PRESIDENT'S LETTER

DEAR SHAREHOLDER,

Whenever  a new year  begins -- let alone a new  decade or  century  -- it makes
sense to pause a moment to assess where we've been and where we're going.

In  retrospect,  U.S.  stocks  and bonds in 1999  were  subject  to  sudden  and
substantial swings in investor  senti-ment because of economic  uncertainty.When
the year began,  investors were concerned that growth in the United States might
slow in response to  economic  weakness  overseas.At  mid-year,  investors  were
concerned that the economy was too strong,  potentially rekindling  inflationary
pressures.Yet,  by year end, it became clearer that while the U.S.  economy grew
robustly in 1999, inflation remained at low levels.  Indeed,  investors appeared
more comfortable  with the economy after the Federal Reserve Board  demonstrated
its  inflation-fighting  resolve by raising  interest  rates three times between
June and November.

As is  normal  in a  rising-interest-rate  environment,  bond  prices  generally
declined in 1999, led lower by U.S.  Treasury bonds. In the stock market,  while
most major indices advanced,  strong performance was mostly limited to a handful
of large-capitalization  growth companies,  principally in the technology arena.
Smaller and value-oriented stocks provided particularly  lackluster returns and,
overall,  foreign stocks  outperformed U.S. stocks in 1999. Looking forward,  we
expect the U.S. economy to remain on a moderate-growth, low-inflation course. As
recent  revisions of 1999's economic  statistics  demonstrated,  the economy has
defied many  analysts'  forecasts by growing at a strong  rate,  which should be
positive for the bond market. Similarly, positive economic forces could help the
stock market's performance broaden to include value-oriented and smaller stocks.

We see particularly  compelling  opportunities  outside of the U.S. market. Many
foreign  stocks also ended 1999 more  attractively  valued than  large-cap  U.S.
stocks,  and  economic  trends in overseas  markets  could lead to higher  stock
prices.  In Europe,  corporate  restructuring  has just begun,  giving companies
there the same potential for  cost-cutting and  productivity  improvements  that
U.S.  companies  enjoyed 10 years ago. In Japan and Asia,  economic  recovery is
expected to gain strength, which could allow stocks to rally from relatively low
levels.

Another  1999  trend  that  should  remain  in  force in 2000 is the  growth  of
businesses  related to the Internet.  The rise of  e-commerce  has been good for
consumers and the economy because of greater price competition, which has helped
keep inflation under control.The  Internet has also been good for investors,  as
even  companies  with no earnings  have seen their stock prices  soar.  Clearly,
while the Internet is here to stay, not all "dot-com"companies will survive, and
many of these  high-flying  Internet  stocks will eventually -- and perhaps very
suddenly  -- return to more  reasonable  levels.The  long-term  winners are most
likely to be  companies  that  support the  Internet's  growth  with  content or
infrastructure.

What else is in store for investors in 2000?  While we do not have an infallible
crystal  ball, we believe that in almost any  investment  environment,consistent
success stems from an unwavering focus on fundamental investment principles such
as maintaining a long-term  perspective,  using diversification to manage risks,
and  availing  oneself of the  services of a  knowledgeable  financial  advisor.
Indeed,these  principles  serve as the foundation for every investment we offer,
helping to make OppenheimerFunds The Right Way to Invest in 2000 and beyond.

Sincerely,

AN INTERVIEW WITH YOUR FUND'S MANAGER


ARTHUR ZIMMER
JOSEPH WELSH
Portfolio Managers
HOW HAS  OPPENHEIMER  SENIOR FLOATING RATE FUND PERFORMED SINCE ITS INCEPTION ON
SEPTEMBER 7, 1999?

As of January  31,  2000,  the Fund has  performed  well in spite of a difficult
period for the loan market. In particular, we are pleased that the Fund achieved
its objectives of providing investors with an attractive level of current income
while maintaining low levels of share price volatility.

WHAT MADE THIS A DIFFICULT PERIOD FOR THE LOAN MARKET?

