REPORT OF THE SUPERVISORY BOARD

We herewith present the Rorento N.V. accounts for the financial year
2004 together with the report of the management board.
The way in which the supervisory board carries out its supervisory
duties is significantly determined by the structure of the Robeco
Group. The management of Rorento N.V. is carried out by Robeco
Nederland B.V., which employs the personnel who work for Rorento
N.V., including its management board. Robeco Nederland B.V. is a
wholly-owned subsidiary of Robeco Groep N.V. Discussion of the
management of Rorento N.V. can therefore take place in the
supervisory board of either the company or that of Robeco Groep N.V.
As a result of the personal links between the members of the two
boards, in practice this presents no difficulties.
The purpose of an investment institution such as Rorento N.V., as
laid down in its Articles of Association, is limited to the investing
of its assets in securities in such a way that risks are diversified
with the object of allowing its shareholders to participate in the
profits. At its meetings therefore, the supervisory board devotes
extensive attention to the investment policy, the realized results
and the development of the assets invested, on the basis of frequent
and detailed reports. In connection with the above regarding the
structure of the Robeco Group, matters which are also relevant to
Rorento N.V., such as the risks associated with the investment policy
and the application of instruments to manage these risks, may also be
discussed at the meetings of the supervisory board of Robeco Groep
N.V.
The general policy of the Robeco Group is determined by the executive
board of Robeco Groep N.V. in consultation with its supervisory
board. This means that matters such as product development,
acquisitions and risk management are discussed at the meetings of the
supervisory board of Robeco Groep N.V. An audit and remuneration
committee has been appointed by this board, and intensive discussions
were held with the internal audit department and the external auditor
concerning matters affecting the whole Robeco Group. Two members of
this committee are also supervisory directors of Rorento N.V. Besides
the subjects mentioned, no special issues were discussed at the
meetings of the supervisory board during the reporting year.
The Committee for Modernising Collective Investment Schemes (known as
the 'Winter Committee') published its report on 22 December 2004. The
consequences of the recommendations in this report for the Robeco
Group will be evaluated in the course of 2005. In anticipation of
their recording in regulations, several of these recommendations were
already taken into account in this annual report.
We have taken note of the contents of the auditor's report presented
by Ernst & Young Accountants and recommend approval of the annual
financial statements. The management board proposes not to distribute
the profit but to allocate this income to Other Reserves, as usual.
Messrs. P.A.W. Roef and A. Ruys stepped down as members of the
supervisory board at the General Meeting of Shareholders held on 5
May 2004. At the same meeting Messrs. G. Izeboud and C.E.M. Beckers
were appointed as supervisory directors of the company with immediate
effect. Mr. Beckers resigned of his own accord on 1 July 2004 because
of a possible conflict of interests relating to a new position he had
accepted in the financial world.
It will be proposed at the General Meeting of Shareholders that Mr.
Ph. Lambert be appointed as a supervisory director of the company
with immediate effect to fill the vacancy arising form Mr. Becker's
resignation, on condition that the appointment is approved by the
Central Bank of the Netherlands Antilles. Mr. Lambert works at
Unilever as head of Corporate Pensions and in that capacity is
responsible for the pensions and investments of Unilever's  global
pension fund.
Furthermore, at the aforementioned meeting of 5 May 2004 Messrs. J.J.
van Duijn (chairman), B. Vliegenthart and G.B. Smith resigned as
members of the management board. Mrs. E.J. Siermann was appointed as
a member of the management board of Rorento N.V. as of the same date.
Mr. J. Kremers will retire as a supervisory director at the General
Meeting of Shareholders on 27 April 2005, as he has reached the
statutory retirement age. Mr. Kremers has been a member of the
supervisory board since 1997. The board is extremely grateful for his
important contribution to the exercise of its advisory and
supervisory duties throughout this period.
According to schedule, Mr. P. van den Hoek will resign at the General
Meeting of Shareholders to be held on 27 April 2005. Mr. van den Hoek
is available for reelection. It is proposed that he be reappointed as
a supervisory director of the company with immediate effect.
At the General Meeting Mr. K.J.V. Tavenier will also, of his own
accord, resign as a member of the management board of Rorento N.V. To
fill the vacancy arising from his departure, it will be proposed that
Mr. F.L.I. van de Walle be appointed as a member of the board with
immediate effect, subject to the approval of the central Bank van de
Nederlandse Antillen. The board is extremely grateful for Mr.
Tavenier's contribution to the development of Rorento N.V.

