11. EQUITY

General—The holders of common stock are entitled to one vote per share on all matters voted on by stockholders, including one vote per nominee in the election of our board of directors (“Board”). Our charter does not provide for cumulative voting in the election of directors.

On May 8, 2019, our Board increased the EVPS of our common stock to $11.10 based substantially on the estimated market value of our portfolio of real estate properties and our third-party investment management business as of March 31, 2019. We engaged a third-party valuation firm to provide a calculation of the range in EVPS of our common stock as of March 31, 2019, which reflected certain balance sheet assets and liabilities as of that date. Previously, on May 9, 2018, our Board increased the EVPS of our common stock to $11.05 from $11.00 based substantially on the estimated market value of our portfolio of real estate properties and our third-party investment management business as of March 31, 2018.

Shares of our common stock are issued under the DRIP, as discussed below, at the same price as the EVPS in effect at the time of issuance.

Dividend Reinvestment Plan—The DRIP allows stockholders to invest distributions in additional shares of our common stock, subject to certain limits. Stockholders who elect to participate in the DRIP may choose to invest all or a portion of their cash distributions in shares of our common stock at a price equal to our most recent estimated value per share.

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.

Share Repurchase Program (“SRP”)—Our SRP provides an opportunity for stockholders to have shares of common stock repurchased, subject to certain restrictions and limitations. The Board reserves the right, in its sole discretion, at any time and from time to time, to reject any request for repurchase.

On August 7, 2019, the Board suspended the SRP with respect to standard repurchases. 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.

Convertible Noncontrolling Interests—Under the terms of the Partnership Agreement, OP unit holders may elect to exchange OP units. The Operating Partnership controls the form of the redemption, and may elect to exchange OP units for shares of our common stock, provided that the OP units have been outstanding for at least one year. As the form of redemption for OP units is within our control, the OP units outstanding as of September 30, 2019 and December 31, 2018, are classified as Noncontrolling Interests within permanent equity on our consolidated balance sheets. The distributions that have been paid on OP units are included in Distributions to Noncontrolling Interests on the consolidated statements of equity. During the nine months ended September 30, 2019, OP units were converted into shares of our common stock at a 1:1 ratio. There were approximately 42.7 million and 44.5 million OP units outstanding as of September 30, 2019 and December 31, 2018, respectively.

Nonconvertible Noncontrolling Interests—In addition to partnership units of the Operating Partnership, Noncontrolling Interests also includes a 25% ownership share of one of our subsidiaries who provides advisory services, which was not significant to our results.
