Rhea-AI Filing Summary

Bank of Montreal (BMO) is offering US$822,000 aggregate principal amount of Senior Medium-Term Notes, Series K, titled Autocallable Barrier Notes with Memory Coupons due July 14, 2028 and linked to the common stock of ON Semiconductor Corporation ("ON"). The notes are unsecured obligations of BMO and are not listed on any exchange.

Core economic terms

• Denomination: minimum $1,000, CUSIP 06376ER87.
• Pricing Date: 9 Jul 2025; Settlement: 14 Jul 2025; Maturity: 14 Jul 2028.
• Initial Level: $54.61 (ON share price on the Strike Date).
• Contingent Interest Rate: 3.8375 % per quarter (~15.35 % p.a.) paid only if ON’s closing level on an Observation Date is ≥ the Coupon Barrier ($40.96, 75 % of Initial).
• Memory Coupon: any missed coupon is paid later if a subsequent Observation Date is at or above the Coupon Barrier.
• Automatic Redemption (Autocall): from the first Observation Date (9 Oct 2025), the notes are redeemed at par plus accrued coupon if ON closes ≥ the Call Level (100 % of Initial).
• Principal at risk: If not called and ON’s Final Level on 11 Jul 2028 is < Trigger Level ($27.31, 50 % of Initial), investors lose 1 % of principal for each 1 % decline from Initial; loss can reach 100 %.
• Estimated initial value: $951.28 per $1,000 (reflects fees & hedging costs); price to public: 100 %.
• Agent’s commission: 2.25 %; select dealers may receive up to 0.80 % referral fee.

Key risks disclosed

• No principal protection; potential full loss if ON drops ≥50 % at maturity.
• No guarantee of coupons; payments depend on ON staying ≥ Coupon Barrier.
• Limited upside: maximum return equals sum of coupons; no participation in ON appreciation.
• Credit exposure to BMO; notes are senior but unsecured.
• Illiquidity: no listing; secondary market, if any, is at BMOCM’s discretion and likely below par.
• Initial estimated value is below issue price, indicating embedded costs.
• Tax treatment uncertain; intended to be prepaid contingent income-bearing derivative contracts.

These notes may appeal to income-oriented investors who are moderately bullish to neutral on ON over the next three years and who are comfortable with issuer credit risk and potential loss of principal.

Positive

• High contingent coupon: 3.8375 % per quarter (~15.35 % p.a.) if ON stays ≥ 75 % of the Initial Level.
• Memory feature: missed coupons can be recovered if the barrier is later breached on the upside.
• Early redemption: investors recover principal plus coupon if ON closes at or above Initial Level on any quarterly observation.

Negative

• No principal protection: 1:1 downside below a 50 % trigger, exposing investors to full capital loss.
• Limited upside: maximum return is capped at cumulative coupons; no participation in ON price appreciation.
• Issuer credit risk: payments rely on Bank of Montreal’s ability to pay; notes are unsecured.
• Estimated value below par: initial fair value is $951.28 vs. $1,000 issue price, embedding ~4.9 % in costs.
• Illiquidity: no exchange listing; secondary market solely at BMOCM’s discretion and likely at a discount.

Insights

Structured-Products Analyst

TL;DR: High coupon offsets high equity and credit risk; payoff capped, downside significant.

The 15.35 % annual contingent coupon is attractive versus conventional debt, but payment requires ON to stay above 75 % of its July 2025 price. Memory feature helps, yet a prolonged drop below the barrier eliminates income until recovery. Autocall at 100 % means investors could be redeemed early—locking in limited returns just when ON strength improves. Principal is unprotected; a sub-50 % finish results in linear losses, fully erasing capital if ON falls 50 % or more. With the initial value at 95.128 % of par and 2.25 % selling concession, investors pay a sizable premium for optionality that favors the issuer. Liquidity is dealer-driven and likely thin. Overall risk-reward suits tactical investors with a defined view on ON and acceptance of BMO credit exposure.

