Fidelity monitors the “Expected Yield” (found on the New Issues Auction Results page on Fidelity.com) for each Bill or Note to be auctioned prior to its auction date. Bills or Notes identified as a Reinvestment Position must display a positive Expected Yield during the Open Order period at 8 a.m. ET in order for the Auto Roll Service to trigger a new order. If the Expected Yield is less than 0% each morning at 8 a.m. ET during the Open Order period, Fidelity will not process the Reinvestment Position generated by the Auto Roll Service. As a result, funds that would have otherwise been used to purchase the Reinvestment Position will remain in your core account. Should this occur, you will be notified through the Alert Service shortly after 8 a.m. ET on the day of the auction, so you have time to place a new order for the Treasury Auction should you choose to.
