Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets and Liabilities	GOODWILL Our business consists of three operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups and (3) Other, which consists of management services on rigs owned by third-parties. Our two reportable segments, Floaters and Jackups, represent our reporting units. We have historically tested goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists. All of our goodwill was impaired as of December 31, 2015. At the beginning of 2015, our goodwill balance was $276.1 million, net of accumulated impairment of $3.0 billion. During 2015, we recorded non-cash losses on impairment of $192.6 million and $83.5 million for the Jackups and Floaters reporting units, respectively, which were included in loss on impairment in our consolidated statement of operations. As part of our annual 2015 goodwill impairment test, we considered the decline in oil prices, which resulted in significant capital spending reductions by our customers and corresponding deterioration in our forecasted day rates and utilization. Additionally, our stock price declined significantly from $35 at the end of 2014 to below $15 at the end of 2015. We concluded it was more-likely-than-not that the fair values of our reporting units were less than their carrying amounts. We utilized an income approach that was based on a discounted cash flow model, which included present values of cash flows to estimate the fair value of our reporting units and was based on unobservable inputs that require significant judgments for which there was limited information. The future cash flows were projected based on our estimates of future day rates, utilization, operating costs, capital requirements, growth rates and terminal values. Forecasted day rates and utilization took into account market conditions and our anticipated business outlook. We compared the estimated fair value of each reporting unit to the fair values of all assets and liabilities within the respective reporting unit to calculate the implied fair value of goodwill and recorded an impairment to goodwill for the difference.