The supervisory board



REPORT OF THE MANAGEMENT BOARD

GENERAL INTRODUCTION

Recovery of the global economy continues in 2004
The global economy again showed considerable growth in 2004 as the
recovery that began in the previous year continued. Companies saw
their earnings rise as a result of ongoing cost-cutting and
increasing turnover. Consumers continued to spend, encouraged partly
by rising house prices and slightly improved employment prospects.
However worries about the sustainability of economic growth also
remained. Rising commodity prices formed a threat and extra demand
from emerging economies, such as China, pushed prices higher. These
price movements were exacerbated by speculators. Political
uncertainty in various oil-producing countries was also a
contributory factor. Another source of concern was the depreciation
of the US dollar and the resulting deterioration in the US trade
balance and the US government's budget deficit.
Despite the higher commodity prices, inflation remained moderate.
This can partly be attributed to structural factors such as the
intensified international competition and the improved productivity
in many sectors. Another contributory factor was that the capacity
surplus accumulated at the end of the 1990s had not been completely
eliminated. It was therefore not easy for companies to pass on price
increases to consumers. Finally there was a lack of wage-cost
inflation. For the time being, the labor reserve in most countries is
still large enough to curb wage demands.
Differences between the regions still existed  in 2004. The US
economy performed relatively well. Consumer spending was high. US
household savings have fallen on balance, which was  partly caused by
 the rising house prices. The euro zone's performance was once again
disappointing. The main reason was that a pick-up in domestic demand
failed to materialize,  which in turn was due to consumers' concerns
about the consequences of structural reforms and labor-market
conditions. The emerging economies in Asia are becoming increasingly
important. Partly because of its geographical location, Japan is also
benefiting from this and it seems that the period of deflation there
has now come to an end. However, this has not led the Japanese
monetary authorities to increase official short-term interest rates.
The European central bank also left its official rates unchanged,
whereas the US central bank started reversing the interest-rate cuts
of previous years.

The bond markets performed well
In 2004, US capital-market rates remained unchanged. This is
surprising considering that halfway through the year the Federal
Reserve Bank began to normalize monetary conditions by raising
official short-term rates in five steps from 1% to 2.25%. The absence
of inflationary pressure explains the limited reaction of the bond
market as does the fact that Asian central banks bought large
quantities of US government bonds.  These transactions stemmed from a
desire to protect their local currencies from appreciating against
the US dollar. In the eurozone, capital-market rates declined further
in response to the region's lagging economic development. In Japan,
capital-market rates did rise but only slightly, when it became clear
that the economic outlook was more positive and that the period of
deflation seemed to be over.
Non-government bonds, including high yield, saw good returns in
2004.  As in 2003, the climate was favorable for credits last year.
Companies' focus on a healthy balance sheet and free cash flow
ensured that their creditworthiness remained stable and in some cases
improved. This, combined with investors' strong demand for extra
returns, caused the average risk premium to fall further, to the
lowest level in the last five years.
Outlook
The US central bank is expected to further normalize its official
interest rates in 2005, but the speed at which this will occur
depends on the inflation and employment levels in the United States.
This will also determine the direction of capital-market rates. We
expect that the low US yields will begin to rise at some point in
2005. Whether the European Central Bank will also tighten its
monetary policy in the short term remains to be seen. Due to the
strong euro in combination with slower economic growth expectations
that this will occur are not high. We therefore think that European
government bonds will outperform in the period to come.
We expect the macroeconomic environment to remain favorable for
credits this year. Partly due to considerable restructuring and
cost-cutting, companies are now in better shape than they were a
while ago. This favorable picture is reflected in current
corporate-bond valuations.  We do not anticipate a further decline in
risk premiums. In addition companies will gradually shift their focus
to more growth-related initiatives.  The first signs of this are
already visible in the increased merger and acquisition activities.
Given the still strong demand for corporate bonds and related
products in combination with the relatively short supply of new
paper, we do not expect that the average risk premium will rise
significantly.

