Question juridique clé
Whether the taxpayer could claim additional inventory write-downs beyond the privileged one-third reserve for jewelry stock.
Solution extraite
No additional write-down was proven to be commercially justified; the inventory could be valued at cost minus the customary privileged reserve only.
Motifs extraits
The court held that both progressive and retrograde inventory valuation methods are accepted, but a retrograde method requires deduction of the average gross profit margin, not a flat correction. Jewelry and watch items were treated as luxury goods with durable character, not short-lived fashion items. The taxpayer failed to prove specific value losses or the necessity of a larger write-down, and the alleged write-down was based on a blanket assumption for the whole stock.
