Warren Buffett famously said, 'Volatility is far from synonymous with risk.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. As with many other companies Martin Marietta Materials, Inc. (NYSE:MLM) makes use of debt. But the more important question is: how much risk is that debt creating?

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. 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. 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.

A Look At Martin Marietta Materials' Liabilities

The latest balance sheet data shows that Martin Marietta Materials had liabilities of US$1.20b due within a year, and liabilities of US$6.30b falling due after that. Offsetting these obligations, it had cash of US$109.0m as well as receivables valued at US$921.0m due within 12 months. So its liabilities total US$6.46b more than the combination of its cash and short-term receivables.

Of course, Martin Marietta Materials has a titanic market capitalization of US$35.5b, so these liabilities are probably manageable. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

We'd say that Martin Marietta Materials's moderate net debt to EBITDA ratio ( being 2.1), indicates prudence when it comes to debt. And its strong interest cover of 13.2 times, makes us even more comfortable. If Martin Marietta Materials 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 it is future earnings, more than anything, that will determine Martin Marietta Materials's ability to maintain a healthy balance sheet going forward. 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 business needs free cash flow to pay off debt; accounting profits just don't cut it. So it's worth checking how much of that EBIT is backed by free cash flow. Looking at the most recent three years, Martin Marietta Materials recorded free cash flow of 44% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

Happily, Martin Marietta Materials's impressive interest cover implies it has the upper hand on its debt. And we also thought its EBIT growth rate was a positive. All these things considered, it appears that Martin Marietta Materials can comfortably handle its current debt levels. 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. 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. We've identified 3 warning signs with Martin Marietta Materials (at least 1 which is potentially serious) , and understanding them should be part of your investment process.
