Answer:
B) Charge $400,000 to a loss in the year of extinguishment.
Step-by-step explanation:
The $300,000 of amortized discount means that the corporation issued the bonds at a discount and was amortizing the discount over the bond's lifespan. A discount is already a loss, and we must add the $100,000 that the corporation had to pay in excess (premium) to repurchase the bonds. So the total loss resulting from this bond issuance and repurchase was $300,000 + $100,000 = $400,000. Accrual accounting recognizes losses as soon as they happen, so this loss must be recognized as soon as the bonds are repurchased.
