To the extent possible, Caterpillar includes acquisitions in its retail statistics about one calendar year after an acquisition closes in order to have a prior period comparison. In August 2010, Caterpillar acquired Electro-Motive Diesel ("EMD"). Therefore, beginning with January 2012 statistics, EMD's sales of engines and locomotives were included in the "Transportation" sector. The Transportation sector includes power systems for marine, rail and on-highway applications and locomotives.
