“The investment and audit committees periodically meet in executive session. Although separate meeting minutes are not kept, they report back to the full board where minutes are kept.”
“Several individuals associated with the organization diligently gather and prepare all data and narrative explanations to accurately complete the irs form 990. Several drafts of the form 990 are reviewed and edited by management, officers, internal counsel, outside counsel, and accountants. All directors receive a final copy of the 990 prior to filing.”
“Under the conflict of interest policy, individuals are to report any potential conflicts with respect to particular decisions as they arise, and if the board determines that a conflict exists, the conflicted individual does not participate in voting on that decision (and in some cases the foundation may not pursue the transaction at all). This policy has been consistently enforced. In addition, the foundation periodically asks board members and key employees to respond to a questionnaire detailing potential conflicts of interest. It did not send the questionaire out this year but intends to do so in 2025. While the foundation has not engaged in additional monitoring or enforcement beyond this, it believes its existing mechanisms have been adequate to protect against conflicts of interest affecting the board's decision making.”
“The board of directors determined the president's compensation after taking into account assessments of his individual performance and that of the organization as a whole, along with market data about executive compensation at similar organizations drawn from both general surveys and the forms 990 for a set of peer institutions. The president and interested parties were absent from the final board discussion, and the determination was ultimately approved during a part of a meeting of the board of directors not including anyone with a conflict of interest regarding the compensation package. The process and the data on which the decision was made is documented in the minutes of the organization.”
“The forms 990, 990-t, and the form 1023 in their original form are available upon request. We also make these forms available online, along with our financial statements and governing documents, except that to protect individual privacy some personal address information is redacted from the version made available online.”
“The ty23 form 990 erroneously reported a portion of program related investment as temporary cash investment and reported a portion of net assets without donor restrictions in the count of net assets with donor restrictions. These amounts are now accurately reflected in the beginning balances for ty24 and in the respective schedules of this return.”
“The foundation qualifies as a public benefit charitable organization exempt from income taxes on related income under section 501(c)(3) of the internal revenue code and applicable sections of the california revenue and taxation code. The foundation provides for tax, if any, on unrelated business income. In accordance with the accounting standard on accounting for uncertainty in income taxes, no portion of an uncertain tax position will be recognized if the position has less than a 50% likelihood of being sustained upon audit by the relevant taxing authority. Also, interest expense, if any, is recognized on the full amount of deferred benefits for uncertain tax positions. The foundation's consolidated financial statements reported some unrecognized tax benefits, but those benefits all resulted from tax positions taken by other entities in the group, not the foundation.”
