ACCRUED EXPENSES
13. ACCRUED EXPENSES
 
As part of a fiscal 2012 restructuring, we accrued for lease payments at the cease use date for our United Kingdom facility and have considered free rent, sublease rentals and the number of days it would take to restore the space to its original condition prior to our improvements. Based on these matters, we have a $1,000 reserve for lease related costs. Additionally, we accrued $117 
for legal and professional fees and other costs to remove improvements previously made to the facility.
 At September 30, 2018 and September 30, 2017, respectively, we had $1,117 reserved for the liability. The reserve is classified as a current liability on the Consolidated Balance Sheets.
