NEW YORK (TheStreet) -- Seven new bank failures on Friday -- including three where depositors lost money -- brought the total number of banks and thrifts shut down by regulators this year to 140.

All 165 bank failures since the beginning of 2008 are detailed on TheStreet.com's interactive bank failure map:

The Federal Deposit Insurance Corp.'s four-month streak of finding buyers for all deposits of failed banks and thrifts -- including uninsured balances -- was broken, as the agency failed to find takers for three failed institutions and some depositors took it on the chin.

TheStreet.com

last week outlined the

greater risk depositors face from bank failures

during 2010 because of a return in the second half of the year to regulator deposit insurance limits for non-interest-bearing checking accounts.

Georgia regulators shuttered

RockBridge Commercial Bank

of Atlanta, which had $294 million in assets. Since a buyer couldn't be found for the failed bank's deposits, the FDIC announced that RockBridge's insured deposits would be paid out, with checks mailed on Monday to retail depositors and brokered CDs paid out directly to brokers. The FDIC estimated that there were $2.1 million in deposits that were over insurance limits.

When a bank or thrift fails and uninsured deposits are not acquired, any payouts of uninsured deposits to customers are called dividends. The FDIC receivership may pay an immediate dividend on uninsured deposits, which is called an "advance dividend," and other dividends may be paid as the receivership disposes of the failed institution's assets. No advance dividend was announced. For RockBridge's uninsured depositors. The FDIC estimated the cost of RockBridge Commercial Bank's failure to the deposit insurance fund would be $124 million.

The OTS closed

Peoples First Community Bank

, Panama City, Fla., and the FDIC sold the failed thrift's total deposits of $1.7 billion to

Hancock Bank

of Gulfport, Miss. for a one percent premium. Hancock Bank also took on $1.4 billion of Peoples First Community's $1.8 billion in assets, with the FDIC agreeing to share in losses on the acquired assets and estimated the cost to the deposit insurance fund would be $557 million. Hancock Bank is the main subsidiary of

.

Michigan regulators shut down

Citizens State Bank

of New Baltimore. Once again the FDIC couldn't find a buyer, and announced the creation of

The Deposit Insurance National Bank of New Baltimore

, which would remain open for about 45 days so that Citizen State's insured depositors could move their accounts to other institutions, except for CD and IRA accounts. Customers with these types of accounts were to be mailed checks for their insured balances. The FDIC estimated that approximately $803 thousand in insured deposits might exceed insurance limits. The cost of the failure to the deposit insurance fund was estimated to be $76.6 million.

The OTS closed

New South Federal Savings Bank

of Irondale, Ala. The FDIC was appointed receiver and arranged for

Beal Bank

of Plano, Texas to take over the failed thrift's $1.2 billion in deposits and $1.5 billion in assets. The FDIC estimated the cost of the failure to its insurance fund would be $212 million.

Illinois regulators closed

Independent Bankers' Bank

TheStreet Recommends

of Springfield, an institution that didn't take deposits from the public, instead focusing on providing various services to other banks, including the sale of loan participations. The FDIC formed a "bridge bank" to take over the failed bank's operations and continue providing service to its roughly 450 bank customers, planning to sell the bank. The agency estimated the cost to the insurance fund would be $68.4 million.

The California Department of Financial Institutions closed

Imperial Capital Bank

of La Jolla, which has $2.8 billion in deposits and $4 billion in total assets. The FDIC sold all of the failed bank's deposits for a small premium to City National Bank of Los Angeles, the main subsidiary of

City National Corp.

of Santa Monica, which was Friday's largest failure, with $6.1 billion in total assets and $4.5 billion in deposits. The FDIC arranged for

OneWest Bank was newly-organized in March by an investor group led by Steven Mnuchin before purchasing the remnants of

IndyMac Bank

from the FDIC.

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.
