Roll Forward of Permit
The following table summarizes changes in the carrying amount of permits. No permit exists at our Services Segment. The Company currently has only one definite-lived permit, which is at our DSSI facility. This permit of approximately $545,000 was capitalized in 2009 in connection with the authorization issued by the U.S. EPA to our DSSI facility to commercially store and dispose of radioactive PCBs. This permit is being amortized over a ten year period in accordance with its estimated useful life.
