Stockholders' Equity Note Disclosure [Text Block] | Note 11 - Stock rights On September 15, 1999, the Company's Board of Directors declared a dividend of one common stock purchase right (a "Right") for each share of PPIH's common stock outstanding at the close of business on September 22, 1999. The stock issued after September 22, 1999 and before the redemption or expiration of the Rights was also entitled to one Right for each such additional share. Each Right entitled the registered holders, under certain circumstances, to purchase from the Company one share of PPIH's common stock at $25, subject to adjustment. At no time did the Rights have any voting power. On September 15, 2009, the Company entered into the Amendment ("Amendment") to Rights Agreement dated as of September 15, 1999. Among other things, the Amendment extended the term of the Rights Agreement until September 15, 2019 and amended definitions to include positions in derivative instruments related to the Company's common stock as constituting beneficial ownership of such stock. The Rights expired on September 15, 2019.
