Goodwill

Goodwill represents the excess of the purchase price of acquired businesses over the estimated fair value of the tangible and identifiable intangible net assets acquired. The evaluation of goodwill is performed in accordance with FASB ASC Topic 350, which requires an annual assessment of potential goodwill impairment at the reporting unit level. A reporting unit can be an operating segment or a business if discrete financial information is prepared and reviewed by management. The Company has three reporting units: Research, Consulting, and Events.

The following table presents changes to the carrying amount of goodwill by reporting unit during the six months ended June 30, 2013 (in thousands):
