The Implication
Focus on Data Available in US Defined Benefit Outsourcing BusinessHewitt administers pension benefits for over 100 clients– Generally large global organizations– Large over 20,000 employeesHewitt administers retirement benefits for about 15 million participants– Roughly breaks down as follows:
> 45% active employees, 40% retirees, 15% deferred vested
We are sitting on a uniquely large employee benefits database with informationParticular interest for longevity data because participants must be tracked ongoingDetailed demographic data (economic status: pay; geographic status: address)Information augmented by Social Security Death Index can create all data needed
Remainder of the discussion of our analysis will focus solely on US data

What We Have…
Clean Data on Most of the Lives in our DatabasesBetween 75-100 million life-years during 2000’s– Only 26 million life-years used in today’s analysis– Compare to previous US pensioner mortality studies
> RP-2000: 11 million life-yearsToday’s data from 31 Hewitt clients with a fairly broad industry mixFor all employees who have worked for employers while contracted with Hewitt– Indicative data: SSN, DOB, DOH, Status (active, disabled, terminated, retired)– Benefits data: pay, benefit level, total service, annuity option, etc.– Other data: city, state, ZIP, marital status, etc.

What We Have…(cont’d)
Clean Data on Most of the Lives in our DatabasesAnalysis today based on a subset looking at 4.9 million lives (subset of Hewitt data)– SSN, DOB, DOH, last-known ZIP (mailing checked to pensioners when they died)
> Allocating all life-years for each person based on last-knownResults are preliminary – may contain some noise from cashed-out or terminated non-vested
Venturing into “uncharted territory” in comparative analysisMost comparative longevity analyses have focused on Actual vs. ExpectedOurs is focused on a concurrent experience among separate subsets of data

Today’s Hypothesis
Consistent with past analyses of CDC and Census Bureau: Geography mattersNot only does geography matter, but that it matters down to ZIP code– Implicit that socio-economic status will provide high-correlation– More robust view of geographic dispersion than past analyses by state and metro-regionLooking at some of our outstanding issues: they don’t matter much– The primary problem is the accuracy of tracking participants that “leave”– We would expect any issues like this to persist consistently across ZIPIn the interest of credibility we focus on ZIP-3– A few words about the US postal system…

The “Red Belt”
Quite Obviously, there is a substantive region from Texas up to Great LakesForms the collective of the Great Lakes Region, Texarkana, Deep SouthRepresents where there is generally lower average income according to US Census BureauAlso, generally a low availability of services (healthcare, infrastructure, etc.)Coasts and the Northern Plains provide meaningfully better longevity

A Brief Preview of Hewitt Data versus SOA RP-2000
More than 2.5 times the number of lives than RP-2000Less reliance on auto-maker dataGenerally consistent longevity curveMatches quite nicely, but begins to degrade towards age 60 0

■ Standard tables■ No cohort
analysis■ Immature
schemes + high net interest rates= defer thinking
■ Mortality improvements analysed by cohort
■ Fading mortality improvements still the norm
■ Mortality treated as base + improvement
■ Continued future mortality improvement taken seriously
■ Mortality rating by address (initially only bulk annuities, now individuals)
■ Per person mortality rating is standard
■ Longevity risk understood, routinely priced, even traded ?

The UK Hewitt Longevity Model
Socio-economic factors do not depend on scheme, so we canpool data between many schemesdevelop a model based on the pooled data
The UK Hewitt Longevity Model isThe use of– access to substantial pooled mortality data, plus– socio-economic information we infer from addressesto improve our estimate of individual longevity
Risk…Rewarded 22
Global Risk Services
The UK Hewitt Longevity Model Member postcodes mapped to database supplied by Experian (provider of information and analytics) to estimate member's socio-economic type A socio-economic type is a grouping of individuals having similar characteristics measured in terms of wealth and lifestyle, and therefore likely to share a similar future mortality experienceFurther grouped these socio-economic types into clusters based on the combined mortality experience of Hewitt client pension schemes so that we can model them statisticallyMap of UK illustrates how individuals with different postcodes are mapped to different mortality clustersFor each of the different socio-economic clusters, determined a mortality assumption based on the collected mortality experience of Hewitt clientsWe augment the model using Government mortality statistics for regions of UK on a per member basis.
Some insurers now provide lower payments to pensioners in more affluent areas

Longevity risk components
Idiosyncratic RiskEven if you knew the “correct” mortality rate, experience will differ, particularly in small schemes.
Basis RiskHow your scheme differs from the big population, and the difficulty of measuring this and its implications.
Systematic RiskChanges in general longevity for a big population (e.g. England and Wales, or insured lives, or SAPS)

Market for longevity riskUntil recently
The main (the only?) way to reduce/remove longevity risk was via a bulk annuity type solutionCan modify future benefits but cant deal with past obligations
But NowThe Longevity swaps market existsMissing piece of risk management jigsaw?

Pricing process (scheme-specific swaps):– Deduce best-estimate of mortality for the population
> Using postcode rating factors & scheme experience

Overview of the market to dateMarket really took off in Summer 2008– Providers put specialist teams in place to target UK pension scheme trusteesBabcock and RSA deals are first swaps written directly with a UK pension scheme– Large pipeline of transactionsAlready seeing standardisation of product in the market– Have to ensure price comparisons between
providers are “like-for-like”Providers generally fall into two categories:– Investment banks
> Distribution of risk to third parties– Insurers (incl. reinsurance) companies
> Retain risk on balance sheet or reinsure
