# Are Air Canada’s (TSE:AC) Returns Worth Your While?

Today we'll look at Air Canada (TSE:AC) 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. Next, we'll compare it to others in its industry. Finally, we'll look at how its current liabilities affect its ROCE.

### Understanding 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. All else being equal, a better business will have a higher ROCE. 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'.

### How Do You Calculate Return On Capital Employed?

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 Air Canada:

0.081 = CA\$1.6b ÷ (CA\$28b - CA\$7.8b) (Based on the trailing twelve months to December 2019.)

Therefore, Air Canada has an ROCE of 8.1%.

### Is Air Canada's ROCE Good?

ROCE can be useful when making comparisons, such as between similar companies. It appears that Air Canada's ROCE is fairly close to the Airlines industry average of 10.0%. Aside from the industry comparison, Air Canada's ROCE is mediocre in absolute terms, considering the risk of investing in stocks versus the safety of a bank account. It is possible that there are more rewarding investments out there.

Air Canada's current ROCE of 8.1% is lower than its ROCE in the past, which was 13%, 3 years ago. So investors might consider if it has had issues recently. The image below shows how Air Canada's ROCE compares to its industry, and you can click it to see more detail on its past growth.

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

### How Air Canada's Current Liabilities Impact Its ROCE

Liabilities, such as supplier bills and bank overdrafts, are referred to as current liabilities if they need to be paid within 12 months. Due to the way ROCE is calculated, a high level of current liabilities makes a company look as though it has less capital employed, and thus can (sometimes unfairly) boost the ROCE. To counter this, investors can check if a company has high current liabilities relative to total assets.

Air Canada has current liabilities of CA\$7.8b and total assets of CA\$28b. As a result, its current liabilities are equal to approximately 28% of its total assets. This is a modest level of current liabilities, which would only have a small effect on ROCE.
