The Spokane-based parent company of AmericanWest Bank said Thursday it had completed its acquisition of Seattle-based Viking Financial Services Corp., the holding company for Viking Bank.

The acquisition, announced on Sept. 8 and approved by Viking shareholders at a Nov. 3 meeting, brings AmericanWest's assets to $2.3 billion.

AmericanWest adds seven Puget Sound locations — South Seattle, West Seattle, Ballard, Bellevue, Bainbridge Island, Poulsbo and Puyallup — to its footprint. It has 70 branches total in Washington, Idaho, California and Utah. Officials said they plan to convert Viking's systems over to AmericanWest in the second quarter of next year.
