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. COSCO SHIPPING Ports paid out 41% of its profit as dividends, over the trailing twelve month period. This is a medium payout level that leaves enough capital in the business to fund opportunities that might arise, while also rewarding shareholders. Plus, there is room to increase the payout ratio over time.

Another important check we do is to see if the free cash flow generated is sufficient to pay the dividend. Unfortunately, while COSCO SHIPPING Ports pays a dividend, it also reported negative free cash flow last year. While there may be a good reason for this, it's not ideal from a dividend perspective.

Is COSCO SHIPPING Ports's Balance Sheet Risky?

As COSCO SHIPPING Ports 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. With net debt of 4.93 times its EBITDA, investors are starting to take on a meaningful amount of risk, should the business enter a downturn.

Net interest cover can be calculated by dividing earnings before interest and tax (EBIT) by the company's net interest expense. Interest cover of 2.64 times its interest expense is starting to become a concern for COSCO SHIPPING Ports, 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. COSCO SHIPPING Ports 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 US$0.049 in 2010, compared to US$0.042 last year. The dividend has shrunk at around 1.4% a year during that period. COSCO SHIPPING Ports's dividend hasn't shrunk linearly at 1.4% per annum, but the CAGR is a useful estimate of the historical rate of change.

When a company's per-share dividend falls we question if this reflects poorly on either external business conditions, or the company's capital allocation decisions. Either way, we find it hard to get excited about a company with a declining dividend.

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? COSCO SHIPPING Ports's earnings per share have been essentially flat over the past five years. Over the long term, steady earnings per share is a risk as the value of the dividends can be reduced by inflation.

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. COSCO SHIPPING Ports has a low payout ratio, which we like, although it paid out virtually all of its generated cash. Earnings per share have been falling, and the company has cut its dividend at least once in the past. From a dividend perspective, this is a cause for concern. In summary, COSCO SHIPPING Ports 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.

Without at least some growth in earnings per share over time, the dividend will eventually come under pressure either from costs or inflation. Businesses can change though, and we think it would make sense to see what analysts are forecasting for the company.
