ICA and ICG
  • The Individual Capital Assessment (ICA) is a
    firms own assessment of its capital
    requirements, given its risk exposures
  • Self-assessment introduced with effect from
    31.12.2004 (GENPRU 2.1.6)
  • Individual Capital Guidance (ICG) is any guidance
    provided by the FSA on the amount or nature of
    capital resources to be held by the firm under
    SUP 9.3 (eg. as a result of review of the ICA)
  • ICG is not published (private between firm and
    FSA)

4
ICAS - Motivation
  • To provide firms with an incentive to improve
    risk management
  • Past weaknesses eg. provision for guarantees
  • Limited engagement with operational risk
  • Reinforce responsibililty of senior management to
    manage capital resources of the firm in line with
    its risk
  • No longer acceptable to rely on compliance with
    regulatory minimum requirements
  • Firms should consider their own risk exposures
    and form their own views on the amount and
    quality of capital they should hold
  • To help inform FSAs own view of overall capital
    adequacy of firm
  • Together with wider supervisory view, helps in
    providing Individual Capital Guidance

ICA
  • Internal risk based capital assessment
  • Considers all major risks explicitly
  • Market
  • Credit
  • Insurance (mortality/longevity, morbidity,
    persistency, expense)
  • Liquidity
  • Group
  • Operational
  • Can allow for exercise of Management Actions
  • Responsibility of Board (advised by Actuarial
    Function Holder)
  • Responsibility to notify FSA if ICA has fallen,
    or is expected to fall, below ICG (SUP App 2.7)

6
FSA Regulations
  • No detailed rules
  • Three main ICAS principles high level guidance
    on their implementation (INSPRU 7.1)
  • Supplemented by Guidance on ICAS produced by ABI
    other trade bodies
  • BAS Guidance (GN46/GN47)
  • Indication of FSAs approach to Principles Based
    Regulation ?

7
ICA Key challenges
  • Absence of detailed rules
  • Deciding what approach to follow
  • Model calibration
  • Data limitations
  • Risk aggregation/correlations/non-linearity
  • Subjectiveness/application of judgement
  • Engaging senior management
  • ICG Process

8
What approach to follow?
  • Instantaneous stress, simulations of t1 balance
    sheet or run off?
  • Measurement Value at Risk or Tail VaR ?
  • Confidence level/time horizon
  • Aggregation of risk (correlation matrix,
    copulas)
  • ICG set using Value at Risk approach at 99.5
    confidence level over 1 year time horizon

9
What approach to follow?
  • Most companies built on existing RBS or Economic
    Capital models
  • Capital requirements for individual risks
    determined by applying instantaneous shocks to
    economic balance sheets (VaR approach)
  • Analogous to RCM stress for RBS
  • Shocks calibrated to be equivalent to a 0.5th
    percentile event over a one year time horizon
  • Allowance made for management actions taken to
    mitigate impact
  • Overall capital requirement calculated by
    applying correlation matrix to individual capital
    reqs
  • Capital ??i,j KiKj 1/2

(?i,j are correlations between risk factors, Ki
capital reqs)

11
Choice of model
  • Investment risks normal, lognormal, percentile
    from from ESG output, Jarrow-Lando-Turnbull for
    credit spreads,etc ...
  • Is model tractable?
  • How well does model fit historic data?
  • Insurance risk
  • Analysis of A/E may help in setting
    mis-estimation stress
  • Trend risk more difficult (eg. future mortality
    improvements of Long cohort with floor,
    internal cause of death models)
  • Operational risk new territory for many
    insurers

12
Data limitations
  • Lack of data trying to calibrate a 1 in 200
    year event!!
  • Relevance of data
  • Most acute for non-investment risks
  • Example - pandemic event (Avian flu H5N1)
  • How relevant are past pandemics?
  • 1918/19 Spanish Flu (40m deaths)
  • 1957/58 Asian Flu (2m deaths)
  • 1968/1969 Hong Kong Flu (1m deaths)
  • What could 1 in 200 year event look like?
  • Re-assortment of H5N1 genes could result in
    extremely virulent strain capable of transmission
    between humans
  • Greater infection rates due to urbanisation,
    increase in travel
  • Availability of antiviral drugs, medical advances
  • Improved monitoring, transmission containment
    measures
  • Different impact on different age groups?
  • Need to apply judgement

13
Model calibration
  • Even where data exists, how relevant is it?
  • Example choice of time period for investment
    data
  • Should periods like World Wars be excluded?
  • Should we include periods of high UK inflation?
  • Shorter period gt more volatile stresses more
    volatile ICA result, but more relevant to current
    market conditions
  • Longer period gt more stable stresses ICA
    result, but possibly less relevance to current
    market conditions
  • Question of philosophy/judgement

14
Inconsistency of data
  • Example Correlation between Equity Returns and
    Fixed Interest Returns
  • Positive for most of 20th Century
  • Including during 1929 Wall Street Crash, 1973/74
    Middle East Oil Crisis, 1987 Black Monday,
    1997/1998 Russian debt/LTCM crisis, 1990s
    recession in Japan
  • Negative in period following bursting of dotcom
    bubble in 2001/2002
  • What is an appropriate stressed correlation
    assumption?

