In the case of annual incentive compensation, shares have been or will be issued to senior management and key employees pursuant to a shareholding incentive program. The shareholding incentive program allows these employees to elect to receive up to 100% of their annual incentive compensation in ordinary shares of Liberty Global in lieu of cash.

_______________

(a)Amounts represent the gross number of shares associated with option, SAR and PSAR awards issued to our current and former employees and our directors. Our company settles SARs and PSARs on a net basis when exercised by the award holder, whereby the number of shares issued represents the excess value of the award based on the market price of the respective Liberty Global shares at the time of exercise relative to the award’s exercise price. In addition, the number of shares issued is further reduced by the amount of the employee’s required income tax withholding.

(b)Amounts represent certain share-based awards that continue to be held by former employees of Liberty Global subsequent to certain split-off or disposal transactions. Although future exercises of these awards by former employees will not result in the recognition of share-based compensation expense, such exercises will increase the number of our outstanding ordinary shares.

The following table provides the aggregate number of restricted share units (RSUs) that were outstanding as of March 31, 2023. The number of shares to be issued on the vesting date of these awards will be reduced by the amount of the employee’s required income tax withholding.


	Class A	Class C


Held by Liberty Global employees	3,171,336	6,898,733


Held by former Liberty Global employees (a)	34,359	68,701
