[1] On September 10, 2012, we entered into a revolving credit agreement ("Euro Credit Agreement") to support the operations of our Central Europe segment. The Euro Credit Agreement provides for a 1-year revolving credit facility of €150 million on an uncommitted basis. On April 3, 2012, we entered into a revolving credit agreement (the ''Credit Agreement''). The Credit Agreement provides for a 4-year revolving credit facility of $300 million that was subsequently amended to increase the borrowing limit to $550 million. The Credit Agreement contains customary events of default and specified representations and warranties and covenants, including, among other things, covenants that limit our subsidiaries' ability to incur certain additional priority indebtedness, create or permit liens on assets, or engage in mergers or consolidations. In the second quarter of 2011, we entered into an agreement for a 4-year revolving multicurrency credit facility of $400 million, which provides a $100 million sub-facility available for the issuance of letters of credit.In relation to the credit facilities issued during 2012, we incurred $5.5 million of total issuance costs and up-front fees, which are being amortized over the terms of each respective facility. There were no outstanding borrowings on these credit facilities as of December 29, 2012.
