SIMPLIFIED AND FULL PROSPECTUS

A simplified  prospectus with  information on  Rorento N.V.  and  its
associated costs and risks  is available. This simplified  prospectus
and the full prospectus are available at the company's office and via
www.robeco.com

R E P O R T  OF  T H E  S U P E R V I S O R Y  B O A R D

We herewith present the Rorento N.V. accounts for the financial  year
2005 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
Institutional Asset Management B.V. Rorento  N.V. is the employer  of
the management board members. Discussion of the management of Rorento
N.V. can 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 the supervisory  board therefore  primarily
devotes its attention to the investment policy, the realized  results
and the development of the assets invested, on the basis of  frequent
and detailed reports. Attention is  also paid to matters relating  to
risk  management,  such   as  operational  and   market  risks,   and
compliance, such  as  investment  restrictions  and  compliance  with
requirements of the  regulator. In connection  with what has  already
been mentioned regarding the structure of the Robeco Group,  matters,
such  as  the  risks  associated  with  the  investment  policy,  the
application of  instruments  to  manage these  risks  and  compliance
issues, 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
Management Board  of  Robeco  Groep N.V.  in  consultation  with  its
supervisory  board.  This   means  that  matters   such  as   product
development,  acquisitions,  risk   management  and  compliance   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.
In the report of the supervisory  board in the 2004 annual report,  a
reference was made  to the  report of the  Committee for  Modernising
Collective Investment  Schemes which  was  published on  22  December
2004. The recommendations of this report have not yet been fully laid
down  in  law.  We  are  also  waiting  for  further  recommendations
regarding fund governance. As was the  case in the 2004 report,  this
annual report has already taken  several of these recommendations  in
account.
Based on the  implementation of the  revised Investment  Institutions
Supervision Act as of 1 September  2005, an application will be  made
to the Netherlands Authority for the Financial Markets for a  license
as mentioned  in that  act.  An application  for  a new  license  for
Rorento N.V.  was  submitted to  the  Netherlands Authority  for  the
Financial Markets  in late  February 2006.  The prospectus  has  been
adjusted as a result of  the revision of the Investment  Institutions
Supervision Act. The  amended prospectus has  been submitted to  both
the Netherlands Authority for the  Financial Markets and the  Central
Bank of the Netherlands Antilles.
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.

At the  General Meeting  of Shareholders  on 27  April 2005,  Mr.  J.
Kremers relinquished  his position  as supervisory  director,  having
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.
At the same meeting  Mr. Ph. Lambert was  appointed as a  supervisory
director of the company  with immediate effect,  to fill the  vacancy
arising from the departure of Mr.  C.E.M. Beckers as of 1 July  2004.
At the General  Meeting of  Shareholders Mr.  P.C. van  den Hoek  was
reappointed as  chairman  of  the supervisory  board  with  immediate
effect. The vacancy as a result  of Mr. Kremers' resignation has  not
yet been filled.
At the same  meeting Mr.  K.J.V. Tavenier  also resigned  of his  own
accord as a  member of the  management board of  Rorento N.V. On  the
same day, Mr. F.L.I. van  de Walle was appointed  as a member of  the
management board  to  fill the vacancy  arising from Mr.  Tavernier's
departure.  The  board  is  extremely  grateful  for  Mr.  Tavenier's
contribution to the development of Rorento N.V.
According to schedule, Mr. D.P.M. Verbeek will resign at the  General
Meeting of Shareholders  to be held  on 10 May  2006. Mr. Verbeek  is
available for reelection. It is proposed that he be reappointed as  a
supervisory director of the company with immediate effect.

REPORT OF THE MANAGEMENT BOARD

GENERAL INTRODUCTION

Global economy remains convincing
In 2005 global economic growth  remained high. The United States  and
Asia were the main growth engines but in the course of the year Japan
joined them and even  the European economy started  to show signs  of
improvement towards the end of the year.
The US economy  continued to do  well in spite  of the higher  energy
prices  and  the  impact  of  hurricane  Katrina.  Consumer  spending
remained strong thanks to  better labor-market circumstances and  the
strength of the housing market.  Inflation increased to levels  above
4% but underlying inflation, excluding  energy prices, was much  more
moderate.  The   inflation  outlook   remained  stable,   which   was
undoubtedly due to the determination  with which the US central  bank
kept raising its official rates. In the course of the year short-term
rates were raised from 2.25% to 4.25% in 25 basis-point steps. In the
euro zone corporate capital expenditure especially contributed to the
moderate growth. The  export sector  benefited from  the recovery  in
global trade.  Domestic spending  lagged once  again because  of  the
unstable  recovery  of  the  labor  market.  Due  to  the  continuing
unemployment, the higher  oil price  has not (yet)  led to  excessive
wage demands. The depreciation of the euro, tax increases and  higher
energy prices pushed inflation in the euro zone to levels above 2.5%.
Here too underlying inflation was  much lower. However, the  European
Central Bank  still  raised its  official  rate  by a  quarter  of  a
percentage point to 2.25%. It was the first interest-rate move in 2.5
years.
The economic picture  for Japan has  improved significantly over  the
past year. Economic growth is no longer just supported by the  export
sector as  domestic spending  is  also increasingly  contributing  to
growth. Wage  growth and  the  improving labor  market are  the  main
growth engines. The Japanese central bank has also made it clear that
it will soon start  normalizing its extremely accommodative  monetary
policy.

