Westlake Chemical (NYSE:WLK) Seems To Use Debt Rather Sparingly

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.' 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. We can see that Westlake Chemical Corporation (NYSE:WLK) does use debt in its business. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Westlake Chemical Carry?

The image below, which you can click on for greater detail, shows that at September 2021 Westlake Chemical had debt of US$5.20b, up from US$3.68b in one year. However, because it has a cash reserve of US$3.57b, its net debt is less, at about US$1.63b.

How Healthy Is Westlake Chemical's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Westlake Chemical had liabilities of US$1.90b due within 12 months and liabilities of US$7.34b due beyond that. Offsetting this, it had US$3.57b in cash and US$1.64b in receivables that were due within 12 months. So it has liabilities totalling US$4.03b more than its cash and near-term receivables, combined.

This deficit isn't so bad because Westlake Chemical is worth a massive US$13.2b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Westlake Chemical has a low net debt to EBITDA ratio of only 0.57. And its EBIT easily covers its interest expense, being 14.2 times the size. So we're pretty relaxed about its super-conservative use of debt. Better yet, Westlake Chemical grew its EBIT by 439% last year, which is an impressive improvement. If maintained that growth will make the debt even more manageable in the years ahead. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Westlake Chemical can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. During the last three years, Westlake Chemical 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.

And the good news does not stop there, as its EBIT growth rate also supports that impression! Overall, we don't think Westlake Chemical is taking any bad risks, as its debt load seems modest. So we're not worried about the use of a little leverage on the balance sheet. When analysing debt levels, the balance sheet is the obvious place to start.
