As of December 31, 2011, the Company has $2,500,000 in deposits toward the purchase of three MEVION S250 proton beam radiation therapy (“PBRT”) systems from Mevion Medical Systems, Inc., a development-stage company. For the first two machines, the Company has a commitment to total deposits of $3,000,000 per machine until FDA approval is received, at which time the remaining balance is committed. The delivery dates for the first two machines are now anticipated to be in 2013 and 2014. For the third machine, the Company has a commitment to total deposits of $500,000 until FDA approval is received, at which time the remaining balance is committed. The Company has entered into a partnership agreement with a radiation oncology physician group, which has contributed $100,000 towards the deposits on the third machine. The Mevion PBRT system is not commercially proven and there is no assurance FDA approval will be received. The Company reviews the carrying value of these deposits for impairment on a quarterly basis, or as events or circumstances might indicate that the carrying value may not be recoverable. See Note 12-Commitments and Contingencies for additional discussion on purchase commitments.
