“Form 990 is reviewed by the audit committee and legal counsel and then distributed to the board of directors prior to filing.”
“The conflict of interest policy covers directors, officers, key employees, committee members, spouses or domestic partners of any of the listed people, and former officers, directors or key employees who served in such capacity within the five previous years. In connection with any actual or possible conflict of interest, a covered person must immediately disclose to the board, committee or board designee the existence and nature of his or her financial interest or any disclosable relationships. All newly appointed or elected board members or officers shall disclose all known conflicts of interest and disclosable relationships upon assumption of their duties, and should a conflict of interest or disclosable relationship develop, must immediately disclose to the board, committee or board designee such actual or possible conflict of interest or disclosable relationship. After a potential conflict has been disclosed, the board or committee shall determine if a conflict of interest exists. If the board or committee determines that a covered person has a financial interest, then it will be investigated and determined by a majority vote of the disinterested board members whether the transaction or arrangement is in the organization's best interests. Covered persons are required to review and certify compliance with the policy on an annual basis.”
“The organization's governing documents, conflict of interest policy and financial statements are made available to the public upon request when required by federal or state law.”
“Fine 48 (asc 740) uncertain tax positions financial statements footnote: the organization recognizes the tax benefit from uncertain tax positions only if it more likely than not that the tax positions will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The organization recognizes interest and penalties, if any, related to income tax matters in federal tax expense. The organization has no unrecognized tax benefits at december 31, 2021 or 2020.”
