In April 2015, we announced our decision to market for sale our Fixed Cutter and Roller Cone Drill Bits, our Directional Drilling, and our Logging-While-Drilling/Measurement-While-Drilling businesses in connection with the anticipated Baker Hughes transaction. Accordingly, beginning in April 2015, the assets and liabilities for these businesses, which are included within our Drilling and Evaluation operating segment, were classified as held for sale and the corresponding depreciation and amortization expense ceased at that time. Based on the events discussed above, we have determined that our proposed divestitures no longer meet the assets held for sale accounting criteria at March 31, 2016, and have reclassified these businesses to assets held and used in the accompanying condensed consolidated balance sheets for both periods presented. We recorded corresponding charges totaling $464 million within "Baker Hughes acquisition-related costs" on our condensed consolidated statements of operations for the three months ended March 31, 2016, which includes $329 million of accumulated unrecognized depreciation and amortization expense for these businesses during the period the associated assets were classified as held for sale, including the first quarter of 2016, along with $135 million of capitalized and other divestiture-related costs incurred during the first quarter. The reclassification of assets held for sale to assets held and used resulted in the following changes from amounts previously reported on our condensed consolidated balance sheets as of December 31, 2015: - $2.1 billion decrease in "Assets held for sale;" - $576 million increase in "Inventories;" - $1.2 billion increase in "Property, plant, and equipment;" - $276 million increase in "Goodwill;" - $57 million increase in "Other assets;" - $24 million increase in "Accrued employee compensation and benefits;" - $46 million decrease in "Other current liabilities;" and - $22 million increase in "Employee compensation and benefits." Beginning April 1, 2016, all depreciation and amortization expense associated with these businesses will be included in operating costs and expenses on our condensed consolidated statements of operations. According to the terms of the merger agreement, we were required to pay Baker Hughes a termination fee of $3.5 billion. This amount was paid on May 4, 2016. The expense for this payment, which is tax-deductible, will be recognized in our consolidated financial statements for the second quarter of 2016. As a result of the termination of the merger agreement, we are required to redeem $2.5 billion of the senior notes we issued in November 2015 at a price of 101% of their principal amount, plus accrued and unpaid interest. Accordingly, we reclassified $2.5 billion of our senior notes to "Current maturities of long-term debt" on our condensed consolidated balance sheets as of March 31, 2016, which includes $1.25 billion of 2.7% senior notes due 2020 and $1.25 billion of 3.375% senior notes due 2022. These notes will be redeemed in the second quarter of 2016. We terminated our senior unsecured bridge facility for the acquisition as of March 31, 2016.

Termination of Baker Hughes acquisition

In November 2014, we entered into a merger agreement with Baker Hughes to acquire all outstanding shares of Baker Hughes in a stock and cash transaction. On April 6, 2016, the U.S. Department of Justice (DOJ) filed a civil antitrust lawsuit seeking to block the proposed acquisition. Additionally, the European Commission entered into Phase II of its investigation in January 2016 and issued a Statement of Objections to us and Baker Hughes on April 29, 2016 outlining its concerns with the acquisition. On April 30, 2016, primarily because of the challenges in obtaining remaining regulatory approvals and general industry conditions that severely damaged deal economics, we and Baker Hughes mutually terminated our merger agreement.

In April 2015, we announced our decision to market for sale our Fixed Cutter and Roller Cone Drill Bits, our Directional Drilling, and our Logging-While-Drilling/Measurement-While-Drilling businesses in connection with the anticipated Baker Hughes transaction.
