Form 990, Part VI, Section A, line 7B

Amendments to Bylaws must first be approved by the Council. Following approval by Council, amendments will be publicized to allow members to discuss the amendment by electronic discussion board for thirty days.

Information for APS' form 990 is compiled by the APS Manager, Financial Systems, Policies and Procedures. The information is used by the Society's tax consultant to prepare a draft of the form, which is reviewed by APS' CFO for accuracy and completeness. The final approved form 990 is submitted to IRS by the tax consultant.

Form 990, Part VI, Section B, line 12C

Each year all APS Board members, officers, and managers are required to complete a disclosure form in which such covered person discloses his or her relationship or affiliation with any person, firm, or entity which proposes to do business, or who is doing business, with APS, and/or who holds a position of influence with another related organization. By signing the statement, the Board member, officer or manager acknowledges that they have received and reviewed the APS Conflict of Interest Policy.

Form 990, Part VI, Section B, line 15A

Annually, the American Physiological Society (APS) engages a third party consultant to perform a study of comparable salaries and wages for like organizations in its geographical area. Findings of the study are used to provide guidance to APS' Council (board of directors), who are responsible for approving annual salary and wage scale increases. The Executive Director's salary is approved by a smaller group of the Council (Executive Committee). In addition, the APS periodically engages a third party consultant to review job descriptions for each position to ensure compensation levels are appropriate for the knowledge and skills required to perform the duties of each position.

Form 990, Part VI, Section C, line 19

The governing documents of the American Physiological Society are available to the public via the APS website. The conflict of interest policy and financial statements are not made available to the public.

IRS990/Desc0American Physiological Society (Society) typically conducts three scientific meetings per year, one annual meeting each spring and two smaller scientific conferences. The spring meeting normally attracts between 3,000 and 4,000 scientists, which represent the target audience directly benefiting from the scientific offerings of the Society. The two smaller conferences normally attract between 125 and 350 scientists who represent the number of persons benefiting directly from the Society's symposia and workshops.The Society publishes 16 scientific journals that serve as the vehicle for the dissemination of the investigator's research. The Society publishes more than 25,000 pages and receives over 5,500 manuscripts for consideration. Each manuscript has an average of three authors, representing a population of over 17,000 scientists who benefit from the society's publications. In addition, there are over 5,000 subscriptions to the 13 journals self-published by the Society. The majority of the subscribers are libraries providing a large target audience for the journals. Not only faculty, but also students and clinicians refer to the Society's journals providing for a potential target audience in excess of 100,000.
