We depreciate the cost of property, plant, and equipment by the straight-line method and primarily over the following useful lives:


Land improvements			5 - 30 years
Buildings			10 - 50 years
Machinery and equipment			3- 15 years

At both December 31, 2011 and December 31, 2010, assets held for lease and included in the table above, include $3 million of land, $2 million of land improvements, $66 million of buildings, and $38 million of machinery and equipment. Accumulated depreciation on these assets was $8 million at December 31, 2011 and $4 million at December 31, 2010. All of these assets represent the assets of Foundry Park I.

Interest capitalized was $500 thousand in 2011, $400 thousand in 2010, and $2.0 million in 2009. Of the total amount capitalized in 2009, $1.5 million related to the construction of the office building by Foundry Park I. Capitalized interest is amortized generally over the same lives as the asset to which it relates. Depreciation expense was $33 million in 2011, $29 million in 2010, and $23 million in 2009. Amortization of capitalized interest, which is included in depreciation expense, was $300 thousand in 2011, as well as 2010, and $200 thousand in 2009.
