The exact parameters that establish this core set of U.S. banks, those that will be required to adopt Basel II, will be released in the ANPR next month. There are about ten such banks, and each one has been notified about the requirement.
The U.S. authorities are also proposing to permit any U.S. bank that can meet the infrastructure requirements for the advanced approaches for handling credit and operational risk to choose to follow Basel II capital requirements. Our best guess is that another ten or so banks will choose Basel II capital requirements in this country in the first round.
