David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the permanent loss of capital.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. As with many other companies Flowserve Corporation (NYSE:FLS) makes use of debt. But is this debt a concern to shareholders?

When Is Debt Dangerous?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Flowserve's Debt?

As you can see below, Flowserve had US$1.46b of debt at June 2019, down from US$1.52b a year prior. On the flip side, it has US$596.5m in cash leading to net debt of about US$861.5m.

How Strong Is Flowserve's Balance Sheet?

We can see from the most recent balance sheet that Flowserve had liabilities of US$1.06b falling due within a year, and liabilities of US$2.01b due beyond that. On the other hand, it had cash of US$596.5m and US$1.02b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.45b.

While this might seem like a lot, it is not so bad since Flowserve has a market capitalization of US$5.96b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

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).

With a debt to EBITDA ratio of 1.7, Flowserve uses debt artfully but responsibly. And the alluring interest cover (EBIT of 8.3 times interest expense) certainly does not do anything to dispel this impression. Importantly, Flowserve grew its EBIT by 34% over the last twelve months, and that growth will make it easier to handle its debt. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Flowserve 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 the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Flowserve recorded free cash flow worth 57% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Happily, Flowserve's impressive EBIT growth rate implies it has the upper hand on its debt. And we also thought its interest cover was a positive. When we consider the range of factors above, it looks like Flowserve is pretty sensible with its use of debt. That means they are taking on a bit more risk, in the hope of boosting shareholder returns. Of course, we wouldn't say no to the extra confidence that we'd gain if we knew that Flowserve insiders have been buying shares: if you're on the same wavelength, you can find out if insiders are buying by clicking this link.
