Some investors rely on dividends for growing their wealth, and if you're one of those dividend sleuths, you might be intrigued to know that Cass Information Systems, Inc. (NASDAQ:CASS) is about to go ex-dividend in just three 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. Thus, you can purchase Cass Information Systems' shares before the 4th of June in order to receive the dividend, which the company will pay on the 14th of June.

The company's next dividend payment will be US$0.30 per share, on the back of last year when the company paid a total of US$1.20 to shareholders. Based on the last year's worth of payments, Cass Information Systems has a trailing yield of 2.9% on the current stock price of US$42.10. Dividends are an important source of income to many shareholders, but the health of the business is crucial to maintaining those dividends. We need to see whether the dividend is covered by earnings and if it's growing.

Dividends are usually paid out of company profits, so if a company pays out more than it earned then its dividend is usually at greater risk of being cut. Cass Information Systems paid out 53% of its earnings to investors last year, a normal payout level for most businesses.

Companies that pay out less in dividends than they earn in profits generally have more sustainable dividends. The lower the payout ratio, the more wiggle room the business has before it could be forced to cut the dividend.

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 Cass Information Systems's flat earnings over the past five years. We'd take that over an earnings decline any day, but in the long run, the best dividend stocks all grow their earnings per share.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. Cass Information Systems has delivered 7.1% dividend growth per year on average over the past 10 years.
