Description of Terms

· Linked to the SPDR^® S&P^® Biotech 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 10.00% per annum

Observation Date	Call Premium
November 2, 2022	10.00% of the principal amount
November 2, 2023	20.00% of the principal amount
October 28, 2024 (the “Valuation Date”)	30.00% of the principal amount

· 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 25%:

You will receive the principal amount of your Securities at maturity

o If the price of the Underlying decreases by more than 25%:

You will lose more than 25%, and possibly all, of the principal amount of your Securities.

· Investors may lose up to 100% 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 $953.30 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 pricing supplement and “Structuring the Securities” on page PS-24 of the accompanying 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 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 final term sheet should be read in conjunction with the accompanying 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 the Call Premium of 10.00% for the first Observation Date, 20.00% for the second Observation Date, and 30.00% for the final Observation Date and a Threshold Value equal to 75% 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 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.

Hypothetical Returns

If the Securities are automatically called:

Hypothetical Observation Date on which Securities are automatically called	Payment per Security on related Call Settlement Date	Pre-tax total rate of return
1st Observation Date	$1,100.00	10.00%
2nd Observation Date	$1,200.00	20.00%
3rd Observation Date	$1,300.00	30.00%

Each security has a principal amount of $1,000.

If the Securities are not automatically called:

Hypothetical Ending Value	Hypothetical percentage change from the hypothetical Starting Value to the hypothetical Ending Value	Hypothetical Redemption Amount per Security	Hypothetical pre-tax total rate of return
$95.00	-5.00%	$1,000.00	0.00%
$90.00	-10.00%	$1,000.00	0.00%
$75.00	-25.00%	$1,000.00	0.00%
$74.00	-26.00%	$740.00	-26.00%
$50.00	-50.00%	$500.00	-50.00%
$25.00	-75.00%	$250.00	-75.00%
$0.00	-100.00%	$0.00	-100.00%

Assumes a hypothetical Starting Value of $100.00. The hypothetical Starting Value of $100.00 has been chosen for illustrative purposes only and does not represent the actual Starting Value. The actual Starting Value and Threshold Value are set forth under “Summary of Terms” above. For historical data regarding the actual Closing Prices of the Underlying, see the historical information set forth under the section titled “The SPDR^® S&P^® Biotech ETF” in the accompanying pricing supplement. Each security has a principal amount of $1,000.

The above figures are for purposes of illustration only and may have been rounded for ease of analysis. The actual payment per Security upon automatic call or Redemption Amount and the resulting pre-tax rate of return will depend on (i) whether the Securities are automatically called; (ii) if the Securities are automatically called, the actual Observation Date on which the Securities are called; and (iii) if the Securities are not automatically called, the actual Starting Value and actual Ending Value.

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 10.00% per annum. The actual Call Premium and payment per Security upon an automatic call that is applicable to each Observation Date were determined on the pricing date and are 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
November 2, 2022	10.00% of the principal amount	$1,100.00
November 2, 2023	20.00% of the principal amount	$1,200.00
October 28, 2024 (the “Valuation Date”)	30.00% of the principal amount	$1,300.00

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 lose more than 25%, and possibly all, of the principal amount of your Securities on the Maturity Date.

Selected Risk Considerations

The risks set forth below are discussed in detail in the “Risk Factors” section in the accompanying pricing supplement. Please review those risk disclosures carefully.

· Your investment may result in a loss; there is no guaranteed return of principal.

· Any positive investment return on the Securities is limited.

· 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.

· The Securities are subject to a potential Automatic Call, which would limit your ability to receive further payment on the Securities.

· 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 are paying for the Securities exceeds their initial estimated value.

· The initial estimated value does not represent a minimum or maximum price at which BofA Finance, BAC, BofAS or any of our other affiliates or WFS or its affiliates would be willing to purchase your Securities in any secondary market (if any exists) at any time.

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

· The Securities are not designed to be short-term trading instruments, and if you attempt to sell the Securities prior to maturity, their market value, if any, will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount. 

· Trading and hedging activities by BofA Finance, the Guarantor and any of our other affiliates, including BofAS, and WFS and its affiliates, may create conflicts of interest with you and may affect your return on the Securities and their market value.

· There may be potential conflicts of interest involving the calculation agent, which is an affiliate of ours.

· The stocks held by the Underlying are concentrated in one sector.

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

· The anti-dilution adjustments will be limited.

· The performance of the Underlying may not correlate with the performance of its underlying index as well as the net asset value per share of the Underlying, especially during periods of market volatility.

· The U.S. federal income tax consequences of an investment in the Securities are uncertain, and may be adverse to a holder of the Securities.

Not appropriate for all investors

Investment suitability must be determined individually for each investor. The Securities described herein are not an appropriate investment for all investors. In particular, no investor should purchase the Securities unless they understand and are able to bear the associated market, liquidity and yield risks. Unless market conditions and other relevant factors change significantly in your favor, a sale of the Securities prior to maturity is likely to result in sale proceeds that are substantially less than the principal amount per Security. BofAS, Wells Fargo Securities and their affiliates are not obligated to purchase the Securities from you at any time prior to maturity.
