[1] Earnings per share calculated based on whole numbers, not rounded numbers.

[2] The computation of weighted-average dilutive shares outstanding included the effect of 3 million and 2 million dilutive shares of outstanding stock awards for the three and six months ended March 31, 2012 and March 31, 2011, respectively. The computation of weighted-average dilutive shares outstanding excluded stock options to purchase less than 1 million shares of common stock for the three and six months ended March 31, 2012 and 2 million for the three and six months ended March 31, 2011 because their effect would have been anti-dilutive.

[3] Net income attributable to Visa Inc. is allocated to each class of common stock on an as-converted basis. The weighted-average number of shares of as-converted class B common stock used in the income allocation were 104 million and 112 million for the three and six months ended March 31, 2012 and 125 million and 126 million for the three and six months ended March 31, 2011, respectively.
