Terms of the Notes

The Auto-Callable Notes Linked to the Least Performing of the TOPIX^® Index, the iShares^® MSCI Emerging Markets ETF and the iShares^® Russell 2000^® Value ETF (the “Notes”) will be automatically called at an amount equal to the applicable Call Amount if the Observation Value of each Underlying is greater than or equal to its Call Value on any Call Observation Date. Assuming your Notes are not called prior to maturity, if the Ending Value of the Least Performing Underlying is greater than or equal to its Redemption Barrier, at maturity, you will receive $1,700.00 per $1,000.00 in principal amount of your Notes. However, if the Notes are not automatically called prior to maturity and the Ending Value of the Least Performing Underlying is less than its Redemption Barrier, there is full exposure to declines in the Least Performing Underlying, and you will lose a significant portion or all of your investment in the Notes.

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 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.

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

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 a significant portion or all of your investment in the Notes even if the Observation Value or Ending Value of one Underlying is greater than or equal to its Call Value or Redemption Barrier, as applicable.

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 foreign currency exchange rate risk.

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

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

There are risks associated with emerging markets.

The performance of the EEM or the IWN may not correlate with the performance of its respective underlying index as well as its respective net asset value per share or unit, especially during periods of market volatility.

The anti-dilution adjustments will be limited.

The publisher or the sponsor or investment advisor of an Underlying may adjust that Underlying in a way that affects its values, and the publisher or the sponsor or investment advisor has no obligation to consider your interests.

Governmental regulatory actions could result in material changes to the composition of the EEM and could negatively affect your return on the Notes.
