NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

Balanced Portfolio Managers' Commentary

The AMT Balanced Portfolio ended the first half of 2004 with a gain of 3.92%, as
the market began rewarding stocks with solid business fundamentals as opposed to
unproven growth prospects, a trend that favored our equity investment process.
The bond market remained challenging, but our conservative investment style
preserved capital on the bond side of the portfolio.

The largest contribution to relative performance on the equity portion came from
stock selection in the information technology, consumer discretionary and
financial sectors. Stocks that did well in IT included companies that develop
and provide specialized technologies to businesses such as Zebra Technologies.
Within consumer discretionary, our emphasis in entertainment and leisure and
specialty retail companies were some of the primary reasons for this
outperformance with Royal Caribbean Cruises and PETsMART both performing well.
Within the financials sector, Capital One Financial, First Marblehead, and
Investors Financial Services were all strong performers, as they represent less
interest rate sensitive names within that sector.

In the aggregate, our equity sector allocation was slightly negative on a
year-to-date basis, with our underweight position in both consumer staples and
healthcare accounting for much of the underperformance.

Even though we are not pessimistic in terms of the overall economy and
inflation, we are not optimistic in terms of near-term stock performance. We
expect equities to struggle as profit growth slows, interest rates increase, and
the Presidential election remains tight. Over the past six years, the S&P 500 is
essentially flat in price while earnings have increased by a third. The market's
forward P/E has collapsed from 21 to 16 during this period. However, the stock
market is still not cheap, since a P/E of 16 is the long-term average. We
believe P/Es will continue to wilt in the heat of the summer months.
Uncertainties about next year's economy will most likely increase as more
difficult earnings comparisons will begin this quarter. If fears become more
intense and investors overreact, we expect poor near-term equity performance to
provide a platform for better equity performance in the latter part of this
year.

We seek to continue to position the portfolio with tilts toward lower volatility
stocks in higher quality companies with lower earnings variability. As interest
rates move higher and growth rates slow, we believe that companies with
financial strength should be favored.

On the bond side of the portfolio, at the beginning of 2004, we had a relatively
conservative duration, moderately below the duration of the benchmark index. The
portfolio's defensive posture was a reflection of our recognition that low bond
yields provide only a thin cushion to offset potential price declines associated
with the strengthening economy. We maintained the portfolio's conservative
positioning throughout the reporting period, a stance that helped preserve
shareholder capital following the surprisingly strong March employment report
and the Federal Reserve's anticipated interest rate hike in June.

We employed shifts in sector allocation to take advantage of evolving
opportunities in the market. Over the reporting period, we reduced our
allocation to corporate securities from 22.4% of the overall portfolio at the
beginning of the period to 17.3% at the end of June. We also steadily increased
our allocation to U.S. Treasury Securities from 8.8% of the overall portfolio to
18.8% at the end of June, which helped to maintain the portfolio's high credit
quality. These changes are consistent with the conservative structuring of the
portfolio.

As expected, the Federal Reserve Board's Open Market Committee took action by
moving the Fed Funds target rate up 0.25% at its June 30 meeting. In the past,
Fed Chairman Alan Greenspan has employed a measured approach to adjusting the
target rate, taking small discrete steps and then patiently waiting to evaluate
the impact on the economy before proceeding further. In his commentary, Mr.
Greenspan has hinted that the Fed will use a similar approach in the coming
months. We will continue to evaluate these factors and adjust the portfolio
accordingly.

As interest rates rise and additional opportunities become more attractive, we
will once again reach out on the risk spectrum in search of ways to create
value in the fund.

Sincerely,

                             PORTFOLIO CO-MANAGERS

1. 11.95%, 1.59%, and 7.37% were the average annual total returns for the 1-, 5-
and 10-year periods ended June 30, 2004. Neuberger Berman Management Inc.
("NBMI") has agreed to absorb certain expenses of the AMT Portfolios. Without
this arrangement, which is subject to change, the total returns of the
Portfolios would be less. Total return includes reinvestment of dividends and
capital gain distributions. Performance data quoted represent past performance
and the investment return and principal value of an investment will fluctuate so
that the shares, when redeemed, may be worth more or less than original cost.
Current performance may be lower or higher than the performance data quoted. For
performance data current to the most recent month end, please visit www.nb.com/
amtperformance. The performance information does not reflect fees and expenses
of the variable annuity and variable life insurance policies or the pension
plans whose proceeds are invested in the portfolio.

2. The Russell Midcap[RegTM] Growth Index measures the performance of those
Russell Midcap[RegTM] Index companies with higher price-to-book ratios and
higher forecasted growth values. The Russell Midcap Index measures the
performance of the 800 smallest companies in the Russell 1000[RegTM] Index,
which represents approximately 27% of the total market capitalization of the
Russell 1000 Index (which, in turn, consists of the 1,000 largest U.S.
companies, based on market capitalization). The S&P 500 Index is widely regarded
as the standard for measuring large-cap U.S. stock market performance and
includes a representative sample of leading companies in leading industries. The
Merrill Lynch 1-3 Year Treasury Index is an unmanaged total return market value
index consisting of all coupon-bearing U.S. Treasury publicly placed debt
securities with maturities between 1 to 3 years. Please note that indices do not
take into account any fees and expenses of investing in the individual
securities that they track, and that individuals cannot invest directly in any
index. Data about the performance of these indices are prepared or obtained by
NBMI and include reinvestment of all dividends and capital gain distributions.
The Portfolio may invest in many securities not included in the above-described
indices.

Any ratios or other measurements using a factor of forecasted earnings of a
company discussed herein are based on consensus estimates, not Neuberger
Berman's own projections, and they may or may not be realized. In addition, any
revision to a forecast could affect the market price of a security. By quoting
them herein, Neuberger Berman does not offer an opinion as to the accuracy of
and does not guarantee these forecasted numbers.

Notes to Schedule of Investments Balanced Portfolio

+    Investments in equity securities by the Fund are valued at the latest sales
     price where that price is readily available; equity securities for which no
     sales were reported, unless otherwise noted, are valued at the mean between
     the closing bid and asked prices. Securities traded primarily on the NASDAQ
     Stock Market are normally valued by the Fund at the NASDAQ Official Closing
     Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most
     recently reported price as of 4:00:02 p.m., Eastern time, unless that price
     is outside the range of the "inside" bid and asked prices (i.e., the bid
     and asked prices that dealers quote to each other when trading for their
     own accounts); in that case, NASDAQ will adjust the price to equal the
     inside bid or asked price, whichever is closer. Because of delays in
     reporting trades, the NOCP may not be based on the price of the last trade
     to occur before the market closes. Investments in debt securities by the
     Fund are valued daily by obtaining bid price quotations from independent
     pricing services on all securities available in each service's data base.
     For all other debt securities requiring daily quotations, bid prices are
     obtained from principal market makers in those securities. The Fund values
     all other securities by a method the Board of Trustees of Neuberger Berman
     Advisers Management Trust (the "Board") believes accurately reflects fair
     value. Numerous factors may be considered when determining the fair value
     of a security, including available analyst, media or other reports, trading
     in futures or ADRs and whether the issuer of the security being fair valued
     has other securities outstanding. Foreign security prices are furnished by
     independent quotation services expressed in local currency values. Foreign
     security prices are translated from the local currency into U.S. dollars
     using the exchange rate as of 12:00 p.m., Eastern time. The Board has
     approved the use of FT Interactive Data Corporation ("FT Interactive") to
     assist in determining the fair value of the Fund's foreign equity
     securities in the wake of certain significant events. Specifically, when
     changes in the value of a certain index suggest that the closing prices on
     the foreign exchanges no longer represent the amount that the Fund could
     expect to receive for those securities, FT Interactive will provide
     adjusted prices for certain foreign equity securities based on an analysis
     showing historical correlations between the prices of those securities and
     changes in the index. In the absence of precise information about the
     market values of these foreign securities as of the close of the New York
     Stock Exchange, the Board has determined on the basis of available data
     that prices adjusted in this way are likely to be closer to the prices the
     Fund could realize on a current sale than are the prices of those
     securities established at the close of the foreign markets in which the
     securities primarily trade. However, fair value prices are necessarily
     estimates, and there is no assurance that such a price will be at or close
     to the price at which the security next trades. Short-term debt securities
     with less than 60 days until maturity may be valued at cost which, when
     combined with interest earned, approximates market value.

#    At cost, which approximates market value.

##   At June 30, 2004, the cost of investments for U.S. Federal income tax
     purposes was $80,114,861. Gross unrealized appreciation of investments was
     $12,176,784 and gross unrealized depreciation of investments was
     $1,072,924, resulting in net unrealized appreciation of $11,103,860, based
     on cost for U.S. Federal income tax purposes.

**   Security exempt from registration under the Securities Act of 1933. These
     securities may be resold in transactions exempt from registration, normally
     to qualified institutional buyers under Rule 144A. At June 30, 2004, these

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     Notes to Financial Statements Balanced Portfolio

     Note A--Summary of Significant Accounting Policies:

1    General: Balanced Portfolio (the "Fund") is a separate operating series of
     Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware
     statutory trust organized pursuant to a Trust Instrument dated May 23,
     1994. The Trust is currently comprised of ten separate operating series
     (each a "Series," collectively, the "Funds") each of which (except Focus
     Portfolio) is diversified. The Trust is registered as an open-end
     management investment company under the Investment Company Act of 1940, as
     amended, and its shares are registered under the Securities Act of 1933, as
     amended. The Fund currently offers only Class I shares. The Board of
     Trustees of the Trust may establish additional series or classes of shares
     without the approval of shareholders.

     The assets of each Series belong only to that Series, and the liabilities
     of each Series are borne solely by that Series and no other.

     The preparation of financial statements in accordance with accounting
     principles generally accepted in the United States requires Neuberger
     Berman Management Inc. ("Management") to make estimates and assumptions at
     the date of the financial statements. Actual results could differ from
     those estimates.

2    Portfolio valuation: Investment securities are valued as indicated in the
     notes following the Schedule of Investments.

