Standard Motor Products, Inc. (NYSE:SMP) is about to trade ex-dividend in the next 3 days. The ex-dividend date occurs one day before the record date, which is the day on which shareholders need to be on the company's books in order to receive a 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 Standard Motor Products' shares before the 15th of May in order to receive the dividend, which the company will pay on the 1st of June.

The company's upcoming dividend is US$0.33 a share, following on from the last 12 months, when the company distributed a total of US$1.32 per share to shareholders. Based on the last year's worth of payments, Standard Motor Products stock has a trailing yield of around 3.3% on the current share price of US$40.40. Dividends are a major contributor to investment returns for long term holders, but only if the dividend continues to be paid. 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. Fortunately Standard Motor Products's payout ratio is modest, at just 34% of profit. 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. Over the last year it paid out 71% of its free cash flow as dividends, within the usual range for most companies.

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 with flat earnings can still be attractive dividend payers, but it is important to be more conservative with your approach and demand a greater margin for safety when it comes to dividend sustainability. If earnings fall far enough, the company could be forced to cut its dividend. That explains why we're not overly excited about Standard Motor Products'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. Earnings growth has been slim and the company is paying out more than half of its earnings. While there is some room to both increase the payout ratio and reinvest in the business, generally the higher a payout ratio goes, the lower a company's prospects for future growth.

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, Standard Motor Products has lifted its dividend by approximately 8.2% a year on average.

The Bottom Line

From a dividend perspective, should investors buy or avoid Standard Motor Products? Standard Motor Products has struggled to grow earnings per share, and it's paying out less than half of its earnings and more than half its cash flow to shareholders as dividends. Overall, it's not a bad combination, but we feel that there are likely more attractive dividend prospects out there.

With that in mind, a critical part of thorough stock research is being aware of any risks that stock currently faces.
