Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Basic income (loss) per share is calculated by dividing net income (loss) by the weighted-average number of shares outstanding during the period. Diluted income per share adjusts the basic income per share for the effects of any potentially dilutive instruments, only in periods in which the Company has net income and such effects are dilutive under the treasury stock method. Basic and diluted income (loss) per share is calculated using unrounded numbers. The Company reported a net loss for the three months ended December 31, 2016. Accordingly, all common stock equivalents were excluded from the computation of diluted loss per share because inclusion would have resulted in anti-dilution. For the three months ended December 31, 2016 and 2015, 1.5 million and 1.2 million shares, respectively, related to nonvested stock-based compensation awards were excluded from our calculation of diluted income per share as a result of their anti-dilutive effect. The weighted average number of common shares outstanding used to calculate basic income (loss) per share is reconciled to shares used to calculate diluted income (loss) per share as follows for the periods presented:
|  | Three Months Ended December 31,
(In thousands) |  | 2016 |  | 2015
Basic shares |  | 31,893 |  |  | 31,757 |
Shares issuable upon vesting/exercise of stock awards/options |  | — |  |  | 87 |
Diluted shares |  | 31,893 |  |  | 31,844 |
