Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Investments in affiliates and joint ventures | a) Nuna The Company accounts for the NL Partnership (including its wholly-owned subsidiaries) using proportionate consolidation and accounts for Nuna East Ltd., Nuna West Mining Ltd. and Nuna Pang Contracting Ltd. using the equity method. The NL Partnership holds investments in various affiliates and joint ventures. These entities were formed to perform heavy construction and mining services. The NL Partnership’s involvement with these entities consists of the following activities: assisting in the formation and financing of the entity; providing recourse and/or liquidity support; servicing the assets; providing managerial and administrative services; and receiving fees for services provided. Certain of these entities meet the definition of VIEs. The NL Partnership has consolidated the results of the VIEs in which it is determined to be the primary beneficiary with the recognition of noncontrolling interest, if any, representing amounts attributable to other equity-holders. When the NL Partnership is not considered to be the primary beneficiary of a VIE, it accounts for the investment using either the equity method or proportionate consolidation. When an entity does not meet the definition of a VIE, the voting interest model is applied and it is accounted for using either the equity method or proportionate consolidation. The following table summarizes the investments of the NL Partnership, including the NL Partnership’s ownership interest therein:
