Contingency related to Technology Solutions Agreement Arbitration
Our wholly owned subsidiaries InterDigital Communications LLC and InterDigital Technology Corporation are engaged in an arbitration relating to a contractual dispute concerning the scope of royalty obligations and the scope of the licenses granted under one of our technology solutions agreements. The arbitration hearing is currently scheduled for late June 2012. As of March 31, 2012, we have deferred related revenue of $33.1 million pending the resolution of this arbitration and recorded such amount within long term deferred revenue since the timing of the final outcome is not known.
