This Preliminary Term Sheet has been prepared solely for informational purposes and is not an offer to buy or sell or a solicitation of an offer to buy or sell any bonds in any jurisdiction where such offer or sale is prohibited. Please read the important information and qualifications on page 2 of this Preliminary Term Sheet.

This Preliminary Term Sheet is not required to contain all information that is required to be included in the prospectus for the securities offering to which this Preliminary Term Sheet relates. The prospectus contains material information not contained herein, and the prospective purchasers are referred to the prospectus, including the final prospectus. This Preliminary Term Sheet is not an offer to sell or a solicitation of an offer to buy these securities in any jurisdiction where such offer, solicitation or sale is not permitted.

The information in this Preliminary Term Sheet is preliminary and may be superseded by an additional term sheet provided to you prior to the time you enter into a contract of sale. This Preliminary Term Sheet is being delivered to you solely to provide you with information about the offering of the securities referred to herein. The securities are being offered when, as and if issued. In particular, you are advised that these securities, and the fixed recovery charges securing them, are subject to modification or revision (including, among other things, the possibility that one or more tranches of securities may be split, combined or eliminated), at any time prior to issuance or availability of a final prospectus. As a result, you may commit to purchase securities that have characteristics that may change, and you are advised that all or a portion of the securities may not be issued that have the characteristics described in these materials. The Issuing Entity’s obligation to sell securities to you is conditioned on the securities and the underlying transaction having the characteristics described in these materials.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR DETERMINED IF THIS PRELIMINARY TERM SHEET IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Price and availability of the bonds are subject to change without notice.

A contract of sale will come into being no sooner than the date on which the relevant tranche of the bonds has been priced and the underwriters have confirmed the allocation of securities to be made to you; any “indications of interest” expressed by you, and any “soft circles” generated by the underwriters, will not create binding contractual obligations for you or the underwriters (or any other person or entity). You may withdraw your offer to purchase securities at any time prior to the underwriters’ acceptance of your offer.

Any legends, disclaimers or other notices that may appear at the bottom of the email communication to which this Preliminary Term Sheet is attached relating to (i) these materials not constituting an offer (or a solicitation of an offer), (ii) no representation that these materials are accurate or complete and may not be updated or (iii) these materials possibly being confidential are not applicable to these materials and should be disregarded.

For the purposes of preparing the above chart, the following assumptions, among others, have been made: (i) in relation to the initial forecast, the forecast error stays constant over the life of the bonds and is equal to an overestimate of electricity consumption of 5% (2.92 standard deviations from mean) or 15% (6.61 standard deviations from mean), (ii) the servicer makes timely and accurate filings to true-up the fixed recovery charges annually, (iii) customer write-off rates are held constant at 0.36% for all FRC consumer classes, (iv) customers remit all fixed recovery charges 42.86 days after such charges are billed, (v) operating expenses are equal to projections, (vi) there is no acceleration of the final maturity date of the bonds, (vii) a permanent loss of all customers has not occurred, and (viii) the issuance date of the bonds is April 27, 2023. There can be no assurance that the weighted average lives of the bonds will be as shown.
