Wind-Down Expenses [Abstract] |
Wind-Down Expenses | Note 6. Wind-Down Expenses Rhode Island In October 1999, we relocated to California from Rhode Island and established a wind down reserve for the estimated lease payments and operating costs of our scientific and administrative facility in Rhode Island. Even though we intend to dispose of the facility at the earliest possible time, we cannot determine with certainty a fixed date by which such disposal will occur. In light of this uncertainty, we periodically re-evaluate and adjust the reserve. We consider various factors such as our lease payments through to the end of the lease, operating expenses, the current real estate market in Rhode Island, and estimated subtenant income based on actual and projected occupancy. The summary of the changes to our wind-down reserve related to this facility for 2012 and 2011 were as follows:
|  | January 1 to March 31, 2012 |  |  | April 1 to June 30, 2012 |  |  | July 1 to September 30, 2012 |  |  | January 1 to September 30, 2012 |  |  | January 1 to December 31, 2011 |
