        <ExplanationTxt>THE SCHOOL IS EXEMPT FROM INCOME TAXES UNDER INTERNAL REVENUE CODE SECTION 501 (C)(3). IT IS NOT A PRIVATE FOUNDATION. THE CASH BASIS OF ACCOUNTING REQUIRES MANAGEMENT TO EVALUATE TAX POSITIONS TAKEN BY THE SCHOOL AND RECOGNIZE A TAX LIABILITY (OR ASSET) IF THE SCHOOL HAS TAKEN AN UNCERTAIN POSITION THAT MORE LIKELY THAN NOT WOULD NOT BE SUSTAINED UPON EXAMINATION BY THE INTERNAL REVENUE SERVICE. SCHOOL MANAGEMENT HAS ANALYZED THE TAX POSITIONS TAKEN BY THE ORGANIZATION, AND HAS CONCLUDED THAT AS OF DECEMBER 31, 2021, THERE ARE NO UNCERTAIN POSITIONS TAKEN OR EXPECTED TO BE TAKEN THAT WOULD REQUIRE RECOGNITION OF A LIABILITY (OR ASSET) OR DISCLOSURE IN THE FINANCIAL STATEMENTS. THE SCHOOL IS SUBJECT TO ROUTINE AUDITS BY TAXING JURISDICTIONS; HOWEVER, THERE ARE CURRENTLY NO AUDITS FOR ANY TAX PERIODS IN PROGRESS.</ExplanationTxt>
