# Should You Like A. O. Smith Corporation’s (NYSE:AOS) High Return On Capital Employed?

Today we'll evaluate A. O. Smith Corporation (NYSE:AOS) to determine whether it could have potential as an investment idea. To be precise, we'll consider its Return On Capital Employed (ROCE), as that will inform our view of the quality of 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. Then we'll determine how its current liabilities are affecting its ROCE.

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

ROCE is a metric for evaluating how much pre-tax income (in percentage terms) a company earns on the capital invested in its 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'.

### 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 A. O. Smith:

0.22 = US\$528m ÷ (US\$3.2b - US\$731m) (Based on the trailing twelve months to June 2019.)

Therefore, A. O. Smith has an ROCE of 22%.

### What Are Current Liabilities, And How Do They Affect A. O. Smith's ROCE?

Short term (or current) liabilities, are things like supplier invoices, overdrafts, or tax bills that need to be paid within 12 months. Due to the way the ROCE equation works, having large bills due in the near term can make it look as though a company has less capital employed, and thus a higher ROCE than usual. To check the impact of this, we calculate if a company has high current liabilities relative to its total assets.

A. O. Smith has total liabilities of US\$731m and total assets of US\$3.2b. Therefore its current liabilities are equivalent to approximately 23% of its total assets. A minimal amount of current liabilities limits the impact on ROCE.
