3 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx 1. LIBOR Transition: Executive Summary

What does this document seek to do? This guide aims to give UBS clients an understanding of the LIBOR transition and highlights the practical considerations that should be taken into account. This communication is not sent to you in connection with any wealth management, corporate or institutional client or asset management relationship you may have with UBS. Summary Regulators have announced that the market should stop relying on LIBOR. Each of the Alternative Reference Rates (ARRs) for the five major currencies (USD, EUR, GBP, CHF, JPY) involved is at a different stage in terms of development and liquidity. Other currencies' alternative rates are also being developed but the initial focus has been on these five. The industry needs to understand, prepare and execute with respect to this market change. LIBOR is used as a in a multitude of products and links, for example between a derivative and an underlying asset, need to be considered in order to understand potential basis risk between LIBOR and the new ARR. In addition to migration of transactions, industry changes in discounting methodology are underway and changes in technology systems may be required. UBS aims to keep clients informed of these changes and is running an extensive internal change programme focussed on this transition. Note that and TIBOR are expected to remain in the medium term so industry focus is on the other rates. Practical considerations checklist • Understand what this change means for you: – Analyse the exposure you currently have to LIBOR and assess the potential financial impact – Ensure you know where you have transactions which you believe to be linked (see Forecasting Risk Section) – Review the fallback language in your Legal Documentation (see Forecasting Risk Section) • Review your readiness: – Evaluate whether you need to make any changes to your risk management systems – In addition, consider any operational processes you may need to update, for example ensuring all reference data sources are updated accordingly – Consider consolidating your LIBOR exposure to reduce the number of bi-lateral transitions required Key highlights Facts and Figures Discounting Risk Forecasting Risk • 5 ARRs have been identified • Discounting rate and interest paid • Updated ISDA Definitions and IBOR to replace the 5 LIBOR on collateral usually aligned Fallbacks Protocol were published currencies • CCPs have now switched 23 October 2020 and become • Each ARR is an discounting rates to ARRs and this effective on 25 January 2021 • The ARRs are backward is likely to be a key driver for • Differences in fallback methodology looking rates increased adoption of ARRs across different product types may • Adjustment methodology across the industry impact hedge effectiveness across agreed to address the • Any changes to the margin annex transactions believed to be linked differences (term and credit) for a derivative contract should • Evaluation of current contractual between LIBOR and ARRs reference the new ARR to replace fallback provisions may lead to existing cash margin rate increased bilateral discussion

What's next? When relevant, UBS will be contacting you in due course on the following topics: • Trades with UBS referencing LIBOR; • Contracts with UBS which reference a transitioning benchmark If you have any further questions, in the first instance please contact your sales representative. Alternatively, please get in touch via [email protected].

What is LIBOR? The London Interbank Offered Rate (LIBOR) is calculated from submissions by selected "panel" banks1 of the rates they either pay or would expect to pay to borrow from one another. LIBOR is a widely-used interest rate benchmark. Rates are determined daily by the LIBOR administrator, the ICE Benchmark Administration (IBA), for various currencies (USD, EUR, GBP, CHF, JPY) and tenors (Overnight, 1w, 1m, 2m, 3m, 6m and 12m).

Where is LIBOR used? According to IBA, LIBOR is used to determine periodic interest payments for many hundreds of trillions of notional of financial products globally, and is used for example in derivatives, bonds, structured products, securitised products and loans. What is happening to LIBOR and by when? Just over a decade ago, the market's perception of an increase in inter-bank credit risk inherently contained within LIBOR led to a widening of the basis between LIBOR and short-term interest rate futures. Financial institutions began to switch from using LIBOR to Overnight Index Swap rate (OIS) for discounting purposes, which was seen as being closer to a risk-free rate. At the same time, liquidity in the unsecured lending market, which underpins LIBOR, declined as banks became increasingly unwilling to lend to one another on an unsecured basis. The concern was that a lending rate, based on an increasingly less liquid market, was being used to reference many multiples of financial contracts. As a result, in 2017, the FCA announced that the market should transition to alternative reference rates based firmly on transactions, with panel bank support for current LIBOR to continue for a finite length of time. Despite market-driven transition challenges triggered by the COVID-19 pandemic, the FCA2 has stated that the transition away from LIBOR still needs to happen by the time LIBOR ceases to be available.

