10. EQUITY

On May 9, 2018, our board of directors increased its estimated value per share of our common stock from $22.75 to $22.80 based substantially on the estimated market value of our portfolio of real estate properties as of March 31, 2018. We engaged a third party valuation firm to provide a calculation of the range in estimated value per share of our common stock as of March 31, 2018, which reflected certain balance sheet assets and liabilities as of that date. Shares of our common stock are issued under the DRIP and redeemed under the Share Repurchase Program (“SRP”), as discussed below, at the same price as the estimated value per share in effect at the time of issuance or redemption.

Distribution Reinvestment Plan—The DRIP allows stockholders to invest distributions in additional shares of our common stock. Stockholders who elect to participate in the DRIP, and who are subject to U.S. federal income taxation laws, will incur a tax liability on an amount equal to the fair value on the relevant distribution date of the shares of our common stock purchased with reinvested distributions, even though such stockholders have elected not to receive the distributions in cash.

In connection with the Merger, the DRIP was temporarily suspended for the month of July 2018, and DRIP participants received their July 2018 distributions in cash rather than in stock. The DRIP resumed in August 2018, with the distribution payable in September.

Share Repurchase Program—Our SRP provides an opportunity for stockholders to have shares of common stock repurchased, subject to certain restrictions and limitations. The cash available for repurchases on any particular date will generally be limited to the proceeds from the DRIP during the preceding four fiscal quarters, less amounts already used for repurchases since the beginning of that period. Our board of directors reserves the right, in its sole discretion, at any time and from time to time, to reject any request for repurchase. In connection with the Merger, we also temporarily suspended the SRP for the month of July 2018 and resumed in August 2018.

During the six months ended June 30, 2018, repurchase requests surpassed the funding limits under the SRP. When we are unable to fulfill all repurchase requests in a given month, we will honor requests on a pro rata basis to the extent funds are available. We will continue to fulfill repurchases sought upon a stockholder’s death, “qualifying disability,” or “determination of incompetence” in accordance with the terms of the SRP. Approximately 0.6 million shares of our common stock were repurchased under our SRP during the six months ended June 30, 2018. Repurchase requests in connection with a stockholder’s death, “qualifying disability,” or “determination of incompetence” were completed in full. The remaining repurchase requests that were in good order were fulfilled on a pro rata basis. As of June 30, 2018, we had approximately 1.1 million shares of unfulfilled repurchase requests, which will be treated as requests for repurchase during future months until satisfied or withdrawn.

Class B Units—The Operating Partnership issues limited partnership units that are designated as Class B units for asset management services provided by PECO. The vesting of the Class B units is contingent upon a market condition and service condition. We had 0.5 million and 0.4 million unvested Class B units outstanding as of June 30, 2018 and December 31, 2017, respectively.
