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 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 can see that AusGroup Limited (SGX:5GJ) does use debt in its business. But the real question is whether this debt is making the company risky.

When Is Debt Dangerous?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. 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 step when considering a company's debt levels is to consider its cash and debt together.

What Is AusGroup's Net Debt?

You can click the graphic below for the historical numbers, but it shows that AusGroup had AU$74.9m of debt in June 2019, down from AU$120.9m, one year before. However, because it has a cash reserve of AU$17.6m, its net debt is less, at about AU$57.3m.

How Strong Is AusGroup's Balance Sheet?

The latest balance sheet data shows that AusGroup had liabilities of AU$51.8m due within a year, and liabilities of AU$69.3m falling due after that. Offsetting this, it had AU$17.6m in cash and AU$68.3m in receivables that were due within 12 months. So its liabilities total AU$35.1m more than the combination of its cash and short-term receivables.

AusGroup has a market capitalization of AU$72.0m, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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).

Weak interest cover of 0.38 times and a disturbingly high net debt to EBITDA ratio of 6.3 hit our confidence in AusGroup like a one-two punch to the gut. The debt burden here is substantial. Worse, AusGroup's EBIT was down 93% over the last year. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that debt. The balance sheet is clearly the area to focus on when you are analysing debt. But you can't view debt in total isolation; since AusGroup will need earnings to service that debt. So when considering debt, it's definitely worth looking at the earnings trend. Click here for an interactive snapshot.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Considering the last three years, AusGroup actually recorded a cash outflow, overall. Debt is far more risky for companies with unreliable free cash flow, so shareholders should be hoping that the past expenditure will produce free cash flow in the future.

Our View

On the face of it, AusGroup'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. Having said that, its ability to handle its total liabilities isn't such a worry. After considering the datapoints discussed, we think AusGroup has too much debt. That sort of riskiness is ok for some, but it certainly doesn't float our boat. Given the risks around AusGroup's use of debt, the sensible thing to do is to check if insiders have been unloading the stock.
