Coverage Ratio Solution Space

Dutch pension funds are in deep trouble. The average coverage ratio of many pension funds has fallen to a level well below 100% (underfunded). Some major Dutch pension funds with coverage levels around 90%, called Government to dissuade the planned pension rights cuts.

A delay in pension rights cuts seems justifiable. Key question is the reason for this requested delay. For reasons of reformulating new pension policies and ambitions, delay seems reasonable. With the intention to just 'buy time' in order to continue 'desperate hope' that the markets and low returns will recover, further delay could prove catastrophic.

Facing Reality
Pension funds have to cope with several hurricanes at the same time:
  1. Relatively low interest rates
  2. Underperforming stock market
  3. Underestimated longevity risks
  4. Need for higher confidence levels

Although low interest rates and underperforming stock markets could continue for several years, on the long term interest rates and stock markets will most likely recover, simply because economic growth imply higher returns on the long term.

Underestimating The Longevity Monster
One of the 'big' (?) surprises seems the recent development in longevity. For decades now, actuaries and researchers are structurally underestimating the effect of longevity.

Maggid's Longevity Forecast
Although longevity has been studied a lot, a decrease of the steady growth of the human lifespan in the coming decades will most likely turn out to be idle hope....

Lessons learned, we actuaries will seriously have to take into account that the linear increase of lifespan probably will continue until at least the age of 90 (Maggid forecast). This implies that we'll have to 'spice up' our mainly retrospective life expectancy models and corresponding forecasts with a healthy portion of common sense.



What about the 'risk free' discount rate?
More actu(ari)al trouble is caused by the fact of the low interest rates and sticky stock markets.
Pension funds face the substantial volatility and the low level of the so called "risk free discount rate" that drives the coverage ratio. Paradoxically we could state:

There's nothing more risky than a  'risk free' discount rate

The - artificial - low level risk free interest rate pulls down the coverage ratio of a pension fund.


At the same time it's necessary to level up the existing 97.5% confidence level of pension funds. A 97.5% confidence level implies that a pension fund will turn into default (underfunding) twice in an average person's lifespan.

Despite the fact that a 'twice in a life meltdown' is probably hard to explain to anyone, new upcoming Solvency demands for pension funds will be inevitable in order to create a level playing field on the financial market. Good governance, common sense and upcoming new regulatory initiatives will therefore certainly urge a higher pension fund confidence level like the 99,5% level in the insurance industry (Solvency II) or the 99,9% level in the banking industry (Basel II) .

Sitting Ducks
As is clear from the above image, successfully financing a pension-fund (portfolio) on the long term at the current ambition level, calls - in general - for high (unrealistic) interest rates. The 'solution space' for achieving the necessary  high coverage ratios that match the (new) capital requirements appears to be very narrow.

Therefore (there is no other way), most pension funds have to take time and redefine their (future) ambition instead of playing 'sitting ducks' and hoping for the best.

Pension Cut Delay Power

The coverage ratio (=  A / DFB = Assets / Discounted Future Benefits) is probably seen as the most important indicator of the health of a pension fund. Due to fair value accounting, low interest rates and the continuing credit crisis, the average coverage ratio dropped from 150% to  percent to 85-95% in the Netherlands. On basis of the Dutch pension law, Minister Donner and the Dutch Regulator (DNB) are now forcing some (major) pension funds to (unwillingly) cut  pension rights as from January 1, 2011.

Cutting pension rights now is premature
Although it looks certain that some major changes in the Dutch pension system will be necessary in the near future, pension cuts like proposed by DNB and the Dutch minister of Social Affairs seem inappropriate and unwise.

Board members like Dick Sluimers (APG/ABP Pension fund) argue that steering and judging a pension fund solely on basis of a 'day to day' (high volatility) coverage ratio is unprofessional. I would agree with Sluimers that a longer term average coverage ratio would be more appropriate to judge whether  a pension fund is on the right track...

Looking from a pension board captain's perspective: having just one  Coverage Ratio Indicator (CRI) on your pension dashboard is simply not enough to safely navigate your pension ship into the next harbor . Besides the day-to-day CRI and the Average long term CRI, a more dedicated indicator is needed....

Pension-Cut-Delay-Power 
Just like in case of a half full tank it's necessary to know the remaining distance and the the gas mileage of your car, in case of navigating your pension fund in heavy weather (i.c. relatively low coverage rates (70-100%)) it's important to know the the Pension-Cut-Delay-Power (PCDP ) of your pension fund.
The PCDP of a fund can be defined as the approximate maximal number of years that a fund is able to delay a required pension cut rate without ending up with a substantial (P%) higher required pension cut rate afterwards. In (an approximating*) formula:

PCDP = P * DFB / ABP
With:
P = Justifiable extra charge (in %) on top of required pension cut rate after PCDP years in case the coverage ratio is still insufficient at the same level as before.
DFB = Discounted Future Benefits (source : annual report)
ABP = Annual Benefit Payment (source : annual report)

Example: Pension Fund Dutch Metal scheme PME
Coverage Ratio ult. June 2010: CR=95%
From the annual report: DFB= €20bn, ABP= € 1bn
Set (choose) P=10%
Pension cut rate (without delay) as of 2011, suppose : PCR= 5% (=100%-95%)
*) approximating: Mature Pension Fund

Outcome:

Pension-Cut-Delay-Power = PCDP = P * DFB / ABP = 0.1*20/1 = 2 year
Pension cut rate (with 2 year delay) as of 2013: 5.5% (=5%*(1+10%))

Of course, the choice of P an PCR is up to the pension board within the limits set by the regulator.