Bond markets were mixed
The series of rate hikes by the US central bank has had an effect  on
US bond  returns.  Bonds  with  a short  life  to  maturity    lagged
particularly.  The  spread  between  official  short-term  rates  and
capital-market rates narrowed to close to zero. Because the inflation
outlook remained  moderate, in  spite of  higher commodities  prices,
capital-market  rates   rose  only   slightly.  In   the  euro   zone
capital-market  rates  actually  dropped,  which  led  to  more  than
reasonable returns  on euro-denominated  bonds. Capital-market  rates
only started increasing again towards the  end of the year, when  the
Euroland economy started  to gain  in strength. Here  too the  spread
between short-term and long-term rates decreased, especially when the
European Central Bank raised  rates by 0.25% towards  the end of  the
year. In  Japan  capital-market  rates  rose  slightly  in  2005  and
speculations about  possible  monetary  tightening  also  put  upward
pressure on bond yields.
The non-government bond market was mixed in 2005. The European credit
market clearly outperformed its US counterpart, where returns were on
balance lower than the returns on government bonds. In the course  of
the year there were some company-specific events which had a negative
impact for bondholders, but the effect  on the market as a whole  was
only limited. Investors did have  a preference for short-term  loans,
as  a  result  of  which  the  difference  in  risk  premium  between
short-term and long-term loans increased.
Outlook
Central banks  will continue  to reverse  the accommodative  monetary
measures of  the past  years. Their  main objective  is to  keep  the
inflation outlook  stable. We  think that  they will  be  successful.
Capital-market rates will rise a  little further, but we expect  this
rise to be moderate. Structural factors which curb inflation, such as
globalization and technological progress, are still present. For  the
time being, wage pressure will be  tempered by cheap labor from  Asia
and sufficient labor potential in Europe. Oil-price movements  remain
a risk factor.
The macroeconomic outlook for businesses is not unfavorable. However,
our expectations for the return  on credits are low. Businesses  will
more often opt  for extra  capital expenditure  or raising  dividend,
partly due to pressure from  venture capitalists, and will give  less
priority to  reducing  debt. These  risks  are not  yet  sufficiently
reflected in the current risk premiums.

INVESTMENT POLICY

Duration, country and yield-curve policy
During most of  2005, Rorento's portfolio  was positioned for  rising
interest rates in  the euro  zone, the US  and Japan.  Capital-market
rates in  the  US  fluctuated  between  3.8%  and  4.60%  during  the
reporting year.  The American central bank tightened monetary policy.
The discount rate was raised from  2.25% to 4.25% in 25  basis-points
steps. The American central bank used  this policy to respond to  the
increased inflationary pressure and solid economic growth, which  was
primarily the result of continuing consumer spending. During the same
period, the rise in capital-market rates  in the US was limited.  The
market expected that the devastation caused by the hurricanes in  the
Southern United States and the sharp rise in oil prices would have  a
negative impact on the US economy. Interest-rate hikes combined  with
slightly increasing capital-market  rates caused the  yield curve  in
the US  to flatten  significantly.  During almost  the whole  of  the
period under  review, Rorento  was  positioned for  this  yield-curve
flattening and therefore benefited from it.

