Desc	Visitor Services Brookfield Zoo served over 2.1 million visitors in 2015, providing them with transportation, shops and restaurants. In addition to motorized, narrated educational tours throughout the park, the Zoo offers strollers, wheelchairs, wagons, etc. to help visitors have a more enjoyable visit. The shops make available goods which promote an interest in and understanding of the natural world and an awareness of how people around the world co-exist with the animals and the ecosystems where they live, and how choices made by humans impact the animals and the environment. The restaurants allow our visitors to stay in the park for lunch and expand the time they can enjoy the park. Visitor Services works closely with educators and designers to develop food packaging programs and select products which convey education and conservation related messages. Visitor Services also provides opportunities for families, businesses, senior groups, social clubs, etc. to hold special outings at the park where they receive admission, special tours and interaction with zoo staff.

Explanation	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 Cook County 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.

I 5 and 6	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.
III 1A	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.
III 4	The more than 2500 ambassadors of the animal kingdom which make up the CZS collection provide our visitors a rare opportunity to see species from around the globe. The collection, in connection with our education programs, provides CZS the opportunity to teach guests about animals and nature, conservation and other related topics.
V 4	The Societys endowment consists of 11 different funds established to support a variety of CZS programs including conservation and research, education and outreach, care of the animal collection and grounds, and general operations. Additionally, the Society is the designated beneficiary of the interest income on a 1 million endowment established and maintained by the Chicago Community Trust. The CCT maintains variance power over this endowment and, accordingly, the Society has not included it in its financial statements.
VI 1A-E	The Society operates a zoological park on land owned by the Forest Preserve District of Cook County, IL which is provided to the Society at no charge. The land site of the Zoo, accordingly, is not recorded on the Societys financial statements. All park improvements acquired by the Society are legally owned by the District. All park improvements acquired by the Society, including those acquired with District funds, are recorded as park improvements on the Societys financial statements. The amount in Other represents construction in progress on capital assets. Once a capital asset is complete and in use, the total amount for that project is closed out of construction in progress and transferred to park improvements.
X 2	The Societys application of accounting principles generally accepted in the United States of America GAAP regarding uncertain tax positions had no effect on its financial position as management believes the Society has no material unrecognized income tax benefits, including any potential risk of loss of its not-for-profit status. The Society would account for any potential interest or penalties related to possible future liabilities for unrecognized income tax benefits as income tax expense. Management believes the Society is no longer subject to examination by federal, state, or local tax authorities for periods before 2012.

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 approximately 20 reviewers. All proposals must be endorsed by an IUCN Species Survival Committee or other major, internationally known conservation organization, the AZA/WAZA, or other major zoo organization.

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 CBT ESF Committee members. Status reports are required from recipients 6 months after the receipt of the funds.
