Energy Risk Management Policy SECTION 1 PROGRAM OVERVIEW 1.1 Introduction The City of Denton's municipally owned electric utility, operated under the trade name of Denton Municipal Electric ("DME"), is in the business of providing affordable and reliable energy and energy services to its customers in an environmentally sustainable manner. This Energy Risk Management Policy ("Policy") has been developed to establish a comprehensive framework for DME to meet and exceed the overall goals and objectives set by the City Council, subject to approved risk tolerances. This Policy provides specific controls (e.g., segregation of duties, oversight, etc.) for the management of strategic and operational risks and establishes guidelines for DME to plan, execute and control the risks inherent in the generation, purchase and sale of energy for its retail customers. The resulting framework shall govern DME's energy portfolio activities through which City Management and DME personnel identify, capture, measure, manage, control, monitor and report financial and other risks. This program specifically addresses management of energy portfolio risk and provides a framework to maintain proper controls over portfolio activities as they change over time. 1.2 Objectives DME's energy portfolio consists of its assets such as power plants, power supply contracts of varying delivery patterns and maturity, wholesale physical and financial hedges', and retail load obligations. A number of inherent risks are associated with DME's energy portfolio, including market (price) risk, volumetric risk, operational risk, organizational risk, counterparty credit risk, liquidity (funding) risk, and regulatory and legal risks (for more detail, see Appendix A for a summary of DME's portfolio risks). DME manages these risks to achieve its core business objectives of delivering energy to its customers at reasonable and stable rates. Key risk management objectives and performance measures are shown in the table below. Objective Performance Metric Reduce risk Reduction in exposure to price volatility and volumetric variability ' As used in this Policy, physical and financial hedges are market transactions used to offset pre -financial existing risk in the portfolio, and are generally used to reduce price exposure associated with DME supply and demand, price volatility or transmission congestion.

Energy Risk Management Policy Competitive costs Comparison of actual energy costs (including hedges and ERCOT balancing transactions, but excluding PPAs) to the average annual ERCOT Day Ahead Market (DAM) price, plus a hedging premium Reasonable rates Comparison of DME average rate to that of other Texas municipal utilities 1.3 Energy Risk Management Framework DME's Energy Risk Management Policy is built around a framework that includes the following four elements: Organizational Objectives, Risk Mitigation and Measurement, Portfolio Management and Risk Control Infrastructure. Each of these elements is discussed further below. 1.3.1 Organizational Objectives The Risk Management Committee ("RMC") approves goals, strategies, and objectives which help define the appropriate portfolio management activities that are undertaken by DME. This is done in coordination with strategic and business planning activities conducted to establish the budget and through periodic strategic planning activities. 1.3.2 Risk Mitigation and Measurement As part of clarifying organizational objectives, this Policy defines the EMO's role in identifying, measuring and mitigating energy risks. DME's risk mitigation practices focus on monthly hedging plans and targets, along with transaction and risk exposure limits. 1.3.3 Portfolio Management DME engages in transactions that are conducted in accordance with hedging targets and risk management and transaction limits specified in connection with this Policy and in broader DME policies and operating procedures. 1.3.4 Risk Control Infrastructure DME maintains a collection of internal controls, systems, and processes necessary to achieve the objectives of this Policy. These controls comprise DME's energy risk control infrastructure and includes provisions for: • Energy Risk Management Organization Structure and Responsibilities Page 6 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure.

Upon adoption by the City Council, this Policy shall be implemented through a supporting set of standard operating procedures ("EMO Procedures Manual"). The operating criteria and parameters shall be updated as necessary to reflect changes in market conditions and staffing levels. All standard operating procedures shall be approved by the RMC. All departmental procedures that may impact DME's energy portfolio shall be in full compliance with this Policy. DME executive management shall evaluate the degree of detail necessary in the operating procedures and may require that additional procedures be developed and implemented.

