Citigroup said it expects to spend $2.7 billion on legal and related charges in the fourth quarter tied to continuing inquiries and investigations, including probes into how the bank has handled foreign-exchange trading, interest-rate setting and anti-money-laundering compliance.

Speaking at an investor conference hosted by Goldman Sachs, Citi chief executive Michael Corbat outlined the expected spending, which shows that the New York bank hasn't yet put legal woes behind it.
