Also found in: Dictionary, Thesaurus.
Certain securities, such as collateralized mortgage obligations (CMOs), are made up of a number of classes, called tranches, that differ from each other because they pay different interest rates, mature on different dates, carry different levels of risk, or differ in some other way.
When the security is offered for sale, each of these tranches is sold separately.
Similarly, a large certificate of deposit (CD) may be subdivided into smaller certificates for sale to individual investors. Each smaller certificate, or tranche, matures on the same date and pays the same rate of interest, but is worth a fraction of the total amount.
A class of securities. Collateralized mortgage backed securities are usually divided into tranches according to seniority and risk.
