Heartland Payment Systems agrees to pay up to $41.4 million to MasterCard Worldwide and card issuers. Settlement comes nearly six months after Heartland reached a $60 million breach settlement with Visa. MasterCard card issuing financial institutions representing at least 80 percent of the claimed-on MasterCard accounts have accepted their offers by June 25. Issuers accepting the offers must agree to certain terms and conditions, including those of the card issuing institutions with 80 percent approval of the offers. The payment is expected during the third calendar quarter of 2010, if they accept their offers.”]