Conclusion
As is clear from the above example, a two year delay relieves pension fund FME from the burden to put all energy, emotion and costs into an operation with minimal financial effects in the next two years, while at the same time it puts FME in the position to develop a new policy and new models to cope with the new market situation.

It's time for new pension dash board parameters like PCDC.

Actuaries are in the unique position to help pension fund members to regain control. Pick up your responsibility.

Humor: Actuarial Advice Route

Actuaries have a great job. Giving actuarial advice has become 'boardroom art'.

Although actuarial device differs as much as actuaries differ, the route of actuarial advice is - not surprisingly - mostly the same....


Keep enjoying your job as an actuary!

Pension Fund Development

Pension Funds....What originally started with well-meant intentions, has developed to one of the most complex risk management topics and will end in a nightmare if we don't change our risk management approach drastically and fast.


Pension Fund times have changed
Back in the second half of the twentieth century, Pension Funds were an excellent (HR)-instrument to stabilize employer-employee relationship and keep retention high. Since then, a lot has changed:
  • Employees became more flexible and international orientated
  • Permanent or Lifetime employment is nowadays no longer key
  • Increased social en technical complexity,  supervision, governance, etc., urge for an increasing professional approach.
  • Original Pension Fund advantages (economies of scale:cost, funding, risk) are at stake, due to the enormous (rising) costs  (administration, supervision, management [risk, asset, hedging] , funding, etc).

But there's more...  Surreptitiously, like the famous 'boiling frog', the (member) composition of a pension fond has fundamentally changed during the last decades.

Some decades ago, at the start of a Pension Fund, almost all participants where existing employees of the corresponding company (sponsor).  Today, the number of 'current employees' is often overshadowed by the number of 'pensioners' and the - until now - quiet force of  'deferred pensioners' (former employees, that left the company before retirement).

Managing Pension Fund Powers
All Pension Fund concerned parties, the three member-groups as well as the employer (sponsor), have different and sometimes opposite interests with regard to the financial policy of the Pension Fund. The tension between these parties with regard to what's best for the employer, the employees, pensioners and deferred pensioners, will therefore increase as the Pension Fund becomes more mature.

The first step to manage this tension is to redefine Pension Fund Governance in line with the changed balance of power. Skipping this governance step seems not wise, as this will undoubtedly lead to future financial claims of the concerning power-discriminated parties.

The second step is just as important.

Even with the right balanced governance in place, it will be an almost impossible task to manage a Pension Fund if the often implicit 'embedded options' between the defined member groups (including the sponsor) are not proactively recognized, defined, explicated and - above all - financially and organizational managed (settled).

Regain Pension Fund Risk Control
To regain Pension Fund Risk Control, governance principles have be transparently defined and every possible - likely or unlikely - future situation (scenario), has to be identified, described, valued, controlled and managed.

In this approach, a strong segmented, segregated or 'split up' framework, helps to keep oversight at board level and urges to define all possible 'embedded options' as clear as possible and to clear out possible sticky, fuzzy or unspoken arrangements, deals or intentions.

Pension Fund's Objectives
Of course this comprehensive operation makes only sense if the Pension Fund's objectives are (upfront) well defined and if all members agree upon those objectives. Main objectives among others are:

General (financial) PF objectives
  • Target Pension Benefit Level and volatility
  • Target Contribution Level and volatility
  • Target PF Growth Rate and volatility
  • Target Risk level and volatility
  • Target Coverage Ratio and volatility
  • Target Indexation level and volatility
  • Target Assets Returns and volatility
  • Target Cost Rates and volatility
  • Target AL-Mismatch and volatility
  • Target Mortality Rates and volatility

FMCs
In so called Financial Member-Contracts (FMCs) has to be defined exactly what the explicit financial consequences are for every Pension Fund Member, each time the actual performance of one of the objectives scores (negative or positive) out of the defined expected 'volatility range' for a certain predefined period.

On top of, these FMCs have to give a clear upfront financial answer to other general or Pension Fund specific developments. Some examples:
  • Consequences of a sponsor's default or down- or upgrade.
  • Consequences of  possible exit of substantial employers, corporate split up, outsourcing, etc.  (upfront exit conditions, restructure consequences, etc.)
  • New upfront entering conditions and principles in case of future take-overs or new employers joining the Pension Fund
  • Defining upfront catch-up indexation rules in case the target indexation levels are not met.
  • Consequences, principles, methods and guide lines that will be used in case of possible future changes in (pension) legislation, supervisory, governance or value) accounting.

