Why translate at all?
Companies file in their functional reporting currency (USD, EUR, TWD, CNY, and so on). Sorting raw revenue in yen next to raw revenue in dollars would not rank economic scale — you need a single presentation currency. Our leaderboards therefore sort on USD columns derived from each filing, while still showing the original reporting currency on listings where it helps context.
IFRS IAS 21 (what we mirror)
IAS 21 — The Effects of Changes in Foreign Exchange Rates is the IFRS standard that governs how foreign-currency amounts are translated when presenting financial information in a currency other than an entity's functional currency. For a plain-English overview of the ideas (functional currency, presentation currency, exchange differences), start with the official IFRS summary page:
IFRS IAS 21 — official IFRS Foundation page
The pattern used by many index providers and data vendors for cross-border comparisons is the current rate method: income-statement and cash-flow flows are translated using exchange rates that relate to the period of those flows (commonly an average rate over the period), while balance-sheet stocks are translated at the rate on the balance-sheet date (the closing rate). U.S. GAAP users will recognize the same economic idea under ASC 830 (Foreign Currency Matters) for translation of foreign operations — we cite IAS 21 here because it is the label most readers expect on an international site, but the rate choices are analogous.
What TickerLeague does in practice
- TTM income and cash-flow metrics — each fiscal quarter is translated from the issuer's reported currency to USD using an average daily FX rate over that quarter's window, then the last four quarters are summed. That keeps each quarter economically consistent before aggregation.
- MRQ balance-sheet metrics — balance-sheet lines for the most recent quarter are translated to USD using the closing rate on (or last trading day on or before) the balance-sheet date.
- FX source — end-of-day FX pairs ingested from our market-data feed (same vendor chain as price history), normalized into a single "foreign currency → USD" view for SQL lookups.
- Missing history — if we do not have exchange rates for a currency over part of a filing window, the translated USD fields for that row may stay empty and the issuer can drop out of that particular leaderboard until coverage exists.
