Is Lindsay Australia Limited (ASX:LAU) a good dividend stock? How can we tell? Dividend paying companies with growing earnings can be highly rewarding in the long term. Unfortunately, it's common for investors to be enticed in by the seemingly attractive yield, and lose money when the company has to cut its dividend payments.

With Lindsay Australia yielding 5.7% and having paid a dividend for over 10 years, many investors likely find the company quite interesting. It would not be a surprise to discover that many investors buy it for the dividends. 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 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. Lindsay Australia paid out 70% of its profit as dividends, over the trailing twelve month period. A payout ratio above 50% generally implies a business is reaching maturity, although it is still possible to reinvest in the business or increase the dividend 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. Lindsay Australia's cash payout ratio last year was 12%, which is quite low and suggests that the dividend was thoroughly covered by cash flow. It's positive to see that Lindsay Australia'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.

Is Lindsay Australia's Balance Sheet Risky?

As Lindsay Australia has a meaningful amount of debt, we need to check its balance sheet to see if the company might have debt risks. A quick check of its financial situation can be done with two ratios: net debt divided by EBITDA (earnings before interest, tax, depreciation and amortisation), and net interest cover. Net debt to EBITDA is a measure of a company's total debt. Net interest cover measures the ability to meet interest payments. Essentially we check that a) the company does not have too much debt, and b) that it can afford to pay the interest. Lindsay Australia has net debt of 0.25 times its EBITDA, which we think is not too troublesome.

Net interest cover can be calculated by dividing earnings before interest and tax (EBIT) by the company's net interest expense. With EBIT of 2.90 times its interest expense, Lindsay Australia's interest cover is starting to look a bit thin.

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. Lindsay Australia 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. Its most recent annual dividend was AU$0.02 per share, effectively flat on its first payment ten years ago.

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

With a relatively unstable dividend, it's even more important to see if earnings per share (EPS) are growing. Why take the risk of a dividend getting cut, unless there's a good chance of bigger dividends in future? It's not great to see that Lindsay Australia's have fallen at approximately 2.6% over the past five years. A modest decline in earnings per share is not great to see, but it doesn't automatically make a dividend unsustainable. Still, we'd vastly prefer to see EPS growth when researching dividend stocks.

Conclusion

Dividend investors should always want to know if a) a company's dividends are affordable, b) if there is a track record of consistent payments, and c) if the dividend is capable of growing. First, we think Lindsay Australia has an acceptable payout ratio and its dividend is well covered by cashflow. Second, earnings per share have been essentially flat, and its history of dividend payments is chequered - having cut its dividend at least once in the past. Ultimately, Lindsay Australia comes up short on our dividend analysis. It's not that we think it is a bad company - just that there are likely more appealing dividend prospects out there on this analysis.
