账面价值carrying value是计入到财务报表当成成本的，那债券的面值FV除了计算coupon一般用不到么？

问题如下：

A company redeems $1,000,000 face value bonds with a carrying value of $990,000. If the call price is 104 the company will:

选项：

reduce bonds payable by $1,000,000.

recognize a loss on the extinguishment of debt of $50,000.

recognize a gain on the extinguishment of debt of $10,000.

解释：

B is correct.

If a company decides to redeem a bond before maturity, bonds payable is reduced by the carrying amount of the debt. The difference between the cash required to redeem the bonds and the carrying amount of the bonds is a gain or loss on the extinguishment of debt. Because the call price is 104 and the face value is $1,000,000, the redemption cost is 104% of $1,000,000 or $1,040,000. The company’s loss on redemption would be $50,000 ($990,000 carrying amount of debt minus $1,040,000 cash paid to redeem the callable bonds).
