Answer:
The company must not make any adjustment entries in year x3 since the FOB means "Free on board" and at the moment the buyer delivers the goods at the port of shipment, at that time the risks of loss or damage of merchandise are transferred to the buyer from the seller
When this happens, the sale is made since the seller no longer owns the merchandise.
n this case, the seller does not own the merchandise since December 28 and has already made the corresponding records. so he should not make any adjustments.
