In light of the performance-based vesting criteria of the RSUs, such shares were not previously reportable under Section 16. Each RSU represents the contingent right to receive one share of common stock of the Issuer.

F2: Represents the sale of shares of Class A common stock to satisfy the Reporting Person's tax withholding obligations in connection with (i) the non-reportable service-based vesting and settlement of restricted stock units and (ii) the performance-based vesting and settlement of the above-listed RSUs.

F3: The price reported is a weighted average sales price. The shares were sold in multiple transactions at prices ranging from $285.38 to $286.02, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer or the staff of the Securities Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in this footnote.
