Shareholder Rights Plan
Shareholder Rights Plan	12. Shareholder Rights Plan On December 16, 2016, our Board of Directors declared a dividend of one preferred share purchase right (a "Right") for each share of our common stock outstanding on December 27, 2016. Each Right is attached to and trades with the associated share of common stock. The Rights will become exercisable only if a person or group has acquired 15% or more of our outstanding common stock or announces a tender offer or exchange offer which, if consummated, would result in ownership by a person or group of 15% or more of our outstanding common stock (an "Acquiring Person"). If a person becomes an Acquiring Person, each Right will entitle its holder (other than an Acquiring Person and certain related parties) to purchase for $60 a number of shares of our common stock having a market value of twice such price. In addition, at any time after a person or group acquires 15% or more of our outstanding common stock (unless such person or group acquires 50% or more), our Board of Directors may exchange one share of our common stock for each outstanding Right (other than Rights owned by the Acquiring Person and certain related parties, which would have become void). Any person who, prior to the time of public announcement of the existence of the Rights, publicly disclosed in a Schedule 13D or Schedule 13G (or an amendment thereto) on file with the Securities and Exchange Commission that they beneficially owned 15% or more of our outstanding common stock is not considered to be an Acquiring Person so long as such person does not acquire additional shares in excess of certain limitations. The Rights will expire on August 31, 2018.
