[Excerpt] The submission of this report to the Congress continues a series of annual reports by the U.S. Department of Labor (DOL) on the trade and employment effects of the Andean Trade Preference Act (ATPA). This nineteenth report covers calendar year 2011 and concludes that preferential tariff treatment under the provisions of the original ATPA and its subsequent amendments has neither had an adverse impact on, nor posed a significant threat to, overall levels of U.S. employment.
