FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED DECEMBER 31, 2005, FOLLOWED
BY A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO APPROPRIATE BROAD-BASED
MARKET INDICES.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. For the fiscal year ended December
31, 2005, Oppenheimer Convertible Securities Fund Class A shares (without sales
charge) performed competitively versus its primary and secondary benchmarks, as
shown in the graphs that follow.

      Our favorable performance was attributed to an array of factors. First,
our decision to overweight our exposure to the energy sector, which continued to
fare well thanks to prolonged strength in the price of crude oil and natural
gas, significantly added to returns for the fiscal year. Similarly, our decision
to substantially underweight our exposure to auto-related convertibles--which
generally suffered this period--helped performance. While these tactics proved
to benefit our returns throughout the entire review period, we enjoyed a
significant boost to returns from these decisions particularly in the second
half of the year.

      Both absolute and relative performance was supported by our overweighted
exposure to financial-services related convertibles, while our individual
security selection within this industry sector further added to returns. The
fact that we emphasized outperforming sub-segments of this category, such as
insurance and investment-management companies, and sought to keep low our
exposure to banks and savings and loan institutions, which lagged in a rising
interest-rate environment, definitively added to the Fund's returns.

      Our careful security selection and active management of the portfolio's
emphasis within the health care sector also positively impacted performance.
Although the health care sector as a whole did not deliver uniformly strong
performance, we enjoyed good success in terms of our individual security
selection within this category. Select holdings such as Teva Pharmaceutical
Industries, a generic pharmaceutical company, proved to deliver strong
performance for the Fund particularly in the second half of the year, and
thereby added to overall returns. Similarly, Omnicare, a large pharmacy-services
company, was a significant outperformer in the second half of the year and added
to performance.

      The fact that we effectively worked to refocus and sharpen the portfolio's
overall quality profile over the course of the fiscal year positively
contributed to our generally favorable returns this period. For a select portion
of the portfolio, we had previously targeted underperforming companies that, in
our opinion, represented good relative value with solid performance potential.
This year, we refocused this portion of the portfolio on higher-quality
companies with more consistent track records regarding their stock

performance and earnings momentum, and are pleased to report that this
initiative positively impacted our returns for the year.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until December 31, 2005. In the case of Class A, Class B, and Class M
shares, performance is over a 10-year period. In the case of Class C shares,
performance is measured from inception of the Class on March 11, 1996. In the
case of Class N shares, performance is measured from inception of the Class on
March 1, 2001. The Fund's performance reflects the deduction of the maximum
initial sales charge on Class A and Class M shares, the applicable contingent
deferred sales charge on Class B, Class C and Class N shares, and reinvestments
of all dividends and capital gains distributions.

      The Fund's performance is compared to the performance of the Lehman
Brothers Aggregate Bond Index, Goldman Sachs Convertible Bond 100 Index, and the
S&P 500 Index. The Lehman Brothers Aggregate Bond Index is a broad-based,
unmanaged index of U.S. corporate bond issues, U.S. government securities and
mortgage-backed securities, widely recognized as a measure of the performance of
the domestic debt securities market. The Goldman Sachs Convertible Bond 100
Index is an unmanaged index of convertible securities. The S&P 500 Index is a
broad-based index of equity securities widely regarded as a general measurement
of the performance of the U.S. equity securities market. Index performance
reflects the reinvestment of income but does not consider the effect of
transaction costs, and none of the data in the graphs shows the effect of taxes.
The Fund's performance reflects the effects of the Fund's business and operating
expenses. While index comparisons may be useful to provide a benchmark for the
Fund's performance, it must be noted that the Fund's investments are not limited
to the investments in the indices.

NOTES
- --------------------------------------------------------------------------------

Total returns and the ending account values in the graphs include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares.

INVESTORS SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER
CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS
THIS AND OTHER INFORMATION ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR
FINANCIAL ADVISOR, CALLING US AT 1.800.525.7048 OR VISITING OUR WEBSITE AT
WWW.OPPENHEIMERFUNDS.COM. READ THE PROSPECTUS CAREFULLY BEFORE INVESTING.

The Fund's investment strategy and focus can change over time. The mention of
specific fund holdings does not constitute a recommendation by OppenheimerFunds,
Inc.