5 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx What has the response been to date? In response to these concerns on LIBOR, the Financial Stability Board's (FSB) review produced the basis for the 19 principles developed by the International Organization of Securities Commissions (IOSCO) 3. One of the key IOSCO principles was that a new "representative" benchmark reference rate should wherever possible be based on transactions and not expert judgement. Since the initial FCA statement in 20174, national working groups (see Forecasting Risk section) have been set up with the support of regulators and central banks with broad industry and market representation. These working groups have recommended alternative benchmarks for each of the LIBOR currencies. These alternatives are viewed as more robust benchmarks, compliant with IOSCO principles and are underpinned by larger volumes of observable transactions. It is expected that alternative reference rates (ARRs) with compounding in arrears will be a common feature of trades in the future. It is also expected that a term rate variation will also become available for SONIA and SOFR.

What are the main Alternative Reference Rates? Different jurisdictions have developed different methodologies for their new ARRs, and as illustrated in the timelines in the Appendix, these are all at different stages in terms of market liquidity and development. These ARRs are managed by different administrators, as outlined below.

Underlying Legacy transactions Reference Secured vs Rate Jurisdiction Working Group Rate Target ARR Unsecured Administrator Comments US Alternative USD LIBOR Secured Secured Federal Reserve There are Reference Rates Overnight Bank of ongoing Committee Financing Rate New York discussions (ARRC) (SOFR) regarding a credit sensitive index for the US market UK Working group GBP LIBOR Sterling Unsecured Bank of England on Sterling Risk- Overnight Index Free Reference Average (SONIA) Rates Euro Area Working Group EONIA1 Euro Short Term Unsecured European Reformed on Euro Risk- Rate (€STR) Central Bank EURIBOR is Free Rates expected to continue alongside €STR as a multiple rate approach.

7 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx How do these ARRs differ to LIBOR? The ARRs are structurally different from LIBOR and are not economic equivalents.

Components LIBOR ARRs Methodology Based on a waterfall methodology SOFR, SONIA, €STR, SARON and TONA are incorporating real transactions but also anchored in real transactions expert judgement Term Published for 7 maturities from overnight up Currently only available overnight, however note to one year that central banks and SIX have begun to publish indices to limit the amount of daily compounding calculations required for market participants Credit Risk Includes a risk adjustment to account for There is minimal credit spread adjustment as the Adjustment interbank credit spread and tenor ARRs are overnight rates and some ARRs are secured Rate The rate is set at the beginning of the period The rate is based on daily observations and is only known at the end of the period Settlement Paid at end of period There are a variety of conventions used in the Conventions calculation of cashflows dependent on backward looking rates: • Compounding of the overnight ARR over the payment period • Averaging of the overnight ARR over the payment period • Lockout • Backward Shift or Lookback Please see Appendix Overnight Index Swap Industry Definitions for further information on the above

These differences may mean market participants’ risk management systems might require enhancements to manage the different conventions which are used to calculate payments. Are these ARRs secured or unsecured? Some of the ARRs are secured rates, i.e. calculated from observed repurchase agreements (repos) collateralized by government bonds. This applies to SARON for CHF and SOFR for USD. The others are unsecured like LIBOR, i.e. based on unsecured borrowing with no actual underlying security. LIBOR differs from these unsecured ARRs as it is based not only on observed interbank borrowing transactions but also expert judgement. Will the ARRs have forward looking term structures? The ARRs developed to-date are overnight rates. There are ongoing efforts to develop forward looking term structures for the ARRs (except for SARON), the most advanced of these is in SONIA where there is sufficient depth in the ARR derivatives market in order to be able to calculate the rate. It is also expected that a SOFR term rate will be available for use by mid-2021.

What are ARR Compounded Index Rates? An alternative to forward-looking term structures is to provide the result of compounding a rate over a period (such as 30, 90, 180 days) and publishing these as indices. This action may assist some market participants to adopt these rates as it can limit the amount of daily compounding calculations required. Currently these indices are being published for SOFR by the Federal Reserve, SARON by the SIX Swiss Exchange & SONIA by the Bank of England.

8 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx What about the other IBOR Benchmark Rates? The initial focus has been on the five ARRs detailed above. In due course other alternative rates may be developed. See Appendix Other IBORs Benchmark Rates for selected examples of those currently under review.

Summary and Practical Considerations Below are some of the practical considerations clients should take into consideration for this LIBOR transition

Summary Practical Considerations include

• 5 ARRs have been identified to replace the 5 LIBOR • Evaluate whether you need to make any changes to currencies your risk management systems, specifically to ensure that you are able to trade, manage and settle • The ARRs are currently only overnight rates; term transactions referencing a backward looking rates may become available in some currencies in the compounded (or simple averaged) rate as opposed future to a forward looking term rate • The ARRs are generally published the following day • The methodology to calculate an adjustment to replace LIBOR with an ARR (to address the term and credit differences) has been agreed by ISDA If you have any further questions, in the first instance please contact your sales representative. Alternatively, please get in touch via [email protected].

