Risk Management Expressway service is regarded as core business of the Expressway Authority of Thailand (EXAT). EXAT has a duty to develop and improve expressways, ensuring their safety and compliance with applicable standards, while providing innovative, value-added services. Its businesses are carried out under the concept of economical asset utilization so as to strengthen the potential of expressway business and social benefits. In addition, it places a high value on developing management systems as well as investing to enhance organizational values in accordance with its vision: “Being determined to improve expressways and offer a good service that is economically worthwhile, convenient, fast and safe in a sustainable way.” Risk management has therefore been adopted, in pursuant to COSO-ERM Portfolio Views of Risk Framework, as a tool to support its operation by means of “Value-based Enterprise Risk Management (VBRM). Such an approach emphasizes performing duties using multiple strategies while regarding risk management as a way to create business opportunities, resulting in the achievement of organizational values and benefits. This has been performed in line with the principles/guidelines on risk management and internal control 2012 of the State Enterprise Policy Office, the Ministry of Finance. Risk management plan has been annually reviewed and improved according to changing circumstances for achieving the set objectives and obligation, ensuring that risks are managed in the acceptable level. Based on the previous outcomes of risk management and evaluation of the organization’s quality, it reveals that EXAT has still encountered different risk situations which vary according to changing trends as well as uncertainty from internal and external factors. Therefore, it is essential that EXAT analyze the organization’s risk situations to be able to indicate the organization’s risks. Such risks are managed to ensure its business development opportunities and organizational value enhancement, leading to its sustainable growth under the acceptable risk level. EXAT has performed a review of risk situation analysis by anticipating the future outlook, indication of risk drivers and the cause of risk, enabling EXAT to indicate and divide its key risk factors in fiscal year 2017 into 3 types: finance, strategy, and law and regulation. Three work plans are established accordingly to handle risks as follows: 1. Plan on expressway effectiveness enhancement 2. Management plan on EXAT’s financial performance 3. Management plan on expressway project contract EXAT’s overall risk management effectively links with 5 risk management strategies as described below 1. Value added strategy by diversifying to other business sectors based on systematic use of existing assets 2. Establishment of business opportunity strategy on creating from managing revenues and debts based on cost efficiency 3. Reduction of revenue fluctuation strategy based on development/innovation management of marketing and services 4. Establishment of sustainable strength strategy based on the development of organization learning and the integration of working procedures in line with the organization’s targets/requirements and on reinforcing collaborative networks with partners to manage a commuting, transport and logistics system 5. Enhancement of investment capability strategy based on development/innovation management of financial administration and investment, e.g., setting up an infrastructure fund as well as an asset management company Additionally, in fiscal year 2017, EXAT’s business continuity plan (BCP) has been reviewed/improved to be in accordance with the current circumstances and efficiently cover key work systems. Rehearsal of every business continuity plan has been performed to be in preparation for solving any critical situations which may arise and affect EXAT’s operation. Besides, EXAT has increased a communicating channel to enhance knowledge and create understanding about its business continuity plan for employees. The outcome of risk control and management in fiscal year 2017 reveals that EXAT’s risk management is at the acceptable level, reflecting EXAT’s good risk management. 77

Internal Control The Expressway Authority of Thailand (EXAT) has recognized and developed internal control operation on a continuous basis. Risk-based internal control has been evaluated and systematically integrated with the organizational risk management in the following 5 components: 1) control environment 2) risk assessment 3) control activities 4) information and communication 5) monitoring and evaluation. This has been carried out in line with the State Audit Commission (SAC)’s internal control standards 2001 and the Committee of Sponsoring Organization of the Treadway Commission (COSO)’s international standard framework. In addition, principles and guidelines for risk management and internal control 2012 of the State Enterprise Policy Office (SEPO), the Ministry of Finance, have also been applied to the EXAT’s internal control operation. The summary report on the EXAT’s internal control assessment are annually proposed to senior officials, EXAT Governor, Risk Management Committee, Audit Committee, Board of Directors and Office of the Auditor General of Thailand. Aside from the implementation of the internal control plan approved by the Board of Directors, importance is also given to the use of information technology in the Control Self-assessment (CSA). All work units (12 departments, 39 divisions, 152 sections) have performed CSA, either in assessing internal control components or evaluating their internal control activities, under an internal control system namely Intranet-based Internal Control Management System since fiscal year 2011. This system encourages executives from the section head level to participate in managing and reporting internal controls in accordance with the established system so as to facilitate and constantly update the implementation while reducing operational processes. In fiscal year 2017, EXAT has developed an Internal Control Management System Mobile Application. The application helps facilitate internal control operation and enhance the ability to perform anytime, anywhere, enabling users including section heads and directors (division/ department/office) to record results, approve reports and access relevant information more conveniently and rapidly. 1st Set of Images : Use of Intranet-based Internal 2nd Set of Images : Use of Internal Control Management Control Management System System Mobile Application The results of EXAT’s internal controls in fiscal year 2017 are found to meet the same standards while achieving adequacy, appropriateness, efficiency and effectiveness according to the set objectives. 78

