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 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 Allegion plc (NYSE:ALLE) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. 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. 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.

What Is Allegion's Net Debt?

As you can see below, at the end of March 2023, Allegion had US$2.12b of debt, up from US$1.44b a year ago. Click the image for more detail. However, it does have US$292.8m in cash offsetting this, leading to net debt of about US$1.83b.

How Healthy Is Allegion's Balance Sheet?

According to the last reported balance sheet, Allegion had liabilities of US$668.5m due within 12 months, and liabilities of US$2.41b due beyond 12 months. Offsetting this, it had US$292.8m in cash and US$445.0m in receivables that were due within 12 months. So its liabilities total US$2.34b more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Allegion has a market capitalization of US$9.49b, 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.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

With a debt to EBITDA ratio of 2.4, Allegion uses debt artfully but responsibly. And the fact that its trailing twelve months of EBIT was 7.9 times its interest expenses harmonizes with that theme. Also relevant is that Allegion has grown its EBIT by a very respectable 27% in the last year, thus enhancing its ability 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 Allegion'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.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. During the last three years, Allegion produced sturdy free cash flow equating to 74% of its EBIT, about what we'd expect. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Happily, Allegion's impressive EBIT growth rate implies it has the upper hand on its debt. 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 Allegion's use of debt seems quite reasonable and we're not concerned about it. After all, sensible leverage can boost returns on equity. 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 Allegion .

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
