F1 · kind: As previously reported, on November 12, 2015, Liberty Global Incorporated Limited ("Liberty"), a wholly-owned subsidiary of Liberty Global plc, entered into a Variable Pre-paid Forward Transaction ("Transaction") with an unaffiliated bank ("Bank") relating to 2,500,000 common shares of the Issuer, no par value ("Common Shares"), and subsequently, pursuant to a reclassification exempt under Rule 16b-7, each Common Share was reclassified (the "Reclassification") into 0.5 Class A voting shares of the Issuer, no par value ("Class A Voting Shares"), and 0.5 Class B non-voting shares of the Issuer, no par value ("Class B Non-Voting Shares").

F2 · kind: In connection with the Reclassification, pursuant to a notice dated February 10, 2017 given by the Bank as calculation agent, the terms of the Transaction were adjusted to reflect the Reclassification with no change to the economic rights and obligations of either Liberty or the Bank. As adjusted, the Transaction relates to units consisting of 0.5 shares of the Class A Voting Shares and 0.5 shares of the Class B Non-Voting Shares.

F3 · kind: As previously reported, Liberty received a cash payment of $70,889,585.00 as of the date of entering into the Transaction. Liberty pledged 2,500,000 Common Shares to the Bank to secure its obligations under the Transaction; in connection with the Reclassification, such pledged Common Shares were replaced by a pledge by Liberty of 1,250,000 Class A Voting Shares and 1,250,000 Class B Non-Voting Shares (collectively, the "Pledged Shares"). In most circumstances, Liberty retained voting rights in the Pledged Shares during the term of the pledge, but Liberty is obligated to share with the Bank the economic benefit of any dividends paid during the term of the pledge based on a formula that takes into account a theoretical hedging position by the Bank.

F4 · kind: The Transaction is divided into three individual tranches (each a "Tranche") with each Tranche divided into 25 individual components (each a "Component") designated by a valuation date; the Components for Tranche 1 are the 25 trading days from July 25, 2019 through August 28, 2019, inclusive; the Components for Tranche 2 are the 25 trading days from October 23, 2020 through November 30, 2020, inclusive; and the Components for Tranche 3 are the 25 trading days from January 25, 2022 through March 1, 2022, inclusive.

F5 · kind: On the settlement date for each Component, Liberty will deliver to the Bank a cash equivalent of the following (unless share settlement is elected): (a) if the sum of the volume weighted average trading price per Class A Voting Share multiplied by 0.5 and the volume weighted average trading price per Class B Non-Voting Share multiplied by 0.5 on the valuation date for the relevant Component ("Settlement Price") is less than $33.167 (the "Forward Floor Price"), 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares (or, in the case of the last Component in each Tranche, (A) in the case of each of Tranche 1 and 2, 16,658.5 Class A Voting Shares and 16,658.5 Class B Non-Voting Shares, and (B) in the case of Tranche 3, 16,659 Class A Voting Shares and 16,659 Class B Non-Voting Shares) ("Number of Shares");

F6 · kind: (b) if the Settlement Price is greater than the Forward Floor Price but less than or equal to $52.677 ("Forward Cap Price"), the Number of Shares multiplied by the Forward Floor Price divided by the Settlement Price; and (c) if the Settlement Price is greater than the Forward Cap Price, the Number of Shares multiplied by (1 - ((Forward Cap Price - Forward Floor Price), divided by the Settlement Price)).

F9 · kind: On 08/09/2019, the twelfth component of Tranche 1 matured, which the Reporting Person cash settled. The Settlement Price was below the Forward Floor Price; therefore, the Reporting Person paid $415,944.99 in cash to the Bank and the Pledged Shares were reduced by 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares.

