Recently Issued Accounting Standards 2  Business Combinations The fair value of the customer relationships acquired was calculated using a discounted cash flow method (excess earnings)  and is being amortized using a declining balance method derived from projected customer revenue over an average estimated  useful life of 13 years. The fair value of the developed technology acquired was calculated using a discounted cash flow method  (relief from royalty) and is being amortized using the straight-line method over an estimated useful life of five years. The allocation of the purchase price to the estimated fair value of the assets acquired and liabilities assumed at the acquisition date is as follows: Upon acquisition, we received a cash payment of $7.5 million from NSN and recorded a bargain purchase gain of $1.8 million, net of income taxes, subject to customary working capital adjustments between the parties as defined in the purchase agreement. As of December 31, 2013, the parties were in the process of negotiating final working capital adjustments. We have adjusted the purchase price allocation to record additional estimated liabilities and an estimated receivable from NSN related to working capital adjustments under negotiation. The bargain purchase gain of $1.8 million  represents the excess of the consideration exchanged over the fair value of the assets acquired and liabilities assumed. We have assessed the recognition and measurements of the assets acquired and liabilities assumed based on historical and pro forma data for future periods and have concluded that our valuation procedures and resulting measures were appropriate. The gain is included in the line item “Gain on bargain purchase of a business” in the 2012 Consolidated Statements of Income. On May 4, 2012, we acquired the NSN BBA business. This acquisition provides us with an established customer base in key  markets and complementary, market-focused products and was accounted for as a business combination. We have included  the financial results of the NSN BBA business in our consolidated financial statements since the date of acquisition. These  revenues are included in the Carrier Networks division in the Broadband Access subcategory. In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Reporting of Amounts Reclassified Out  of Accumulated Other Comprehensive Income (ASU 2013-02). ASU 2013-02 requires entities to provide information about  the amounts reclassified out of accumulated other comprehensive income by component either on the face of the financial  statements or in the footnotes. ASU 2013-02 does not change the current requirements for reporting net income or other  comprehensive income in the financial statements. This update is effective prospectively for reporting periods beginning  after December 15, 2012. We adopted this amendment during the first quarter of 2013, and we have provided the disclosures  required for the years ended December 31, 2013, 2012 and 2011 in Note 1 of Notes to Consolidated Financial Statements. During 2013, we adopted the following accounting standards, which had no material effect on our consolidated results of  operations or financial condition: (In thousands) Other receivables $9,486 Inventory 21,068 Property, plant and equipment  5,035 Accounts payable (5,194) Unearned revenue (18,203) Accrued expenses (3,361) Accrued wages and benefits (2,251) Deferred tax liability (788) Non-current unearned revenue (19,886) Net liabilities assumed (14,094) Customer relationships 5,162 Developed technology 3,176 Other 13 Gain on bargain purchase of a business, net of tax (1,753) Net consideration received by seller $(7,496) Financial Results 47
