We expect an overall modest sales increase in 2015 from global market conditions.  We expect the North America economic  climate will continue to be strong, contributing to stable or modest improvements in the markets we serve.Although the rate of  growth in the Asia Pacific region has slowed, we expect overall economic improvement in that region in 2015.  The economy in  Europe is expected to improve modestly, while the South America countries where we do business are expected to remain  relatively weak in 2015. Adverse developments in the economic conditions of these markets could reduce demand for new  vehicles, causing our customers to reduce their vehicle production and, as a result, demand for our products would be adversely  affected. Adverse global economic conditions could also cause our customers and suppliers to experience severe economic  constraints in the future, including bankruptcy , which could have a material adverse impact on our financial position and results  of operations. We could be adversely impacted by the loss of any of our significant customers, changes in their requirements for our products  or changes in their financial condition. We are reliant upon sales to several significant customers. Sales to our ten lar gest customers accounted for 55% of our  overall sales in 2014. Changes in our business relationships with any of our lar ge customers or in the timing, size and  continuation of their various programs could have a material adverse impact on us. The loss of any of these customers, the loss of business with respect to one or more of their vehicle models on which we  have high component content, or a significant decline in the production levels of such vehicles would negatively impact our  business, results of operations and financial condition. Pricing pressure from our customers also poses certain risks. Inability on  our part to offset pricing concessions with cost reductions would adversely af fect our profitability . We are continually bidding  on new business with these customers, as well as seeking to diversify our customer base, but there is no assurance that our  efforts will be successful. Further , to the extent that the financial condition of our lar gest customers deteriorates, including  possible bankruptcies, mergers or liquidations, or their sales otherwise decline, our financial position and results of operations  could be adversely affected. We may be adversely impacted by changes in international legislative and political conditions. We operate in 25 countries around the world and we depend on significant foreign suppliers and customers. Further , we  have several growth initiatives that are tar geting emerging markets like China and India. Legislative and political activities  within the countries where we conduct business, particularly in emer ging markets and less developed countries, could adversely  impact our ability to operate in those countries. The political situation in a number of countries in which we operate could  create instability in our contractual relationships with no ef fective legal safeguards for resolution of these issues, or potentially  result in the seizure of our assets. Through January 23, 2015, we operated in Venezuela where government exchange controls  and policies placed restrictions on our ability to operate ef fectively and repatriate funds. Our risk associated with operating in  this country was significantly reduced with the divestiture of our operations in  Venezuela on January 23, 2015. However, we  expect to continue exporting product to Venezuela, and our ability to do so effectively could be adversely impacted by  Venezuela government policies. We operate in Argentina, where trade-related initiatives and other government restrictions  limit our ability to optimize operating ef fectiveness. At December 31, 2014, our net asset exposure related to  Argentina was  approximately $30, including $12 of net fixed assets. We may be adversely impacted by the strength of the U.S. dollar relative to the currencies in the other countries in which we do  business. Approximately 58% of our sales in 2014 were from operations located in countries other than the U.S. Currency variations  can have an impact on our results (expressed in U.S. dollars). Currency variations can also adversely af fect margins on sales of  our products in countries outside of the U.S. and mar gins on sales of products that include components obtained from af filiates  or other suppliers located outside of the U.S. Strengthening of the U.S. dollar against the euro and currencies of other countries  in which we have operations could adversely af fect our results reported in U.S. dollars.  We use a combination of natural  hedging techniques and financial derivatives to mitigate foreign currency exchange rate risks. Such hedging activities may be  ineffective or may not of fset more than a portion of the adverse financial impact resulting from currency variations. 6
