Breaking down Return on Equity

Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. It essentially shows how much the company can generate in earnings given the amount of equity it has raised. 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

ROE is assessed against cost of equity, which is measured using the Capital Asset Pricing Model (CAPM) – but let’s not dive into the details of that today. For now, let’s just look at the cost of equity number for East West Bancorp, which is 9.96%. This means East West Bancorp returns enough to cover its own cost of equity, with a buffer of 3.19%. This sustainable practice implies that the company pays less for its capital than what it generates in return. ROE can be split up into three useful 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 reveals how much revenue can be generated from East West Bancorp’s asset base. The most interesting ratio, and reflective of sustainability of its ROE, is financial leverage. Since financial leverage can artificially inflate ROE, we need to look at how much debt East West Bancorp currently has. Currently the debt-to-equity ratio stands at a low 16.54%, which means its above-average ROE is driven by its ability to grow its profit without a significant debt burden.
