulatory environment, such exposure could be significant even though we might have contractual claims against the Fund’s servicers for any failure to service the loans to the required standard.

The foreclosure process, especially in judicial foreclosure states such as New York, Florida and New Jersey, can be lengthy and expensive, and the delays and costs involved in completing a foreclosure, and then subsequently liquidating the REO property through sale, may materially increase any related loss. In addition, at such time as title is taken to a foreclosed property, it may require more extensive rehabilitation than we estimated at acquisition. Thus, a material amount of foreclosed residential mortgage loans, particularly in the states mentioned above, could result in significant losses in the Fund’s residential and commercial whole loan portfolio and could materially adversely affect the Fund’s results of operations.

65

Prepayment Risk Associated With Investments in Mortgage Whole Loans

The residential and commercial whole loans we acquire are backed by pools of residential and commercial mortgage loans. We receive payments, generally, from the payments that are made on these underlying residential and commercial mortgage loans. While commercial mortgages frequently include limitations on the ability of the borrower to prepay, Residential and Commercial mortgages generally do not. When borrowers prepay their residential and commercial mortgage loans at rates that are faster than expected, the net result is prepayments that are faster than expected on the residential and commercial whole loans. These faster than expected payments may adversely affect the Fund’s profitability.

We may purchase residential and commercial whole loans that have a higher interest rate than the then prevailing market interest rate. In exchange for this higher interest rate, we may pay a premium to par value to acquire the asset. In accordance with accounting rules, we amortize this premium over the expected term of the asset based on the Fund’s prepayment assumptions. If the asset is prepaid in whole or in part at a faster than expected rate, however, we must expense all or a part of the remaining unamortized portion of the premium that was paid at the time of the purchase, which will adversely affect the Fund’s profitability.

Prepayment rates generally increase when interest rates fall and decrease when interest rates rise, but changes in prepayment rates are difficult to predict. House price appreciation, while increasing the value of the collateral underlying the Fund’s residential and commercial whole loans, may increase prepayment rates as borrowers may be able to refinance at more favorable terms. Prepayments can also occur when borrowers default on their residential and commercial mortgages and the mortgages are prepaid from the proceeds of a foreclosure sale of the property (an involuntary prepayment), or when borrowers sell the property and use the sale proceeds to prepay the mortgage as part of a physical relocation. Prepayment rates also may be affected by conditions in the housing and financial markets, increasing defaults on Residential and Commercial mortgage loans, which could lead to an acceleration of the payment of the related principal, general economic conditions and the relative interest rates on fixed-rate mortgages and ARMs. While we seek to manage prepayment risk, in selecting residential and commercial whole loans investments we must balance prepayment risk against other risks, the potential returns of each investment and the cost of hedging the Fund’s risks. No strategy can completely insulate us from prepayment or other such risks, and we may deliberately retain exposure to prepayment or other risks.

In addition, a decrease in prepayment rates may adversely affect the Fund’s profitability. When borrowers prepay their residential and commercial mortgage loans at slower than expected rates, prepayments on the residential and commercial whole loans may be slower than expected. These slower than expected payments may adversely affect the Fund’s profitability. We may purchase residential and commercial whole loans that have a lower interest rate than the then prevailing market interest rate. In exchange for this lower interest rate, we may pay a discount to par value to acquire the asset. In accordance with accounting rules, we accrete this discount over the expected term of the asset based on the Fund’s prepayment assumptions. If the asset is prepaid at a slower than expected rate, however, we must accrete the remaining portion of the discount at a slower than expected rate. This will extend the expected life of the asset and result in a lower than expected yield on assets purchased at a discount to par.

Geographic Focus Risk Associated With Residential and Commercial Whole Loans

The Fund’s performance depends on the economic conditions in markets in which the properties securing the mortgage loans underlying the Fund’s investments are concentrated. A substantial portion of the Fund’s portfolio securities may have underlying properties concentrated in specific geographies, including California. The Fund’s financial condition, results of operations, the market price of the Fund’s common stock and the Fund’s ability to make distributions to the Fund’s stockholders could be materially and adversely affected by this geographic focus if market conditions, such as an oversupply of space or a reduction in demand for real estate in an area, deteriorate in California. Moreover, due to the geographic concentration of properties securing the mortgages underlying the Fund’s investments, the Fund may be disproportionately affected by general risks

66

such as natural disasters, including major wildfires, floods and earthquakes, severe or inclement weather, and acts of terrorism should such developments occur in or near the markets in California in which such properties are located.

Other Risks Associated with Mortgage Whole Loans

Mortgage whole loans have risks above and beyond those discussed above. For example, mortgage whole loans are subject to “special hazard” risk (property damage caused by hazards, such as earthquakes or environmental hazards, not covered by standard property insurance policies) and to bankruptcy risk (reduction in a borrower’s mortgage debt by a bankruptcy court). In addition, claims may be assessed against the Fund on account of its position as mortgage holder or property owner, including responsibility for tax payments, environmental hazards and other liabilities.

Tax Risks

To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, among other things, the Fund must derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy certain distribution and asset diversification requirements. If for any taxable year the Fund does not qualify for treatment as a regulated investment company, all of its taxable income (including its net capital gain) would be subject to U.S. federal income tax (and possible state income tax) at regular corporate rates without any deduction for distributions to stockholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current or accumulated earnings and profits.

Risk of Taxable Income in Excess of Economic Income. The Fund expects to acquire debt instruments in the secondary market for less than their stated redemption price at maturity (or, in the case of debt instruments issued with original issue discount, their revised issue price). The discount at which such debt instruments are acquired may reflect doubts about their ultimate collectability rather than current market interest rates. The amount of such discount will nevertheless generally be treated as “market discount” for U.S. federal income tax purposes, subject to a de minimis exception. Market discount on a debt instrument accrues ratably on a daily basis, unless an election is made to accrue market discount on the basis of the constant yield to maturity of the debt instrument, based generally on the assumption that all future payments on the debt instrument will be made. The Fund has made an election to accrue market discount on a current basis, and accrued market discount for a debt instrument will generally have to be included in income each year as if the debt instrument were assured of ultimately being collected in full.

Similarly, many of the debt instruments (including MBS) that the Fund purchases will likely have been issued with original issue discount (“OID”), which discount might reflect doubt as to whether the entire principal amount of such debt instruments will ultimately prove to be collectible. The Fund will be required to report such OID based on a constant yield method and income will be accrued and be currently taxable based on the assumption that all future projected payments due on such debt instruments will be made.

Finally, in the event that any debt instruments (including MBS) acquired by the Fund are delinquent as to mandatory principal and interest payments, or in the event payments with respect to a particular debt instrument are not made when due, the Fund may nonetheless be required to continue to recognize the unpaid interest as taxable income as it accrues, despite doubt as to its ultimate collectability. Similarly, the Fund may be required to accrue interest income with respect to subordinated MBS at the stated rate regardless of whether corresponding cash payments are received or are ultimately collectible.

Status as Regulated Investment Company. As described under the heading “Certain United States Federal Income Tax Considerations,” the Fund must satisfy, among other requirements, an asset diversification test in order to qualify as a regulated investment company under Subchapter M of the Code. Under that test, the Fund must diversify its holdings so that, at the end of each quarter of each taxable year, (i) at least 50% of the value of

67

the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of a single issuer, or two or more issuers that the Fund controls and are engaged in the same, similar or related trades or businesses, or the securities of one or more qualified publicly traded partnerships.

