resecuritization

The packaging of a number of existing securitized debt obligations into a new tradable security. Securitized debt obligations may be packaged together either as a collection of similar obligations (collateralized mortgage obligations (CMOs), real estate mortgage investment conduits (REMICs), or commercial mortgage-backed securities (CMBSs)), or in the form of a diversified or mixed class of obligations (credit card loans and mortgage loans). As a rule classes of assets or loans are kept together to assist risk assessment, but creating 'multisector' pools of structured assets in order to provide diversification has become more prevalent. A pool of securitized debts is generally referred to as a collateralized debt obligation (CDO), although a multi-sector securitized pool of debts is also a CDO. Nearly all forms of asset-backed securities (ABSs) and mortgaged-backed securities (MBSs) have found their way into resecuritized CDOs. Also referred to as CDO squared or CDOⁿ, especially when the securitized obligation comprises a variety of underlying obligations (e.g. a number of packages of mortgage loans, car loans and credit card debts, or a mixture of such obligations).  See also mortgage-backed obligation/mortgage-backed security, securitization.
