In 2018, 2017, and 2016, we capitalized $48 million, $29 million, and $30 million, respectively, for product and process technology with weighted-average useful lives of 10 years, 11 years, and 10 years, respectively. Expected amortization expense is $55 million for 2019, $38 million for 2020, $33 million for 2021, $23 million for 2022, and $17 million for 2023. In 2016, we acquired Tidal Systems, Ltd., a developer of PCIe NAND Flash storage controllers, to enhance our NAND Flash controller technology for $148 million. In connection therewith, we recognized $108 million of in-process R&D; $81 million of goodwill, which was derived from expected cost reductions and other synergies and was assigned to SBU; and $41 million of deferred tax liabilities; which, in aggregate, represented substantially all of the purchase price. The in-process R&D was valued using a replacement cost approach, which included inputs of reproduction cost, including developer's profit, and opportunity cost. We expect to begin amortizing the in-process R&D in 2019 and will amortize it over its estimated useful life. The goodwill is not deductible for tax purposes.
