Regulations and standards evolutions are driven by many factors From a difficult economic context to political and social pressures
1Context
Context
Financial institutions faced massive losses during the last crisis with dramatic impacts on the overall economy … • The subprime crisis that took place in 2007, unleashed a series of problems that threatened the financial banking system
and the whole economy as well
• From a real estate crisis, to a financial crisis, to an overall economy crisis, this difficult period revealed shortcomings inidentifying, hedging and managing risks in the banking system
• The causes of this turbulence were of different natures A confidence crisis Liquidity and funding issues Volatility and unpredictability of market parameters High level of correlation between financial institutions and systemic risks Significant increase in OTC derivative transaction volumes
Raison d’être of
Standards
A reaction to shortcomings revealed during the crisis • Some regulations evolved, others were created in order to cover the shortcomings in risk management revealed during
the crisis• For example, Basel III came as a reaction to a bad coverage and understanding of Counterparty Credit Risk and liquidity
management
A Changing environment • Today’s economic environment is on perpetual motion from a legislative framework point of view (geographically,
between the EU and the US) and from a convergence and homogenization between regulation and standards (regulatoryand accounting standards)
Political & Social pressure• One of the obvious raison d’être of regulations is the political and social pressure, in order to regulate accurately the
banking system and to avoid abuses and excesses
Since the last decade, the regulation and the monitoring of the banking system have been subject to sharper focus

Latest updates and evolutions of Basel III – liquidity ratios
Latest updates• On the 7th of January 2013, the Basel committee published the latest evolutions
and decisions taken towards the definition of the Liquidity Coverage Ratio• What changes in this new version ?
The timetable and calendar of application The perimeter of instruments taken into account within the liquidity buffer Revision of outflow rates Drawdown rates on off-balance sheet exposure Revision of inflow rates
LCR =Liquidity buffer
Outflows – min( Inflows ; 75%)
• The following instruments cannow be taken into accountwithin the liquidity buffer,capped at 15% from the totalbuffer
Corporate investmentgrade bonds with a50% haircut
Some equities in majorstock indices
RMBS with a minimumgrade of AA with a 25%haircut
• Liquidity lines with CentralBanks are under discussion,whether to take them intoaccount or not
Liquidity buffer
• Outflow rate on non-operational deposits is reducedto 40% from 75% initially
• Drawdown rates on liquiditylines is reduced to 30% from100% initially
• Drawdown rate on liquidity andcredit lines with entitiessubmitted to the LCR isreduced to 40% from 100%initially

Objective Description
Limits of Basel I• The main input for Cooke solvency ratio is total
amount of granted loans• Asset weightings - enabling to consider the
weighted risk - did not reflect the borrower's realcreditworthiness
• In addition, the maturities of contracts were notconsidered either
• Finally risk mitigation / hedging techniques (CDS,securitizations, collateral & netting agreements) andoperational risk were also not treated within Basel I
Objectives of Basel II• Basel II standards propose an approach allowing to
consider the creditworthiness of the borrower viaan internal rating system
• In addition, they enhance market risk measurement(e.g. through the VaR) and define terms for treatingoperational risk
• Within Basel II, McDonough ratio – replacing Cookeratio - considers credit, market & operational risksand aims to strengthen capital requirements
• Moreover, within Pillar II, financial institutions shallalso assess and ensure the adequacy of regulatorycapital with economic capital - which reflects thereal activity of a specific financial institution
• Finally, financial reporting & communication aremandatory within Pillar III, in order to enhancetransparency among the banking system
Credit Risk• Basel II proposes an Advanced Approach to capture
default risk based on an internal rating system• A probability of default (PD) is calculated for each
counterparty through various techniques (statisticalapproach, expert judgment etc...) over a one-year-horizon
• Exposure At Default (EAD) is calculated and definedas the asset's book value
• Finally, Default Recovery Rates (RR) are determinedvia different techniques (statistical approach,historical approach…)
• For each asset, a risk weight is determined from thecombination of PD, LGD and EAD
• Maturities impact and rating migration risk is takeninto account via an adjustment coefficient
Counterparty Credit Risk• Basel II defines techniques for determining
exposures on derivatives and securities financingtransactions (repo, securities lending / borrowing)
• It also defines terms for taking into account riskmitigation techniques (collateral, nettingagreements, etc…)
Operational risk• Operational risk is also considered and evaluation
techniques are presented (AMA, BIA, STD..)
Market Risk• It is about capturing risks coming from market
factors volatility (FX rates, interest rates, creditspreads)

