SCHEDULE D, PART III, LINE 1A	THE INSTITUTE DOES NOT CAPITALIZE ITS COLLECTION ITEMS. DUE TO THE IMMATERIALITY OF THE EFFECT OF COLLECTIONS PRACTICES ON ITS FINANCIAL STATEMENTS, THE INSTITUTE DOES NOT DISCLOSE ITS COLLECTIONS POLICIES.
SCHEDULE D, PART III, LINE 4	THE INSTITUTE MAINTAINS A COLLECTION OF INSTITUTIONAL RECORDS, DOCUMENTS, ARTIFACTS, AND SPECIMENS FOR HISTORICAL PRESERVATION, INSTRUCTION, AND SCHOLARLY RESEARCH.
SCHEDULE D, PART IV, LINE 2B	THE INSTITUTE IS THE TRUSTEE OF DONOR ANNUITIES AND TRUST AGREEMENTS AND MANAGES CERTAIN INVESTMENT FUNDS FOR OTHERS, SUCH AS RELATED ORGANIZATIONS.
SCHEDULE D, PART V, LINE 4	THE INSTITUTE'S ENDOWMENT IS COMPRISED OF DONOR-RESTRICTED AND BOARD-DESIGNATED FUNDS HELD FOR LONG-TERM INVESTMENT. THROUGH AN ANNUAL SPENDING ALLOCATION, THE ENDOWMENT SUPPORTS THE MISSION OF EDUCATION AND RESEARCH AND GENERAL OPERATING ACTIVITIES OF THE INSTITUTE. THE INSTITUTE'S ENDOWMENT SPENDING POLICY INCLUDES A BOARD OF TRUSTEES-APPROVED ENDOWMENT SPENDING FORMULA WHICH TAKES INTO CONSIDERATION THE PRIOR YEAR'S SPENDING, INFLATION FACTORS, AND ENDOWMENT GROWTH. THE INSTITUTE INVESTS ENDOWMENT ASSETS TARGETED TO EARN AN AVERAGE ANNUAL TOTAL RETURN THAT EXCEEDS INFLATION BY AT LEAST THE AMOUNT REQUIRED TO SUPPORT THE ENDOWMENT SPENDING. ALL ENDOWMENT ASSETS ARE HELD IN THE INVESTMENT POOL UNLESS SPECIAL CONSIDERATIONS OR DONOR STIPULATIONS REQUIRE THAT THEY BE INVESTED SEPARATELY. TOTAL RETURN INCLUDES BOTH CAPITAL APPRECIATION/DEPRECIATION (REALIZED AND UNREALIZED GAINS/LOSSES) AND INVESTMENT INCOME (INCLUDING INTEREST, DIVIDENDS, AND ROYALTIES). THE INSTITUTE TARGETS A DIVERSIFIED ASSET ALLOCATION, INCLUDING INVESTMENTS IN BOTH PUBLIC MARKETS AND IN ALTERNATIVE INVESTMENTS, WITHIN RISK CONSTRAINTS DEEMED TO BE PRUDENT.
SCHEDULE D, PART VII, LINE 3A	ALTERNATIVE SECURITIES INCLUDE, BUT ARE NOT LIMITED TO, SUBSTANTIAL INVESTMENT HOLDINGS THAT ARE ILLIQUID AND/OR CONTAIN VARIOUS REDEMPTION RESTRICTIONS.
SCHEDULE D, PART X, LINE 2	EXCEPT AS NOTED BELOW, THE INSTITUTE IS GENERALLY EXEMPT FROM FEDERAL TAXES ON INCOME RELATED TO ITS CHARITABLE PURPOSE UNDER THE PROVISIONS OF IRC SECTION 501(C)(3) AND FROM CALIFORNIA AND OTHER STATE INCOME TAXES UNDER CORRESPONDING STATE LAWS. THE INSTITUTE IS SUBJECT TO BOTH FEDERAL AND STATE INCOME TAXES ON INCOME FROM CERTAIN ACTIVITIES NOT SUBSTANTIALLY RELATED TO ITS EXEMPT PURPOSE. IN PREVIOUS YEARS, THE INSTITUTE HAD MAINTAINED A FULL VALUATION ALLOWANCE ON ITS DEFERRED TAX ASSETS, WHICH ARE PRIMARILY DUE TO HISTORICAL LOSSES FROM CERTAIN INVESTMENT ACTIVITIES. THIS HAD REDUCED NET DEFERRED TAX ASSETS TO A VALUE OF $0 AS OF SEPTEMBER 30, 2023. BASED ON ITS ANALYSIS OF BOTH THE TIMING AND AMOUNTS OF POTENTIAL FUTURE NET TAXABLE INCOME, THE INSTITUTE NOW ASSUMES THAT IT IS MORE LIKELY THAN NOT THAT THE INSTITUTE WILL REALIZE THE DEFERRED TAX ASSETS AND HAS LIFTED THE VALUATION ALLOWANCE. AT SEPTEMBER 30, 2024, THE INSTITUTE'S DEFERRED TAX ASSET WAS $5,707,000 AND IS INCLUDED IN THE LINE ITEM "PREPAID EXPENSES AND OTHER ASSETS" IN THE BALANCE SHEETS. THE INSTITUTE HAS NOT PROVIDED FOR ANY UNCERTAIN TAX POSITIONS AT SEPTEMBER 30, 2024 AND 2023. THE INSTITUTE IS SUBJECT TO A FEDERAL EXCISE TAX ON NET INVESTMENT INCOME. THE INSTITUTE'S DEFERRED TAX LIABILITY RELATED TO THE EXCISE TAX WAS $16,688,000 AND $10,947,000 AT SEPTEMBER 30, 2024 AND 2023, RESPECTIVELY, AND IS INCLUDED IN THE LINE ITEM "DEFERRED REVENUE, REFUNDABLE ADVANCES, AND OTHER" IN THE BALANCE SHEETS.

