USCPA 過去問 Lease LiabilityのPV

PVファクターの計算の仕方がいまだにピンとこないんだけど。。。
どんな場合に掛け算をしてどんな場合に割り算をするのか?
 
 
 
Steam Co. acquired equipment under a capital lease for six years. Minimum lease payments were $60,000 payable annually at year end. The interest rate was 5% with an annuity factor for six years of 5.0757. The present value of the payments was equal to the fair market value of the equipment. What amount should Steam report ad interest expense at the end of the first year of the lease?
  • $0
  • $ 3,000
  • $15,227
  • $18,000

 

この問題の場合、60000が毎年年末にPayable。

Annuity factor for 6 years が5.0757

60000 x 5.0757= 304542 これが6年分の支払いの現在価値

これにInterest rate 5%をかけると

304542 x 0.05= 15227 Interest expense at the end of the first year of lease

 

6年分の支払で発生する利息が一年目利息なのか?質問の意図を私が勘違いしているのかなあ