Sponsor Default Risk
Last but not least, let's take a look at an interesting risk element.
One of the most risky and underestimated elements in the Pension Fund's Risk Management Framework is the 'default risk' and correspondent creditworthiness of the sponsor.

The sponsoring employer’s ability to support Pension Fund volatility by providing additional funding if required, is defined in the so called 'Employer Covenant' or 'Corporate Covenant'

Although, with regard to the obligations of the sponsor, legislation  from country to country differs strongly, the Corporate Covenant and more explicitly, the capacity of the sponsoring employer to cover (incidental) losses in the event of poor investment outcomes or the guarantee of incidental or temporary underfunding, is crucial and impacts the valuation of the Pension Fund strongly.


That this 'sponsor default risk' is not negligible, is well illustrated by the next table of Global Corporate Cumulative Average Default Rates by Standard & Poor.


Moreover the importance of the sponsor's default risk is in general essential if you take into account that the majority of companies is rated as BB an B, as is clear from the next 2003 and 2009 Corporate Ratings Distributions by S&P:



Valuing Corporate Covenant
If you're interested....In an excellent article called 'Corporate Covenant and Other Embedded Options in Pension Funds', Theo Kocken explains, how various contingent claims in a pension fund, such as the Corporate Covenant or Conditional Indexation, can be valued with the same techniques that are used to value options on stocks.

However, there's one slight problem.......

Vicious Value Circle
Future IASB proposals will  gradually move towards 'plain fair value' in case of Pension Funds. The new 2010 IASB draft versions make a first step by proposing - as AON calls it - a "third way" (between buffering and mark-to-market in combination with asset smoothing) .


As Pension Funds become more and more mature and the volatility of pension Funds is more and more reflected in the sponsoring employer's balance sheet and P&L, the question of valuing the Pension Fund becomes a kind of vicious circle.

On the one hand the value of the Pension Fund depends on the default risk and credibility of the sponsor. On the other hand the credibility and default risk of the sponsor depends strongly on the volatility of the Pension Fund.

This dependency implies that if either the sponsor or the Pension Fund gets into serious financial trouble, revaluing forces will pull the value of both institutions into a negative spiral towards a default situation, leaving the Corporate Covenant as a paper farce.


It's clear: Risk Management of Pension Funds is challenging and urges actuaries to keep eyes open.

What kind of actuary are you?

We all know plain actuarial skills are not enough to be(come) a successful professional actuary.

Time and time again we have to conclude that it takes more than average communication skills to overcome the persistent communication gap between actuaries and their audience.

In a 2008 workshop Matthias Bonikowski (Senior Manager at Milliman) presented the outcome of a German survey.

Here are the stunning results:
Proposition Actuaries' opinionNon-Actuaries' opinion
1.Actuaries are pessimists85%85%
2.Actuaries are not opportunists70% 70%
3.Actuaries communicate clearly and transparently 15% 5%
4.Actuaries think out of the box50%15%
5.Actuaries live in an ivory tower10% 50%

The Copy Paste Actuary
From the Bonikowski survey it's clear that non-actuaries (including: board managers, sales directors, product managers, coaches and headhunters) don't speak highly of actuaries.

It looks like most of the 'actuary species' are perceived as a kind of 'Copy Paste Actuary'. One who's not able to think out of the box.

We are congenital pessimists, trained to do a sort of one trick pony act. An act we can't explain or communicate, like 'normal' people seem to be able to do. 

On top of this  - just like the famous Baron Münchhausen who was unable to escape from a swamp by pulling himself up by his own hair - we actuarial poor devils seem unable to lift ourselves to the next level.

We're obviously trapped in our 'non-communication' addiction, smoke gets in our eyes and nobody around us seems capable of helping us to move from our alien planet to the world of real people, business and social life.

The non-actuaries' view in Bonikowski's survey emphasizes this image...

The non-actuaries' view
The non actuaries' view on actuaries comes down to::
- They explain complex terms as complex as possible
- Inability to make actuarial things clear to non-actuaries
- They are not able to take a bird‘s eye view
- They are missing empathy for non-actuaries

As possible reasons for this view, non-actuaries notice:
- They are isolated from decision processes…
- High expectations about actuarial knowledge – deep and broad
- Communication skills are not a part of actuarial education

As a 'solution', 7 suggestions for successful communication are developed:
  1. Point out key messages
  2. Leave out details
  3. Use more pictures and examples
  4. Explain more in “black and white”
  5. Avoid academic language/technical jargon
  6. Pick up non-actuaries earlier
  7. Define target-group specific communication rules

As we all know, these issues and solutions are not really new or surprising. Why is this issue of non-communication and 'Ivory Tower Effect' so hard to solve?

