The case against Citigroup involved recommendations and sales of Class B and Class C shares of mutual funds. On June 6, 2007, FInRA announced more than $15 million in fines and restitution against Citigroup Global Markets, Inc., to settle charges related to misleading documents and inadequate disclosure in retirement seminars and meetings for BellSouth Corp. employees in North Carolina and South Carolina. FInRA found that Citigroup did not properly supervise a team of brokers located in Charlotte, N.C., who used misleading sales materials during dozens of seminars and meetings for hundreds of BellSouth employees. In July 2010, Citigroup agreed to pay $75 million to settle civil charges that it misled investors over potential losses from high-risk mortgages. The U.S. Securities and Exchange Commission said that Citigroup had made misleading statements about the company's exposure to subprime mortgages. In 2007, Citigroup indicated that its exposure was less than $13 billion, when in fact it was over $50 billion. In April 2011, an arbitration panel ordered Citigroup Inc to pay $54.1 million for losses from municipal securities funds that cratered between 2007 and 2008. In August 2012, Citigroup agreed to pay almost $25 million to settle an investor lawsuit alleging the bank misled investors about the nature of mortgage-backed securities. The lawsuit was on behalf of investors who purchased certificates in one of two mortgage-backed securities trusts from Citigroup Mortgage Loan Trust Inc in 2007. In February 2012, Citigroup agreed to pay $158.3 million to settle claims that it falsely certified the quality of loans issued by its CitiMortgage unit over a period of more than six years, so that they would qualify for insurance from the Federal Housing Administration. The lawsuit was initially brought by Sherry Hunt, a CitiMortgage employee. On February 9, 2012, it was announced that the five largest mortgage servicers (Ally/GMAC, Bank of America, Citi, JPMorgan Chase, and Wells Fargo) agreed to a historic settlement with the federal government and 49 states. The settlement, known as the National Mortgage Settlement (NMS), required the servicers to provide about $26 billion in relief to distressed homeowners and in direct payments to the states and the federal government. This settlement amount makes the NMS the second largest civil settlement in U.S. history, only trailing the Tobacco Master Settlement Agreement. The five banks were also required to comply with 305 new mortgage servicing standards. Oklahoma held out and agreed to settle with the banks separately.
