The 2011 plan also permits cash payments under certain conditions.

The expected life represents the weighted average period of time that options granted are expected to be outstanding. The expected life of the options granted to employees and directors is calculated based on the Simplified Method as allowed under Staff Accounting Bulletin No. 110 (“SAB 110”), giving consideration to the contractual term of the options and their vesting schedules, as the Company does not have sufficient historical exercise data at this time. The expected life of the option granted to non-employees equals their contractual term. In the case of an extension of the option life, the calculation was made on the basis of the extended life. D. Compensation Cost for Warrant and Option Issuances The following table sets forth information about the compensation cost of warrant and option issuances recognized for employees and directors: For the year ended December 31, 2019 2018 US$ thousands US$ thousands 286 1,553 The following table sets forth information about the compensation cost of warrant and option issuances recognized for non-employees: For the year ended December 31, 2019 2018 US$ thousands US$ thousands 33 302 The following table sets forth information about the compensation cost of option issuances recognized and capitalized to Unproved Oil & Gas properties: For the year ended December 31, 2019 2018 US$ thousands US$ thousands 3 348 As of December 31, 2019, there was less than $1,000 of unrecognized compensation cost, related to non-vested stock options granted under the Company’s various stock option plans. The cost is expected to be recognized during the year 2020. E. Dividend Reinvestment and Stock Purchase Plan (“DSPP”) On March 27, 2014, we launched our Dividend Reinvestment and Stock Purchase Plan (the “DSPP”) pursuant to which stockholders and interested investors can purchase shares of the Company’s Common Stock as well as units of the Company’s securities directly from the Company. The terms of the DSPP are described in the Prospectus Supplement originally filed on March 31, 2014 (the “Original Prospectus Supplement”) with the Securities and Exchange Commission (“SEC”) under the Company’s effective registration Statement on Form S-3, as thereafter amended. On January 13, 2015, the Company amended the Original Prospectus Supplement (“Amendment No. 3”) to provide for a unit option (the “Unit Option”) under the DSPP comprised of one share of Common Stock and three Common Stock purchase warrants with each unit priced at $4.00. Each warrant afforded the participant the opportunity to purchase the Company’s Common Stock at a warrant exercise price of $1.00. Each of the three warrants series has different expiration dates that have been extended. The warrants first became exercisable on May 2, 2016 and, in the case of ZNWAC on May 2, 2017 and in the case of ZNWAD on May 2, 2018, at a per share exercise price of $1.00. As of May 2, 2017, any outstanding ZNWAB warrants expired. As of May 2, 2018, any outstanding ZNWAC warrants expired. On May 29, 2019, the Company extended the termination date of the ZNWAD Warrant by one (1) year from the expiration date of May 2, 2020 to May 2, 2021. Zion considers this warrant as permanent equity per ASC 815-40-35-2. As such, there is no value assigned to this extension. On November 1, 2016, the Company launched a unit offering (the “Unit Program”) under the Company’s DSPP pursuant to which participants could purchase units comprised of seven shares of Common Stock and seven Common Stock purchase warrants, at a per unit purchase price of $10. The warrant is referred to as “ZNWAE.” The ZNWAE warrants became exercisable on May 1, 2017 and continue to be exercisable through May 1, 2020 at a per share exercise price of $1.00. On May 29, 2019, the Company extended the termination date of the ZNWAE Warrant by one (1) year from the expiration date of May 1, 2020 to May 1, 2021. Zion considers this warrant as permanent equity per ASC 815-40-35-2. As such, there is no value assigned to this extension. The warrant terms provide that if the Company’s Common Stock trades above $5.00 per share at the closing price for 15 consecutive trading days at any time prior to the expiration date of the warrant, the Company may, in its sole discretion, accelerate the termination of the warrant upon providing 60 days advanced notice to the warrant holders. On February 23, 2017, the Company filed a Form S-3 with the SEC (Registration No. 333-216191) as a replacement for the Form S-3 (Registration No. 333-193336), for which the three year period ended March 31, 2017, along with the base Prospectus and Supplemental Prospectus. The Form S-3, as amended, and the new base Prospectus became effective on March 10, 2017, along with the Prospectus Supplement that was filed and became effective on March 10, 2017. The Prospectus Supplement under Registration No. 333-216191 describes the terms of the DSPP and replaces the prior Prospectus Supplement, as amended, under the prior Registration No. 333-193336. On May 22, 2017, the Company launched a new unit offering (the “New Unit Program”). The New Unit Program consisted of a new combination of common stock and warrants, a new time period in which to purchase under the program, and a new unit price, but otherwise the same unit program features, conditions and terms in the Prospectus Supplement applied. The New Unit Program terminated on July 12, 2017. This New Unit Program enabled participants to purchase Units of the Company’s securities where each Unit (priced at $250.00 each) was comprised of (i) the number of shares of Common Stock determined by dividing $250.00 (the price of one Unit) by the average of the high and low sale prices of the Company’s Common Stock as reported on the NASDAQ on the unit purchase date and (ii) Common Stock purchase warrants to purchase an additional 25 shares of Common Stock at a warrant exercise price of $1.00 per share. The warrant is referred to as “ZNWAF.” All ZNWAF warrants became exercisable on August 14, 2017 and continue to be exercisable through August 14, 2020 at a per share exercise price of $1.00. On May 29, 2019, the Company extended the termination date of the ZNWAF Warrant by one (1) year from the expiration date of August 14, 2020 to August 14, 2021. Zion considers this warrant as permanent equity per ASC 815-40-35-2. As such, there is no value assigned to this extension. The warrant terms provide that if the Company’s Common Stock trades above $5.00 per share as the closing price for 15 consecutive trading days at any time prior to the expiration date of the warrant, the Company has the sole discretion to accelerate the termination date of the warrant upon providing 60 days advanced notice to the warrant holders. An Amendment No. 2 to the Prospectus Supplement (as described below) was filed on October 12, 2017. Under Amendment No. 2, the Company initiated another Unit Option Program which terminated on December 6, 2017. This Unit Option Program enabled participants to purchase Units of the Company’s securities where each Unit (priced at $250.00 each) was comprised of (i) a certain number of shares of Common Stock determined by dividing $250.00 (the price of one Unit) by the average of the high and low sale prices of the Company’s Common Stock as reported on the NASDAQ on the unit purchase date and (ii) Common Stock purchase warrants to purchase an additional 15 shares of Common Stock at a warrant exercise price of $1.00 per share. The warrant is referred to as “ZNWAG.” The warrants became exercisable on January 8, 2018 and continue to be exercisable through January 8, 2021 at a per share exercise price of $1.00.