9 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx 3. LIBOR Transition: Discounting Risk

What is discounting risk? Derivatives and other securities are often valued by discounting expected cashflows back to their present value using a discounting rate. The impact of a change of discounting rates on the valuation is referred to as Discounting Risk. Prior to the financial crisis, the rate used to discount cashflows in the derivatives market was LIBOR. Subsequently, many market participants adopted an approach that aligned the discounting rate used with the interest rate paid (cash margin rate) on the type(s) of collateral specified (known as Eligible Collateral) in the underlying Credit Support Annex (CSA). As such, any change to the discounting curve will not only change the Discounting Risk but also create a value transfer. Trillions of dollars’ worth of derivative contracts were either executed bilaterally between market participants under ISDAs (and if collateralized, with a CSA) or intermediated by Central Clearing Counterparties (CCPs). Many of these bilateral CSAs reference Effective (EFFR) or EONIA as the benchmark used to determine the interest paid on cash collateral posted. The CCPs have switched to using SOFR (from EFFR) to determine the margin interest rate (known as Price Aligned Interest5 (PAI) rate) for USD activity and €STR (from EONIA) for PAI for EUR activity. What changes have the CCPs made? London Clearing House (LCH) and Chicago Mercantile Exchange (CME) have adopted SOFR in place of EFFR and €STR in place of EONIA as the PAI rate and discounting rate for all USD and EUR discounted contracts held in the exchange. In order to minimize the resulting discounting basis risk, it is expected that some market participants will seek to renegotiate their bilateral CSAs referencing EFFR to SOFR following these switches. What are the implications for CSAs? To reflect the eligible collateral, the current overnight benchmarks for the major currencies are used to pay PAI. For example, EFFR is used as the PAI rate on the posting of USD cash collateral for the majority of bilateral CSAs. This rate is generally used as the discount rate to value the trade. Similarly, when it comes to posting of EUR cash collateral, EONIA is the PAI rate and the discount rate. European Money Markets Institute (EMMI) has announced that EONIA will be withdrawn at end of the 2021. CSAs referencing this rate should be updated before that date, for example, by replacing with €STR. For CSAs where non-cash collateral is used, e.g. government bonds, margin interest is not transferred between counterparties, therefore there is no need for any renegotiation to change the discounting rate used to value the trade. The discounting rate used to value the underlying derivative contracts of these CSAs is aligned to the funding rate for this collateral in the secured funding market. As an example, if US Treasuries are the only eligible collateral, this could currently mean that the discount rate used is EFFR for the CSA. This rate could change to SOFR once the secured funding market adopts SOFR as the funding rate instead of EFFR. CSA changes are beginning to accelerate post the switch from EONIA to €STR and from EFFR to SOFR by the CCPs in July and October 2020 respectively. The switch in discounting rates is a significant milestone for the LIBOR transition as it is expected that market participants will look to switch their discounting risk to match CCPs, thereby establishing hedging and re-hedging requirements in transactions referencing these ARRs: a key driver for adoption of ARRs as the market standard floating rate.

Why will these changes drive an increased Bilateral Negotiation of CSAs? In addition to the negotiations mandated by the Margin Requirements for Non-Centrally Cleared Derivatives regulations6 (with the first phase effective 1st September 2016 and final phase due 1st September 2021), CSA renegotiations driven by LIBOR transition are expected to be a major exercise. Given the majority of OTC contracts referencing LIBOR are cleared, there is an expectation that market participants may want to ensure that both current regulatory mandated and non-mandated bilateral CSAs are in line with CCP discounting and PAI. The industry has largely been through the transition from using LIBOR to overnight rates for discounting. The expectation is that the transition from current overnight rates (EONIA, EFFR) to ARRs (€STR, SOFR) will not be as

10 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx challenging as the transition from LIBOR to ARR for forecasting. Forecasting changes will be discussed in the next section. When will UBS be ready to open CSA negotiations? UBS has already commenced a number of CSA negotiations after the CCP transition dates to switch existing CSAs referencing EONIA to ESTR and EFFR to SOFR. Please contact your Sales representative if you wish to start this process and you have not been contacted yet. What is the impact on swaption contracts? The change in CCPs’ PAI for cleared swaps has had a corresponding impact on swaptions that reference the price of cleared swaps as the underlying instruments. UBS has evaluated the contractual terms of the relevant ISDA Supplements related to swaptions7 and is willing to discuss any changes to existing portfolios where required to incorporate latest market standards.

