The money transfer company MoneyGram has agreed to establish a $100 million compensation fund as part of a government settlement over fraud allegations. The company is accused of processing transfers to MoneyGram agents who defrauded customers by posing as family members or offering cash prizes. The Justice Department said thousands of MoneyGram customers complained, but the company failed to fire the agents it knew were involved. MoneyGram also admitted it failed to maintain an effective anti-money-laundering program in violation of federal law.