If the Fund fails to satisfy as of the close of any quarter the asset diversification test referred to in the preceding paragraph, it will have 30 days to cure the failure by, for example, selling securities that are the source of the violation. Other cure provisions are available in the Code for a failure to satisfy the asset diversification test, but any such cure provision may involve the payment of a penalty excise tax. If the Fund fails to cure an asset diversification violation, it may lose its status as a regulated investment company under the Code. In that case, all of its taxable income would be subject to U.S. federal income tax (and possible state income tax) at regular corporate rates without any deduction for distributions to stockholders. In addition, all distributions (including distributions of net capital gain) would be taxed to the Fund’s Common Stockholders as ordinary dividend income to the extent of the Fund’s current or accumulated earnings and profits. Accordingly, disqualification as a regulated investment company could have a material adverse effect on the value of the Fund’s Common Stock and the amount of Fund distributions.

Risks Associated with the Fund’s Ability To Satisfy Regulated Investment Company Distribution Requirements. The Fund generally must distribute annually at least 90% of its taxable income, excluding any net capital gain, in order to maintain its treatment as a regulated investment company for U.S. federal income tax purposes. To the extent that the Fund satisfies this distribution requirement, but distributes less than 100% of its taxable income and net capital gain, the Fund will be subject to U.S. federal corporate income tax on the Fund’s undistributed taxable income. In addition, the Fund will be subject to a 4% nondeductible excise tax if the actual amount that the Fund distributes to its stockholders in a calendar year is less than a minimum amount specified under U.S. federal income tax laws. The Fund intends to make distributions to its stockholders to comply with the requirements of the Code and to avoid paying U.S. federal income taxes and, if practicable, excise taxes, on undistributed taxable income. However, differences in timing between the recognition of taxable income and the actual receipt of cash could require the Fund to sell assets (including (i) cash, (ii) bank deposits, (iii) Treasury securities with maturities of not more than 90 calendar days, (iv) money market mutual funds that (a) are registered with the SEC and regulated under Rule 2a-7 promulgated under the 1940 Act and (b) invest exclusively in direct obligations of the United States or obligations the prompt payment of the principal of and interest on which is unconditionally guaranteed by the United States, (v) repurchase agreements secured by Treasury securities (if permitted by the Treasury) and (vi) any other investment approved by the Treasury in writing) or borrow funds on a short-term or long-term basis or issue cash-stock dividends (described below) to meet the distribution requirements of the Code.

The Fund may find it difficult or impossible to meet distribution requirements in certain circumstances. Due to the nature of the assets in which the Fund intends to invest, the Fund’s taxable income may exceed the Fund’s net income as determined based on generally accepted accounting principles (“GAAP”) because, for example, realized capital losses will be deducted in determining the Fund’s GAAP net income but may not be deductible in computing the Fund’s taxable income required to be distributed. In addition, the Fund may invest in assets, including debt instruments requiring the Fund to accrue OID, that generate taxable income (referred to as “phantom income”) in excess of economic income or in advance of the corresponding cash flow from the assets. In addition, if the debt instruments provide for “payment-in-kind” or “PIK” interest, the Fund may recognize OID for U.S. federal income tax purposes. Moreover, the Fund may acquire distressed debt investments that are subsequently modified by agreement with the borrower. If the amendments to the outstanding debt are “significant modifications” under the applicable Treasury regulations, the modified debt may be considered to have been reissued to the Fund in a debt-for-debt exchange with the borrower. In that event, if the debt is

68

considered to be “publicly traded” for U.S. federal income tax purposes, the modified debt in the hands of the Fund may be considered to have been issued with OID to the extent the fair market value of the modified debt is less than the principal amount of the outstanding debt. Also, certain previously modified debt that the Fund acquires in the secondary market may be considered to have been issued with OID at the time it was modified. In general, the Fund will be required to accrue OID on a debt instrument as taxable income in accordance with applicable U.S. federal income tax rules even though no cash payments may be received on such debt instrument. In the event a borrower with respect to a particular debt instrument encounters financial difficulty rendering it unable to pay stated interest as due, the Fund may nonetheless be required to continue to recognize the unpaid interest as taxable income. Similarly, the Fund may be required to accrue interest income with respect to subordinated MBS at the stated rate regardless of when their corresponding cash payments are received. Further, the Fund may invest in assets that accrue market discount income, which may result in the recognition of taxable income in excess of the Fund’s economic gain in certain situations.

Due to each of these potential timing differences between income recognition or expense deduction and cash receipts or disbursements, there is a significant risk that the Fund may have substantial taxable income in excess of cash available for distribution. To satisfy its distribution requirements, the Fund may borrow on unfavorable terms or distribute amounts that would otherwise be invested in future acquisitions, capital expenditures or repayment of debt. In addition, the Fund may make distributions of its Common Stock to satisfy the distribution requirements necessary to maintain the Fund’s treatment as a regulated investment company for U.S. federal income tax purposes and to avoid U.S. federal income and excise taxes, but no assurances can be given in this regard. Moreover, if the Fund’s only feasible alternative were to make a taxable distribution of the Fund’s Common Stock to comply with the regulated investment company distribution requirements for any taxable year and the value of the Fund’s Common Stock was not sufficient at such time to make a distribution to its Common Stockholders in an amount at least equal to the minimum amount required to comply with such regulated investment company distribution requirements, the Fund would generally fail to qualify for treatment as a regulated investment company for such taxable year.

Despite undertaking the efforts mentioned in the previous paragraph, the Fund may not be able to distribute the amounts necessary to satisfy the distribution requirements necessary to maintain its regulated investment company treatment for U.S. federal income tax purposes and to avoid U.S. federal income and excise taxes. If the Fund were unable to satisfy the 90% distribution requirement or otherwise were to fail to qualify as a regulated investment company in any year, material adverse tax consequences would result to investors. The Fund would be taxed in the same manner as an ordinary corporation and distributions to the Fund’s Common Stockholders would not be deductible by the Fund in computing its taxable income. To qualify again to be taxed as a regulated investment company in a subsequent year, the Fund would be required to distribute to its shareholders its earnings and profits attributable to non-regulated investment company years reduced by an interest charge on 50% of such earnings and profits payable by the Fund to the Internal Revenue Service (“IRS”). In addition, if the Fund failed to qualify as a regulated investment company for a period greater than two taxable years, then the Fund would be required to elect to recognize and pay tax on any net built-in gain (the excess of aggregate gain, including items of income, over aggregate loss that would have been realized if the Fund had been liquidated) or, alternatively, be subject to taxation on such built-in gain recognized for a period of 5 years, in order to qualify as a regulated investment company in a subsequent year.

Cash/Stock Dividend Risks. In certain circumstances, the Fund may make distributions of its Common Stock to satisfy the distribution requirements necessary to maintain its regulated investment company treatment for U.S. federal income tax purposes and to avoid U.S. federal income and excise taxes. Under IRS Revenue Procedure 2017-45, the Fund may distribute taxable dividends that are payable in cash or Common Stock at the election of each Common Stockholder, with up to 80% of the aggregate of any taxable dividends payable in the Fund’s Common Stock and the 20% or greater balance paid in cash. Common Stockholders receiving such dividends will be required to include the full amount of the dividend as taxable income to the extent of the Fund’s current or accumulated earnings and profits for U.S. federal income tax purposes. As a result, Common Stockholders may be required to pay U.S. federal income taxes with respect to such dividends in excess of the

69

cash dividends received. If a Common Stockholder sells the Common Stock that it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of the Fund’s Common Stock at the time of the sale. Furthermore, with respect to non-U.S. Common Stockholders, the Fund may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in Common Stock. In addition, if a significant number of the Fund’s Common Stockholders determine to sell shares of the Fund’s Common Stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of the Fund’s Common Stock. It is unclear whether and to what extent the Fund will be able to pay taxable dividends in cash and Common Stock (whether pursuant to Revenue Procedure 2017-45 or otherwise).

