collateralize - secure a debt on a collateral collateralization - securing a debt by selling long-term receivables to another company which secures them on the debts
It is necessary for the current and potential future exposures arising from cleared OTC derivatives contracts to be fully collateralised and for the risk of a build-up of the clearing house's exposures beyond the market value of posted collateral to be eliminated in order for cleared OTC derivatives to be granted for a transitional period the same prudential treatment as exchange-traded derivatives.
