of common stock shares outstanding over the past year; this is adjusted for dilutive shares. Some data sources may simplify this calculation by using the number of shares outstanding at the end of a reporting period. The methods of simplifying EPS calculations and eliminating inappropriate assumptions include replacing primary EPS with basic EPS, eliminating the treasury stock method of accounting from fully diluted EPS, eliminating the three-percent test for dual presentation, and providing information on individual dilative securities.


Calculations of diluted EPS under U.S. GAAP are described under Statement No. 128 of the Financial Accounting Standards Board (FAS No. 128). The objective of diluted EPS is to measure the performance of a company over the reporting period taking into account the dilutive effect of potential common stock that could be issued by the company. To compute diluted EPS, both the denominator (outstanding shares) and the numerator (earnings) may need to be adjusted. ''Diluted shares: '' To calculate the total number of shares used in the calculation, FASB prescribes using the treasury method to calculate the dilutive effect of any instruments that could result in the issuance of shares, including: * Stock options * Warrants * Convertible preferred stock * Convertible bonds * Share-based payment arrangements * Written put options * Contingently issuable shares ''Earnings: '' The numerator used in calculating diluted EPS is adjusted to take into account the impact that the conversion of any securities would have on earnings. For example, interest would be added back to earnings to reflect the conversion of any outstanding convertible bonds, preferred dividends would be added back to reflect the conversion of convertible preferred stock, and any impact of these changes on other financial items, such as royalties and taxes, would also be adjusted.
