Overview
Overview	Note 1 - Overview: Grupo Aeroportuario del Sureste, S. A. B. de C. V. (ASUR or the Company) is a Mexican company that was incorporated in April 1998 as a wholly-owned entity of the federal public government to administer, operate, maintain and exploit nine airports in the Southeast of Mexico. The nine airports are located in the following cities: Cancún, Cozumel, Mérida, Huatulco, Oaxaca, Veracruz, Villahermosa, Tapachula and Minatitlán. ASUR and its subsidiaries are collectively referred to as "the Company", "ASUR" or "the Group". The Company operates two companies that provide administrative services: Servicios Aeroportuarios del Sureste, S. A. and C. V. and RH Asur, S. A. de C. V. In addition, Aeropuerto de Cancún, S. A. de C. V. (Cancún Airport) has a more than 95% stake in the following subsidiaries: Caribbean Logistic, S. A. de C. V., Cargo RF, S. A. de C. V and Cancun Airport Services, S. A. de C. V., companies providing storage services, handling services, warehousing and custody of foreign trade merchandise and the related to the premises inspected at airports concessioned to third parties, as well as Cancun Airport Services, S. A. de C. V., whose main activity is to establish and operate shops, establishments and stores for the sale of all kinds of products. In June 1998, the Mexican Department of Communications and Transportation (SCT by its Spanish initials) granted to the Company’s subsidiaries concessions to administer, operate, exploit and develop the nine Southeast airports over a period of 50 years commencing on November 1, 1998. The term of the concessions may be extended by the parties under certain circumstances, in accordance with Article 15 of the Airports Law that establishes, among other things: 1) it had fulfilled the conditions set out in the respective title; 2) if requested before the five years of the concession’s validity begun, and 3) accept the new conditions. Notwithstanding the Company’s rights to administer, operate, exploit, develop and, if applicable, build the nine airports pursuant to the Mexican General Law of National Assets; all the land, furniture and permanent fixed assets located in the airports are the property of the Mexican federal government. Upon expiration of the Company’s concessions, these assets, including any improvements made during the term of the concessions, automatically revert to the Mexican federal government. Through its subsidiary Cancún Airport, on May 26, 2017, the Company increased its shareholding from 50% to 60% in Aerostar Airport Holding, LLC (Aerostar), which operates and manages Luis Muñoz Marín International Airport (LMM Airport) in San Juan, Puerto Rico. As a result of said increase, the Company acquired control of Aerostar, as it now has the capacity to direct its relevant business activities. With this acquisition, the company expects to continue offering world-class services to its clients and improving operations and client services for the benefit of passengers at LMM Airport. See Note 1.1. On October 19, 2017, the Company, through the Cancún Airport, acquired 92.42% of the shares of Sociedad Operadora de Aeropuertos Centro Norte, S. A. (Airplan), a company incorporated in Medellin, Colombia, on March 6, 2008 for the sole purpose of subscribing and executing the Concession Agreement for managing, operating, commercially exploiting, conditioning, modernizing and maintaining the Enrique Olaya Herrera in Medellín, José María Córdova in Rionegro, El Caraño in Quibdó, Los Garzones in Montería, Antonio Roldán Betancourt in Carepa and Las Brujas in Corozal airports. As of that date, Airplan consolidates its results into the Company’s financial statements. This acquisition is an important strategic addition that allows ASUR to penetrate the South American market by offering airport services at six airports in Colombia. See Note 1.2. On June 4, 2018, Remer Soluciones a la Inversión, S. A. de C. V. was merged into Consorcio Safij, S. A. de C. V. (with the latter as the surviving entity). On August 7, 2018, Consorcio Safij, S. A. de C. V. was merged into Compañía Inmobiliaria y de Inversiones del Noroeste, S. A. de C. V. (with the latter as the surviving entity). On October 15, 2018, Compañía Inmobiliaria y de Inversiones del Noroeste, S. A. de C. V. was merged into Inversiones Productivas Kierke, S. A. de C. V. (with the latter as the surviving entity) and currently holds 12.31% of the Company’s shares. On May 25, 2018, the Company, through the Cancún Airport, increased its shareholding in Airplan by acquiring an additional 7.58%, which gave it a 100% interest in that company. See Note 1.2. At December 31, 2019, the Company’s outstanding capital stock was held by the investing public (66.54)% and has been placed at securities markets in New York (NYSE) and Mexico (BMV), Inversiones y Technical Aeroportuarias, S. A. P. I. de C. V. (ITA) (7.65)%, CHPAF Holdings, S.A.P.I de C. V. (up to December 3, 2018, Servicios Estrategia Patrimonial, S. A. de C. V. and Agrupación Aeroportuaria Internacional III, S. A. de C. V.) (13.51)%, and Inversiones Productivas Kierke, S. A. de C. V. (up to June 4, 2018, Remer Soluciones a la Inversión, S. A. de C. V.) (12.31)%. Shareholding is divided amongst different shareholders, without there being an individual or a particular group that controls the Company directly. 1.1) Acquisition of Aerostar Until May 26, 2017, the Company considered Aerostar to be a joint venture (see Notes 1 and 9); as of June 1, 2017, in accordance with International Financial Reporting Standard 3, “Business combination”, the acquisition is considered a business combination. The following table summarizes the consideration pertaining to Aerostar at combination date or date of the transaction: May 30, 2017 Cash paid Ps. 726,628 Previous benefit acquired by departure of the previous shareholder 848,923 Consideration on May 26, 2017 1,575,551 Fair value of share capital held in Aerostar prior to the business combination 7,877,756 Non-controlling interest at the business combination date 6,302,205 Total purchase consideration Ps. 15,755,512 Due to the business combination, the following changes were effected: · The Company estimated a fair value of its previously acquired share capital in Aerostar of 50% at Ps.7,877,756, which showed a book value at the date of the transaction of Ps.2,353,040. As a result of measuring its interest in Aerostar at fair value, the Company has recognized a nonrecurring profit, unrelated to the cash flow, of Ps.5,524,716, which is included as “Gain in business combinations” in the consolidated statement of income. The mechanics to determine fair value were based on the use of two methods: a) discounted cash flows and b) implicit multiples (based on a sample of comparable public companies). The most relevant assumptions considered in the first method were the applied discount rate, the projected passenger traffic, and its growth rate and percentages of revenue growth, costs and expenses in the term of the concession; and for the second method, the multiples of income and profit before interest, taxes, amortizations and depreciations and adjustments applied to the net premium of control. · Once the joint venture between the Company and Highstar Capital IV (Highstar) was executed, both parties decided to review the income received and contributions made in order to adjust the price to be paid for the 10% acquired by the Company. As a result of the revision, the adjustment to the price was Ps.848,923 (included in the line “Gain in business combinations” of the income statement). The consideration paid at May 26, 2017, includes an amount paid in cash by the Company of Ps.726,628 plus the benefit previously acquired for the departure of Highstar. Additionally, as a result of the consolidation of Aerostar at the date of the business combination, the effects of foreign currency translation accrued at the transaction date were recycled, which amounted to Ps.655,515. This movement was recorded in the line “Gain in business combinations” within the consolidated statement of income. Said gain was presented as an adjacent line where the equity method was recognized, as it is considered associated with said transaction and because the Company does not perform this type of operations as part of its ordinary activities. · During the evaluation of assets stage, an intangible asset derived from the “commercial rights” acquired was identified, representing the rights to commercially exploit the areas of the airport in addition to the aeronautical operation, such as, commercial store leasing and advertising spots, etc., amounting to Ps.6,053,820. For its identification, the discounted cash flow method was used to determine the fair value of commercial rights, and the most relevant assumptions considered were the applied discount rate, projected passenger traffic, as well as percentages of revenue, costs and expenses growth during the term of the concession. · Due to the difference resulting from the comparison of the fair values and the book value, a deferred income tax (IT) was determined at Ps.605,382. · The difference between the net assets acquired in the business combination and the total consideration results in a goodwill of Ps.5,606,265 at the business combination date (see Note 8.1). The goodwill associated with this business combination is not deductible for IT purposes. · An amortization of the intangible identified in the business combination has been determined at Ps.98,780 and expensed as part of the depreciation and amortization in the consolidated statement of income. · The non-controlling interest derived from this transaction was determined to be Ps.6,302,205. This interest was determined at fair value with references to comparable market values, since Highstar at the same time sold its interest to another company at the time of the transaction. In the case of business combinations carried out in stages, International Financial Reporting Standards (IFRS) require that any interest previously held by an acquirer in the acquired entity be adjusted to its fair value at the business combination date, and any gain (or loss) arising from such remeasurement are recognized under gain or loss in the consolidated statement of income. The IFRS also require that any amount previously recognized in comprehensive income relating to such investments be recycled to the consolidated statement of income, as if such investment were sold. The fair value of the trade and accounts receivable considered in the business combinations approximate their carrying value. Liabilities at the fair value have been calculated at the date of the transaction and correspond mainly to bank loan valuations. At the reporting date, those liabilities were evaluated, and it has been determined that book value is the same as the fair value determined, which was calculated based on their possible settlement. The cash flow required to settle those liabilities is expected to materialize between 1 to 17 years. The liabilities have also been calculated at the fair value at the combination date and are similar to their book value. Following are the fair value of the net assets acquired under the business combination at the acquisition date: Fair value Assets CURRENT: Cash and cash equivalents Ps. 543,242 Restricted cash and cash equivalents 16,989 Other current assets 142,410 Current assets 702,641 NON-CURRENT: Land, furniture and equipment 135,929 Intangible assets, airport concessions - Net 19,308,402 Total non-current assets 19,444,331 Total assets Ps. 20,146,972 Liabilities CURRENT: Current liabilities Ps. 647,896 NON-CURRENT: Long-term debt 8,254,620 Deferred income tax 808,894 Other non-current liabilities 286,315 Total non-current liabilities 9,349,829 Total liabilities 9,997,725 Net assets acquired under the business combination 10,149,247 Total purchase consideration 15,755,512 Goodwill at the acquisition date (Note 8.1) Ps. (5,606,265) The main characteristics of fair value adjustments are described below: Caption Item Methodology Intangible assets: Commercial rights Commercial exploitation rights at the LMM Airport Discounted flows and implicit multiples using the WACC rate The fair value adjustments set forth in the previous table were obtained for the purpose of applying the purchase method of the Aerostar acquisition. The noncontrolling interest was recognized as its fair value. The projection used to apply the aforementioned methodologies was based on business plans approved by Aerostar management. The goodwill recognized by the Company is attributable to the expected growth in the North American airport sector and in line with the Company’s expansion opportunity in the consolidation of additional airport groups. No contingent liability or contingent consideration arrangement has arisen from this acquisition. If the acquisition had taken place on January 1, 2017, pro-forma revenues would have increased by Ps.1,549,099 (unaudited) and pro- forma net income by Ps.127,042 (unaudited). For the determination of the fair value of the noncontrolling interest, considering the absence of public market prices of Aerostar, the fair value of the controlling party was taken as a basis, which reflects a goodwill of the Company as a whole, including the controlling and noncontrolling parties, thereby better reflecting the economic interests of the transaction given that the noncontrolling party also participated in the future economic benefits generated from the acquisition. Aerostar relevant information and its significant non-controlling interest The Aerostar condensed financial information at December 31, 2018 and 2019, which shows its significant non-controlling interest, is shown below: Year ended December 31, 2018 2019 Condensed statement of financial position Cash and cash equivalents Ps. 868,095 Ps. 698,466 Restricted cash and cash equivalents 47,332 165,622 Other current assets 175,479 133,992 Total current assets 1,090,906 998,080 Financial liabilities: Current liabilities (640,785) (672,943) Working capital 450,121 325,137 Land, furniture and equipment 174,450 160,186 Intangible assets, airport concessions - Net 13,587,071 12,956,965 Other long-term assets 544 16,759 Long-term debt (7,282,269) (6,799,941) Accounts payable to the Company (1,152,805) (372,798) Other long-term liabilities (21,608) (19,783) Deferred income tax - Net (330,999) (371,984) Shareholders’ equity Ps. 5,424,505 Ps. 5,894,541 Year ended December 31, 2017 2018 2019 Condensed statements of comprehensive income Revenue Ps. 1,497,557 Ps. 3,025,267 Ps. 3,306,149 Operating cost and expenses (1,186,028) (2,098,323) (2,270,055) Other income 134,637 204,074 Comprehensive financial cost - Net (295,803) (538,268) (485,037) Deferred income tax (28,679) (62,252) (55,781) Net (loss) income for the year (12,953) 461,061 699,350 Foreign currency translation 254,110 (5,772) (229,314) Total comprehensive income for the year Ps. 241,157 Ps. 455,289 Ps. 470,036 Regarding the non-controlling interest in its subsidiary Aerostar, there are no significant restrictions on the possibility of having access to the assets or of using them for the payment of obligations. 1.2) Acquisition of Airplan 1) On October 19, 2017 (business combination date, or the transaction date), Cancún acquired 92.42% of the shares of Sociedad Operadora de Aeropuertos Centro Norte, S.A. (Airplan), a Company incorporated in Medellín, Colombia, on March 6, 2008, with the business purpose of managing, operating, commercially exploiting, conditioning, modernizing and maintaining the Enrique Olaya Herrera in Medellín, José María Córdova in Rionegro, El Caraño in Quibdó, Los Garzones in Montería, Antonio Roldán Betancourt in Carepa and Las Brujas in Corozal airports. At the transaction date, Airplan consolidated its results into the Company’s consolidated financial statements. A goodwill of Ps.1,474,955 was recognized at the business combination date (see Note 8.1). The goodwill associated with this business combination is not deductible for IT purposes. The fair value of the Trade and accounts receivable considered in the business combinations approximate their carrying value. The liabilities have been determined at fair value at the date of the combination and correspond mainly to the valuation of bank loans. For the determination of the fair value of the non-controlling interest, comparable market values were used (based on a sample of comparable public companies). The most relevant assumptions considered were multiples of income and earnings before interest, taxes, amortizations and depreciations and adjustments applied to the net premium of control. The following table summarizes the consideration pertaining to Airplan at the business combination date: October 19, 2017 Consideration paid on October 19, 2017 Ps. 3,789,797 Non-controlling interest at the combination date 310,827 Total purchase consideration Ps. 4,100,624 The distribution of the purchase price over the net assets acquired of Airplan at the business combination date are shown below: Fair value Assets CURRENT: Cash and cash equivalents Ps. 37,716 Other current assets 189,372 Current assets 227,088 NON-CURRENT: Land, furniture and equipment 3,400 Intangible assets, airport concessions - Net 7,232,588 Total non-current assets 7,235,988 Total assets Ps. 7,463,076 Liabilities CURRENT: Current liabilities Ps. 551,000 NON-CURRENT: Bank loans 3,424,897 Deferred income tax 861,483 Other non-current liabilities 27 Total non-current liabilities 4,286,407 Total liabilities 4,837,407 Net assets acquired under the business combination 2,625,669 Total consideration 4,100,624 Goodwill at acquisition date (Note 8.1) Ps. (1,474,955) The main characteristics of fair value adjustments are described below: Caption Item Methodology Intangible assets: Concession Commercial exploitation rights in Airplan Discounted flows and implicit multiples using the WACC rate Non-current liabilities: Long-term debt Fair value of the Bank loans Present value of estimated future cash flows The fair value adjustments specified in the previous table were obtained from Company management for the purpose of applying the purchase method to the acquisition of Airplan. The noncontrolling interest was recognized based on the proportional interest in net acquired assets. The projections used to apply the methodologies described above were based on the business plans approved by the administration of Airplan at the time of acquisition, which subsequently served as the basis for the analysis of deterioration made by the Administration at the date of the consolidated financial statements. The goodwill recognized by the Company represents non-separable assets due to the growth potential and development opportunities of Airplan. No contingent liability has arisen from this acquisition that must be registered; there are also no contingent consideration agreements. If the acquisition had taken place on January 1, 2017, pro-forma revenues would have increased by Ps.2,640,493 (unaudited) and pro-forma net income by Ps.231,130 (unaudited). 2) On May 25, 2018, the Company increased its shareholding in Airplan by acquiring an additional 7.58%, which gave it a 100% interest in that company. Considering and that on October 19, 2017, a record was made of the acquisition of businesses via the acquisition method established in IFRS 3 using fair value of the overall business determined at the date of acquisition, recording of the operation involving the additional acquisition resulted in recognition within stockholders’ equity of the net effect (definitive values) of the operation, which is analyzed as follows: May 25, 2018 Consideration paid for the non-controlling interest Ps. 213,469 Carrying value of the non-controlling interest (327,003) Difference recognized in stockholders’ equity Ps.

