Equity [Abstract]
Shareholders' Equity	Shareholders' Equity Common Shares The Company is authorized to issue up to 500,000,000 common shares of beneficial interest, $0.01 par value per share ("common shares"). Each outstanding common share entitles the holder to one vote on all matters submitted to a vote of shareholders. Holders of the Company’s common shares are entitled to receive dividends when authorized by the Company's Board of Trustees. As of December 31, 2020, 46,973,473 common shares were outstanding. In December 2017, we established a $50 million dividend reinvestment and stock purchase plan (the "Prior DRSPP"). We filed a new $50 million shelf registration statement for the dividend reinvestment and stock purchase plan (the "Current DRSPP" and together with the Prior DRSPP, the "DRSPPs") on December 22, 2020 to replace the prior program. Under the DRSPPs, shareholders may purchase additional common shares by reinvesting some or all of the cash dividends received on the Company's common shares. Shareholders may also make optional cash purchases of the Company's common shares subject to certain limitations detailed in the prospectuses for the DRSPPs. During the year ended December 31, 2020, we issued 20,512 shares under the Prior DRSPP at a weighted average price of $8.89, which generated $0.2 million of proceeds. As of December 31, 2020, there were common shares having a maximum aggregate sales price of approximately $50.0 million available for issuance under the Current DRSPP. In December 2017, we established an "At-the-Market-Equity" program (the "Prior ATM Plan") whereby, from time to time, we may publicly offer and sell our common shares having an aggregate offering price up to $100 million by means of ordinary brokers transactions on the New York Stock Exchange (the "NYSE"), in negotiated transactions or in transactions that are deemed to be "at-the-market" offerings as defined in Rule 415 under the Securities Act of 1933, as amended. We filed a $100 million registration statement for a new ATM program (the "ATM Plan") on January 5, 2021 to replace the prior program. At the same time, the Company entered into a sales agreement with Cantor Fitzgerald & Co., Barclays Capital Inc., BMO Capital Markets Corp., BofA Securities, Inc., BTIG, LLC, Citigroup Global Markets Inc., Regions Securities LLC, Stifel, Nicolaus & Company, Incorporated and Wells Fargo Securities as sales agents. In accordance with the terms of the sales agreement, the Company may from time to time offer, and sell shares of its common stock having an aggregate offering price of up to $100 million. During the year ended December 31, 2020, we issued no shares under the Prior ATM Plan. As of December 31, 2020, there were common shares having a maximum aggregate sales price of approximately $100.0 million available for issuance under the ATM Plan. Preferred Shares The Company is authorized to issue up to 100,000,000 preferred shares, $0.01 par value per share. No preferred shares were outstanding at December 31, 2020 and 2019. Operating Partnership Units Holders of common units in the Operating Partnership, if and when issued, will have certain redemption rights, which will enable the unit holders to cause the Operating Partnership to redeem their units in exchange for, at the Company’s option, cash per unit equal to the market price of the Company’s common shares at the time of redemption or for the Company’s common shares on a one-for-one basis. The number of shares issuable upon exercise of the redemption rights will be adjusted upon the occurrence of share splits, mergers, consolidations or similar pro-rata share transactions, which otherwise would have the effect of diluting the ownership interests of limited partners or shareholders. As of December 31, 2020, there were 654,603 vested Operating Partnership LTIP units held by employees and 102,048 Operating Partnership LTIP units held by a former employee.
