Our redemption plans currently provide that the maximum amount that can be redeemed under the plan is $30,000 worth of securities. Currently, the fixed redemption price is $17.50 per share or unit under the plans which price became effective January 1, 2018. Prior to January 1, 2018, the redemption price was $15.50 per share or unit under the plan.
We may redeem securities under the plans provided the aggregate total has not been exceeded if we have sufficient funds to do so. The plans will terminate in the event the shares become listed on any national securities exchange, the subject of bona fide quotes on any inter-dealer quotation system or electronic communications network or are the subject of bona fide quotes in the pink sheets. Additionally, the Board, in its sole discretion, may terminate, amend or suspend the redemption plans, either or both of them, if it determines to do so in its sole discretion.

NOTE 14 – BENEFICIAL INTEREST

NOTE 15 – DIVIDEND REINVESTMENT PLAN
Our Board of Trustees approved a dividend reinvestment plan to provide existing holders of our common shares with a convenient method to purchase additional common shares without payment of brokerage commissions, fees or service charges. On July 20, 2012, we registered with the Securities Exchange Commission 2,000,000 common shares to be issued under the plan on Form S-3D, which automatically became effective on July 20, 2012. On July 11, 2017, we registered with the Securities Exchange Commission an additional 2,000,000 common shares to be issued under the plan on Form S-3D, which automatically became effective on July 11, 2017.
Under this plan, eligible shareholders can elect to have all or a portion (but not less than 25%) of the cash dividends they receive automatically reinvested in our common shares. If an eligible shareholder elects to reinvest cash dividends under the plan, the shareholder may also make additional optional cash purchases of our common shares, not to exceed $10 per fiscal quarter without our prior approval. The purchase price per common share under the plan equals 95% of the estimated value per common share for dividend reinvestments and equals 100% of the estimated value per common share for additional optional cash purchases, as determined by our Board of Trustees. In addition, participants may not, in any calendar year, purchase or receive via transfer more than $40 in Common Shares derived from the rights granted to Participants under this amendment.
The estimated value per common share was $16.50 and $16.00 at December 31, 2017 and 2016, respectively. See discussion of determination of estimated value in Note 20.
Therefore, the purchase price per common share for dividend reinvestments was $15.68 and $15.20 and for additional optional cash purchases was $16.50 and $16.00 at December 31, 2017 and 2016, respectively. The Board, in its sole discretion, may amend, suspend or terminate the plan at any time, without the consent of shareholders, upon a ten day notice to participants.
In the year ended December 31, 2017, 331,000 shares were issued pursuant to dividend reinvestments and 216,000 shares were issued pursuant to additional optional cash purchases under the plan. In the year ended December 31, 2016, 315,000 shares were issued pursuant to dividend reinvestments and 136,000 shares were issued pursuant to additional optional cash purchases under the plan. In the year ended December 31, 2015, 284,000 shares were issued pursuant to dividend reinvestments and 116,000 shares were issued pursuant to additional optional cash purchases under the plan.
