        <Explanation>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 300 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 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 Association 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.</Explanation>

        <Explanation>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. The Museum's unrelated business income tax is limited and no tax provision has been made in the accompanying financial statements. The Museum accounts for the effect of any uncertain tax positions based on a "more-likely-than-not" threshold applied to the likelihood of positions taken or expected to be taken in a tax return being 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 tax liability for all uncertain tax positions. The Museum has identified 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 tax positions and has determined that such tax positions do not result in an uncertainty requiring recognition. The Museum is not currently under examination by any taxing jurisdiction. The Museum's Federal and state tax returns are generally open for examination for three years following the date filed.</Explanation>

        <Explanation>The Museum of Science is the flagship site for the Intel Computer Clubhouse Network, which includes sites both within and outside the US. The Museum's primary role is to advise and to coordinate communication and cooperation between sites, but each site is an independent entity. The Museum will occasionally provide pass-through funding from Intel to help in establishment and upgrade Clubhouse sites, and also provides travel support for representatives from sites to attend the network Annual Meeting and the biennial Teen Summit, an event that includes opportunities for Clubhouse youth to express themselves using graphic design, video animation, digital art, music, radio, documentary film-making, and 3-D modeling. The Museum's other major grant-making role in the Network is to pass through Intel funding for Clubhouse to College scholarships. Scholarships are awarded through an application process which includes review by staff of the Clubhouse Network, a representative from MIT, a representative from Intel, a Museum staff person not directly associated with the Clubhouse program and has also included mentors and staff from around the Network. Scholarships are paid to the Clubhouse site or to the school attended, not to the individual student. For all types of funding, recipient sites are required to provide narrative and financial reporting to the Museum to ensure proper use of funds. Sites that have demonstrated an inability to perform adequate administration of grant funds are not eligible for future funding, although they may continue to participate in the network in other ways. All sites are required to be legally recognized as charities in their home jurisdictions as a condition of network membership.</Explanation>

        <Explanation>GRANT-MAKING: Grant-making expenditures outside the United States are directly accounted for on the Museum's financial statements as program expenditures not distinguished in any way from similar grants made to recipients within the United States. 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 be added to the Museum's own offerings. Staff also introduce other institutions to programs and materials the Museum has already developed. Costs associated with such travel are accounted for under the same accountable plan as the Museum's domestic travel.</Explanation>

        <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. In cases such as direct mail where costs other than the fundraising services are incurred (such as postage, printing, etc.), the company's invoicing is in sufficient detail to allow the Museum to track and code those expenses separately from the amounts reported as "professional fundraising fees" on From 990, Part IX, Line 11e. For the companies listed in Schedule G, those additional expenses totaled $10,212. All agreements with outside fundraisers provide for invoicing of the Museum based on solicitations made, rather than withholding of amounts from funds raised. No outside fundraiser has custody of any funds raised.</Explanation>

        <Explanation>CASH GRANTS: The Museum's cash awards fall into four 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 OMB Circular A-133. B) Prizes and awards - The Museum administers two annual awards for the recognition of scientific publication and communication. As 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. D) Computer Clubhouse Network support - These are 2 classes of payments made to or on behalf of member sites in the Intel Computer Clubhouse Network, of which the Museum is the flagship site. The Museum's primary role is to advise and to coordinate communication and cooperation between sites, but each site is an independent entity. The Museum occasionally provides pass- through funding from Intel to help establish and upgrade Clubhouse sites, and also provides travel support for representatives from sites to attend the network Annual Meeting and the bi-ennial Teen Summit. The Museum also passes through Intel funding for Clubhouse to College scholarships. Scholarships are awarded through an application process which includes review by staff of the Clubhouse Network, a representative from MIT, a representative from Intel, Museum staff people not directly associated with the Clubhouse program and has also included mentors and staff from around the Network. For travel stipends and other support of Clubhouse sites, the Museum requires both narrative and financial reporting to ensure funds are used appropriately. For scholarships paid on behalf of individual students from Clubhouse sites, checks are issued directly to the college being attended, rather that to the student, to ensure use of the funds for the purpose intended. 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.</Explanation>

        <Explanation>The Museum provides to its President and Director two forms of compensation not available to other employees. Due to the significant amount of travel undertaken by the President and Director on behalf of the Museum, travel costs for his wife are sometimes provided in cases where the nature or purpose of a trip is such that accompaniment by a spouse is expected or customary. Amounts provided under this arrangement are reported on Form W-2 as appropriate. The Museum also provides college tuition, room, and board for the President and Director's children, grossing up the payments to offset the related tax obligations. These payments are included in Part II Column (B)(iii) Other reportable compensation.</Explanation>

        <Explanation>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/Director for any salary increases. In addition, the Committee reviews the performance and compensation of the President/Director 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 Vice President of Human Resources though a variety of resources. These resources include an outside survey group used to benchmark each of the senior management positions including the President and Director 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.</Explanation>

        <Explanation>Upon election/hiring, and annually thereafter, all Museum Trustees, Overseers (an advisory, but non-governing body), and Key Employees are required to fill out a detailed Conflict of Interest form which solicits detailed information about associations with companies, organizations, and each other that may represent a conflict of interest with respect to the Museum. The forms are reviewed at least annually by both the CFO and staff of the Museum's Accounting department to identify any reported conflicts which may require disclosure and/or further follow-up. With respect to business relationships with 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 other, nonrelated, firms.</Explanation>
