Aggregate Accounts Receivable, Net of Allowance for Doubtful Accounts

Some of the Company’s customers, particularly in Europe, have extended or delayed payments for products and services already provided. Collectability concerns regarding the Company’s accounts receivable from these customers, for the most part in Greece, Italy, Spain and Portugal resulted in an increase in the allowance for doubtful accounts related to these countries. If the financial condition of these customers or the healthcare systems in these countries deteriorate such that the ability of an increasing number of customers to make payments is uncertain, additional allowances may be required in future periods. The aggregate net current and long-term accounts receivables for Spain, Italy, Greece and Portugal and the percentage of the Company’s total net current and long-term accounts receivables represented by the net current and long-term accounts receivables in those countries at December 31, 2013 and 2012 are as follows:

	December 31, 2013			December 31, 2012
