The SEC has imposed a $7.5 million penalty on Merrill Lynch, Pierce, Fenner Smith Inc., the Bank of America brokerage unit, over failures tied to suspicious activity reporting. The enforcement action centers on allegations that Merrill Lynch did not file a sufficient number of suspicious activity reports, or SARs, despite obligations designed to help detect potential money laundering and other illicit activity through customer accounts.

For securities lawyers and compliance professionals, the case is a reminder that anti-money-laundering controls remain a live enforcement priority even when the underlying issue is not an affirmative fraud charge.
