# Does Qualstar Corporation’s (NASDAQ:QBAK) ROCE Reflect Well On The Business?

Today we'll evaluate Qualstar Corporation (NASDAQ:QBAK) to determine whether it could have potential as an investment idea. To be precise, we'll consider its Return On Capital Employed (ROCE), as that will inform our view of the quality of the business.

First, 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.

### 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. Generally speaking a higher ROCE is better. 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'.

### 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 Qualstar:

0.094 = US\$725k ÷ (US\$11m - US\$2.9m) (Based on the trailing twelve months to June 2019.)

So, Qualstar has an ROCE of 9.4%.

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. ROCE is, after all, simply a snap shot of a single year.

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

Qualstar has total assets of US\$11m and current liabilities of US\$2.9m. Therefore its current liabilities are equivalent to approximately 28% of its total assets. It is good to see a restrained amount of current liabilities, as this limits the effect on ROCE.
