the income approach indicates value for an asset or liability based on the present value of cash flow projected to be generated over the remaining economic life of the asset or liability being measured .both the amount and the duration of the cash flows are considered from a market participant perspective .our estimates of market participant net cash flows considered historical and projected pricing , remaining developmental effort , operational performance including company- specific synergies , aftermarket retention , product life cycles , material and labor pricing , and other relevant customer , contractual and market factors .where appropriate , the net cash flows are adjusted to reflect the uncertainties associated with the underlying assumptions , as well as the risk profile of the net cash flows utilized in the valuation .the adjusted future cash flows are then discounted to present value using an appropriate discount rate .projected cash flow is discounted at a required rate of return that reflects the relative risk of achieving the cash flows and the time value of money .the market approach is a valuation technique that uses prices and other relevant information generated by market transactions involving identical or comparable assets , liabilities , or a group of assets and liabilities .valuation techniques consistent with the market approach often use market multiples derived from a set of comparables .the cost approach , which estimates value by determining the current cost of replacing an asset with another of equivalent economic utility , was used , as appropriate , for property , plant and equipment .the cost to replace a given asset reflects the estimated reproduction or replacement cost , less an allowance for loss in value due to depreciation .the purchase price allocation resulted in the recognition of $ 2.8 billion of goodwill , all of which is expected to be amortizable for tax purposes .substantially all of the goodwill was assigned to our rms business .the goodwill recognized is attributable to expected revenue synergies generated by the integration of our products and technologies with those of sikorsky , costs synergies resulting from the consolidation or elimination of certain functions , and intangible assets that do not qualify for separate recognition , such as the assembled workforce of sikorsky .determining the fair value of assets acquired and liabilities assumed requires the exercise of significant judgments , including the amount and timing of expected future cash flows , long-term growth rates and discount rates .the cash flows employed in the dcf analyses are based on our best estimate of future sales , earnings and cash flows after considering factors such as general market conditions , customer budgets , existing firm orders , expected future orders , contracts with suppliers , labor agreements , changes in working capital , long term business plans and recent operating performance .use of different estimates and judgments could yield different results .impact to 2015 financial results sikorsky 2019s 2015 financial results have been included in our consolidated financial results only for the period from the november 6 , 2015 acquisition date through december 31 , 2015 .as a result , our consolidated financial results for the year ended december 31 , 2015 do not reflect a full year of sikorsky 2019s results .from the november 6 , 2015 acquisition date through december 31 , 2015 , sikorsky generated net sales of approximately $ 400 million and operating loss of approximately $ 45 million , inclusive of intangible amortization and adjustments required to account for the acquisition .we incurred approximately $ 38 million of non-recoverable transaction costs associated with the sikorsky acquisition in 2015 that were expensed as incurred .these costs are included in other income , net on our consolidated statements of earnings .we also incurred approximately $ 48 million in costs associated with issuing the $ 7.0 billion november 2015 notes used to repay all outstanding borrowings under the 364-day facility used to finance the acquisition .the financing costs were recorded as a reduction of debt and will be amortized to interest expense over the term of the related debt .supplemental pro forma financial information ( unaudited ) the following table presents summarized unaudited pro forma financial information as if sikorsky had been included in our financial results for the entire years in 2015 and 2014 ( in millions ) : .
[['', '2015', '2014'], ['net sales', '$ 45366', '$ 47369'], ['net earnings', '3534', '3475'], ['basic earnings per common share', '11.39', '10.97'], ['diluted earnings per common share', '11.23', '10.78']]
the unaudited supplemental pro forma financial data above has been calculated after applying our accounting policies and adjusting the historical results of sikorsky with pro forma adjustments , net of tax , that assume the acquisition occurred on january 1 , 2014 .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 .
