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. Comparing dividend payments to a company's net profit after tax is a simple way of reality-checking whether a dividend is sustainable. Sands China paid out 52% of its profit as dividends, over the trailing twelve month period. This is a healthy payout ratio, and while it does limit the amount of earnings that can be reinvested in the business, there is also some room to lift the payout ratio over time.

In addition to comparing dividends against profits, we should inspect whether the company generated enough cash to pay its dividend. The company paid out 88% of its free cash flow as dividends last year, which is adequate, but reduces the wriggle room in the event of a downturn. It's positive to see that Sands China'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

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. Looking at the last decade of data, we can see that Sands China paid its first dividend at least eight years ago. It's good to see that Sands China has been paying a dividend for a number of years. However, the dividend has been cut at least once in the past, and we're concerned that what has been cut once, could be cut again. During the past eight-year period, the first annual payment was US$0.15 in 2012, compared to US$0.25 last year. Dividends per share have grown at approximately 6.8% 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.
