(32)In order to ensure the timely transfer of collateral, counterparties should have efficient operational processes in place. This requires that the processes for the bilateral exchange of collateral are sufficiently detailed, transparent and robust. A failure by counterparties to agree upon and establish an operational framework for efficient calculation, notification and finalisation of margin calls can lead to disputes and failed exchanges of collateral that result in uncollateralised exposures under OTC derivative contracts. As a result, it is essential that counterparties set clear internal policies and standards in respect of collateral transfers. Any deviation from those policies should be rigorously reviewed by all relevant internal stakeholders that are required to authorise those deviations. Furthermore, all applicable terms in respect of operational exchange of collateral should be accurately recorded in detail in a robust, prompt and systematic way.
