## SA 710 — Comparative Information
### Three Core Definitions
#### 1. Comparative Information
- Amounts and disclosures included in the FS
- In respect of one or more prior periods
- In accordance with the Applicable Financial Reporting Framework (AFRF)
#### 2. Corresponding Figures
- Comparative information where prior period amounts/disclosures are included as part of the current period FS
- Intended to be read only in relation to current period figures
- Not presented as complete standalone financial statements
- Are an integral part of the current period FS
#### 3. Comparative Financial Statements
- Prior period information included for comparison
- If audited, the prior period FS are referred to in the auditor's opinion
- The level of information is comparable to the current period FS

### Critical Reporting Difference
| Approach | Auditor's Opinion Covers |
|---|---|
| Corresponding Figures | Current period only |
| Comparative Financial Statements | Each period for which FS are presented |
---
### Audit Procedures for Comparative Information
The auditor must:
1. Agree prior period figures — Verify that comparative info agrees with amounts/disclosures in the prior period FS
2. Check accounting policy consistency — Ensure policies are consistent across periods; if changed, verify proper accounting and disclosure
3. Investigate possible misstatements — If a possible material misstatement in comparative info is discovered during the current period audit, perform additional procedures to determine whether it exists
4. Follow SA 560 — If the auditor also audited prior period FS, apply SA 560 (Subsequent Events) requirements
5. Written Representations (SA 580) — Request WR for all periods referred to in the opinion. Also obtain a specific WR for any prior period item separately disclosed in the current year Statement of P&L

### When the Auditor's Opinion MUST Refer to Corresponding Figures
Normally the opinion on corresponding figures refers only to the current period. However, reference is required in four cases:
#### Case 1: Prior Report Was Modified
| Sub-case | Treatment |
|---|---|
| Matter is resolved and properly accounted for / disclosed | Current period opinion need not refer to the prior modification |
| Matter is unresolved | Auditor shall modify the current period opinion |
#### Case 2: Material Misstatement in Prior Period (Previously Unmodified Opinion)
- Auditor obtains audit evidence that a material misstatement exists in prior period FS on which an unmodified opinion was previously issued
- Auditor checks whether the misstatement has been dealt with under AFRF
- If not dealt with → express a qualified or adverse opinion on current period FS
#### Case 3: Prior Period Audited by a Predecessor Auditor
If permitted by law/regulation to refer to the predecessor's report, include an Other Matter paragraph stating:
- (a) Prior period FS were audited by the predecessor auditor
- (b) Type of opinion expressed (and if modified, the reasons)
- (c) Date of the predecessor's report
#### Case 4: Prior Period FS Were Not Audited
- State in an Other Matter paragraph that the corresponding figures are unaudited
- This does not relieve the auditor of obtaining SAAE that opening balances are free from material misstatements affecting the current period

### Comparative Financial Statements — Additional Rules
(A) Opinion must refer to each period — When comparative FS are presented, the auditor's opinion shall refer to each period for which FS are presented.
(B) Differing opinion from prior year — If the auditor's current opinion on prior period FS differs from the opinion previously expressed, the auditor shall disclose the substantive reasons in an Other Matter paragraph (per SA 706).
(C) Prior period audited by predecessor — Include an OM paragraph (same (a), (b), (c) as Case 3 above). Additionally:
- If a material misstatement exists in prior period FS (previously reported without modification by predecessor), communicate with management/TCWG and request that the predecessor auditor be informed
- If the prior period FS are amended and the predecessor issues a new report on those amended FS → the current auditor reports only on the current period
(D) Prior period not audited — State in an OM paragraph that corresponding figures are unaudited (same rule as Case 4 for corresponding figures).
