Earnings per share

Earnings per share (EPS) is the monetary value of earnings per outstanding share of common stock for a company. It is a key measure of corporate profitability and is commonly used to price stocks.
In the United States, the Financial Accounting Standards Board (FASB) requires EPS information for the four major categories of the income statement: continuing operations, discontinued operations, extraordinary items, and net income.
Calculation
Preferred stock rights have precedence over common stock. Therefore, dividends on preferred shares are subtracted before calculating the EPS. When preferred shares are cumulative (i.e. dividends accumulate as payable if unpaid in the given accounting year), annual dividends are deducted whether or not they have been declared. Dividends in arrears are not relevant when calculating EPS.

Diluted earnings per share
Diluted earnings per share (diluted EPS) is a company's earnings per share calculated using fully diluted shares outstanding (i.e. including the impact of stock option grants and convertible bonds). Diluted EPS indicates a "worst case" scenario, one that reflects the issuance of stock for all outstanding options, warrants and convertible securities that would reduce earnings per share.
Calculations
Calculations of diluted EPS vary. Morningstar reports diluted EPS "Earnings/Share $", which is net income minus preferred stock dividends divided by the weighted average 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.
U.S. GAAP
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.
As mentioned above, a helpful way to consider the effect of dilutive instruments on EPS is to think about the "as if" method; in the sense that "if the instrument is converted, how does it affect EPS?" For example, let Campany XYZ have Net Income = $2,000,000 , there are 50,000 shares of common stock outstanding, and $1,000,000 of 10% bonds, convertible into 50,000 shares of common stock. Company A's tax rate is 25%.
Basic EPS = ($2,000,000 - ($1,000,000*10%))/50,000 = $38
Diluted EPS = ($2,000,000 + (25%*($1,000,000*10%))) / 50,000 + 50,000 = $20.25
Note that other than accounting for the shares of common stock added in the denominator of the EPS equation, we also add back the taxes that would have been taken out from Net income if the bonds were not converted. In conclusion, the "as if" method is helpful in considering the effect on dilutive instruments on EPS because it helps us think about the overall effect rather than just thinking about the numerator and denominator of the equation separately.
International financial reporting standards
Under International Financial Reporting Standards, diluted earnings per share is calculated by adjusting the earnings and number of shares for the effects of dilutive options and other dilutive potential common stock. Dilutive potential common stock includes:
convertible debt
convertible preferred stock
share warrants
share options
share rights
Employee stock purchase plans
contractual rights to purchase shares
contingent issuance contracts or agreement
The earnings per share requirements of U.S. GAAP,FASB ASC 260: EPS, are a result of the FASB's cooperation with the IASB to narrow the difference between IFRS and US GAAP. A few differences remain.
The differences that remain are the result of differences in the application of the treasury stock method, the treament of contracts that may be settled in shares or cash, and contingently issuable shares.