CLASS A shares of the Fund were first publicly offered on 5/1/95. The Fund's
maximum sales charge for Class A shares was lower prior to 3/11/96, so actual
performance may have been higher. Class A returns include the current maximum
initial sales charge of 5.75%.

CLASS B shares of the Fund were first publicly offered on 5/1/95. Class B
returns include the applicable contingent deferred sales charge of 5% (1-year)
and 2% (5-year). Because Class B shares convert to Class A shares 72 months
after purchase, the 10-year return for Class B uses Class A performance for the
period after conversion. Class B shares are subject to an annual 0.75%
asset-based sales charge.

CLASS C shares of the Fund were first publicly offered on 3/11/96. Class C
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class C shares are subject to an annual 0.75% asset-based sales charge.


                  17 | OPPENHEIMER CONVERTIBLE SECURITIES FUND


NOTES
- --------------------------------------------------------------------------------

CLASS M shares of the Fund were first publicly offered on 6/3/86. Class M
returns include the current maximum initial sales charge of 3.25%. Prior to
March 11, 1996, Class M shares were designated as Class A shares. While Class M
shares are subject to an annual 0.50% asset-based sales charge, the Board has
set that charge at zero effective February 11, 2004.

CLASS N shares of the Fund were first publicly offered on 3/1/01. Class N shares
are offered only through retirement plans. Unless otherwise noted, Class N
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class N shares are subject to an annual 0.25% asset-based sales charge.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and service fees;
and other Fund expenses. These examples are intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended December 31, 2005.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you paid for the
period. You may use this information to compare the ongoing costs of investing
in the Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold with the 5% hypothetical examples that appear in
the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in


                  19 | OPPENHEIMER CONVERTIBLE SECURITIES FUND



FUND EXPENSES
- --------------------------------------------------------------------------------

the Statement of Additional Information). Therefore, the "hypothetical" lines of
the table are useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

Class N Hypothetical         1,000.00        1,017.80         7.50

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended December 31, 2005 are as follows:

CLASS            EXPENSE RATIOS
- -------------------------------
Class A               0.99%
- -------------------------------
Class B               1.83
- -------------------------------
Class C               1.77
- -------------------------------
Class M               0.94
- -------------------------------
Class N               1.47

The expense ratios reflect voluntary waivers or reimbursements of expenses by
the Fund's Transfer Agent that can be terminated at any time, without advance
notice. The "Financial Highlights" tables in the Fund's financial statements,
included in this report, also show the gross expense ratios, without such
waivers or reimbursements.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Convertible Securities Fund (the Fund), a portfolio of the Bond Fund
Series, is registered under the Investment Company Act of 1940, as amended, as
an open-end management investment company. The Fund's investment objective is to
seek a high level of total return on its assets through a combination of current
income and capital appreciation. The Fund's investment advisor is
OppenheimerFunds, Inc. (the Manager).

      The Fund offers Class A, Class B, Class C, Class M and Class N shares.
Class A shares are sold at their offering price, which is normally net asset
value plus a front-end sales charge. Class B, Class C and Class N shares are
sold without a front-end sales charge but may be subject to a contingent
deferred sales charge (CDSC). Class M shares are sold with a reduced front-end
sales charge. Class N shares are sold only through retirement plans. Retirement
plans that offer Class N shares may impose charges on those accounts. All
classes of shares have identical rights and voting privileges with respect to
the Fund in general and exclusive voting rights on matters that affect that
class alone. Earnings, net assets and net asset value per share may differ due
to each class having its own expenses, such as transfer and shareholder
servicing agent fees and shareholder communications, directly attributable to
that class. Class A, B, C, M and N have separate distribution and/or service
plans. Class B shares will automatically convert to Class A shares six years
after the date of purchase.

      The following is a summary of significant accounting policies consistently
followed by the Fund.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Fund calculates the net asset value of its shares as
of the close of The New York Stock Exchange (the Exchange), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for business. Securities may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Trustees. Securities listed or traded on National
Stock Exchanges or other domestic exchanges are valued based on the last sale
price of the security traded on that exchange prior to the time when the Fund's
assets are valued. Securities traded on NASDAQ are valued based on the closing
price provided by NASDAQ prior to the time when the Fund's assets are valued. In
the absence of a sale, the security is valued 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 traded on foreign
exchanges are valued based on the last sale price on the principal exchange on
which the security is traded, in the country that is identified by the portfolio
pricing service, prior to the time when the Fund's assets are valued. In the
absence of a sale, the security is valued at the official closing price on the
principal exchange. Corporate, government and municipal debt instruments having
a remaining maturity in excess of sixty days and all mortgage-backed securities
will be valued at the mean between the "bid" and "asked" prices. Futures
contracts traded on a commodities or futures exchange will be valued at the
final settlement price or official closing price on the principal exchange as
reported by such principal exchange at its trading session ending at, or most
recently prior to, the


