This final rule delays the March 31, 2009, implementation date for certain amendments to the Board's capital adequacy guidelines for bank holding companies on trust preferred securities and the definition of capital published by the Board in the Federal Register on March 10, 2005. Due to the continuing stressed conditions in the financial markets and in order to promote stability in the financial markets and the banking industry as a whole, the Board has decided to delay until March 31, 2011, the implementation date of new requirements that: limit the aggregate amount of cumulative perpetual preferred stock, trust preferred securities, and minority interests in the equity accounts of most consolidated subsidiaries (collectively, restricted core capital elements) included in the tier 1 capital of all bank holding companies; require bank holding companies to deduct goodwill, less any associated deferred tax liability, from the sum of core capital elements in calculating the amount of restricted core capital elements that may be included in tier 1 capital; and impose further limits on the amount of restricted core capital elements that internationally active bank holding companies may include in tier 1 capital.
