Total capital expenditures for property, plant and equipment and intangible assets (excluding intangibles acquired through business combinations) amounted to $1,026 million, $1,106 million and $1,293 million in 2014, 2013 and 2012, respectively. In 2014 and 2013, capital expenditures were 21 percent and 16 percent lower, respectively, than depreciation and amortization while in 2012 capital expenditures exceeded total depreciation and amortization expenses. This change, commencing in 2013, is due partly to a reduction in capital expenditures but also due to an increase in depreciation and amortization (including amortization of intangible assets acquired in acquisitions).
Capital expenditures in 2014 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 2014 were driven primarily by upgrades and maintenance of existing production facilities, mainly in Sweden, the U.S., Germany and Switzerland. Capital expenditures in emerging markets were lower in 2014 compared to 2013, with expenditures being highest in China, Saudi Arabia, the Czech Republic and Poland. Capital expenditures in emerging markets were made primarily 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 2014, 2013 and 2012 was 29 percent, 33 percent and 31 percent, respectively.
At December 31, 2014, construction in progress for property, plant and equipment was $653 million, mainly in Sweden, the U.S., Switzerland, Saudi Arabia and China, while 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 U.S., Switzerland, Germany and Brazil.
Our capital expenditures relate primarily to property, plant and equipment. For 2015, we estimate the expenditures for property, plant and equipment will be higher than our annual depreciation charge.
