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. We can see that Marathon Petroleum Corporation (NYSE:MPC) does use debt in its business. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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. 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.

How Strong Is Marathon Petroleum's Balance Sheet?

The latest balance sheet data shows that Marathon Petroleum had liabilities of US$21.8b due within a year, and liabilities of US$34.0b falling due after that. On the other hand, it had cash of US$7.57b and US$13.2b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$35.0b.

This deficit isn't so bad because Marathon Petroleum is worth a massive US$62.0b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt.

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.

Marathon Petroleum has a low net debt to EBITDA ratio of only 1.3. And its EBIT easily covers its interest expense, being 14.6 times the size. So we're pretty relaxed about its super-conservative use of debt. In fact Marathon Petroleum's saving grace is its low debt levels, because its EBIT has tanked 49% in the last twelve months. Falling earnings (if the trend continues) could eventually make even modest debt quite risky. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Marathon Petroleum can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. During the last three years, Marathon Petroleum produced sturdy free cash flow equating to 77% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.

Our View

Based on what we've seen Marathon Petroleum is not finding it easy, given its EBIT growth rate, but the other factors we considered give us cause to be optimistic. There's no doubt that its ability to to cover its interest expense with its EBIT is pretty flash. Looking at all this data makes us feel a little cautious about Marathon Petroleum's debt levels. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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. For example Marathon Petroleum has 4 warning signs (and 1 which doesn't sit too well with us) we think you should know about.
