(1) 
Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers. The number of shares and per share amounts for the prior periods presented have been retroactively adjusted to reflect the four-for-one stock split effected in the fiscal second quarter of 2015. See Note 8—Stockholders' Equity.
(2) 
Net income is allocated based on proportional ownership on an as-converted basis. The weighted-average number of shares of as-converted class B common stock used in the income allocation was 405 million for the three and six months ended March 31, 2015, and 413 million for the three and six months ended March 31, 2014. The weighted-average number of shares of as-converted class C common stock used in the income allocation was 81 million and 84 million for the three and six months ended March 31, 2015, respectively, and 104 million and 105 million for the three and six months ended March 31, 2014, respectively.
(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 approximately 5 million common stock equivalents for the three and six months ended March 31, 2015, and 7 million common stock equivalents for the three and six months ended March 31, 2014, because their effect would be dilutive. The calculation excludes 1 million of common stock equivalents for the three and six months ended March 31, 2015, and 1 million and 2 million of common stock equivalents for the three and six months ended March 31, 2014, respectively, because their effect would have been anti-dilutive.
(4) 
The outstanding number of shares of class B and C common stock was not impacted by the stock split as these stockholders received an adjustment to their respective conversion ratios instead of stock dividends. See Note 8—Stockholders' Equity. Weighted-average basic and diluted shares outstanding for class B and C common stock are calculated based on the common shares outstanding of each respective class rather than on an as-converted basis.
(5) 
Participating securities are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, such as the Company's restricted stock awards, restricted stock units and earned performance-based shares.
