Schedule D, Part III, Line 1	Collections footnote: The Museum's collections consist of approximately 30,000 artifacts used primarily for educational activities, encompassing interpretations, discovery spaces, exhibits, lectures, classes, demonstrations, reference services, or other programs. The Museum also has a historical and archival collection that documents the history of the institution. The composition of the Museum's collections by artifact type is as follows: Natural Sciences 20,000 items; Cultural/Physical Science 5,000 items; Artwork 2,000 items; Institutional History 3,000 items; Archives 1,100 linear feet. The Museum's Collections Management Policy stipulates that the Museum will only acquire objects useful in fulfilling the educational purpose stated in its mission. The Museum accepts only those objects that can be immediately put on display in an exhibit, used in educational programs, or used in future programming. Items may be de-accessioned from the collections if they are determined to be no longer useful or relevant in assisting the Museum in fulfilling its mission. Consistent with the American Alliance of Museums' Code of Ethics, Museum policy specifies that proceeds from the de-accessioning of an item may only be used for the conservation or acquisition of other collections items. In accordance with current practice generally followed by museums, collections are not recorded as assets in the accompanying financial statements. Purchased additions to the collections are recorded as expenses at the time acquired. Although artifacts from the collections may from time to time be incorporated into exhibits, the Museum's exhibits themselves are not considered part of its collections and may be capitalized under the Museum's property, plant, and equipment policies. However, artifacts and artworks with a value of $250,000 or greater acquired specifically for incorporation into an exhibit and capitalized as part of that exhibit may be formally accessioned into the Museum's collections in order to be afforded the protections of the Museum's Collections Management Policy.
Schedule D, Part III, Line 4	The Museum's collections are used primarily for educational activities, encompassing interpretations, discovery spaces, exhibits, lectures, classes, demonstrations, reference service, or other programs. The Museum also has a historical and archival collection that documents the important and rich history of the institution. The Collections Department provides professional stewardship for artifacts that are temporarily in the custody of the Museum through loans and/or temporary exhibitions. Collections consist of: Natural Sciences - 20,000 items; Cultural/Physical Science - 5,000 items; Artwork - 2,000 items; Institutional History - 3,000 items; Archives - 1,100 linear feet. Living collections include approximately 250 indivdual animals and/or colonies representing 150 species either on ongoing exhibit or used in periodic educational demonstrations. The Museum also participates in endangered species breeding and care of injured animals which cannot be re-released into the wild.
Schedule D, Part V, Line 4	The Museum's endowment includes both donor-restricted endowment funds and funds designated by the Board of Trustees to function as endowments ("quasi-endowments"). The endowment consists of 119 individual donor restricted funds and 26 quasi-endowment funds used for a variety of purposes. These uses (as % of total value) include: Unrestricted/general operations - 18%, Exhibit construction and maintenance - 27%, Program support - 36%, Mixed use (primarily exhibits and programs jointly) - 12%, Other (including Library, Access, and Internships) - 8%
Schedule D, Part X, Line 2	The Museum's footnote disclosure with respect to FIN 48 is as follows: The Museum is exempt from income taxation on activities related to its charitable purposes under the provisions of Section 501(c)(3) of the Internal Revenue Code and is qualified to receive tax-deductible gifts and bequests under the U.S. tax code. The Museum is subject to tax on income from any business it conducts which is unrelated to its charitable purposes. These activities generally include event and conference services revenue for events of a purely social nature, rental income from parking spaces in the Museum's garage, investment income from certain endowment investments, and ticket income from non-scientific offerings in the Museum's planetarium and Omni theater. Taxes paid for these activities are recorded in the accompanying financial statements as expenses of the department generating the associated unrelated income. The Museum accounts for the effect of any uncertain tax positions on the basis of whether it is more likely than not that positions taken, or expected to be taken, in a tax return will be sustained upon examination by the relevant taxing authority. If a tax position or positions are deemed to result in uncertainties of those positions, the unrecognized tax benefit is estimated based on a "cumulative probability assessment" that aggregates the estimated liability for all uncertain tax positions. The Museum considers its status as a tax-exempt entity and the determination of income as related or unrelated to its exempt purpose to be its only significant income tax positions, and has determined that such positions do not result in an uncertainty requiring recognition. The Museum is not currently under income tax examination by any jurisdiction. The Museum's Federal and state tax returns are generally open for examination for three years following the date filed. The Museum is also responsible for calculating, collecting, and remitting sales and liquor taxes in various jurisdictions.

