Review of models, stress testing and back testing
Article 49
1
A CCP shall regularly review the models and parameters adopted to calculate its margin requirements, default fund contributions, collateral requirements and other risk control mechanisms.

The CCP shall obtain independent validation, shall inform
the Bank of England
of the results of the tests performed and shall obtain
its
validation in accordance with paragraphs 1a,
... 1d and 1e before adopting any significant change to the models and parameters.

Bank of England
for validation of that change. The CCP shall enclose an independent validation of the intended change to its applications. The
Bank of England
shall
...
confirm the receipt of the complete application to the CCP.
