Effective December 1, 2011, we and LP each guaranteed up to $2,200 in support of GreenFiber’s modified and restated loan and security agreement. The guaranty could be drawn on upon an event of default and remained in place through, either, payment of the associated term loan under the security agreement or December 1, 2014, the extended term of GreenFiber’s modified and restated loan and security agreement. In March 2013, we received notification that GreenFiber’s term loan had been called for redemption due to an event of default and as a result we recorded a liability of $2,073, included in other accrued liabilities, as an investment in GreenFiber based on our guaranty. In May 2013, we and LP each contributed $2,073 to GreenFiber to satisfy the guaranty and pay off the term loan in full. Effective June 28, 2013, we and LP each guaranteed up to $750 in support of GreenFiber’s new term loan associated with an amended loan and security agreement. The guaranty can be drawn on upon an event of default by GreenFiber and remains in place through the earlier of payment of the associated term loan under the security agreement and December 1, 2014, which is the extended term of GreenFiber’s amended loan and security agreement. Additionally, as of July 31, 2013, we and LP are each committed to fund any liquidity shortfalls, if any such shortfalls exist, of GreenFiber related to covenant compliance as defined in GreenFiber’s amended loan and security agreement. We have agreed to provide an equity contribution of our pro-rata share of funds, based on ownership percentage, sufficient to cure such shortfall. Tompkins. In May 2011, we finalized the terms of a joint venture agreement with FCR, LLC (“FCR”) to form Tompkins County Recycling LLC (“Tompkins”), a joint venture that operates a material recovery facility (“MRF”) located in Tompkins County, NY and processes and sells commodities delivered to the Tompkins MRF. We account for our 50% membership interest in Tompkins using the equity method of accounting. Our investment in Tompkins amounted to $276 and $257 at July 31, 2013 and April 30, 2013, respectively.
