Investment in Variable Interest Entity	Investment in Variable Interest Entity In 2012, the Company provided a strategic partner (the “Borrower”) in the life science industry a loan of $3.0 million to support their future product development and other working capital requirements. The loan bears interest at a rate of 9%. The outstanding principal and interest under the loan is payable in May 2015. The Company also received warrants to purchase the Borrower's common stock in the event of an equity offering by the Borrower. The Company determined that the loan and the warrants had fair values of $2.8 million and $0.2 million, respectively, as of September 30, 2012. At September 30, 2013, the loan and warrants had carrying values of $2.9 million and $0.2 million, respectively. The loan and the warrants are recorded as long-term other assets in the Consolidated Balance Sheets. The loan agreement also provides the Company with certain other rights related to conversion of the loan, first refusal to acquire the Borrower and a redemption premium. The loan is secured by a security agreement that gives the Company the first interest in all of the assets of the Borrower. The Company determined that the level of equity investment at risk is not sufficient for the entity to finance its activities without additional financial support and as a result, represents a variable interest entity. However, the Company does not have the power to direct the activities that most significantly impact the Borrower's economic performance and would not absorb the majority of the expected losses from the Borrower, and therefore does not qualify as the primary beneficiary. The Company has no future contractual funding commitments to the Borrower and as a result, the Company's exposure to loss is limited to the outstanding principal and interest under the loan.
