Investments	NOTE 6—Investments: During the nine months ended September 30, 2012, we and our joint venture partner each advanced $22.5 million to our 50%-owned joint venture, Saudi Organometallic Chemicals Company (SOCC), pursuant to a long-term loan arrangement whereby the joint venture partners are equally committed to provide partial funding for the construction of SOCC’s aluminum alkyls manufacturing facility. Our loan bears quarterly interest at the London Inter-Bank Offered Rate (LIBOR) plus 1.275% per annum (1.63% as of September 30, 2012), with interest receivable on a semi-annual basis on January 1 and July 1. Principal repayments on amounts outstanding under this arrangement are required as mutually agreed upon by the joint venture partners, but with any outstanding balances receivable in full no later than December 31, 2021. This loan receivable outstanding at September 30, 2012 has been recorded in Other assets in our condensed consolidated balance sheet. The recorded value of this receivable approximates fair value as it bears interest based on prevailing variable market rates. Additionally, during the nine months ended September 30, 2011, we made approximately $10.9 million in capital contributions to SOCC. We have made no additional capital contributions to SOCC during the year 2012. The carrying value of our unconsolidated investment in Stannica LLC, a variable interest entity for which we are not the primary beneficiary, was $5.6 million and $7.3 million at September 30, 2012 and December 31, 2011, respectively. Our maximum exposure to loss in connection with our continuing involvement with Stannica LLC is limited to our investment carrying value.
