      <Description>Animal Care and ResearchDenver Zoo is home to 3,800 animals representing more than 650 species and is accredited by the Association of Zoos and Aquariums (AZA). AZA accreditation assures the highest standards of animal care. A leader in environmental action, Denver Zoo is dedicated to ensuring the safety of the environment in support of all species and is the first U.S. zoo to receive ISO 14001 certification for the entire facility and operations. The international certification ensures the Zoo operates in accordance with the most rigorous environmental standards. In September 2011, the Association of Zoos and Aquariums awarded Denver Zoo its inaugural Green Award, recognizing Denver Zoo's national leadership and commitment to sustainable design, construction, and operations. The Zoo's Conservation/Biology Department is dedicated to field research and animal conservation projects around the globe. Since the Department was created in 1996, the Zoo has participated in hundreds of projects in 55 countries on five continents (Africa, Asia, Europe, North America and South America). Conservation projects focus on key species and landscape conservation planning, a widely-accepted method of conserving large ecological systems. Projects in Mongolia, Kenya, Peru, Vietnam, Indonesia and the western United States were a focus in 2011.</Description>

        <Description>Zoo ImprovementsZoo Improvements includes a combination of large and small capital projects. The largest component is $22,333,006 towards the completion of Toyota Elephant Passage, as part of the Millennium plan. Expenditures for this $50M capital project are expensed since the City and County of Denver will own the assets upon completion in 2012. Approximately $1,300,000 of this expense is associated with the refurbishment of the Northern Shores cafe and the surrounding area. The cafe was upgraded with a new kitchen and equipment. A playground was built next to the cafe with a subarctic landscape theme that incorporates a climbing feature and an interactive water feature. Smaller capital projects include critical investments in equipment and facilities to maintain the Zoo. These projects generally include improvements for both animal and visitor safety, and new equipment including autos and machinery. A portion of this expense was made for the Zoo's share of the a new VOIP telephone system which will be completed in 2012.</Description>

        <Description>Environmental/Conservation Education ProgrammingEducation is a major focus for Denver Zoo, with a variety of programs available for diverse audiences, both at the zoo and at schools and other locations throughout the Denver metro area. The zoo reaches out to diverse audiences, especially underserved populations that historically have not participated in programs offered by scientific and cultural facilities. We have strategically sought collaborations with partners that have earned the trust of underrepresented audiences. In 2011, approximately 50,000 students participated in on-site classes, assemblies, science workshops, career programs, our popular Bunk with the Beasts program, Summer Safari (a day camp) and other programs. This number does not include students who visited the zoo on field trips. 85,479 children and adults participated in education outreach programming, primarily Pre-K through 12th grade students.</Description>

        <Description>Other Programs includes: Certificates of Participation, Member Services, Guest Services, Horticulture and Interns. Certificates of Participation is an account funded by $1.00/per paid admission and is used to reimburse the city for providing $8.5 million of the balance of parking garage construction expenses in 2001. Member Services includes the expenses associated with obtaining new members and retaining our 57,700 household members. Guest Services is the department that provides all aspects of customer service from guest relations staff to security for the approximately 2,000,000 on-grounds visitors. The Horticulture department maintains all landscapes, grounds, and irrigation for the entire Zoo, including animal exhibits. The internship program is for college students who are working towards a degree in a field related to their area of interest at the Zoo.</Description>

        <Explanation>There are several factors, monetary and nonmonetary, that are considered in determining executive compensation. These business-related factors include: Budget: Does the budget allow for any flexibility in the offer and what is the relative financial health of our organization? Internal equity: What are other executives in the same type of job or at the same job level being paid? Market price/external demands: Is this job difficult to fill or is it hard to find qualified candidates in this location or industry? Candidates' level of experience: How many years of relevant experience does this person bring to the table? Candidates' education level: What degrees does the person have that will benefit our organization? Candidates' current compensation package: What is this person's current base pay and benefits package? Salary surveys: What are other executives in the same type of job being paid at other non-profit organizations of the same size? Once the salary is determined, the executive committee (which consists of independent board members) reviews this information. Written employment agreements are also used.</Explanation>

        <Explanation>The Denver Zoological Foundation's Board of Trustees assume the responsibility for oversight of the audit of its financial statements and selection of an independent accountant. This process has not changed from prior years. Form 990, Part I, Line 19: The Denver Zoo's net loss for 2011 of ($18,863,419) resulted primarily from expenditures incurred during the year for zoo improvements. Under the Zoo's current Cooperative Agreement with the City and County of Denver, the Denver Zoo does not retain ownership to any improvements that the Denver Zoo constructs. As such, improvements completed by the Denver Zoo in 2011 totaling $24,931,149 were expensed. The Denver Zoo received bond proceeds from the City and County of Denver and raised matching contributions related to the improvements during 2011 and prior years.</Explanation>
