Thank you, Marty, and welcome, everyone. I’m glad to be on the call with you today. With the release of our Q4 results and to look back at the full year, it is clear to us 2018 was a seminal year for NICE. Our cloud business prospered with Q4 cloud revenue growth of 29% fueled by early adoption of CXone in the market place. Some key metrics that underscore 2018 as a milestone year included 9% total revenue growth, 27% cloud revenue growth and recurring revenue increasing to 70% of the total revenue. We reported 13% operating income growth, a 90 basis point improvement in the operating margin, and 14% increase in earnings per share and nearly $400 million of operating cash generated for the year. Further more, we saw a record number of new customers and significant increase in the number of competitive replacement. As we look forward to 2019 and into the next five years, it also gives us the opportunity to look backwards over the past five years and at what we achieved during this time. It was a period in which we transformed NICE into a true enterprise software company. It was also during this time that we move from being a leader in maturing market to a leader in a total addressable market of $7 billion to date going quickly to over $12 billion. We've accomplished this by bringing together what we believe to be the greatest assembly of assets in the industry that has allowed us to significantly scale on our analytics and cloud businesses to become the clear leader in both areas, At the same time with a keen focus on operational excellence, we are able to accelerate top line growth while significantly improving profitability. Now with all the right assets in place, we have successfully delivered two profoundly differentiating platforms in the market with CXone for customer engagement and X-Sight for Financial Crime and Compliance. With these two platforms and the large total addressable market into which we can continue to expand, it is no longer suitable just talk about leadership. Rather and more importantly it is time to talk about the opportunity to become de leader. And what do I mean by this. The de leader delivers truly differentiated products and superior and complete offerings as we have done with our two platforms. This causes de leader to become the clear choice of customers which leads to more R&D investment which then again turns into more differential products and complete offering. It becomes a petro cycle that continues to further support de leader position in the market. Eventually, the ecosystem grows very large and de leader gain the capacity to cover all markets, geographies and enterprise all side of at significant competitive advantage. So how do we become de leader? We already have the wide lead in both market share and product offerings. This gives us the advantage to continue to disrupt the status quo by aggressively moving forward for continued rapid innovation, sound execution and still differentiating NICE from our competitors. In customer engagement, we will expand CXone, making it an even more comprehensive offering than it is today. We further grow the CXone ecosystem and drive our open cloud platform into the market for geographic expansion, deeper penetration into our customer base and by bringing it to businesses of all sizes. We expect to see CXone as the clear choice among all enterprises. We will further inject powerful analytics into everything we do and to do --and further recommend analytics by using AI throughout our analytic solutions. We call these our analytics everywhere approach. Moreover, we will be delivering more AI fuel productive analytics in 2019 and beyond. In Financial Crime and Compliance, we are only at the beginning with X-Sight. Our goal is for X-Sight to be the clear new standards for financial crime and compliance customers. Like CXone, X-Sight allows us to cater to all market segments in the cloud. We already have solutions like Actimize Watch and the recently announced IFM-X on X-Sight. IFM-X is our next generation integrated fraud management suite that uses automation and machine learning to optimize effectiveness and reduce total cost of operating a fraud risk management system. With X-Sight, we are becoming a market facilitator for sharing data across financial services organization. Another building block of our strategy is robotic process automation. We will continue to differentiate ourselves in the robotic software market, where we're experiencing rapid growth. This is a market that is still in its infancy. And we are well positioned for differentiating solutions such as our leadership in Attended RPA, Neva, which is our one of a kind a attended robotic assistant and automation finder in AI product solution that detect processes and enterprise that are perfectly suited for automation. As we march towards the goal of becoming de leader in our respective markets, we can now look forward to five years into the future. We expect to far exceed the $2 billion revenue mark to see the majority of our revenue come from the cloud and to have greater than 30% operating margin. Our Q4 execution provides a glimpse into our march ahead. In Q4, CXone presence in the market continued to spread as we have firmly established NICE as the only provider of a true open cloud platform that seamlessly combine omni channel routing, WFO analytics under one umbrella. We're getting multiple high marks from industry analysts and just earlier today, we announce the Gartner has positioned NICE highest as de leader in the MQ for -- engagement management for the third consecutive year. But more importantly, we're seeing evidence of the continued growth of CXone within our customer base and among new customers. Some large CXone deals in Q4 included a seven digit deal with the state government that had been a long time on -premise customer with an incumbent that really placed as the state government is quickly bringing on CXone to support their expanding number of agencies. There was another seven digit CXone deal with one of the largest state employment retirement systems in the country. We replaced the incumbent on-premise provider that the retirement system is mandate rapidly move off of on-premise contact center, they needed technology in the cloud that can accommodate their current and future needs. Other seven digit CXone replacement deal included a very large mission fund manager, a federal government agency and IT services firm and an online retailer. Analytics is another area where we continue to see strong growth in one in which we believe will continue to outpace the market with cutting edge technology. This includes recently announced new solutions like back office proficiency essentials which infuses the combination of depth of analytics together with performance management that enables organization to enhance employee performance. And then there is our newly announced customer journey excellent score, which is an AI Pod metric that provides organization a consistent means of measuring service quality across touch points over time. And enables the prediction of future outcome. In fact, NICE was recognized as a leader in customer journey analytics in two reports by Forrester Research. We signed a seven digit deal with an alternative payment provider for a portfolio of solutions including Nexidia analytics and compliance center. There was a seven digit deal with a very large insurance services company to provide analytic driven insight to improve operational efficiency and customer satisfaction. And there was a seven digit deal with a major airline for Nexidia analytics to help them up sell revenue, reduce costs and perform in-depth analysis. Other analytics deal included a seven digit with an international bank for our AML suite and another seven digit deal for both fraud and AML was the leader in prepaid credit card solutions. We witnessed continued strong momentum for Actimize Watch which is cloud based solution that uses contortion data and state -of-the-art machine learning and artificial intelligence for further AML. In one example, we signed a seven digit Actimize Watch deals with a very large international bank. Essential, our cloud based fraud and AML suite also did well including a seven digit deal with a new customer, a large credit union we will replace incumbent. In Robotics, we signed a record number of new logos in 2018, and continue to see rapid growth in this line of business. We signed several seven digit RPA deals including one with a very large telecom company, one with the home services company and one which was part of the large deal with a major healthcare company. In fact, the total deal size for this healthcare company was in the eight digits and comprises a number of different solutions including multiple analytics and competitive replacement of real timeout indication In closing, we are very pleased to end the year on a high note but now are also the time to looking to 2019 and beyond. CXone and X-Sight are our leadership platform and are sustainable, sustainable, long- term differentiators to help us become de leader. As the market continues to shift to the cloud and specifically to platform, we're in great position to capitalize on the many opportunities ahead. I'm also looking forward to seeing you in April interaction, our annual user conference which is the largest in our industry. We are expecting the record number of customers in attendance this year. I also want to take this opportunity to thank all of our employees around the globe for their outstanding commitments to our strategy and their contribution in making 2018 another successful years for NICE. I will now turn the call over to Beth to review our financial results.
