“The return was prepared by an outside independent accounting firm and then reviewed and approved by the management team. A copy of the return was distributed to the entire board prior to filing with the irs.”
“When a potential or actual conflict of interest arises, the interested individual must fully disclose the nature and details of the financial or other interest to the board or relevant committee. Once disclosure is made, the interested person must exit the meeting so that the remaining members can evaluate whether a conflict exists. If a conflict of interest exists, the interested person may present information and respond to questions but must leave the meeting before deliberation and voting occur. The chairperson may designate a disinterested person or group to investigate alternatives to the proposed transaction, ensuring all relevant facts are known and market data (e.g., comparability studies) is gathered when appropriate. After thorough investigation and due diligence, the board or committee must assess whether a more favorable, conflict-free alternative is available. If not, they must determine whether the transaction serves the organization's best interests, is beneficial, and is fair and reasonable. A majority vote of disinterested directors is required to approve the transaction. If an interested person fails to disclose a conflict of interest, the board must investigate, allow a response, and, if necessary, take appropriate disciplinary or corrective action. Board and committee minutes must document conflict disclosures, related actions and decisions, participants in discussions, alternatives considered, and the outcomes of any votes taken.”
“The organization makes its governing documents and financial statements available to the public upon request.”
“The financial statements were reviewed by an independent accountant after the original return was filed. Consequently, the organization amended the return to align it with the figures presented in the reviewed financial statements. Parts i, iii, viii, ix, x, and schedule a have been updated to reflect these revised figures.”
“Consultant fees: program service expenses 435,143. Management and general expenses 11,671. Fundraising expenses 0. Total expenses 446,814.”

CONSEQUENTLY, THE ORGANIZATION AMENDED THE RETURN TO ALIGN IT WITH THE FIGURES PRESENTED IN THE REVIEWED FINANCIAL STATEMENTS. PARTS I, III, VIII, IX, X, AND SCHEDULE A HAVE BEEN UPDATED TO REFLECT THESE REVISED FIGURES. |
| IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt | 1 | THE RETURN WAS PREPARED BY AN OUTSIDE INDEPENDENT ACCOUNTING FIRM AND THEN REVIEWED AND APPROVED BY THE MANAGEMENT TEAM. A COPY OF THE RETURN WAS DISTRIBUTED TO THE ENTIRE BOARD PRIOR TO FILING WITH THE IRS. |
| IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt | 2 | WHEN A POTENTIAL OR ACTUAL CONFLICT OF INTEREST ARISES, THE INTERESTED INDIVIDUAL MUST FULLY DISCLOSE THE NATURE AND DETAILS OF THE FINANCIAL OR OTHER INTEREST TO THE BOARD OR RELEVANT COMMITTEE. ONCE DISCLOSURE IS MADE, THE INTERESTED PERSON MUST EXIT THE MEETING SO THAT THE REMAINING MEMBERS CAN EVALUATE WHETHER A CONFLICT EXISTS. IF A CONFLICT OF INTEREST EXISTS, THE INTERESTED PERSON MAY PRESENT INFORMATION AND RESPOND TO QUESTIONS BUT MUST LEAVE THE MEETING BEFORE DELIBERATION AND VOTING OCCUR. THE CHAIRPERSON MAY DESIGNATE A DISINTERESTED PERSON OR GROUP TO INVESTIGATE ALTERNATIVES TO THE PROPOSED TRANSACTION, ENSURING ALL RELEVANT FACTS ARE KNOWN AND MARKET DATA (E.G., COMPARABILITY STUDIES) IS GATHERED WHEN APPROPRIATE. AFTER THOROUGH INVESTIGATION AND DUE DILIGENCE, THE BOARD OR COMMITTEE MUST ASSESS WHETHER A MORE FAVORABLE, CONFLICT-FREE ALTERNATIVE IS AVAILABLE. IF NOT, THEY MUST DETERMINE WHETHER THE TRANSACTION SERVES THE ORGANIZATION'S BEST INTERESTS, IS BENEFICIAL, AND IS FAIR AND REASONABLE. A MAJORITY VOTE OF DISINTERESTED DIRECTORS IS REQUIRED TO APPROVE THE TRANSACTION. IF AN INTERESTED PERSON FAILS TO DISCLOSE A CONFLICT OF INTEREST, THE BOARD MUST INVESTIGATE, ALLOW A RESPONSE, AND, IF NECESSARY, TAKE APPROPRIATE DISCIPLINARY OR CORRECTIVE ACTION. BOARD AND COMMITTEE MINUTES MUST DOCUMENT CONFLICT DISCLOSURES, RELATED ACTIONS AND DECISIONS, PARTICIPANTS IN DISCUSSIONS, ALTERNATIVES CONSIDERED, AND THE OUTCOMES OF ANY VOTES TAKEN. |
