pre_text: notes to the consolidated financial statements non-financial assets and liabilities measured at fair value on a non-recurring basis during 2009 , we classified the atlantic star as held for sale and recognized a charge of $ 7.1 million to reduce the carrying value of the ship to its fair value less cost to sell based on a firm offer received during 2009 . this amount was recorded within other operating expenses in our consolidated statement of operations . we determined the fair market value of the atlantic star as of december 31 , 2010 based on comparable ship sales adjusted for the condition , age and size of the ship . we have categorized these inputs as level 3 because they are largely based on our own assump- tions . as of december 31 , 2010 , the carrying amount of the atlantic star which we still believe represents its fair value was $ 46.4 million . the following table presents a reconciliation of the company 2019s fuel call options 2019 beginning and ending balances as follows ( in thousands ) : fair value fair value measurements measurements using significant using significant unobservable unobservable year ended december 31 , 2010 inputs ( level 3 ) year ended december 31 , 2009 inputs ( level 3 ) fuel call options fuel call options balance at january 1 , 2010 $ 9998 balance at january 1 , 2009 $ 2007 2007 2007 2007 2014 total gains or losses ( realized/ unrealized ) total gains or losses ( realized/ unrealized ) .
