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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. We note that NagaCorp Ltd. (HKG:3918) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

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. If things get really bad, the lenders can take control of the business. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth 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 NagaCorp's Debt?

As you can see below, NagaCorp had US$544.8m of debt, at June 2022, which is about the same as the year before. You can click the chart for greater detail. However, it also had US$215.3m in cash, and so its net debt is US$329.5m.

How Strong Is NagaCorp's Balance Sheet?

According to the last reported balance sheet, NagaCorp had liabilities of US$187.9m due within 12 months, and liabilities of US$623.3m due beyond 12 months. Offsetting this, it had US$215.3m in cash and US$37.5m in receivables that were due within 12 months. So its liabilities total US$558.5m more than the combination of its cash and short-term receivables.

Since publicly traded NagaCorp shares are worth a total of US$2.88b, it seems unlikely that this level of liabilities would be a major threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

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).

While NagaCorp has a quite reasonable net debt to EBITDA multiple of 2.4, its interest cover seems weak, at 0.56. The main reason for this is that it has such high depreciation and amortisation. While companies often boast that these charges are non-cash, most such businesses will therefore require ongoing investment (that is not expensed.) In any case, it's safe to say the company has meaningful debt. Shareholders should be aware that NagaCorp's EBIT was down 75% last year. If that decline continues then paying off debt will be harder than selling foie gras at a vegan convention. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine NagaCorp's ability to maintain a healthy balance sheet going forward.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the most recent three years, NagaCorp recorded free cash flow worth 52% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

On the face of it, NagaCorp's interest cover left us tentative about the stock, and its EBIT growth rate was no more enticing than the one empty restaurant on the busiest night of the year. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. Looking at the balance sheet and taking into account all these factors, we do believe that debt is making NagaCorp stock a bit risky. Some people like that sort of risk, but we're mindful of the potential pitfalls, so we'd probably prefer it carry less debt. In light of our reservations about the company's balance sheet, it seems sensible to check if insiders have been selling shares recently.
