Is Bank of Communications Co., Ltd. (HKG:3328) a good dividend stock? How can we tell? Dividend paying companies with growing earnings can be highly rewarding in the long term. Unfortunately, it's common for investors to be enticed in by the seemingly attractive yield, and lose money when the company has to cut its dividend payments.

With Bank of Communications yielding 6.6% and having paid a dividend for over 10 years, many investors likely find the company quite interesting. It would not be a surprise to discover that many investors buy it for the dividends. When buying stocks for their dividends, you should always run through the checks below, to see if the dividend looks sustainable.

Payout ratios

Dividends are usually paid out of company earnings. If a company is paying more than it earns, then the dividend might become unsustainable - hardly an ideal situation. As a result, we should always investigate whether a company can afford its dividend, measured as a percentage of a company's net income after tax. Looking at the data, we can see that 30% of Bank of Communications's profits were paid out as dividends in the last 12 months. This is a middling range that strikes a nice balance between paying dividends to shareholders, and retaining enough earnings to invest in future growth. Besides, if reinvestment opportunities dry up, the company has room to increase the dividend.

Dividend Volatility

Before buying a stock for its income, we want to see if the dividends have been stable in the past, and if the company has a track record of maintaining its dividend. Bank of Communications has been paying dividends for a long time, but for the purpose of this analysis, we only examine the past 10 years of payments. The dividend has been cut on at least one occasion historically. During the past ten-year period, the first annual payment was CN¥0.18 in 2010, compared to CN¥0.30 last year. Dividends per share have grown at approximately 5.1% per year over this time. The growth in dividends has not been linear, but the CAGR is a decent approximation of the rate of change over this time frame.

Dividends have grown at a reasonable rate, but with at least one substantial cut in the payments, we're not certain this dividend stock would be ideal for someone intending to live on the income.

Dividend Growth Potential

With a relatively unstable dividend, it's even more important to evaluate if earnings per share (EPS) are growing - it's not worth taking the risk on a dividend getting cut, unless you might be rewarded with larger dividends in future. Earnings have grown at around 3.3% a year for the past five years, which is better than seeing them shrink! Bank of Communications is paying out less than half of its earnings, which we like. However, earnings per share are unfortunately not growing much. Might this suggest that the company should pay a higher dividend instead?

We'd also point out that Bank of Communications issued a meaningful number of new shares in the past year. Trying to grow the dividend when issuing new shares reminds us of the ancient Greek tale of Sisyphus - perpetually pushing a boulder uphill. Companies that consistently issue new shares are often suboptimal from a dividend perspective.

Conclusion

Dividend investors should always want to know if a) a company's dividends are affordable, b) if there is a track record of consistent payments, and c) if the dividend is capable of growing. Firstly, we like that Bank of Communications has a low and conservative payout ratio. Second, earnings growth has been ordinary, and its history of dividend payments is chequered - having cut its dividend at least once in the past. While we're not hugely bearish on it, overall we think there are potentially better dividend stocks than Bank of Communications out there.

Earnings growth generally bodes well for the future value of company dividend payments. See if the 17 Bank of Communications analysts we track are forecasting continued growth with our free report on analyst estimates for the company.
