Goodwill and Amortizable Intangible Assets

The Company has goodwill as well as certain amortizable intangible assets consisting of data acquisition costs, a member list, content, core technology and other intangible assets related to the purchase of a website domain name. The goodwill and amortizable intangible asset balances reflect the goodwill, member list, content and core technology acquired during the August 2, 2013 acquisition of substantially all the assets of BrightNest for a purchase price of $2,650, inclusive of $1,920 in acquired intangible assets and goodwill of $730. The purchase price consisted of $2,150 in cash paid at closing and an additional $500 that was paid during 2014 as contingent consideration on the one-year anniversary of the closing of the acquisition. Revenues and expenses related to BrightNest, which are not material, are included in the consolidated results of operations from the date of acquisition.

Amortization on the intangible assets is computed using the straight-line method over the estimated lives of the assets, which are six years and three years, respectively, for the member list and other intangible assets, including content, core technology and data acquisition costs. Amortizable intangible assets as of December 31, 2014 and 2013 are as follows:
