Western Asset Mortgage Defined Opportunity Fund  (NYSE:DMO) ROA % Explanation

ROA % measures the rate of return on the total assets (shareholder equity plus liabilities). It measures a firm's efficiency at generating profits from shareholders' equity plus its liabilities. ROA % shows how well a company uses what it has to generate earnings. ROA %s can vary drastically across industries. Therefore, ROA % should not be used to compare companies in different industries. For retailers, a ROA % of higher than 5% is expected. For example, Wal-Mart (WMT) has a ROA % of about 8% as of 2012. For banks, ROA % is close to their interest spread. A bank’s ROA % is typically well under 2%.

Similar to ROE, ROA % is affected by profit margins and asset turnover. This can be seen from the Du Pont Formula:

ROA %(Q: Dec. 2025 )
=Net Income/Total Assets
=11.97/259.71
=(Net Income / Revenue)*(Revenue / Total Assets)
=(11.97 / 12.574)*(12.574 / 259.71)
=Net Margin %*Asset Turnover
=95.2 %*0.0484
=4.61 %

Note: The Net Income data used here is two times the semi-annual (Dec. 2025) net income data. The Revenue data used here is two times the semi-annual (Dec. 2025) revenue data.

Be Aware

Like ROE, ROA % is calculated with only 12 months data. Fluctuations in the company's earnings or business cycles can affect the ratio drastically. It is important to look at the ratio from a long term perspective. ROA % can be affected by events such as stock buyback or issuance, and by goodwill, a company's tax rate and its interest payment. ROA % may not reflect the true earning power of the assets. A more accurate measurement is ROC % (ROC).

Many analysts argue the higher return the better. Buffett states that really high ROA % may indicate vulnerability in the durability of the competitive advantage.

E.g. Raising $43b to take on KO is impossible, but $1.7b to take on Moody's is. Although Moody's ROA % and underlying economics is far superior to Coca Cola, the durability is far weaker because of lower entry cost.
