Credit Suisse US Balanced 5% ER Index

Underlying Performance Supplement to the Underlying Supplement Dated October 15, 2018, Prospectus Supplement and Prospectus Dated June 30, 2017

Index Description

• The Index’s portfolio is exposed to up to three “Component Indices”

• The Index’s portfolio includes equity exposure consisting of the Credit Suisse US Equity Futures Index (the “Equity Index”), and, in certain circumstances, (i) fixed income exposure consisting of the Credit Suisse 10-Year U.S. Treasury Note Futures Index (the “10Y Fixed Income Index”) and the Credit Suisse 2-Year U.S. Treasury Note Futures Index (the “2Y Fixed Income Index,” and together with the 10Y Fixed Income Index, the “Fixed Income Indices”) and (ii) non-remunerating cash

• Designed to provide exposure to a hypothetical “balanced” portfolio (consisting of the Equity Index and a momentum strategy-driven allocation to the Fixed Income Indices), while targeting a realized daily volatility of 5%

• Allocation amongst the Equity Index and the Fixed Income Indices is based on: (1) historical realized volatility of the Equity Index and (2) performance of the 10Y Fixed Income Index, as measured by a “Risk Signal”

• Index seeks to achieve a realized volatility target of 5% by varying its notional exposure to the portfolio of the Equity Index and, if applicable, the 10Y Fixed Income Index and the 2Y Fixed Income Index

• Maximum notional exposure to the portfolio of 125%

• Equity Index tracks the performance of notional long investments in E-mini S&P 500 futures contracts

• 10Y Fixed Income Index tracks the performance of notional long investment in ten-year U.S. Treasury note futures contracts

• 2Y Fixed Income Index tracks the performance of notional long investment in two-year U.S. Treasury note futures contracts

Index Profile

Name	Credit Suisse US Balanced 5% ER Index (the “Index”)
Ticker	CSEAUSB5
Launch Date	June 29, 2018
Rebalancing	Daily
Realized Volatility Target	5% Daily
Maximum Notional Exposure to Portfolio	125%
Index Fee	0.50% per annum

• The Index Does Not Attempt to Achieve a Broad or “Balanced” Asset Class Diversification. “Balanced” is not meant to imply broad or balanced diversification across asset classes leading to risk mitigation. The Index does not attempt to achieve a broad asset class diversification, and in some instances may have only equity exposure.

•The Index Has Limited History and May Perform in Unexpected Ways. The Index was launched on June 29, 2018. Because the Index is of recent origin with limited performance history, an investment linked to the Index may involve a greater risk than an investment linked to one or more indices with an established record of performance.

•An index fee of 0.50% per annum is deducted in the calculation of the Index. The index fee will place a drag on the performance of the Index, offsetting any appreciation of its portfolio, exacerbating any depreciation of its portfolio and causing the level of the Index to decline steadily if the value of its portfolio remains relatively constant. The Index will not participate in any appreciation of its portfolio unless it is sufficiently great to offset the negative effects of the index fee, and then only to the extent that the favorable performance of its portfolio is greater than the index fee (and subject to the volatility-targeting feature). As a result of this deduction, the level of the Index may decline even if its portfolio appreciates.

Please refer to the “Selected Risk Considerations” section beginning on page 6 of this underlying performance supplement, the “Selected Risk Considerations” section in the underlying supplement, the “Risk Factors” section in the accompanying product supplement and the “Selected Risk Considerations” section in the applicable pricing supplement for risks related to an investment in the securities, as applicable.

* The Average Allocation shown above reflects average daily exposure of the Index from March 20, 1998 to September 30, 2019. Past performance of the Index is no guide to future performance. The Average Allocation is based on both back-tested and actual historical Index performance information. For more information on the limitations of back-tested Index performance information, see “Limitations of Back-Tested Index Performance Information” below. Due to rounding, the numbers in the above table may not sum to 100%. The Average Allocation over the actual historical period from June 29, 2018 to September 30, 2019 was, respectively: 39%, 56%, 8%, and -3%. The Past Month Average Allocation is based on the actual allocation from August 30, 2019 to September 30, 2019.

Limitations of Back-Tested Index Performance Information

It is important to understand that back-tested index performance information is subject to significant limitations, in addition to the fact that past performance is never a guarantee of future performance. In particular:

• Credit Suisse International, the “Index Sponsor,” developed the rules of the Index with the benefit of hindsight—that is, with the benefit of being able to evaluate how the index rules would have caused the Index to perform had it existed during the back-tested period. The fact that the Index generally appreciated over a given back-tested period may not therefore be an accurate or reliable indication of any fundamental aspect of the Index methodology.

• The back-tested performance of the Index might look different if it covered a different historical period. The market conditions that existed during the historical period covered by the back-tested Index performance information are not necessarily representative of the market conditions that will exist in the future.

