In case of a .EU Domain Name Transfer, the Expiry date is updated to 1 year from the date of Transfer and not to 1 year from the date the domain name was set to expire prior to Transfer.
For example, if a Domain Name has the Expiry date as 24 Oct, 2007 and it gets Transferred to another Registrar on 2 Sep, 2007. The new Expiry date will be 2 Sep, 2008 and not 24 Oct, 2008.
