Earnings Per Share [Abstract]

Net loss per share

Net loss per share

Earnings per share is calculated in accordance with ASC Topic 260: "Earnings per Share", which specifies the computation, presentation and disclosure requirements for earnings per share (EPS).  It requires the presentation of basic and diluted EPS.  Basic EPS excludes all dilution and is based upon the weighted average number of shares of common stock outstanding during the period.  Diluted EPS reflects the potential dilution that would occur if convertible securities or other contracts to issue common stock were exercised. At September 30, 2020, there were 989,000 anti-dilutive stock options outstanding compared to 590,000 as of September 30, 2019. At September 30, 2020 there were 375,000 anti-dilutive restricted stock units compared to zero as of September 30, 2019.

The potential effects of 2024 Notes and 2026 Notes conversion features (See "Note 8 - Debt") were excluded from the diluted net loss per share as of September 30, 2020 and September 30, 2019. Potential shares from 2024 Notes and 2026 Notes conversion features at respective maximum conversion rates of 46.40 and 30.84 shares of common stock per $1,000 principal amount of Notes are approximately 638,051 and 3,700,272, respectively.
