The U.S. arm of Canadian banking giant TD Bank Financial on Friday acquired three failed Florida banks, including Riverside National Bank of Florida in Fort Pierce. That brings Florida to nine bank failures so far this year.

Riverside, with 58 branches statewide, had $3.42 billion in assets and $2.76 billion in deposits as of Dec. 31, 2009.

Also failing Friday were AmericanFirst Bank in Clermont, which had $91 million in assets, and First Federal Bank of North Florida in Palatka, which had assets of $393 million.

The Federal Deposit Insurance Corp. entered into a loss-share agreement with TD on $2.2 billion of the failed banks' assets, agreeing to initially share losses on 50-50 basis. The FDIC estimates the failures will cost its deposit insurance fund a combined $508 million.
