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. See Note 5 for additional information.

Restructuring charges/other

Restructuring charges/other are included in Other for segment reporting purposes.

As of March 31, 2018, we have recognized $21 million of restructuring charges for severance and benefit costs related to the previously reported reorganization of the product lines within our two reportable segments. We have paid $18 million to terminated employees for severance and benefits. Any further charges are not expected to be material.

As of March 31, 2018, we have recognized $33 million of restructuring charges for severance and benefits costs, as well as accelerated depreciation, related to the phase out of a manufacturing facility in Greenock, Scotland. Total restructuring charges, primarily severance and benefit costs, are estimated to be about $40 million. The remaining charges are expected to be recognized through 2019.

Changes in accrued restructuring balances are as follows:

Balance, December 31, 2017	$	29
Restructuring charges		1
Non-cash items (a)		1
Payments		(2	)
Balance, March 31, 2018	$	29

(a)	Reflects charges for impacts of accelerated depreciation and changes in exchange rates.

The restructuring accrual balances are primarily reported as a component of either Accrued expenses and other liabilities or Other long-term liabilities on our Consolidated Balance Sheets, depending on the expected timing of payment.