Credit & Risk Specialist

TL;DR: Routine issuance; material to buyers, immaterial to BMO balance sheet.

At only US$0.8 million aggregate, this tranche is de-minimis for BMO’s funding mix and will not move its credit profile. From a buyer’s stance, risk layering is substantial: equity volatility, issuer credit, liquidity, and tax uncertainty. The 50 % trigger aligns with typical U.S. single-stock autocall structures, but ON is a cyclical semiconductor name with historical volatility that can breach such levels. The note’s risk premium is therefore warranted, yet investors should stress-test ON’s downside scenarios. Given the limited size and standard terms, market impact is negligible; classification: not impactful for BMO or ON equity.

US$ 539,000
Senior Medium-Term Notes, Series K
Autocallable Barrier Notes with Memory Coupons due July 14, 2028
Linked to the common stock of Royal Caribbean Cruises Ltd.

· The notes are designed for investors who are seeking quarterly contingent periodic interest payments (as described in more detail below), as well as a return of principal if the closing level of the common stock of Royal Caribbean Cruises Ltd. (the “Reference Asset”) on any quarterly Observation Date beginning in October 2025 is greater than 100% of its Initial Level (the “Call Level”). Investors should be willing to have their notes automatically redeemed prior to maturity, be willing to forego any potential to participate in the appreciation of the Reference Asset and be willing to lose some or all of their principal at maturity.

· The notes may pay Contingent Coupons at the Contingent Interest Rate of 3.175% per quarter (approximately 12.70% per annum) depending on the performance of the Reference Asset. If the closing level of the Reference Asset on the applicable quarterly Observation Date is greater than or equal to its Coupon Barrier Level, the notes will pay (i) a Contingent Coupon on the corresponding Contingent Coupon Payment Date and (ii) and previously unpaid Contingent Coupons in respect of any prior Observation Dates pursuant to the Memory Coupon Feature. If the closing level of the Reference Asset is less than its Coupon Barrier Level on an Observation Date, the notes will not pay the Contingent Coupon on the corresponding Contingent Coupon Payment Date.

· Beginning on October 09, 2025, if on any Observation Date, the closing level of the Reference Asset is greater than its Call Level, the notes will be automatically redeemed. On the following Contingent Coupon Payment Date (the “Call Settlement Date"), investors will receive their principal amount plus the Contingent Coupon otherwise due. After the notes are redeemed, investors will not receive any additional payments in respect of the notes.

· The notes do not guarantee any return of principal at maturity. Instead, if the notes are not automatically redeemed, the payment at maturity will be based on the Final Level of the Reference Asset and whether the Final Level of that Reference Asset has declined from its Initial Level to below its Trigger Level on the Valuation Date (a “Trigger Event”), as described below.

· If the notes are not automatically redeemed and a Trigger Event has occurred, investors will lose 1% of the principal amount for each 1% decrease in the level of the Reference Asset from its Initial Level to its Final Level. In such a case, you will receive a cash amount at maturity that is less than the principal amount, together with the final Contingent Coupon, if payable.

· Investing in the notes is not equivalent to a direct investment in the Reference Asset.

· The notes will not be listed on any securities exchange.

· All payments on the notes are subject to the credit risk of Bank of Montreal.

· The notes will be issued in minimum denominations of $1,000 and integral multiples of $1,000.

· Our subsidiary, BMO Capital Markets Corp. (“BMOCM”), is the agent for this offering. See “Supplemental Plan of Distribution (Conflicts of Interest)” below.

· The notes will not be subject to conversion into our common shares or the common shares of any of our affiliates under subsection 39.2(2.3) of the Canada Deposit Insurance Corporation Act (the “CDIC Act”).

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the Reference Asset. These risks are explained in more detail in the “Additional Risk Factors Relating to the Notes” section of the product supplement.