Actuaries are invisible
In 'My Opinion' of the Actuarial Review 2010, Grover Edie shows that we 'actuaries' are not in any way involved in important (political) decisions.

Important decisions that society has to take in coping with challenges as aging, longevity, health, etc.  Grover Edie explicates: 'they don’t ask us (actuaries) because we are not visible'.

My view is that the 'invisibility of  actuaries' is more or less a global issue.

Undoubtedly this theme of invisibility finds his roots in the actuary's attitude. This is well illustrated by Grover Edie's summarized reactions of actuaries on the issue:
  • “If I do good work, others will ask me for more of it.”
  • “I don’t need to advertise or to sell my work: My work speaks for itself.”
  • “I certainly don’t need to sell others on the value of my work, and if they are too stupid to know the value of what I do, that’s their problem.”

Supply and Demand
Grover Edie thinks that this underlying 'laissez-faire  attitude' is the basic problem. A problem that - in his view - can be solved with a simple sales training approach.  With all due respect...., the invisibility of actuaries has probably a deeper cause than this superficial laissez faire attitude only, that is mainly the effect of the Law of Supply and Demand.

Most actuaries had to study hard to achieve their goal of becoming a qualified actuary. Once they'd become an actuary, there was, still is and will be, more than enough well paid work. In other words: The Demand side of the market market exceeds (by far) the Supply side of the market. Why should actuaries develop a commercial sales attitude if they don't need it?

In this situation the risk that an actuary eventually becomes a 'Mirror Actuary', is not inconceivable.

A mirror actuary, one who just reflects and gives back what the environment offers him.

He looks a bit like the invisible actuary. Without a real own opinion,  the mirror actuary just reflects the financial impact and consequences of decisions taken by others.  He  acts without sincere social engagement or conviction. Hence he's unable to generate a critical positive feedback viewpoint, necessary to make what its takes, the difference.

What does it takes?
Convincing actuaries to become more visible and socially or publically involved, takes more than a professional sales approach. Actuaries have to be made conscious of why and where they are and what they really want to achieve in life.
In other words:

What kind of actuary would you (really) like to be?

In this case the answer is not a traditional one like 'Pricing Actuary', 'Pension Actuary', 'Health Actuary; or the humorous answer 'very kind'. No, the answer to this question hits our actuarial soul....

The good old actuarial horse
Would you like to be the well paid 'actuarial horse' in front of the wagon, that gets his orders from the coachman and does his calculation work every time he's being asked to do deliver some?
Or do you want to sit on the wagon, next to the coachman, discussing and advising on the best route of the wagon?


Answering these simple questions is key in solving the persisting actuarial mind setting issue.

Visibility? Select at the gate!
This invisibility issue deals with the fundamental structure of an actuary's personality.  It's not something that can be easily learned or changed during or after achieving a (long term) study. If we want visible actuaries who are socially and publically involved, we'll have to select them on that attitude at the gate, before they undertake an actuarial study. Just like we test their arithmetic talent and other mental capacities, before actuaries start their study.

The Dancing Actuary

If we don't act upon this new 'visibility insight' and keep trying to beat the famous dead horse, things will never change.

In this situation there's a tricky risk that we enjoy our salary and comfortable position so much that we suppress our critical view and potential power to change things. In which case we become totally dependable on our monthly paycheck and the opinion of our boss or manager.

In doing so, we might gradually become implicitly susceptible to extortion and eventually things will escalate.

Ultimately in this situation, we could even develop to a kind of 'dancing bear', in this case a 'Dancing Actuary'.

Try to keep your eyes open. If you feel completely 'chained' or if our environment constantly forces you to support actions or decisions you can not really account for, seek help or step out before it's too late.


The Wise Actuary
Wrapping up this warning blog about invisibility, you could get the wrong impression that black swan actuaries doe not exist at all.

Of course we know better. There are lots of wise and visible actuaries around the world and as you've made your way to the end of this blog, you'll be probably one of them....

Wise actuarial owls that want to make the difference in life and society. Actuaries who are not for sale and who know their personal limits. Actuaries that know when and where to say 'no' or 'yes'.

Actuaries that don't just want to talk about a better world, but want to act(uary) on it.

Are you that 'wise actuary', who's visible, socially active and leading society to the next level?


Test
If you want to find out if you're a wise, invisible, mirror or dancing actuary, take the next 5 minutes 15 questions test called:


Good luck with this 'actuary stress test'!

Solvency II Project Management Pitfalls

When you - just like me - wonder how Solvency (II) projects are being managed, join the club! It's crazy...., dozens of actuaries, IT professionals, finance experts, bookkeepers accountants, risk managers, project and program managers, compliance officers and a lot of other semi-solvency 'Disaster tourists' are flown in to join budget-unlimited S-II Projects.

On top of it all, nobody seems to understand each other, it's a  confusion of tongues..... 

