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. So we need to be form a view on if a company's dividend is sustainable, relative to its net profit after tax. Looking at the data, we can see that 32% of Northern Trust's profits were paid out as dividends in the last 12 months. A medium payout ratio strikes a good balance between paying dividends, and keeping enough back to invest in the business. Besides, if reinvestment opportunities dry up, the company has room to increase the dividend.

Dividend Volatility

Before buying a stock for its income, we want to see if the dividends have been stable in the past, and if the company has a track record of maintaining its dividend. For the purpose of this article, we only scrutinise the last decade of Northern Trust's dividend 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$1.12 in 2009, compared to US$2.40 last year. Dividends per share have grown at approximately 7.9% per year over this time.

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. Strong earnings per share (EPS) growth might encourage our interest in the company despite fluctuating dividends, which is why it's great to see Northern Trust has grown its earnings per share at 17% per annum over the past five years. A company paying out less than a quarter of its earnings as dividends, and growing earnings at more than 10% per annum, looks to be right in the cusp of its growth phase. At the right price, we might be interested.

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. Firstly, we like that Northern Trust has a low and conservative payout ratio. That said, we were glad to see it growing earnings and paying a fairly consistent dividend.
