There were an additional aggregate potentially dilutive weighted-average shares of 964,000 from convertible securities outstanding for the three and nine months ended September 30, 2021 and 2020. These securities were not considered in calculating diluted net income per share for the three and nine months ended September 30, 2021 and 2020, as their effect would have been anti-dilutive.
