Trumbull-based America’s First Network Credit Union is about to complete one merger and last week applied for another.

Connecticut Banking Commissioner Jorge Perez approved on Jan. 24 America’s First Network Credit Union’s merger with Connecticut Federal Credit Union. The two institutions plan to merge on Feb. 3.

AFNCU’s field of membership will expand to include Connecticut Federal’s membership of about 50 employer groups, including the municipalities of North Haven and North Branford. It’s North Haven branch will remain open following the merger. Connecticut Federal had about $7.87 million in assets as of Sept. 30

The $35.5 million AFNCU on Jan. 21 submitted an application to merge with another institution, Connecticut Transit Federal Credit Union and expand its field of membership to include the Connecticut Transit’s Hartford division employee group. The Hartford-based credit union has about $1 million in total assets.

President and CEO Nick Moalli said AFNCU was excited about the Connecticut Federal merger and the opportunities to help smaller credit unions gain economies of scale.
