(1) The sale reported in this Form 4 was effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on July 15, 2015 and represents shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of RSUs. 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.
(2) The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices within the range of $49.5000 to $50.4999, inclusive. The Reporting Person undertakes to Workday, Inc., any security holder of Workday, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range(s) set forth in this footnote of this Form 4.
(3) Includes 225,968 RSUs that entitle the Reporting Person to receive one share of Class A Common Stock upon settlement, which will take place within 30 days of vesting, of which i) 12.5% of 81,989 RSUs granted vested or will vest in quarterly installments beginning 11/15/2015, ii) 69,738 of the RSUs will vest in eight (8) quarterly installments beginning 07/15/2016, iii) 69,738 RSUs will vest quarterly over four years with a one year cliff, and iv) 25,000 RSUs will vest quarterly over four years with a one year cliff. All grants are subject to the Reporting Person's continued employment with the Issuer on the applicable vesting date.
(4) Each share of Class B Common Stock is convertible, at any time at the option of the holder, into one (1) share of Class A Common Stock. In addition, each share of Class B Common Stock will convert automatically into one (1) share of Class A Common Stock upon any transfer, whether or not for value, except for certain permitted transfers described in, and transfers to any "permitted transferee" as defined in, the Issuer's restated certificate of incorporation in effect as of the date hereof. The shares of Class B Common Stock have no expiration date.
(5) All shares of Class A and Class B Common Stock will convert automatically into shares of a single class of Common Stock upon the earliest to occur of the following: (a) upon the election by the holders of a majority of the then outstanding shares of Class B Common Stock, (b) the date when the number of outstanding shares of Class B Common Stock represents less than 9% of all outstanding shares of Class A and Class B Common Stock, (c) October 11, 2032 or (d) nine (9) months after the death of the later to die of David A. Duffield and Aneel Bhusri. The shares of Class A and Class B Common Stock have no expiration date.
