(1) As a result of the BTG Acquisition, we recognized goodwill attributable to the synergies expected to arise from the BTG Acquisition and revenue and cash flow projections associated with future technologies. The goodwill is not deductible for tax purposes. As of September 30, 2019, given the preliminary nature of the BTG Acquisition purchase price allocation, we have not yet allocated goodwill to the relevant reporting units and/or reportable segments.
