LSR Venture [Abstract]
LSR Venture	4. LSR VENTURE In November 2009, the Company became a one-third member in Louisiana Sugar Refining, LLC ("LSR"), a joint venture formed to construct and operate a new cane sugar refinery. Each member contributed $30 million in cash or assets as equity to capitalize the venture. The Company's contribution consisted of land and the existing refinery assets. The Company operated the existing refinery with sales and earnings for its own account until December 31, 2010, during which time the Company completed certain improvements. The equipment and personal property in the existing refinery (other than the small packaging assets) were contributed to LSR on January 1, 2011 resulting in a gain of $3.6 million. After January 1, 2011, the Company continues to operate the small bag packaging facility in Gramercy, with refined bulk sugar purchased annually from LSR under a long term, supply agreement with market-based pricing provisions. The Company contributed the footprint parcel of approximately 7 acres of land for the new refinery at its formation in November 2009. Pursuant to the terms of the operative agreements, LSR and Imperial jointly enrolled the entire site (including the footprint parcel) in the Voluntary Remediation Program (the "VRP") of the LDEQ to conduct an environmental assessment of the site and complete remediation of any identified contamination. The Company is required to pay for the cost of remediation if the VRP uncovers contamination above the applicable industrial standard. Upon completion of the VRP the Company will be released of future environmental liabilities to state and federal authorities. The Company has completed the VRP site investigation and risk assessment and has submitted a site assessment and risk evaluation report to LDEQ for approval. Following LDEQ approval, the remedial action plan will be developed and submitted to LDEQ for approval and thereafter implementation. The estimated cost to complete the remediation for conditions identified in the site investigation and risk assessment evaluation report has been accrued in our consolidated financial statements. Operating losses incurred by LSR, plus additional working capital requirements caused by high sugar prices, strained the joint venture's financial capabilities, necessitating a capital injection by the partners. Rather than make this additional capital contribution, the Company chose to sell its equity stake in LSR and certain idle Louisiana real estate parcels to our partners in December 2011 for $18 million, including $14.2 million at closing, with the remainder payable over 21 months. In connection with the sale, the Company contributed the remaining refinery land to LSR and remains obligated to complete the VRP. We will continue to package sugar at Gramercy under a revised sugar supply agreement with a minimum term of five years. The Company reduced the carrying value of its investment in LSR to net realizable value.
