# Here’s why China Communications Services Corporation Limited’s (HKG:552) Returns On Capital Matters So Much

Today we'll evaluate China Communications Services Corporation Limited (HKG:552) to determine whether it could have potential as an investment idea. 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.

First up, we'll look at what ROCE is and how we calculate it. Next, we'll compare it to others in its industry. And finally, we'll look at how its current liabilities are impacting its ROCE.

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

ROCE is a metric for evaluating how much pre-tax income (in percentage terms) a company earns on the capital invested in its business. All else being equal, a better business will have a higher ROCE. 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'.

### 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 China Communications Services:

0.075 = CN¥2.7b ÷ (CN¥86b - CN¥50b) (Based on the trailing twelve months to June 2019.)

Therefore, China Communications Services has an ROCE of 7.5%.

### Is China Communications Services's ROCE Good?

One way to assess ROCE is to compare similar companies. In this analysis, China Communications Services's ROCE appears meaningfully below the 12% average reported by the Construction industry. This performance could be negative if sustained, as it suggests the business may underperform its industry. Aside from the industry comparison, China Communications Services'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.

We can see that , China Communications Services currently has an ROCE of 7.5%, less than the 10.0% it reported 3 years ago. So investors might consider if it has had issues recently.

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, after all, simply a snap shot of a single year. Since the future is so important for investors, you should check out our free report on analyst forecasts for China Communications Services.

### What Are Current Liabilities, And How Do They Affect China Communications Services'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 counter this, investors can check if a company has high current liabilities relative to total assets.

China Communications Services has total liabilities of CN¥50b and total assets of CN¥86b. Therefore its current liabilities are equivalent to approximately 58% of its total assets. China Communications Services has a fairly high level of current liabilities, meaningfully impacting its ROCE.
