Introduction and basis for preparation

Scope and location of Basel III Pillar 3 disclosures

The Basel III capital adequacy framework consists of three complementary pillars. Pillar 1 provides a framework for measuring minimum capital requirements for the credit, market, operational and non-counterparty-related risks faced by banks. Pillar 2 addresses the principles of the supervisory review process, emphasizing the need for a qualitative approach to supervising banks. Pillar 3 requires banks to publish a range of disclosures, mainly covering risk, capital, leverage, liquidity and remuneration.

This report provides Pillar 3 disclosures for UBS Group AG and UBS AG on a consolidated basis, as well as prudential key figures and regulatory information for our significant regulated subsidiaries and sub-groups. Information provided in our Annual Report 2018 or other publications may also serve to address Pillar 3 disclosure requirements. Where this is the case, a reference has been provided in this report to the UBS publication where the information can be located. These Pillar 3 disclosures are supplemented by specific additional requirements of the Swiss Financial Market Supervisory Authority (FINMA) and voluntary disclosures on our part.

As UBS is considered a systemically relevant bank (SRB) under Swiss banking law, UBS Group AG and UBS AG are required to comply with regulations based on the Basel III framework as applicable to Swiss SRBs on a consolidated basis. Capital and other regulatory information as of 31 December 2018 for UBS Group AG consolidated is provided in the “Capital management” section of our Annual Report 2018 .

Capital and other regulatory information as of 31 December 2018 for UBS AG consolidated is provided in the UBS Group AG and UBS AG Annual Report 2018, and additionally, in the “KM1: Key metrics“ table for UBS AG consolidated on page 110 in this report. We are also required to disclose certain regulatory information for UBS AG standalone, UBS Switzerland AG standalone and UBS Limited standalone, as well as UBS Americas Holding LLC consolidated. This information is provided in the “Significant regulated subsidiaries and sub-groups” sections of this report.

Local regulators may also require publication of Pillar 3 information at a subsidiary or sub-group level. Where applicable, these local disclosures are provided under “Holding company and significant regulated subsidiaries and sub-groups” at www.ubs.com/investors .

Refer to the overview on our external reporting approach under “Annual Reporting“ at www.ubs.com/investors . Our quarterly reports are available under “Quarterly Reporting“.

Significant regulatory and disclosure requirements and changes effective in 2018

Significant BCBS and FINMA capital adequacy, liquidity and funding and related disclosure requirements

This Pillar 3 report has been prepared in accordance with FINMA Pillar 3 disclosure requirements (FINMA circular 2016 / 01 “Disclosure – banks”) issued on 16 July 2018, the underlying Basel Committee on Banking Supervision (BCBS) guidance “Revised Pillar 3 disclosure requirements” issued in January 2015, the “Frequently asked questions on the revised Pillar 3 disclosure requirements” issued in August 2016, and the “Pillar 3 disclosure requirements – consolidated and enhanced framework” issued in March 2017.

The legal entities UBS AG and UBS Switzerland AG are subject to standalone capital adequacy, liquidity and funding, and disclosure requirements defined by FINMA. This information is provided in the “Significant regulated subsidiaries and sub-groups” section of this report.

Changes to Pillar 1 requirements

Revised Basel III securitization framework

Effective 1 January 2018, we became subject to the revised Basel III securitization framework for securitization exposures in the banking book, which had an immaterial effect on our risk-weighted assets (RWA). Related changes to Pillar 3 disclosure requirements are described on the next page.

Revised methodology for structured margin lending transactions

We revised the methodology applied for structured margin lending transactions, as agreed with FINMA. This revision resulted in an increase of USD 3.3 billion in counterparty credit risk RWA in the third quarter of 2018.

Changes to presentation currency affecting Pillar 1 and Pillar 3 disclosures

In October 2018, the presentation currency of UBS Group AG’s and UBS AG’s consolidated and standalone financial statements changed from Swiss francs to US dollars. In line with these accounting changes, the presentation currency of UBS Group AG’s consolidated and UBS AG’s consolidated and standalone Pillar 3 disclosures in this report have changed from Swiss francs to US dollars. Prior periods were translated to US dollars at the respective spot rates prevailing for the relevant periods unless specified otherwise. We have restated the composition of cash collaterals in domestic currency and other currencies in “CCR5: Composition of collateral for CCR exposure” table as if the US dollar was our domestic currency for all periods.

We continue to report Pillar 1 and other regulatory submissions to FINMA and to the Swiss National Bank in Swiss francs.

® Refer to the “Significant accounting and financial reporting changes” section in our Annual Report 2018 for more information

Changes to accounting affecting Pillar 1 and/or Pillar 3 disclosure requirements

Effective 1 January 2018, we adopted IFRS 9, Financial Instruments. The implementation of IFRS 9 resulted in a reduction of Basel III common equity tier 1 (CET1) capital as of 1 January 2018 by approximately USD 0.3 billion and an increase of RWA by approximately USD 0.7 billion.

The related FINMA guidance for the regulatory treatment of accounting provisions was issued on 16 July 2018, with an effective date of 1 January 2019. Effective from 31 December 2018, UBS opted to phase in the effects from IFRS 9 ECL on CET1 capital, if any, over a five-year transitional period.

In addition, the implementation of IFRS 9 resulted in the following structural and calculation changes to our semi-annual and annual Pillar 3 disclosures, which are also outlined in footnotes or narrative text for the relevant tables:

(a) Allowances and impairments included in “CR1: Credit quality of assets,” “CRB: Breakdown of impaired exposures by industry,” “CRB: Impaired financial instruments by geographical region,” “CRB: Breakdown of restructured exposures between impaired and non-impaired,” and provisions included in “CR6: IRB – Credit risk exposures by portfolio and PD range” as of 30 June 2018 and 31 December 2018 reflect ECL allowances and provisions related to stages 1–3. Comparative numbers as of 31 December 2017 are based on the incurred loss model of IAS 39, Financial Instruments: Recognition and Measurement, and are largely comparable to the IFRS 9 stage 3 allowances and provisions.

(b) The definitions of the FINMA-defined Pillar 3 credit risk exposure categories “Loans” and “Debt securities” have been updated to reflect the new IFRS balance sheet structure under IFRS 9.

(c) RWA included in “CR10: IRB (equities under the simple risk weight method)” increased primarily due to the transition effect of IFRS 9, as a result of the reclassification of equity instruments from the IAS 39 category financial assets available for sale to the IFRS 9 category fair value through profit or loss, as unrealized gains on such instruments (previously deducted from Basel III CET1 capital) were added back to the exposure at default for the purpose of the RWA calculation.

(d) The templates “LI1: Differences between accounting and regulatory scopes of consolidation and mapping of financial statement categories with regulatory risk categories,” “CRB: Breakdown of exposures by industry,” “CRB: Breakdown of exposures by geographical area” and “CRB: Breakdown of exposures by residual maturity” have been aligned with the IFRS 9-related changes to our balance sheet presentation.

Changes to Pillar 3 disclosure requirements

– In the first quarter of 2018, the “OV1: Overview of RWA” table was enhanced to adopt the revised template introduced with the second phase of revised Pillar 3 disclosure requirements to reflect changes as a result of the aforementioned revised securitization framework.

– The tables “SEC3: Securitization exposures in the banking book and associated regulatory capital requirements – bank acting as originator or as sponsor” and “SEC4: Securitization exposures in the banking book and associated regulatory capital requirements – bank acting as investor” have been modified to reflect changes in line with the revised securitization framework.

– In March 2017, the BCBS issued the “Pillar 3 disclosure requirements – consolidated and enhanced framework,” which represents the second phase of the BCBS review of the Pillar 3 disclosure framework and builds on the revisions to the Pillar 3 disclosure requirements published in January 2015. On 16 July 2018, FINMA issued a revised Circular 2016 / 01 “Disclosure – banks” including the aforementioned second phase revisions, which requires banks to gradually implement the requirements from 31 December 2018 onward.

– We either disclosed or amended the following tables and / or narratives for the first time in or alongside this report:

– KM1: Key metrics

– PV1: Prudential valuation adjustments

– CC1: Composition of regulatory capital, replacing the “Composition of capital” table

– CCyB1: Geographical distribution of credit exposures used in the countercyclical buffer

– LIQA: Liquidity risk management

– CCA: Main features of regulatory capital and other TLAC instruments.

Significant BCBS and FINMA requirements to be adopted in 2019 or later

Final guidance

Revised capital adequacy ordinance (CAO) and banking ordinance (BO)

The revised CAO and BO became effective from 1 January 2019, and included guidance on the treatment of bail-in bonds from other international SRBs held by UBS, amendments to gone concern requirements and the treatment of material group entities, subject to the regulatory scope of consolidation, all of which are not expected to have a material effect on UBS.

Revised FINMA circulars on credit risk and leverage ratio

On 16 July 2018, FINMA issued revised circulars mainly on:

– leverage ratio (FINMA Circular 2015 / 03 “Leverage ratio – banks”) to allow early adoption before 1 January 2020 of modified standardized approach for counterparty credit risk (SA-CCR) rules in line with the BCBS Basel III finalization of the capital framework issued in December 2017;

– credit risk (FINMA Circular 2017 / 07 “Credit risk – banks”) to incorporate frequently asked questions on the standardized approach for SA-CCR that will be effective from 1 July 2019 for banks applying SA-CCR, with early adoption permitted. In addition, other amendments related to the eligibility of short-term debt instruments as financial collateral and the recognition of unrestricted life insurance policies as guarantees, which have become effective from 1 January 2019, were also included in the same circular.

Basel III finalization and adjustments to market risk framework

In December 2017, the BCBS finalized the Basel III capital framework, which will take effect from 1 January 2022, with a five-year phase-in period for the aggregate output floor. The most significant changes include:

– placing floors on certain model inputs under the IRB approach to calculate credit risk RWA;

– requiring the use of standardized approaches for calculation of credit valuation adjustment and for operational risk RWA;

– placing an aggregate output floor on the Group RWA equal to 72.5% of the RWA calculated using a revised standardized approach; and

– revising the leverage ratio denominator (LRD) calculation and introducing a leverage ratio surcharge for global systematically important banks.

In January 2019, BCBS also issued final revisions of the market risk framework (Fundamental Review of the Trading Book (FRTB)). The revisions include adjustments to the risk sensitivity of the standardized approach, the calibration of certain elements of the framework and adjustments of the internal models approach. This revised standard comes into effect on 1 January 2022 along with the overall revised Basel III capital framework.

Regulatory interpretation is ongoing and the implementation of the Basel III capital framework and the market risk framework into national law has not yet been announced.

Pillar 3 disclosure requirements

In March 2017, the BCBS issued the “Pillar 3 disclosure requirements – consolidated and enhanced framework.”

In July 2018, FINMA issued the revised circular 2016 / 01 “Disclosure – banks”, which requires banks to gradually implement the requirements from 31 December 2018 onward. Refer to the previous page for requirements implemented as of 31 December 2018.

The following disclosure will be adopted or revised in first half of 2019, according to the applicable effective dates:

– KM2: Key metrics – TLAC requirements (at resolution group level) as of 31 March 2019

– CR1: Credit quality of assets as of 30 June 2019

– TLAC1: TLAC composition for global systemically relevant banks (G-SIBs) at resolution group level as of 30 June 2019

– TLAC2: Material subgroup entity – creditor ranking at legal entity level as of 30 June 2019

– TLAC3: Resolution entity – creditor ranking at legal entity level as of 30 June 2019

– IRRBBA: Interest rate risk in the banking book (IRRBB) – risk management objective and policies – qualitative requirements as of 30 June 2019

– IRRBBA1: IRRBB – risk management objective and policies – quantitative requirements as of 30 June 2019

– IRRBB1: Quantitative information on IRRBB as of 30 June 2019

In December 2018, the BCBS published its updated Pillar 3 disclosure requirements, completing revisions to the disclosure framework started earlier. This revision reflects the final Basel III standards issued in December 2017, and sets out new disclosure requirements on asset encumbrance and, if required by national supervisors at the jurisdictional level, on capital distribution constraints. The implementation deadline for the disclosure requirements related to Basel III is 1 January 2022. The effective date for the disclosure requirements for asset encumbrance, capital distribution constraints and the prudential treatment of problem assets is the end of 2020.

