Depreciation expense from continuing operations was $16.2, $14.1, and $14.9 million for the years ended December 31, 2011, 2010 and 2009, respectively. Depreciation is calculated principally on the straight-line method over the estimated useful lives of the assets.

Various properties we own that are not used for operations are classified as other assets with a total carrying value of $0.9 million and $0.9 million as of December 31, 2011 and 2010, respectively.

In 2011, a $0.9 million impairment charge was recorded associated with land held for sale included in property, plant and equipment, net, on the Consolidated Balance Sheet and a $3.0 million impairment charge was recorded in 2010 associated with a real estate asset.

As of December 31, 2011 and 2010, we had remaining deferred gains of $1.6 and $2.0 million, respectively, related to sale-leaseback transactions. These deferred gains were being amortized straight-line over the terms of the related leases.
