(k) Accounting for Share-Based Payments and Long-Term Incentive Plans

The Company operates an employee long-term incentive plan, comprised of Performance Units and Exit Units, the terms and conditions of which are described in Note 17. The Company applies a fair-value based measurement method in calculating the compensation costs of Performance Units which are recognized on a straight-line basis over the vesting period.

Certain employees of the Company participate in a Management Equity Plan (“MEP”), comprising stock options to acquire non-voting shares in a related party affiliate of the Company, at no cost to the employee. The terms and conditions of the MEP are described in Note 17. The Company recognizes compensation costs for these awards with performance conditions if, and when, the Company concludes that it is probable that the performance condition(s) will be achieved, over the requisite service period. The Company reviews and evaluates these estimates regularly and will recognize any remaining unrecognized compensation expense as an estimate revision. The stock options vest upon a number of performance conditions; an exit or liquidity event occurring; a two-year cumulative operating income hurdle being achieved over the vesting period; and certain other contractual terms being achieved. The Company applies fair-value based measurement principles to determine grant date values for the stock options. The Company has made an entity-wide accounting election to account for award forfeitures as they occur.

### Accounting for Business Combinations
The Company accounts for a transaction as a business combination where the assets acquired and liabilities assumed following a transaction constitute a business. An acquired entity must have inputs and processes that make it capable of generating a return or economic benefit to be considered a business. If the assets acquired are not a business, the Company accounts the transaction as an asset acquisition. The Company recognizes and measures at fair value 100 percent of the assets and liabilities of any acquired business. Goodwill is recognized and measured as the difference between the consideration paid or payable less the fair value of assets acquired.

The Company accounts for the disposal of subsidiary undertakings when it ceases to control the subsidiary’s assets and liabilities or the group of assets. A gain or loss is recognized and measured as the difference between the fair value of consideration received