Significant BCBS and FINMA consultation papers

Leverage ratio treatment of client cleared derivatives

In October 2018, the BCBS issued a consultation paper to seek public feedback by mid-January 2019 on whether or not the leverage ratio’s treatment of client cleared derivatives under the Basel III finalization of the capital framework issued in December 2017 should be amended to allow cash and non-cash initial margin received from a client to offset the potential future exposure, or to align existing treatment with the standardized approach for measuring counterparty credit risk exposures. In line with the current exposure measure applied in the current leverage ratio calculation, the leverage ratio’s treatment under the Basel III finalization of the capital framework issued in December 2017 only allows variation margin in the form of cash to offset replacement cost.

Revisions to leverage ratio disclosure requirements

In response to particular concerns regarding "window-dressing", BCBS issued a consultation paper in December 2018 on mandating the additional disclosure of leverage ratio exposure amounts of securities financing transactions, of derivative replacement costs and of central bank reserves, all to be calculated using daily averages over the reporting quarter. Comments on this consultation paper are due by mid-March 2019.

Frequency and comparability of Pillar 3 disclosures

FINMA has specified the reporting frequency for each disclosure, as outlined in the table below. We generally provide quantitative comparative information as of 31 December 2017 for all disclosures, except reconciliations. Depending on the FINMA-specified disclosure frequency, we provide additional quantitative prior-period information:

– For quarterly disclosures on movements related to RWA for credit risk, counterparty credit risk and market risk, we provide additional comparative information for the third, second and first quarters of 2018.

– For the overview of RWA, we provide additional comparative information as of 30 September 2018, 30 June 2018 and 31 March 2018.

– For all other quarterly disclosures, we provide additional comparative information as of 30 September 2018 only.

– For semiannual disclosures, we provide additional comparative information as of 30 June 2018.

Where required, movement commentary is aligned with the corresponding disclosure frequency required by FINMA and always refers to the latest comparative period. Throughout this report, signposts are displayed at the beginning of a section, table or chart – Annual | Semiannual | Quarterly | – indicating whether the disclosure is provided quarterly, semiannually or annually. A triangle symbol – p p p – indicates the end of the signpost.

Format of Pillar 3 disclosures

As defined by FINMA, certain Pillar 3 disclosures follow a fixed format, whereas other disclosures are flexible and may be modified to a certain degree to present the most relevant information. Pillar 3 requirements are presented under the relevant FINMA table / template reference (e.g., OVA, OV1, LI1, etc.). Pillar 3 disclosures may also include row labeling (1, 2, 3, etc.) as prescribed by FINMA. Naming conventions used in our Pillar 3 disclosures are based on the FINMA guidance and may not reflect UBS naming conventions.

The FINMA-defined asset classes used within this Pillar 3 report are as follows:

– Central governments and central banks, consisting of exposures relating to governments at the level of the nation state and their central banks. The European Union is also treated as a central government.

– Banks and securities dealers, consisting of exposures to legal entities holding a banking license and securities firms subject to adequate supervisory and regulatory arrangements, including risk-based capital requirements. Securities firms can only be assigned to this asset class if they are subject to a supervision equivalent to that of banks.

– Public sector entities, multilateral development banks, consisting of exposures to institutions established on the basis of public law in different forms, such as administrative entities or public companies as well as regional governments, the BCBS, the International Monetary Fund, the European Central Bank and eligible multilateral development banks recognized by FINMA.

– Corporates: specialized lending, consisting of exposures relating to income-producing real estate and high-volatility commercial real estate, commodities finance, project finance and object finance.

– Corporates: other lending, consisting of all exposures to corporates that are not specialized lending. This asset class includes private commercial entities such as corporations, partnerships or proprietorships, insurance companies and funds (including managed funds).

– Retail: residential mortgages, consisting of residential mortgages, regardless of exposure size, if the owner occupies or rents out the mortgaged property.

– Retail: qualifying revolving retail exposures, consisting of unsecured and revolving credits to individuals that exhibit appropriate loss characteristics relating to credit card relationships at UBS.

– Retail: other, consisting primarily of Lombard lending that represents loans made against the pledge of eligible marketable securities or cash, as well as exposures to small businesses, private clients and other retail customers without mortgage financing.

– Equity: consisting of instruments that have no stated or predetermined maturity and represents a residual interest in the net assets of an entity.

– Other assets: consisting of the remainder of exposures to which UBS is exposed, mainly non-counterparty-related assets.

Governance over Pillar 3 disclosures

The Board of Directors (BoD) and senior management are responsible for establishing and maintaining an effective internal control structure over the disclosure of financial information, including Pillar 3 disclosures. In line with BCBS and FINMA requirements, we have a BoD-approved Pillar 3 disclosure governance policy in place, which includes information on the key internal controls and procedures designed to govern the preparation, review and sign-off of Pillar 3 disclosures. This Pillar 3 report has been verified and approved in line with this policy.

Our approach to measuring risk exposure and risk-weighted assets

Depending on the intended purpose, the measurement of risk exposure that we apply may differ. Exposures may be measured for financial accounting purposes under International Financial Reporting Standards (IFRS), for deriving our regulatory capital requirement or for internal risk management and control purposes. Our Pillar 3 disclosures are generally based on measures of risk exposure used to derive the regulatory capital required under Pillar 1. Our RWA are calculated according to the BCBS Basel III framework, as implemented by the Swiss Capital Adequacy Ordinance issued by the Swiss Federal Council and by the associated circulars issued by the FINMA.

The table below provides a summary of the approaches we use for the main risk categories to determine the regulatory risk exposure and RWA. Our RWA are calculated according to the BCBS Basel III framework, as implemented by the Swiss Capital Adequacy Ordinance issued by the Swiss Federal Council.

| Category | Definition of risk | Regulatory risk exposure | Risk-weighted assets
(RWA) |
| --- | --- | --- | --- |
| I. Credit risk | | | |
| Credit risk | Credit risk
is the risk of a loss resulting from the failure of a counterparty to meet
its contractual obligations toward UBS arising from transactions such as
loans, debt securities held in our banking book and undrawn credit
facilities. Refer to section
4 Credit risk | Exposure at
default (EAD) is the amount we expect a counterparty to owe us at the time of
a possible default. For banking products, the EAD generally equals the IFRS
carrying value as of the reporting date. The EAD is expected to remain
constant over the 12-month period. For loan commitments, a credit conversion
factor is applied to model expected future drawdowns over the 12-month
period. | We apply two
approaches to measure credit risk RWA: – Advanced
internal ratings-based (A-IRB) approach , applied for the majority of
our businesses. Counterparty risk weights are determined by reference to
internal probability of default and loss given default estimates. – Standardized
approach (SA), generally based on external ratings for a subset of
our credit portfolio where internal measures are not available. |
| Non-counterparty-
related risk | Non-counterparty-related
risk (NCPA) denotes the risk of a loss arising from changes in value or from
liquidation of assets not linked to any counterparty, for example, premises,
equipment and software, and deferred tax assets on temporary differences. Refer to section
2 Regulatory exposures and risk-weighted assets. | The IFRS
carrying value is the basis for measuring NCPA exposure. | We measure
non-counterparty-related risk RWA by applying prescribed regulatory risk
weights to the NCPA exposure. |
| Equity
positions in the banking book | Risk from
equity positions in the banking book refers to the investment risk arising
from equity positions and other relevant investments or instruments held in
our banking book. Refer to section
4 Credit risk | The IFRS
carrying value is the basis for measuring risk exposure for equity securities
held in our banking book, but reflecting a net position. | We measure
the RWA from equity positions in the banking book by applying prescribed
regulatory risk weights to our listed and unlisted equity exposures. |

| Category | Definition of risk | Regulatory risk exposure | Risk-weighted assets
(RWA) |
| --- | --- | --- | --- |
| II. Counterparty credit
risk | | | |
| Counterparty
credit risk | Counterparty
credit risk is the risk that a counterparty for over-the-counter (OTC)
derivatives, exchange-traded derivatives (ETD) or securities financing
transactions (SFTs) will default before the final settlement of a transaction
and cause a loss to the bank if the transaction has a positive economic value
at the time of default. Refer to section
5 Counterparty credit risk. | We primarily
use internal models to measure counterparty credit risk exposures to third
parties. All internal models are approved by FINMA. – For
OTC derivatives and ETD we apply the effective expected positive
exposure (EEPE) and stressed expected positive exposure (stressed EPE) as
defined in the Basel III framework. – For
SFTs we apply the close-out period approach. In certain
instances where risk models are not available: – Exposure
on OTC derivatives and ETD is calculated considering the net positive
replacement values and potential future exposure. – Exposure
for SFTs is based on the IFRS carrying value, net of collateral
mitigation. | We apply two
approaches to measure counterparty credit risk RWA: – Advanced
internal ratings-based (A-IRB) approach , applied for the majority of our businesses.
Counterparty risk weights are determined by reference to internal
counterparty ratings and loss given default estimates. – Standardized
approach (SA), generally
based on external ratings for a subset of our credit portfolio, where
internal measures are not available. We apply an
additional credit valuation adjustment (CVA) capital charge to hold capital
against the risk of mark-to-market losses associated with the deterioration
of counterparty credit quality. |
| Settlement
risk | Settlement
risk is the risk of loss resulting from transactions that involve exchange of
value (e.g., security versus cash) where we must deliver without first being
able to determine with certainty that we will receive the countervalue. Refer to section
2 Regulatory exposures and risk-weighted assets. | The IFRS
carrying value is the basis for measuring settlement risk exposure. | We measure
settlement risk RWA through the application of prescribed regulatory risk
weights to the settlement risk exposure. |
| III. Securitization
exposures in the banking book | | | |
| Securitization
exposures in the banking book | Exposures arising from traditional and synthetic
securitizations held in our banking book. Refer to section 7 Securitizations. | The IFRS carrying value after eligible regulatory
credit risk mitigation and credit conversion factor is the basis for
measuring securitization exposure. | We apply the following approaches to measure securitization exposure RWA: – Internal
ratings-based approach (SEC-IRBA) , considering the advanced IRB risk weights, if the
securitized pool largely consists of IRB positions and internal ratings are
available. – External
ratings-based approach (SEC-ERBA) , in case the IRB approach cannot be applied, risk
weights are applied based on external ratings, provided that we are able to
demonstrate our expertise in critically reviewing and challenging the
external ratings. – Standardized
approach (SEC-SA) or 1,250% risk weight factor, in case none of the aforementioned approaches
can be applied, we would apply the standardized approach where the
delinquency status of a significant portion of the underlying exposure can be
determined or a risk weight of 1,250%. For
re-securitization exposures we apply either the standardized approach or a
risk weight factor of 1,250%. |

