Equity Investments	16. Equity Investments Pirelli Joint Venture On February 19, 2013, the Company entered into a joint venture agreement (the "Joint Venture Agreement") with Pirelli & C. Ambiente SpA ("Pirelli") to form a joint venture entity, Eco Emission Enterprise Remeasurement under the laws of Italy (the "Joint Venture"). The Joint Venture Agreement provided that the Company and Pirelli each held 50% of the total issued share capital of the Joint Venture. The Company accounted for its investment in the Joint Venture using the equity method. On November 8, 2013, as a result of slower than anticipated progress in achieving sales objectives initially established for the Joint Venture, the Company and Pirelli agreed to voluntarily dissolve the Joint Venture in accordance with the Joint Venture Agreement. The dissolution was finalized in April 2014, and the majority of the Company's investment balance of $0.1 million was received at that time, with a small balance to be collected following the receipt of value added tax due from the Swedish and Italian governments. TCC Investment In February 2008, the Company entered into an agreement with Tanaka Holdings Co., Ltd. (formerly Tanaka Holdings K.K.), a Japanese company, which, together with its subsidiary Tanaka Kikinzoku Kogyo K.K., is referred to herein as TKK, to form a new joint venture company, TC Catalyst, Inc. ("TCC"), a Japanese corporation. The joint venture is part of the Catalyst division. The Company entered the joint venture in order to improve its presence in Japan and Asia and strengthen its business flow into the Asian market. Initially, the Company and TKK each owned 50% of TCC, and it ownership. In December 2008, the Company sold shares in TCC to TKK reducing its ownership to 30% and also sold to TKK certain intellectual property and associated rights in various countries in Asia (the "Territory") related to heavy duty catalysts used in commercial vehicles and applications. In December 2009, the Company sold to TKK certain intellectual property and associated rights in the Territory related to three-way catalysts, including low-platinum group metal ("PGM") catalysts, for non-commercial light vehicles and zero-PGM three-way catalysts for heavy duty commercial vehicles and applications and non-commercial light vehicles. As part of the transaction, the Company also sold shares in TCC, which reduced its ownership in the joint venture to 5%. The Company remains contractually obligated to fund its portion of the losses of the joint venture based on its ownership percentage, and it has also agreed not to compete in the Territory with TKK or TCC in connection with heavy duty commercial vehicles and applications and light duty vehicles. Subsequent to these arrangements, the Company discovered that an exception allowing it to continue to supply catalysts in Japan to its largest customer had been omitted in an amendment to the original transaction documents with TKK. The Company has shipped approximately $5.6 million of catalysts covered by the agreements since such amendment through December 31, 2014. In this regard, the Company has made a good faith payment of $0.3 million to TKK with respect to such prior shipments. The Company's investment in TCC is accounted for using the equity method as the Company still has significant influence over TCC as a result of having a seat on TCC's board and due to the technological interdependence between TCC and the Company. The Company's share of income and losses of TCC for the periods presented in this report are not significant.
