# Managing Segment Reporting

Structures segment reporting under ASC 280 (IFRS 8 for IFRS reporters) by identifying operating segments through the management approach, applying quantitative thresholds, measuring segment profit/loss and assets, and preparing required disclosures. [VERIFY: Confirm applicable standard — ASC 280 vs. IFRS 8 — based on entity's reporting framework.]

## When To Use

- Preparing annual or interim segment disclosures for SEC filings (10-K, 10-Q) or IFRS financial statements
- Evaluating whether a new business line, acquisition, or reorganization creates or eliminates an operating segment
- Responding to auditor or SEC staff comments questioning segment aggregation or CODM identification
- Allocating shared costs, intersegment revenues, or corporate-level items across segments
- Assessing whether quantitative thresholds trigger a new reportable segment or allow aggregation

## Inputs To Gather

- **Organizational structure**: Entity org chart, internal reporting packages sent to the chief operating decision maker (CODM)
- **CODM identification**: Title, role, and evidence of how resource-allocation and performance-assessment decisions are made [VERIFY: CODM may be an individual or a group under recent ASC 280 amendments]
- **Internal financial reports**: Discrete financial information reviewed by the CODM — revenue, profit/loss measures, assets by component
- **Prior-period segment disclosures**: Last filed segment footnote for consistency and restatement tracking
- **Intersegment pricing data**: Transfer pricing methodology, elimination entries, and any management adjustments
- **Aggregation criteria support**: Economic-characteristics analysis, long-term gross margin trends, and qualitative similarity factors if aggregating segments

## Workflow

1. **Identify the CODM**
   - Determine who allocates resources and assesses performance — may be CEO, COO, executive committee, or board subset
   - Document evidence: meeting agendas, report distribution lists, decision memos

2. **Determine operating segments**
   - List each component that (a) engages in revenue-earning activities, (b) has discrete financial information, and (c) is regularly reviewed by the CODM
   - Exclude corporate-level or shared-services components that do not earn external revenue unless they meet all three criteria

3. **Evaluate aggregation criteria**
   - Two or more operating segments may be aggregated only if they share similar economic characteristics AND are similar across all five qualitative factors: products/services, production processes, customer type/class, distribution methods, and regulatory environment
   - Prepare a quantitative gross-margin convergence analysis over 3–5 years to support "similar economic characteristics" [VERIFY: SEC staff has scrutinized aggregation — ensure documentation is robust]

4. **Apply quantitative thresholds**
   - Test each segment (or aggregated group) against the 10% thresholds: (a) combined revenue (external + intersegment) ≥ 10% of all segments' combined revenue, (b) absolute profit or loss ≥ 10% of the greater of (i) combined profit of all profitable segments or (ii) combined loss of all loss segments, (c) assets ≥ 10% of combined assets
   - Confirm that reportable segments collectively account for ≥ 75% of consolidated external revenue; if not, add segments until the threshold is met

5. **Measure segment amounts**
   - Use the measure reported to the CODM — not necessarily GAAP-basis; reconcile to consolidated totals
   - Identify and consistently apply allocation methods for shared costs, corporate overhead, and intersegment eliminations
   - For each reportable segment, determine which line items (interest revenue, interest expense, depreciation/amortization, significant noncash items, income tax) are included in the CODM's measure

6. **Prepare required disclosures**
   - General information: factors used to identify segments, types of products/services by segment
   - Profit or loss and assets: segment revenue (external and intersegment separately), segment profit/loss measure, segment assets, plus any additional items regularly provided to the CODM [VERIFY: ASC 280 amendments effective for fiscal years beginning after December 15, 2023 expand required disclosures — confirm applicability]
   - Reconciliations: segment totals to consolidated revenue, profit/loss before tax, assets, and every other significant reconciling item with narrative explanation
   - Entity-wide disclosures: revenue by product/service, by geographic area (domestic vs. material foreign countries), and major-customer concentration (≥ 10% of consolidated revenue)

7. **Restatement and consistency**
   - If segments change due to reorganization, restate prior-period segment data to conform to the new structure, unless impracticable
   - Disclose the nature and effect of any change in reportable segments

## Output

- **Segment identification memo**: Documents CODM determination, operating segment listing, aggregation rationale (if applicable), and quantitative threshold analysis
- **Segment disclosure draft**: Formatted footnote text with tables for revenue, profit/loss, assets, and reconciliations — ready for insertion into financial statements
- **Reconciliation schedules**: Detailed bridge from segment totals to consolidated financials, with labeled reconciling items
- **Aggregation support workpaper**: Gross-margin trend analysis and qualitative-factor comparison (when segments are aggregated)

## Quality Checks

- Every operating segment is either reported separately or explicitly aggregated with documented justification — no segments are silently omitted
- Quantitative thresholds are applied to the correct denominators (combined segments, not consolidated totals)
- The 75% external-revenue sufficiency test is met
- Reconciling items between segment totals and consolidated amounts are individually identified and explained — no unexplained "other" buckets exceeding materiality
- Intersegment revenues and related eliminations net to zero in the reconciliation
- Prior-period comparatives are restated if segment composition changed, with disclosure of the change
- All [VERIFY] items are resolved with jurisdiction- and entity-specific confirmations before finalizing
