Securities: debts: CG treatment of debts: - other debts

Debts which are not debts on a security, and not gilts, are often referred to as `simple debts’. Such debts will not give rise to chargeable gains in the hands of the original creditor. However, chargeable gains may arise in the hands of a later holder of the debt.

There are no specific instructions on how to identify these debts. They are debts which are not gilt-edged securities or debts on a security.
