⁽¹⁾	Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers.

⁽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 400 million for the three and six months ended March 31, 2019, and 405 million for the three and six months ended March 31, 2018. The weighted-average number of shares of as-converted class C common stock used in the income allocation was 47 million for the three and six months ended March 31, 2019, and 49 million and 50 million for the three and six months ended March 31, 2018, respectively. The weighted-average number of shares of preferred stock included within participating securities was 32 million of as-converted UK&I preferred stock for the three and six months ended March 31, 2019 and 2018, and 44 million of as-converted Europe preferred stock for the three and six months ended March 31, 2019 and 2018.

⁽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 3 million common stock equivalents for the three and six months ended March 31, 2019 and 4 million common stock equivalents for the three and six months ended March 31, 2018, because their effect would have been dilutive. The computation excludes 1 million of common stock equivalents for the three and six months ended March 31, 2019, and 2 million of common stock equivalents for the three and six months ended March 31, 2018, because their effect would have been anti-dilutive.

⁽⁴⁾

Participating securities include preferred stock outstanding and unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, such as the Company’s UK&I and Europe preferred stock, restricted stock awards, restricted stock units and earned performance-based shares. Participating securities’ income is allocated based on the weighted-average number of shares of as-converted stock.
