Equipment primarily consists of: (i) manufacturing equipment to produce our KL4 surfactant products, including SURFAXIN and our lyophilized KL4 surfactant for AEROSURF and SURFAXIN LS, for use in our preclinical studies, clinical trials and potential commercial needs; (ii) laboratory equipment for manufacturing, analytical, research and development activities; and (iii) computers and office equipment to support our overall business activities.

Leasehold improvements primarily consist of construction of an analytical and development laboratory in our Warrington, Pennsylvania headquarters, which was completed in 2007.  The activities conducted in our laboratory include release and stability testing of raw materials as well as preclinical, clinical and commercial drug product supply.  We also perform development work with respect to our aerosolized and lyophilized dosage forms of our KL4 surfactant.  In addition, in 2007, we built a microbiology laboratory at our manufacturing facility in Totowa, New Jersey, to support production of our drug product candidates.  The microbiology laboratory will be amortized through the end of the lease term for our Totowa, New Jersey facility in December 2014.
 
Depreciation expense on property and equipment for the years ended December 31, 2012, 2011 and 2010 was $0.9 million, $1.3 million and $1.4 million, respectively.
