Regular readers will know that we love our dividends at Simply Wall St, which is why it's exciting to see Tai Sin Electric Limited (SGX:500) is about to trade ex-dividend in the next 4 days. The ex-dividend date is one business day before a company's record date, which is the date on which the company determines which shareholders are entitled to receive a dividend. It is important to be aware of the ex-dividend date because any trade on the stock needs to have been settled on or before the record date. Accordingly, Tai Sin Electric investors that purchase the stock on or after the 4th of March will not receive the dividend, which will be paid on the 13th of March.

The company's next dividend payment will be S$0.0075 per share, and in the last 12 months, the company paid a total of S$0.023 per share. Based on the last year's worth of payments, Tai Sin Electric stock has a trailing yield of around 5.9% on the current share price of S$0.40. If you buy this business for its dividend, you should have an idea of whether Tai Sin Electric's dividend is reliable and sustainable. So we need to check whether the dividend payments are covered, and if earnings are growing.

Dividends are typically paid out of company income, so if a company pays out more than it earned, its dividend is usually at a higher risk of being cut. Tai Sin Electric paid out 65% of its earnings to investors last year, a normal payout level for most businesses. That said, even highly profitable companies sometimes might not generate enough cash to pay the dividend, which is why we should always check if the dividend is covered by cash flow. It paid out more than half (65%) of its free cash flow in the past year, which is within an average range for most companies.

It's encouraging to see that the dividend is covered by both profit and cash flow. This generally suggests the dividend is sustainable, as long as earnings don't drop precipitously.

Have Earnings And Dividends Been Growing?

When earnings decline, dividend companies become much harder to analyse and own safely. If business enters a downturn and the dividend is cut, the company could see its value fall precipitously. With that in mind, we're discomforted by Tai Sin Electric's 6.5% per annum decline in earnings in the past five years. Such a sharp decline casts doubt on the future sustainability of the dividend.

Many investors will assess a company's dividend performance by evaluating how much the dividend payments have changed over time. Tai Sin Electric's dividend payments are broadly unchanged compared to where they were 10 years ago. If a company's dividend stays flat while earnings are in decline, this is typically a sign that it is paying out a larger percentage of its earnings. This can become unsustainable if earnings fall far enough.

The Bottom Line

Is Tai Sin Electric an attractive dividend stock, or better left on the shelf? It's never good to see earnings per share shrinking, but at least the dividend payout ratios appear reasonable. We're aware though that if earnings continue to decline, the dividend could be at risk. Bottom line: Tai Sin Electric has some unfortunate characteristics that we think could lead to sub-optimal outcomes for dividend investors.
