GRANTS FUNDS OUTSIDE THE U.S.: Procedures for monitoring use of grant funds outside the U.S. Potential grantees participate in a grants application process by providing a proposal. The proposal contains a description of the mission related work they are proposing, a budget, a timeline and how this will impact the mission goals. Once an applicant is awarded a grant, they receive an email stipulating that by accepting funds,they agree to the reporting requirements which include maintaining receipts/documentation of expenses, agreeing to return unused funds and/or submit a request for reallocation of funds, and submission of a final report which includes an estimate of the impact of the funded activities on mission goals and a summary of best practices and lessons learned.
GRANT FUNDS TO INDIVIDUALS PROCEDURES FOR MONITORING USE OF GRANT FUNDS TO INDIVIDUALS: Grants to individuals follow the same process as other grants unless they are travel scholarships. Individuals apply for travel scholarships (primarily to attend the annual conference, Wikimania) and applications are reviewed and either accepted or denied. In most cases, travel is then arranged for the individual and paid for directly by The Wikimedia Foundation. In very limited cases, individuals book travel themselves and provide receipts to the Foundation which then reimburses them based on the receipts.

Form 990 part VI, line 7A   The Board consists of ten Trustees. Three seates are elected directly by the Wikimedia community and two seats are selected by the Wikimedia chapters. Form 990 part VI, line 11a Review of Form 990: The first draft of the 990 was developed by an external accounting firm under the direction of the Chief of Finance and Administration (CF). It was reviewed for accuracy and completeness by the CFA and then by the Executive Director. Then a meeting of the audit committee was held at which the CFA walked through the draft in detail for the audit committee's approval. A complete copy of the Form 990 was provided to the voting members of the governing body prior to filing with the Internal Revenue Service. Form 990 Part VI, Line 12 Conflict of interest: The organization's board members, officers, 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. These forms are submitted to the general counsel and are reviewed by the Board. Additionally, the covered persons also 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 Executive Director 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.
Form 990 Part VI Line 15a and 15b   Form 990 Part VI Line 15a- The Wikimedia Foundation Board of Trustees is responsible for determining the compensation of the Executive Director, and has delegated that responsibility to the ED Evaluation Committee and board treasurer which is comprised of independent Board members. For 2010 compensation, in setting the ED's compensation,the Evaluation Committee has secured and reviewed comparability data about non-profit CEO compensation for organizations of similar size and scope to the Wikimedia Foundation, including salary, bonuses and non-monetary benefits and perquisites. The information came from a variety of sources including Guidestar, Boardsource, the Center for Non-Profit Management, and the Non-Profit Times. The committee also consulted with independent experts in the field. The Evaluation Committee also annually sets performance goals with the Executive Director, and works with her to evaluate performance against those goals. Both compensation and performance assessment information is shared with the full Board for its review and approval. At various points in the process, discussions and deliberations are reviewed via email. Once deliberations are complete, the final determination is summarized by the Board Treasurer in writing. Form 990 Part VI Line 15b- The Wikimedia Foundation Executive Director is responsible for determining the compensation of all Wikimedia Foundation officers and key employees (with the exception of herself). In setting compensation for Wikimedia Foundation officers and key employees, the Executive Director has secured and reviewed comparability data about compensation at organizations of similar size and scope to the Wikimedia Foundation, including salary, bonuses and non-monetary benefits and perquisites. The information came from a variety of sources including Guidestar, Boardsource, the Center for Non-Profit Management, the Non-Profit Times, the San Francisco Business Times, CompassPoint Nonprofit Services and the Meyer Foundation. Additionally, the Executive Director and her staff have consulted with independent experts in the field, including those with specific subject-matter expertise in areas of non-monetary compensation such as health and dental coverage and retirement saving plans. The Executive Director also annually sets performance goals with officers and key employees, and works with them to evaluate performance based on those goals. Both compensation and performance assessment information is shared at a high level with the Board of Trustees, but the Board does not review this information in detail, nor does it approve specifics.
