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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We note that Diodes Incorporated (NASDAQ:DIOD) 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 usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. 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.

What Is Diodes's Debt?

As you can see below, Diodes had US$62.1m of debt at December 2023, down from US$185.4m a year prior. However, it does have US$325.6m in cash offsetting this, leading to net cash of US$263.5m.

A Look At Diodes' Liabilities

We can see from the most recent balance sheet that Diodes had liabilities of US$393.5m falling due within a year, and liabilities of US$164.5m due beyond that. Offsetting this, it had US$325.6m in cash and US$371.9m in receivables that were due within 12 months. So it actually has US$139.6m more liquid assets than total liabilities.

This surplus suggests that Diodes has a conservative balance sheet, and could probably eliminate its debt without much difficulty. Simply put, the fact that Diodes has more cash than debt is arguably a good indication that it can manage its debt safely.

The modesty of its debt load may become crucial for Diodes if management cannot prevent a repeat of the 38% cut to EBIT over the last year. When a company sees its earnings tank, it can sometimes find its relationships with its lenders turn sour. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Diodes can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. While Diodes has net cash on its balance sheet, it's still worth taking a look at its ability to convert earnings before interest and tax (EBIT) to free cash flow, to help us understand how quickly it is building (or eroding) that cash balance. Over the most recent three years, Diodes 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.

Summing Up

While it is always sensible to investigate a company's debt, in this case Diodes has US$263.5m in net cash and a decent-looking balance sheet. So we are not troubled with Diodes's debt use. There's no doubt that we learn most about debt from the balance sheet. But ultimately, every company can contain risks that exist outside of the balance sheet. To that end, you should learn about the 2 warning signs we've spotted with Diodes (including 1 which shouldn't be ignored) .