                  36 | OPPENHEIMER CONVERTIBLE SECURITIES FUND


time when the Fund's assets are valued. Securities (including restricted
securities) for which market quotations are not readily available are valued at
their fair value. Foreign and domestic securities whose values have been
materially affected by what the Manager identifies as a significant event
occurring before the Fund's assets are valued but after the close of their
respective exchanges will be fair valued. Fair value is determined in good faith
using 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 amortized cost (which
approximates market value).

- --------------------------------------------------------------------------------
STRUCTURED NOTES. The Fund invests in structured notes whose market values,
interest rates and/or redemption prices are linked to the performance of
underlying foreign currencies, interest rate spreads, stock market indices,
prices of individual securities, commodities or other financial instruments or
the occurrence of other specific events. The structured notes are often
leveraged, increasing the volatility of each note's market value relative to the
change in the underlying linked financial element or event. Fluctuations in
value of these securities are recorded as unrealized gains and losses in the
accompanying Statement of Operations. The Fund records a realized gain or loss
when a structured note is sold or matures. As of December 31, 2005, the market
value of these securities comprised 4.3% of the Fund's net assets and resulted
in unrealized cumulative gains of $487,536.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

- --------------------------------------------------------------------------------
ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

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

The tax components of capital shown in the table below represent distribution
requirements the Fund must satisfy under the income tax regulations, losses the
Fund may be

2. As of December 31, 2005, the Fund had $2,318,493 of post-October losses
available to offset future realized capital gains, if any. Such losses, if
unutilized, will expire in 2014.

3. During the fiscal year ended December 31, 2005, the Fund utilized $7,504,322
of capital loss carryforward to offset capital gains realized in that fiscal
year.

4. During the fiscal year ended December 31, 2004, the Fund utilized $22,626,011
of capital loss carryforward to offset capital gains realized in that fiscal
year.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for December 31, 2005. Net assets of
the Fund were unaffected by the reclassifications.

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of December 31, 2005 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and

TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for the
Fund's independent trustees. Benefits are based on years of service and fees
paid to each trustee during the years of service. During the year ended December
31, 2005, the Fund's projected benefit obligations were decreased by $23,574 and
payments of $2,545 were made to retired trustees, resulting in an accumulated
liability of $89,945 as of December 31, 2005.

      The Board of Trustees has adopted a deferred compensation plan for
independent trustees that enables trustees to elect to defer receipt of all or a
portion of the annual compensation they are entitled to receive from the Fund.
For purposes of determining the amount owed to the Trustee under the plan,
deferred amounts are treated as though equal dollar amounts had been invested in
shares of the Fund or in other Oppenheimer funds selected by the Trustee. The
Fund purchases shares of the funds selected for deferral by the Trustee in
amounts equal to his or her deemed investment, resulting in a Fund asset equal
to the deferred compensation liability. Such assets are included as a component
of "Other" within the asset section of the Statement of Assets and Liabilities.
Deferral of trustees' fees under the plan will not affect the net assets of the
Fund, and will not materially affect the Fund's assets, liabilities or net
investment income per share. Amounts will be deferred until distributed in
accordance to the Plan.

- --------------------------------------------------------------------------------
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. Income distributions, if any, are declared
and paid quarterly. Capital gain distributions, if any, are declared and paid
annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date

may have passed. Non-cash dividends included in dividend income, if any, are
recorded at the fair market value of the securities received. Interest income,
which includes accretion of discount and amortization of premium, is accrued as
earned.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. Custodian Fees and Expenses in the Statement of Operations may
include interest expense incurred by the Fund on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash overdrafts to the extent they are not
offset by positive cash balances maintained by the Fund. The Reduction to
Custodian Expenses line item, if applicable, represents earnings on cash
balances maintained by the Fund during the period. Such interest expense and
other custodian fees may be paid with these earnings. At December 31, 2005, the
Fund had $413 of such earnings on cash balances available to offset future
custodian fees or interest expenses incurred during the next fiscal year.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. 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 an unlimited number of no par value shares of beneficial

- ----------------------------------------------------------

- --------------------------------------------------------------------------------
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 at an
annual rate of 0.625% of the first $50 million of average annual net assets of
the Fund, 0.50% of the next $250 million and 0.4375% of average annual net
assets over $300 million.

