Thanks, Jennifer, and good afternoon everyone. So I am excited to talk to you about the progress Etsy’s made in 2015, our plans for 2016 and our financial goals through 2018. In the fourth quarter, our GMS was more than $741 million and our revenue was nearly $88 million. For the full year GMS reached nearly $2.4 billion and revenue was more than $273 million. We believe our strong results reflect the vitality of Etsy’s community and our team’s strong execution. Throughout 2015, our community continued to grow and we ended this year with more than 24 million in active buyers and nearly 1.6 million in active sellers. In 2015 we continue to put the building blocks in place that we believe will set us up for sustainable long-term growth. Buyers on Etsy’s platform remain uniquely loyal to the brand. In 2015, 81% of our GMS came from repeat purchases made by new, retained, and reactivated buyers. This was up from 78% in 2014. Also in 2015, approximately 47% of our active buyers made two or more purchases in the previous 12 months, up slightly from 2014. We believe that these two data points shed important light on our long-term growth opportunity. First, we know that Etsy buyers are loyal and have continued to make repeat purchases over a long period of time. Second, with fewer than 50% of our active buyers making multiple purchases in a single year over the long-term we believe we’ve made or we have substantial opportunity to drive engagement which ultimately should lead to increased purchase frequency. Our community of sellers and buyers who are so important to our long-term success continue to show their loyalty to Etsy. Kristina will provide you with new 2012 seller and buyer cohort data that further demonstrate their commitment to our platform. With approximately 90% of our traffic coming from organic channels, Etsy’s brand clearly resonates with buyers. During our third quarter earnings call we talked about our strategy to implement a multichannel holiday campaign to grow brand awareness beyond our organic channels and to drive engagement throughout the fourth quarter holiday season. We ran a coordinated campaign across paid and non-paid channels that helped our sellers to have a great holiday season. We saw strong returns on our digital marketing budget and as Kristina will describe, paid GMS growth that significantly outpaced organic GMS growth. More importantly, our overall GMS growth accelerated as we moved through the holiday season in November and December evidence of the successful brand campaign. For the first time ever, we ran a global holiday campaign that featured merchandised pages and gift guides across key categories and was coordinated across mobile apps, desktop and global Web. We ran a cost effective video ad on Facebook and YouTube and were featured on Ellen Degeneres Show’s 12 days of Christmas segment. We complement our brand campaign with a robust e-mail and social media effort that included nearly 20 million push notifications nearly 900 million e-mails and Facebook and Instagram social media campaigns. 2015 was a strong year of growth for Etsy and I believe we're executing the right strategy to build sustainable growth for the long-term. So let me take the next few minutes to talk about what we have recently achieved in each of our key initiatives and some of the upcoming milestones that will be indicative of our continued forward progress. Let's start with Etsy every day, mobile is at the heart of this initiative and in just one year we improved the Etsy mobile experience from end-to-end. We developed products and tools that allow our buyers and sellers to connect and transact more seamlessly across multiple devices, countries and currencies. Our top focus in 2015 was to help buyers find and use our beautiful Etsy apps and connect them directly to an easier and more fun than ever mobile experience. We believe this foundational work improved the experience across the buyer journey and contributed directly to our apps GMS growth which grew well over 50% in 2015. Our first step included the work we did around deep linking and app indexing which allows us to connect shoppers directly to our apps. Once in the app we made it easy to get started with social sign up and sign in via Facebook and Google. We also introduced an important update called exploratory search, this enhancement helps buyers to more easily find the items they're looking for on Etsy by making search results and navigation more intuitive to buyers, who can now browse by category, feature or product type. Finally, we expanded the checkout experience using Etsy’s direct checkout platform which now offers integrated Apple Pay, Google Wallet, PayPal and Express Checkout payment options. We believe these core improvements and others led to our 4.5 star rating in the Apple app store up from roughly 2.5 stars prior to this work and also contributed to the continued growth of app downloads which reached 31.8 million as of December 31st. While we're still in the early innings on mobile we believe that we've made an important progress in a relatively short period of time. The impact of this work is best seen in the year-over-year narrowing of the gap between mobile visits and mobile GMS. We began to see this in the third quarter and it continued in the fourth quarter. In the fourth quarter 61% of our visits and 44% of our GMS came to Etsy through a mobile device. We believe we can continue to close the gaps between mobile visits and mobile GMS and benefit from the emerging trends in mobile commerce. Our efforts in mobile in 2015 moved the ball forward for Etsy and provided strong momentum as we head into 2015. This year we plan to launch even more mobile products, tools and services that address the needs of our diverse community of sellers and buyers. As our teams continue to execute on our exciting 2016 product road map, you should expect to see more enhancements to help Etsy sellers or Etsy buyers connect with sellers in new ways and enable them to more easily find a unique item they're searching for, at just the right time. Turning to our international initiatives to build more local marketplaces globally, we made our first international sale in our first week of business over a decade ago and Etsy global business has grown since then. Even with that growth we believe we're only at the beginning when it comes to our international strategy. In the fourth quarter 29.2% of our GMS with some international sales roughly flat with the third quarter, as we've discussed in previous quarters, currency has a direct translational impact on our results and we believe an indirect impact on the behaviour of international buyers. We're working hard to offset these macro currency challenges by building local marketplaces and ecosystems. Our continued strong growth in the UK reflects the early success of this strategy. In the fourth quarter in nearly half to GMS in the UK works on UK buyers purchasing from UK sellers, evidence that we're building a local marketplace within the country. To give you some prospective in the U.S. our most mature market for approximately 78% of GMS is from transactions between U.S. buyers and sellers. Purchases by UK buyers and UK