# Here’s What Plexus Corp.’s (NASDAQ:PLXS) Return On Capital Can Tell Us

Today we are going to look at Plexus Corp. (NASDAQ:PLXS) to see whether it might be an attractive investment prospect. 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.

First, we'll go over how we calculate ROCE. Then we'll compare its ROCE to similar companies. Then we'll determine how its current liabilities are affecting its ROCE.

### What is Return On Capital Employed (ROCE)?

ROCE measures the 'return' (pre-tax profit) a company generates from 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 Plexus:

0.12 = US\$141m ÷ (US\$2.0b - US\$876m) (Based on the trailing twelve months to June 2019.)

Therefore, Plexus has an ROCE of 12%.

### Is Plexus's ROCE Good?

One way to assess ROCE is to compare similar companies. Using our data, Plexus's ROCE appears to be around the 12% average of the Electronic industry.

When considering ROCE, bear in mind that it reflects the past and does not necessarily predict the future. ROCE can be misleading for companies in cyclical industries, with returns looking impressive during the boom times, but very weak during the busts. ROCE is only a point-in-time measure. Future performance is what matters, and you can see analyst predictions in our free report on analyst forecasts for the company.

### How Plexus's Current Liabilities Impact Its ROCE

Current liabilities are short term bills and invoices that need to be paid in 12 months or less. 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 check the impact of this, we calculate if a company has high current liabilities relative to its total assets.

Plexus has total assets of US\$2.0b and current liabilities of US\$876m. As a result, its current liabilities are equal to approximately 43% of its total assets. With this level of current liabilities, Plexus's ROCE is boosted somewhat.

### Our Take On Plexus's ROCE

With a decent ROCE, the company could be interesting, but remember that the level of current liabilities make the ROCE look better.
