Short-Term Borrowings and Long-Term Debt
Short-Term Borrowings and Long-Term Debt	Note 5. Short-Term Borrowings and Long-Term Debt In August 2011, the Company entered into a loan and security agreement (the “2011 Loan Agreement”) with Silicon Valley Bank (SVB), in order to finance certain capital expenditures anticipated to be made by the Company in connection with its move in March 2012 to new office and laboratory space in Cranbury, New Jersey. The 2011 Loan Agreement provides for up to $3 million of equipment financing through January 2014. Borrowings under the 2011 Loan Agreement are collateralized by equipment purchased with the proceeds of the loan and bear interest at a variable rate of SVB prime + 2.5%. The current SVB prime rate is 4.0%. In February 2012, the Company borrowed approximately $1.0 million from the 2011 Loan Agreement which will be repaid over the following 2.5 years. The 2011 Loan Agreement contains customary terms and conditions, including a financial covenant whereby the Company must maintain a minimum amount of liquidity measured at the end of each month where unrestricted cash, cash equivalents, and marketable securities, are greater than $20 million plus outstanding debt due to SVB. The Company has at all times been in compliance with these covenants during the term of the agreement. At March 31, 2013, the total amount due under the 2011 Loan Agreement was $0.6 million. The carrying amount of the Company’s borrowings approximates fair value at March 31, 2013.
