Excess Lease Liability

On August 21, 2008, Sonus Pharmaceuticals, Inc., or Sonus, completed a transaction, or the Arrangement, with OncoGenex Technologies whereby Sonus acquired all of the outstanding preferred shares, common shares and convertible debentures of OncoGenex Technologies. Sonus then changed its name to OncoGenex Pharmaceuticals, Inc. Prior to the Arrangement, Sonus entered into a non-cancellable lease arrangement for office space located in Bothell, Washington, which is considered to be in excess of our current requirements. The estimated value of the liability remaining with respect to excess facilities was $4.6 million as of December 31, 2012. In the nine months ended September 30, 2013, with respect to excess facilities, $0.5 million was amortized into income resulting in a remaining liability of $4.1 million at September 30, 2013. The liability is computed as the present value of the difference between the remaining lease payments due less the estimate of net sublease income and expenses and has been accounted for in accordance with the then effective Emerging Issues Task Force No. 95-3, “Recognition of Liabilities in Connection with a Purchase Business Combination.” This represents our best estimate of the liability. Subsequent changes in the liability due to changes in estimates of sublease and occupancy assumptions are recognized as adjustments to the related liability with an offset to restructuring (gain)/loss in future periods.
