# Evaluating Aqualis ASA’s (OB:AQUA) Investments In Its Business

Today we’ll look at Aqualis ASA (OB:AQUA) 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.

Firstly, we’ll go over how we calculate ROCE. Then we’ll compare its ROCE to similar companies. Last but not least, we’ll look at what impact its current liabilities have on its ROCE.

### Understanding 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. 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?

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 Aqualis:

0.09 = US\$2.4m ÷ (US\$31m – US\$4.1m) (Based on the trailing twelve months to December 2018.)

Therefore, Aqualis has an ROCE of 9.0%.

### Does Aqualis Have A Good ROCE?

ROCE is commonly used for comparing the performance of similar businesses. We can see Aqualis’s ROCE is around the 8.3% average reported by the Energy Services industry. Separate from how Aqualis stacks up against its industry, its ROCE in absolute terms is mediocre; relative to the returns on government bonds. Investors may wish to consider higher-performing investments.

Aqualis has an ROCE of 9.0%, but it didn’t have an ROCE 3 years ago, since it was unprofitable. This makes us wonder if the company is improving.

When considering this metric, keep in mind that it is backwards looking, and not necessarily predictive. 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. Remember that most companies like Aqualis are cyclical businesses. How cyclical is Aqualis?

### Do Aqualis’s Current Liabilities Skew Its ROCE?

Current liabilities are short term bills and invoices that need to be paid in 12 months or less. 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.

Aqualis has total liabilities of US\$4.1m and total assets of US\$31m. As a result, its current liabilities are equal to approximately 13% of its total assets. This very reasonable level of current liabilities would not boost the ROCE by much.
