Terms of the Notes

The Auto-Callable Notes Linked to the Least Performing of the Russell 2000^® Index, the S&P 500^® Index and the Nasdaq-100^® Index (the “Notes”) will be automatically called at an amount equal to the applicable Call Amount if the Observation Value of each Underlying on any Observation Date is greater than or equal to its Call Value. No further amounts will be payable following an Automatic Call. If your Notes are not called prior to maturity, if the Ending Value of each Underlying is greater than or equal to its Starting Value, at maturity, you will receive $1,387.50 per $1,000 in principal amount of your Notes. However, if the Notes are not automatically called prior to maturity and the Least Performing Underlying is less than its Threshold Value, there is full exposure to declines in the Least Performing Underlying, and you will lose some or all of your investment in the Notes. Otherwise, at maturity you will receive the principal amount.

Risk Factors

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

Any positive investment return on the Notes is limited.

The Notes do not bear interest.

The Call Amount or Redemption Amount, as applicable, will not reflect the levels of the Underlyings other than on the Observation Dates and the Valuation Date.

Because the Notes are linked to the least performing (and not the average performance) of the Underlyings, you may not receive any return on the Notes and may lose some or all of your principal amount even if the Observation Value or Ending Value of one Underlying is always greater than or equal to its Call Value or Threshold Value, as applicable.

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

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

Any payment on the Notes is subject to the credit risk of BofA Finance and the Guarantor, and any actual or perceived changes in BofA Finance’s or the Guarantor’s creditworthiness are expected to affect the value of the Notes.

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

We cannot assure you that a trading market for your Notes will ever develop or be maintained.

The Notes are subject to risks associated with small-size capitalization companies.

The Notes are subject to risks associated with foreign securities markets.

You may revoke your offer to purchase the Notes at any time prior to the time at which we accept such offer on the date the Notes are priced. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to their issuance. In the event of any changes to the terms of the Notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.