Government Intervention in Financial Markets Risk

United States federal and state governments and foreign governments, their regulatory agencies or self-regulatory organizations may take actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity, that affect the regulation of the securities in which the Fund invests, or the issuers of such securities, in ways that are unforeseeable issuers of corporate fixed income securities might seek protection under the bankruptcy laws. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives. Western Asset monitors developments and seeks to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objective, but there can be no assurance that it will be successful in doing so.

Currency Risks

The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation. The Fund may be unable or may choose not to hedge its foreign currency exposure.

Expedited Transactions

Investment analyses and decisions by FTFA and Western Asset may frequently be required to be undertaken on an expedited basis to take advantage of investment opportunities. In such cases, the information available to FTFA or Western Asset at the time of an investment decision may be limited, and FTFA and Western Asset may not have access to detailed information regarding the investment opportunity. Therefore, no assurance can be given that FTFA or Western Asset will have knowledge of all circumstances that may adversely affect an investment.

Extension Risk

Extension, or slower prepayments of the underlying mortgage loans, would extend the time it would take to receive cash flows and would generally compress the yield on non-agency RMBS and CMBS. Rising interest rates can cause the average maturity of the Fund to lengthen due to a drop in mortgage prepayments. This will increase both the sensitivity to rising interest rates and the potential for price declines of the Fund.

“Widening” Risk

The prices of non-agency RMBS or CMBS may decline substantially, for reasons that may not be attributable to any of the other risks described in this prospectus. In particular, purchasing assets at what may

70

appear to be “undervalued” levels is no guarantee that these assets will not be trading at even more “undervalued” levels at a time of valuation or at the time of sale. It may not be possible to predict, or to protect against, such “spread widening” risk.

Management Risk and Reliance on Key Personnel

The Fund is subject to management risk because it is an actively managed investment portfolio. Western Asset and each individual portfolio manager may not be successful in selecting the best performing securities or investment techniques, and the Fund’s performance may lag behind that of similar funds. The Fund depends upon the diligence and skill of the portfolio managers, who evaluate, negotiate, structure and monitor its investments. These individuals do not have long-term employment contracts with Western Asset, although they do have equity interests and other financial incentives to remain with the Western Asset. The Fund also depends on the senior management of FTFA, and the departure of any of the senior management of FTFA could have a material adverse effect on the Fund’s ability to achieve its investment objectives. In addition, there is no guarantee that the Western Asset will remain our investment adviser.

Credit Crisis Liquidity and Volatility Risk

The markets for credit instruments, including MBS, have experienced periods of extreme illiquidity and volatility. General market uncertainty and consequent repricing risk have led to market imbalances of sellers and buyers, which in turn have resulted in significant valuation uncertainties in a variety of MBS. These conditions resulted, and in many cases continue to result in, greater volatility, less liquidity, widening credit spreads and a lack of price transparency, with many MBS remaining illiquid and of uncertain value. These market conditions may make valuation of some of the Fund’s MBS uncertain and/or result in sudden and significant valuation increases or declines in its holdings. A significant decline in the value of the Fund’s portfolio would likely result in a significant decline in the value of your investment in Common Stock.

The debt and equity capital markets in the United States have been negatively impacted by significant write-offs in the financial services sector relating to subprime mortgages and the re-pricing of credit risk in the broadly syndicated market, among other things. These events, along with the deterioration of the housing market and the failure of major financial institutions, have led to worsening general economic conditions, which have materially and adversely impacted the broader financial and credit markets and have reduced the availability of debt and equity capital for the market as a whole and financial firms in particular. These developments may increase the volatility of the value of securities owned by the Fund and also may make it more difficult for the Fund to accurately value securities or to sell securities on a timely basis. These developments have adversely affected the broader economy, and may continue to do so, which in turn may adversely affect the ability of issuers of securities owned by the Fund to make payments of principal and interest when due, lead to lower credit ratings and increase defaults. Such developments could, in turn, reduce the value of securities owned by the Fund and adversely affect the net asset value of the Fund. In addition, the prolonged continuation or further deterioration of current market conditions could adversely impact the Fund’s portfolio.

Investment Focus

The Fund invests a substantial portion of its assets in MBS and mortgage whole loans. As a result, the Fund will be affected to a greater degree by events affecting the MBS and mortgage whole loan markets, than if it invested in a broader array of securities, and such impact could be considerably greater than if it did not focus its investments to such an extent, particularly as a result of the leveraged nature of its investments. Such restrictions on the type of securities in which the Fund may invest may adversely affect the Fund’s ability to achieve its investment objectives.

The Fund employs a variety of proprietary risk analytics and risk management tools in connection with making and monitoring portfolio investments. Prospective investors should be aware that no risk management or

71

portfolio analytics system is fail-safe, and no assurance can be given that risk frameworks employed by either FTFA and/or Western Asset (e.g., stop-win, stop-loss, Sharpe Ratios, loss limits, value-at-risk or any other methodology now known or later developed) will achieve their objectives and prevent or otherwise limit substantial losses. No assurance can be given that the risk management systems and techniques or pricing models will accurately predict future trading patterns or the manner in which investments are priced in financial markets in the future. In addition, certain risk management tools may rely on certain assumptions (e.g., historical interest rates, anticipated rate trends) and such assumptions may prove incorrect.

Competition for Investment Opportunities

Identifying, completing and realizing attractive portfolio investments is competitive and involves a high degree of uncertainty. The Fund’s profitability depends, in large part, on its ability to acquire target assets at attractive prices. In acquiring its target assets, the Fund will compete with a variety of institutional investors, including specialty finance companies, public and private funds (including other funds managed by FTFA or Western Asset), commercial and investment banks, commercial finance and insurance companies and other financial institutions. Many of the Fund’s competitors are substantially larger and have considerably greater financial, technical, marketing and other resources than does the Fund. Some competitors may have a lower cost of funds and access to funding sources that may not be available to the Fund, such as funding from the U.S. government, if the Fund is not eligible to participate in certain programs established by the U.S. government. In addition, some of the Fund’s competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than the Fund. Furthermore, competition for investments in the Fund’s target assets may lead to the price of such assets increasing, which may further limit the Fund’s ability to generate desired returns. The Fund cannot assure you that the competitive pressures it faces will not have a material adverse effect on its business, financial condition and results of operations. Also, as a result of this competition, desirable investments in the Fund’s target assets may be limited in the future and the Fund may not be able to take advantage of attractive investment opportunities from time to time, as the Fund can provide no assurance that it will be able to identify and make investments that are consistent with its investment objectives. Additional third-party managed investment funds with similar objectives may be formed in the future. Given the foregoing, it is possible that competition for appropriate portfolio investments may increase, thus reducing the number of attractive portfolio investment opportunities available to the Fund and may adversely affect the terms upon which investments can be made. There can be no assurance that the Fund will be able to locate, consummate and exit investments that satisfy its investment objective, or that it will be able to invest the net proceeds from this offering in MBS to the extent necessary to achieve its investment objectives.

Inflation/Deflation Risk

Inflation risk is the risk that the value of certain assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Stock and distributions on the Common Stock can decline. In addition, during any periods of rising inflation, the dividend rates or borrowing costs associated with the Fund’s use of leverage would likely increase, which would tend to further reduce returns to stockholders. Deflation risk is the risk that prices throughout the economy decline over time—the opposite of inflation. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio.

Reinvestment Risk

Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the market price of Common Stock or your overall returns.

