WASHINGTON ( TheStreet) -- Regulators shut down three banks Friday, bringing the total number of failed institutions this year to 133.

TheStreet.com Ratings had previously given the banks E-minus (Very Weak) financial strength ratings, and all three were included in TheStreet.com's list of undercapitalized banks and thrifts.

The Office of the Comptroller of the Currency closed Republic Federal Bank NA of Miami, Fla. and appointed the Federal Deposit Insurance Corp. receiver. The FDIC sold the failed bank's $353 million in deposits to 1st United Bank of Boca Raton, Fla. for a 1% premium. 1st United also purchased $267 million of Republic Federal's $433 million in total assets at a discount of 37%. The FDIC agreed to share in losses on $210 million of the acquired assets and estimated the cost to its insurance fund would be $122.6 million. Republic Federal's four offices were scheduled to reopen Monday as 1st United branches.

1st United Bank is the main subsidiary of 1st United Bancorp ( FUBC).

The OCC also shut down Valley Capital Bank NA of Mesa, Ariz. The FDIC was appointed receiver and sold the failed bank's total deposits of $41 million for a 2% premium to Enterprise Bank & Trust of Clayton, Mo. Enterprise is held by Enterprise Financial Services ( EFSC).

Enterprise also agreed to take on the failed bank's total assets of $40 million, with the FDIC agreeing to share in losses on about $30 million of the acquired assets. The agency estimated the cost to its insurance fund would be $7.4 million. Valley Capital's office was set to reopen Monday as an enterprise branch.

Kansas regulators shuttered SolutionsBank of Overland Park, Kan., and the FDIC arranged for Arvest Bank of Fayetteville, Ark., to take over the failed institution's $421 million in deposits and $511 in total assets, with Arvest paying no premium. The FDIC agreed to share in losses on $411 million of the acquired assets and estimated the cost to its insurance fund would be $122 million.

The six branches of SolutionsBank were scheduled to reopen during normal business hours on Saturday, as branches of Arvest Bank.

Ongoing Bank Failure Coverage

All previous bank and thrift failures for 2008 and 2009 are detailed in TheStreet.com's interactive bank failure map:

The bank failure map is color-coded, and states that have the largest number of failures are highlighted in red while states with no failures appear in gray. By hovering your mouse over a state you can see that state's combined 2008-2009 bank failure totals. Clicking on a state will open a detailed map that shows the locations of that state's bank failures along with other information.

Although there have been bank and thrift failures in 34 states during 2008 and 2009, four states combined have accounted for more than half of that total:

Georgia leads all states with 29 bank or thrift failures during 2008 and 2009, followed by Illinois with 21, California with 20, and Florida with 15.

Large holding companies acquiring failed institutions during 2008 and 2009 have included J.P. Morgan Chase ( JPM), which acquired Washington Mutual, the largest-ever bank or thrift to fail in the U.S; U.S. Bancorp ( USB); SunTrust Banks ( STI); Regions Financial ( RF); Fifth Third Bancorp ( FITB); Zions Bancorp ( ZION); PNC Financial ( PNC); and BB&T ( BBT).

Free Financial Strength Ratings

The FDIC's temporary increase of agency's basic limit on individual deposit insurance coverage to $250,000 from $100,000 has been extended through 2013. The agency also temporarily waived all deposit insurance limits for business transaction accounts (checking accounts). This waiver is set to expire on June 30, 2010, after which business checking accounts will go back to the $100,000 deposit insurance limit.

After that waiver expires, it will be very important for business and municipal entities such as school districts to carefully monitor the health of their banks. It's very easy to have more than $100,000 of somebody else's money flowing through a business account.

TheStreet.com Ratings issues independent and very conservative financial strength ratings on each of the nation's 8,500 banks and savings and loans. They are available at no charge on the Banks & Thrifts Screener.

In addition, the Financial Strength Ratings for 4,000 life, health, annuity, and property/casualty insurers are available on the Insurers & HMOs Screener.

TheStreet.com Ratings also provides award-winning stock ratings, which are available on the Stock Ratings Screener.

TheStreet.com Ratings was recently ranked the No. 1 independent stock selector during the market meltdown by BNY ConvergEx Group's BNY Jaywalk.
