What Is a Calamity Call?

A CMO is a security that is backed by a pool of mortgages. These products are in some cases known as [Real Estate Mortgage Investment Conduits](/real-estate-mortgage-investment-course remic) (REMICs).

Banks that offer mortgages straightforwardly to home buyers sell those mortgages on to investment firms at a discount from their full value. That clears up cash for the banks to loan out once more. The organizations that buy the mortgages package them available to be purchased to investors as CMOs.

Investors buy CMOs to access the cash flow from mortgages without beginning or purchase the mortgages. CMOs earn their income as the borrowers repay their mortgages, and the repayment fills in as the collateral.
