On June 30, 2016, the Company had stock options outstanding under its 2006 Incentive Compensation Plan and stock options, stock awards and stock appreciation rights (SARs) outstanding under its 2011 Incentive Compensation Plan.

(In thousands) |
Three Months Ended June 30 |  |  | Six Months Ended June 30 |
2016 |  |  | 2015 |  |  | 2016 |  |  | 2015 |
$ | 2,025 |  |  | $ | 2,364 |  |  | $ | 4,448 |  |  | $ | 3,162 |
The increase in stock-based compensation expense between the six-month periods ended June 30, 2016 and 2015, was primarily attributable to increased compensation related to performance awards. The increase resulted from management’s assessment that the profitability performance metrics for certain grants would be achieved at greater levels than previously estimated. Unrecognized compensation costs for stock options, stock awards and SARs were as follows:
(In thousands) |  | June 30, 2016 |  |  | December 31, 2015 |
Stock options |  | $ | 1,564 |  |  | $ | 784 |
Stock awards |  |  | 5,704 |  |  |  | 3,396 |
SARs |  |  | 3,260 |  |  |  | 1,644 |
The increases in unrecognized compensation costs for stock options, stock awards and SARs reflected the 2016 grants of:
|  | Shares |
Stock options |  |  | 104,226 |
Stock awards (at target) |  |  | 72,997 |
SARs |  |  | 214,164 |
The unrecognized compensation costs at June 30, 2016, are expected to be recognized over weighted-average periods of 1.4 years, 2.1 years and 1.4 years for stock options, stock awards and SARs, respectively.
