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. We note that AAR Corp. (NYSE:AIR) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?

What Risk Does Debt Bring?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is AAR's Net Debt?

The image below, which you can click on for greater detail, shows that at February 2023 AAR had debt of US$185.6m, up from US$103.3m in one year. However, because it has a cash reserve of US$52.7m, its net debt is less, at about US$132.9m.

How Healthy Is AAR's Balance Sheet?

According to the last reported balance sheet, AAR had liabilities of US$331.6m due within 12 months, and liabilities of US$274.0m due beyond 12 months. Offsetting these obligations, it had cash of US$52.7m as well as receivables valued at US$329.4m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$223.5m.

Since publicly traded AAR shares are worth a total of US$1.71b, 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). 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).

AAR's net debt is only 0.82 times its EBITDA. And its EBIT easily covers its interest expense, being 19.0 times the size. So we're pretty relaxed about its super-conservative use of debt. On top of that, AAR grew its EBIT by 35% over the last twelve months, and that growth will make it easier to handle its debt. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine AAR's ability to maintain a healthy balance sheet going forward.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. In the last three years, AAR's free cash flow amounted to 31% of its EBIT, less than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.

Our View

AAR's interest cover suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But truth be told we feel its conversion of EBIT to free cash flow does undermine this impression a bit. Taking all this data into account, it seems to us that AAR takes a pretty sensible approach to debt. That means they are taking on a bit more risk, in the hope of boosting shareholder returns. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it.
