NOTE B - ACQUISITIONS AND DISPOSITIONS Acquisition of Optima In March 2012, we acquired 100% of the outstanding common stock of Optima Solutions Holdings Limited (Optima), a provider of rig cooling services and associated products that suppress heat generated by high rate flaring of hydrocarbons during well test operations. The acquisition of Optima, which is based in Aberdeen, Scotland, enables our Production Testing segment to provide its customers with a broader range of production testing and associated services, and expands the segment's presence in many significant global markets. Including the impact of additional working capital received and other adjustments to the purchase price, we paid 41.2 million pounds sterling (approximately $65.0 million equivalent) in cash as the purchase price for the Optima stock at closing, and may pay up to an additional 4 million pounds sterling in contingent purchase price consideration, depending on a defined measure of earnings for Optima over each of the two years subsequent to the closing. We allocated the purchase price to the fair value of the assets and liabilities acquired, which consisted of approximately: $3.0 million of net working capital; $16.8 million of property, plant, and equipment; $20.4 million of certain intangible assets; $6.1 million of deferred tax liabilities and $3.5 million of other liabilities associated with the contingent purchase price consideration obligation; and $34.5 million of nondeductible goodwill. This allocation of the purchase price to Optima's net assets and liabilities is preliminary and subject to the potential identification of additional assets and contingencies or revisions to the fair value calculations. These fair value calculations and allocations are expected to be finalized later during 2012 and could result in adjustments to the calculated depreciation and amortization of the tangible and intangible assets, respectively that were acquired.
