Will Lyons - IR: Thanks, Sam. Good afternoon, everyone, and welcome to TripAdvisor's Fourth Quarter and Year End 2013 Earnings Conference Call. I'm Will Lyons, Senior Director of Investor Relations for TripAdvisor, and joining me on the call today are our CEO, Steve Kaufer; and our CFO, Julie Bradley.
Before we begin, I'd like to remind you that estimates and other forward-looking statements included in this call represent the Company's views as of today, February 11, 2014. TripAdvisor disclaims any obligation to update these statements to reflect future events or circumstances. Please refer to today's earnings release and TripAdvisor's filing with the SEC for information concerning factors that could cause actual results to differ materially from those expressed or implied by such statements.
You'll also find reconciliations of non-GAAP financial measures to the most comparable GAAP financial measures discussed on this call in our Q4 earnings release, which is available on our IR site, ir.tripadvisor.com.
Finally, unless otherwise stated, all references to selling and marketing expense, general and administrative expense and technology and content expense exclude stock-based compensation and all comparisons on this call will be against our results for the comparable period of 2012.
With that, I'll now turn the call over to Steve.
Stephen Kaufer - CEO: Thank you, Will, and welcome, everyone. 2013 ended on a very strong note punctuated by a broad based growth across our entire product set. Growth to our click-based and display-based revenue accelerated sequentially in Q4 and was complemented by continued growth in subscription transaction and other revenue. This resulted in full year total revenue growth of 24% and adjusted EBITDA growth of 7%.
We are very pleased with our financial results, but are even more excited by our continued strong traffic and content growth given our global scale as well as successfully transitioning the core business to meta, a transformational part of improvement we made to dramatically enhance the hotel shopping experience on TripAdvisor.
Top of the funnel metrics remained strong as total traffic to TripAdvisor sites grew 50% during the quarter and 55% for the year, with more than 2 billion unique annual visitors in 2013 according to Google Analytics, a testament to our global brand building efforts and powerful network effects.
Hotel shoppers grew 25% in the quarter to 36% for the year, with notable strength in our core U.S. and U.K. markets. Internationally, we rolled out four new points-of-sale in 2013, and we are planning to roll out eight more in 2014, delivering a more localized experience to international users.
Our members are more engaged than ever, contributing nearly 50 million reviews and opinions in 2013, increasingly coming from international users and foreign languages and via mobile devices. We recently launched new member profile pages on our website, more prominently showcasing the members' contributions and iconic bubble ratings, a theme that also shines through in our (full) site brand refresh and our TV ads.
