carrying value of bonds

A bond's face value is fixed, but the amount a company actually shows as owed on its books drifts over the bond's life until, at the very end, it lands exactly on the face value. That moving figure — the number reported on the balance sheet at any given date — is the carrying value of the bond. Think of it as the bond's net balance, starting near the issue price and walking steadily toward face value.

The carrying value (or book value) of a bond is its face value plus any unamortized premium, or minus any unamortized discount. At issuance it equals the cash received: a bond issued at a discount starts below face value, and one issued at a premium starts above it. Each period, as the discount or premium is amortized, the carrying value moves toward the face value. For a discounted bond it rises (face value minus a shrinking discount); for a premium bond it falls (face value plus a shrinking premium). By the maturity date, the discount or premium is fully amortized and the carrying value equals the face value exactly — which is what the company must repay.

Carrying value matters because it is the figure that feeds the interest calculation under the effective-interest method (expense = carrying value times the effective rate) and the amount reported as bonds payable on the balance sheet. It is not the bond's current market price, which moves with interest rates day to day; carrying value follows a predetermined amortization schedule set at issuance. Watching the carrying value climb or descend toward face value is a good check that the amortization is being done correctly.
