 The Financial Industry Regulatory Authority FINRA said on Thursday that the accord resolves charges that defective procedures at the banks Merrill Lynch unit caused customers holding 13,328 accounts to incur unnecessary sales charges and fees from April 2011 to April 2017. FINRA said some eligible customers failed to receive waivers of front-end sales charges when they bought fund shares after previously selling shares from the same fund family, while others failed to receive rebates of back-end sales fees. Merrill Lynch did not admit or deny wrongdoing.
