Restructuring and Other Initiatives

We have executed various restructuring and other initiatives and we plan to execute additional initiatives in the future, if necessary, to streamline manufacturing capacity and other costs to improve the utilization of remaining facilities. To the extent these programs involve voluntary separations, no liabilities are generally recorded until offers to employees are accepted. If employees are involuntarily terminated, a liability is generally recorded at the communication date. Related charges are recorded in Automotive cost of sales and Automotive selling, general and administrative expense. The following table summarizes the reserves and charges related to restructuring and other initiatives, including postemployment benefit reserves and charges:

In the three months ended June 30, 2017 we announced several restructuring actions in GMIO, primarily related to the withdrawal of Chevrolet in the Indian and South African markets by the end of 2017 and the transition of our South Africa manufacturing operations to Isuzu Motors. We intend to continue manufacturing vehicles in India for sale to certain export markets. In the three months ended June 30, 2017 we recorded charges of $460 million in GMIO primarily consisting of $297 million of asset impairments, sales incentives, inventory provisions and other charges, not reflected in the table above, and $163 million of dealer restructurings, employee separations and other contract cancellation costs, which are reflected in the table above and insignificant costs for separation and other programs in GMNA and GMSA. We expect to complete these programs in 2017.

Other GMIO restructuring programs include separation and other programs in Australia, Korea and India and the withdrawal of the Chevrolet brand from Europe. Collectively these programs had a total cost since inception in 2013 of $866 million and affected a total of approximately 4,690 employees through June 30, 2017. We expect to complete these programs in 2017 and incur insignificant additional restructuring and other charges.

In the three and six months ended June 30, 2016 restructuring and other initiatives related primarily to charges of $240 million in the three months ended March 31, 2016 in GMNA related to the cash severance incentive program to qualified U.S. hourly employees under our 2015 labor agreement with the International Union, United Automobile, Aerospace and Agriculture Implement Workers of America (UAW) and insignificant costs for separation and other programs in Australia, Korea and India and the withdrawal of the Chevrolet brand from Europe.
