Why can IFRS reverse inventory write-downs but US GAAP cannot?

The divergence reflects different philosophies about conservatism. US GAAP (ASC 330) treats a write-down as a new cost basis — once kayaks are carved down to $550, that becomes their accounting reality, and any later recovery is recognized only when sold (boosting gross margin at sale). IFRS (IAS 2) treats the write-down as a temporary valuation allowance; if the impairment condition reverses, you reverse it up to the original cost ceiling ($800, not beyond).

For Zenith Outdoor Gear: IFRS reverses $170 ($720 - $550) through COGS reduction, so current-quarter gross margin gets the boost. US GAAP keeps the $550 basis; when sold at $720, the $170 flows through as realized profit at sale date. Same economic outcome, different timing.

Analyst implications:
- Compare margins carefully across IFRS vs GAAP retailers
- IFRS reversal can be an earnings-management flag — check if NRV recovery is genuine or opportunistic
- Never reverse above original cost under either standard
- LIFO-using firms (US only) cannot apply IFRS anyway, so this question mostly arises for FIFO/WAC firms

The reversal triggers a current-period earnings boost under IFRS that GAAP defers until sale, creating comparability issues for cross-border equity valuation models.
