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.' 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. As with many other companies i-plug,Inc. (TSE:4177) makes use of debt. But is this debt a concern to shareholders?
Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. 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.
The image below, which you can click on for greater detail, shows that i-plugInc had debt of JP¥254.0m at the end of September 2025, a reduction from JP¥634.0m over a year. However, it does have JP¥3.36b in cash offsetting this, leading to net cash of JP¥3.11b.
According to the last reported balance sheet, i-plugInc had liabilities of JP¥3.91b due within 12 months, and liabilities of JP¥91.0m due beyond 12 months. Offsetting these obligations, it had cash of JP¥3.36b as well as receivables valued at JP¥216.0m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by JP¥423.0m.
Given i-plugInc has a market capitalization of JP¥6.17b, it's hard to believe these liabilities pose much threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward. While it does have liabilities worth noting, i-plugInc also has more cash than debt, so we're pretty confident it can manage its debt safely.

On the other hand, i-plugInc's EBIT dived 16%, over the last year. If that rate of decline in earnings continues, the company could find itself in a tight spot. There's no doubt that we learn most about debt from the balance sheet. But it is i-plugInc's earnings that will influence how the balance sheet holds up in the future. So when considering debt, it's definitely worth looking at the earnings trend. Click here for an interactive snapshot.
But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. While i-plugInc 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. Happily for any shareholders, i-plugInc actually produced more free cash flow than EBIT over the last two years. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.
While it is always sensible to look at a company's total liabilities, it is very reassuring that i-plugInc has JP¥3.11b in net cash. And it impressed us with free cash flow of JP¥734m, being 139% of its EBIT. So we are not troubled with i-plugInc's debt use. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. For instance, we've identified 2 warning signs for i-plugInc that you should be aware of.
