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 90% of Data#3's profits were paid out as dividends in the last 12 months. Paying out a majority of its earnings limits the amount that can be reinvested in the business. This may indicate a commitment to paying a dividend, or a dearth of investment opportunities.

We also measure dividends paid against a company's levered free cash flow, to see if enough cash was generated to cover the dividend. Data#3 paid out 270% of its free cash flow last year, suggesting the dividend is poorly covered by cash flow. Paying out more than 100% of your free cash flow in dividends is generally not a long-term, sustainable state of affairs, so we think shareholders should watch this metric closely. While Data#3's dividends were covered by the company's reported profits, free cash flow is somewhat more important, so it's not great to see that the company didn't generate enough cash to pay its dividend. Were it to repeatedly pay dividends that were not well covered by cash flow, this could be a risk to Data#3's ability to maintain its 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. Data#3 has been paying dividends for a long time, but for the purpose of this analysis, we only examine the past 10 years of payments. Its dividend payments have fallen by 20% or more on at least one occasion over the past ten years. During the past ten-year period, the first annual payment was AU$0.05 in 2009, compared to AU$0.10 last year. Dividends per share have grown at approximately 7.4% per year over this time. The dividends haven't grown at precisely 7.4% every year, but this is a useful way to average out the historical rate of growth.
