SchD_P05_S00_L04	Schedule D, Part V, Line 4	The endowment funds were established for a variety of purposes, including research, scholarships, library, plant and unrestricted.
SchD_P10_S00_L02	Schedule D, Part X, Line 2	The Laboratory is a tax-exempt organization as described in Section 501(c)(3) of the Internal Revenue Code (the Code) and is generally exempt from income taxes pursuant to Section 501(a) of the Code. In fiscal year 2009, the Laboratory adopted guidance which requires recognition of the benefit of a tax position only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant taxing authority. Management believes that the Laboratory's income tax returns for years ended prior to 2008 are no longer subject to examination by tax authorities in its major tax jurisdiction.

SchI_P01_S00_L02	Schedule I, Part I, Line 2	The Grants Accountant and Controller 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.
SchI_P03_S00_L00	Schedule I, Part III	Research award oversight is provided by the Office of the Chief Academic and Scientific Officer (CASO). Research award applications are reviewed by a committee of internal and external scientists, who forward their recommendations to the President/Director and CASO who make the final determination of specific awards and award amount. The CASO then forwards an acceptance letter and contract to each awardee, listing the terms and reporting requirements of the award. The CASO office then tracks the awardee's research progress and expenditures through their stay at MBL to ensure that the awardees stay closely within budget, and reviews the required report due approximately one month after the completion of the term covered by the research award. Scholarships are awarded by the Education Office from grants and contributions, many of which have limitations on who and what the scholarship may be awarded to including the nationality, home institution, and course being taken. The Education Director determines the amount and if a student is eligible for a scholarship according to these limitations. Awards are first used to cover tuition costs and then room and board and travel expense if the amount awarded allow this.

F990_P06_S0A_L06	Form 990, Part VI, Section A, Line 6	Under the bylaws in effect in 2012, there were 352 Corporation Members who were nominated by the Science Council and elected at the annual or special meeting by the members to serve until death or resignation. The Corporation Members had limited voting rights regarding changes in the Bylaws. Bylaw amendments, which have been made by the Board, could be amended or repealed by the Members at a properly called meeting. Specifically reserved to the Members was the power to amend the sections of the Bylaws related to removal of Trustees and Bylaw amendments, and any other provisions of the Bylaws (or as required by law or the Articles of Organization) that require action by the Members. (These provisions were amended in 2013.)
F990_P06_S0A_L07a	Form 990, Part VI, Section A, Line 7a	Under the bylaws in effect in 2012, the Corporation Members elected a Chair of the Science Council, who also was a member of the governing board. (These provisions were amended in 2013.)
F990_P06_S0A_L07b	Form 990, Part VI, Section A, Line 7b	As described above in the context of Part VI, Section A, Line 6.
F990_P06_S0B_L11b	Form 990, Part VI, Section B, Line 11b	Form 990 is prepared by the MBL staff and reviewed by Grant Thornton LLP, the institutions audit and tax services firm. A draft copy is then submitted to the Audit Committee of the Board of Trustees for a review. The final version is given to all members of the Board of Trustees at least five (5) days before the filing date.
F990_P06_S0B_L12c	Form 990, Part VI, Section B, Line 12c	The process in 2012 was that all employees of the MBL were annually sent the following from Human Resources: a link to the online MBL conflict of interest policy, a memo explaining the need for all employees to fill out the disclosure form, and the disclosure form. Human Resources ensured that all employees returned the form by the requested due date. The forms were reviewed and signed by the Human Resources Director. All forms with a potential conflict of interest were reviewed by the MBL President/Director. The Human Resources Director and the President/Director would attempt to resolve the conflict with the employee. Failure to comply with the policy could result in dismissal, subject to and in accordance with the terms of any applicable employment agreement. All MBL board members were sent a copy of the Trustee conflict of interest policy and a conflict of interest disclosure form to be filed within 30 days of election to the board and annually thereafter. The disclosure forms were received by the President/Director's office, and forwarded to the Chief Financial Officer. The forms were reviewed for possible conflicts of interest by the Chairman of the Board. If conflicts of interest could not be resolved or the board member failed to comply with the policy, the board member could be subject to removal by a vote of the board pursuant to the bylaws. (The process for review of employees and board members was changed in 2013.)
F990_P06_S0B_L15	Form 990, Part VI, Section B, Line 15	The previous President/Director's compensation package for 2012 was determined and approved by the Board of Trustees after review of comparable salaries & benefits in the industry using at least two sources of data.
