NEW YORK (CNNMoney.com) -- State regulators shut down four banks Friday, the Federal Deposit Insurance Corporation said.

The bank were: First Piedmont Bank, based in Winder, Ga.; BankFirst, based in Sioux Falls, S.D.; Temecula Valley Bank of Temecula, Calif.; and Vineyard Bank of Rancho Cucamonga, Calif.

Friday's actions bring the total number of closings for 2009 to 57.

Georgia has claimed 10 of the casualties this year, more than any other state, according to David Barr, spokesperson for the FDIC.

State regulators shut down the four small, regional banks and named the FDIC the receiver.

The FDIC entered into a purchase and assumption agreement with First American Bank and Trust Company, based in Athens, Ga. to take over all of the deposits of First Piedmont Bank. As of July 6, First Piedmont had total assets of $115 million and total deposits of $109 million.

Meanwhile, the FDIC reached an agreement with Alerus Financial, National Association, based in Grand Forks, N.D., to assume all of the deposits of the failed bank in South Dakota. As of April 30, BankFirst had total assets of $275 million and total deposits of $254 million.

Alerus Financial, National Association will take over $72 million in assets of the failed South Dakota bank. The FDIC will retain the remaining assets to dispose of later.

First-Citizens Bank & Trust Company, of Raleigh, N.C., will take over Tumecula Valley's $1.3 billion in deposits.

California Bank & Trust will take over much of Vineyard's $1.6 billion in deposits.

Friday's failures will cost the FDIC fund nearly $1.1 billion, bringing the total cost for failed banks to $13.4 billion this year. That compares with $17.6 billion in all of 2008.

The FDIC, which is funded primarily by fees paid by banks, insures individual deposits up to $250,000.

The number of bank failures so far in 2009 has more than doubled last year's total of 25.
