# Can China Nonferrous Mining Corporation Limited (HKG:1258) Maintain Its Strong Returns?

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 China Nonferrous Mining Corporation Limited (HKG:1258), by way of a worked example.

Over the last twelve months China Nonferrous Mining has recorded a ROE of 14%. That means that for every HK\$1 worth of shareholders' equity, it generated HK\$0.14 in profit.

### How Do I Calculate ROE?

The formula for return on equity is:

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

Or for China Nonferrous Mining:

14% = US\$199m Ã· US\$1.4b (Based on the trailing twelve months to June 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. You can calculate shareholders' equity by subtracting the company's total liabilities from its 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 profit over the last twelve months. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.

### Does China Nonferrous Mining Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, China Nonferrous Mining has a superior ROE than the average (8.2%) company in the Metals and Mining industry.

That's clearly a positive. 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.

### How Does Debt Impact Return On Equity?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

### Combining China Nonferrous Mining's Debt And Its 14% Return On Equity

Although China Nonferrous Mining does use debt, its debt to equity ratio of 0.89 is still low. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. 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.

### The Key Takeaway

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.

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.