F1 · price: As previously reported, on November 12, 2015, Liberty Global Incorporated Limited ("Liberty"), a wholly-owned subsidiary of Liberty Global plc, entered into a Variable Pre-paid Forward Transaction ("Transaction") with an unaffiliated bank ("Bank") relating to 2,500,000 common shares of the Issuer, no par value ("Common Shares"), and subsequently, pursuant to a reclassification exempt under Rule 16b-7, each Common Share was reclassified (the "Reclassification") into 0.5 Class A voting shares of the Issuer, no par value ("Class A Voting Shares"), and 0.5 Class B non-voting shares of the Issuer, no par value ("Class B Non-Voting Shares").

F2 · price: In connection with the Reclassification, pursuant to a notice dated February 10, 2017 given by the Bank as calculation agent, the terms of the Transaction were adjusted to reflect the Reclassification with no change to the economic rights and obligations of either Liberty or the Bank. As adjusted, the Transaction relates to units consisting of 0.5 shares of the Class A Voting Shares and 0.5 shares of the Class B Non-Voting Shares.

F3 · price: As previously reported, Liberty received a cash payment of $70,889,585.00 as of the date of entering into the Transaction.

F5 · price: On the settlement date for each Component, Liberty will deliver to the Bank a cash equivalent of the following (unless share settlement is elected): (a) if the sum of the volume weighted average trading price per Class A Voting Share multiplied by 0.5 and the volume weighted average trading price per Class B Non-Voting Share multiplied by 0.5 on the valuation date for the relevant Component ("Settlement Price") is less than $33.167 (the "Forward Floor Price"), 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares (or, in the case of the last Component in each Tranche, (A) in the case of each of Tranche 1 and 2, 16,658.5 Class A Voting Shares and 16,658.5 Class B Non-Voting Shares, and (B) in the case of Tranche 3, 16,659 Class A Voting Shares and 16,659 Class B Non-Voting Shares) ("Number of Shares");

F6 · price: (b) if the Settlement Price is greater than the Forward Floor Price but less than or equal to $52.677 ("Forward Cap Price"), the Number of Shares multiplied by the Forward Floor Price divided by the Settlement Price; and (c) if the Settlement Price is greater than the Forward Cap Price, the Number of Shares multiplied by (1 - ((Forward Cap Price - Forward Floor Price), divided by the Settlement Price)).

F9 · price: On 08/09/2019, the twelfth component of Tranche 1 matured, which the Reporting Person cash settled. The Settlement Price was below the Forward Floor Price; therefore, the Reporting Person paid $415,944.99 in cash to the Bank and the Pledged Shares were reduced by 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares.

F7 · price: On 08/07/2019, the tenth component of Tranche 1 matured, which the Reporting Person cash settled.

F3 · kind: As previously reported, Liberty received a cash payment of $70,889,585.00 as of the date of entering into the Transaction.

In most circumstances, Liberty retained voting rights in the Pledged Shares during the term of the pledge, but Liberty is obligated to share with the Bank the economic benefit of any dividends paid during the term of the pledge based on a formula that takes into account a theoretical hedging position by the Bank.

F4 · kind: The Transaction is divided into three individual tranches (each a "Tranche") with each Tranche divided into 25 individual components (each a "Component") designated by a valuation date; the Components for Tranche 1 are the 25 trading days from July 25, 2019 through August 28, 2019, inclusive; the Components for Tranche 2 are the 25 trading days from October 23, 2020 through November 30, 2020, inclusive; and the Components for Tranche 3 are the 25 trading days from January 25, 2022 through March 1, 2022, inclusive.

F9 · kind: On 08/06/2019, the ninth component of Tranche 1 matured, which the Reporting Person cash settled. The Settlement Price was below the Forward Floor Price; therefore, the Reporting Person paid $395,117.90 in cash to the Bank and the Pledged Shares were reduced by 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares.

F2 · kind: In connection with the Reclassification, pursuant to a notice dated February 10, 2017 given by the Bank as calculation agent, the terms of the Transaction were adjusted to reflect the Reclassification with no change to the economic rights and obligations of either Liberty or the Bank.

F3 · kind: As previously reported, Liberty received a cash payment of $70,889,585.00 as of the date of entering into the Transaction.

