In this article:

Today we'll look at London Security plc (LON:LSC) 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 of all, we'll work out how to calculate ROCE. Second, we'll look at its ROCE compared to similar companies. Then we'll determine how its current liabilities are affecting its ROCE.

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. Generally speaking a higher ROCE is better. 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.

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 London Security:

0.18 = UK£24m ÷ (UK£159m - UK£28m) (Based on the trailing twelve months to June 2019.)

Therefore, London Security has an ROCE of 18%.

London Security's Current Liabilities And Their Impact On Its 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.

London Security has total assets of UK£159m and current liabilities of UK£28m. As a result, its current liabilities are equal to approximately 18% of its total assets. Low current liabilities are not boosting the ROCE too much.