Objective Description
Motives of Basel 2.5• This reform is considered as an enhancement of
Basel 2 and began in 2005• Following the 2007-08 financial crisis, its scope has
been widened• In fact, during the 2007 crisis, in a context of
extreme volatility of market variables, VaR modelsintroduced in Basel II failed to capture such extremesituations
• As a reminder these models estimate potentiallosses of a portfolio via historical scenarios formarket variables
Objectives of Basel 2.5• Following the financial crisis, where situations of
extreme stress and volatility were observed, Basel2.5 has been issued to capture accurately suchextreme events (which were not taken into accountwithin historical scenarios)
• The scope of Basel 2.5 encompasses exclusivelycredit, market and concentration risks
• Its purpose is to meet the following objectives> Capture Losses related to extreme events> Capture Losses due to default and rating
migration> Treat securitizations & re-securitizations> Take into account correlations between
assets of the trading book
Credit Risk (Standardized Approach)• Securitizations & Re-securitizations are treated as
held into the banking book. They are thereforeprocessed in the framework of credit risk policy.This aims to avoid the arbitrage between thetrading and the banking book
• While determining the exposure on securitization,both balance sheet and off-balance sheetcommitments are considered
• New weighting factors must apply on securitizationinstruments
Market Risk (Internal model approach)• Stressed VaR - It is a new VaR model based on
stressed scenarios for market variables in the intentto capture situations of extreme volatility. This VaRis additional to the classical VaR
• Incremental Risk Charge (IRC) - allows to capturedefault and rating migration risks via a VaR (99% ; 1year) model. It is additional to the market riskcapital charge introduced in Basel 2. It is aboutintroducing a “credit risk” based approach forinstruments held in the trading book
• Comprehensive Risk Measure (CRM) - allows tomeasure both the correlation between instrumentsof a portfolio and the volatility as well
Pillar 2 / Pillar 3• Basel 2.5 defines a Compensation Policy for market
participants (deferred bonus distribution,…)• It also handles the management of concentration
risk and enhances financial communication

Objective Description
Motives of Basel 3• This reform is basically a response to what has been
observed during the 2007 crisis where capitalreserves failed to absorb recorded losses
• Furthermore the 2007 crisis uncovered manyloopholes. For instance, it was noticed that certainrisks were not covered or considered in the previousstandards or by internal risk management models
Objectives of Basel 3• Basel 3 main purpose is to cover shortcomings
identified during the 2007 crisis in terms of riskmanagement
• Basel 3 proposes amendments for existingstandards but also defines a set of new rules andconsequently widens the scope of issues covered byprudential standards
• More precisely, it enables to meet the followingobjectives
> Enhance the quality and the quantity ofcapital reserves
> Regulate the leverage effect by introducinga leverage ratio whose purpose is toincrease capital reserves or reduce assetsvolumes
> Capture systemic risk and the risk ofcontagion from a financial crisis to anoverall economy crisis
> Enhance Counterparty Credit Riskmanagement and frame a policy forliquidity risk
Enhance the capital structure• Tier 3 is removed and Tier 1 is split into Tier 1 and
Core Tier 1. CET 1 increases to 4,5% from 2%previously
• Some securities previously eligible for Tier 1, will bedowngraded to Tier 2
• The Solvency Ratio must be greater than 10,5% (vs.8% previously
Leverage Ratio• It is defined as the ratio between Tier 1 Capital and
non-weighted exposures (on- & off-balance sheet)• This ratio must be greater or equal to 3%. It
whether increases Tier 1 capital reserves or reducesthe size of the balance sheet
Systemic Risk• Correlation coefficient is increased by 25% for
financial institutions to reflect theirinterdependency and the risk of contagion
• Constitution of a Conservation Buffer thatrepresents 2,5% of the Solvency ratio. It is a CET 1extra cushion
• Constitution of a Countercyclical buffer duringperiod of growth, used to absorb losses during adownturn cycle. It is a CET 1 extra cushion
• Calculation of exposures with CCP
Counterparty Credit Risk / liquidity Risk• CVA calculation to capture MtM Losses due to credit
spreads volatility and to consider WWR through thecalculation of stressed EPE
• Implementation of 2 Liquidity Ratios (ST & LT)

