Rights Agreement

Effective March 5, 2018, our board of directors terminated the short-term rights plan, implemented on August 31, 2017, that was designed to protect our net operating loss carryforwards. The rights plan, which was previously scheduled to expire following the conclusion of our 2018 annual meeting of shareholders, was terminated based on the reduced value of the rights plan following recent tax law changes and an increase in our stock price since the rights plan was adopted, as well as shareholder feedback.
