Today we'll take a closer look at Link Administration Holdings Limited (ASX:LNK) from a dividend investor's perspective. Owning a strong business and reinvesting the dividends is widely seen as an attractive way of growing your wealth. Yet sometimes, investors buy a stock for its dividend and lose money because the share price falls by more than they earned in dividend payments.

Link Administration Holdings yields a solid 3.5%, although it has only been paying for three years. It's certainly an attractive yield, but readers are likely curious about its staying power. 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. Comparing dividend payments to a company's net profit after tax is a simple way of reality-checking whether a dividend is sustainable. In the last year, Link Administration Holdings paid out 34% of its profit as dividends. This is a medium payout level that leaves enough capital in the business to fund opportunities that might arise, while also rewarding shareholders. One of the risks is that management reinvests the retained capital poorly instead of paying a higher dividend.

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 69% of its free cash flow, which is not bad per se, but does start to limit the amount of cash Link Administration Holdings has available to meet other needs. It's positive to see that Link Administration Holdings'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 Link Administration Holdings's Balance Sheet Risky?

As Link Administration Holdings 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 measures total debt load relative to company earnings (lower = less debt), while net interest cover measures the ability to pay interest on the debt (higher = greater ability to pay interest costs). With net debt of 2.31 times its EBITDA, Link Administration Holdings has a noticeable amount of debt, although if business stays steady, this may not be overly concerning.

We calculated its interest cover by measuring its earnings before interest and tax (EBIT), and dividing this by the company's net interest expense. Net interest cover of 7.54 times its interest expense appears reasonable for Link Administration Holdings, although we're conscious that even high interest cover doesn't make a company bulletproof.

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. The company has been paying a stable dividend for a few years now, but we'd like to see more evidence of consistency over a longer period. During the past three-year period, the first annual payment was AU$0.08 in 2016, compared to AU$0.20 last year. This works out to be a compound annual growth rate (CAGR) of approximately 37% a year over that time.

The dividend has been growing pretty quickly, which could be enough to get us interested even though the dividend history is relatively short. Further research may be warranted.

Dividend Growth Potential

Dividend payments have been consistent over the past few years, but we should always check if earnings per share (EPS) are growing, as this will help maintain the purchasing power of the dividend. It's good to see Link Administration Holdings has been growing its earnings per share at 56% 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.

Conclusion

To summarise, shareholders should always check that Link Administration Holdings's dividends are affordable, that its dividend payments are relatively stable, and that it has decent prospects for growing its earnings and dividend. Above all, we're glad to see that Link Administration Holdings pays out a low fraction of its earnings and, while it paid a higher percentage of cashflow, this also was within a normal range. We were also glad to see it growing earnings, although its dividend history is not as long as we'd like. Overall we think Link Administration Holdings is an interesting dividend stock, although it could be better.
