A dual currency bond with floating interest rate and an inbuilt put option that provides flexibility and risk management.
An Adjustable Long-Term Putable Security (ALTPS) is a sophisticated financial instrument that combines features of dual currency bonds, floating interest rates, and put options. It is designed to offer investors flexibility and risk management in dynamic market conditions.
