Senior Preferred Shares were considered as participating securities under ASC 260, therefore, they are included in the computation of basis shares. Diluted net income per share is computed using the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the respective year. The potentially dilutive ordinary shares included RSUs and options to purchase ordinary shares of 453,592, 2,033,237 and 3,034,385 for the years ended December 31, 2023, 2024 and 2025 on a weighted average basis, respectively.
