Explanation of Responses:

( 1 )The reported transactions involve an extension of the seven-year exercise period on existing share options for an additional three-year period. For Form 4 reporting purposes, this is shown as if the outstanding option were to be cancelled and replaced by a new option. However, from the Issuer's perspective, no new option is issued, the Issuer has only extended the expiration term on the original grant, with the same pricing and other terms continuing to apply. ( 2 )Vesting and exercise of the existing option has not changed as a result of the extension and therefore the option continues to be immediately exercisable.

Remarks: 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.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
