Readers hoping to buy Silicon Motion Technology Corporation (NASDAQ:SIMO) for its dividend will need to make their move shortly, as the stock is about to trade ex-dividend. 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. Meaning, you will need to purchase Silicon Motion Technology's shares before the 8th of August to receive the dividend, which will be paid on the 22nd of August.

The company's next dividend payment will be US$0.4975 per share, on the back of last year when the company paid a total of US$2.00 to shareholders. Based on the last year's worth of payments, Silicon Motion Technology stock has a trailing yield of around 3.2% on the current share price of US$62.50. Dividends are a major contributor to investment returns for long term holders, but only if the dividend continues to be paid. That's why we should always check whether the dividend payments appear sustainable, and if the company is growing.

If a company pays out more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. Fortunately Silicon Motion Technology's payout ratio is modest, at just 32% of profit. Yet cash flow is typically more important than profit for assessing dividend sustainability, so we should always check if the company generated enough cash to afford its dividend. It distributed 33% of its free cash flow as dividends, a comfortable payout level for most companies.

It's positive to see that Silicon Motion Technology'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?

Businesses with shrinking earnings are tricky from a dividend perspective. If earnings decline and the company is forced to cut its dividend, investors could watch the value of their investment go up in smoke. Readers will understand then, why we're concerned to see Silicon Motion Technology's earnings per share have dropped 8.5% a year over the past five years. Such a sharp decline casts doubt on the future sustainability of the dividend.

Many investors will assess a company's dividend performance by evaluating how much the dividend payments have changed over time. In the past 10 years, Silicon Motion Technology has increased its dividend at approximately 13% a year on average.

To Sum It Up

Is Silicon Motion Technology an attractive dividend stock, or better left on the shelf? Earnings per share are down meaningfully, although at least the company is paying out a low and conservative percentage of both its earnings and cash flow. It's definitely not great to see earnings falling, but at least there may be some buffer before the dividend needs to be cut. Overall we're not hugely bearish on the stock, but there are likely better dividend investments out there.

In light of that, while Silicon Motion Technology has an appealing dividend, it's worth knowing the risks involved with this stock. Every company has risks, and we've spotted 2 warning signs for Silicon Motion Technology you should know about.
