Reduction Of Misys Share Ownership [Abstract]
Reduction Of Misys Share Ownership	3. Reduction of Misys Share Ownership On June 9, 2010, Allscripts entered into a Framework Agreement with Misys plc ("Misys"), which was subsequently amended on July 26, 2010 (as amended, the "Framework Agreement"). Pursuant to the Framework Agreement, Allscripts and Misys agreed to reduce Misys' existing indirect ownership interest in Allscripts through a series of transactions, which we refer to as the "Coniston Transactions." As of June 8, 2010, Misys held indirectly 80 million shares of Allscripts' common stock, representing approximately 55% of the aggregate voting power of Allscripts' capital stock. The Coniston Transactions were completed on August 27, 2010; accordingly, Misys' equity stake in Allscripts was reduced to approximately 10% of the outstanding shares of Allscripts common stock. The repurchased stock was retired and the associated excess of the repurchase price over par totaling $679 million was allocated to additional paid-in capital. On November 17, 2010, Kapiti Limited and ACT Sigmex Limited, each a wholly-owned subsidiary of Misys, sold shares of common stock of Allscripts resulting in Misys holding approximately 4% of the outstanding shares of our common stock. On February 24, 2011, Misys announced that it had disposed of its remaining investment in Allscripts common stock.
