Commercial Mortgage-Backed Security
A mortgage-backed security in which the mortgages on commercial building, offices, factories, apartments, and other buildings other than single-family homes collateralize the security. Unlike most other mortgage-backed securities, the structure of a CMBS is not standardized and as a result, it is difficult to assess its risk. It is also called a collateralized mortgage-backed security.