Energy Risk Management Policy 4. In conjunction with the quarterly RMC meetings, the consultant will provide a report to the RMC which will include, but not limited to: • Risk and position reports • Benchmark analysis • Recommendations, as needed, for changes to DME's risk management program 2.2 Front, Middle, and Back Offices The "Front -Middle -Back Office" model provides for segregation of duties and efficient administrative support. It is a way to segregate DME energy management activities into transactional ("Front Office"), independent risk control and transaction compliance ("Middle Office") and financial, accounting, and contract administration support ("Back Office") functions. 2.2.1 Front Office The Front Office is primarily responsible for managing the energy supply portfolio associated with DME's wholesale market activities and directing its daily physical and financial trading. The Front Office directly executes physical or financial transactions to support activities such as management of fuel, power, congestion, ancillary services procurement, environmental attributes, and wholesale sales activities as well as develops measurable hedge strategies and plans at least annually (see Appendix E for details on hedging framework). Specific responsibilities of Front Office personnel include: 1. Evaluating whether prospective strategies are consistent with program objectives and this Policy. 2. Monitoring the energy marketplace for structural changes, changes in counterparties and market liquidity, and new supply and hedging market instruments. 3. Advising the RMC of significant changes in the market and in the liquidity of approved hedging instruments, along with advising the RMC of the need for seeking Council approval of in new hedging instruments that may help DME achieve its risk objectives. New hedging instruments shall be approved based on the guidelines shown in Appendix E — New Product / Market Instrument Approval Checklist. 4. Managing the portfolio of positions in physical and financial energy and energy - related commodities in a manner consistent with DME's risk management Page 11 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy objectives and the corresponding Hedge Strategies contained in Appendix E — Forward Hedging Strategies and Plans. 5. Executing physical and financial transactions with approved counterparties. 6. Recording details of financial and physical transactions for DME's risk information system. 7. Ensuring that transactions are in compliance with DME's Energy Risk Policy. The Front Office oversight role is accomplished through supervisory review and approval. DME's Front Office consists of Market Operations and the Market Analytics group. 2.2.2 Middle Office The Middle Office is responsible for monitoring compliance with this Policy, for assuring that energy transactions and exposures are within authorized limits and meet minimum targets, and for reporting the market exposure associated with all transactions entered into by the Front Office on an ongoing basis. The Middle Office institutes and reviews energy portfolio management activities, such as portfolio credit exposure, transaction compliance and approval of counterparties. The Middle Office also quantifies risk exposure of native business activities (including both price and volumetric uncertainty), excluding hedges. In the event hedge decisions do not achieve program objectives, the Middle Office will determine why the objectives were not achieved and recommend to the RMC how to re -align hedge decisions with program objectives to promote improved effectiveness. The Middle Office responsibilities include monitoring DME's energy management risk exposures and mitigation measures and ensuring compliance with policies, guidelines, and procedures. In connection with this responsibility, the Middle Office maintains a compliance log of any operational and/or procedural violations, which can be used to monitor issues and their severity, frequency and resolution. Additionally, the Middle Office is responsible for recommending to the RMC when changes in policy or operating procedures are required. These recommendations may involve the temporary or permanent halting of transactions with one or more counterparties, and any other topic the Middle Office believes represents potential unacceptable risk exposure. The Middle Office adopts and updates, as necessary, the Energy Risk Management Policy, guidelines and procedures so that portfolio management functions occur in compliance with Energy Risk Management Policies and energy risk procedures and guidelines.

Energy Risk Management Policy Specific responsibilities of the Middle Office include the following: 1. On a daily basis, confirms and reconciles physical and financial transactions, including conditions, quantities, and amounts to be paid and dates. The Middle Office verifies and reconciles every position that has been entered into by Front Office to ensure that the terms recorded and understood by DME to match the terms actually agreed upon with counter parties and/or brokers. 2. Compares energy portfolio to the market (market to market) by collecting and validating market prices, and preparing position reports identifying the financial positions, physical positions, anticipated physical exposures, and the market value of the energy portfolio(s) on a position -by -position and aggregate basis. 3. Operates risk measurement, performance, and valuation models, including various stress tests. 4. Prepares routine risk reports, including those identified in Section 4.2 — Required Reports. 5. On a daily basis, confirms that all exposures and activities comply with authorized market instruments as contained in Appendix D — Approved Types, the risk limits as contained in Appendix A— Risk Exposure and Transaction Limits and hedge coverage targets as contained in Appendix E— Forward Hedging Strategies and Plans. In doing so, the Middle Office monitors transactions and position limits, review daily positions, and activity reports, and ensures that trading instruments are in compliance with current hedging strategies and are permissible. 6. Follows the remedial actions process in the event of any risk limit or hedge target breaches. 7. Ensures all transactions are in compliance with DME's Energy Risk Policy. 8. Generates and sends written confirmations to counterparties to ensure terms and conditions are mutually agreed upon. 2.2.3 Back Office The Back Office's primary responsibility is to ensure that financial records of DME's energy management operation accurately reflect the current state of energy risk management and power supply portfolio management activity. The Back Office is responsible for verifying supply payments, invoicing, and settlements. The Back Office is also responsible, in coordination with City of Denton Finance, AR, and AP departments, for accurately calculating and booking the financial results of energy transaction activities, billing, and accounts payable, as well as recording, reporting and accounting for risk management and hedging. Specific responsibilities of the Back Office include the following: Page 13 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure.

