CFR Matrix. To identify the responsibilities of each Party and to avoid gaps or redundancy in the performance of their responsibilities, the Parties have mutually collaborated in developing a CFR Matrix that identifies each Party’s respective responsibilities for each Reliability Standard Requirement and sub- Requirement applicable to the ISO and the TE as TOPs registered with NERC. The Parties have determined their respective responsibilities for each such requirement based upon consideration of past practice, practicality, efficiency and Good Utility Practice. The CFR Matrix is attached as Appendix 3 to this Agreement.