Risks Related to the Structure or Features of the Notes

· Your investment in the notes may result in a loss. — The notes do not guarantee any return of principal. If the notes are not automatically redeemed, the payment at maturity will be based on the Final Level and whether a Trigger Event has occurred. If the Final Level is less than its Trigger Level, a Trigger Event will occur, and you will lose 1% of the principal amount for each 1% that the Final Level is less than the Initial Level. In such a case, you will receive at maturity a cash payment that is less than the principal amount of the notes and may be zero. Accordingly, you could lose your entire investment in the notes.

· You may not receive any Contingent Coupons with respect to your notes. — We will not necessarily make periodic interest payments on the notes. If the closing level of the Reference Asset on an Observation Date is less than its Coupon Barrier Level, we will not pay you the Contingent Coupon on the corresponding Contingent Coupon Payment Date. However, if a Contingent Coupon is not paid on a Contingent Coupon Payment Date (other than the Maturity Date) because the closing level of the Reference Asset is less than the Coupon Barrier Level on the related Observation Date, pursuant to the Memory Coupon Feature such Contingent Coupon will be paid on a later Contingent Coupon Payment Date if the closing level of the Reference Asset is greater than or equal to its Coupon Barrier Level on the related Observation Date. If the closing level of the Reference Asset is less than its Coupon Barrier Level on each of the Observation Dates, we will not pay you any Contingent Coupons during the term of the notes, and you will not receive a positive return on the notes. Generally, this non-payment of any Contingent Coupons will coincide with a greater risk of principal loss on your notes.

· Your notes are subject to automatic early redemption. — We will redeem the notes if the closing level of the Reference Asset on any Observation Date is greater than its Call Level. Following an automatic redemption, you will not receive any additional Contingent Coupons and may not be able to reinvest your proceeds in an investment with returns that are comparable to the notes. Furthermore, to the extent you are able to reinvest such proceeds in an investment with a comparable return for a similar level of risk, you may incur transaction costs such as dealer discounts and hedging costs built into the price of the new notes.

· Your return on the notes is limited to the Contingent Coupons, if any, regardless of any appreciation in the value of the Reference Asset. — You will not receive a payment at maturity with a value greater than your principal amount plus any Contingent Coupons otherwise due . In addition, if the notes are automatically redeemed, you will not receive a payment greater than the principal amount plus any applicable Contingent Coupons, even if the Final Level exceeds the Call Level by a substantial amount. Accordingly, your maximum return on the applicable notes is limited to the potential return represented by the Contingent Coupons.

· Your return on the notes may be lower than the return on a conventional debt security of comparable maturity. — The return that you will receive on your notes, which could be negative, may be less than the return you could earn on other investments. The notes do not provide for fixed interest payments and you may not receive any Contingent Coupons over the term of the notes. Even if you do receive one or more Contingent Coupons and your return on the notes is positive, your return may be less than the return you would earn if you bought a conventional senior interest bearing debt security of ours with the same maturity or if you invested directly in the Reference Asset. Your investment may not reflect the full opportunity cost to you when you take into account factors that affect the time value of money.

· A higher Contingent Interest Rate or lower Trigger Level or Coupon Barrier Level may reflect greater expected volatility of the Reference Asset, and greater expected volatility generally indicates an increased risk of loss at maturity. — The economic terms for the notes, including the Contingent Interest Rate, Coupon Barrier Level and Trigger Level, are based, in part, on the expected volatility of the Reference Asset at the time the terms of the notes are set. “Volatility” refers to the frequency and magnitude of changes in the level of the Reference Asset. The greater the expected volatility of the Reference Asset as of the Pricing Date, the greater the expectation is as of that date that the closing level of the Reference Asset could be less than its Coupon Barrier Level on any Observation Date and that a Trigger Event could occur and, as a consequence, indicates an increased risk of not receiving a Contingent Coupon and an increased risk of loss, respectively. All things being equal, this greater expected volatility will generally be reflected in a higher Contingent Interest Rate than the yield payable on our conventional debt securities with a similar maturity or on otherwise comparable securities, and/or lower Trigger Level and/or Coupon Barrier Level than those terms on otherwise comparable securities. Therefore, a relatively higher Contingent Interest Rate may indicate an increased risk of loss. Further, a relatively lower Trigger Level and/or Coupon Barrier may not necessarily indicate that the notes have a greater likelihood of a return of principal at maturity and/or paying Contingent Coupons. You should be willing to accept the downside market risk of the Reference Asset and the potential to lose a significant portion or all of your initial investment.

