Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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 Martin Marietta Materials, Inc. (NYSE:MLM) makes use of debt. But is this debt a concern to shareholders?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. 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. The first step when considering a company's debt levels is to consider its cash and debt together.

How Healthy Is Martin Marietta Materials' Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Martin Marietta Materials had liabilities of US$448.8m due within 12 months and liabilities of US$4.28b due beyond that. Offsetting this, it had US$313.9m in cash and US$571.1m in receivables that were due within 12 months. So its liabilities total US$3.85b more than the combination of its cash and short-term receivables.

Since publicly traded Martin Marietta Materials shares are worth a very impressive total of US$21.9b, it seems unlikely that this level of liabilities would be a major threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

With a debt to EBITDA ratio of 1.7, Martin Marietta Materials uses debt artfully but responsibly. And the fact that its trailing twelve months of EBIT was 8.6 times its interest expenses harmonizes with that theme. Also good is that Martin Marietta Materials grew its EBIT at 13% over the last year, further increasing its ability to manage debt. 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 Martin Marietta Materials can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we always check how much of that EBIT is translated into free cash flow. Over the most recent three years, Martin Marietta Materials recorded free cash flow worth 61% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

Martin Marietta Materials's interest cover suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. And we also thought its conversion of EBIT to free cash flow was a positive. Taking all this data into account, it seems to us that Martin Marietta Materials takes a pretty sensible approach to debt. While that brings some risk, it can also enhance returns for shareholders. 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. To that end, you should be aware of the 2 warning signs we've spotted with Martin Marietta Materials .
