Thanks Natasha. As we look back at fiscal year 2017 and reflect on our performance, I'm pleased with the progress we've made in executing our strategic initiatives. We've made advances across all three of our key priorities including furthering our regulatory efforts, identifying compelling customer use cases for our spectrum, and increasing sales of our DispatchPlus solutions. Our strong cash position has provided us the opportunity to continue investing in these activities. We remain confident that our business strategies will over the long-term lead to regulatory success which will in turn expand the usability and capacity of our license spectrum and ultimately result in contributing additional revenue and improvement of our operating results. I expect that by continuing our focused on these priorities, our team will deliver significant shareholder value. Looking ahead to fiscal 2018, I'm excited about our prospects. Now I'd like to provide an update and our initiatives over the course of the fourth quarter. Starting with our DispatchPlus business, I'm happy to report that we closed the fourth quarter with our strongest quarterly net unit additions since launching less than two years ago. We beat our third quarter net additions by close to 90%. As of today we stand at just over 4700 units and service, an increase of over 1100 units since our last call in February. As evidence of the value of our solution in a multitude of businesses, we continue to see customer wins across the verticals we've been targeting. Those include school buses, private ambulance and transportation services. Overall, we've learned a great deal about the market, the effectiveness of our product, the performance of our dealers, and the needs of our customers. We look forward to replicating these use cases with more and more prospects during our current fiscal year. We also added some additional sites within our market areas to expand coverage for our customers and prospects. In addition, in the past we discussed the challenges we've had with the ramp-up of our two-way radio dealers along with the importance of implementing additional distribution capabilities. We've begun to make progress on that front. While it will take time to convert this into increased revenues, we recently formed strategic partnerships indebt increasing our distribution in both the Fleet Telematics and the Telecom Master Agent space. There are clear and natural synergies between ourselves and these new partners and we expect our solutions to match up well with their offering including real-time data analytics and machine-to-machine communications. By adding these new partners now, we can extend our offerings to a broader range of new customers and provide linkage to our wideband and broadband effort which in turn will help build long-term value. In addition, we are supplementing our indirect dealer channel with increased direct sales personnel in certain markets and we continue to see positive results from our centralized business development team. Relative to the DispatchPlus business, it is our intention to remain focused on our current seven markets for the near-term while we advance our regulatory initiatives and increase our commercial outreach to potential customers in the critical infrastructure industry. As our business continues to evolve, so does the insatiable demand for wireless solutions. As we all know, spectrum is a finite resource and as such it is incumbent upon holders of spectrum to utilize the innovative and efficient technologies. During the last year, we continued evaluating technology solutions that will utilize our spectrum in its current configuration and also in its future configuration assuming regulatory success. For example, we successfully tested our current spectrum in endpoint devices which would allow us to serve customers with an enterprise grade field area network solution. We also continue to evaluate broadband solutions including exploring the development of a 900 megahertz virtualized LTE network that could address the needs of future critical infrastructure and enterprise customers. This approach could empower these potential users to create and implement their own virtual private networks slice from a secure hosted cloud environment allowing them the control and security benefits of our private network with the technology advantages and cost-effectiveness of a shared network. As another example, we are working with critical infrastructure community addressing the communication needs related to key elements of modernizing the smart grid including field area networks, sensors and meters and similar endpoint devices that may perform best on a private wireless network using licensed spectrum. As a wireless carrier with a nationwide spectrum position, we view our DispatchPlus services as the first layer of applications on our enterprise focused private network. Modernizing and realigning of our spectrum band will only increase its usability and capacity further enabling us to explore exciting new possibilities including the future deployment of broadband and other advanced technologies and services. We believe that security, priority access, control and customization requirements are just some of the reasons critical infrastructure and enterprise customers will be interested in obtaining the private network services we plan to deploy if we receive FCC authorization. Morgan will provide an update on these efforts shortly. Before that I want to share some additional progress we've made in expanding our Board leadership team. In May, we were pleased to announce the appointment of Mark Hennessy to our Board of Directors. Mark joins Paul Saleh as the second Board member we added in the past year as part of our continued effort to add relevant skills, experience and independent thinking to our Board. Mark recently retired after a 34-year career at IBM where he served in a number of executive management positions. During his tenure, he was responsible for global integration initiatives and technology operations focused on innovation and growth. He brings a strong background of strategic business development and operational excellence, as well as a deep knowledge of global enterprise technology. We look forward to his contributions on our Board. Now I'd like to turn it over to Morgan O'Brien our Vice Chairman to provide a more detailed update on our regulatory initiatives.
