Note 5 — Benefit Obligations

The Company provides retirement benefits to certain current and former U.S. employees under defined benefit pension plans, which include a management plan and a represented plan. Benefits under the management plan are based on an adjusted career-average-pay formula or a cash-balance program. Benefits under the represented plan are based on a dollar-per-month formula. Benefit accruals under the management plan were frozen in 2009. Participants in the adjusted career-average-pay program no longer earn service accruals. Participants in the cash-balance program no longer earn service accruals, but continue to earn 4% interest per year on their cash-balance accounts. There are no active participants under the represented plan.

The Company also has a non-qualified supplemental pension plan in the U.S. that principally provides benefits based on compensation in excess of amounts that can be considered under the management plan. In addition, the Company provides post-retirement life insurance coverage under a group life insurance plan for certain U.S. employees. The Company also has pension plans covering certain international employees.
