Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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 Westlake Corporation (NYSE:WLK) makes use of debt. But should shareholders be worried about its use of debt?

When Is Debt Dangerous?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Westlake's Debt?

The chart below, which you can click on for greater detail, shows that Westlake had US$4.89b in debt in March 2024; about the same as the year before. However, it also had US$3.11b in cash, and so its net debt is US$1.78b.

How Strong Is Westlake's Balance Sheet?

The latest balance sheet data shows that Westlake had liabilities of US$2.66b due within a year, and liabilities of US$7.45b falling due after that. Offsetting these obligations, it had cash of US$3.11b as well as receivables valued at US$1.69b due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$5.31b.

While this might seem like a lot, it is not so bad since Westlake has a huge market capitalization of US$18.4b, and so it could probably strengthen its balance sheet by raising capital if it needed to. However, it is still worthwhile taking a close look at its ability to pay off debt.

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). 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).

Westlake has a low net debt to EBITDA ratio of only 0.94. And its EBIT easily covers its interest expense, being 15.6 times the size. So we're pretty relaxed about its super-conservative use of debt. In fact Westlake's saving grace is its low debt levels, because its EBIT has tanked 64% in the last twelve months. When it comes to paying off debt, falling earnings are no more useful than sugary sodas are for your health. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Westlake'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 always check how much of that EBIT is translated into free cash flow. During the last three years, Westlake produced sturdy free cash flow equating to 73% 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.

Our View

Based on what we've seen Westlake is not finding it easy, given its EBIT growth rate, but the other factors we considered give us cause to be optimistic. There's no doubt that its ability to to cover its interest expense with its EBIT is pretty flash. Considering this range of data points, we think Westlake is in a good position to manage its debt levels. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. Be aware that Westlake is showing 3 warning signs in our investment analysis , you should know about...
