In the first quarter of 2016, the Company initiated a workforce reduction program to align the size and composition of its workforce with its expected future operating and capital plans. Employee notifications related to the workforce reduction program were completed by June 30, 2016. The Company recognized restructuring charges included in G&A in the Company’s Consolidated Statements of Income of $112 million during the three months ended September 30, 2016, and $363 million during the nine months ended September 30, 2016. All material restructuring charges were recognized in 2016, with the exception of settlement expense expected to be recognized during 2017 for lump-sum payments to terminated participants. During the nine months ended September 30, 2017, the Company recognized restructuring charges of $20 million, primarily related to settlement expense. Settlement expenses for the remainder of 2017 are not expected to be material.
