CN Advisory Issuance Committee (CNAIC):

The CNAIC is a committee made up of Charity Navigator’s staff and is led by the CN Advisory System manager. The CNAIC meets regularly to review any public domain information about the alleged questionable behavior or operations of a charity (or an alleged charity) that comes to the attention of Charity Navigator.
Based on the information available, the CNAIC decides whether or not to issue on a CN Advisory on a given charity. For more information please see How We Decide to Post a CN Advisory.