In most circumstances, Liberty retained voting rights in the Pledged Shares during the term of the pledge, but Liberty is obligated to share with the Bank the economic benefit of any dividends paid during the term of the pledge based on a formula that takes into account a theoretical hedging position by the Bank.

F4 · kind: The Transaction is divided into three individual tranches (each a "Tranche") with each Tranche divided into 25 individual components (each a "Component") designated by a valuation date; the Components for Tranche 1 are the 25 trading days from July 25, 2019 through August 28, 2019, inclusive; the Components for Tranche 2 are the 25 trading days from October 23, 2020 through November 30, 2020, inclusive; and the Components for Tranche 3 are the 25 trading days from January 25, 2022 through March 1, 2022, inclusive.

F8 · kind: On 08/05/2019, the eighth component of Tranche 1 matured, which the Reporting Person cash settled. The Settlement Price was below the Forward Floor Price; therefore, the Reporting Person paid $404,533.09 in cash to the Bank and the Pledged Shares were reduced by 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares.

F1 · kind: As previously reported, on November 12, 2015, Liberty Global Incorporated Limited ("Liberty"), a wholly-owned subsidiary of Liberty Global plc, entered into a Variable Pre-paid Forward Transaction ("Transaction") with an unaffiliated bank ("Bank") relating to 2,500,000 common shares of the Issuer, no par value ("Common Shares"), and subsequently, pursuant to a reclassification exempt under Rule 16b-7, each Common Share was reclassified (the "Reclassification") into 0.5 Class A voting shares of the Issuer, no par value ("Class A Voting Shares"), and 0.5 Class B non-voting shares of the Issuer, no par value ("Class B Non-Voting Shares").

F2 · kind: In connection with the Reclassification, pursuant to a notice dated February 10, 2017 given by the Bank as calculation agent, the terms of the Transaction were adjusted to reflect the Reclassification with no change to the economic rights and obligations of either Liberty or the Bank. As adjusted, the Transaction relates to units consisting of 0.5 shares of the Class A Voting Shares and 0.5 shares of the Class B Non-Voting Shares.

F3 · kind: As previously reported, Liberty received a cash payment of $70,889,585.00 as of the date of entering into the Transaction.

In most circumstances, Liberty retained voting rights in the Pledged Shares during the term of the pledge, but Liberty is obligated to share with the Bank the economic benefit of any dividends paid during the term of the pledge based on a formula that takes into account a theoretical hedging position by the Bank.

F4 · kind: The Transaction is divided into three individual tranches (each a "Tranche") with each Tranche divided into 25 individual components (each a "Component") designated by a valuation date; the Components for Tranche 1 are the 25 trading days from July 25, 2019 through August 28, 2019, inclusive; the Components for Tranche 2 are the 25 trading days from October 23, 2020 through November 30, 2020, inclusive; and the Components for Tranche 3 are the 25 trading days from January 25, 2022 through March 1, 2022, inclusive.

F5 · kind: On the settlement date for each Component, Liberty will deliver to the Bank a cash equivalent of the following (unless share settlement is elected): (a) if the sum of the volume weighted average trading price per Class A Voting Share multiplied by 0.5 and the volume weighted average trading price per Class B Non-Voting Share multiplied by 0.5 on the valuation date for the relevant Component ("Settlement Price") is less than $33.167 (the "Forward Floor Price"), 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares (or, in the case of the last Component in each Tranche, (A) in the case of each of Tranche 1 and 2, 16,658.5 Class A Voting Shares and 16,658.5 Class B Non-Voting Shares, and (B) in the case of Tranche 3, 16,659 Class A Voting Shares and 16,659 Class B Non-Voting Shares) ("Number of Shares");

F6 · kind: (b) if the Settlement Price is greater than the Forward Floor Price but less than or equal to $52.677 ("Forward Cap Price"), the Number of Shares multiplied by the Forward Floor Price divided by the Settlement Price; and (c) if the Settlement Price is greater than the Forward Cap Price, the Number of Shares multiplied by (1 - ((Forward Cap Price - Forward Floor Price), divided by the Settlement Price)).

