Regular readers will know that we love our dividends at Simply Wall St, which is why it's exciting to see CF Industries Holdings, Inc. (NYSE:CF) is about to trade ex-dividend in the next 4 days. The ex-dividend date is one business day before the record date, which is the cut-off date for shareholders to be present on the company's books to be eligible for a dividend payment. 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. Accordingly, CF Industries Holdings investors that purchase the stock on or after the 14th of August will not receive the dividend, which will be paid on the 31st of August.

The company's next dividend payment will be US$0.60 per share, and in the last 12 months, the company paid a total of US$2.40 per share. Calculating the last year's worth of payments shows that CF Industries Holdings has a trailing yield of 2.1% on the current share price of US$114.35. If you buy this business for its dividend, you should have an idea of whether CF Industries Holdings's dividend is reliable and sustainable. As a result, readers should always check whether CF Industries Holdings has been able to grow its dividends, or if the dividend might be cut.

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. CF Industries Holdings has a low and conservative payout ratio of just 15% of its income after tax. A useful secondary check can be to evaluate whether CF Industries Holdings generated enough free cash flow to afford its dividend. Luckily it paid out just 16% of its free cash flow last year.

It's encouraging to see that the dividend is covered by both profit and cash flow. This generally suggests the dividend is sustainable, as long as earnings don't drop precipitously.

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 business enters a downturn and the dividend is cut, the company could see its value fall precipitously. That's why it's comforting to see CF Industries Holdings's earnings have been skyrocketing, up 57% per annum for the past five years. CF Industries Holdings earnings per share have been sprinting ahead like the Road Runner at a track and field day; scarcely stopping even for a cheeky "beep-beep". We also like that it is reinvesting most of its profits in its business.'

CF Industries Holdings has delivered an average of 7.2% per year annual increase in its dividend, based on the past 10 years of dividend payments.