A key area of concern was interest  rates.  Despite  multiple  rate hikes by the
Federal  Reserve Board in the second half of 1999,  U.S.  economic growth showed
few  signs of  slowing  to a pace the Fed  might  consider  sustainable.Although
actual  inflation  numbers  remained low, robust  consumer  spending and a tight
labor market  increased the upward  pressure on prices and wages because  rising
rates increase the costs of borrowing.The  possibilities of increasing inflation
and future rate hikes appeared  likely to hurt corporate  borrowers,  especially
those on the weakest financial  footing.As a result,  most investors in the loan
market  sought  to  purchase  only  those  loans  issued by  financially  stable
companies with high credit ratings.

Other  market   difficulties   were  related  to  Y2K  issues.   Driven  by  the
uncertainties  surrounding the millennial date change, an unusually large number
of companies sought to satisfy their capital needs well in advance of January 1,
2000. As a result  corporate loan  issuances rose sharply in September,  October
and  November  1999 and then fell to  negligible  volumes in December  and early
January.  As volume  rose,  prices  generally  declined,  only to climb again as
volume fell.

HOW DID YOU MANAGE THE FUND IN LIGHT OF THESE CONDITIONS?

When we  launched  the Fund on  September  7,  1999,  we took  advantage  of the
favorable  market  conditions  to  invest  in  senior  secured  loans  issued by
companies  with   relatively   high  credit  quality  at  prices  we  considered
attractive.  By the end of November  1999,  when the supply of new issues  began
winding down in  anticipation  of year-end,  we had acquired more than 40 senior
secured  loans  issued by 19 different  entities.We  held  securities  issued by
companies  in  a  diverse  group  of  industries,  such  as  telecommunications,
transportation, energy, chemicals, lodging and manufacturing. Since November, we
have continued to search out relatively high credit quality opportunities in the
market, despite the low supply of new issues.

WHAT ARE YOUR OBJECTIVES FOR THE FUND?

With interest rates at relatively low levels,  investors have few  opportunities
to earn the current income they need without taking undesirable  risks.  Because
bond prices typically move in the opposite direction of changing interest rates,
bond  investors  may find the  current  value of  their  investment  falling  if
interest rates rise. At the same time,  many investors may be wary of locking in
today's low bond yields for the long term.

We established  Oppenheimer Senior Floating Rate Fund for investors seeking high
current income with relative  principal  stability in today's volatile  interest
rate  environment.The  Fund invests primarily in senior secured  adjustable-rate
loans.These  loans have the  potential  to offer  higher  yields than short- and
intermediate-term  securities and investment-grade corporate bonds of comparable
maturities.  (1)They also offer an adjustable  or "floating"  income stream that
helps reduce the volatility of principal  when interest rates rise.  Because the
income from the loans the Fund invests in fluctuates  when  short-term  interest
rates change,  the values of the loans tend to be more stable.  (2) In addition,
senior secured loans tend to provide greater protection against "credit risk" --
the risk that an issuer may be unable to meet its  obligations.  Senior  secured
loans are typically backed by collateral and, in case of default,  have built-in
provisions that require the borrower to make payments on its senior  obligations
before it pays holders of its bonds and stocks.(3)


1. Most of the Fund's  investments in senior loans are below  investment  grade,
which entails greater credit risks, and tend to be illiquid investments.

2. Interest rates on senior floating rate loans reset periodically,  so that the
Fund's share prices will fluctuate in value.

3. There can be no assurance that the  collateral  will be adequate to cover the
borrower's  obligations,  or that the Fund  will be able to sell the  collateral
promptly.

AN INTERVIEW WITH YOUR FUND'S MANAGERS (CONTINUED)


The Fund offers investors  another timely advantage as well.The values of senior
secured floating rate loans  historically have shown low correlation to changing
stock and bond prices. In other words, when stocks or bonds rise or fall, senior
loan values have tended not to move in the same direction.As a result,  the Fund
provides investors with an opportunity to effectively  diversify their holdings,
thereby reducing the overall principal risk level of their portfolio.(4)

WHAT IS YOUR OUTLOOK FOR THE FUND?

