# Should We Be Delighted With Constellation Software Inc.’s (TSE:CSU) ROE Of 39%?

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We’ll use ROE to examine Constellation Software Inc. (TSE:CSU), by way of a worked example.

Our data shows Constellation Software has a return on equity of 39% for the last year. Another way to think of that is that for every CA\$1 worth of equity in the company, it was able to earn CA\$0.39.

### How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Constellation Software:

39% = 276.36 ÷ US\$713m (Based on the trailing twelve months to September 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. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.

### What Does Return On Equity Mean?

Return on Equity measures a company’s profitability against the profit it has kept for the business (plus any capital injections). The ‘return’ is the yearly profit. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.

### Does Constellation Software Have A Good Return On Equity?

By comparing a company’s ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Constellation Software has a superior ROE than the average (8.6%) company in the Software industry.

That is a good sign. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares .

### The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won’t affect the total equity. That will make the ROE look better than if no debt was used.

### Combining Constellation Software’s Debt And Its 39% Return On Equity

While Constellation Software does have some debt, with debt to equity of just 0.56, we wouldn’t say debt is excessive. The combination of modest debt and a very impressive ROE does suggest that the business is high quality. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.

### But It’s Just One Metric

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

But when a business is high quality, the market often bids it up to a price that reflects this. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
