Earnings Per Share [Abstract] |
Earnings Per Share | NOTE 4: EARNINGS PER SHARE Basic Earnings Per Share Attributable to Common Stockholders We compute basic earnings per share (“Basic EPS”) by dividing net income by the weighted average number of common shares outstanding during the period. We compute the weighted average number of common shares outstanding during the reporting period using the total of common stock and Class B common stock outstanding as of the last day of the previous year end reporting period plus the weighted average of any additional shares issued and outstanding less the weighted average of any treasury shares repurchased during the reporting period. Diluted Earnings Per Share Attributable to Common Stockholders We compute diluted earnings per share (“Diluted EPS”) by dividing net income by the sum of the weighted average number of common and common equivalent shares outstanding during the period. We computed the weighted average number of common and common equivalent shares outstanding during the period using the sum of (i) the number of shares of common stock and Class B common stock used in the basic earnings per share calculation as indicated above, and (ii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of outstanding common equivalent shares related to stock options and the vesting of restricted stock units using the treasury stock method, and (iii) if dilutive, performance based awards based on the number of shares that would be issuable as of the end of the reporting period assuming the end of the reporting period was also the end of the contingency period. Under the treasury stock method, the assumed proceeds calculation includes the actual proceeds to be received from the employee upon exercise, the average unrecognized compensation cost during the period and any tax benefits credited upon exercise to additional paid-in-capital. The treasury stock method assumes that a company uses the proceeds from the exercise of an award to repurchase common stock at the average market price for the period. Windfall tax benefits created upon the exercise of an award would be added to assumed proceeds, while shortfalls charged to additional paid-in-capital would be deducted from assumed proceeds. Any shortfalls not covered by the windfall tax pool would be charged to the income statement and would be excluded from the calculation of assumed proceeds, if any. Below is a reconciliation of the weighted average number of shares of common stock outstanding in calculating Diluted EPS (shares in thousands and dollars in millions, except per share amounts) for the periods presented:
|  | Three months ended June 30, |  |  | Six months ended June 30, |
|  | 2016 |  |  | 2015 |  |  | 2016 |  |  | 2015 |
Numerator: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Net income |  | $ | 34 |  |  | $ | 58 |  |  | $ | 62 |  |  | $ | 121 |
Denominator: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Weighted average shares used to compute Basic EPS |  |  | 145,732 |  |  |  | 143,709 |  |  |  | 145,588 |  |  |  | 143,427 |
Weighted average effect of dilutive securities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Stock options |  |  | 1,060 |  |  |  | 2,019 |  |  |  | 1,123 |  |  |  | 2,218 |
RSUs |  |  | 268 |  |  |  | 231 |  |  |  | 271 |  |  |  | 271 |
Weighted average shares used to compute Diluted EPS |  |  | 147,060 |  |  |  | 145,959 |  |  |  | 146,982 |  |  |  | 145,916 |
Basic EPS |  | $ | 0.23 |  |  | $ | 0.40 |  |  | $ | 0.42 |  |  | $ | 0.85 |
Diluted EPS |  | $ | 0.23 |  |  | $ | 0.40 |  |  | $ | 0.42 |  |  | $ | 0.83 |
The following potential common shares related to stock options and RSUs were excluded from the calculation of Diluted EPS (in thousands) because their effect would have been anti-dilutive for the periods presented:
|  | Three months ended June 30, |  |  | Six months ended June 30, |
|  | 2016(1) |  |  | 2015(2) |  |  | 2016(1) |  |  | 2015(2) |
Stock options |  |  | 3,055 |  |  |  | 2,107 |  |  |  | 2,963 |  |  |  | 2,124 |
RSUs |  |  | 682 |  |  |  | 745 |  |  |  | 784 |  |  |  | 793 |
Total |  |  | 3,737 |  |  |  | 2,852 |  |  |  | 3,747 |  |  |  | 2,917 |
| (1) | These totals do not include 125,000 performance based options and 12,799 performance based RSUs representing the right to acquire 137,799 shares of common stock for which all targets required to trigger vesting had not been achieved; therefore, such awards were excluded from the calculation of weighted average shares used to compute Diluted EPS for those reporting periods.
| (2) | These totals do not include 66,666 performance based options and 12,799 performance based RSUs representing the right to acquire 79,465 shares of common stock for which all targets required to trigger vesting had not been achieved; therefore, such awards were excluded from the calculation of weighted average shares used to compute Diluted EPS for those reporting periods.
The earnings per share amounts are the same for common stock and Class B common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation.
