        <ExplanationTxt>SCHEDULE A, PART IV, SECTION A, LINE 1 WAS ANSWERED "NO" BECAUSE THE ORGANIZATION IS ORGANIZED AND OPERATED AS A TYPE I SUPPORTING ORGANIZATION UNDER IRC SECTION 509(A)(3), SUPPORTING THE KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY (KAIST). IN ACCORDANCE WITH THE FOUNDATION'S BYLAWS (ARTICLE THIRD, SECTION 3.1), ALL MEMBERS OF THE FOUNDATION'S BOARD OF DIRECTORS ARE APPOINTED BY THE PRESIDENT OF KAIST, THEREBY SATISFYING THE "OPERATED, SUPERVISED, OR CONTROLLED BY" REQUIREMENT FOR TYPE I ORGANIZATIONS UNDER TREASURY REGULATION 1.509(A)-4(G)(1)(I). ALTHOUGH AT LEAST HALF OF THE BOARD MUST BE U.S. CITIZENS UNAFFILIATED WITH KAIST TO MEET U.S. GOVERNANCE REQUIREMENTS, THIS DOES NOT LIMIT KAIST'S APPOINTMENT AUTHORITY. THE FOUNDATION PROVIDES FINANCIAL AND PROGRAMMATIC SUPPORT EXCLUSIVELY TO KAIST. ALL SUPPORT IS ALIGNED WITH KAIST'S EDUCATIONAL AND SCIENTIFIC MISSION AND IS MADE AT THE SOLE DISCRETION OF THE FOUNDATION'S BOARD OF DIRECTORS.</ExplanationTxt>

        <ExplanationTxt>SCHEDULE A, PART IV, SECTION B, LINE 1 WAS ANSWERED "NO" BECAUSE THE ORGANIZATION IS NOT OPERATED IN CONNECTION WITH THE SUPPORTED ORGANIZATION IN THE MANNER REQUIRED FOR A TYPE II SUPPORTING ORGANIZATION. THE SUPPORTED ORGANIZATION DOES NOT HAVE COMMON CONTROL OR SUPERVISION OVER THE SUPPORTING ORGANIZATION, AND THERE IS NO OVERLAPPING GOVERNANCE STRUCTURE. THE ORGANIZATION QUALIFIES AS A TYPE I SUPPORTING ORGANIZATION.</ExplanationTxt>

        <ExplanationTxt>SCHEDULE A, PART IV, SECTION A, LINE 2 WAS ANSWERED "YES" BECAUSE KAIST IS A NATIONAL UNIVERSITY ESTABLISHED AND FUNDED BY THE GOVERNMENT OF THE REPUBLIC OF KOREA. IT IS A FOREIGN PUBLIC INSTITUTION OF HIGHER EDUCATION ORGANIZED AND OPERATED EXCLUSIVELY FOR SCIENTIFIC, EDUCATIONAL, AND CHARITABLE PURPOSES. WHILE KAIST DOES NOT POSSESS AN IRS DETERMINATION LETTER UNDER SECTION 501(C)(3), IT IS TREATED AS A FOREIGN EQUIVALENT OF A U.S. PUBLIC CHARITY DESCRIBED IN SECTION 509(A)(1).</ExplanationTxt>

        <FormAndLineReferenceDesc>SCHEDULE A, PART IV, SECTION A, LINE 4B</FormAndLineReferenceDesc>
        <ExplanationTxt>SCHEDULE A, PART IV, SECTION A, LINE 4B WAS ANSWERED "YES" BECAUSE THE FOUNDATION'S PRIMARY SUPPORT IS DIRECTED EXCLUSIVELY TO KAIST AS ITS SOLE SUPPORTED ORGANIZATION. HOWEVER, IN ALIGNMENT WITH ITS SUPPORT OF KAIST'S MISSION, THE FOUNDATION HAS FUNDED KAIST-LED PROGRAMS THAT ARE IMPLEMENTED IN THE UNITED STATES. THESE INCLUDE SUPPORT FOR A VOLUNTEER OUTREACH PROGRAM AT FOOTHILL COLLEGE ("LET'S PLAY AI+TECH") AND SCHOLARSHIP AWARDS GRANTED BY KAIST TO ITS U.S.-BASED ALUMNI. THESE ACTIVITIES ARE INITIATED AND OVERSEEN BY KAIST, AND THE FOUNDATION MAINTAINS FULL DISCRETION AND CONTROL OVER THE GRANT PROCESS AND USE OF FUNDS. THE SUPPORTED ORGANIZATION DOES NOT HAVE ANY RIGHT TO COMPEL PAYMENTS, AND ALL GRANT DECISIONS ARE MADE BY THE FOUNDATION'S BOARD OF DIRECTORS PURSUANT TO ITS INDEPENDENT GOVERNANCE STRUCTURE.</ExplanationTxt>

