Goodwill And Intangible Assets
8. Goodwill and Intangible Assets
 
Goodwill represents the excess purchase price over the fair value of net assets acquired, or net liabilities assumed, in a business combination. In accordance with ASC Topic 350, Intangibles – Goodwill and Other, the Company performs an annual impairment test of goodwill. The Company evaluates goodwill as of October 1 each year and more frequently if events or changes in circumstances indicate that goodwill might be impaired.  

Other intangible assets include customer relationships, non-compete arrangements, customer backlog, trade names, and internally developed software, which are being amortized over the assets' estimated useful lives using the straight-line method. Estimated useful lives range from six months to ten years. Amortization of customer relationships, non-compete arrangements, customer backlog, trade names, and internally developed software is considered an operating expense and is included in "Amortization" in the accompanying Condensed Consolidated Statements of Operations. The Company periodically reviews the estimated useful lives of its identifiable intangible assets, taking into consideration any events or circumstances that might result in a lack of recoverability or revised useful life.
