Part VI, Section B, Line 12c- Conflict of Interest PolicyThe Keystone Foundation monitors and enforces its conflict-of-interest policy by requiring annual disclosure forms from board members and key participants, maintaining these records, and having the CEO, as conflicts administrator, review disclosures in consultation with the board chair and legal counsel. When conflicts are identified, appropriate actions such as disclosure to the board, recusal from decisions, or other measures are implemented.
Part VI, Section B, Line 11b- procedures to review Form 990Both the president and assistant treasurer review a draft of the Form 990 and make the necessary revisions.
