Deterministic consolidation arithmetic over inputs you declare, per the translation method for a foreign subsidiary: translate the declared subsidiary equity at the declared current (closing) rate and at the declared historical rate, take the difference as the cumulative translation adjustment (CTA), and split the translated equity into the parent's share and the minority (non-controlling) interest at the declared ownership percentage. Every equity figure, rate, and percentage here is yours: the page holds no subsidiary register, no rate table, no FX feed, no ledger, and no clock.
All three are declared inputs, never fetched from any rate source. Under the translation method, equity translated at the current rate less equity translated at the historical rate is the cumulative translation adjustment. This page translates only the single equity figure you declare; it does not classify your balances or choose your rates.
The parent's share of translated equity at the declared ownership percentage; the minority (non-controlling) interest is the residual, so the two shares always sum back to translated equity. Ownership must lie strictly between 0 and 100. All computed figures are rounded to 2 decimal places, half-up.
