Thank you, Todd. Good afternoon ladies and gentlemen. We appreciate you joining us today. With me this afternoon is our Chief Commercial Officer, Dr. Mark Sawicki; and our Chief Financial Officer, Mr. Robert Stefanovich. Later, during this call, Dr. Sawicki will provide you with his comments on our commercial activities; and Mr. Stefanovich will explain our financial results for 2017. Let me start by saying 2017 was a very good year for our company. We achieved many of our goals and entered the next stage of our growth trajectory. Some of our notable achievements throughout the year included upgrading our internal operating systems, adding strength to our bench' of personnel, securing 85 new biopharma clinical trials, and most significantly, announcing that Cryoport had secured long-term commercial logistics agreements to support the world's first two FDA approved CAR-T cell therapies Yescarta by Gilead's Kite Pharma and Kymriah by Novartis. These several milestones cemented our position as the global leader in temperature-controlled logistics, and established a solid foundation for future revenue growth and profitability. There is now doubt we're getting attention in the marketplace, and yesterday, Wired Magazine ran an excellent feature article on our company entitled "Inside the Company Delivering the Next Generation Of Cancer Therapies" which highlights our leadership position, some of our plans, and our advanced technologies. I would encourage you to visit our website to access a link to this article. Now turning to the upgrading of our internal operating systems, we think it is important to invest in advancing our technologies and our people who are most with market-leading competencies. Cryoport's end-to-end solutions are powered by the most advanced temperature-controlled technologies in the life sciences industry including our Cryoport Logistics management platform, our SmartPak II Condition Monitoring System, and our family of Cryoport Express shippers. In 2017, we further expanded our solutions offering with the introduction of our Cryoport Express C3 shippers. C3 standing for Cryoport certified tool supports the front-end of some of autologous therapies that require temperature-controlled transportation within the 2 to 8 degree Celsius temperature range. This is just one example of our commitment to innovation, which is at the core Cryoport's philosophy, and with this in mind, we continue to invest in building out our company's infrastructure and services to ensure we are positioned to support the expansion of our services in our markets of animal health, reproductive medicine, and biopharma. Of course, our fastest growing market today is the global regenerative therapy market which we rigorously support beginning with the scheduled ramp up of Novartis Kymriah and Gilead Yescarta. Gilead recently stated that they had -- they have 28 points of care centers certified and that by mid-year they will have enough of these qualified centers to treat approximately 5,000 eligible Yescarta patients per year. In order to support our current forecast of demand in all of our markets construction is underway for two new state-of-the-art Cryoport Global Logistics centers, one located in the Eastern United States, and the other in the Netherlands. Both are scheduled to open during the first half of 2018. It will support current and new clients as well as anticipated therapy approvals in the European Union and the United States. One example of our growing demand in Europe is our recently announced support of the clinical trials for allogeneic stem cell for the treatment of sepsis. As a result of our continuing investment in research and development, our company remains at the forefront of innovation. We continue to build our reputation in the life sciences or unrivaled technology and services and our markets are continuing to recognize this as evidenced by the growing strength to our client list, to which we added a net total 15 new biopharma clinical trials in the fourth quarter of 2017, brining us to 214 regenerative medicine programs currently supported. We can probably say that no other company in the temperature-controlled logistics industry serving the life sciences can offer the quality expertise, experience, technology, dedicated personnel, and/or customer references that Cryoport delivers. The addition of commercial programs such as Kymriah and Yescarta, along with our new collaboration with McKesson is testimony to the growing strength of our strategy and the dominant competitive advantage we have achieved. Over the course of 2017, we added strength to our bench' of personnel, as we substantially upgraded into the competencies of our commercial, management, technical, logistics, administrative, and service teams. During 2017, we introduced key operating functions vital to our ability to continue to serve our clients with effectiveness and surety. As we secured 85 new biopharma clinical trials during 2017, we further added to our critical mass of biopharma companies having now integrated our logistics solution into their collection and distribution processes in the race to develop new regenerative therapies. Clearly these clients consider Cryoport Logistic Solutions to