Legendary fund manager Li Lu (who Charlie Munger backed) once said, 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. As with many other companies Interface, Inc. (NASDAQ:TILE) makes use of debt. But is this debt a concern to shareholders?

When Is Debt A Problem?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. Of course, plenty of companies use debt to fund growth, without any negative consequences. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Interface's Debt?

As you can see below, Interface had US$387.6m of debt at June 2024, down from US$475.6m a year prior. On the flip side, it has US$94.2m in cash leading to net debt of about US$293.4m.

A Look At Interface's Liabilities

Zooming in on the latest balance sheet data, we can see that Interface had liabilities of US$214.7m due within 12 months and liabilities of US$550.2m due beyond that. Offsetting this, it had US$94.2m in cash and US$179.6m in receivables that were due within 12 months. So its liabilities total US$491.2m more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Interface has a market capitalization of US$1.05b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).

Interface's net debt is sitting at a very reasonable 1.7 times its EBITDA, while its EBIT covered its interest expense just 4.6 times last year. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. Importantly, Interface grew its EBIT by 34% over the last twelve months, and that growth will make it easier to handle its debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Interface's ability to maintain a healthy balance sheet going forward.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Interface recorded free cash flow worth 56% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

Interface's EBIT growth rate suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But, on a more sombre note, we are a little concerned by its level of total liabilities. Looking at all the aforementioned factors together, it strikes us that Interface can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
