The unaudited pro forma financial results include certain adjustments for additional depreciation and amortization expense based upon the fair value step-up and estimated useful lives of Solutia depreciable fixed assets and definite-life amortizable assets acquired in the transaction.B B The unaudited pro forma results also include adjustments to net interest expense and elimination of early debt extinguishment costs historically recorded by Solutia based upon the retirement of Solutia's debtB and issuance of additional debt related to the transaction.B B The provision for income taxes from continuing operations has also been adjusted for all periods, based upon the foregoing adjustments to historical results, as well as the elimination of historical net changes in valuation allowances against certain deferred tax assets of Solutia. Additionally, in the preparation of unaudited pro forma sales and earnings from continuing operations including noncontrolling interest, Solutia's historical consolidated results have been retrospectively adjusted for the change in accounting methodology for pension and other post-employment benefit ("OPEB") plans actuarial gains and losses adopted by Eastman during first quarter 2012.B B For additional information, see Note 14, "Accounting Methodology Change for Pension and Other Postretirement Benefit Plans" in Part II, Item 8 of the Company's 2012 Annual Report on Form 10-K. | | |