RofesEexaprrcehss&wDayevSeelorvpicmeent Mobile Application for Smart Traffic Information by the Expressway Authority of Thailand (EXAT Traffic) Since 2011, EXAT has used mobile technology (Mobile Application for Smart Traffic Information) to specifically report on traffic conditions on expressways and provide users with useful information for making their pre-trip and enroute decisions. In 2017, EXAT has upgraded the mobile application to version 3.0 namely “EXAT Traffic”. Based on the latest information on the application users in August 2017, EXAT Traffic has been used more than 125,000 times/month (both on iOS and Android), with 18:00-20:00 hrs. being the peak hours for the app usage, and the majority of the users (over 40%) being those traveling on Si Rat Expressway. The new mobile application version 3.0 has additional up-to-date features such as Social Share, Location Base Service, Around Me and VDO Streaming from CCTV cameras on expressways. Such features allow EXAT Traffic users to access smart traffic information, enabling them to make wise decisions in planning their trips with expressways, and truly enjoy “Comfort and Safety on the Expressway”. EXAT Traffic can be downloaded from Google Play and App Store by searching for “EXAT Traffic”. Traffic congestion identification by using traffic report display Smart Map, or a map containing color-coded lines, which provides information on traffic conditions, has been widely used by a large number of road users as it helps them plan their trips effectively. Aside from the aforementioned benefit, Smart Map can also be used for identifying congested areas as well as causes of congestion. Currently offered by various providers, such a map identifies traffic congestion levels using indicators that suit their existing resources. For example, TOMTOM Traffic uses Congestion Level to specify congested spots while Longdo Map employs Longdo Traffic Index to display congestion on each road. EXAT is one of the providers that offers traffic reporting service through the internet and smartphones in the form of a schematic map featuring green, yellow and red lines to show the level of congestion. However, this map gives a real-time report and has not collected any traffic results. Providing that these results are stored in a database, EXAT will be able to bring them to analyze and pinpoint congested areas as well as their severity levels using time spent in congestion and percentage. Once congested areas are identified, EXAT will then develop a simulation model, rather than on-site testing which may affect expressway users, in order to test measures to alleviate the problems until the best measure is achieved and applied on expressways. EXAT has created a schematic map database which demonstrates traffic conditions on expressways, analyzes congested spots in expressway networks and sorts congestion by severity level on a quarterly basis. A simulation model has also been developed to seek out traffic solutions and assess economic benefits, which will be taken into account for considering investment worthiness of the solutions. In addition to traffic congestion identification, EXAT has initiated a simulation model to analyze how much expressway users will gain if red lines are solved and turned into green. The result reveals that the value of time and vehicle operating costs for the users will be saved up to 11.4 million Baht per year from a reduction of 1 kilometer or 1 hour in traffic congestion. 79

Use of Microscopic Simulation Model for Analyzing Measures to Solve Traffic Problems Case Study: Bang Na (Inbound) Area near Sukhumvit Soi 62 EXAT has conducted a quarterly research on the traffic congestion identification from the traffic condition reporting map 2017. It is found that the Bang Na (Inbound) area near Sukhumvit Soi 62 has always faced a long-time traffic jam for all three quarters due to its physical bottleneck and high quantity of vehicles during peak hours (including those coming from Bang Na Toll Plaza and Chalong Rat Expressway). Realizing the existing problem, EXAT thus developed a microscopic simulation model and adjusted it to closely resemble the problem area to test measures for mitigating the congestion. After completion of the analysis, it was found that traffic line improvement could help reduce the queue length of vehicles running from Bang Na Toll Plaza by 1 kilometer and the travel time through Sukhumvit Soi 62 ramp by 3 minutes. Aside from this approach, alternately releasing the traffic flow at an appropriate time by officers can also decrease the queue length by 1 kilometer and the travel time by 5 minutes.

It is found that approximately 1,800 accidents happened on expressways per year. EXAT has attached importance to the prevention and settling the matter urgently. This is achieved by analyzing accident-prone black spots on expressways through the Geographic Information System (GIS) by using the Kernel Density Estimation (KDE) and Rate Quality Control (DF) methods. The occurrence statistical data from the Incident Report system database is therefore applied to a spatial analysis so as to reveal overlapping points of black spots on expressways from both methods. The achieved outcomes are presented in the form of a map displaying hazardous spots on the expressways which will be easy to use in finding a suitable preventive measure that can decrease the number of future accidents on the expressways.