| Category | Definition of risk | Risk-weighted assets
(RWA) |
| --- | --- | --- |
| IV. Market risk | | |
| Value- at-risk (VaR) | VaR is a
statistical measure of market risk, representing the market risk losses that
could potentially be realized over a set time horizon (holding period) at an
established level of confidence. For regulatory VaR, the holding period is 10
days and the confidence level is 99%. Refer to section
8 Market risk. | The VaR
component of market risk RWA is calculated by taking the maximum of the
period-end VaR and the product of the average VaR for the 60 trading days
immediately preceding the period end and a VaR multiplier. The quantity is
then multiplied by a risk weight factor of 1,250% to determine RWA. The VaR
multiplier is dependent on the number of VaR backtesting exceptions within
the most recent 250-business-day window. |
| Stressed VaR (SVaR) | SVaR is a
10-day 99% VaR measure that is estimated with model parameters that are
calibrated to historical data covering a one-year period of significant
financial stress relevant to the firm’s current portfolio. Refer to section
8 Market risk. | The
derivation of SVaR RWA is similar to the one explained above for VaR. Unlike
VaR, SVaR is computed weekly, and as a result the average SVaR is computed
over the most recent 12 observations. |
| Add-on for
risks-not-in- VaR (RniV) | Potential
risks that are not fully captured by our VaR model are referred to as RniV.
We have a framework to identify and quantify these potential risks and
underpin them with capital. Refer to section
8 Market risk. | Our RniV
framework is used to derive the RniV-based component of the market risk RWA,
which is approved by FINMA. Starting in the second quarter of 2018, RniV and
RWA resulting from RniV are recalibrated on a monthly basis. As the RWA
from RniV are add-ons, they do not reflect any diversification benefits
across risks capitalized through VaR and SVaR. |
| Incremental risk charge (IRC) | The IRC
represents an estimate of the default and rating migration risk of all
trading book positions with issuer risk, except for equity products and
securitization exposures, measured over a one-year time horizon at a 99.9%
confidence level. Refer to section
8 Market risk. | The IRC is
calculated weekly, and the results are used to derive the IRC-based component
of the market risk RWA. The derivation is similar to that for VaR- and
SVaR-based RWA, but without a VaR multiplier. |
| Comprehensive
risk measure (CRM) | The CRM is
an estimate of the default and complex price risk, including the convexity
and cross-convexity of the CRM portfolio across credit spread, correlation
and recovery, measured over a one-year time horizon at a 99.9% confidence
level. Refer to section
8 Market risk. | The CRM is
calculated weekly, and the results are used to derive the CRM-based component
of the market risk RWA. The calculation is subject to a floor equal to 8% of
the equivalent capital charge under the specific risk measure (SRM) for the
correlation trading portfolio. |

| Category | Definition of risk | Regulatory risk exposure | Risk-weighted assets
(RWA) |
| --- | --- | --- | --- |
| Securitization
/ re-securitization
in the trading book | Risk arising
from traditional and synthetic securitizations held in our trading book. Refer to section
7 Securitizations and section 7 Market risk. | The exposure
is equal to the fair value of the net long or short securitization position. | We measure
trading book securitization RWA using two approaches: – Ratings-based
approach, applying risk weights based on external ratings. – Supervisory formula approach , considering the A-IRB risk weights for certain exposures where external ratings are not
available. |
| V. Operational risk | | | |
| Operational risk | Operational
risk is the risk of loss resulting from inadequate or failed internal
processes, people and systems or from external events, including cyber risk.
Operational risk includes, among others, legal risk, conduct risk and
compliance risk. Refer to section
9 Operational risk. | | We use the
advanced measurement approach to measure operational risk RWA in accordance
with FINMA requirements. |

Section 1 Key metrics

Key metrics of the fourth quarter of 2018

Quarterly | The table below is based on Basel Committee on Banking Supervision (BCBS) Basel III phase-in rules. During the fourth quarter of 2018, common equity tier 1 (CET1) capital decreased by USD 0.7 billion to USD 34.1 billion, mainly reflecting the accruals of capital returns to shareholders. Risk-weighted assets (RWA) increased by USD 6.7 billion to USD 263.7 billion, mainly due to increases of USD 8.3 billion in market risk RWA and USD 2.7 billion in credit risk RWA, partly offset by decreases of USD 3.4 billion in operational risk RWA and USD 1.1 billion in counterparty credit risk RWA. Leverage ratio exposure remained largely stable as in previous quarters.

Effective from 31 December 2018, UBS opted to phase in the effects from IFRS 9 expected credit loss (ECL) on CET1 capital, if any, over a five-year transitional period. This conclusion did not have a material effect on our CET1 capital as of 31 December 2018. p

which is separately reported in line 15 “Settlement risk.” Includes RWA with
central counterparties. New regulation for the calculation of RWA for
exposure to central counterparties will be implemented by 1 January 2020. The
split between the subcomponents of counterparty credit risk refers to the
calculation of the exposure measure. 5 Calculated in accordance with the
current exposure method (CEM), until SA-CCR is implemented by 1 January
2020. 6 Includes investments in funds. Items subject to threshold
deduction treatments that do not exceed their respective threshold are risk
weighted at 250% (31 December 2018: RWA USD 2,583 million;
30 September 2018: RWA USD 2,041 million; 30 June 2018: RWA USD

calculation of RWA for investments in funds will be implemented by
1 January 2020. 8 Calculated on the basis of the former securitization
rules applicable until 31 December 2017. 9 Includes items subject to
threshold deduction treatments that do not exceed their respective threshold
and risk weighted at 250%. Items subject to threshold deduction treatments
are significant investments in common shares of non-consolidated financial
institutions (banks, insurance and other financial entities) and deferred tax
assets arising from temporary differences, both of which are measured against
their respective threshold. 10 No floor effect, as 80% of our Basel I RWA
including the RWA equivalent of the Basel I capital deductions do not exceed
our Basel III RWA including the RWA equivalent of the Basel III capital
deductions. For the status of the finalization of the Basel III capital
framework, refer to the “Regulatory and legal developments” section of our
Annual Report 2018, available under “Annual reporting” at
www.ubs.com/investors, which outlines how the proposed floor calculation
would differ in significant aspects from the current approach.

UBS Group AG consolidated

The table below is aligned with the principles applied in “OV1: Overview of RWA,” and presents the net exposure at default (EAD) and RWA by risk type and FINMA-defined asset class, which forms the basis for the calculation of RWA. These exposures are then grouped into the advanced internal ratings-based (A-IRB) / model-based approaches and standardized approach. For credit risk, this defines the method used to derive the risk weight factors, through either internal ratings (A-IRB) or external ratings (standardized approach). The split between A-IRB / model-based approaches and standardized approach for counterparty credit risk refers to the exposure measure, whereas the split in templates CCR3 and CCR4 refers to the risk weighting approach. Market and operational risk RWA are derived using model calculations and are therefore included in the model-based approach columns.

The table provides references to sections in this report containing more information on the specific topics.

UBS Group AG consolidated

Annual | The table on the previous page provides a breakdown of the IFRS balance sheet into the risk types used to calculate our regulatory capital requirements. Receivables and payables from securities financing transactions, cash collateral receivables and payables on derivative instruments, financial assets at fair value held for trading, derivative financial instruments, and financial assets at fair value not held for trading are subject to regulatory capital charges in both the market risk and the counterparty credit risk categories. In addition, financial assets measured at fair value through profit or loss and financial assets measured at fair value through other comprehensive income include securities that were pledged as collateral. These securities are also considered in the counterparty credit risk framework, as collateral posted is subject to counterparty credit risk. p

Explanation of the difference between the IFRS and regulatory scope of consolidation

Quarterly | The scope of consolidation for the purpose of calculating Group regulatory capital is generally the same as the consolidation scope under International Financial Reporting Standards (IFRS) and includes subsidiaries that are directly or indirectly controlled by UBS Group AG and active in banking and finance. However, subsidiaries consolidated under IFRS whose business is outside the banking and finance sector are excluded from the regulatory scope of consolidation.

The key difference between the IFRS and regulatory capital scope of consolidation as of 31 December 2018 relates to investments in insurance, real estate and commercial companies as well as investment vehicles that are consolidated under IFRS, but not for regulatory capital purposes, where they are subject to risk-weighting.

The table below provides a list of the most significant entities that were included in the IFRS scope of consolidation, but not in the regulatory capital scope of consolidation. These entities account for most of the difference between the “Balance sheet in accordance with IFRS scope of consolidation” and the “Balance sheet in accordance with regulatory scope of consolidation” columns in the “CC2: Reconciliation of accounting balance sheet to balance sheet under the regulatory scope of consolidation” table and such difference is mainly related to financial assets at fair value not held for trading and other financial liabilities designated at fair value. As of 31 December 2018 , entities consolidated under either the IFRS or the regulatory scope of consolidation did not report any significant capital deficiencies.

In the banking book, certain equity investments are consolidated neither under IFRS nor under the regulatory scope. As of 31 December 2018 , these investments mainly consisted of infrastructure holdings and joint operations (e.g., settlement and clearing institutions, stock and financial futures exchanges) and included our participation in the SIX Group. These investments were risk weighted based on applicable threshold rules.

More information on the legal structure of the UBS Group and on the IFRS scope of consolidation is provided on pages 12–13 and 328–329, respectively, of our Annual Report 2018, available under “Annual reporting” at www.ubs.com/investors . p

million, which are excluded from the credit risk tables CR1, CR2, CR3 and CRB
in section 3 of this report, resulting in IFRS carrying values reflected in
the credit risk section of USD 531,975 million. However, credit risk tables
CR4 and CR5 include non-counterparty-related risk and credit risk table CR10
includes equity positions in the banking book, both not subject to the threshold
deduction approach. 2 Includes the amounts of financial instruments and
cash collateral considered as netting per relevant netting agreement so as
not to exceed the net amount of financial assets presented on the balance
sheet; i.e., over-collateralization, where it exists, is not reflected in the
table. 3 Includes exposure amounts considered for regulatory purposes for
non-cash collateral provided on derivative transactions. 4 Exposure at
default is only calculated for securitization exposures in the trading book,
resulting in a difference between carrying values and exposure amounts
considered for regulatory purposes. The effect on the total exposure is
higher, since certain exposures are subject to regulatory capital charges in
both the market risk and the counterparty credit risk categories. | | | | | | |

Regulatory exposures

Annual | The table above illustrates the key differences between regulatory exposure amounts and accounting carrying values under the regulatory scope of consolidation. In addition to the accounting carrying values, the regulatory exposure amount includes:

– off-balance sheet amounts (line 4)

– potential future exposure (PFE) for derivatives, offset by netting where an enforceable master netting agreement is in place, and by eligible financial collateral deductions (line 6)

– effects from the model calculation of effective expected positive exposure (EEPE) applied to derivatives (line 6)

– any netting and collateral mitigation on securities financing transactions (SFTs) through the application of the close-out period approach or the comprehensive measurement approach (line 7)

– effect of collateral mitigation in the banking book (line 8)

The regulatory exposure amount excludes prudential filters (line 5), comprising items subject to deduction from capital, which are not risk weighted. In addition, exposures that are only subject to market risk do not create any regulatory exposure, as their risk is reflected as part of our market risk RWA calculation (line 8). p

Section 4 Credit risk

Introduction

This section provides information on the exposures subject to the Basel III credit risk framework, as presented in the “Regulatory exposures and risk-weighted assets” table on pages 16 –18 of this report. Information on counterparty credit risk is reflected in the “Counterparty credit risk” section on pages 55 –66 of this report. Securitization positions are reported in the “Securitizations” section on pages 72 –79 of this report.

The tables in this section provide details on the exposures used to determine the firm’s credit risk-related regulatory capital requirement. The parameters applied under the advanced internal ratings-based (A-IRB) approach are generally based on the same methodologies, data and systems we use for internal credit risk quantification, except where certain treatments are specified by regulatory requirements. These include, for example, the application of regulatory prescribed floors and multipliers, and differences with respect to eligibility criteria and exposure definitions. The exposure information presented in this section may therefore differ from our internal management view disclosed in the “Risk management and control” sections of our quarterly and annual reports. Similarly, the regulatory capital prescribed measure of credit risk exposure also differs from that defined under International Financial Reporting Standards (IFRS).

Credit risk exposure categories

Annual | The definitions of the FINMA-defined Pillar 3 credit risk exposure categories “Loans” and “Debt securities” as referred to in the “CR1: Credit quality of assets” and “CR3: Credit risk mitigation techniques – overview” tables in this section have been updated to reflect the new IFRS balance sheet structure under IFRS 9.

The Pillar 3 category “Loans” comprises financial instruments held with the intent to collect the contractual payments and includes the following IFRS balances to the extent that they are subject to the credit risk framework:

– balances at central banks

– loans and advances to banks

– loans and advances to customers

– other financial assets measured at amortized cost, excluding money market instruments, checks and bills and other debt instruments

– traded loans in the banking book that are included within Financial assets at fair value held for trading

– brokerage receivables

– loans including structured loans that are included within Financial assets at fair value not held for trading

– other non-financial assets

The Pillar 3 category “Debt securities” includes the following IFRS balances to the extent that they are subject to the credit risk framework:

– money market instruments, checks and bills and other debt instruments that are included within Other financial assets measured at amortized cost

– financial assets at fair value held for trading, excluding traded loans

– financial assets at fair value not held for trading, excluding loans

– financial assets measured at fair value through other comprehensive income

This section is organized in seven sub-sections.

