Earnings Per Share | Earnings per share for the three-month periods ended March 31, 2016 and 2015 were calculated using the weighted average number of shares outstanding for the related period. The following table reconciles the number of shares used in the computations of basic and diluted earnings per share for the three-month periods ended March 30, 2016 and 2015:
|  |  | Three Months Ended
|  |  | March 31,
|  |  | 2016 |  |  |  | 2015
|  |  | (In thousands)
Weighted average number of common shares outstanding during the period used to compute basic earnings per share |  |  | 25,296 |  |  |  | 25,635
Incremental common shares attributable to exercise of outstanding options and warrants |  |  | 4,858 |  |  |  | 6,356
Weighted average number of common shares used to compute diluted earnings per share |  |  | 30,154 |  |  |  | 31,991
If the anti-dilutive effects of common stock equivalents were considered, shares included in the diluted earnings per share calculation for the three-month periods ended March 31, 2016 and 2015 would have included an additional 6.8 million and 4.7 million shares, respectively attributable to the exercise of outstanding options and warrants.
