# Is PetroChina Company Limited’s (HKG:857) 6.4% Return On Capital Employed Good News?

Today we'll look at PetroChina Company Limited (HKG:857) and reflect on its potential as an investment. Specifically, we'll consider its Return On Capital Employed (ROCE), since that will give us an insight into how efficiently the business can generate profits from the capital it requires.

Firstly, we'll go over how we calculate ROCE. Next, we'll compare it to others in its industry. Last but not least, we'll look at what impact its current liabilities have on its ROCE.

### Understanding Return On Capital Employed (ROCE)

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. 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 PetroChina:

0.064 = CN¥131b ÷ (CN¥2.7t - CN¥649b) (Based on the trailing twelve months to September 2019.)

So, PetroChina has an ROCE of 6.4%.

When considering ROCE, bear in mind that it reflects the past and does not necessarily predict the future. ROCE can be misleading for companies in cyclical industries, with returns looking impressive during the boom times, but very weak during the busts. ROCE is only a point-in-time measure. Remember that most companies like PetroChina 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 PetroChina'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. 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.

PetroChina has current liabilities of CN¥649b and total assets of CN¥2.7t. As a result, its current liabilities are equal to approximately 24% of its total assets. This very reasonable level of current liabilities would not boost the ROCE by much.
