“Review of form 990 the first draft of the 990 was developed by an external accounting firm under the direction of the controller with additional guidance from the chief financial officer (cfo). It was reviewed for accuracy and completeness by the cfo and then by the chief executive officer (ceo). Then a meeting of the audit committee was held at which the cfo and external accounting firm walked through the draft in detail for the audit committee's approval. The foundation provided the members of the governing body 7 days notice to review the complete copy of the form 990 prior to filing with the internal revenue service.”
“The organization's board members, officers, executives, and key employees (covered persons) complete annually a conflict-of-interest statement the purpose of which is to identify any personal, family and/or business relationships and/or transactions that may pose a potential conflict. The filed conflict of interest forms are submitted to and reviewed by the general counsel and only reviewed by the board if needed. Additionally, covered persons complete annually a pledge of personal commitment that affirms that the individual is in compliance with the conflict-of-interest policy and that the individual will promptly notify the chief executive officer and the board chair when a conflict or potential conflict arises. Furthermore, in the case of a conflict, the individual agrees to refrain from using his or her personal influence to encourage the foundation to enter the transaction and must physically excuse himself or herself from any further discussions other than to answer questions about the transaction. In the case of potential conflict, the remaining board members review the potential transaction to determine whether said transaction is fair and reasonable to the foundation and legal counsel is consulted as necessary to ensure that such a transaction would not constitute an excess benefit transaction.”
“The wikimedia foundation talent & culture committee, a board committee, is responsible for recommending the compensation of the ceo and assisting the board in performing annual review of the compensation of the ceo and officers, and key employees. For 2023 compensation, the board of trustees reviewed the proposed compensation of the ceo and made a decision informed by compensation data from comparable organizations. The board of trustees deliberations and decision were contemporaneously documented, including who attended and voted and a description of the comparable documentation used and how it was obtained.”
