Computing Amortization of Pension Gain/Loss - Actual return on plan assets was $8,000, and expected return was $10,000. - A gain on the PBO of $4,000 was determined by the actuary at December 31 , based on changes in actuarial assumptions. Required a. Compute amortization of Accumulated OCl_Pension Gain/Loss for the current year using the corridor approach. b. Compute the balance in Accumulated OCl_Pension Gain/Loss on December 31 of the current year. - Note: Use a negative sign to indicate an accumulated loss. c. Compute amortization of Accumulated OCl_Pension Gain/Loss for the next year using the corridor approach. - Note: Round your answer to the nearest whole dollar.
