### Understanding Return On Capital Employed (ROCE)

ROCE measures the ‘return’ (pre-tax profit) a company generates from capital employed in its business. Generally speaking a higher ROCE is better. Overall, it is a valuable metric that has its flaws. 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?

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 Grenergy Renovables:

0.20 = €12m ÷ (€110m – €47m) (Based on the trailing twelve months to June 2019.)

When considering this metric, keep in mind that it is backwards looking, and not necessarily predictive.

### Grenergy Renovables’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. 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.

Grenergy Renovables has current liabilities of €47m and total assets of €110m. As a result, its current liabilities are equal to approximately 43% of its total assets. A medium level of current liabilities boosts Grenergy Renovables’s ROCE somewhat.
