34 UNITED TECHNOLOGIES CORPORATION hourly and salaried employees, the exiting of approximately 2 mil- lion net square feet of facilities and the disposal of assets asso- ciated with the exited facilities. As of December 31, 2012, we have completed, with respect to the actions initiated in 2011, net work- force reductions of approximately 4,200 employees and exited 200,000 net square feet of facilities. We are targeting to complete in 2013 the majority of the remaining workforce and all facility related cost reduction actions initiated in 2011. Approximately 75% of the total pre-tax charge will require cash payments, which we have and expect to continue to fund with cash generated from operations. During 2012, we had cash outflows of approximately $153 million related to the 2011 actions. We expect to incur additional restructuring charges of $29 million to complete these actions. We expect recurring pre-tax savings to increase over the two-year period subsequent to initiating the actions to approximately $280 million annually. For additional discussion of restructuring, see Note 13 to the Consolidated Financial Statements. The financial performance of our commercial businesses can be influenced by a number of external factors including fluctuations in residential and commercial construction activity, regulatory changes, interest rates, labor costs, foreign currency exchange rates, customer attrition, raw material and energy costs, credit markets and other global and political factors. UTC Climate, Con- trols & Security’s financial performance can also be influenced by production and utilization of transport equipment, and for its resi- dential business, weather conditions. Geographic and industry diversity across the commercial businesses help to balance the impact of such factors on our consolidated operating results, particularly in the face of uneven economic growth. While Otis faced challenging economic conditions in Europe and lower order rates in China during the first half of the year, improving market conditions in China and North America resulted in higher order rates in the second half of the year. New equipment orders in China declined for the year (3%), but increased during the fourth quarter (19%) as compared with the fourth quarter of 2011. Organic sales for 2012 within each of our commercial businesses were consistent with prior year levels. In 2012, 70% of total commercial business sales were generated outside the U.S., including U.S. export sales, as com- pared to 72% in 2011.
