The Company received net proceeds of approximately $28,000 after deducting underwriters’ discounts and commissions and offering costs.

On April 13, 2018, the Company filed a shelf registration statement with the SEC, registering an unlimited amount of debt and/or equity securities that the Company may offer in one or more offerings on terms to be determined at the time of sale. The April 2018 shelf registration statement was automatically effective upon filing and superseded and replaced the Company’s previous shelf registration statement declared effective on April 14, 2015, which was due to expire on April 14, 2018.
