Answer:
The journal entry is as follows:
On September 30,
Bonds payable A/c Dr. $1,000,000
Loss on bonds retirement A/c Dr. $20,000
To Discount on bond $10,000
To cash A/c $1,010,000
(To record the bonds payable and retirement)
Workings:
Loss on bonds retirement:
= (Cash + Discount on bonds) - Par value of callable bonds
= ($1,010,000 + $10,000) - $1,000,000
= $1,020,000 - $1,000,000
= $20,000
