5 Composition of Capital
5.1 Reconciliation of Regulatory Capital to Balance Sheet
Table 1 and Table 2 are mandatory disclosures prescribed in MAS Notice 637 requirements.
Table 1 shows the reconciliation between the Group's published consolidated balance sheet and the
regulatory capital components. Details of the regulatory capital components are set out in Table 2, as
referenced.
The scope of consolidation for accounting and regulatory purposes is similar, except that subsidiaries
which carry out insurance business are not consolidated for regulatory purpose. The list of the Group's
major insurance subsidiaries can be found in the Group's Annual Report. As at 31 December 2022, both
the total assets and the total equities of each of these subsidiaries were less than $1 billion.
Compared with 30 June 2022, key movements in the items under the column "Under regulatory scope of
consolidation" were mainly from retained earnings, lower other reserves, capital issuances, goodwill and
intangibles.

6 Leverage Ratio
The Basel III framework introduced Leverage Ratio as a non-risk-based backstop limit to supplement the
risk-based capital requirements. It aims to constrain the build-up of excess leverage in the banking sector,
with additional safeguards against model risk and measurement errors. Leverage ratio is expressed as
Tier 1 Capital against Exposure Measure, which comprises on- and off-balance sheet items. Other than
the difference in scope for consolidation and aggregation under SFRS and MAS Notice 637, there are no
material differences between total balance sheet assets (net of on-balance sheet derivative and SFT
assets) as reported in the financial statements and Exposure Measure of on-balance sheet items.

7 Macroprudential Supervisory Measures
7.1 Geographical Distribution of Credit Exposures Used in the Countercyclical Capital Buffer
To achieve the broader macroprudential goal of protecting the banking sector from periods of excess
aggregate credit growth, the Basel III standards introduced the Countercyclical Capital Buffer (CCyB)
framework. The CCyB is applied on a discretionary basis by banking supervisors in the respective
jurisdictions.
The Group's countercyclical buffer is computed as the weighted average of effective CCyB in jurisdictions
where the Group has private sector credit exposures and the geographical distribution of the private
sector credit exposures is based on where the ultimate risk of the exposure resides. Following mandatory
disclosure under MAS Notice 637 provides an overview of the Group's private sector credit exposures by
geographical breakdown.

7.2 Disclosure of G-SIB Indicators
The Basel Committee on Banking Supervision (BCBS) assesses the systemic importance of banks in a
global context and has developed an indicator-based methodology for identifying Global Systemically
Important Banks (G-SIBs). The G-SIB indicators are based on cross-jurisdictional activity, size,
interconnectedness, substitutability/financial institution infrastructure and complexity.
Although UOB is not a G-SIB, it is required under MAS Notice 637 to disclose these indicators on an annual
basis. The indicators have been prepared in accordance with the instructions issued by the BCBS. Further
details on the G-SIB indicators and assessment methodology are available at BCBS website:
http://www.bis.org/bcbs/gsib/

Total exposures differ from the total exposures disclosed under Leverage Ratio as the computation required by the
BCBS for purpose of the G-SIB assessment exercise excludes regulatory adjustments but include exposures of
insurance subsidiaries.
The Group has been disclosing the above G-SIB indicators since 31 December 2014 on an annual basis.

8 Overview of RWA
The table below lists the Group's RWA by risk type and approach, as prescribed under MAS Notice 637.
The minimum capital requirement is stated at 10.0% of RWA.
Total RWA was $6.9 billion lower quarter-on-quarter mainly due to lower asset base.

9.2 Main Sources of Differences between Regulatory Exposure Amounts and Carrying Amounts in
Financial Statements
The following table illustrates the main differences between the regulatory exposure amounts and the
carrying values in the financial statements in respect of the assets and liabilities subject to credit risk,
CCR and securitisation framework requirements.
It is not meaningful to include items subject to market risk requirements as they are based on a different
exposure measurement approach.