Risks Related to the Reference Asset

· Owning the notes is not the same as owning shares of the Reference Asset or a security directly linked to the Reference Asset. — The return on your notes will not reflect the return you would realize if you actually owned shares of the Reference Asset or a security directly linked to the performance of the Reference Asset and held that investment for a similar period. Your notes may trade quite differently from the Reference Asset. Changes in the level of the Reference Asset may not result in comparable changes in the market value of your notes. Even if the level of the Reference Asset increases during the term of the notes, the market value of the notes prior to maturity may not increase to the same extent. It is also possible for the market value of the notes to decrease while the level of the Reference Asset increases. In addition, any dividends or other distributions paid on the Reference Asset will not be reflected in the amount payable on the notes.

· You will not have any shareholder rights and will have no right to receive any shares of the Reference Asset at maturity. — Investing in your notes will not make you a holder of any shares of the Reference Asset. Neither you nor any other holder or owner of the notes will have any voting rights, any right to receive dividends or other distributions, or any other rights with respect to the Reference Asset.

· No delivery of shares of the Reference Asset. — The notes will be payable only in cash. You should not invest in the notes if you seek to have the shares of the Reference Asset delivered to you at maturity.

· Single equity risk. — The level of the Reference Asset can rise or fall sharply due to factors specific to the Reference Asset and the issuer of the Reference Asset (the “Reference Asset Issuer”), such as stock price volatility, earnings, financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market volatility and levels, interest rates and economic and political conditions. We urge you to review financial and other information filed periodically with the SEC by the Reference Asset Issuer. We are not affiliated with the Reference Asset Issuer and are not responsible for the Reference Asset Issuer’s public disclosure of information, whether contained in SEC filings or otherwise. We have not undertaken any independent review or due diligence of the SEC filings of the Reference Asset Issuer or of any other publicly available information regarding the Reference Asset Issuer.

· You must rely on your own evaluation of the merits of an investment linked to the Reference Asset. — In the ordinary course of their businesses, our affiliates from time to time may express views on expected movements in the level of the Reference Asset. One or more of our affiliates have published, and in the future may publish, research reports that express views on the Reference Asset. However, these views are subject to change from time to time. Moreover, other professionals who deal in the markets relating to the Reference Asset at any time may have significantly different views from those of our affiliates. You are encouraged to derive information concerning the Reference Asset from multiple sources, and you should not rely on the views expressed by our affiliates.
Neither the offering of the notes nor any views which our affiliates from time to time may express in the ordinary course of their businesses constitutes a recommendation as to the merits of an investment in the notes.

General Risk Factors

· Your investment is subject to the credit risk of Bank of Montreal. — Our credit ratings and credit spreads may adversely affect the market value of the notes. Investors are dependent on our ability to pay any amounts due on the notes, and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. Any decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the value of the notes.

· Potential conflicts. — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. We or one or more of our affiliates may also engage in trading of shares of the Reference Asset on a regular basis as part of our general broker-dealer and other businesses, for proprietary accounts, for other accounts under management or to facilitate transactions for our customers. Any of these activities could adversely affect the level of the Reference Asset and, therefore, the market value of, and the payments on, the notes. We or one or more of our affiliates may also issue or underwrite other securities or financial or derivative instruments with returns linked or related to changes in the performance of the Reference Asset. By introducing competing products into the marketplace in this manner, we or one or more of our affiliates could adversely affect the market value of the notes.

