The computation is shown below:
The amount which is to be recovered is equal to the purchase amount i.e $650,000
The present value of bargain purchase option is
= $150,000 × Present value factor at 6% for 6th period
= $150,000 × 0.704961
= $105,744
The amount to be recovers through periodic lease payment is
= $650,000 - $105,744
= $544,256
And, the annual lease payment is
= Recovered amount through periodic lease payment ÷ Cumulative Present value factor for annuity due at 6% for 6 periods
= $544,256 ÷ 5.212364
= $104,416
