On January 12, 2015, we acquired 100% of the equity of TONBELLER Aktiengesellschaft for $59.6 million in cash. We recorded $14.9 million of intangible assets, which are being amortized using the straight-line method over a weighted average useful life of approximately 4.9 years. We allocated $46.4 million of goodwill to our Applications segment that was not deductible for tax purposes.
