WASHINGTON (

TheStreet

) -- Three banks failed in Florida on Friday, along with one each in California and Arizona, bringing this year's tally of failed U.S. banks to 78.

All five of the banks that failed on Friday had been previously assigned E-minus (Very Weak) financial strength ratings by

Weiss Ratings

(formerly

TheStreet.com Ratings

), and all five were included in

TheStreet's

Bank Watch List

of undercapitalized banks and thrifts, based on first-quarter regulatory data provided by

SNL Financial

.

Bank of Florida Corporation

State regulators took over all three banking subsidiaries of

Bank of Florida Corp.

( BOFL) and appointed the Federal Deposit Insurance Corp. receiver. The failed institutions were

Bank of Florida - Southeast

of Fort Lauderdale,

Bank of Florida - Southwest

of Naples and

Bank of Florida - Tampa Bay

of Tampa.

The FDIC arranged for

EverBank

of Jacksonville to assume the three closed banks' total combined deposits of $1.3 billion, along with $1.5 billion in total assets. The agency agreed to share in losses on $1.2 billion of the acquired assets. All 13 branches of the failed banks were scheduled to reopen as EverBank branches on Tuesday, after being closed over the holiday weekend.

The FDIC estimated that the combined cost to its deposit insurance fund from the failure of the three Bank of Florida Corp. subsidiaries would be $203 million.

Bank of Florida Corp. had amended its first-quarter financial results on May 18, recognizing additional impaired loans and increasing its first-quarter net loss to $48.2 million from the $33.1 million that had been reported on May 5. A $72 million rights offering -- through which the holding company hoped to stave-off the failure of the three banks by raising additional capital from current shareholders -- was set to expire.

Granite Community Bank, NA

of Los Angeles, the main subsidiary of

City National Corp.

(CYN)

.

In addition to the deposits, City National agreed to acquire Sun West's total deposits of $361 million. The FDIC agreed to share in losses on $280 million of the acquired assets and estimated the cost to the deposit insurance fund would be $96.7 million.
