Thank you, Courtnee and welcome to all of you joining us this afternoon. Today, speaking on the call besides myself, we'll have GCI Liberty's CFO, Mark Carleton; and GCI CFO, Pete Pounds. Also during the Q&A, we will be available to answer questions related to Liberty Broadband if there are any. So, starting with GCI Liberty, at the corporate level, we continued share repurchases. Between November 1st and January 31st, we repurchased over $100 million worth of stock. We aim to take advantage of a double discount at GCI Liberty, the low -- and the low Charter price. That double discount is because you look through with the discount GCI Liberty has to Liberty Broadband and in turn, Liberty Broadband has to Charter. To date, if you look at that double discount, we've effectively repurchased a Charter on average look-through price of around $270 and that look-through price today is up to $290, and obviously, Charter itself is considerably higher. So, we're excited about trying to take advantage of both, the growth in Charter and that double discount. Turning to GCI, 2018 was undoubtedly a challenging year. We operated in a difficult business environment and a difficult regulatory environment. Nonetheless, GCI completed several critical business initiatives we believe will set us up better for the future and we look forward to a more favorable business environment in 2019. You'll hear more about that from Pete Pounds shortly. Over at Liberty Broadband, Charter finished the year strong and performed well in 2018. Charter's footprint is now upgraded to all digital and has access to the spectrum Internet gig service. We saw strong residential growth across residential, commercial, and advertising. We ended the year with our -- after our launch of mobile with 134,000 mobile lines and we expect to accelerate that dramatically in 2019. Charter repurchased $5 billion of its own shares in 2018 at an average price of $309. Notably, CapEx is expected to decline to $7 billion in 2019, a dramatic decrease over what we spent over the last couple of years. All in line with our thesis in the long-term, Charter can have the most attractive and CapEx profiles in the industry. Charter remains and we're excited about the fact it is a levered free cash flow story with a potential for significant equity shrink. So, with that, let me turn it over to Mark Carleton to discuss the financials in some more detail at the GCI Liberty level.
