How do you handle foreign subsidiary translation in a hyperinflationary economy?

Question

Hyperinflationary environments require special treatment because historical cost financial statements become meaningless when the currency is rapidly losing value.

**Definition of Hyperinflation:**
- **IFRS (IAS 29):** Cumulative inflation over three years approaches or exceeds **100%** (roughly 26% compounded annually). IFRS also lists qualitative indicators like prices being stated in a stable foreign currency.
- **US GAAP (ASC 830):** Cumulative inflation over three years of approximately **100%** or more. The guidance is less prescriptive on qualitative factors.

**Treatment Differences:**

| Approach | IFRS | US GAAP |
|---|---|---|
| Step 1 | Restate local currency statements to current purchasing power using a price index | Do NOT restate — use original historical cost |
| Step 2 | Translate all items at the **current rate** | Use the **temporal method** (parent's currency becomes functional) |
| Balance sheet exposure | All amounts at current rate after restatement | Net monetary items only |
| G/L location | OCI (CTA) | Income statement (remeasurement) |

**Example:** Stonebridge Capital has a subsidiary, Aldara Mining, in a South American country experiencing 40% annual inflation (cumulative three-year: ~175%).

**Under IFRS:**
1. Restate Aldara's local currency statements using a general price index
2. Non-monetary items (PP&E, inventory) are restated upward for inflation
3. A purchasing power gain/loss is recognized on net monetary items
4. Then translate all restated amounts at the current exchange rate

**Under US GAAP:**
1. Deem the functional currency to be the parent's reporting currency (USD)
2. Apply the temporal method directly to the unadjusted local currency statements
3. Non-monetary assets at historical rates, monetary items at current rate
4. Remeasurement gain/loss flows through the income statement

**Practical implication:** IFRS produces a 'truer' picture because it adjusts for the loss of purchasing power before translating. US GAAP is simpler but may show outdated non-monetary asset values translated at stale historical rates.
