SCHEDULE J, PART I, LINE 1A TAX INDEMNIFICATION AND GROSS-UP PAYMENTS	DURING 2025, ONE OF ISO NEW ENGLAND'S KEY EMPLOYEES AND TWO FIVE HIGHEST PAID EMPLOYEES RECEIVED AWARDS UNDER THE COMPANY'S EMPLOYEE RECOGNITION PROGRAM. THE TAXABLE EMPLOYEE RECOGNITION PROGRAM IS AVAILABLE TO ALL EMPLOYEES WITH EXCEPTION OF THE CEO, EXECUTIVE/SENIOR VICE PRESIDENTS, AND VICE PRESIDENTS. THE EMPLOYEE RECOGNITION PROGRAM RECOGNIZES EMPLOYEE ACHIEVEMENTS OR ACCOMPLISHMENTS THAT CONTRIBUTE TO THE OVERALL OBJECTIVE OF THE BUSINESS. IT ENCOURAGES EMPLOYEES TO EXCEL IN ISO CORE COMPETENCIES, EITHER INDIVIDUALLY OR THROUGH TEAMS. THE KEY EMPLOYEE AWARD HAD AN AFTER-TAX VALUE OF $150 AND A RELATED $12 TAX GROSS UP. THE FIVE HIGHEST PAID EMPLOYEES AWARDS HAD AN AFTER-TAX VALUE OF $1,000 AND $150 AND RELATED $415 AND $63 TAX GROSS UPS, RESPECTIVELY.
SCHEDULE J, PART I, LINE 3 ARRANGEMENT USED TO ESTABLISH THE TOP MANAGEMENT OFFICIAL'S COMPENSATION	COMPENSATION IS APPROVED IN ADVANCE BY THE BOARD OF DIRECTORS (THE "BOARD"). SCHEDULE O, FORM 990, PART VI, SECTION B, LINE 15 PROVIDES A COMPLETE DESCRIPTION OF THE ESTABLISHMENT OF COMPENSATION FOR ISO NEW ENGLAND'S CHIEF EXECUTIVE OFFICER, AND OTHER OFFICERS OF THE COMPANY.
SCHEDULE J, PART I, LINE 4A SEVERANCE OR CHANGE-OF-CONTROL PAYMENT	GORDON VAN WELIE LEFT THE COMPANY AT THE END OF 2025. COMPENSATION PAYMENTS RELATED TO VAN WELIE'S RETIREMENT AND SEPARATION FROM THE COMPANY AS REPORTED ON THE ISO'S 2025 FORM 990 REFLECT OBLIGATIONS UNDER PRE-EXISTING SEVERANCE POLICIES AND EMPLOYMENT AGREEMENTS, ALONG WITH CERTAIN NEGOTIATED AMOUNTS. A PORTION OF THESE PAYMENTS IS DEFERRED TO YEARS 2026 AND 2027 AND SUBJECT TO CANCELLATION SHOULD VAN WELIE BECOME EMPLOYED IN A SIMILAR EXECUTIVE POSITION. THESE PAYMENTS ARE REPORTED ON THE FORM AS "DEFERRED COMPENSATION WILL ALSO BE REPORTED AS COMPENSATION IN THE YEAR THEY ARE PAID. ALBERT EVANS RECEIVED SEVERANCE PAYMENT IN THE AMOUNT OF $75,000.
SCHEDULE J, PART I, LINE 7 NON-FIXED PAYMENTS	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 DEFERRED PERFORMANCE INCENTIVE PLAN (THE "DPI 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 DPI PLAN AWARDS ARE AVAILABLE TO OFFICERS 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 DPI 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, DPI 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 DPI 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.