Summary and Practical Considerations Below are some of the practical considerations clients should take into account for this LIBOR transition

Summary Practical Considerations include • Discounting rate and interest paid on cash collateral • Review eligible collateral terms in your CSAs are usually aligned (specifically cash interest rate on margin) • Assess the economic impact of switching your interest rates • The switch in discounting rates by CCPs is likely to • Be mindful that basis risk may exist between your be a key driver for increased adoption of these new cleared and bilateral portfolios ARRs across the industry • Consider which CSAs you may need to prioritize renegotiation for in order to reduce this potential basis risk • Any changes to the margin annex for a derivative • A change to the cash margin rate in the agreement contract should reference the new ARR to replace will result in a change in margin interest flows and existing cash margin rate. potentially the discounting curve used for the underlying derivative portfolio • Consider there may be a value transfer with your bilateral counterpart for this change that will need to be agreed If you have any further questions, in the first instance please contact your sales representative.

11 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx 4. LIBOR Transition: Forecasting Risk

What is Forecasting Risk? LIBOR is widely applied as the floating interest rate benchmark referenced in a derivative (such as a swap floating leg), coupon on a bond or used to determine the interest rate on a loan. The valuation of such contracts or securities is driven by the change in the expected value of LIBOR—this is expressed as Forecasting Risk. Active LIBOR transition occurs when market participants switch out of LIBOR referenced contracts into ARR referenced contracts as market liquidity allows, rather than waiting until LIBOR ceases to exist. This activity would see ARR forecasting risk gradually replace LIBOR forecasting risk. The ARR forecasting curve is generally lower than the LIBOR equivalent.

What are the Fallback Provisions? For any contracts referencing LIBOR when it is discontinued, the parties will, in the absence of changes to the terms, have to rely on the contractual terms that exist to determine the post-cessation rate. The effectiveness and prevalence of these fallback provisions varies across products and markets. These provisions, depending on when drafted, may have the components listed in the following table. Market participants should review existing LIBOR- referencing financial contracts (that are expected to be held beyond the date by which LIBOR is no longer available) for provisions that determine the reference rate in the absence of LIBOR, or confirm the steps to be taken to frame an alternative. Various industry groups have provided fallback language for impacted financial products addressing permanent LIBOR cessation.

Term Definition Fallback Fallback language refers to the legal provisions in a contract that apply if the underlying Language reference rate (e.g. LIBOR) in the product is not published (whether on a temporary or permanent basis).

Fallback Rate The reference rate replacing LIBOR upon the Fallback Trigger Event. The updated ISDA Definitions specify ARRs as compounded in arrear settings as replacement rates for derivative contracts referencing LIBOR. However certain cash product contracts may contain no suitable language, resulting in the contracts falling back to the last LIBOR setting or the lenders' costs of funds. Spread As noted LIBOR is different to the ARR applicable in each jurisdiction and as part of ISDA fallback Adjustment methodology a fixed spread adjustment is applied to the ARR to account for differences in the construction of LIBOR and the ARR. Fallback Set of events relating to the original reference rate which may trigger the fallback to a new Trigger Event Reference Rate.

Clients should consider the economic and financial impact of the fallback provisions in their own contracts.

