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.
