Acquisition charges

Acquisition charges represent the ongoing amortization of intangible assets resulting from the acquisition of National Semiconductor Corporation. These amounts are included in Other for segment reporting purposes, consistent with how management measures the performance of its segments.

Amortization of acquisition-related intangibles was $79 million and $80 million for the first quarters of 2019 and 2018, respectively. Fully amortized assets are written off against accumulated amortization.