sellers grew more than 69% year-over-year nearly 7 times the growth rate of purchases made by UK buyers and sellers outside of the UK in the quarter. We believe that new enhancements like the boost of domestic items within search which we launched in the UK in the fourth quarter encouraged the factor being of particularly helpful during the holiday season. GMS between international buyers and sellers in the same country is one of our smallest GMS buckets, so we believe we have substantial Greenfield opportunity to grow in local marketplaces internationally. In 2016 we'll continue to invest in local marketing content and program tools to expand our international community and broaden on our global platform. Great examples of these efforts are already underway are programs like Etsy Resolution and Etsy Made Local. Etsy Resolution is our seller acquisition campaign aimed at driving new seller growth in our international markets. We've launched this four week mentoring program at the end of January and more than 26,000 participants signed up within the first week. Etsy Made Local was a series of local markets organized by Etsy seller teams, our Etsy Made Local events in Australia were particularly successful and attracted 65,000 people across the country. Turning now to our high impact seller services, which represented 54% of our revenue in the fourth quarter, you may recall that we launched the first of our three seller services late in 2011 and in less than five years our three services now make up the majority of our revenue base. We believe this rapid growth demonstrates our ability to address the pain points that sellers encounter whether they’re just starting out and are trying to grow. We intend to continue to grow seller services revenue by expanding the geographic reach of existing services, enhancing the functionality of our existing services, and building new services. We have two recent examples that demonstrate our execution on this strategy. At the end of October we enhanced the functionality of direct checkout by fully integrating PayPal into our service and making it even easier for buyers and sellers around the world to seamlessly transact. Following this integration, we saw direct checkout revenue growth accelerate in the fourth quarter. And in early 2016, we enhanced direct checkout even further by scanning into an additional 12 countries and integrating Apple Pay into our express checkout option. As we look ahead to 2016, we intend to launch a new seller service. While we’re not announcing the specifics of this new service today, we remain focused on helping our sellers with the business related task such as inventory management, shipping, customer service, marketing and accounting. As we outlined in our IPO perspectives for every hour an Etsy seller spends making her product, she spends another on these tasks and we want to help our sellers find more time to create. So our product roadmap is focused on services that will help her manage these types of tasks, increase velocity of our marketplace and at scale provide an attractive profit opportunity for Etsy which we can reinvest back into our business and our community. As we think about our longer term roadmap for seller services, we’re looking at opportunities to support our sellers wherever and however they chose to bring their products to market. As we said before, based on our surveys and research, we know that more than 50% of our sellers sell in channels other than Etsy even though Etsy is their largest source of income. Other channels include craft fair, their own Web sites and retail outlets just to name a few. In the same way that these other channels provide new opportunities for them to seller their products, they also add to the administrative workload. We believe we can develop tools and services to help our sellers better manage these multiple sales channels. Overtime this presents a significant opportunity for Etsy to enhance the value of our platform for our sellers and to expand our addressable market opportunity. Finally, I want to touch on our efforts to expand the Etsy economy which focused on broadening the impact of our platform by bringing new constituents into our community. We talked to you before about Etsy Manufacturing and Etsy Wholesale and our long-term vision for their contributions to our ecosystem. As we announced last quarter we launched Etsy Manufacturing in direct response to feedback from our sellers who told us they wanted to grow their businesses they were having difficulty finding production partners with similar values. Through our platform these sellers can now connect with values aligned manufacturers that range from individuals to emerging start ups to decade old family run factories. It’s still early days and to-date we have received around 700 applications from manufacturers to join the marketplace. Approximately 25% of those applicants have actually been from current Etsy sellers who are offering to help other sellers produce their products. Throughout 2015, we also reached core milestones that we believe will help make Etsy Wholesale an important tool for our sellers in the years to come. First, we exited 2015 with nearly 11,000 retailers and more than 4,500 sellers signed up to participate in Wholesale. Our goal is to make Wholesale more accessible to creative entrepreneurs and to support these smaller independent retailers as creative business owners. Second, we introduced the Etsy Wholesale retailer commitments with our larger retail partners. Land of Nod, Lou & Grey, Whole Foods and our newest partner Macy's Herald Square with whom we launched the new Etsy shop on January 28th. These commitments are focused on supporting our seller community by reducing the operational and financial challenges they face when working with larger retailers. While I am proud of what we’ve accomplished to-date the Etsy team and I are really focused on execution and excited about the opportunities and milestones yet to come. We believe we have the right strategy in place and passionate leaders to execute on it. We’ve made prudent investments to maximize the impact of this strategy. We also believe that we have an unrivaled understanding of the needs of creative entrepreneurs which will allow us to grow with each of them, supporting their individual needs. All of these factors give us confidence in our long-term growth potential and our ability to deliver value to all of our stakeholders. In 2016 to recap this means the roadmap that includes products that will continue to encourage buyers to engage, browse, search, and discover unique items platform enhancements that will make it even easier for buyers and sellers to seamlessly and quickly transact and the new seller service that solves the pain point and moves us down the path toward our longer term goal of supporting our sellers wherever they put ecommerce. We’ll also be launching new tools and products to continue to support our international strategy to build local marketplaces and expand the Etsy economy. So with that I’ll turn it over to Kristina to walk you through our 2015 results, and provide you with a bit more context on our three year financial guidance. Kristina?
