The Next put date is the date on which the bondholder has the option to sell the bond back to the issuer at a predetermined price. This feature, known as a put option, allows the bondholder to demand early repayment of the bond before its maturity date. The put next date specifies the first date on which the bondholder can exercise this option.

For investors, the put next date provides a level of flexibility and liquidity. If the bondholder believes that market conditions have changed or if they need to access their investment capital, they can choose to sell the bond back to the issuer on the put next date. This feature can help investors manage risk and potentially exit the investment if needed.