Regulation summary Description
Classification & Measurement• IFRS 9 paragraph 3:5 - The ED proposes two primary
measurement categories for financial instruments.A financial asset or financial liability would bemeasured at amortised cost if two conditions aremet: the instrument has basic loan features and theinstrument is managed on a contractual yield basis
• A financial asset or financial liability that does notmeet both conditions would be measured at fairvalue
Impairment rules• IFRS 9 IN5 (b) - the proposed impairment approach
generally would result in earlier recognition ofcredit losses than the incurred loss impairmentmodel in IAS 39 (ie avoid the systematic biastowards late recognition of credit losses). In otherwords, the requirement for an observable loss eventto have occurred before considering the effect ofcredit losses would be removed
• IFRS 9 IN10 - The IASB has continued to stress theimportance of reflecting the relationship betweenthe pricing of financial assets and expected creditlosses
• IFRS 9 IN 11 - The FASB concluded, jointly with theIASB, that an entity should, along with consideringhistorical data and current economic conditions,consider reasonable and supportable forecasts offuture events and economic conditions fordeveloping the entity’s estimate of expected creditlosses
Motivations• Before the last financial crisis, impairments on
assets valued using the amortized cost method,were calculated using the “incurred loss” method
• This means that impairments exist only if a lossevent occurs
• During the financial crisis, a huge number of lossevents occurred, and the impairment stockincreased drastically, which meant that reservesalready in place failed to absorb current losses
Objectives• The incurred loss model suffered from shortcomings
which led to propose another model• In fact, it recognizes expected losses lately waiting
for a credit event to occur. It also overestimatedinterest income because interest rates didn’tinclude a risk premium related to the creditworthiness of counterparties
• Consequently, impairment under IFRS 9 are to becomputed using an Expected Loss model, whichmeans that reserves are to be built up before acredit event occurs
• The main objectives of this model are Building up reserves to absorb losses if a
downturn in the economy occurs(countercyclical effect)
Converge with Basel II definition ofexpected loss

IFRS 13 provides more precision on fair value definition…but banks concerns are more focused on CVA / DVA computation
2Principles & objectives of the Standards
IFRS 9
IFRS 13

Regulation summary Description
Fair value hierarchy• IFRS 13:72 - The hierarchy gives the highest priority
to quoted prices in active markets and the lowestpriority to unobservable inputs
Fair value definition• IFRS 13:Appendix A - The price that would be
received to sell an asset or paid to transfer a liabilityin an orderly transaction between marketparticipants at the measurement date (i.e exit price)
Valuation techniques• IFRS 13:62
market approach – uses prices andinformation generated by markettransactions
cost approach – current replacement cost income approach – discounted cashflows
CVA / DVA impairment• IAS 39.AG67 - Fair value reflects the credit quality of
the instrument• IAS 39.AG28 (b) - An appropriate technique for
estimating the fair value of a particular financialinstrument would incorporate credit risk
• IFRS 13.42 - The fair value of a liability reflects non-performance risk. Non-performance risk includes,but may not be limited ton an entity’s own creditrisk
Motivations• One of the major motivations of IFRS 13 is the
convergence of accounting standards, byestablishing a set of accounting rules that will beused generally and by reducing the gap between USGAAP and IFRS
• IFRS 13 was designed in order to give one cleardefinition of fair value measurement as well asenhancing clarity by standardizing elements ofreporting and valuation techniques
• Moreover, during the crisis of 2007, MtM losseswere of phenomenal amounts which led to defineclearly fair value and how it must be measured
Objectives• IFRS 13 establishes a single framework for all fair
value measurement but does not change when fairvalue must apply
• But rather describes how to measure fair value• Moreover, IFRS 13 clearly stipulates that fair value
must reflect losses due to counterparty credit risk(CVA) as well as gains due to an entity’s own creditrisk (DVA)
• Nonetheless, IFRS 13 doesn’t define how CVA andDVA are to be computing which means thatcalculation methodology are one of the major issuesfor banks under IFRS 13

