As we have one operating segment, we allocate goodwill to one reporting unit for goodwill impairment testing. Goodwill is tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach based on the market capitalization of the reporting unit. Our annual impairment test was performed as of February 26, 2010. No impairment of goodwill has been identified during the period presented. Goodwill is deductible for tax purposes in certain jurisdictions.</font></div>Note 8 – GoodwillThe carrying amount of goodwill for 2009 and 2010 are as follows:   Amount(in thousands) Balance as of December 31,falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringThe carrying amount of goodwill, goodwill acquired during the year, goodwill impairment losses recognized, goodwill written off due to the sale of a business unit, goodwill not yet allocated, and any other changes to goodwill during the period in total and for each reportable segment.
