        <ExplanationTxt>In accordance with SFAS 116, the Society has elected not to report collection items in its Statement of Financial Position or Statement of Activities. Collection items acquired either through purchase or donation are not capitalized. Purchases of collection items are recorded as a decrease in unrestricted net assets if purchased with unrestricted assets and as decreases in temporarily restricted or permanently restricted net assets if purchase with donor-restricted assets. Contributions of collection items are not recognized in the Statement of Activities. The Society has a policy that requires net proceeds realized from the sale or transfer of deaccessioned objects will be used only for acquisition and conservation of collections. The Society's collections include books, manuscripts, photographs, research materials and objects relating to the history of New Hampshire. These collections have been acquired by donation, bequests, and purchases. Collection items are acquired or conserved based on the Society's long-range plans for collections development. Collections are made available for scholarly use by the public and maintained under appropriate security and preservation conditions.</ExplanationTxt>

        <ExplanationTxt>The Society adheres to the Other Presentation Matters section of the Presentation of Financial Statements for Not-for-Profit Organizations topic of ASC 958-205-45. ASC 958-205-45 provides guidance on the net asset classification of donor-restricted endowment funds for a nonprofit organization that is subject to an enacted version of the Uniform Prudent Management of Institutional Funds Act (UPMIFA). ASC 958-205-45 also requires additional disclosures about an organization's endowment funds (both donor-restricted endowment funds and board-designated endowment funds) whether or not the organization is subject to UPMIFA. The Board of Trustees of the Society has interpreted UPMIFA as allowing the Society to appropriate for expenditure or accumulate so much of an endowment fund as the Society determines is prudent for the uses, benefits, purposes and duration for which the endowment fund is established, subject to the intent of the donor as expressed in the gift instrument. The Society's endowment funds consist of both donor-restricted endowments and unrestricted, board designated net assets. Accordingly, income from the Organization's endowment funds consists of revenue streams that are both available for general expenditure, as well as other revenues that are purpose, use, and/or term restricted. The restriction imposed on income from the endowments depends on the underlying funds that such revenue is generated from, and any applicable restrictions imposed on those investments. As part of the Society's liquidity management, it has a policy to structure its financial assets to be available as its general expenditures, liabilities, and other obligations come due. In addition, the Society has board designated endowment of $9,490,526. Although the Society does not intend to spend from its board designated endowment other than amounts appropriated for general expenditure as part of its annual budget approval and appropriation process, amounts from the board designated endowment could be made available if necessary. In accordance with UPMIFA, the Society considers the following factors in making a determination to appropriate or accumulate donor-restricted endowment funds: (1) the duration and preservation of the various funds, (2) the purposes of the donor-restricted endowment funds, (3) general economic conditions, (4) the possible effect of inflation and deflation, (5) the expected total return from income and the appreciation of investments, (6) other resources of the Society, and (7) the investment policies of the Society. The majority of the Society's designated funds for endowment are to be used for: general operations; museum acquisitions and conservation; library acquisitions and conservation; publications; educational programs and services; and building improvements and repairs.</ExplanationTxt>

        <ExplanationTxt>The Society is a not-for-profit organization exempt under Section 501(c)(3) of the Internal Revenue Code and is classified as other than a private foundation; however, certain unrelated business income is subject to federal taxation. For the year ended September 30, 2022, there was no liability for a tax on unrelated business income. The Society has adopted the provisions of ASC 740, Accounting for Uncertainty in Income Taxes. Accordingly, management has evaluated the Society's tax positions and concluded the Society had maintained its tax-exempt status, does not have any significant unrelated business income and had taken no uncertain tax positions that require adjustment or disclosure in the financial statements. With few exceptions, the Society is no longer subject to income tax examinations by the U.S. Federal or State tax authorities for years before 2019.</ExplanationTxt>

        <ExplanationTxt>The Executive and Compensation Committees of the Society strive to ensure that the process for determining the compensation and benefits offered to the top officials and executives of the New Hampshire Historical Society is efficient, effective, and ultimately serves the public and furthers the Society's mission. The Institution adheres to good governance practices in establishing executive compensation. The Executive Committee serves as the Compensation Committee of the Society and makes recommendations to the full Board of Trustees in matters of the President's terms of employment, including compensation and benefits. The compensation and benefits of the President are set forth in either a written compensation and benefits term sheet, or in a formal written employment agreement executed between the Society and the President. The Executive Committee will submit the recommended compensation term sheet or formal employment agreement with the President to the Board of Trustees for discussion and action. The Board and Executive Committee discuss the matter during a portion of the board meeting when the President is excused from the meeting and not present. The term sheet or formal agreement with the President must be approved by a majority vote of the Board of Trustees present at a duly called and held Board of Trustees meeting where the required quorum of Directors is present to conduct a meeting. Comparisons of public data on compensation are used and documented in determining the President's compensation, as well as facts and circumstances relating to the past performance of the President. The President's compensation package is reviewed regularly by the Board of Trustees. The President of the Society is responsible for all administrative details and for the implementation of policies, programs, and long range objectives approved by the Board of Trustees, including compensation and benefits offered to officers and senior managers. The President exercises full supervision and management of all personnel, assigns duties, and so forth within the policies approved by the Board. Compensation for senior managers is determined through a due diligence process that the President employs based upon the comparisons of public data, particularly the published wage scales of the New England Museum Association, past performance, and the ambitious goals stated in senior managers' annual work plan objectives. Overall compensation is reviewed by the Finance Committee and a recommendation is made to the Board of Trustees for their approval as part of the annual budget process.</ExplanationTxt>