· Our initial estimated value of the notes is lower than the price to public. — Our initial estimated value of the notes is only an estimate, and is based on a number of factors. The price to public of the notes exceeds our initial estimated value, because costs associated with offering, structuring and hedging the notes are included in the price to public, but are not included in the estimated value. These costs include any underwriting discount and selling concessions, the profits that we and our affiliates expect to realize for assuming the risks in hedging our obligations under the notes and the estimated cost of hedging these obligations.

· Our initial estimated value does not represent any future value of the notes, and may also differ from the estimated value of any other party. — Our initial estimated value of the notes as of the date hereof is derived using our internal pricing models. This value is based on market conditions and other relevant factors, which include volatility of the Reference Asset, dividend rates and interest rates. Different pricing models and assumptions could provide values for the notes that are greater than or less than our initial estimated value. In addition, market conditions and other relevant factors after the Pricing Date are expected to change, possibly rapidly, and our assumptions may prove to be incorrect. After the Pricing Date, the value of the notes could change dramatically due to changes in market conditions, our creditworthiness, and the other factors set forth herein and in the product supplement. These changes are likely to impact the price, if any, at which we or BMOCM would be willing to purchase the notes from you in any secondary market transactions. Our initial estimated value does not represent a minimum price at which we or our affiliates would be willing to buy your notes in any secondary market at any time.

· The terms of the notes were not determined by reference to the credit spreads for our conventional fixed-rate debt. — To determine the terms of the notes, we used an internal funding rate that represents a discount from the credit spreads for our conventional fixed-rate debt. As a result, the terms of the notes are less favorable to you than if we had used a higher funding rate.

· Certain costs are likely to adversely affect the value of the notes. — Absent any changes in market conditions, any secondary market prices of the notes will likely be lower than the price to public. This is because any secondary market prices will likely take into account our then-current market credit spreads, and because any secondary market prices are likely to exclude all or a portion of any underwriting discount and selling concessions, and the hedging profits and estimated hedging costs that are included in the price to public of the notes and that may be reflected on your account statements. In addition, any such price is also likely to reflect a discount to account for costs associated with establishing or unwinding any related hedge transaction, such as dealer discounts, mark-ups and other transaction costs. As a result, the price, if any, at which BMOCM or any other party may be willing to purchase the notes from you in secondary market transactions, if at all, will likely be lower than the price to public. Any sale that you make prior to the Maturity Date could result in a substantial loss to you.

· Lack of liquidity. — The notes will not be listed on any securities exchange. BMOCM may offer to purchase the notes in the secondary market, but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade the notes is likely to depend on the price, if any, at which BMOCM is willing to buy the notes.

· Hedging and trading activities. — We or any of our affiliates have carried out or may carry out hedging activities related to the notes, including purchasing or selling shares of the Reference Asset, futures or options relating to the Reference Asset or other derivative instruments with returns linked or related to changes in the performance on the Reference Asset. We or our affiliates may also trade in the Reference Asset or instruments related to the Reference Asset from time to time. Any of these hedging or trading activities on or prior to the Pricing Date and during the term of the notes could adversely affect the payments on the notes.

· Many economic and market factors will influence the value of the notes. — In addition to the level of the Reference Asset and interest rates on any trading day, the value of the notes will be affected by a number of economic and market factors that may either offset or magnify each other, and which are described in more detail in the product supplement.

· Significant aspects of the tax treatment of the notes are uncertain. — The tax treatment of the notes is uncertain. We do not plan to request a ruling from the Internal Revenue Service or from any Canadian authorities regarding the tax treatment of the notes, and the Internal Revenue Service or a court may not agree with the tax treatment described herein.

The Internal Revenue Service has released a notice that may affect the taxation of holders of “prepaid forward contracts” and similar instruments. According to the notice, the Internal Revenue Service and the U.S. Treasury are actively considering whether the holder of such instruments should be required to accrue ordinary income on a current basis. While it is not clear whether the notes would be viewed as similar to such instruments, it is possible that any future guidance could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect.
Please read carefully the section entitled "U.S. Federal Tax Information" herein, the section entitled "Supplemental Tax Considerations–Supplemental U.S. Federal Income Tax Considerations" in the accompanying product supplement, the section entitled "United States Federal Income Taxation" in the accompanying prospectus and the section entitled "Certain Income Tax Consequences" in the accompanying prospectus supplement. You should consult your tax advisor about your own tax situation.

Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in the Notes

The following table illustrates the hypothetical payments on a note at maturity, assuming that the notes are not automatically redeemed. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of $100.00, a hypothetical Trigger Level of $60.00 (60.00% of the hypothetical Initial Level), a hypothetical Call Level of $100.00 (100.00% of the hypothetical Initial Level), a range of hypothetical Final Levels and the effect on the payment at maturity .

The hypothetical examples shown below are intended to help you understand the terms of the notes. If the notes are not automatically redeemed, the actual cash amount that you will receive at maturity will depend upon the Final Level of the Reference Asset. If the notes are automatically redeemed prior to maturity, the hypothetical examples below will not be relevant, and you will receive on the applicable Call Settlement Date, for each $1,000 principal amount, the principal amount plus any Contingent Coupons otherwise due .

As discussed in more detail above, your total return on the notes will also depend on the number of Contingent Coupon Dates on which the Contingent Coupon is payable. It is possible that the only payments on your notes will be the payment, if any, due at maturity. The payment at maturity will not exceed the principal amount, and may be significantly less.

U.S. Federal Tax Information

By purchasing the notes, each holder agrees (in the absence of a change in law, an administrative determination or a judicial ruling to the contrary) to treat each note as a pre-paid contingent income-bearing derivative contract for U.S. federal income tax purposes. In the opinion of our counsel, Mayer Brown LLP, it would generally be reasonable to treat the notes as pre-paid contingent income-bearing derivative contracts in respect of the Reference Asset for U.S. federal income tax purposes. However, the U.S. federal income tax consequences of your investment in the notes are uncertain and the Internal Revenue Service could assert that the notes should be taxed in a manner that is different from that described in the preceding sentence. Please see the discussion in the accompanying product supplement under "Supplemental Tax Considerations—Supplemental U.S. Federal Income Tax Considerations—Notes Treated as Investment Units Consisting of a Debt Portion and a Put Option, as Pre-Paid Contingent Income-Bearing Derivative Contracts, or as Pre-Paid Derivative Contracts—Notes Treated as Pre-Paid Contingent Income-Bearing Derivative Contracts," which applies to the notes.

Supplemental Plan of Distribution (Conflicts of Interest)

BMOCM will purchase the notes from us at a purchase price reflecting the commission set forth on the cover hereof. BMOCM has informed us that, as part of its distribution of the notes, it will reoffer the notes to other dealers who will sell them. Each such dealer, or each additional dealer engaged by a dealer to whom BMOCM reoffers the notes, will receive a commission from BMOCM, which will not exceed the commission set forth on the cover page. We or one of our affiliates will also pay a referral fee to certain dealers of up to 0.800% of the principal amount in connection with the distribution of the notes. 

Certain dealers who purchase the notes for sale to certain fee-based advisory accounts may forego some or all of their selling concessions, fees or commissions. The public offering price for investors purchasing the notes in these accounts may be less than 100% of the principal amount, as set forth on the cover page of this document. Investors that hold their notes in these accounts may be charged fees by the investment advisor or manager of that account based on the amount of assets held in those accounts, including the notes. 

We will deliver the notes on a date that is greater than one business day following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than one business day prior to the issue date will be required to specify alternative settlement arrangements to prevent a failed settlement. 

We own, directly or indirectly, all of the outstanding equity securities of BMOCM, the agent for this offering. In accordance with FINRA Rule 5121, BMOCM may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer. 

You should not construe the offering of the notes as a recommendation of the merits of acquiring an investment linked to the Reference Asset or as to the suitability of an investment in the notes. 