72

Reverse Repurchase Agreements Risk

The Fund’s use of reverse repurchase agreements involves many of the same risks involved in the Fund’s use of leverage, as the proceeds from reverse repurchase agreements generally will be invested in additional securities. There is a risk that the market value of the securities acquired in the reverse repurchase agreement may decline below the price of the securities that the Fund has sold but remains obligated to repurchase. In addition, there is a risk that the market value of the securities retained by the Fund may decline. If the buyer of securities under a reverse repurchase agreement were to file for bankruptcy or experience insolvency, the Fund may be adversely affected. Also, in entering into reverse repurchase agreements, the Fund would bear the risk of loss to the extent that the proceeds of the reverse repurchase agreement are less than the value of the underlying securities. In addition, due to the interest costs associated with reverse repurchase agreements transactions, the Fund’s net asset value will decline, and, in some cases, the Fund may be worse off than if it had not used such instruments.

Repurchase Agreements Risk

Subject to its investment objectives and policies, the Fund may invest in repurchase agreements for investment purposes. Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. The Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses, including (1) possible decline in the value of the underlying security during the period in which the Fund seeks to enforce its rights thereto; (2) possible lack of access to income on the underlying security during this period; and (3) expenses of enforcing its rights. While repurchase agreements involve certain risks not associated with direct investments in debt securities, the Fund follows procedures approved by the Fund’s Board of Directors that are designed to minimize such risks. These procedures include effecting repurchase transactions only with large, well-capitalized and well-established financial institutions whose financial condition will be continually monitored by Western Asset. In addition, as described above, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund generally will seek to liquidate such collateral. However, the exercise of the Fund’s right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss.

Variable Debt Risk

The absence of an active secondary market with respect to particular variable and floating rate instruments could make it difficult for the Fund to dispose of a variable or floating rate note if the issuer defaulted on its payment obligation or during periods that the Fund is not entitled to exercise its demand rights, and the Fund could, for these or other reasons, suffer a loss with respect to such instruments.

Credit Default Swap Risk

The Fund may invest in credit default swap transactions for hedging or investment purposes. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risk. The “buyer” in a credit default contract is obligated to pay the “seller” a periodic stream of payments over the term of the contract, provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or “par value,” of the reference obligation through either physical settlement or cash settlement. The Fund may be either the buyer or seller in a

73

credit default swap transaction. If the Fund is a buyer and no event of default occurs, the Fund will have made a series of periodic payments and recover nothing of monetary value. However, if an event of default occurs, the Fund (if the buyer) will receive the full notional value of the reference obligation either through a cash payment in exchange for the asset or a cash payment in addition to owning the reference assets. As a seller, the Fund receives a fixed rate of income throughout the term of the contract, which typically is between six months and five years, provided that there is no event of default. The Fund currently intends to segregate assets on the Fund’s records in the form of cash, cash equivalents or liquid securities in an amount equal to the notional value of the credit default swaps of which it is the seller. If such assets are not fully segregated by the Fund, the use of credit default swap transactions could then be considered leverage for purposes of the 1940 Act and the Fund’s limits on leverage. Credit default swap transactions involve greater risks than if the Fund had invested in the reference obligation directly.

Structured Notes and Related Instruments Risk

The Fund may invest in “structured” notes and other related instruments, which are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets, such as indexes reflecting bonds. Structured instruments may be issued by corporations, including banks, as well as by governmental agencies. Structured instruments frequently are assembled in the form of medium-term notes, but a variety of forms are available and may be used in particular circumstances. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but ordinarily not below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending on a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index(es) or other asset(s). Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Insolvency Considerations with Respect to Issuers of Indebtedness

Various laws enacted for the protection of U.S. creditors may apply to MBS in which the Fund invests. If a court in a lawsuit brought by an unpaid creditor or representative of the creditors of an issuer of MBS, such as a trustee in bankruptcy, were to find that the issuer did not receive fair consideration or reasonably equivalent value for incurring the indebtedness, and after giving effect to such indebtedness, the issuer (i) was insolvent, (ii) was engaged in a business for which the remaining assets of such issuer constituted unreasonably small capital or (iii) intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature, such court could determine to invalidate, in whole or in part, such indebtedness as a fraudulent conveyance, to subordinate such indebtedness to existing or future creditors of such issuer, or to recover amounts previously paid by such issuer in satisfaction of such indebtedness. The measure of insolvency for purposes of the foregoing will vary. Generally, an issuer would be considered insolvent at a particular time if the sum of its debts were then greater than all of its property at a fair valuation, or if the present fair saleable value of its assets was then less than the amount that would be required to pay its probable liabilities on its existing debts as they became absolute and matured. There can be no assurance as to what standard a court would apply in order to determine whether the issuer was “insolvent” after giving effect to the incurrence of the indebtedness in which the Fund invested or that, regardless of the method of valuation, a court would not determine that the issuer was “insolvent” upon giving effect to such incurrence. In addition, in the event of the insolvency of an issuer of indebtedness in which the Fund invests, payments made on such indebtedness could be subject to avoidance as a “preference” if made within a certain period of time (which may be as long as one year) before insolvency. In general, if payments on indebtedness are avoidable, whether as fraudulent conveyances or preferences, such payments can be recaptured from the Fund.

74

Portfolio Valuation for Financial Accounting and Other Reporting Purposes

Valuations of the portfolio investments may involve uncertainties and judgment determinations. Third-party pricing information can vary considerably from one dealer or pricing service to another, and may at times not be available regarding certain of the investments of the Fund. A disruption in the secondary markets for the investments of the Fund may make it difficult to obtain accurate market quotations for purposes of valuing portfolio investments for financial accounting, borrowing and other reporting purposes. Further, because of the overall size and concentrations in particular markets and maturities of positions that may be held by the Fund from time to time, the liquidation values of portfolio investments may differ significantly from the valuations of such portfolio investments derived from the valuation methods described herein.

Some of the Fund’s portfolio investments will be in the form of securities that are not publicly traded. The fair value of securities and other investments that are not publicly traded may not be readily determinable. The Fund will value these investments daily at fair value, as determined in accordance with FASB ASC 820, “Fair Value Measurements,” which may include unobservable inputs. Because such valuations are subjective, the fair value of certain of the Fund’s assets may fluctuate over short periods of time and the Fund’s determinations of fair value may differ materially from the values that would have been used if a ready market for these securities existed. The value of the Fund’s Common Stock could be adversely affected if the Fund’s determinations regarding the fair value of these investments were materially higher than the values that it ultimately realizes upon their disposal.

Inverse Floating Rate Securities and Tender Option Bonds Risk

Subject to certain limitations, the Fund may invest in inverse floating rate securities. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a “tender option bond trust”) formed by a third party sponsor for the purpose of holding MBS purchased from the Fund or from another third party. An investment in an inverse floating rate security may involve greater risk than an investment in a fixed-rate bond. Because changes in the interest rate on the underlying security or index inversely affect the residual interest paid on the inverse floating rate security, the value of an inverse floating rate security is generally more volatile than that of a fixed-rate bond.

Inverse floating rate securities have interest rate adjustment formulas which generally reduce or, in the extreme, eliminate the interest paid to the Fund when short-term interest rates rise, and increase the interest paid to the Fund when short-term interest rates fall. Inverse floating rate securities have varying degrees of liquidity, and the market for these securities is relatively volatile. These securities tend to underperform the market for fixed-rate bonds in a rising interest rate environment, but tend to outperform the market for fixed-rate bonds when interest rates decline. Shifts in long-term interest rates may, however, alter this tendency.

During times of reduced market liquidity, such as at the present, the Fund may not be able to sell MBS readily at prices reflecting the values at which the securities are carried on the Fund’s books. Sales of large blocks of MBS by market participants, such as the Fund, that are seeking liquidity can further reduce MBS prices in an illiquid market. The Fund may seek to make sales of large blocks of MBS as part of its investment strategy or it may be required to raise cash to re-collateralize, unwind or “collapse” tender option bond trusts that issued inverse floating rate securities to the Fund or to make payments to such trusts to enable them to pay for tenders of the short-term securities they have issued if the remarketing agents for those MBS are unable to sell the short-term securities in the marketplace to other buyers. The Fund’s potential exposure to losses related to or on inverse floating rate securities may increase beyond the value of the Fund’s inverse floater investments as the Fund may potentially be liable to fulfill all amounts owed to holders of the floating rate certificates.