SCHEDULE J, PART I, LINE 1A	FIRST CLASS TRAVEL: PURSUANT TO A WRITTEN POLICY, FIRST CLASS OR BUSINESS TRAVEL IS PERMITTED FOR CERTAIN EMPLOYEES UNDER CERTAIN CIRCUMSTANCES FOR BUSINESS PURPOSES. DURING CALENDAR YEAR 2023, THREE OFFICERS RECEIVED FIRST CLASS OR CHARTER TRAVEL BENEFITS. TRAVEL FOR BUSINESS PURPOSES IS NOT INCLUDED IN TAXABLE WAGES. TAX INDEMNIFICATION AND GROSS-UP PAYMENTS: DURING CALENDAR YEAR 2023, TWO OFFICERS AND ONE HIGHEST COMPENSATED EMPLOYEE RECEIVED TAX INDEMNIFICATION AND GROSS-UP PAYMENTS. HOUSING ALLOWANCE: HOUSING ALLOWANCES ARE PROVIDED TO CERTAIN OFFICERS, KEY EMPLOYEES, AND HIGHEST COMPENSATED EMPLOYEES AS PART OF THE INSTITUTE'S SALARY SUPPLEMENT HOUSING PROGRAM, WHICH IS GOVERNED BY A WRITTEN POLICY. DURING CALENDAR YEAR 2023, FOUR OFFICERS RECEIVED HOUSING ALLOWANCE BENEFITS. PAYMENTS UNDER THIS PROGRAM ARE INCLUDED IN TAXABLE WAGES. ADDITIONALLY, THE PRESIDENT OCCUPIES AN INSTITUTE-OWNED RESIDENCE ON ITS CAMPUS AS A CONDITION OF EMPLOYMENT FOR THE CONVENIENCE OF THE INSTITUTE. THE PRESIDENT'S NONTAXABLE BENEFITS IN SCHEDULE J, PART II, COLUMN (D) INCLUDE $79,054, WHICH IS AN ESTIMATE OF THE ANNUAL RENTAL VALUE OF THE PERSONAL SPACE OCCUPIED IN THAT RESIDENCE.
SCHEDULE J, PART I, LINE 4A	IN 2023, KAREN SISSON, FORMER VP OF ADMINISTRATION AND CFO, RECEIVED A SEVERANCE PAYMENT OF $616,667 UPON HER SEPARATION FROM THE INSTITUTE. THIS PAYMENT WAS MADE PURSUANT TO THE TERMS OF HER EMPLOYMENT AGREEMENT. THE TOTAL REPORTED FOR KAREN SISSON ABOVE IN COLUMN B(III) (OTHER REPORTABLE COMPENSATION) INCLUDES THIS PAYMENT.
