On August 13, 2020, we entered into a Consent to Assignment and Amendment with BB&T Capital Markets, a division of BB&T Securities, LLC (“BB&T”) and Truist Securities, Inc., pursuant to which Truist Securities, Inc. succeeded to and assumed all the rights and obligations of BB&T under the original BB&T equity distribution agreement and replaced BB&T as a sales agent thereunder. Accordingly, all references to “BB&T Capital Markets, a division of BB&T Securities, LLC” and “BB&T Capital Markets” in the Original Prospectus Supplement shall hereafter be deemed to be deleted and replaced with references to “Truist Securities, Inc.” and “Truist Securities”, respectively. As a result of the events described above, all references in the Original Prospectus Supplement to a “sales agent” or the “sales agents” shall hereafter be deemed to exclude BB&T and to include Truist Securities, Inc. and all references in the Original Prospectus Supplement to the “equity distribution agreements” shall be deemed to mean the original equity distribution agreements, with the original BB&T equity distribution agreement, as amended by the Consent to Assignment and Amendment.
