Credit Suisse Group said it expects to pay $536 million to settle a five-year investigation involving parties subject to U.S. economic sanctions and their access to the U.S. banking system.

The settlement would involve the New York County District Attorney's Office, the U.S. Department of Justice, the Federal Reserve Board, the Federal Reserve Bank of New York and the Office of Foreign Assets Control.

The Swiss company said it previously conducted an internal review of some U.S. payments involving countries, individuals and entities that could be subject to U.S. sanctions. In December 2005, the company decided to end the business in question and undertook an independent investigation into the Zurich-based payment activity and other practices.

By 2006, Credit Suisse ended its business with all Office of Foreign Assets Control parties, including closing an office in Tehran.

Credit Suisse first disclosed the probe in 2007. A company spokesman declined to comment beyond the press release.
