In addition, it includes indices on customer Inventories, Prices paid for company inputs, the Reserve of uncompleted orders, and new Orders for export. These indices are derived from information collected electronically from the largest manufacturing companies in Puerto Rico. The estimate is based on a dissemination index methodology, similar to that used in other countries and other states of the United States for similar indices. This Survey is the result of a collaboration with the Puerto Rico Industrial Association.
