During the first six months of 2017 and 2016, we capitalized $14 million and $16 million, respectively, for product and process technology with weighted-average useful lives of ten years. Amortization expense was $27 million and $54 million for the second quarter and first six months of 2017, respectively, and $29 million and $60 million for the second quarter and first six months of 2016, respectively. Expected amortization expense is $55 million for the remainder of 2017, $95 million for 2018, $47 million for 2019, $31 million for 2020, and $27 million for 2021.
