Multi-employer Defined Benefit Plan

Pension benefits for substantially all of the Company’s Alaska-based employees are provided through the Alaska Electrical Pension Fund (“AEPF”). The Company pays a contractual hourly amount based on employee classification or base compensation to the AEPF. As a multi-employer defined benefit plan, the accumulated benefits

and plan assets are not determined for, or allocated separately to, the individual employer. This plan was not in endangered or critical status during the plan year.

Defined Benefit Plan

The Company has noncontributory defined benefit pension and noncontributory defined medical, dental, vision, and life benefit plans for eligible employees who meet certain eligibility criteria. The majority of benefits under the plans are frozen and the plans no longer allow new participants to join.

The Company recorded the net periodic benefit cost identified below (in thousands):
