The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We’ll show how you can use CSR Limited’s (ASX:CSR) P/E ratio to inform your assessment of the investment opportunity. What is CSR’s P/E ratio? Well, based on the last twelve months it is 15.43. That corresponds to an earnings yield of approximately 6.5%.

### How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for CSR:

P/E of 15.43 = A\$4.26 ÷ A\$0.28 (Based on the trailing twelve months to March 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each A\$1 the company has earned over the last year. All else being equal, it’s better to pay a low price — but as Warren Buffett said, ‘It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.’

### Does CSR Have A Relatively High Or Low P/E For Its Industry?

We can get an indication of market expectations by looking at the P/E ratio. You can see in the image below that the average P/E (14.7) for companies in the basic materials industry is roughly the same as CSR’s P/E.

Its P/E ratio suggests that CSR shareholders think that in the future it will perform about the same as other companies in its industry classification.

### How Growth Rates Impact P/E Ratios

Companies that shrink earnings per share quickly will rapidly decrease the ‘E’ in the equation. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. Then, a higher P/E might scare off shareholders, pushing the share price down.

CSR’s earnings per share fell by 30% in the last twelve months. But it has grown its earnings per share by 9.6% per year over the last five years.

### Remember: P/E Ratios Don’t Consider The Balance Sheet

It’s important to note that the P/E ratio considers the market capitalization, not the enterprise value. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

While growth expenditure doesn’t always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

### How Does CSR’s Debt Impact Its P/E Ratio?

CSR has net cash of AU\$50m. That should lead to a higher P/E than if it did have debt, because its strong balance sheets gives it more options.

### The Verdict On CSR’s P/E Ratio

CSR trades on a P/E ratio of 15.4, which is fairly close to the AU market average of 16.3. While the absence of growth in the last year is probably causing a degree of pessimism, the net cash position means it’s not surprising that expectations put the company roughly in line with the market average P/E.