SCHEDULE J, PART I, LINE 4B	TERMS AND CONDITIONS OF PERFORMANCE COMPENSATION PLANS FOR INVESTMENT PROFESSIONALS: IN 2011, THE INSTITUTE ESTABLISHED A PERFORMANCE COMPENSATION PLAN ("PLAN") TO ASSIST WITH RECRUITMENT AND RETENTION FOR ITS INVESTMENT OFFICE. UNDER THE TERMS OF THE PLAN, PARTICIPANTS ARE ELIGIBLE FOR CERTAIN AWARDS BASED UPON THE PERFORMANCE OF THE INSTITUTE'S INVESTMENT OFFICE EACH CALENDAR YEAR, AS MEASURED BY CERTAIN QUANTITATIVE AND QUALITATIVE FACTORS. IN 2017, THE PLAN WAS SPLIT INTO TWO SEPARATE PERFORMANCE COMPENSATION PLANS, ONE FOR THE CHIEF INVESTMENT OFFICER AND ONE FOR THE INVESTMENT OFFICE STAFF. UNDER THE TERMS OF THE CHIEF INVESTMENT OFFICER PERFORMANCE COMPENSATION PLAN, EFFECTIVE JANUARY 1, 2023, THE PARTICIPANT IMMEDIATELY VESTS IN ANY UNVESTED BONUS AMOUNTS AT THE END OF THE PLAN YEAR (WHICH COINCIDES WITH THE CALENDAR YEAR). THEREFORE, FOR THE INSTITUTE'S PURPOSES, NO PORTION OF THE AWARD EARNED IS CONSIDERED DEFERRED. HOWEVER, FOR PURPOSES OF REPORTING ON SCHEDULE J, THE PORTION OF THE AWARD PAID SUBSEQUENT TO MARCH 15TH OF THE FOLLOWING CALENDAR YEAR IS TREATED AS "DEFERRED." UNDER THE TERMS OF THE INVESTMENT OFFICE STAFF PERFORMANCE COMPENSATION PLAN, 50% OF THE AWARDS ARE PAID AFTER THE CONCLUSION OF THE PLAN YEAR, WHILE THE REMAINING 50% OF EACH YEAR'S AWARD IS DEFERRED, VESTS, AND IS PAID IN THREE ANNUAL INSTALLMENTS, AS ADJUSTED BY THE POSITIVE OR NEGATIVE PERFORMANCE OF THE ENDOWMENT EACH YEAR. ADDITIONALLY, UNDER CERTAIN CIRCUMSTANCES, AND SUBJECT TO A MINIMUM NUMBER OF YEARS OF PARTICIPATION IN THE PLAN, PREVIOUSLY DEFERRED, BUT UNVESTED, AMOUNTS MAY BE PAID TO THE PARTICIPANT BASED UPON THEIR AGE AND LENGTH OF SERVICE ("SPECIAL VESTING"). DURING CALENDAR YEAR 2023, THREE INDIVIDUALS REPORTED IN SCHEDULE J RECEIVED SUCH COMPENSATION. SCOTT RICHLAND (CHIEF INVESTMENT OFFICER) PARTICIPATES IN THE CHIEF INVESTMENT OFFICER PERFORMANCE COMPENSATION PLAN. DOUGLAS MACBEAN (SENIOR MANAGING DIRECTOR OF INVESTMENTS) AND KIRK KAWASAWA (SENIOR MANAGING DIRECTOR OF INVESTMENT OPERATIONS) PARTICIPATE IN THE INVESTMENT OFFICE STAFF PERFORMANCE COMPENSATION PLAN. THE INDIVIDUAL AMOUNTS IN COLUMN B(II) (BONUS AND INCENTIVE COMPENSATION) REFLECT CASH AMOUNTS PAID PURSUANT TO THE PLAN DURING CALENDAR YEAR 2023. FOR SCOTT RICHLAND AND KIRK KAWASAWA, THESE AMOUNTS INCLUDE THE TOTAL OF EACH EMPLOYEE'S RESPECTIVE AWARD EARNED IN PLAN YEAR 2022, AS WELL AS INSTALLMENTS OF AMOUNTS DEFERRED FROM PLAN YEAR 2021. KIRK KAWASAWA SPECIAL VESTED IN HIS AWARDS IN AUGUST 2023, RESULTING IN THE PAYOUT OF ALL REMAINING DEFERRED AWARD INSTALLMENTS DURING 2023. FOR DOUGLAS MACBEAN, THE AMOUNT IN COLUMN B(II) INCLUDES THE AGGREGATE OF 50% OF THE AWARD EARNED IN PLAN YEAR 2022, AS WELL AS PREVIOUSLY DEFERRED INSTALLMENTS FROM AWARDS EARNED IN PLAN YEARS 2019 THROUGH 2021. FOR ALL PLAN PARTICIPANTS, AMOUNTS IN COLUMN C (RETIREMENT AND OTHER DEFERRED COMPENSATION) REFLECT THE DEFERRED PORTION OF AWARDS EARNED IN CALENDAR YEAR 2023, WHICH IS EQUAL TO THE TOTAL CALENDAR YEAR AWARD EARNED LESS THE PORTION OF THAT AWARD PAID PRIOR TO MARCH 15, 2024. THE DEFERRED PORTION OF THESE AWARDS IS SUBJECT TO FORFEITURE UNDER CERTAIN CIRCUMSTANCES AND THE REMAINING INSTALLMENTS WILL BE PAID IN SUBSEQUENT PLAN YEARS.
SCHEDULE J, PART I, LINE 7	Certain individuals listed in Part II of Schedule J received bonuses in recognition of excellent job performance or as a negotiated payment at the beginning of an employment arrangement. For example, the Institute offers performance-based compensation to certain investment professionals based upon the Institute's investment performance and other factors (see response to Line 4B above). Bonus recipients' names and amounts paid are shown in Schedule J, Part II, Column B(II) (Bonus and Incentive Compensation).
