# What Can We Make Of Smith & Nephew plc’s (LON:SN.) High Return On Capital?

Today we'll look at Smith & Nephew plc (LON:SN.) and reflect on its potential as an investment. Specifically, we're going to calculate its Return On Capital Employed (ROCE), in the hopes of getting some insight into the business.

First up, we'll look at what ROCE is and how we calculate it. Then we'll compare its ROCE to similar companies. Last but not least, we'll look at what impact its current liabilities have on its ROCE.

### Understanding Return On Capital Employed (ROCE)

ROCE is a measure of a company's yearly pre-tax profit (its return), relative to the capital employed in the business. In general, businesses with a higher ROCE are usually better quality. In brief, it is a useful tool, but it is not without drawbacks. Renowned investment researcher Michael Mauboussin has suggested that a high ROCE can indicate that 'one dollar invested in the company generates value of more than one dollar'.

### So, How Do We Calculate ROCE?

The formula for calculating the return on capital employed is:

Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)

Or for Smith & Nephew:

0.14 = US\$1.0b ÷ (US\$8.9b - US\$1.5b) (Based on the trailing twelve months to June 2019.)

So, Smith & Nephew has an ROCE of 14%.

Remember that this metric is backwards looking - it shows what has happened in the past, and does not accurately predict the future. Companies in cyclical industries can be difficult to understand using ROCE, as returns typically look high during boom times, and low during busts. ROCE is, after all, simply a snap shot of a single year. Future performance is what matters, and you can see analyst predictions in our free report on analyst forecasts for the company.

### How Smith & Nephew's Current Liabilities Impact Its ROCE

Liabilities, such as supplier bills and bank overdrafts, are referred to as current liabilities if they need to be paid within 12 months. Due to the way ROCE is calculated, a high level of current liabilities makes a company look as though it has less capital employed, and thus can (sometimes unfairly) boost the ROCE. To counteract this, we check if a company has high current liabilities, relative to its total assets.

Smith & Nephew has total assets of US\$8.9b and current liabilities of US\$1.5b. As a result, its current liabilities are equal to approximately 16% of its total assets. A fairly low level of current liabilities is not influencing the ROCE too much.
