Goodwill, Impaired [Abstract]
Goodwill	Goodwill Goodwill was recorded in connection with various acquisitions but was written-off as of December 31, 2011. We evaluated the recoverability of goodwill by comparing the carrying value of our reporting units to their fair value. Fair value was determined using discounted cash flows supplemented by market-based assessments of fair value, and impairment was measured as the difference between the resulting implied fair value of goodwill and its recorded carrying value. The determination of fair value was significantly impacted by estimates related to current market valuations, current and future economic conditions in each of our geographical markets, and our strategic plans within each of our markets. In the third quarter of 2011, we performed an event-driven assessment of the recoverability of goodwill. This assessment was necessary primarily due to sustained declines in our market capitalization. In performing the goodwill impairment analysis, we used management's estimates of the future cash flows for each reporting unit, which were required to consider the decrease in our market capitalization. The results of this analysis determined that a goodwill impairment charge of $240.5 million in the third quarter of 2011 was required.
