Peeling the layers of ROE – trisecting a company’s profitability
Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. An ROE of 8.07% implies HK$0.08 returned on every HK$1 invested. Generally speaking, a higher ROE is preferred; however, there are other factors we must also consider before making any conclusions.
Return on Equity = Net Profit ÷ Shareholders Equity
Returns are usually compared to costs to measure the efficiency of capital. Yanzhou Coal Mining’s cost of equity is 16.56%. This means Yanzhou Coal Mining’s returns actually do not cover its own cost of equity, with a discrepancy of -8.50%. This isn’t sustainable as it implies, very simply, that the company pays more for its capital than what it generates in return. ROE can be broken down into three different ratios: net profit margin, asset turnover, and financial leverage. This is called the Dupont Formula:
Dupont Formula
ROE = profit margin × asset turnover × financial leverage
ROE = (annual net profit ÷ sales) × (sales ÷ assets) × (assets ÷ shareholders’ equity)
ROE = annual net profit ÷ shareholders’ equity
Basically, profit margin measures how much of revenue trickles down into earnings which illustrates how efficient the business is with its cost management. Asset turnover shows how much revenue Yanzhou Coal Mining can generate with its current asset base. And finally, financial leverage is simply how much of assets are funded by equity, which exhibits how sustainable the company’s capital structure is. Since financial leverage can artificially inflate ROE, we need to look at how much debt Yanzhou Coal Mining currently has. The debt-to-equity ratio currently stands at a balanced 101.78%, meaning the ROE is a result of its capacity to produce profit growth without a huge debt burden.
Next Steps:
ROE is one of many ratios which meaningfully dissects financial statements, which illustrates the quality of a company. Yanzhou Coal Mining exhibits a weak ROE against its peers, as well as insufficient levels to cover its own cost of equity this year. However, ROE is not likely to be inflated by excessive debt funding, giving shareholders more conviction in the sustainability of returns, which has headroom to increase further. Although ROE can be a useful metric, it is only a small part of diligent research.
