Securities and Exchange Commission probe against ADECCO SA comes to an end

The Adecco Group, a Forbes 500 company, is a global leader in human resource solutions, delivering flexible staffing and career resources to corporate clients and qualified associates. With a network of 30,000 employees and 6,000 offices in 71 territories, the group connects up to 700,000 associates with business clients each day.

The group comprises three Divisions: Staffing, Ajilon Professional, and LHH Career Services. Adecco S.A. (the "Company"), registered in Switzerland (ISIN: CH0012138605), is the company at the helm of this operation. It is listed on the Swiss Stock Exchange, the New York Stock Exchange, and Euronext Paris.

The Company issues forward-looking statements, which involve risks and uncertainties. Factors that could affect these statements include global GDP trends, demand for temporary work, changes in legislation, US unemployment tax assessments, a French anti-trust investigation, economic recovery, US class action litigation, commercial relationships, disputes, legal proceedings, and intense competition.

It is important to note that actual results could differ materially from the Company's current expectations. The SEC has terminated its investigation of the Company's SA, and no enforcement action has been recommended. However, the Company encourages investors to carefully consider these risks and uncertainties.

For more detailed information regarding the factors and risks associated with the Company's business, investors are advised to refer to the Company's Annual Report on Form 20-F for the year ended December 28, 2003, and other reports filed with or submitted to the U.S. Securities and Exchange Commission.

The supervision over Adecco S.A. on the New York Stock Exchange before the investigation by the US Securities and Exchange Commission was conducted by the New York Stock Exchange (NYSE) itself. The NYSE, as the listing exchange, had the primary regulatory oversight before the SEC's involvement.
