The portion of the carrying value of convertible subordinated debt as of the balance sheet date that is scheduled to be repaid within one year or in the normal operating cycle if longer. This form of debt can be exchanged for a specified amount of another security, typically the entity's common stock, at the option of the issuer or the holder, and places a lender in a lien position behind debt having a higher priority of repayment upon liquidation of the entity's assets.
