      <Desc>Outdoor Program Centers - The Appalachian Mountain Club (AMC) manages more than 40 outdoor program centers and backcountry facilities, including lodges, mountain huts, full-service camps, cabins, shelters and campgrounds. These AMC facilities serve as a base for 4-season recreational activities, nature and environmental education courses, programs, scientific research, outdoor artistic pursuits, and other conservation-related activities. Visitors and overnight guests enjoy a broad range of walk-on programs, guided naturalist activities, outdoor recreational safety and skill building workshops, and backcountry activities to choose from. AMC facilities *Refer to Schedule O, Page 45 for Continuation*Outdoor Program Centers (Continued):are managed to reduce environmental impact by providing environmentally sensitive septic systems, composting, public drinking water, and overnight accommodations (some near treeline and in sensitive alpine areas) in areas where camping would have severe effects on the alpine plant life. The AMC facilities provide information and education on the local environment, recreational opportunities, outdoor safety, trails, and emergency shelter. The AMC staff also participates in search-and-rescue efforts throughout the White Mountains of NH and other regions. In 2018, The AMC provided 187,525 overnight guest accommodations at its facilities and information and other services to more than 2 million visitors.</Desc>

        <Desc>Membership - The Appalachian Mountain Club (AMC) members provide the grassroots network through which the AMC delivers its programming on a local level throughout our 12 state and district regions. The more than 280,000 members, advocates and supporters of the AMC provide a base of volunteers for trail projects, local clean-up and conservation projects, outdoor education and safety instruction. These members and volunteers organize and lead thousands of recreational outings and provide the local governance structure for the 12 local AMC chapters. Member dues and participation in the above mentioned activities provide a critical base of support for carrying out the AMC mission.</Desc>

        <Desc>Conservation Research and Policy - The AMC actively promotes the protection, enjoyment and understanding of the mountains, forests, waters and trails of the Appalachian region including critical areas of the four-state Northern Forest, the Mid-Atlantic Highlands of PA, NJ, NY, and CT, and Maine's 100-Mile Wilderness region. The AMC's Research and Policy Program conducts analyses of natural ecosystems to guide its efforts to protect these areas. This includes studying changes in land cover and land use and the impact on ecological and recreational resources; monitoring air quality and climate change impacts on Northeastern mountain ecosystems; analyzing in-stream flow criteria and hydroelectric dam operation impacts on river ecosystems and*Refer to Schedule O, Pages 45-46 for Continuation*Conservation Research and Policy (Continued):recreational resources; developing methods to reduce recreational user impacts on the region's mountains; and studying the benefits and impacts of different transportation options and energy sources, including renewable energy, on the ecosystems of concern to the AMC. Achievements are exemplified by the development and successful implementation of the recovery plan for an alpine plant formerly listed on the federal endangered species list, publication of a national award winning "Ecological Atlas of the Upper Androscoggin Watershed", adoption by states of elements of AMC's wind power siting guidelines and AMC's successful citizen science mountain monitoring program, Mountain Watch.The AMC's Research and Policy program also works with conservation partners and local communities to build grassroots support for priority conservation projects. The Research and Policy Program participates in and comments on formal resource management programs and decisions at the local, state, and federal level; consults with industry and land owners to find equitable solutions to environmental problems; advocates for state and federal land protection, clean air and energy policies, and trails funding, and facilitates member and public participation in local, state and federal environmental issues and policy.</Desc>

        <Desc>1. Education Program - The Appalachian Mountain Club (AMC) works with approximately 80,000 young people each year through guided and self-guided programs designed to make the outdoors and the environment accessible and meaningful to youth from all socioeconomic backgrounds. Our programs serve participants from Maine to New Jersey and include day and overnight school programs (grades K-12), walk-on activities offered to families coming through the AMC's huts and lodges, weekend long skill-based trainings, to one to three-week outdoor summer adventures. Across programs, hands-on experiences teach participants how to enjoy the outdoors through skills-building and improved understanding of the natural world as well as how to minimize their impact on the environment. AMC is also a national provider of Master Educator training in Leave No Trace principles. 2. Trails Program - AMC staff and more than 4,000 volunteers are engaged in on-the-ground recreation management and trail maintenance on 1,823 miles of trails, including more than 300 miles of the Appalachian National Scenic Trail in five states. Many of these trails are on public lands, including the White Mountain National Forest, Delaware Water Gap National Recreation Area, Acadia National Park, and state parks throughout the region. AMC offers a broad range of trail volunteer opportunities, including an adopt-a-trail program, teen trail crew programs, and volunteer vacations for adults interested in giving back through trail stewardship, amoung others. 3. Publications/Communications - AMC encourages safe and responsible outdoor recreation and environmental stewardship through a variety of publications, including our quarterly AMC Outdoors magazine, semi-annual Appalachia journal (the nation's longest running journal on mountaineering and conservation), and numerous retail books, maps, and field guides. Each publication stresses safety and stewardship and encourages volunteerism. Our website (www.outdoors.org) serves as an online resource for members and non-members seeking the latest information on outdoor adventures, lodging and program opportunities, backcountry conditions, volunteer opportunities, and outdoors skill-building.</Desc>

