Defined Benefit Plans

CDT Plan

CDT sponsors an unfunded defined benefit pension plan covering substantially all CDT employees (CDT pension plan) which provides for old age, disability and survivors’ benefits. Benefits under the CDT pension plan are generally based on age at retirement, years of service and the employee’s annual earnings. The net periodic cost of this pension plan is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate and estimated service costs. No contributions have been made since the inception of the plan. Actuarial gains or losses in excess of 10% of the projected benefit obligation are being amortized and recognized as a component of net periodic benefit costs over the average remaining service period of the plan's active employees. As of December 31, 2016, there is approximately $0.3 million in accumulated other comprehensive income related to the CDT pension plan that is expected to be recognized as a component of net periodic benefit costs over the remainder of Fiscal 2017.

GXS Germany Plan

As part of our acquisition of GXS in Fiscal 2014, we assumed an unfunded defined benefit pension plan covering certain German employees which provides for old age, disability and survivors' benefits. The GXS GER plan has been closed to new participants since 2006. Benefits under the GXS GER plan are generally based on a participant’s remuneration, date of hire, years of eligible service and age at retirement. The net periodic cost of this pension plan is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate and estimated service costs. No contributions have been made since the inception of the plan. Actuarial gains or losses in excess of 10% of the projected benefit obligation are being amortized and recognized as a component of net periodic benefit costs over the average remaining service period of the plan’s active employees. As of December 31, 2016, there is approximately $80.3 thousand in accumulated other comprehensive income related to the GXS GER plan that is expected to be recognized as a component of net periodic benefit costs over the remainder of Fiscal 2017.

GXS Philippines Plan

As part of our acquisition of GXS in Fiscal 2014, we assumed a primarily unfunded defined benefit pension plan covering substantially all of the GXS Philippines employees which provides for retirement, disability and survivors' benefits. Benefits under the GXS PHP plan are generally based on a participant’s remuneration, years of eligible service and age at retirement. The net periodic cost of this pension plan is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate and estimated service costs. Aside from an initial contribution which has a fair value of approximately $33.1 thousand as of December 31, 2016, no additional contributions have been made since the inception of the plan. Actuarial gains or losses in excess of 10% of the projected benefit obligation are being amortized and recognized as a component of net periodic benefit costs over the average remaining service period of the plan’s active employees. As of December 31, 2016, there is approximately $23.5 thousand in accumulated other comprehensive income related to the GXS PHP plan that is expected to be recognized as a component of net periodic benefit costs over the remainder of Fiscal 2017.

Other Plans

Other plans include defined benefit pension plans that are offered by certain of our foreign subsidiaries. Many of these plans were assumed through our acquisitions or are required by local regulatory requirements. These other plans are primarily unfunded, with the aggregate projected benefit obligation included in our pension liability. The net periodic cost of these plans are determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate and estimated service costs.
