The Board of Directors has approved Adecco's financial statements for 2003. Now that the 2003 audit work is complete, the Company is able to finalise the first quarter 2004 results during the course of this week.

Commenting on the announcement John Bowmer, Executive Chairman of the Board, said: "I am pleased to announce today the completion of both the long and detailed audit work for Adecco's 2003 accounts and the independent investigation by Paul, Weiss with respect to the audit. Ernst & Young has confirmed to the Board that they will deliver an unqualified audit opinion with the full consolidated financial statements prepared in accordance with U.S. GAAP. Furthermore, there has been no restatement of prior year accounts. The identification by our auditors of potential risks which caused this unexpected audit sign off delay was something that the Board and Management took very seriously. Much effort has been and will continue to be expended to ensure that our Company is well managed and further improves its control systems. Having gone through such an exhaustive audit, I am convinced that Adecco emerges a stronger company, ready to face the challenges of the future."

Jerome Caille, Adecco Group Chief Executive Officer added: "We had a solid performance in 2003, converting a 2% sales growth into a 21% increase in operating income, measured in local currency. At the same time, we generated a strong cash flow from operations of EUR 455 million, whilst reducing net debt by EUR 491 million, a reduction of 35% compared to the end of 2002. I would like to congratulate all our teams, who provided jobs for over 2.3 million people in 70 territories in 2003. I would also like to thank them for their outstanding commitment during the recent period to continue to grow our business by delivering the best employment services, and all our customers and associates for their continued confidence in Adecco. This shows the resilience and the strength of the Company, the world leader in Staffing and Career Services. We are now well positioned for continuing growth: sales trends so far this year are above those we observed at the end of last year, and key economic indicators are more positive, giving us confidence that demand for staffing services should pick up further in the rest of the year."

Audit delay

The Adecco Group is expensing the costs associated with the extensive audit work, litigation and investigations as incurred; accordingly, there is no provision for these matters in its 2003 consolidated financial statements. Total costs related to the additional audit fees for Ernst & Young and fees for other advisers in connection with the investigations and related matters are expected to be approximately EUR 100 million of which EUR 6 million has been charged in 2003. The remainder will be charged in 2004 of which approximately EUR 36 million is in Q1 2004.

The Adecco Group and certain of its directors and officers are defendants in consolidated class action lawsuits in the US alleging violations of the federal securities laws in connection with the Adecco Group's public disclosures. The lawsuits, which the Adecco Group intends to defend vigorously, seek an unspecified amount of damages. Regulators in the US and Switzerland are conducting related inquiries. The Adecco Group is cooperating fully with these inquiries.

Timetable

The Company plans to release its Q1 2004 results on June 4, 2004. On that day it will also hold a briefing with respect to the 2003 and Q1 2004 results for financial analysts and a separate media conference call. On June 8, 2004 the Company will make available its 2003 annual report and an invitation to shareholders for the AGM, which is scheduled for June 29, 2004.

Dividend

The Board of Directors proposes a dividend increase of 17% to CHF 0.70 per share (CHF 0.60 for 2002). The dividend for the shares is planned to be paid on July 12, 2004, and the dividend for the ADRs is planned to be paid on August 13, 2004.

Full year 2003 results

Sales

Group sales for the full year were up 2% over 2002 in local currency at EUR 16.3 billion. Sales were down 5% in Euro principally due to the strength of the Euro against most other currencies which reduced reported sales in local currency when translated into Euro by 7%.

In the Adecco Staffing Division, which represents 89% of group revenues, sales were up 2% in local currency but were down 3% in Euro. Sales in local currency in Europe were unchanged with flat sales in France, and growth in Spain, Italy and the UK offset by declines in the Netherlands, Belgium, Germany and Switzerland. In North America, sales in local currency were up 4%, principally due to the US business where sales grew by 5%. In Asia/Pacific sales in local currency were up 11%, with an 11% increase in Japan.

