Discrepancy in Historical Financial Data Coverage

[Shibka]

Greetings,

I have a question regarding a discrepancy in historical financial data. I’m using two different methods to retrieve data:

Method one (we discussed in "Can't retrieve financials prior to 2017"):
`c = Company("ADP")

filings = c.latest("10-K", 16)
xbrls = XBRLS.from_filings(filings)
xbrls.statements

cash = xbrls.statements.cashflow_statement(max_periods=16)
income = xbrls.statements.income_statement(max_periods=16)
balance = xbrls.statements.balance_sheet(max_periods=16)
`

Method two:
`company = Company("ADP")

Get all 10-K filings

filings = list(company.get_filings(form="10-K"))

Storage

all_income, all_balance, all_cash = [], [], []

Process filings

for filing in filings:
try:
obj = filing.obj()
year = getattr(obj, "metadata", {}).get("fiscal_year", filing.filing_date.year)

    if hasattr(obj, "income_statement") and obj.income_statement:
        df = obj.income_statement.to_dataframe()
        df["fiscal_year"] = year
        all_income.append(df)

    if hasattr(obj, "balance_sheet") and obj.balance_sheet:
        df = obj.balance_sheet.to_dataframe()
        df["fiscal_year"] = year
        all_balance.append(df)

    if hasattr(obj, "cashflow_statement") and obj.cashflow_statement:
        df = obj.cashflow_statement.to_dataframe()
        df["fiscal_year"] = year
        all_cash.append(df)

    print(f"✅ Parsed {year}")
except Exception as e:
    print(f"⚠️ Skipped {filing.filing_date}: {e}")`

When I use the first method (e.g., for ADP), I receive all the necessary data—balance sheet, income statement, and cash flow statement—but only for the period from 2018 to 2024.

However, when I use the second method, I’m able to access balance sheet and income statement data from 2011 to 2024, but the cash flow statement data is missing.

Could you please clarify what might be causing this issue?

Thank you in advance.