Now that the European Parliament have finally agreed upon  the Solvency II Framework Directive in April 2009, everything should look ready for a successful S-II implementation before the end of 2012. However, nothing is farther from the truth.....

Solve(ncy) Questions in Time
The end of 2012 might seem a long way of...
While time is ticking, all kind of questions pop up like:
  • How to build an ORSA system and who owns it?
  • What's the relation between ORSA and other systems or models, like the Internal Model
  • Where do the actuarial models and systems fit in?
  • What are financial, actuarial, investing and 'managing' parameters, what distinguishes them, who owns them and who's authorised and competent to change them?
  • How to connect all IT-systems to deliver on a frequent basis what S-II reporting needs......?
  • How to build a consistent S-II IT framework, while the outcomes from QIS-5 (6,7,...) are (still) not clear and more 'Qisses' seem to come ahead?
  • Etc, etc, etc, etc^10

The Solvency Delusion
Answering the above questions is not the only challenge. A real 'Solvency Hoax' and other pitfalls seem on their way....

It appears that most of the actuarial work has been done by calculating the MCR and SCR in 'Pillar I'.

It's scaring to observe that the 'communis opinio'  now seems to be that the main part of the S-II project is completed. Project members feel relieved and the 'Solvency II Balance Sheet' seems (almost) ready!

Don't rejoice..., it's a delusion!  The main work in Pillar II (ORSA) and Pillar III (Reporting, transparency) still has to come and - at this moment - only few project managers know how to move from Pillar I to Pillar II.

Compliancy First, a pitfall?
With the Quantitative Impact Study (QIS-5) on its way (due date: October 2010) every insurer is focusing on becoming a well capitalized Solvency-II compliant financial institution.

There is nothing wrong with this compliance goal, but 'just' becoming 'solvency compliant' is a real pitfall and unfortunately not enough to survive in the years after 2010.

Risk Optimization
Sometimes, in the fever of becoming compliant, an essential part called "Risk Optimization" seems to be left out, as most managers only have an eye for 'direct capital effects' on the balance sheet and finishing 'on time', whatever the consequences......

Risk Optimization is - as we know - one of the most efficient methods to maximize company and client value. Here's a limited (check)list of possible Risk Optimization measurements:


1. Risk Avoidance
- Prevent Risk
   • Health programs
   • Health checks
   • Certification (ISO, etc)
   • Risk education programs
   • High-risk transactions
      (identify,eliminate, price)
   • Fraud detection
      (identify,eliminate, price)
   • Adverse selection
      (identify, manage, price)

- Adjust policy conditions
   • Exclude or Limit Risk  
      (type,term)
   • Restrict underwriter
      conditions
      (excess, term, etc)

- Run-off portfolios/products

2. Damage control
- Emergency Plans (tested)
- Claims Service, Repair service
- Reintegration services


3. Risk Reduction
- Diversification

- Asset Mix, ALM
- Decrease exposure term
- Risk Matching
- Decrease mismatch
   AL/Duration
- Outsourcing, Leasing

4. Risk Sharing
- Reinsurance (XL,SL,SQ)
- Securitization, Pooling
- Derivatives, Hedging
- Geographical spread
- Tax, Bonus policy

5. Risk Pricing
- Exposure rating, Experience rating
- Credibility rating, Community rating
- Risk profile rating

6. Equity financing
- IPO, Initial Public Offering
- Share sale, Share placement
- Capital injections

Solvency-II Project Oversight
Just to remind you of the enormous financial impact potential of 'Risk Optimization' and to keep your eye on a 'helicopter view level' with regard to Solvency-II projects and achievements, here's a (non-complete but hopefully helpful) visual oversight of what has to be done before the end of 2012.....

(Download big picture JPG, PDF)

Be aware that all Key Performance Indicators (KPIs), Key Risk Indicators (KRIs) and Key Control Indicators (KCIs) must be well defined and allocated. Please keep also in mind that one person’s KRI can be another’s performance indicator(KPI) and a third person’s control-effectiveness indicator.

Value Added Actions
As actuaries, we're in the position of letting 'Risk Optimization' work.
We're the 'connecting officers' in the Solvency Army, with the potential of convincing management and other professionals to take the right value added actions in time.

Don't be bluffed as an actuary, take stand in your Solvency II project and add real value to your company and its clients.

Actuarial Limit 100m Sprint

In June 2009 Professor of Statistics John Einmahl and (junior) actuary Sander Smeets, calculated the ultimate record for the 100-meter sprint. The actual World record - at that time - was set by Usain Bolt at 9.69 seconds (August 16, 2008, Beijing, China).

With help of the extreme-value theory and based on 'doping free' World Record data (observation period:1991 to June,19 2008) Smeets and Einmahl calculated the fastest time that a man would be ultimately capable of sprinting at: Limit = 9.51 seconds.

However....
As often in actuarial calculation, once your model is finally set, tested and implemented, the world changes...

