Note 7. Retirement Plans and Other Postretirement Benefits

Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Employees hired on or after December 8, 2009 are not eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits, a portion of which is in excess of limits imposed on qualified plans by federal tax law. These plans are non-qualified benefit plans. Information on these plans are aggregated and reported under “Retirement Plans” within this footnote.

The Corporation also provides certain postretirement healthcare and life insurance benefits for retired employees. Information on these benefits is reported under “Other Postretirement Benefits” within this footnote.

The Corporation sponsors a Supplemental Non-Qualified Pension Plan which was established in 1981 prior to the existence of a 401(k) deferred salary savings plan, employee stock purchase plan and long-term incentive plans and therefore is not actively offered to new participants.
