In accordance with ASC 350, the Company amortizes its intangible assets with finite lives over their respective estimated useful lives and reviews for impairment whenever impairment indicators exist. Impairment indicators could include significant under-performance relative to the historical or projected future operating results, significant changes in the manner of use of assets, significant negative industry or economic trends or significant changes in the Company’s market capitalization relative to net book value. Any changes in key assumptions used by the Company, including those set forth above, could result in an impairment charge and such a charge could have a material adverse effect on the Company’s consolidated results of operations. The Company’s intangible assets consist of customer lists, noncompete agreements, trade names and patents. The Company’s customer lists, which have an estimated weighted-average useful life of approximately fourteen years, are being amortized using the economic life method. The Company’s noncompete agreements, trade names and patents are being amortized on a straight-line basis over their estimated weighted-average useful lives of approximately four years, thirteen years and nine years, respectively.