Although volatile, inverse floating rate securities typically offer the potential for yields exceeding the yields available on fixed-rate bonds with comparable credit quality, coupon, call provisions and maturity. These securities usually permit the investor to convert the floating rate to a fixed rate (normally adjusted downward), and this optional conversion feature may provide a partial hedge against rising rates if exercised at an opportune time.

75

Investment in inverse floating rate securities may amplify the effects of the Fund’s use of leverage. Any economic effect of leverage through the Fund’s purchase of inverse floating rate securities will create an opportunity for increased Common Stock net income and returns, but may also result in losses if the cost of leverage exceeds the value of the securities underlying the tender option bond trust or the return on the inverse floating rate securities purchased by the Fund.

Other Investment Companies Risk

The Fund may invest in the securities of other investment companies. Such securities may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. Utilization of leverage is a speculative investment technique and involves certain risks. An investment in securities of other investment companies that are leveraged may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the Common Stock) will be diminished.

Risks Related to Fund Distributions

Limited liquidity in the MBS market may affect the market price of MBS securities, thereby adversely affecting the net asset values of the Fund and its ability to make dividend distributions.

Derivatives Risk

The Fund may invest in derivative instruments, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit linked notes, credit default swaps and other swap agreements for investment, hedging and risk management purposes; provided that the Fund’s use of derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its Managed Assets. With respect to this limitation, the Fund may net derivatives with opposite exposure to the same underlying instrument. Notwithstanding the foregoing, the Fund may invest without limitation in Treasury futures, Eurodollar futures, interest rate swaps, swaptions or similar instruments and combinations thereof. Using derivatives can increase Fund losses and reduce opportunities for gains when market prices, interest rates, currencies, or the derivatives themselves behave in a way not anticipated by the Fund. Using derivatives also can have a leveraging effect and increase Fund volatility. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivatives may not be available at the time or price desired, may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Fund. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. The value of a derivative may fluctuate more than the underlying assets, rates, indices or other indicators to which it relates. Use of derivatives may have different tax consequences for the Fund than an investment in the underlying security, and those differences may affect the amount, timing and character of income distributed to shareholders. The U.S. government and foreign governments are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.

Effective August 19, 2022, the Fund began operating under Rule 18f-4 under the 1940 Act which, among other things, governs the use of derivative investments and certain financing transactions (e.g. reverse repurchase agreements) by registered investment companies. Among other things, Rule 18f-4 requires funds that invest in derivative instruments beyond a specified limited amount to apply a value at risk (VaR) based limit to their use of certain derivative instruments and financing transactions and to adopt and implement a derivatives risk management program. A fund that uses derivative instruments in a limited amount is not subject to the full requirements of Rule 18f-4. Compliance with Rule 18f-4 by the Fund could, among other things, make derivatives more costly, limit their availability or utility, or otherwise adversely affect their performance. Rule 18f-4 may limit the Fund’s ability to use derivatives as part of its investment strategy.

76

Credit default swap contracts involve heightened risks and may result in losses to the Fund. Credit default swaps may be illiquid and difficult to value. When the Fund sells credit protection via a credit default swap, credit risk increases since the Fund has exposure to both the issuer whose credit is the subject of the swap and the counterparty to the swap.

Short Sales Risk

To the extent the Fund makes use of short sales for investment and/or risk management purposes, the Fund may be subject to risks associated with selling short. Short sales are transactions in which the Fund sells securities or other instruments that the Fund does not own. Short sales expose the Fund to the risk that it will be required to cover its short position at a time when the securities have appreciated in value, thus resulting in a loss to the Fund. The Fund may engage in short sales where it does not own or have the right to acquire the security sold short at no additional cost. The Fund’s loss on a short sale theoretically could be unlimited in a case where the Fund is unable, for whatever reason, to close out its short position. In addition, the Fund’s short selling strategies may limit its ability to benefit from increases in the markets. If the Fund engages in short sales, it will segregate liquid assets, enter into offsetting transactions or own positions covering its obligations; however, such segregation and cover requirements will not limit or offset losses on related positions. Short selling also involves a form of financial leverage that may exaggerate any losses realized by the Fund. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund. The Fund will incur transaction costs with any short sales, which will be borne by shareholders. Finally, regulations imposed by the SEC or other regulatory bodies relating to short selling may restrict the Fund’s ability to engage in short selling.

The Fund’s obligation to replace a borrowed security is secured by collateral deposited with the broker-dealer, usually cash, U.S. government securities or other liquid securities similar to those borrowed. The Fund is also required to segregate similar collateral to the extent, if any, necessary so that the value of both collateral amounts in the aggregate is at all times equal to at least 100% of the current market value of the security sold short. Depending on arrangements made with the broker-dealer from which the Fund borrowed the security regarding payment over of any payments received by us on such security, the Fund may not receive any payments (including interest) on the collateral deposited with such broker-dealer.

Risks of Short Economic Exposure Through Derivatives

The use by the Fund of derivatives such as options, forwards or futures contracts for investment and/or risk management purposes may subject the Fund to risks associated with short economic exposure through such derivatives. Taking a short economic position through derivatives exposes the Fund to the risk that it will be obligated to make payments to its counterparty if the underlying asset appreciates in value, thus resulting in a loss to the Fund. The Fund’s loss on a short position using derivatives theoretically could be unlimited.

Risks of Futures and Options on Futures

The use by the Fund of futures contracts and options on futures contracts to hedge interest rate risks involves special considerations and risks, as described below.

77

Liquidity Risk

The Fund may invest in MBS, for which there is no readily available trading market or which are otherwise illiquid. Liquidity risk exists when particular investments are difficult to sell. Securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the portfolio may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments for cash needs, the Fund may suffer a loss.

When-Issued and Delayed-Delivery Transactions Risk

The Fund may purchase fixed income securities on a when-issued basis, and may purchase or sell those securities for delayed delivery. When-issued and delayed-delivery transactions occur when securities are purchased or sold by the Fund with payment and delivery taking place in the future to secure an advantageous yield or price. Securities purchased on a when-issued or delayed-delivery basis may expose the Fund to counterparty risk of default as well as the risk that securities may experience fluctuations in value prior to their actual delivery. The Fund will not accrue income with respect to a when-issued or delayed-delivery security prior to its stated delivery date. Purchasing securities on a when-issued or delayed-delivery basis can involve the additional risk that the price or yield available in the market when the delivery takes place may not be as favorable as that obtained in the transaction itself.

Non-Diversification Risk

The Fund is classified as “non-diversified” under the 1940 Act. As a result, it can invest a greater portion of its assets in obligations of a single issuer than a “diversified” fund. The Fund may therefore be more susceptible than a diversified fund to being adversely affected by any single corporate, economic, political or regulatory occurrence. The Fund intends to qualify for the special tax treatment available to “regulated investment companies” under Subchapter M of the Code, and thus intends to satisfy the diversification requirements of Subchapter M, including the less stringent diversification requirement that applies to the percent of its total assets that are represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and certain other securities.

