Describing a type of bond or preferred stock that cannot be redeemed or called back by the issuer before a specific date or until it matures.
Investors often prefer noncallable bonds because they provide guaranteed interest payments until maturity.
Noncallable → It is formed from "non-" (meaning not) and "callable" (from the verb "call" meaning to summon or request). The word "noncallable" means not able to be called or summoned, often used in financial contexts to describe bonds that cannot be redeemed before maturity.
Think of 'not' ('non-') being added to 'callable', which means something that cannot be summoned or redeemed.
