Equity [Abstract] |
Stockholder Rights Plan | Stockholder Rights Plan Under our Stockholder Rights Plan, each share of our common stock generally has “attached” to it one preferred share purchase right. Each right, when exercisable, entitles the holder to purchase 1/1000th of a share of our Junior Participating Preferred Stock Series A at a purchase price of $325.00 (subject to adjustment). Each 1/1000th of a share of Series A Junior Participating Preferred Stock will be substantially equivalent to one share of our common stock and will be entitled to one vote, voting together with the shares of common stock. The rights will become exercisable only if, without the prior approval of the Board of Directors, a person or group of persons acquires or announces the intention to acquire 20% or more of our common stock. If we are acquired through a merger or other business combination transaction, each right will entitle the holder to purchase $300.00 worth of the surviving company’s common stock for $150.00 (subject to adjustment). In addition, if a person or group of persons acquires 20% or more of our common stock, each right not owned by the 20% or greater shareholder would permit the holder to purchase $300.00 worth of our common stock for $150.00 (subject to adjustment). The rights are redeemable, at our option, at $0.01 per right at any time prior to an announcement of a beneficial owner of 20% or more of our common stock then outstanding. The rights expire on December 10, 2019.
