15.1 Comparative Financial Statements & Predecessor Auditor Reporting

15.1 Comparative Financial Statements & Predecessor Auditor Reporting

Core Principle: Financial statements are frequently presented on a comparative basis to enhance comparability and enable users to identify financial trends across periods. Under AU-C 700 (Forming an Opinion and Reporting on Financial Statements), an auditor's reporting responsibilities extend to all periods presented when reporting on comparative financial statements. A continuing auditor must update their report across all periods, while engagements involving a change in auditors require strict adherence to predecessor reporting protocols depending on whether the predecessor's report is reissued or omitted.

1. Overview of Comparative Financial Statements (AU-C 700)

Comparative financial statements consist of financial statements of two or more periods presented in adjacent columns for comparison. Financial reporting frameworks like U.S. GAAP generally encourage or require comparative presentations (for example, SEC rules require two balance sheets and three years of income statements, cash flows, and changes in stockholders' equity for public filers).

The Continuing Auditor Concept

A continuing auditor is an independent auditor who has audited the financial statements of the current period and one or more consecutive immediate prior periods.

• Report Scope: The continuing auditor's report applies to each set of financial statements presented.
• Report Date: The updated report is dated no earlier than the date sufficient appropriate evidence is obtained for the most recent audit, because the evaluation of the prior statements is updated through that date.

2. Continuing Auditor Updating Opinions: Required Disclosures

An updated report is not merely a reissuance of the previous report. A continuing auditor updates their report on prior comparative statements by taking into account information acquired during the current audit.

                                                     |
        +--------------------------------------------+--------------------------------------------+
        |                                                                                         |
     OPINION REMAINS UNCHANGED                                                    OPINION CHANGES ON PRIOR PERIOD
  Reiterate prior opinion on prior year;                                     (e.g., Prior GAAP departure cured by restatement)
  Express current opinion on current year.                                   Express updated opinion on prior period;
  (Can express different opinions on each                                    Add Other-Matter paragraph (EOM too if restated)
  period, e.g., Qualified Y1, Unqualified Y2)                                giving the four required disclosures.

When an Opinion on a Prior Period Changes

During the current period audit, the continuing auditor may become aware of circumstances or events that affect the financial statements of a prior period. For example, a prior qualification might have been caused by a departure from GAAP (such as failure to capitalize finance leases or improper inventory valuation). In the current year, the entity retroactively restates the prior period in full accordance with GAAP.

When the continuing auditor updates their report and issues an opinion that differs from the previous opinion, AU-C 700 requires an Other-Matter paragraph with the four disclosures below. If the prior statements were restated to correct a material misstatement, AU-C 708 separately requires an Emphasis-of-Matter paragraph about the restatement.

The Four Required Disclosures for a Changed Opinion

Illustrative Scenario: Prior Qualification Cured by Restatement

• Year 1: Client valued inventory at fair market value (a GAAP departure). The auditor issued a qualified audit report on March 15, Year 2.
• Year 2: On February 20, Year 3, client adopts GAAP lower of cost or net realizable value, retroactively restating the Year 1 financial statements. The restatement is appropriately disclosed in Note 4.
• Auditor Action: The continuing auditor expresses an unmodified opinion on both Year 1 and Year 2. The auditor includes an Other-Matter paragraph stating the date of the previous report (March 15, Year 2), the opinion previously expressed (qualified), the reason for the change (restatement to GAAP, described in Note 4), and that the updated opinion on Year 1 differs from the previous opinion. Because Year 1 was restated to correct a misstatement, the report also includes an Emphasis-of-Matter paragraph referring to Note 4.

3. Predecessor Auditor's Report is Reissued

When a company changes accounting firms, the prior-period financial statements may be presented alongside the current-period statements. One option is for management to request the predecessor auditor to reissue their previous report.