- --------------------------------------------------------------------------------

accounting services agreement with the Fund which provides for an annual fee of
$12,000 for the first $30 million of average daily net assets and $9,000 for
each additional $30 million of average daily net assets. During the year ended

account fee. For the year ended December 31, 2005, the Fund paid $784,346 to OFS
for services to the Fund.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12B-1) FEES. Under its General Distributor's
Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor)
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan for Class A
shares. It reimburses the Distributor for a portion of its costs incurred for
services provided to accounts that hold Class A shares. Reimbursement is made
periodically at an annual rate of up to 0.25% of the average annual net assets
of Class A shares of the Fund. The Distributor currently uses all of those fees
to pay dealers, brokers, banks and other financial institutions periodically for
providing personal services and maintenance of accounts of their customers that
hold Class A shares. Any unreimbursed expenses the Distributor incurs with
respect to Class A shares in any fiscal year cannot be recovered in subsequent
years. Fees incurred by the Fund under the Plan are detailed in the Statement of
Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C, CLASS M AND CLASS N SHARES.
The Fund has adopted Distribution and Service Plans for Class B, Class C, Class
M and Class N shares to compensate the Distributor for its services in
connection with the distribution of those shares and servicing accounts. Under
the plans, the Fund pays the Distributor an annual asset-based sales charge of
0.75% on Class B and Class C shares and 0.25% on Class N shares. While the Class
M plan permits an annual asset-based sales charge payment of 0.50%, the Board
has set that payment at zero effective February 11, 2004. The Distributor also
receives a service fee of 0.25% per year under each plan. If either the Class B,
Class C, Class M or Class N plan is terminated by the Fund or by the
shareholders of a class, the Board of Trustees and its independent trustees must
determine whether the Distributor shall be entitled to payment from the Fund of
all or a portion of the service fee and/or asset-based sales charge in respect
to shares sold prior to the effective date of such termination. The
Distributor's aggregate uncompensated expenses under the plan at December 31,
2005 for Class B, Class C and Class N shares were $2,401,687, $2,308,403 and
$29,903, respectively. Fees incurred by the Fund under the plans are detailed in
the Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and contingent deferred sales charges
(CDSC) do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the table below for the period indicated.

WAIVERS AND REIMBURSEMENTS OF EXPENSES. OFS has voluntarily agreed to limit
transfer and shareholder servicing agent fees for all classes to 0.35% of
average annual net assets per class. During the year ended December 31, 2005,
OFS waived $385 for Class N shares. This undertaking may be amended or withdrawn
at any time.

- --------------------------------------------------------------------------------
5. ILLIQUID SECURITIES

As of December 31, 2005, 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. The
Fund will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.

- --------------------------------------------------------------------------------
6. LITIGATION

A consolidated amended complaint has been filed as putative derivative and class
actions against the Manager, OFS and the Distributor, as well as 51 of the
Oppenheimer funds (as "Nominal Defendants") including the Fund, 30 present and
former Directors or Trustees and 8 present and former officers of the funds.
This complaint, initially filed in the U.S. District Court for the Southern
District of New York on January 10, 2005 and amended on March 4, 2005,
consolidates into a single action and amends six individual previously-filed
putative derivative and class action complaints. Like those prior complaints,
the complaint alleges that the Manager charged excessive fees for distribution
and other costs, improperly used assets of the funds in the form of directed
brokerage commissions and 12b-1 fees to pay brokers to promote sales of the
funds, and failed to properly disclose the use of assets of the funds to make
those payments in violation of the Investment Company Act of 1940 and the
Investment Advisers Act of 1940. Also, like those prior complaints, the
complaint further alleges that by permitting and/or participating in those
actions, the Directors/Trustees and the Officers breached their fiduciary duties
to shareholders of the funds under the Investment Company Act of 1940 and at
common law. The complaint seeks unspecified compensatory and punitive damages,
rescission of the funds' investment advisory agreements, an accounting of all
fees paid, and an award of attorneys' fees and litigation expenses.

