Included in other noncurrent assets.

During the first quarters of 2016 and 2015, we capitalized $9 million and $12 million, respectively, for product and process technology with weighted-average useful lives of nine years and eight years, respectively. Amortization expense was $31 million and $30 million for the first quarters of 2016 and 2015, respectively.  The expected annual amortization expense for intangible assets held as of December 3, 2015 is $120 million for 2016, $104 million for 2017, $92 million for 2018, $44 million for 2019, and $28 million for 2020.

On October 2, 2015, 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 other expected cost reductions and synergies and was assigned to our Storage Business Unit; 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 will begin amortizing the in-process R&D when development is complete, which is estimated to be in 2017, and will amortize it over its then estimated useful life. The goodwill is not expected to be deductible for tax purposes.
