(1) These shares of common stock were issued pursuant to an award of performance-based restricted stock units granted March 30, 2016, which vested based upon satisfaction of certain performance criteria for the three-year performance period ended March 30, 2019.
(2) Represents shares withheld to satisfy the tax obligations associated with the vesting of performance-based restricted stock units.
(3) Each performance-based restricted stock unit represents a contingent right to receive one share of the Issuer's common stock. The performance-based units vested on the Issuer's total shareholder return, determined at the three-year period ended on March 30, 2019.
(4) As a result of the Company's satisfaction of certain performance criteria for the three-year period ended March 30, 2019, the reporting person vested in 150.50% of the original grant of 28,500 performance-based restricted stock units granted on March 30, 2016, as adjusted for dividends paid on the Issuer's common stock since that date.
(5) The number of performance-based restricted stock units reflects the addition of 6,062 performance-based restricted stock units to the reporting person's initial grant as an adjustment in order to preserve the intrinsic value of the performance-based restricted stock units following the Issuer's separation of its GoTo business, as reported in the Issuer's Annual Report on Form 10-K for the fiscal year ended December 31, 2017.
