The countdown is based on server time, which is currently:
Beginning January 3, 2011, applicants can dispose of obsolete equipment for payment or other consideration, but no sooner than five years after the equipment is installed.
In general, eligible products and services purchased with Schools and Libraries Program discounts cannot be sold, resold, or transferred for money or any other thing of value (47 C.F.R. Section 54.513(a)).
However, applicants can now dispose of equipment five years or more after installation, even if payment or other consideration is received. Resale or disposal is prohibited before five years have passed.
Note that applicants are not required to continue using the equipment for five years, nor are they required to dispose of equipment five years after installation.
Equipment purchased with Schools and Libraries Program discounts can also be traded in, but no sooner than five years after the equipment is installed. Trade-ins are not allowed before this five-year period has elapsed.
The value of a trade-in does not have to be deducted from the pre-discount amount of a new funding request. Applicants are not required to notify USAC of the disposal or trade-in of equipment. However, an applicant disposing of or trading in equipment should make an appropriate entry in its asset register or inventory.