Duration and country-allocation policy
Capital-market rates in the US, the eurozone and Japan moved in a
rather narrow trading range during the first few months of this year.
The return of healthy economic growth, especially in the United
States, has so far been accompanied by low inflation and little
change in the level of unemployment, keeping the interest-rate
markets in balance. Rorento anticipated higher US capital market
rates , based on the view that the labor-market situation would
improve. In February, unexpectedly poor US macroeconomic figures,
mostly relating to employment and consumer confidence, caused
interest rates to decline sharply and the underweight position was
subsequently closed in early March. The 10-year US Treasury yield
fell from around 4.2% at the beginning of February to lower than 3.7%
in mid-March. The other bond markets followed. Very quickly however,
it transpired that the markets had moved in the wrong direction as an
unexpectedly strong increase in the number of jobs in the US caused a
sharp correction in the major capital markets. Inflation also rose,
partly due to the high price of oil. As a result of this, the
likelihood that the Fed would raise interest rates increased. Since
the Japanese economy, after many years of disappointments, finally
began to show clear signs of recovery, bond yields moved rapidly
higher in all markets. Rorento quickly moved to underweight positions
in April, this time not only in the US but also in the eurozone and
Japan. Bond yields reached a temporary high in mid-June. Towards the
end of June the situation reversed. Economic-growth and capital
expenditure figures were disappointing. Fed officials indicated that
the pace of rate hikes would probably slacken somewhat, which led to
a renewed rally in US and European bond markets and caused
capital-market rates to fall. Although US economic data still
indicated reasonably healthy growth, in the summer months it appeared
that the market had already discounted the good news. Disappointing
news like a slightly lower-than-expected GDP growth figure and
disappointing US job growth therefore led to strong price movements
and falling bond yields. Europe was unable to escape this trend,
which is not surprising considering this region's markedly weaker
economic situation. The surging oil price was not interpreted by the
market as a sign of strong global economic growth but rather as an
obstacle to future growth and this resulted in a further decline in
capital-market rates. The 10-year US Treasury yield fell from a peak
of 4.9% in June to below 4% in September. Rorento also held an
underweight duration position in the various regions during part of
this period of falling interest rates but closed these positions in
August.
A rather exceptional situation occurred in the fourth quarter as US
capital-market rates resumed their upward trend, while European
capital-market rates continued their downtrend. The disappearance of
the correlation between these two markets seldom occurs because
usually the same macroeconomic data effect the corporate sector and
economic growth in both regions. However, the dollar's free fall of
more than 10% in one quarter against the euro, led to increased fears
of inflation in the US and the expectation that the Fed would again
increase money-market rates more quickly and steeply. In Europe, on
the other hand, the strong appreciation of the euro increased
expectations that economic growth would be curbed further and that
inflation would not be a significant issue for the ECB for the time
being. In addition, US macroeconomic figures still compared very
favorably with those of eurozone countries. Consequently, the
difference between US and European 10-year yields increased from
almost nil to approximately 70 basis points. Rorento responded to
this development by combining an overweight in Europe with an
underweight in the US for a large part of the fourth quarter, a
decision which proved to be excellent.
Besides having an active policy with regard to the interest-rate
sensitivity of the portfolio as a whole, spread trades are also used
to take advantage of differences in the relative attractiveness of
countries and regions . In addition to the aforementioned spread
trade between Europe and the US in the fourth quarter, the fund held
overweight positions in the Australian and New Zealand bond markets
during a large part of the first three quarters. Corresponding
underweight positions were taken in US bonds. Rorento was also
overweight in South African bonds in the first quarter of 2004.
Almost throughout the entire period under review, the portfolio was
positioned to benefit from a flatter yield curve in the US and in May
a position was taken to benefit from a steeper yield curve in the
eurozone.

Policy regarding non-government bonds
The continuing economic recovery led to a favorable climate for
corporate bonds which also benefitted from strongly improved balance
sheets, the focus on healthy financial ratios and the use of low
interest-rate levels for cheap refinancing and reducing interest
burdens. Throughout 2004 the market was still supported by strong
demand for extra returns and because of this, for corporate bonds.
Rorento was overweight in corporates throughout the reporting period,
despite this market's excellent rally in 2003. This was,
nevertheless, a good decision as corporates once again clearly
outperformed government bonds during the whole of 2004. The fund was
mainly overweight in the lower rating categories of A and BBB.
However, in the summer this overweight in corporate bonds was
considerably reduced. This move was mainly triggered by the fact that
the valuation of this investment category had risen strongly. Rorento
however maintains a small overweight which is concentrated in the
financials and industrials sectors. The reduced overweight in
corporates also led to a smaller overweight in the lower rating
categories.
High-yield and emerging-country debt also benefited from the improved
outlook for the global economy. Rorento was more or less neutrally
positioned in these markets throughout the reporting period.

