Schedule D, Part IV, Line 2b Explanation of escrow agreement	THE BROAD INSTITUTE IS AN AGENT FOR FUNDS OF THE STARR CANCER CONSORTIUM (SCC) WHICH ARE INCLUDED ON FORM 990, PART X, LINE 2. AN OFFSETTING LIABILITY IS REPORTED FOR THE SAME AMOUNT ON FORM 990, PART X, LINE 21. THE SCC IS A COLLABORATIVE RESEARCH FRAMEWORK AMONG FIVE INSTITUTIONS INCLUDING THE BROAD INSTITUTE.
Schedule D, Part V, Line 4 Intended uses of endowment funds	The Institute's endowment consists of contributions with donor restrictions to be in vested in perpetuity to support the Institute's primary mission to propel progress in biomedicine through research aimed at the understanding and treatment of disease, and the dissemination of scientific knowledge for the public good. Net assets associated with the endowment funds are classified and reported based on the existence or absence of donor-imposed restrictions.
Schedule D, Part X, Line 2 FIN 48 (ASC 740) footnote	The Internal Revenue Service has determined that the Institute is an organization described under Internal Revenue Code (the "Code") Section 501(C (3) and, therefore, is exempt from federal income taxes on related income pursuant to Section 501(a) of the Code. Accordingly, no provision for income taxes has been recorded. The Institute recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount of benefit that is greater than fifty percent likely to be realized upon settlement. Changes in measurement are reflected in the period in which the change in judgment occurs. The Institute did not recognize the effect of any uncertain income tax positions for the years ended June 30, 2024 and 2023, respectively.
