Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsOn February 20, 2020, HP’s Board of Directors adopted a shareholder rights plan and declared a dividend of one preferred share purchase right for each outstanding share of our common stock to shareholders of record on March 2, 2020. The dividend distribution was made on March 2, 2020. Each right will allow its holder to purchase from HP one one-hundredth of a share of Series A Junior Participating Preferred stock, par value $0.01 per share, for an exercise price of $100, once the rights become exercisable. In the event that a person or group acquires beneficial ownership of 20% or more of our then outstanding common stock, subject to certain exceptions, each right would entitle its holder (other than such person or members of such group) to purchase additional shares of our common stock at a substantial discount to the public market price. In addition, at any time after a person or group acquires 20% or more of our outstanding common stock (unless such person or group acquires 50% or more), The Board may exchange one share of our common stock for each outstanding right (other than rights owned by such person or group, which would have become void). If HP is acquired in a merger or other business combination after an acquiring person acquires 20% or more of HP’s common stock, each holder of the rights would thereafter have the right to purchase, at a substantial discount to the public market price, a number of shares of common stock of the acquiring corporation. The Board may redeem the rights for $0.01 per right, subject to adjustment, at any time before any person or group becomes an Acquiring Person (as defined in the Rights Agreement, dated as of February 20, 2020). The rights will expire on February 20, 2021.
