# Is MDU Resources Group Inc’s (NYSE:MDU) 12% ROE Strong Compared To Its Industry?

Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We’ll use ROE to examine MDU Resources Group Inc (NYSE:MDU), by way of a worked example.

Over the last twelve months MDU Resources Group has recorded a ROE of 12%. One way to conceptualize this, is that for each \$1 of shareholders’ equity it has, the company made \$0.12 in profit.

### How Do You Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for MDU Resources Group:

12% = US\$291m ÷ US\$2.5b (Based on the trailing twelve months to June 2018.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.

### What Does Return On Equity Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the amount earned after tax over the last twelve months. A higher profit will lead to a a higher ROE. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.

### Does MDU Resources Group Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. The image below shows that MDU Resources Group has an ROE that is roughly in line with the integrated utilities industry average (11%).

That’s neither particularly good, nor bad. Generally it will take a while for decisions made by leadership to impact the ROE. So I like to check the tenure of the board and CEO, before reaching any conclusions.

### The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

### MDU Resources Group’s Debt And Its 12% ROE

MDU Resources Group has a debt to equity ratio of 0.76, which is far from excessive. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.

### The Bottom Line On ROE

Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.

Having said that, while ROE is a useful indicator of business quality, you’ll have to look at a whole range of factors to determine the right price to buy a stock. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
