37 CFR 262.6 - Verification of statements of account.
(b) Frequency of verification. The Designated Agent may conduct a single audit of a Licensee, upon reasonable notice and during reasonable business hours, during any given calendar year, for any or all of the prior 3 calendar years, but no calendar year shall be subject to audit more than once.
(c) Notice of intent to audit. The Designated Agent must file with the Copyright Office a notice of intent to audit a particular Licensee, which shall, within 30 days of the filing of the notice, publish in the Federal Register a notice announcing such filing. The notification of intent to audit shall be served at the same time on the Licensee to be audited. Any such audit shall be conducted by an independent and qualified auditor identified in the notice, and shall be binding on all parties.
(d) Acquisition and retention of records. The Licensee shall use commercially reasonable efforts to obtain or to provide access to any relevant books and records maintained by third parties for the purpose of the audit and retain such records for a period of not less than 3 years. The Designated Agent shall retain the report of the verification for a period of not less than 3 years.
(e) Acceptable verification procedure. An audit, including underlying paperwork, which was performed in the ordinary course of business according to generally accepted auditing standards by an independent and qualified auditor, shall serve as an acceptable verification procedure for all parties with respect to the information that is within the scope of the audit.
(f) Consultation. Before rendering a written report to the Designated Agent, except where the auditor has a reasonable basis to suspect fraud and disclosure would, in the reasonable opinion of the auditor, prejudice the investigation of such suspected fraud, the auditor shall review the tentative written findings of the audit with the appropriate agent or employee of the Licensee being audited in order to remedy any factual errors and clarify any issues relating to the audit; Provided that the appropriate agent or employee of the Licensee reasonably cooperates with the auditor to remedy promptly any factual errors or clarify any issues raised by the audit.
(g) Costs of the verification procedure. The Designated Agent shall pay the cost of the verification procedure, unless it is finally determined that there was an underpayment of 10% or more, in which case the Licensee shall, in addition to paying the amount of any underpayment, bear the reasonable costs of the verification procedure.
