“A draft of the 990 and related schedules are emailed to all members of the audit committee for review. Upon confirmation that the audit committee does not recommend any further changes, the return is provided to the entire governing body prior to filing.”
“The foundation's conflict of interest policy must be consulted and satisfied prior to entering into any transaction or arrangement covered by the policy. Potential conflicts are reviewed by the non-conflicted trustees or committee members, and they shall decide if a conflict exists. If a conflict is determined to exist, the foundation will explore conflict-free options, and if such options are feasible, then the disinterested trustees vote on whether or not to enter into the conflicted transaction or arrangement. The officers, trustees and employees of the foundation annually acknowledge the policy and disclose any interest which may be in conflict in writing.”
“For all senior management positions, the foundation consults market surveys, and employs comparability analysis in the determination of appropriate compensation. The board approves the ceo's compensation.”
“The foundation maintains a copy of its form 990 on its own website, located at www.franklloydwright.org, as well as listing it on guidestar.org. The return is always immediately available upon request. The foundation's annual report is posted on the company website and includes financial information. The website also includes the foundation's mission and vision statement, and listings of the board of trustees. All governing, taxation and financial documents, required to be made public, are available upon written, e-mailed or telephone request, or if requested in person, at the company's headquarters in scottsdale, arizona.”
“The foundation received an employee retention tax credit during 2022-23 for the second and third quarters of 2020. The amount of the credit is not being included in revenue for 2022-23 but instead is being shown as a prior period adjustment in part xi, line 8.”
“The conservation and historic structure easements were put in place by the foundation on property where title was already held. The expenses associated with placing the easements were expensed as incurred. The real properties upon which the easements were placed are carried on the foundation's books at historic cost.”
“The majority of the collections are personal artwork and decorative items acquired by the late frank lloyd wright. The collections are available by appointment for research, exhibition and publication.”
“The endowment funds are comprised of funds for three purposes: 1) a fund the purpose of which is to conserve the taliesin property; 2) two funds the purpose of which are to support two staff positions in the foundation's preservation department.”
“The foundation is organized as an arizona nonprofit organization and has been recognized by the internal revenue service (irs) as exempt from federal income taxes under section 501(a) of the internal revenue code as organizations described in section 501(c)(3) and has been determined not to be a private foundation under section 509(a)(1). The foundation files annually a return of organizations exempt from income tax (form 990) with the irs. In addition, the foundation is generally subject to income tax on net income that is derived from business activities that are unrelated to its exempt purpose. The foundation believes that it has appropriate support for any tax positions taken affecting its annual filing requirements, and as such, does not have any uncertain tax positions that are material to the financial statements. The foundation would recognize future accrued interest and penalties related to unrecognized tax benefits and liabilities in income tax expense if such interest and penalties are incurred.”
