Explanation of Responses:

( 1 )Pursuant to the Split-Off (as described in the Remarks section), all of the outstanding ordinary shares of Liberty Global plc's (the "Issuer") Class A LiLAC ordinary shares, Class B LiLAC ordinary shares and Class C LiLAC ordinary shares were redesignated as deferred shares (with virtually no economic rights) and those deferred shares were transferred for no consideration to a third-party designee. The Split-Off was exempt pursuant to Rule 16b-7 under the Securities Exchange Act of 1934, as amended (the "Act"). ( 2 )In connection with the Split-Off, the SARs were converted on a one-for-one basis, pursuant to the anti-dilution provisions of the plan under which the SARs were granted, to SARs of Splitco with the same terms, conditions and share class as the Issuer's SARs. These transactions were approved by the Issuer's board of directors pursuant to Rule 16b-3 under the Act. ( 3 )The SARs provide for vesting of 12.5% of the shares on November 1, 2017, and the remaining shares in 14 equal quarterly installments commencing February 1, 2018. ( 4 )The SARs provide for vesting of 12.5% of the shares on November 1, 2016, and the remaining shares in 14 equal quarterly installments commencing February 1, 2017. ( 5 )The SARs provide for vesting of 12.5% of the shares on November 1, 2015, and the remaining shares in 14 equal quarterly installments commencing February 1, 2016. ( 6 )The SARS provide for vesting of 12.5% of the shares on November 1, 2014, and the remaining shares in 14 equal quarterly installments commencing February 1, 2015. ( 7 )The SARs are immediately exercisable.

Remarks: On December 29, 2017, the Issuer effected the split-off of its wholly owned subsidiary, Liberty Latin America Ltd. ("Splitco"), by distributing Splitco's common shares (the "distribution") to the holders of the Issuer's LiLAC Ordinary Shares. Immediately following the distribution, the LiLAC Ordinary Shares were redesignated as deferred shares (with virtually no economic rights) and those deferred shares were transferred for no consideration to a third-party designee (such transactions together with the distribution, the "Split-Off"). In the distribution, holders of LiLAC Ordinary Shares received one share of the same class of common shares of Splitco for each LiLAC Ordinary Share held by them at 5:00 p.m., New York City time, on December 29, 2017. The trading symbols for the Issuer's classes of ordinary shares are LBTYA, LBTYB and LBTYK.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
