Compensation and Retirement Disclosure [Abstract]

Pension and Non-pension Postretirement Benefits

We have pension plans covering the majority of our employees. Benefits generally are based on compensation and service for salaried employees and job grade and length of service for hourly employees. In addition, we have an unfunded supplemental employee retirement plan (SERP) that covers certain salaried U.S.-based employees of Libbey hired before January 1, 2006. The U.S. pension plans cover the salaried U.S.-based employees of Libbey hired before January 1, 2006 and most hourly U.S.-based employees (excluding employees hired at Shreveport after December 15, 2008 and at Toledo after September 30, 2010). Effective January 1, 2013, we ceased annual company contribution credits to the cash balance accounts in our Libbey U.S. Salaried Pension Plan and SERP. The non-U.S. pension plans cover the employees of our wholly owned subsidiary in Mexico and are unfunded.

The components of our net pension expense, including the SERP, are as follows:

We have contributed $1.3 million of cash into our pension plans for the three months ended March 31, 2017. Pension contributions for the remainder of 2017 are estimated to be $1.3 million.

We provide certain retiree health care and life insurance benefits covering our U.S. and Canadian salaried employees hired before January 1, 2004 and a majority of our union hourly employees (excluding employees hired at Shreveport after December 15, 2008 and at Toledo after September 30, 2010). Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. Benefits for most hourly retirees are determined by collective bargaining. The U.S. non-pension postretirement plans cover the hourly and salaried U.S.-based employees of Libbey (excluding those mentioned above). The non-U.S. non-pension postretirement plans cover the retirees and active employees of Libbey who are located in Canada. The postretirement benefit plans are unfunded.

The provision for our non-pension postretirement benefit expense consists of the following:
