The NASD intensified its focus on mutual fund sales and trading issues, as it brought 12 disciplinary actions having to do with dishonest market timing, late trading unsuitable sales of Class B and Class C mutual fund shares and impermissible revenue sharing. Six major firms were fined this past year - Citigroup Global Markets, American Express Financial Advisors, Chase Investment Services, Merrill Lynch, Wells Fargo, and Linsco/Private Ledger - totaling more than $40 million for unsuitable B share and C share sales. In regards to firms that provided preferential treatment to select mutual funds, NASD settled 27 cases, the largest being against Ameriprise Financial Services, which was fined $12.3 million. The rest of the six firms paid almost $55 million in fines.
