        <ExplanationTxt>THE FOUNDATION ACCOUNTS FOR THE EFFECT OF ANY UNCERTAIN TAX POSITIONS BASED ON A "MORE LIKELY THAN NOT" THRESHOLD TO THE RECOGNITION OF THE TAX POSITIONS BEING SUSTAINED BASED ON THE TECHNICAL MERITS OF THE POSITION UNDER SCRUTINY BY THE APPLICABLE TAXING AUTHORITY. IF A TAX POSITION OR POSITIONS ARE DEEMED TO RESULT IN UNCERTAINTIES OF THOSE POSITIONS, THE UNRECOGNIZED TAX BENEFIT IS ESTIMATED BASED ON A "CUMULATIVE PROBABILITY ASSESSMENT" THAT AGGREGATES THE ESTIMATED TAX LIABILITY FOR ALL UNCERTAIN TAX POSITIONS. THE FOUNDATION HAS IDENTIFIED ITS TAX STATUS AS A TAX EXEMPT ENTITY AS A TAX POSITION; HOWEVER, THE SCHOOL HAS DETERMINED THAT SUCH TAX POSITION DOES NOT RESULT IN AN UNCERTAINTY REQUIRING RECOGNITION.</ExplanationTxt>
