It looks like Sealed Air Corporation (NYSE:SEE) is about to go ex-dividend in the next 4 days. The ex-dividend date is usually set to be one business day before the record date, which is the cut-off date on which you must be present on the company's books as a shareholder in order to receive the dividend. The ex-dividend date is of consequence because whenever a stock is bought or sold, the trade takes at least one business day to settle. Thus, you can purchase Sealed Air's shares before the 14th of March in order to receive the dividend, which the company will pay on the 28th of March.

The company's next dividend payment will be US$0.20 per share, on the back of last year when the company paid a total of US$0.80 to shareholders. Based on the last year's worth of payments, Sealed Air stock has a trailing yield of around 2.5% on the current share price of US$31.93. Dividends are an important source of income to many shareholders, but the health of the business is crucial to maintaining those dividends. So we need to check whether the dividend payments are covered, and if earnings are growing.

Dividends are typically paid out of company income, so if a company pays out more than it earned, its dividend is usually at a higher risk of being cut. Sealed Air paid out a comfortable 43% of its profit last year. That said, even highly profitable companies sometimes might not generate enough cash to pay the dividend, which is why we should always check if the dividend is covered by cash flow. Luckily it paid out just 23% of its free cash flow last year.

It's positive to see that Sealed Air's dividend is covered by both profits and cash flow, since this is generally a sign that the dividend is sustainable, and a lower payout ratio usually suggests a greater margin of safety before the dividend gets cut.

Have Earnings And Dividends Been Growing?

Companies that aren't growing their earnings can still be valuable, but it is even more important to assess the sustainability of the dividend if it looks like the company will struggle to grow. If business enters a downturn and the dividend is cut, the company could see its value fall precipitously. That explains why we're not overly excited about Sealed Air's flat earnings over the past five years. Better than seeing them fall off a cliff, for sure, but the best dividend stocks grow their earnings meaningfully over the long run.

Many investors will assess a company's dividend performance by evaluating how much the dividend payments have changed over time. In the past 10 years, Sealed Air has increased its dividend at approximately 4.4% a year on average.

To Sum It Up

From a dividend perspective, should investors buy or avoid Sealed Air? While it's not great to see that earnings per share are effectively flat over the 10-year period we checked, at least the payout ratios are low and conservative. Overall, it's hard to get excited about Sealed Air from a dividend perspective.