12 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx For example, the Federal Reserve Bank of New York's Alternative Reference Rate Committee has published language for cash products such as securitized products and loans. The Loan Market Association has also published fallback documentation for loans. ISDA published the updated ISDA Definitions on 23 October 2020 which become effective on 25 January 2021. The preference of the FCA8 is for market participants to pro-actively switch to new ARRs as soon as possible (as a primary approach), rather than to rely on fallback language (acting, in effect as a ‘seatbelt’). However, there are various aspects which may hinder this process; for example, liquidity in an ARR. What are some examples of differing fallback methods? There are different defined triggers and fallbacks for different products. In older bond documentation that did not foresee LIBOR cessation, for example, a common fallback is to use the last available published rate. Thus, in the event of LIBOR cessation, these securities would essentially become fixed rate products. In loans, a common ultimate fallback is to lenders' costs of funds. In a derivative, on the other hand, the alternative to LIBOR may be subject to calculation by agents (e.g. a dealer poll undertaken by a calculation agent). How will the LIBOR transition affect new contracts executed under the updated ISDA Definitions? The updated ISDA Definitions will become effective on 25 January 2021. All new derivative contracts executed after this date under the 2006 ISDA Definitions will contain the new fallback provisions. These updated Definitions include pre-defined ARR-based fallbacks for LIBOR and certain other IBORs and are triggered upon the occurrence of a pre-cessation or cessation announcement. How will the LIBOR transition affect the existing contracts? ISDA published the 2020 IBOR Fallbacks Supplement and Protocol on 23 October 20209. The new fallbacks will become effective for existing derivative contracts from 25 January 2021 where both counterparties have adhered to the Protocol or bilaterally implemented the Supplement prior to that date. Where one or both counterparties adhere to the Protocol after this date, the new fallback provision will become effective for contracts entered into before 25 January 2021 on the date the second counterparty adheres, or if the Supplement is implemented bilaterally from the date that is agreed. The ISDA Protocol has been drafted deliberately broad to cover transactions governed by ISDA Master Agreement or other forms of master agreement (e.g. Federation Bancaire Francaise, Swiss Master Agreement). If market participants choose not to sign up to the Protocol or do not adopt the provisions through a bilateral negotiation then the existing contracts will remain on the current fallback provisions as stipulated in the contract which when written probably did not envisage a permanent cessation of LIBOR. UBS encourages market participants to evaluate whether the Protocol is appropriate for their portfolios. ISDA's Benchmark Supplement10 also provides the option to implement a contractual process for existing contracts. However, both parties to the contract need to elect to implement the Supplement for existing contracts in order for this to take effect. It should be noted that even in ARRs where liquidity and volumes are most developed (e.g. SONIA), this is currently concentrated in linear derivatives such as swaps. For other types of products such as non-linear derivatives or cross currency derivatives there is currently little liquidity and volumes and market standards are still evolving. It should be noted that in these products, reliance on the ISDA Fallback Protocol to achieve transition may result in an outcome that is not aligned to the new market standards. Has UBS adhered to the 2020 IBOR Fallbacks Protocol? UBS has adhered to the ISDA 2020 IBOR Fallbacks Protocol across all of its main trading entities. What does this mean now that UBS has adhered to the IBOR 2020 Fallbacks Protocol? Where both bilateral parties in over-the-counter (OTC) derivatives adhere to the ISDA 2020 IBOR Fallbacks Protocol, relevant trades will have certainty of replacement rates upon a fallback trigger event.

13 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx IBOR fallbacks are triggered once LIBOR is deemed non-representative (also known as pre-cessation) or ceases to be published. Relevant trades are those traded before 25 January 2021 and are included within the list of documentation types within the ISDA 2020 IBOR Fallbacks Protocol. What is expected to happen to cleared contracts? CCPs have indicated they will look to apply the updated ISDA Definitions for all contracts (new contracts executed under updated Definitions as well as existing contracts)11. If CCP rulebooks are amended, will bilateral / manual amendments be required to ETD agreements with UBS? There is no requirement to repaper ETD Clearing Agreements as UBS mirrored relevant CCP rulebook provisions in its ETD agreements. There may be some commercial changes around the benchmarks used to calculate interest paid/received on margin balances but this resides outside of the ETD agreement and is part of the commission schedule. These changes would be discussed and agreed with clients ahead of implementation. How will the LIBOR transition affect products other than OTC derivatives? Although the ISDA Protocol covers some non-derivative agreement types, products such as loans and bonds sit outside of its scope. The industry is still working on approaches to improve the fallback language for such products. How could hedge effectiveness across asset classes via linked transactions be affected by the LIBOR transition? Differences in fallback methodology across different product types have added more complexity to the transition for linked transactions. For example, a swap hedging the LIBOR component of a bond or loan may continue to be an effective hedge upon the triggering of differing fallback methodologies. Market participants may need to review any linked or hedged transactions and evaluate contractual fallbacks in place. What is the ISDA LIBOR to ARR adjustment? ISDA has consulted with the industry to determine a market consensus on the methodology used to calculate the adjustment spread to address the term and credit differences between LIBOR and the ARR and other factors such as liquidity and fluctuations in supply and demand. These consultations12 have established that market participants prefer to use the compounded setting in arrears rate to address differences in tenor between IBORs and overnight ARRs, and the historical median spread over a five-year lookback period approach. Note that Bloomberg has begun to publish these LIBOR fallback rates as per ISDA's agreed methodology as of 21 July 2020. The real time data can be accessed via FBAK on Bloomberg Terminals, and is publicly available, with a delay, on the Bloomberg website13. Upon an announcement on permanent or pre-cessation, the spread adjustment under the ISDA Fallbacks for LIBOR will be fixed. What are the ARRC's recommended best practices? ARRC published its best practices14 for completing transition from LIBOR to provide date-based guidance, including when no new LIBOR activity should be conducted. Please see Appendix ARRC recommended best practices for further information.

