The Mintos bond has a maturity of 10 years, callable after 5 years. This means that the bond is set to be fully repaid 10 years from its issue date. At maturity, Mintos has to repay the principal (the amount you invested) back to investors. The bond might also be redeemed (called) early by Mintos, but not earlier than 5 years from the issue date.
You have the option to sell your investment in the Mintos bond on the Secondary Market on Mintos.
The 10-year maturity with a call option (early repayment) after 5 years is a common feature for Tier 2 bonds.
