Once an offering has been allocated, the securities are placed in your account. You can check your account history or positions on Fidelity.com to see if you received an allocation of securities. When you submitted an order, a notification was sent via email that you registered when you signed up for Fidelity Alerts.
Once securities are allocated, you receive a written confirmation. For new issue municipal offerings, the official statement (OS) is available on MSRB's Electronic Municipal Market Access (EMMA) website at https://emma.msrb.org/. The OS contains the same type of information included in the preliminary document, along with amendments such as the exact size of the offering, the net proceeds going to the issuer, and the concession being given to the underwriter.