        <ExplanationTxt>The AMC Library &amp; Archives have been an integral part of the AMC since the AMC's founding year. They anchor a remarkable landscape in which the past lies alongside the present and future of the AMC and the Northeast outdoors. The Library's collection consists of over 2,500 monograph and serial titles. It represents one of the most extensive outdoor recreation book collections in the Northeast and counts among its holdings works on the history of mountaineering, early climbing expeditions, and early explorations. The book collection also contains a vast amount of background information on environmental issues and outdoor activities. At the center of the historical book collection is the Kilbourne Collection of over 500 books on the White Mountains of New Hampshire. Other mountain areas of the Northeast are also well documented. The library has no less than 22 titles on Mount Katahdin alone! The Archive's collection consists of meeting minutes, annual reports, AMC bulletins and journals, scrapbooks, climbing journals, manuscripts, summit registers, photographic works, films, memorabilia, and maps. Logbooks that are no longer sound enough to reside in the AMC's historic White Mountain huts can be found here, recording the thoughts and feelings of mountain travelers from decades past. The Archives are particularly rich in visual images, with well over 20,000 images covering the 1870's to the present. The library owns an extensive collection of lantern slides documenting the AMC's early history, and hundreds of postcards and stereograph cards with views of the mountains of the Northeast. The Frederick Endicott and Ralph C. Larrabee photo collections contain hundreds of photographs by these two local photographers of the White Mountains and Adirondacks taken between 1895 and 1935. The historic map collection consists of cartographer Edward G. Chamberlain's detailed maps and itineraries documenting the AMC outings from 1876 to 1935. Other maps include contemporary and historic maps of the Northeast, and those published in conjunction with our many guidebooks. The Library &amp; Archives are strongly linked to the AMC's mission. They help to build awareness of the AMC using the club's images and information in a wide range of publications, educational programming, and display materials. The Library &amp; Archives support the all departments in their historical documentation needs from preserving their departmental records to providing materials for AMC's magazine, journal, website, marketing campaigns, development efforts, programming, lodging, and the like. The long history of the organization that is housed by the Library &amp; Archives lends credibility and understanding to the Club's current organization and its initiatives.</ExplanationTxt>

        <ExplanationTxt>The purpose of the AMC's endowment funds is to serve as a perpetual source of financial support for the Club's programs and activities. The financial goal of these funds is to preserve their purchasing power by investing in a diverse portfolio of equity and fixed income securities while, at the same time, providing a reasonable level of annual cash flow to the Club. Permanently restricted endowment funds are subject to donor stipulations requiring such gifts be invested in perpetuity and only the income earned on the invested gifts can be expended. Use of term endowments proceeds are limited to either specific program activities or designated periods of time as stipulated by the donor. Board designated endowment funds, commonly known as unrestricted endowments, can only be expended pursuant to approval of AMC's Board of Directors.</ExplanationTxt>

        <ExplanationTxt>for AMC Maine Woods Funding, LLC (MWF) and AMC Maine Woods Initiative, LLC (MW Initiative): AMC Maine Woods Funding, LLC (MWF) and AMC Maine Woods Initiative, LLC (MW Initiative) are related organizations created and controlled by the AMC to secure long-term financing to carry out the AMC's Maine Woods Initiative program. The Maine Woods Initiative is the AMC's strategy for land conservation in the 100-Mile Wilderness region in Maine - addressing regional ecological and economic needs through outdoor recreation, resource protection, sustainable forestry and community partnerships. In August 2015, AMC Maine Woods Initiative, LLC, a wholly owned subsidiary of the Appalachian Mountain Club and a disregarded entity for tax purposes, was formed for the purpose of facilitating a $12.6 million financing structured under the New Markets Tax Credit ("NMTC") program of the U.S. Treasury Department. In conjunction with the NMTC financings, which occurred in September and October 2015, the assets of AMC Maine Woods, Inc. and AMC Maine Woods II, LLC, were transferred to AMC Maine Woods Initiative, LLC, and these entities were dissolved in December 2015. A note receivable was created as part of the financing structured under the New Markets Tax Credit ("NMTC") program of the U.S. Treasury Department and will be paid concurrent with the settlement of the corresponding loans payable mentioned below. In connection with these notes, AMC and an outside organization made contributions to AMC Maine Woods Funding, LLC, treated as a partnership under tax law, resulting in a 5% minority ownership by the outside organization. The above referenced loans payable are also part of a financing structure under the NMTC program of the U.S. Treasury Department. Loan proceeds are to be used for specified project expenses in Piscataquis County, Maine by the AMC's wholly owned subsidiary AMC Maine Woods Initiative, LLC. The loans are secured by certain assets. The loan and related agreements specify debt forgiveness provisions at maturity, and require the AMC to comply with certain covenants. In conjunction with the Loans Payable, single purpose lending entities were established by the lenders whose sole activities are the loans to the AMC Maine Woods Initiative, LLC. The AMC has entered into a put and call agreement with the lenders whereby the AMC may acquire the lending entities from the bank in 2022 or thereafter. It is expected that the AMC will acquire the entities in 2022 and will repay all amounts outstanding, less debt forgiveness amounts, at that time.</ExplanationTxt>
