During 2010, certain Maritech oil and gas property impairments of $63.8 million were charged to earnings. The majority of the oil and gas property impairments for 2010 were due to increased estimates of Maritech's decommissioning liabilities. For a portion of these impaired properties, however, the change in the fair value of the properties was due to decreased expected future cash flows based on forward oil and natural gas pricing data from published sources. Because such published forward pricing data was applied to estimated oil and gas reserve volumes based on our internally prepared reserve estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy. Also during 2010, our Offshore Services segment recorded impairments for certain equipment assets, including the Epic Diver. In addition, our Fluids segment recorded an impairment for its Lake Charles, Louisiana, calcium chloride plant. The fair values of these assets were based on their resale value based on purchase offers received or their estimated salvage values.

A summary of these nonrecurring fair value measurements as of December 31, 2010, using the fair value hierarchy is as follows:
