The discount rate used for actuarial calculations is 10%,and the rate of return on plan assets is expect to be 8%.Other information related to the plan for 1997 and 1998 follows 1997 1998 service cost $212500 $225000 amortization of PSC 50000 50000 No hanges in assumptions were required during 1997 and 1998.The actual benefit obligation and plan assets were the same as the expected benefit obligation and plan assets for both years. Required 1.Calculate the 1997 and 1998 pension costs for B. 2.Calculate the balance in the accured/prepaid pension costs account at the end of 1998. 1997 1998 ──── ──── 答案: 1. service cost $212500 $225000 interest cost 75000 103750 amortization of PSC 50000 50000 expected return on plan asset (12000) (35568)* ──── ──── pension expense $325500 $343182 *(150000+1200+212500+70098)X8%=35568 2.累計認列退休金費用=325500+343182 = $(668682) 累計提撥基金數=150000+70098+212500 +70098+225000 = 727696 ──── 預付退休金-1998年底 $ 59014 我的問題是:1.為什麼1998年的預期報酬的計算要加入"212500"?? 他不是服務成本嗎? 2.我也不知道為什麼累計提撥基金數要加上1997和1998的服務成本 (212500.225000) 拜託各位高手了!!!!!感恩多謝!!!! --
