Today we'll look at California Water Service Group (NYSE:CWT) and reflect on its potential as an investment. In particular, we'll consider its Return On Capital Employed (ROCE), as that can give us insight into how profitably the company is able to employ capital in its business.

First, we'll go over how we calculate ROCE. Then we'll compare its ROCE to similar companies. Finally, we'll look at how its current liabilities affect its ROCE.

What is Return On Capital Employed (ROCE)?

ROCE measures the 'return' (pre-tax profit) a company generates from capital employed 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. Author Edwin Whiting says to be careful when comparing the ROCE of different businesses, since 'No two businesses are exactly alike.'

So, How Do We Calculate ROCE?

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 California Water Service Group:

0.043 = US$109m ÷ (US$2.9b - US$384m) (Based on the trailing twelve months to March 2019.)

So, California Water Service Group has an ROCE of 4.3%.

When considering this metric, keep in mind that it is backwards looking, and not necessarily predictive. ROCE can be misleading for companies in cyclical industries, with returns looking impressive during the boom times, but very weak during the busts. ROCE is, after all, simply a snap shot of a single year. What happens in the future is pretty important for investors, so we have prepared a free report on analyst forecasts for California Water Service Group.

How California Water Service Group's Current Liabilities Impact Its ROCE

Short term (or current) liabilities, are things like supplier invoices, overdrafts, or tax bills 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 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$2.9b and current liabilities of US$384m. As a result, its current liabilities are equal to approximately 13% of its total assets. This is not a high level of current liabilities, which would not boost the ROCE by much.