3    Foreign currency translation: The accounting records of the Fund are
     maintained in U.S. dollars. Foreign currency amounts are translated into
     U.S. dollars using the exchange rate as of 12:00 p.m., Eastern time, to
     determine the value of investments, other assets and liabilities. Purchase
     and sale prices of securities, and income and expenses, are translated into
     U.S. dollars at the prevailing rate of exchange on the respective dates of
     such transactions. Net unrealized foreign currency gain (loss) arises from
     changes in the value of assets and liabilities, other than investments in
     securities, as a result of changes in exchange rates and is stated
     separately in the Statement of Operations.

4    Securities transactions and investment income: Securities transactions are
     recorded on a trade date basis. Dividend income is recorded on the
     ex-dividend date or, for certain foreign dividends, as soon as the Fund
     becomes aware of the dividends. Non-cash dividends included in dividend
     income, if any, are recorded at the fair market value of the securities
     received. Interest income, including accretion of original issue discount,
     where applicable, and accretion of market discount on long-term bonds and
     short-term investments, is recorded on the accrual basis. Realized gains
     and losses from securities transactions and foreign currency transactions
     are recorded on the basis of identified cost and stated separately in the
     Statement of Operations.

5    Forward foreign currency contracts: The Fund may enter into forward foreign
     currency contracts ("contracts") in connection with planned purchases or
     sales of securities to hedge the U.S. dollar value of portfolio securities
     denominated in a foreign currency. The gain or loss arising from the
     difference between the original contract price and the closing price of
     such contract is included in net realized gains or losses on foreign
     currency transactions. Fluctuations in the value of forward foreign
     currency contracts


                                       15





Notes to Financial Statements Balanced Portfolio cont'd

     are recorded for financial reporting purposes as unrealized gains or losses
     by the Fund. The Fund has no specific limitation on the percentage of
     assets which may be committed to these types of contracts. The Fund could
     be exposed to risks if a counter party to a contract were unable to meet
     the terms of its contract or if the value of the foreign currency changes
     unfavorably. The U.S. dollar value of foreign currency underlying all
     contractual commitments held by the Fund is determined using forward
     foreign currency exchange rates supplied by an independent pricing service.

6    Federal income taxes: The Funds are treated as separate entities for U.S.
     Federal income tax purposes. It is the policy of the Fund to continue to
     qualify as a regulated investment company by complying with the provisions
     available to certain investment companies, as defined in applicable
     sections of the Internal Revenue Code, and to make distributions of
     investment company taxable income and net capital gains (after reduction
     for any amounts available for U.S. Federal income tax purposes as capital
     loss carryforwards) sufficient to relieve it from all, or substantially
     all, U.S. Federal income taxes. Accordingly, the Fund paid no U.S. Federal
     income taxes and no provision for U.S. Federal income taxes was required.

7    Dividends and distributions to shareholders: The Fund may earn income, net
     of expenses, daily on its investments. Income dividends and distributions
     from net realized capital gains, if any, generally are distributed in
     October. Income dividends and capital gain distributions to shareholders
     are recorded on the ex-dividend date. To the extent the Fund's net realized
     capital gains, if any, can be offset by capital loss carryforwards
     ($28,845,814 and $13,734,010 expiring in 2009 and 2010, respectively,
     determined as of December 31, 2003), it is the policy of the Fund not to
     distribute such gains.

     Under current tax law, certain capital and net foreign currency losses
     realized after October 31 within the taxable year may be deferred and
     treated as occurring on the first day of the following tax year. For the
     year ended December 31, 2003, the Fund elected to defer $604,724 of net
     capital and currency losses arising between November 1, 2003 and December
     31, 2003.

     The Fund distinguishes between dividends on a tax basis and a financial
     reporting basis and only distributions in excess of tax basis earnings and
     profits are reported in the financial statements as a tax return of
     capital. Differences in the recognition or classification of income between
     the financial statements and tax earnings and profits which result in
     temporary over-distributions for financial statement purposes are
     classified as distributions in excess of net investment income or
     accumulated net realized gains in the components of net assets on the
     Statement of Assets and Liabilities.

     The tax character of distributions paid during the years ended December 31,
     2003 and 2002 was as follows:



     Distributions Paid From:

                      Ordinary Income                      Total

                     2003            2002            2003            2002
               $1,410,014       $2,524,587     $1,410,014       $2,524,587


                                       16





      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     As of December 31, 2003, the components of distributable earnings
     (accumulated losses) on a U.S. Federal income tax basis were as follows:


                             Unrealized
          Undistributed    Appreciation    Loss Carryforwards
        Ordinary Income   (Depreciation)        and Deferrals           Total

               $989,969      $9,998,360          $(43,184,548)   $(32,196,219)


     The difference between book basis and tax basis is attributable primarily
     to foreign bond bifurcation, the tax deferral of losses on wash sales, post
     October losses, and amortization of bond premiums.

8    Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
     tax authorities, net of refunds recoverable.

9    Expense allocation: Certain expenses are applicable to multiple funds.
     Expenses directly attributable to a Series are charged to that Series.
     Expenses of the Trust that are not directly attributed to a Series are
     allocated among the Funds, on the basis of relative net assets, except
     where a more appropriate allocation of expenses to each of the Funds can
     otherwise by made fairly. Expenses borne by the complex of related
     investment companies, which includes open-end and closed-end investment
     companies for which Management serves as investment manager, that are not
     directly attributed to a Series or the Trust, are allocated among the Fund
     and the other investment companies in the complex or series thereof, on the
     basis of relative net assets, except where a more appropriate allocation of
     expenses to each investment company in the complex or series thereof can
     otherwise be made fairly.

10   Financial futures contracts: The Fund may buy and sell financial futures
     contracts to hedge against changes in securities prices resulting from
     changes in prevailing interest rates. At the time the Fund enters into a
     financial futures contract, it is required to deposit with its custodian a
     specified amount of cash or liquid securities, known as "initial margin,"
     ranging upward from 1.1% of the value of the financial futures contract
     being traded. Each day, the futures contract is valued at the official
     settlement price of the board of trade or U.S. commodity exchange on which
     such futures contract is traded. Subsequent payments, known as "variation
     margin," to and from the broker are made on a daily basis as the market
     price of the financial futures contract fluctuates. Daily variation margin
     adjustments, arising from this "mark to market," are recorded by the Fund
     as unrealized gains or losses.

     Although some financial futures contracts by their terms call for actual
     delivery or acceptance of financial instruments, in most cases the
     contracts are closed out prior to delivery by offsetting purchases or sales
     of matching financial futures contracts. When the contracts are closed, the
     Fund recognizes a gain or loss. Risks of entering into futures contracts
     include the possibility there may be an illiquid market and/or a change in
     the value of the contract may not correlate with changes in the value of
     the underlying securities.

     For U.S. Federal income tax purposes, the futures transactions undertaken
     by the Fund may cause the Fund to recognize gains or losses from marking to
     market even though its positions have not been sold or terminated, may
     affect the character of the gains or losses recognized as long-term or
     short-term, and may affect the timing of some capital gains and losses
     realized by the Fund. Also, the Fund's losses on


                                       17





Notes to Financial Statements Balanced Portfolio cont'd

     transactions involving futures contracts may be deferred rather than being
     taken into account currently in calculating the Fund's taxable income.

     During the six months ended June 30, 2004, the Fund entered into various
     financial futures contracts. At June 30, 2004, open positions in financial
     futures contracts were as follows:

                                                                    Unrealized
         Expiration                   Open Contracts   Position   Depreciation

     September 2004   50 U.S. Treasury Notes, 5 Year      Short        $40,000


     At June 30, 2004, the Fund had deposited $50,000 in U.S. Treasury Notes,
     3.25%, due 1/15/09, in a segregated account to cover margin requirements on
     open financial futures contracts.

11   Security lending: Pursuant to an Exemptive Order issued by the Securities
     and Exchange Commission, the Fund entered into a Securities Lending
     Agreement ("Agreement") with Neuberger Berman, LLC ("Neuberger") on April
     17, 2003. Securities loans involve certain risks in the event a borrower
     should fail financially, including delays or inability to recover the lent
     securities or foreclose against the collateral. The investment manager,
     under the general supervision of the Trust's Board of Trustees, monitors
     the creditworthiness of the parties to whom the Fund makes security loans.
     The Fund will not lend securities on which covered call options have been
     written, or lend securities on terms which would prevent the Fund from
     qualifying as a regulated investment company. The Fund receives cash
     collateral equal to at least 102% of the current market value of the loaned
     securities. The Fund invests the cash collateral in the N&B Securities
     Lending Quality Fund, LLC, which is managed by State Street Bank and Trust
     Company ("State Street") pursuant to guidelines approved by the Trust's
     investment manager. Neuberger guaranteed minimum revenue to the Fund under
     the Agreement, and received a portion of any revenue earned in excess of
     the guaranteed amount as a lending agency fee.

     The Agreement has been renewed and approved by the Board of Trustees as of
     July 1, 2004 with substantially the same terms. Under this current
     Agreement, Neuberger guarantees minimum revenue to the Fund and receives
     any revenue earned in excess of the guaranteed amount as a lending agency
     fee.

     At June 30, 2004, the Fund had not paid Neuberger any fees under the
     Agreement.

     Income earned on the securities loaned, if any, is reflected in the
     Statement of Operations under the caption Income from securities
     loaned-net.

12   Repurchase agreements: The Fund may enter into repurchase agreements with
     institutions that the Fund's investment manager has determined are
     creditworthy. Each repurchase agreement is recorded at cost. The Fund
     requires that the securities purchased in a repurchase transaction be
     transferred to the custodian in a manner sufficient to enable the Fund to
     assert a perfected security interest in those securities in the event of a
     default under the repurchase agreement. The Fund monitors, on a daily
     basis, the value of the securities transferred to ensure that their value,
     including accrued interest, is greater than amounts owed to the Fund under
     each such repurchase agreement.

