• Share of GDP: 21,6 per cent

Background of the Fund
BiV/October 2002
The Petroleum Fund:
• The Norwegian Government Petroleum Fund was
established by law in 1990
• The inflow to the Fund is the the central government
budget surplus each year
• The first transfer occurred in May 1996
• The fund is invested in financial assets outside
Norway

Transfers from the Government
Petroleum Revenue
The main purposes of the Petroleum
Fund:
State net cash flow from Petroleum
• A buffer for the government budget to shelter the domestic
economy from volatility in petroleum revenue
250.0
Transfers to the Petroleum Fund
Billion 2002 NOK
200.0
• An instrument for meeting the long-term challenges of a
combination of an expected decline in petroleum resource
revenue and an increase in government pension
expenditures

Why is the Fund invested abroad?
Norway’s national wealth
Percentage distribution
• Budget concern
• The Petroleum Fund should not be a second budget
70
• The Fund does not affect international rates of return - better
returns abroad
60
50
• Monetary policy concern
40
• The petroleum activity yields substantial currency incomes
• Accumulation of foreign reserves in the Fund counteracts
appreciation of the currency

• The Fund as a buffer

• Drawing on a domestic fund could destabilize the economy when

The investment strategy could be divided into:
• Long-term (passive) investment strategy
– Strategic Asset Allocation (SAA)
– reflected in the benchmark
• Short-term (active) investment strategy
– deviation from the benchmark
– increase returns
– reduce costs
BiV/October 2002
Petroleum Fund - Division of responsibilities
• Owner: Ministry of
Finance
• Manager: Norges Bank
– Active investment strategy
– Achieve higher return than
benchmark given
investment mandate and
restrictions
– Risk control
– Reports to MOF
– Give advice to MOF on
Strategic Asset Allocation
– Passive investment strategy
– Strategic asset allocation and
investment universe
– Benchmarks
– Risk limits
– Evaluates manager (uses
consultant)
– Reports to the Parliament
BiV/October 2002
Strategic asset allocation depends on:
Strategic Asset Allocation in benchmark
• Purpose of the Fund
• “In terms of the Petroleum Fund, it is natural to apply a long
investment horizon and to recognize the importance of preserving the
Fund's international purchasing power". (Revised National Budget
1997)

It follows from this model that
the degree of risk aversion
determines the allocation between
risk free rate and market portfolio
(which has a fixed allocation
between bonds and stocks)

Determinig the equity portion
• What is the return on equity investment (the equity
premium puzzle)
• How should we assess the risk associated with
equity investment
• Is the optimal equity portion independent of the
investment horizon?
E(Ri ) = RF + βi ⋅ [E(Rm ) − RF ]
where:
RF - riskfree rate
E(Rm ) - expected return on market portfolio

How should we calculate average return?
Consumption - CAPM
(an example using US data for the period 1926-2000)
E ( Rm ) − R f = γσ (∆c)σ ( Rm ) ρ (∆c, Rm ),
γ - degree of risk aversion
ρ - correlation coefficient (between consumption
growth and asset return
R f - riskfree rate

• “We have a sample of 24 markets for which we have data
in 1931. Out of these, only seven experienced no
interruption (the US, Canada, the UK, Australia, New

temporary suspension of trading, less than a year. The ten
remaining markets suffered a long-term closure.”

• Among large international pension funds there is a
tendency towards using index management for a large
share of the equity portfolio
• Index management is a “standard product”
• Competitive gains seem to be achieved with an increase in
the volume under management (economies of scale)
• Management costs are very low

• by changing the country allocation
• by changing the equity portion
• within the equity portfolio: by increasing
investments in sectors or companies that are
expected to perform better than others
• within the bond portfolio: by changing interestrate risk or credit risk.

Example: Large US pension funds
Risk-adjusted return:
• Fama and French (1993) three-factor model:
– broad stock index
– excess return on a portfolio of small stocks over a
portfolio of large stocks
– excess return on a portfolio of high book-to-market
stocks over a portfolio of low book-to-markets stocks
• Carhart (1997) augmented this model to include:
– a portfolio of stocks with high return over the past
months
BiV/October 2002
BiV/October 2002
11
Considerable debate about the
interpretation of this results
• Entirely spurious and the result of data-snooping
• Inability of the the broad stock index to proxy for
the market portfolio return
• Genuine evidence against CAPM, but not against
a broader model in which there are multiple risk
factors
• Mistakes that disappear once market participants
become aware of them
• Enduring psychological biases that lead investors
to make irrational forecasts
Ethical investments
BiV/October 2002
BiV/October 2002
What are ethical guidelines?
Three options for the Petroleum Fund
•
“The reason we have the phenomenon of social investing is that people are
concerned about such issues as human rights abuses, environmental
degradation and exploitation of workers - and they have taken the fight against
these social ills into the business arena.” (The Journal of Investing, Winter
1997)
• Option 1: Screening
•
“Social investors may be individuals, businesses, universities, hospitals,
pension funds, religious institutions and other non-profit organisations.”
(Social Investment Forum, 1997 Report)
• Option 2: Invest in ethical equity fund
•
A broad set of criteria are currently used to define ethical guidelines: In the
US, the most important criteria are: tobacco (84%), gambling (72%), firearms
(69%), alcohol (68%), birth control (50%), environment (37%), workers’
rights (25%), human rights (23%), animal rights (7%).
• Option 3: Influence enterprises through use of
voting rights
• positive screening ("best-in-class" approach)
• negative screening (black-listing of enterprises/industries)

Ulike paradigmer når det gjelder SRI:
Resultatene for miljøporteføljen så langt:
• Lavere avkastning i
miljøporteføljen enn i
Petroleumsfondets
aksjeportefølje
Det er SRI-effekter i
aksjemarkedene:
SRI-selskaper gir
høyere avkastning
og lavere risiko
enn andre selskaper