Revenue from Contracts with Cus

Revenue from Contracts with Customers:	12 Months Ended

Revenue from Contracts with Customers:
Revenue from Contracts with Customers:	Note 3 - Revenue from Contracts with Customers: The Company adopted IFRS 15 “Revenue from contracts with customers” starting on January 1, 2018. IFRS 15 specifies how and when to recognize income, in accordance with a 5-step model based on principles applied to all contracts with customers. In step 1, contracts with clients are identified. In step 2, performance obligations for each of the contracts are identified. In step 3, transaction prices are determined. In step 4, transaction prices are assigned to individual performance obligations. In step 5, the respective income is recorded when the company has complied with all performance obligations pertaining to each contract, the condition for which is that control of services has been transferred to the client. After analysis of the contract under IFRS 15, the Company determines whether income arising from each contract should be recognized at a particular point in time or over time. That determination is based on specific criteria related to the point at which each performance obligation is transferred to the client. The Company uses the simplified retrospective transition method, which resulted in changes to accounting policies and in a breakdown of performance obligations in the note on segments in the consolidated financial statements. The simplified retrospective transition method does not alter the information presented at the close of the preceding period. Other IFRS 15 implications are described in the following portion of this note. 3.1) Revenue recognition Airports operated by the Company receive income from external clients for aeronautical services rendered to airlines and from rendering complementary services. The Company also recognizes income from construction services arising from concession agreements with government entities. IFRS 15 provides practical expedients that allow entities to ignore the effects of a financing component in certain circumstances. In cases where goods or services are provided, the practical expedients focus on the point at which payment is made rather than the duration of the contract. The practical expedients can be used even when the duration of the contract exceeds 12 months, provided the time difference between the performance obligations thereto and receipt of payment is less than 12 months. However, the practical expedients cannot be used to ignore the effects of financing in the first 12 months of a longer - term agreement that includes a significant financing component. The Company has opted to make use of these practical expedients for its agreements that exceed 12 months in length where the deadline for complying with its performance obligations thereto and receipt of payment is less than 12 months. Following is a description of the principal types of service agreements from which the Company receives income. 3.1.1) Aeronautical services The Company operates airports in three countries (Mexico, Puerto Rico and Colombia), providing different aeronautical services involving principally the following performance obligations. a. Passenger fee rates (Airport Use Rate - TUA), which are calculated based on total outgoing passengers (other than diplomats, infants and passengers in transit) making use of air terminals operated by the Company. b. Landing rates, which contemplate landing services, the use of runways, taxiing strips, and bands. c. Platform use fees, based on the time an aircraft remains at a terminal after landing. d. Security, calculated on the basis of the total number of incoming and outgoing passengers. e. Baggage inspection fee, calculated on the basis of total number of outgoing passengers. f. Use of passenger walkways, which consists of rendering passenger walkways service connecting an aircraft to the terminal after landing. g. Fee for the use of passenger documentation counters; the fee is applied on the basis of the holding of documentation for one-hour periods. After the first hour has elapsed, the fee is charged proportionately for 30‑minute increments. Revenue is measured based on the consideration specified in the tariff regulating system applicable to airports in each country for each performance obligation identified. In Mexico, these are regulated by the Secretariat of Communications and Transport (SCT), in Puerto Rico by the Federal Aviation Administration (FAA) and in Colombia by Aerocivil. Passenger, landing and security rates are recorded at a particular point in time, once the aircraft departure manifest has been delivered. Income arising from other performance obligations is recorded over time as the services are rendered. Discounts The Company may apply discounts to its rates, provided they are not discriminatory in the light of the laws in effect in the countries in which the Company operates. Discounts are granted based on the discount policy and conditions negotiated with the National Autotransportation Chamber (CANAERO), and regulated income must be delivered within a period of 30 days. Revenue is recorded net of estimated discounts based on applicable rates. The prompt-payment discount for regulated income principally the Airport Use Fees (TUA by its initials in Spanish) is established in each of the contracts signed with the airlines, and is subtracted from the aforementioned income. In 2017, 2018 and 2019, the discount amounted to Ps.43,802, Ps.45,293 and Ps.47,374, respectively. There is no balance for the contractual liability for that item. Terms of payment According to the airport service contract signed with clients, the credit term is 30 days; and the first of each month for complementary services. 3.1.2) Non-aeronautical services The Company generates income from non-aeronautical services, which involve basically the following performance obligations: a. Access rates to nonpermanent overland transportation based on the number of access events experienced by the transportation companies operated by third parties providing passenger transportation services at the terminal. b. Carparks, rates based on the time vehicles remain at public parking areas. c. Retail sales, recorded when a product is sold to a client and payment on the transaction is made at the time of purchase. Revenue arising from access rates to overland transportation and retail sales are recorded at a particular point in time, to the extent that the performance obligation is satisfied and the promised goods and services are transferred, while parking area income is recorded over time. Contracts for commercial income IFRS 15 must be applied to all contracts with clients. However, there are exceptions, such as contracts for the leasing of commercial space, which fall under IFRS 16 “Leases”. Leasing income (non-regulated activities) are considered complementary services to the supply of regulated services so there is no separate infrastructure other than the intangible recognized under Note 8, nor is a right of use to be accounted for separately in the adoption of IFRS 16. Presently, space leased at airports to airlines and other commercial lessees comprise the most significant source of income related to non-aeronautic services. Leasing income is accrued monthly and is determined by applying a percentage established in the lease contract to income from actual sales of lessees (interest), or an agreed minimum fee. Commercial leasing operations include the leasing of automobiles, the sale of food and beverages, retail sales, sales made at kiosks, graphic advertising, overland transportation, fixed operations and other services rendered. Commercial income is partially recorded on the basis of lessee income and is partially based on minimum lease rates. Leasing income is accrued monthly and is determined by applying a percentage established in the lease contract to income from actual sales of lessees (interest), or as an agreed minimum fee. At December 31, 2017, 2018 and 2019 , variable leasing income was Ps.2,446,980, Ps.3,371,634 and Ps.3,435,382, respectively, and Ps.166,747, Ps.750,075 and Ps.830,287, respectively, for fixed leasing rates. 3.1.3) Construction services As an operator of airport concessions, the Company is required to improve items under concession. Works carried out within the airport are based on development plans authorized by the regulators. Income from construction services are recognized in accordance with the methods prescribed (input method) for measuring progress towards completion approved by the grantor. Improvements made are expected to complement the infrastructure of the airport operated by the Group. IFRS 15 establishes that during the construction period of the infrastructure related to concessions received, they must be shown as “contract assets” in the statement of financial position, regardless of the type of consideration received (financial asset or intangible asset). See Note 8. Construction services carried out by the Group do not entitle it to a direct cash consideration; rather, it is entitled to charge users for airport services rendered at the terminals during the concession period. Income from construction services is measured at fair value of the services rendered, which increased the value of the intangible asset, plus the cost of capitalizable financing.

These are the works that the concessionaire undertakes to execute in compliance with the Airport Adjustment and Modernization Plan. (ii) Complementary works. These are the works that are not part of the Adequacy and Modernization Plan but are executed at the proposal of the concessionaire, or at the request of the grantors. As of December 31, 2017, 2018 and 2019, revenues from construction services in Mexico were Ps.1,580,997, Ps.263,395 and Ps.725,047 and in Puerto Rico they were Ps.75,925, Ps.360,004 and Ps.335,148, respectively. 3.1.4) Airports Law and Regulations Mexico Under the Airports Law and regulations thereto, company income is classified as Airport Services, Complementary Airport Services and Commercial Services. Airport Services mainly consist of the use of runways, taxiways and platforms for landings and departures, parking for aircrafts, use of mechanical boarders, security services, hangars, car parking, as well as the general use of the terminals and other infrastructure by the aircrafts, passengers and cargo, including the rental of space that is essential for the operation of airlines and suppliers of complementary services. Complementary Services consist mainly of ramp services and handling of luggage and cargo, food services, maintenance and repair and related activities that provide support to the airlines. Revenues from access fees charged to third parties that provide complementary services are classified as Airport Services. The Rate Regulation Law provides that the following sources of revenues are regulated under this system: · Revenues from airport services (as defined under the Mexican Airport Law), other than automobile parking, and · Access fees earned from third parties providing complementary services, other than those related to the establishment of administrative quarters that the SCT determines to be non-essential. Non-regulated Services consist of services that are not considered essential for an airport's operation, such as the rental of spaces to businesses, restaurants and banks. Access fees and income from other services are recognized as services are rendered. The following table sets forth Company revenue at December 31, 2017, 2018, and 2019 using the classification established in the Airport Law and the Regulations thereto. The grouping for the 2018 and 2019 periods was considered on the basis of performance obligations established under IFRS 15, whose difference as compared to 2017 grouping consist of showing the Company’s own retail sales which were Ps.621,850, under unregulated services with income arising from contract with clients.

Accounts receivable are comprised mainly of TUA paid by passengers (other than diplomats, infants and passengers in transit) who travel using the airport terminals operated by the Company. The balance at December 31, 2018 and 2019 amounted to Ps.600,518 and Ps.615,223, respectively. At December 31, 2019, the total balance of unimpaired past due accounts receivable was Ps.580,914 (Ps.424,262 at December 31, 2018). These accounts relate to a number of independent clients that do not have a recent history of non-compliance. The movements in the impairment provision are as follows: Provision for impairment at January 1, 2018 Ps. 173,398 Application to the provision in Mexico during the period (35,403) Aerostar’s provision impairment 20,128 Airplan’s provision impairment 3,232 Valuation IFRS 9 provision 18,284 Provision for impairment at December 31,2018 179,639 Application, net of Mexico's estimate during the period (369) Application, net of Aerostar's estimate during the period (5,585) Airplan's provision impairment 18,081 Provision for impairment at December 31,2019 Ps. 191,766 Provision for impairment of accounts receivable has been recorded in the consolidated comprehensive income statement under cost of services, and the amounts charged to the provision are written off from accounts receivable when recovery is not expected. From January 1, 2018, the Company applies the simplified approach contained in IFRS 9 for measuring expected credit losses, which makes use of an expected loss provision over the lifetime of the instrument for all accounts receivable and contract assets. In order to measure expected credit losses, accounts receivable and contract assets have been grouped on the basis of their shared credit risk features and days past due. The Company held no relevant contract assets at January 1 or December 31, 2018 and 2019. The expected loss rates are based on the profiles for payment of sales in a 12‑month period prior to December 31, 2018 and 2019 or January 1, 2018 and 2019, respectively, and on historical credit losses experienced within that period. Historical loss rates are adjusted to reflect current and prospective information on macroeconomic factors affecting client capacity for covering accounts receivable. The Group has determined that the economic situation of a country can have adverse effects on the transportation industry, in addition to the cost of complying with aviation regulations and union pressures on airlines, which are the most relevant factors, and therefore adjusts historical loss rates based on changes expected in those factors. On that basis, the provision for losses at December 31, 2018 and at December 31, 2019 was determined as follows for accounts receivable and for contract assets: More than Due to expire 1 to 90 91 to 180 181 to 365 365 Expected loss rate: Mexico 0.02 % 0.02 % 0.02 % 100 % 100 % Aerostar 1.00 % 2.5% - 5.0 % 15.00 % 50 % 100 % Airplan 0.83 % 0.83 % 0.83 % 100 % 100 % Moren Total estimate Due to expire 1 to 90 91 to 180 181 to 365 than 365 12/31/2018 At December 31, 2018 Mexico’s accounts receivables Ps. 93 Ps. 604 Ps. 1,252 Ps. 495 Ps. 128,804 Ps. 131,248 Mexico’s provision impairment 495 128,804 129,299 Aerostar’s accounts receivables 154,235 49,645 239 5,790 36,738 246,647 Aerostar’s provision impairment 386 124 36 5,790 36,738 43,074 Airplan’s accounts receivables 183,223 5,653 188,876 Airplan’s provision impairment 1,613 5,653 7,266 Total estimate Ps. 386 Ps. 1,737 Ps. 36 Ps. 11,938 Ps. 165,542 Ps. 179,639 More Total estimate Due to expire 1 to 90 91 to 180 181 to 365 than 365 12/31/2019 At December 31, 2019 Mexico’s accounts receivables — Ps. 1,012 Ps. 1,733 Ps. 126 Ps. 128,930 Ps. 131,801 Mexico’s provision impairment 128,930 128,930 Aerostar’s account receivables Ps. 159,796 97,697 2,176 712 31,236 291,617 Aerostar’s provision impairment 1,599 3,611 544 499 31,236 37,489 Airplan’s accounts receivables 114,858 52,410 15,357 8,602 191,227 Airplan’s provision impairment 953 435 15,357 8,602 25,347 Total estimate Ps. 1,599 Ps. 4,564 Ps. 979 Ps. 15,856 Ps. 168,768 Ps. 191,766

