Adecco shareholders approve dividend of CHF 2.00 per share

April 15, 2014 CORPORATE

The shareholders attending the AGM, which took place in Lausanne today, confirmed the following members of Adecco’s Board of Directors for a further term of one year: Rolf Dörig (Chairman), Dominique-Jean Chertier, Alexander Gut, Andreas Jacobs, Didier Lamouche, Thomas O’Neill, David Prince and Wanda Rapaczynski.

Shareholders voted in favour of the Board of Directors’ proposal to pay a cash dividend of CHF 2.00 per share for the financial year 2013; an 11% increase compared to the prior year. The total amount of the dividend distribution for 2013 will be paid out of free reserves after reallocation from the capital contribution reserve, and is therefore exempt from Swiss withholding tax. The dividend payment to shareholders will take place on April 29, 2014.

Furthermore, shareholders approved amendments to the Articles of Incorporation. These are mainly related to the implementation of the Ordinance against Excessive Remuneration in listed Stock Corporations, which resulted from the Minder Initiative. Pursuant to the new Articles of Incorporation shareholders will vote prospectively on the maximum total amount of remuneration for the Board of Directors and for the Group Executive Committee as of the AGM 2015. The Remuneration Report, which includes details of the current remuneration paid, will continue to be submitted to shareholders for an advisory vote.
