NCUA is issuing a final rule to amend its regulations regarding a federally-insured credit union's obligation to maintain a records preservation program. The final rule clarifies the meaning of catastrophic act and the requirements for preserving vital records. The agency also provides a new Appendix B that offers guidelines for developing a program to prepare for a catastrophic act. NCUA believes the revised rule language and new appendix will facilitate the recovery of essential operations after a catastrophic act resulting in continued member confidence in the credit union system.
