# Why You Should Like Imperial Oil Limited’s (TSE:IMO) ROCE

Today we'll evaluate Imperial Oil Limited (TSE:IMO) to determine whether it could have potential as an investment idea. Specifically, we're going to calculate its Return On Capital Employed (ROCE), in the hopes of getting some insight into the business.

First, we'll go over how we calculate ROCE. Next, we'll compare it to others in its industry. Then we'll determine how its current liabilities are affecting its ROCE.

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

ROCE measures the amount of pre-tax profits a company can generate from the 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. 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 Imperial Oil:

0.087 = CA\$3.3b ÷ (CA\$42b - CA\$4.2b) (Based on the trailing twelve months to June 2019.)

Therefore, Imperial Oil has an ROCE of 8.7%.

### Is Imperial Oil's ROCE Good?

ROCE is commonly used for comparing the performance of similar businesses. Using our data, we find that Imperial Oil's ROCE is meaningfully better than the 5.6% average in the Oil and Gas industry. We would consider this a positive, as it suggests it is using capital more effectively than other similar companies. Aside from the industry comparison, Imperial Oil'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.

In our analysis, Imperial Oil's ROCE appears to be 8.7%, compared to 3 years ago, when its ROCE was 0.8%. This makes us think about whether the company has been reinvesting shrewdly.

When considering ROCE, bear in mind that it reflects the past and does not necessarily predict the future. 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. Remember that most companies like Imperial Oil are cyclical businesses. Future performance is what matters, and you can see analyst predictions in our free report on analyst forecasts for the company.

### What Are Current Liabilities, And How Do They Affect Imperial Oil's ROCE?

Short term (or current) liabilities, are things like supplier invoices, overdrafts, or tax bills 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 check the impact of this, we calculate if a company has high current liabilities relative to its total assets.

Imperial Oil has total assets of CA\$42b and current liabilities of CA\$4.2b. Therefore its current liabilities are equivalent to approximately 10% of its total assets. It is good to see a restrained amount of current liabilities, as this limits the effect on ROCE.