Its responsibility is mentioned under the paragraph regarding the auditor’s responsibility to the auditing of financial statements in the report of the Office of the Auditor General. The Office of the Auditor General is independent in accordance with the rules for state audit prescribed by the State Audit Commission and ethical requirements of persons who conduct accounting profession prescribed by Federation of Accounting Professions relevant to financial statement audit. In addition, the Office of the Auditor General has also assumed other ethical responsibilities in accordance with these state audit rules and ethical requirements. The Office of the Auditor General believes that the audit evidence obtained is sufficient and appropriate for using as basis for its opinion. Emphasis of Matter and Event The Office of the Auditor General would like to draw attention to the Note to Financial Statements No. 4.25, relating to contingent liabilities as of September 30, 2017. The Expressway Authority of Thailand has contingent liabilities resulting from litigation of 22 cases, amounting to 29,280.25 million Baht.

Other Information The executive is responsible for other information, comprising the information included in the annual report but not including the financial statements and the auditor’s report therein. The executive will prepare annual report for the Office of the Auditor General after the date in this auditor’s report. The opinion of the Office of the Auditor General does not cover other information and it does not give confidence in respect of other information. The responsibility of the Office of the Auditor General in relation to the financial statement audit is to read and consider whether other information contains any material inconsistency with the financial statements or knowledge obtained from its audit or there is any material misstatement of fact or not. Having read the annual report, if the Office of the Auditor General concludes that there is a material misstatement of fact, it must communicate this matter with those charged with governance. The responsibility of executive and those charged with governance for the financial statements The executive is responsible for preparation and presentation of these financial statements accurately in accordance with financial reporting standards and is responsible for the internal control which the executive considers as necessary for preparing financial statements without any material misstatement of fact, whether due to fraud or error. In the preparation of the financial statements, the executive is responsible to assess the business ability to continue as a going concern, properly disclose matter related to going concern and use going concern assumption, unless the management intends to liquidate business or to cease operations or unable to continue the operations, Those charged with governance are responsible to oversee the financial statement preparation process of the business. 96

The auditor’s responsibility The objectives of the audit made by the Office of the Auditor General are to bring about reasonable confidence that the financial statements do not contain any material misstatement of fact, whether due to fraud or error, and to present the auditor’s report that includes the opinion of the Office of the Auditor General. Reasonable confidence refers to the high level of confidence but it is not an assurance that the work conducted under the generally accepted auditing standards will always be able to uncover the material misstatement of fact. The misstatement of fact may arise from fraud or error and considered material when it can be reasonably estimated that each or every item of the misstatement of fact will affect the economic decision making of the users of the financial statements To conduct the audit under the generally accepted auditing standards, the Office of the Auditor General has used its discretion, observation and professional skepticism throughout the audit. The work performed by the Office of the Auditor General includes; • To identify and assess risk of material misstatement of fact in financial statements, either due to fraud or error, design and conduct work in accordance with audit procedures to respond to these risks, and obtain sufficient and appropriate audit evidence for using as basis in the expression of opinions of the Office of the Auditor General. The risk of failing to identify material misstatement of fact due to fraud will be higher than the risk arising from error, because fraud may relate to collusion, forgery, willful failure to display information, misrepresentation or management override of internal controls. • To understand the internal control system relevant to the audit in order to design audit procedures that are appropriate in the circumstances but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. • Evaluate the appropriateness of the accounting policies used by executives and the reasonableness of accounting estimates and disclosure of related information prepared by executives. • To conclude about the appropriateness of going concern basis applied by executives and from audit evidence obtained, whether there is any material uncertainty in respect of an event or situation that may cause reasonable doubt about the ability of the entity to continue operating or not. If it is concluded that there is any material uncertainty, the Office of the Auditor General must mention so in the auditor’s report, by making remark about the disclosure of information in the relevant financial statements, or if the disclosure of information is not sufficient, the opinion of the Office of the Auditor General will be changed. The conclusion of the Office of the Auditor General depends on the audit evidence obtained up to the date in the auditor’s report. However, future event or situation may cause the entity to cease the operation. • Evaluate the presentation, structure and contents of financial statements in whole, as well as the disclosure of information, to see whether the financial statements display transactions and events in a form that make the information presented accurately or not. The Office of the Auditor General has communicated important matters with those charged with governance, including the scope and time of auditing as planned, significant issues found from the audit, as well as significant defect in the internal control system, if discovered during the audit of the Office of the Auditor General.
