“Given the limited amount of time series on returns and
demographic variation, and the difficulty of controlling for
all of the other factors that may affect asset values and asset

substantial weight in evaluating the potential impact of

Current Forces Affecting the Size and Current Forces Affecting the Size and Ownership of Longevity RiskOwnership of Longevity Risk
The Mosaic Today
Retirement population growing
Longevity risk moving from corporates to individuals
Cost of longevity significant and rising
Inflation could exacerbate longevity costs
Longevity extending
Credit Crunch moving longevity risk arguably to Government
The UK population of retirees (i.e. people 65+) is set to increase by 60% by 2032 from 10 million to 16 million due mainly to the ageing of the baby boom generation
Longevity continues to increase for retirees at historically high rates against largely fixed retirement / entitlement dates
The current cost of life extension in the UK is estimated at £12.5 to £24.7 billion per year
Current fiscal and monetary policy may be sowing the seeds of high inflation and expectations of inflation
Strong forces are causing corporates to close existing Defined Benefit (DB) schemes and transition to Defined Contribution / Personal Account schemes
The Credit Crunch is causing a significant increase in DB pensioner risk to move to the Pension Protection Fund (PPF)

Nothing is certain in life except death and taxes (B Franklin).
Over last 20 years, it has become clear that, while death is no less inevitable than before:– it is getting later– and its timing has become increasingly uncertain.
The problem

When British welfare state began in 1948, men could draw their state pension at 65 and expect to live until 67 and only a few lived beyond 70.
At beginning of 21st Century, British men can still draw their pension from age 65 but now live into their early 80s.
Significant proportion of women living into their late 80s.

Evident for many years that mortality rates have been evolving in apparently stochastic fashion.
Sequences do exhibit general trend, but changes have an unpredictable element:– not only from one period to next – but also over the long run.
Stochastic nature of mortality improvements
![Page 30: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/30.jpg)
31
Large number of products in life insurance and pensions have mortality as key source of risk.
Products exposed to unanticipated changes over time in mortality rates of relevant reference populations.
Eg annuity providers exposed to risk that mortality rates of pensioners will fall at faster rate than accounted for in pricing and reserving calculations:– Current pool of annuitants living 2 years longer than
anticipated

32
Annuities are commoditised products selling on basis of price, profit margins have to be kept low in order to gain market share.
If mortality assumption built into price of annuities turn out to be gross overestimate, cuts straight into profit margins of annuity providers.
Most life companies claim to lose money on annuity business.

33
Yet life annuities are mainstay of pension plans throughout the world: – they are the only instrument ever devised capable
of hedging longevity risk. Without them, pension plans will be unable to
perform their fundamental task of protecting retirees from outliving their resources for however long they live.
Real danger that they might disappear from financial scene.

Equitable Life:Embedded options in annuity contracts
became very valuable in 1990's due to combination of falling interest rates and improvements in mortality.
Problems avoided if EL could hedge exposures to:– interest-rate risk– mortality improvement risk.

Long-dated survivor bonds:Life annuity bond: coupon payments decline
in line with mortality index:– Eg based on population of 65-year olds on issue
date. As population cohort dies out, coupon
payments decline, but continue in payment until the entire cohort dies.
Eg, if after one year 1.5% of population has died out, 2nd year’s coupon payment is 98.5% of 1st year’s etc

Reference population underlying calculation of mortality rates central to both:– Viability– Liquidity of contracts.
Hedging demand from investors (eg life offices) wishing to hedge mortality exposures.
If reference population v different from investor’s specific population, then investor will be exposed to significant basis risk:– Might conclude that mortality derivative is not
worth holding.

60
Speculative demand: – depends on liquidity.
Adequate liquidity will require small number of reference populations:– Need to be chosen carefully to ensure that level of
basis risk is small for investors with hedging demands.
Demand from hedge funds:– seeking instruments that have low correlation with
existing financial instruments

After more than year, BNP Paribas longevity bond had not generated sufficient demand to be launched:– Has been withdrawn for redesign

Barriers to development in cash market

63
Reasons why BNP bond did not launch:
– design issueswhich make bond an imperfect hedge for longevity
risk
– pricing issues
– institutional issues
Barriers to development in cash market
![Page 60: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/60.jpg)
64
Small scheme will find it difficult to use bond to match its liabilities:– as variance between actual and expected mortality
will be quite large. Mortality experience of individual pension
funds and life insurers may be different from reference UK population.
Bond only provides hedge for longevity of males:– pension funds and life insurers also exposed to
significant longevity risk from females.
Design issues
![Page 61: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/61.jpg)
65
Liabilities for pension funds and life insurers give greater weight to the lives receiving larger pensions.
Further, significant differences in mortality of those receiving larger pensions compared to those receiving lower pensions.
As payments under bond effectively give equal weight to all the lives in the UK population, the already imperfect hedge provided by the longevity bond is worsened.
Design issues
![Page 62: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/62.jpg)
66
Bond only matches cashflow under level pension – while large portion of pensions paid by pension
funds and life insurers will be increasing at RPI/LPI/CPI.
Bond is progressively worse hedge for pension liabilities related to younger or older cohorts.
Design issues
![Page 63: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/63.jpg)