• Because the Component Indices were not published during the entire period for which the Index Sponsor has prepared back-tested Index performance information, the back-tested Index levels have been calculated by the Index Sponsor based in part on back-tested levels of the Component Indices that were prepared by their respective sponsor.

It is impossible to predict whether the Index will rise or fall. The actual future performance of the Index may bear no relation to the actual historical or back-tested levels of the Index.

Source: Credit Suisse, Bloomberg. The Index was launched on June 29, 2018. Back-tested data is shown from January 4, 1999 to June 29, 2018. Historical data is shown from June 29, 2018 to September 30, 2019. The shaded area indicates the period for which historical data is shown. Past performance of the Index is no guide to future performance. Performance is shown net of 0.50% per annum index fee embedded in the Index. Using back-tested methodology, Credit Suisse International, the “Index Calculation Agent,” has computed the closing level of the Index since March 20, 1998, with a hypothetical initial level of 100.

performance information, see “Limitations of Back-Tested Index Performance Information” above. In the Monthly and Annual Return Statistic Table, for 2019, “Year” refers to the YTD return.

“SPXT5UE” is the S&P 500^® Daily Risk Control 5% USD Excess Return Index. SPXT5UE was launched on September 10, 2009. Back-tested data for SPXT5UE is shown from January 4, 1999 to September 10, 2009. Historical data for SPXT5UE is shown from September 10, 2009 to September 30, 2019. Back-tested performance results have inherent limitations. For more information on the limitations of back-tested Index performance information, see “Limitations of Back-Tested Index Performance Information” above.

The relationship between the performance of the Index and the performance of SPXT5UE shown in the graph above is not an indication of how the performance of the Index may compare to the performance of SPXT5UE in the future. There is no guarantee that the Index will outperform SPXT5UE. By including performance information for SPXT5UE, no suggestion is made that SPXT5UE is the only alternative index to which the back-tested performance of the Index should be compared. You should independently evaluate an investment linked to the Index as compared to other investments available to you. In particular, you should note that, like the Index, SPXT5UE is an “excess return” index, which reflects the performance of a hypothetical investment made with borrowed funds and thus bears a hypothetical interest cost. The performance of excess return indices is less than the performance that could be achieved by a fully funded direct investment (i.e., an investment not made with borrowed funds).

As used in the table above, “Full Period” means the period from January 4, 1999 to September 30, 2019, including the period with back-tested performance results (including the Best Month) from January 4, 1999 to June 29, 2018.

As used in the table above, “Ann. Return” means the annualized return of the Index.

As used in the table above, “Ann. Volatility” means the annualized volatility of the Index.

As used in the table above, “Max Drawdown” means the greatest decline in the level of the Index from March 1998 to September 2019 as measured from the highest level of the Index to the lowest level of the Index, expressed as a percentage.

As used in the table above, “Sharpe Ratio” means the annualized return divided by the annualized volatility.

As used in the table above, “Return / Drawdown” means the annualized return of the Index divided by the absolute value of the Max Drawdown.

As used in the table above, “Best Month” means the highest monthly Index return from February 1999 to September 2019.

As used in the table above, “Worst Month” means the lowest monthly Index return from February 1999 to September 2019.

Index Asset Allocation and Realized Volatility Target

• Asset Allocation: The Index allocates (i) all of its exposure to the Equity Index during potential “lower volatility” periods and (ii) part of its exposure to the Equity Index and the remainder of its exposure to one or both Fixed Income Indices during potential “higher volatility” periods.

o When the historical realized volatility of the Credit Suisse US Equity Futures Index is greater than 5% (signaling “more risky” markets), the Index reduces its exposure to the Equity Index and allocates part of its portfolio to one or both Fixed Income Indices

o The greater the historical realized volatility of the Credit Suisse US Equity Futures Index, the less of the portfolio is allocated to the Equity Index and the more of the portfolio is allocated to one or both Fixed Income Indices.

• Risk Signal: Captures the presence of a downward trend in the performance of the 10Y Fixed Income Index.

o If the Risk Signal is off, the Index will allocate all of the fixed income exposure, if applicable, to the 10Y Fixed Income Index.

o The Risk Signal is turned on if the performance of the 10Y Fixed Income Index over the previous ten Index Calculation Days is lower than its historical moving average, indicating that the risk of future negative performance in ten-year U.S. Treasury note futures contracts is rising; in this scenario, the Index will allocate half of the fixed income exposure to the 10Y Fixed Income Index and the remaining half to the 2Y Fixed Income Index, which generally has a lower volatility than the 10Y Fixed Income Index.

