( 2 )Includes adjustments for dividends accrued.
( 3 )Represents award of restricted stock units (RSUs) that may be settled only for shares of common stock on a one-for-one basis. The RSUs will vest on December 31, 2020, subject to continued employment through such date. During the vesting period, an amount equal to the dividends that would have been paid on the RSU's had they been in the form of common stock will be converted into additional RSU's. The additional RSU's will also vest December 31, 2020.

This sale is mandated by the Issuer's election under its equity incentive plans to require the satisfaction of tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary trade by the reporting person.
