The date of the completion of the transfer from the Swiss Plan to the New Swiss Plan of the Swiss Transferred Assets is the “Swiss Transfer Date”. For the avoidance of doubt, any adjustment payment made subsequent to such transfer will not be taken into account for the purposes of this definition.

(B)

the value of the assets of the Swiss Plan in respect of the Remaining Members as of the Swiss Transfer Date (the “Swiss CH Asset Value”); less

(C)

the net pension Liability attributable to the Swiss CH Entities in the opening positions for Purchaser’s financial statements as of July 31, 2019, which shall be consistent with the methodology and assumptions used for calculating the Purchaser Pension Liabilities in the GlaxoSmithKline Consumer Healthcare Holdings Limited Annual Report 2018, with financial assumptions updated for market conditions.

(iii)

Seller Parent shall, within 45 days following receipt of the calculation of the Swiss Pension Adjustment and such information as it reasonably requires to verify it, in writing either confirm its agreement to such calculation (including the value of the Swiss CH Liability Value and the Swiss CH Asset Value) or notify Purchaser Parent in writing that it disagrees with the calculation, explaining why and providing its alternative calculation with any supporting documentation (including any alternative valuation of the Swiss CH Liability Value and the Swiss CH Asset Value). Where Seller Parent disagrees with Purchaser Parent’s calculations the provisions of Section 6.6(e)(vi) shall apply mutatis mutandis.

(iv)

Within 30 days following either confirmation by Seller Parent of its agreement of the Swiss Pension Adjustment or the determination of the Swiss Pension Adjustment in accordance with Section 6.6(e)(vi):

(v)

For purposes of this Agreement, (A) the Swiss Transferring Liability shall be Purchaser Parent Retained Liabilities; and (B) any Liabilities of or related to the Swiss Plan that do not transfer to the New Swiss Plan pursuant to this Section 6.6(t) shall be Purchaser Assumed Employee Liabilities. From and following the Swiss Transfer Date, Purchaser Parent and its Subsidiaries shall have no Liabilities in respect of the Swiss Plan.

(vi)

Purchaser shall pay to Purchaser Parent the amount of any Tax Benefit actually realized by Purchaser or its Subsidiaries in the taxable year in which the payment pursuant to Section 6.6(t)(iv)(A) is made or the subsequent two taxable years arising from any Tax Item in respect of any amount paid into the Swiss Plan up to an amount equal to that resulting from the true up under Section 6.6(t)(iv)(A) in respect of the Swiss Transferring Liability within fifteen (15) days of the filing of the Tax Return with respect to which the Tax Benefit is actually realized (or, if the Tax Benefit is in the form of an increased cash Tax refund, within fifteen (15) days of the receipt of such cash Tax refund from the applicable Governmental Authority).”
