Suppose Ford's defined-benefit pension plan offers a retirement benefit tied to years of service and final salary (like most DB plans) and that the retirement benefit is further increased by a fixed 5% per year each year.Ford plans to change the retirement-plan formula so the amount of the retirement benefit increase is positively correlated to how Ford's stock has performed (rather than the fixed 5% rate).This change in the retirement-benefit formula will cause the appropriate discount rate for the DB plan benefit to:

Increase

Stay the same

Decrease
