Table of ContentsLiquidity and capital resources At September 30, 2012 we had $79,861,859 in cash plus short-term and long-term marketable securities compared to $73,541,463 at March 31, 2012. Our entire portfolio of short-term and long-term marketable securities is classified as available for sale. The increase in cash plus marketable securities in the first six months of fiscal 2013 was primarily due to $6,432,261 in net cash provided by operating activities and a $835,601 net increase in the market value of our marketable securities, partially offset by purchases of fixed assets of $1,019,269, primarily for production equipment and leasehold improvements. We currently believe our working capital and cash generated from operations will be adequate for our needs at least for the next 12 months. 13