The total column excludes amounts subject to deduction from capital or not subject to regulatory capital
9.3 Qualitative Disclosure of Differences between Carrying Amounts in Financial Statements and
Regulatory Exposure Amounts
The main differences between accounting amounts as reported in financial statements and regulatory
exposure amounts are:
(i) off-balance sheet exposures including contingent liabilities and commitments after application of
Credit Conversion Factor
(ii) securities financing transactions counterparty exposures and potential future exposures for
derivatives, offset by netting under enforceable netting agreements
(iii) differences due to consideration of provisions
(iv) differences due to other differences, including recognition of credit risk mitigation.
The valuation process adopted by the Group is governed by the valuation, market data and valuation
adjustment policies. These policies set the methodologies and controls for the valuation of financial
assets and liabilities where mark-to-market or mark-to-model is required. These policies apply to all
assets and liabilities classified as fair value through profit and loss ("FVPL") and fair value through other
comprehensive income ("FVOCI"). The valuation processes incorporating the market rates, the
methodologies and models, including the analysis of the valuation are regularly reviewed by Group Risk
Management.
Page 25
9.3 Qualitative Disclosure of Differences between Carrying Amounts in Financial Statements and
Regulatory Exposure Amounts (cont’d)
All valuation models are independently validated by Group Risk Management and approved by the Asset
and Liabilities Committee ("ALCO"). The inputs used for valuation are independently verified by checking
against information from market sources. These are applicable to products or instruments with liquid
markets or those traded on exchanges. Where market prices are not liquid, additional techniques will be
used such as historical estimation or available proxies such as reasonableness checks.
The valuation process is further supplemented by valuation adjustments for valuation uncertainties.
Valuation adjustment methodologies and adjustments are approved by ALCO. The valuation adjustments
set aside include bid/offer adjustments, illiquidity adjustments, parameter adjustments, model
uncertainties and other day 1 valuation adjustments where applicable.
9.4 Prudent Valuation Adjustments

The table below provides the breakdown of the constituent elements of the Group’s prudent valuation
adjustment.
This prudent valuation adjustment is applicable for all assets and liabilities measured at fair value
(Marked to market or Marked to model) and for which valuation adjustments are required.
The main contributions to the prudent valuation adjustment are Day 1 break fund cost for Callable
Structured Notes, model uncertainty for Interest Rate Callables and illiquidity for equity funds.
Significant changes in valuation adjustments are in model uncertainty for interest rate structures and
unearned credit.

10 Credit Risk
10.1 General Qualitative Disclosures on Credit Risk
Please refer to UOB Annual Report 2022, Risk Management section – Credit Risk.
10.2 Credit Quality of Assets
Please refer to UOB Annual Report 2022, Risk Management section – Credit Risk and summary of
significant accounting policies under the notes to financial statements.
The table below provides an overview of the credit quality of the Group’s on- and off-balance sheet
assets.
A default on the obligor is considered to have occurred when either or both of the followings have taken
place:
• The obligor is unlikely to pay its credit obligations to the Group in full, without recourse by the bank
to actions such as realising security (if held).
• The obligor is past due more than 90 days on any credit obligation to the Group. Overdrafts will be
considered as being past due once the outstanding has breached an advised limit.

The table provides the change in defaulted exposures, the flows between non-defaulted and defaulted
exposure categories and reductions in the defaulted exposures due to write-offs.
The decrease in defaulted loans and debt securities in the second half of 2022 was mainly due to lower
inflow of new defaulted loans relative to the outflow of defaulted loans from recoveries, write-off and
returned to non-defaulted status. Other changes mainly comprise of recoveries and foreign exchange.

The following table presents changes in RWA corresponding to credit risk only (excluding CCR) over the
quarterly reporting period for each of the key drivers.
Compared to September 2022, the decrease in Group's RWA was mainly due to weakening of USD against
SGD and rating model updates.

10.14 IRBA - Backtesting of PD per portfolio (cont’d)
The following table shows the backtesting of PD of retail portfolios whose exposures are under A-IRBA
for capital computation. The retail portfolio comprises of Residential Mortgage, QRRE and Other Retail
exposures. Refer to UOB Annual Report 2022, Risk Management section – Credit Risk for key models used,
the scope of the key models as well as the percentage of RWA covered by the retail exposures.
The defaulted obligors for Other retail exposures asset sub-class (excluding exposure to small business)
for PD range 10% to <100% in the Annual Reporting Period are mostly coming from non-borrowing
accounts with overdue fees that do not meet the minimum balances. Without these accounts, there are
only 3,825 defaulted obligors in the annual reporting period and 68 new defaulted obligors in the annual
reporting period.

