The complaint alleges that we have failed to pay Snell & Wilmer fees due to that firm in connection with prior patent prosecution litigation, in an amount of no less than $808,202, plus interest. We are still evaluating the merits of the claim. As of December 31, 2014, we have included in accounts payable in our Consolidated Balance Sheets a balance due to Snell & Wilmer of $808,202.
