Amortizable intangible assets are amortized on a straight-line basis over their useful lives.

Aggregate amortization expense incurred by the Company for the years ended December 31, 2009, 2010 and 2011, was approximately $5.5 million, $2.7 million and $5.5 million, respectively. Based upon the current amount of acquired intangible assets subject to amortization, the estimated amortization expense for the next five years is as follows: $4.7 million in 2012, $2.9 million in 2013, $433,000 in 2014, and $0 thereafter.
