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:
