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 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 Dorman Products, Inc. (NASDAQ:DORM) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we think about a company's use of debt, we first look at cash and debt together.

What Is Dorman Products's Debt?

You can click the graphic below for the historical numbers, but it shows that Dorman Products had US$575.6m of debt in December 2023, down from US$734.3m, one year before. On the flip side, it has US$36.8m in cash leading to net debt of about US$538.8m.

A Look At Dorman Products' Liabilities

Zooming in on the latest balance sheet data, we can see that Dorman Products had liabilities of US$547.2m due within 12 months and liabilities of US$577.1m due beyond that. On the other hand, it had cash of US$36.8m and US$526.9m worth of receivables due within a year. So its liabilities total US$560.5m more than the combination of its cash and short-term receivables.

Since publicly traded Dorman Products shares are worth a total of US$2.97b, it seems unlikely that this level of liabilities would be a major threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Dorman Products's net debt is sitting at a very reasonable 1.7 times its EBITDA, while its EBIT covered its interest expense just 5.4 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. If Dorman Products can keep growing EBIT at last year's rate of 13% over the last year, then it will find its debt load easier to manage. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Dorman Products can strengthen its balance sheet over time.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. 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, Dorman Products recorded free cash flow of 37% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

When it comes to the balance sheet, the standout positive for Dorman Products was the fact that it seems able to grow its EBIT confidently. However, our other observations weren't so heartening. For example, its conversion of EBIT to free cash flow makes us a little nervous about its debt. When we consider all the elements mentioned above, it seems to us that Dorman Products is managing its debt quite well. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. 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. Case in point: We've spotted 1 warning sign for Dorman Products you should be aware of.