We believe that  companies that put their capital needs on hold in late 1999 are
likely to reenter the market in early 2000.  As the volume of new loan  issuance
increases, we expect new opportunities to emerge for the Fund to invest in loans
with good yields at attractive  prices.  If the U.S. economy continues to expand
at or near its present pace, we believe  upward  pressure on interest  rates may
rise,   increasing  the  volatility  of  stock  and  bond  prices.  In  such  an
environment,  the Fund is strongly  positioned to help investors earn attractive
levels of income while reducing the risk of the  volatility of their  principal,
which is why  Oppenheimer  Senior Floating Rate Fund is an important part of The
Right Way to Invest.


The  Fund's  performance  may  from  time  to  time be  subject  to  substantial
short-term  changes,  particularly  during  periods of market or  interest  rate
volatility. For updates on the Fund's performance, please contact your financial
advisor,    call    us    at    1.800.525.7048    or    visit    our    website,
www.oppenheimerfunds.com.


4.  The  Fund is a  non-diversified  fund,  which  means  that it can  invest  a
relatively  greater  percentage  of its  assets  in fewer  issuers  compared  to
diversified funds.

1.  SIGNIFICANT ACCOUNTING POLICIES
Oppenheimer  Senior  Floating  Rate  Fund  (the  Fund) is  registered  under the
Investment  Company Act of 1940, as amended,  as a  non-diversified,  closed-end
management  investment company. The Fund seeks as high a level of current income
and preservation of capital as is consistent with investing  primarily in senior
floating rate loans and other debt obligations. The Fund's investment advisor is
OppenheimerFunds, Inc. (the Manager).

The Fund  offers  Class A,  Class B and Class C shares.  Class A shares  are not

initial  sales  charge  but may be subject to an Early  Withdrawal  Charge.  All
classes  of  shares  have  identical  rights  to  earnings,  assets  and  voting
privileges, except that each class has its own expenses directly attributable to
that class and exclusive  voting rights with respect to matters  affecting  that
class.  Classes A, B and C shares  have  separate  distribution  and/or  service
plans.  Class B shares  will  automatically  convert to Class A shares 72 months
after  the end of the month in which  you  purchase  them.  The  following  is a
summary of significant accounting policies consistently followed by the Fund.

SECURITIES VALUATION.  Securities for which quotations are readily available are
valued at the last sale price,  or if in the absence of a sale, at the last sale
price on the prior trading day if it is within the spread of the closing bid and
asked  prices,  and if not,  at the  closing  bid price.  Securities  (including
restricted securities) for which quotations are not readily available are valued
primarily  using  dealer-supplied   valuations,   a  portfolio  pricing  service
authorized  by the Board of  Trustees,  or at their  fair  value.  Fair value is
determined  in good  faith  under  consistently  applied  procedures  under  the
supervision  of the Board of  Trustees.  Short-term  "money  market  type"  debt
securities  with  remaining  maturities of sixty days or less are valued at cost
(or last determined  market value) and adjusted for amortization or accretion to
maturity of any premium or discount.

SENIOR LOANS. Under normal market conditions,  the Fund will invest at least 80%
of its total assets in  collateralized  floating  rate senior loans made to U.S.
and foreign  borrowers  that are  corporations,  partnerships  or other business
entities.  The Fund will do so either as an original lender or as a purchaser of
an assignment of a loan or a participation interest in a loan. Most senior loans
are illiquid.  As of January 31, 2000, securities with an aggregate market value
of $100,791,621,  representing 90.57% of the Fund's net assets were comprised of
senior loans.

SECURITY  CREDIT  RISK.  Senior  loans are subject to credit  risk.  Credit risk
relates to the ability of the borrower  under a senior loan to make interest and
principal  payments on the loan as they become due.  The Fund's  investments  in
senior loans are subject to risk of default.

NON-DIVERSIFICATION  RISK. The Fund is  "non-diversified"  and can invest in the
securities of a single issuer.  To the extent the Fund invests a relatively high
percentage  of its  assets in the  obligations  of a single  issuer or a limited
number of  issuers,  the Fund is  subject  to  additional  risk of loss if those
obligations  lose market  value or the  borrower or issuer of those  obligations
defaults.

