What is Return On Capital Employed (ROCE)?

ROCE is a measure of a company’s yearly pre-tax profit (its return), relative to the capital employed in the business. All else being equal, a better business will have a higher ROCE. 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?

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 Immunodiagnostic Systems Holdings:

0.02 = UK£1.2m ÷ (UK£68m – UK£7.1m) (Based on the trailing twelve months to September 2019.)

Is Immunodiagnostic Systems Holdings’s ROCE Good?

One way to assess ROCE is to compare similar companies. Using our data, Immunodiagnostic Systems Holdings’s ROCE appears to be significantly below the 11% average in the Medical Equipment industry. This performance is not ideal, as it suggests the company may not be deploying its capital as effectively as some competitors.

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.

Immunodiagnostic Systems Holdings’s Current Liabilities And Their Impact On Its 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 ROCE is calculated, a high level of current liabilities makes a company look as though it has less capital employed, and thus can (sometimes unfairly) boost the ROCE. To counteract this, we check if a company has high current liabilities, relative to its total assets.

Immunodiagnostic Systems Holdings has total assets of UK£68m and current liabilities of UK£7.1m. Therefore its current liabilities are equivalent to approximately 10% of its total assets. With a very reasonable level of current liabilities, so the impact on ROCE is fairly minimal.
