Description of Terms
●   
Linked to the KraneShares CSI China Internet ETF
●   
Unlike ordinary debt Securities, the Securities do not pay interest, do not repay a fixed amount of principal at maturity and are subject to potential automatic call upon the terms described below.  Any return you receive on the Securities and whether they are automatically called will depend on the performance of the Underlying
●   
Automatic Call. If the Fund Closing Price of the Underlying on any Observation Date is greater than or equal to the Starting Value, the Securities will be automatically called, and on the related Call Settlement Date, you will receive the principal amount plus the Call Premium applicable to that Observation Date. The Call Premium applicable to each Observation Date will be a percentage of the principal amount that increases for each Observation Date based on a simple (non-compounding) return of approximately 11.50% to approximately 13.50% per annum (to be determined on the pricing date)
Observation Date* Call Premium**
December 5, 2022 11.50% – 13.50% of the principal amount
December 4, 2023 23.00% - 27.00% of the principal amount
December 3, 2024 34.50% – 40.50% of the principal amount
November 25, 2025 46.00% - 54.00% of the principal amount
** the actual Call Premium applicable to each Observation Date will be determined on the pricing date
●   
Redemption Amount. If the Securities are not automatically called, you will receive a Redemption Amount that could be equal to or less than the principal amount per Security depending on the Fund Closing Price of the Underlying on the Valuation Date as follows:
o   If the price of the Underlying decreases but the decrease is not more than 10%:
You will receive the principal amount of your Securities at maturity
o   If the price of the Underlying decreases by more than 10%:
You will receive less than the principal amount and have 1-to-1 downside exposure to the decrease in the level of the Underlying in excess of 10%
●   
Investors may lose up to 90% of the principal amount
●   
Any positive return on the Securities will be limited to the applicable Call Premium
●   
All payments on the Securities are subject to the credit risk of BofA Finance LLC, as issuer, and Bank of America Corporation, as guarantor, and you will have no ability to pursue any shares of the Underlying or securities included in the Underlying for payment; if BofA Finance LLC, as issuer, and Bank of America Corporation, as guarantor, default on their respective obligations, you could lose some or all of your investment
●   
No exchange listing; designed to be held to maturity


 
The initial estimated value of the Securities as of the pricing date is expected to be between $920 and $970 per Security, which is less than the public offering price. The actual value of your Securities at any time will reflect many factors and cannot be predicted with accuracy. See “Risk Factors” beginning on page PS-8 of the accompanying preliminary pricing supplement and “Structuring the Securities” on page PS-25 of the accompanying preliminary pricing supplement for additional information.
The Securities have complex features and investing in the Securities involves risks not associated with an investment in conventional debt securities. Potential purchasers of the Securities should consider the information in “Risk Factors” beginning on page PS-8 of the accompanying preliminary pricing supplement, page PS-5 of the accompanying product supplement, page S-5 of the accompanying prospectus supplement, and page 7 of the accompanying prospectus.
This introductory term sheet does not provide all of the information that an investor should consider prior to making an investment decision.
Investors should carefully review the accompanying preliminary pricing supplement, product supplement, prospectus supplement and prospectus before making a decision to invest in the Securities. 
NOT A BANK DEPOSIT AND NOT INSURED OR GUARANTEED BY THE FDIC OR ANY OTHER GOVERNMENTAL AGENCY
Hypothetical Payout Profile
The profile to the right illustrates the potential payment on the Securities for a range of hypothetical percentage changes in the Fund Closing Price of the Underlying from the pricing date to the applicable Observation Date. The profile is based on a hypothetical Call Premium of 12.50% for the first Observation Date, 25.00% for the second Observation Date, 37.50% for the third Observation Date and 50.00% for the fourth Observation Date (based on the midpoint of the ranges specified for the Call Premiums) and a Threshold Value equal to 90% of the Starting Value. 
This profile has been prepared for purposes of illustration only. Your actual return will depend on (i) whether the Securities are automatically called; (ii) if the Securities are automatically called, the actual Call Premium and the actual Observation Date on which the Securities are called; (iii) if the Securities are not automatically called, the actual Ending Value of the Underlying; and (iv) whether you hold your Securities to maturity or earlier automatic call.

Observation Dates and Call Premiums
The Call Premium applicable to each Observation Date will be a percentage of the principal amount that increases for each Observation Date based on a simple (non-compounding) return of approximately 11.50% to approximately 13.50% per annum (to be determined on the pricing date). The actual Call Premium and payment per Security upon an automatic call that is applicable to each Observation Date will be determined on the pricing date and will be within the ranges specified in the table below. The last Observation Date is the Valuation Date, and payment upon an automatic call on the Valuation Date, if applicable, will be made on the Maturity Date.
Observation Date
Call Premium
Payment per Security upon an Automatic Call
December 5, 2022
11.50% — 13.50% of the principal amount
$1,115.00 — $1,135.00
December 4, 2023
23.00% - 27.00% of the principal amount
$1,230.00 — $1,270.00
December 3, 2024
34.50% — 40.50% of the principal amount

November 25, 2025 (the “Valuation Date”)
46.00% - 54.00% of the principal amount
$1,460.00 — $1,540.00
Any positive return on the Securities will be limited to the applicable Call Premium, even if the Closing Price of the Underlying significantly exceeds the Starting Value on the applicable Observation Date. You will not participate in any appreciation of the Underlying beyond the applicable Call Premium.
How The Redemption Amount Is Calculated
If the Securities are not automatically called, then on the Maturity Date you will receive a cash payment per Security equal to the Redemption Amount. The Redemption Amount per Security will equal:
●   
If the Ending Value is less than the Starting Value but greater than or equal to the Threshold Value: $1,000; or
●   
If the Ending Value is less than the Threshold Value: $1,000 minus 

If the Securities are not automatically called and the Ending Value is less than the Threshold Value, you will receive less, and possibly 90% less, than the principal amount of your securities at maturity.

●   
The Securities do not bear interest.
●   
The Call Premium or Redemption Amount, as applicable, will not reflect the prices of the Underlying other than on the Observation Dates.

Your return on the Securities may be less than the yield on a conventional debt security of comparable maturity.

Any payment on the Securities is subject to our credit risk and the credit risk of the Guarantor, and actual or perceived changes in our or the Guarantor’s creditworthiness are expected to affect the value of the Securities.
●   
BofA Finance is a finance subsidiary and, as such, has no independent assets, operations or revenues.

The public offering price you pay for the Securities will exceed their initial estimated value. 
●

●   
BofA Finance cannot assure you that a trading market for your Securities will ever develop or be maintained.

Adverse conditions in the internet sector may reduce your return on the Securities.

●   
The anti-dilution adjustments will be limited.