Energy Risk Management Policy SECTION 3 MARKET RISK PROTOCOLS AND EXPOSURE CONTROL 3.1 Market Risk Protocols The following market risk protocols shall govern DME's participation in wholesale energy markets. Specific limits, methodologies, reports, operational procedures and approval processes are detailed in the EMO Procedures Manual. • DME will ensure that it has full knowledge of its energy portfolio position and the resulting exposure, and understands the implications of its energy management activities; • Only personnel authorized by the DME General Manager, or his designee, pursuant to a written Delegation of Authority Memorandum can transact on behalf of DME in the wholesale energy market (see Transaction Limits section of Appendix B); • Personnel involved with DME's energy management activities will ensure they obtain competitive prices, transact "at the market" and that counterparty credit risk is diversified by setting up master enabling agreements [such as the International Swaps and Derivatives Association, Inc. (ISDA), Edison Electric Institute (EEI), and the North American Energy Standards Board (NAESB)] with as many pre -qualified financial counterparties as possible. • DME may only transact in wholesale energy -market products authorized by this Policy. • DME may only transact within transaction limits approved and defined in this Policy. • All wholesale energy transactions will be carried out on recorded phone lines, electronic trading platforms, or other media that can be recorded and documented; • Metrics for assessing DME's market risk exposure will be specified, measured, monitored, and reported on a regular basis to the RMC; • On a daily basis, all wholesale market transactions will be recorded in the official system of record which will capture and report physical and financial positions so that each can be reviewed separately and in total so that net volume and price risk and collateralization requirements can be accurately assessed and managed in real time. This system will also serve as a central check and balance tool; therefore, it will allow for reconciliation of physical and financial confirmations with transactional input. This system will also support and report risk information. • Models and inputs for valuation and risk measurement and mitigation shall be subjected to a validation and change control process. The models employed and associated processes shall be described in detail in the EMO Procedures Manual; and Page 15 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy 3.2 Authorized Transactions Authorized types of transactions are addressed in Appendix D of this Policy. These transactions types are, and shall continue to be, focused on supporting the energy portfolio goals of the City Council and this Policy. 3.3 Market Risk Control An important element to any energy risk management and mitigation program is the regular identification, measurement, and communication of market risk. DME's net "open" position (i.e., whether it needs to buy or sell energy products on a daily, hourly, monthly or annual basis to balance the energy portfolio) and the market exposure associated with its net open positions shall be quantified and compared against exposure limits contained in this Policy and discussed, on a regular basis, within the RMC. Market exposure associated with these net positions shall be quantified using forms of measurement approved by the RMC. The market exposure measurement criteria shall be reviewed at least annually and consider changes in DME's net positions and existing and projected market conditions. The Middle Office shall have primary responsibility for coordinating the development, maintenance, and modification all market measurement methodologies within DME and for recommending approval of these methodologies by the RMC. 3.3.1 Risk Tolerance For the purposes of this Policy, DME's Energy Risk tolerance is defined by the degree of uncertainty that DME can accept in its future financial ratios and customer rates on a projected basis. DME's Energy Risk tolerance and measurement of Energy Risk shall include "at risk" forms of risk measurement such as Cash Flow at Risk (" CFaR") or Value at Risk ("VaR"), augmented with scenario analysis and stress testing. These forms of risk measurement are described in more detail in Appendix A — Risk Exposure and Transaction Limits and in sections of the EMO Procedures Manual. 3.3.2 Transaction and Exposure Limits The setting of and the adherence to transaction limits is an important control element to ensure DME does not assume greater aggregate energy market exposure than is intended and helps ensure that the transaction strategy level is appropriate at various levels of aggregation (e.g. by commodity, delivery period, strategy, energy portfolio, etc.). Appendices B and D, along with the EMO Procedures Manual, contain the Approved Transaction Types and the Transaction Limits for DME. It is the responsibility of the Front Page 16 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy Office, Middle Office and the RMC to utilize these limits to manage and mitigate risk - taking activities. The Front Office shall be responsible for maintaining exposures within prescribed limits and for recommending changes to those limits to the RMC when market conditions or operating circumstances result in limits becoming ineffective or inappropriate in controlling these activities. The Middle Office shall be responsible for monitoring compliance with the Transaction Limits, and obtaining approval from the RMC for any changes to Transaction Limits or the Transaction Limit structure. It is the responsibility of the Middle Office and Front Office to ensure that Transaction Limits are strictly enforced. 3.3.3 Stress Testing In addition to mitigating and measuring financial exposure using the methods above, stress testing is used to examine performance of the energy portfolio under extreme adverse conditions. In stress testing, extreme market conditions are applied to the portfolio to determine how the portfolio will perform under such conditions. Stress testing requires thorough evaluation of past market periods to determine those that would represent severe outcomes. In addition, the performance of the portfolio is also estimated for individual and combined potential market conditions. Such conditions are intentionally chosen to represent adverse conditions and combinations of conditions, even if they are extremely unlikely. The Middle Office shall design and maintain a stress testing program, in consultation with the Front Office. The stress testing approach shall be reviewed by the Middle Office regularly, and the stress testing program shall be presented to the RMC for review on at least an annual basis. 3.3.4 Model Validation and Controls A risk commonly faced by those involved with energy management activity is model risk — the risk that either the methodology or assumptions used to value the portfolio becomes invalid. Inaccurate assumptions and incorrectly designed models can cause risk management problems in every market. However, the complexity of energy models and their extended lifetimes, make these problems especially common in the energy markets. Model risk occurs primarily for two reasons: Page 17 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy • The model may have fundamental errors the user is unaware of and may produce inaccurate outputs when viewed against the design objective and intended business uses. • The model may be used incorrectly or inappropriately. Ensuring adequate model documentation is an important control for managing modeling risk. This requires both organizing model information and accountability from people using and developing models. DME keeps a record of all internally and externally developed models used in its operation (see EMO Operating Procedures 1-4), including • a description of the information input component (assumptions and data used by the model, including quantitative approaches whose inputs are partially or wholly qualitative or based on expert judgment), • version control (when key model inputs or model processes change) • processing component (which transform inputs into estimates), and • reporting component (which translates the estimates into useful business information). The Middle Office will review and validate models used by DME and report to the RMC annually. 