Thank you, Schond, and good afternoon. It's a pleasure to lead this call for the first time as a member of the Halozyme team. My early observations in my first weeks at Halozyme, during which I have conducted multiple program reviews, have confirmed for me the unique potential value proposition that Halozyme presents and the opportunity that exists to build a multiproduct company with strong business fundamentals and attractive returns for shareholders. 2013 was a year of significant progress at Halozyme with a full-year 2013 revenue growth to $54.8 million and net loss of $83.5 million, reflecting our increased product sales and our investment to advance and unlock the value of our proprietary programs. Let me begin by reviewing progress in our proprietary programs. The program I am most excited about is PEGPH20. We are evaluating this agent in pancreatic cancer for 2 important reasons: The first is a significant unmet medical need that exists for a better treatment for pancreatic cancer. Despite recent advances for the approximately 100,000 patients in the U.S. and Europe who are diagnosed each year, frequently with advanced disease, the 5-year survival rate for this devastating disease is still very low. The second reason is that PEGPH20 has been shown to deplete hyaluronan, or HA, high levels of which are present in the majority of pancreatic ductal adenocarcinoma and is associated with poor prognosis. The high hyaluronan levels create an environment that supports tumor growth and blocks access of therapy to the tumor. We have demonstrated that PEGPH20 works by depleting the hyaluronan, which in turn allows for increased access or delivery to the tumor of systemic anticancer treatments. During 2013, we presented results from our PEGPH20 clinical development program. Data presented at the American Society of Clinical Oncology meeting this past June showed that PEGPH20, in combination with gemcitabine in patients with histologically confirmed stage 4 metastatic pancreatic cancer, demonstrated a 42% overall response rate for the 24 patients treated at therapeutic dose levels. Gemcitabine alone has historically demonstrated an overall response rate in the 5% to 10% range. Further supporting the proposed mechanism of action, we find that in subjects with tumors with high levels of HA the overall response rate was 64%. Additional data from this study was presented at the European Society for Medical Oncology in September 2013, where in an exploratory analysis, progression-free survival and overall survival were longer in patients with high HA levels when compared to patients with low HA levels or the overall intent-to-treat population. In April of 2013, we initiated our first Phase II study in multicenter trial in previously untreated stage 4 pancreatic ductal adenocarcinoma patients who will be randomized to receive nab-paclitaxel or Abraxane and gemcitabine with or without PEGPH20. The primary outcome measure will be progression-free survival. Secondary endpoints include progression-free survival by HA level and overall survival. Patient recruitment is proceeding as planned and we expect to be fully enrolled in the second half of 2014. In October of 2013, SWOG funded and initiated a Phase 1b/2 randomized clinical trial, testing a modified FOLFIRINOX regimen with and without PEGPH20, and a planned 144 stage 4 pancreatic cancer patient study. The primary endpoint of this study is overall survival. Secondary endpoints include progression-free survival, objective tumor response, as well as the frequency and severity of adverse events and overall tolerability. The first patient was enrolled in this trial in January of 2014. Based on this encouraging preclinical and early clinical results we have observed with PEGPH20 so far, we are planning to evaluate PEGPH20 and at least one additional tumor type in a study planned to start in the fourth quarter of 2014. Work is underway to finalize the selection of the tumor type and trial design. Turning now to Hylenex. Hylenex is indicated for the increased dispersion and absorption of other drugs. Our goal is to expand the indications for Hylenex and we have identified Hylenex pre-treatment in patients with type 1 diabetes using insulin pumps as an area where we may create and capture additional value, as these patients can face challenges maintaining good glycemic control as a result of the timing of onset and duration of action of their insulin. In the first quarter of 2013, we initiated CONSISTENT 1, our large late-stage clinical study designed to evaluate the effect of Hylenex pre-administration in conjunction with rapid-acting analog insulins in patients with type 1 diabetes on insulin pump therapy. CONSISTENT 1 has completed enrollment of over 440 adult patients with type 1 diabetes. The