Total capital expenditures for property, plant and equipment and intangible assets (excluding intangibles acquired through business combinations) amounted to $1,106 million, $1,293 million and $1,021 million in 2013, 2012 and 2011, respectively. In 2013 capital expenditures were 16 percent lower than depreciation and amortization, while in 2012 and 2011, capital expenditures exceeded total depreciation and amortization expenses for the respective year. This change is due partly to a reduction in capital expenditures but also to an increase in amortization expense from intangible assets acquired in business combinations.
Capital expenditures in 2013 remained at a significant level in mature markets, reflecting the geographic distribution of our existing production facilities. Capital expenditures in Europe and North America in 2013 were driven primarily by upgrades and maintenance of existing production facilities, mainly in the United States, Sweden, Switzerland and Germany, as well as new facilities in Sweden and the United States. Capital expenditures in emerging markets were reduced in 2013 compared to 2012, with expenditures, mainly for new facilities, being highest in China, Poland, Brazil and Bulgaria. Capital expenditures in emerging markets were made to increase production capacity by investment in new or expanded facilities. The share of emerging markets capital expenditures as a percentage of total capital expenditures in 2013, 2012 and 2011 was 33 percent, 31 percent and 34 percent, respectively.
At December 31, 2013 and 2012, construction in progress for property, plant and equipment was $645 million and $627 million, respectively, mainly in Sweden, the United States, Switzerland, Germany and Brazil, while at December 31, 2011, it was $548 million, mainly in Sweden, Switzerland, the United States, Brazil and China.
Our capital expenditures relate primarily to property, plant and equipment. For 2014, we plan to increase our capital expenditures and estimate the expenditures for property, plant and equipment will be higher than our annual depreciation charge. We anticipate investments will be higher in the Americas and Asia but will decrease in Europe.
