Maturity or maturity date refers to the final payment date of a loan or other financial instrument, at which point the principal (and all remaining interest) is due to be paid.
The term maturity is applicable to any form of financial instrument under which the loan is due to be repaid on a fixed date. This includes fixed interest and variable rate loans or debt instruments, whatever they are called, and also other forms of security such as redeemable preference shares, provided their terms of issue specify a maturity date. It is similar in meaning to 'redemption date'. However some such instruments may have no fixed maturity date. Loan stocks with no maturity date continue indefinitely (unless repayment is agreed between the borrower and the lenders at some point) and may be known as 'perpetual stocks'. Some instruments have a range of possible maturity dates, and such stocks can usually be repaid at any time within that range, as chosen by the borrower.