REPURCHASE  AGREEMENTS.  The Fund requires the custodian to take possession,  to
have  legally  segregated  in the Federal  Reserve  Book Entry System or to have
segregated  within the custodian's  vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of  purchase.  If the seller
of the agreement  defaults and the value of the collateral  declines,  or if the
seller  enters  an  insolvency  proceeding,  realization  of  the  value  of the
collateral by the Fund may be delayed or limited.

FEDERAL  TAXES.  The Fund intends to continue to comply with  provisions  of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  all of its  taxable  income,  including  any  net  realized  gain on
investments  not  offset by loss  carryovers,  to  shareholders.  Therefore,  no
federal income or excise tax provision is required.

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  distributions to
shareholders,  which are determined in accordance  with income tax  regulations,
are recorded on the ex-dividend date.

1.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CLASSIFICATION  OF DISTRIBUTIONS TO SHAREHOLDERS.  Net investment  income (loss)
and net realized gain (loss) may differ for financial statement and tax purposes
primarily  because of paydown  gains and losses and the  recognition  of certain
foreign currency gains (losses) as ordinary income (loss) for tax purposes.  The
character of  distributions  made during the year from net investment  income or
net  realized  gains may differ from its ultimate  characterization  for federal
income tax purposes.  Also, due to timing of dividend distributions,  the fiscal
year in which amounts are  distributed  may differ from the fiscal year in which
the income or realized gain was recorded by the Fund.

EXPENSE OFFSET ARRANGEMENTS.  Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Fund.

OTHER.  Investment  transactions are accounted for as of trade date and dividend
income is recorded on the ex-dividend date. Discount on securities  purchased is
amortized over the life of the respective securities, in accordance with federal
income tax  requirements.  Realized gains and losses on investments  and options
written and  unrealized  appreciation  and  depreciation  are  determined  on an
identified  cost  basis,  which is the same  basis used for  federal  income tax
purposes. Dividends-in-kind are recognized as income on the ex-dividend date, at
the current market value of the underlying security. Interest on payment-in-kind
debt instruments is accrued as income at the coupon rate and a market adjustment
is made periodically.

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the reported amounts of income and expenses during the reporting period.  Actual
results could differ from those estimates.

2.  SHARES OF BENEFICIAL INTEREST
The Fund has  authorized 40 million of no par value  shares.  Class A shares are
not available for direct purchase. The Fund will sell Class B and Class C shares
continuously at the respective offering price for each class of shares. The Fund
will make  periodic  repurchase  offers.  Transactions  in shares of  beneficial
interest were as follows:

3.  UNREALIZED GAINS AND LOSSES ON SECURITIES
As of January 31, 2000, net unrealized depreciation on securities of $37,820 was
composed of gross appreciation of $239,076, and gross depreciation of $276,896.

4.  FEES AND OTHER TRANSACTIONS WITH AFFILIATES
MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the
investment advisory agreement with the Fund which provides for a fee of 0.75% of
the first $200 million of average net assets of the Fund, 0.72% of the next $200
million,  0.69% of the next $200 million,  0.66% of the next $200  million,  and
0.60% of  average  net  assets  in  excess  of $800  million.  The  Manager  has
voluntarily  agreed to reduce  its  management  fee by 0.20%  annually  and from
commencement  of  operations  through  the period  ended  January 31,  2000,  to
voluntarily waive the fee entirely. Either waiver may be amended at anytime. The
Fund's  management  fee for the period  ended  January  31,  2000,  gross of any
waivers was 0.75% of average  annual net assets,  annualized for periods of less
than one full year.

TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the Manager,
is the  transfer  and  shareholder  servicing  agent  for the Fund and for other
registered  investment  companies.  OFS's total costs of providing such services
are allocated ratably to these companies.

DISTRIBUTION  AND SERVICE PLAN FEES. Under its General  Distributor's  Agreement
with the Manager,  the Distributor acts as the Fund's  principal  underwriter in
the continuous public offering of the different classes of shares of the Fund.