13   Transactions with other funds managed by Neuberger Berman Management Inc.:
     Pursuant to an Exemptive Order issued by the Securities and Exchange
     Commission, the Fund may invest in the Neuberger Berman Institutional Cash
     Fund (the "Cash Fund"), a fund managed by Management and


                                       18





      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     having the same Board members as the Fund. The Cash Fund seeks to provide
     as high a level of current income as is consistent with the preservation of
     capital and the maintenance of liquidity. For any cash that the Fund
     invests in the Cash Fund, Management waives a portion of its management fee
     equal to the management fee it receives from the Cash Fund on those assets.
     For the six months ended June 30, 2004, such waived fees amounted to $199.
     For the six months ended June 30, 2004, income earned on this investment
     amounted to $1,498 and is reflected in the Statement of Operations under
     the caption Income from investments in affiliated issuers.

     Note B--Management Fees, Administration Fees, Distribution Arrangements,
     and Other Transactions With Affiliates:

     Fund shares are issued and redeemed in connection with investments in and
     payments under certain variable annuity contracts and variable life
     insurance policies issued through separate accounts of life insurance
     companies and are also offered directly to qualified pension and retirement
     plans.

     The Fund retains Management as its investment manager under a Management
     Agreement. For such investment management services, the Fund pays
     Management a fee at the annual rate of 0.55% of the first $250 million of
     the Fund's average daily net assets, 0.525% of the next $250 million, 0.50%
     of the next $250 million, 0.475% of the next $250 million, 0.45% of the
     next $500 million, 0.425% of the next $2.5 billion, and 0.40% of average
     daily net assets in excess of $4 billion.

     The Fund retains Management as its administrator under an Administration
     Agreement. The Fund pays Management an administration fee at the annual
     rate of 0.30% of its average daily net assets under this agreement.
     Additionally, Management retains State Street as its sub-administrator
     under a Sub-Administration Agreement. Management pays State Street a fee
     for all services received under the agreement.

     The Trustees of the Trust adopted a non-fee distribution plan for the Fund.

     Management has contractually undertaken through December 31, 2007 to
     reimburse the Fund for its operating expenses (excluding the fees payable
     to Management, interest, taxes, brokerage commissions, extraordinary
     expenses, and transaction costs) ("Operating Expenses") which exceed, in
     the aggregate, 1.00% per annum of its average daily net assets (the
     "Expense Limitation"). For the six months ended June 30, 2004, no
     reimbursement to the Fund was required. The Fund has agreed to repay
     Management through December 31, 2010 for its excess Operating Expenses
     previously reimbursed by Management, so long as its annual Operating
     Expenses during that period do not exceed its Expense Limitation, and the
     repayment is made within three years after the year in which Management
     issued the reimbursement. During the six months ended June 30, 2004, there
     was no reimbursement to Management. At June 30, 2004, the Fund has no
     contingent liability to Management under the agreement.

     On October 31, 2003, Management and Neuberger, a member firm of the New
     York Stock Exchange and sub-adviser to the Fund, became indirect
     wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a
     publicly-owned holding company. Neuberger is retained by Management to
     furnish it with investment recommendations and research information without
     added cost to the Fund. Several

Notes to Financial Statements Balanced Portfolio cont'd

     individuals who are officers and/or Trustees of the Trust are also
     employees of Neuberger and/or Management.

     On July 1, 2003, the Fund entered into a commission recapture program,
     which enables it to pay some of its operational expenses by recouping a
     portion of the commissions it pays to a broker that is not a related party
     of the Fund. Expenses paid through this program may include costs of
     custodial, transfer agency or accounting services. For the six months ended
     June 30, 2004, the impact of this arrangement was a reduction of $5,004.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. The impact of this arrangement, reflected in the Statement of
     Operations under the caption Custodian fees, was a reduction of $79.

     Note C--Securities Transactions:

     Cost of purchases and proceeds of sales and maturities of long-term
     securities (excluding short-term securities, financial futures contracts,
     and foreign currency contracts) for the six months ended June 30, 2004 were
     as follows:

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     Note E--Line of Credit:

     At June 30, 2004, the Fund was a participant in a single committed,
     unsecured $150,000,000 line of credit with State Street, to be used only

     for temporary or emergency purposes. Interest is charged on borrowings
     under this agreement at the overnight Federal Funds Rate plus 0.50% per
     annum. A facility fee of 0.10% per annum of the available line of credit is
     charged, of which the Fund has agreed to pay its pro rata share, based on
     the ratio of its individual net assets to the net assets of all
     participants at the time the fee is due and payable. The fee is paid
     quarterly in arrears. No compensating balance is required. Other investment
     companies managed by Management also participate in this line of credit on
     the same terms. Because several investment companies participate, there is
     no assurance that the Fund will have access to the entire $150,000,000 at
     any particular time. The Fund had no loans outstanding pursuant to this
     line of credit at June 30, 2004, nor had the Fund utilized this line of
     credit at any time prior to that date.

     Note F--Unaudited Financial Information:

     The financial information included in this interim report is taken from the
     records of the Fund without audit by independent auditors. Annual reports
     contain audited financial statements.

Notes to Financial Highlights Balanced Portfolio

+     The per share amounts and ratios which are shown reflect income and
      expenses, including the Fund's proportionate share of AMT Balanced
      Investment's income and expenses through April 30, 2000 under the prior
      master/feeder fund structure.

++    Total return based on per share net asset value reflects the effects of
      changes in net asset value on the performance of the Fund during each
      fiscal period and assumes dividends and other distributions, if any, were
      reinvested. Results represent past performance and do not guarantee future
      results. Current returns may be lower or higher than the performance data
      quoted. Investment returns and principal may fluctuate and shares when
      redeemed may be worth more or less than original cost. Total return would
      have been lower if Management had not waived certain expenses. The total
      return information shown does not reflect charges and other expenses that
      apply to the separate account or the related insurance policies, and the
      inclusion of these charges and other expenses would reduce the total
      return for all fiscal periods shown. Performance data current to the most
      recent month-end are available at www.nb.com.

#     The Fund is required to calculate an expense ratio without taking into
      consideration any expense reductions related to expense offset and
      commission recapture arrangements.

++    The per share amounts which are shown have been computed based on the
      average number of shares outstanding during each fiscal period.

[sec] After waiver of a portion of the investment management fee. Had the
      investment manager not undertaken such action, the annualized ratios of
      net expenses to average daily net assets would have been:

Y     For fiscal years ended after December 31, 2000, funds are required by the
      American Institute of Certified Public Accountants to amortize premiums
      and discounts on fixed income securities. Accordingly, for the year ended
      December 31, 2001, the per share amounts and ratios shown decreased or
      increased as follows:

                                                                   Year Ended

Fasciano Portfolio Manager's Commentary
- ---------------------------------------

The Fasciano Portfolio underperformed its benchmark, the Russell 2000 Index, as
small-cap stocks made good progress in the first half of 2004.(2)

The market environment in this reporting period was much more friendly to our
style of investing than was last year's. In 2003, the portfolio generated a
respectable double-digit gain, but still trailed its benchmark. In general, our
holdings had met our fundamental expectations, but investors were considerably
more excited by the smaller, more speculative stocks that drove the Russell
2000's returns. In the first half of 2004, however, investors began migrating
out of last year's big winners and into the more established, higher quality
companies that we favor. This has translated into much better returns versus
our benchmark.

In the first half of 2004, our industrials sector investments had the most
favorable impact on returns. We were overweighted in industrials and our
holdings gained nearly twice as much as the benchmark sector component returns.
Five industrial companies appeared on our top-ten performance list. Landstar
Systems is a trucking firm that doesn't own any trucks. Landstar simply books
shipping business from its corporate clients and for a fee distributes the
business to independent truckers. Landstar's low overhead business model has
translated into high profit margins and good earnings growth. Kroll is a
business security firm that provides a variety of services including background
checks on prospective employees, forensic accounting, and litigation support.
We thought Kroll was a unique company and insurance giant Marsh & McLennan,
which recently acquired Kroll at a nice premium to our cost, must have thought
so as well. IDEX Corp. is a well-established company in the pump and valve
business that continues to build on a good earnings track record. MSC
Industrial Direct is still a small-cap company, but has become the largest
distributor of maintenance and repair products to the factory floor. The
company's catalog is enormous and their next-day delivery system keeps
attracting new customers. G&K Services is a uniform rental company that has
been a direct beneficiary of new jobs created this year.

Technology holdings made the second largest contribution to returns. Our tech
sector winners included ScanSource, a wholesale distributor of bar code
printers and telephony products, and Plantronics, an innovator in wireless
headsets. ScanSource continues to benefit from its close business relationship
with Zebra Technologies, a leading manufacturer of state-of-the-art bar code
printers. Plantronics' wireless headset business is being boosted by strong
demand in offices and on the road, where government entities in the U.S. and
Europe are passing safety legislation requiring hands-free cellular
telecommunications in the car.

Healthcare was our poorest performing sector. We were equal weighted in
healthcare versus the benchmark, but collectively our healthcare holdings
declined by 5.1% versus a 9.6% gain for the Russell 2000's healthcare
component. Dental supply company Young Innovations was our worst performing
stock. There is nothing wrong with the dental supply business. In fact,
favorable demographics--aging Americans spending more money on dental
care--should continue to promote well above average growth. Young Innovations
stock declined sharply when the


                                        1





company announced it would not offer dealer incentives at the end of the second
quarter, causing its customers to defer purchases. It also announced it would
be consolidating its manufacturing operations. Although over the long term,
this will help the company cut costs and improve profit margins, over the short
term it will result in some additional charges and expenses, which could
negatively impact this year's earnings. Short-term earnings dislocations don't
trouble us and we continue to believe Young Innovations will be a productive
long-term investment. KV Pharmaceuticals also disappointed. Its fiscal fourth
quarter earnings met consensus expectations, but sales were lower than
anticipated. Although we think this is a short-term blip rather than a serious
problem, skittish investors bailed out.

