“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 organization's officers review competitive salary data. Each employee undergoes an annual review led by the organization's officers and directors. These officers and directors meet to discuss compensation for all non-officer employees based on their job duties, performance, competitive salary data, and cost of living adjustments. The ceo sets the salary for the coo and cfo. The board of directors (excluding the ceo) determines the salary of the ceo.”
“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.”
“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.”