Currency policy
After a trend of euro weakness began in February, Rorento took an
overweight position in the dollar, which was brought back to neutral
in May. In June and July Rorento was overweight in the euro and the
Swiss franc against the US dollar. Also in October the fund briefly
held overweight positions in the euro, the Swiss franc and the
Japanese yen against the dollar.

NOTES

General
Rorento (hereafter also referred to as 'the fund') is an investment
institution registered in the Netherlands Antilles and as such is not
subject to Dutch corporate-income tax or capital tax. It is only
liable to pay a minor sum in Netherlands Antilles profits tax. The
financial statements are in euros and are drawn up in accordance with
regulations prevailing in the Netherlands. The fund holds a license
in accordance with article 11, section a, of the National Ordinance
on the Supervision of Investment Institutions and Administrators
('Ltba', Landsverordening Toezicht op Beleggingsinstellingen en
Administrateurs). The fund also holds a license from the AFM (the
Dutch Authority for the Financial Markets) under the Dutch Investment
Institutions Supervision Act ('Wtb', Wet toezicht
beleggingsinstellingen).

System change
As a result of changes to the Guidelines for Annual Reporting, with
effect from the 2004 financial year changes in the value of
investments, both realized and unrealized, are reported in the Profit
and loss account. Furthermore, the market value of derivatives, which
was formerly reported under sundry debtors or sundry creditors is now
reported under financial investments. In the Profit and loss account
under Other costs a number of specific costs are reported including
costs that were previously charged directly to net assets. The change
has no effect on the assets as at 31 December 2003 and 31 December
2004. The effect on the result over 2003 amounts to EUR -92 million,
and over 2004 EUR -19 million. Comparative figures in this report
have been adjusted accordingly where necessary.

Models
The annual financial statements have been drawn up in conformity with
the models provided by Dutch legislature. In certain areas
descriptions have been used which better express the nature of the
items and relate better to the characteristics of an investment
company.

Open-end fund
Rorento N.V. is an open-end investment company, meaning that, barring
exceptional circumstances, Rorento N.V. issues and repurchases its
shares via the intermediary on a daily basis at prices approximating
net asset value. Robeco Investment Consulting B.V. functions as the
intermediary between Rorento N.V. and investors for the issuance and
repurchase of shares, as a result of which Rorento N.V. issues and
repurchases its shares at net asset value. The abovementioned margin
between the net asset value and the bid and offer prices, and the
associated costs, are for the account and risk of the intermediary.
The intermediary will distribute any positive results, calculated
cumulatively, to the funds on a quarterly basis. Distribution will be
in proportion to each fund's positive contribution to the
intermediary's result. A buffer is maintained to cover any future
losses.

Outsourcing core tasks
The administration has been outsourced to Robeco Institutional Asset
Management B.V. (until 1 October 2001 to Avirento B.V.), a 100%
subsidiary of Robeco Groep N.V. These costs are covered by the
service fee. Agreements have been made with the aforementioned party
relating to the provision of information and performance standards.









accounting principles

General
Unless stated otherwise, items shown in the annual financial
statements are included at nominal value and expressed in millions of
euros.

Financial investments
Financial investments are included at fair value. The fair value of
bonds and other fixed-income securities is based on the market price
and other market quotations at closing date. For derivatives such as
forward exchange contracts, this value is based on currency rates and
reference interest rates at closing date and for futures,
interest-rate swaps and forward purchases of mortgage-backed
securities this value is based on the market price and other market
quotations at closing date. Deposits and certificates of CDs/CPs are
valued on the basis of exchange rates and reference interest rates at
closing date. For call money, the real value is the nominal value.
Transaction costs incurred in the purchase and sale of investments
are included in the purchase or sale price as appropriate.

Affiliated parties
Rorento N.V. is affiliated to the entities belonging to Robeco Groep
N.V. The affiliation with Robeco Groep N.V. is the result of the
possibility of having decisive control or a substantial influence on
the fund's business policy. Robeco Groep N.V. belongs to the Rabobank
Group. The management structure of Robeco Groep N.V., in which
significant authority is allocated to its independent supervisory
board, is such that Rabobank does not have a meaningful say in or
influence on the fund's business policy. Robeco Groep N.V. pursues an
independent investment policy on behalf of its affiliated investment
companies, taking into account the interests of the investors
involved. Besides services of other market parties, Rorento N.V. also
uses the services of one or more of these affiliated entities
including transactions relating to securities, treasury, derivatives,
custody, securities lending, and sale and purchase of its own shares,
as well as management activities. Transactions are executed at market
rates.

