Thank you, Jon, and good morning, everyone. I'm pleased to share with you some details regarding our third quarter 2012 financial results. Throughout 2012, we have consistently achieved the financial goals established for the company in the third quarter as further evidence of our accomplishments. We continue to deliver substantially reduced general and administrative expenses in 2012, which are roughly half of 2011 levels. These reductions continue to illustrate our commitment to a key operating principle, which is focusing our cash resources on advancing our development programs while minimizing noncritical and non-project spending. In addition, we are narrowing our development focus and related expenditures to antivirals and hereditary angioedema. Now I'd like to discuss our third quarter financial results for 2012, which are summarized on Slide 3. Revenues for the third quarter of 2012 were $5.8 million compared to $5.2 million in the third quarter of 2011. This revenue increase resulted primarily from the recognition of $2.8 million of deferred RAPIACTA royalty revenue from Shionogi, which was largely offset by a decrease in collaboration revenue from HHS/BARDA. Our revenue situation in the third quarter of 2012 is unique as we recognized 7 quarters of deferred RAPIACTA royalty revenue. This recognition occurred in the third quarter of 2012 as we needed 2 complete and representative flu seasons in Japan to give us reasonable historical experience to record an appropriate amount of RAPIACTA royalty revenue in accordance with Generally Accepted Accounting Principles. As mentioned in the press release, there is no underlying impact to our cash balance as all royalty payments were directed to pay all obligations on our nonrecourse notes payable. Continuing the revenue discussion, the increase in royalty revenue was substantially offset by a decrease in the amount of revenue associated with reimbursement of peramivir development. Peramivir development activity and related reimbursement under the HHS/BARDA contract is below levels in 2011 as 2012 peramivir development activity was predominantly focused on the 301 clinical trial for which there was slower enrollment due to mild flu seasons, whereas in 2011 there was more substantial and broader peramivir development activity. Third quarter 2012 R&D expenses were $12.1 million, down from $15.1 million in last year's quarter. Our R&D program expense mix has changed as lower development costs associated with the ulodesine and peramivir programs was partially offset by higher development costs associated with the BCX5191 and 4161 preclinical programs. We expect our R&D concentration to continue toward our preclinical programs, especially on our BCX4161 drug candidate for hereditary angioedema, as we expected to begin Phase I testing before year end. In addition, the R&D mix will be further impacted by the recent suspension of patient enrollment in our peramivir 301 study and completion of the ulodesine Phase II development program. Third quarter 2012 general and administrative expenses were $1.6 million and reflect a 46% reduction from the $3 million of expense incurred in the third quarter of 2011. This decrease in administrative expenses is even more impressive as 2012 expenses included a portion of Presidio due diligence and merger costs, which when excluded, provide for an over 53% decrease in 2012 administrative expenses. As mentioned earlier, we are extremely pleased with our ability to curtail administrative costs and more fully dedicate resources towards advancing our drug candidate portfolio. Moving down below the operating line. We incurred $1.2 million of non-cash interest expense and mark to market losses of approximately $600,000 in the third quarter of both 2012 and 2011. The interest expense and hedge loss for both periods relates to our nonrecourse debt and our hedge arrangement enacted in conjunction with the RAPIACTA royalty monetization completed in the first quarter of 2011. Our 9-month financial results for 2012 and 2011 are summarized on Slide 4. Revenue for the 9 months ending September 30, 2012, increased to $22.2 million compared to $14.1 million for the 9 months ending September 30, 2011. The increase was primarily due to the recognition of approximately $8 million of previously deferred forodesine-related revenue during the first quarter of 2012, and $2.8 million of RAPIACTA revenue recognized during the third quarter. Revenue from reimbursement on peramivir development for the 9 months of 2012 decreased $1.7 million or 14% compared to the same period of 2011. 9-month 2012 R&D expenses were $40.4 million, down slightly from $43 million in the first 9 months of 2011. Lower ulodesine and peramivir development costs were partially offset by higher development costs in 2012 associated with the BCX5191 and 4161 preclinical programs, and recognition of $1.9 million of previously deferred forodesine expenses associated with the amendment of our Mundipharma agreement. General and administrative costs through September 30, 2012 decreased sharply to $4.9 million from $9.9 million in the 9-month period of 2011. The 51% decrease resulted from a significant reduction of noncritical consulting and other administrative expenses, as well as onetime expenses incurred in the 2011 relocation of our corporate headquarters. In the first 9 months of 2012, we incurred $3.5 million of interest expense compared to $2.6 million in 2011. The difference resulted from 9 months of interest in 2012 versus approximately 7.5 months in 2011. The 2012 period also included the mark to market loss of $1.5 million compared to $2.9 million for the same period of 2011, reflecting changes in the U.S. dollar Japanese yen exchange rate. Now moving to Slide 5. I'd like to discuss our cash usage and our 2012 financial outlook. At September 30, 2012, we had cash and investments of $43.8 million compared to $57.7 million at the end of 2011. Our operating cash usage for the third quarter and 9 months ended September 30, 2012, was $9.7 million and $29.7 million, respectively. As a reminder, operating cash used excludes any impact of our royalty monetization, hedge collateral posted or returned, sales stock in the marketplace and any other nonroutine cash inflows. Considering recent events in our peramivir and BCX5191 programs, we are evaluating operational changes to decrease our cost structure to better position our company to achieve value-creating milestones and to conserve our cash resources to extend further into the future. In regards to our outlook for the remainder of 2012, we are reiterating our prior operating cash utilization guidance of $37 million to $43 million and operating expense guidance of $57 million to $69 million as we announced in August. As a reminder, our outlook depends on peramivir-related operating expenses and excludes any consideration of cash inflows derived from our licensing ulodesine. That concludes my financial review and I'd like to turn the call over to Dr. Bill Sheridan. Bill?
