Workflow

Step 1: Structural Audit

Model structure checklist:

Area	Check	Pass Criteria
Cover page	Company, date, version	Present and accurate
Assumptions	All key inputs centralized	No hardcoded values in calc
Historicals	All periods populated	3-5 years
Forecast	Explicit forecast period	3-5 years
Valuation	DCF, comps, football field	All methods present
Checks	Sum, balance, cross-ref	All checks green
Documentation	Methodology notes	Clear and complete

Step 2: Formula Audit

Formula checks:

Check	Description	Pass Criteria
No hardcodes	All inputs in assumptions	✓
Consistent formulas	Same formula across periods	✓
No circularity (unless intended)	Circular refs flagged	✓
Error handling	IFERROR used where needed	✓
Named ranges	Key cells named	✓
Sheet references	Cross-sheet refs work	✓
Broken links	No external links or all work	✓

Common hardcodes to find:

Growth rates embedded in formulas
Multiples typed into cells
Shares outstanding hardcoded
Tax rates not in assumptions

Step 3: Historicals Cross-Check

Cross-check against source data:

Line Item	Model	iFind / AkShare / 巨潮	Difference	Explanation
营业收入
营业成本
归母净利润
总资产
净资产
经营现金流

Cross-check tolerance:

Revenue, profit: ±2%
Balance sheet: ±1%
Cash flow: ±3% (timing differences)

Step 4: CAS Compliance Check

CAS-specific checks:

Check	Description
Revenue net of VAT	营业收入 not gross
R&D expensed	Not capitalized (unless criteria met)
Tax calculation	25% / 15% rate applied correctly
Minority interest	Separated from parent equity
Government grants	Correct classification
合同负债	Recognized appropriately
信用减值损失	CAS 22 model applied

Step 5: Balance Sheet Integrity

BS checks:

Check	Formula	Pass
BS balances	Assets = L + E	✓
Cash flow ties	Ending cash = Beginning + Net CF	✓
Debt schedule	Short + Long = Total debt	✓
Share count	Shares × Price = Market cap	✓
Minority interest	Correct % applied	✓

Step 6: Forecast Logic Check

Forecast quality:

Check	Description	Pass
Growth reasonable	Within industry range	✓
Margins stable	No unexplained jumps	✓
Working capital	Trends with revenue	✓
CapEx	Consistent with depreciation	✓
Debt service	Can be serviced from FCF	✓
Dividend	Consistent with policy	✓

Growth rate benchmarks:

Metric	Conservative	Base	Optimistic
Revenue growth	5-10%	10-20%	20-30%
Margin expansion	0 ppts	0-2 ppts	2-5 ppts
Tax rate	25%	25%	15% (if 高新)

Step 7: Valuation Check

Valuation audit:

Method	Check	Pass
DCF	WACC reasonable (6-10%)	✓
DCF	Terminal growth < GDP growth	✓
DCF	FCF positive in base case	✓
Comps	Peer group appropriate	✓
Comps	Multiples reasonable	✓
Football field	Min/median/max consistent	✓

WACC components (China):

Component	Typical Range
Risk-free rate (CGB 10Y)	2.0-3.0%
Equity risk premium	6-8%
Cost of debt	3-6%
Tax rate	25% (15% for 高新)

Step 8: Sensitivity & Scenario Check

Sensitivity audit:

Check	Description
Sensitivity tables	Key variables tested
Scenarios	Base / Bull / Bear
Tornado chart	Key drivers identified
Monte Carlo (if used)	Assumptions reasonable

Step 9: Common A-share Model Errors

Error checklist:

Error	Detection	Fix
收入用含税	VAT not removed	Divide by 1.13
税率错误	Wrong rate applied	Verify 高新 status
单位错误	千元 vs 万元	Standardize
季度加总错误	Q+Q ≠ Annual	Check sum
增长率计算	Wrong base period	Verify formula
少数股东损益	Missing	Add if applicable
折旧年限	Wrong	Check FA notes

Quality Checks

Before completing:

Data Source Mode Switch: Set env var IFIND_DATA_SOURCE_MODE to control data source preference.

ifind-only (strict): Use iFind only, error if unavailable

ifind-fallback (default): iFind preferred, fallback to AkShare

akshare-only: Skip iFind, use AkShare only

wind-only: Wind only, error if unavailable

wind-fallback: Wind first, fallback to iFind → AkShare
