¹ Quantities in the following discussion are denoted in whole shares. For the quarter ended June 30, 2021, the quarter ended June 30, 2020 and the six months ended June 30, 2021, approximately 226,000, 71,000 and 214,000 potentially dilutive shares, respectively, were excluded from the computation of net loss per share as their effect would have been anti-dilutive. During the six months ended June 30, 2020, approximately 38,000 shares were excluded from the weighted‑average diluted shares computation as their inclusion would have been anti-dilutive.
