4. Variable Interest Entities
Equatorial Guinea LNG Holdings Limited (EGHoldings), in which Marathon holds a 60 percent interest, was formed for the purpose of constructing and operating an LNG production facility. During facility construction, EGHoldings was a VIE that was consolidated by Marathon because Marathon was its primary beneficiary. Once the LNG production facility commenced its primary operations and began to generate revenue in May 2007, EGHoldings was no longer a VIE. Effective May 1, 2007, Marathon no longer consolidates EGHoldings, despite the fact that the Company holds majority ownership, because the minority shareholders have rights limiting Marathons ability to exercise control over the entity. Marathons investment is accounted for prospectively using the equity method of accounting, is carried at the Companys share of net assets plus loans and advances, which totaled $1.014 billion as of December 31, 2007, and is included in equity method investments in the consolidated balance sheet as of that date. The Andersons Marathon Ethanol LLC, a joint venture in which Marathon and its partner each hold a 50 percent interest and which was formed in 2006 for the purpose of constructing and operating one or more ethanol production plants, is a VIE that is not consolidated. As of December 31, 2007, Marathon had invested $38 million in The Andersons Marathon Ethanol LLC.
