Chéserex, Switzerland – March 2, 2007: The Adecco Group, the worldwide leader in Human Resource services, today announced results for the full year 2006 as well as for the fourth quarter. For the full year net income increased by 35% to EUR 611 million compared to EUR 453 million a year earlier. Revenues were up 12% to EUR 20.4 billion from EUR 18.3 billion in 2005.

Dieter Scheiff, Chief Executive Officer, Adecco Group said: “In 2006 Adecco delivered strong results. With 9% organic revenue growth we reached the upper end of our growth target. During the year we have made good progress in enhancing the gross margin, while maintaining disciplined cost management. This led to an encouraging operating income margin improvement of 60 bps to 4.0% in 2006.”

“Our value oriented management approach and focus on professional and specialised staffing, combined with the continued favourable economic environment for the industry as a whole, make me optimistic about Adecco’s future growth and returns. We are well on track to reach our long-term goals of 7 to 9% annual revenue growth, as well as an operating margin of over 5% and a return on capital employed of above 25% by 2009.”

FY 2006 and Q4 2006 FINANCIAL PERFORMANCE

Revenues

Group revenues for the fiscal year of 2006 were EUR 20.4 billion, a 12% increase or a 9% increase organically compared to the fiscal year 2005. Revenues for the fourth quarter increased to EUR 5.3 billion, which is an 8% rise on a reported and organic basis.

Gross Profit

Gross margin in the full year 2006 improved 50 bps to 17.4% versus 2005 due to a combination of acquisitions, higher permanent placement revenues and good growth in the higher margin professional business. In the fourth quarter, mainly as a result of the DIS acquisition, gross margin improved by 40 bps to 17.7% compared to the same quarter last year. Favourable changes in estimates for French payroll provisions had a 20 bps positive impact on the quarter’s gross margin in 2006 and 2005.

Selling, General and Administrative Expenses (SG&A)

SG&A were up 10% for the full year. SG&A as a percentage of revenues for the full year decreased 20 bps to 13.3% and by 40 bps organically. In the fourth quarter SG&A increased 4%, which represents, as a percentage of revenues, a drop of 50 bps to 13.4% versus the same quarter last year. Additional corporate expenses increased the fourth quarter’s 2006 SG&A as a percentage of revenues by 20 bps compared to Q3 2006. On an organic basis SG&A grew 3%, the office network 5% (+310 offices) and FTEs 2% (+550 FTEs) compared to the same quarter last year. At the end of 2006, Adecco had over 35,000 FTEs and over 6,700 offices.

Operating Income

Operating income for the fiscal year 2006 was EUR 816 million, an increase of 33% (27% organically) compared to 2005. Operating income margin improved to 4.0% versus 3.4% last year. In the fourth quarter Adecco’s operating income grew 36% (32% organically) to EUR 222 million, which corresponds to an operating margin improvement of 90 bps to 4.2%.

Interest Expense and Other Income / (Expenses), net

Interest expense was EUR 51 million in 2006 and EUR 13 million in the fourth quarter (2005: EUR 52 million; Q4 2005: EUR 12 million). Interest expenses are expected to be approximately EUR 56 million for the full year 2007. Other income / (expenses), net were EUR 20 million in 2006 and EUR 8 million for the period from October to December. This is EUR 37 million less compared to the same quarter last year, in which Adecco realized a EUR 42 million gain on the divestment of a minority holding in PSI (Professional Service Industries).

Provision for Income Taxes

The effective tax rate for the fiscal year 2006 was 21% compared with 25% in the prior year. The fourth quarter of 2006 was positively impacted by a tax benefit related to the release of a valuation allowance on deferred tax assets in the US. Excluding the effect of this release the underlying tax rate for 2006 was approximately 29%. For the full year 2007, Adecco expects an effective tax rate of around 29%.

Net Income and EPS

Net income was up 35% to EUR 611 million in 2006 (2005: EUR 453 million). Basic EPS was EUR 3.28 for 2006 (EUR 2.43 for 2005). In the fourth quarter, Adecco reported a net income of EUR 212 million, representing a net income margin of 4.0%. The release of the tax valuation allowance in the US positively impacted full year and fourth quarter 2006 basic EPS by EUR 0.34.

