Leasehold Improvements And Deferred Rent [Text Block]	(10) LEASEHOLD IMPROVEMENTS AND DEFERRED RENT We record tenant improvements made to our leased facilities based on the amount of the total cost to construct the improvements regardless of whether a portion of that cost was paid through an allowance provided by the facility's landlord. The amount of the allowance, if any, is recorded as deferred rent. We amortize deferred rent on a straight-line basis over the lease term and record the amortization as a reduction of rent expense.
