Preferred Stock On October 16, 2015, the Company entered into a Preferred Shares Rights Agreement (“Rights Agreement”) with Computershare Trust Company, N.A., as rights agent, in connection with a dividend distribution declared by the Company’s Board of Directors of one right (“Right”) for each outstanding share of common stock, par value $0.001 (“Common Shares”), per common share of the Company to stockholders of record as of the close of business on October 26, 2015 (“Record Date”). Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Participating Preferred Stock, par value $0.001 per share (“Preferred Shares”), of the Company at an exercise price of $6.69 per one one-thousandth of a Preferred Share, subject to adjustment.