3.4 Credit Risk Control Credit Risk is the potential impact on DME's financial performance due to the chance of non- performance in payment or delivery (either physical or financial) by an energy entity that has executed a commercial agreement with DME to buy and sell energy ("counterparty"). DME actively mitigates its energy credit risk by making informed decisions regarding which counterparties to transact with and to what degree. Credit risk is defined as the risk of counterparty nonperformance, or failure to deliver its obligation (whether with an energy product itself or the payment of amounts owed). 3.4.1 Credit Policies DME mitigates its energy credit risk by • Incorporating the expected transacting volumes, timing, and expected energy prices, Page 18 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy when establishing an energy credit risk tolerance for a calendar year; • Assessing counterparty creditworthiness and establishing credit limits for counterparties based on that assessment; • Requiring a counterparty to be assigned a credit limit prior to transacting with it; • Monitoring and assessing market and counterparty events to adjust credit limits as appropriate; • Calculating and reporting the maximum expected loss if a counterparty defaults ("counterparty credit exposure"); and 3.4.2 Credit Limits The EMO Procedures Manual includes a credit limit framework for DME's counterparties based on various factors such as debt ratings and financial statistics. Specific counterparty credit limits include consideration of financial ratios, audited financial statements, and asset quality. Credit limits on all counterparties are reviewed at least semi-annually by the Middle Office, or immediately if their business conditions change or their credit rating has been downgraded. Prior to execution of any transaction with a counterparty, the Front Office verifies that the counterparty has available credit. In addition, no transaction shall be executed that will cause the counterparty credit limit to be exceeded unless explicitly approved by the RMC. 3.4.3 Counterparty Credit Function The counterparty credit function concerns counterparty credit analysis and approval of new and existing counterparties as well as the calculation, aggregation, monitoring and reporting of credit exposures. DME's credit function is managed by the Middle Office and reports to the DME Compliance Manager. The objective of the counterparty credit function is to minimize the potential adverse financial impacts on DME in the event of a potential default by a counterparty. The counterparty credit function will minimize DME's credit exposure and potential adverse financial impacts by: • Establishing a credit risk mitigation structure within the energy risk management program; • Providing a framework to enable DME to qualify energy suppliers and transact with approved counterparties; • Determining counterparty transacting parameters ("transaction limits") to Page 19 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy conservatively control and measure DME's exposure to any one supplier; and • Implementing conservative business processes and procedures (to be included in the EMO Procedures Manual) to gather and monitor financial information on each counterparty to estimate counterparty credit exposures 3.5 Information Systems and Models Energy risk management information systems consist of the data, models and other software and hardware used to collect, analyze, test, and validate transactions within DME's portfolio in order to monitor and control risk. Although various departments within the City of Denton or DME may have responsibilities for using and maintaining DME's risk management systems, the Middle Office shall have overall responsibility for ensuring that the systems are sufficient to perform the risk management functions outlined in this Policy. As part of a service level agreement with the City of Denton Technology Services, the Middle Office shall also be responsible for maintaining the security, integrity and reliability of the software used for energy risk management purposes (e.g. valuation models, administrative and reporting software, energy risk management databases, etc.). In accordance with the Service Level Agreement between DME and the City of Denton Technology Services, Technology Services shall be responsible for maintaining the integrity and reliability of the hardware used for both energy management and energy risk management purposes, including business continuity, disaster protection and recovery plans.

Energy Risk Management Policy SECTION 4 RISK REPORTING 4.1 Risk Management Reporting Policy Key to energy risk management is the monitoring of risks and the accurate and timely information that must be provided to all parties involved in any aspect of energy risk management to allow them to perform their functions appropriately. The separation of execution and reporting responsibilities ensures that timely and accurate information is being reported. On an annual basis, the RMC Chairman will meet with the PUB and City Council and provide details of the DME's forward purchases, market exposure, credit exposure, counterparty credit ratings, transaction compliance and other relevant data. In addition, DME will provide periodic training to the PUB and Council on energy market fundamentals and commodity trading best practices to help facilitate more productive risk meetings. 4.2 Required Reports Minutes and meeting materials from quarterly RMC meetings will be distributed to the PUB and Council for their review. Minimum reporting requirements are listed below and are prepared for the RMC by the Middle Office and reviewed by both the Middle Office and Front Office. Controls Compliance Report Identifies any activities that have exceeded permissible limits. Hedge Target Compliance Report Provides an understanding of the status of portfolio exposure relative to program objectives and associated hedge targets. Competitiveness Report Provides a comparison of latest 12-month cost/mwh vs ERCOT spot markets (Day - Ahead and Real -Time Market) Renewable Resource Effective Cost Report Tracks the effective cost of each renewable resource, including the cost of market purchases when renewables output is insufficient to meet load. Price Risk Reduction Report Page 21 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy Measures the inherent market risk exposure over a given time horizon for DME's energy portfolio prior to market hedges and the residual market risk exposure after hedging. Credit Exposure Report Identifies the credit limit for each counterparty, current level of exposure with the counterparty, and remaining available credit. 4.3 Transaction Valuation DME's financial records will be maintained in full accordance with generally accepted accounting principles ("GAAP") and will be consistent with FERC Uniform System of Accounts. Front, Middle, and Back Office functions shall coordinate their efforts and maintain vigilance to ensure that DME's energy management transactions and risk exposures are accurately valued in an unbiased manner. Transaction valuation and reporting of positions shall be based on objective, market -observed prices or models. Open positions (i.e., whether DME needs to buy or sell energy on a daily, hourly, monthly or annual basis to balance customer loads against available resources) should be valued ("marked - to -market") daily, based on consistent valuation methods and data sources. Whenever possible, these valuations shall be based on independent, publicly available market information and data sources (e.g., Bloomberg, Reuters, NYMEX, ICE, broker quotes, etc.). The specification of position valuation methods is the responsibility of the Middle Office and is subject to RMC review. The Middle Office is responsible for obtaining and disseminating market information in a timely and consistent manner, along with maintaining and updating transaction data and information sources used for trade evaluation. The Middle Office is also responsible for assuring that data used for energy risk management calculations represent accurate and timely information available from reputable market or internal sources.

