Today we’ll look at Mueller Water Products, Inc. (NYSE:MWA) and reflect on its potential as an investment. Specifically, we’ll consider its Return On Capital Employed (ROCE), since that will give us an insight into how efficiently the business can generate profits from the capital it requires.

First of all, we’ll work out how to calculate ROCE. Second, we’ll look at its ROCE compared to similar companies. Finally, we’ll look at how its current liabilities affect its ROCE.

### Return On Capital Employed (ROCE): What is it?

ROCE is a metric for evaluating how much pre-tax income (in percentage terms) a company earns on the capital invested in its business. All else being equal, a better business will have a higher ROCE. 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’.

### How Do You Calculate Return On Capital Employed?

Analysts use this formula to calculate return on capital employed:

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

Or for Mueller Water Products:

0.11 = US\$116m ÷ (US\$1.3b – US\$169m) (Based on the trailing twelve months to December 2018.)

Therefore, Mueller Water Products has an ROCE of 11%.

### Does Mueller Water Products Have A Good ROCE?

One way to assess ROCE is to compare similar companies. It appears that Mueller Water Products’s ROCE is fairly close to the Machinery industry average of 12%. Separate from Mueller Water Products’s performance relative to its industry, its ROCE in absolute terms looks satisfactory, and it may be worth researching in more depth.

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. This is because ROCE only looks at one year, instead of considering returns across a whole cycle. Future performance is what matters, and you can see analyst predictions in our free report on analyst forecasts for the company.

### Mueller Water Products’s Current Liabilities And Their Impact On Its ROCE

Current liabilities are short term bills and invoices that need to be paid in 12 months or less. The ROCE equation subtracts current liabilities from capital employed, so a company with a lot of current liabilities appears to have less capital employed, and a higher ROCE than otherwise. To check the impact of this, we calculate if a company has high current liabilities relative to its total assets.

Mueller Water Products has total liabilities of US\$169m and total assets of US\$1.3b. Therefore its current liabilities are equivalent to approximately 13% of its total assets. Low current liabilities are not boosting the ROCE too much.
