Thank you, Chane, and good morning, everyone. In HART, we're very pleased to report continued clinical progress. Our current patients continue to do well. Mr. Beyene is alive at 20 months post the surgery. He was given only 2 weeks to live prior to that surgery. The 2 Russian patients, who were the first to enroll in the clinical trial, are also alive at 8 months post-surgery. Those 2 patients were treated as part of the clinical trial funded under a $5 million Mega-Grant from the Russian government and is taking place in Krasnodar in Russia. The Krasnodar Hospital is one of Russia's top hospitals, having performed over 200 organ transplants in the last 2 years. We expect further tracheal transplant surgeries to take place in Krasnodar in the future. In addition to the Russian clinical trial, a European clinical trial in trachea cancer patients, which is expected to enroll approximately 25 patients, is expected to start next year. Before this formal trial begins, individual patients will continue to be treated on a compassionate case-by-case basis in the same way that Mr. Beyene was treated. This project is a consortium of European companies, hospitals and universities led by Professor Macchiarini. I'm also pleased to report that a sixth patient has been treated. The patient is alive at 6 months but is yet to be released in the hospital. The patient was in very serious condition and was treated on an emergency basis as a last-resort attempt to save the patient's life. The patient's current condition has not been disclosed by the hospital. We expect the seventh patient, a young girl born without a trachea, to be treated in the next month or 2. We also expect additional surgeries this year. At this point, the technique is still experimental and can only be used on humans when investigational device regulations have been followed. In December, HART filed a registration statement with the SEC for an initial public offering of shares of HART. We believe that completing an IPO at HART and separating the HART business from the Harvard Bioscience business via spinoff of shares will maximize value for Harvard Bioscience shareholders for the following reasons: the IPO will provide capital for HART's business development; the IPO will put a clear value on HART, and thus will put a clear value on Harvard Biosciences post-IPO, 80% interest in HART. The spinoff will remove HART's operating losses, which were approximately $6 million in 2012 from the Harvard Bioscience income statement, making the profits of the Harvard Bioscience business much more visible. We believe the Harvard Bioscience shareholders will benefit from owning shares in the 2 separate companies by having the continued earnings and cash flow generation of the core Life Science Research Tools business reflected in one security, the common stock of Harvard Bioscience, and the longer-term future potential of the Regenerative Medicine Device business reflected in another, the common stock of HART. The spinoff will give Harvard Bioscience greater borrowing capacity and will allow Harvard Bioscience to focus more aggressively on our core business' acquisition strategy after the spinoff. To that end, we are currently working with our bank group to expand the Harvard Bioscience credit facility. The spinoff will allow each business to focus exclusively on being successful in its own markets without the management team being split between the 2 businesses. HART will continue to provide Harvard Bioscience with an organic growth opportunity even after the spinoff, as HART will grant Harvard Bioscience a license to exploit HART developments in the research markets as HART will focus on providing devices for clinical use. Feeding the research markets with HART technologies sold by Harvard Bioscience will also benefit HART in the long run as it will establish a broad base of researchers already using HART technology as they transition from research to clinical applications. And finally, Harvard Bioscience will retain the tax loss carryforwards, generated by the historical investment of approximately $12 million in HART, which will reduce income tax payments in the few years after the separation, which will improve Harvard Bioscience's cash flow even more than just removing the HART operating losses. Our plan is to separate our Regenerative Medicine Device business into HART, Inc. by: firstly, contributing our Regenerative Medicine Device business assets, including our bioreactors, scaffolds and clinical pumps to it; secondly, contributing $10 million in cash to partially fund its operations; third, raising external capital via the IPO of new incremental shares of HART; and fourth, spinning off Harvard Bioscience's remaining shares in HART to the Harvard Bioscience shareholders, tax-free, approximately 4 months following the IPO. I would like to be clear that this IPO is not an offering of shares at Harvard Bioscience, and we will not be selling any shares in Harvard Bioscience. It is purely an offering of shares in Harvard Bioscience's HART subsidiary. After the HART IPO, Harvard Bioscience will own approximately 80% of the HART shares. After a 120-day waiting period post the IPO, Harvard Bioscience will distribute all of its shares of HART to the Harvard Bioscience shareholders. We expect that this distribution be tax-free to both Harvard Bioscience and to its stockholders. And we filed a private letter ruling request with the IRS to that effect. After its distribution, every shareholder of Harvard Bioscience will receive, via a dividend, shares in HART pro rata to their share ownership in Harvard Bioscience. Following the distribution of shares, HART and Harvard Bioscience will be separate publicly traded companies. Harvard Bioscience's ticker symbol will continue to be HBIO and HART's ticker symbol will be HART. We made considerable progress in the IPO process and have responded to several rounds of comments from both the SEC and IRS. However, the SEC has not yet declared the prospectus effective and the IRS has not yet delivered the private letter ruling. Assuming we receive these approvals in the next few weeks, we expect to begin the IPO marketing process in late March or early April. This will put the dividend distribution sometime in July or August. However, this process is highly dependent on factors beyond our control, including required responses from the IRS and SEC and market conditions, and there can be no assurance that we will be able to obtain a private letter ruling or requisite SEC approvals. Please review HART's Form S-1 filing and its amendments available on the SEC's website. HART has established its own Board of Directors, and I'm very pleased to announce that Tom Robinson, one of the healthcare -- of healthcare executive search company Robinson Butler and former executive at Boston Scientific; and Jim Mcgorry, who led Genzyme's Oncology business for 12 years are now Directors at HART. Both have deep experience in leading and building medical device businesses, and we look forward to working with them in realizing HART's full potential for both patients and our stockholders. We'll now open up the call to any questions.