14 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx What is Pre-Cessation?

Cessation and Pre-Cessation Definitions Terms Definition Cessation Event Event whereby a reference rate is discontinued or unavailable permanently, triggering Fallback. A typical LIBOR cessation event would occur if there were no longer sufficient panel banks contributing to calculation of LIBOR Pre-Cessation Event An event which impacts the reference rate but does not prevent its publication. With respect to LIBOR, such an event could be where the FCA deems LIBOR unrepresentative per Benchmarks Regulation and prohibit its use in contracts.

ARRC15 recommended the industry to include Pre-Cessation as a Fallback Trigger event in the Fallback Provisions for any new cash products referencing LIBOR. The updated ISDA Definitions include both pre-cessation fallbacks (based on a 'non-representativeness' determination) and permanent cessation fallbacks. This will apply to all new derivatives referencing LIBOR that incorporate the amended 2006 ISDA Definitions traded after the effective date 25 January 2021. For Legacy trades (i.e. those transacted prior to the effective date of the updated Definitions which is 25 January 2021) market participants are expected to evaluate whether the updated Definitions which are appropriate and incorporate via adherence to the ISDA 2020 Fallbacks Protocol. What is 'Synthetic LIBOR'? On 23 June 2020 HM Treasury16 announced that it intends to bring forward legislation to amend the Benchmarks Regulation (BMR) to give the FCA new and enhanced powers. These could help manage and direct an orderly wind-down of critical benchmarks such as LIBOR. The proposed changes will create a possible way of reducing disruption by enabling continued publication of a LIBOR rate using different and more robust methodology and inputs. The legislation would allow the FCA to direct a change to the methodology, if doing so would better protect consumers and the integrity of the market than cessation of the rate. By acting via the administrator, certain LIBOR currency and tenor settings (including the screen rates) are expected to be preserved and remain in place under the new methodology for an extended period. We will refer to this continued publication of LIBOR under a different methodology as 'Synthetic LIBOR’. The FCA’s Statement on 18 November 2020 provided a clearer indication of which LIBORs may be able to be continue publication in the form of Synthetic LIBOR, albeit for specific use cases. CHF and EUR LIBOR are unlikely to meet requirements under the new methodology, while GBP LIBOR is likely to continue; JPY and USD LIBOR are yet to be determined. The FCA has also indicated that they envisage calculating GBP Synthetic LIBOR based on a forward looking SONIA Term Rate plus a fixed adjustment spread under the same ISDA methodology. What are the implications of 'Synthetic LIBOR' on Transition? Regulators still expect the same focus and urgency from market participants to transition from LIBOR by primarily actively switching from LIBOR contracts into ARR contracts or failing that, to insert robust and workable fallback. These new and enhanced powers may allow the continued publication of LIBOR (including the screen rates) with a more robust methodology and inputs. It is expected to be based on forward looking term ARRs plus a fixed adjustment spread per ISDA methodology. Synthetic LIBOR is also expected to be restricted by the FCA17 for use by UK supervised entities to some or all tough legacy contracts. Tough Legacy contracts are contracts that have no or inappropriate/unviable alternatives and no realistic ability to be renegotiated or amended. A policy of statement is expected from the FCA to define which tough legacy contracts could use Synthetic LIBOR following its consultation in Q2 2021.

