In 2015, we reclassified to Asset held for sale real property of our former manufacturing facility in Germany. The value of $5.0 million as of December 31, 2015 reflects the estimated selling price. We anticipate the sale of the property to occur in 2016. Included in the table above for 2014 are $7.7 million in land and land improvements, $7.6 million in buildings, and $6.2 million in related accumulated depreciation, related to that asset.
