MasterCard reported other income of $2 million in the third quarter of 2012 versus other income of $28 million in the third quarter of 2011.

The effective tax rate was 27.6% in the third quarter of 2012, versus a rate of 30.5% in the comparable period in 2011.

Year-to-Date 2012 Results For the nine months ended September 30, 2012, MasterCard reported net income of $2.2 billion, or $17.18 per diluted share, excluding a special item taken in the second quarter for an incremental $13 million after-tax charge related to the U.S. merchant litigations.

Net revenue for the nine months ended September 30, 2012 was $5.5 billion, an increase of 10% versus the same period in 2011, or 14% adjusted for currency. Gross dollar volume growth of 16%, transaction processing growth of 27% and cross-border volume growth of 16% contributed to the net revenue growth in the year-to-date period. These factors were partially offset by an increase in rebates and incentives, primarily due to new and renewed customer agreements and increased volumes.
