Answer:
Carrying value = $780000
Step-by-step explanation:
The carrying value of a bond is the difference between the face value of a bond less any unamortized discounts on the bond or add any unamortized premiums on the bond. As the bond in the question is a discount bond, the carrying value can be calculated as follows,
Carrying value - Discount bond = Face value - Unamortized Discount on bond
Carrying value = 900000 - 120000
Carrying value = $780000
