This document provides an overview and history of liability driven investment (LDI) strategies. It discusses how LDI has evolved from initial liability immunization approaches to more sophisticated strategies that incorporate hedging to the funding ratio, time-diversified hedging, swaption strategies, and illiquid credit. The document also examines spending the risk budget between equities and interest rates hedging, how fully hedging impacts risk, and alternative hedging strategies like swaption collars. Finally, it provides context on government bond yields and how yields may still decline in countries like the UK.

Boots pension scheme shifts out of
equities and into bonds
2001
• Head of Corporate Finance, John Ralfe, recognises
pension fund liabilities are bond-like in nature
• Allocation before rebalancing: 75% equities, 20% bonds,
5% cash
• Allocation after rebalancing: 100% long-dated AAA
sterling bonds, half of which is inflation-linked
Friends Provident hedges interest rate
and inflation risk with swaps
2003
• First non-bank to implement LDI hedging strategy
• Locked in a 2.1% real yield on 30-year index linked
gilts – the real yield today is below 0%
• Conventional wisdom at the time: “equities are the
biggest source of risk to a scheme’s funding level, and
real yields cannot drop below 2%”
Lehman Brothers collapses and new
opportunities arise
2008
• Lehman Brothers collapse shows robustness of
collateralised swaps
• The gilt/swap spread inverts
• Pension funds can take advantage of spread dislocation
and hedge via gilts instead of swaps
Key events in LDI
Eurozone Debt Crisis boosts safe haven
demand for Gilts
2010-2013
• Eurozone turmoil increases the appeal of Gilts as a safe
haven asset
• Gilt real yields turn negative for the first time ever at
the longer-dated tenors
• Despite recent optimism that policymakers may be able
to contain the crisis, real yields have remained below
zero, partly due to stubbornly high market inflation rates

Hedging Strategies
10
Hedging to the Funding Ratio
• Increasing the interest rate and inflation hedge ratios to the funding ratio minimises the funding ratio impact of real rate volatility
• This means the outperformance required from the Scheme’s assets remains relatively stable if real rates change
• The “risk budget” freed up by hedging real rate exposure can be recycled in order to increase the expected return
• Insofar as a Scheme can reliably increase expected return (for example, by investing in illiquid credit), hedging up to the funding
ratio effectively “lock in” margins over the required return

Government Bond Yields in Developed Markets
Whilst the 30-year UK government bond yield has fallen significantly since 2007, there remains scope for further
declines if compared to other developed markets, with German yields over 100bps lower and Japanese yields over
170bps lower.

• Carry occurs as a result of the
market pricing in rising short-term
rates. It is easiest to explain in the
context of a receiver par swap
(say 20 years)
• In the first year, the fixed leg is
larger than the floating leg – this
is the coupon income
• If rates follow the forward curve,
then the remainder of the swap
will have negative PV, to balance
the coupon income
• However, if rates do not rise as
priced in, the remainder of the
swap will have positive PV, as it
will be a 19y swap paying the 20y
rate; this is roll-down
Carry = coupon income + roll-down

• Imagine a payment of £100m in 20
years’ time
• The PV of this cashflow is £56m
• In five years’ time, the PV is
projected to be £58m based on
forward curve discount rate of
3.73%
• However, if rates don’t change the
PV is projected to be £69m
• This means if rates are unchanged
rather than rising as is priced into
the forward rates, the value of the
cashflow will grow by 3.51% per
annum
• To win the “we expect rates to
rise” bet, rates have to rise to
exceed the forwards

Time-Diversified Hedging
• GOAL: To achieve full funding in x years; HEDGING OBJECTIVE: 100% hedged once fully funded
• SOLUTION: consider increasing hedge ratios over time
• This can be done by using fixed, periodic hedging increments combined with a trigger framework to hedge
opportunistically
• Triggers can be based on scheme-specific metrics such a funding level or required returns – agnostic regarding
catalyst for improved funding
Time-Based Hedging Combined with “Go Faster” Opportunistic Hedging

15. Private & Confidential 21st Century LDI 2 July 2013
Overview: Swaptions
15
Swaptions are options to enter into swaps
• The buyer of a receiver swaption has the right but not the obligation to enter into a swap where the option buyer
receives a fixed rate in exchange for paying a floating rate
• A payer swaption gives the buyer the right but not the obligation to enter into a swap where the option buyer
pays a fixed rate in exchange for receiving a floating rate
Receiver swaptions rise in value if swap rates fall; payer swaptions rise in value if swap rates rise
Potential uses
• Where a pension fund has exposure to falling interest rates, but expects rates to rise and therefore does not want to
lock in current levels, the purchase of a receiver swaption can offer protection against falling rates below the strike of
the swaption
• Similarly, if a pension fund has decided to hedge interest rate risk in a rising rate scenario, a premium can be earned
by selling a payer swaption with a high strike relative to current levels
• The combination of buying a low strike receiver swaption and selling a high strike payer swaption is known
as a collar
Swaption strikes can be determined in the context of the impact of interest rate moves on the required rate
of return to achieve full funding

Aim
• Increase protection
against interest rates
without locking in current
low level of rates
The Strategy – Swaption Collar
• Scheme buys a receiver swaption (offering protection against falling
rates) and sells a payer swaption (giving up some rate upside in
order to lower cost of the strategy). The strategy has two attractive
characteristics:
• PV01 profile: the interest rate sensitivity of the collar rises as
rates fall and decreases when rates rise, providing more
protection when it is needed and less when it is not
• Taking advantage of market expectations: if market
expectations of futures interest rates and volatility are met, the
value of the collar is projected to remain relatively stable over time
Outcome
• Attractive addition to
Scheme’s portfolio of
hedging assets
• The strategy has
outperformed an interest
rate swap with the
equivalent initial PV01

EMIR: Preparing for A Changing Market Environment
• European policymakers are introducing regulation
(termed “EMIR”) to reform the swaps market in
order to enhance resilience and increase
transparency
• These changes will make the swap market more
similar to the futures market, with trades cleared
through a central counterparty (CCP)
• Introduces additional rules and constraints that
pension funds should be aware of and prepare for

21. Private & Confidential 21st Century LDI 2 July 2013 21
Important information for pensions funds:
• Limited exemption from EMIR’s headline measure – the requirement to
clear OTC derivative contracts – until at least August 2015
• HOWEVER: For new trades there is no exemption from Initial Margin,
providing more incentive for these trades to be cleared early rather than
make use of the pension fund exemptions
• The other key provisions – the risk mitigation and reporting
obligations – will apply to pension funds. The EMIR obligations will take
effect on a phased basis from the beginning of 2013
Important questions for pension funds:
• Are you going to use your exemption from EMIR?
• Are your CSAs dirty or clean?
• How much free collateral do you have?
• What plans have you put in place for central
clearing?

Key Conclusions
 Ensure that real rate exposure is “right sized” to the Pension Fund
o Does the potential funding level benefit from rising (forward) rates justify the risk being
run?
 Assess the true cost of not hedging in a static rate environment
o To win the “we expect rates to rise” bet, rates have to rise to exceed the forwards
 Review the full range of hedging strategies and instruments
 Ensure that existing LDI programmes are prepared for Central Clearing
