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	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. AT SEPTEMBER 30, 2023 AND 2022, THE INSTITUTE MAINTAINED A FULL VALUATION ALLOWANCE ON ITS DEFERRED TAX ASSETS. THE VALUATION ALLOWANCE REDUCED NET DEFERRED TAX ASSETS, WHICH ARE PRIMARILY DUE TO TAX LOSSES FROM CERTAIN INVESTMENT ACTIVITIES, TO A VALUE OF $0. BASED ON ITS ANALYSIS OF THE UNCERTAINTIES SURROUNDING BOTH THE TIMING AND AMOUNTS OF POTENTIAL FUTURE NET TAXABLE INCOME, THE INSTITUTE HAS ASSUMED THAT IT IS MORE LIKELY THAN NOT THAT THE INSTITUTE WILL NOT REALIZE THE DEFERRED TAX ASSETS. THE INSTITUTE HAS NOT PROVIDED FOR ANY UNCERTAIN TAX POSITIONS AT SEPTEMBER 30, 2023 AND 2022. 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 $10,947 AND $7,288 AT SEPTEMBER 30, 2023 AND 2022, RESPECTIVELY.

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 2022, THREE 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 $64,771, WHICH IS AN ESTIMATE OF THE ANNUAL RENTAL VALUE OF THE PERSONAL SPACE OCCUPIED IN THAT RESIDENCE.
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. DURING CALENDAR YEAR 2022, FIVE INDIVIDUALS REPORTED IN SCHEDULE J - SCOTT RICHLAND, PASY WANG, DOUGLAS MACBEAN, ALISTAIR THISTLETHWAITE AND BRIAN CHEN - RECEIVED SUCH COMPENSATION. SCOTT RICHLAND PARTICIPATES IN THE CHIEF INVESTMENT OFFICER PERFORMANCE COMPENSATION PLAN, WHILE PASY WANG, DOUGLAS MACBEAN, ALISTAIR THISTLETHWAITE AND BRIAN CHEN PARTICIPATE IN THE INVESTMENT OFFICE STAFF PERFORMANCE COMPENSATION PLAN. UNDER BOTH PLANS, 50% OF THE AWARDS ARE PAID AFTER THE CONCLUSION OF THE PLAN YEAR (WHICH COINCIDES WITH THE CALENDAR 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. UNDER CERTAIN CIRCUMSTANCES, 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"). NO SUCH SPECIAL VESTING OCCURRED IN 2022. FOR PASY WANG, DOUGLAS MACBEAN, ALISTAIR THISTLETHWAITE AND BRIAN CHEN, THE INDIVIDUAL AMOUNTS IN COLUMN B(II) (BONUS AND INCENTIVE COMPENSATION) COMPRISE PLAN CASH AMOUNTS PAID PURSUANT TO THE PLAN DURING CALENDAR YEAR 2022 AND REPRESENT THE AGGREGATE OF 50% OF EACH EMPLOYEE'S RESPECTIVE AWARD FROM CALENDAR YEAR 2021, AS WELL AS INSTALLMENTS OF AMOUNTS DEFERRED FROM PLAN YEARS 2018-2020. SCOTT RICHLAND, HOWEVER, HAD VESTED IN ALL OUTSTANDING DEFERRED AWARDS EFFECTIVE JANUARY 1, 2021 THROUGH SPECIAL VESTING. THEREFORE, THE INDIVIDUAL AMOUNT REPORTED FOR SCOTT RICHLAND IN COLUMN B(II) (BONUS AND INCENTIVE COMPENSATION) ONLY INCLUDES 50% OF HIS AWARD EARNED IN CALENDAR YEAR 2021 AND PAID IN CALENDAR YEAR 2022. FOR SCOTT RICHLAND, DOUGLAS MACBEAN, ALISTAIR THISTLETHWAITE AND BRIAN CHEN, AMOUNTS IN COLUMN C (RETIREMENT AND OTHER DEFERRED COMPENSATION) INCLUDE DEFERRED INCENTIVE COMPENSATION AWARDS EARNED IN CALENDAR YEAR 2022 THAT ARE SUBJECT TO FORFEITURE UNDER CERTAIN CIRCUMSTANCES. SUCH AMOUNTS WOULD BE PAID IN INSTALLMENTS, ALONG WITH ANY PRIOR YEARS' DEFERRALS, IN CALENDAR YEAR 2023 AND BEYOND. FOR PASY WANG, COLUMN C (RETIREMENT AND OTHER DEFERRED COMPENSATION) DOES NOT INCLUDE ANY DEFERRED INCENTIVE COMPENSATION AWARDS BECAUSE, DUE TO HER RESIGNATION FROM THE INSTITUTE DURING CALENDAR YEAR 2022, SHE FORFEITED HER ELIGIBILITY TO RECEIVE HER 2022 AWARD, AS WELL AS ALL PRIOR YEARS' REMAINING DEFERRALS.