primary endpoint is non-inferiority of A1C between the patient group pretreated with Hylenex prior to receiving their analog insulin and the patient group receiving analog insulin alone. We recently changed the time point for assessment of the primary endpoint from 4 months to 6 months based on feedback we received from the FDA this quarter. Secondary endpoints for the study include comparison of hypoglycemia and hyperglycemia rates, as well as safety outcomes. We plan to communicate top line results from the CONSISTENT 1 study in the first quarter of 2014. Additionally, we are currently in dialogue with the FDA regarding the path for a labeling update to include key safety and efficacy data prior to initiation of any promotion of Hylenex in this use. Our dialogue with the FDA is ongoing and when we have more definitive information to share, we will discuss this information at an appropriate time. Turning now to our third proprietary program, HTI-501. We're exploring HTI-501, a conditionally active recombinant human protease that targets collagen as a potential treatment for cellulite. We recently completed a Phase I/II proof of concept clinical trial outside the United States in 36 healthy adult females with cellulite and expect to report top line data at the 28-day, 3-month and 6-month end points in the first quarter of 2014. Previously reported interim data for 12 patients at the 28-day observation point, all physician assessment of cellulite has been encouraging. This study was designed to provide proof of concept. We will need additional chemistry, manufacturing and controls work prior to being able to file an IND in the U.S. We're undertaking a review of the strategic alternatives to advance this program, including partnering with the goal of defining a path that maximizes shareholder value. Now moving to our partnered programs, our most advanced partnered program is with Roche and its Herceptin SC. Herceptin SC received European Commission approval in August of 2013 for the treatment of HER2-positive breast cancer. Herceptin SC is a simple fixed-dose subcutaneous formulation that reduces dosing time to 2 to 5 minutes, compared to the 30 to 90 minutes required for IV. Herceptin SC use may allow patients to benefit by spending less time in the hospital and could also reduce time spent by physicians and other health care providers in treatment administration. Roche indicated its plan of parity of pricing to the IV formulation at launch and has now launched in multiple European markets, including Germany and the United Kingdom. In recent public comments, Roche have commented that the launch is progressing well. In January of 2014, the European Committee for Medicinal Products for Human Use, or CHMP, recommended that European Commission approve Roche's subcutaneous formulation of MabThera, which uses Halozyme's rHuPH20 for the treatment of patients with common forms of non-Hodgkin's lymphoma or NHL. Currently, MabThera is delivered by an intervenous infusion, which takes approximately 2.5 hours. The new MabThera's SC formulation comes as a ready-to-use fixed-dose 1,400-milligram solution, which shortens pharmacy preparation time and potentially will reduce the overall impact on hospital resources. Roche expects a final decision from the European Commission in the coming months. Moving over to our development program with Baxter. HyQvia is a combination of immunoglobulin 10% and Halozyme's rHuPH20 to facilitate the absorption and dispersion of the immunoglobulin subcutaneously. Following EMA approval in May of 2013, Baxter launched HyQvia in the first European country in July of 2013. Pricing discussions and subsequent launches in additional markets are continuing. Recall that Baxter filed a new marketing authorization and is seeking a price premium, and we expect it will take time to establish HyQvia pricing on a country-by-country basis. In the December of 2013, Baxter completed submission of an amended Biologics License Application, or BLA, to the FDA to reinitiate the review process for approval of HyQvia in the U.S. In 2012, in its complete response letter, the FDA requested additional preclinical data for the filing. Baxter and Halozyme worked together to generate the data, and we believe we have addressed the FDA questions. A 6-month review period is expected. In summary, our plans are to grow shareholder value by gaining approval and launching our own proprietary products, maximizing the royalty revenue from our existing collaborations and expanding and deepening our collaborations using our ENHANZE Technology. We look forward to updating you on our progress throughout the year. With that, I'll now turn the call over to David Ramsay, who can provide more detail on our financial results released this afternoon. David?