Leverage Ratio – Basel III Liquidity Ratios – Basel III
Central Counterparty Clearing House – Basel III
• EPE / Stressed EPE – One of the mainchallenges for CVA computation underBasel III (Advanced approach) is to builtup pricing models and scenariogenerators
• Hedging CVA & interactions with CVAdesks – It is important that processesfor computing CVA capitalrequirements, CVA impairment andCVA desks must be optimized
• Requires a highcomputingcapacity withoptimized modelsfor MT simulations
• Requires a goodunderstanding ofprocesses as wellas all CVAcomponents
• Identification of transactions with CCP– Within Basel II, transactions with CCPhad an EAD = 0, which meant thatthese transactions were not identifiedseparately
• Margin calls and collateralmanagement – With EMIR regulation,the volume of transaction with CCP willincreases significantly
• Default Fund – Basel III defines capitalrequirements for balance and off-balance sheet default funds
• Requires highgranularity within ITsystems & a newmethodology forEAD calculus
• Requires optimizedprocesses with BOcollateral manag.unit
• Requires optimizedprocesses with Risk& Financial functions
• Repos and derivatives treatment –One of the inputs to the ratio is repotransactions with a netting betweencash leg and securities leg
• Reconciliation between risk andfinance function – The inputs to theleverage ratio are of 2 natures : Risk &finance. Risk inputs are repos andderivatives treatment. Finance inputsare capital information
• Requires the capacityof identifying to eachbalance sheetexposure, its off-balance sheet leg
• Requires optimizedprocesses with Risk& Financial functions
• Liquidity buffer – is constituted of cash,central bank reserves, liquid securitiesetc…
• Identification of encumbered assets –Assets used as collateral (forsecuritization for instance) must beidentified and treated differently interms of liquidity within the NSFR

Banks will face great challenges in putting in place regulations… with an impact on models and methods
CVA Impairment – IFRS 13 Expected Loss model - IFRS 9
• CVA / DVA methodology – One of the main challenges for CVAimpairment is putting in place a methodology (knowing that it isnot specified in IFRS rules)
• Benchmark of methodologies that can be used
• Expected Loss methodology – The Expected Loss within IFRS 9 hasthe same definition as the expected loss within Basel II. The challengefor banks is to calibrate the EL correctly to avoid overlap with the ULwithin Basel II. This point will be detailed in part n°5

• CVA = PD x LDG x EAD• PD - In priority, consider observable credit spreads. If not
available, use regulatory 1-year PD, and determine PD tillmaturity using incremental PD formula
• EAD In a standardized method, use the Current
Exposure Method (MtM + Add-on) usingregulatory add-on factors
In an advanced approach, use EPE models• LGD - In priority, consider observable LGD (rating agencies,
etc…). If not available, use regulatory LGD
• CVA = Present Value 1 (Risk Free) – Present Value 2 (+ riskpremium)
• Cashflows are discounted using zero-coupon curves, thenzero-coupon + credit spreads
• CVA = EAD x (credit spread x duration) x LGD• CVA is computed as a function of credit spread

Maturity adjustment
coefficient, function
of PD
• The maturity adjustment coefficient introduced within Basel IIhas a dual purpose
The longer the maturity is, the higher the risk is It is a function of PD, and captures rating migrations
• The purpose of CVA under Basel III is to capture losses due torating volatility and migration
Analysis of the b(PD) term
It is an additional capitalrequirement for ratingmigrations. Rating Migrationsare more likely to happen forlower PD and highermaturities
• For Basel III-CVA under the IRB approach, the maturity adjustmentcoefficient may be set to 1 (which means capturing default-onlyrisk) if the bank can demonstrate that rating migration and risks arecorrectly and efficiently captured in the specific VaR model

• CVA under IFRS 13 covers expected losses on derivativesand repos style transactions due to counterparty default

MtM Loss due to rating volatility
There are two main axes for optimization : Methodologyand perimeter of application• Methodology & inputs – Measuring CVA under IFRS as an Expected
Loss model will allow to capitalize on Basel II parameters (PD, LGD,EAD) and use them as inputs to the model. These inputs are alsoused for CVA computation under Basel III
• Perimeter of application – CVA under Basel III and IFRS 13 arecomputed on all non-defaulted derivatives and repo styletransactions. One the perimeter is identified, regulatory EAD can beused for IFRS 13 purposes, after reconciliating MtM used forregulatory purposes and MtM used for accounting purposes
Methodology& inputs