The depreciation expense for 2019 for the right-of-use assets for consolidated leasing was Ps.6,653 in Mexico, there was no recognition of right-of-use assets for leasing in Aerostar and Airplan. 7.1) As from January 1, 2019, some leases are recognized as right-of-use assets and lease liabilities on the date the leased assets are available for use by the Company by adopting a simplified approach, whereby no significant comparative information is restated. Therefore, reclassifications and adjustments derived from new lease standards are recognized in the Statement of Financial Position at January 1, 2019. The new accounting policies are disclosed in Note 18.8. Following the adoption of IFRS 16, the Company recognized lease liabilities for the leases previously classified as "operating leases" under IAS 17 "Leases". Lease liabilities were measured at the present value of remaining lease payments, discounted at the interest rate of the lessee at January 1, 2019. The weighted average interest rates of the lessee applied to lease liabilities at January 1, 2019 were 9.04%. Practical expedients used: For IFRS 16 first-time adoption, the Company has used the following practical expedients allowed by this standard: - - The Company has also opted not to apply any restatement if a contract is, or contains, a lease at initial implementation. For contracts executed before the transition date, the Company relied on the assessment made under IAS 17 and IFRIC 4 "Determining whether an arrangement contains a lease". Due to the adoption of the new standard, the main impacts as of December 31, 2019 amount to approximately Ps.20,422 which is not significant. Right-of-use assets associated with property leases were measured retrospectively, as if the new standards had always been applied. The Company has executed a contract for the lease of corporate offices and commercial vehicles which were recognized as right-of-use assets and are incorporated into Land, furniture and equipment, Net. The general terms of the lease contracts are shown below: Corporate offices in Mexico: Separate contracts govern our corporate offices in Mexico. These contracts include the following terms and conditions: i) 5-year term; ii) monthly lease payments of USD23,194 (Ps.437 thousand approximately); iii) a security deposit equivalent to 2-months' rent; iv) the monthly base rent will be increased annually after the first year of the contract, in line with the increase in the U.S. Consumer Price Index; and v) in the event of nonpayment of principal, default interest will accrue at the most recent interest rate in U.S. dollars published by the Wall Street Journal, the prime rate plus ten basis points. Lease of commercial vehicles in Mexico: A framework contract, governs our lease of commercial vehicles in Mexico, with separate contracts by vehicle, which includes the following terms and conditions: i) minimum term of 48 months; ii) monthly fixed payments and an extraordinary one-off rent payable in the first month; iii) cash value to be settled at the end of the minimum term; iv) the lessee shall have a preferential right to acquire the underlying assets at the end of the contractual term; and) in the event of nonpayment of lease payments, default interest shall accrue at a monthly rate of 3%. The lease and services contracts for which lease assets were identified in accordance with IFRS 16 Leases at the Aerostar and Airplan subsidiaries are not significant. The lease agreements and service contracts for which lease assets were identified in accordance with IFRS 16 were not significant for the Company. See Note 18.1.

Goodwill is assigned to the operating segments that are expected to benefit from the synergies of the business combination, regardless of whether other assets or liabilities of the acquired entities are assigned. The following is a summary of the allocation of goodwill for each operating segment: December 31, 2018 and 2019 Aerostar Ps. 1,057,651 Airplan 1,509,714 Ps. 2,567,365 Significant estimate - Impairment: As a result of the passage of Hurricane Maria on the island of Puerto Rico on September 20, 2017, which affected the infrastructure of the LMM Airport as well as causing severe damage to the rest of the island that impacted the expected future flows of Aerostar, the Company recognized an impairment of Ps.4,719,096 in cost of aeronautical and non-aeronautical services within operating costs and expenses. As a result of the above, the Administration also carried out impairment tests on the intangible asset of the concession, without determining a deterioration to be recognized. Remaining a net effect, as shown below: Goodwill (Note 1.1) Ps. 5,606,265 Impairment (Note 4) (4,719,096) Ps. 887,169 Methodology: Aerostar and Airplan.- The Company's management performed the calculation based on the fair value less costs to sell and the value in use, in accordance with the methodologies established in IAS 36. The carrying amount of the cash generating unit was compared to its recoverable amount. The recoverable amount is determined as the higher of the fair value of the cash generating unit and its value in use. In this case, the Company’s management chose the value in use of the cash generating unit which was determined using discounted cash flows. For the determination of value in use, projections of cash flows approved by the Administration are used, covering a period of 33 years in the case of Aerostar and 12 years in the case of Airplan, which are the remaining years of the airport concessions. For each CGU with a significant amount of goodwill, the key assumptions are the following: 2018 2019 Airplan Aerostar Airplan Aerostar Discount rate for the value in use method 10.46 % 10.93 % 9.66 % 9.60 % Annual average of revenue, operating costs and expense growth rate 3.10 % 4.14 % 5.25 % 4.45 % Output passenger growth rate 4.50 % 2.50 % 6.70 % 2.50 % Level of the fair value hierarchy of value recoverable from the CGU 3 3 3 3 Management has determined the values assigned to each of the above key assumptions as follows: Assumptions Approach used to determine the values Discount rate It reflects the specific risks related to the market rates of the industry and the countries in which they operate. Annual average of revenue, operating costs and expense growth rate Weighted average growth rate during the period of the concessions, historical trends of national and international passengers are based. Passenger departures growth Weighted average rate of growth in departing passengers rates during the period of the concessions which is linked to the operational and financial growths. CGU Aerostar: 2018: If the discount rate applied to the cash flow projections of this CGU would have been + 1% or -1%, management’s estimate would have to recognize additional effects. In the case of a rate increase (11.93% instead of 10.93%), the Company would have to recognize an additional impairment of Ps.617,025, and in the case of the decrease in the rate (9.93% instead of 10.93%) the excess of cash flows against the carrying value would be increased by Ps.2,350,705. 2019: If the discount rate applied to the cash flow projections of this CGU had been + 1% or -1% (instead of 9.60)%, management's estimate would have had the following effects: an excess of cash flows against the carrying amount of Ps.3,937,096 and Ps.9,876,930. CGU Airplan: 2018: If the discount rate applied to the cash flow projections of this CGU would have been + 1% or -1%, management's estimate would have to recognize the following additional effects. In the case of a rate increase (11.46% instead of 10.46%), the Company would have to recognize and additional impairment of Ps.118.552, and in the case of the decrease in the rate (9.46% instead of 10.46%) the excess of cash flows against the carrying value would be increased by Ps.371,769. 2019: If the discount rate applied to the cash flow projections of this CGU had been + 1% or -1% (instead of 9.66%), management's estimate would have had the following effects, an excess of the flows of cash against the carrying amount of Ps.615,993 and Ps.1,102,280, respectively. 8.2) Basic terms and conditions of the concessions Mexico: The basic terms and conditions of each concession are the following: a) The concession holder must undertake the construction, improvement and maintenance of the facilities in accordance with its Master Development Plan (MDP) and is required to update the plan every five years.

Aerostar: The purpose of the Aerostar concession (Agreement) is to operate the public airport safely by maintaining the highest possible levels of safety and protection at the LMM Airport, and promoting, facilitating and improving commerce, tourism and economic development. The Puerto Rico authorities, Aerostar and the other airlines have agreed to the terms and conditions of the LMM Airport Facility Contract. The concession period is 40 years as of the closing of the agreement assigning the Airport’s operating rights (February 27, 2013). Under the Agreement, Aerostar has no rights to control in full the use of the Airport facilities, for example, airport facilities that are under the supervision of the Authority or internal or external security in certain areas and it is required to provide certain maintenance services within the airport. As part of the Agreement, the authorities granted Aerostar the right to sublease the LMM Airport non-aeronautical areas and to collect and retain the fees, charges and payments and income arising from all subleased facilities. According to the provisions of the Agreement, the Company has the right to collect the annual contributions of all airlines, which will be equal to the sum of the: a) platform use fees; b) landing fees; c) other leases, and d) international and domestic airport use fees. The Agreement requires Aerostar to make a cash payment of USD 2.5 million per year for the first five years after the first five years, the authority establishes a payment of “Annual Authority Income Share”, consisting of 5 % of the gross revenues of the airport obtained by Aerostar from the sixth year to the thirtieth year. From year 31 to 40, this amount will increase to 10% of the airport’s gross revenues. Airplan: The object of the concession contract 8000011-0K is the granting by the Special Administrative Unit of Civil Aeronautics of Colombia in favor of Airplan of a concession for the administration, operation, commercial exploitation, adaptation, modernization and maintenance of the airports Antonio Roldán Betancourt, El Caraño, José María Córdova, Las Brujas and Los Garzones, and the granting by Enrique Olaya Herrera Airport - AIH in favor of the concessionaire of the concession for the administration, commercial operation, adaptation, modernization and maintenance of Enrique Olaya Herrera Airport. The term of execution of the contract extends from the date of signing of the act of commencement of execution and until the date on which one of any of the following events occurs: • • • It must be taken into account, for purposes of the regulated revenue expected as defined in the concession contract, that the expected regulated revenue will increase once each of the complementary works (mandatory or voluntary) is delivered to the grantor. The grantors agree to assign the regulated and unregulated revenues corresponding to each of the airports to Airplan. The concessionaire will obtain all of its remuneration for the concession from the assignment of the regulated revenues and the unregulated revenues that the grantors make in their favor. The concessionaire is obliged, with the grantor to pay, during the term of the contract, a consideration equivalent to 19% of the gross income of the concessionaire. The concession granted by virtue of this contract imposes on the concessionaire the general obligation to administer, make commercial use and operate the airports in accordance with the minimum specifications set forth in the contract and at their own risk. The determination of the economic useful life of the intangible asset is subject to the percentage of execution of the revenues with respect to the total expected income in the Company's financial model. Fiduciaria Bancolombia Contract: In accordance with the requirements of the concession agreement, on June 25, 2008, Airplan constituted a trust and entered into a trust agreement with Fiduciaria Bancolombia making that institution the trustee. The trust was constituted to administer the concession’s resources and to oversee the payment of the concession’s obligations by the concessionaire. Airplan transfers all of the gross income it receives and all of the debt and capital resources it obtains from the administration of the concession to the trust. The trustee maintains, in accordance with current accounting standards, a record of each and every one of the payments and transfers that are made to third parties or to the concessionaire itself, making the appropriate charges to the trust’s accounts. The foregoing is without prejudice to the assignment of regulated revenues and non-regulated revenues to the concessionaire and not the trust. The debt and capital resources obtained by the concessionaire are recorded in the concessionaire’s own accounts and only kept for record purposes in the trust because the trust is constituted for purposes of administering such resources. The constitution of the trust was made through the execution of an irrevocable mercantile trust and administration contract whose term is the maximum term authorized by the Colombian Commercial Code. 8.3) Subsequent measurement of the intangible asset The Company will subsequently measure the intangible asset over its economic useful life at cost, less accumulated amortization and impairment loss.

Investment in joint ventures accounted for under the equity method:	Note 9 - Investment in joint ventures accounted for under the equity method: In 2013, the Company participated in a bidding process through its subsidiary, Aeropuerto de Cancún, S. A. de C. V. (Cancún Airport) for a long-term lease agreement to operate and administer the LMM Airport located in San Juan, Puerto Rico. The investment between Highstar Capital IV (Highstar) and Cancún, created Aerostar Airport Holdings, LLC (Aerostar). It was determined that operations of Aerostar constitute a joint venture. Aerostar signed a 40‑year lease agreement to operate the LMM Airport. As part of the bidding terms, Aerostar made an initial payment of USD615 million (PS. 7,846 million pesos approximately) to the Puerto Rico authorities. A portion of that payment was funded by a private placement of bonds by Aerostar in the amount of USD350 million (PS. 4,471 million pesos approximately) in the same year of acquisition of the concession. Nature of the investment Aerostar is a limited liability company incorporated under the laws of Puerto Rico. It is mainly engaged in operating the facilities of the LMM Airport. Cancún Airport holds 60% in the ownership interest of Aerostar (50% until May 30, 2017) and the Public Sector Pension Investment Board “PSP Investments” owns the other 40% (until May 26, 2017, Highstar Capital IV held a 50% stake in Aerostar). See Note 1. Passenger Facility Charges (PFC) The United States Congress of North America approved the “Aviation Safety and Capacity Expansion Act.” In which it authorizes United States airports to impose a Passenger Facility Charge (PFC). PFC can be used for airport projects that meet at least one of the following criteria: preserve or improve the security, protection or capacity of the national air transport system; reduce noise or mitigate noise resulting from an airport; or provide opportunities for increased competition between airlines. PFC revenues and accrued interest are restricted for use in capital projects approved by the FAA and are classified as restricted cash. See Note 5.1. For the period from June 1 to December 31, 2017, the years ended December 31, 2018 and 2019, revenues collected by PFC were Ps. 191,356, Ps. 329,532 and Ps. 393,288, respectively. PFC are presented under "Aeronautical services" in the consolidated statement of comprehensive income. As of June 1, 2017, Aerostar consolidates its shareholding as a subsidiary in the Company, increasing its shareholding from 50% to 60%, for which the recognition as a joint venture is until May 26, 2017.