It appears the economy is on a moderate upward trajectory that should foster
decent sales growth. Recent years' cost cutting and productivity gains have
improved profit margins for most companies. So, rising sales should translate
into good earnings growth. This is generally a favorable backdrop for stocks.
Although there are pockets in the small-cap market where future earnings are
not likely to justify current valuations, we are still finding what we believe
are lots of great small growth companies that are under-followed by Wall Street
and under-owned by institutions, and therefore priced attractively relative to
above-average growth prospects. We can never be sure whether these stocks will
reward us over the next quarter or two. However, we are generally confident
that they will contribute to long-term returns.

Sincerely,

                             /s/ Michael F. Fasciano

                               MICHAEL F. FASCIANO
                                PORTFOLIO MANAGER

1. 22.74% and 14.65% were the average annual total returns for the 1-year and
since inception (07/12/02) periods ended June 30, 2004. Neuberger Berman
Management Inc. ("NBMI") has agreed to absorb certain expenses of the AMT
Portfolios. Without this arrangement, which is subject to change, the total
returns of the Portfolios would be less. Total return includes reinvestment of
dividends and capital gain distributions. Performance data quoted represent
past performance and the investment return and principal value of an investment
will fluctuate so that the shares, when redeemed, may be worth more or less
than original cost. Current performance may be lower or higher than the
performance data quoted. For performance data current to the most recent month
end, please visit www.nb.com/amtperformance. The performance information does
not reflect fees and expenses of the variable annuity and variable life
insurance policies or the pension plans whose proceeds are invested in the
portfolio.

2. The Russell 2000[RegTM] Index is an unmanaged index consisting of securities
of the 2,000 issuers having the smallest capitalization in the Russell
3000[RegTM] Index (which measures the performance of the 3,000 largest U.S.
companies based on total market capitalization), representing approximately 8%
of the Russell 3000 total market capitalization. The smallest company's market
capitalization is roughly $117 million. Please note that indices do not take
into account any fees and expenses of investing in the individual securities
that they track, and that individuals cannot invest directly in any index. Data
about the performance of this index are prepared or obtained by NBMI and
include reinvestment of all dividends and capital gain distributions. The
Portfolio may invest in many securities not included in the above-described
index.

Notes to Schedule of Investments Fasciano Portfolio
- ---------------------------------------------------

+   Investments in equity securities by the Fund are valued at the latest sales
    price where that price is readily available; securities for which no sales
    were reported, unless otherwise noted, are valued at the mean between the
    closing bid and asked prices. Securities traded primarily on the NASDAQ
    Stock Market are normally valued by the Fund at the NASDAQ Official Closing
    Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most
    recently reported price as of 4:00:02 p.m., Eastern time, unless that price
    is outside the range of the "inside" bid and asked prices (i.e., the bid and
    asked prices that dealers quote to each other when trading for their own
    accounts); in that case, NASDAQ will adjust the price to equal the inside
    bid or asked price, whichever is closer. Because of delays in reporting
    trades, the NOCP may not be based on the price of the last trade to occur
    before the market closes. The Fund values all other securities by a method
    the Board of Trustees of Neuberger Berman Advisers Management Trust (the
    "Board") believes accurately reflects fair value. Numerous factors may be
    considered when determining the fair value of a security, including
    available analyst, media or other reports, trading in futures or ADRs and
    whether the issuer of the security being fair valued has other securities
    outstanding. Foreign security prices are furnished by independent quotation
    services expressed in local currency values. Foreign security prices are
    translated from the local currency into U.S. dollars using the exchange rate
    as of 12:00 p.m., Eastern time. The Board has approved the use of FT
    Interactive Data Corporation ("FT Interactive") to assist in determining the
    fair value of the Fund's foreign equity securities in the wake of certain
    significant events. Specifically, when changes in the value of a certain
    index suggest that the closing prices on the foreign exchanges no longer
    represent the amount that the Fund could expect to receive for those
    securities, FT Interactive will provide adjusted prices for certain foreign
    equity securities based on an analysis showing historical correlations
    between the prices of those securities and changes in the index. In the
    absence of precise information about the market values of these foreign
    securities as of the close of the New York Stock Exchange, the Board has
    determined on the basis of available data that prices adjusted in this way
    are likely to be closer to the prices the Fund could realize on a current
    sale than are the prices of those securities established at the close of the
    foreign markets in which the securities primarily trade. However, fair value
    prices are necessarily estimates, and there is no assurance that such a
    price will be at or close to the price at which the security next trades.
    Short-term debt securities with less than 60 days until maturity may be
    valued at cost which, when combined with interest earned, approximates
    market value.

#   At cost, which approximates market value.

##  At June 30, 2004, the cost of investments for U.S. Federal income tax
    purposes was $8,466,034. Gross unrealized appreciation of investments was
    $1,221,459 and gross unrealized depreciation of investments was $74,340,
    resulting in net unrealized appreciation of $1,147,119, based on cost for
    U.S. Federal income tax purposes.

*   Non-income producing security.

#   All or a portion of this security is on loan (see Note A of Notes to
    Financial Statements).

@   Neuberger Berman Institutional Cash Fund is also managed by Neuberger Berman
    Management Inc. (see Note A of Notes to Financial Statements).

     Portfolio) is diversified. The Trust is registered as an open-end
     management investment company under the Investment Company Act of 1940, as
     amended (the "1940 Act"), and its shares are registered under the
     Securities Act of 1933, as amended. The Fund currently offers only Class S
     shares. The Board of Trustees of the Trust may establish additional series
     or classes of shares without the approval of shareholders.

     The assets of each Series belong only to that Series, and the liabilities
     of each Series are borne solely by that Series and no other.

     The preparation of financial statements in accordance with accounting
     principles generally accepted in the United States requires Neuberger
     Berman Management Inc. ("Management") to make estimates and assumptions at
     the date of the financial statements. Actual results could differ from
     those estimates.

2    Portfolio valuation: Investment securities are valued as indicated in the
     notes following the Schedule of Investments.

3    Foreign currency translation: The accounting records of the Fund are
     maintained in U.S. dollars. Foreign currency amounts are translated into
     U.S. dollars using the exchange rate as of 12:00 p.m., Eastern time, to
     determine the value of investments, other assets and liabilities. Purchase
     and sale prices of securities, and income and expenses, are translated into
     U.S. dollars at the prevailing rate of exchange on the respective dates of
     such transactions. Net unrealized foreign currency gain (loss) arises from
     changes in the value of assets and liabilities, other than investments in
     securities, as a result of changes in exchange rates and is stated
     separately in the Statement of Operations.

4    Securities transactions and investment income: Securities transactions are
     recorded on a trade date basis. Dividend income is recorded on the
     ex-dividend date or, for certain foreign dividends, as soon as the Fund
     becomes aware of the dividends. Non-cash dividends included in dividend
     income, if any, are recorded at the fair market value of the securities
     received. Interest income, including accretion of original issue discount,
     where applicable, and accretion of discount on short-term investments, is
     recorded on the accrual basis. Realized gains and losses from securities
     transactions and foreign currency transactions are recorded on the basis of
     identified cost and stated separately in the Statement of Operations.

5    Federal income taxes: The Funds are treated as separate entities for U.S.
     Federal income tax purposes. It is the policy of the Fund to continue to
     qualify as a regulated investment company by complying with the provisions
     available to certain investment companies, as defined in applicable
     sections of the Internal Revenue Code, and to make distributions of
     investment company taxable income and net capital gains (after reduction
     for any amounts available for U.S. Federal income tax purposes as capital
     loss


                                       11

     carryforwards) sufficient to relieve it from all, or substantially all,
     U.S. Federal income taxes. Accordingly, the Fund paid no U.S. Federal
     income taxes and no provision for U.S. Federal income taxes was required.

6    Dividends and distributions to shareholders: The Fund may earn income, net
     of expenses, daily on its investments. Income dividends and distributions
     from net realized capital gains, if any, generally are distributed in
     October. Income dividends and capital gain distributions to shareholders
     are recorded on the ex-dividend date. To the extent the Fund's net realized
     capital gains, if any, can be offset by capital loss carryforwards, it is
     the policy of the Fund not to distribute such gains.

     The Fund distinguishes between dividends on a tax basis and a financial
     reporting basis and only distributions in excess of tax basis earnings and
     profits are reported in the financial statements as a tax return of
     capital. Differences in the recognition or classification of income between
     the financial statements and tax earnings and profits which result in
     temporary over-distributions for financial statement purposes are
     classified as distributions in excess of net investment income or
     accumulated net realized gains in the components of net assets on the
     Statement of Assets and Liabilities.

     The tax character of distributions paid during the periods ended December
     31, 2003 and 2002 was as follows:

     Distributions Paid From:

                                                      Long-Term
                             Ordinary Income     Capital Gain           Total
                             2003    2002     2003    2002       2003     2002

                           $2,283   $ --     $ --     $ --     $2,283     $ --

     As of December 31, 2003, the components of distributable earnings
     (accumulated losses) on a U.S. Federal income tax basis were as follows:

                       Undistributed  Undistributed   Unrealized
                          Ordinary      Long-Term    Appreciation
                           Income         Gain      (Depreciation)      Total

                           $4,148        $31,915       $794,607        $830,670

     The difference between book basis and tax basis is attributable primarily
     to net operating losses and the tax deferral of losses on wash sales.

7    Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
     tax authorities, net of refunds recoverable.