F7 · kind: On 08/02/2019, the seventh component of Tranche 1 matured, which the Reporting Person cash settled. The Settlement Price was below the Forward Floor Price; therefore, the Reporting Person paid $404,884.76 in cash to the Bank and the Pledged Shares were reduced by 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares.

F1 · kind: As previously reported, on November 12, 2015, Liberty Global Incorporated Limited ("Liberty"), a wholly-owned subsidiary of Liberty Global plc, entered into a Variable Pre-paid Forward Transaction ("Transaction") with an unaffiliated bank ("Bank") relating to 2,500,000 common shares of the Issuer, no par value ("Common Shares"), and subsequently, pursuant to a reclassification exempt under Rule 16b-7, each Common Share was reclassified (the "Reclassification") into 0.5 Class A voting shares of the Issuer, no par value ("Class A Voting Shares"), and 0.5 Class B non-voting shares of the Issuer, no par value ("Class B Non-Voting Shares").

F2 · kind: In connection with the Reclassification, pursuant to a notice dated February 10, 2017 given by the Bank as calculation agent, the terms of the Transaction were adjusted to reflect the Reclassification with no change to the economic rights and obligations of either Liberty or the Bank. As adjusted, the Transaction relates to units consisting of 0.5 shares of the Class A Voting Shares and 0.5 shares of the Class B Non-Voting Shares.

F3 · kind: As previously reported, Liberty received a cash payment of $70,889,585.00 as of the date of entering into the Transaction. Liberty pledged 2,500,000 Common Shares to the Bank to secure its obligations under the Transaction; in connection with the Reclassification, such pledged Common Shares were replaced by a pledge by Liberty of 1,250,000 Class A Voting Shares and 1,250,000 Class B Non-Voting Shares (collectively, the "Pledged Shares"). In most circumstances, Liberty retained voting rights in the Pledged Shares during the term of the pledge, but Liberty is obligated to share with the Bank the economic benefit of any dividends paid during the term of the pledge based on a formula that takes into account a theoretical hedging position by the Bank.

F4 · kind: The Transaction is divided into three individual tranches (each a "Tranche") with each Tranche divided into 25 individual components (each a "Component") designated by a valuation date; the Components for Tranche 1 are the 25 trading days from July 25, 2019 through August 28, 2019, inclusive; the Components for Tranche 2 are the 25 trading days from October 23, 2020 through November 30, 2020, inclusive; and the Components for Tranche 3 are the 25 trading days from January 25, 2022 through March 1, 2022, inclusive.

F5 · kind: On the settlement date for each Component, Liberty will deliver to the Bank a cash equivalent of the following (unless share settlement is elected): (a) if the sum of the volume weighted average trading price per Class A Voting Share multiplied by 0.5 and the volume weighted average trading price per Class B Non-Voting Share multiplied by 0.5 on the valuation date for the relevant Component ("Settlement Price") is less than $33.167 (the "Forward Floor Price"), 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares (or, in the case of the last Component in each Tranche, (A) in the case of each of Tranche 1 and 2, 16,658.5 Class A Voting Shares and 16,658.5 Class B Non-Voting Shares, and (B) in the case of Tranche 3, 16,659 Class A Voting Shares and 16,659 Class B Non-Voting Shares) ("Number of Shares");

F6 · kind: (b) if the Settlement Price is greater than the Forward Floor Price but less than or equal to $52.677 ("Forward Cap Price"), the Number of Shares multiplied by the Forward Floor Price divided by the Settlement Price; and (c) if the Settlement Price is greater than the Forward Cap Price, the Number of Shares multiplied by (1 - ((Forward Cap Price - Forward Floor Price), divided by the Settlement Price)).

