"We are very pleased with our first-quarter financial results, which reflect the highest quarterly net income in MasterCard's history," said Robert W. Selander, MasterCard president and chief executive officer. "These results continue to demonstrate the strength of our business model and growth in electronic forms of payment. Additionally, positive secular trends and business momentum, particularly in international markets, have contributed to a strong start to the year.
"This quarter's strong volume growth, especially in markets within the South Asia/Middle East/Africa and Latin America regions, illustrates the success of our strategy and our ability to leverage our unique assets - our unified global structure, world renowned brands and advanced processing network - worldwide," said Selander.
Total operating expenses increased 8.2%, to $601 million during the first quarter of 2007 compared to the same period in 2006. This was primarily driven by an increase in personnel costs related to the hiring of additional staff to strengthen the company's capability to add value to its customers' businesses, and higher professional fees primarily related to legal costs to defend outstanding litigation. Offsetting this increase was a 2.3% decrease in advertising and market development expenses reflecting a shift in planned spending to later quarters this year. Currency fluctuation contributed approximately 1.9% of the increase in expenses for the quarter.
Total other income was $22 million in the first quarter 2007 versus $10 million in the first quarter of 2006. The increase was primarily driven by a $16 million increase in investment income due to higher rates learned on higher cash and short-term investment balances. MasterCard's effective tax rate of 36.0% for the three months ended March 31, 2007 versus the 34.3% rate experienced in the same period in 2006, increased primarily due to state income tax expense.