8    Expense allocation: Certain expenses are applicable to multiple funds.
     Expenses directly attributable to a Series are charged to that Series.
     Expenses of the Trust that are not directly attributed to a Series are
     allocated among the Funds, on the basis of relative net assets, except
     where a more appropriate allocation of expenses to each of the Funds can
     otherwise be made fairly. Expenses borne by the complex of related
     investment companies, which includes open-end and closed-end investment
     companies for which Management serves as investment manager, that are not
     directly attributed to a Series or the Trust, are allocated among the Fund
     and the other investment companies in the complex or series thereof, on the
     basis of relative net assets, except where a more appropriate allocation of
     expenses to each investment company in the complex or series thereof can
     otherwise be made fairly.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

9    Security lending: Pursuant to an Exemptive Order issued by the Securities
     and Exchange Commission, the Fund entered into a Securities Lending
     Agreement ("Agreement") with Neuberger Berman, LLC ("Neuberger") on April
     17, 2003. Securities loans involve certain risks in the event a borrower
     should fail financially, including delays or inability to recover the lent
     securities or foreclose against the collateral. The investment manager,
     under the general supervision of the Trust's Board of Trustees, monitors
     the creditworthiness of the parties to whom the Fund makes security loans.
     The Fund will not lend securities on which covered call options have been
     written, or lend securities on terms which would prevent the Fund from
     qualifying as a regulated investment company. The Fund receives cash
     collateral equal to at least 102% of the current market value of the loaned
     securities. The Fund invests the cash collateral in the N&B Securities
     Lending Quality Fund, LLC, which is managed by State Street Bank and Trust
     Company ("State Street") pursuant to guidelines approved by the Trust's
     investment manager. Neuberger received a portion of the revenue under the
     Agreement as a lending agency fee.

     The Agreement has been renewed and approved by the Board of Trustees as of
     July 1, 2004 with substantially the same terms. Under this current
     Agreement, Neuberger guarantees minimum revenue to the Fund and receives
     any revenue earned in excess of the guaranteed amount as a lending agency
     fee.

     At June 30, 2004, the Fund had not paid Neuberger any fees under the
     Agreement.

     Income earned on the securities loaned, if any, is reflected in the
     Statement of Operations under the caption Income from securities
     loaned-net.

     10 Transactions with other funds managed by Neuberger Berman Management
     Inc.: Pursuant to an Exemptive Order issued by the Securities and Exchange
     Commission, the Fund may invest in the Neuberger Berman Institutional Cash
     Fund (the "Cash Fund"), a fund managed by Management and having the same
     Board members as the Fund. The Cash Fund seeks to provide as high a level
     of current income as is consistent with the preservation of capital and the
     maintenance of liquidity. For any cash that the Fund invests in the Cash
     Fund, Management waives a portion of its management fee equal to the
     management fee it receives from the Cash Fund on those assets. For the six
     months ended June 30, 2004 such waived fees amounted to $437. For the six
     months ended June 30, 2004, income earned on this investment amounted to
     $3,462 and is reflected in the Statement of Operations under the caption
     Income from investments in affiliated issuers.

     Note B--Management Fees, Administration Fees, Distribution Arrangements,
     and Other Transactions With Affiliates:

     Fund shares are issued and redeemed in connection with investments in and
     payments under certain variable annuity contracts and variable life
     insurance policies issued through separate accounts of life insurance
     companies and are also offered directly to qualified pension and retirement
     plans.

     The Fund retains Management as its investment manager under a Management
     Agreement. For such investment management services, the Fund pays
     Management a fee at the annual rate of 0.85% of the first $500 million of
     the Fund's average daily net assets, 0.825% of the next $500 million, 0.80%
     of the next

                                       13





Notes to Financial Statements Fasciano Portfolio cont'd
- -------------------------------------------------------

     $500 million, 0.775% of the next $500 million, 0.75% of the next $500
     million, and 0.725% of average daily net assets in excess of $2.5 billion.

     The Fund retains Management as its administrator under an Administration
     Agreement. The Fund pays Management an administration fee at the annual
     rate of 0.30% of its average daily net assets under this agreement.
     Additionally, Management retains State Street as its sub-administrator
     under a Sub-Administration Agreement. Management pays State Street a fee
     for all services received under the agreement.

     Management acts as agent in arranging for the sale of Fund shares without
     commission and bears advertising and promotion expenses. The Trustees of
     the Trust have adopted a distribution plan (the "Plan") with respect to the
     Fund, pursuant to Rule 12b-1 under the 1940 Act. The Plan provides that, as
     compensation for administrative and other services provided to the Fund,
     Management's activities and expenses related to the sale and distribution
     of the Fund's shares, and ongoing services provided to investors in the
     Fund, Management receives from the Fund a fee at the annual rate of 0.25%
     of its average daily net assets. Management receives this amount to provide
     distribution and shareholder servicing for the Fund and pays a portion of
     it to institutions that provide such services. Those institutions may use
     the payments for, among other purposes, compensating employees engaged in
     sales and/or shareholder servicing. The amount of fees paid by the Fund
     during any year may be more or less than the cost of distribution and other
     services provided to the Fund. NASD rules limit the amount of annual
     distribution fees that may be paid by a mutual fund and impose a ceiling on
     the cumulative distribution fees paid. The Trust's Plan complies with those
     rules.

     Management has contractually undertaken through December 31, 2007 to
     reimburse the Fund for its operating expenses (including the fees payable
     to Management but excluding interest, taxes, brokerage commissions,
     extraordinary expenses, and transaction costs) ("Operating Expenses") which
     exceed, in the aggregate, 1.40% per annum of its average daily net assets
     (the "Expense Limitation"). For the six months ended June 30, 2004, such
     excess expenses amounted to $43,996. The Fund has agreed to repay
     Management through December 31, 2010 for its excess Operating Expenses
     previously reimbursed by Management, so long as its annual Operating
     Expenses during that period do not exceed its Expense Limitation, and the
     repayment is made within three years after the year in which Management
     issued the reimbursement. During the six months ended June 30, 2004, there
     was no reimbursement to Management. At June 30, 2004, the Fund has a
     contingent liability to Management under this agreement of $180,600.

     On October 31, 2003, Management and Neuberger, a member firm of the New
     York Stock Exchange and sub-adviser to the Fund, became indirect
     wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a
     publicly-owned holding company. Neuberger is retained by Management to
     furnish it with investment recommendations and research information without
     added cost to the Fund. Several individuals who are officers and/or
     Trustees of the Trust are also employees of Neuberger and/or Management.

     On July 1, 2003, the Fund entered into a commission recapture program,
     which enables it to pay some of its operational expenses by recouping a
     portion of the commissions it pays to a broker that is not a related party
     of the Fund. Expenses paid through this program may include costs of
     custodial, transfer agency or accounting services. For the six months ended
     June 30, 2004, the impact of this arrangement was a reduction of $361.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     The Fund has an expense offset arrangement in connection with its custodian
     contract. The impact of this arrangement, reflected in the Statement of
     Operations under the caption Custodian fees, was a reduction of $2.

     Note C--Securities Transactions:

     During the six months ended June 30, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $2,222,879 and $382,641,
     respectively.

     During the six months ended June 30, 2004, brokerage commissions on
     securities transactions amounted to $3,288, of which Neuberger received $0,
     Lehman received $662, and other brokers received $2,626.

     Note D--Fund Share Transactions:

     Share activity for the six months ended June 30, 2004 and for the year
     ended December 31, 2003 was as follows:

                                                    For the             For the

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

     Note E--Line of Credit:

     At June 30, 2004, the Fund was a participant in a single committed,
     unsecured $150,000,000 line of credit with State Street, to be used only
     for temporary or emergency purposes. Interest is charged on borrowings
     under this agreement at the overnight Federal Funds Rate plus 0.50% per
     annum. A facility fee of 0.10% per annum of the available line of credit is
     charged, of which the Fund has agreed to pay its pro rata share, based on
     the ratio of its individual net assets to the net assets of all
     participants at the time the fee is due and payable. The fee is paid
     quarterly in arrears. No compensating balance is required. Other investment
     companies managed by Management also participate in this line of credit on
     the same terms. Because several investment companies participate, there is
     no assurance that the Fund will have access to the entire $150,000,000 at
     any particular time. The Fund had no loans outstanding pursuant to this
     line of credit at June 30, 2004, nor had the Fund utilized this line of
     credit at any time prior to that date.

     Note F--Unaudited Financial Information:

     The financial information included in this interim report is taken from the
     records of the Fund without audit by independent auditors. Annual reports
     contain audited financial statements.

Focus Portfolio Managers' Commentary

AMT Focus declined roughly three percent over the first six months of 2004,
underperforming its benchmarks, the Russell 1000 Value Index and the Standard &
Poor's 500 Index.(2)

Portfolio performance this year has been volatile, which is not surprising
given our concentration. Our underperformance year-to-date, while obviously
undesirable, is also not surprising considering our significant outperformance
in 2003, a year in which we returned roughly three times more than our
benchmarks.

Positive portfolio performance continued into the start of the new year, and we
comfortably outperformed the Russell Index through the first three months of
2004. Our financial stocks drove positive absolute and relative returns; our
selection of stocks outperformed Russell sector components. Our consumer credit
companies, such as Capital One Financial, and investment banking and brokerage
stocks, including J.P. Morgan Chase and Citigroup, performed well thanks to
generally sound market conditions, strengthening capital markets activity,
improving credit-quality trends and strong earnings reports. Our one industrial
holding, MemberWorks, also contributed to strong portfolio performance.

Such substantial outperformance is generally unsustainable, however, and at the
start of the second quarter, our portfolio began to retreat as a better-than-
expected employment report ignited concern that the Federal Reserve
would soon raise interest rates, and perhaps, aggressively. While corporations
saw this as a positive sign of an improving economy, investors began to fear
that rising rates would halt the earnings growth of many financial companies.
Rising rates also sparked fears of a slowdown in technology, as did concerns
about high inventory levels, China's future, and the then-approaching seasonal
slowdown in tech. With the majority of our portfolio invested in financials and
information technology, AMT Focus' performance was adversely affected. This
occurred despite the fact that almost all of our companies reported
better-than-expected earnings results.

While our financial companies lost some of the ground they had gained in the
first quarter, they did end the full six-month period with gains. Our
industrial and consumer discretionary holdings, though they detracted in the
second quarter, also contributed positively to absolute and relative
year-to-date returns; our selection of stocks outperformed their index sector
counterparts over the period. Our information technology holdings, on the other
hand, detracted from total return and were the major cause of portfolio
underperformance.