Income tax incurred and deferred:
Income tax incurred and deferred:	Note 14 - Income tax incurred and deferred: The Company does not consolidate its results for tax purposes. a. Income Tax (IT) Mexico: In 2017, 2018 and 2019, the Company determined tax profits in its subsidiaries in the amounts of Ps.6,358,687, Ps.5,984,043 and Ps.6,119,361, respectively. In 2019 and 2018, the tax profits were partially offset with the amortization of tax losses in the amounts of Ps.93,975, Ps.41,977 and Ps.36,613, respectively. The subsidiaries that at December 31, 2017, 2018 and 2019, have not assessed IT due to the tax loss carryforwards, are Cozumel, Minatitlán and Tapachula. Taxable income differs from the book income due to temporary and permanent differences arising from the different bases for the recognition of the effects of inflation for tax purposes and from the permanent effects of items affecting only the book or tax results. The ITL establishes for 2014 and subsequent years an income tax rate of 30%. The Company has performed the evaluation of the Preferential Tax Regimes and has determined that this year it is not applicable because it does carry out a business activity, in the case of the investment in the airport of Puerto Rico, and that passive income does not represent more than 20% of its total income. Aerostar: The Company determined tax loss for Ps.343,534 and tax profit for Ps.42,770 in 2018 and 2019 respectively, derived from the agreement with the Department of the Treasury of Puerto Rico in which its operations are subject to income taxes of Puerto Rico of 10% under the provisions of Section 12 (a) of the Public Private Partnership Law (Law) enacted in June 2009. Derived from the analysis carried out by the Administration, it is considered that there are no impacts due to changes in the legislation of the United States of America made since the 2018 fiscal year. Airplan: The Company determined taxable income in accordance with the tax law of Colombia for the period at December 31, 2018 and 2019 of Ps.94,843 and Ps.325,349, and a presumptive income on liquid equity, which results from applying the 4.0% 3.5% on the fiscal liquid equity of the previous year of Ps.23,462 and Ps.24,719, respectively. The Company is subject to income taxes in Colombia of 34% in 2017 and 33% for 2018 and 2019 plus a 6% surcharge on liquid income less COP.800,000 in 2018. The company determined an income tax of Ps.16,618 in 2017, Ps.31,298 in 2018 and Ps.107,365 in 2019 respectively, and an additional surcharge tax until December 31, 2018. Law 1739 of December 23, 2014 in force, establishes the determination and payment of a surcharge on income tax for equity - CREE, which is the responsibility of the taxpayers of this tax and applies to a taxable base higher than the COP.800,000, which is equivalent to 6%. That over rate was repealed to from the year 2018. Tax Reform Law No. 1943, dated December 28, 2018, sets forth the following rates applicable to corporate taxable income: 33% for fiscal years 2018 and 2019, 32% for fiscal year 2020, 31% for fiscal year 2021, and 30% as from fiscal year 2022.Over the fiscal taxable income.

This agreement includes an available extension of 60 months. The monthly rent due is USD23,194 (Ps.437 thousand pesos approximately). The total minimum future payments derived from the non-cancellable operating lease agreement that shall be covered in the future are as follows: Up to one year Ps. 5,250 Between one and three years 12,251 Total Ps. 17,501 At December 31, 2018, the rent expense embedded within the aeronautical and non-aeronautical service cost in the statement of income, was approximately of Ps.5,232. b. On June 22, 2018, the Company received SCT approval for the MDP for the five-year period from 2019 to 2023 in which the Company committed to carry out improvements. At December 31, 2019, investment commitments for that MDP are as follows: Period Amount 2020 Ps. 5,105,804 2021 3,015,346 2022 1,815,769 2023 849,295 Ps. 10,786,214 (1) (1) Figures in thousand pesos adjusted at December 31, 2019 based on the Construction Price Index (IPCO) in the terms of the MDP. c. Pursuant to the terms for the purchase of the land in Huatulco that occurred in October 2008, the Company has the obligation to build 450 hotel rooms, for which purpose the Company will enter into agreements with third parties to develop the comprehensive tourism plan without a specific due date. At December 31, 2019, there is an indefinite extension to this commitment issued by the National Tourism Fund (FONATUR by its initials in Spanish). d. As part of the Concession Agreement, Aerostar has committed to fund and complete certain capital and repair projects with respect to the LMM Airport Facilities. The Company has no time restrictions to complete these projects, except that they must be made at any time during the term of the lease. As these projects are carried out, repairs will be recorded as expenses incurred or capitalized and depreciated according to their nature; consistent with the Company's accounting policies. Capital projects will be capitalized as part of an intangible concession improvement asset and will be amortized over their useful lives or the remaining life of the concession contract, whichever is less. Some commitments were excluded from the liability for initial obligations assumed due to factors of uncertainty, the variability of future costs and the extended period of time in which commitments can be fulfilled. As of December 31, 2018 and 2019, Aerostar fulfilled the agreed commitments. e. On September 20, 2017, Hurricane Maria made landfall on the island of Puerto Rico. Operations were suspended at the LMM Airport on the 19th and resumed in a limited manner on the 21st of the month. The damages to airport infrastructure have been evaluated by the Company to be approximately USD29.7 million approximately, of which most have been disbursed at the reporting date and which amount will be recorded in the cost of services as incurred. The infrastructure has material damage insurance. During the 2018 and 2019 fiscal years, insurance recovery was obtained for USD10.0 and USD15.7 million, approximately Ps.196,512 and Ps.289,822 thousand, respectively, which are recognized in the comprehensive statement of income as the certification is obtained that the funds were used for the defined purposes and the indicated works. During 2018 and 2019, Ps.134,637 and Ps.204,719 were recognized as other income. As of December 31, 2019, there is USD7,358, approximately (Ps.138,773) in restricted cash, which will be recognized in the statement of comprehensive income as other income once the work certification is obtained by the insurer. See note. 5.1. f. Under the Plan for the Refurbishment and Modernization of the Airplan Concession Contract, the concessionaire is currently committed to delivering the work known as “Plataforma, Calle de Conexión y Bodegas del Terminal de Carga del Aeropuerto José María Córdova de Rionegro” (Platform, Connection Road and Cargo Terminal Warehouse at the José María Córdova Airport in Rionegro), which as agreed by the parties in Amendment No. 18 of the Concession Contract, should have been delivered on December 15, 2018. A time extension was therefore requested for delivery of that work, which was granted via an amendment to the Concession Contract under Amendment No. 23 which extends the term for delivery of that work by 18 months as from December 15, 2018. As of December 31, 2019, the work was still under construction. The work has since been completed. g. As it concerns complementary works, in addition to those specified in the Airplan Concession Contract (via Amendment No. 8 dated 2014), a conclusion is still pending the construction of the modules connecting the terminal building with the parking lot and José María Córdova flight works pertaining to one of the connection modules known as Point B. Due to technical difficulties, an order for suspension was issued and a new design was determined. Via amendment No. 22 to the concession contract dated April 4, 2018, the term for those works was extended by 541 days from April 4, 2018. As of December 31, 2019, the project has been completed. Contingencies As of December 31, 2018 and 2019, the Company has confirmed that the results of its lawsuits cannot be accurately predicted as their due processes are currently ongoing and there are not enough elements to determine whether they could largely affect the Company’s financial position in the case of an adverse ruling. h. i. j. k. l.

