What is 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'.
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 California Water Service Group:

When considering ROCE, bear in mind that it reflects the past and does not necessarily predict the future. ROCE can be deceptive for cyclical businesses, as returns can look incredible in boom times, and terribly low in downturns. This is because ROCE only looks at one year, instead of considering returns across a whole cycle.

What Are Current Liabilities, And How Do They Affect California Water Service Group's 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 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.
California Water Service Group has total assets of US$3.0b and current liabilities of US$334m. As a result, its current liabilities are equal to approximately 11% of its total assets. With a very reasonable level of current liabilities, so the impact on ROCE is fairly minimal.