      <Form990ScheduleAPartVIGrp>
        <FormAndLineReferenceDesc>SCHEDULE A, PART IV, SECTION A, LINE 4C</FormAndLineReferenceDesc>
        <ExplanationTxt>SCHEDULE A, PART IV, SECTION A, LINE 4C WAS ANSWERED "YES" BECAUSE THE SUPPORTED ORGANIZATION DOES NOT HAVE AN IRS DETERMINATION LETTER, BUT THE FOUNDATION OPERATES UNDER GOVERNING DOCUMENTS THAT RESTRICT ALL SUPPORT EXCLUSIVELY TO PURPOSES THAT COMPLY WITH SECTION 170(C)(2)(B). THE FOUNDATION ENSURES THAT GRANTS ARE USED EXCLUSIVELY FOR CHARITABLE, EDUCATIONAL, OR SCIENTIFIC PURPOSES BY REQUIRING WRITTEN GRANT AGREEMENTS AND FOLLOW-UP REPORTING ON THE USE OF FUNDS. THE ORGANIZATION HAS NO DISCRETIONARY GRANTMAKING OUTSIDE OF THESE PURPOSES. THE FOUNDATION DOES NOT SUPPORT ANY DISQUALIFIED PERSONS, NOR DOES IT ENGAGE IN TRANSACTIONS WITH INTERESTED PERSONS, MAINTAIN OWNERSHIP INTERESTS, OR PROVIDE GRANTS OUTSIDE THE SCOPE OF ITS EXEMPT PURPOSE.</ExplanationTxt>

        <ExplanationTxt>FIN 48 FOOTNOTE: ON JANUARY 1, 2009, THE FOUNDATION ADOPTED THE RECOGNITION REQUIREMENTS FOR UNCERTAIN INCOME TAX PROVISIONS AS REQUIRED BY GENERALLY ACCEPTED ACCOUNTING PRINCIPLES, WITH NO CUMULATIVE EFFECT ADJUSTMENT REQUIRED. INCOME TAX BENEFITS ARE RECOGNIZED FOR INCOME TAX POSITIONS TAKEN OR EXPECTED TO BE TAKEN IN A TAX RETURN, ONLY WHEN IT IS DETERMINED THAT THE INCOME TAX POSITION WILL MORE-LIKELY-THAN-NOT BE SUSTAINED UPON EXAMINATION BY TAXING AUTHORITIES. THE FOUNDATION HAS ANALYZED THE TAX POSITIONS TAKEN IN ITS FILINGS WITH THE IRS AND STATE JURISDICTIONS WHERE IT OPERATES. THE FOUNDATION BELIEVES THAT ITS INCOME TAX FILING POSITIONS WILL BE SUSTAINED UPON EXAMINATION AND DOES NOT ANTICIPATE ANY ADJUSTMENTS THAT WOULD RESULT IN A MATERIAL ADVERSE AFFECT ON THE FOUNDATION'S FINANCIAL CONDITION, RESULTS OF OPERATIONS OR CASH FLOWS. ACCORDINGLY, THE FOUNDATION HAS NOT RECORDED ANY RESERVES, OR RELATED ACCRUALS FOR INTEREST AND PENALTIES FOR UNCERTAIN INCOME TAX POSITIONS AT DECEMBER 31, 2024.</ExplanationTxt>

      <ExplanationTxt>THIS RETURN IS BEING FILED AFTER THE DUE DATE BECAUSE THE TAXPAYER RELIED IN GOOD FAITH ON ITS TAX PREPARER TO FILE A FORM 990 EXTENSION. ALTHOUGH THE EXTENSION WAS PREPARED AND SAVED, IT WAS NOT TRANSMITTED DUE TO A MISSED FINAL REVIEW STEP IN THE PREPARER'S INTERNAL PROCESS. THIS OVERSIGHT WAS NOT IDENTIFIED UNTIL AFTER THE DEADLINE. THE TAXPAYER HAS TIMELY FILED FORM 990 EVERY YEAR SINCE 2017. THIS IS THE FIRST INSTANCE OF A LATE FILING. WE RESPECTFULLY REQUEST PENALTY ABATEMENT UNDER THE IRS FIRST-TIME ABATEMENT POLICY AND REASONABLE CAUSE, AS THE TAXPAYER ACTED WITH ORDINARY BUSINESS CARE BY ENGAGING A QUALIFIED PREPARER AND RELYING ON THEIR PROCESS IN GOOD FAITH. THE TAXPAYER IS TAKING STEPS TO IMPROVE PROCEDURES AND PREVENT RECURRENCE. THANK YOU FOR YOUR UNDERSTANDING.</ExplanationTxt>
