During the first quarters of 2017 and 2016, we capitalized $8 million and $9 million, respectively, for product and process technology with weighted-average useful lives of nine years. Amortization expense was $27 million and $31 million for the first quarters of 2017 and 2016, respectively. The expected amortization expense is $82 million for the remainder of 2017, $94 million for 2018, $46 million for 2019, $30 million for 2020, and $26 million for 2021.