In the Ajilon Professional Division, which represents 10% of group revenues, sales were down by 4% in local currency and by 15% in Euro. Sales in local currency in Europe were down 3% and in North America 7% but increased by 1% in Asia/Pacific.

In the LHH Career Services Division, which represents 1% of group revenues, sales were down by 11% in local currency and by 25% in Euro, reflecting the reduction in demand for outplacement services during the early stages of an economic recovery.

Gross margin

Overall gross margin for the full year decreased by 9% to EUR 2.8 billion. In local currency gross margin was down 2% reflecting a negative currency impact of 7%. Gross margin as a percent of sales was 17.1% compared with 17.8% in 2002, a reduction of 73 basis points (bp). This decline is explained by: negative currency mix changes (18bp), unfavourable change in business mix (11bp), lower average placement fees (12bp) and lower temporary staffing margins (32bp). This 32 bp decrease is attributable to Adecco US (-47 bp), mainly due to an increase in provisions, workers' compensation and state unemployment insurance offset by Adecco France (32 bp) due to a reduction in estimated liability related to payroll tax subsidies, and the remaining decline (-17 bp) is due to all other changes, including a change in mix of higher and lower margin business.

Operating costs

Total operating costs for the full year were reduced to EUR 2.3 billion, representing a reduction of 6% in local currency and 13% in Euro. The ratio of operating costs to sales improved to 13.9% compared with 15.2% last year. Productivity improvements were largely driven by the successful implementation of global cost management initiatives.

Operating income

Operating income before amortisation for the full year was up 21% in local currency to EUR 514 million, representing a return on sales of 3.2%, an improvement of 53 bp over last year's level. Operating income before amortisation measured in Euro was up 14% due to negative currency impact of 7%.

Operating income, after amortisation of intangibles of EUR 9 million, was up 14% in Euro to EUR 505 million, representing a return on sales of 3.1%.

Interest and other expense

Interest expense for the full year decreased by EUR 30 million to EUR 70 million compared to EUR 100 million in 2002 mainly due to a decrease of interest rates and the mix of outstanding debt. Net foreign exchange gains and losses were EUR 9 million in 2003 and EUR 12 million in 2002. Interest income of EUR 11 million was similar to that earned last year with EUR 12 million. Non-operating expenses decreased by EUR 6 million to EUR 2 million in 2003.

Provision for income taxes

The effective tax rate for the full year was 29% compared with 28% last year. The provision for income taxes increased by EUR 31 million to EUR 127 million this year from EUR 96 million last year, mainly due to higher taxable income and the addition of valuation allowances partly offset by favourable tax dispute settlements and other net changes to the tax risk reserve.

It is expected that the effective tax rate for 2004 will increase mainly due to certain additional expenses being benefited at lower tax rates, certain income streams being taxed at higher rates and not benefiting from favourable tax dispute settlements as enjoyed in 2003.

Net income

Net income for the full year was up 26% to EUR 305 million, after charging EUR 3 million for the cumulative effect of change in accounting principle, net of tax (SFAS No. 143 "Asset Retirement Obligations").

Net debt and cash flow

Net debt, defined as short term and long term debt and off-balance sheet debt less cash and marketable securities, was EUR 918 million at the end of the year. This represents a reduction of EUR 172 million during the fourth quarter and a reduction of EUR 491 million or 35% from the level at the end of 2002. Strong operating cash flow of EUR 455 million in 2003 was the major contributor to this reduction.

Divisional performance in 2003

Adecco Staffing

Adecco Staffing is the number 1 in the world, and is ranked number 1 in 9 of the 13 most important staffing markets. This year Adecco Staffing again managed, with sales of EUR 14.4 billion and profits of EUR 511 million, to extend operating gearing converting sales growth of 2% into a profit improvement of 22% in local currency (sales down 3% and profit up 19% in Euro).

-- Adecco France sales were flat in a declining market. Market

outperformance was the result of a focused sales approach.

Profits were positively impacted by a net reduction of EUR 75

million in estimated liability related to payroll tax

subsidies.