While we are certainly not pleased with the way in which the market has treated
some of our companies, we are long-term investors and remain confident in the
long-term outlook for our portfolio. We realize, of course, that many investors
may have a much shorter investment time horizon.

The fact that many investors are worried over whether companies such as
Citigroup and J.P. Morgan Chase will be able to cope with rising interest rates
has hurt our short-term performance. But we are not worried about whether these
companies' managements are capable of prospering


                                        1





in a period of rising rates; we believe they are. We therefore currently remain
committed to our investments in the group.

We've never been ones to follow the herd. We will continue to do what we've said
we will do, which is to build a portfolio that trades at a discount to the
market and, at the same time, has what we believe to be superior earnings growth
characteristics. The way to do this is to buy companies when they are out of
favor with the market majority: those "under a rock or under a cloud." We are
confident that our strategy will succeed over the long-term--that eventually the
clouds will lift and the sun will come out.

Sincerely,

                                 /s/ Kent Simons

                              PORTFOLIO CO-MANAGERS

1. 33.88% and 45.28% were the average annual total returns for the 1-year and
since inception (08/08/02) periods ended June 30, 2004. Neuberger Berman
Management Inc. ("NBMI") has agreed to absorb certain expenses of the AMT
Portfolios. Without this arrangement, which is subject to change, the total
returns of the Portfolios would be less. Total return includes reinvestment of
dividends and capital gain distributions. Performance data quoted represent
past performance and the investment return and principal value of an investment
will fluctuate so that the shares, when redeemed, may be worth more or less
than original cost. Current performance may be lower or higher than the
performance data quoted. For performance data current to the most recent month
end, please visit www.nb.com/amtperformance. The performance information does
not reflect fees and expenses of the variable annuity and variable life
insurance policies or the pension plans whose proceeds are invested in the
portfolio.

2. The S&P 500 Index is widely regarded as the standard for measuring large-cap
U.S. stock market performance and includes a representative sample of leading
companies in leading industries. The Russell 1000[RegTM] Index measures the
performance of the 1,000 largest companies in the Russell 3000[RegTM]Index
(which measures performance of the 3,000 largest U.S. companies based on total
market capitalization). The Russell 1000 Index represents approximately 92% of
the total market capitalization of the Russell 3000 Index. The Russell 1000
Value Index measures the performance of those Russell 1000 companies with lower
price-to-book ratios and lower forecasted growth values. Please note that
indices do not take into account any fees and expenses of investing in the
individual securities that they track, and that individuals cannot invest
directly in any index. Data about the performance of these indices are prepared
or obtained by NBMI and include reinvestment of all dividends and capital gain
distributions. The Portfolio may invest in many securities not included in the
above-described indices.

The investments for the Portfolio are managed by the same portfolio manager(s)
who manage one or more other mutual funds that have similar names, investment
objectives and investment styles as the Portfolio. You should be aware that the
Portfolio is likely to differ from the other mutual funds in size, cash flow
pattern and tax matters. Accordingly, the holdings and performance of the
Portfolio can be expected to vary from those of the other mutual funds.

The composition, industries and holdings of the Portfolio are subject to
change.

Shares of the separate Portfolios of Neuberger Berman Advisers Management Trust
are sold only through the currently effective prospectus and are not available
to the general public. Shares of this Portfolio may be purchased only by life
insurance companies to be used with their separate accounts that fund variable
annuity and variable life insurance policies and by qualified pension and
retirement plans.

Notes to Schedule of Investments Focus Portfolio

+  Investments in equity securities by the Fund are valued at the latest sales
   price where that price is readily available; securities for which no sales
   were reported, unless otherwise noted, are valued at the mean between the
   closing bid and asked prices. Securities traded primarily on the NASDAQ Stock
   Market are normally valued by the Fund at the NASDAQ Official Closing Price
   ("NOCP") provided by NASDAQ each business day. The NOCP is the most recently
   reported price as of 4:00:02 p.m., Eastern time, unless that price is outside
   the range of the "inside" bid and asked prices (i.e., the bid and asked
   prices that dealers quote to each other when trading for their own accounts);
   in that case, NASDAQ will adjust the price to equal the inside bid or asked
   price, whichever is closer. Because of delays in reporting trades, the NOCP
   may not be based on the price of the last trade to occur before the market
   closes. The Fund values all other securities by a method the Board of
   Trustees of Neuberger Berman Advisers Management Trust (the "Board") believes
   accurately reflects fair value. Numerous factors may be considered when
   determining the fair value of a security, including available analyst, media
   or other reports, trading in futures or ADRs and whether the issuer of the
   security being fair valued has other securities outstanding. Foreign security
   prices are furnished by independent quotation services expressed in local
   currency values. Foreign security prices are translated from the local
   currency into U.S. dollars using the exchange rate as of 12:00 p.m., Eastern
   time. The Board has approved the use of FT Interactive Data Corporation ("FT
   Interactive") to assist in determining the fair value of the Fund's foreign
   equity securities in the wake of certain significant events. Specifically,
   when changes in the value of a certain index suggest that the closing prices
   on the foreign exchanges no longer represent the amount that the Fund could
   expect to receive for those securities, FT Interactive will provide adjusted
   prices for certain foreign equity securities based on an analysis showing
   historical correlations between the prices of those securities and changes in
   the index. In the absence of precise information about the market values of
   these foreign securities as of the close of the New York Stock Exchange, the
   Board has determined on the basis of available data that prices adjusted in
   this way are likely to be closer to the prices the Fund could realize on a
   current sale than are the prices of those securities established at the close
   of the foreign markets in which the securities primarily trade. However, fair
   value prices are necessarily estimates, and there is no assurance that such a
   price will be at or close to the price at which the security next trades.
   Short-term debt securities with less than 60 days until maturity may be
   valued at cost which, when combined with interest earned, approximates market
   value.

#  At cost, which approximates market value.

## At June 30, 2004, the cost of investments for U.S. Federal income tax
   purposes was $936,864. Gross unrealized appreciation of investments was
   $255,426 and gross unrealized depreciation of investments was $24,259,
   resulting in net unrealized appreciation of $231,167, based on cost for U.S.
   Federal income tax purposes.

Notes to Financial Statements Focus Portfolio

Note A--Summary of Significant Accounting Policies:

1 General: Focus Portfolio (the "Fund") is a separate operating series of
Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware statutory
trust organized pursuant to a Trust Instrument dated May 23, 1994. The Trust is
currently comprised of ten separate operating series (each a "Series,"
collectively, the "Funds") each of which (except the Fund) is diversified. The
Trust is registered as an open-end management investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"), and its shares are
registered under the Securities Act of 1933, as amended. The Fund currently
offers only Class S shares. The Board of Trustees of the Trust may establish
additional series or classes of shares without the approval of shareholders.

The assets of each Series belong only to that Series, and the liabilities of
each Series are borne solely by that Series and no other.

The preparation of financial statements in accordance with accounting
principles generally accepted in the United States requires Neuberger Berman
Management Inc. ("Management") to make estimates and assumptions at the date of
the financial statements. Actual results could differ from those estimates.

2 Portfolio valuation: Investment securities are valued as indicated in the
notes following the Schedule of Investments.

3 Foreign currency translation: The accounting records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars using the exchange rate as of 12:00 p.m., Eastern time, to determine
the value of investments, other assets and liabilities. Purchase and sale
prices of securities, and income and expenses, are translated into U.S. dollars
at the prevailing rate of exchange on the respective dates of such
transactions. Net unrealized foreign currency gain (loss) arises from changes
in the value of assets and liabilities, other than investments in securities,
as a result of changes in exchange rates and is stated separately in the
Statement of Operations.

4 Securities transactions and investment income: Securities transactions are
recorded on a trade date basis. Dividend income is recorded on the ex-dividend
date or, for certain foreign dividends, as soon as the Fund becomes aware of
the dividends. Non-cash dividends included in dividend income, if any, are
recorded at the fair market value of the securities received. Interest income,
including accretion of original issue discount, where applicable, and accretion
of discount on short-term investments, is recorded on the accrual basis.
Realized gains and losses from securities transactions and foreign currency
transactions are recorded on the basis of identified cost and stated separately
in the Statement of Operations.

5 Federal income taxes: The Funds are treated as separate entities for U.S.
Federal income tax purposes. It is the policy of the Fund to continue to
qualify as a regulated investment company by complying with the provisions
available to certain investment companies, as defined in applicable sections of
the Internal Revenue Code, and to make distributions of investment company
taxable income and net capital gains (after reduction for any amounts available
for U.S. Federal income tax purposes as capital loss carryforwards) sufficient
to relieve it from all, or substantially all, U.S. Federal income taxes.
Accordingly, the Fund paid no U.S. Federal income taxes and no provision for
U.S. Federal income taxes was required.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

6 Dividends and distributions to shareholders: The Fund may earn income, net of
expenses, daily on its investments. Income dividends and distributions from net
realized capital gains, if any, generally are distributed in October. Income
dividends and capital gain distributions to shareholders are recorded on the
ex-dividend date. To the extent the Fund's net realized capital gains, if any,
can be offset by capital loss carryforwards, it is the policy of the Fund not
to distribute such gains.

Under current tax law, certain capital and net foreign currency losses realized
after October 31 within the taxable year may be deferred and treated as
occurring on the first day of the following tax year. For the year ended
December 31, 2003, the Fund elected to defer $718 of net capital losses arising
between November 1, 2003 and December 31, 2003.

The Fund distinguishes between dividends on a tax basis and a financial
reporting basis and only distributions in excess of tax basis earnings and
profits are reported in the financial statements as a tax return of capital.
Differences in the recognition or classification of income between the
financial statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or accumulated net realized
gains in the components of net assets on the Statement of Assets and
Liabilities.

