In the first quarters of 2019 and 2018, we capitalized $49 million and $9 million, respectively, for product and process technology with weighted-average useful lives of 7 years and 10 years, respectively, and placed in service $108 million of in-process R&D in the first quarter of 2019, which is being amortized on a straight-line basis over 6 years. Expected amortization expense is $55 million for the remainder of 2019, $64 million for 2020, $58 million for 2021, $47 million for 2022, and $40 million for 2023.
