Revenue at MasterCard was up almost $275 million, or 14.2% to $2.2 billion. Its expenses rose from $799 million to $892 million, a gain of 11.6%. The company noted the reason behind the increased expenses were the result of more rebates and incentives.

"We secured several new agreements, including three of the largest retailers. Wal-Mart and Sam's Club will flip their co-brand portfolios to MasterCard. Target will also shift its co-brand to MasterCard and use our chip and PIN technology across all of its card products as part of a commitment to provide its customers with the most secure payment product," continued Ajay Banga. "At the same time, we continue to invest in technology and acquisitions that will speed our development of mobile and online solutions."
