On November 9, the FDIC proposed two rules which amend the deposit insurance assessment regulations. The proposed rules would: (i) implement a provision in the Dodd-Frank Act that changes the assessment base so that it is based on assets rather than domestic deposits and (ii) change the deposit insurance assessment system for large institutions. The proposed rules would be effective on April 1, 2011. Comments on both proposed rules must be submitted within 45 days of publication in the Federal Register. FDIC Release. FDIC Proposed Rule 1.
