WIKIPEDIA:
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.
