Today we'll evaluate II-VI Incorporated (NASDAQ:IIVI) to determine whether it could have potential as an investment idea. Specifically, we'll consider its Return On Capital Employed (ROCE), since that will give us an insight into how efficiently the business can generate profits from the capital it requires.

Firstly, we'll go over how we 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. Ultimately, it is a useful but imperfect metric. 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 II-VI:

0.096 = US\$163m ÷ (US\$1.9b - US\$240m) (Based on the trailing twelve months to March 2019.)

So, II-VI has an ROCE of 9.6%.

### Does II-VI Have A Good ROCE?

One way to assess ROCE is to compare similar companies. Using our data, II-VI's ROCE appears to be around the 12% average of the Electronic industry. Setting aside the industry comparison for now, II-VI's ROCE is mediocre in absolute terms, considering the risk of investing in stocks versus the safety of a bank account. Investors may wish to consider higher-performing investments.

It is important to remember that ROCE shows past performance, and is 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. This is because ROCE only looks at one year, instead of considering returns across a whole cycle. Future performance is what matters, and you can see analyst predictions in our free report on analyst forecasts for the company.

### How II-VI'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. 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 counteract this, we check if a company has high current liabilities, relative to its total assets.

II-VI has total liabilities of US\$240m and total assets of US\$1.9b. Therefore its current liabilities are equivalent to approximately 12% of its total assets. It is good to see a restrained amount of current liabilities, as this limits the effect on ROCE.
