“Prior to filing form 990, draft copies were distributed to the board of trustees. The draft copy was also reviewed and discussed at a meeting of the audit committee (the society's trustee executive committee.)”
“The trustees adopted a conflict of interest policy in 2007. The policy was expanded in 2010 to include key employees. The expanded policy requires an annual written disclosure document to be signed by each covered individual. The policy requires this process to be completed by the first trustees meeting following the annual meeting, which takes place in february.”
“Each year the trustees evaluate the compensation of the executive director objectively, taking into account compensation paid by similar organizations for functionally comparable positions.”
“The society's bylaws and conflict of interest policy are available for review upon request. The complete audited financial statements are incorporated in the society's annual report, which is available on the boston athenaeum's website: http://www.bostonathenaeum.org. The form 990 and audited financial statements are also available via the massachusetts attorney general's website.”
“The athenaeum accounts for the effect of any uncertain tax positions based on a "more likely than not" threshold to the recognition of the tax positions being sustained based on the technical merits of the position under scrutiny by the applicable taxing authority. If a tax position or positions are deemed to result in uncertainties of those positions, the unrecognized tax benefit is estimated based on a "cumulative probability assessment" that aggregates the estimated tax liability for all uncertain tax positions. The athenaeum has identified its tax status as a tax-exempt entity and its determination of which activities are related and unrelated as its only significant tax positions; however, the athenaeum has determined that such tax positions do not result in an uncertainty requiring recognition. The athenaeum is not currently under examination by any taxing jurisdiction. The athenaeum's federal and state tax returns are generally open for examination for three years following the date filed.”
