“The math learning center does not have a committee with authority to act on behalf of the board.”
“Both the cfo and the ceo review the form 990 prior to filing.”
“Board members affirm compliance with the conflict of interest policy on an annual basis. Conflicts are addressed in the organization's bylaws and in the employee handbook. The bylaws direct that any transaction between the corporation and one or more of its directors, or another party in which one more of its directors are interested, shall be valid if the fact of such relationship or interest is disclosed or known to the board of directors and it authorizes, approves, or ratifies the contract or transaction. The conflicted director shall be recused from the voting on such matter. Potential conflicts are also reviewed by the organization's legal counsel.”
“The organization employs third-party surveys to develop a market-based salary structure and benchmark all existing jobs. The ceo's compensation is reviewed and voted on by a committee of the board. The chief people officer makes a recommendation to the committee using a 3rd party compensation survey. The ceo's compensation was last reviewed in 2024.”
“The annual tax return is publicly accessible, the governing documents, conflict of interest policy, and financial statements are not available to the general public.”
“The organization adheres to generally accepted accounting principles pertaining to uncertain tax positions. Those principles call for uncertain tax positions to be recognized in the financial statements only of those positions are more likely than not to be sustained upon regulatory examination. Management is not aware of any uncertain tax positions affecting the organization's tax status or consolidated financial statements. Income tax returns for 2021,2022, and 2023 are open to examination by the irs.”
