(A) Marine support services are conducted worldwide with assets that are highly mobile. Revenues are principally derived from offshore service vessels, which regularly and routinely move from one operating area to another, often to and from offshore operating areas in different continents. Because of this asset mobility, revenues and long-lived assets attributable to the company's international marine operations in any one country are not material. Equity in net assets of non-U.S. subsidiaries is $2.4 billion, $2.1 billion and $1.5 million at March 31, 2010, 2009 and 2008, respectively. Other international identifiable assets include accounts receivable and other balances denominated in currencies other than the U.S. dollar, which aggregate approximately $1.4 million, $1.4 million and $6.8 million at March 31, 2010, 2009, and 2008, respectively. These amounts are subject to the usual risks of fluctuating exchange rates and government-imposed exchange controls.
