“A copy of the form 990 is emailed to the officers for their review prior to its finalization. The final copy of the form 990 is sent to the officer responsible for signing and filing the form 990. He reviews the form prior to signing and filing it.”
“The organization's conflict of interest policy is monitored through the day-to-day communication between the governing body and the headquarter secretariat (located in colloquium, brussels). If a conflict of interest arose, the bylaws (section 9 - resignation and removal) state that "whenever, in the judgement of the board of directors, the best interests of the isrs will be served, any member may be removed from office by two-thirds vote of the members of the board of directors in office, at any meeting of the board of directors duly called and at which a quorum is present."”
“The organization does not compensate its officers or directors, nor does it have any employees. It has contracted with an independent outside organization to provide administration and financial services.”
“The isrs makes its form 990 available upon request.”
“The isrs makes its governing documents, conflict of interest policy, and financial statements available upon request. The isrs' bylaws are on the organization's website.”
