[1] During the second quarter of 2015, we completed the sale of our North American foam trays and absorbent pads business. During the first quarter of 2015, the assets and liabilities met the criteria of held for sale classification. Accordingly, we reclassified $42 million of assets and $6 million of liabilities as held for sale as of December 31, 2014. Refer to Note 3, “Divestitures and Acquisitions” of the notes to condensed consolidated financial statements for further details.

For the twelve months ended December 31, 2014, these reclassifications resulted in a decrease in unrecognized pension items of $13.6 million, an increase in unrecognized gains (losses) on derivative instruments for cash flow hedge of $1.0 million, and an increase in the cumulative translation adjustment of $12.6 million. For the twelve months ended December 31, 2013, these reclassifications resulted in an increase in unrecognized pension items of $2.9 million, an increase in unrecognized gains (losses) on derivative instruments for cash flow hedge of $0.4 million, and a decrease in the cumulative translation adjustment of $3.3 million