15 Interest Rate Risk in the Banking Book

Interest rate risk is the impact to earnings and economic value of the Group due to fluctuations in interest
rates. Interest rate exposure arises from differences in the maturity and repricing dates of assets,
liabilities and off-balance sheet items. These mismatches are actively monitored and managed as part
of the overall interest rate risk management process which is conducted in accordance with the Group’s
policies as approved by the ALCO.
The Group’s interest rate risk sensitivity is measured as changes in economic value of equity (“EVE”) or
net interest income (“NII”) based on Basel IRRBB requirements. At 100 and 200 basis points parallel
interest rate shocks, worst case results were negative $845 million and $1,998 million (FY2021: negative
$1,051 million and $2,008 million) respectively, driven mainly by the Group’s SGD position.
EVE is the present value of assets less present value of liabilities of the Group. NII is the simulated change
in the Group’s net interest income. The repricing profile of loans is generally based on the earliest possible
repricing dates, taking into account the notice period to be served to the customers. Interest rate flooring
effects according to revised MAS637 requirements are taken into consideration. Loan prepayment and
time deposit early withdrawal rates are estimated based on past statistics and trends where possible
and material. Behavioural assumptions based on historical trends are applied where appropriate. The
average repricing maturity of core non-maturity deposits is determined through empirical models taking
into account asset duration. Risk-free zero coupon curves are used for EVE discounting. Currencies are
aggregated by scenarios. There may be some differences in the assumptions across geographical
locations due to variation in local conditions.
Please refer to UOB Annual Report 2022, Risk Management section – Interest Rate Risk in the Banking
Book for more information.

16 Liquidity Coverage Ratio Disclosures
16.1 Liquidity Coverage Ratio
The Liquidity Coverage Ratio (“LCR”) ensures that a Bank has sufficient unencumbered high quality liquid
assets (“HQLA”) to survive a significant stress scenario for the next 30 days. The Group’s LCR disclosure
is as per MAS Notice 651 “Liquidity Coverage Ratio Disclosure”.
Quarterly average All Currency LCR and Singapore Dollar LCR of 147% and 255% respectively were
comfortably above the regulatory requirements of 100%. Compared to 3Q2022, increase in All Currency
LCR was mainly due to higher HQLA. Increase in SGD Currency LCR was mainly due to increase in HQLA,
partially offset by increase in outflows related to derivative exposure. The main drivers of LCR are the net
cumulative outflow driven mainly by deposit profile and the portfolio of high-quality liquid asset which
would cause some volatility on a day-to-day basis.
The Group’s HQLA composition comprised largely Level 1 HQLA which include balances with central bank
and sovereign bonds etc and the remaining in Level 2A and 2B HQLA. Deposit strategies are regularly
discussed in Group ALCO with monitoring on deposit concentration and currency mismatch etc. The
Group’s exposures to derivatives and potential collateral calls were incorporated into the LCR outflows.
Daily liquidity management is centrally managed under Global Markets-Portfolio & Liquidity
Management with regular discussion with Central Treasury and relevant Business Units. Liquidity limits
and triggers were established to limit the Group’s liquidity exposure. Balance Sheet Risk Management
oversees the liquidity risk management in the Group. Contingency funding plans are in place to identify
potential liquidity crisis using a series of early warning indicators as well as crisis escalation process and
related funding strategies.
Please refer to:

• UOB Annual Report 2022, Risk Management section – Liquidity Risk for governance of liquidity risk
management, funding strategy and liquidity risk mitigation techniques.
• UOB Annual Report 2022, Note 45 Financial Risk Management section for Balance sheet and off-
balance sheet items broken down into maturity buckets and resultant liquidity gaps.

17 Net Stable Funding Ratio Disclosures
The Net Stable Funding Ratio (“NSFR”) measures the amount of available stable funding relative to the
amount of required stable funding in a bank and promotes resilience over a longer time horizon. The bank
is required to maintain a stable funding profile in relation to the composition of their assets and off-
balance sheet activities.
The Group is subjected to NSFR standards effective January 2018. NSFR disclosure is as per MAS Notice
653 “Net Stable Funding Ratio Disclosure”. NSFR for 30 September 2022 and 31 December 2022 were 114%
and 116% respectively, above the regulatory requirement of 100%. Increase in NSFR in the 3rd quarter
was largely due to increase in retail deposits and other wholesale funding partially offset by increase in
performing loans and securities. Increase in NSFR in the 4th quarter was largely due to increase in retail
deposits partially offset by decrease in other wholesale funding. The main drivers of NSFR are the
composition and profile of deposits and capital in relation to loans. Interdependent asset and liabilities
reported include government funded loans in accordance with criteria stated in MAS Notice 652.
