Dec. 14 (Bloomberg) -- Bank of New York Mellon Corp., the world’s largest custody bank, asked a court to dismiss the New York attorney general’s lawsuit accusing it of defrauding clients in foreign-exchange transactions.

Attorney General Eric Schneiderman sued BNY Mellon in October, saying it misled public and private pension funds about the pricing of currency trades and made $2 billion from the alleged fraud.

The bank, which has been sued by other states and the U.S. Attorney’s Office in Manhattan, yesterday filed a motion to dismiss the complaint, according to a court records website of the New York State Supreme Court. A copy of the filing wasn’t immediately available on the site.

The case is People of the State of New York v. The Bank of New York Mellon Corp., 114735-2009, New York State Supreme Court (Manhattan).
