Note 14 - Common stock warrants

The Company’s Plan of Reorganization, which was approved by the United States Bankruptcy Court for the Northern District of California on January 11, 2000, provided for the creditors and claimants to receive new warrants in settlement of their claims. The warrants expire May 11, 2038.

All Series A, B, C and D warrants have been called, and all Series A and C warrants have been exercised. All Series B warrants had been exercised at December 31, 2017 however, on January 23, 2018, 117,000 shares of Mentor’s Common Stock purchased in 2014 through warrant exercises by two Bhang shareholders under an agreement that was ultimately rescinded, were returned to the Company and the associated exercise of warrants was reversed with 87,456 Series B warrants and 29,544 Series D warrants reinstated. The Company intends to allow warrant holders or Company designees, in place of original holders, additional time as needed to exercise the remaining series B and D warrants. The Company may lower the exercise price of all or part of a warrant series at any time. Similarly, the Company could reverse split the stock to raise the stock price above the warrant exercise price. The warrants are specifically not affected and do not split with the shares in the event of a reverse split. If the called warrants are not exercised, the Company has the right to designate the warrants to a new holder in return for a $0.10 per share redemption fee payable to the original warrant holders as discussed further in Note 15. All such changes in the exercise price of warrants were provided for by the court in the Plan of Reorganization to provide a mechanism for all debtors to receive value even if they could not or did not exercise their warrant. Therefore, Management believes that the act of lowering the exercise price is not a change from the original warrant grants and the Company did not record an accounting impact as the result of such change in exercise prices.

All Series A and Series C warrants were exercised by December 31, 2014. Exercise prices in effect at January 1, 2015 through September 30, 2019 for Series B warrants were $0.11 and Series D warrants were $1.60.

In 2009, the Company entered into an Investment Banking agreement with Network 1 Financial Securities, Inc. and a related Strategic Advisory Agreement with Lenox Hill Partners, LLC with regard to a potential merger with a cancer development company. In conjunction with those related agreements, the Company issued 689,159 Series H ($7) Warrants, with a 30-year life. The warrants are subject to cashless exercise based upon the ten-day trailing closing bid price preceding the exercise as interpreted by the Company.

As of September 30, 2019 and December 31, 2018 the weighted average contractual life for all Mentor warrants was 18.8 years and 19.5 years, respectively, and the weighted average outstanding warrant exercise price was $2.11 and $2.11 per share, respectively.

During the nine months ended September 30, 2019 and 2018, a total of 0 and 379,436 warrants were exercised, respectively. There were no warrants issued during the periods ended September 30, 2019 and 2018. In January 2018, the 2014 exercise of 87,456 Series B warrants and 29,544 Series D warrants by two Bhang shareholders under an agreement that was ultimately rescinded, were reversed and reinstated. The intrinsic value of outstanding warrants at September 30, 2019 and December 31, 2018 was $5,247 and $20,115, respectively

The following table summarizes Series B and Series D common stock warrants as of each period:

Series E, F, G and H warrants were issued for investment banking and advisory services during 2009. Series E, F and G warrants were exercised in 2014. The following table summarizes Series H ($7) warrants as of each period:

On February 9, 2015, in accordance with Section 1145 of the United States Bankruptcy Code and the Company’s Plan of Reorganization, the Company announced a minimum 30-day partial redemption of up to 1% (approximately 90,000) of the already outstanding Series D warrants to provide for the court specified redemption mechanism for warrants not exercised timely by the original holder or their estates. Company designees that applied during the 30 days paid 10 cents per warrant to redeem the warrant and then exercised the Series D warrant to purchase a share at the court specified formula of not more than one-half of the closing bid price on the day preceding the 30-day exercise period. In the Company’s October 7, 2016 press release, Mentor stated that the 1% redemptions which were formerly priced on a calendar month schedule would subsequently be initiated and be priced on a random date schedule after the prior 1% redemption is completed to prevent potential third-party manipulation of share prices at month-end. The periodic partial redemptions will continue to be periodically recalculated and repeated until such unexercised warrants are exhausted, or the partial redemption is otherwise paused, suspended or truncated by the Company. For the nine months ended September 30, 2019, no warrants were redeemed. In 2018, the Company allowed for a partial redemption of 63,161 Series D warrants at an exercise price per warrant of $0.35 plus a $0.10 warrant redemption fee per warrant and an additional 379,436 Series D Warrants were exercised at their full exercise price of $1.60 plus the $0.10 warrant redemption fee per warrant. The regular warrant exercises and 1% partial redemption authorization, which were recalculated and repeated according to the court formula, resulted in a combined average exercise price of $1.42 per share for the year ended December 31, 2018.
