The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a 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. We can see that China Resources Gas Group Limited (HKG:1193) does use debt in its business. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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, 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. When we think about a company's use of debt, we first look at cash and debt together.

What Is China Resources Gas Group's Net Debt?

The image below, which you can click on for greater detail, shows that at June 2022 China Resources Gas Group had debt of HK$14.5b, up from HK$12.4b in one year. However, it also had HK$7.00b in cash, and so its net debt is HK$7.54b.

A Look At China Resources Gas Group's Liabilities

According to the last reported balance sheet, China Resources Gas Group had liabilities of HK$50.0b due within 12 months, and liabilities of HK$8.03b due beyond 12 months. Offsetting this, it had HK$7.00b in cash and HK$22.8b in receivables that were due within 12 months. So its liabilities total HK$28.3b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because China Resources Gas Group is worth HK$71.0b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt.

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).

China Resources Gas Group's net debt is only 0.69 times its EBITDA. And its EBIT covers its interest expense a whopping 112 times over. So you could argue it is no more threatened by its debt than an elephant is by a mouse. On the other hand, China Resources Gas Group saw its EBIT drop by 4.4% in the last twelve months. If earnings continue to decline at that rate the company may have increasing difficulty managing its debt load. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine China Resources Gas Group'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.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we always check how much of that EBIT is translated into free cash flow. Over the most recent three years, China Resources Gas Group recorded free cash flow worth 55% 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

When it comes to the balance sheet, the standout positive for China Resources Gas Group was the fact that it seems able to cover its interest expense with its EBIT confidently. But the other factors we noted above weren't so encouraging. For example, its EBIT growth rate makes us a little nervous about its debt. It's also worth noting that China Resources Gas Group is in the Gas Utilities industry, which is often considered to be quite defensive. Considering this range of data points, we think China Resources Gas Group is in a good position to manage its debt levels. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. 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. We've identified 1 warning sign with China Resources Gas Group , and understanding them should be part of your investment process.
