Part 1: Functional Currency Determination

ASC 830-10-45 (US GAAP) and IAS 21.9–21.14 (IFRS)

The functional currency is the currency of the primary economic environment in which an entity operates. Determination uses a hierarchy of indicators:

Primary indicators (IAS 21.9 / ASC 830-10-45-2):

| Indicator | Question | |---|---| | Sales price currency | In which currency are sales prices denominated and settled? | | Sales market currency | Which currency dominates the competitive environment in which the entity sells? | | Labor and material cost currency | In which currency are the entity's principal costs (labor, materials) denominated and settled? |

Secondary indicators (IAS 21.10 / ASC 830-10-45-4):

| Indicator | Question | |---|---| | Financing currency | In which currency are debt instruments denominated and settled? | | Cash flow currency | In which currency are receipts from operating activities usually retained? |

Group entity indicators (IAS 21.11):

• Is the foreign operation an extension of the parent's activities (parent's currency indicators dominate)?
• Or does it operate with significant autonomy (local currency indicators dominate)?

Conflict resolution:

• When primary and secondary indicators conflict, judgment is required.
• IAS 21.12 provides that management uses judgment to determine the currency that most faithfully represents the economic effects of transactions, events, and conditions.
• ASC 830-10-45-6: when indicators conflict, management considers the totality of the facts.

Functional currency once determined:

• IAS 21.13: once determined, the functional currency does not change unless there is a change in the underlying transactions, events, and conditions.
• ASC 830-10-45-7: change in functional currency is treated prospectively from the date of the change.

Part 2: Translation Method vs. Remeasurement Method

The Two-Step Framework

Step 1 — Is the entity's record-keeping currency the same as its functional currency?

• No → Apply remeasurement (temporal method) to convert records into functional currency first.
• Yes → Proceed to Step 2.

Step 2 — Is the functional currency the same as the parent's presentation currency?

• No → Apply translation (current rate method) to convert functional currency statements into presentation currency.
• Yes → No translation required.

---

Remeasurement (Temporal Method)

When it applies: foreign currency records ≠ functional currency (entity keeps books in a currency that is not its functional currency).

Rate assignment — ASC 830-10-45-17 / IAS 21.23–21.24:

| Item Category | Rate | |---|---| | Monetary assets (cash, receivables, payables, debt) | Closing rate (balance sheet date) | | Non-monetary assets carried at historical cost (inventory at cost, PP&E, goodwill, intangibles) | Historical rate (rate at date of transaction) | | Non-monetary assets carried at fair value (investment properties at FV, equity securities at FV) | Rate at date of fair value measurement | | Income statement items related to non-monetary items (COGS, depreciation, amortization) | Historical rate (matching the underlying asset) | | Other income statement items (revenue, operating expenses not linked to non-monetary items) | Average rate for the period (or transaction date rate if more appropriate) |

P&L impact: remeasurement gains and losses go to P&L (not OCI).

• ASC 830-20-35-1: transaction gains and losses on monetary items → P&L.
• IAS 21.28: exchange differences on monetary items → P&L in the period.

---

Translation (Current Rate Method)

When it applies: functional currency ≠ presentation currency (entity translates its functional-currency statements into the parent's presentation currency).

Rate assignment — ASC 830-30-45-3 / IAS 21.39–21.42:

| Item Category | Rate | |---|---| | Assets (all) | Closing rate (balance sheet date) | | Liabilities (all) | Closing rate (balance sheet date) | | Income statement items (revenue, expenses, gains, losses) | Average rate for the period (or transaction date rate if exchange rates fluctuate significantly) | | Equity components (share capital, additional paid-in capital, retained earnings at time of investment) | Historical rate (rate at date of investment or transaction) | | Dividends declared | Rate at declaration date |

OCI routing: the net translation difference is the Cumulative Translation Adjustment (CTA):

• ASC 830-30-45-12: CTA → accumulated in OCI (AOCI); not reclassified to P&L until disposal of the foreign operation.
• IAS 21.39: translation differences → OCI (Translation Reserve); recycled to P&L on disposal (IAS 21.48).

---

Part 3: CTA Accumulation, Disposal, and Recycling

Accumulation in OCI

CTA accumulates in OCI for each period that:

• The foreign operation exists with a functional currency different from the parent's presentation currency.
• Exchange rates differ between the opening and closing balance sheet dates.