Or, as a former colleague once friendly answered when I asked him if his ship (project) was still on course:


In this case, the 'model shifting event' took place in Beijing, exactly one year later, on August 16, 2009: Usain Bolt sets a new astonishing 100m World Record in 9.58 seconds !

Of course 9.58 secs is still within the scope of Smeets' and Einmahl's model limit of 9.51 seconds...

Nevertheless, as a common sense actuary, you can see coming a mile away, that this 9.51 secs-limit will not hold as a final future limit.

As is visual clear, one can at least question the validity of the 'extreme-value theory approach' in this 100m sprint case.

Math-Only Models
In this kind of projections (e.g. 100m world records) it's not enough to base estimations only on historical data. No matter how well historical data are projected into future data, things will mesh up!
Why? Because these kind of 'math-only models' fail to incorporate the changes in what's behind and what causes new 100m World Records. To develop more sensible estimates, we'll have to dive into the world of Biomechanics.

To demonstrate this, let's have a quick -amateur - look at some biomechanical data with respect to Usain Bolt's last World Record:



Let's draw a simple conclusion from this chart:


Hitting 9.50 secs seems possible


Just like Bolt stated in an interview: "I think I can go 9.50-something", appears to be realistic:
  • 0.026 secs faster by improving his reaction time to the level of his best competitors: 0.12secs, instead of  0.146secs
  • 0.060 secs faster by reaching his maximum speed (12.35 m/s) at V50 and maintaining this speed for the remaining 50 meters. 

Biomechanical explanations
On top of this, Bolt outperforms his competitors on having a higher step length and a lower step frequency. This implies there must be deeper biomechanical factors like body weight, leg strength, leg length & stiffness (etc), that need to be included in a model to develop more realistic outcomes.

Newest biomechanical research ("The biological limits to running speed are imposed from the ground up" ) shows maximum (theoretical?) speeds of 14 m/s are within reach, leading to potential World Records of around 9 secs on the long run.....

Based on this new biomechanical information output in combination with an appropriate chosen corresponding logistic model, we can now predict a more realistic ultimate World Record Estimation (WRE) in time.

Curvefitting at ZunZun with the 1968-2009 data (including Bolt's 9.58 secs record) on basis of a Weibull CDF With Offset (c), led to the next, best fit equation:

 
With: y=WRE in seconds, x=Excel date number, and:
a =  -3.81253229860548
b =  41926.0524625578
c =  8.97894916004274 (=final limit)

As we may learn more about biometrics in the near future, perhaps the ultimate 9 seconds (8.9789 seconds, more exactly) can possibly be reached faster than we currently estimate (year 2200).


Playtime
Now, just play around with (estimate) world records in this Google time series plotter:




Finally
As actuaries, what can we learn from this 'sprinting example'?
 
Well... Take a look at estimating future (2030 a.f.) mortality rates.

Just like with estimating World Records, it seems almost impossible to estimate future mortality rates just on basis of extrapolating history.

No matter the quality of the data or your model, without additional information what's behind this mortality development, future estimations seem worthless and risky.

Although more and more factors affecting retirement mortality are being analysed, (bio)genetic and medical information should be studied by actuaries and translated into output that strengthens the devlopment of new mortality estimate models.

Actuaries, leave your comfortable Qx-houses and get started!

Exceptional Longevity Predictable

A genome-wide association study (Paola Sebastiani et al) based upon 1055 centenarians, showed that Exceptional Longevity (EL)  - living 90 years or more - can be predicted with 77% accuracy!


EL Genetic Passport
This research development will have major impact on 'life insurance' and pensions. With an EL Genetic Passport in your pocket, you'll have the power to conclude with 77% certainty whether it's profitable (or not) to buy life insurance or to invest more or less in your pension fund.

Genetic Loss by GAS
To prevent major losses caused by 'adverse selection', life insurance companies and pension funds have no other choice left, than to base life insurance premium prices and pension contributions on 'genetic passport information'.

Just like it's (from a company's perspective) devastating to sell mortgages to people who cannot afford it, it's also killing to sell life annuities to people who have knowledge of getting 90 years or older with 77% certainty.

As Genetic Adverse Selection (GAS) also negatively affects current provisions and value of an insurance company or pension fund, GAS development effects should be included and estimated in actual liability calculations.

Without doubt, GAS will generate large Genetic Losses in the next decades. Perhaps GAS can be qualified as a substantial new kind of risk in Pillar I calculations.

Death by Solvency

Risk Management can be a strange and deathly game. Normally one would expect that the more the demand of Probability of Insolvency (POI) is decreased:
  • the more Prevention- , Risk-reduction- and Damage-control-measures will be taken
  • the less actual Risk and corresponding Loss will actually occur
  • the higher the resulting average yearly profit
  • the lower the resulting yearly profit volatility

This appears to be true in situations where Risk Management is hardly developed and POI-Demands are relatively modest (5%-2.5%).