As of May 26, 2017, the Cancún Airport acquired an additional 10% equity interest in Aerostar, As a result of this acquisition, the Company has a 60% shareholding and now controls Aerostar, therefore Aerostar is consolidated in the Company’s financial statements. (**) Cancún Airport, S. A. de C. V. acquired on October 19, 2017 a 92.42% and later in May 25, 2018 the 7.58% left to obtain the 100% equity interest in Sociedad Operadora de Aeropuertos Centro Norte, S. A. (Airplan), Company that holds the concession for the administration, operation, commercial exploitation, adaptation, modernization and maintenance of the Enrique Olaya Herrera in Medellín, José María Córdova in Rionegro, El Caraño in Quibdó, Los Garzones in Montería, Antonio Roldán Betancourt in Carepa and Las Brujas in Corozal airports, and from that date, Airplan’s results have been incorporated line-by-line into the Company’s and Cancún Airport’s financial statements. (***) These subsidiaries sub-consolidate at the Cancún Airport. Aerostar records its financial information on accounting principles in United States (US GAAP) and in USD, a translation to Mexican pesos is performed and a reconciliation from US GAAP to IFRS is carried out. Aerostar reports its financial information in IFRS, for purposes of consolidating in the Company. The exchange rate used at 2018 and 2019 year end was Ps.19.65 and Ps.18.86 mexican pesos per dollar, respectively. Airplan records and reports its financial information in IFRS as adopted in Colombia and their corresponding IFRIC issued by the IASB and in Colombian pesos. For purposes of consolidating Airplan in the Company, a translations to Mexican pesos is performed. The exchange rate used at 2018 and 2019 year end was Ps.165.29 and Ps.173.63, respectively. (a) Subsidiaries Subsidiaries are all entities over which the Company has control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases. Intercompany transactions, balances, revenues and expenses due to transactions between the group companies were eliminated. The non-realized results were also eliminated. The subsidiaries’ accounting policies are consistent with the policies adopted by the Company. The Company uses the purchase method to recognize business acquisitions. The consideration for the acquisition of a subsidiary is determined based on the fair value of the net assets transferred, the liabilities assumed and the capital issued by the Company. The Company defines a business combination as a transaction in which it obtains control of a business, through which it has the power to govern and manage the relevant activities of the of assets and liabilities of said business with the purpose of providing return in the form of dividends, lower costs or other economic benefits directly to investors. The consideration transferred in the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities incurred and the equity interests issued by the Company. The consideration transferred includes the fair value of any asset or liability that results from a contingent consideration agreement. The identifiable assets acquired, the liabilities and contingent liabilities assumed in a business combination are initially measured at their fair value on the date of acquisition. The Company recognizes any non-controlling interest in the acquired entity based on the proportional part of the non-controlling interest in the net identifiable assets of the acquired entity. Costs related to the acquisition are recognized as expenses in the consolidated statement of income as incurred. Goodwill is initially measured as the excess of the consideration paid and the fair value of the non - controlling interest in the acquired subsidiary over the fair value of the identifiable net assets and the liabilities acquired. If the consideration transferred is less than the fair value of the net assets of the acquired subsidiary in the case of a purchase at a bargain price, the difference is recognized directly in the consolidated statement of income. If the business combination is reached in stages, the book value at the date of acquisition of the participation previously held by the Company in the acquired entity, is remeasured at its fair value at the acquisition date. Any loss or gain resulting from such remeasurement is recognized in the results of the year. At the date of the measurement made by the management, a gain from business combinations was determined for Ps.7,029,200, which was reflected in the consolidated statement of comprehensive income. (b) Changes in the interests of subsidiaries without loss of control Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions, which are transactions with shareholders in their capacity as owners. The difference between the fair value of the consideration paid and the interest acquired in the carrying value of the net assets of the subsidiary is recorded in stockholders’ equity. Gains or losses on the sale of non-controlling interests are also recorded in stockholders’ equity. (c) Disposal of subsidiaries When the Company loses control over one entity, any retained interest in the entity is measured at fair value, recognizing the effect in income. Subsequently, the fair value is the initial carrying amount for the purpose of determining the retained interest as an associate, joint venture or financial asset, as appropriate. Additionally, the amounts previously recognized in Other Comprehensive Income (OCI) relating to those entities are canceled as though the Company had directly disposed of the related assets or liabilities. This means that the amounts previously recognized in OCI are reclassified to income for the period. (d) Investment in joint ventures is accounted for under the equity method The Company applied the guidance under IFRS 11 to the agreement entered into with Highstar for the operation of the LMM Airport through Aerostar as of the initial operation date of February 27, 2013 until May 30, 2017. Under IFRS 11, “Joint arrangements” operations are classified as joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Company has evaluated the nature of its operations and has determined that it is a joint venture. Joint ventures are consolidated by the equity method. Under the equity method, the interest in the joint business is recognized initially at cost and it is subsequently adjusted to recognize the Company’s interest in the earnings after the acquisition, or losses and movements in OCI. When the Company’s interest in the losses of a joint business is the same as or higher than its interest in said business (which includes all long-term interest that forms part of the net investment of the Company in the joint venture), the Company does not recognize additional losses, unless it has incurred obligations or made payments on behalf of the joint venture. Unrealized gains from transactions carried out between the Company and the joint business are eliminated based on the percentage of the Company’s interest in the joint businesses. Unrealized losses are also eliminated, unless the transaction provides evidence of impairment in the transferred assets. The accounting policies for joint ventures have been changed when deemed necessary to guarantee adherence with the policies adopted by the Company. In accordance with IFRS 3 “Business combinations”, as of May 30, 2017 the acquisition is considered a business combination conducted in stages, which means that the fair value of interest previously acquired was also revalued. (e) The additional acquisition in joint venture accounted under the equity method is considered a business combination conducted in stages, which means that the fair value of interest previously acquired was also revalued. 18.3) Translation of foreign currencies Functional currency and reporting currency Items included in the consolidated financial statements of each of the companies of the Company are measured in the currency of the primary economic environment in which the entity operates, i.e., its “functional currency” which is also the reporting currency. The consolidated financial statements are presented in thousands of Mexican pesos, which is the Company’s reporting currency. 18.3.1) Consolidation of subsidiaries with a functional currency different from the reporting currency The results and financial position of Aerostar and Airplan (none of which handle a currency that corresponds to a hyperinflationary economy) expressed in a functional currency other than the reporting currency are converted to the reporting currency as follows: (i) The assets and liabilities recognized in the consolidated statement of financial position are translated at the exchange rate on the balance sheet date. (ii) The stockholders’ equity in the consolidated statement of financial position is translated using the historical exchange rates. (iii) Income and expenses recognized in the consolidated statement of income are translated at the average exchange rate for each year (unless that average is not a reasonable approximation of the effect of translating the results derived from the exchange rates prevailing at transaction dates, in which case the Company uses the respective rates). (iv) The resulting exchange differences are recognized within OCI. Goodwill and fair value adjustments that arise on the date of acquisition of a foreign operation to measure them at fair value are recognized as assets and liabilities of the foreign entity and are converted at the closing exchange rate. 18.3.2) Transactions in foreign currency and results from exchange fluctuations Operations carried out in foreign currency are recorded in the functional currency applying the exchange rates in effect at the transaction date or the exchange rate at the date of the valuation when the items are revalued. Exchange differences arising from fluctuations in the exchange rates between the transactions and settlement dates, or the consolidated statement of financial position date, are recognized in the consolidated comprehensive income statement. 18.4) Cash and cash equivalents Cash and cash equivalents include cash, bank deposits and other highly liquid investments with low risk of changes in value with original maturities of three months or less. As of December 31, 2018 and 2019, cash and cash equivalents consisted primarily of peso and dollar denominated bank deposits and peso denominated investment bonds issued by the Mexican Federal Government. 18.5) Fiduciary rights In accordance with the requirements of the concession agreement, Airplan was required to constitute a trust, with Fiduciaria Bancolombia as trustee, to administer the concession’s resources and to oversee the payment of the concession’s obligations by the concessionaire. Airplan transfers all of the gross income it receives and all of the debt and capital resources it obtains from the administrations of the concession. 18.6) Restricted cash and cash equivalents Restricted cash includes cash and cash equivalents that are restricted in terms of withdrawal or use. The nature of the restrictions includes restrictions imposed by financing agreements, federal agency funds related to capital expenditures, for example, for purposes of Aerostar, PFC and Airport Improvement Program (AIP) or other reserves (e.g., fund for promotion and support of air travel). Aerostar has restricted cash of Ps.2,649 and Ps.26,849 at December 31 , 2018 and 2019 , respectively. Restricted cash and cash equivalents is presented as current if it is expected to be used within twelve months of the filing date. Any restricted fund beyond twelve months is recorded as non-current. Restricted cash is presented in the consolidated statements of cash flows within the investments activities since it is related to the investment in airport infrastructure. 18.7) Financial assets · Accounting policy applied up to December 31, 2017: The Company has applied IFRS 9 following the practical expedient permitted since January 1, 2018, without adjusting comparative figures. As a result, the comparative information for the preceding period continues to be accounted for as per the accounting policy previously in effect, as described below: a. Classification - Up to the accounting policy applied until December 31, 2017, the Company held only financial assets classified as loans and accounts receivable. Loans and accounts receivable are non-derivative financial assets with fixed or determinable payments that are not quoted on an active market. Assets in this category are classified as current assets, unless they are expected to be collected after one year following the closing date, in which case, they are classified as non-current. Loans and accounts receivable are shown in the following captions of the statement of financial position: “Accounts receivable” and “Cash and cash equivalents”. b. Impairment of financial assets - At the end of each year, the Company determines whether or not there is any objective evidence of impairment in each financial asset or group of financial assets. An impairment loss was recorded only when there was objective evidence of impairment as a result of one or more events occurred after initial recognition of the asset (loss event), when the impact of the loss event ( or events) could be reliably estimated on estimated future cash flows derived from the financial asset or group of financial assets. See Note 6 for further details. · Accounting policy applied from January 1 to December 31, 2018 a. Classification - Beginning as from January 1, 2018, the Company classifies its financial assets as per the following measurement categories: a) those measured at amortized cost and b) those subsequently measured at fair value (either with changes in other comprehensive income or in income), not currently held by the Company. The classification depends on the business model of the entity used to handle its financial assets and the contractual features of cash flows. The Company reclassifies financial asset when, and only when, it changes its business model for managing those assets. Financial assets of the Company are measured at amortized costs since the contractual terms comply with the SPPI requirement (Integral Principal Payment Only), and the Company’s business method is that of collect cash flows. b. Measurement - At initial recognition, financial assets at amortized cost are measured at fair value plus transaction costs directly attributable to their acquisition. The transaction costs of financial assets at fair value (with changes via income or OCI) are recorded in income at the time they arise. For assets measured at fair value, profits and losses are recorded in income and OCI. Financial assets with implicit derivatives are entirely considered when determining whether cash flows are merely payments of principal and interest. Accounts receivable are non-derivative financial assets with fixed or determined payments that are not traded in an active market. They are included as current assets, except for maturities of over 12 months after the date of the statement of financial position. They are classified as non-current assets. Loans and accounts receivable are initially valued at fair value, plus transaction costs incurred, and are subsequently recognized at amortized cost. c. Impairment. - Impairment losses are presented as net impairment losses within the operating result. Subsequent recoveries of previously canceled amounts are credited against the same line. For accounts receivable, the Company applies the simplified approach allowed by IFRS 9, which requires that the expected losses over the life of the instrument be recognized from the initial recognition of accounts receivable. See Note 6. 18.8) Leasing 18.8.1) As lessor The leasing of terminal space made by the Company in its capacity as lessor at the terminals is documented by contracts with either fixed income or monthly fees based on the higher amount of a minimum monthly fee or a percentage of the lessee’s monthly revenue. Since the leased assets are part of the concession assets and thus do not belong to the Company, there is no transfer of the risks and rewards of ownership and therefore are classified as operating leases. Revenues from operating leases are recognized as non-aeronautical revenues on a straight line basis over the lease term. Property, plant and equipment leases in which Airplan holds substantially all the risks and rewards of ownership are classified as financial leases. Financial leases are capitalized at the beginning of the lease at the lower of the fair value of the leased asset and the present value of the minimum lease payments. Each financial lease payment is allocated between the liability and the financial costs. Financial lease obligations, net of the financial burden, are presented as debts (financial obligations), current or non-current, depending on whether or not payment maturities are below a 12‑month period. Financial costs are charged to income for the year over the lease period so as to produce a periodic constant interest rate on the remaining balance of the liability for each period. Property, plant and equipment acquired under financial leases are depreciated over the shorter of the useful life of the asset and the lease term. 18.8.2) As lessee Until 2018, leases of property, plant and equipment were classified as operating leases. As from January 1, 2019, leases are recognized as right-of-use assets and lease liabilities on the date the leased assets are available for use by the Company. Right-of-use assets and liabilities arising from a lease under IFRS 16 “Leases” are initially measured at the present value. Lease liabilities include the present value, net of the following lease payments: i) fixed lease payments, less any lease incentive receivable; ii) variable lease payments that depend on an index or a rate, initially measured using the index or rate at the commencement date; and iii) the amounts that the Company expects to pay under residual value guarantees. Lease payments must be discounted at the rate implicit in the lease. In the case of the Company, the interest rate cannot be readily determined. Thus, the lessee’s incremental borrowing rate is used, which is the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment. To determine the borrowing incremental rate, the Group: • • • Lease payments are distributed among principal and interest expense. Interest expense is charged to profit or loss over the lease term to produce a constant periodic interest rate on the remaining liability for each period. Right-of-use assets are measured: • • • Right-of-use assets are generally depreciated on a straight-line basis over the shorter period of the asset useful life and the lease term, and the depreciation expense is recognized in the statement of profit or loss. Payments of short-term leases and leases of low-price assets are expensed by applying the straight-line method. Short-term leases are leases with a term of 12 months or less. To determine the lease term, the Company considers all facts and circumstances creating an economic incentive to exercise an extension option. The reasonable certainty assessment is only reviewed when there is a significant event or a significant change in circumstances that affect such assessment and that are within lessee’s control. At December 31, 2019, there are no contracts regarding which there is a reasonable certainty to extend lease terms. Policy applied before January 1, 2019: As lessor The leasing of terminal space made by the Company in its capacity as lessor at the terminals is documented by contracts with either fixed income or monthly fees based on the higher amount of a minimum monthly fee or a percentage of the lessee’s monthly revenue. Since the leased assets are part of the concession assets and thus do not belong to the Company, there is no transfer of the risks and rewards of ownership and therefore are classified as operating leases. Revenues from operating leases are recognized as non-aeronautical revenues on a straight line basis over the lease term. As lessee Leases in which a significant portion of the risks and rewards of the leased property has not been transferred to the Company as lessee were classified as operating leases. Payments made under an operating lease (net of any incentive received from lessor) are charged to profit or loss according to the straight-line method over the life of the lease. Leases of property, plant and equipment in which Airplan has substantially all the risks and rewards of ownership are classified as financial leases. Financial leases are capitalized at the beginning of the lease to the minor between the fair value of the leased asset and the present value of the minimum lease payments. Each payment of a financial lease is distributed between the liability and the financial costs. The obligations of a financial lease, net of the financial burden, are presented as debts (financial obligations) in current or non-current depending on whether the payment due is less than 12 months. The financial costs are charged to the results during the lease period so that a constant periodic interest rate is obtained on the remaining balance of the liability for each period. Property, plant and equipment acquired under a financial lease are amortized in the shortest period between the useful life of the asset and the term of the lease. 18.9) Land, furniture and equipment Furniture and equipment are recorded at cost less accumulated depreciation and impairment loss. The cost includes expenses directly attributable to the acquisition of those assets and all costs associated with placing the assets in the location and in the condition necessary for them to operate as intended by management. Land is recorded at cost and it is not depreciated. Depreciation of other items of plant and equipment is calculated on the straight-line method based on the residual values over their estimated useful lives. The useful lives from the date of acquisition are 10 years. The useful lives at the acquisition date of the furniture and equipment are as shown below: 2019 2018 Furniture equipment 10 to 20 % 10 to 20 % Machinery 10 to 20 % 10 to 20 % Computer equipment 20 to 33 % 20 to 33 % Transportation equipment 20 to 25 % 20 to 25 % Improvements to leased premises 10 % 10 % The residual values, useful life and depreciation method are reviewed and adjusted, if necessary, on an annual basis. 18.9.1) Land Land represents a territorial extension for which the Company has an obligation of constructing 450 hotel rooms along with FONATUR in Huatulco which are recorded at its cost and are not subject to depreciation. See Note 16c. 18.10) Intangible assets 18.10.1) Concessions The airports that are part of the Company performed the analysis of the following criteria that must be taken into account to know if they are within the scope of IFRIC 12: a. The grantor controls or regulates what services the operator must provide with the infrastructure, to whom it must provide them at what price. · The grantor does not need to have full price control; it is sufficient that the price is regulated by the grantor, the contract or the regulator. · The grantor can control the price through a limit mechanism. · The price can vary from fixed price arrangements to those based on a formula up to a maximum price. b. The grantor controls, through ownership, the right of benefits or otherwise, any significant residual interest in the infrastructure at the end of the term of the agreement. Taking into consideration the foregoing, these criteria are applicable to each of the concessions that the Company has, which is why their measurement and determination will be considered within the scope of IFRIC 12. In addition, at the end of all the concessions, all assets become the property of the nation in which the concession is located. Within the scope of IFRIC 12, the respective assets can be classified as: · Financial assets: when the licensor establishes an unconditional right to receive cash flows and other financial assets independently of the use of the public service by the users. · Intangible assets: only when the licensor agreements do not establish a contractual right to receive cash flows and other financial assets from the licensor, independently of the use of the public service by the users. Airport concessions have been considered within the scope of IFRIC 12 as an intangible asset because they comply with the above provisions and no financial assets have been recognized in that regard. Mexico : Rights-to-use airport facilities and airport concessions include the acquisition of the nine airport concessions and the rights acquired. Amortization is computed using the straight-line method over the estimated useful life of the concessions, (original term of 50 years as of November 1, 1998, 29 years as of December 31, 2019). Aerostar : Aerostar’s airport concession, which includes the obligation to make certain capital expenditures in improvement projects, is considered an intangible asset and is recognized at cost less accumulated amortization and impairment losses. Amortization is calculated using the straight-line method during the term of the agreement (40 years); 34 years remaining as of December 31, 2019. Airplan : In the case of Airplan, the right granted by the Concession Contract No.8000011‑OK and Public Tender No.10000001OL2010, respectively, is recorded as an intangible asset , through which the grantors assign to the Company the regulated and unregulated income corresponding to each of the airports subject to the concession. In turn, the costs per loan that are related to the works in execution are part of the intangible. The intangible asset resulting from the recognition and updating of the estimated income of the contract is amortized based on the proportion of the accumulated income of the contract and the total income. Amortization is recognized in the results of the period. The useful life for the amortization was determined as the duration of the concession and the amortization rate is calculated based on the percentage of execution of the revenues with respect to the total expected income of the financial model that the Company has. The concession remains in effect until the date on which any of the following events occur: (i) the regulated revenues generated are equal to expected regulated revenues, provided that the concession agreement has been in force for at least 24 years or (ii) the concession agreement has been in force for at least 40 years, regardless of whether the regulated revenues generated are equal to the expected revenues. If the regulated revenues generated are equal to the expected revenues before the end of the 24 year period, the concession agreement will remain in effect until the end of such period. Management considers such factors in determining the final year of the concession term, which is 2032 (in accordance with legal guidelines, the concession term may be extended until 2048 as long as the aforementioned requirements established by the grantor are met). Therefore, the concession will have a useful life until at least the year 2032, 13 years remain as of December 31, 2019. 18.10.2) Licenses and commercial direct operation (ODC, by its initials in Spanish) These items are recognized at their cost less the accrued amortization and any recognized impairment losses. They are amortized on a straight line basis using their estimated useful life, determined based on the expected future economic benefits, and are subject to testing when indication of impairment is identified. The estimated useful lives at December 31, 2019 are as follows: Licenses 29 years ODC 29 years Commercial Rights of Aerostar 34 years Commercial Rights of Airplan 13 years 18.10.3) Goodwill Goodwill represents the acquisition cost of a subsidiary in excess of the Company’s interest in the fair value of the identifiable net assets acquired, determined at the acquisition date, and it is not subject to amortization. Goodwill is shown separately in the consolidated statement of financial position and is recorded at cost less accumulated impairment losses, which are not reversed. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold. 18.10.4) Intangible assets acquired as part of a business combination When an intangible asset is acquired as part of a business combination, it is recognized at fair value at acquisition date. Subsequently, intangible assets acquired in a business combination, such as commercial rights, are recognized at cost less the accumulated amortization and the accrued amount of impairment losses. See useful lives of these rights in Note 18.10.2. 18.11) Impairment of long-term non-financial assets The long-term non-financial assets subject to amortization or depreciation are subject to annual impairment tests or more frequently if there are events or circumstances that indicate that they might be affected. Other assets are subject to impairment tests when events or circumstances arise that indicate that their book value might not be recovered. Impairment losses correspond to the amounts where the book value of the asset exceeds their recoverable amount. The recoverable amount of assets is the higher of the fair va

