Maturity date is a finance term referring to the date when a principal amount of a note, draft, acceptance bond, or other debt instrument becomes due or payable. It is also a termination or due date on which an installment loan must be paid in full. For example, a bond due to mature on January 1, 2010, will return the bondholder's principal and final interest payment when it reaches its maturity date.
A serial maturity is when bonds are all issued at the same time but come due on different staggered redemption dates. A series maturity is when bonds come due on different dates staggered apart because they were issued at different times. A term maturity date is when all bonds issued come due at the same time.