Explanation	PROGRAM SERVICES - SUPPORT FOR TRAVELING EXHIBIT: The Museum has developed The Science of Pixar traveling exhibition, and is touring two copies, one within the US and one internationally. Museum staff and contractors travel to host sites for exhibit installation, maintenance, and de-installation as the exhibit moves from site to site. Cost reported here also include maintenance and other activities conducted within the US in support of the international tour. PROGRAM SERVICES - TRAVEL TO CONFERENCES & PEER INSTITUTIONS: (Staff professional development and program dissemination): As the Museum expands its programming internationally, staff are increasingly called upon to travel to meetings and conferences in other countries, and to visit peer institutions to review programs and exhibits which may potentially inform the Museum's own offerings. Staff also introduce other institutions to programs and materials the Museum has developed. Finally, staff may travel internationally to perform research to inform the content of exhibits in development or to meet with non-US exhibit developers and fabricators. Costs associated with such travel are accounted for under the same accountable plan as the Museum's domestic travel. PROGRAM SERVICES - MEETINGS WITH VENDORS: Museum staff sometimes travels to consult with non-US-based vendors.	ExplanationTxt

Explanation	The Museum's use of external fundraisers may, in any given year, consist of a) general fundraising counsel, whose work is generally too integrated into the Museum's overall Advancement function to have "gross receipts" amounts specifically assigned; b) direct-mail companies, whose work ranges from simple large-scale mailing of materials developed and produced by the Museum itself to a more direct involvement in the design and creation of the solicitation materials; and c) telemarketers/text-messagers. Agreements with outside fundraisers generally provide for invoicing of the Museum based on solicitations made, rather than withholding of amounts from funds raised. Exceptions occur when the fundraiser provides a web portal for donors, in which case a fee is withheld from the donation and the proceeds forwarded to the Museum.	ExplanationTxt

Form And Line Reference	Schedule I, Part I, Line 2	FormAndLineReferenceDesc
Explanation	CASH GRANTS: The Museum's cash awards fall into three categories. A) Subawards under grants - These are monies passed through to institutions who have applied for government and private grants jointly with the Museum. The Museum monitors the subawardees' use of funds in accordance with the regulations governing such grants and the adequacy of this monitoring is audited annually under the provisions of 2 CFR 200. B) Prizes and awards - The Museum administers two major annual awards for the recognition of scientific publication and communication. The Museum also hosts refereed student competitions for which cash prizes are awarded. As all these awards are honoraria, monitoring of their use is not applicable. C) Stipends - These are payments to participants in professional development workshops offered by the Museum, or in pilot testing of Museum products and programs. As these payments are simple flat stipends based on number of workshop days, or on pilot test milestones, monitoring of their use is not applicable. NON-CASH GRANTS: The Museum also provides substantial non-cash "scholarships" for reduced-fee or no-fee participation in Museum programs for which a fee is usually charged. For these transactions, no funds are disbursed to the grantee; they are simply charged less, or not at all, for the program attended. Eligibility is determined in a number of ways, depending on the nature of the grantee. Schools are evaluated based on location in under-served neighborhoods or by percentage of free/reduced lunch program students. Community groups are evaluated on the basis of charitable status. Individual grantees are evaluated on the basis of income or residence in under-served areas. As the operation of these non-cash awards is entirely internal to the Museum, monitoring the use of the funds is also entirely internal and accomplished through the Museum's own accounting system.

Schedule J, Part I, Line 3	The Compensation Committee of the Museum's Board meets twice yearly, once in spring and once in the late summer or early fall. The first meeting is focused on establishing a recommendation to the Finance Committee that budgets for the upcoming fiscal year's museum-wide merit increase pool. The second meeting is focused on the review of the performance of Key Employees and other senior leadership staff for the prior year and to approve the recommendations of the President for any salary increases. In addition, the Committee reviews the performance and compensation of the President and recommends any adjustment to compensation if warranted. In order to do this in a fully knowledgeable manner, the Committee annually reviews information obtained by the Chief People Officer though a variety of resources. These resources include an outside survey group used to benchmark each of the senior management positions including the President against local non-profit organizations that are of a similar size. In addition, the Museum uses public resources such as Guidestar to access salaries of key people in Museums located in metropolitan areas. Finally, the Museum participates in and receives information from local and regional salary surveys of other museums in New England. This process gives a clear picture of local, regional, and national salary levels for its senior management. The Compensation Committee reviews this information in addition to the history of compensation increases, overall performance of the individual and of the Museum prior to approving or making recommendations for compensation increases.
Schedule J, Part I, Line 4	In 2021, Annette M Sawyer, SVP, Education, elected to take an early retirement package, which included severance payment of $123,076.80 during the tax year. In July 2021, Patricia Sheppard, VP of IT, resigned and received severance payments of $50,000.

After Audit Committee approval, the final version of Form 990 is provided to all members of the Museum's Board before the form is filed.
Form 990, Part VI, Section B, Line 12c	Upon election/hiring, and annually thereafter, all Museum Trustees, Advisors (an advisory, but non-governing body), and Key Employees are required to fill out a Conflict of Interest form which solicits detailed information about associations with companies, organizations, and each other which may represent a conflict of interest with respect to the Museum. The forms are reviewed at least annually by both the Assistant Controller, RF & Compliance and Interim VP Finance to identify any reported conflicts which may require disclosure and/or further follow-up. Using publicly available sources, additional research is undertaken by Museum staff to identify business and organizational associations which were not reported on the Conflict of Interest forms. With respect to business relationships between the Museum and companies associated with Trustees or Key Employees, it is the Museum's policy to subject such companies to the same procurement policies, procedures, and requirements as it applies to other, non-related, firms.