The Fund has  adopted a Service  Plan for Class A shares  and  Distribution  and
Service Plans for Class B and Class C. Because the Fund is a closed-end fund and
is not able to rely on the  provisions of Rule 12b-1 of the  Investment  Company
Act (the Act),  the Fund has  requested  and obtained  from the  Securities  and
Exchange  Commission (the SEC) exemptive  relief from certain  provisions of the
Act. The operation of those plans is contingent upon the continued  availability
of that  exemptive  relief  from the SEC.  Under  those  plans the Fund pays the
Distributor  for all or a portion of its costs  incurred in connection  with the
distribution and/or servicing of the shares of the particular class.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES  (continued)
CLASS A SERVICE PLAN FEES.  Under the Class A service plan, the Distributor
currently  uses the fees it receives  from the Fund to pay brokers,  dealers and
other financial institutions. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares  purchased.  While the plan  permits the Board of  Trustees to  authorize
payments to the Distributor to reimburse itself for services under the plan, the
Board has not yet done so. The  Distributor  makes  payments to plan  recipients
quarterly at an annual rate not to exceed 0.25% of the average annual net assets
consisting  of  Class A  shares  of the  Fund.  Any  unreimbursed  expenses  the
Distributor  incurs with  respect to Class A shares in any fiscal year cannot be
recovered in subsequent years.

CLASS B AND CLASS C SERVICE AND DISTRIBUTION PLAN FEES. Under each plan, service
fees and distribution fees are computed on the average of the net asset value of
shares in the  respective  class,  determined  as of the  close of each  regular
business  day during the period.  The Class B and Class C plans  provide for the
Distributor  to  be  compensated  at a  flat  rate,  whether  the  Distributor's
distribution  expenses  are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.

The  Distributor  retains the  asset-based  sales charge on Class B shares.  The
Distributor  retains the  asset-based  sales charge on Class C shares during the
first year the shares are outstanding.  The asset-based sales charges on Class B
and Class C shares  allow  investors  to buy shares  without a  front-end  sales
charge while  allowing the  Distributor  to  compensate  dealers that sell those
shares.

The  Distributor's  actual expenses in selling Class B and Class C shares may be
more than the payments it receives from the early withdrawal  charges  collected
on  repurchased  shares and from the Fund under the plans.  If either Class B or
Class C plan is terminated by the Fund, the Board of Trustees may allow the Fund
to continue  payments of the  asset-based  sales charge to the  Distributor  for
distributing shares before the plan was terminated.

5.  ILLIQUID OR RESTRICTED SECURITIES
As of January 31,  2000,  investments  in  securities  included  issues that are
illiquid.  A security may be considered illiquid if it lacks a readily available
market or if its  valuation has not changed for a certain  period of time.  Most
Senior  Loans  and  many of the  Fund's  other  investments  are  illiquid.  The
aggregate value of illiquid  securities subject to this limitation as of January
31, 2000 was $100,791,621, which represents 90.57% of the Fund's net assets.

6.  BANK BORROWINGS
The Fund may borrow from a bank for temporary or emergency  purposes  including,
without limitation,  funding of shareholder  repurchases provided asset coverage
for  borrowings  exceeds  300%.  The Fund has entered  into an  agreement  which

credit with a bank, which permits  borrowings up to $400 million,  collectively.
Interest is charged to each fund,  based on its  borrowings,  at a rate equal to
the  Federal  Funds Rate plus 0.45%.  Borrowings  are payable 30 days after such
loan is  executed.  The Fund  also pays a  commitment  fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of 0.08%
per annum.

The Fund had no borrowings  outstanding  during the six months ended January 31,
2000.

7.       SUBSEQUENT EVENT
Effective March 9, 2000, the Fund's existing borrowing  agreement was terminated
and the Fund entered into a new agreement  which enables it to participate  with
other  Oppenheimer  funds in an  unsecured  line of  credit  with a bank,  which
permits borrowings up to $100 million, collectively. Interest is charged to each
fund,  based on borrowings at a rate equal to the Federal Funds Rate plus 0.65%.
Borrowings are payable 30 days after such loan is executed. The Fund also pays a
commitment fee equal to its pro rata share of the average  unutilized  amount of
the credit facility at a rate of 0.09% per annum.
