( 1 )Consists of shares acquired in a pro rata distribution by Liberty Interactive Corporation ("Liberty") on July 22, 2016 in connection with the spin-off of the Issuer (formerly a wholly owned subsidiary of Liberty) from Liberty (the "spin-off"). ( 2 )This stock option was granted as a result of the adjustments described in this footnote. In connection with the completion of the spin-off, all option awards held by the reporting person with respect to Liberty's Liberty Ventures common stock (each, a "Pre-CH Spin Ventures Award") were adjusted pursuant to the anti-dilution provisions of the incentive plan under which the option awards were granted, such that the reporting person received (i) an adjustment to the exercise price and number of shares relating to the Pre-CH Spin Ventures Award and (ii) an option relating to shares of the corresponding series of the Issuer's common stock and an option to purchase shares of the Issuer's Series C common stock. These adjustments were approved by the Issuer's board of directors pursuant to Rule 16b-3 under the Securities Exchange Act of 1934, as amended.