69
Longevity risk premium built into initial price of bond set at 20 basis points.
Given that this is first ever bond brought to market, markets have no real feeling as to how fair this figure is.
However, concern that up-front capital was too large compared with risks being hedged by bond:– longevity and interest rate risks
leaving no capital for other risks to be hedged – e.g. inflation
Pricing issues
![Page 66: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/66.jpg)
70
Issue size too small to create liquid market.Consultants reluctant to recommend it to
trustees.Fund managers do not currently have mandate
to manage longevity risk.Fund managers have not welcomed bond:
– since believe it would be closely held and they would not make money from it being traded.
Partner Re is unlikely to be perceived as being a natural holder of UK longevity risk.
Institutional issues
![Page 67: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/67.jpg)
71
Last point highly significantReflects view that key determinant of future
issue of longevity bonds is availability of sufficient reinsurance capacity.
Neither UK-based nor EU-based reinsurer willing to provide cover for BNP bond
Partner Re not prepared to offer cover above issue size of £540m.
Has been questioned whether EU’s solvency requirements render reinsurance cover within EU prohibitively expensive.
Institutional issues
![Page 68: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/68.jpg)
72
Following factors key to success of particular futures contract:
– defined as having consistently high volume of trade and open interest:
Must be large, active and liquid spot market for underlying with good price transparency:
– by far the most important factor: – indeed no futures contract has ever survived
without a spot market satisfying these conditions.
Barriers to development in futures market
![Page 69: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/69.jpg)
73
Spot prices must be sufficiently volatile to create hedging needs and speculative interest.
Relative hedging demand can be measured by level of open interest relative to volume:
– since former excludes the many speculators who do not hold overnight positions.
Low open interest to volume ratio is an indication of high liquidity :
– another sign of successful futures contract.
Barriers to development in futures market
![Page 70: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/70.jpg)
74
Underlying must be homogeneous and/or have well-defined grading system.
Market in underlying must not be heavily concentrated on either buy or sell side:
– since this can lead to price manipulation.
Futures contract must be effective in reducing risk.

75
Liquidity costs:– bid-ask spreads– execution risk:
risk of adverse price movements before trade execution
Liquidity costs in the futures contract must not be significantly higher than those operating in any existing cross-hedge futures contract.

CPI futures contract listed on US Coffee, Sugar and Cocoa Exchange in June 1985
Delisted in April 1987 with only 10,000 contracts traded.
Reasons for failure:– no inflation-linked securities market at the time. – underlying was infrequently published index. – no stable pricing relationship with other
instruments.

Futures contract on Treasury inflation-protected securities (TIPS) listed on Chicago Board of Trade in June 1997
Delisted before end of the year with only 22 contracts traded.
Reasons for failure:– TIPS had only started trading five months
before. – Only a single 10-year TIPS outstanding. – Futures contract competed with underlying for
liquidity. – Uncertainty over fate of TIPS programme.

78
CME launched CPI futures contract in February 2004 which is still trading.
Reasons for survival:– Inflation-linked securities have gained acceptance amongst
investors
– TIPS have evolved into recognised asset class.
– Well understood pricing relationships allowing for arbitrage possibilities between TIPS, fixed-interest Treasury bonds and CPI futures.
– US Treasury committed to long-term TIPS issuance.
– CPI futures do not compete directly with but rather complement TIPS and uses same inflation index.
– Contract traded on Globex electronic trading platform: automated two-sided price quotes from lead market maker.
Failure of futures contracts
![Page 75: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/75.jpg)
79
Sufficiently large, active and liquid spot market in longevity bonds must be established well before any futures market started.
Mortality index behind longevity bond must be fair estimate of true mortality and have minimal time basis risk:
– CPI index suffers from same potential problems
– so survival of CPI futures contract on CME suggests these problems can be overcome.
Important lessons for development of mortality-linked futures market
![Page 76: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/76.jpg)
80
Although mortality indices are calculated infrequently, spot prices of longevity bonds likely to exhibit high degree of volatility on account of bonds’ high duration.
Underlying mortality indices must be few in number and well-defined:
– small number of contracts helps to increase liquidity
– but also leads to contemporaneous basis risk arising from different mortality experience of population cohort
covered by mortality index and cohort relevant to hedger.
Important lessons for development of mortality-linked futures market
![Page 77: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/77.jpg)
81
Potential weak point in longevity bond market is on the supply side:
– since few natural issuers on supply side. Futures contract would be effective in reducing
aggregate risk,:– but small number of mortality indices might well leave
substantial basis risk. No reason to suppose liquidity costs in futures
contract would be any higher than for other bond futures contracts.

Existence of survivor products:
– will facilitate the development of annuities markets in the developing world
– and could well save annuities markets in the developed world from extinction.
Essential to prevent annuity providers going bust!
Conclusion
![Page 79: 4/15/2015 Strategic Asset Allocation 1 Demography, Capital Markets and Pension Risk Management session 2 Andrei Simonov](https://reader035.vdocuments.net/reader035/viewer/2022062515/56649c785503460f9492da87/html5/thumbnails/79.jpg)
83
If survivor products fail to be issued in sufficient size:
– either the state (i.e., the next generation) is forced to bail out pensioners
– or companies withdraw from pension provision– or insurance companies stop selling annuities– or pensioners risk living in extreme poverty in
old age, having spent their accumulated assets
Conclusion