European capital-market rates fluctuated between 3.0% and 3.8% during
the reporting year.  The eurozone  economy grew  modestly during  the
first half  of  2005, with  continuing  high unemployment  in  Italy,
France and Germany. As a result, ten-year yields fell to a record low
of 3.0%. Exports increased during the second half of the year, helped
by a  weak  euro,  thereby improving  economic  sentiment.  When  the
European Central Bank (ECB) started signaling that it wanted to raise
money-market  rates  in  order  to  combat  inflation  and  normalize
money-market rates, long-term bonds were sold and interest rates rose
to 3.5%. Because money-market rates rose and capital-market rates for
longer maturities remained  under pressure due  to continuing  demand
from European pension funds and insurance companies, the yield  curve
flattened significantly  during the  last  quarter of  the  reporting
period. The fund successfully anticipated this in the last quarter.
Regional allocation was  another strategy used  by Rorento. The  fund
was overweight in the euro  zone at the expense  of the US. The  idea
behind this was that the American central bank was expected to  raise
money-market rates, while the ECB was expected to keep interest rates
stable during most of 2005. We took the view that the spread  between
US interest rates and Euroland  interest rates would increase,  which
in fact is what actually happened.
Also in Japan, interest rates tended towards higher levels during the
second half  of the  year; they  rose  to a  level around  1.5%.  The
economic recovery  brought  the end  of  the deflationary  period  in
sight, as a result of which the Bank of Japan will also pursue a less
accommodative policy  in  the  future.  The  portfolio  is  currently
positioned for a  further increase in  Japanese interest rates.  This
position also contributed positively to the fund's performance.

Risk Management and compliance
On  the  basis   of  reports   the  management   board  spoke   about
risk-management and compliance issues,  and also discussed them  with
the supervisory board.

Financial instruments
The  fund  uses  financial  instruments.  The  associated  risks  are
specified in the financial statements.

Credits
Halfway through the reporting year, the allocation to corporate bonds
in the portfolio was lowered to  a more neutral position relative  to
the benchmark. The  more defensive  positioning was  prompted by  the
relatively  high  valuation  of   the  asset  category  compared   to
government bonds. The favorable macroeconomic outlook for  businesses
indeed justified the relatively low premiums for credit risk, but the
increased activity of so-called
venture capitalists was cause for concern. Rorento was also  involved
in these  activities, with  a number  of companies  in its  portfolio
becoming the target of hostile  takeovers or the subject of  takeover
speculation. Thanks to the use  of derivatives in the portfolio,  the
fund was  able to  benefit in  a number  of cases  from the  loss  of
creditworthiness, which often  happens in  these so-called  leveraged
buyouts (LBOs).   Because financial companies  are less sensitive  to
such  restructurings,  the  overweight  in  financials  compared   to
corporates was further increased in the course of the year.
As of September,  the sensitivity  to the credit  market was  further
reduced. The  increased  uncertainty  in  the  credit  market  and  a
flattening of the underlying yield curve of government bonds resulted
in higher risk premiums for long-term bonds.

Currencies
The most  important  development  in  the  currency  market  was  the
impressive comeback of  the US dollar  compared to other  currencies,
driven by  the continuing  positive  economic outlook,  the  widening
short-rate differentials, and  higher global demand.  During most  of
the year, the portfolio was overweight in the euro compared to the US
dollar, which  contributed  negatively. Other  transactions  such  as
JPY/USD, GBP/USD and CHF/USD made a limited contribution on balance.

Performance
During the period under review, the fund manager's active  investment
policy led  to an  outperformance of  1.4% (before  deduction of  the
management fee) relative to  the benchmark. Of  this 1.4%, 0.57%  was
attributable to the  duration policy, 0.56%  to the regional  policy,
0.43% to the  yield-curve policy, 0.22%  to the money-market  policy,
- -0.25% to the credit policy and -0.13% to the currency policy.

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
Netherlands Authority  for the  Financial  Markets) under  the  Dutch
Investment  Institutions   Supervision  Act   ['Wtb',  Wet   toezicht
beleggingsinstellingen].  The  revised  Wtb  became  effective  on  1
September 2005.

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 on a daily  basis at prices approximating  net asset value.  A
fixed spread between the bid and  offer price applies to cover  costs
related to issuance  and repurchase  of own shares.  The issue  price
will not be more than  1.0% higher than the  net asset value and  the
repurchase price will not be more than 0.5% lower than the net  asset
value. Until 31 May 2005 Robeco Investment Consulting B.V. functioned
as the  intermediary  between  Rorento N.V.  and  investors  for  the
issuance and repurchase of own  shares. Rorento N.V. agreed with  the
other Robeco  Group  funds that  from  1 June  2005  onwards,  Robeco
Investment Consulting B.V. would assume the integrated management and
risk of spread income and expenses of these Robeco funds, 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  Robeco  Investment Consulting  B.V.  Robeco  Investment
Consulting B.V. will distribute any  positive results, to the  funds,
in proportion  to each  fund's positive  contribution to  the  spread
result. A buffer is maintained to cover any future losses. Due to the
abolition of capital tax as of 1 January 2006, the upper limit of the
spread was lowered from 1% to 0.5%.

