Desc	Reference Line 4a: Energy Administration - ISO New England Inc. (ISO-NE) is the not-for-profit organization authorized by the federal government to perform three critical activities to ensure the reliable and safe supply of electricity throughout New England. Through its first activity, Energy Administration, ISO-NE ensures the constant availability of competitively-priced electricity for the region's 14.8 million residents by designing, refining, and administering the region's wholesale electricity markets and making sure these markets are fair and competitive. During 2020, ISO-NE was responsible for the fair administration of over $5.72 billion dollars of market transactions.	Desc

Desc	Reference Line 4b: Reliability Administration - Through its second activity, Reliability Administration, ISO-NE ensures the reliable day-to-day operation of the region's high voltage transmission system. Among other things, this involves (i) coordinating the region's 350 power plants and 9,000 miles of high voltage transmission lines; (ii) managing the movement of high-voltage electricity into, within, and out of New England; (iii) ensuring that the six-state region has the power system resources necessary to meet consumer demand for electricity and federally-mandated reliability requirements; (iv) coordinating how transmission lines, power plants (such as coal, oil, nuclear, and natural gas-fired), and other resources connect to and operate on the power grid reliably; and (v), working with the industry to develop transmission infrastructure solutions that are essential for maintaining power system reliability. During 2020, ISO-NE coordinated the generation and transmission of the 116,864 gigawatt-hours of power consumed in the region.	Desc

Desc	Reference Line 4c: Scheduling Service - Through its third activity, Scheduling Services, ISO-NE forecasts and schedules the electricity needed in the region for every second of every day and ensures there is enough electricity generated to meet demand and resources needed to maintain stringent reliability criteria. In conducting this activity, ISO-NE (i) monitors the flow of electricity into, out of, and over New England's high-voltage transmission system and (ii) schedules hundreds of diverse power resources and transmission components to supply just the right amount of electricity to meet the region's demand, which changes every time someone flips a switch. If too little electricity is produced, lights may not come on. Too much electricity could damage the system. ISO-NE is responsible for ensuring that the grid can withstand the sudden loss of a power plant or transmission equipment caused by weather, mechanical failure, terrorism, or other triggers.	Desc

Schedule J, Part I, Line 1a	During 2020, one of the Corporation's Five Highest Compensated Employees (that was not also a current officer, director, trustee, or key employee) received a personal services benefit and a related tax indemnification and gross up benefit. The benefits were approved by the Board of Directors. The value of the benefits received during 2020 were included on the employee's IRS Form W-2 for 2020 as taxable compensation. In addition, during 2020 ISO New England paid one Key Employee, and one Five Highest Compensated Employee a total of $885 for wellness program rewards. These two employees were also compensated a total of $260 for tax gross-up of the wellness program rewards. The wellness program rewards and related tax gross-up payments are available to all ISO New England employees who register for and successfully complete offered wellness programs.
Schedule J, Part I, Line 4	Michael Henderson received a severance payment in the amount of $194,190.
Schedule J, Part I, Line 7	ISO New England currently administers two incentive compensation plans that both provide for non-fixed payments: an annual performance incentive plan (the "API Plan") and a long-term incentive plan (the "LTI Plan"). Subject to certain eligibility criteria, most employees may receive an API Plan award based upon a formula that takes into account organizational performance, individual performance, annual base pay (as December 31st of the plan year) and a grade-related salary percentage. Organizational performance is measured by the Board of Directors of ISO New England (the "Board") against goals and objectives developed by the Compensation and Human Resources Committee of the Board (the "Committee"), other Board committees, and the Board at the commencement of each plan year. The individual performance of an officer is evaluated by the Committee and the Board. The final API Plan award for an officer is calculated and paid once the Board determines the scores for organizational performance and individual performance for the plan year. The LTI Plan awards are available to officers and certain other employees and are based upon the achievement of organizational and individual long-term goals established by recommendations of the Committee (with input from other Board committees) and with the approval of the Board. Similar to the API Plan, the LTI Plan awards are calculated using an eligible employee's base salary in effect as of December 31st of the plan year and a grade-related salary percentage; however, LTI Plan awards generally are paid two and one-half years after the end of the plan year. The Board assesses the performance of the organization and the individual at the end of each plan year, and reassesses the organization's progress towards its long-term goals and objectives two and one-half years later, immediately prior to the calculation and pay-out of the LTI Plan award. Under both plans, ISO New England reserves the right to reduce or eliminate plan awards if the eligible employee or the organization underperforms or there is a major collapse of the bulk electric power system managed by ISO New England.