Energy Risk Management Policy SECTION 5 OTHER RESPONSIBILITIES AND POLICIES 5.1 Organization -Wide Responsibilities It is the policy of DME and the City of Denton that all personnel adhere to standards of integrity, ethics, conflicts of interest, compliance with statutory law and regulations and other applicable standards of personal conduct. The willful misrepresentation or concealment of information regarding portfolio management and/or risk management activities from senior management or any person responsible for the accurate tracking and reporting of such activities shall result in disciplinary action up to and including termination in accordance with DME and City of Denton policies and possible legal action as allowed or required by law. As an employee of the City of Denton, all DME personnel involved with its energy management activity should not have an expectation of privacy in the conduct of their duties. At any time, recorded phone calls and electronic transactions may be reviewed to ensure appropriate conduct or to review transactional information. 5.2 Commercial Interests and Trading for Personal Accounts All DME personnel who have any specific responsibilities delineated under this Policy or in the EMO Procedures Manual, are prohibited from engaging in the activities listed below: • Physical or financial trading of any commodities stipulated in this Policy or in supporting departmental procedures for their own account • Holding an undisclosed interest in any account or corporate entity (other than DME), which is used to trade the commodities described above. If there is any doubt as to whether a prohibited condition exists, then it is the employee's responsibility to disclose and discuss the possible prohibited condition with their supervisor. In addition, any employee receiving taxable income from any person or business doing business with DME must file a Conflicts Disclosure Statement in accordance with Chapter 176 of the Texas Local Government Code. Failure to comply with these requirements may result in disciplinary action up to and including immediate termination of employment, in accordance with DME and City of Denton policies.

Energy Risk Management Policy Appendix A PORTFOLIO RISKS As an electric utility, participation in physical and financial energy markets has the inherent potential to expose DME to the risks of cost and pricing uncertainty, revenue and commodity market volatility, and uncertainty in meeting budget targets. These risks may be broadly categorized into three risk categories: market, credit, and operational. Each category of risk is described below. The categories are not entirely separate: disruptions of planned operations, for instance, can expose a utility to the risk of having to enter into unforeseen transactions in adverse market conditions. The following section provides descriptions of the energy -related risks the Policy is intended to address. A.1. MARKET RISK DME manages energy purchases and sales with the goal of reducing the business risks associated with its obligation to serve energy to its ratepayers. These risks include volume -related and price - related risks. A.M. Price Risk Because of continual changes in the supply and demand for electricity, significant price changes can occur over a short time frame, otherwise known as price volatility. High price volatility means a high degree of uncertainty about the level of prices in the future. DME's price risk takes several forms, including: 1) exposure to changes in spot prices which DME faces in purchasing electric energy from the ERCOT market, 2) forward price risk of anticipated purchases or sales of power or fuel in the future and 3) the cost of energy - related products and services such as congestion revenue rights and ancillary services. Price risk also includes the basis risk associated with potential differences in the price of a commodity between geographic locations. For example, whenever DME must purchase power to satisfy native load requirements or is exposed to natural gas price uncertainty at various physical delivery points, DME is financially at risk due to the uncertainty in transmission or transportation costs between various locations. A.1.2. Volume Risk Volume Risk refers to uncertainty in the quantity of a commodity or service demanded, acquired, or supplied that has a potential economic impact. A primary volume risk for DME is the uncertainty associated with the amount of load DME will be required to serve. Page 25 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy Weather conditions affect customer energy usage, and weather changes make forecasting of load and non-dispatchable resources a challenge, causing actual quantities to deviate from forecasts. Forced or unexpected outages of generation resources also impact DME's volumetric risk. EMO Operating Procedures 1-4 contain details about DME's processes for developing forecasts of expected volumes associated with its portfolio of load and resources. A.M. Liquidity Risk DME transacts business in commodity markets that have inherent liquidity risk. Liquidity risk for DME arises when its intended transaction quantities exceed the size of current market bids (to buy) and offers (to sell). When DME desires to execute a transaction for a volume/quantity in excess of current market bids or offers, potential counterparties may be unwilling or unavailable to transact with DME. Transactions of nonstandard sizes and types also present liquidity risks. Liquidity risk should also be considered with regard to positions thought to be offsetting, but that may become open in the event that a counterparty defaults on their transaction responsibility (also referred to as "default risk"). It may be difficult to replace defaulted transactions on short notice. If a position must be covered quickly, the price of the necessary replacement transaction can be worse than if no urgency existed, especially if the potential counterparties know about the urgent need, putting DME as a significant disadvantage. A.2. CREDIT RISK DME is at risk if a customer, supplier or trading counterparty is unable or unwilling to fulfill its present or future contractual obligations to deliver power or fuel, or to make a timely payment of invoices or collateral. A.2.1 Credit Risk Credit Risk equals the potential replacement value of counterparty contractual obligations to deliver or receive power or fuel, or to make a timely payment to settle a financial contractual obligation. The potential financial impact from counterparty defaults is significant. DME's credit risk is addressed in a separate Credit Risk Management Policy. Page 26 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy A.2.2. Funding Risk Funding risk is related to credit risk. This term refers to the risk that DME might have to pay margin or post collateral to meet requirements to securitize its credit under credit provisions of Power Purchase Agreements, wholesale energy market, or to meet margin requirements for cleared contracts. A.3. OPERATIONAL