Desc	Visiting (Whitman) Research: The Marine Biological Laboratory 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 Marine Biological Laboratory is well known for fostering a highly collaborative environment, with scientists and students engaged in intensive research in a collegial and informal atmosphere. Largely a summer program, 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.

Schedule D, Part III, Line 4	Rare books, journals and prints are located and used in the MBL Library for research and preservation.
Schedule D, Part V, Line 4	The endowment funds were established for a variety of purposes, including research, scholarships, library, plant, and unrestricted.
Schedule D, Part X, Line 2	The Laboratory is a tax-exempt organization described in Section 501(c)(3) of the Internal Revenue Code, as amended (the Code), and is generally exempt from income taxes pursuant to Section 501(a) of the Code. The Laboratory is required to assess uncertain tax positions and has determined that there were no such positions that are material to the financial statements. Management believes that the Laboratory's income tax returns for years ended prior to 2015 are no longer subject to examination by tax authorities in its major tax jurisdiction. On December 22, 2017, the President signed into law H.R. 1, originally known as the Tax Cuts and Jobs Act. The new law includes several provisions that result in substantial changes to the tax treatment of tax-exempt organizations and their donors. The Laboratory has reviewed these provisions and the potential impact and concluded the enactment of H.R. 1 will not have a material effect on the operations of the organization.

Explanation	For subawards to institutions outside the United States, a budget, including the budget for the subaward, 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 subawardee 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 subawardee. Additional reporting is required of all foreign subawards 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 Principle 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

Schedule I, Part I, Line 2

The Federal Grants Accountant, Senior Accountant, and Director of Finance oversee all grant, contract or cooperative agreement awards compliance. This includes establishing a new job center for each award, reconciling allowable expenses to the sponsor's requirements, accounting of all costs on active awards, ensuring grant contract or cooperative agreement expenses do not exceed the award revenues, completing all billing to government and private agencies, and completing a financial close-out of all finished awards assuring proper reporting to federal and non-federal agencies.

Schedule I, Part III

Research award oversight is provided by the Division of Research staff. Research award applications are reviewed by a committee of internal and external scientists, who meet with the Director of the Division of Research to make their recommendations for the final determination of recipients and award amounts. The Senior Administrator in the Division of Research tracks the awardee's research progress and expenditures through their stay at the MBL, reviewing the required reports that are due one month after completion of the research award term, and ensuring awardees remain within budget. Scholarships are awarded by the Division of Research from grants and contributions received by the MBL, some of which are restricted for specific use. The Director of the Division of Education determines student eligibility and the amount of the scholarship. Awards are first applied to cover tuition costs, and then cover room, board, and travel if the amount awarded is sufficient.

Form 990, Part VI, Section A, Line 6	On July 1, 2013 the Laboratory entered into an affiliation agreement with the University of Chicago (the University) located in Chicago, Illinois. Under this affiliation the University became the sole member of the Laboratory. The University of Chicago as sole member has the right to exercise all powers to approve or disapprove of certain fundamental decisions concerning the Corporation.
Form 990, Part VI, Section A, Line 7a	The University as sole member has the power to appoint and remove members of the Board Directors.
Form 990, Part VI, Section A, Line 7b	The University of Chicago as sole member has the power to take certain actions with respect to the MBL after prior consultation with the MBL's Board of Directors, and the power to approve or disapprove certain actions taken by the MBL.
Form 990, Part VI, Section B, Line 11b	Prior to filing the Form 990, members of the Executive Committee and Audit Committee of the Laboratory's Board of Trustees were given an opportunity to review portions of the Form 990 relevant to the areas of oversight of those Committees, allowing them to review the form, provide comments, and ask any questions. Subsequent to the Committees' review, the form is made available to the full Board of Trustees for review prior to filing.
Form 990, Part VI, Section B, Line 12c	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 University of Chicago's General Counsel, in consultation with the Nominating and Governance Committee and senior laboratory administration, will compile the disclosures into a confidential database and prepare for each trustee a written acknowledgement of the disclosure that identifies any pending Laboratory transactions that may be affected by the disclosure. 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.
Form 990, Part VI, Section C, Line 19	The Conflict of Interest policy is available on MBL's website. Audited financial statements and Form 990 are available upon request to organization. In addition, audited financial statements, Form 990, and governing documents are available on public websites and the Commonwealth of Massachusetts' website.
Form 990, Part XI, Line 9	Adjust for non-operating activities: deduct change in value of interest swap rate of $1,290,630, add change in annuities of $58,045, deduct change in post-retirement health care liability of $249,882, deduct non-operating contributions of $365,228, deduct other non-operating activity of $74,289, total of $1,921,984.