Form 990, Part VI, Section A, Line 6	ISO New England Inc. is governed by a ten-person Board of Directors. Nine of the individuals on the Board of Directors are independent voting directors, and act also as voting members of ISO New England Inc. (The tenth individual on the Board of Directors is the President and Chief Executive Officer of ISO New England Inc.; he is a non-voting director and is not a member of ISO New England Inc.). The voting members of ISO New England Inc. and the Board of Directors of ISO New England Inc. have no financial interest in any company doing business in New England's electricity markets and are elected to their positions because of their expertise in financial markets, law, and/or electric power operations and regulation.
Form 990, Part VI, Section A, Line 7a	Members of the Board of Directors are elected by the current voting directors of the Board in their capacity as members of ISO New England Inc. They are nominated by the Nominating and Governance Committee of the Board of Directors, which is a standing committee consisting of three or more members of the Board of Directors of the Company. Each member of the Committee must meet all independence standards imposed under the Company's charter, by-laws and code of conduct, as well as any other applicable independence standards adopted by the Board of Directors. Before the formal nomination and election, a joint nominating committee composed of stakeholders and members of the Board develops the slate of candidates for election.
Form 990, Part VI, Section B, Line 11b	The Form 990 is prepared by the Lead Financial Analyst and then reviewed and commented upon by the Supervisor, Budget and Financial Reporting. The Form 990 is then reviewed and commented upon by the Director, Finance & Accounting, and then by ISO New England's external tax counsel, Chief Financial and Compliance Officer and then reviewed by the Audit & Finance Committee of the Board of Directors and then by ISO New England's full Board of Directors prior to being filed.
Form 990, Part VI, Section B, Line 12c	ISO New England has a "Code of Conduct" that applies to its directors and employees (including officers and key employees). The Audit and Finance Committee of the Board of Directors oversees the administration of the Code of Conduct and ensures that prompt action is taken to investigate any potential violations of, or noncompliance with, the Code of Conduct. When a member of the Board of Directors is involved, the full Board makes the relevant determination. On behalf of the Audit and Finance Committee, the Compliance Officer, who is the Vice President, Human Resources, has the day-to-day responsibility for reviewing compliance with the Code of Conduct, including interpreting the Code of Conduct, advising directors, officers and employees regarding potential conflicts of interest and following up on all suspected violations. Individuals subject to the Code of Conduct are prohibited from using their positions to improperly benefit themselves, their family members or the people with whom they cohabitate. Similarly, such individuals are prohibited from having a significant financial interest in any contractor, company, business, or enterprise which has, or is seeking to establish, business relations with ISO New England Inc., unless that relationship has been disclosed to the Compliance Officer or his or her designee and approved by the Audit and Finance Committee of the Board of Directors. Individuals subject to the Code of Conduct are obligated to identify activities of another director, officer or employee that do not comply with the Code of Conduct and report them to the Compliance Officer. Such reports may be made on a confidential basis and individuals will not be subject to retaliatory actions for making such reports. Individuals who violate the Code of Conduct may be subject to disciplinary action including suspension from duties or termination. All directors and employees are required to sign an annual compliance certificate that states, among other things, that the individual has read, fully understands and will comply with the Code of Conduct.
