        <Desc>Visiting (Whitman) Research: The MBL hosts hundreds of researchers, postdocs, and graduate students from around the world to participate in scientific discovery courses, research, lectures, and field studies. As a convener of biology, the MBL is well known for fostering a highly collaborative environment, with scientists and students engaged in intensive research in a collegial and informal atmosphere. Whitman Center Scientists are provided with infrastructure and an informal, interactive scientific community that allows them to launch into research almost immediately upon their arrival. Advice and equipment are available from other researchers or from colleagues in the education program. Free from academic duties at their home institutions, some veteran Whitman Center Scientists report they do more hands-on research in three months at the MBL than they do during the rest of the year at their home institutions.</Desc>

        <ExplanationTxt>For sub awards to institutions outside the United States, a budget, including the budget for the sub award, is prepared by the Office of Sponsored Programs (OSP) and forwarded to the prime funding agency for approval. When approval is received, an agreement between the MBL and the sub awardee is prepared. The agreement is required to include a budget, justification and description of work to be completed. Additional information such as an annual audit report may be requested as applicable. This agreement must be approved and signed by a signatory official of the sub awardee. Additional reporting is required of all foreign sub awards including itemized invoices with detailed justification of charges to verify their appropriateness and reasonableness and prepared on a basis comparable to Generally Accepted Accounting Principles (GAAP) of the United States of America. Invoices are reviewed by OSP and then forwarded to the MBL Principal Investigator (PI) for review, approval, and certification that they have been monitoring the progress of the project each time an invoice is approved. Approved invoices are forwarded to MBL Financial Services for processing. MBL may also require progress reports the same as stipulated by the prime agreement and the MBL PI.</ExplanationTxt>

        <ExplanationTxt>All trustees, officers, senior faculty, senior administrators, and other employees of the Laboratory are subject to conflict of interest policies that among other things, define material financial disclosure of information and specify procedures to be followed in managing these conflicts. The Laboratory's conflict of interest (COI) policies for trustees and officers requires disclosure whenever a trustee or a related party engages in an activity that could be considered a conflict of interest. Trustees are reminded that questions regarding the COI policy may be raised informally and confidentially at any time with the Chair of the Board of Trustees, the Chair of the Nominating and Governance Committee, or the University of Chicago's General Counsel. All trustees must annually disclose actual and potential conflicts of interest by completing a confidential COI Disclosure Statement and Acknowledgement, and these disclosures must be updated as new information becomes available that could affect the trustee's stated interests. The MBL's Director of Finance, in consultation with the Nominating and Governance Committee and senior MBL and University of Chicago administration, will compile the disclosures into a confidential database. The Chair of the Board of Trustees will also review all disclosed potential conflicts of interest before making Board committee assignments. Regardless of these efforts, Trustees must be alert to any and all potential conflicts. To the extent a potential conflict has not been addressed, it should be brought to the immediate attention of the Chair of the Board, the Chair of the Nominating and Governance Committee, or the University of Chicago's General Counsel. The Trustee should also abstain from participating in or voting on the matter. Actions in this regard will be reflected in any official meeting minutes. The Laboratory requires that employees (MBL staff members) complete a COI statement annually. The statement is reviewed by the Director of Human Resources and the Director of the Division of Research. If it is believed there may be a conflict of interest on any of the statements, it is brought to the attention of the MBL Compliance Committee for resolution. Any MBL staff member who is or will be involved in an MBL business transaction in which a potential for conflict of interest may exist is required to report such potential conflict to the Chief Operating Officer. The MBL shall take action to ensure that the transaction, if it is to proceed, is on fair and reasonable terms and in the best interest of the Laboratory. Someone other than the individual with the conflict must initiate the resolutions for action and make the necessary decisions and control the transaction(s). The individual with the conflict must recuse themselves from the decision-making process.</ExplanationTxt>
