Net income attributable to NHI shareholders is adjusted to reflect the decline in Nomura’s equity share of earnings of subsidiaries and affiliates for the six and the three months ended September 30, 2019 and 2020, arising from options to purchase common shares issued by subsidiaries and affiliates.

The weighted average number of shares used in the calculation of diluted earnings per share (“EPS”) reflects the increase in potential issuance of common shares arising from stock-based compensation plans issued by the Company and affiliates, which would have minimal impact on EPS for the six and the three months ended September 30, 2019.

The weighted average number of shares used in the calculation of diluted EPS reflects the increase in potential issuance of common shares arising from stock-based compensation plans issued by the Company and affiliates, which would have minimal impact on EPS for the six and the three months ended September 30, 2020.

Antidilutive stock options and other stock-based compensation plans to purchase or deliver 15,496,600 and 15,450,900 common shares were not included in the computation of diluted EPS for the six and the three months ended September 30, 2019 and 2020, respectively.
