Is NGK Insulators (TSE:5333) Using Too Much Debt?

Published
TSE:5333

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.' 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. Importantly, NGK Insulators, Ltd. (TSE:5333) does carry debt. But should shareholders be worried about its use of debt?

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 thing to do when considering how much debt a business uses is to look at its cash and debt together.

How Healthy Is NGK Insulators' Balance Sheet?

The latest balance sheet data shows that NGK Insulators had liabilities of JP¥175.8b due within a year, and liabilities of JP¥248.5b falling due after that. Offsetting these obligations, it had cash of JP¥242.7b as well as receivables valued at JP¥117.6b due within 12 months. So its liabilities total JP¥64.1b more than the combination of its cash and short-term receivables.

Since publicly traded NGK Insulators shares are worth a total of JP¥612.2b, it seems unlikely that this level of liabilities would be a major threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

NGK Insulators's net debt is only 0.14 times its EBITDA. And its EBIT easily covers its interest expense, being 63.0 times the size. So we're pretty relaxed about its super-conservative use of debt. NGK Insulators's EBIT was pretty flat over the last year, but that shouldn't be an issue given the it doesn't have a lot of debt. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if NGK Insulators can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of that EBIT is backed by free cash flow. During the last three years, NGK Insulators produced sturdy free cash flow equating to 77% 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.
