      <Desc>Park Operations The CZS maintains 75 buildings on 214 acres of land to exhibit over 2,500 animals. In a typical year, two million visitors annually enjoy the experience of seeing and learning about the animals of the world. Each individual that enters through Brookfield Zoos gates represents an opportunity to introduce representatives of the wild world, to convey our intertwined connections to the animal kingdom, and to encourage positive change in the world. The Zoo is open every day of the year. Admission is free to the general public 52 days/year and at all times to Illinois school groups and military personnel. The membership team services our 111,000 member households, providing them with the opportunity to participate in the conservation and educational efforts of CZS.

        <Desc>Center for Science and Animal Well-Being CSAW More than 2500 ambassadors of the animal kingdom provide our visitors with a rare opportunity to see species from around the globe and experience up close, personal encounters with some. Expert care of these ambassadors is a time-honored tradition at CZS, where innovations in husbandry techniques and pioneering breeding programs are part of the cuttting edge culture of excellence. CSAW staff integrate disciplines such as population biology, behavioral science, nutrition and veterinary science to determine the best ways to provide and continuously care for the animals. They also incorporate models and practices from around the world, and from an array of animal care professionals, to develop the best possible zoo-based animal care and management practices. Through Keeper Chats and Ambassador Animal Encounters, CSAW staff share their knowledge of the animals in their care with zoo guests, helping them gain an appreciation for all citizens of the natural world.</Desc>

        <ExplanationTxt>The Chicago Zoological Society is a private non profit organization that operates Brookfield Zoo on land owned by the Forest Preserve District of Cook County. Brookfield Zoo was created through an act of the Illinois Legislature and the Society annually receives partial funding from the Cook County Forest Preserves to maintain and operate the Zoo. Occasionally, the laws and regulations under which the Society was organized and is funded and operated require updating. The Society may advise and assist appropriate legislative bodies in this activity. It may also advocate the adoption or rejection of legislation. By virtue of a management agreement with the District, the Society is periodically called upon to advise on matters of public policy. The Society also employs certain staff and consultants to communicate with the State of Illinois, federal officials, county commissioners and other government officials, to inform those parties of the activities of the Society. Additionally, as required during the year, the Societys President and designated staff attend national and international professional group meetings and otherwise communicate with those groups on various matters, including the expression of opinions to appropriate congressional representatives, congressional committees or other deliberative bodies that influence public policy concerning species in danger of extinction, environmental management, the biological sciences and kindred subject, and federal regulatory agency activities affecting wildlife and its management. Also, as needed from time to time, the Society may contact its members, staff and volunteers to encourage them to express their views on pending legislation that may have a direct impact on the Society and its conservation programs. In FY22, the Society engaged in a county-wide referendum effort, which required the investment of additional funding and staff time.</ExplanationTxt>

        <ExplanationTxt>The Society does not maintain any donor advised funds. Other Funds consist of the Chicago Board of Trade Endangered Species Fund and the CZS Womens Board Fund. Contributions to these funds come from donors as well as proceeds from fundraising events and investment income. Grants are decided by committees as described in Schedule I. At times, donors who have given money to the fund may also sit on the granting committee but no one donor may decide on the grant awards. All grants awarded must follow the guidelines and processes established by CZS. CZS Board of Trustees has final approval of all Chicago Board of Trade Endangered Species Fund Committee recommended grant awards. CZS Management has final approval of all CZS Womens Board recommended grant awards.</ExplanationTxt>

        <ExplanationTxt>Animal Collections, which were acquired through breeding loans, purchases and contributions, are not recognized as assets on the Statement of Financial Position. Costs to acquire collection items are recorded as decreases in unrestricted net assets in the year in which the animals are acquired. Proceeds from deaccessions are reflected as increases in the appropriate net asset class. The Societys animal collection consists of specimens with numerous attributes including taxonomic group, age, sex, relationship and value to other animals, endangered status and breeding potential. The Society retains a record of every animal in a permanent file. An inventory of the collection is prepared annually. Professionally trained keeper staff and population managers provide daily care for the collection and determine population needs.</ExplanationTxt>

        <ExplanationTxt>The Society awards grants through its Chicago Board of Trade Endangered Species Fund CBT ESF. The grant cycle is 2 times per year. Grant proposals are reviewed by a team of four. Proposals may be endorsed by an IUCN Species Survival Committee or other major, internationally known conservation organization, the AZA/WAZA, or other major zoo organization. For any individuals/organizations who are not US Citizens/entities, the Society checks the most recent OFAC Control List of Specifically Designated and Blocked Persons as well as the Consolidated List established and maintained by the 1267 Committee with respect to Al-Qaida, Osama Bin Laden, and the Taliban and other individuals, groups, undertakings and entities associated with them. Approximately 50,000 is awarded each cycle, usually in amounts of 2000 to 5000 per grant. Final award recommendations are presented to the Executive Committee of the Board of Trustees by the CBOT Committee members. Final reports are due 1 year after the receipt of the funds along with a final accounting of the grant funds expended. In addition, other grant funds are given by the Society to major, internationally known conservation organizations in support of their general conservation mission. These contributions are determined by Society management. They are approved by the Board either as part of the annual operating budget process or as part of a periodic spending authorization from the Societys Board Designated Conservation Fund.</ExplanationTxt>
