TechnipFMC is a wholly-owned subsidiary of FMC Technologies, Inc. (“FMCTI”).

Basis of presentation—The consolidated financial statements were prepared in U.S. dollars and in accordance with U.S. generally accepted accounting principles (“GAAP”).

Use of estimates—The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions to be made that may affect the assessment and disclosure of assets and liabilities at the date of the financial statements, as well as the income and the reported expenses regarding this financial year.