• Realized Volatility Target: Index attempts to achieve a realized volatility target of 5% by varying its notional exposure to the portfolio of indices.

o The notional exposure to the portfolio on each Index Calculation Day will be set equal to the target volatility of 5% divided by the historical realized volatility of the portfolio calculated on such day, subject to a maximum notional exposure of 125%.

o If the realized volatility of the portfolio is less than 4.00%, the Index will not achieve its target volatility of 5% even with 125% exposure to the portfolio.

o An exposure of less than 100% would mean that the Index will participate in only a limited degree of the performance of the portfolio of the Component Indices, and the difference between 100% and that exposure will be hypothetically allocated to non-remunerating cash and will accrue no interest or other return.

Index Characteristics

• Objective: The Index is designed to provide exposure to a hypothetical “balanced” portfolio (consisting of the Equity Index and a momentum strategy-driven allocation of the Fixed Income Indices), while targeting a realized daily volatility of 5%

• Exposure: The Index’s hypothetical portfolio may, under certain circumstances, include both:

– equity exposure, in the form of notional E-mini S&P 500 futures contracts tracked by the Equity Index; and

– fixed income exposure, in the form of U.S. Treasury note futures contracts tracked by the Fixed Income Indices

Realized Volatility Target: The Index’s exposure to the portfolio is adjusted on each Index Calculation Day in an attempt to maintain its realized volatility target of 5%

Selected Risk Considerations

The following describes significant risks relating to the Index. We urge you to read the following information about these risks, together with the other information in the offering documents before investing in any securities linked to the Index. In particular, please review the “Selected Risk Considerations” section in the underlying supplement dated October 15, 2018 before investing in any securities linked to the Index.

Selected Risk Considerations Related to the Index

• The Index Does Not Attempt to Achieve a Broad or “Balanced” Asset Class Diversification. “Balanced” is not meant to imply broad or balanced diversification across asset classes leading to risk mitigation. The Index does not attempt to achieve a broad asset class diversification, and in some instances may have only equity exposure.

• The Index Has Limited History and May Perform in Unexpected Ways. The Index was launched on June 29, 2018. Because the Index is of recent origin with limited performance history, an investment linked to the Index may involve a greater risk than an investment linked to one or more indices with an established record of performance.

• An index fee of 0.50% per annum is deducted in the calculation of the Index. The index fee will place a drag on the performance of the Index, offsetting any appreciation of its portfolio, exacerbating any depreciation of its portfolio and causing the level of the Index to decline steadily if the value of its portfolio remains relatively constant. The Index will not participate in any appreciation of its portfolio unless it is sufficiently great to offset the negative effects of the index fee, and then only to the extent that the favorable performance of its portfolio is greater than the index fee (and subject to the volatility-targeting feature). As a result of this deduction, the level of the Index may decline even if its portfolio appreciates.

• The Index May Fail to Maintain Its Volatility Target and May Experience Large Declines as a Result. Because this exposure adjustment is backward-looking based on realized volatility over a prior period, because past volatility may not be predictive of future volatility and because there is a time lag between when volatility occurs and when the Index rebalances its portfolio, there may be a time lag before a sudden increase in the volatility of the portfolio of Component Indices is sufficiently reflected in the exposure to the portfolio of Component Indices to result in a meaningful reduction in realized volatility.

• The Volatility-Targeting Feature May Cause the Index to Perform Poorly in Temporary Market Crashes. The Index may not meaningfully reduce its exposure to the Index’s hypothetical portfolio until a crash has already occurred, and by the time the reduced exposure does take effect, the recovery may have already begun.

• The Volatility-Targeting Feature Could Cause the Index to Significantly Underperform Its Portfolio in Rising Equity Markets. The Index will have less than 100% exposure to the Index’s hypothetical portfolio at any time when realized volatility of the Index’s hypothetical portfolio is greater than the Index’s volatility target of 5%.

• The Index’s Volatility Target Is Arbitrary. Realized volatility is not the same as implied volatility, which is an estimation of future volatility and may better reflect market volatility expectation.

• The Credit Suisse US Balanced Index’s Decay Factors Are Arbitrary. The decay factors were chosen arbitrarily by Credit Suisse out of many decay factors that Credit Suisse could have selected, and may not be the optimal decay factors to use for the Index.

• Calculating the Preliminary Weight of the Equity Index in the Index’s Portfolio Based on the Arithmetic Average of the Short-Term and Long-Term Realized Volatilities of the Equity Index Is Arbitrary. This averaging of short-term realized volatility and long-term realized volatility is arbitrary and may dampen or heighten the calculated realized volatility of the Equity Index compared to other methods of calculating volatility such as implied volatility, which is an estimation of future volatility and may better reflect market volatility expectation.

• A Significant Portion of the Index May Be Hypothetically Allocated to Non-remunerating Cash, Which May Dampen Returns. At any time when the Index has less than 100% exposure to the Index’s hypothetical portfolio, a portion of the Index (corresponding to the difference between the exposure to the Index’s hypothetical portfolio and 100%) will be hypothetically allocated to non-remunerating cash and will not accrue any interest or other return.