Disposal — CTA Recycling

IFRS (IAS 21.48):

• On disposal of a foreign operation, the cumulative CTA related to that operation is reclassified from OCI to P&L (recycled) as a reclassification adjustment.
• IAS 21.48C: on partial disposal of a subsidiary that includes a foreign operation, the entity reclassifies a proportionate share of the CTA to the non-controlling interest.

US GAAP (ASC 830-30-40-1):

• On sale or liquidation of a foreign operation, the pro-rata portion of the CTA related to that operation is released from AOCI and recognized in P&L.
• Key difference from IFRS: under US GAAP, partial disposal of a subsidiary does not trigger partial CTA reclassification unless the subsidiary is deconsolidated. ASC 830-30-40 requires full deconsolidation or sale to trigger release.

Long-Term Monetary Intragroup Items (IAS 21.32)

IAS 21.32: exchange differences on monetary items that form part of a net investment in a foreign operation (i.e., long-term intragroup loans with no scheduled repayment) → OCI (not P&L) at the consolidated level.

• At the individual entity level, these may be recognized in P&L.
• The OCI election applies only in consolidated financial statements.

US GAAP equivalent (ASC 830-20-35-3): long-term intercompany transactions that are of an investment nature → CTA in OCI at the consolidated level (same result, different articulation).

---

Part 4: Highly Inflationary Economies

ASC 830-10-45-11 (US GAAP)

Trigger: cumulative three-year inflation rate > 100%.

Consequence: the foreign entity's functional currency is replaced by the parent's reporting currency (USD for a US parent) for accounting purposes. The entity must then remeasure using the temporal method with USD as the functional currency.

Practical implication: non-monetary items (PP&E, inventory) retain their historical USD cost basis; no translation adjustment in OCI — all differences go to P&L.

Affected jurisdictions (as of 2025–2026):

• Argentina: designated highly inflationary for US GAAP purposes; also IAS 29 hyperinflationary.
• Turkey: designated highly inflationary for US GAAP purposes; IAS 29 applied from 1 January 2022.
• Monitor: Ethiopia, Haiti, Iran, Lebanon, South Sudan, Sudan, Venezuela, Yemen, Zimbabwe — verify current status against published indices.

IAS 29 (IFRS) — Hyperinflationary Economies

Trigger: IAS 29.3 indicators include cumulative inflation rate over three years approaching or exceeding 100%, but judgment is required across qualitative indicators including:

• General population preferring to keep wealth in non-monetary assets or relatively stable currencies.
• Monetary amounts stated in terms of a relatively stable foreign currency.
• Interest, wages, and prices linked to a price index.
• Three-year cumulative inflation approaching or exceeding 100%.

Consequence: financial statements (including comparatives) are restated to the measuring unit current at the balance sheet date using a general price index. Non-monetary items are adjusted by applying the change in the general price index from the date of acquisition.

IAS 29.8: all items in the statement of financial position not already expressed in terms of the measuring unit current at the balance sheet date are restated by applying a general price index.

Key difference from ASC 830: IAS 29 restates the financial statements (purchasing power restatement); ASC 830-10-45-11 changes the functional currency designation and applies temporal method remeasurement. These are different mechanical approaches.

Part 5: Net Investment Hedge Accounting

ASC 830-20 / IAS 21.32 and Interaction with ASC 815 / IFRS 9

Net investment in a foreign operation = the reporting entity's interest in the net assets of a foreign operation.

Hedge of net investment:

| Framework | Standard | Hedge gain/loss routing | |---|---|---| | US GAAP | ASC 830-20-35-3 + ASC 815-35-1 | Effective portion → OCI (CTA); reclassified to P&L on disposal of the investment | | IFRS | IAS 21.32 + IFRS 9.6.5.13 | Effective portion → OCI (Translation Reserve); recycled to P&L on disposal |

Eligible hedging instruments:

• Foreign currency-denominated debt instruments (non-derivative hedging instruments).
• Foreign currency forward contracts or cross-currency swaps (derivative hedging instruments).

Designation requirements:

• The hedged item is the net assets of the foreign operation, not individual assets/liabilities.
• Hedge must be formally documented and assessed for effectiveness.

