(a) In April 2017, we settled the remaining obligation associated with the Hospira U.S. qualified defined benefit pension plan. We purchased a group annuity contract on behalf of the remaining plan participants with a third-party insurance provider. As a result, we were relieved of the $156 million net pension benefit obligation and recorded a pretax settlement gain of $41 million, partially offset by the recognition of actuarial losses and prior service costs upon plan settlement of approximately $30 million in Restructuring charges and certain acquisition-related costs during the second quarter of 2017 (see Note 3).
Schedule of Employer Contributions to Pension and Postretirement Plans | As of and for the nine months ended October 1, 2017, we contributed and expect to contribute in 2017 from our general assets as follows:
|  | Pension Plans |  |
(MILLIONS OF DOLLARS) |  | U.S. Qualified |  | U.S. Supplemental (Non-Qualified) |  | International |  | Postretirement Plans
Contributions from our general assets for the nine months ended October 1, 2017 |  | $ | 1,095 |  |  | $ | 121 |  |  | $ | 134 |  |  | $ | 158 |
Expected contributions from our general assets during 2017(a) |  | $ | 1,095 |  |  | $ | 146 |  |  | $ | 170 |  |  | $ | 204 |
(a) Contributions expected to be made for 2017 are inclusive of amounts contributed during the nine months ended October 1, 2017, including the $1.0 billion voluntary contribution that was made in January 2017 for the U.S. qualified plans, which was considered pre-funding for future anticipated mandatory contributions and is also expected to reduce Pension Benefit Guaranty Corporation variable rate premiums. The U.S. supplemental (non-qualified) pension plan, international pension plan and the postretirement plan contributions from our general assets include direct employer benefit payments.
