(the "Fund") announced the terms of a pro rata offering of transferable rights (the "Rights") to holders of the Fund's common shares, as of the record date of June 19, 2018 ("Record Date Shareholder"), entitling the holders of such rights to subscribe for up to an aggregate of 15,802,094 of the Fund's common shares. Record Date Shareholders received one Right for each outstanding whole common share held on the record date. The Rights entitle their holders to purchase one new common share for every three Rights held; however, any Record Date Stockholder who owns fewer than three common shares as of the Record Date will be entitled to subscribe for one common share. The subscription price per common share is an estimated $16.54 (the "basic subscription privilege"). The Rights Offering also includes an oversubscription privilege, which will entitle holders who fully exercise their basic subscription privilege the right to purchase, at an estimated price of $16.54 per common share, additional common shares of the Fund, subject to availability and pro rata allocation of shares among Record Date Shareholders exercising such oversubscription privilege. The reporting person exercised his basic subscription privilege and oversubscription privilege, and expects to participate in the Fund's allocation of available shares at the close of the subscription period. The subscription rights will expire if they are not exercised by 5:00 p.m. Eastern time on July 18, 2018 (unless otherwise extended). H. Kevin Birzer 2018-07-12