15
Risk aggregation/correlations
  • Diversification benefit often very large item on
    ICA balance sheet
  • Most companies use correlation matrix approach
  • Judgement in setting stressed correlations
  • Correlation matrix approach doesnt pick up
    non-linear interactions between risks
  • Non-linearity could lead to understatement (or
    overstatement) of ICA
  • Need to investigate make adjustments if
    appropriate

16
Non-linearity
  • Scenario testing approach
  • Combined market scenarios calibrated to 99.5/one
    year confidence level using results of individual
    market stresses
  • Medium bang approach
  • Calculates adjustment factor by comparing result
    of
  • Running individual stresses at lower confidence
    level (eg. 93), and
  • Combined scenario where all happen simultaneously
  • Killer scenario
  • Similar to medium bang but prob of stresses
    weighted towards most significant risk exposures

17
Engaging senior management
  • Time constraints
  • Initial education overhead
  • Ongoing commitment to review exercise judgement
  • Provides a common language for management of risk
    across business

ICG Process How was it for you?
  • More resource intensive than expected
  • Open discussions
  • Drip-feed of follow-up questions
  • FSA views evolved during process
  • Outcome no surprise

20
ICG
  • First round now almost complete second round
    begun
  • ICG provided to
  • 53 life companies (95 of market by liabilities)
  • 102 general insurers (97 of market by net
    premium income)
  • Average ICG (ICG issued in 2006 Jan 2007)
  • General insurers 110 of ICA
  • Life insurers 114 of ICA (range 100 to 170
    a few outliers)

ICG
  • Main reasons for ICG add-ons
  • Life
  • Aggregation (diversification, stressed
    correlations non-linearity)
  • Operational risk
  • General
  • Operational risk
  • Lack of evidence to support choice of assumptions

Asking the impossible?
25
Quantifying Operational Risk
  • Op Risk risk of loss from inadequate or failed
    internal processes, people and systems, or from
    external events
  • Who cares?
  • Could adopt simple factor-based approach (eg x
    of assets)
  • Motivation for more advanced approach
  • Internal
  • Better understanding of risk
  • Effectiveness of controls
  • Incentivise risk management as controls lead to
    lower capital
  • External
  • FSA
  • Emerging best practice
  • Ratings agencies?

26
Cant get there from here?
  • How to get from this
  • ...to this?

Capital requirement x Assets
99.5
0.5
Capital requirement
27
Main stages of the journey
  • Design a new process
  • Identify the key risks
  • Collect data (actual loss data expert
    testimony)
  • Create loss distributions
  • Build use a Monte Carlo model
  • Identify required capital at 99.5th percentile

28
Data the key issue
  • Data is scanty even for market risks
  • Much less available for OR
  • Internal loss data inadequate by definition
  • External loss data useful, but not enough
  • Expert judgement subjective but vital to plug
    gaps
  • Use everything available, but biggest challenge
    is to harness the expert knowledge in the
    company.

29
Key risk identification
  • Filtering process trying to identify the most
    significant risks
  • Focus on loss events not strategic risks
  • For risk management purposes the whole chain of
    causality is important.
  • For the modelling we focused on the immediate
    prior cause (eg poor complaints handling)
  • This is where the financial loss actually occurs
  • More concrete and therefore easier for people to
    come up with numbers
  • Identified collection of front line risks eg
  • Business interruption
  • Poor complaints handling
  • Legal risk
  • Fraud
  • Pandemic Flu

Failure to set strategic direction
Low morale
High staff turnover
Staff shortage
Poor complaints handling
30
Scenario workshops
  • Series of workshops set up involving risk owners
    / experts in each field
  • Tasked with creating loss distributions for each
    of the front line risks
  • Facilitation challenge strike balance between
  • Motivation (this affects actual capital perhaps
    SP rating)
  • Terror (this affects actual capital/rating!!)
  • Asking the impossible?
  • at least 3 points on a loss distribution for each
    risk most likely, severe, extreme events
  • need both impact and probability for each point
  • use experience of actual losses existing
    controls
  • brainstorming, no wrong answers, what if
    analysis
  • knowledge, enthusiasm, creativity

31
Example of a loss distribution
32
Monte Carlo modelling - best way to combine the
loss distributions
  • Inputs to model
  • Loss distributions
  • Correlation assumptions
  • Each simulation produces an aggregate loss across
    all risks
  • Run 10,000 simulations
  • Now have aggregate loss distribution
  • Capital requirement 99.5th percentile loss

Note can allow for correlations between risks
33
  • Useful to have drill down facility can examine
    component loss events for any simulation
  • Management challenge - is this scenario plausible?