Risks Related to Potential Conflicts of Interest

FTFA, Western Asset and the portfolio managers have interests which may conflict with the interests of the Fund. FTFA and Western Asset may at some time in the future manage and/or advise other investment funds or accounts with the same or substantially similar investment objective and strategies as the Fund. As a result, FTFA, Western Asset and the Fund’s portfolio managers may devote unequal time and attention to the management of the Fund and those other funds and accounts, and may not be able to formulate as complete a

78

strategy or identify equally attractive investment opportunities as might be the case if they were to devote substantially more attention to the management of the Fund. FTFA, Western Asset and the Fund’s portfolio managers may identify a limited investment opportunity that may be suitable for multiple funds and accounts, and the opportunity may be allocated among these several funds and accounts, which may limit the Fund’s ability to take full advantage of the investment opportunity. Additionally, transaction orders may be aggregated for multiple accounts for purpose of execution, which may cause the price or brokerage costs to be less favorable to the Fund than if similar transactions were not being executed concurrently for other accounts. At times, a portfolio manager may determine that an investment opportunity may be appropriate for only some of the funds and accounts for which he or she exercises investment responsibility, or may decide that certain of the funds and accounts should take differing positions with respect to a particular security. In these cases, the portfolio manager may place separate transactions for one or more funds or accounts which may affect the market price of the security or the execution of the transaction, or both, to the detriment or benefit of one or more other funds and accounts. For example, a portfolio manager may determine that it would be in the interest of another account to sell a security that the Fund holds, potentially resulting in a decrease in the market value of the security held by the Fund.

The portfolio managers may also engage in cross trades between funds and accounts, may select brokers or dealers to execute securities transactions based in part on brokerage and research services provided to FTFA or Western Asset which may not benefit all funds and accounts equally and may receive different amounts of financial or other benefits for managing different funds and accounts. Finally, FTFA or its affiliates may provide more services to some types of funds and accounts than others.

There is no guarantee that the policies and procedures adopted by FTFA, Western Asset and the Fund will be able to identify or mitigate the conflicts of interest that arise between the Fund and any other investment funds or accounts that FTFA and/or Western Asset may manage or advise from time to time.

Counterparty Risk

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts (whether a clearing corporation in the case of exchange-traded instruments or another party in the case of over-the-counter instruments) and other instruments entered into directly by the Fund or held by special purpose or structured vehicles in which the Fund invests. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties or otherwise, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy, or other analogous proceeding. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative transaction would typically be terminated at its fair market value. If the Fund is owed this fair market value in the termination of the derivative transaction and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty, and will not have any claim with respect to the underlying reference asset or security. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

Counterparty risk with respect to certain exchange-traded and over-the-counter derivatives may be further complicated by U.S. financial reform legislation.

Portfolio Turnover Risk

The Fund’s annual portfolio turnover rate may vary greatly from year to year. Changes to the investments of the Fund may be made regardless of the length of time particular investments have been held. A high portfolio turnover rate may result in increased transaction costs for the Fund in the form of increased dealer spreads and other transactional costs, which may have an adverse impact on the Fund’s performance. In addition, high portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when

79

distributed to stockholders, will be taxable as ordinary income. A high portfolio turnover may increase the Fund’s current and accumulated earnings and profits, resulting in a greater portion of the Fund’s distributions being treated as a dividend to the Fund’s stockholders. The portfolio turnover rate of the Fund will vary from year to year, as well as within a given year.

Temporary Defensive Strategies Risk

When Western Asset anticipates unusual market or other conditions, the Fund may temporarily depart from its principal investment strategies as a defensive measure and invest all or a portion of its assets non-U.S. government securities which have received the highest investment grade credit rating and U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the Treasury or by U.S. government agencies or instrumentalities; certificates of deposit issued against funds deposited in a bank or a savings and loan association; commercial paper; bankers’ acceptances; bank time deposits; shares of money market funds; repurchase agreements with respect to any of the foregoing; or any other fixed income securities that Western Asset considers consistent with this strategy. To the extent that the Fund invests defensively, it may not achieve its investment objectives.

Anti-Takeover Provisions Risk.

The Fund’s Charter and Bylaws include provisions that are designed to limit the ability of other entities or persons to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund’s ability to achieve its primary investment objective of seeking high current income. The Bylaws also contain a provision providing that the Board of Directors has adopted a resolution to opt in the Fund to the provisions of the MCSAA. There can be no assurance, however, that the provisions of the MCSAA will be sufficient to deter professional arbitrageurs that seek to cause the Fund to take actions that may not be consistent with its investment objective or aligned with the interests of long-term shareholders, such as liquidating debt investments prior to maturity, triggering taxable events for shareholders and decreasing the size of the Fund. See “Certain Provisions in the Charter and Bylaws” and “Certain Provisions in the Charter and Bylaws—Maryland Control Share Acquisition Act” (“MCSAA”). Such provisions may limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging an investor from seeking to obtain control of the Fund. There can be no assurance, however, that such provisions will be sufficient to deter professional investors that seek to cause the Fund to take actions that may not be aligned with the interests of long-term shareholders in order to allow the professional investor to arbitrage the Fund’s market price. See “Certain Provisions in the Charter and Bylaws” and “Certain Provisions in the Charter and Bylaws—Maryland Control Share Acquisition Act.”

In determining to opt in to the MCSAA, the Board of Directors considered its fiduciary obligations to the Fund. In particular, the Board of Directors considered whether the interests of a short-term professional investor seeking to arbitrage the Fund’s market price would be consistent with the interests of shareholders that invested in the Fund due to its investment objective of seeking high current income. In order to seek to allow the Fund to achieve its investment objective for those long-term shareholders, the Board of Directors determined that it would be in the best interests of the Fund to opt in to the MCSAA. In making this decision, the Board of Directors considered a decision in the U.S. District Court for the District of Maryland, which had the effect of allowing a closed-end fund organized in Maryland to remain opted in to the MCSAA notwithstanding a counterclaim alleging that the fund’s decision to opt in to the MCSAA violated Section 18(i) of the 1940 Act. A recent decision by the U.S. District Court for the Southern District of New York, however, held that certain Funds that opted into the MCSAA violated Section 18(i) of the 1940 Act. The decision has been affirmed by the U.S. Court of Appeals for the Second Circuit. These decisions are incompatible with the prior decision in Maryland federal court that allowed a registered closed-end fund organized as a Maryland corporation to remain opted into the MCSAA, resulting in a circuit split on the issue. There is a risk that a court could follow the reasoning of the New York federal court, as opposed to the decision of the Maryland federal court, when determining whether a closed-end fund organized in Maryland can opt in to the MCSAA.

80

Market Events Risk

The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to factors such as economic events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, the global and domestic effects of widespread or local health, weather or climate events, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, wars, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries or markets directly affected, the value and liquidity of the fund’s investments may be negatively affected. Following Russia’s invasion of Ukraine, Russian stocks lost all, or nearly all, of their market value. Other securities or markets could be similarly affected by past or future geopolitical or other events or conditions. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the fund’s investments.

The long-term impact of the COVID-19 pandemic and its subsequent variants on economies, markets, industries and individual issuers is not known. Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets, reduced liquidity of many instruments, increased government debt, inflation, and disruptions to supply chains, consumer demand and employee availability, may continue for some time. The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, took extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic. This and other government intervention into the economy and financial markets may not work as intended, and have resulted in a large expansion of government deficits and debt, the long term consequences of which are not known. In addition, the COVID-19 pandemic, and measures taken to mitigate its effects, could result in disruptions to the services provided to the fund by its service providers.

Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. Recently, inflation and interest rates have increased and may rise further. These circumstances could adversely affect the value and liquidity of the fund’s investments, impair the fund’s ability to satisfy redemption requests, and negatively impact the fund’s performance.

The United States and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the United States has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the United States and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The United States government has prohibited U.S. persons from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the fund’s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the fund’s assets may go down.

