Accretion Bond
Often the last tranche in a CMO, the accretion
bond, or Z-tranche, receives no cash payments for an extended period of time
until the previous tranches are retired. While the other tranches are
outstanding, the Z-tranche receives credit for periodic interest payments
that increase its face value but are not paid out. When the other tranches
are retired, the Z-tranche begins to receive cash payments that include both
principal and continuing interest.
