It looks like Celanese Corporation (NYSE:CE) 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 an important date to be aware of as any purchase of the stock made on or after this date might mean a late settlement that doesn't show on the record date. Accordingly, Celanese investors that purchase the stock on or after the 23rd of July will not receive the dividend, which will be paid on the 9th of August.

The company's next dividend payment will be US$0.68 per share, and in the last 12 months, the company paid a total of US$2.72 per share. Last year's total dividend payments show that Celanese has a trailing yield of 1.8% on the current share price of $152.35. We love seeing companies pay a dividend, but it's also important to be sure that laying the golden eggs isn't going to kill our golden goose! So we need to check whether the dividend payments are covered, and if earnings are growing.

Dividends are typically paid from company earnings. If a company pays more in dividends than it earned in profit, then the dividend could be unsustainable. Celanese paid out just 14% of its profit last year, which we think is conservatively low and leaves plenty of margin for unexpected circumstances. Yet cash flows are even more important than profits for assessing a dividend, so we need to see if the company generated enough cash to pay its distribution. Thankfully its dividend payments took up just 34% of the free cash flow it generated, which is a comfortable payout ratio.

It's positive to see that Celanese'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?

Stocks in companies that generate sustainable earnings growth often make the best dividend prospects, as it is easier to lift the dividend when earnings are rising. If earnings decline and the company is forced to cut its dividend, investors could watch the value of their investment go up in smoke. That's why it's comforting to see Celanese's earnings have been skyrocketing, up 55% per annum for the past five years. Earnings per share have been growing very quickly, and the company is paying out a relatively low percentage of its profit and cash flow. This is a very favourable combination that can often lead to the dividend multiplying over the long term, if earnings grow and the company pays out a higher percentage of its earnings.
