[1] The contingent consideration represented the Company's best estimate, based on its review, at the time of purchase, of the underlying potential obligations estimated at a range of $8 million to $9 million, of certain Seller tax-related liabilities for which the Company has indemnified the Sellers as part of the purchase agreement. During 2012, the Company paid $4.9 million of additional purchase price related to the contingent consideration. No additional amounts were paid during 2013. The remaining liability range of $3.1 million to $4.1 million continues to represent the Company's best estimate of the remaining potential obligation at December 31, 2013.

[2] Deferred/contingent consideration includes approximately $9.8 million of both short-term and long-term deferred purchase price, based on set amounts and fixed payment schedules per the purchase agreement, and an additional $2.6 million of contingent consideration to be paid based on a multiple of future earnings, as defined.

[3] Consists of $33.0 million of customer relationships with an estimated 10 year useful life, $7.9 million of trademarks/trade names with an indefinite useful life and $7.5 million of technology and other intangible assets with an estimated eight year useful life.

[4] Consists of approximately $27.6 million of customer relationships with an estimated weighted average useful life of 10 years, $1.5 million of technology and other intangible assets with an estimated weighted average useful life of four years and $12.1 million of trademark/trade names with an indefinite useful life.
