to its risk-weighted assets. Weights are defined by risk-sensitivity ratios whose calculation is dictated under the relevant Accord. Basel II requires that the total capital ratio must be no lower than 8%. Each national regulator normally has a very slightly different way of calculating bank capital, designed to meet the common requirements within their individual national legal framework. Most developed countries implement Basel I and II, stipulate lending limits as a multiple of a bank's capital eroded by the yearly inflation rate. The five Cs of Credit—Character, Cash Flow, Collateral, Conditions and Covenants—have been replaced by one single criterion. While the international standards of bank capital were established in the 1988 Basel I accord, Basel II makes significant alterations to the interpretation, if not the calculation, of the capital requirement. Examples of national regulators implementing Basel include the FSA in the UK, BaFin in Germany, OSFI in Canada, Banca d'Italia in Italy. In the United States the primary regulators implementing Basel include the Office of the Comptroller of the Currency and the Federal Reserve. In the European Union member states have enacted capital requirements based on the Capital Adequacy Directive CAD1 issued in 1993 and CAD2 issued in 1998. In the United States, depository institutions are subject to risk-based capital guidelines issued by the Board of Governors of the Federal Reserve System (FRB). These guidelines are used to evaluate capital adequacy based primarily on the perceived credit risk associated with balance sheet assets, as well as certain off-balance sheet exposures such as unfunded loan commitments, letters of credit, and derivatives and foreign exchange contracts. The risk-based capital guidelines are supplemented by a leverage ratio requirement. To be adequately capitalized under federal bank regulatory agency definitions, a bank holding company must have a Tier 1 capital ratio of at least 4%, a combined Tier 1 and Tier 2 capital ratio of at least 8%, and a leverage ratio of at least 4%, and not be subject to a directive, order, or written agreement to meet and maintain specific capital levels. To be well-capitalized under federal bank regulatory agency definitions, a bank holding company must have a Tier 1 capital ratio of at least 6%, a combined Tier 1 and Tier 2 capital ratio of at least 10%, and a leverage ratio of at least 5%, and not be subject to a directive, order, or written agreement to meet and maintain specific
