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 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 Shenzhen Expressway Corporation Limited (HKG:548) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?

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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

How Much Debt Does Shenzhen Expressway Carry?

As you can see below, at the end of June 2022, Shenzhen Expressway had CN¥33.4b of debt, up from CN¥22.6b a year ago. Click the image for more detail. However, it also had CN¥5.92b in cash, and so its net debt is CN¥27.4b.

How Strong Is Shenzhen Expressway's Balance Sheet?

The latest balance sheet data shows that Shenzhen Expressway had liabilities of CN¥20.2b due within a year, and liabilities of CN¥23.8b falling due after that. Offsetting these obligations, it had cash of CN¥5.92b as well as receivables valued at CN¥2.28b due within 12 months. So it has liabilities totalling CN¥35.8b more than its cash and near-term receivables, combined.

The deficiency here weighs heavily on the CN¥10.7b company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we definitely think shareholders need to watch this one closely. After all, Shenzhen Expressway would likely require a major re-capitalisation if it had to pay its creditors today.

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). 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 net debt to EBITDA ratio of 5.6, it's fair to say Shenzhen Expressway does have a significant amount of debt. However, its interest coverage of 6.4 is reasonably strong, which is a good sign. Shareholders should be aware that Shenzhen Expressway's EBIT was down 25% last year. If that decline continues then paying off debt will be harder than selling foie gras at a vegan convention. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Shenzhen Expressway'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 we always check how much of that EBIT is translated into free cash flow. Over the last three years, Shenzhen Expressway recorded negative free cash flow, in total. Debt is usually more expensive, and almost always more risky in the hands of a company with negative free cash flow. Shareholders ought to hope for an improvement.

Our View

To be frank both Shenzhen Expressway's EBIT growth rate and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. But at least it's pretty decent at covering its interest expense with its EBIT; that's encouraging. We should also note that Infrastructure industry companies like Shenzhen Expressway commonly do use debt without problems. Taking into account all the aforementioned factors, it looks like Shenzhen Expressway has too much debt. While some investors love that sort of risky play, it's certainly not our cup of tea. 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. Case in point: We've spotted 4 warning signs for Shenzhen Expressway you should be aware of, and 1 of them shouldn't be ignored.