The tax character of distributions paid during the periods ended December 31,
2003 and 2002 was as follows:

Distributions Paid From:

                                Ordinary Income             Total
                                2003       2002        2003       2002

                              $7,067      $   -      $7,067      $   -

As of December 31, 2003, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:

  Undistributed   Undistributed       Unrealized            Loss
       Ordinary       Long-Term     Appreciation   Carryforwards
         Income            Gain   (Depreciation)   and Deferrals         Total

      $113,929           $6,615         $306,831         $ (718)      $426,657

The difference between book basis and tax basis is attributable primarily to
net operating losses, post October losses, and the tax deferral of losses on
wash sales.

7 Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
tax authorities, net of refunds recoverable.

8 Expense allocation: Certain expenses are applicable to multiple funds.
Expenses directly attributable to a Series are charged to that Series. Expenses
of the Trust that are not directly attributed to a Series are allocated among
the Funds, on the basis of relative net assets, except where a more appropriate
allocation of expenses to each of the Funds can otherwise by made fairly.
Expenses borne by the complex of related investment companies, which includes
open-end and closed-end investment companies for which Management serves as
investment manager, that are not directly attributed to a Series or the Trust,
are allocated among the Fund and the other investment companies in the complex
or series thereof, on the basis of relative net assets, except where a more
appropriate allocation of expenses to each investment company in the complex or
series thereof can otherwise be made fairly.

9 Security lending: Pursuant to an Exemptive Order issued by the Securities and
Exchange Commission, the Fund entered into a Securities Lending Agreement
("Agreement") with Neuberger Berman, LLC ("Neuberger") on April 17, 2003.
Securities loans involve certain risks in the event a borrower should fail
financially, including delays or inability to recover the lent securities or
foreclose against the collateral. The investment manager, under the general
supervision of the Trust's Board of Trustees, monitors the creditworthiness of
the parties to whom the Fund makes security loans. The Fund will not lend
securities on which covered call options have been written, or lend securities
on terms which would prevent the Fund from qualifying as a regulated investment
company. The Fund receives cash collateral equal to at least 102% of the
current market value of the loaned securities. The Fund invests the cash
collateral in the N&B Securities Lending Quality Fund, LLC, which is managed by
State Street Bank and Trust Company ("State Street") pursuant to guidelines
approved by the Trust's investment manager. Neuberger received a portion of the
revenue under the Agreement as a lending agency fee.

The Agreement has been renewed and approved by the Board of Trustees as of July
1, 2004 with substantially the same terms. Under this current Agreement,
Neuberger guarantees minimum revenue to the Fund and receives any revenue
earned in excess of the guaranteed amount as a lending agency fee.

At June 30, 2004, the Fund had not paid Neuberger any fees under the Agreement.

Income earned on the securities loaned, if any, is reflected in the Statement
of Operations under the caption Income from securities loaned-net.

10 Transactions with other funds managed by Neuberger Berman Management Inc.:
Pursuant to an Exemptive Order issued by the Securities and Exchange
Commission, the Fund may invest in the Neuberger Berman Institutional Cash Fund
(the "Cash Fund"), a fund managed by Management and having the same Board
members as the Fund. The Cash Fund seeks to provide as high a level of current
income as is consistent with the preservation of capital and the maintenance of
liquidity. For any cash that the Fund invests in the Cash Fund, Management
waives a portion of its management fee equal to the management fee it receives
from the Cash Fund on those assets. For the six months ended June 30, 2004,
such waived fees amounted to $29. For the six months ended June 30, 2004,
income earned on this investment amounted to $226 and is reflected in the
Statement of Operations under the caption Income from investments in affiliated
issuers.

Note B--Management Fees, Administration Fees, Distribution Arrangements, and
Other Transactions With Affiliates:
Fund shares are issued and redeemed in connection with investments in and
payments under certain variable annuity contracts and variable life insurance
policies issued through separate accounts of life insurance companies and are
also offered directly to qualified pension and retirement plans.

The Fund retains Management as its investment manager under a Management
Agreement. For such investment management services, the Fund pays Management a
fee at the annual rate of 0.55% of the first $250 million of the Fund's average
daily net assets, 0.525% of the next $250 million, 0.50% of the next $250
million, 0.475% of the next $250 million, 0.45% of the next $500 million,
0.425% of the next $2.5 billion, and 0.40% of average daily net assets in
excess of $4 billion.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

The Fund retains Management as its administrator under an Administration
Agreement. The Fund pays Management an administration fee at the annual rate of
0.30% of its average daily net assets under this agreement. Additionally,
Management retains State Street as its sub-administrator under a
Sub-Administration Agreement. Management pays State Street a fee for all
services received under the agreement.

Management acts as agent in arranging for the sale of Fund shares without
commission and bears advertising and promotion expenses. The Trustees of the
Trust have adopted a distribution plan (the "Plan") with respect to the Fund,
pursuant to Rule 12b-1 under the 1940 Act. The Plan provides that, as
compensation for administrative and other services provided to the Fund,
Management's activities and expenses related to the sale and distribution of
the Fund's shares, and ongoing services provided to investors in the Fund,
Management receives from the Fund a fee at the annual rate of 0.25% of its
average daily net assets. Management receives this amount to provide
distribution and shareholder servicing for the Fund and pays a portion of it to
institutions that provide such services. Those institutions may use the
payments for, among other purposes, compensating employees engaged in sales
and/or shareholder servicing. The amount of fees paid by the Fund during any
year may be more or less than the cost of distribution and other services
provided to the Fund. NASD rules limit the amount of annual distribution fees
that may be paid by a mutual fund and impose a ceiling on the cumulative
distribution fees paid. The Trust's Plan complies with those rules.

Management has contractually undertaken through December 31, 2007 to reimburse
the Fund for its operating expenses (including the fees payable to Management
but excluding interest, taxes, brokerage commissions, extraordinary expenses,
and transaction costs) ("Operating Expenses") which exceed, in the aggregate,
1.25% per annum of its average daily net assets (the "Expense Limitation"). For
the six months ended June 30, 2004, such excess expenses amounted to $34,394.
The Fund has agreed to repay Management through December 31, 2010 for its
excess Operating Expenses previously reimbursed by Management, so long as its
annual Operating Expenses during that period do not exceed its Expense
Limitation, and the repayment is made within three years after the year in
which Management issued the reimbursement. During the six months ended June 30,
2004, there was no reimbursement to Management. At June 30, 2004, the Fund has
a contingent liability to Management under this agreement of $149,786.

On October 31, 2003, Management and Neuberger, a member firm of the New York
Stock Exchange and sub-adviser to the Fund, became indirect wholly-owned
subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned
holding company. Neuberger is retained by Management to furnish it with
investment recommendations and research information without added cost to the
Fund. Several individuals who are officers and/or Trustees of the Trust are
also employees of Neuberger and/or Management.

On July 1, 2003, the Fund entered into a commission recapture program, which
enables it to pay some of its operational expenses by recouping a portion of
the commissions it pays to a broker that is not a related party of the Fund.
Expenses paid through this program may include costs of custodial, transfer
agency or accounting services. For the six months ended June 30, 2004, the
impact of this arrangement was a reduction of $35.


                                       11





Notes to Financial Statements Focus Portfolio cont'd

The Fund has an expense offset arrangement in connection with its custodian
contract. The impact of this arrangement, reflected in the Statement of
Operations under the caption Custodian fees, was a reduction of $0.

Note C--Securities Transactions:

During the six months ended June 30, 2004, there were purchase and sale
transactions (excluding short-term securities) of $197,762 and $150,495,
respectively.

During the six months ended June 30, 2004, brokerage commissions on securities
transactions amounted to $650, of which Neuberger received $0, Lehman received
$75, and other brokers received $575.

Note E--Line of Credit:

At June 30, 2004, the Fund was a participant in a single committed, unsecured
$150,000,000 line of credit with State Street, to be used only for temporary or
emergency purposes. Interest is charged on borrowings under this agreement at
the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.10%
per annum of the available line of credit is charged, of which the Fund has
agreed to pay its pro rata share, based on the ratio of its individual net
assets to the net assets of all participants at the time the fee is due and
payable. The fee is paid quarterly in arrears. No compensating balance is
required. Other investment companies managed by Management also participate in
this line of credit on the same terms. Because several investment companies
participate, there is no assurance that the Fund will have access to the entire
$150,000,000 at any particular time. The Fund had no loans outstanding pursuant
to this line of credit at June 30, 2004, nor had the Fund utilized this line of
credit at any time prior to that date.

Note F--Unaudited Financial Information:

The financial information included in this interim report is taken from the
records of the Fund without audit by independent auditors. Annual reports
contain audited financial statements.

Growth Portfolio Managers' Commentary

The AMT Growth Portfolio ended the first half of 2004 with a gain of 7.49%,
outperforming the Russell Midcap Growth Index return of 5.94%.2 This
outperformance reflected the fact that the market began rewarding stocks with
solid business fundamentals as opposed to unproven growth prospects, a trend
that favored our investment process. Our stock selection boosted our performance
across most sectors of the portfolio.

The largest contribution to relative performance came from stock selection in
the information technology, consumer discretionary and financial sectors. Stocks
that did well in IT included companies that develop and provide specialized
technologies to businesses such as Zebra Technologies. Within consumer
discretionary, our emphasis in entertainment and leisure and specialty retail
companies were some of the primary reasons for this outperformance with Royal
Caribbean Cruises and PETsMART both performing well. Within the financials
sector, Capital One Financial, First Marblehead, and Investors Financial
Services were all strong performers, as they represent less interest rate
sensitive names within that sector.

In the aggregate, our sector allocation was slightly negative on a year-to-date
basis, with our underweight position in both consumer staples and healthcare
accounting for much of the underperformance.

After beginning the year with strong advances, the market began trading sideways
during the second quarter. In the aggregate, for the first half of 2004, the
markets have confounded consensus expectations by trading in very narrow ranges
with only a 7% swing on the Standard & Poor's 500 Index. As we anticipated early
in the year, the equity markets have experienced substantial rotation between
cyclical (materials/technology) and defensive (healthcare/staples)
industries/sectors as investors reacted to the shifting economic news.

