Companion bonds

Definition:

A class of a Collateralized Mortgage Obligation (CMO) whose principal is paid off first when the underlying mortgages are prepaid due to falling interest rates. When interest rates rise, there will be lower prepayments of the principal; companion bonds therefore absorb most of the prepayment risk of a CMO.