Policies for past-due, non-performing and credit-impaired claims

Annual | We have adopted IFRS 9, Financial Instruments , effective as of 1 January 2018. IFRS 9 introduces a forward-looking expected credit loss (ECL) approach, which is intended to result in an earlier recognition of credit losses compared with the incurred-loss impairment approach for financial instruments under IAS 39, Financial Instruments: Recognition and Measurement , and the loss-provisioning approach for financial guarantees and loan commitments under IAS 37, Provisions, Contingent Liabilities and Contingent Assets .

In line with the regulatory definition, we report a claim as non-performing when (i) it is more than 90 days past due; (ii) it is subject to restructuring proceedings, where preferential conditions concerning interest rates, subordination, tenor etc. have been granted in order to avoid default of the counterparty (forbearance); or (iii) the counterparty is subject to bankruptcy / enforced liquidation proceedings in any form, even if there is sufficient collateral to cover the due payment.

UBS applies a single definition of default for classifying assets and determining the PD of its obligors for risk modeling purposes. The definition of default is based on quantitative and qualitative criteria. A counterparty is classified as defaulted at the latest when material payments of interest, principal or fees are overdue for more than 90 days, or more than 180 days for certain exposures in relation to loans to private and commercial clients in Personal & Corporate Banking, and to private clients of Global Wealth Management Region Switzerland. UBS does not consider the general 90-day presumption for default recognition appropriate for these latter portfolios based on an analysis of the cure rates, which demonstrated that strict application of the 90-day criterion would not accurately reflect the inherent credit risk. Counterparties are also classified as defaulted when bankruptcy, insolvency proceedings or enforced liquidation have commenced; obligations have been restructured on preferential terms (forbearance); or there is other evidence that payment obligations will not be fully met without recourse to collateral. The latter may be the case even if, to date, all contractual payments have been made when due. If a counterparty is defaulted, generally all claims against the counterparty are treated as defaulted.

An instrument is classified as credit-impaired if the counterparty is defaulted, and / or the instrument is identified as purchased or originated credit-impaired (POCI). An instrument is POCI if it has been purchased with a material discount to its carrying amount following a risk event of the issuer or originated with a defaulted counterparty. Once a financial asset is classified as defaulted / credit-impaired (except POCIs), it is reported as a stage 3 instrument and remains as such unless all past due amounts have been rectified, additional payments have been made on time, the position is not classified as credit-restructured, and there is general evidence of credit recovery. A three-month probation period is applied before a transfer back to stages 1 or 2 can be triggered. However, most instruments remain in stage 3 for a longer period.

The tables below provide a breakdown of impaired exposures by geographical region and industry. The amounts shown are IFRS carrying values. The geographical distribution is based on the legal domicile of the counterparty or issuer. p

Semiannual | The total amount of defaulted loans and debt securities amounted to USD 3.3 billion as of 31 December 2018. The net increase of USD 54 million was driven by the gross USD 381 million increase in total defaulted exposures compared with 30 June 2018, mainly driven by various corporate clients in Switzerland, partly offset by amounts written off, defaulted loans returned to non-defaulted status and other changes. p

Restructured exposures

Annual | Under imminent payment default or where default has already occurred, we may grant concessions to borrowers in financial difficulties that we would otherwise not consider in the normal course of our business, such as preferential interest rates, extension of maturity, modifying the schedule of repayments, debt / equity swap, subordination, etc. When a forbearance measure takes place, each case is considered individually and the exposure is generally classified in default. Forbearance classification will remain, until the loan is collected or written off, non-preferential conditions are granted that supersede the preferential conditions or until the counterparty has recovered and the preferential conditions no longer exceed our risk appetite.

Contractual adjustments when there is no evidence of imminent payment default, or where changes to terms and conditions are within our usual risk appetite, are not considered to be forborne.

Refer to pages 151 –153 in our Annual Report 2018 for more information on our policies for restructured exposures.

The total carrying amount of loans increased by USD 3 billion to USD 462 billion in the second half of 2018. This was driven by an increase of USD 5 billion in cash and balances at central banks, mainly resulting from client-driven activity that affected funding consumption by the business divisions, contributing to unsecured exposures. This was partly offset by a decrease of USD 2 billion primarily as a result of lower lending in Global Wealth Management. The total carrying value of debt securities decreased by USD 8 billion to USD 69.9 billion mainly resulting from net transfers out of high-quality government bills and bonds held at fair value into SFTs in Group Asset and Liability Management (Group ALM). p

IRB approach – credit derivatives used as credit risk mitigation

Semiannual | We actively manage the credit risk in our corporate loan portfolios by utilizing credit derivatives. Single-name credit derivatives that fulfill the operational requirements prescribed by FINMA are recognized in the RWA calculation using the PD or rating (and asset class) assigned to the hedge provider. The PD (or rating) substitution is only applied in the RWA calculation when the PD (or rating) of the hedge provider is lower than the PD (or rating) of the obligor. In addition, default correlation between the obligor and hedge provider is taken into account through the double default approach. Credit derivatives with tranched cover or first-loss protection are recognized through the securitization framework. Refer to the “CCR6: Credit derivatives exposures” table in the “Counterparty credit risk” section on page 66 of this report for notional and fair value information on credit derivatives used as credit risk mitigation. p

Credit risk under the standardized approach

Annual | The standardized approach is generally applied where it is not possible to use the advanced internal ratings-based (A-IRB) approach. The standardized approach requires banks, where possible, to use risk assessments prepared by external credit assessment institutions (ECAI) or export credit agencies to determine the risk weightings applied to rated counterparties. We use three FINMA-recognized ECAI to determine the risk weights for certain counterparties according to the BCBS-defined asset classes: Standard & Poor’s, Moody’s Investors Service and Fitch Ratings.

The mapping of external ratings to the standardized approach risk weights is determined by FINMA and published on its website. There were no changes in the ECAI used compared with 31 December 2017.

Debt instruments are risk-weighted in accordance with the specific issue ratings available. In case there is no specific issue rating published by the ECAI, the issuer rating is applied to the senior unsecured claims of that issuer subject to the conditions prescribed by FINMA. For the asset classes Retail, Equity and Other assets, we apply the regulatory prescribed risk weights independent of an external credit rating. p

As of 31 December 2018, exposures before the application of CCFs decreased by USD 21.6 billion to USD 774.6 billion. This decrease was primarily related to a reduction in Lombard lending in Global Wealth Management, which decreased exposures before CCF and CRM by USD 12.1 billion with a reduction in EAD post-CCF and post-CRM of USD 10 billion. This was partly offset by an increase of USD 2.5 billion on exposures before CCF and CRM and post-CCF and post-CRM, due to the revision of the methodology applied for Lombard lending transactions in Japan. There was a USD 6.5 billion reduction in exposures before CCF and CRM and post-CCF and post-CRM in the asset classes “Central governments and central banks” and “Public-sector entities and multilateral development banks”, reflecting a decrease in high-quality liquid assets (HQLA). Information on credit risk RWA for the third quarter of 2018, including details on movements in RWA, is provided on pages 6–7 in our 30 September 2018 UBS Group AG and significant regulated subsidiaries and sub-groups report for the third quarter of 2018, available under “Pillar 3 disclosures” at www.ubs.com/investors and for the fourth quarter on pages 46–4 7 of this report. p

Credit risk risk-weighted assets under the A-IRB approach

This section provides disclosures on the quarterly credit risk RWA development for the credit risk measured under the A-IRB approach. The table below provides definitions of components driving the RWA as applied in the table on the following page.

Definitions of credit risk and counterparty credit risk RWA movement table components for CR8 and CCR7

References in the table below link to the line numbers provided in the movement tables on pages 46 and 57 of this report.

Reference	Description	Definition
2	Asset size	Movements arising in the ordinary course
of business, such as new transactions, sales and write-offs.
3	Asset quality / Credit quality of
counterparties	Movements resulting from changes in the
underlying credit quality of counterparties. These are caused by changes to
risk parameters, such as counterparty ratings, loss given default estimates
or credit hedges.
4	Model updates	Movements arising from the
implementation of new models and from parameter changes to existing models.
The RWA effect of model updates is estimated based on the portfolio at the
time of the change.
5	Methodology and policy	Movements due to methodological changes
in calculations driven by regulatory policy changes, including revisions to
existing regulations, new regulations and add-ons mandated by the regulator.
The effect of methodology and policy changes on RWA is estimated based on the
portfolio at the time of the change.
6	Acquisitions and disposals	Movements as a result of disposal or
acquisition of business operations, quantified based on the credit risk
exposures as of the end of the quarter preceding a disposal or following an
acquisition. Purchases and sales of exposures in the ordinary course of
business are reflected under asset size.
7	Foreign exchange movements	Movements as a result of exchange rate
changes of the transaction currencies against the US dollar.
8	Other	Movements due to changes that cannot be
attributed to any other category.

UBS Group AG consolidated

Development in the fourth quarter of 2018

Quarterly | Credit risk RWA under the advanced internal ratings-based (A-IRB) approach increased by USD 1.3 billion to USD 87.0 billion as of 31 December 2018. As presented in the “CR8: RWA flow statements of credit risk exposures under IRB” table below, the RWA increase of USD 2.7 billion from model updates was primarily driven by the continued phasing-in of RWA increases related to: probability of default (PD) and loss given default (LGD) changes from the implementation of revised models for Swiss residential mortgages and income-producing real estate; the new LGD model for unsecured financing and commercial self-used real estate; and calibration of aircraft leasing PD and LGD parameters, together resulting in an increase of USD 2.3 billion in Personal & Corporate Banking and USD 0.3 billion in Global Wealth Management. In addition, regulatory add-ons increased RWA by USD 0.3 billion due to a higher internal ratings-based (IRB) multiplier on Investment Bank exposures to corporates. p

shares of non-consolidated financial institutions (banks, insurance and other
financial entities) that are subject to the threshold treatment and risk
weighted at 250%. 2 RWA are calculated post-application of the A-IRB
multiplier of 6%, therefore the respective risk weight is higher than 300%
and 400%. 3 The exposure amount for equities in the banking book is based
on the net position. | | | | | |

Section 5 Counterparty credit risk

Introduction

Annual | Counterparty credit risk (CCR) arises from over-the-counter (OTC) and exchange-traded derivatives (ETD), securities financing transactions (SFTs) and long settlement transactions. Within traded products, we determine the regulatory credit exposure on the majority of our derivatives portfolio by applying the effective expected positive exposure (EPE) and stressed expected positive exposure (stressed EPE) as defined in the Basel III framework. For the rest of the portfolio we apply the current exposure method (CEM) based on the replacement value of derivatives in combination with a regulatory prescribed add-on. For the majority of securities financing transactions (securities borrowing, securities lending, margin lending, repurchase agreements and reverse repurchase agreements), we determine the regulatory credit exposure using the close-out period (COP) approach.

The counterparty credit risk-related tables in this report correspond to the CCR by asset class that is provided in the “Regulatory exposures and risk-weighted assets” table on page 16–18 of this report. p

This section is structured into three sub-sections:

Counterparty credit risk management

Annual | Refers to disclosures on our risk management objectives, policies and risk management process, operating limits for CCR exposures, wrong-way risks and the effect of a credit rating downgrade. p

Counterparty credit risk risk-weighted assets

Quarterly | Comprises disclosures on the quarterly credit risk RWA development. p

Counterparty credit exposure

Semiannual | Exposure at default (EAD) post credit-risk mitigation (CRM) related to counterparty credit risk (CCR) decreased by USD 11.2 billion to USD 100.6 billion, whereas RWA increased by USD 0.8 billion to USD 32.1 billion as of 31 December 2018. EAD post CRM on derivative exposures decreased by USD 11.5 billion and RWA by USD 2.2 billion, primarily in our Foreign exchange, Rates and Credit and Equities businesses within the Investment Bank and Group ALM, largely as a result of client-driven decreases and fair value changes. RWA from securities financing transactions increased by USD 3 billion, mainly due to the revision of the methodology applied for structured margin lending transactions. p

for derivative transactions. | | | | | | | |

Semiannual | In addition to the default risk capital requirements for CCR based on the advanced internal ratings-based (A-IRB) or standardized approach, we are required to add a capital charge to derivatives to cover the risk of mark-to-market losses associated with the deterioration of counterparty credit quality, referred to as the CVA. The advanced CVA VaR approach has been used to calculate the CVA capital charge where we apply the IMM. Where this is not the case, the standardized CVA approach has been applied. More information on our portfolios subject to the CVA capital charge as of 31 December 2018 is provided in the table below. p

Section 6 Comparison of A-IRB approach and standardized approach for credit risk

Background

Annual | In accordance with current prudential regulations, FINMA has approved our use of the advanced internal ratings-based (A-IRB) approach for calculating the required capital for a majority of our credit risk exposures.

