[1] In March 2014, the Company entered into an equipment sale leaseback agreement with a financing company. The cash proceeds from the transaction were $0.9 million. The Company leased the equipment for a period of 36 months at an effective interest rate of approximately 6% and has the option to purchase the equipment at a nominal amount at the end of the lease term. The Company has accounted for this transaction as a financing arrangement, wherein the equipment remains on the Company’s books and will continue to be depreciated.