be an essential component to their cell-based regenerative therapies such as CAR-T cell or B-cell, antibody, and allogeneic stem cell therapies. As I stated earlier, Cryoport now supports a total of 214 clinical trials in the regenerative medicine space, up from 129 trials just a year ago. This increase was driven by new clients as well as existing clients expanding their programs. As we have seen the Novartis and Gilead, these trials represent major embedded revenue growth for our company, as our biopharma client's progress through the clinical phases, and successful therapy candidates ultimately reach commercialization. As a result of the anticipated number of accelerated United States biologic license applications and European Medicine Agency filings from our current clients and based on public reports we are increasing our projected number of combined BLA and EMA filings. Previously, we anticipated supporting two to four additional therapies during 2018; we now think that number is five to seven therapies. With these opportunities, we expect Cryoport's leading position as the logistical backbone for the regenerative medicine industry to strengthen, accelerate, and grow, as we leverage both near and long-term opportunities. We have developed credentials in the area of temperature-controlled logistics that are indisputable with our diversified client portfolio consisting of the very cutting edge of regenerative therapy development encompassing a wide range of therapeutic areas including oncology, hematology, cardiovascular, central nervous system, immunology, infectious diseases, and more. In 2017, we experienced strong revenue growth with the momentum continuing in 2018. Biopharma revenue increased 63% bringing it to 76% of our total revenue for the fourth quarter of 2017. Due to this, we continue to grow our market share in the pre-clinical and clinical market for regenerative therapies. We expect our most significant revenue growth to come from temperature-controlled logistics support agreements for FDA and EMA approved commercial products. As I mentioned earlier, we announced that we signed long-term commercial logistics agreements supporting Gilead Kite's, Yescarta, and Novartis since Kymriah. Our report agreements to support these first-to-market high profile groundbreaking immunotherapies further entrenches our market-leading position and reputation in the biopharma market. As Kymriah and Yescarta are ramped up to full commercialization, they're expected to save many lives, and drive significant revenue growth for Cryoport, who will provide the crucial logistics services to enable these miracles to happen. The signing of these latest contracts pertains to the start of a new wave of regenerative therapies during development and expected to be commercialized over the next several years. To give you an idea of the promise of these new regenerative therapies, according to the Alliance for Regenerative Medicine, $7.5 billion was raised for the development for regenerative therapies in 2017 compared to $4.2 billion in 2016, an 80% increase year-over-year. We announced last week a strategic collaboration with McKesson Specialty Health to support the delivery of cell and gene therapies to patients at points of care. Both companies recognize the complex support, ecosystem that is emerging as regenerative therapies reach commercialization, and we think, our collaboration underscores Cryoport's leadership position and growing reach. This new relationship will allow us to further extend and amplify our cold chain logistics expertise with McKesson's end-to-end patient access and support services focused on assisting patients entering treatment through accelerated patient on-boarding, prior authorizations, and educational support programs. Now turning to Animal Health and reproductive medicine, our technologically advanced logistics solutions and first-in-class reputation around the world also drove significant revenue growth in these two important markets during 2017. In 2017, our Animal Health plan continued to include established names such as Zoetis, Vetstem, and Boehringer Ingelheim. We concluded 2017 with $1.1 million revenue for a 34% revenue growth in our Animal Health market. In reproductive medicine, we enjoy excellent relationships with more than 400 fertility clinics worldwide and concluded 2017, with $1.7 million of revenue or 11% annualized growth. In effect, there is work in the reproductive medicine market, including technological advances and combating infertility as well as managing fertility. Subsequently, an increasing number of cases are driving an increasing demand for our solutions, especially in the United States. You might have noticed that we recently branded our IVF Services as CryoStork and as a matter of priority; we're directing our sales and marketing efforts to our CryoStork Solutions to meet the largely unmet need for premium quality cryogenic logistics solutions in this growing market. Both Animal Health and reproductive medicine are consistently growing markets and sources of revenue that we plan to expand throughout 2018. Now, Dr. Mark Sawicki, our Chief Commercial Officer, will provide further details on the particulars of our market. Mark?
