Breaking down ROE — the mother of all ratios

Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. An ROE of 15.30% implies $0.15 returned on every $1 invested. While a higher ROE is preferred in most cases, there are several other factors we should consider before drawing any conclusions.

Return on Equity = Net Profit ÷ Shareholders Equity

ROE is measured against cost of equity in order to determine the efficiency of American Tower (REIT)’s equity capital deployed. Its cost of equity is 8.49%. Given a positive discrepancy of 6.81% between return and cost, this indicates that American Tower (REIT) pays less for its capital than what it generates in return, which is a sign of capital efficiency. 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

The first component is profit margin, which measures how much of sales is retained after the company pays for all its expenses. Asset turnover shows how much revenue American Tower (REIT) can generate with its current asset base. The most interesting ratio, and reflective of sustainability of its ROE, is financial leverage. Since ROE can be artificially increased through excessive borrowing, we should check American Tower (REIT)’s historic debt-to-equity ratio. The debt-to-equity ratio currently stands at a high 233.38%, meaning the above-average ratio is a result of a large amount of debt.

ROE is a simple yet informative ratio, illustrating the various components that each measure the quality of the overall stock.
