(CTG) for $51.7 million in cash, net of cash acquired. Based on the Company's preliminary purchase price allocation, $28.6 million was identifiable intangible assets and $28.4 million was goodwill. The fair value of the intangible assets was based upon an independent valuation and will be amortized over a weighted-average useful life of 15 years. The ultimate purchase price allocation will be based on information that provides a better estimate of the fair value of assets acquired and liabilities assumed. 7 11 false HundredThousands UnKnown UnKnown true true
