Dividend paying stocks like Perrigo Company plc (NYSE:PRGO) tend to be popular with investors, and for good reason - some research suggests a significant amount of all stock market returns come from reinvested dividends. 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.

While Perrigo's 1.8% dividend yield is not the highest, we think its lengthy payment history is quite interesting. 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. In the last year, Perrigo paid out 76% of its profit as dividends. 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.

Another important check we do is to see if the free cash flow generated is sufficient to pay the dividend. With a cash payout ratio of 108%, Perrigo's dividend payments are poorly covered by cash flow. While Perrigo'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 Perrigo's ability to maintain its dividend.

Is Perrigo's Balance Sheet Risky?

As Perrigo has a meaningful amount of debt, we need to check its balance sheet to see if the company might have debt risks. A rough way to check this is with these two simple ratios: a) net debt divided by EBITDA (earnings before interest, tax, depreciation and amortisation), and b) 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 3.55 times its EBITDA, investors are starting to take on a meaningful amount of risk, should the business enter a downturn.

We calculated its interest cover by measuring its earnings before interest and tax (EBIT), and dividing this by the company's net interest expense. Interest cover of 3.46 times its interest expense is starting to become a concern for Perrigo, and be aware that lenders may place additional restrictions on the company as well.

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. Perrigo has been paying dividends for a long time, but for the purpose of this analysis, we only examine the past 10 years of payments. The dividend has been stable over the past 10 years, which is great. We think this could suggest some resilience to the business and its dividends. During the past ten-year period, the first annual payment was US$0.22 in 2010, compared to US$0.90 last year. This works out to be a compound annual growth rate (CAGR) of approximately 15% a year over that time.

With rapid dividend growth and no notable cuts to the dividend over a lengthy period of time, we think this company has a lot going for it.

Dividend Growth Potential

While dividend payments have been relatively reliable, it would also be nice if earnings per share (EPS) were growing, as this is essential to maintaining the dividend's purchasing power over the long term. Perrigo's EPS have fallen by approximately 16% per year during the past five years. A sharp decline in earnings per share is not great from from a dividend perspective, as even conservative payout ratios can come under pressure if earnings fall far enough.

Conclusion

To summarise, shareholders should always check that Perrigo's dividends are affordable, that its dividend payments are relatively stable, and that it has decent prospects for growing its earnings and dividend. First, we think Perrigo has an acceptable payout ratio, although its dividend was not well covered by cashflow. Second, earnings per share have actually shrunk, but at least the dividends have been relatively stable. In summary, Perrigo has a number of shortcomings that we'd find it hard to get past. Things could change, but we think there are a number of better ideas out there.

Investors generally tend to favour companies with a consistent, stable dividend policy as opposed to those operating an irregular one.
