Return Reference	Explanation
Schedule D, Part III, Line 1	The Society owns numerous works of art accumulated over the years. Consistent with financial statement presentations followed by other institutions, primarily museums, the Society excludes the value of its works of art from the statements of financial position. The works of art are held for educational and exhibition purposes.
Schedule D, Part III, Line 4	The Detroit Zoo has a permanent art collection from artists in multiple mediums acquired for the purpose of interpreting the relationship of humans with animals through various cultures and times. The collection was begun with the understanding that art is a visual communication that records feelings, beliefs, and ideas which reflect the cultural context in which it was made, hence artist interpretations were chosen over literal depictions. In the Wildlife Interpretive Gallery, one contemporary piece is a transfer image of cave paintings done by the earliest known artists some 40,000 years ago. Michigan artists in the Wildlife Interpretive Gallery collection are: Rich Branstrom, Susie Colquitt, Laura Ford, Peter Hackett, Cathy Peet, and Ia Moua Yang. Other recognized artists include Larry Rivers and Alexis Rockman.
Schedule D, Part IV, Line 2b	The Detroit Zoological Society collects donations for the Amazon Rainforest Adopt-A-School program on behalf of CONAPAC, a Peruvian NGO. The Detroit Zoo holds funds for the Eastern Massasauga Rattlesnake Species Survival Plan organization and the Society staff are active members in this organization.
Schedule D, Part V, Line 4	The Detroit Zoological Society (DZS) endowments were established to provide a stable source of funding to help underwrite the programs and facilities of the Detroit Zoo and Belle Isle Nature Center. Monies placed in endowments are invested, with interest, and only distributed as dictated by the Society's endowment governing policy. Funds may be established by donors within each endowment. A named fund requires a minimum investment of $100,000 and the revenue may be restricted by the donors. The endowments (minimum of $1 million) of the Detroit Zoological Society include the following: The Berman Academy for Humane Education Endowment: the Berman Academy for Humane Education Endowment was established September 13, 2001 by Madeleine and Mandell L. Berman. The purpose of the endowment is to support operational costs associated with humane education programs at the Detroit Zoo. The John S. and James L. Knight Fund: the Knight fund was established December 13, 1999 by the John S. and James L. Knight Foundation. The purpose of the fund is to support research and education programs of the Detroit Zoological Society. The Society determined that it would be most beneficial as a component of the Humane Education Endowment. The Adelyn B. Devereaux Fund: The Devereaux fund was established December 28, 2001 through Mrs. Adelyn B. Devereaux's trust agreement. The purpose of the fund is to benefit the Detroit Zoological Society's endowment fund. The Society determined that it would be most beneficial as a component of the Humane Education Endowment. The Richard and Jane Manoogian Endowment for Wildlife Art and Interpretation: the Richard and Jane Manoogian Endowment for Wildlife Art and Interpretation was established May 6, 2002 by Richard A. Manoogian. The purpose of the endowment is to purchase and maintain works of art, including sculpture, at the Detroit Zoological Park. In addition, earnings will support educational programs and projects focusing on the interpretation of art that explores the relationship between humans and animals.
Schedule D, Part X, Line 2	Summary of Significant Accounting Policies - Federal Income Taxes - The Society has been recognized by the Internal Revenue Service as an organization exempt from federal taxation under Section 501(c)(3) of the Internal Revenue Code (the Code). The Society is a public charity by reason of being described in the Code Section 509(a)(2). The Society is exempt from federal income taxes except to the extent of income derived from unrelated business activities. Unrelated business income is not material to the financial statements. The Society completed an analysis of its tax positions, in accordance with ASC 740, Income Taxes, and determined that no amounts were required to be recognized in the financial statements at December 31, 2022 or 2021.
Schedule D, Part XI, Line 2d	Other adjustments to audited financial statements include: donations to CONAPAC of $154,953, direct fundraising expenses of $489,453, and rounding of $1, for total of $334,501.
Schedule D, Part XII, Line 2d	Other adjustments to audited financial statements include: donations to CONAPAC of $154,953, and direct fundraising expenses of $489,453, for total of $334,500.

Explanation

Schedule J, Part I, Line 1a

The land, buildings, and animals of the Detroit Zoo are owned by the City of Detroit. A residential home is located on the grounds of the Detroit Zoo and the Executive Director was traditionally required to live in this residence. The residence is not considered taxable to the Executive Director, given that it was a requirement of the position. The DZS hired a new Executive Director in late 2021, as the previous Executive Director retired in December 2021. The requirement to live in this residence has been removed for the new Executive Director.

If the matters are material, the potential conflict would be brought to the attention of the Board. The Board Chair and/or the CEO, with the Board, will determine whether the contemplated transaction may be authorized as just, fair and reasonable to the Society. The decision of the Board Chair and/or the CEO of the Society on these matters will rest in their sole discretion, and their concern must be the welfare of the Society and the advancement of its purpose.
Form 990, Part VI, Section B, Line 15	The Detroit Zoological Society uses the AZA salary survey and engages an independent consultant to prepare a competitive salary analysis of non-union, salaried positions and develop salary structures and ranges for these positions.

If a new hire is to be brought in higher than the established midpoint wage of the pay grade and range, it must be approved by the HR Director and a member of the Executive Leadership Team. A salary is not to exceed the established maximum wage of the pay grade and range. Salary guidelines and wages are reviewed with the Compensation Committee of the Board.
