(1) On March 9, 2018, Liberty Interactive Corporation ("Liberty Interactive") redeemed (the "Redemption") each share of its Liberty Ventures common stock for shares of common stock of GCI Liberty, Inc. (the "Issuer"). In the Redemption, Liberty Interactive redeemed (i) each outstanding share of its Series A Liberty Ventures common stock for one share of the Issuer's Class A common stock and (ii) each outstanding share of its Series B Liberty Ventures common stock for one share of the Issuer's Class B common stock.
(2) Includes an award of 7,422 restricted shares which vests in two equal installments on December 31, 2019 and December 31, 2020.
(3) The number of shares reported as held in the reporting person's 401(k) is based on a statement from the Plan Administrator dated as of February 28, 2018, pro forma for the completion of the Redemption.
(4) In connection with the completion of the Redemption, all option awards held by the reporting person with respect to Liberty Interactive's Liberty Ventures common stock (each, a "Ventures Award") were adjusted pursuant to the anti-dilution provisions of the incentive plan under which the option awards were granted, such that each Ventures Award was exchanged for an option to purchase an equivalent number of shares of the corresponding class of the Issuer's 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.
(5) The derivative security is fully vested.
(6) The derivative security vests in two equal installments on December 31, 2019 and December 31, 2020.
