# What Can We Learn From Iberdrola, S.A.’s (BME:IBE) Investment Returns?

Today we are going to look at Iberdrola, S.A. (BME:IBE) to see whether it might be an attractive investment prospect. 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.

First of all, we’ll work out how to 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 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. 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?

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 Iberdrola:

0.059 = €6.0b ÷ (€119b – €18b) (Based on the trailing twelve months to September 2019.)

So, Iberdrola has an ROCE of 5.9%.

When considering this metric, keep in mind that it is backwards looking, and 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.

### What Are Current Liabilities, And How Do They Affect Iberdrola’s ROCE?

Current liabilities include invoices, such as supplier payments, short-term debt, or a tax bill, 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.

Iberdrola has total assets of €119b and current liabilities of €18b. Therefore its current liabilities are equivalent to approximately 15% of its total assets. This very reasonable level of current liabilities would not boost the ROCE by much.
