9. Impairment of Long-Lived Assets

We evaluate assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We measure the amount of any impairment by comparing the carrying value of the asset to market prices for similar assets. In connection with the amendment of the Company's Tarrytown lease, we recognized impairment losses of $347 on leasehold improvements and machinery and equipment removed from service, and those losses are included in Research and development expenses in our accompanying Consolidated Statements of Operations for the three and six months ended June 30, 2013.
