Readers hoping to buy West Bancorporation, Inc. (NASDAQ:WTBA) for its dividend will need to make their move shortly, as the stock is about to trade ex-dividend. 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. 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. Accordingly, West Bancorporation investors that purchase the stock on or after the 5th of August will not receive the dividend, which will be paid on the 19th of August.

The company's upcoming dividend is US$0.26 a share, following on from the last 12 months, when the company distributed a total of US$1.00 per share to shareholders. Looking at the last 12 months of distributions, West Bancorporation has a trailing yield of approximately 3.6% on its current stock price of US$27.77. Dividends are an important source of income to many shareholders, but the health of the business is crucial to maintaining those dividends. That's why we should always check whether the dividend payments appear sustainable, and if the company is 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. Fortunately West Bancorporation's payout ratio is modest, at just 44% of profit.

When a company paid out less in dividends than it earned in profit, this generally suggests its dividend is affordable. The lower the % of its profit that it pays out, the greater the margin of safety for the dividend if the business enters a downturn.

Have Earnings And Dividends Been Growing?

Companies with consistently growing earnings per share generally make the best dividend stocks, as they usually find it easier to grow dividends per share. If business enters a downturn and the dividend is cut, the company could see its value fall precipitously. This is why it's a relief to see West Bancorporation earnings per share are up 2.5% per annum over the last five years.

The main way most investors will assess a company's dividend prospects is by checking the historical rate of dividend growth. West Bancorporation has delivered an average of 4.6% per year annual increase in its dividend, based on the past 10 years of dividend payments. We're glad to see dividends rising alongside earnings over a number of years, which may be a sign the company intends to share the growth with shareholders.

To Sum It Up

Should investors buy West Bancorporation for the upcoming dividend? It has been growing its earnings per share somewhat in recent years, although it reinvests more than half its earnings in the business, which could suggest there are some growth projects that have not yet reached fruition. In summary, West Bancorporation appears to have some promise as a dividend stock, and we'd suggest taking a closer look at it.
