tax , that assume the acquisition occurred on january 1 , 2015 . significant pro forma adjustments include the recognition of additional amortization expense related to acquired intangible assets and additional interest expense related to the short-term debt used to finance the acquisition . these adjustments assume the application of fair value adjustments to intangibles and the debt issuance occurred on january 1 , 2015 and are approximated as follows : amortization expense of $ 125million and interest expense of $ 40million . in addition , significant nonrecurring adjustments include the elimination of a $ 72million pension curtailment loss , net of tax , recognized in 2015 and the elimination of a $ 58 million income tax charge related to historic earnings of foreign subsidiaries recognized by sikorsky in 2015 . the unaudited supplemental pro forma financial information also reflects an increase in interest expense , net of tax , of approximately $ 110 million in 2015 . the increase in interest expense is the result of assuming the november 2015 notes were issued on january 1 , 2015 . proceeds of the november 2015 notes were used to repay all outstanding borrowings under the 364- day facility used to finance a portion of the purchase price of sikorsky , as contemplated at the date of acquisition . the unaudited supplemental pro forma financial information does not reflect the realization of any expected ongoing cost or revenue synergies relating to the integration of the two companies . further , the pro forma data should not be considered indicative of the results that would have occurred if the acquisition , related financing and associated notes issuance and repayment of the 364-day facility had been consummated on january 1 , 2015 , nor are they
