Unaudited Condensed Consolidated Financial Statements Basis of Presentation The accompanying condensed consolidated financial statements of LivaNova as of, and for the three and six months ended June 30, 2018 and June 30, 2017, have been prepared in accordance with U.S. GAAP for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. The accompanying condensed consolidated balance sheet of LivaNova at December 31, 2017 has been derived from audited financial statements contained in our 2017 Form 10-K, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of only normal recurring adjustments) considered necessary for a fair statement of the operating results of LivaNova and its subsidiaries, for the three and six months ended June 30, 2018 and are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The financial information presented herein should be read in conjunction with the audited consolidated financial statements and notes thereto accompanying our 2017 Form 10-K. Sale of our Cardiac Rhythm Management Business Franchise We completed the sale of our Cardiac Rhythm Management (“CRM”) business franchise to MicroPort Cardiac Rhythm B.V. and MicroPort Scientific Corporation (the “CRM Sale”) on April 30, 2018 for total cash proceeds of $195.9 million, less cash transferred of $9.2 million, subject to certain closing adjustments. In conjunction with the CRM Sale, we entered into transition services agreements to provide certain support services for generally up to twelve months from the closing date of the sale. We previously concluded that the sale of CRM represents a strategic shift in our business that will have a major effect on future operations and financial results. As a result, we classified the operating results of CRM as discontinued operations in our condensed consolidated statements of income. The assets and liabilities of CRM are presented as assets or liabilities of discontinued operations in the condensed consolidated balance sheet at December 31, 2017. Reclassification of Prior-Year Comparative Period Presentation We have reclassified certain prior period amounts for comparative purposes. These reclassifications did not have a material effect on our financial condition, results of operations or cash flows. To conform the presentation on the condensed consolidated statement of cash flows for the six months ended June 30, 2017, to the presentation for the year ended December 31, 2017 in our 2017 Form 10-K, loans to cost and equity method investees of $6.8 million was reclassified to Investing Activities from Financing Activities. We reclassified $34.0 million to contingent consideration from other long-term liabilities at December 31, 2017 to conform to the presentation on the condensed consolidated balance sheet at June 30, 2018. Significant Accounting Policies Our significant accounting policies are detailed in "Note 2: Basis of Presentation, Use of Accounting Estimates and Significant Accounting Policies" of our 2017 Form 10-K. On January 1, 2018, we adopted ASC Update (“ASU”) No 2014-09, Revenue from Contracts with Customers. Refer to “Note 2. Revenue Recognition.” We elected the cumulative effect transition method; however, we recognized no cumulative effect to the opening balance of retained earnings because the impact on the timing of when revenue is recognized within our Cardiac Surgery segment, specifically related to heart-lung machines and preventative maintenance contracts on cardiopulmonary equipment, was insignificant. The timing of revenue recognition for products and related revenue streams within our Neuromodulation segment and discontinued operations did not change.
