Payout ratios

Companies (usually) pay dividends out of their earnings. If a company is paying more than it earns, the dividend might have to be cut. 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. In the last year, Yanzhou Coal Mining paid out 29% 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. Plus, there is room to increase the payout ratio over time.

We also measure dividends paid against a company's levered free cash flow, to see if enough cash was generated to cover the dividend. The company paid out 67% of its free cash flow, which is not bad per se, but does start to limit the amount of cash Yanzhou Coal Mining has available to meet other needs. It's positive to see that Yanzhou Coal Mining'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.

Dividend Volatility

One of the major risks of relying on dividend income, is the potential for a company to struggle financially and cut its dividend. Not only is your income cut, but the value of your investment declines as well - nasty. For the purpose of this article, we only scrutinise the last decade of Yanzhou Coal Mining's dividend payments. This dividend has been unstable, which we define as having fallen by at least 20% one or more times over this time. During the past ten-year period, the first annual payment was CN¥0.40 in 2009, compared to CN¥0.54 last year. Dividends per share have grown at approximately 3.0% 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.

We're glad to see the dividend has risen, but with a limited rate of growth and fluctuations in the payments, we don't think this is an attractive combination.

Dividend Growth Potential

Given that the dividend has been cut in the past, we need to check if earnings are growing and if that might lead to stronger dividends in the future. It's good to see Yanzhou Coal Mining has been growing its earnings per share at 49% a year over the past five years. With high earnings per share growth in recent times and a modest payout ratio, we think this is an attractive combination if earnings can be reinvested to generate further growth.

We'd also point out that Yanzhou Coal Mining 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

To summarise, shareholders should always check that Yanzhou Coal Mining's dividends are affordable, that its dividend payments are relatively stable, and that it has decent prospects for growing its earnings and dividend. Yanzhou Coal Mining's dividend payout ratios are within normal bounds, although we note its cash flow is not as strong as the income statement would suggest. Next, earnings growth has been good, but unfortunately the dividend has been cut at least once in the past. Overall we think Yanzhou Coal Mining is an interesting dividend stock, although it could be better.

Companies that are growing earnings tend to be the best dividend stocks over the long term. See what the 14 analysts we track are forecasting for Yanzhou Coal Mining for free with public analyst estimates for the company.
