Restricted stock units totaling 27,000 and 14,000 shares of common stock, on a weighted-average basis, were outstanding during the three-month and six-month periods ended June 28, 2020. Additionally, because the Company recorded a cumulative net loss during the three-month period ended June 28, 2020, potential common stock equivalents of 3,120,000 were not included in the calculation of diluted net loss per share for this period. There were no anti-dilutive restricted stock units outstanding, on a weighted-average basis, during the three-month and six-month periods ended June 30, 2019, respectively.