• The Index Is Exposed to Risks Related to the Component Indices. The Index’s performance will be directly affected by the performance of the Component Indices and the risks related to the Component Indices.

• The Index’s Allocation Methodology May Not Be Successful If the Equity Index and the Fixed Income Indices Decline at the Same Time. If the equity component and the fixed income components tend to decline at the same time—in other words, if they prove to be positively correlated—the Index’s allocation

6

methodology will not be successful, and the Index may experience significant declines.

• The Index May Have Significant Exposure to the Fixed Income Indices, Which Have Limited Return Potential and Significant Downside Potential, Particularly in Times of Rising Interest Rates. The Fixed Income Indices offer only limited return potential, which in turn limits the return potential of the Credit Suisse US Balanced Index.

Selected Risk Considerations Related to the Component Indices

• Securities Linked to the Index Do Not Offer Direct Exposure to the S&P 500^® Index or U.S. Treasury Notes. The Equity Index tracks E-mini S&P 500 futures contracts, not the underlying S&P 500^® Index (nor the immediate value of its components). The Fixed Income Indices track the relevant U.S. Treasury note futures contracts, not the underlying U.S. Treasury notes (nor their spot price). Securities linked to the Index may underperform a similar investment linked to the spot prices or current levels of the underlying assets tracked by the futures contracts included in the Component Indices.

• The Level of the Component Indices May be Calculated and Published at Different Times than the Prices of the E-mini S&P 500 Futures Contracts or U.S. Treasury Note Futures Contracts. There could be market developments or other events that cause or exacerbate the difference between the price of the relevant E-mini S&P 500 futures contracts or U.S. Treasury note futures contracts and the level of the relevant Component Index.

General Risks Related to the Index and the Component Indices

The following risks relate to the Index and the Component Indices. The Index and the Component Indices are referred to below as the “indices”.

• Past Performance of the Indices Is No Guide to Future Performance and There Is No Assurance that the Strategies on Which the Indices are Based Will Be Successful. We cannot predict the future performance of the indices and there is no assurance that the strategy on which the indices is based will be successful in producing positive returns.

• There Can Be No Assurance that the Performance of the Indices over Time Will Approximate the Return of the Relevant Strategy or Any Other Strategy. The composition of the indices at any time is determined by

the allocation methodology, and is not actively managed by the relevant index sponsor. There can be no assurance that the performance of the indices over time will approximate the return of the relevant strategy or any other strategy.

• You Will Not Have Any Rights in Any U.S. Equity Futures Contracts or U.S. Treasury Note Futures Contracts Tracked by the Indices. The securities will be paid in cash, and you will have no right to receive any payment or delivery in respect of any E-mini S&P 500 futures contracts or U.S. Treasury note futures contracts.

• Owning the Securities Linked to the Index Is Not the Same as Directly Owning Any Futures Contracts or Securities Directly or Indirectly Tracked by the Indices. For example, as an investor in the securities, you will not have rights to receive dividends or other distributions or any other rights, including voting rights, with respect to any stocks included in the S&P 500^® Index tracked by the E-mini S&P 500 futures contracts, which are, in turn, tracked by the Equity Index.

• Suspension or Disruptions of Market Trading in Stocks or Futures Contracts May Adversely Affect the Value of the Securities. Stock markets and futures markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators, and government regulation and intervention. These circumstances could affect the level of the indices and the market value of the securities.

• We and Our Affiliates May Have Economic Interests Adverse to Those of the Holders of the Securities. Potential conflicts of interest may exist between our affiliates and you, including with respect to certain determinations and judgments that they must make in determining amounts due to you, either at maturity or upon early redemption of the securities or the composition or methodology of the indices.

• Adjustments to the Indices or to their Respective Components Could Adversely Affect the Securities. The relevant index sponsor can make methodological changes to the indices that could change the level of the indices at any time. Any action by the relevant index sponsor could adversely affect the performance of the indices and, therefore, the amount payable at maturity or repurchase and/or the market value of the securities.

• You Will Have No Rights Against the Entities with Discretion over the Indices or their Respective Components. As an owner of the securities, you will have no rights against the relevant index sponsor or the index calculation agent even though the amount you

7

receive at maturity or upon repurchase of your securities by Credit Suisse will depend on the level of the indices.

• The Indices Will Be Calculated Pursuant to a Set of Fixed Rules and Will Not Be Actively Managed. If the Indices Perform Poorly, the Relevant Index Sponsor

Will Not Change the Rules in an Attempt to Improve Performance. Unlike a mutual fund, which could be actively managed by the fund manager in an attempt to maximize returns in changing market conditions, the index rules will remain unchanged, even if those rules might prove to be ill-suited to future market conditions.
