[1] For the 39 weeks ended October 31, 2020, there were 1.4 million potentially dilutive equity awards and 7.8 million potentially dilutive shares from the Company’s convertible notes that were excluded from the diluted earnings per share calculation because the Company incurred a net loss for this period and their inclusion would be anti-dilutive. For all other periods, anti-dilutive shares relate to stock options and unvested restricted stock.

- Definition

Securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) or earnings per unit (EPU) in the future that were not included in the computation of diluted EPS or EPU because to do so would increase EPS or EPU amounts or decrease loss per share or unit amounts for the period presented.
