The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. Importantly, Brunswick Corporation (NYSE:BC) does carry debt. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

What Is Brunswick's Debt?

The image below, which you can click on for greater detail, shows that at June 2024 Brunswick had debt of US$2.83b, up from US$2.51b in one year. However, it does have US$577.0m in cash offsetting this, leading to net debt of about US$2.25b.

How Healthy Is Brunswick's Balance Sheet?

We can see from the most recent balance sheet that Brunswick had liabilities of US$1.61b falling due within a year, and liabilities of US$2.77b due beyond that. Offsetting this, it had US$577.0m in cash and US$530.0m in receivables that were due within 12 months. So it has liabilities totalling US$3.28b more than its cash and near-term receivables, combined.

This deficit is considerable relative to its market capitalization of US$5.41b, so it does suggest shareholders should keep an eye on Brunswick's use of debt. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Brunswick's net debt is sitting at a very reasonable 2.5 times its EBITDA, while its EBIT covered its interest expense just 6.1 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, Brunswick's EBIT fell a jaw-dropping 31% in the last twelve months. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Brunswick can strengthen its balance sheet over time.

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. Looking at the most recent three years, Brunswick recorded free cash flow of 28% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

Mulling over Brunswick's attempt at (not) growing its EBIT, we're certainly not enthusiastic. Having said that, its ability to cover its interest expense with its EBIT isn't such a worry. Looking at the bigger picture, it seems clear to us that Brunswick's use of debt is creating risks for the company. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. There's no doubt that we learn most about debt from the balance sheet. But ultimately, every company can contain risks that exist outside of the balance sheet. These risks can be hard to spot. Every company has them, and we've spotted 1 warning sign for Brunswick you should know about.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
