B的amotization of the premium 和amortization cost 搞错了，哎amortization cost是下降的，因为是bonpayable但是amortization of premium指的就是摊销的本身

The amortization of the premium equals the interest payment minus the interest expense. The interest payment is constant anthe interest expense creases the carrying amount creases. a result, the amortization of the premium increases eayear.premium不是在bon存续期内被摊销完的吗？
amortization of the premium increases eayear. premium is evenly amortizeover the life of the bon B is correct. The amortization of the premium equals the interest payment minus the interest expense. The interest payment is constant anthe interest expense creases the carrying amount creases. a result, the amortization of the premium increases eayear.随着时间的推移，interest和coupon的差异越来越小，amortization of premium为什么会越来越大呢？