The principal differences between the standardized approach (SA) and the A-IRB approach identified below are based on the current SA rules without consideration of the material revisions announced by the Basel Committee on Banking Supervision (BCBS) in December 2017.

We believe that advanced approaches that adequately capture economic risks are paramount for the appropriate representation of the capital requirements related to risk-taking activities. Within a strong risk control framework and in combination with robust stress testing practices, strict risk limits, as well as leverage and liquidity requirements, advanced approaches promote a proactive risk culture, putting the right incentives in place to prudently manage risks.

Refer to the “Introduction and basis for preparation” section of this report for more information on FINMA-defined asset classes. p

Key methodological differences between A-IRB and current SA approaches

Annual | In line with the BCBS objective, the A-IRB approach seeks to balance the maintenance of prudent levels of capital while encouraging, where appropriate, the use of advanced risk management techniques. By design, the calibration of the current SA rules and the A-IRB approaches is such that low-risk, short-maturity, well-collateralized portfolios across the various asset classes (with the exception of Central governments and central banks) receive lower risk weights under the A-IRB than under the current SA rules. Accordingly, RWA and capital requirements under the current SA rules would be substantially higher than under the A-IRB approach for lower-risk portfolios. Conversely, RWA for higher-risk portfolios are higher under the A-IRB than under the current SA approach.

Differences primarily arise due to the measurement of exposure at default (EAD) and to the risk weights applied. In both cases, the treatment of risk mitigation such as collateral can have a significant effect.

EAD measurement

For the measurement of EAD, the main differences relate to derivatives, driven by the differences between the internal model method (IMM) and the regulatory prescribed current exposure method (CEM).

The model-based approaches to derive estimates of EAD for derivatives and securities financing transactions reflect the detailed characteristics of individual transactions. They model the range of possible exposure outcomes across all transactions within the same legally enforceable netting set at various future time points. This assesses the net amount that may be owed to us or that we may owe to others, taking into account the effect of correlated market moves over the potential time it could take to close out a position. The calculation considers current market conditions and is therefore sensitive to deteriorations in the market environment.

In contrast, EAD under the regulatory prescribed rules are calculated as replacement costs at the balance sheet date plus regulatory add-ons, which take into account potential future market movements but at predetermined fixed rates, which are not sensitive to changes in market conditions. These add-ons are crudely differentiated by reference to only five product types and three maturity buckets. Moreover, the current regulatory prescribed rules calculation gives very limited recognition to the benefits of diversification across transactions within the same legally enforceable netting set. As a result, large diversified portfolios, such as those arising from our activities with other market-making banks, will generate much higher EAD under the current regulatory prescribed rules than under the model-based approach.

Risk weights

Under the A-IRB approach, risk weights are assigned according to the bank’s internal credit assessment of the counterparty to determine the probability of default (PD) and loss given default (LGD).

UBS Group AG consolidated

The PD is an estimate of the likelihood of a counterparty defaulting on its contractual obligations. It is assessed using rating tools tailored to the various categories of counterparties. Statistically developed scorecards, based on key attributes of the obligor, are used to determine PD for many of our corporate clients and for loans secured by real estate. Where available, market data may also be used to derive the PD for large corporate counterparties. For Lombard loans, Merton-type model simulations are used that take into account potential changes in the value of securities collateral. PD is not only an integral part of the credit risk measurement, but also an important input for determining the level of credit approval required for any given transaction. Moreover, for the purpose of capital underpinning, the majority of counterparty PDs are subject to a floor.

The LGD is an estimate of the magnitude of the likely loss if there is a default. The calculation takes into account the loss of principal, interest and other amounts such as workout costs, including the cost of carrying an impaired position during the workout process less recovered amounts. Importantly, LGD considers credit mitigation by way of collateral or guarantees, with the estimates being supported by our internal historical loss data and external information where available.

The combination of PD and LGD determined at the counterparty level results in a highly granular level of differentiation of the economic risk from different borrowers and transactions.

In contrast, the SA risk weights are largely reliant on external rating agencies’ assessments of the credit quality of the counterparty, with a 100% risk weight typically being applied where no external rating is available. Even where external ratings are available, there is only a coarse granularity of risk weights, with only four primary risk weights used for differentiating counterparties, with the addition of a 0% risk weight for AA– or better rated Central governments and central banks. Risk weights of 35% and 75% are used for mortgages and retail exposures, respectively.

The SA does not differentiate across transaction maturities except for interbank lending, albeit in a very simplistic manner considering only shorter or longer than three months. This has clear limitations. For example, the economic risk of a six-month loan to, say, a BB-rated US corporate is significantly different to that of a 10-year loan to the same borrower. This difference is evident from the distinction of PD levels based on ratings assigned by external rating agencies through their separate ratings for short-term and long-term debt for a given issuer.

The SA typically assigns lower risk weights to sub-investment grade counterparties than the A-IRB approach, thereby potentially understating the economic risk. Conversely, investment grade counterparties typically receive higher risk weights under the SA than under the A-IRB approach.

Maturity is also an important factor, with the A-IRB approach producing a higher capital requirement for longer maturity exposures than for shorter maturity exposures. Since the accelerated implementation of our strategy in 2012, the maturity effect has become particularly important as we had a notable shift from longer-term to shorter-term transactions in our credit portfolio.

Additionally, under the A-IRB approach we calculate expected loss measures that are deducted from common equity tier 1 (CET1) capital to the extent that they exceed general provisions, which is not the case under the SA.

Given the divergence between the SA and the economic risk, which is better represented under the A-IRB approach, particularly for lower-grade counterparties, there is a risk that applying the SA could incentivize higher risk-taking without a commensurate increase in required capital. p

Comparison of the A-IRB approach EAD and leverage ratio denominator by asset class

Annual | The following table shows EAD, average risk weight (RW), RWA and leverage ratio denominator (LRD) per asset class for Central governments and central banks, Multilateral development banks and Public-sector entities, Banks and securities dealers, Corporates and Retail credit risk and counterparty credit risk exposures subject to the A-IRB approach. LRD is the exposure measure used for the leverage ratio.

LRD estimates presented in the table reflect the credit risk and counterparty credit risk components of exposures only and are therefore not representative of the LRD requirement at bank level overall. The LRD estimates exclude exposures subject to market risk, non-counterparty-related risk and SA credit risk to provide a like-for-like comparison with the A-IRB credit risk EAD shown. p

Comparison of the A-IRB approach, the SA and LRD by asset class

Annual | The differences between the A-IRB approach, the SA and LRD per asset class are discussed below and on the following pages.

Asset classes Central governments and central banks, Multilateral development banks and Public sector entities

The regulatory net EAD for Central governments and central banks, Multilateral development banks (MDBs) and Public sector entities (PSEs) is USD 160 billion under the A-IRB approach. Since the vast majority of our exposure is driven by banking products exposures, the LRD is broadly in line with the A-IRB net EAD and we would expect a similar amount under the SA.

The charts below provide comparisons of risk weights for exposures to the asset classes Central governments and central banks, highly rated MDBs and other MDBs and PSEs calculated under the A-IRB approach and the SA. Risk weights under the A-IRB approach are shown for one-year and five-year maturities, both assuming an LGD of 45%. Our internal A-IRB ratings have been mapped to external ratings based on the long-term average of one-year default rates available from the major credit rating agencies, as described on page 147 of our Annual Report 2018.

The SA assigns a zero risk weight to central governments and central banks rated AA– and better and to highly rated MDB counterparties, while the A-IRB approach generally assigns risk weights higher than zero even for the highest-quality sovereign counterparties.

For other MDB and PSE counterparties rated AA- and better, the risk weight applied is 20%.

Despite this, we would expect an increase in average risk weight under the SA due to exposures to unrated counterparties such as sovereign wealth funds, which attract a 100% risk weight under the SA despite being generally considered very low risk, and short-term repo transactions with central banks rated below AA–, such as the Bank of Japan.

However, as the asset class is not a significant driver of RWA, we would expect any resulting increase in RWA to be relatively small.

Asset class Banks and securities dealers

The regulatory net EAD for exposures to the asset class Banks and securities dealers is USD 35 billion under the A-IRB approach. The A-IRB net EAD is lower compared with the LRD as a result of collateral mitigation on derivatives and securities financing transactions. We would expect the net EAD to increase significantly under the regulatory prescribed rules related to derivatives and securities financing transactions within the Investment Bank, due to the aforementioned methodological differences between the calculation of EAD under the two approaches.

The chart below provides a comparison of risk weights for SA.

The vast majority of our exposure toward Banks and securities dealers is of investment grade quality. The average contractual maturity of this exposure is closer to the one-year example provided in the chart above. Therefore, we would expect a higher average risk weight under the SA than the 25% average risk weight under the A-IRB approach. In combination with higher EAD, we would expect this to lead to significantly higher RWA for Banks and securities dealers under the SA.

Asset class Corporates

The regulatory net EAD for the asset class Corporates is USD 136 billion under the A-IRB approach. The A-IRB net EAD is lower compared with the LRD as a result of collateral mitigation on derivatives and securities financing transactions. We would expect the EAD figure to be higher under the regulatory prescribed rules related to derivatives and securities financing transactions due to the aforementioned methodological differences between the calculation of EAD under the two approaches. Derivatives and securities financing transactions currently account for 40% of the EAD for this asset class.

The following chart provides a comparison of risk weights for Corporates exposures calculated under the A-IRB approach and the SA. These exposures primarily arise from corporate lending and derivatives trading within the Investment Bank, and lending to large corporates and small and medium-sized enterprises within Switzerland. The comparison does not include the FINMA-required multiplier applied to Investment Bank Corporates exposures under A-IRB.

Investment grade counterparties typically receive higher risk weights under the SA than under the A-IRB approach. The majority of our Corporates exposures fall into this category. We would therefore expect risk weights for Corporates to be generally higher under the SA.

In addition, SA risk weights rely on external ratings, with a default weighting of 100% being applied where no external rating is available. Typically, counterparties with no external rating are riskier and thus have higher risk weights under the A-IRB approach. However, managed funds, which comprise nearly one-third of our Corporates EAD, typically have no debt and are therefore unrated. The SA applies a 100% risk weight to exposures to these funds. Under A-IRB, these funds are considered very low risk and have an average risk weight of 17%. We believe the SA significantly overstates the associated risk.

Conversely, for certain exposures, we consider the risk weight of 100% under the SA resulting from the absence of an external rating as insufficient, as evident from the hypothetical leveraged finance counterparty example in the table below. p

The table assumes two counterparties without external rating assignment.

that are liquid) | Internal rating assessment | Exposure maturity | A-IRB risk weight range | SA risk weight |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| Managed funds | NA | NA | 0 | 100% | AAA–A | < 1Y | 10–20% | 100% |
| Leveraged finance counterparty | < 2 | > 2.5 | > 50% | 0% | BB–C | > 5Y | 100–250% | 100% |

Asset class Retail

Sub-asset class Residential mortgages

The regulatory net EAD for the sub-asset class Residential mortgages is USD 142 billion under the A-IRB approach. Since the vast majority is driven by banking products exposures, the LRD is broadly in line with the A-IRB net EAD and we would expect a similar amount under the SA.

Due to the size of our personal and corporate banking business in Switzerland, our domestic portfolios represent a significant portion of our overall lending exposures, with the largest being loans secured by residential properties.