Balance Sheet, Cash-flow, and Net Debt¹

The Group generated EUR 747 million of operating cash flow in 2006, compared with EUR 298 million in 2005. The main reasons for this increase are a higher net income as well as the timing of cash payments due to an additional trading week in 2004, which negatively impacted the operating cash flow in 2005. Net debt increased by EUR 132 million to EUR 556 million at the end of December 2006 compared to the year end of 2005. This increase was mainly due to the purchase of DIS AG (EUR 552 million net of cash acquired) and treasury shares (EUR 123 million), capital expenditures (EUR 83 million) as well as the payment of dividends (EUR 120 million), partially compensated by the operating cash flow. In 2006 DSO improved 1 day to 59 days compared to 2005. Return on capital employed (ROCE) reached 20.3% versus 18.5% in 2005.

Currency Impact

Currency fluctuations had a minimal impact on the fiscal year 2006 revenues and operating income, while there was a 3% negative impact in the fourth quarter mainly due to the weakness of the US dollar and the Japanese yen.

Dividend payout

The Board of Directors will propose a dividend of CHF 1.20 per share for 2006 (2005: CHF 1.00) for approval by shareholders at the Annual General Meeting. The proposal implies a dividend payout ratio on net income of 25%, when excluding the release of a valuation allowance on deferred tax assets in the US. It is planned that the dividend for the shares will be paid on May 22, 2007, the dividend for the ADRs will be paid on June 25, 2007.

GEOGRAPHICAL PERFORMANCE

In France Adecco posted revenue growth of 8% to EUR 6.8 billion in 2006 and 7% in the fourth quarter. Gross margin increased by 10 bps compared to 2005. The 2005 acquisition of Altedia as well as higher permanent placement revenues more than compensated for the gross margin decline in the temporary business. In the fourth quarter gross margin declined 10 bps compared to Q4 2005 when excluding the impact of provision releases. Disciplined cost management led to an operating income increase by 8% in 2006 and 20% in the fourth quarter.

In the USA & Canada Adecco increased revenues in constant currency by 1% to EUR 3.7 billion in 2006. Strong demand for permanent placement and an improved customer and skill mix in the temporary business resulted in 110 bps higher gross margin and an operating margin improvement to 4.2% (2005: 3.8%). In the fourth quarter revenues declined by 4% in constant currency and 3% adjusted for trading days. Adecco remained price disciplined in a softening market environment. Due to favourable workers compensation cost development in the fourth quarter of 2006 and 2005 operating margin remained stable at 5.2%.

In 2006 UK & Ireland added 19% in revenues in constant currency mainly driven by good demand in the IT business line. In the fourth quarter the revenue addition in constant currency was 13%. Changes in business and customer mix had a negative impact on gross margin, which were not fully compensated by efficiency improvements. As a result operating income grew 11% in 2006 and 2% in constant currency in the fourth quarter compared to last year.

In Japan revenues in constant currency grew 8% in 2006 and 7% in the fourth quarter, while operating margin expanded to 5.9% and 5.6% (2005: 4.6%; Q4 2005: 4.6%). The general shortage of candidates, combined with the continued solid economic environment and good permanent placement revenues led to better gross margins in the full year as well as the fourth quarter.

1 Net debt is a non-US GAAP measure and comprises short-term and long-term debt less cash and cash equivalents and short-term investments.

Adecco SA – FY and Q4 2006 Results Page 3 of 11 02/03/2007

In Germany and the Nordics Adecco added 111% and 45% respectively in constant currency (30% and 39% organically) to revenues in 2006. In the fourth quarter revenue addition was 114% and 49% in constant currency (20% and 41% organically). Changes in regional legislation and higher acceptance levels of temporary staffing combined with a favourable economic environment continue to be the main drivers behind this organic growth. Italy, Iberia and Benelux grew revenues by 10%, 23% and 12% respectively in 2006 (Iberia organically 10%) and 8%, 13% and 7% in the fourth quarter. In Iberia the fourth quarter had 3% less trading days, in Italy and Germany 2%, compared to 2005.

Adecco SA – FY and Q4 2006 Results Page 4 of 11 02/03/2007

In 2006 Adecco’s Human Capital Solutions (HCS) business grew revenues by 12% in constant currency and declined 4% when excluding the impact of acquisitions and currency.

MANAGEMENT OUTLOOK

Current trading conditions combined with the key indicators for the global staffing services market continue to point to a favourable growth for the industry. The Group therefore remains committed to its objective of revenue growth of at least 7-9% per annum on average for the coming years providing no material changes to the macroeconomic environment. At the same time management continues to be confident that the focus on value based management and professional and specialized business fields will allow Adecco to continuously improve 2009 operating income margin to over 5% and return on capital employed (ROCE) to above 25%.

In January 2007 revenues continued to grow 8% when excluding the impact of trading days, currency and acquisitions.