Form 990, Part VI, Section B, Line 15	The compensation of the chief executive officer and of each of the other senior executive officers of ISO New England Inc. (the "Company") is determined in a manner so that the total compensation of each individual is presumed to be reasonable in accordance with Treasury Regulation § 53.4958-6. In accordance with this Treasury Regulation: (i) each compensation arrangement is approved in advance by the members of the Board of Directors (the "Board") and/or of the Compensation and Human Resources Committee of the Board (the "Committee") who do not have a conflict of interest with respect to that compensation arrangement (as set forth in Treas. Reg. § 53.4958-6(c)(1)(iii)); (ii) each of the Board and the Committee obtains and relies upon appropriate data as to comparability prior to making its determination regarding a compensation arrangement; and (iii) the basis for the compensation-related determination made by the Board or the Committee is adequately documented concurrently with the making of the determination. The Company's overall compensation policy is designed to promote the tax-exempt purposes of the Company by attracting, retaining and motivating highly-skilled senior management to deliver superior service in furtherance of the Company's exempt purpose: to lessen the burdens on government through the administration of an efficient and reliable electricity transmission system, wholesale electricity marketplace and comprehensive regional bulk power system planning process for the benefit of New England. For each fiscal year, the Committee develops recommendations regarding: (i) the base salary of each senior executive; (ii) the annual performance incentive plan (i.e. the short-term incentive compensation plan) goals and objectives for the plan year for the Company and each senior executive; (iii) the long-term incentive compensation plan goals and objectives for the plan year for the Company and each senior executive; and (iv) proposed changes, if any, to the Company's fringe benefit plans. At the end of each fiscal year, the Committee also makes recommendations regarding the performance of the Company and each senior executive against the plan year goals and objectives established under both the short-term incentive compensation plan and the long-term incentive compensation plan. All of the aforementioned Committee recommendations are based upon information and materials derived from a number of sources, including: evaluations of the Company's performance, requirements and short- and long-range strategic plans as prepared by the Board, Board committees and senior executives; evaluations of the performance of each senior executive's performance as prepared by the Board, the Committee and/or senior executives; salary and other compensation surveys conducted by independent human resources and compensation consulting firms; reports and findings prepared by an independent human resources and compensation consulting firm retained by the Company to evaluate the reasonableness of the compensation paid to senior executives; and written and anecdotal information collected by the Human Resources Department of the Company in connection with the recruitment and retention of senior executives for the Company (including reports provided by executive recruitment firms). The compensation-related recommendations made by the Committee are referred to the Board for its review, together with all evaluations, surveys, consultant reports and findings and other information compiled by the Committee. The Board reviews the recommendations and material provided by the Committee, and considers the recommendations in light of: the performance, financial condition, requirements, and exempt purpose goals and objectives of the Company; the performance, experience, and responsibilities of each senior executive; and the competitive market for executive talent. The recommendations also are weighed against a range of reasonable compensation established for each of the Company's executives by an independent human resources and compensation consulting firm (in 2020, Mercer), based upon independent survey sources and compensation information for functionally-comparable positions provided or made available by other regional transmission operators, independent systems operators, and other similarly situated taxable and tax-exempt organizations. Based on the foregoing, the Board makes a final decision regarding each of the elements of each senior executive's compensation, including: base salary; the current fiscal year's goals and objectives for each of the Company and the executive for each of the short-term incentive compensation plan and the long-term incentive compensation plan; changes (if any) to the Company's fringe benefit plans; the performance scores against the prior fiscal year's goals and objectives for each of the Company and the executive for each of the short-term incentive compensation plan and the long-term incentive compensation plan; and the final payments to be made in the current fiscal year under the Company's incentive compensation plans based upon those Company and individual performance scores. Each compensation-related decision of the Board is documented in the minutes of the meeting or meetings at which that decision is made including the materials and information relied upon to make the decision, the identity of the members of the Board making the decision and a summary of the Board's deliberations and reasons underlying the decision. Those minutes are thereafter reviewed and, with any corrections agreed to by the Board, are approved at the next monthly meeting of the Board.