Financial risk management:
Financial risk management:	Note 19 - Financial risk management: The Company is exposed to financial risks that result from changes in interest rates, foreign exchange rates, price risk, liquidity risk and credit risk. The Company controls and maintains the treasury control functions related to transactions and global financial risks through practices approved by its Executive Board and Board of Directors. This note contains information regarding the Company’s exposure to each of the aforementioned risks, and the objectives, policies and procedures to measure and manage risk. The main risks to which the Company is exposed are: 19.1) Market risk 19.1.1) Interest rate risk 19.1.2) Exchange rate risk 19.1.3) Price risk 19.2) Liquidity risk 19.3) Credit risk - credit quality 19.1.1) Interest rate risk The Company has contracted bank loans to partially finance its operations. These transactions expose the Company to interest risk, with the main exposure to the risk of variable interest rates resulting from changes in the market base rates (banks charge interest based on TIIE 28 days plus 1.25 points in 2019 and 2018) that are applied to the Company’s bank loans maturing in 2022 and 2024. Regarding the sensitivity analysis, it has been observed that during 2019 and 2018 the reference rate used by the Company (TIIE) has remained stable. As of December 31, 2019 and 2018 there are no LIBOR loans. Based on this fact, the risk is considered low, derived from the materiality of the possible effect. 19.1.2) Exchange rate risk The Company is exposed to minor risk for changes in the value of the Mexican Peso against the U. S. Dollar. Historically, a significant portion of income generated by the Company (mainly derived from the fees charged to international passengers) is denominated in U. S. Dollars, and despite that, income is invoiced in Pesos at the average exchange rate of the previous month and likewise the cash flows are collected in Pesos. At December 31, 2018 and 2019, the Company is exposed to exchange rate risk for monetary position, as shown below: December 31, 2018 2019 Monetary position: Asset Ps. 45,003 Ps. 164,370 Liability (3,149) (4,853) Ps. 41,854 Ps. 159,517 At December 31, 2018 and 2019, the exchange rate was Ps.18.86 and Ps.19.65, respectively. Had the currency weakened by 5% in 2019 (5% in 2018) with respect to the U.S. Dollar, the Company would have had a loss on monetary position at the close in the amount of Ps.150.4 million in 2019 (monetary loss of Ps.41.1 million in 2018). As of April 9, 2020, the date of issuance of this report, the last known exchange rate was Ps.24.69 19.1.3) Price risk The rate regulation system applicable to the airports of the Company imposes maximum rates for each airport, which should not be exceeded on an annual basis. The maximum rates are the maximum annual income per unit of traffic (one passenger or 100 kg of cargo). If the maximum annual rate is exceed, the government authorities could revoke one or more of the Company’s concessions. The Company monitors and adjusts its income on a regular basis in order for its annual invoicing not to exceed the maximum rate limits. Concentrations: At December 31, 2018 and 2019, approximately 51.07% and 55.02%, of revenue, not including income from construction services, resulted from operations at the Cancún International Airport. 19.2) Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its funding requirements. The Company’s management has established policies, procedures and limits of authority that govern the Treasury function. Treasury is responsible for ensuring liquidity and managing the working capital to ensure payments to suppliers, debt servicing and funding of operating costs and expenses. The following table presents the analysis of the net financial liabilities of the Company based on the period between the date of the statement of consolidated financial position and the maturity date. The amounts presented in the table reflect the undiscounted cash flows, including contractual interest: Under Between 3 months Between 1 Between 2 and At December 31, 2018 3 months and one year and 2 years 5 years Bank loans and interest Ps. 14,506 Ps. 161,009 Ps. 212,959 Ps. 6,829,639 Long term debt 119,680 204,910 208,027 6,749,651 Suppliers 313,577 Accounts payable and accrued expenses 1,557,847 Under Between 3 months Between 1 Between 2 and At December 31, 2019 3 months and one year and 2 years 5 years Bank loans and interest Ps. 14,639 Ps. 223,596 Ps. 228,073 Ps. 6,446,644 Long term debt 111,676 199,696 204,492 6,284,077 Suppliers 245,100 Accounts payable and accrued expenses 1,378,657 The following table shows the Company’s short term liquidity as of: December 31, 2018 2019 Current assets Ps. 6,000,912 Ps. 7,845,856 Current liabilities 2,408,222 2,560,020 Short term position (liquidity) Ps. 3,592,690 Ps. 5,285,836 19.3) Credit risk - credit quality The financial instruments that are potentially subject to credit risks consist mainly of accounts receivable. Income obtained from fares charged to passengers is not guaranteed and therefore the Company faces the risk of not being able to collect the full amounts invoiced in the event of insolvency of its clients, which are the airlines. In recent years, some airlines have reported substantial losses, and the income resulting from fares imposed to passengers coming from the main client airlines are not all guaranteed through bonds or other types of guarantees. Therefore, in the event of insolvency of any of the airlines, the Company would have no certainty of recovering the total sum of amounts invoiced to the airlines for passenger fees. In August 2010, Grupo Mexicana filed for bankruptcy. Grupo Mexicana owes the Company Ps.128 million pesos for passenger fees. As a result of Grupo Mexicana’s bankruptcy, the Company has increased its reserve for uncollectable accounts by Ps.128 million pesos. The Company has determined that it may not be able to collect that amount from Grupo Mexicana. The Company operates under three methods to collect from airlines: a. Credit, mainly offered to airlines with which there is a history of frequent and stable flights, b. Advances, from airlines with reasonably stable flights or that are in the exploration stage of routes or destinations, and c. Cash, mainly offered for Charter flights and airlines with new flights. With this segregation, the Company reduces its collection risk since the airlines that operate under methods b) and c) do not generate accounts receivable. Cash and cash equivalents are not subject to credit risks since the amounts are kept at financial institutions of good standing, and investments are subject to lower significant risk as they are being backed by the Mexican Federal Government or institutions with AAA high market ratings. 19.4) Capital management The objective of management is to safeguard the Company’s ability to continue operating as a going-concern in order to provide returns for stockholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. These activities are monitored through the review of information pertaining to the Company’s operation and the Industry. This effort is coordinated by the CEO. Through a planning method, detailed simulations are formulated of identified risks as they are known. The risks identified are valued in terms of probability and impact and are presented to the proper authorities. The result of all these activities is reported to the market through 20‑F reports, the sole circular and quarterly reports by a financial risk analysis committee that reports to Company’s Board of Directors. 19.5) Fair value Financial instruments at fair value, presented by levels, in accordance with the valuation method used are included in levels 1 and 2. At December 31, 2018 and 2019, the Company has no financial instruments carried at fair value. The different levels have been defined as follows: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices for similar instruments in active markets; quoted prices for instruments, identical or similar, in non-active markets and valuations through models where all significant data are observable in the active markets. Level 3: Asset or liability input that is not based on observable market data (i.e., non-observable). The fair value of financial instruments traded in active markets is based on market prices quoted at the consolidated statement of financial position closing date. A market is considered active if quotation prices are clearly and regularly available through a stock exchange, trader, dealer, industry group, price fixing services, or regulatory agency, and those prices reflect regularly and on current bases the market transactions under independent conditions. The quoted price used for the financial assets held by Company’s is the current offer price.

Critical accounting judgments and key sources of estimation uncertainty:
Critical accounting judgments and key sources of estimation uncertainty:	Note 20 - Critical accounting judgments and key sources of estimation uncertainty: In applying the Company’s accounting policies, which are described below, Company management is required to make judgments, estimates and assumptions about the carrying amounts of assets and liabilities. Estimates and assumptions are based on historical experience and other factors considered relevant. Actual results could differ from those estimates . Critical accounting judgments Significant information on assumptions, critical judgments and uncertainty estimations recognized in the consolidated financial statements are as follows: 20.1 Revenue 20.2 Useful life of the Airplan concession 20.3 Evaluation of impairment of goodwill 20.1 Revenue As mentioned in Note 19.1.3, management regularly monitors and adjusts income so as to avoid exceeding the maximum rate at each of the airports operated by the Company in Mexico, which is the annual maximum income per traffic unit that can be received, and therefore the amount that the Company can record for services rendered whose prices are regulated. If the Company recognized income exceeding that maximum rate, the authorities could cancel one or more airport concessions. Therefore, management regularly monitors regulated income in Mexico to ensure it does not exceed the limit. The application of the procedure established in the concession titles for determining whether revenues are in excess of the maximum rates and securing the necessary information are complex procedures. Among the information used in determining the maximum rate is passenger traffic and cargo statistics, in addition to variables such as the National Producer Price Index (excluding oil), authorized rates for airport services and the Rate for Airport Use. 20.2 Useful life of the Airplan concession The overall duration of the Airplan concession depends on the revenues generated by the Colombian airports. In particular, the concession remains in effect until the date on which any of the following events occur: · The regulated revenues generated are equal to the expected regulated revenues, provided that the concession agreement has been in force for at least 24 years. · The concession agreement has been in force for at least 40 years, regardless of whether the regulated revenues generated are equal to the expected revenues. If the regulated revenues generated by the Colombian airports are equal to the expected revenues before the end of the 24 year period, the concession agreement will remain in effect until the end of such period. Thus, management considers such factors in determining the final year of the concession term, which is 2032; however, in accordance with legal guidelines, the concession term may be extended until 2048 as long as the aforementioned requirements established by the grantor are met. It must be taken into account, for purposes of the expected regulated revenues according to the definition in the concession contract, that the expected regulated revenues will increase once each of the complementary works (mandatory or voluntary) is delivered to the grantor. The Company conducts sensitivity analyses to determine the level of possible changes in the assumptions used to determine the useful life of the concession, in order to determine if the useful life would change significantly. At December 31, 2018 and 2019 the expected total revenues considering the additional works amount to Ps.23,474,154 and Ps.19,217,035, respectively. 20.3 Evaluation of impairment of goodwill Goodwill is evaluated for impairment annually or whenever events or changes in circumstances indicate that there is impairment in the book value of goodwill including changes in tourist preferences, in the economic situation and in security levels in the different countries or other factors affecting passengers making use of our airports. In order to determine whether there is impairment in the value of goodwill, the cash generating unit to which goodwill has been assigned should be evaluated using present value techniques. When applying that valuation technique, the Company employs a series of factors which include historical income, business plans, forecasts and market data. The foregoing is described in greater detail in Note 8.1. As can be concluded from that description, changes in the conditions of these judgments and estimations can significantly affect the evaluated value of goodwill.

Subsequent Event:
Subsequent Event:	Note 22 - Subsequent Event: The COVID-19 outbreak began in December 2019, and on March, 11 2020, the World Health Organization (the “WHO”) designated the outbreak a pandemic. Travel advisories and restrictions have been issued for people traveling to and from certain areas and countries where the COVID-19 outbreak has been concentrated, including, in some cases, the closure of international borders. Airlines have, in many cases, temporarily suspended or reduced flights to and from those areas and countries. On March 19, 2020, the United States issued a travel advisory recommending that citizens avoid all international travel. The following day, on March 20, 2020, the United States closed its border with Mexico, except to essential travel and trade and commerce. On March 23, 2020, the FAA approved a request by the Governor of Puerto Rico to redirect all commercial flights bound for Puerto Rico through LMM Airport and that all passengers be screened by representatives of the Puerto Rico Health Department. On March 30, 2020, the Governor of Puerto Rico, through an executive order of indefinite term, imposed a two-week quarantine on all passengers arriving at the LMM Airport. The LMM airport remains open, albeit with substantially reduced flight and passenger volumes and operations. The government of Colombia suspended commercial aviation for all airports in the country from March 25 to April 13, 2020. As a result, operations at our Colombian airports have been suspended at this time. Mexico’s General Health Council, which reports directly to the President, has recognized COVID-19 as a disease that requires “priority attention” and on March 30, 2020, declared a national health emergency in response to the COVID-19 pandemic. The Mexican government has implemented various measures to control the spread of COVID - 19, including extraordinary actions, such as school closures and the suspension of non-essential activities, in the regions most affected. For purposes of these measures, airports are considered essential and our Mexican airports remain operational. Because the development and spread of COVID-19 began after December 31, 2019, and based on IAS 10, “Events after the reporting period,” the potential effect on financial information derived from the COVID-19 pandemic is considered a non-adjustable subsequent event for the fiscal year 2019. The Company will periodically continue evaluating the impact of the COVID-19 pandemic for subsequent financial statements. Some of our airlines, and other clients, and tenants have asked for assistance, either through discounts on payments owed to the Company or by an extension on payment terms. The Company remains in commercial discussions with those clients and tenants regarding their contracts. The effects of the COVID-19 pandemic on the Company’s operations are still uncertain, however, management expects a significant reduction in passenger traffic in Puerto Rico, Mexico and Colombia, as a result of the actions taken by the Mexican, U.S. and Colombian and other governments, including in the case of Colombia the temporary suspension of commercial aviation, and from the broader reduction in demand for air travel caused by the COVID-19 pandemic. The Company cannot reasonably estimate the length or severity of the COVID-19 pandemic, or the extent to which the disruption caused by the COVID-19 pandemic may materially impact its consolidated financial position, consolidated results of operations and consolidated cash flows in fiscal year 2020. The Company notes the following regarding the impact of the COVID-19 pandemic: a) b) c)

Landlord: The Company did not have to make adjustments to the accounting for its operating leases for which it was the lessor based on the adoption of this standard. · IFRIC 23 Uncertainly over Income Tax Treatments. There was no impact on the adoption of this interpretation. Certain new rules, modifications and interpretations have been published, which are not effective for reporting periods December 31, 2019, and have not been adopted in advance by the Company. These standards are not expected to have a material impact on the Company in current or future reporting periods and in foreseeable future transactions.
Consolidation	18.2) Consolidation The Company’s consolidated subsidiaries, all of them based in Mexico, in which it holds shares at December 31, 2018 and 2019 are as follows: Shareholding percentage (%) Main activity Aeropuerto de Cancún, S.

