        <ExplanationTxt>THE INTERNAL REVENUE SERVICE HAS CLASSIFIED THE CENTER AS EXEMPT FROM FEDERAL INCOME TAXES UNDER SECTION 501(C)(3) OF THE INTERNAL REVENUE CODE ("CODE"). IN ADDITION, THE CENTER QUALIFIES FOR THE CHARITABLE CONTRIBUTION DEDUCTION UNDER SECTION 170(B)(1)(A) OF THE CODE AND HAS BEEN CLASSIFIED AS AN ORGANIZATION OTHER THAN A PRIVATE FOUNDATION UNDER SECTION 509(A)(1) OF THE CODE. U.S. GAAP REQUIRES MANAGEMENT TO EVALUATE TAX POSITIONS TAKEN AND RECOGNIZE A TAX LIABILITY IF THE CENTER HAS TAKEN AN UNCERTAIN TAX POSITION THAT MORE LIKELY THAN NOT WOULD NOT BE SUSTAINED UPON EXAMINATION BY A GOVERNMENT AUTHORITY. MANAGEMENT HAS ANALYZED THE TAX POSITIONS TAKEN BY THE CENTER AND HAS CONCLUDED THAT AS OF JUNE 30, 2025 AND 2024, THERE ARE NO UNCERTAIN POSITIONS TAKEN OR EXPECTED TO BE TAKEN THAT WOULD REQUIRE RECOGNITION OF A LIABILITY OR DISCLOSURE IN THE FINANCIAL STATEMENTS. THE CENTER RECOGNIZES ACCRUED INTEREST AND PENALTIES ASSOCIATED WITH UNCERTAIN TAX POSITIONS, IF ANY. THERE WERE NO INCOME TAX RELATED INTEREST OR PENALTIES RECORDED FOR EITHER OF THE YEARS ENDED JUNE 30, 2025 OR 2024.</ExplanationTxt>
