MECHANICSBURG, Pa.-Bob Marquette, CEO of Members 1st Federal Credit Union, said the institution will file to act as intervenors in the American Bankers Association lawsuit against NCUA regarding its community charter. “We are very hopeful in fighting the latest banker attack,” Marquette said. He emphasized that the credit union has opened 10 new branches over the last two years it has had the community-based field of membership in good faith. Members 1st's formal response is currently being drafted. NCUA had obtained an extension through Feb. 6 to file a response to the Nov. 1 lawsuit challenging NCUA's application of the local, well-defined community definition. Members 1st was approved for a multiple county field of membership two years ago. “We're serving a lot more people from South Central Pennsylvania than we ever have before and they're the winners,” Marquette said. He added that the credit union's annual member satisfaction survey ranks it regularly in the 98th percentile. No other interested credit union parties have made their intentions in the case public.