Our internal models assign risk weights to such loans by considering the debt service capacity of borrowers as well as the availability of other collateral, amongst other factors. These are important considerations for the Swiss market, where there is legal recourse to the borrower.

In contrast, and different to the assignment of risk weights for asset classes above, the SA only crudely differentiates the risk weights based on loan-to-value (LTV) ranges as shown in the table below.

The vast majority of our exposures would attract the minimum 35% risk weight under the SA, compared with the average of 15% observed under the A-IRB approach.

The difference is largely due to the current SA rules not giving benefit to the portion of exposures with an LTV below 67%. The vast majority of exposures fall within this category, as shown in the “Swiss mortgages: distribution of net exposure at default (EAD) across exposure segments and loan-to-value (LTV) buckets” table on page 138 of our Annual Report 2018.

Sub-asset class Lombard lending

Annual | The regulatory net EAD for the sub-asset class Lombard loans is USD 153 billion under the A-IRB approach as of 31 December 2018 and mainly arises in our wealth management businesses.

Eligible collateral is more limited under the SA than under A-IRB. However, the haircuts applied to collateral under the A-IRB approach are generally greater than those prescribed under the SA. Given this, we would expect the overall effect of applying current SA rules to be limited for this portfolio. p

Section 7 Securitizations

Introduction

Annual | This section provides details of traditional and synthetic securitization exposures in the banking and trading book based on the revised Basel III securitization framework, applicable since 1 January 2018, which incorporated changes to the treatment of banking book securitization positions.

In a traditional securitization, a pool of loans (or other debt obligations) is transferred to structured entities that have been established to own the loan pool and to issue tranched securities to third-party investors referencing this pool of loans. In a synthetic securitization, legal ownership of securitized pools of assets is typically retained, but associated credit risk is transferred to structured entities typically through guarantees, credit derivatives or credit-linked notes. Hybrid structures with a mix of traditional and synthetic features are disclosed as synthetic securitizations.

We act in different roles in securitization transactions. As originator, we create or purchase financial assets, which are then securitized in traditional or synthetic securitization transactions, enabling us to transfer significant risk to third-party investors. As sponsor, we manage, provide financing for or advice on securitization programs. In line with the Basel III framework, sponsoring includes underwriting activities. In all other cases, we act in the role of investor by taking securitization positions. p

Objectives, roles and involvement

Securitization in the banking book

Annual | Securitization positions held in the banking book include legacy risk positions in Corporate Center – Non-core and Legacy Portfolio. In 2018, for the majority of securitization carrying values on the balance sheet, we acted in the role of originator or investor.

Securitization and resecuritization positions in the banking book are measured at fair value, reflecting market prices where available or based on our internal pricing models. p

Securitization in the trading book

Annual | Securitizations held in the trading book are part of trading activities, including market-making and client facilitation, that could result in retention of certain securitization positions as an investor, including those that we may have originated or sponsored. In the trading book, securitization and resecuritization positions are measured at fair value, reflecting market prices where available, or based on our internal pricing models. p

Type of structured entities and affiliated entities involved in securitization transactions

Annual | For the securitization of third-party exposures, the type of structured entities or special purpose vehicles employed is selected as appropriate based on the type of transaction undertaken. Examples include limited liability companies, common law trusts and depositor entities.

We also manage or advise groups of affiliated entities that invest in exposures we have securitized or in structured entities that we sponsor.

Refer to Note 31 “Interests in subsidiaries and other entities” on pages 485–492 of our Annual Report 2018 for further information on interests in structured entities. p

Managing and monitoring of the credit and market risk of securitization positions

Annual | The banking book securitization and resecuritization portfolio is subject to specific risk monitoring, which may include interest rate and credit spread sensitivity analysis, as well as inclusion in firm-wide earnings-at-risk, capital-at-risk and combined stress test metrics.

The trading book securitization positions are also subject to multiple risk limits, such as management value-at-risk (VaR) and stress limits as well as market value limits. As part of managing risks within predefined risk limits, traders may utilize hedging and risk mitigation strategies. Hedging may, however, expose the firm to basis risks as the hedging instrument and the position being hedged may not always move in parallel. Such basis risks are managed within the overall limits. Any retained securitization from origination activities and any purchased securitization positions are governed by risk limits together with any other trading positions. Legacy trading book securitization exposure is subject to the same management VaR limit framework. Additionally, risk limits are used to control the unwinding, novation and asset sales process on an ongoing basis. p

Accounting policies

Annual | Refer to “Consolidation” on pages 328–329 in “Note 1 Summary of significant accounting policies” in the “Consolidated financial statements” section of our Annual Report 2018 for information on accounting policies that relate to securitization activities. p

Regulatory capital treatment of securitization exposures

Annual | With the implementation of the revised securitization framework as of 1 January 2018 for banking book securitization exposures, the following approaches to calculate the associated risk-weighted assets (RWA) have become available, each with specific preconditions that must be met:

– we use internal ratings (internal ratings-based approach (SEC-IRBA)) if the securitized pool largely consists of internal ratings-based positions and internal ratings are available;

– if the IRBA cannot be applied, we use external ratings (external ratings-based approach (SEC-ERBA)), if available, from Standard & Poor’s, Moody’s Investors Service and Fitch Ratings for securitization exposures, provided that we are able to demonstrate our expertise in critically challenging and reviewing the external ratings; or

– if we cannot apply the IRBA or ERBA methods, we apply the standardized approach (SEC-SA) where the delinquency status of a significant portion of the underlying exposure can be determined or a risk weight of 1,250%. Resecuritization positions are either treated under the standardized approach or with a 1,250% risk weight.

The selection of the external credit assessment institutions (ECAI) is based on the primary rating agency concept. This concept is applied, in principle, to avoid having the credit assessment by one ECAI applied to one or more tranches and by another ECAI to the other tranches, unless this is the result of the application of the specific rules for multiple assessments. If any two of the aforementioned rating agencies have issued a rating for a particular exposure, we would apply the lower of the two credit ratings. If all three rating agencies have issued a rating for a particular exposure, we would apply the middle of the three credit ratings. As of 31 December 2018, UBS did not use internal ratings for the purpose of the RWA calculation for securitization positions in the banking book. p

Securitization exposures in the banking and trading book

Semiannual | The tables “SEC1: Securitization exposures in the banking book” and “SEC2: Securitization exposures in the trading book” outline the carrying values on the balance sheet in the banking and trading books as of 31 December 2018, 30 June 2018 and 31 December 2017. The activity is further broken down by our role (originator, sponsor or investor) and by securitization type (traditional or synthetic). Amounts disclosed under the “Traditional” column of these tables reflect the total outstanding notes at par value issued by the securitization vehicle at issuance. For synthetic securitization transactions, the amounts disclosed generally reflect the balance sheet carrying values of the securitized exposures at issuance.

The tables “SEC3: Securitization exposures in the banking book and associated regulatory capital requirements – bank acting as originator or as sponsor” and “SEC4: Securitization exposures in the banking book and associated regulatory capital requirements – bank acting as investor” have been modified to reflect changes to the revised securitization framework.

Development in RWA related to securitization exposures in the banking book in the second half of 2018

RWA from securitization exposures from the banking book decreased by USD 0.6 billion due to rating changes for exposures under the external ratings-based approach.

For information on the development of RWA in the first half of 2018 refer to our 30 June 2018 Pillar 3 report – UBS Group and significant subsidiaries and sub-groups under “Pillar 3 disclosures” at www.ubs.com/investors . p

Section 8 Market risk

Overview

The amount of capital required to underpin market risk in the regulatory trading book is calculated using a variety of methods approved by FINMA. The components of market risk risk-weighted assets (RWA) are value-at-risk (VaR), stressed VaR (SVaR), an add-on for risks that are potentially not fully modeled in VaR (RniV), the incremental risk charge (IRC), the comprehensive risk measure (CRM) for the correlation portfolio and the securitization framework for securitization positions in the trading book. More information on each of these components is detailed in the following pages.

The table below presents an overview of Pillar 3 disclosures separately provided in our Annual Report 2018.

Market risk risk-weighted assets

Market risk RWA development in the quarter

Quarterly | This section provides disclosures on the quarterly market risk RWA developments for market risk measured under the internal models method. The four main components that contribute to market risk RWA are VaR, SVaR, IRC and the CRM. VaR and SVaR components include the RWA charge for RniV. The “MR2: RWA flow statements of market risk exposures under an internal models approach” table on the following page provides a breakdown of the market risk RWA movement in the fourth quarter of 2018 across these components, according to Basel Committee on Banking Supervision-defined movement categories. These categories are described below. p

Definitions of market risk RWA movement table components for MR2

References in the table below link to the line numbers provided in the movement table on the next page.

Reference	Description	Definition
1 / 8c	RWA as of previous and current
reporting period end (end of period)	Quarter-end RWA.
1a / 8b	Regulatory adjustment	Indicates the difference between rows 1
and 1b, and 8c and 8a, respectively.
1b / 8a	RWA at previous and current quarter
end (end of day)	For a given component (e.g., VaR), this
refers to the RWA computed whenever that component’s snapshot quarter-end
figure is higher than the 60-day average for regulatory VaR, and the 12-week
average for SVaR and IRC, thus determining the quarter-end RWA. The
regulatory adjustment would be zero if the quarter-end RWA were triggered by
the snapshot quarter-end figure.
	Movement of
end-of-day RWA
2	Movement in risk levels	Movements due to changes in positions
and risk levels.
3	Model updates / changes	Movements due to routine updates to
model parameters and model changes.
4	Methodology and policy	Movements due to methodological changes
in calculations driven by regulatory policy changes, including revisions of
existing regulations, new regulations and add-ons mandated by the regulator.
5	Acquisitions and disposals	Movements due to the disposal or
acquisition of business operations, quantified based on the market risk
exposures at the end of the quarter preceding a disposal or following an
acquisition. Purchases and sales of exposures in the ordinary course of
business are reflected in “Movements in risk levels.”
6	Foreign exchange movements	Movements due to changes in exchange
rates. Note that the effect of movements in exchange rates is captured in
“Movement in risk levels,” since exchange rate movements are part of the
effects of market movements on risk levels.
7	Other	Movements due to changes that cannot be
attributed to any other category.

RWA flow

Quarterly |

Market risk RWA increased by USD 8.3 billion in the fourth quarter, driven by asset size and other movements resulting from higher average regulatory and stressed value-at-risk (VaR) levels observed in the Investment Bank, mainly in its Equities business following significant market volatility. The increase from regulatory add-ons of USD 1.4 billion reflects updates from the monthly risks-not-in-VaR assessment and higher levels of regulatory VaR and stressed VaR.

The VaR multiplier remained unchanged at 3.0 compared with the third quarter of 2018. p

Value-at-risk

VaR definition

Annual | VaR is a statistical measure of market risk, representing the market risk losses that could potentially be realized over a set time horizon (holding period) at an established level of confidence. The measure assumes no change in the Group’s trading positions over the set time horizon.

We calculate VaR on a daily basis. The profit or loss distribution from which VaR is derived is generated by our internally developed VaR model. The VaR model simulates returns over the holding period of those risk factors to which our trading positions are sensitive, and subsequently quantifies the profit or loss effect of these risk factor returns on the trading positions. Risk factor returns associated with the risk factor classes of general interest rates, foreign exchange and commodities are based on a pure historical simulation approach, taking into account a five-year look-back window. Risk factor returns for selected issuer-based risk factors, such as equity price and credit spreads, are decomposed into systematic and residual, issuer-specific components using a factor model approach. Systematic returns are based on historical simulation, and residual returns are based on a Monte Carlo simulation. The VaR model profit and loss distribution is derived from the sum of the systematic and residual returns in such a way that we consistently capture systematic and residual risk. Correlations among risk factors are implicitly captured via the historical simulation approach. In modeling the risk factor returns, we consider the stationarity properties of the historical time series of risk factor changes. Depending on the stationarity properties of the risk factors within a given risk factor class, we choose to model the risk factor returns using absolute returns or logarithmic returns. The risk factor return distributions are updated on a fortnightly basis.

