The total amount of net periodic benefit cost (credit) for defined benefit plans for the period, excluding any pension and OPEB corridor adjustments separately disclosed, if any. Periodic benefit costs include the following components: service cost, interest cost, expected return on plan assets, gain (loss), prior service cost or credit, transition asset or obligation, and gain (loss) due to settlements or curtailments. Pension and Other Postretirement Benefit (OPEB) corridor charge (credit) represents the charge (credit) recognized during the period, if any, for the accumulated actuarial (gain) loss outside of the corridor of 10% of the pension and other postretirement benefit obligation or plan asset. This is based on the company's accelerated method of recognizing (gains) losses for pension and other postretirement benefit plans.
