As per SA 560, when after the date of the auditor's report but before the date the financial statements are issued, a fact becomes known to the…

"Date the financial statements are issued" reflects the date on which the auditor's report and audited financial statements are made available to the third parties. The date the financial statements are issued generally depends on the regulatory environment of the entity. In some circumstances, the date the financial statements are issued may be the date that they are filed with a regulatory authority. Since audited financial statements cannot be issued without an auditor's report, the date that the audited financial statements are issued must not only be at or later than the date of the auditor's report but must also be at or later than the date the auditor's report is provided to the entity. Therefore, "date the financial statements are issued" can be later than date of providing auditor's report to the entity. OR Standard on Quality Control 1 (SQC 1),“Quality Control for Firms that Perform Audits and Reviews of Historical Financial Information, and Other Assurance and Related Services Engagements”, provides that, unless otherwise specified by law or regulation, audit documentation is the property of the auditor. Therefore, it is not mandatory for CA N to share audit file with client. He may at his discretion, make portions of, or extracts from, audit documentation available to clients, provided such disclosure does not undermine the validity of the work performed, or, in the case of assurance engagements, the independence of the auditor or of his personnel.
