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 the Rhode Island facilities. We periodically re-evaluate and adjust the reserve by considering 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. We are no longer actively seeking additional subtenants due to the short time remaining on the lease period. The summary of the changes to our wind-down reserve related to this facility for 2013 and 2012 were as follows:
|  | January 1 to March 31, 2013 |  |  | January 1 to December 31, 2012 |
Accrued wind-down reserve at beginning of period |  | $ | 854,000 |  |  | $ | 1,683,000 |
Less actual expenses recorded against estimated reserve during the period |  |  | (372,000 | ) |  |  | (1,185,000 | )
Additional expense recorded to revise estimated reserve at period-end |  |  | 23,000 |  |  |  | 356,000 |
Revised reserve at period-end |  |  | 505,000 |  |  |  | 854,000 |
Add deferred rent at period-end |  |  | 124,000 |  |  |  | 249,000 |
Total accrued wind-down expenses at period-end, current |  | $ | 629,000 |  |  | $ | 1,103,000 |
