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. Comparing dividend payments to a company's net profit after tax is a simple way of reality-checking whether a dividend is sustainable. In the last year, Tsingtao Brewery paid out 40% of its profit as dividends. A medium payout ratio strikes a good balance between paying dividends, and keeping enough back to invest in the business. Besides, if reinvestment opportunities dry up, the company has room to increase the dividend.

Another important check we do is to see if the free cash flow generated is sufficient to pay the dividend. Tsingtao Brewery's cash payout ratio last year was 23%. Cash flows are typically lumpy, but this looks like an appropriately conservative payout. 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.

While the above analysis focuses on dividends relative to a company's earnings, we do note Tsingtao Brewery's strong net cash position, which will let it pay larger dividends for a time, should it choose.

Dividend Volatility

From the perspective of an income investor who wants to earn dividends for many years, there is not much point buying a stock if its dividend is regularly cut or is not reliable. Tsingtao Brewery 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¥0.22 in 2010, compared to CN¥0.55 last year. Dividends per share have grown at approximately 9.6% per year over this time. The dividends haven't grown at precisely 9.6% every year, but this is a useful way to average out the historical rate of growth.