Increasing POI-Demands
However, depending on the type of risk, beyond certain POI-Demands (smaller than roughly 2.5%) , the costs of Risk management measures, maintenance and capital requirements become higher than the average expected Loss-reduction, resulting in - on average - lower profits.
Of course, these extra risk management investments and capital requirements can financed by raising consumers prices, but - on balance - this will result a smaller market corresponding with a lower profitability level.

The question can be asked if this still is what we, management and consumers, intended to achieve.......?

Next, in our passion to reduce Risk to an even more extreme low level, we can get carried away completely...

Excessive POI-Demands
When POI-Demands get to levels of 1% or less, a remarkable psychological effect enters the Risk management arena.

Management perceives that the Risk-level is now actually so low that they cannot fail anymore.
In their ambitious goal to outperform the profit level of their competitors, management gets overconfident and reckless. What would you attempt to do if you knew you could not fail?

When POI-Demands are set to levels of 0.5% or less (as they are mostly now in 2010) it becomes almost impossible to beat your competitors with an approach of 'taking more risk'. Even if one would try to manage or hedge these extra risks 'best' in the market. In the long-term, the price of this risk would equal or beat the expected loss.

In this situation some managers get desperate and instead of considering things 'right', they see only one option 'left'....

WAR
'Working Around (the) Rules"

WAR, Working Around the Rules, comprises actions like:
  • Taking (extra) risks on non-measurable or non-measured financial transactions, or or 'non-obligated-reporting risks'
  • Manipulating, disguising or mitigate risk information, or risk-control reports
  • Misuse legally allowed methods and accounting principles to create legally unintended financial effects or transactions
 

It's perhaps hard to admit, but as actual developments show, we've entered the final WAR phase. Some Examples: subprime, Madoff accounting, BP-deep horizon oil failure, bank multipliers, etc, etc.

In all these examples, managers (are pushed to) become over-creative by working around the rules to deliver what they've promised: more profit.



However this approach always results in
  1. More short-term profits
  2. Less long-term profits
  3. Sudden bankruptcy in the end

This development, resembles the 2010 situation in the Insurance and Banking industry where, after each financial debacle, POI-Demands where successively decreased to a 0.5% level  and have resulted in marginal profits and a highly volatile Profits or even losses. Pension Funds (NL: 2.5% POI-Demand) appear to be the next patient the operating table.....

The situation is out of control. Nothing really seems to help anymore....



Solutions
Are there any solution to prevent this solvency meltdown process?
Yes, but that's for another blog as this one is getting too long...

Risk Symptoms Matrix

On INARM (International Network of Actuarial Risk Managers) ERM advisor Dave Ingram raises the simple question:

What must managers who are not modelers know about models?

Perhaps this question is one of the most relevant questions in Risk Management and the Actuarial profession. It's a key question that should be discussed on Board Level in every (financial) area.

Also this question is relevant in setting up and managing complex projects like Solvency II, ERM, Pension Fund Risk Management, ALM and even "In control" projects.

The answer
Now let's try to answer this intriguing question

Managers are experts in 'decision taking'. Modelers are experts in reducing and simplifying complexity to decidable parameters.

Now the Quality (Q) of a management decision (D) is defined by the equation:


[ Q(D)= Q(Manager) x Q(Modeler) ],

where Modelers are responsible for the Quality of the Input (data) of the model [Q(Input Model)] and the Quality of the modeling process itself [Q(Modeling)].

More refined, we may therefore define :

Q(D)= Q(Manager) x Q(Input Model) x Q(Modeling)

Luckily, not all Q's are independent!
Both Managers and Modelers can raise the Quality of the outcome of the Decision process by asking each other "What If" questions.

By asking WI-questions with regard to the 'Input of the Model" [Q(Input) = data, decision parameters] and examining the output, Modelers are able to raise the Quality of their (technical) Modeling by improving their technical Model [Q(Modeling)].

Moreover, decision parameters are not set in stone. So by asking WI-questions, Modelers become more aware of the Management Decision Consequences (MDCs), helping them to develop and simplify decision parameters to the most adequate, understandable and possible simplified form. Or as Albert Einstein quoted it:

"Everything should be made as simple as possible, but not simpler"

On the other hand, by asking WI-questions, Managers can study the effects of various decisions they might take in different (simulated future) circumstances (as roughly described by the Manager).

This process improves the decision taking skills of a Manager and therefore improves the Quality of the Decisions taken by Managers [Q(D)] in general. At the same time, the Modeler may use the given information from the Manager to improve his Model and (future) data as well.

Conclusion
We may conclude that the answer to the question 'What managers, who are not modelers, need to know about models' is:

Nothing, as long as Manager and Modeler intensively communicate with each other, ask WI-questions, are not afraid to admit their weakness or doubts, challenge each other and don't manipulate each other!

Perhaps an ever more tricky question to answer is:

"What must managers who are also modelers know about models?

Possibly Dave Ingram has the answer to this question....

