Reaction of schemes looking to de-risk
• How does this impact us?
– In payment : RPI generally hard-coded
– In deferment : reference to statutory revaluation
• ETVs and PIE exercises put on hold
• Buy-in / Buy-out decisions delayed

Hedge with RPI
• 1 in 200 year test
• Basket of goods
• Methodology
• Political influence
• LPI (0,5) using CPI
• Annual vs compound

Hedge with CPI
16© 2010 The Actuarial Profession www.actuaries.org.uk
• Investment Bank A : CPI vs RPI = 0.1%
• Investment Bank B : CPI v RPI = 0.2%
• Capacity available : Small
Instrument Approx market size
Indexed RPI gilts £270 bn
Indexed RPI bonds £30 bn
RPI Inflation swaps £100 bn
CPI linked Virtually nil
Insurer solutions
• Will insure on CPI but no discount to RPI
– Expected CPI under-run = cost of additional mismatch
risk capital
• Some insurers able to move from RPI to CPI in future
– In anticipation of CPI market opening up in future
– Part refund of premium
– To whom – scheme or company
– On a buy-in or buy-out?
• Differential pricing?
• Source CPI assets?

• Affordability chart reflects approximate asset/liability mix of
the Scheme (c70% equities and 80% non-pensioners)
• Chart assumes scheme is fully funded initially – for an
underfunded scheme the volatility in the deficit will be much
larger
Our survey says...

Survey Results
1. What proportion of inflation-linked liabilities are matched
with inflation hedging assets such as index-linked gilts,
inflation swaps or buy-in insurance policies:

3. For those that could automatically move to CPI, what
proportion will move (or have actually moved) to CPI
(rather than retain RPI):

should move to CPI?

6. Other:
“Growth asset reduction (and increased matching assets)”
“Changes to investment strategy”
“Reduce scheme benefits – cease accrual”
“Investment triggers”
“Dynamic de-risking using funding level triggers”
“LDI”
“Other asset strategies, e.g. contingent/asset backed
funding”
Survey Results
27© 2010 The Actuarial Profession www.actuaries.org.uk
7. What impact has the CPI move had on schemes
considering de-risking?
“None”
“Funding level increase”
- put buy-in / buy-out back on the agenda
- speeded up growth asset de-risking
“Halted buy-in until market in CPI develops”
“Lack of CPI-linked instruments has made de-risking more difficult”
“Very little yet, many are still awaiting final legal advice on whether CPI
applies”
“Some are waiting for dust to settle before proceeding”