RISK The term operational risk is often used as a catch-all category intended to include all risks that are not explicitly designated by other names, such as market risk, volume risk, liquidity risk, and credit risk. Operational risks include problems of several types that can have adverse financial consequences, and that relate to the operations of DME's energy portfolio, identification and control of risks, and processing and settlement of transactions. One such risk is Model Risk. A.3.1. MODEL RISK Model risk is a form of systems risk associated with unrecognized deficiencies of information systems used to in value transactions. A model may incorporate assumptions to derive unobservable pricing parameters from observable ones. There is a risk that a particular model used to value a transaction may not properly capture the value and risks of the transaction, and that its deficiencies may emerge only after the fact, following unfavorable market movements. A.4. REGULATORY RISK Regulatory risk is the uncertainty to DME's performance due to potential changes in laws or regulatory mandates. Examples include, but are not limited to, the following. A.4.1 Carbon Cost Unless explicitly borne by an energy supplier, DME is exposed to the potential risk of carbon costs. Any applicable law, rule, regulation, ordinance, protocol, order, decree, judgment or other similar legal mandate could cause DME to pay carbon costs associated with the production, generation, sale, metering, measurement, transmission, storage or delivery of electric energy. A.4.2 Changes to ERCOT market design The PUCT has directed ERCOT to study the impact of changes to its market design, which could have a significant impact on the flow of dollars between suppliers and consumers of power, possibly triggering the need to renegotiate long-term power contracts and changing the valuation of existing generation assets. Page 27 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy A.4.3 Ongoing changes to ERCOT Protocols The rules under which ERCOT operates are in a constant state of change. In fact, they change so often that ERCOT's governing board has a committee (Protocol Revisions Subcommittee) that meets monthly to review and process proposed changes submitted by ERCOT and its market participants. These changes usually impact how costs are allocated within ERCOT among market sectors, consumers and suppliers of power, and individual market participants like DME. AAA Regulatory Compliance Market Participants in the ERCOT region are subject to both state and federal laws and regulations. Market Participants that own or operate facilities that are part of the Bulk Electric System, as defined in federal law, are subject to oversight by the Federal Energy Regulatory Commission (FERC), the North American Electric Reliability Corporation (NERC), and Texas Reliability Entity, Inc. (Texas RE). Additionally, all ERCOT Market Participants are subject to oversight by the Public Utility Commission of Texas (PUCT). The PUCT administers the Public Utility Regulatory Act (PURA), and adopts and enforces rules pursuant to the authority granted in PURA. The PUCT also has oversight and enforcement authority over the ERCOT Protocols, Operating Guides, and Other Binding Documents. The PUCT has contracts with an Independent Market Monitor (16 T.A.C. §25.365) and a Reliability Monitor (16 T.A.C. §25.503) to assist with oversight and enforcement activities. Page 28 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy Appendix B RISK EXPOSURE AND TRANSACTION LIMITS DME's energy supply, trading and risk management -related activities shall be segregated among a number of "risk books." A risk book is a way of classifying and tracking positions and transactions that have similar or directly related purposes so that value and risk can be measured in sufficient detail to support both risk control and transaction strategy decisions. B.1 Risk Books System Book A System Book captures the value and risk position of native load obligations and long- term power and fuel supply obligations. Positions in the System Book will generally be of duration greater than one month or have a transaction start date of greater than one month into the future. Hedge Book The purpose of a Hedge Book is to track all positions that are entered into to reduce the total net risk exposure of the System Book. Hedge Book transactions should demonstrate their value (on a prospective basis) in mitigating the underlying source of risk to DME's native load, generation assets and long-term power and fuel supply obligations. Total Portfolio Book A Total Portfolio consists of the combination of all positions in the System Book and Hedge Book. B.2 Risk Exposure Limits An essential control element in the management of market risk is the development and adherence to an appropriate limit structure. A well -designed limit structure helps ensure DME does not assume greater aggregate risk than intended and helps ensure that risk taking at the transaction strategy level is appropriate at various levels of aggregation (e.g., by commodity, delivery period, strategy, etc.). The primary forms of limits listed below shall be applied to DME's energy management activity: Rates at Risk — Rates at Risk ("RaR") is a form of Cash Flow at Risk (CFaR) measurement. RaR limits will be set to limit the amount of uncertainty in future rates over the immediately upcoming 12-24 month period. If uncertainty in future rate requirements is higher than DME's risk tolerance, DME will consider hedging or implementing other risk management strategies to reduce the potential need for unforeseen rate increases and/or deterioration of DME's financial condition. Page 29 5/7/19 This document and any attachments thereto may contain information that is confidential, commercially -sensitive, proprietary, and/or public power utility competitive and financial information in accordance with the provisions of Texas Government Code, Section 552.101, 552.104, 552.110 and/or 552.133, and may be protected from required public disclosure. Energy Risk Management Policy Value at Risk —Value at Risk ("VaR") limits will be set to limit the potential loss in value of the portfolio. Notional/Volumetric —To augment RaR and VaR limits, notional limits and/or volumetric limits will be established. Notional limits are specified based on transaction or strategy dollar amount (i.e., contract or strategy volume x price). Volumetric limits are specified based on volume (e.g., MW, MWH, MMBTU, etc.). This provides a concrete limit to account for uncertainties in risk measurement and human judgment capabilities. Other volumetric limits may be established in relation to specific risks not captured by RaR or VaR. ERCOT— Implementation of the ERCOT Real Time Market (RTM) and Day Ahead Markets (DAM) require daily attention to Available Credit Limits (ACL) and forward liability calculations. The Back Office shall actively monitor and communicate any changes affecting current credit positions. Stop Loss —Stop