* generally , average realized price per metric ton of aluminum includes two elements : a ) the price of metal ( the underlying base metal component plus a regional premium 2013 see the footnote to the table in primary metals above for a description of these two components ) , and b ) the conversion price , which represents the incremental price over the metal price component that is associated with converting primary aluminum into sheet and plate . in this circumstance , the metal price component is a pass- through to this segment 2019s customers with limited exception ( e.g. , fixed-priced contracts , certain regional premiums ) . this segment represents alcoa 2019s midstream operations and produces aluminum sheet and plate for a variety of end markets . approximately one-half of the third-party shipments in this segment consist of sheet sold directly to customers in the packaging end market for the production of aluminum cans ( beverage , food , and pet food ) . seasonal increases in can sheet sales are generally experienced in the second and third quarters of the year . this segment also includes sheet and plate sold directly to customers and through distributors related to the aerospace , automotive , commercial transportation , building and construction , and industrial products ( mainly used in the production of machinery and equipment and consumer durables ) end markets . a small portion of this segment also produces aseptic foil for the packaging end market . while the customer base for flat-rolled products is large , a significant amount of sales of sheet and plate is to a relatively small number of customers . in this circumstance , the sales and costs and expenses of this segment are transacted in the local currency of the respective operations , which are mostly the u.s . dollar , the euro , the russian ruble , the brazilian real , and the british pound. .
