Employment Benefit Plans Employment Benefit Plans
The Registrant provides a funded, noncontributory qualified pension plan (BNSF Retirement Plan), which covered most non-union employees through March 31, 2019, and an unfunded non-tax-qualified pension plan (BNSF Supplemental Retirement Plan), which covered certain officers and other employees through March 31, 2019. The benefits under these pension plans are based on years of credited service and the highest consecutive sixty months of compensation for the last ten years of salaried employment with the Company. In 2019, the Registrant amended the BNSF Retirement Plan and the BNSF Supplemental Retirement Plan. Non-union employees hired on or after April 1, 2019 are not eligible to participate in these retirement plans and instead receive an additional employer contribution as part of the qualified 401(k) plan based on the employees’ age and years of service. Current plan participants are being transitioned away from the retirement plans and upon transition are eligible for the additional employer contribution.

BNSF Railway also provides a funded, noncontributory qualified pension plan which covers certain union employees of the former The Atchison, Topeka and Santa Fe Railway Company (Union Plan). The benefits under this pension plan are based on elections made at the time the plan was implemented.

With respect to the funded plans, the Registrant's funding policy is to contribute annually not less than the regulatory minimum and not more than the maximum amount deductible for income tax purposes. The BNSF Retirement Plan, the BNSF Supplemental Retirement Plan, and the Union Plan are collectively referred to herein as the Pension Plans.
