The Company recorded amortization expense related to its intangible assets, excluding the fair market value of leases, of $17.5 million, $8.2 million and $6.6 million for the years ended December 31, 2012, 2011 and 2010, respectively. The estimated future amortization expense associated with the Company’s intangible assets, excluding the fair market value of leases, is $24.8 million, $19.5 million, $15.3 million, $12.6 million and $9.6 million for the years ending December 31, 2013, 2014, 2015, 2016 and 2017, respectively.

During 2012, the Company identified an error in the consolidated financial statements related to prior years. The error was attributable to a purchase price allocation of an asset acquired in 2004 and related amortization of the intangible asset. The Company concluded that the adjustment was not material to the results for the year ended December 31, 2012, or any prior periods. Consequently, the Company recorded an out-of-period adjustment to increase Net Loss attributable to DDR by $1.5 million in 2012. The Company also decreased land and increased other assets by $4.4 million on the consolidated balance sheet.
