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

[2] 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 nine months ended June 30, 2018, and 4 million and 5 million common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would be dilutive. The computation excludes less than 1 million and 1 million of common stock equivalents for the three and nine months ended June 30, 2018, respectively, and less than 1 million and 3 million of common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would have been anti-dilutive.
