[1] Eliminations within operating income primarily reflect the change in the elimination of intercompany profit in inventory not-yet-realized. Eliminations in assets reflect the amount of intercompany profit in inventory as of the balance sheet date. Such intercompany profit is to be realized upon shipment of inventory to the external customers of the Security and Healthcare divisions.
