        <ExplanationTxt>ATP IS EXEMPT FROM INCOME TAXES ON INCOME FROM RELATED ACTIVITIES UNDER SECTION 501(C)(6) OF THE U.S. INTERNAL REVENUE CODE AND CORRESPONDING STATE TAX LAW. CERTAIN OF ITS ACTIVITIES ARE SUBJECT TO TAX ON NET UNRELATED BUSINESS INCOME FROM THOSE ACTIVITIES. ATP IS NOT CONSIDERED TO BE A PRIVATE FOUNDATION UNDER SECTION 509(A) OF THE INTERNAL REVENUE CODE. THE ORGANIZATION HAS ADOPTED APPLICABLE GUIDANCE WITH RESPECT TO ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES. A TAX POSITION IS RECOGNIZED AS A BENEFIT ONLY IF IT IS "MORE LIKELY THAN NOT" THAT THE TAX POSITION WOULD BE SUSTAINED IN A TAX EXAMINATION, WITH A TAX EXAMINATION BEING PRESUMED TO OCCUR. THE AMOUNT RECOGNIZED IS THE LARGEST AMOUNT OF TAX BENEFIT THAT IS GREATER THAN 50% LIKELY OF BEING REALIZED ON EXAMINATION. FOR TAX POSITIONS NOT MEETING THE "MORE LIKELY THAN NOT" TEST, NO TAX BENEFIT WILL BE RECORDED. THE ORGANIZATION DOES NOT EXPECT THE TOTAL AMOUNT OF UNRECORDED TAX BENEFITS TO SIGNIFICANTLY CHANGE IN THE NEXT 12 MONTHS. THE ORGANIZATION RECOGNIZES INTEREST AND/OR PENALTIES RELATED TO INCOME TAX MATTERS IN INCOME TAX EXPENSE. THE ORGANIZATION DID NOT HAVE ANY AMOUNTS ACCRUED FOR INTEREST AND PENALTIES AT DECEMBER 31, 2024 AND 2023.</ExplanationTxt>