BMOCM may, but is not obligated to, make a market in the notes. BMOCM will determine any secondary market prices that it is prepared to offer in its sole discretion. 

We may use this pricing supplement in the initial sale of the notes. In addition, BMOCM or another of our affiliates may use this pricing supplement in market-making transactions in any notes after their initial sale. Unless BMOCM or we inform you otherwise in the confirmation of sale, this pricing supplement is being used by BMOCM in a market-making transaction.

For a period of approximately three months following issuance of the notes, the price, if any, at which we or our affiliates would be willing to buy the notes from investors, and the value that BMOCM may also publish for the notes through one or more financial information vendors and which could be indicated for the notes on any brokerage account statements, will reflect a temporary upward adjustment from our estimated value of the notes that would otherwise be determined and applicable at that time. This temporary upward adjustment represents a portion of (a) the hedging profit that we or our affiliates expect to realize over the term of the notes and (b) any underwriting discount and the selling concessions paid in connection with this offering. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the three-month period.

Switzerland. This pricing supplement is not intended to constitute an offer or solicitation to purchase or invest in any notes. Neither this pricing supplement nor any other offering or marketing material relating to the notes constitutes a prospectus compliant with the requirements of articles 35 et seq. of the Swiss Financial Services Act ("FinSA")) for a public offering of the notes in Switzerland and no such prospectus has been or will be prepared for or in connection with the offering of the notes in Switzerland.

Neither this pricing supplement nor any other offering or marketing material relating to the notes has been or will be filed with or approved by a Swiss review body (Prüfstelle).

The notes may not be publicly offered, directly or indirectly, in Switzerland within the meaning of FinSA except (i) in any circumstances falling within the exemptions to prepare a prospectus listed in article 36 para. 1 FinSA or (ii) where such offer does not qualify as a public offer in Switzerland, provided always that no offer of notes shall require the Issuer or any offeror to publish a prospectus pursuant to article 35 FinSA in respect to such offer and that such offer shall comply with the additional restrictions set out below (if applicable). The Issuer has not authorised and does not authorise any offer of notes which would require the Issuer or any offeror to publish a prospectus pursuant to article 35 FinSA in respect of such offer. For purposes of this provision "public offer" shall have the meaning as such term is understood pursuant to article 3 lit. g and h FinSA and the Swiss Financial Services Ordinance ("FinSO").

The notes do not constitute participations in a collective investment scheme within the meaning of the Swiss Collective Investment Schemes Act. They are not subject to the approval of, or supervision by, the Swiss Financial Market Supervisory Authority ("FINMA"), and investors in the notes will not benefit from protection under CISA or supervision by FINMA.

Prohibition of Offer to Private Clients in Switzerland - No Key Information Document pursuant to article 58 FinSA (Basisinformationsblatt für Finanzinstrumente) or equivalent document under foreign law pursuant to article 59 para. 2 FinSA has been or will be prepared in relation to the notes. Therefore, the following additional restriction applies: Notes qualifying as "debt securities with a derivative character" pursuant to article 86 para. 2 FinSO may not be offered within the meaning of article 58 para. 1 FinSA, and neither this pricing supplement nor any other offering or marketing material relating to such notes may be made available, to any retail client (Privatkunde) within the meaning of FinSA in Switzerland.

Additional Information Relating to the Estimated Initial Value of the Notes

Our estimated initial value of the notes on the date hereof that is set forth on the cover hereof, equals the sum of the values of the following hypothetical components:

· a fixed-income debt component with the same tenor as the notes, valued using our internal funding rate for structured notes; and 

· one or more derivative transactions relating to the economic terms of the notes. 

The internal funding rate used in the determination of the initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The value of these derivative transactions is derived from our internal pricing models. These models are based on factors such as the traded market prices of comparable derivative instruments and on other inputs, which include volatility, dividend rates, interest rates and other factors. As a result, the estimated initial value of the notes on the Pricing Date was determined based on the market conditions on the Pricing Date.
