Joint Cost Allocation-Market Value at Split-off Method Man O'Fort Inc. produces two different styles of door handles, standard and curved. The door handles go through a joint production molding process costing $31,000 per batch and producing 2,400 standard door handles and 1,200 curved door handles at the split-off point. Both door handles undergo additional production processes after the split-off point, but could be sold at that point: the standard style for $6 per door handle and the curved style for $3 per door handle.
