net carrying amount
This term might be used to express the combined balances of two accounts. For example, if Equipment has a debit balance of $300,000 and the account Accumulated Depreciation on Equipment has a credit balance of $130,000, we might say that the equipment has a net carrying amount of $170,000. Similarly, if Bonds Payable has a credit balance of $1,000,000 and Premium on Bonds Payable has a credit balance of $8,000, the net carrying amount is $1,008,000. This is similar to book value.
