Accounting for Bonds Issued with Detachable Warrants: Excess of Fair Value and Face Amount

When Lang Co. issued bonds with detachable common stock warrants, the sum of the fair value of the warrants and the face amount of the bonds exceeded the cash proceeds received. This excess is considered additional paid-in capital related to the stock warrants.

Since the fair value of the warrants is known, it represents an additional value to the investors beyond the face amount of the bonds. This additional value is considered a non-cash component of the issuance and is recorded as 'Paid-in Capital in Excess of Par—Stock Warrants'.

Therefore, the correct answer is c. 'Paid-in Capital in Excess of Par—Stock Warrants'.
