Postretirement benefit cost components are reclassified in their entirety from accumulated other comprehensive loss to net periodic benefit cost.  Net periodic benefit costs are reported in net income as “Cost of sales” or “Selling, general and administrative expenses” in a manner consistent with the classification of direct labor and personnel costs of the eligible employees.
