The content of this article will benefit those of you who are starting to educate yourself about investing in the stock market and want to learn about Return on Equity using a real-life example.
Carnarvon Petroleum Limited’s (ASX:CVN) most recent return on equity was a substandard 1.2% relative to its industry performance of 10.9% over the past year. CVN’s results could indicate a relatively inefficient operation to its peers, and while this may be the case, it is important to understand what ROE is made up of and how it should be interpreted. Knowing these components could change your view on CVN’s performance. Metrics such as financial leverage can impact the level of ROE which in turn can affect the sustainability of CVN’s returns.

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. For example, if the company invests A$1 in the form of equity, it will generate A$0.012 in earnings from this. 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 Carnarvon Petroleum’s equity capital deployed. Its cost of equity is 9.3%. Given a discrepancy of -8.1% between return and cost, this indicated that Carnarvon Petroleum may be paying more for its capital than what it’s generating 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 shows how much revenue Carnarvon Petroleum 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 ROE can be inflated by excessive debt, we need to examine Carnarvon Petroleum’s debt-to-equity level. Currently, Carnarvon Petroleum has no debt which means its returns are driven purely by equity capital. This could explain why Carnarvon Petroleum’s’ ROE is lower than its industry peers, most of which may have some degree of debt in its business.
