“The full board of directors receives the 990 one week prior to filing.”
“Each year at the fall board meeting, each board member reviews the conflict of interest policy and signs a conflict of interest statement. Board members have access to the policy throughout the year.”
“The planetary society uses third-party market rate data for all employee positions and sets compensation based on those data. Each employee sets performance goals at the beginning of each year and undergoes a performance review led by their supervisor at the end of each year. Any change in base compensation requires a change in market rate along with performance measures being met. The board of directors (excluding the ceo) uses market data and performance measures to determine ceo compensation.”
“Governing documents, conflict of interest policy, audited financial statements and irs form 990 are available upon request. Documents can be viewed at our office, mailed, or e-mailed to the requesting party. Audited financial statements and irs form 990 are also published on the society's website.”
“Other professional fees: program service expenses 463,683. Management and general expenses 33,285. Fundraising expenses 332,834. Total expenses 829,802.”
“Endowment earnings are to support the operations of the organization”
“The accounting standard on accounting for uncertainty in income taxes provides guidance on how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. Examples of tax positions include the tax-exempt status of the society and various positions related to the potential sources of unrelated business taxable income (ubit). The society believes that it has no uncertain tax positions that impact its financial statements.”
