Thank you, Jen. Good morning everyone. Thank you for standing by and welcome to OMA's first quarter 2020 earnings conference call. Ricardo Dueñas, Chief Executive Officer and Ruffo Pérez Pliego, Chief Financial Officer, will be joining us this morning and will discuss OMA's first quarter 2020 results.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 may be beyond our control, which include the impact of COVID-19.I will now turn the call over to Ricardo Duenas.
Ricardo Dueñas: Thank you, Emmanuel, and good morning to everyone and thank you for joining us today. I hope you and your families are healthy. Also on behalf of the entire OMA family I would like to share my deepest sympathy to all people around the world who have been effected by this pandemic and paying all those who have been working to keep off all of us safe during this difficult times.This morning I will review the evolution of our business during the current challenging scenarios caused by COVID-19 as well as our first quarter performance. In the second half of March the outbreak of COVID-19 began to generate an adverse impact in our operations.In order to counter the spread of the disease in March several countries including the United States and countries in Latin America announced flight restrictions and the closure of the wars for international travelers as well as containment measures of relation controls of their borders for international travelers as well as in some cases containment measures of their population.The Mexican government also implemented various measures to control this spread of COVID-19 including school closures and the suspension non-essential activities. On March 31, Mexico's Ministry of Health issued a decree suspending all non-essential activities in the country till April 30th. And then April 21st such suspension was extended till May 30th.Airport operations are considered an essential activity, so our airports have been remain operational. From April 1st to April 22nd, our total passenger traffic in our airports decreased 92% as compared to the same period of last year.We expect passenger traffic to increased a travel restrictions and stay at home ordinances are lifted. As up today, Mexico has not issued any restrictions on air travel. However, if the government issues restrictions to our operations or if current measures to counter the spread are extended, we may experience a significant additional decrease in our passenger traffic.Some of the companies airlines and other clients and tenants have asked for assistance. We are in commercial discussions with out clients in this respect. I would also like to mentioned that we have maintained a close and continuous communication with aeronautical and health authorities in order to protect our passengers on our personal working in our airports.We have implemented security and health measures such as sanitary filters, adaptation of isolation zones, use of infrared thermometers and antibacterial gel dispensers. We have reinforced our cleaning and disinfection processes and the use of mask for our employees among others.On the cost and expense side, we have started to implement cost reduction initiatives to mitigate the effect of the pandemic. Some of the measures we have implemented are, temporarily partial terminal closures, temporary reduction of subcontracted cleaning and security staff at the airports and the deferral of schedule minor maintenance work.This measures however will not be able to offset the impact of lower revenues as a results of the sharp decline in passenger traffic since the majority of our operation expenses are fixed. We cannot estimate the duration of the impact of this pandemic. Sorry, we cannot estimate duration of this pandemic and we'll have in the coming months on the volume of passenger traffic, the number of flight operations or our financial situation on the main airlines and commercial tenants that operate at our airports.As a result, we cannot estimate the impact of the material adverse effect on our results of operations or financial performance for 2020. It is worth noting the following; currently our cash position is similar to that of December 31st, 2019 and we maintained low leverage allowing us to meet our obligations.We have no significant debt maturities until June 2021 and we did not expect any difficulties in complying with our debt service or covenants. And even though our MDP works and progress are temporarily suspended, we do expect that COVID-19 pandemic to affect our committed investment in 2020 under the current master development programs.Finally, I would like to highlight that for liquidity preservation purposes in these uncertain times, our Board of Directors has recommended to declare the payment of a dividend at the upcoming shareholders meeting, which will be held on June 19.Conversely, the meeting will also vote on the cancellation of 3.7 million shares held in