Shares: connector/market_inputs

Amounts: USD (converted) · As reported
Converted modes use NBK / ECB-linked rates: balance sheet date for BS items, period average for P&L and cash flow (see filing row evidence). As reported keeps each row in its filing currency.

Financial results

Monetary columns are in B IDR, one decimal; scale (K/M/B/T) keeps values readable. For the period (default) shows P&L and cash flow for that row’s reporting window: quarterly amounts when the feed uses quarter-duration facts (typical US 10-Q revenue and income), quarterly cash flows after stripping YTD where only cumulative tags exist, and an implied Q4 on 31 Dec FY rows (P&L: FY minus Q1–Q3; operating / investing cash flow: FY 12m minus 9M YTD to 30 Sep when sourced from SEC builder evidence) so they match 10-Q scale. Some issuers still use cumulative YTD minus the prior row in the same calendar year. As reported shows values stored on each row (e.g. full-year on FY). Balance sheet is always as reported. Source JSON may use millions etc.; conversion uses amounts_unit per row.