loss limits are set, such that, if an individual position or strategy (or a hedge transaction or strategy which has become ineffective) is performing adversely and approaches a predetermined level of losses, the position or strategy must be liquidated or completely hedged to prevent further loss. B.3 Portfolio Risk Exposure Limits Because ERCOT is responsible for ensuring physical reliability of the grid, DME's efforts focus primarily on managing the rate impact of price volatility risk of its portfolio. For the purposes of managing this risk, DME will assume an average consumer risk tolerance (CRT) equivalent to 1 cent per kwh of load over a rolling 12-month period. Hedging is DME's primary method for reducing market price volatility risk, either by locking in or limiting the amount of variation of a future market price. The "downside" of hedging is that it not only reduces the chances of incurring higher costs than expected, it also reduces the chances of lower than expected energy costs, and correspondingly lower electric rates. DME uses an "at Risk"' methodology to estimate, at a 95% confidence level, the amount of an electric rate increase that could occur due to changes in market conditions such as volumetric z The "at Risk" metric DME will use is based on a "Rates at Risk" (RaR) methodology, which refers to the statistical dollar amount that can be lost on the net open position of a portfolio over a specific time horizon and with a given confidence interval. DME's RaR methodology accounts for the increasing potential distribution of prices as time passes, as well as the expiration of the positions in the portfolio with the passage of time. The result is the estimation of loss, at the specified confidence level, assuming that the portfolio remains constant over time until all positions within it have expired.

Energy Risk Management Policy risk associated with its renewable resources, ERCOT day -ahead and real time market price volatility, gas price volatility, nodal price congestion, price correlations and credit risk. If DME's estimate of a rate increase, at a 95% confidence level, exceeds the CRT threshold by 25%, DME will meet and confer with the RMC, and with the City Council and PUB as noted in the table below, to discuss alternatives for implementing additional hedging strategies to bring the level of possible price volatility back inside the CRT threshold. No particular portfolio action is required, making this notification requirement very different from a trading limit. "At Risk" limits for the total portfolio are: RMC Notification Council / PUB Notification Rolling 12 months (in aggregate) $15.0 million $19.0 million BA Open Position Management DME's primary objective is to protect against risks inherent in its portfolio, such as exposure to price volatility and from variability in supply and demand. DME plans to execute hedging transactions relatively evenly over time, to diversify timing risk (similar to dollar cost averaging), and does not speculate3 . Market transactions shall be executed as a result of strategies designed to maintain the net open position (the gap between expected demand and committed supply) within tolerances which are consistent with current hedging strategies. The resultant net open position shall be updated to reflect the new transactions as soon as practical, but generally no later than the next business day. Net open position energy tolerances shall be set at the following, on a total MWH basis either by time of use (TOU) period (through Balance of Year)' or on an annual basis (for prompt Calendar Year and beyond): 3 The US Commodity Futures Trading Commission defines a speculator as "a trader who does not hedge, but who trades with the objective of achieving profits through the successful anticipation of price movements" (CFTC Glossary: A guide to the language of the futures industry). 4 Within the ERCOT region, through at least the balance of year, DME's open position can generally be managed by three time of use periods; Peak Weekday (weekdays HE 7-22), Peak Weekend (weekends and holidays HE 7-22) and Nights (HE 1-6, 23-24).

However, in the event that it does, DME shall evaluate alternatives to flatten the net open position (whether long or short) and will inform the RMC of any exceedance expectations for annual periods. B.5 Transaction Limits Another vital control element in the management of energy risk is the development and adherence to transaction limits. Transaction limits ensure the energy portfolio management function is prudent, deliberate and controlled at various levels of position aggregation and transaction duration. Transaction limits are established in consideration of overall portfolio strategies, market conditions and risk tolerance levels and include the following principles: 5 A net "short" open position represents DME needing to buy additional energy to match its forecasted load requirements during a given time period. 6 A net "long" open position represents DME having an obligation to accept more energy than needed to match its forecasted load requirements during a given time period.

Energy Risk Management Policy ■ DME personnel involved with its energy management activity are authorized to execute any intra-day or day -ahead transaction which is necessary to mitigate market and financial risk exposure to DME customers. ■ Speculative transactions are those transactions not intended for hedging purposes and are strictly prohibited. All transactions shall either reduce risks or be risk -neutral to DME customers. ■ No transaction may be executed for which DME does not have adequate systems or analytical methods to track, record, value, or analyze the incremental cash flow and risk. ■ Any single transaction for a term greater than one year must be approved by the RMC prior to execution. ■ Scheduling of loads and resources, along with corresponding bid or offer prices associated with ERCOT Day Ahead Market (DAM), ERCOT Real Time Market (RTM) or ERCOT Supplementary Ancillary Services (SASM) Market are not subject to this Risk Policy or to the limits outlined below and do not require prior RMC approval. All executed transactions must be recorded and captured in DME's system of record. Further, all transactions shall be conducted on recorded phone lines, electronic trading platforms, or other media that can be recorded and documented. Any confirmations received must be signed by the person with the authority to enter into such transaction. Confirmations for transactions with ERCOT are evidenced through the ERCOT Settlement Summary statement. The following tables outline the transaction authorization limits established for DME personnel involved with its energy management activity when executing transactions. Those personnel are permitted to execute transactions less than or equal to their designated limits or under the direction of someone having the required authority. Only the Approved Transaction Types listed in Appendix D may be executed unless otherwise approved by the RMC.