-- Adecco USA sales increased by 5% in local currency, but

profitability was adversely affected by increases in

provisions of approximately EUR 50 million, mainly related to

changes in accounting estimates in the billing and payroll

cycles, and high costs for workers' compensation and

unemployment insurance.

-- Adecco UK sales were up 5% in local currency and profitability

increased substantially. Branch network expansion allowed

Adecco UK to capture high margin transactional business and to

be optimally positioned in the fastest growing market

segments.

-- Adecco Japan posted sales growth of 11% in local currency and

profitability improved.

-- Adecco Italy sales were up 5% in local currency and it

succeeded in increasing its client base and maintaining its

market share in a challenging environment in 2003.

-- Adecco Spain posted 7% sales growth, with strong improvement

in profitability.

-- Adecco Switzerland sales were down by 2% in local currency.

Profitability was impacted by a change in business mix

resulting from a decline in permanent placements in 2003, but

the unit succeeded in raising its market share by four

percentage points in 2003 to 28%.

-- Adecco Germany sales were down by 5%, but the business turned

profitable in 2003.

-- Adecco Benelux sales were down by 12% with a decline of 21% in

Adecco Netherlands partially offset by a 4% decline in Adecco

Belgium. Tighter financial controls and specific sales action

plans resulted in an increase in profitability in spite of

declining sales.

Ajilon Professional

Ajilon Professional is ranked world number 3 in the professional staffing market. Ajilon sales were down 4% in local currency at EUR 1.6 billion. Profits were up 35% in local currency at EUR 51 million (sales down 15% and profit up 14% in Euro). In the absence of a recovery in IT and Finance, the segments where Ajilon mainly operates, management focused on maintaining gross margins and on cost containment, resulting in strong profit growth despite a decrease in sales.

LHH Career Services

Lee Hecht Harrison (LHH) is ranked number 2 in the world outplacement and career services market. This division contributed 11% of group profit on only 1% of group sales this year. Sales of EUR 212 million were down 11% in local currency (down 25% in Euro). Profits declined by 15% in local currency to EUR 67 million (down 29% in Euro).

Fourth quarter 2003 results

Sales

Group sales for the fourth quarter were up 3% year on year in local currency at EUR 4.1 billion. Sales were down 3% in Euro due to adverse exchange rate movements which reduced sales overall by 6% in the quarter.

In the Adecco Staffing Division, sales growth was 3% in local currency but was down 2% in Euro. Sales in local currency in Europe were up 3% with growth in France, Spain, Italy, Switzerland and the UK offset by declines in the Netherlands, Belgium and Germany. In North America, sales in local currency were flat, reflecting flat sales in the USA. In Asia/Pacific sales in local currency were up 11%, with an 11% increase in Japan.

In the Ajilon Professional Division, sales were down 9% in Euro, but in local currency, sales were flat showing that Ajilon succeeded in closing the sales gap compared to 2002.

In the LHH Career Services Division, sales were down by 23% in local currency and were down by 35% in Euro, reflecting the further decline in demand for outplacement services during the initial period of an economic recovery.

Gross margin

In the fourth quarter the Group's gross margin was 16.9%, down 18 bp compared to 17.1% in the fourth quarter of 2002.

Operating costs

The Group reduced operating costs this quarter by 4% when measured in local currency and by 11% when measured in Euro. The ratio of operating costs to sales this quarter decreased to 14.4% of sales compared with 15.6% last year.

Operating income

Operating income before amortisation was EUR 103 million this quarter, up 62% in local currency, representing a return on sales of 2.5%, which is 107 bp better than last year's level. Operating income before amortisation measured in Euro was up 70% due to favourable currency mix changes.

Operating income, after amortisation of intangibles of EUR 6 million, was up 66% in Euro to EUR 97 million, representing an overall return on sales of 2.3%.

Interest and other expense

Interest expense decreased by EUR 8 million to EUR 16 million in the fourth quarter of 2003 compared to EUR 24 million in the same period of 2002. Net foreign exchange gains and losses were EUR 2 million in the fourth quarter 2003 and EUR 3 million in the fourth quarter 2002. Interest income in the quarter was EUR 4 million in both years. Non-operating expenses changed from EUR 4 million expenses in the fourth quarter 2002 to EUR 3 million income in the fourth quarter 2003.

