Effective July 31, 2000, the Board of Directors amended the Company’s Articles of Incorporation to establish a new series of stock, which is designated as participating preferred stock. The Company’s remaining, undesignated preferred stock may be issued at any time or from time to time in one or more series with such designations, powers, preferences, rights, qualifications, limitations and restrictions (including dividend, conversion and voting rights) as may be determined by the Board of Directors, without any further votes or action by the shareholders. As of December 31, 2015 and 2014, the Company had no preferred stock outstanding.

The net proceeds to us from the public offering, after deducting underwriting discounts and commissions and offering expenses, were $14.7 million. We did not receive any proceeds from the sale of shares by the selling shareholders. In addition, the underwriters elected to exercise an overallotment option for an additional 687,385 shares, and completed the additional sale on January 8, 2013. The net proceeds to us from the overallotment, after deducting underwriting discounts and commission and offering expenses, were $4.1 million.