A copy of the current CRR Activity Calendar which shows key dates associated with each Monthly and Annual CRR auction at http://ercot.com/mktinfo/crr • Monthly CRR auctions end about 2 weeks before the CRR effective start date • Conventional Resource Nodes include Denton Energy Center, Gibbons Creek, White Tail & Santa Rita Wind Farms, Blue Bell Solar Farm and resource nodes or ERCOT Hubs associated with fully executed PPAs • Primary ERCOT Hub is "North Hub" • Primary ERCOT Load Zone is "Load Zone North" • The purchase of CRRs for each Source/Sink pair from all ERCOT auctions is limited to the nameplate rating of the generator for City -owned resources or the contract capacity rating for PPAs. A Congestion Revenue Right (CRR) is a financial instrument that results in a charge or a payment to the owner, when the ERCOT transmission grid is congested in the Day Ahead Market (DAM). DME uses CRRs as a financial hedge to lock in the price of congestion at the purchase price of the CRR. DME also hedges congestion in ERCOT's Real -Time market by buying CRR-like instruments called Point to Point (PTP) Obligations. The main purposes of the ERCOT CRR market are to: • Support a liquid energy market by providing tradable financial instruments for the hedging of transmission congestion charges • Allow market participants to eliminate or greatly reduce the cost uncertainties resulting from transmission congestion charges • Encourage competitive energy trading, where the costs of congestion might otherwise be an impediment DME's primary objective for hedging congestion risk is to mitigate potentially adverse financial consequences from uncertain price differences caused by transmission congestion between the location where it consumes power (ERCOT LZ_North), the locations where it purchases power on a forward basis (EROTT North Hub), and the ERCOT nodes associated with its resources (Denton Energy Center, Gibbons Creek, White Tail & Santa Rita Wind farms, Blue Bell solar farm and future renewable resources). DME is exposed to transmission congestion risk for all amounts of energy forecasted to be consumed in the ERCOT North Load Zone, and energy that could potentially be produced at their respective resource nodes. By default, ERCOT charges all DME load for energy, along with any congestion, in the Real Time Market ("RT"). DME mitigates congestion risk with congestion hedges using Congestion Revenue Rights (CRRs).

The North Hub is also used as a delivery point for bilateral trades (for liquidity purposes) Consistent with DME's approach to hedging energy, DME seeks to acquire CRRs at steadily increasing amounts roughly corresponding to Auction Capacity Percentages, to diversify timing risk, similar to dollar cost averaging, and does not use event -driven trading to time the market, trading in and out of positions. DME employs a tiered approach in ERCOT's annual and monthly auctions".

Energy Risk Management Policy Appendix E FORWARD HEDGING STRATEGIES AND PLANS Successful management of the price and volumetric risks faced by DME requires analysis, monitoring, and communication. Analysis of published weather forecasts and market price data serve as key inputs to models used for planning and ensures that the appropriate data is converted into useful information. Consistent with market risk policies defined herein and the risk limits defined in Appendix A, DME, in concert with the RMC, develops annual hedging strategies with underlying hedging plans as a means to manage the volumetric and price risks faced by the utility. A review of the status of current hedging plans will typically be a topic of discussion at RMC meetings. Prior to February 1 of each year, DME shall submit a written Hedging Strategy for managing its expected net open position for the upcoming three (3) full calendar years. Due to the complexity of the wholesale energy markets and the energy regulatory environment, the Hedging Strategy is expected to require several Hedging Plans to be developed and approved during each year. The RMC will approve the Hedging Strategy by the end of February each year or at its first meeting thereafter. Each Hedging Plan will: • Cover a clearly specified forward time period; • Explain the justification for the hedge (a general description of the resource mix and load that contribute to the open position for the specified time period, along with the Open Position tolerances for the specified forward time period); • Define a volumetric limit for hedge purchases and sales; • Document transaction types expected to be used to carry out the Hedging Plan; and • Proposed price triggers that will enable hedging activity within the Hedging Plan's limits. DME may, at any time, request that the RMC consider changes to the current Hedging Strategy or to an individual Hedging Plan. Any approved changes to the Hedging Strategy or Hedging Plan shall be recorded in the RMC meeting minutes and an updated written Hedging Strategy or Hedging Plan document will be prepared as soon as practical incorporating such changes. On occasion, it will become apparent to DME management that additional transactions to reshape expected monthly forward positions are necessary given changes in generation forecasts, market conditions, and load forecasts. The DME General Manager may direct EMO staff to enter into and execute such transactions to rebalance the forward position. These transactions will be discussed in RMC meetings ahead of time if conditions allow, or reported after the fact and documented in the minutes of the next RMC meeting.