Although our VaR model does not have full revaluation capability, we source full revaluation grids and sensitivities from our front-office systems, enabling us to capture material non-linear profit or loss effects.

We use a single VaR model for both internal management purposes and determining market risk risk-weighted assets (RWA), although we consider different confidence levels and time horizons. For internal management purposes, we establish risk limits and measure exposures using VaR at the 95% confidence level with a one-day holding period, aligned to the way we consider the risks associated with our trading activities. The regulatory measure of market risk used to underpin the market risk capital requirement under Basel III requires a measure equivalent to a 99% confidence level using a 10-day holding period. In the calculation of a 10-day holding period VaR, we employ 10-day risk factor returns, whereby all observations are equally weighted.

Additionally, the population of the portfolio within management and regulatory VaR is slightly different. The population within regulatory VaR meets regulatory requirements for inclusion in regulatory VaR. Management VaR includes a broader population of positions. For example, regulatory VaR excludes the credit spread risks from the securitization portfolio, which are treated instead under the securitization approach for regulatory purposes.

We also use SVaR for the calculation of regulatory capital. SVaR adopts broadly the same methodology as regulatory VaR and is calculated using the same population, holding period (10-day) and confidence level (99%). However, unlike regulatory VaR, the historical data set for SVaR is not limited to five years, but spans the time period from 1 January 2007 to present. In deriving SVaR, we search for the largest 10-day holding period VaR for the current portfolio of the Group across all one-year look-back windows that fall into the interval from 1 January 2007 to present. SVaR is computed weekly. p

Derivation of VaR- and SVaR-based RWA

Annual | VaR and SVaR are used to derive the VaR and SVaR components of the market risk Basel III RWA, as shown in the “Regulatory exposures and risk-weighted assets” table on pages 16–18 of this report. This calculation takes the maximum of the respective period-end VaR measure and the product of the average VaR measure for the 60 trading days immediately preceding the period end and a VaR multiplier set by FINMA. The VaR multiplier, which was 3.0 as of 31 December 2018, is dependent upon the number of VaR backtesting exceptions within a 250-business-day window. When the number of exceptions is greater than four, the multiplier increases gradually from three to a maximum of four if 10 or more backtesting exceptions occur. This is then multiplied by a risk weight factor of 1,250% to determine RWA.

In addition to the VaR multiplier, at the time of the structural change to our VaR model in the first quarter of 2016, FINMA introduced a model multiplier of 1.3 to be applied in the calculation of VaR and SVaR RWA. This model multiplier was temporarily introduced to offset a reduction in VaR at the time, pending other improvements to the VaR model which are expected to increase VaR. This temporary multiplier has not yet been removed.

This calculation is set out in the table below. p

MR4: Comparison of VaR estimates with gains / losses

Semiannual | VaR backtesting is a performance measurement process in which the 1-day VaR prediction is compared with the realized 1-day profit & loss (P&L). We compute backtesting VaR using a 99% confidence level and one-day holding period for the population included within regulatory VaR. Since 99% VaR at UBS is defined as a risk measure that operates on the lower tail of the P&L distribution, 99% backtesting VaR is a negative number. Backtesting revenues exclude non-trading revenues, such as valuation reserves, fees and commissions and revenues from intraday trading, to provide for a like-for-like comparison. A backtesting exception occurs when backtesting revenues are lower than the previous day’s backtesting VaR.

Statistically, given the confidence level of 99%, two or three backtesting exceptions per year can be expected. More than four exceptions could indicate that the VaR model is not performing appropriately, as could too few exceptions over a prolonged period of time. However, as noted in the VaR limitations section above, a sudden increase or decrease in market volatility relative to the five-year window could lead to a higher or lower number of exceptions, respectively. Accordingly, Group-level backtesting exceptions are investigated, as are exceptional positive backtesting revenues, with results being reported to senior business management, the Group Chief Risk Officer and the Chief Risk Officer Market & Treasury Risk. Backtesting exceptions are also reported to internal and external auditors and to the relevant regulators.

The “Group: development of regulatory backtesting revenues and actual trading revenues against backtesting VaR” chart on the page below shows the 12-month development of backtesting VaR against the Group’s backtesting revenues and actual trading revenues for 2018. The chart shows both the 99% and the 1% backtesting VaR. The asymmetry between the negative and positive tails is due to the long gamma risk profile that has been run historically in the Investment Bank.

The actual trading revenues include, in addition to backtesting revenues, intraday revenues.

The number of negative backtesting exceptions within a 250-business-day window increased from one to two by the end of the year. The FINMA VaR multiplier for market risk RWA remained unchanged at 3.0 as of 31 December 2018. p

Risks-not-in-VaR

Risks-not-in-VaR definition

Annual | We have a framework to identify and quantify potential risks that are not fully captured by our VaR model. We refer to these as risks-not-in-VaR (RniV). This framework is used to underpin these potential risks with regulatory capital, calculated as a multiple of VaR and SVaR.

Our VaR model can be split into two components: the P&L representation and the risk factor model. This gives rise to two RniV categories: P&L representation RniV and risk factor RniV. P&L representation RniV arises from approximations made by the VaR model to quantify the effect of risk factor changes on the profit and loss of positions and portfolios. Risk factor RniV originate from an inadequate modeling of the stochastic behavior of the risk factors. p

Risks-not-in-VaR quantification

Annual | The RniV quantification is conducted on the basis of a quantitative approach that was developed within the Risk Methodology department, and that has been approved by FINMA. We quantify RniV on a monthly basis. The revised framework applies to both categories of RniV: P&L representation RniV as well as risk factor RniV. p

Risks-not-in-VaR mitigation

Annual | Material RniV items are monitored and controlled by means and measures other than VaR, such as position limits and stress limits. Additionally, there are ongoing initiatives to extend the VaR model to better capture these risks. p

Derivation of RWA add-on for risks-not-in-VaR

Annual | The RniV framework is used to derive the RniV-based component of the market risk Basel III RWA, using the aforementioned approach, which is approved by FINMA and subject to a recalibration frequency that is at least quarterly. As the RWA from RniV are add-ons, they do not reflect any diversification benefits across risks capitalized through VaR and SVaR.

The RniV VaR and SVaR capital ratios applicable during the fourth quarter are 107% for each.

FINMA continues to require that RniV stressed VaR capital be floored at RniV VaR capital. p

Incremental risk charge

Annual | Incremental risk charge (IRC) is the potential loss due to the defaults or credit migrations of issuers of non-securitized credit instruments in the trading book. IRC is calculated as the portfolio loss at the 99.9% percentile of the portfolio loss distribution over a one-year time horizon. It uses a multi-factor model applying the constant position assumption for all positions in the IRC portfolio: all positions are kept unchanged over the one-year time period.

The portfolio loss distribution is estimated using a Monte Carlo simulation approach. The simulation is performed in two steps: first, the distribution of credit ratings (including the defaulted state) at the one-year time horizon is estimated by a portfolio rating migration model, and second, default and migration losses conditional on credit events generated by the migration model are calculated and aggregated.

The portfolio rating migration model is of the Merton type: migrations of credit ratings are considered to be functions of the underlying asset value of a firm. The correlation structure of asset values is based on the SunGard APT factor model with factor loadings and volatilities homogenized within region-industry-size buckets. For the government bucket, a conservative expert-based correlation value is used. The transition matrix approach is utilized to set migration and default thresholds. The transition matrix for sovereign obligors is calibrated to the history of S&P sovereign ratings. The transition matrix for non-sovereigns is calibrated to the history of UBS internal ratings.

For each position related to a defaulted obligor, default losses are calculated based on the maximum default exposure measure (the loss in the case of a default event assuming zero recovery) and a random recovery concept. To account for potential basis risk between instruments, different recovery values may be generated for different instruments even if they belong to the same issuer. To calculate rating migration losses, a linear (delta) approximation is used. A loss due to a migration event is calculated as a change in the average credit spread due to the rating change, multiplied by the corresponding sensitivity of a position to changes in credit spreads.

The validation of the IRC model relies heavily on sensitivity analyses embedded into the annual model reconfirmation. p

Derivation of IRC-based RWA

Annual | IRC is calculated weekly and the results are used to derive the IRC-based component of the market risk Basel III RWA, as shown in the “Regulatory exposures and risk-weighted assets” table on pages 16–18 of this report. The derivation is similar to that for VaR- and SVaR-based RWA, but without a VaR multiplier, and is shown below. p

Comprehensive risk measure

Annual | The comprehensive risk measure (CRM) is an estimate of the default and complex price risk, including the convexity and cross-convexity of the CRM portfolio across credit spread, correlation and recovery, measured over a one-year time horizon at a 99.9% confidence level. The calculation assumes a static portfolio with trade aging, a modeling choice consistent with the portfolio being hedged in a back-to-back manner. The model scope covers collateralized debt obligation (CDO) swaps, credit-linked notes (CLNs), 1st- and nth-to-default swaps and CLNs and hedges for these positions, including single-name credit default swaps (CDSs), CLNs and index CDSs.

The CRM profit and loss distribution is estimated using a Monte Carlo simulation of defaults, loss given defaults (LGDs) and market data changes over the next 12 months where spreads follow their own stochastic processes and are correlated to defaults. The risk engine loads the definition of all trades and, for each Monte Carlo scenario, generates the trade cash flows over the next 12 months and revalues the trades on the horizon date. The revaluation relies on sampled FX rates, credit spreads and index bases and introduces a correlation skew by using stochastic correlations and stochastic LGDs. The correlation skew is calibrated at irregular intervals. The 99.9% negative quantile of the resulting profit and loss distribution is then taken to be the CRM result. Our CRM methodology is subject to minimum qualitative standards. p

Derivation of CRM-based RWA

Annual | CRM is calculated weekly, and the results are used to derive the CRM-based component of the market risk Basel III RWA, as shown in the “Regulatory exposures and risk-weighted assets” table on pages 16–18 of this report. The calculation is subject to a floor equal to 8% of the equivalent capital charge under the specific risk measure (SRM) for the correlation trading portfolio. The calculation is shown below. p

These positions may affect Other comprehensive income (OCI) or the income statement, depending on their accounting treatment.

Interest rate risk sensitivity to parallel shifts in yield curves

Annual | Interest rate risk in the banking book is not underpinned for capital purposes, but is subject to a regulatory threshold. As of 31 December 2018, the economic-value effect of an adverse parallel shift in interest rates of ±200 basis points on our banking book interest rate risk exposures was significantly below both the current threshold of 20% of eligible capital recommended by regulators and the new threshold of 15% of Tier 1 capital applicable as of 2019.

The interest rate risk sensitivity figures presented in the “Interest rate sensitivity – banking book” table on the next page represent the effect of +1, ±100 and ±200-basis-point parallel moves in yield curves on present values of future cash flows, irrespective of accounting treatment. In the prevailing negative interest rate environment for the Swiss franc in particular, and to a lesser extent for the euro and the Japanese yen, interest rates for Global Wealth Management and Personal & Corporate Banking client transactions are generally floored at 0%. Accordingly, for the purposes of this disclosure table, downward moves of 100 / 200 basis points are floored to ensure that the resulting shocked interest rates do not turn negative. The flooring results in non-linear sensitivity behavior.

The sensitivity of the banking book to rising rates was positive USD 1.0 million per basis point compared with approximately nil at prior year-end. This was mainly due to changes in US dollar sensitivity. In the third quarter of 2018, we implemented a transfer process of the interest rate risk from our Global Wealth Management in the Americas into Corporate Center – Group ALM, and adopted a replication model for the non-maturing deposits held in the US. This decreased the exposure to rising rates in Global Wealth Management to negative USD 0.1 million per basis point from negative USD 1.8 million per basis point.

The sensitivity of the banking book to rising rates includes the interest rate sensitivities arising from debt investments classified as Financial assets measured at fair value through other comprehensive income . The sensitivity of these positions to a 1-basis-point parallel increase in the yields of the respective instruments was approximately negative USD 2 million, unchanged from the prior year.

