Prepaid expenses increased by an aggregate of $1,500,000 in the quarter ended March 31, 2011 due to amounts paid pursuant to the Company's obligations under a sales contract and an extended warranty and maintenance agreement to provide repair and maintenance services over an eight year period for products sold under a contract with a foreign government. This amount is being amortized on a straight-line basis at an annual rate of $187,500 over the contract period, and is being recognized as a component of cost of sales. As of September 30, 2011, $187,500 of the total prepayment was classified as a current asset and $1,218,750 was classified as noncurrent.
