Deposit Insurance

Your shares in the Credit Union are federally insured by the National Credit Union Share Insurance Fund (NCUSIF), an arm of National Credit Union Administration (NCUA). Established by Congress in 1970 to insure member share accounts at federally insured credit unions, the NCUSIF is managed by NCUA under the direction of the three-person NCUA Board. Your share insurance is similar to the deposit insurance protection offered by the Federal Deposit Insurance Corporation (FDIC).
