From the FDIC:
The Board of Directors of the Federal Deposit Insurance Corporation today adopted a Notice of Proposed Rulemaking (NPR) that would require insured institutions to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009 and for all of 2010, 2011 and 2012. The FDIC estimates that the total prepaid assessments collected would be approximately $45 billion.