81

Managed Distribution Risk

Under a managed distribution policy, the Fund would intend to make monthly distributions to stockholders at a fixed rate per share of Common Stock or a fixed percentage of net asset value that may include periodic distributions of long-term capital gains. Under a managed distribution policy, if, for any monthly distribution, ordinary income (that is, net investment income and any net short-term capital gain) and net realized capital gains were less than the amount of the distribution, the difference would be distributed from the Fund’s previously accumulated earnings and profits or cash generated from the sale of Fund assets. If, for any fiscal year, the total distributions exceeded ordinary income and net realized capital gains (the “Excess”), the Excess would decrease the Fund’s total assets and, as a result, would have the likely effect of increasing the Fund’s expense ratio. There is a risk that the Fund would not eventually realize capital gains in an amount corresponding to a distribution of the Excess. In addition, in order to make such distributions, the Fund may have to sell a portion of its investment portfolio at a time when independent investment judgment might not dictate such action. If the Fund were to issue senior securities and not be in compliance with the asset coverage requirements of the 1940 Act, the Fund would be required to suspend the managed distribution policy. Pursuant to the requirements of the 1940 Act and other applicable laws, a notice will accompany each monthly distribution disclosing the sources of the distribution.

Personnel Turnover Risk

As a result of current deteriorating market conditions or other reasons, FTFA and Western Asset may need to implement cost reductions in the future which could make the retention of qualified and experienced personnel more difficult and could lead to personnel turnover. Loss of significant personnel, whether in terms of number or role in managing the Fund or an inability to hire qualified replacements in a timely manner, could adversely affect the operation of the Fund and its ability to achieve its investment objectives and pursue its anticipated strategies.

Dilution Risk

The voting power of current Common Stockholders of the Fund will be diluted to the extent that such current Common Stockholders do not purchase Common Stock in any future offerings of Common Stock or do not purchase sufficient Common Stock to maintain their percentage interest. If the Fund is unable to invest the proceeds of such offerings as intended, the Fund’s per share distributions may decrease and the Fund may not participate in market advances to the same extent as if such proceeds were fully invested as planned.

Legal and Regulatory Risk

Legal, tax and regulatory changes could occur and may adversely affect the Fund and its ability to pursue its investment strategies and/or increase the costs of implementing such strategies. New (or revised) laws or regulations may be imposed by the CFTC, the SEC, the U.S. Federal Reserve or other banking regulators, other governmental regulatory authorities or self-regulatory organizations that supervise the financial markets that could adversely affect the Fund. In particular, these agencies are empowered to promulgate a variety of new rules pursuant to recently enacted financial reform legislation in the United States. The Fund also may be adversely affected by changes in the enforcement or interpretation of existing statutes and rules by these governmental regulatory authorities or self-regulatory organizations.

In addition, the securities and futures markets are subject to comprehensive statutes, regulations and margin requirements. The CFTC, the SEC, the Federal Deposit Insurance Corporation, other regulators and self-regulatory organizations and exchanges are authorized under these statutes, regulations and otherwise to take extraordinary actions in the event of market emergencies. The Fund and the Investment Manager have historically been eligible for exemptions from certain regulations. However, there is no assurance that the Fund and FTFA will continue to be eligible for such exemptions.

82

The U.S. Government enacted legislation that provides for new regulation of the derivatives market, including clearing, margin, reporting, recordkeeping, and registration requirements. Although the CFTC has released final rules relating to clearing, reporting, recordkeeping and registration requirements under the legislation, certain of the provisions are subject to further final rule making, and thus its ultimate impact remains unclear. New regulations could, among other things, restrict the Fund’s ability to engage in derivatives transactions (for example, by making certain types of derivatives transactions no longer available to the Fund) and/or increase the costs of such derivatives transactions (for example, by increasing margin or capital requirements), and the Fund may be unable to execute its investment strategies as a result. It is unclear how the regulatory changes will affect counterparty risk.

The CFTC and certain futures exchanges have established limits, referred to as “position limits,” on the maximum net long or net short positions which any person may hold or control in particular options and futures contracts; those position limits may also apply to certain other derivatives positions the Fund may wish to take. All positions owned or controlled by the same person or entity, even if in different accounts, may be aggregated for purposes of determining whether the applicable position limits have been exceeded. Thus, even if the Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Investment Manager and its affiliates may be aggregated for this purpose. Therefore it is possible that the trading decisions of the Investment Manager may have to be modified and that positions held by the Fund may have to be liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the performance of the Fund.

The SEC has in the past adopted interim rules requiring reporting of all short positions above a certain de minimis threshold and may adopt rules requiring monthly public disclosure in the future. In addition, other non-U.S. jurisdictions where the Fund may trade have adopted reporting requirements. To the extent that the Fund takes a short position, if such short position or strategy become generally known, it could have a significant effect on the Fund’s ability to implement its investment strategy. In particular, it would make it more likely that other investors could cause a “short squeeze” in the securities held short by the Fund forcing the Fund to cover its positions at a loss. Such reporting requirements also may limit the Investment Manager’s ability to access management and other personnel at certain companies where the Fund seeks to take a short position. In addition, if other investors engage in copycat behavior by taking positions in the same issuers as the Fund, the cost of borrowing securities to sell short could increase drastically and the availability of such securities to the Fund could decrease drastically. Such events could make the Fund unable to execute its investment strategy. In addition, the SEC and other regulatory and self-regulatory authorities have implemented various rules and may adopt additional rules in the future that may impact those engaging in short selling activity. If additional rules were adopted regarding short sales, they could restrict the Fund’s ability to engage in short sales in certain circumstances, and the Fund may be unable to execute certain investment strategies as a result.

The SEC and regulatory authorities in other jurisdictions may adopt (and in certain cases, have adopted) bans on short sales of certain securities in response to market events. Bans on short selling may make it impossible for the Fund to execute certain investment strategies.

LIBOR Risk

The Fund’s investments, payment obligations, and financing terms may be based on floating rates, such as the London Interbank Offered Rate, or “LIBOR,” which was the offered rate for short-term Eurodollar deposits between major international banks. In 2017, the U.K. Financial Conduct Authority (“FCA”) announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies. In March 2022, the U.S. federal government enacted legislation to establish a process for replacing LIBOR in certain existing contracts that do not already provide for the use of a clearly defined or practicable replacement benchmark rate as described in the legislation. Generally speaking, for

83

contracts that do not contain a fallback provision as described in the legislation, a benchmark replacement recommended by the Federal Reserve Board effectively automatically replaced the USD LIBOR benchmark in the contract upon LIBOR’s cessation at the end of June 2023. The recommended benchmark replacement is based on the Secured Overnight Financing Rate (SOFR) published by the Federal Reserve Bank of New York, including certain spread adjustments and benchmark replacement conforming changes. Various financial industry groups have been planning for the transition away from LIBOR, but there remains uncertainty regarding the impact of the transition from LIBOR on the Fund’s transactions and the financial markets generally. The transition away from LIBOR may lead to increased volatility and illiquidity in markets that rely on LIBOR and may adversely affect the Fund’s performance. The transition may also result in a reduction in the value of certain LIBOR-based investments held by the Fund or reduce the effectiveness of related transactions such as hedges. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses for the Fund.

Valuation Risk

The sales price the Fund could receive for any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for the securities that trade in thin or volatile markets or that are valued using a fair value methodology.

Operational Risk

The valuation of the Fund’s investments may be negatively impacted because of the operational risks arising from factors such as processing errors and human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third party service providers or trading counterparties. It is not possible to identify all of the operational risks that may affect the Fund or to develop processes and controls that completely eliminate or mitigate the occurrence of such failures. The Fund and its shareholders could be negatively impacted as a result.

These differences may increase significantly and affect Fund investments more broadly during periods of market volatility. The Fund’s ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of the Fund’s investments involves subjective judgment.

