Thanks, Alastair. We will now take a look at what lies ahead. As we have said, in addition to our market products, we develop and maintain a promising pipeline and are working diligently to move these products forward to approval in commercial launch. Leveraging our commercial strength and all the know-how from growing the products already in our portfolio, we are confident in our prospect. I'd like to include a few additional updates regarding our pipeline. Let's start with our hydrocodone polistirex and chlorpheniramine polistirex extended release suspension, which is a generic equivalent of Tussionex used for the relief of cough and upper respiratory symptoms associated with allergy or a cold in adults and children 6 years of age and older. We are pleased with the significant progress of the manufacturing efforts in the most recent quarter and continue to look forward to entering the market for the upcoming 2013 cough and cold season. Moving to BETHKIS, which is a Tobramycin Inhalation Solution and is indicated for the management of cystic fibrosis patients with Pseudomonas aeruginosa. This is a very common condition in patients with CF, and nebulized tobramycin is considered the gold standard in treatment. This product is progressing as previously stated and remains on track to launch in Q3. Looking at RETAVASE, the quality of developmental efforts continue toward qualifying a new raw material supplier and transfer of certain aspects of the manufacturing process. We are making good progress on the FDA request from December 2012 and pending the outcome of certain investigational and schedule activities plan to initiate manufacture of new developmental batches this year. We remain positive on our ability to resolve the open issues. Expect to hear more detailed information from us on future calls, and we still anticipate the relaunch of RETAVASE in 2015. In parallel, using the current API RETAVASE, we plan to develop experimental batches and move forward our discussions with the FDA in regards to our catheter clearance program. We believe we can leverage key learnings from the current development program on RETAVASE to increase our probability of a success with catheter clearance. In regards to LIXAR, we continue to evaluate the viability of this investigational product candidate. Following the FDA's issuance of a complete response letter and request for additional clinical studies, we have committed to have a meeting with the FDA to discuss the path forward. The planning and statistical evaluation needed to support this meeting request is nearing completion. There remains our goal to request this meeting with the FDA very soon. As you can see by the financial and operational progress we've made in the first quarter of 2013, we feel more confident than ever that we have the right strategy in place to ensure that Cornerstone is well positioned for future growth. This morning, we announced the product deal with Digestive Care, Inc. to acquire exclusive U.S. rights to market the product PERTZYE for cystic fibrosis patients. We are excited about the addition of PERTZYE. It is a market-ready treatment for a difficult and common condition faced by an estimated 90% of cystic fibrosis patients called exocrine pancreatic insufficiency or EPI. For patients with EPI, food is not properly digested in their intestines, causing malabsorption and nutrient deficiency. PERTZYE is administered in a delayed-release capsules containing a mixture of the digestive enzymes amylase, lipase and protease, which are necessary for food digestion in patients with EPI. PERTZYE is the only FDA-approved pancreatic enzyme replacement therapy or PERT, containing bicarbonate-buffered enteric coated microspheres designed to optimize the pH environment for enzyme activity and nutrient absorption. We believe this is a strong differentiator for this product. We also believe that PERTZYE will have an immediate positive impact on our net sales. Additionally, with net sales of all PERT products reaching approximately $200 million in the CF category, we see significant opportunity for growth. It is also worth noting that PERTZYE is protected by exclusivity rights from the said FDA approval until 2017, along with other patent and certain know-how that will make this product extremely difficult to mimic, which should lead to market exclusivity for years to come. For those of you not familiar with the PERT category, I think it will be helpful to provide some additional color. Prior to April 2008, PERT products were marketed in the full knowledge of the regulatory authorities, absent NDA approval. In that period, there were approximately 40 PERT products on the market. These products were grandfathered in and fell into what we call the DESI category. Between April 2008 and April 2010, FDA practiced enforcement discretion for those firms who had either filed an IND or a New Drug Application, and we're earnestly working toward FDA approval. As of April 2010, the FDA required that all PERT products must have an approved NDA, and subsequently, only 6 products obtained NDA approval. Since these changes have taken place, the average price in the category has increased approximately 57%. The entire PERT market is now doing over $600 million in sales between the cystic fibrosis and GI markets. Although PERTZYE did not obtain NDA approval until May of 2012, PANCRECARB, the previous name of the product, achieved sales of approximately $20 million in 2009. Given the market dynamics, PERTZYE's clear differentiation from other PERT products with Cornerstone's demonstrated effectiveness in commercialization, we believe that peak sales of PERTZYE in the CF market to easily exceed $40 million. By itself, PERTZYE is a strong product. However, what we are really excited about is the synergy and interest that this product combined with BETHKIS will bring into the market. In general, patients with CF experience a significant treatment burden, and we are pleased to bring 2 options, which we believe represent rare steps in the right direction for improving small but meaningful aspects of their lives. As of now, we are one of the only companies that will be providing treatments for the lung and digestive issues associated with CF, which are the 2 major issues that most CF patients deal with on a daily basis. With the acquisition of PERTZYE and the upcoming launch of BETHKIS, we are building a strong portfolio in the CF space, and we'll have 2 new products on the market by Q3 2013. It's important to note that both therapies will be promoted by our specialized hospital sales force, which we plan to expand by 10 to 15 reps. This is yet another strategic step in our commitment to building a portfolio of industry-leading brands for the growing U.S. hospital market. We also believe this further illustrates our commitment to the CF community in helping to ease the treatment burden for those living with this disease. Before I close, I want to let everyone know we realize there are many questions that investors would like answered about the Chiesi proposed buyout. However, we are neither positioned at this time to answer any questions or address this topic. With this, we are ready to take your questions. Operator?
