Acquisitions [Abstract]
Acquisition of LifeGen	22. Other income (expense), net Other income (expense), net was $7.0 million of expense in 2011, $4.4 million of income in 2012 and $2.8 million of income in 2013. The Company recorded foreign currency transaction losses with respect to its intercompany receivables and payables with certain of its international affiliates, including markets that are newly opened or have remained in a loss position since inception. Generally, foreign currency transaction losses with these affiliates would be offset by gains related to the foreign currency transactions of the Company's yen-based bank debt. Other income (expense), net also includes approximately $4.8 million, $5.2 million and $3.0 million in interest expense during 2011, 2012 and 2013, respectively. The Company cannot estimate the degree to which its operations will be impacted in the future, but it remains subject to these currency risks. However, the majority of these transaction losses are non-cash, non-operating losses. 23. Acquisitions In the fourth quarter of 2012, a subsidiary of the Company acquired NOX Technologies, Inc. ("NOX"), a biotechnology and biodiagnostic company based in Malvern, Pennsylvania, for approximately $12.6 million in cash. The NOX acquisition included patents and previously licensed technology utilized in connection with the Company's research efforts and incorporated into some of the Company's products. As the acquisition was deemed to be an asset acquisition, the Company has allocated the purchase price to the patents and will amortize the patents over their remaining lives, which were approximately 8 years. In the fourth quarter of 2011, a subsidiary of the Company acquired substantially all of the assets of LifeGen Technologies, LLC ("LifeGen"), a genomics company based in Madison, Wisconsin for approximately $11.7 million in cash. The LifeGen acquisition included LifeGen's proprietary tissue bank and gene expression database, patents and other intellectual property related to anti-aging gene research. The Company has allocated the purchase price primarily to the patents and will amortize the patents over their remaining lives, which were approximately 17 years. TABLE OF CONTENTS
