MasterCard's net income rebounded strongly in the fourth quarter as its overseas business continued to expand, the company said Thursday, Jan. 31, according to AP.

The results benefited by comparison to the year-earlier quarter, which was weighed down by a massive legal charge.

Net income in the three months ended Dec. 31 rose to $605 million, or $4.86 per share, from $19 million, or 15 cents per share, a year earlier.

Net revenue rose 10 percent to $1.90 billion. MasterCard continued to grow by most measures: It processed 20 percent more transactions than a year ago, including 17 percent higher cross-border volumes.

MasterCard is expanding most quickly in Latin America and the region that includes Asia, the Middle East and Africa. Outside the United States, the volume of cash moved in 2012 increased 23.5 percent on a U.S. dollar basis. That compares with growth of 9.7 percent inside the U.S.

The Purchase, N.Y.-based payments network took a charge of nearly $500 million in the year-earlier quarter. The charge covered the cost of a settlement with retailers over the fees they pay on credit card transactions.

For 2012, MasterCard earned $2.76 billion, or $21.94 per share, on revenue of $7.39 billion.

During the quarter, management repurchased 1.3 million shares for $613 million. Repurchasing shares is a way of returning profits to shareholders. It boosts the value of each share that remains in investors' hands.

The quarterly results beat analysts' estimates, sending shares up 4 percent in pre-market trading. Shares rose $18.50 to $534.50 a half-hour before the opening bell.
