On February 4, 2014, the reporting person was granted a target of 32,831 shares of restricted stock units subject to satisfaction of pre-determined, performance-based vesting criteria. On February 2, 2016, the Company's Board of Directors determined that those performance criteria for the restricted stock units had been satisfied, which resulted in 57,453 additional shares being achieved and granted to the reporting person. Of the restricted stock units that were awarded, 45,143 will vest immediately and 45,141 will vest quarterly in the next two years.
The reported sales were to cover taxes upon the vesting of restricted stock units, as required by the Company's equity incentive plans.