Cybersecurity Risk

Like other funds and business enterprises, the fund, the manager, the subadvisers and their service providers are subject to the risk of cyber incidents occuring from time to time. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or proprietary information, cause the Fund, the Fund’s manager and subadvisers and/or their service providers to suffer data breaches, data corruption or loss of operational functionality or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund, manager and subadvisers have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Subadviser Philosophy

In recent years, adverse changes in financial market conditions have required a deleveraging of the entire global financial system and caused the forced sale of large quantities of mortgage-related and other financial assets, resulting in a significant contraction in market liquidity for mortgages and mortgage-related assets. This illiquidity has negatively affected both the terms and availability of financing for most mortgage-related assets, including non-agency RMBS and CMBS, and has generally resulted in mortgage-related assets trading at significantly lower prices compared to prior periods. The recent period has also been characterized by an almost across the board downward movement in non-agency RMBS, CMBS and ABS valuations and correspondingly higher yields to compensate investors for the higher risks associated with owning these assets. The Fund believes that the current distressed conditions in the financial markets present attractive investment opportunities.

Western Asset’s objective for fixed income management is to provide clients with diversified, tightly controlled, value-oriented portfolios. Western Asset’s management style emphasizes the use of multiple strategies and active sector rotation and issue selection. This philosophy is implemented through uniform application of the following key strategic points:

Integrated Team Approach

Western Asset’s fixed income discipline emphasizes a team approach that unites groups of specialists dedicated to different market sectors. A team of investment professionals at Western Asset has daily responsibility for the management of the portfolio and for the implementation of the investment process. The investment responsibilities of each sector group are distinct, yet results are derived from the constant interaction that unites the specialty groups into a cohesive investment management team. The sector teams are comprised of Western Asset’s senior portfolio managers, research analysts, and an in-house economist who are highly skilled and experienced in all major areas of the fixed income market. They exchange views on a daily basis and meet more formally twice each month to review Western Asset’s economic outlook and investment strategy. This structure seeks to ensure that client portfolios benefit from a consensus that draws on the expertise of all team members.

Subadviser Investment Process

The strategic goal at Western Asset is to add value to client portfolios while adhering to a disciplined risk control process. The portfolio construction process begins with Western Asset’s view regarding the global macroeconomic environment as determined by the firm’s senior portfolio managers. The Fund’s investment management team, who have daily responsibility for the management of the portfolio, exercise their investment discretion with the benefit of this macroeconomic viewpoint. Western Asset’s investment philosophy combines traditional analysis with innovative technology applied to all sectors of the market. Western Asset believes inefficiencies exist in the fixed income markets and attempts to add incremental value by exploiting these inefficiencies across all eligible market sectors. Western Asset’s non-agency MBS and CMBS investment processes are described below.

A key element of the non-agency RMBS investment process is the forecast of expected losses due to defaults on the underlying non-agency RMBS loan collateral. The level of losses is dependent on the quantity of loans which default and the loss severity upon liquidation of defaulted loans. Western Asset has developed a number of proprietary tools to analyze residential mortgage loan defaults and loss severities that combine loan

88

level characteristics with zip-code level data, such as unemployment rates, and growth rates for incomes, house prices, populations, and housing supply, to project home price levels and loan and security performance. These tools encompass home price models, default models, and loan loss severity models. When projecting future performance, many assumptions have to be made. Western Asset uses in-house quantitative research from loan level data to project mortgage pool cash flows, analyze security structures, and ultimately assess the risk in its RMBS positions. Western Asset also makes qualitative adjustments to reflect the current state of the housing market, securities market liquidity, and potential implications of policy changes and macroeconomic conditions.

Western Asset’s CMBS investment process is enhanced and supported by proprietary performance models that combine property level data with commercial real estate market factors, including metropolitan specific economic growth rates, property lease trends and property usage trends, to project loan and security performance. Western Asset invests across the capital structure in large diverse conduit deals, single borrower and single property deals as well one-off deals such as credit tenant lease transactions. The level of analysis for different securities will vary based on the risk profile of the investment being evaluated. To manage risk appropriately for troubled CMBS, Western Asset evaluates the potential for losses based on both the structure of the security or loan, as well as how the cash flows and values of the underlying properties will contribute to potential defaults and ultimate recoveries.

These non-agency RMBS and CMBS models are continuously back-tested and updated to reflect current economic and real estate market data. The non-agency MBS and CMBS investment processes will help Western Asset identify securities with attractive relative value across the various sectors of the mortgage markets, including undervalued distressed assets. On a monthly basis, multiple stress analyses will be run to monitor collateral performance, evaluate relative value and serve as the basis for asset dispositions. In making investment decisions, Western Asset will incorporate its views on the economic environment and the outlook for the mortgage markets, including relative valuation, supply and demand trends, the level of interest rates, the shape of the yield curve, prepayment rates, financing and liquidity, commercial and residential real estate prices, delinquencies, default rates, loss severities, and the recovery of various segments of the economy.

Investment Management Team

Set forth below is information regarding the team of professionals at Western Asset responsible for overseeing the day-to-day operations of the Fund. Western Asset utilizes a team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of Western Asset’s senior portfolio managers, research analysts and an in-house economist. Under this team approach, management of client fixed income portfolios will reflect a consensus of interdisciplinary views.

Control Persons

A control person is a person who beneficially owns more than 25% of the voting securities of a company. The Fund currently has no control person.

NET ASSET VALUE

The Fund determines the net asset value of its Common Stock on each day the NYSE is open for business, as of the close of the customary trading session (normally 4:00 p.m. Eastern Time), or any earlier closing time that day. The Fund determines the net asset value per share of Common Stock by dividing the value of the Fund’s securities, cash and other assets (including the value of derivatives and interest accrued but not collected) less all its liabilities (including accrued expenses, the liquidation preference of any outstanding preferred stock and dividends payable) by the total number of shares of Common Stock outstanding. Securities are valued at the mean between the last quoted bid and asked prices provided by an independent pricing service that are based on transactions in corporate obligations, quotations from corporate bond dealers, market transactions in comparable securities and various other relationships between securities. The Fund values portfolio securities for which market quotations are readily available at the last reported sales price or official closing price on the primary market or exchange on which they trade. Under the Fund’s valuation policies and procedures, which were adopted by the Board, the Fund’s short-term investments are valued at amortized cost when the security has 60 days or less to maturity. Determination of the Common Stock’s net asset value is made in accordance with U.S. generally accepted accounting principles.

The Fund values all other securities and assets at their fair value. If events occur that materially affect the value of a security between the time trading ends on the security and the close of the customary trading session of the NYSE, the Fund may value the security at its fair value as determined in good faith by or under the supervision of the Board of Directors of the Fund. The effect of using fair value pricing is that the Common Stock’s net asset value will be subject to the judgment of the Board of Directors or its designee instead of being determined by the market.

Any swap transaction that the Fund enters into may, depending on the applicable interest rate environment, have a positive or negative value for purposes of calculating net asset value. Any cap transaction that the Fund enters into may, depending on the applicable interest rate environment, have no value or a positive value. In addition, accrued payments to the Fund under such transactions will be assets of the Fund and accrued payments by the Fund will be liabilities of the Fund.

The Fund’s Board of Directors has adopted valuation policies and procedures in accordance with SEC Rule 2a-5. The Manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Manager is assisted by the Global Fund Valuation Committee. The Global Fund Valuation Committee is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Manager and the Board of Directors. When determining the reliability of third party pricing information for investments owned by the Fund, the Global Fund Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants. Because the Manager will receive fees from the Fund based on the Fund’s average daily Managed Assets, there is a potential conflict of interest related to the Manager’s role in valuing the Fund’s investments. These fees could influence the valuation advice the Manager provides to the Global Fund Valuation Committee.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Directors, the fair value price is compared against the last available and next available market quotations. The Global Fund Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board of Directors quarterly.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.
