Principles of Consolidation

We consolidate the accounts of entities in which we have a controlling financial interest under the voting control model. Investments in entities that we do not control, but have the ability to exercise significant influence over the investee’s operating and financial policies, are accounted for under the equity method. The Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the Unites States of America (“U.S. GAAP”). All intercompany balances and transactions have been eliminated in the Consolidated Financial Statements.

Certain immaterial amounts have been reclassified to conform to current period presentations. Due to the tabular presentation of rounded amounts, certain tables reflect insignificant rounding differences.