34
Embedding
  • Such a process should become a core part of risk
    management
  • Rapid development in recent months will want to
    go round loop again this year to ensure robust
  • Management review of data modelling results
  • Challenge / feedback / refinements
  • Not an exact science a means to an end
  • Improving understanding of the key risk drivers
  • Help to formulate articulate risk appetite
  • Connecting up operational and financial areas of
    the business
  • Eg value of good insurance policies gt no changes
    should be made without considering capital
    implications.
  • Improved collaboration across functions.
  • Helping you to understand
  • for some risks holding capital is unavoidable
  • for others better solution is strengthen controls
  • tradeoffs between the cost of improving controls
    and the savings in capital cf cost/benefit of
    hedging market risk

35
Are we there yet?
  • Journey will continue
  • Can always improve on the modelling, but the data
    is a bigger challenge
  • Not impossible!
  • Scope for creativity

36
Final Destination Reached?
37
Using the ICA (Embedding)
  • ICA is more than just a number, its about good
    risk management.
  • ICA is superior to the old Pillar 1
    calculations as it measures the capital required
    based on the risks inherent in a companys
    business.
  • But the measurement of risk is only one part of a
    strong risk management structure.
  • The first wave of reviews largely focused on the
    measurement of risk

38
Using the ICA (Embedding)
  • . However, the second wave of reviews will be
    different.
  • we are looking at how best to add real value
    to the next round of reviews of ICAs...scope
    for added value from taking a more qualitative
    approach challenging firms on how they are
    using their ICA in practice to make better
    business decisions and improve risk and general
    governance.
  • Sarah Wilson, Director Retail Firms Division FSA
    (6th March 2007)
  • So the bar is being raised by the FSA.

39
What have companies done so far?
  • Strategic Decisions
  • Review of risk appetite
  • Information gleaned from ICA used to develop
    hedging strategies.
  • Revised reinsurance arrangements.
  • De-risking asset mix.
  • Operational decisions
  • Using in capital projection plans.
  • Some companies have sought to embed economic
    capital into pricing.
  • Used in the determination of investment policy

40
Regulations and Guidance
  • FSA launched its new ICA Principles during 2006.
  • Objective was to give greater clarity over FSAs
    expectations and help deliver consistent capital
    guidance across the industry.
  • 3 sub-principles (rules), which can be summarised
    as
  • Assessment must reflect the firms actual risk
    profile.
  • Comparability to a 99.5 / 1 year probability
    that the value of the firms assets will exceed
    the value of their liabilities.
  • Model methodology documenting the firms
    reasoning and judgement underlying the ICA
    assessment.
  • The ABI also launched its A Guide to the ICA
    Process for Insurers, which aimed to provide
    advice to companies on how to interpret guidance.

41
Possible Future Developments
  • ICA is still in its relative infancy and emerging
    best practice will continue to develop.
  • Methodology and assumption changes are becoming
    less of a priority
  • Short term challenges include
  • (Refining) Projections of the ICA
  • Developing robust analysis of change
  • Enhancing operational risk methodology
  • Developing scenarios
  • More attention is planned to be given by the
    industry to improving integration and use of the
    ICA in the business

42
Possible Future Developments
  • Future developments are likely to be influenced
    by Solvency II, as UK Insurers are likely to want
    to go down the internal model route.
  • To have internal model approved for solvency II,
    there are three tests to be passed. They are
  • Statistical Quality Test
  • Calibration Test
  • Use Test
  • FSA to suggested to date that the hurdle to be
    passed for these is much higher than the UK
    industry has had to achieve so far under the ICAS
    regime.

43
Final Destination Reached?
  • Still work to be done in embedding ICA by the
    industry
  • Work required by industry to get internal model
    approval for Solvency II
  • So the journey not yet complete.

44
What does this mean for actuaries?
  • ICA is principles based not rules based.
  • Requires a lot more judgement which have to be
    justified to Board (ultimate ownership).
  • Quantifying the risk requires detailed modelling,
    but also understanding of the weaknesses of the
    model.
  • Need knowledge of all the business
  • Cannot be a one department number. Need to
    listen to the business to ensure that the risks
    are considered.
  • Need to explain what the number means in business
    terms how does this number relate to risk in
    the business.
  • Therefore, actuaries are very well placed for
    ICA/Solvency II with skills and knowledge we can
    bring to the table.
  • This provides interest work and enhances
    marketability.
  • Opportunities in Europe as they address Solvency
    II ?
  • However, no room for complacency other skilled
    professionals in the risk assessment field.
