We have evaluated each of the unconsolidated investments pursuant to current accounting guidance and none qualify for consolidation. Dividends received from our significant unconsolidated investments were $39.6 million, $20.5 million and $25.6 million in 2014, 2013 and 2012, respectively. At December 31, 2014 and 2013, the carrying amount of our investments in unconsolidated joint ventures exceeded the amount of underlying equity in net assets by approximately $7.0 million and $8.4 million, respectively. These amounts represent the differences between the value of certain assets of the joint ventures and our related valuation on a U.S. GAAP basis. As of December 31, 2014 and 2013, $1.0 million and $1.4 million, respectively, remained to be amortized over the remaining useful lives of the assets with the balance of the difference representing primarily our share of the joint ventures’ goodwill. The carrying value of our unconsolidated investment in Stannica LLC, a variable interest entity for which we are not the primary beneficiary, was $6.2 million and $5.5 million at December 31, 2014 and 2013, respectively. Our maximum exposure to loss in connection with our continuing involvement with Stannica LLC is limited to our investment carrying value. Assets of the Benefit Protection Trust, in conjunction with our EDCP, are accounted for as trading securities in accordance with authoritative accounting guidance. The assets of the Trust consist primarily of mutual fund investments and are marked-to-market on a monthly basis through the consolidated statements of income. As of December 31, 2014 and 2013, these marketable securities amounted to $22.2 million and $23.0 million, respectively. During the year ended December 31, 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. Our loan bears quarterly interest at the London Inter-Bank Offered Rate (“LIBOR”) plus 1.275% per annum (1.53% and 1.52% as of December 31, 2014 and 2013, respectively), 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. The recorded value of this receivable approximates fair value as it bears interest based on prevailing variable market rates. We and our joint venture partner also each advanced 28.1 million Riyals (approximately $7.5 million at December 31, 2014) to SOCC during the year ended December 31, 2014, pursuant to a long-term loan arrangement. During the year ended December 31, 2012, we and our joint venture partner each advanced €1.9 million (approximately $2.3 million and $2.6 million at December 31, 2014 and 2013, respectively) to our 50%-owned joint venture, Eurecat S.A., pursuant to a long-term loan arrangement. These loans have been recorded in Other assets in our consolidated balance sheets at December 31, 2014 and 2013.
