FORM 990, PART VI, SECTION A, LINE 6	THE ORGANIZATION HAS ONE CLASS WITH 9 MEMBERS.
FORM 990, PART VI, SECTION B, LINE 11B	THE ORGANIZATION'S CONTROLLER PERFORMS A DETAILED REVIEW OF THE FORM 990 AFTER IT IS PREPARED BY AN INDEPENDENT CPA FIRM. A COPY OF THE FORM IS PROVIDED BY EMAIL TO ALL BOARD MEMBERS FOR REVIEW PRIOR TO FILING. THE ORGANIZATION'S VP OF FINANCE THEN PERFORMS A FINAL REVIEW BEFORE SIGNING THE 990.
FORM 990, PART VI, SECTION B, LINE 12C	THE BOARD REVIEWS AND RESOLVES, IF NECESSARY, ANY ISSUES AS THEY ARISE THROUGHOUT THE YEAR. A CONFLICT OF INTEREST QUESTIONNAIRE IS COMPLETED BY EACH BOARD MEMBER ANNUALLY. IF A CONFLICT ARISES, THE ORGANIZATION'S PRESIDENT DISCUSSES THE ISSUE WITH THE BOARD CHAIR.
FORM 990, PART VI, SECTION B, LINES 15A & 15B	COMPENSATION FOR THE PRESIDENT AND CEO IS APPROVED BY THE BOARD OF DIRECTORS ANNUALLY BASED UPON COMPARABILITY DATA OBTAINED FROM AN INDEPENDENT THIRD PARTY. COMPENSATION FOR ALL OTHER POSITIONS IS APPROVED ANNUALLY BY THE PRESIDENT AND CEO BASED UPON COMPARABILITY DATA OBTAINED FROM COMPENSATION SURVEYS FROM AN INDEPENDENT THIRD PARTY. THE TOTAL ANNUAL COMPENSATION BUDGET IS ACCEPTED BY THE COMPENSATION AND BENEFITS COMMITTEE, FINANCE AND AUDIT COMMITTEE, AND IS RATIFIED BY THE BOARD OF DIRECTORS. THE ORGANIZATION'S MOST RECENT REVIEW WAS CONDUCTED DURING 2020 BY WILLIS TOWERS WATSON.
FORM 990, PART VI, SECTION C, LINE 19	THE ORGANIZATION MAKES ITS GOVERNING DOCUMENTS, CONFLICT OF INTEREST POLICY, AND FINANCIAL STATEMENTS AVAILABLE TO THE PUBLIC UPON REQUEST. THE AUDITED FINANCIAL STATEMENTS ARE AVAILABLE ON THE GUIDESTAR WEBSITE AS WELL.
FORM 990, PART XI, LINE 9	OTHER CHANGES IN NET ASSETS BUYBACK OF UNRESTRICTED PATRONS' EQUITY $ (2,500,000) CHANGE IN FV OF INTEREST RATE SWAP $ (349,934) ------------ $ (2,849,934)
BOARD OF DIRECTORS RELATED COMPENSATION	THE ORGANIZATION OPERATES A CENTRAL HEATING AND COOLING SERVICE FACILITY SOLELY FOR THE BENEFIT OF GOVERNMENTAL INSTITUTIONS AND NOT-FOR-PROFIT ENTITIES IN THE TEXAS MEDICAL CENTER. THE ORGANIZATION IS ORGANIZED AS A SUPPORT ORGANIZATION PROVIDING SUPPORT IN THE FORM OF HEATING AND COOLING SERVICES TO QUALIFYING ENTITIES. AS SUCH, NINE OF THE PARTICIPATING/SUPPORTED ORGANIZATIONS ARE REPRESENTED ON THE GOVERNING BODY OF THE ORGANIZATION VIA BOARD MEMBERSHIP. EACH OF THE NINE ORGANIZATIONS APPOINTS A DIRECTOR TO SIT ON THE GOVERNING BOARD OF THE ORGANIZATION. MEMBERS OF THE GOVERNING BODY ARE NOT COMPENSATED FOR THEIR SERVICES TO THE ORGANIZATION. COMPENSATION EARNED BY MEMBERS OF THE GOVERNING BODY FROM THEIR RESPECTIVE SUPPORTED ORGANIZATION IS FOR SERVICES IN THEIR CAPACITY AS AN EMPLOYEE OF THE SUPPORTED ORGANIZATION AND IS NOT IN ANY WAY TIED TO THE SERVICES OR OPERATIONS OF THE ORGANIZATION. BASED ON THE INSTRUCTIONS TO FORM 990, THE SUPPORTING/SUPPORTED RELATIONSHIP MEETS THE DEFINITION OF A RELATED ENTITY FOR PURPOSES OF COMPENSATION AND OTHER REPORTING ITEMS. WHILE THE ORGANIZATION DOES NOT FEEL THE SUPPORTED ORGANIZATIONS ARE RELATED UNDER THE INTENT OF THE IRS DISCLOSURE RULES, THE SUPPORTED ORGANIZATIONS DO QUALIFY AS RELATED BASED ON THE LITERAL READING OF THE INSTRUCTIONS. ACCORDINGLY, THE ORGANIZATION HAS MADE REASONABLE EFFORTS TO OBTAIN COMPENSATION INFORMATION FROM BOARD MEMBERS WHO ARE EMPLOYED BY THEIR RESPECTIVE SUPPORTED ORGANIZATIONS. IN ADDITION, THE COMPENSATION TO MEMBERS OF THE GOVERNING BODY RECEIVED IN THEIR CAPACITY AS AN EMPLOYEE OF THE SUPPORTED ORGANIZATION CREATES AN INDEPENDENCE ISSUE FOR PURPOSES OF ANSWERING PART VI, QUESTION 1B. WHILE THE ORGANIZATION STRONGLY FEELS ALL MEMBERS OF THE GOVERNING BODY ARE INDEPENDENT BASED ON THE FACTS AND CIRCUMSTANCES, A LITERAL READING OF THE IRS DEFINITION OF AN INDEPENDENT BOARD MEMBER CAUSES THE ORGANIZATION TO ONLY INCLUDE BOARD MEMBERS WHO ARE NOT COMPENSATED BY THEIR RESPECTIVE SUPPORTED ORGANIZATION. AGAIN, THE ORGANIZATION BELIEVES THIS RESULT IS NOT WHAT THE IRS INTENDED, BUT IN AN EFFORT TO COMPLY WITH THE INSTRUCTIONS, THE ORGANIZATION HAS REPORTED THE NUMBER OF INDEPENDENT BOARD MEMBERS BASED ON A LITERAL READING OF THE IRS INSTRUCTIONS.
