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 note that Comfort Systems USA, Inc. (NYSE:FIX) does have debt on its balance sheet. 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. If things get really bad, the lenders can take control of the business. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

How Healthy Is Comfort Systems USA's Balance Sheet?

The latest balance sheet data shows that Comfort Systems USA had liabilities of US$968.2m due within a year, and liabilities of US$574.6m falling due after that. Offsetting these obligations, it had cash of US$69.1m as well as receivables valued at US$1.11b due within 12 months. So its liabilities total US$364.6m more than the combination of its cash and short-term receivables.

Given Comfort Systems USA has a market capitalization of US$3.72b, it's hard to believe these liabilities pose much threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

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). 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).

Comfort Systems USA's net debt is only 1.2 times its EBITDA. And its EBIT covers its interest expense a whopping 24.1 times over. So we're pretty relaxed about its super-conservative use of debt. Also good is that Comfort Systems USA grew its EBIT at 14% over the last year, further increasing its ability to manage 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 Comfort Systems USA's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Happily for any shareholders, Comfort Systems USA actually produced more free cash flow than EBIT over the last three years. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.

Our View

The good news is that Comfort Systems USA's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. And that's just the beginning of the good news since its conversion of EBIT to free cash flow is also very heartening. Looking at the bigger picture, we think Comfort Systems USA'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. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.