Hard commissions and soft-dollar arrangements
There were no hard commissions or soft-dollar arrangements during the
reporting period.

determination of the result

General
Investment results are determined by interest income, rises or
declines in stock prices, rises or declines in foreign exchange rates
and results of (forward) transactions in currencies and derivative
instruments. The results are accounted for in the Profit and loss
account.

Investment income
Interest income on investments in bonds, other fixed-income
securities, deposits, other financial investments, cash and income
from loan transactions. Accrued interest at balance-sheet date is
taken into account.

Movements in value
Realized and unrealized capital gains and losses on securities and
currencies.

Foreign currencies
Transactions in currencies other than the euro are converted into
euros at the exchange rates valid at the time. Assets and liabilities
expressed in other currencies are converted into euros at the
exchange rate prevailing at balance-sheet date. Any exchange
differences arising are accounted for in the Profit and loss account.





FINANCIAL INSTRUMENTS

Risk
Transactions in financial instruments may lead to the fund being
subject to the risks described below or to the fund transferring
these risks to another party.
Price risks
Currency risk is the risk that the value of a financial instrument
will fluctuate as a result of changes in exchange rates.
Interest-rate risk is the risk that the value of a financial
instrument will fluctuate as a result of changes in market rates. The
value of investments in fixed-income securities depends directly on
market rates. Duration is used as the measure for the portfolio's
sensitivity to interest-rate movements. The portfolio's sensitivity
to fluctuations in market rates can be influenced by changing the
portfolio's duration. Further information on the duration policy can
be found in the report of the management board. Market risk is the
risk that the value of a financial instrument will fluctuate as a
result of changes in market prices, caused by factors that
exclusively apply to the individual instrument or its issuer or
caused by factors that affect all instruments traded in the market.
The fund minimizes risks by diversifying over countries, currencies
and issuers. Investments are made primarily in bonds issued or
guaranteed by OECD member countries and by companies based in these
countries. The fund pursues an active currency policy. Rorento
invests a limited part of its assets in paper qualified as high yield
by rating agencies.
Credit risk
Credit risk is the risk that the counterparty of a financial
instrument will no longer meet its obligations, as a result of which
the fund will suffer a financial loss. The fund minimizes this risk
by trading exclusively with reputable counterparties with a rating of
at least P1 from Moody's or A from Standard & Poor's. Wherever it is
customary in the market, the fund will demand and obtain collateral.
Liquidity risk
Liquidity risk is the risk that the fund is not able to obtain the
financial means required to meet the obligations arising from
financial instruments. The fund minimizes this risk by mainly
investing in financial instruments that are tradable on a daily
basis.

Insight into actual risks
The report of the management board, the balance sheet, the notes to
the balance sheet and the spread of net assets, which includes the
geographic distribution of the investments and the net currency
position, give an insight into the actual risks at balance-sheet
date.

Risk management
Managing risk is a part of the investment process as a whole and with
the help of advanced systems, the risks outlined above are limited,
measured and monitored on the basis of fixed risk measures.

Policy regarding the use of derivative instruments
Investing implies that positions are taken. As it is possible to use
various (derivative) instruments to construct an identical position,
the selection of derivatives is subordinate to the positioning of a
portfolio. In our published information, attention is given primarily
to the overall position, and secondarily to the nature and volume of
the financial instruments employed.
Derivative instruments
The market value of derivatives is reported in the Balance sheet
under Financial investments. Liabilities and receivables and the
values of derivatives' underlying instruments are not included in the
Balance sheet. They are, however, explained under the heading
Commitments not shown in the balance sheet.

The total expense ratio expresses the costs charged to the fund
during the reporting period as a percentage of the average assets
entrusted during the reporting period. The total expense ratio as
shown does not include transaction costs. The total expense ratio was
0.65% during the reporting period. With the exception of costs
relating to investments and taxes, the management costs relate to all
the fund's costs and all costs resulting from the management of the
fund. The service fee covers the administration, the costs of the
external auditor, other external advisers, regulators, costs relating
to reports required by law, such as the annual and semiannual
reports, and the costs relating to the meetings of shareholders.
The total expense ratio takes into account the costs of intra-group
investments, as presented in the table on page 19; as the management
fee is restituted to Rorento, these costs are not material and are
therefore not included in the above table.
Other costs mainly relate to the custody fee charged by third parties
for the custody of the fund's securities portfolio.

