Understanding Return On Capital Employed (ROCE)

ROCE measures the amount of pre-tax profits a company can generate from the capital employed in its business. In general, businesses with a higher ROCE are usually better quality. Overall, it is a valuable metric that has its flaws. Author Edwin Whiting says to be careful when comparing the ROCE of different businesses, since 'No two businesses are exactly alike.'

How Do You Calculate Return On Capital Employed?

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 Woodside Petroleum:

0.084 = US$2.2b ÷ (US$27b - US$1.0b) (Based on the trailing twelve months to December 2018.)

Therefore, Woodside Petroleum has an ROCE of 8.4%.

Woodside Petroleum's Current Liabilities And Their Impact On Its ROCE

Current liabilities include invoices, such as supplier payments, short-term debt, or a tax bill, that need to be paid within 12 months. 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 counteract this, we check if a company has high current liabilities, relative to its total assets.

Woodside Petroleum has total liabilities of US$1.0b and total assets of US$27b. As a result, its current liabilities are equal to approximately 3.9% of its total assets. With low levels of current liabilities, at least Woodside Petroleum's mediocre ROCE is not unduly boosted.
