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 30, 2016, we and Baker Hughes mutually terminated our merger agreement primarily because of the challenges in obtaining remaining regulatory approvals and general industry conditions that severely damaged deal economics.

In April 2015, we had 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. Since our proposed divestitures no longer met the assets held for sale accounting criteria at March 31, 2016, we reclassified these businesses to assets held and used in the accompanying condensed consolidated balance sheets for both periods presented. We recorded corresponding charges during the first quarter of 2016 totaling $464 million within "Baker Hughes related costs and termination fee" in our condensed consolidated statements of operations, which included $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.
