PE Ratio without NRI
View All TermsP/E ratio can be affected by non-recurring-items such as the sale of part of businesses. This may increase for the current year or quarter dramatically. But it cannot be repeated over and over. Therefore P/E (NRI) is a more accurate indication of valuation than P/E (ttm).
It is calculated as:
P/E (NRI) Ratio = Share Price / {Earnings per share without Non-Recurring Items}
There are at least three kinds of P/E ratios used by different investors. They are Trailing Twelve Month P/E Ratio or P/E (ttm), forward P/E, or P/E (NRI). A new P/E ratio based on inflation-adjusted normalized P/E ratio is called {Shiller P/E}, after Yale professor Robert Shiller.
In the case of P/E (NRI), the reported earnings less the non-recurring items are used.
In the calculation of P/E (ttm), the earnings per share used are the earnings per share over the past 12 months.
For Forward P/E, the earnings are the expected earnings for the next twelve months.
For the Shiller P/E, the earnings of the past 10 years are inflation-adjusted and averaged. The result is used for P/E calculation. Since it looks at the average over the last 10 years, Shiller P/E is also called PE10.
