Subsequent Events [Abstract]
Subsequent Events [Text Block]	SUBSEQUENT EVENT On October 18, 2013 we entered into a settlement agreement with Sigue which provides for a discount on the Sigue Note receivable in exchange for early payment and a release of claims against us pursuant to certain indemnification obligations we have previously undertaken and disclosed as a potential loss contingency. The carrying value as of September 30, 2013, inclusive of the $2.8 million charge taken during the period, represents our best estimate of the fair value of the note based on the terms of the settlement agreement.
