PORTLAND, Ore. - In what would be the largest natural person credit union merger ever, the $1.4 billion Portland Teachers Credit Union and the $650 million Oregon Community Credit Union are discussing a potential merger. As of press time, nothing definitive had been completed. At this point the two boards have just agreed to discuss the possibility. Oregon Community CU is the former U-Lane-O CU. It changed its name earlier this year after converting to a community charter that allows it to serve anyone living or working in 10 counties in Western Oregon. Portland Teachers CU's FOM includes employees of schools and nonprofit educational organizations and their families in five Western Oregon counties. There would be some overlap if a merger deal was completed. Both CUs serve members in the counties of Washington, Multnomah, Yamhill, Columbia and Clackamas.
