Principles of Consolidation and Basis of Presentation

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of Level 3 Communications, Inc. and subsidiaries in which it has a controlling interest. All significant intercompany accounts and transactions have been eliminated. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP").

As part of its consolidation policy, the Company considers its controlled subsidiaries, investments in businesses in which the Company is not the primary beneficiary or does not have effective control but has the ability to significantly influence operating and financial policies, and variable interests resulting from economic arrangements that give the Company rights to economic risks or rewards of a legal entity. The Company does not have variable interests in a variable interest entity.