our treasury in favor of our shareholders. I invite all shareholders to respond to meetings call and attend or be represented at the meeting in June.Turning on our first quarter operational results. Total passenger traffic reached 4.9 million in the first quarter, down 5% compared to the first quarter of 2019. Since the second half of March, airline operating -- airlines operating in our airport have adjusted significantly their capacity offered and passenger traffic has decline accordingly.From March 1st through March 15, passenger traffic decline 2%, and for the remainder of the month it decline 61% compared to the same period in 2019. The routes that in first quarter of 2020 experienced the greatest impact on total passenger traffic due to their restrictions of frequencies or suspension of flights are; Monterrey on its Mexico City while Guadalajara and Cancun routes; Culiacan on its Tijuana route, and Acapulco on its Mexico city route. Overall, solid results in January and February were eclipsed by the traffic decline in March.As a result, adjusted EBITDA decreased 2.4% in the quarter and adjusted EBITDA margin reached 72.2% largely due to the decrease in aeronautical revenues which were partially offset by an increased in non- aeronautical revenues. On the commercial front, we implemented 21 initiatives in the quarter including car rental, retailers and restaurants among others.Commercial revenue grew 8.9% and the occupancy rate for commercial space in our terminals was 97% at the end of the quarter. Diversification activities delivered a revenue decreased of 4.8%, driven primarily by lower revenues from hotel services.During the first quarter of 2020, the occupancy rate of our terminal 2NH Collection Hotel and Hilton Garden Inn and Monterrey airport were 11.6 and 15.4 percentage points lower respectively than in the comparable period of 2019. Additionally, on April 6,we temporarily suspended services at the Hilton Garden Inn through at least April 30th due to low occupancy.Total investment in the quarter, including MDP investments, major maintenance and strategic investments were MXN220 million. Our major projects underway include the expansion and remodeling of Monterrey Airport Terminal A, expansion of Terminal C in Monterrey, expansion and remodeling of the Tampico terminal building, modernization of the Zihuatanejo terminal building, new passenger terminal building in Reynosa and work on runways, taxiways and aviation platforms in several airports.I would now like to turn the call over to Ruffo Pérez 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 the call for your questions. Turning to OMA's first quarter financial results.Aeronautical revenues decreased 3.6%, driven by the 4.9% decrease in passengers. Aeronautical revenue per passenger rose 1.3% in the quarter. Non-aeronautical revenues increased 3.4% with commercial revenues making the largest contribution to growth. Non-aeronautical revenue per passenger increased 8.7% in a quarter.Commercial revenues increased 8.9%. The best performing categories were restaurants, car rental and VIP lounges. Restaurants grew 23.1% due to the new spaces rented in Monterrey and Culiacán airport, as well as higher revenues derive from openings in previous quarters.Car rental revenues rose 15.1% as a result of the new contracts that have begun operations over the last quarters. VIP lounges grew 38.6% due primarily to the growth in the number of customers served during January and February. As a result, commercial revenues per passenger increased 14.5% to MXN46.7 as compared to the same quarter of last year.Diversification activities decreased 4.8%, mostly driven by hotel services. Total aeronautical and non-aeronautical revenues reached MXN 1.7 billion. Construction revenue decreased 6.0%. This is a 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 impact on earnings.The cost of airport services and G&A expense increased 0.6%. During this quarter payroll increased 6.7% mainly due to annual salary adjustments. This increase was offset by a lower cost in basic services as a consequence of lower cost of electricity. OMA's first quarter adjusted EBITDA decreased 2.4% to MXN1.2 billion, and the adjusted EBITDA margin was 72.2%, down 40 basis pointsDuring the quarter, our financing income was MXN289 million. We reported an exchange gain of 344 million, mainly as a result of our cash position nominated in U.S. dollars, which at the end of March, 2010 amounted to 80.0 million, primarily as a result of the aforementioned consolidated net income increased 27.6% to MXN970 million.Total cash from operating activities decline 33% to MXN375 million at the end of the quarter of 2020, mainly as a consequence of an increase in tax paid as compared to 1Q, 2019 and the reversal from net income of the FX gain since the FX gain is a non-cash item.This concludes our prepared remarks. Jen, please open the call for questions.