6. LITIGATION Continued

      The defendants believe that the allegations contained in the Complaints
are without merit and that they have meritorious defenses against the claims
asserted. The defendants intend to defend these lawsuits vigorously and to
contest any claimed liability. The defendants believe that it is premature to
render any opinion as to the likelihood of an outcome unfavorable to them and
that no estimate can yet be made with any degree of certainty as to the amount
or range of any potential loss.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER BOND FUND SERIES:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Convertible Securities Fund (a portfolio of the Bond Fund Series),
including the statement of investments, as of December 31, 2005, and the related
statement of operations for the year then ended, the statements of changes in
net assets for each of the years in the two-year period then ended, and the
financial highlights for each of the years in the five-year period then ended.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
An audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 2005, by correspondence with
the custodian. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Oppenheimer Convertible Securities Fund as of December 31, 2005, the results of
its operations for the year then ended, the changes in its net assets for each
of the years in the two-year period then ended, and the financial highlights for
each of the years in the five-year period then ended, in conformity with U.S.
generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2006, if applicable, shareholders of record received information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2005. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      Dividends, if any, paid by the Fund during the fiscal year ended December
31, 2005 which are not designated as capital gain distributions should be
multiplied by 11.58% to arrive at the amount eligible for the corporate
dividend-received deduction.

      A portion, if any, of the dividends paid by the Fund during the fiscal
year ended December 31, 2005 which are not designated as capital gain
distributions are eligible for lower individual income tax rates to the extent
that the Fund has received qualified dividend income as stipulated by recent tax
legislation. $2,468,350 of the Fund's fiscal year taxable income may be eligible
for the lower individual income tax rates. In early 2006, shareholders of record
will receive information regarding the percentage of distributions that are
eligible for lower individual income tax rates.

      Recent tax legislation allows a regulated investment company to designate
distributions not designated as capital gain distributions, as either interest
related dividends or short-term capital gain dividends, both of which are exempt
from the U.S. withholding tax applicable to non U.S. taxpayers. For the fiscal
year ended December 31, 2005, $13,982,384 or 66.56% of the ordinary
distributions paid by the Fund qualifies as an interest related dividend. The
Fund did not distribute a short-term capital gain.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of
the complexity of the federal regulations which may affect your individual tax
return and the many variations in state and local tax regulations, we recommend
that you consult your tax advisor for specific guidance.

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Fund's
investment advisory agreement (the "Agreement"). The Investment Company Act of
1940, as amended, requires that the Board request and evaluate, and that the
Manager provide, such information as may be reasonably necessary to evaluate the
terms of the Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information, that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services by the Manager and its affiliates,
(v) the extent to which economies of scale are realized as the Fund grows and
whether fee levels reflect these economies of scale for Fund investors and (vi)
other benefits to the Manager from its relationship with the Fund. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE AND EXTENT OF SERVICES. The Board considered information on the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel that provide such services. The Manager's duties
include providing the Fund with the services of the portfolio manager and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing, and supervising
the activities of, all administrative and clerical personnel that are necessary
in order to provide effective corporate administration for the Fund; compiling
and maintaining records with respect to the Fund's operations; preparing and
filing reports required by the Securities and Exchange Commission; preparing
periodic reports regarding the operations of the Fund for its shareholders;
preparing proxy materials for shareholder meetings; and preparing the
registration statements required by Federal and state securities laws for the
sale of the Fund's shares. The Manager also provides the Fund with office space,
facilities and equipment.