15 Management costs and service fee
It is the Robeco group's policy to present the costs of its funds as
transparently as possible, furthermore Robeco aims at a cost level
more or less equal to the average of the European market, combined
with high-level service and advice.
With effect from 1 October 2004, the management fee on the average
assets entrusted has been raised from 0.60% to 0.70% a year, to bring
it more in line with the market. Furthermore, a service fee was
introduced to cover formal and operational costs such as the
production of annual reports and the fund's administration. It is
market practice to directly charge these costs to the fund. The
Robeco Group has chosen to charge a fixed annual fee to cover these
expenses to make the actual costs transparent to its clients. The
service fee for Rorento N.V. will be 0.12% per year. For assets
exceeding EUR 1 billion the service fee is 0.10%; for assets
exceeding EUR 5 billion the service fee is 0.08%. The fees are
calculated on a daily basis, based on the average assets entrusted.
Before 1 October 2004 the average assets entrusted was calculated on
an annual basis, based on 13 observations.

16 Securities lending
Robeco Securities Lending B.V. is the intermediary for all Rorento
N.V.'s securities-lending transactions. As compensation for its
services Robeco Securities Lending B.V. receives a fee of 40% of the
gross income resulting from these securities-lending transactions.

17 Other costs
This includes custody costs and bank charges.

18 Performance fee
Rorento N.V. does not charge a performance fee.



19 Transaction costs
Brokerage costs and exchange fees relating to investment transactions
are discounted in the sots price or the sales value of the
investment. Brokerage costs for the purchase and sale of bonds are
included in the share price and cannot be quantified separately.
These costs and fees are charged to the result.

20 Turnover ratio
This is the turnover ratio of the investments against the average
assets entrusted and this is a measure of the incurred transaction
costs resulting from the portfolio policy pursued and the ensuing
investment transactions. In the calculation method that is used the
amount of turnover is determined by the sum of purchases and sales of
investments less the sum of issuance and repurchase of own shares. If
the outcome is negative, the turnover ratio is 0. The turnover ratio
is determined by expressing the amount of turnover as a percentage of
the average assets entrusted. The turnover ratio is corrected for
repo transactions, which are not part of the portfolio policy but
generate extra return on the portfolio. The turnover ratio excluding
repo transactions was 193% for 2004 (versus 168% for the previous
year). Rorento's turnover in 2004 was slightly higher than in 2003.
This was partly due to the reduction of the considerable overweight
in corporate bonds in the second half of 2004. Furthermore, the
number of active (overweight and underweight) positions, taken
throughout a year, effects the fund's total turnover. In this respect
2004 was a fairly normal year, which did not differ much from 2003.


21 Transactions with affiliated parties
Part of the transaction volume over the reporting period relates to
transactions with affiliated parties. The table below shows the
various types of transactions where this was the case.

22 Personnel costs
Rorento N.V. does not employ personnel.
Robeco Nederland B.V.'s remuneration policy for fund managers
consists of both a fixed and a variable income. The secondary
conditions of employment are in line with what is common practice in
the financial-services industry.
The fixed income offers a good and competitive remuneration basis
within the Dutch asset-management market. A fund manager is assigned
to a salary scale with a minimum and maximum income based on the
level of responsibility of his function (HAY method for function
valuation). Growth within this scale is linked to (performance)
results and competencies.
The variable income offers the fund manager remuneration for his
individual, long-term outperformance. Payment is related to the
outperformance relative to a preset target.
The track record over both a 1-year and 3-year period is taken into
account when determining the variable remuneration. The variable
remuneration to which the fund manager is entitled for any single
year is paid out over a 3-year period (60% in the first year, 30% in
the second and 10% in the last year).


23 Supervisory directors' fee
An amount of EUR 34,598 (previous year EUR 37,434) has been allocated
from the proposed profit appropriation for this purpose.

* Modified duration is a measure of the interest-rate sensitivity and
interest-rate risk of a portfolio, and represents the approximate
percentage change in the value of the portfolio as a result of a 1
percent increase or decrease in interest rates. The use of derivative
instruments allows the amount of the portfolio's modified duration to
be managed separately from the direct bond investments. The
application of derivatives therefore allows the fund to adopt an
optimal yield-curve positioning. The use of derivative instruments is
limited to the setting of limits for the total modified duration of
the portfolio.