Part 6: Multi-GAAP Comparison Table

| Area | US GAAP (ASC 830) | IFRS (IAS 21) | German HGB | JGAAP (ASBJ No. 22) | CAS 19 (China) | Ind AS 21 | |---|---|---|---|---|---|---| | Translation method | Current rate for all A/L; average for P&L; historical for equity | Same as US GAAP | Closing rate for A/L; historical for equity; average or closing for P&L (simplified) | Broadly similar to IFRS; closing rate for A/L; average for P&L | Similar to IAS 21; closing for A/L; average for P&L | Converged with IAS 21; minor carve-outs | | CTA in OCI | Yes — AOCI; no P&L recycling until disposal | Yes — Translation Reserve; recycled to P&L on disposal | No explicit OCI concept; translation differences generally recognized in equity reserve (§ 308a HGB) | Translation differences → OCI; recycled to P&L on disposal (similar to IFRS) | Translation differences → OCI; recycled on disposal (similar to IAS 21) | Same as IAS 21 — recycled on disposal | | Remeasurement (temporal) gain/loss | P&L | P&L (IAS 21.28) | P&L | P&L | P&L | P&L | | Highly inflationary | Change functional currency to USD (ASC 830-10-45-11) | IAS 29 restatement to current purchasing power | No specific guidance; general prudence principle applies | No specific guidance | Broadly follows IAS 29 concept | Follows IAS 29 | | Long-term intragroup monetary items | OCI at consolidated level (ASC 830-20-35-3) | OCI at consolidated level (IAS 21.32); P&L at entity level | P&L | P&L (no OCI election available) | Similar to IAS 21 | Same as IAS 21 | | CTA recycling on partial disposal of subsidiary | Only on full deconsolidation (ASC 830-30-40) | Proportionate share reclassified (IAS 21.48C) | N/A | Similar to IFRS | Similar to IAS 21 | Same as IAS 21 |

Part 7: Jurisdictional FX Control Overlays

China — SAFE (State Administration of Foreign Exchange)

Relevant to FX translation accounting:

• FX conversion and repatriation of profits from Chinese subsidiaries require SAFE approval; timing of approval affects which exchange rate is used in translation.
• Intercompany loans (cross-border): SAFE registration required; loan principal and interest repatriation subject to SAFE approval and registration — affects the characterization of the loan (short-term trade payable vs. long-term investment-nature loan under IAS 21.32).
• Capital account transactions: foreign direct investment receipts and equity capital repatriation require SAFE approval; timing impacts the historical rate used for equity layer.
• Source: SAFE Regulations on Foreign Exchange Administration — https://www.safe.gov.cn/en/

India — FEMA (Foreign Exchange Management Act) and RBI

Relevant to FX translation accounting:

• Capital account transactions (equity investment, external commercial borrowings — ECB): require RBI approval or registration under FEMA 1999.
• ECB regulations: Indian entities borrowing from foreign parents must comply with RBI ECB Master Direction; the drawn-down currency affects functional currency indicators.
• Repatriation of dividends: permissible subject to compliance with Companies Act and FEMA; timing affects average rate vs. declaration-date rate application.
• Compounding: FEMA violations may result in compounding proceedings — advisors should flag FEMA compliance when advising on FX-denominated intragroup structures.
• Source: RBI Master Directions on External Commercial Borrowings — https://www.rbi.org.in/Scripts/BS_ViewMasDirections.aspx

Brazil — IOF and SPED

IOF (Imposto sobre Operações Financeiras — Tax on Financial Transactions):

• IOF applies to FX conversion transactions (IOF/Câmbio); current rate varies by transaction type (capital inflows, loans, equity).
• IOF on cross-border loans affects the effective interest cost, which may affect functional currency indicators (financing cost currency).
• Source: Receita Federal — https://www.gov.br/receitafederal/en/subjects/taxes/iof

SPED (Sistema Público de Escrituração Digital):

• Brazilian entities must maintain accounting records in BRL and file SPED (ECD — Electronic Accounting Bookkeeping) in BRL regardless of group reporting currency.
• If a Brazilian subsidiary's functional currency is USD (e.g., due to USD-denominated operations), the entity still maintains statutory BRL books and remeasures to USD for group consolidation — a two-step process.
