QCNA members can choose the method best suited to their needs. The purpose of ABC is to set standards by which circulation and other data of member publishers may be audited, verify facts and figures through field auditor's examination of all pertinent records, and report these facts and figures through regularly published, standardized reports. Week by week records are maintained in a form similar to accounting records. An accountant acts as a neutral party who verifies to advertising buyers that the circulation claims are honest and reliable. The same applies for VCC auditing.
Circulation is verified annually.
Participants in the VCP program have the option of using their own accountant or the internal auditor of CCNA to sign the report forms. A program of random field audits of internally audited verification is also made. CCAB audits are for either all controlled circulation or any combination of paid and controlled circulation publications.
