# Evaluating The AES Corporation’s (NYSE:AES) Investments In Its Business

Today we'll look at The AES Corporation (NYSE:AES) and reflect on its potential as an investment. 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 of all, we'll work out how to calculate ROCE. Then we'll compare its ROCE to similar companies. Last but not least, we'll look at what impact its current liabilities have on 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. 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 AES:

0.075 = US\$2.2b ÷ (US\$33b - US\$4.0b) (Based on the trailing twelve months to June 2019.)

Therefore, AES has an ROCE of 7.5%.

### Does AES Have A Good ROCE?

ROCE can be useful when making comparisons, such as between similar companies. It appears that AES's ROCE is fairly close to the Renewable Energy industry average of 6.5%. Setting aside the industry comparison for now, AES'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.

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. This is because ROCE only looks at one year, instead of considering returns across a whole cycle.

### AES's Current Liabilities And Their Impact On Its ROCE

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

AES has total assets of US\$33b and current liabilities of US\$4.0b. As a result, its current liabilities are equal to approximately 12% of its total assets. This is a modest level of current liabilities, which would only have a small effect on ROCE.
