Adecco Group successfully lengthens its debt maturity profile

Zurich, Switzerland, April 7, 2011: Adecco Group, the worldwide leader in Human Resource services, announces today the final results and pricing of the tender and exchange offers, as well as the conditions for the new 7-year fixed rate notes. The final acceptance amount for the tender and exchange offers for the EUR 500 million 4.5% notes due 2013 and the EUR 500 million 7.625% notes due 2014 will be EUR 293 million. The nominal amount of the new 7-year fixed rate notes due 2018 is EUR 500 million with a coupon of 4.75%. The purpose of the transaction is to lengthen Adecco Group’s debt maturity profile and to take advantage of favourable market conditions.

Subsequent to the announcement dated March 31, 2011, the Adecco Group completed the pricing in respect of its exchange and tender offers, as well as for the new 7-year fixed rate notes, expected to be issued on the Settlement Date, April 14, 2011. Upon issuance by Adecco International Financial Services B.V. (the Issuer), and guarantee by Adecco S.A., of the new EUR 500 million 4.75% fixed rate notes due 2018, Adecco Group will have successfully refinanced an aggregate amount of EUR 293 million of outstanding notes, consisting of EUR 165 million of its EUR 500 million 4.5% notes due 2013 and EUR 128 million of its EUR 500 million 7.625% notes due 2014.

Based on the new debt maturity profile, Adecco updates its 2011 interest expense guidance and expects interest expense to amount to approximately EUR 70 million for the full year, mainly reflecting the slight increase in interest-bearing debt. In its Q2 2011 results, Adecco will recognize a one-time expense of approximately EUR 10million in connection with the exchange and tender offers.