As of May 26, 2017, the Cancún Airport acquired an additional 10% equity interest in Aerostar, As a result of this acquisition, the Company has a 60% shareholding and now controls Aerostar, therefore Aerostar is consolidated in the Company’s financial statements. (**) Cancún Airport, S. A. de C. V. acquired on October 19, 2017 a 92.42% and later in May 25, 2018 the 7.58% left to obtain the 100% equity interest in Sociedad Operadora de Aeropuertos Centro Norte, S. A. (Airplan), Company that holds the concession for the administration, operation, commercial exploitation, adaptation, modernization and maintenance of the Enrique Olaya Herrera in Medellín, José María Córdova in Rionegro, El Caraño in Quibdó, Los Garzones in Montería, Antonio Roldán Betancourt in Carepa and Las Brujas in Corozal airports, and from that date, Airplan’s results have been incorporated line-by-line into the Company’s and Cancún Airport’s financial statements. (***) These subsidiaries sub-consolidate at the Cancún Airport. Aerostar records its financial information on accounting principles in United States (US GAAP) and in USD, a translation to Mexican pesos is performed and a reconciliation from US GAAP to IFRS is carried out. Aerostar reports its financial information in IFRS, for purposes of consolidating in the Company. The exchange rate used at 2018 and 2019 year end was Ps.19.65 and Ps.18.86 mexican pesos per dollar, respectively. Airplan records and reports its financial information in IFRS as adopted in Colombia and their corresponding IFRIC issued by the IASB and in Colombian pesos. For purposes of consolidating Airplan in the Company, a translations to Mexican pesos is performed. The exchange rate used at 2018 and 2019 year end was Ps.165.29 and Ps.173.63, respectively. (a) Subsidiaries Subsidiaries are all entities over which the Company has control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases. Intercompany transactions, balances, revenues and expenses due to transactions between the group companies were eliminated. The non-realized results were also eliminated. The subsidiaries’ accounting policies are consistent with the policies adopted by the Company. The Company uses the purchase method to recognize business acquisitions. The consideration for the acquisition of a subsidiary is determined based on the fair value of the net assets transferred, the liabilities assumed and the capital issued by the Company. The Company defines a business combination as a transaction in which it obtains control of a business, through which it has the power to govern and manage the relevant activities of the of assets and liabilities of said business with the purpose of providing return in the form of dividends, lower costs or other economic benefits directly to investors. The consideration transferred in the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities incurred and the equity interests issued by the Company. The consideration transferred includes the fair value of any asset or liability that results from a contingent consideration agreement. The identifiable assets acquired, the liabilities and contingent liabilities assumed in a business combination are initially measured at their fair value on the date of acquisition. The Company recognizes any non-controlling interest in the acquired entity based on the proportional part of the non-controlling interest in the net identifiable assets of the acquired entity. Costs related to the acquisition are recognized as expenses in the consolidated statement of income as incurred. Goodwill is initially measured as the excess of the consideration paid and the fair value of the non - controlling interest in the acquired subsidiary over the fair value of the identifiable net assets and the liabilities acquired. If the consideration transferred is less than the fair value of the net assets of the acquired subsidiary in the case of a purchase at a bargain price, the difference is recognized directly in the consolidated statement of income. If the business combination is reached in stages, the book value at the date of acquisition of the participation previously held by the Company in the acquired entity, is remeasured at its fair value at the acquisition date. Any loss or gain resulting from such remeasurement is recognized in the results of the year. At the date of the measurement made by the management, a gain from business combinations was determined for Ps.7,029,200, which was reflected in the consolidated statement of comprehensive income. (b) Changes in the interests of subsidiaries without loss of control Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions, which are transactions with shareholders in their capacity as owners. The difference between the fair value of the consideration paid and the interest acquired in the carrying value of the net assets of the subsidiary is recorded in stockholders’ equity. Gains or losses on the sale of non-controlling interests are also recorded in stockholders’ equity. (c) Disposal of subsidiaries When the Company loses control over one entity, any retained interest in the entity is measured at fair value, recognizing the effect in income. Subsequently, the fair value is the initial carrying amount for the purpose of determining the retained interest as an associate, joint venture or financial asset, as appropriate. Additionally, the amounts previously recognized in Other Comprehensive Income (OCI) relating to those entities are canceled as though the Company had directly disposed of the related assets or liabilities. This means that the amounts previously recognized in OCI are reclassified to income for the period. (d) Investment in joint ventures is accounted for under the equity method The Company applied the guidance under IFRS 11 to the agreement entered into with Highstar for the operation of the LMM Airport through Aerostar as of the initial operation date of February 27, 2013 until May 30, 2017. Under IFRS 11, “Joint arrangements” operations are classified as joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Company has evaluated the nature of its operations and has determined that it is a joint venture. Joint ventures are consolidated by the equity method. Under the equity method, the interest in the joint business is recognized initially at cost and it is subsequently adjusted to recognize the Company’s interest in the earnings after the acquisition, or losses and movements in OCI. When the Company’s interest in the losses of a joint business is the same as or higher than its interest in said business (which includes all long-term interest that forms part of the net investment of the Company in the joint venture), the Company does not recognize additional losses, unless it has incurred obligations or made payments on behalf of the joint venture. Unrealized gains from transactions carried out between the Company and the joint business are eliminated based on the percentage of the Company’s interest in the joint businesses. Unrealized losses are also eliminated, unless the transaction provides evidence of impairment in the transferred assets. The accounting policies for joint ventures have been changed when deemed necessary to guarantee adherence with the policies adopted by the Company. In accordance with IFRS 3 “Business combinations”, as of May 30, 2017 the acquisition is considered a business combination conducted in stages, which means that the fair value of interest previously acquired was also revalued.
Translation of foreign currencies	18.3) Translation of foreign currencies Functional currency and reporting currency Items included in the consolidated financial statements of each of the companies of the Company are measured in the currency of the primary economic environment in which the entity operates, i.e., its “functional currency” which is also the reporting currency. The consolidated financial statements are presented in thousands of Mexican pesos, which is the Company’s reporting currency. 18.3.1) Consolidation of subsidiaries with a functional currency different from the reporting currency The results and financial position of Aerostar and Airplan (none of which handle a currency that corresponds to a hyperinflationary economy) expressed in a functional currency other than the reporting currency are converted to the reporting currency as follows: (i) The assets and liabilities recognized in the consolidated statement of financial position are translated at the exchange rate on the balance sheet date. (ii) The stockholders’ equity in the consolidated statement of financial position is translated using the historical exchange rates. (iii) Income and expenses recognized in the consolidated statement of income are translated at the average exchange rate for each year (unless that average is not a reasonable approximation of the effect of translating the results derived from the exchange rates prevailing at transaction dates, in which case the Company uses the respective rates). (iv) The resulting exchange differences are recognized within OCI. Goodwill and fair value adjustments that arise on the date of acquisition of a foreign operation to measure them at fair value are recognized as assets and liabilities of the foreign entity and are converted at the closing exchange rate. 18.3.2) Transactions in foreign currency and results from exchange fluctuations Operations carried out in foreign currency are recorded in the functional currency applying the exchange rates in effect at the transaction date or the exchange rate at the date of the valuation when the items are revalued. Exchange differences arising from fluctuations in the exchange rates between the transactions and settlement dates, or the consolidated statement of financial position date, are recognized in the consolidated comprehensive income statement.
Cash and cash equivalents	18.4) Cash and cash equivalents Cash and cash equivalents include cash, bank deposits and other highly liquid investments with low risk of changes in value with original maturities of three months or less. As of December 31, 2018 and 2019, cash and cash equivalents consisted primarily of peso and dollar denominated bank deposits and peso denominated investment bonds issued by the Mexican Federal Government.
Fiduciary rights	18.5) Fiduciary rights In accordance with the requirements of the concession agreement, Airplan was required to constitute a trust, with Fiduciaria Bancolombia as trustee, to administer the concession’s resources and to oversee the payment of the concession’s obligations by the concessionaire. Airplan transfers all of the gross income it receives and all of the debt and capital resources it obtains from the administrations of the concession.
Restricted cash and cash equivalents	18.6) Restricted cash and cash equivalents Restricted cash includes cash and cash equivalents that are restricted in terms of withdrawal or use. The nature of the restrictions includes restrictions imposed by financing agreements, federal agency funds related to capital expenditures, for example, for purposes of Aerostar, PFC and Airport Improvement Program (AIP) or other reserves (e.g., fund for promotion and support of air travel). Aerostar has restricted cash of Ps.2,649 and Ps.26,849 at December 31 , 2018 and 2019 , respectively. Restricted cash and cash equivalents is presented as current if it is expected to be used within twelve months of the filing date. Any restricted fund beyond twelve months is recorded as non-current. Restricted cash is presented in the consolidated statements of cash flows within the investments activities since it is related to the investment in airport infrastructure.
Financial assets	18.7) Financial assets · Accounting policy applied up to December 31, 2017: The Company has applied IFRS 9 following the practical expedient permitted since January 1, 2018, without adjusting comparative figures. As a result, the comparative information for the preceding period continues to be accounted for as per the accounting policy previously in effect, as described below: a. Classification - Up to the accounting policy applied until December 31, 2017, the Company held only financial assets classified as loans and accounts receivable. Loans and accounts receivable are non-derivative financial assets with fixed or determinable payments that are not quoted on an active market. Assets in this category are classified as current assets, unless they are expected to be collected after one year following the closing date, in which case, they are classified as non-current. Loans and accounts receivable are shown in the following captions of the statement of financial position: “Accounts receivable” and “Cash and cash equivalents”. b. Impairment of financial assets - At the end of each year, the Company determines whether or not there is any objective evidence of impairment in each financial asset or group of financial assets. An impairment loss was recorded only when there was objective evidence of impairment as a result of one or more events occurred after initial recognition of the asset (loss event), when the impact of the loss event ( or events) could be reliably estimated on estimated future cash flows derived from the financial asset or group of financial assets. See Note 6 for further details. · Accounting policy applied from January 1 to December 31, 2018 a. Classification - Beginning as from January 1, 2018, the Company classifies its financial assets as per the following measurement categories: a) those measured at amortized cost and b) those subsequently measured at fair value (either with changes in other comprehensive income or in income), not currently held by the Company. The classification depends on the business model of the entity used to handle its financial assets and the contractual features of cash flows. The Company reclassifies financial asset when, and only when, it changes its business model for managing those assets. Financial assets of the Company are measured at amortized costs since the contractual terms comply with the SPPI requirement (Integral Principal Payment Only), and the Company’s business method is that of collect cash flows. b. Measurement - At initial recognition, financial assets at amortized cost are measured at fair value plus transaction costs directly attributable to their acquisition. The transaction costs of financial assets at fair value (with changes via income or OCI) are recorded in income at the time they arise. For assets measured at fair value, profits and losses are recorded in income and OCI. Financial assets with implicit derivatives are entirely considered when determining whether cash flows are merely payments of principal and interest. Accounts receivable are non-derivative financial assets with fixed or determined payments that are not traded in an active market. They are included as current assets, except for maturities of over 12 months after the date of the statement of financial position. They are classified as non-current assets. Loans and accounts receivable are initially valued at fair value, plus transaction costs incurred, and are subsequently recognized at amortized cost. Impairment. - Impairment losses are presented as net impairment losses within the operating result. Subsequent recoveries of previously canceled amounts are credited against the same line. For accounts receivable, the Company applies the simplified approach allowed by IFRS 9, which requires that the expected losses over the life of the instrument be recognized from the initial recognition of accounts receivable. See Note 6.
Leasing	18.8) Leasing 18.8.1) As lessor The leasing of terminal space made by the Company in its capacity as lessor at the terminals is documented by contracts with either fixed income or monthly fees based on the higher amount of a minimum monthly fee or a percentage of the lessee’s monthly revenue. Since the leased assets are part of the concession assets and thus do not belong to the Company, there is no transfer of the risks and rewards of ownership and therefore are classified as operating leases. Revenues from operating leases are recognized as non-aeronautical revenues on a straight line basis over the lease term. Property, plant and equipment leases in which Airplan holds substantially all the risks and rewards of ownership are classified as financial leases. Financial leases are capitalized at the beginning of the lease at the lower of the fair value of the leased asset and the present value of the minimum lease payments. Each financial lease payment is allocated between the liability and the financial costs. Financial lease obligations, net of the financial burden, are presented as debts (financial obligations), current or non-current, depending on whether or not payment maturities are below a 12‑month period. Financial costs are charged to income for the year over the lease period so as to produce a periodic constant interest rate on the remaining balance of the liability for each period. Property, plant and equipment acquired under financial leases are depreciated over the shorter of the useful life of the asset and the lease term. 18.8.2) As lessee Until 2018, leases of property, plant and equipment were classified as operating leases. As from January 1, 2019, leases are recognized as right-of-use assets and lease liabilities on the date the leased assets are available for use by the Company. Right-of-use assets and liabilities arising from a lease under IFRS 16 “Leases” are initially measured at the present value. Lease liabilities include the present value, net of the following lease payments: i) fixed lease payments, less any lease incentive receivable; ii) variable lease payments that depend on an index or a rate, initially measured using the index or rate at the commencement date; and iii) the amounts that the Company expects to pay under residual value guarantees. Lease payments must be discounted at the rate implicit in the lease. In the case of the Company, the interest rate cannot be readily determined. Thus, the lessee’s incremental borrowing rate is used, which is the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment. To determine the borrowing incremental rate, the Group: • • • Lease payments are distributed among principal and interest expense. Interest expense is charged to profit or loss over the lease term to produce a constant periodic interest rate on the remaining liability for each period. Right-of-use assets are measured: • • • Right-of-use assets are generally depreciated on a straight-line basis over the shorter period of the asset useful life and the lease term, and the depreciation expense is recognized in the statement of profit or loss. Payments of short-term leases and leases of low-price assets are expensed by applying the straight-line method. Short-term leases are leases with a term of 12 months or less. To determine the lease term, the Company considers all facts and circumstances creating an economic incentive to exercise an extension option. The reasonable certainty assessment is only reviewed when there is a significant event or a significant change in circumstances that affect such assessment and that are within lessee’s control. At December 31, 2019, there are no contracts regarding which there is a reasonable certainty to extend lease terms. Policy applied before January 1, 2019: As lessor The leasing of terminal space made by the Company in its capacity as lessor at the terminals is documented by contracts with either fixed income or monthly fees based on the higher amount of a minimum monthly fee or a percentage of the lessee’s monthly revenue. Since the leased assets are part of the concession assets and thus do not belong to the Company, there is no transfer of the risks and rewards of ownership and therefore are classified as operating leases. Revenues from operating leases are recognized as non-aeronautical revenues on a straight line basis over the lease term. As lessee Leases in which a significant portion of the risks and rewards of the leased property has not been transferred to the Company as lessee were classified as operating leases. Payments made under an operating lease (net of any incentive received from lessor) are charged to profit or loss according to the straight-line method over the life of the lease. Leases of property, plant and equipment in which Airplan has substantially all the risks and rewards of ownership are classified as financial leases. Financial leases are capitalized at the beginning of the lease to the minor between the fair value of the leased asset and the present value of the minimum lease payments. Each payment of a financial lease is distributed between the liability and the financial costs. The obligations of a financial lease, net of the financial burden, are presented as debts (financial obligations) in current or non-current depending on whether the payment due is less than 12 months. The financial costs are charged to the results during the lease period so that a constant periodic interest rate is obtained on the remaining balance of the liability for each period. Property, plant and equipment acquired under a financial lease are amortized in the shortest period between the useful life of the asset and the term of the lease