Non-certificated participation in the Netherlands
Parties with  which  shares  may be  held  in  non-certificated  form
include Robeco Direct N.V. in the Robeco Group Accounts System or the
affiliated branches  of  Rabobank  in the  Rabo  Securities  Account.
Participants pay costs on the sum deposited for each purchase, and in
the event  of  a  sale  a percentage  of  the  sum  withdrawn.  These
participation costs are currently a maximum of 0.4% via Robeco Direct
and a  maximum  of  0.5%  via  Rabobank,  depending  on  the  channel
selected. These  sums  will  accrue to  Robeco  Direct  and  Rabobank
respectively.

Outsourcing core tasks
The administration has been outsourced to Robeco Institutional Asset
Management 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  thousands
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, credit-default  swaps and  forward purchases  of
mortgage-backed securities (TBAs) this value  is based on the  market
price and  other  market quotations  at  closing date.  Deposits  and
CDs/CP 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,
fund-administration  services,  as  well  as  management  activities.
Transactions are executed at market rates.

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  transactions   in  currencies,  including   forward
transactions, 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  another  currency  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 instruments, including  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.

Derivatives
The market  value of  derivatives is  reported in  the Balance  sheet
under Financial  investments and  Accounts payable.  Liabilities  and
receivables and the value of the derivatives' underlying  instruments
are not  included  in the  Balance  sheet. If  applicable,  they  are
explained under  the heading  Commitments not  shown in  the  balance
sheet.

A breakdown of this  portfolio and an overview  of the spread of  net
assets can be  found at the  end of this  report. A substantial  part
(35%; previous year 79%)  of the total purchases  and sales shown  in
the table relates to repo transactions. Repo transactions current  at
balance-sheet date represent  a value  of EUR  176 million  (previous
year EUR 611 million).
At balance-sheet  date, bonds  to the  amount of  EUR 502  million  (
previous year EUR 506 million at the end of last year) had been lent.
To cover  the risk  of non-restitution,  adequate collateral  with  a
value of EUR 533 million  was demanded and obtained; this  collateral
is not included in the Balance sheet.

                  _______ _______
Total                0.78    0.65

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
0.78% during the reporting period. The management costs relate to all
of the  fund's  current  costs,  which  include  the  fees  paid  for
registering shareholders and all costs resulting from the  management
of the fund, with the exception of costs relating to investments  and
taxes. 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 14. 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, amounting to EUR 277 thousand, and  bank
charges.

15 Management costs and service fee
Management costs relate  exclusively to the  management fee of  0.70%
per year charged  by Robeco Institutional  Asset management B.V.  The
service  fee  amounts  to  0.08%  per  year  and  covers  formal  and
operational costs. For assets exceeding EUR 1 billion the service fee
is 0.06%;  for assets  exceeding EUR  5 billion  the service  fee  is
0.04%. The fees are calculated on a daily basis, based on the average
assets entrusted.  Wherever in  this report  mention is  made of  the
average assets entrusted this  is also calculated  on a daily  basis,
unless stated otherwise.

16 Other costs
This includes custody costs and bank charges.

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

18 Transaction costs
Brokerage costs and exchange fees relating to investment transactions
are discounted in the cost price or the sales value of the investment
transactions. 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  ensuing from  changes
in value. The quantifiable transaction  costs are included under  the
heading Movements  in value  in  the Profits  and loss  account.  The
transaction volume  of the  quantifiable  transaction costs  is  6.1%
(previous year 0%) of the  total transaction volume. Bonds cover  63%
(previous  year  53%)  of  the  transaction  volume  excluding   repo
transactions, whose transaction costs are not quantifiable.

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

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  205% for  2005 (versus 193%  for the  previous
year). Rorento's turnover in 2005 was almost the same as in 2004.  In
2005, a further reduction of positions in corporate bonds also played
a role in  this. Furthermore, the  active overweight and  underweight
positions taken  in the  course  of the  year affected  the  turnover
figures.

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 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. An
external agency periodically assesses whether the agreements  between
the fund and  Robeco Securities Lending  are still in  line with  the
market. In  2005  the proceeds  for  the  fund amounted  to  EUR  450
thousand (last year EUR 395 thousand). For Robeco Securities  Lending
this was EUR 300 thousand (last year EUR 263 thousand).

23 Personnel costs
Rorento N.V. does not employ personnel, except for boardmembers.
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).  A  limited group  of  employees,  including
several fund  managers,  are  given the  opportunity  to  participate
directly in  Robeco's future  through virtual  shares (E-notes).  The
individual allocation of E-notes is linked to individual  performance
and the contribution to the  realization of the strategic targets  of
the Robeco Group as a whole  and the individual's own business  unit.
The E-notes  represent a  value which  is directly  linked to  Robeco
Groep N.V.'s value.
