[1] Net income attributable to Visa Inc. is allocated based on proportional ownership on an as-converted basis. The weighted-average numbers of shares of as-converted class B common stock used in the income allocation were 103 million for the three and six months ended March 31, 2013, and 104 million and 112 million for the three and six months ended March 31, 2012, respectively.

[2] Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on whole numbers, not the rounded numbers presented.

[3] Weighted-average diluted shares outstanding are calculated on an as-converted basis, and include incremental common stock equivalents, as calculated under the treasury stock method. The computation includes 2 million common stock equivalents for the three and six months ended March 31, 2013, and 3 million for the three and six months ended March 31, 2012, because their effect would have been dilutive. The computation excludes less than 1 million common stock equivalents for the three and six months ended March 31, 2013 and 2012, because their effect would have been anti-dilutive.
