After the stock custodian reduces unit inventory quantities requiring revaluation to zero (by issuance to an RA) and has performed the “New Day” process, the stock custodian deletes the item numbers from the stamp stock inventory (at the old price).
The RA prepares PS Form 17 for returning stock and enters the value of the stamps and envelopes to be returned to the unit reserve inventory at the new price. Use the “STAMPS (-)” key, creating an entry in AIC 848, Stamp Stock returned.
