The carrying value of convertible subordinated debt due to an affiliate in 2029, which includes the current and noncurrent portion, as of the balance sheet date. The preferred securities of the affiliate, originally issued in a public offering, may be exchanged, at the option of the holder of such securities, into a specified amount of this debt. This form of debt can then be converted for a specified amount of the Company's common stock, at the option of the debt holder, and places a lender in a lien position behind debt having a higher priority of repayment in liquidation of the entity's assets.
