By Joshua Gallu, Karen Freifeld and Cary O’Reilly Dec. 16 (Bloomberg) — Credit Suisse AG agreed to pay $536 million to settle claims the bank helped process payments that let Iran and other nations avoid government sanctions and gain access to U.S. financial markets. The bank entered into a deferred prosecution agreement as part of the settlement with the U.S. Justice Department, a spokesman for U.S. District Court in Washington said today. The settlement, which included a local prosecutor and the Federal Reserve, relates to a previously disclosed probe of dollar payments from 2002 through April 2007, the bank said today in a statement. “This will be the biggest settlement ever coming to New York,” said Manhattan District Attorney Robert Morgenthau , who in January announced a $350 million agreement with Lloyds TSB Bank Plc for similar acts. “If you violate U.S. sanctions, you’re going to pay a big financial penalty,” he said in an interview yesterday. Morgenthau and U.S. Attorney General Eric Holder scheduled separate news conferences at 4 p.m. today to discuss the case. Credit Suisse, Lloyds and eight other foreign banks have been investigated for “stripping” wire transfer information to conceal illegal money transfers. Credit Suisse altered its dollar payments by removing Iranian names and references from payment messages, according to court documents. The bank used code words for sanctioned entities when executing trades involving U.S. securities and instructed Iranian customers on how to format dollar-denominated payments to evade detection. ‘Alterations, Code Words’ “Credit Suisse knew that without such alterations, amendments and code words, automated (U.S. Department of the Treasury’s Office of Foreign Assets Control) filters at U.S. clearing banks would likely halt the payment messages and securities transactions,” prosecutors said in charging documents. In the agreement, Credit Suisse admitted to “falsifying the records of New York financial institutions,” Morgenthau’s office said in a statement. The bank agreed to train employees who process dollar- denominated payments or securities-trading orders in carrying out United Nations, U.S. and European Union sanctions against Iran. Chief Executive Officer Brady Dougan has until June 30 to certify training is complete, according to the agreement. “Credit Suisse is committed to the highest standards of integrity and regulatory compliance in all its businesses, and takes this matter extremely seriously,” the bank said in the statement. The company “has enhanced its procedures to prevent practices of this type from occurring.” Funds Set Aside Credit Suisse, Switzerland’s biggest bank by market value, had set aside funds anticipating a settlement and may record a charge of 360 million francs ($346 million) in the fourth quarter, the company said. Lloyds used a similar stripping technique to disguise clients in Iran and Sudan who were barred from doing business in the U.S. Lloyds admitted that from 2001 to 2004 it let Iranian banks, including Bank Melli, Bank Saderat and Sepah Bank, and their customers move more than $300 million, the Manhattan District Attorney’s office said in January. Barclays Plc also was cooperating with the probe, according to its 2007 annual report. The London-based lender said results of its internal review are being shared with U.S. agencies. The report said it wasn’t possible to predict the potential effect of any resolution, which could be “substantial,” though wouldn’t have a “material adverse effect.” Kerrie Cohen , a Barclays Capital spokeswoman, declined to comment. ‘Sensitive Countries’ In 2005, Credit Suisse said it wouldn’t enter into any business with clients in “sensitive countries,” terminating relationships when possible and beginning “controlled withdrawal” while fulfilling contractual obligations. The bank terminated business with all parties sanctioned by the U.S. Office of Foreign Assets Control in 2006. As part of the investigation of the banks, prosecutors said they found evidence Iranian interests tried to buy tungsten and other materials used in the guidance systems of long-range missiles. Lloyds wasn’t the bank involved in those attempts, prosecutors said. U.S. laws bar the transfer of funds from Iran and other sanctioned countries without U.S. Treasury Department authorization. The investigation emerged from a probe of the suspicious movement of money by alleged Iranian front companies and charities, Morgenthau said in January. Morgenthau, who turned 90 in July, is retiring as Manhattan District Attorney this month after 34 years. He began as a prosecutor of white-collar crime in 1961, when President John F. Kennedy named him U.S. attorney in New York. He was elected district attorney in 1975. His father, Henry Jr., was Treasury secretary for President Franklin D. Roosevelt . The case is U.S. v. Credit Suisse AG, 09-cr-352, U.S. District Court, District of Columbia (Washington).
