Explanation of Responses:
(1)	The reporting person is a trustee of the trust that owns the reported securities, but he is not a beneficiary of such trust. The reporting person disclaims beneficial ownership of the reported securities.
(2)	The reporting person disclaims beneficial ownership of the reported securities.
(3)	This transaction is a private sale and purchase between the Trusts for Children and the reporting person, in which the Trusts for Children are selling shares of Common Stock to the reporting person for the equivalent value of Graham Holdings Company Class A Common Stock, with fractional shares of Graham Holdings Company Class A being settled in cash. The reporting person has indirect beneficial ownership of the Trusts for Children, and as such this is a change in form of beneficial ownership.
(4)	The reporting person agreed to complete this transaction on July 24, 2017 as part of a larger transaction that was reported on July 26, 2017. However, due to a processing error at the bank, this transaction was not completed until July 28, 2017. For that reason, the value of Common Stock for the purpose of this transaction is based on the mean of the high and the low price of Common Stock on July 24, 2017 and the value of Graham Holdings Company Class A Common Stock is based on the mean of the high and the low price of Graham Holdings Company Class B Common Stock on July 24, 2017.
