[The following paragraphs of AS 2805, amended to read as follows, will be effective for audits of fiscal years ending on or after December 15, 2017. See PCAOB Release No. 2017-001. The current standard can be found  here.]

.12     There are circumstances in which an auditor should obtain updating representation letters from management. If a predecessor auditor is requested by a former client to reissue (or consent to the reuse of) his or her report on the financial statements of a prior period, and those financial statements are to be presented on a comparative basis with audited financial statements of a subsequent period, the predecessor auditor should obtain an updating representation letter from the management of the former client.¹⁵Also, when performing subsequent events procedures in connection with filings under the Securities Act of 1933, the auditor should obtain certain written representations.¹⁶ The updating management representation letter should state (a) whether any information has come to management's attention that would cause them to believe that any of the previous representations should be modified, and (b) whether any events have occurred subsequent to the balance-sheet date of the latest financial statements reported on by the auditor that would require adjustment to or disclosure in those financial statements.¹⁷

¹⁵     See paragraph .55 of AS 3105, Departures from Unqualified Opinions and Other Reporting Circumstances.  

¹⁶     See AS 4101.10. 

¹⁷     An illustrative updating management representation letter is contained in appendix C, "Illustrative Updating Management Representation Letter" [paragraph .18]. 

.13     Management's refusal to furnish written representations constitutes a limitation on the scope of the audit sufficient to preclude an unqualified opinion and is ordinarily sufficient to cause an auditor to disclaim an opinion or withdraw from the engagement.¹⁸However, based on the nature of the representations not obtained or the circumstances of the refusal, the auditor may conclude that a qualified opinion is appropriate. Further, the auditor should consider the effects of the refusal on his or her ability to rely on other management representations.

¹⁸     See AS 3105.05–.17.
