Know This Before Buying National Australia Bank Limited (ASX:NAB) For Its Dividend

Could National Australia Bank Limited (ASX:NAB) be an attractive dividend share to own for the long haul? Investors are often drawn to strong companies with the idea of reinvesting the dividends. Yet sometimes, investors buy a popular dividend stock because of its yield, and then lose money if the company's dividend doesn't live up to expectations.

A high yield and a long history of paying dividends is an appealing combination for National Australia Bank. We'd guess that plenty of investors have purchased it for the income. Some simple analysis can offer a lot of insights when buying a company for its dividend, and we'll go through this below.

Payout ratios

Dividends are typically paid from company earnings. If a company pays more in dividends than it earned, 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. National Australia Bank paid out 93% of its profit as dividends, over the trailing twelve month period. Its payout ratio is quite high, and the dividend is not well covered by earnings. If earnings are growing or the company has a large cash balance, this might be sustainable - still, we think it is a concern.

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. National Australia Bank has been paying dividends for a long time, but for the purpose of this analysis, we only examine the past 10 years of payments. This dividend has been unstable, which we define as having been cut one or more times over this time. During the past ten-year period, the first annual payment was AU$1.70 in 2010, compared to AU$1.66 last year. Dividend payments have shrunk at a rate of less than 1% per annum over this time frame.

A shrinking dividend over a ten-year period is not ideal, and we'd be concerned about investing in a dividend stock that lacks a solid record of growing dividends per share.

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. In the last five years, National Australia Bank's earnings per share have shrunk at approximately 3.5% per annum. If earnings continue to decline, the dividend may come under pressure. Every investor should make an assessment of whether the company is taking steps to stabilise the situation.

Conclusion

When we look at a dividend stock, we need to form a judgement on whether the dividend will grow, if the company is able to maintain it in a wide range of economic circumstances, and if the dividend payout is sustainable. First, it's not great to see how much of its earnings are being paid as dividends. Earnings per share are down, and National Australia Bank's dividend has been cut at least once in the past, which is disappointing. Using these criteria, National Australia Bank looks suboptimal from a dividend investment perspective.

Without at least some growth in earnings per share over time, the dividend will eventually come under pressure either from costs or inflation. See if the 13 analysts are forecasting a turnaround in our free collection of analyst estimates here.
