Basis of presentation and accounting policies

The Group’s consolidated financial statements are prepared in conformity with accounting principles generally accepted in France.

In the opinion of management, the accompanying consolidated financial statements of the Group contain all adjustments necessary to present fairly, in all material respects, the Group’s consolidated financial position as of March 31, 2005, and the consolidated results of operations and cash flows for the period ended March 31, 2005. All such adjustments are deemed to be of a normal recurring nature. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in Legrand Holding SA’s Annual Report on Form 20-F for the year ended December 31, 2004. The results of operations for the period ended March 31, 2005 are not necessarily indicative of the results to be expected for the full year.

Commitments and contingencies

The Group is involved in a number of legal proceedings and litigations arising in the normal course of business. In the opinion of management, all such matters have been adequately provided for or are without merit, and are of such kind that if disposed of unfavorably, would not have a material adverse effect on the Group's consolidated financial position or results of operations.

Subsequent events

We have no knowledge of any material subsequent events.

a) Application of FAS 142

In July 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards (FAS) No. 141 and 142. These Statements establish new accounting and reporting standards for goodwill and other non amortized intangible assets and in particular, supersede their amortization by an impairment test.

Pursuant to this statement, the group reversed the amortization expenses of goodwill registered under French GAAP (€ 10.9 million).

b) Application of EITF 93-16

In 2001, the Italian subsidiaries revalued their assets, in compliance with the Italian law n° 342 and the decree n°162 (April 13, 2001), retroactively applicable from January 1, 2000. According to EITF 93-16, the tax to be paid in case of distribution of the revalued amount has to be provided for.

c) Derivative financial instruments

Legrand entered into three subordinated securities contracts in 1990 and 1992. In addition, these subordinated securities are hedged by three interest rate swaps. Under French GAAP, these instruments are accounted for as hedges of debt. Under US GAAP, these instruments are recorded at fair value with the changes in fair value recorded to profit and loss.

d) Presentation of the statement of income

To comply with US GAAP, “other expenses” such as restructuring ones are classified as non-operating expenses under French Gaap are requested to be included in the operating income under US Gaap.