+-------------------------------------------------------------------------------------------------------+
|                               PROCEDURES FOR REISSUING PREDECESSOR AUDIT REPORT                       |
|                                                                                                       |
|   Step 1: Read Current Statements     --> Inspect current period comparative presentation.            |
|   Step 2: Compare Statements          --> Verify prior figures match audited records.                 |
|   Step 3: Successor Rep Letter        --> Inquire if successor found material prior errors.           |
|   Step 4: Management Rep Letter       --> Confirm no unrecorded subsequent events affecting prior.   |
|                                                                                                       |
|   REPORT DATING:                                                                                      |
|   - Standard Reissuance: Retain ORIGINAL report date (assumes no post-issuance responsibility).       |
|   - Restated Prior Period: DUAL DATE (e.g., "March 10, Year 2, except for Note 3, as to which...")   |
+-------------------------------------------------------------------------------------------------------+

Mandatory Predecessor Procedures Before Reissuing

A predecessor auditor is not expected to perform a complete re-audit. However, because their name is being associated with current comparative filings, AU-C 560 requires the predecessor to perform four specific procedures before reissuing:

1. Read the financial statements of the current period.
2. Compare the prior-period statements that were audited with the comparative financial statements to be presented.
3. Obtain a letter of representation from the successor auditor, inquiring whether the successor's audit revealed any matters that might have a material effect on, or require disclosure in, the prior-period financial statements.
4. Obtain a letter of representation from former client management, confirming whether management believes any subsequent events have occurred that require adjustment or disclosure in the prior-period statements.

Report Dating Rules for Reissued Reports

• Unchanged Statements: The reissued report retains the original report date to avoid implying that the predecessor investigated events occurring after that date.
• Restated Prior-Period Statements: If the prior statements were restated due to a subsequent event or error correction, the predecessor auditor must either dual date the report (e.g., "March 15, Year 2, except for Note 6, as to which the date is March 1, Year 3") or use a new, current report date (which requires extending subsequent event procedures to the new date).

4. Predecessor Auditor's Report is NOT Reissued

If the predecessor auditor refuses to reissue their report, or if client management decides not to engage them to do so, the successor auditor must report on the current period while addressing the prior period in the audit report.

+-------------------------------------------------------------------------------------------------------+
|                          SUCCESSOR AUDITOR OTHER-MATTER PARAGRAPH (AU-C 700)                          |
|                                                                                                       |
|   The successor auditor must include an Other-Matter paragraph stating:                              |
|   1. The prior-period financial statements were audited by a predecessor auditor.                     |
|   2. The PREDECESSOR AUDITOR IS NOT NAMED (unless the predecessor's practice was acquired/merged).    |
|   3. The TYPE OF OPINION expressed by the predecessor (and substantive reasons if modified).         |
|   4. The NATURE of any Emphasis-of-Matter or Other-Matter paragraphs in the predecessor's report.     |
|   5. The DATE of the predecessor auditor's report.                                                    |
+-------------------------------------------------------------------------------------------------------+

Successor Handling of Prior Period Restatements

What happens if the prior-period financial statements audited by a predecessor auditor are materially misstated and retroactively restated in the current comparative presentation?

Exam Trap: The successor auditor never names the predecessor auditor in their Other-Matter paragraph. Saying "The Year 1 financial statements were audited by Smith & Jones, CPAs" is an automatic exam distractor. The only narrow exception is when the predecessor's accounting practice was formally acquired by or merged with the successor firm.

5. Prior-Period Statements Reviewed, Compiled, or Unaudited

When current-period financial statements are audited but prior comparative periods were subject to a lower level of service (or no service at all), users must be informed of the lack of audit assurance.

                                                     |
        +--------------------------------------------+--------------------------------------------+
        |                                                                                         |
  PRIOR PERIOD REVIEWED OR COMPILED (SSARS)                                        PRIOR PERIOD UNAUDITED
  Successor adds an Other-Matter paragraph stating:                         Successor adds an Other-Matter paragraph stating:
  - Prior service performed (Review or Compilation)                         - Prior statements were not audited, reviewed, or compiled
  - Date of the prior SSARS report                                          - Auditor assumes no responsibility for them
  - Description of material modifications (if any)                          - Statements should be clearly labeled as "UNAUDITED"
  - Statement that no audit was performed and no audit assurance obtained   - Auditor disclaims an opinion on the prior period

Mandatory Statements in the Other-Matter Paragraph for Prior SSARS Engagements

If prior-period statements were reviewed or compiled under SSARS and presented comparatively with current audited statements:

1. State the service performed (compilation or review) in the prior period.
2. State the date of the prior report.
3. Describe any material modifications noted in that prior report.
4. Explicitly state that the service was less in scope than an audit, did not involve obtaining reasonable assurance, and that the auditor expresses no opinion and assumes no responsibility for the prior period.
