SEATTLE, Wash. ( TheStreet) -- State Regulators closed Washington First International Bank of Seattle, Wash. on Friday, bring this year's tally of U.S. bank failures to 82.

The bank was included in TheStreet's Bank Watch List of undercapitalized banks and thrifts, based on first-quarter regulatory data provided by SNL Financial.

Weiss Ratings, formerly TheStreet Ratings, had assigned Washington First International Bank an E-minus (Very Weak) financial strength rating in December, when the rating was downgraded from an E-plus. The December rating was based on third-quarter 2009 financial results, when a $13 million loss left the bank undercapitalized, with a total risk-based capital ratio of 6.94%, below the 8% required for most institutions to be considered adequately capitalized. This ratio declined to 3.37% as of March 31.

After the Washington Department of Financial Institutions took over the bank, the Federal Deposit Insurance Corp. was appointed receiver and sold the failed bank's total deposits of $441 million for a 0.5% premium to East West Bank of Pasadena, Calif., which is the main subsidiary of East West Bancorp ( EWBC - Get Report).

Washington First International Bank had about $521 million in total assets. East West Bank agreed to acquire $501 million of the failed bank's assets, with the FDIC retaining the rest for later disposition. The agency agreed to share in losses on $419 million of the acquired assets, and estimated the cost to the deposit insurance fund would be $158.4 million. Washington First International's four offices were set to reopen during normal business hours as East West branches.

East West Bancorp describes itself as "the largest bank in the nation focused on serving the Asian American community," and this was the holding company's second government-assisted acquisition of a failed bank over the past year, following the purchase of the much larger United Commercial Bank, which failed in November and had $11.2 billion in total assets. East West Bancorp acquired $10.2 billion in assets from the failed bank, with the FDIC sharing in losses on $7.7 billion. East West also picked up 63 U.S. branches from United Commercial, along with offices in China, and another subsidiary institution, UCB-China of Shanghai.
