“The president, treasurer and board of directors review the form 990 before it is filed.”
“The organization follows the policies of its affiliate, american anti-vivisection society (aavs), with which it shares its board of directors. The board of directors monitors and enforces compliance with the conflict of interest policies (as determined by aavs). Annual disclosure forms are collected from each board member and reviewed by the president who ensures that members recuse themselves from voting on any matters in which they may have a dual interest. The board of directors, excluding the president, ensures that the president recuses herself in case of a potential conflict of interest. The conflict of interest policy explicitly deems family and business relationships to have potential for conflicts and requests detailed information on any such relationships as part of the annual conflict of interest policy process.”
“The organization's compensation policies are dictated by its affiliate, american anti-vivisection society (aavs) with whom it shares a board of directors. The board of directors determines compensation of the president by comparing with compensation of equivalent positions using publicly available data. Note the president's salary is determined by aavs but is reported on both returns. Decisions are recorded in board minutes and materials.”
“Governing documents, the conflict of interest policy, and financial statements are available upon request.”
“Salaries reflected on the statement of functional expenses include allocations of salaries as a portion of management expenses that the organization pays to its affilate, the american anti-vivisection society. Note that the one employee, sue leary, is paid by a common paymaster. The organization's affiliate american anti-vivisection society. There is no w-3 reported for this entity; all filing requirements are met through the affiliate as mentioned.”

“Unrealized loss on beneficial interest in perpetual trust 14,757.”
“There was no change in the audit oversight process from the prior year.”
“The organization's quasi-endowment funds fund the various activities of ardf. This includes funding research projects that develop non-animal alternatives to traditional animal experiments and sponsorship of scientific meetings promoting alternatives.”
“Management believes that it has appropriate support for any tax provisions taken, and as such, the foundation does not have any uncertian tax positions that are material to the financial statements.”
“Unrealized gain on beneficial interest in perpetual trust 14,757. Investment fees -142,930.”
