Thank you. Good morning, everyone. Thank you for standing by and welcome to OMA's fourth quarter 2018 earnings conference call. We have today, Ricardo Dueñas, OMA's Chief Executive Officer; and Ruffo Pérez Pliego, Chief Financial Officer. They will be discussing OMA's fourth quarter 2018 results announced yesterday. Please be reminded that certain statements made during the course of our discussion today may constitute forward-looking statements, which are based on current Management expectations and beliefs and are subject to a number of risks and uncertainties that could cause actual results to differ materially, including factors that maybe beyond our control. I will now turn the call over to Ricardo Dueñas.
Ricardo Dueñas: Thank you, Emmanuel. Good morning everyone and thank you for joining us today. I am very pleased to be here with you this morning and it's a great honor for me to take part of this new challenge as OMA's CEO. I will work very hard to ensure continued success of OMA, development in the coming years and I look forward to meeting and speaking with all of you. I will start by briefly reviewing our fourth quarter operational results. OMA delivered record financial results and operating results in the fourth quarter of 2018 and record results for the full year. Adjusted EBITDA grew 22% in the quarter and adjusted EBITDA margin reached 70%, largely as a result of our cost cutting initiatives and our actions to increase both aeronautical and non-aeronautical readiness. For the full year, OMA generated the highest levels of revenue, adjusted EBITDA and net income in our history with double digit growth in all these categories. OMA also recorded the highest full year adjusted EBITDA margin in our history, 70%. One of the keys to our performance besides additional passenger traffic was to keep a tight rein on costs and expenses through the implementation of cost cutting initiatives in 2018 aimed at reducing overhead expenses. For the full year, cost of airport services and G&A decreased 2.5%, with decreases in most line items. Our cash flow generation was strong with 12 month cash flow from operations reaching MXN3.7 billion. This enabled us to fund our master development program and strategic investments, as well as the payment of a dividend out of funds from operations. OMA has now delivered 36 consecutive quarters of growth in aeronautical and non-aeronautical revenues and 30 quarters of adjusted EBITDA growth. Passenger traffic reached 5.3 million passengers in the fourth quarter that is up 10.4%. 10 airlines increased passenger volumes. The largest contributions to growth came from VivaAerobus and Volaris. Total available seats increased 9.6% as airlines have deployed more capacity and increased frequencies particularly on the high volume routes. On our single highest volume route, Monterrey, Mexico City, total available seats grew 15% compared to the fourth quarter of 2017. On four other high volume routes in the quarter, Monterrey -Cancun, Monterrey-Guadalajara, Culiacán- Tijuana and Chihuahua-Mexico City, the total available seats also grew a combined 15% versus the fourth quarter of 2017. Additionally, airlines opened 17 routes in the quarter while 6 closed. On the commercial front, we implemented four key initiatives in the quarter including a new advertising service contract, as well as new food and beverage outlets primarily. Commercial revenue grew 13% and the occupancy rate for commercial space in our terminals was 99%. Diversification activities delivered a solid performance with revenue growth of 7%. The Monterrey Industrial Park continues to develop with 6 leased warehouses generating revenue. Total investments in the quarter including the master development plan investments, major maintenance, and strategic investments were MXN342 million. Major projects under way include a new passenger terminal building in Reynosa, expansion and remodeling of the Chihuahua and San Luis Potosí terminal buildings, construction of remote commercial aviation platforms in Monterrey, and work on runways, taxiways and aviation platforms in several airports. The Chihuahua and Reynosa terminal project are scheduled to be completed in the second and third quarter of 2019 respectively. This passenger terminal projects will enable OMA to provide better service to our airline clients, improve the passenger experience, and increase our leasable commercial space. We expect that these investments will help OMA continue on our path of higher aeronautical and non-aeronautical revenues. I would now like to turn the call over to Ruffo Pérez Pliego, who will discuss our financial highlights for the quarter.
Ruffo Pérez Pliego: Thank you Ricardo, good morning everyone. I will briefly review our financial results and then we will open up the call. Turning to OMA's fourth quarter financial results. Aeronautical revenues increased 20% mainly because of passenger volume growth. Aeronautical revenue per passenger increased 9% in the quarter. Non-aeronautical revenues increased 10% with commercial revenues making the largest contribution to growth. Commercial revenues increased 13%, and the best performing categories were car parking, VIP lounges and car rental. Car parking revenue was up mostly because of restructuring capacity in the Monterrey, Chihuahua and Reynosa airports, as well as passenger volume growth. VIP lounge revenues grew 73%, largely as a result of the opening of 3 new lounges during 2018 including our brand new VIP lounge in Terminal B of the Monterrey airport that opened in November. Car rental revenues rose 16% because of the leasing of 23 new rental locals throughout 2018, as well as improved contractual terms. Diversification activities grew 7% mostly driven by revenues of Industrial Park. Complementary services increased 10% with main factors being additional passenger traffic, as well as inflationary adjustment in rates. As a result, total aeronautical and non-aeronautical revenues reached MXN1.7 billion. Construction revenue decreased 32%. This is non-cash item that is required under applicable accounting standards. It is equal to construction cost of improvements to concession assets so it has no effect on earnings. OMA's initiatives to reduce costs implemented throughout the year were also a major contributor to our results in the fourth quarter. The cost of airport services and G&A expense increased 4%. As mentioned earlier by Ricardo, throughout the year OMA took action to reduce overhead expenses particularly at the corporate level. The results during this quarter was a 32% reduction in minor maintenance and 18% decrease in materials and supplies, and a 2% reduction in subcontracted services. All these reductions were offset by an increase in payroll expense which will mainly because of severance payments incurred in the quarter as well as an adjustment to the retirement labor liability. Utilities also grew as a result of higher and appreciated tariffs which increased over 40% in the quarter. OMA's fourth quarter adjusted EBITDA increased 22% to MXN1.2 billion, and the adjusted EBITDA margin was 70%, up 238 basis points. As a result of all these factors, consolidated net income rose 31% to MXN819 million. Our cash flow generation from operations was also strong. Total cash from operating activities increased 26% to MXN3.7 billion in 2018. This principally reflects the strong operating performance of the Company. Before I open the call up for questions, let me reiterate the achievements for the quarter. Double-digit revenue growth based on steady growth in passenger traffic as a result of increased capacity in our main routes, sustained levels of adjusted EBITDA and adjusted EBITDA margin and solid cash flow generation with a strong cash flow financial position. This concludes our prepared remarks. Diego, please open the call for questions.