Aftermath What happens when communication between Managers and modelers fails, is well illustrated in the Gulf of Mexico Oil Disaster, where BP CEO Tony Hayward stated before congress:
- “I simply wasn’t involved in the decision-making.”
- “Clearly an engineering judgment was taken.”

It's easy to spot failing Management-Modeler relationships by means of the next 'Management-Modeler Symptoms Matrix'.....



If you happen to be a modeler in the upper left quadrant, get out as fast as you can!

Actuarial Model World Cup 2010 Winner

In 'The Actuary June 2010', Greg Becker (actuary) and Arminder Kainth (annuities pricing analyst) present the outcome of an actuarial model they developed, to  predict the probability of a country winning the Fifa World Cup 2010.

With Brazil as a clear winner, here's the outcome:



Perhaps trading on the World Cup 2010 Bet Market can become a new interesting alternative for traditional investment categories....
Anyhow, let's hope (fingers crossed) that actuaries are right and Brazil, Germany, Italy and England all end in the semi-finals. In this case we'll ask both actuarial whiz kids to develop a new actuarial investment model to settle (for ever!) the everlasting bonds-stocks discussion....

Pension Fund Coverage Ratio Analogy

Let's compare driving your car with managing a Pension Fund. Are you ready?

You, the Car Driver

Suppose you plan a trip from New York to Washington, about 200 miles, in a tight time schedule of four hours .

You're know your car's average fuel consumption is on average about 25 miles per gallon and your dashboard computer tells you, you've got 10 gallons left in the tank.

Simple mental arithmetic shows you'll finish in Washington without any major 'out of gas'  problem if you keep your average fuel consumption above a rough 20 miles per gallon.

You tell your partner, who's next to you in the car, you're quite sure (97.5%) there's enough gas left for Washington.

Suddenly - your half way climbing a small hill - your Miles Per Gallons (MPG) Meter drops from 25 to 13.


A bit worried you take a look at the Average MPG Trip Meter on your dash board computer that shows an average of 35 miles per gallon on the first 100 miles.

You conclude there's no problem or real gas shortage issue to be expected and decide to keep checking your dashboard every 5 minutes to find out how the Average MPG develops.

Your partner, who's not familiar with driving a car or arithmetic exercises, tells you to stop at a gas station immediately and to end this silly arithmetic game.

You - quietly - explain that there's no need to go to a gas station and if you would go to a gas station, the two of you will be late on your appointment in Washington.

You tell her that you'll take no direct measures and have decided to look for a gas station if your average GPM meter shows a 25 gallons per mile.

Your partner is satisfied and you continue your trip.

Problem solved.
You, Pension Fund CEO

Suppose you run a 30 year old Pension Fund and your target is to keep a save coverage ratio of 125% on the long run.

The outcome of intense and professional Risk Modeling, ALM studies, VaR analyses, FIRM approach and other sound risk techniques, has concluded in an agreed asset mix, implicating that daily coverage ratio's may vary (97.5% CI) between  65% and 185%, corresponding with an average long term coverage ratio of 125%.

Suddenly, exactly at the Pension Funds 30th  birthday, interest rates collapse....

Your Dashboard's Daily 'Pension Fund  Coverage Ratio' (PFCR) meter shows a surprising meltdown to 65%!



All pension board members look worried. They take a look at the '5 years Average Pension Fund Coverage Rate Meter' at their Dashboard. This meter  shows a trustful 132%. You and your board conclude there is no urgent or substantial problem of  shortage on the long run.

Problem solved!, one would think. Unfortunately: No!.

At this point the Supervisor starts interfering. The Supervisor is worried and orders the Pension Board to develop a recovery plan outlining measures on how the pension fund will restore minimum funding requirements within a five-year time frame.

This Recovery Plan (RP) was not included or part of the original  strategic risk management plan as foreseen. The extra costs of executing this RP and the effects of reallocating the assets to a lower risk position, result in a lower return of the pension fund on the long run with a lower coverage ratio than the original 125% objective average.

The pension fund was forced to improve the short term (daily)  coverage ratio a little bit at the cost of substantially lowering the coverage ratio on the long run.

Congratulations!



Conclusions...
It's clear that ...
  • Pension Funds shouldn't be managed just on daily coverage ratio's, but more on 5 or 10  years average coverage ratios.

  • Demanding recovery plans after a disappointing 'two year coverage ratio' is not wise and damages the long term objectives and financial results of the pension fund.
     
  • In case of  long term (more than 5 years) failing coverage ratios, there's enough time to take measures to redefine the Pension Fund's strategy and funding policy. The same applies for interest rates, returns and other Dash Board parameters, excluding liquidity scores.
     
  • Much more than banks, Pension Funds are financial institutions with mainly long term obligations and should therefore mainly be managed, controlled and supervised by "long term" score card parameters.

Therefore, Supervisors should change their Risk Management philosophy as well as their control policy on this subject. Supervisors should redefine dash board parameters and only demand recovery plans in case of more than five year consequently failing coverage ratio's.
