Buckeyes defined benefit pension plan specifies annual retirement benefits equal to: 2.0% × service years × final year’s salary, payable at the end of each year. James was hired by Buckeyes at the beginning of 2004 and is expected to retire at the end of 2033 after 30 years’ service. His retirement is expected to span 20 years. James’ salary is projected to be $250,000 at retirement. The actuary’s discount rate is 6%. At the beginning of 2014, the pension formula was amended to:
1.75% × Service years × Final year’s salary
The amendment was made retroactive to apply the increased benefits to prior service years.

Required:
a. What is the company’s prior service cost at the beginning of 2014 with respect to Davenport after the amendment described above?
b. Since the amendment occurred at the beginning of 2014, amortization of the prior service cost begins in 2014. What is the prior service cost amortization that would be included in pension expense?
c. What is the service cost for 2014 with respect to Davenport?
d. What is the interest cost for 2014 with respect to Davenport?
e. Calculate pension expense for 2014 with respect to Davenport, assuming plan assets attributable to her of $150,000 and a rate of return (actual and expected) of 10%.
