- **Required Data Fields**:
- fiscalPeriod (e.g. "FY2025", "Q3 2025")
- currency (e.g. "USD", "INR")
- units (e.g. "thousands", "millions")
- totalRevenue
- costOfRevenue
- grossProfit
- researchAndDevelopmentExpense
- sellingGeneralAdministrativeExpense
- operatingIncome
- netIncome
- earningsPerShareBasic
- earningsPerShareDiluted
- **Policy for Missing or Not Reported Line Items**: Set value to null with an explanation in _audit.missingFields

### Raw Financial Text / Table
```text
CONSOLIDATED STATEMENTS OF OPERATIONS (In millions, except share amounts)
Three Months Ended September 30, 2025:
Total net sales: $94,930
Cost of sales: $51,120
Gross margin: $43,810
Operating expenses:
  Research and development: $7,760
  Selling, general and administrative: $6,540
Total operating expenses: $14,300
Operating income: $29,510
Other income/(expense), net: ($210)
Income before provision for income taxes: $29,300
Provision for income taxes: $4,650
Net income: $24,650
Diluted earnings per share: $1.64
```

### Extraction Rules & Constraints
1. **Strict JSON Output Only**:
   - Output valid JSON only, without conversational preamble or markdown postscripts.
2. **Numerical Accuracy**:
   - Extract numerical figures as standard numbers (not strings). Preserve exact currency units (e.g. millions vs thousands as specified in the header).
   - If a number is negative (often in parentheses `(1,234)`), represent it as a negative float/integer (`-1234`).
3. **Reconciliation & Audit Verification**:
   - Verify that: `Gross Profit = Total Revenue - Cost of Goods Sold` and `Operating Income = Gross Profit - Total Operating Expenses`.
   - Include an `_audit` metadata object in the JSON documenting any mathematical discrepancies found in the source text.

Workflow Guidance

  • Select the financial statement type (e.g. 10-K, 10-Q, Balance Sheet).
  • Paste the raw text, OCR transcript, or HTML table directly into the raw data field.
  • Copy the output JSON into your automated ingestion pipeline or data analytics notebook.

Representative AI Output

Sample output produced when using frontier AI models with the default parameters:

```json
{
  "company": "Acme Corp",
  "fiscalPeriod": "Three Months Ended September 30, 2025",
  "currency": "USD",
  "units": "millions",
  "data": {
    "totalRevenue": 94930,
    "costOfRevenue": 51120,
    "grossProfit": 43810,
    "researchAndDevelopmentExpense": 7760,
    "sellingGeneralAdministrativeExpense": 6540,
    "totalOperatingExpenses": 14300,
    "operatingIncome": 29510,
    "netIncome": 24650,
    "earningsPerShareDiluted": 1.64
  },
  "_audit": {
    "mathReconciliation": {
      "grossProfitValid": true,
      "operatingIncomeValid": true
    },
    "missingFields": []
  }
}
```

Pro Optimization & Edge-Case Tips

  • Always prompt the model to preserve negative signs when numbers are written inside parentheses like `(210)`.
  • Add an `_audit` key in your requested schema so the model self-checks its arithmetic before returning the final JSON.
  • Pair this prompt with our Document AI tool for direct PDF and image table parsing.