                  48 | OPPENHEIMER CONVERTIBLE SECURITIES FUND


      QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that are available to the
Fund. The Board took account of the facts that the Manager has had over forty
years of experience as an investment adviser and that its assets under
management rank it among the top mutual fund managers in the United States. The
Board evaluated the Manager's administrative, accounting, legal and compliance
services, and information the Board has received regarding the experience and
professional qualifications of the Manager's personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Edward
Everett and the Manager's Growth investment team and analysts. Mr. Everett has
had over 13 years of experience managing equity investments. The Board members
also considered their experiences with the Manager and its officers and other
personnel through their service as directors or trustees of the Fund and other
funds advised by the Manager. The Board considered information regarding the
quality of services provided by affiliates of the Manager, which it also reviews
at other times during the year in connection with the renewal of the Fund's
service agreements. In light of the foregoing, the Board concluded that the Fund
benefits from the services provided under the Agreement as a result of the
Manager's experience, reputation, personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each Board meeting, including comparative performance information.
The Board also reviewed information, prepared by the Manager and by the
independent consultant, comparing the Fund's historical performance to relevant
market indices and to the performance of other convertible securities funds
advised by other investment advisers. The Board noted that the Fund's three-year
and five-year performance were below its peer group average and that its
one-year and ten-year performance were disappointing.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The
independent consultant provided comparative data in regard to the fees and
expenses of the Fund, other convertible securities funds and other funds with
comparable asset levels and distribution features. The Board noted that the
Fund's contractual and actual management fees and total expenses are lower than
its peer group average. The Board also evaluated to what extent the fees charged
and the services provided to the Fund are comparable to the fees and services
for other clients or accounts advised by the Manager.

ADVISORY AGREEMENT  Unaudited/Continued
- --------------------------------------------------------------------------------

      ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Fund, to what extent
those economies of scale benefit the Fund shareholders and the current level of
Fund assets in relation to the Fund's breakpoint schedule for its management
fees. The Board considered that the Fund has not experienced recent asset growth
and that, based on current asset levels, the Fund has passed its last management
fee breakpoint.

      BENEFITS TO THE MANAGER. The Board considered information regarding the
Manager's costs in serving as the Fund's investment adviser, including the costs
associated with the personnel and systems necessary to manage the Fund, and
information regarding the Manager's profitability from its relationship with the
Fund. The Board considered that the Manager must be able to pay and retain
experienced professional personnel at competitive rates to provide services to
the Fund and that maintaining the financial viability of the Manager is
important in order for the Manager to continue to provide significant services
to the Fund and its shareholders. In addition to considering the profits
realized by the Manager, the Board considered information regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager's affiliates for services
provided and research provided to the Manager in connection with permissible
brokerage arrangements (soft dollar arrangements).

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and the independent Trustees. Fund counsel is independent of the
Manager within the meaning and intent of the Securities and Exchange Commission
Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
concluded that the nature, extent and quality of the services provided to the
Fund by the Manager are a benefit to the Fund and in the best interest of the
Fund's shareholders and that the amount and structure of the compensation
received by the Manager and its affiliates are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the advisory
agreement for another year. In arriving at this decision, the Board did not
single out any factor or factors as being more important than others, but
considered all of the factors together. The Board judged the terms and
conditions of the advisory agreement, including the management fee, in light of
all of the surrounding circumstances.

THE FUND'S AUDIT COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Audit Committee (the "Committee") will evaluate potential Board
      candidates to assess their qualifications. The Committee shall have the
      authority, upon approval of the Board, to retain an executive search firm
      to assist in this effort. The Committee may consider recommendations by
      business and personal contacts of current Board members and by executive
      search firms which the Committee may engage from time to time and may also
      consider shareholder recommendations. The Committee may consider the
      advice and recommendation of the Funds' investment manager and its
      affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is an "interested person" as defined in
      the Investment Company Act of 1940; and whether the individual would be
      deemed an "audit committee financial expert" within the meaning of
      applicable SEC rules. The Committee also considers whether the
      individual's background, skills, and experience will complement the
      background, skills, and experience of other nominees and will contribute
      to the Board. There are no differences in the manner in which the
      Committee evaluates nominees for trustees based on whether the nominee is
      recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where



      required, to shareholders. Recommendations for trustee nominees should, at
      a minimum, be accompanied by the following:

      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.

ITEM 11. CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of December 31, 2005, the registrant's principal executive
officer and principal financial officer found the registrant's disclosure
controls and procedures to provide reasonable assurances that information
required to be disclosed by the registrant in the reports that it files under
the Securities Exchange Act of 1934 (a) is accumulated and communicated to
registrant's management, including its principal executive officer and principal
financial officer, to allow timely decisions regarding required disclosure, and
(b) is recorded, processed, summarized and reported, within the time periods
specified in the rules and forms adopted by the U.S. Securities and Exchange
Commission.



There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.

(a)   (1)   Exhibit attached hereto.

      (2)   Exhibits attached hereto.

      (3)   Not applicable.

(b)   Exhibit attached hereto.