15 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx What are the latest expected publication dates for LIBOR? Subject to the outcomes of its consultations, ICE Benchmark Administration (IBA) announced in November 2020 that they will cease publication of GBP, CHF, EUR and JPY LIBOR (all tenors) and USD LIBOR (1-Week and 2-Month) at the end of 2021. However, other USD LIBOR tenors will continue to be published by IBA until end-June 2023. The implications of this is that some bifurcation of cessation timelines and transition approaches across LIBOR currencies is now expected, including: • USD LIBOR: the expected final publication of USD LIBOR Tenors (except 1W and 2M) will be 30 June 2023. Firms are expected to cease entering into new contracts using USD LIBOR as soon as practical or at the latest by 31 December 2021. Existing contracts that have not been transitioned upon cessation may be impacted by potential legislation underway in the US. To-date, the FCA has not indicated any plan for Synthetic USD LIBOR. • GBP LIBOR: a pre-cessation announcement is likely in 2021 with the effective date on or shortly after 31 December 2021. A Statement from the FCA indicated that GBP LIBOR is likely to continue publication under an amended methodology of a SONIA term rate + fixed spread (defined as Synthetic GBP LIBOR) with expected restrictions upon its usage. • CHF, EUR LIBOR: the expected final publication is 31 December 2021. Continued publication is unlikely. • JPY LIBOR: the expected final publication is 31 December 2021. Continued publication under an amended methodology is yet to be decided. IBA will close the consultation for feedback by 25 January 2021. To-date, there has been no decision on whether other currencies linked to USD LIBOR (e.g. SOR) would update their timelines to align with USD LIBOR. A joint statement was issued by the Federal Reserve, Office of the Comptroller of the Currency (OCC) and the Federal Deposit Insurance Corporation (FDIC) on 30 November, stating that firms should not enter into new transactions referencing USD LIBOR after 31 December 2021. Additionally, in light of potential safety and soundness concerns around new USD LIBOR contracts, they would examine firms' current practices. Why is the Transition challenging for certain products? Certain contracts which reference LIBOR (including bonds, structured products, securitized products, loans and a subset of existing contracts) may have characteristics that impede smooth transition such as product mechanics for material amendments, non-linearity, illiquidity or because they act as hedges to products with different fallback methods. Non-Protocol Covered agreements and confirmations may need to be reviewed to determine an approach. Generally, this approach is likely to involve market participants being requested to sign documentation agreeing to incorporate robust fallback language to allow the transition to the relevant replacement rate. Why might these Forecasting Risk changes drive increased bilateral/ multilateral negotiation? Due to the increased complexity introduced by the differences between asset class fallbacks and product amendment mechanics, the industry is expected to need to perform a significant review of contractual documentation before agreeing to change terms on their existing trades. Amendments to existing trades will be a challenging exercise if market participants have to amend a significant volume of trades across different products on a bilateral or multilateral basis. What are the main drivers that may determine the impact on Forecasting Risk? The level of impact on value and Forecasting Risk will be driven by but not limited to the following: • The specific legacy reference rate • Whether term rates become available • The specific fallback trigger provisions in existing contract(s) • Fallback rate to include an adjustment required to reflect the credit and term differences agreed by industry groups • The maturity of the contract(s) • The date when changes are expected to happen • The type of product as there are potentially differing industry solutions There is no industry consensus on how the change in the value of contracts between parties will be handled.

Summary and Practical Considerations Clients should study existing contracts that reference LIBOR and consider future trading and risk management requirements and seek professional advice (if applicable) on the economic, legal, and operational implications. Clients may also consider their specific capital, accounting, and tax consequences of LIBOR transition. Below are some of the practical considerations clients should take into consideration for this LIBOR transition.

Summary Practical Considerations include

• Increased complexity may be introduced by the • You should perform a review of contractual differences between asset class fallbacks documentation before agreeing to change terms on existing trades keeping in mind that current fallback provisions may create, upon cessation, a fallback to a rate inconsistent with the economics of the original deal • Acknowledge that in any new fallback provisions that specify an ARR to replace LIBOR, there may be an adjustment (to address the term and credit differences) • Updated ISDA Definitions and ISDA 2020 IBOR • New OTC derivative contracts executed under ISDA Fallbacks Protocol published 23 October 2020 Definitions will incorporate robust fallbacks effective from 25 January 2021. For legacy OTC derivative

trades, you should consider and determine whether to adhere to the ISDA 2020 IBOR Fallbacks Protocol to incorporate robust fallbacks • Differences in fallback methodology across different • Identify all transactions which you believe to be product types may impact hedge effectiveness across linked and evaluate contractual fallbacks in place in transactions which you believe to be linked order to determine an approach to mitigate potential differences in fallback methodology across these transactions • Evaluation of current contractual fallback provisions • You may be requested to sign documentation may lead to increased bilateral discussion agreeing to the transition to the relevant replacement rate or adopt the ISDA Benchmark Supplement. However the latter is an alternative path that does not provide certainty of economic outcome • Stay up to date with the industry announcements • Categorize your in-scope population of trades in related to cessation or pre-cessation announcement relation to possible transition activities. Note any dates as these will fix fallback rates spreads.

