Thank you, Eilif. Let me start with a summary of our financial performance for the quarter, starting on Page 7. Revenue in the fourth quarter was $914 million. Adjusted EBITDA was $229 million, which as Eilif noted, was ahead of expectations. On a comparable basis and at constant currency, our revenue and adjusted EBITDA for Q4 grew respectively 2% and 6%. Let's now review in more detail our operating metrics, starting with enrollments, which you will find on Page 10. Overall, we grew new enrollment by 6% for the year, while total enrollment increased 1%. Here are some highlights by segments. And let's start with Brazil, which continues to perform very well for us. Our Distance Learning business grew new enrollments year-over-year by 75% for the full year, which was well above expectations and is a result of the investment we have been making in order to bring this strategic operating segment as closely as possible to scale. Although new enrollment for our campus-based operations were flat, all payer segment grew 6%. This was completely offset by the continued reduction of our new enrollment associated with government-sponsored programs, like Fies. In Mexico, performance continues to be missed and is consistent with what we've seen in prior quarters. The eroding consumer confidence continues to impact the higher education sector overall. Despite these challenging market conditions, our UNITEC brand is still growing thanks to geographic expansion initiatives outside of Mexico City, as referenced by Eilif earlier in his remarks. Our Andean segment delivered solid performance, mostly led by our large institution in Peru, mainly UPC and UPN. In our rest of the world segment, our business in Australia is doing extremely well, with 8% growth in new enrollments. Finally, in Online & Partnerships, our domestic new enrollments grew 3%, which was more than offset by the contraction of enrollment outside of the U.S. These results were expected and reflect the gradual deemphasis of our international students through our Walden brand and our partnerships in the UK Now let's move to our financial performance, which you will find starting on Page 11. Full year results were ahead of guidance, with adjusted EBITDA at $623 million for 2018, representing a 7% growth versus 2017 on a comparable basis and at constant currency. Our overall results were driven by strong revenue performance in Andean and Australia as well as margin improvements fueled by the benefits of our cost-containment action across all of our operating segments and at corporate. All of these strong results contribute to an 89 basis point increase in margin on a comparable basis, which keeps us well on track for meeting our medium-term margin guidance of at least 21% by 2020. Let's now move to our cash flow performance, which was well ahead of expectation and is illustrated on Page 13. As a reminder, please note that our cash flow statement include the impact from continuing and discontinued operations. Overall, free cash flow generation for the year reached $139 million, which was significantly ahead of our guidance of $100 million we communicated at the beginning of 2018. This represents almost $0.25 billion improvement year-over-year, despite a $30 million headwind associated with FX. Cash flow from operation and interest expense reductions were the 2 main contributors to this dramatic cash flow improvement versus 2017. Finally, please note, that $20 million of our cash flow performance was related to the favorable timing of early collection in Australia and the deferral of severance payments to 2019. In summary, 2018 was an outstanding year for both margin and cash flow improvement. This has been a total company performance and sets up very well for 2019. Let's move now to our 2019 guidance, starting on Page 19. For the full year, total enrollments are expected to be approximately 890,000, which represents a growth rate of approximately 2%. Revenue, based on current spot FX rate, is expected to be between $3,350 million and $3,385 million. This represents an organic constant currency growth of 2% to 3%. Adjusted EBITDA, still based on current spot FX rate, is expected to be between $645 million and $655 million and would represent a 7% to 8% growth on a comparable basis. Please note that this adjusted EBITDA does not include the full benefit of our G&A reduction following the divestment of our assets in Asia, EMEA and Central America. If you factor all of these savings in on a full year basis, adjusted EBITDA for 2019 would be around $675 million or a 12% increase versus 2018. Free cash flow, based on current spot FX rate and defined as operating cash flow less CapEx, is expected to be approximately $145 million for 2019. Finally, from a capital structure perspective, based on current spot FX rate, we expect to end 2019 with approximately $800 million of net debt. Now let's move to the first quarter. Our guidance based on current spot FX rate is as follows: Revenue is expected to be between $605 million and $615 million. We expect adjusted EBITDA for the first quarter of 2019 to be a loss of approximately $24 million to $28 million. This is consistent with our prior year's revenue and earnings seasonality and reflects the fact that most of our institutions are out of session for much of the first quarter. Lastly, following popular demand, please note that later today, we will be filing an 8-K with our historical quarterly results, revised for the current presentation of continuing operations. We hope that this supplemental information will be helpful to investors as they continue to develop a better understanding of our historical performance on a comparable basis. Let me now turn it back to Eilif for the wrap up.
