Financial Instruments and Their Fair Values

Financial instruments consist mainly of cash and cash equivalents, accounts receivable, accounts payable, bank loans, overdraft facilities, Convertible Senior Notes and Secured Senior Notes. The monetary assets represented by these financial instruments are primarily located in Poland, Hungary and Russia. Consequently, they are subject to currency translation risk when reporting in U.S. Dollars.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

 

   

Cash and cash equivalents, accounts receivable, accounts payable and overdraft facilities—the carrying amount approximates fair value because of the short maturity of those instruments.

 

   

Convertible Senior Notes and Secured Senior Notes — the market value of these bonds as of December 31, 2011 amounts to $248.0 million and $702.7 million, respectively.