Land, furniture and equipment	18.9) Land, furniture and equipment Furniture and equipment are recorded at cost less accumulated depreciation and impairment loss. The cost includes expenses directly attributable to the acquisition of those assets and all costs associated with placing the assets in the location and in the condition necessary for them to operate as intended by management. Land is recorded at cost and it is not depreciated. Depreciation of other items of plant and equipment is calculated on the straight-line method based on the residual values over their estimated useful lives. The useful lives from the date of acquisition are 10 years. The useful lives at the acquisition date of the furniture and equipment are as shown below: 2019 2018 Furniture equipment 10 to 20 % 10 to 20 % Machinery 10 to 20 % 10 to 20 % Computer equipment 20 to 33 % 20 to 33 % Transportation equipment 20 to 25 % 20 to 25 % Improvements to leased premises 10 % 10 % The residual values, useful life and depreciation method are reviewed and adjusted, if necessary, on an annual basis.
Intangible assets	18.10) Intangible assets 18.10.1) Concessions The airports that are part of the Company performed the analysis of the following criteria that must be taken into account to know if they are within the scope of IFRIC 12: a. The grantor controls or regulates what services the operator must provide with the infrastructure, to whom it must provide them at what price. · The grantor does not need to have full price control; it is sufficient that the price is regulated by the grantor, the contract or the regulator. · The grantor can control the price through a limit mechanism. · The price can vary from fixed price arrangements to those based on a formula up to a maximum price. b. The grantor controls, through ownership, the right of benefits or otherwise, any significant residual interest in the infrastructure at the end of the term of the agreement. Taking into consideration the foregoing, these criteria are applicable to each of the concessions that the Company has, which is why their measurement and determination will be considered within the scope of IFRIC 12. In addition, at the end of all the concessions, all assets become the property of the nation in which the concession is located. Within the scope of IFRIC 12, the respective assets can be classified as: · Financial assets: when the licensor establishes an unconditional right to receive cash flows and other financial assets independently of the use of the public service by the users. · Intangible assets: only when the licensor agreements do not establish a contractual right to receive cash flows and other financial assets from the licensor, independently of the use of the public service by the users. Airport concessions have been considered within the scope of IFRIC 12 as an intangible asset because they comply with the above provisions and no financial assets have been recognized in that regard. Mexico : Rights-to-use airport facilities and airport concessions include the acquisition of the nine airport concessions and the rights acquired. Amortization is computed using the straight-line method over the estimated useful life of the concessions, (original term of 50 years as of November 1, 1998, 29 years as of December 31, 2019). Aerostar : Aerostar’s airport concession, which includes the obligation to make certain capital expenditures in improvement projects, is considered an intangible asset and is recognized at cost less accumulated amortization and impairment losses. Amortization is calculated using the straight-line method during the term of the agreement (40 years); 34 years remaining as of December 31, 2019. Airplan : In the case of Airplan, the right granted by the Concession Contract No.8000011‑OK and Public Tender No.10000001OL2010, respectively, is recorded as an intangible asset , through which the grantors assign to the Company the regulated and unregulated income corresponding to each of the airports subject to the concession. In turn, the costs per loan that are related to the works in execution are part of the intangible. The intangible asset resulting from the recognition and updating of the estimated income of the contract is amortized based on the proportion of the accumulated income of the contract and the total income. Amortization is recognized in the results of the period. The useful life for the amortization was determined as the duration of the concession and the amortization rate is calculated based on the percentage of execution of the revenues with respect to the total expected income of the financial model that the Company has. The concession remains in effect until the date on which any of the following events occur: (i) the regulated revenues generated are equal to expected regulated revenues, provided that the concession agreement has been in force for at least 24 years or (ii) the concession agreement has been in force for at least 40 years, regardless of whether the regulated revenues generated are equal to the expected revenues. If the regulated revenues generated are equal to the expected revenues before the end of the 24 year period, the concession agreement will remain in effect until the end of such period. Management considers such factors in determining the final year of the concession term, which is 2032 (in accordance with legal guidelines, the concession term may be extended until 2048 as long as the aforementioned requirements established by the grantor are met). Therefore, the concession will have a useful life until at least the year 2032, 13 years remain as of December 31, 2019. 18.10.2) Licenses and commercial direct operation (ODC, by its initials in Spanish) These items are recognized at their cost less the accrued amortization and any recognized impairment losses. They are amortized on a straight line basis using their estimated useful life, determined based on the expected future economic benefits, and are subject to testing when indication of impairment is identified. The estimated useful lives at December 31, 2019 are as follows: Licenses 29 years ODC 29 years Commercial Rights of Aerostar 34 years Commercial Rights of Airplan 13 years 18.10.3) Goodwill Goodwill represents the acquisition cost of a subsidiary in excess of the Company’s interest in the fair value of the identifiable net assets acquired, determined at the acquisition date, and it is not subject to amortization. Goodwill is shown separately in the consolidated statement of financial position and is recorded at cost less accumulated impairment losses, which are not reversed. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold. 18.10.4) Intangible assets acquired as part of a business combination When an intangible asset is acquired as part of a business combination, it is recognized at fair value at acquisition date. Subsequently, intangible assets acquired in a business combination, such as commercial rights, are recognized at cost less the accumulated amortization and the accrued amount of impairment losses. See useful lives of these rights in Note 18.10.2.
Impairment of long term non-financial assets	18.11) Impairment of long-term non-financial assets The long-term non-financial assets subject to amortization or depreciation are subject to annual impairment tests or more frequently if there are events or circumstances that indicate that they might be affected. Other assets are subject to impairment tests when events or circumstances arise that indicate that their book value might not be recovered. Impairment losses correspond to the amounts where the book value of the asset exceeds their recoverable amount. The recoverable amount of assets is the higher of the fair value of the asset less the costs incurred for its sale and value in use. For impairment assessment purposes, assets are grouped at the lowest levels at which they generate identifiable cash flows separately which are largely independent of the cash flows of other assets or the Company’s assets (cash-generating units).Non-financial assets are assessed at every reporting date in order to identify potential reversals of such impairment.
Accounts payable	18.12) Accounts payable Accounts payable are liabilities with creditors for purchases of goods or services acquired during the regular course of the Company’s operations. When payment is expected over a period of one year or less from the closing date, they are presented under current liabilities. If the foregoing is not complied with, they are presented under non-current liabilities. Accounts payable are initially recognized at their fair value and are subsequently measured at amortized cost using the effective interest method.
Bank loans and long-term debt	18.13) Bank loans and long-term debt Loans from financial institutions are initially recognized at their fair value, net of transaction costs. Those funds are subsequently recorded at their amortized cost; any difference between the funds received (net of transaction costs) and the redemption value is recognized in the statement of income during the funding period using the effective interest method. 18.13.1) Refinancing costs When the contractual cash flows of a financial asset are renegotiated or otherwise modified and the renegotiation or modification does not result in derecognition of that financial asset, the Company will recalculate the gross carrying amount of the financial asset and will recognize a modification of profit or loss. The gross carrying amount of the financial asset will be recalculated as the present value of the renegotiated or modified contractual cash flows that are discounted at the original effective interest rate of the financial asset (or effective interest rate adjusted by credit for financial assets acquired or originated with credit originated assets) or, where applicable, the revised effective interest rate. All costs or commissions incurred adjust the carrying amount of the modified financial asset and are amortized over the remaining term of the modified financial asset. 18.13.2) Loan costs Costs of specific and general loans directly attributable to the construction of qualifying assets are capitalized during the period of construction and preparation of the asset for its use. Qualifying assets are those that require a substantial period to be ready and able to be used (usually greater than one year). Financial revenues obtained from temporary investments made with money coming from specific loans that will be used for the construction of qualifying assets are decreased of financial costs eligible for capitalization. The capitalization of costs for loans in foreign currency that generates interests and losses due to foreign exchange fluctuations, are only capitalized up to the amount of interest that would have been generated by loan in national currency, with similar conditions of time.
Derecognition of financial liabilities	18.14) Derecognition of financial liabilities The Company derecognizes its financial liabilities if, and only if, the obligations of the Company are met, are cancelled or if they expire.
Provisions	18.15) Provisions Liability provisions represent a present legal obligation or an assumed obligation as a result of past events, when the use of economic resources is likely in order to settle the obligation and when the amount can be reasonably estimated. Provisions are not recognized for future operating losses. Provisions are measured at the present value of expenses expected to cover the related obligation, using a pretax rate that reflects the actual considerations of the value of money market over time and the specific risks inherent in the obligation. The increase in the provision over time is recognized as an interest expense. When there are similar obligations, the likelihood of the outflow of economic resources for settling those obligations is determined considering them as a whole. In these cases, the provision thus estimated is recorded, provided the likelihood of the outflow of cash with respect to a specific item considered as a whole is remote.
Deferred IT, and tax on dividends	18.16) Deferred IT, and tax on dividends The expense for IT includes both the current tax and deferred taxes. Tax is recognized in the statement of income, except when it relates to items recognized directly in OCI or in stockholders’ equity in which case, the tax is also recognized in OCI items or directly in stockholders’ equity, respectively. Deferred IT were recorded based on the comprehensive method of liabilities, which consists of recognizing deferred taxes on all temporary differences between the book and tax values of assets and liabilities to be materialized in the future at the enacted or substantially enacted tax rates in effect at the consolidated financial statement date. See Note 14. Deferred tax assets are only recognized if future tax profits are expected to be incurred against which temporary differences can be offset. Deferred tax assets and liabilities from the temporary differences arising from the investments in subsidiaries and joint businesses are recognized, except when the Company controls the reversal period for such temporary differences and it is likely that the temporary differences will not be reverted in a near future. Deferred IT are offset when there is a legal right for each entity to offset current tax assets against current tax liabilities and when deferred IT assets and liabilities relate to the same tax authorities. The credits for IT incurred is computed based on tax laws approved in Mexico at the date of the consolidated statement of financial position. Current IT is made up of IT, which is recorded under income for the year in which they are incurred. The tax is based on taxable income. To determine the IT the applicable rate in Mexico for 2018 and 2019 was 30%, the applicable rate for Airplan, according to Colombian legislation for 2018 and 2019 was 33% and the applicable rate for Aerostar , in accordance with Puerto Rico law , for 2018 and 2019 was 10%. Aerostar and Airplan hold undistributed profits which, if paid as dividends, would require the beneficiaries to pay tax. There is a temporary taxable difference, but no deferred tax liability is recognized, as the Company as the controlling entity is capable of deciding the point at which the subsidiary should make distributions. It is not expected to distribute those benefits in the foreseeable future, because both companies would first have to pay off their bank or private debts before they can declare dividends.
Employee benefits	18.17) Employee benefits The present value of the defined benefit obligations is determined by discounting the estimated future cash flows using the interest rates of high-quality corporate bonds denominated in the same currency in which the benefits will be paid and that have expiration terms that are approximate the terms of the pension obligation. In those countries where there is no deep market for such bonds, interest rates on government bonds are used. The net interest cost is calculated by applying the discount rate to the net balance of the defined benefit obligation and the fair value of the plan assets. This cost is included in the expense for employee benefits in the consolidated statement of income. Gains and losses for remeasurements derived from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur directly in OCI. They are included in the accumulated results in the statement of changes in stockholders’ equity and in the consolidated statement of financial position. Variations in the present value of the defined benefit obligation that result from modifications or reductions of the plan are recognized immediately in results as past service costs. Termination benefits Termination benefits are paid when the employment relationship ends before the normal retirement date or when an employee voluntarily accepts the termination in exchange for these benefits. The Group recognizes termination benefits on the first of the following dates: (a) it is committed to terminate the employment relationship of employees in accordance with a detailed formal plan without having the possibility of evading its obligation, and (b) when the entity recognizes restructuring costs in accordance with IAS 37 and involves payment of termination benefits. In the case of an offer that promotes voluntary termination, termination benefits are valued based on the expected number of employees accepting the offer. Benefits that mature 12 months after the reporting date are discounted to their present value. The charge to income for the years ended December 31, 2018 and 2019 was Ps.1,595 and Ps.1,922, respectively. See Note 4. Short-term obligations Salaries for wages and salaries, including non-monetary benefits and accumulated sick leave, which are expected to be fully settled within 12 months after the end of the period in which the employees provide the related service, are recognized in connection with the service of employees until the end of the period and are measured by the amounts that are expected to be paid when the liabilities are settled. Liabilities are presented as current obligations for employee benefits in the consolidated statement of financial position. Share in profits The Group recognizes a liability and an expense for profit sharing based on a calculation that takes into account the profit attributable to the shareholders of the Company after certain adjustments. The Group recognizes a provision when it is contractually bound or when there is a past practice that generates an implicit obligation.
Stockholders' equity	18.18) Stockholders’ equity Capital stock, capital reserves and retained earnings are expressed at their historical cost. The capital reserves consist of the legal reserve, the reserve to repurchase own shares, and the reserve to reflect the effect of translating foreign currency.
Basic and diluted earnings per share	18.19) Basic and diluted earnings per share Basic earnings per share were computed by dividing income available to the stockholders (Ps.4,987,601 and Ps.5,465,823) by the weighted average number of shares outstanding in 2018 and 2019. The number of shares outstanding for the periods from January 1 to December 31, 2018 and 2019 was 300 million. The basic earnings share for the year ended as of December 31, 2018 and 2019 was Ps.16.63 and Ps.18.22, respectively, are expressed in pesos, the diluted earnings per share is equal to the basic earnings per share.
Financial reporting by segments	18.20) Financial reporting by segments The segment financial information is presented in a manner that is consistent with the internal reporting provided to the General Directors in charge of making operational decisions, allocating resources and assessing the performance of the operating segments. The Company determines and evaluates the performance of its airports on an individual basis, after allocating personnel costs and other costs of services, which are incurred by a Company’s subsidiary which hires some of the Company’s employees. The performance of these services is determined and assessed separately by management. All the airports provide substantially the same services to their clients. The performance of (Services) is determined and evaluated separately by management. All airports provide substantially the same services to their customers. Note 2 includes the financial information related to the Company’s different segments, which includes Cancún Airport and subsidiaries (Cancún Airport), showing separately, due to their importance, Aerostar, Airplan, Villahermosa Airport (Villahermosa), Mérida Airport (Mérida) and Servicios Aeroportuarios del Sureste (Servicios). The financial information of the remaining six airports, of RH Asur, S. A. de C. V. and of the holding company (including the investment of the Company in its subsidiaries) has been grouped and is included in the “Others” column. The elimination of the investment of the Company in its subsidiaries is included in the “Consolidation Adjustments” column. Resources are assigned to the segments based on the significance of each one to the Company’s operations. Transactions among operating segments are recorded at their fair value. As of May 26, 2017, the Company consolidates its shareholding in Aerostar as a subsidiary into the Company, increasing its shareholding from 50% to 60%, for which the recognition as a joint venture was until May 26, 2017, and for the period from May 27 to December 31, 2017, and for 2018 and 2019 consolidates Aerostar line by line into the Company's finances. As of October 19, 2017, Airplan, S. A. consolidates as a subsidiary into the Company.
Revenue recognition	18.21) Revenue recognition The accounting policies for the Company’s revenue from contracts with customers are explained in Note 3. With respect to the revenue presented in 2017, it is recognized and disclosed under the previous regulations that in this case is the International Accounting Standard (IAS) 18 - Revenue, as described in the following paragraphs. Revenue comprises the fair value of the consideration received or to be received for services rendered primarily in the ordinary course of the Company’s business. Revenue is presented net of discounts, as well as the elimination of revenues for services between subsidiaries of the Company, as appropriate. The Company recognizes revenue when the amount of it can be valued with reliability, it is likely that the future economic benefits will flow to the entity and specific criteria have been met for each type of service of the Company. Revenues are obtained from aeronautical services (which are generally related to the use of the airport infrastructure by airlines and passengers), non-aeronautical services and constructions services