The sensitivity of the banking book to rising interest rates also includes interest rate sensitivities arising from interest rate swaps designated in cash flow hedges. Fair value gains or losses associated with the effective portion of these hedges are recognized directly in other comprehensive income (OCI) in equity. When the hedged forecast cash flows affect profit or loss, the associated gains or losses on the hedging derivatives are reclassified from OCI to profit or loss. These swaps are predominantly denominated in US dollars, euros and Swiss francs. A 1-basis-point parallel increase of underlying LIBOR curves would have decreased OCI by approximately USD 22 million, excluding adjustments for tax. p

capital instruments, which are available under the transitional rules of the
Swiss SRB framework to meet the going concern requirements until the earlier
of (i) their maturity or first call date or (ii) 31 December 2019, and to
meet gone concern requirements thereafter. Outstanding low-trigger loss-absorbing
tier 2 capital instruments are subject to amortization starting five years
prior to their maturity, with the amortized portion qualifying as gone
concern loss-absorbing capacity. Instruments available to meet gone concern
requirements are eligible until one year before maturity, with a haircut of
50% applied in the last year of eligibility. | | | | | | | | |

Prudent valuation

Annual | The table below provides a breakdown of prudent valuation adjustments to CET1 capital. These adjustments are incremental to the ones made under IFRS, which include adjustments for liquidity and model uncertainty as well as credit, funding and debit valuation adjustments.

Instruments that are measured as part of a portfolio of combined long and short positions are valued at mid-market levels to ensure consistent valuation of the long- and short component risks. A liquidity valuation adjustment is then made to the overall net long or short exposure to move the fair value to bid or offer as appropriate, reflecting current levels of market liquidity.

Uncertainties associated with the use of model-based valuations are incorporated into the measurement of fair value through the use of model reserves. These reserves reflect the amounts that the Group estimates should be deducted from valuations produced directly by models to incorporate uncertainties in the relevant modeling assumptions, in the model and market inputs used, or in the calibration of the model output to adjust for known model deficiencies.

To ensure compliance with the prudent valuation requirements, UBS has established systems, controls and governance around the valuation of positions measured at fair value.

Further details on the valuation adjustments in the financial accounts and related governance are provided in Note 24 Fair value measurement on pages 437–439 of our Annual Report 2018. p

Section 12 Leverage ratio

Basel III leverage ratio

Quarterly | The Basel Committee on Banking Supervision (BCBS) leverage ratio is calculated by dividing the period-end tier 1 capital by the period-end leverage ratio denominator (LRD). The LRD consists of IFRS on-balance sheet assets and off-balance sheet items. Derivative exposures are adjusted for a number of items, including replacement value and eligible cash variation margin netting, the current exposure method add-on and net notional amounts for written credit derivatives. The LRD also includes an additional charge for counterparty credit risk related to securities financing transactions. In addition, balance sheet assets deducted from our tier 1 capital are excluded from LRD, which led to a difference between phase-in and fully applied LRD for deferred tax assets and net defined benefit pension plan assets until 31 December 2017.

The “Reconciliation of IFRS total assets to BCBS Basel III total on-balance sheet exposures excluding derivatives and securities financing transactions” table below shows the difference between total IFRS assets per IFRS consolidation scope and the BCBS total on-balance sheet exposures, which are the starting point for calculating the BCBS LRD as shown in the “BCBS Basel III leverage ratio common disclosure” table on the next page. The difference is due to the application of the regulatory scope of consolidation for the purpose of the BCBS calculation. In addition, carrying values for derivative financial instruments and securities financing transactions are deducted from IFRS total assets. They are measured differently under BCBS leverage ratio rules and are therefore added back in separate exposure line items in the “BCBS Basel III leverage ratio common disclosure” table on the next page.

As of 31 December 2018, our BCBS Basel III leverage ratio was 5.1% and the BCBS Basel III LRD was USD 905 billion. p

Difference between the Swiss SRB and BCBS leverage ratio

Quarterly | The LRD is the same under Swiss SRB and BCBS rules. However, there is a difference in the capital numerator between the two frameworks. Under BCBS rules, only common equity tier 1 and additional tier 1 capital are included in the numerator. Under Swiss SRB we are required to meet going as well as gone concern leverage ratio requirements. Therefore, depending on the requirement, the numerator includes tier 1 capital instruments, tier 2 capital instruments and / or TLAC-eligible senior unsecured debt. p

Quarterly | During the fourth quarter of 2018, LRD decreased by USD 10 billion to USD 905 billion due to decreases in currency effects of USD 2 billion and in asset size and other movements of USD 8 billion. The LRD movements described below exclude currency effects. On-balance sheet exposures (excluding derivatives and securities financing transactions (SFTs)) decreased by USD 8 billion. A decrease in exposures in the Investment Bank, mainly resulting from client-driven reductions and trade unwinds within the Equities business, was partly offset by an increase in cash and balances in central banks in Corporate Center – Group Asset and Liability Management (Group ALM) as client-driven activity affected funding consumption by the business divisions. Derivative exposures decreased by USD 4 billion, reflecting decreased notional amounts and add-on exposures under the current exposure method from a net increase of client-driven trade terminations and maturities across all businesses within the Investment Bank. These decreases were partly offset by an increase in SFTs of USD 6 billion, primarily driven by reinvestment of cash and cash equivalents in Corporate Center – Group ALM and partly offset by lower prime brokerage receivables in the Investment Bank’s Equities business. p

High-quality liquid assets

Quarterly | High-quality liquid assets (HQLA) must be easily and immediately convertible into cash at little or no loss of value, especially during a period of stress. HQLA are assets that are of low risk and are unencumbered. Other characteristics of HQLA are ease and certainty of valuation, low correlation with risky assets, listing on a developed and recognized exchange, an active and sizable market and low volatility. Based on these characteristics, HQLA are categorized as Level 1 (primarily central bank reserves and government bonds) or Level 2 (primarily US and European agency bonds as well as non-financial corporate covered bonds). Level 2 assets are subject to regulatory haircuts and caps. p

Liquidity coverage ratio

Quarterly | In the fourth quarter of 2018, the UBS Group liquidity coverage ratio (LCR) increased by 1 percentage point to 136%, remaining above the 110% Group LCR minimum communicated by FINMA. The LCR increase was primarily driven by lower net cash outflows related to secured financing transactions. This was partly offset by decreased high-quality liquid assets due to lower average cash balances. p

Section 15 Requirements for global systemically important banks and related indicators

Annual | The Financial Stability Board (FSB) determined that UBS is a global systemically important bank (G-SIB), using an indicator-based methodology adopted by the Basel Committee on Banking Supervision (BCBS). Banks that qualify as G-SIBs are required to disclose the 12 indicators for assessing the systemic importance of G-SIBs as defined by the BCBS. These indicators are used for the G-SIB score calculation and cover the five categories size, cross-jurisdictional activity, interconnectedness, substitutability / financial institution infrastructure and complexity.

Based on the published indicators, G-SIBs are subject to additional CET1 capital buffer requirements in the range from 1.0% to 3.5%. These requirements were phased in from 1 January 2016 to 31 December 2018 and became fully effective on 1 January 2019. In November 2018, the FSB determined that, based on the year-end 2016 indicators, the requirement for UBS is 1.0%. As our Swiss SRB Basel III capital requirements exceed the BCBS requirements including the G-SIB buffer, UBS is not affected by the above.

In July 2018, the BCBS published a revised assessment methodology and higher loss absorbency requirements. These will take effect in 2021 and the higher loss absorbency surcharge would be applied in January 2023. We do not expect these changes to result in an increase of our additional CET1 capital buffer requirement. p

UBS AG consolidated capital and other regulatory information is provided in the UBS Group AG and UBS AG Annual Report 2018 available under “Annual reporting” at www.ubs.com/investors . Quarterly | The table below is based on BCBS Basel III phase-in rules. During the fourth quarter of 2018, CET1 capital decreased by USD 0.4 billion to USD 34.6 billion, mainly reflecting the accruals of capital returns to the shareholder UBS Group AG. RWA increased USD 6.6 billion to USD 256.2 billion, mainly due to increases of USD 8.3 billion in market risk RWA and USD 1.6 billion in credit and counterparty credit risk RWA, partly offset by a decrease of USD 3.4 billion in operational risk RWA. Leverage ratio exposure remained largely stable as in previous quarters.

Section 2 UBS AG standalone

Key metrics of the fourth quarter of 2018

Quarterly | The table below is based on BCBS Basel III phase-in rules. During the fourth quarter of 2018, CET1 capital remained largely stable. RWA increased by USD 4.8 billion to USD 292.9 billion, mainly reflecting a USD 7.2 billion increase in market risk RWA due to higher average regulatory and stressed value-at-risk levels, partly offset by a USD 3.0 billion decrease in operational risk RWA after the recalibration of the advanced measurement approach model used for calculation of operational risk capital. Leverage ratio exposure decreased by USD 19 billion to USD 601 billion, mainly due to on-balance sheet exposures (excluding derivative exposures and SFT).

Effective from 31 December 2018, UBS opted to phase in the effects from IFRS 9 expected credit loss (ECL) on CET1 capital, if any, over a five-year transitional period. This conclusion did not have an effect on our CET1 capital as of 31 December 2018. p

Swiss SRB going concern requirements and information

Quarterly | UBS AG standalone is considered a systemically relevant bank (SRB) under Swiss banking law and is subject to capital regulations on a standalone basis. Under Swiss SRB regulations, article 125 “Reliefs for financial groups and individual institutions” of the Capital Adequacy Ordinance stipulates that the Swiss Financial Market Supervisory Authority (FINMA) may grant, under certain conditions, capital relief to individual institutions to ensure that an individual institution’s compliance with the capital requirements does not lead to a de facto overcapitalization of the group of which it is a part.

FINMA granted relief concerning the regulatory capital requirements of UBS AG on a standalone basis by means of decrees issued on 20 December 2013 and 20 October 2017, the latter effective as of 1 July 2017 and partly replacing the former.

The FINMA decree issued in 2017 established the measure of total going concern capital for UBS AG. Common equity tier 1 (CET1) and high-trigger additional tier 1 capital instruments are eligible as going concern capital, and low-trigger tier 2 capital instruments remain eligible until the earlier of (i) their maturity or the first call date or (ii) 31 December 2019.

Capital requirements based on risk-weighted assets (RWA) and leverage ratio denominator (LRD) are the same under both the phase-in and fully applied rules. The capital requirements based on RWA include a minimum CET1 capital requirement of 10% plus the effects from countercyclical buffers (CCBs), and a total going concern capital requirement of 14.3% plus the effects from CCBs. The capital requirements based on LRD include a minimum CET1 capital requirement of 3.5% and a total going concern leverage ratio requirement of 5.0%. For direct and indirect investments, including holding of regulatory capital instruments of UBS AG in subsidiaries that are active in banking and finance, the FINMA decree introduced a risk-weighting approach, with a phase-in period until 1 January 2028. Starting 1 July 2017, these investments have been risk-weighted at 200%. As of 1 January 2019, the risk weights will gradually be raised by 5 percentage points per year for Swiss-domiciled investments and by 20 percentage points per year for foreign-domiciled investments until the fully applied risk weights are 250% and 400%, respectively.

More information on this change is provided in “Section 2 UBS AG standalone” of the UBS Group AG and significant regulated subsidiaries and sub-groups third quarter 2017 Pillar 3 report available under “Pillar 3 disclosures” at www.ubs.com/investors . p

rebate on the gone concern requirements, which was granted by FINMA and will
be phased in until 1 January 2020. Refer to the “Capital management” section
of our Annual Report 2018 for more information. 2 The total loss-absorbing
capacity ratio requirement of 20.91% is the current requirement based on the
transitional rules of the Swiss Capital Adequacy Ordinance including the
aforementioned rebate on the gone concern requirements. In addition, FINMA
has defined a total capital ratio requirement, which is the sum of 14.4% and
the effect of countercyclical buffer (CCB) requirements of 0.57%, of which
10% plus the effect of CCB requirements must be satisfied with CET1 capital.
These FINMA requirements will be effective until they are exceeded by the
Swiss SRB requirements based on the transitional rules. 3 Going concern
capital ratio requirements include CCB requirements of 0.57%. 4 Includes
applicable add-ons of 1.44% for RWA and 0.5% for LRD. 5 Includes
