Citigroup to pay $100 million in rate-rigging settlement

NEW YORK (Reuters) - Citigroup Inc <C.N> has agreed to pay $100 million (75.3 million pounds) to settle charges by most U.S. states that it rigged the Libor benchmark interest rate to boost profit at the expense of investors.

The settlement was announced by New York State Attorney General Barbara Underwood, whose office has led a probe by 41 U.S. states and Washington, D.C. into rate manipulation by banks.

Libor is short for the London Interbank Offered Rate.