Provision for income taxes

The provision for income taxes increased by EUR 26 million to EUR 32 million this quarter from EUR 6 million last year, mainly due to higher taxable income and the addition of valuation allowances partly offset by favourable tax dispute settlements.

Net income

Net income increased in the fourth quarter by 99% to EUR 51 million.

Divisional performance in the fourth quarter 2003

Adecco Staffing

In the fourth quarter Adecco, with sales of EUR 3.7 billion and profits of EUR 119 million, again extended operating gearing converting sales growth of 3% into a profit improvement of 63% in local currency (sales down 2% and profit up 77% in Euro).

-- Adecco France achieved sales growth of 2% consistent with

growth in the market. Profit was positively impacted due to a

reduction in estimated liabilities related to payroll tax

subsidies.

-- Adecco USA sales were flat in local currency but profitability

was adversely affected by increases in provisions of

approximately EUR 50 million, mainly related to changes in

accounting estimates in the billing and payroll cycles.

-- Adecco UK sales were up 8% in local currency and profits were

above last year.

-- Adecco Japan posted sales growth of 11% in local currency and

continues to pursue opportunities for expansion in Japan

following recent regulatory reforms.

-- Adecco Italy sales were up 9%, a further improvement over the

previous quarter.

-- Adecco Spain sales growth recovered to 12% compared with just

2% reported last quarter due to seasonal factors.

-- Adecco Switzerland sales were 5% higher in local currency.

-- Adecco Germany sales were down by 8% but profitability

improved significantly from last year's level. Germany is a

key market for the future and Adecco continues to lead

industry efforts towards a more favourable regulatory

environment.

-- Adecco Benelux sales overall were down by 10% with a decline

in Netherlands of 21% partially offset by 1% sales decline in

Belgium.

Ajilon Professional

Ajilon sales continued to improve when measured in local currency. Sales for the fourth quarter in local currency were flat on last year's fourth quarter at EUR 394 million (down 9% in Euro). Profits were up 74% in local currency at EUR 8 million (up 23% in Euro). In the US, sales in local currency at Ajilon Consulting were down 1% and at Ajilon Finance down 10%. In the UK, sales in local currency at Ajilon Computer People increased by 6% and at Ajilon Office Angels and Roevin sales were flat.

LHH Career Services

This division contributed 11% of group profit on only 1% of group sales. Sales for the quarter of EUR 46 million were down 23% in local currency (down 35% in Euro). Profits declined by 22% to EUR 16 million (down 34% in Euro) in line with sales as the division succeeded in adjusting its cost base to current business levels.

Changes in accounting principles

In 2003 Adecco adopted Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation." For 2003 and future stock-based compensation transactions such as grants of stock options or restricted stock, using the prospective method of SFAS No. 123 will result in compensation expense being amortised through the income statement over the vesting period. The effect of the adoption on the financial statements for the quarter and full year was EUR 6 million additional operating expenses.

A charge of EUR 3 million was recorded for the cumulative effect of change in accounting principle, net of tax following adoption of SFAS No. 143 "Asset Retirement Obligations" related to office leases. There was no equivalent charge in the previous year.

Outlook

Demand for temporary staffing is already accelerating and Adecco expects it to further strengthen later in 2004. In the short term, Adecco expects some margin pressure resulting from competitive pricing as well as a change in business mix with a decrease in sales of the outplacement division. Furthermore, profitability will be impacted by the significant non-recurring costs related to the audit delay during 2004. However, Adecco remains confident about the medium term profitability outlook and expects gross margins to be positively impacted by the increase in the number of permanent placements, the recovery of the professional staffing sector, particularly in IT, and the accelerated growth in deregulated countries with higher margins. Furthermore, the Company's lower cost base and higher productivity will result in a high conversion of top line sales growth into bottom line profitability.
