Total revenue for the quarter ended ended December 31, 2012 (the third quarter of fiscal 2013) increased 6% to $6,525,221 compared to $6,158,526 for the quarter ended December 31, 2011 (the third quarter of fiscal 2012). The increase was due to a 7% increase in product sales.

Gross profit margin increased to 73% of revenue for the third quarter of fiscal 2013 compared to 65% for the third quarter of fiscal 2012, due to a more favorable revenue mix and more efficient product manufacturing.

Total expenses decreased 13% for the third quarter of fiscal 2013 compared to the third quarter of fiscal 2012 due to a 30% decrease in research and development expense, partially offset by a 10% increase in selling, general, and administrative expense. The decrease in research and development expense was due to the completion of certain research and development projects, and may not be representative of future trends. Research and development expense can fluctuate significantly depending on staffing, project requirements, and contract research and development activities. The increase in selling, general, and administrative expense was primarily due to increases in sales commissions and legal expenses.

The provision for income taxes was $1,415,590 for the third quarter of fiscal 2013 compared to $1,047,519 for the third quarter of fiscal 2012. The effective tax rate was 33% of income before taxes for the third quarter of fiscal 2013 compared to 31% for the third quarter of fiscal 2012. The increase in effective tax rate was due to a higher Federal effective tax rate. Our effective tax rates can fluctuate due to a number of factors, including Federal and state tax rates and regulations, the mix between taxable and tax-exempt securities in our marketable securities, and other factors, some of which are outside our control.

The 27% increase in net income in the third quarter of fiscal 2013 compared to the prior-year quarter was primarily due to increased product sales and increased gross profit margin.

Total revenue for the nine months ended December 31, 2012 decreased 6% to $19,810,922 compared to $20,970,921 for the nine months ended December 31, 2011, due to a 40% decrease in contract research and development revenue.

The decrease in research and development revenue was due to the completion of certain contracts and contract activities. Contract research and development activities can fluctuate for a number of reasons, some of which are beyond our control, and there can be no assurance of additional or follow-on contracts for expired or completed contracts.

Gross profit margin increased to 74% of revenue for the first nine months of fiscal 2013 compared to 66% for the first nine months of fiscal 2012, due to a more favorable revenue mix, a more favorable product sales mix, and more efficient product manufacturing.

Total expenses decreased 1% for the first nine months of fiscal 2013 compared to the first nine months of fiscal 2012 due to a 2% decrease in research and development expense and a 1% decrease in selling, general, and administrative expense. The expense decreases may not be representative of future periods. Research and development expense can fluctuate significantly depending on staffing, project requirements, and contract research and development activities. Selling, general, and administrative expense can fluctuate significantly depending on a number of factors including legal expenses.

The provision for income taxes was $4,211,964 for the first nine months of fiscal 2013 compared to $3,825,819 for the first nine months of fiscal 2012. The effective tax rate was 33% of income before taxes for the first nine months of fiscal 2013 compared to 32% for the first nine months of fiscal 2012. Our effective tax rates can fluctuate due to a number of factors, including Federal and state tax rates and regulations, the mix between taxable and tax-exempt securities in our marketable securities, and other factors, some of which are outside our control.

The 5% increase in net income in the first nine months of fiscal 2013 compared to the prior-year period was primarily due to increased gross profit margin, partially offset by decreased contract research and development revenue.

Liquidity and capital resources
At December 31, 2012 we had $81,228,528 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 nine months of fiscal 2013 was primarily due to $8,422,080 in net cash provided by operating activities and a $800,305 net increase in the market value of our marketable securities, partially offset by purchases of fixed assets of $1,607,130. Fixed asset purchases were 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.
