F1 · shares: Shares purchased by an account of which the reporting person was, at the time of purchase, a joint owner with his adult daughter. The reporting person is no longer a joint owner of such account and thus, as of the date of this report, has no beneficial ownership interest in these shares.

F3 · shares: The purchases by the reporting person on October 14, 2019, January 14, 2020, April 14, 2020 and July 14, 2020 were within six months of the sale by the reporting person on February 14, 2020 of 1,000 common shares at a price per share of $30.00. As a result, such purchases were matchable with such sale under Section 16(b) of the Securities Exchange Act of 1934, as amended. The reporting person has disgorged $70.71 to the issuer, representing the full amount of the profit realized in connection with such short swing transactions.

F2 · balance_after: Because the reporting person has no beneficial ownership interest in these shares as of the date of this report, these shares are not included in the total shares owned by the reporting person.