Discussions are ongoing on a conventions switch from LIBOR to SONIA in the derivative markets, and this includes non- linear derivatives, cross currency swaps and futures. It is acknowledged that non-linear and cross-currency RFR markets currently remain nascent, and that there will be further developments on the approach for transition of legacy non-linear derivatives during 2020.

24 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx Other IBORs Benchmark Rates The other IBOR benchmark rates are detailed in the below table.

Jurisdiction Reference Rate Administrator Commentary Euro Area EURIBOR EMMI The most widely used benchmark of the other IBORs; the European Commission has expressed confidence in EURIBOR for the medium term. A new hybrid methodology is in the process of being implemented. The ECB RFR WG proposed roadmap18 (published in late 2019) suggests that 2020 work focus are on:

i) EONIA transition to ESTR, particularly on building liquidity for ESTR and the CCP discounting switch that occurred on Monday 27 July, and ii) Development of ESTR-based fallbacks for EURIBOR, however the final recommendation has been deferred to Q1 2021 due to COVID 19 impact per the May ECB RFR WG minute.

A list of key milestones and publications can be found from the ECB RFR WG website19 On 23 November 2020, the ECB Working Group on Euro Risk- Free Rates published two public consultations on fallback rates to EURIBOR, calling for views on: 1. Fallback rates based on €STR and spread adjustment methodologies in order to produce the most suitable EURIBOR fallback measures per asset class 2. Potential events that could trigger such fallback measures.20 Japan TIBOR JBA In August 2020 the BoJ Cross-Industry Committee on Japanese Yen published its latest consultation21 on JPY interest rate benchmarks, recommending fallback replacement rates and spread adjustments for legacy cash products referencing JPY LIBOR. The consultation paper included a draft transition roadmap, setting out key transition targets: • start negotiating amongst contracting parties from 3Q 2020 • developing loans and bonds systems and operations on compounded ARRs in arrears by end 1Q 2021 • publication of daily prototype rate from 4Q2020 and forward looking term rate by mid-2021 • ceasing new LIBOR loans and bonds by end 2Q 2021, and significant reduction of LIBOR stock by end 3Q 2021.

25 SH-Presentations Client Guide (UBS Format) UNAPPROVED v6.0.10.docx Jurisdiction Reference Rate Administrator Commentary Australia BBSW ASX BBSW will likely remain as a benchmark following extensive and ongoing work by its administrator, ASX, to strengthen its methodology. The interbank overnight Cash Rate (also referred to as AONIA) is the alternative rate and may be more appropriate in the future as closely aligned to the features of other ARRs.

ISDA have included AONIA as the fallback rate for BBSW within the recently published ISDA 2020 IBOR Fallbacks Protocol.

The RBA will make it a prerequisite that fallback provisions be introduced for new securities referencing BBSW before the securities can be eligible for RBA's market operations. FRNs provided by banks, securitization trusts and governments will be affected by this. After consultation with the industry, the timing and specifics of the introduction of this requirement will be determined.

China SHIBOR NIFC Shanghai No significant notices on cessation or change to the benchmark noted. Hong Kong HIBOR TMA Hong Kong has adopted a multiple-rate approach, whereby HIBOR and HONIA will co-exist and market participants are free to choose between them.

A circular on interest rate benchmark reform was released by HKMA in July 2020, setting out key milestones for Authorised Institutions: • Products should be available from 1 January 2021 referencing the ARRs to LIBOR • All newly issued LIBOR-linked contacts maturing after 2021 from 1 January 2021 should contain adequate fallback provisions • Issuance of new LIBOR-linked products maturing after 2021 should cease by 30 June 202122 Singapore SIBOR ABS Transition from SIBOR to SORA is recommended as part of a SORA centered approach.

On 29 July 2020, the ABS, SFEMC and the SC-STS published a joint industry report with the recommendation of discontinuation of SIBOR, and shifting to the use of SORA as the primary interest rate benchmark for SGD markets.23

Work is ongoing to have STIBOR approved under the BMR. In April 2020 the Swedish Bankers’ Association has transferred the administration of STIBOR to Swedish Financial Benchmark Facility (SFBF).25 New Zealand BKBM NZFMA The NZFMA has selected the OCR to act as the ARR for BKBM. The new ARR will be calculated independently to the BKBM fallback benchmark rate, with the NZFMA currently developing a term structure methodology. BKBM will likely continue as a benchmark in NZD.26 Canada CDOR RBSL Canada currently operates with both CDOR and CORRA co- existing. It is expected however, that over time CORRA will become the predominant Canadian interest-rate benchmark, especially for derivatives and floating-rate notes.
