# Should We Be Delighted With Synlait Milk Limited's (NZSE:SML) ROE Of 17%?

While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Synlait Milk Limited (NZSE:SML), by way of a worked example.

Over the last twelve months Synlait Milk has recorded a ROE of 17%. That means that for every NZ\$1 worth of shareholders' equity, it generated NZ\$0.17 in profit.

### How Do You Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) Ã· Shareholders' Equity

Or for Synlait Milk:

17% = NZ\$82m Ã· NZ\$492m (Based on the trailing twelve months to July 2019.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is the capital paid in by shareholders, plus any retained earnings. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

### What Does ROE Signify?

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 higher ROE. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.

### Does Synlait Milk Have A Good ROE?

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. As is clear from the image below, Synlait Milk has a better ROE than the average (6.9%) in the Food industry.

That's clearly a positive. I usually take a closer look when a company has a better ROE than industry peers. One data point to check is if insiders have bought shares recently.

### The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

### Combining Synlait Milk's Debt And Its 17% Return On Equity

Although Synlait Milk does use debt, its debt to equity ratio of 0.71 is still low. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. 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 one way we can compare the business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
