[1] The change in total assets in 2014 primarily reflects the depreciation of the Russian ruble.

[2] Corporate assets consist principally of cash and cash equivalents, short-term investments, derivative instruments, property, plant and equipment and certain pension and tax assets. In 2014, the change in total Corporate assets was primarily due to the decrease in cash and cash equivalents and certain pension assets, partially offset by an increase in short-term investments.
