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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We note that Martin Marietta Materials, Inc. (NYSE:MLM) does have debt on its balance sheet. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. If things get really bad, the lenders can take control of the business. 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. When we examine debt levels, we first consider both cash and debt levels, together.

How Healthy Is Martin Marietta Materials' Balance Sheet?

We can see from the most recent balance sheet that Martin Marietta Materials had liabilities of US$1.43b falling due within a year, and liabilities of US$5.93b due beyond that. Offsetting this, it had US$2.65b in cash and US$714.0m in receivables that were due within 12 months. So its liabilities total US$4.00b more than the combination of its cash and short-term receivables.

Given Martin Marietta Materials has a humongous market capitalization of US$34.2b, it's hard to believe these liabilities pose much threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

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). 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).

Martin Marietta Materials has a low net debt to EBITDA ratio of only 0.84. And its EBIT easily covers its interest expense, being 15.1 times the size. So we're pretty relaxed about its super-conservative use of debt. Another good sign is that Martin Marietta Materials has been able to increase its EBIT by 24% in twelve months, making it easier to pay down debt. When analysing debt levels, the balance sheet is the obvious place to start. 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 company can only pay off debt with cold hard cash, not accounting profits. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Martin Marietta Materials produced sturdy free cash flow equating to 53% of its EBIT, about what we'd expect. 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 the good news does not stop there, as its EBIT growth rate also supports that impression! Looking at the bigger picture, we think Martin Marietta Materials's use of debt seems quite reasonable and we're not concerned about it. While debt does bring risk, when used wisely it can also bring a higher return on equity. 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.
