It looks like Sienna Senior Living Inc. (TSE:SIA) is about to go ex-dividend in the next four days. The ex-dividend date is one business day before a company's record date, which is the date on which the company determines which shareholders are entitled to receive a dividend. It is important to be aware of the ex-dividend date because any trade on the stock needs to have been settled on or before the record date. Meaning, you will need to purchase Sienna Senior Living's shares before the 29th of July to receive the dividend, which will be paid on the 13th of August.

The company's next dividend payment will be CA$0.078 per share, and in the last 12 months, the company paid a total of CA$0.94 per share. Calculating the last year's worth of payments shows that Sienna Senior Living has a trailing yield of 5.8% on the current share price of CA$16.27. 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! We need to see whether the dividend is covered by earnings and if it's 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. Sienna Senior Living reported a loss after tax last year, which means it's paying a dividend despite being unprofitable. While this might be a one-off event, this is unlikely to be sustainable in the long term. Given that the company reported a loss last year, we now need to see if it generated enough free cash flow to fund the dividend. If cash earnings don't cover the dividend, the company would have to pay dividends out of cash in the bank, or by borrowing money, neither of which is long-term sustainable. Over the past year it paid out 138% of its free cash flow as dividends, which is uncomfortably high. We're curious about why the company paid out more cash than it generated last year, since this can be one of the early signs that a dividend may be unsustainable.

The main way most investors will assess a company's dividend prospects is by checking the historical rate of dividend growth. In the last 10 years, Sienna Senior Living has lifted its dividend by approximately 1.0% a year on average.
