[1] The Company did not include Visa Europe's financial results in the Company's unaudited consolidated statements of operations from the acquisition date, June 21, 2016, through June 30, 2016 as the impact was immaterial. The dilutive impact of the outstanding shares of series B and C convertible participating preferred stock from June 21, 2016 through June 30, 2016 was also not included in the calculation of basic or diluted earnings per share as the effect was immaterial. See Note 2—Visa Europe and Note 10—Earnings Per Share to these unaudited consolidated financial statements.

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

[3] The Company did not include Visa Europe's financial results in the Company's unaudited consolidated statements of operations from the acquisition date, June 21, 2016, through June 30, 2016 as the impact was immaterial. The dilutive impact of the U.K.&I and Europe preferred stock from June 21, 2016 through June 30, 2016 was also not included in the calculation of basic or diluted earnings per share as the effect was immaterial.

[4] The Company did not include Visa Europe's financial results in the Company's unaudited consolidated statements of operations from the acquisition date, June 21, 2016, through June 30, 2016 as the impact was immaterial. The dilutive impact of the U.K.&I and Europe preferred stock from June 21, 2016 through June 30, 2016 was also not included in the calculation of basic or diluted earnings per share as the effect was immaterial.

[5] 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 approximately 4 million and 5 million common stock equivalents for the three and nine months ended June 30, 2017, respectively, and 5 million common stock equivalents for the three and nine months ended June 30, 2016, because their effect would be dilutive. The computation excludes less than 1 million of common stock equivalents for the three months ended June 30, 2017 and 3 million of common stock equivalents for the nine months ended June 30, 2017, and 1 million and 2 million of common stock equivalents for the three and nine months ended June 30, 2016, respectively, because their effect would have been anti-dilutive.
