Answer: Skysong should report $284,600 as it's December 31 inventory.
Firstly, FOB is a term meaning free on board and can be defined as without charge to the purchaser for delivery on board a carrier (originally a ship), at a specified location or point. It is often used in such phrases as FOB destination to specify the point where the title of goods passes from the seller to the buyer.
Skysong should report $284,600 because that's the total sum of the actual inventory. Summation of $235,000 goods at hand, $27,800 of goods purchased from Pelzer Corporation, and $21,800 of goods sold to Alvarez Company gives $284,000.
