Acquisition of Business [Abstract] |
Acquisition of Business | Acquisition of Business On May 12, 2016 we acquired all of the outstanding capital stock of Cruise, an autonomous vehicle technology company, to further accelerate our development of autonomous vehicles. The deal consideration at closing was $581 million, of which $291 million was paid in cash and approximately $290 million was paid through the issuance of new common stock. The fair value of the common stock issued was determined based on the closing price of our common stock on May 12, 2016. In conjunction with the acquisition, we entered into other agreements that will result in future costs contingent upon the continued employment of key individuals and additional performance-based awards contingent upon the achievement of specific technology and commercialization milestones. Of the total consideration, $130 million was allocated to intangible assets, primarily in-process research and development with an indefinite life until fully developed and commercialized, $39 million was allocated to deferred tax liabilities, net of other assets, and $490 million was allocated to non-tax-deductible goodwill in Corporate primarily related to the synergies expected to arise as a result of the acquisition.