F9 · kind: On 08/01/2019, the sixth component of Tranche 1 matured, which the Reporting Person cash settled. The Settlement Price was below the Forward Floor Price; therefore, the Reporting Person paid $416,036.65 in cash to the Bank and the Pledged Shares were reduced by 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares.

F1 · price: As previously reported, on November 12, 2015, Liberty Global Incorporated Limited ("Liberty"), a wholly-owned subsidiary of Liberty Global plc, entered into a Variable Pre-paid Forward Transaction ("Transaction") with an unaffiliated bank ("Bank") relating to 2,500,000 common shares of the Issuer, no par value ("Common Shares"), and subsequently, pursuant to a reclassification exempt under Rule 16b-7, each Common Share was reclassified (the "Reclassification") into 0.5 Class A voting shares of the Issuer, no par value ("Class A Voting Shares"), and 0.5 Class B non-voting shares of the Issuer, no par value ("Class B Non-Voting Shares").

F4 · price: The Transaction is divided into three individual tranches (each a "Tranche") with each Tranche divided into 25 individual components (each a "Component") designated by a valuation date; the Components for Tranche 1 are the 25 trading days from July 25, 2019 through August 28, 2019, inclusive; the Components for Tranche 2 are the 25 trading days from October 23, 2020 through November 30, 2020, inclusive; and the Components for Tranche 3 are the 25 trading days from January 25, 2022 through March 1, 2022, inclusive.

F1 · price: As previously reported, on November 12, 2015, Liberty Global Incorporated Limited ("Liberty"), a wholly-owned subsidiary of Liberty Global plc, entered into a Variable Pre-paid Forward Transaction ("Transaction") with an unaffiliated bank ("Bank") relating to 2,500,000 common shares of the Issuer, no par value ("Common Shares"), and subsequently, pursuant to a reclassification exempt under Rule 16b-7, each Common Share was reclassified (the "Reclassification") into 0.5 Class A voting shares of the Issuer, no par value ("Class A Voting Shares"), and 0.5 Class B non-voting shares of the Issuer, no par value ("Class B Non-Voting Shares").

F4 · derivative.expiration_date: The Transaction is divided into three individual tranches (each a "Tranche") with each Tranche divided into 25 individual components (each a "Component") designated by a valuation date; the Components for Tranche 1 are the 25 trading days from July 25, 2019 through August 28, 2019, inclusive; the Components for Tranche 2 are the 25 trading days from October 23, 2020 through November 30, 2020, inclusive; and the Components for Tranche 3 are the 25 trading days from January 25, 2022 through March 1, 2022, inclusive.

F5 · derivative.expiration_date: On the settlement date for each Component, Liberty will deliver to the Bank a cash equivalent of the following (unless share settlement is elected): (a) if the sum of the volume weighted average trading price per Class A Voting Share multiplied by 0.5 and the volume weighted average trading price per Class B Non-Voting Share multiplied by 0.5 on the valuation date for the relevant Component ("Settlement Price") is less than $33.167 (the "Forward Floor Price"), 16,667 Class A Voting Shares and 16,667 Class B Non-Voting Shares (or, in the case of the last Component in each Tranche, (A) in the case of each of Tranche 1 and 2, 16,658.5 Class A Voting Shares and 16,658.5 Class B Non-Voting Shares, and (B) in the case of Tranche 3, 16,659 Class A Voting Shares and 16,659 Class B Non-Voting Shares) ("Number of Shares");

F6 · derivative.expiration_date: (b) if the Settlement Price is greater than the Forward Floor Price but less than or equal to $52.677 ("Forward Cap Price"), the Number of Shares multiplied by the Forward Floor Price divided by the Settlement Price; and (c) if the Settlement Price is greater than the Forward Cap Price, the Number of Shares multiplied by (1 - ((Forward Cap Price - Forward Floor Price), divided by the Settlement Price)).

F8 · derivative.expiration_date: On 07/26/2019, the second component of Tranche 1 matured, which the Reporting Person cash settled.
