Governance Explanations

Form 990, Part VI, Section A, Line 7A

Members of the suffolk county vanderbilt museum board of trustees are appointed by the suffolk county legislature. The museum's board of trustees sometimes make appointment recommendations to the suffolk county legislature.

Form 990, Part VI, Section A, Line 7B

The management of the vanderbilt endowment fund resides with suffolk county.

Form 990, Part VI, Section A, Line 8B

The only committee who has written minutes is the education committee. All other committees do not regularly provide written minutes.

Form 990, Part VI, Section B, Line 11B

The suffolk county vanderbilt museum has its form 990 prepared by an outside accounting firm and has established the following review process to ensure that the information reported is complete and accurate. When the form 990 has been prepared and reviewed by the executive director, it is distributed electronically to members of the organization's governing body for their review prior to its submission to the internal revenue service.

Form 990, Part VI, Section B, Line 12C

The conflict of interest policy is enforced by the legislature through a rigorous series of interviews before a candidate for trusteeship is recommended. The parks and recreation committee of the vanderbilt has a formal hearing, which must be attended by the candidate. At that time questions concerning conflicts may be raised. A vote is taken and if passed, a resolution appointing the candidate is voted by the full county legislature. Political conflicts are addressed in county code, as well as in museum policies. Monitoring of potential conflicts is provided by the ongoing oversight of board committees, particularly the finance and education/collections committees. The county oversight committee, as well as the budget review offices of the legislature and county executive's office, also monitor for conflicts of interests.

Form 990, Part VI, Section B, Line 15A

The compensation of the executive director is an annual salary determined by the board of trustees. It is based on aam and new england museum association published salary surveys of museum personnel, as well as area comparable and most importantly, the museum's budgetary needs.

Form 990, Part VI, Section C, Line 19

Financial information is available on-line through the suffolk county legislative website. All minutes to monthly board meetings are available on-line and contain museum policies.

ALSO INCLUDED ARE COSTS RELATING TO THE GROUP TOURS OF THE GROUNDS AND ADMISSIONS TO THE MUSEUM. EAGLE'S NEST IS THE SUMMER HOME OF WILLIAM K. VANDERBILT II, THE GREAT-GRANDSON OF CORNELIUS VANDERBILT. LISTED ON THE NATIONAL REGISTER OF HISTORIC PLACES, EAGLE'S NEST WAS BUILT INITIALLY IN 1910 AS A SMALL ENGLISH COTTAGE. OVER THE NEXT 30 YEARS, THE HOUSE GREW INTO THE SPRAWLING 24 ROOM SPANISH-REVIVAL MANSION THAT IS SEEN TODAY. EAGLE'S NEST WAS DESIGNED BY FAMED ARCHITECTS WARREN AND WETMORE, WHO TOOK INSPIRATION FROM THE ARCHITECTURE OF SPAIN AND NORTHERN AFRICA, AND ADORNED WITH IRONWORK MADE BY MASTER CRAFTSMAN SAMUEL YELLIN. UNIQUE AMONG MANY MANSIONS, EAGLE'S NEST WAS NOT ONLY BUILT WITH LIVING SPACE FOR MR. VANDERBILT AND HIS FAMILY, BUT ALSO MUSEUM SPACE WHERE VANDERBILT COULD SHOWCASE THE THOUSANDS OF NATURAL HISTORY AND CULTURAL SPECIMENS HE HAD COLLECTED FROM HIS TRAVELS. THE MANSION'S LIVING QUARTERS OFFERS AN INTIMATE LOOK AT THE LIFE OF A PRIVILEGED FAMILY FROM THE JAZZ AGE THROUGH THE SECOND WORLD WAR. THE ROOMS ARE AS WILLIAM AND ROSAMOND VANDERBILT LEFT THEM, FILLED WITH PRICELESS ART, FURNISHINGS, AND PERSONAL POSSESSIONS. WHEN VISITORS WALK THROUGH THE VANDERBILT MANSION, THEY ENTER A "LIVING MUSEUM," AN ENCHANTING TIME CAPSULE OF A VANISHED ERA. MR. VANDERBILT'S OCEANIC EXPEDITIONS AND UNPRECEDENTED CIRCUMNAVIGATIONS OF THE GLOBE MAKE IT POSSIBLE FOR VISITORS TO JOURNEY AROUND THE PLANET WITHOUT LEAVING LONG ISLAND. HIS SPECIMEN-HUNTING TRIPS TO THE GALAPAGOS ISLANDS, THROUGHOUT THE PACIFIC, ASIA, THE MEDITERRANEAN, AFRICA, THE ATLANTIC AND CARIBBEAN, YIELDED THOUSANDS OF SPECIMENS OF MARINE, BIRD AND INSECT LIFE, SOME OF THEM NEW DISCOVERIES AT THE TIME VANDERBILT FOUND THEM. WANTING TO SHARE HIS COLLECTION WITH THE WORLD, MR. VANDERBILT CONSTRUCTED SEVERAL MUSEUM SPACES THROUGHOUT THE ESTATE. TODAY, VISITORS CAN EXPLORE 4 SEPARATE WINGS TO SEE THESE COLLECTIONS. THESE WINGS ARE AS FOLLOWS: THE MEMORIAL WING, THE HABITAT WING, THE NURSERY WING, AND THE HALL OF FISHES.
