# What Can We Make Of Rectifier Technologies Limited’s (ASX:RFT) High Return On Capital?

Today we'll look at Rectifier Technologies Limited (ASX:RFT) 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. Next, we'll compare it to others in its industry. And finally, we'll look at how its current liabilities are impacting 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. In general, businesses with a higher ROCE are usually better quality. 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?

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 Rectifier Technologies:

0.37 = AU\$3.5m ÷ (AU\$14m - AU\$4.8m) (Based on the trailing twelve months to June 2019.)

So, Rectifier Technologies has an ROCE of 37%.

It is important to remember that ROCE shows past performance, and is not necessarily predictive. Companies in cyclical industries can be difficult to understand using ROCE, as returns typically look high during boom times, and low during busts. ROCE is only a point-in-time measure.

### Do Rectifier Technologies's Current Liabilities Skew 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 counter this, investors can check if a company has high current liabilities relative to total assets.

Rectifier Technologies has total assets of AU\$14m and current liabilities of AU\$4.8m. Therefore its current liabilities are equivalent to approximately 34% of its total assets. Rectifier Technologies has a medium level of current liabilities, boosting its ROCE somewhat.
