Goodwill

As of September 30, 2012 and December 31, 2011, goodwill totaled $5.3 million. There was no goodwill activity for the nine and three months ended September 30, 2012 and 2011. Goodwill is tested for impairment annually as of November 30, or when events or circumstances suggest that an impairment may exist. For periods in which the recorded value is greater than the estimated fair value, the resulting write-down is charged to results of operations. For tax purposes, the goodwill is included in the Company's basis in its investments in StreetLinks and Mango as they are limited liability companies. Therefore, it will be non-deductible for tax purposes as long as the Company holds its investments.
