Additions to goodwill represent goodwill from acquisitions made during the period. Adjustments to goodwill include translation adjustments resulting from fluctuations in the value of goodwill held in currencies other than U.S. dollars, as well as adjustments made for the finalization of the purchase price allocations.
Acquisition of Eisenberg Bros Ltd.
On January 9, 2015 we acquired certain assets and liabilities of Eisenberg Bros Ltd. ("EB"), which previously operated as our exclusive agent in Israel of FEI products and services.
The total purchase price of the acquisition was $5.4 million. We paid $0.2 million in transaction costs which were expensed as incurred and are recorded in selling, general and administrative costs in our consolidated statements of operations. The total purchase price was allocated to the net tangible and intangible assets acquired based on their preliminary fair values as of January 9, 2015. The fair value of net tangible liabilities assumed was $0.1 million and the fair value of net intangible assets acquired was $1.4 million, which consisted solely of customer relationships. The acquired customer relationships will be amortized over a period of 5 years. The excess of the purchase price over the fair value of the net assets acquired was $4.1 million, which was recorded as goodwill in the Industry Group. The goodwill arising from the acquisition is primarily related to expected future cash flows from synergies arising from the establishment of a sales and service workforce in Israel.
No pro forma financial information has been provided for this acquisition as it is not material.
Acquisition of Lithicon AS
On February 5, 2014 we acquired 100% of the outstanding shares of Lithicon AS (“Lithicon”), which has operations in Norway and Australia. Lithicon provides digital rock technology services and pore-scale micro computed tomography (“microCT”) equipment to oil and gas companies. In conjunction with the acquisition we have obtained the helical scan microCT product and associated software from the Australian National University through a licensing and development agreement.
The total purchase price of the acquisition was $68.0 million, plus an adjustment for the change in final closing accounts of $0.4 million. We paid $0.4 million in transaction costs. Those costs were expensed as incurred and are recorded in selling, general and administrative costs in our consolidated statements of operations. The total purchase price was allocated to the net tangible and intangible assets acquired based on their preliminary fair values as of February 5, 2014. The fair value of net tangible liabilities assumed was $7.7 million and the fair value of net intangible assets acquired was $22.0 million, which consisted of $18.6 million in developed technology, $2.2 million of customer relationships and $1.2 million of purchased backlog. Including an increase to net deferred tax liabilities of $8.1 million, the excess of the purchase price over the fair value of the net assets acquired was $46.9 million, which was recorded as goodwill in the Industry Group.
The goodwill arising from the acquisition of Lithicon is primarily related to expected future cash flows from expansion of our product offerings in the oil and gas market to include digital rock services, as well as synergies from the introduction of the microCT product to the existing FEI product suite.
The acquired developed technology, customer relationships and purchased backlog will be amortized over a period of 10 years, 5 years and 2 years, respectively.
Other Intangible Assets
Patents, trademarks and other acquired intangible assets are amortized using the straight-line method over their estimated useful lives of 2 to 10 years. Customer relationships are amortized using the straight-line method over their estimated useful lives of 5 to 10 years.