Economic forecasting is exceptionally difficult this year as we formulate the
top-down part of our strategy. In addition to the initiation of a tightening
cycle by the Fed, we face the expiration of some tax cuts this year, a slowing
Chinese economy, U.S. political uncertainty and volatile oil prices. Like a pig
in a python, the lower dollar, faster than expected U.S. growth and the strong
Asian demand for commodities last year are working their way through the system
and causing rates of inflation to accelerate this year. We believe that many of
these influences have dissipated, however, so the Fed may not need to react as
strongly as investors fear.

As investors grapple with higher inflation and the expected continuing interest
rate hikes by the Fed, worries are also growing that the economy is slowing.
Recently, Wal-Mart, Target and General Motors lowered their top-line forecasts.
Similar to our view on inflation, we are also relatively sanguine about economic
growth. It is important to note that while overall growth is fine, the
composition of economic activity is changing from a mortgage refinanced/lower
tax consumer-led recovery to one being sustained by corporate investment,
inventory building and steady job creation.

Even though we are not pessimistic in terms of the overall economy and
inflation, we are not optimistic in terms of near-term stock performance. We
expect equities to struggle as profit growth slows, interest rates increase, and
the Presidential election remains tight. Over the past six years, the S&P 500 is
essentially flat in price while earnings have increased by a third. The market's
forward P/E has collapsed from 21 to 16 during this period. However, the stock
market is still not cheap, since a P/E of 16 is the long-term average. We
believe P/Es will continue to wilt in the heat of the summer months.
Uncertainties about next year's economy will most likely increase as more
difficult earnings comparisons will begin this


                                        1





quarter. If fears become more intense and investors overreact, we expect poor
near-term equity performance to provide a platform for better equity performance
in the latter part of this year.

We have reduced our position in the materials sector to an underweight relative
to the benchmark on the basis of our concerns that global growth rates have
peaked. Industrials and energy remain moderately overweighted, financials
moderately underweighted, utilities underweighted, and other sectors relatively
neutral weighted.

We seek to continue to position the portfolio with tilts toward lower volatility
stocks in higher quality companies with lower earnings variability. As interest
rates move higher and growth rates slow, we believe that companies with
financial strength should be favored.

Sincerely,


                               /s/ Jon D. Brorson

1. 23.48%, (2.68%) and 7.36% were the average annual total returns for the 1-,
5- and 10-year periods ended June 30, 2004. Neuberger Berman Management Inc.
("NBMI") has agreed to absorb certain expenses of the AMT Portfolios. Without
this arrangement, which is subject to change, the total returns of the
Portfolios would be less. Total return includes reinvestment of dividends and
capital gain distributions. Performance data quoted represent past performance
and the investment return and principal value of an investment will fluctuate so
that the shares, when redeemed, may be worth more or less than original cost.
Current performance may be lower or higher than the performance data quoted. For
performance data current to the most recent month end, please visit
www.nb.com/amtperformance. The performance information does not reflect fees and
expenses of the variable annuity and variable life insurance policies or the
pension plans whose proceeds are invested in the portfolio.

2. The Russell Midcap(Reg) Growth Index measures the performance of those
Russell Midcap(Reg) Index companies with higher price-to-book ratios and higher
forecasted growth values. The Russell Midcap Index measures the performance of
the 800 smallest companies in the Russell 1000(Reg) Index, which represents
approximately 27% of the total market capitalization of the Russell 1000 Index
(which, in turn, consists of the 1,000 largest U.S. companies, based on market
capitalization). The S&P 500 Index is widely regarded as the standard for
measuring large-cap U.S. stock market performance and includes a representative
sample of leading companies in leading industries. Please note that indices do
not take into account any fees and expenses of investing in the individual
securities that they track, and that individuals cannot invest directly in any
index. Data about the performance of these indices are prepared or obtained by
NBMI and include reinvestment of all dividends and capital gain distributions.
The Portfolio may invest in many securities not included in the above-described
indices.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)


Notes to Schedule of Investments Growth Portfolio

+    Investments in equity securities by the Fund are valued at the latest sales
     price where that price is readily available; securities for which no sales
     were reported, unless otherwise noted, are valued at the mean between the
     closing bid and asked prices. Securities traded primarily on the NASDAQ
     Stock Market are normally valued by the Fund at the NASDAQ Official Closing
     Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most
     recently reported price as of 4:00:02 p.m., Eastern time, unless that price
     is outside the range of the "inside" bid and asked prices (i.e., the bid
     and asked prices that dealers quote to each other when trading for their
     own accounts); in that case, NASDAQ will adjust the price to equal the
     inside bid or asked price, whichever is closer. Because of delays in
     reporting trades, the NOCP may not be based on the price of the last trade
     to occur before the market closes. The Fund values all other securities by
     a method the Board of Trustees of Neuberger Berman Advisers Management
     Trust (the "Board") believes accurately reflects fair value. Numerous
     factors may be considered when determining the fair value of a security,
     including available analyst, media or other reports, trading in futures or
     ADRs and whether the issuer of the security being fair valued has other
     securities outstanding. Foreign security prices are furnished by
     independent quotation services expressed in local currency values. Foreign
     security prices are translated from the local currency into U.S. dollars
     using the exchange rate as of 12:00 p.m., Eastern time. The Board has
     approved the use of FT Interactive Data Corporation ("FT Interactive") to
     assist in determining the fair value of the Fund's foreign equity
     securities in the wake of certain significant events. Specifically, when
     changes in the value of a certain index suggest that the closing prices on
     the foreign exchanges no longer represent the amount that the Fund could
     expect to receive for those securities, FT Interactive will provide
     adjusted prices for certain foreign equity securities based on an analysis
     showing historical correlations between the prices of those securities and
     changes in the index. In the absence of precise information about the
     market values of these foreign securities as of the close of the New York
     Stock Exchange, the Board has determined on the basis of available data
     that prices adjusted in this way are likely to be closer to the prices the
     Fund could realize on a current sale than are the prices of those
     securities established at the close of the foreign markets in which the
     securities primarily trade. However, fair value prices are necessarily
     estimates, and there is no assurance that such a price will be at or close
     to the price at which the security next trades. Short-term debt securities
     with less than 60 days until maturity may be valued at cost which, when
     combined with interest earned, approximates market value.

#    At cost, which approximates market value.

##   At June 30, 2004, the cost of investments for U.S. Federal income tax
     purposes was $217,401,941. Gross unrealized appreciation of investments was
     $52,160,261 and gross unrealized depreciation of investments was
     $2,349,675, resulting in net unrealized appreciation of $49,810,586, based
     on cost for U.S. Federal income tax purposes.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)


Notes to Financial Statements Growth Portfolio

Note A--Summary of Significant Accounting Policies:

1 General: Growth Portfolio (the "Fund") is a separate operating series of
Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware statutory
trust organized pursuant to a Trust Instrument dated May 23, 1994. The Trust is
currently comprised of ten separate operating series (each a "Series,"
collectively, the "Funds") each of which (except Focus Portfolio) is
diversified. The Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act"),
and its shares are registered under the Securities Act of 1933, as amended. The
Fund currently offers only Class I shares. The Board of Trustees of the Trust
may establish additional series or classes of shares without the approval of
shareholders.

The assets of each Series belong only to that Series, and the liabilities of
each Series are borne solely by that Series and no other.

The preparation of financial statements in accordance with accounting principles
generally accepted in the United States requires Neuberger Berman Management
Inc. ("Management") to make estimates and assumptions at the date of the
financial statements. Actual results could differ from those estimates.

2 Portfolio valuation: Investment securities are valued as indicated in the
notes following the Schedule of Investments.

3 Foreign currency translation: The accounting records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars using the exchange rate as of 12:00 p.m., Eastern time, to determine the
value of investments, other assets and liabilities. Purchase and sale prices of
securities, and income and expenses, are translated into U.S. dollars at the
prevailing rate of exchange on the respective dates of such transactions. Net
unrealized foreign currency gain (loss) arises from changes in the value of
assets and liabilities, other than investments in securities, as a result of
changes in exchange rates and is stated separately in the Statement of
Operations.

4 Securities transactions and investment income: Securities transactions are
recorded on a trade date basis. Dividend income is recorded on the ex-dividend
date or, for certain foreign dividends, as soon as the Fund becomes aware of the
dividends. Non-cash dividends included in dividend income, if any, are recorded
at the fair market value of the securities received. Interest income, including
accretion of original issue discount, where applicable, and accretion of
discount on short-term investments, is recorded on the accrual basis. Realized
gains and losses from securities transactions and foreign currency transactions
are recorded on the basis of identified cost and stated separately in the
Statement of Operations. Included in net realized gain (loss) on investment
securities sold are proceeds from the settlements of class action litigation in
which the Fund participated as a plaintiff. The amount of such proceeds for the
six months ended June 30, 2004 was $56,650.

5 Federal income taxes: The Funds are treated as separate entities for U.S.
Federal income tax purposes. It is the policy of the Fund to continue to qualify
as a regulated investment company by complying with the provisions available to
certain investment companies, as defined in applicable sections of the Internal


                                        12





Notes to Financial Statements Growth Portfolio cont'd

Revenue Code, and to make distributions of investment company taxable income and
net capital gains (after reduction for any amounts available for U.S. Federal
income tax purposes as capital loss carryforwards) sufficient to relieve it from
all, or substantially all, U.S. Federal income taxes. Accordingly, the Fund paid
no U.S. Federal income taxes and no provision for U.S. Federal income taxes was
required.

6 Dividends and distributions to shareholders: The Fund may earn income, net of
expenses, daily on its investments. Income dividends and distributions from net
realized capital gains, if any, generally are distributed in October. Income
dividends and capital gain distributions to shareholders are recorded on the
ex-dividend date. To the extent the Fund's net realized capital gains, if any,
can be offset by capital loss carryforwards ($228,884,941 and $70,119,797
expiring in 2009 and 2010, respectively, determined as of December 31, 2003), it
is the policy of the Fund not to distribute such gains.

The Fund distinguishes between dividends on a tax basis and a financial
reporting basis and only distributions in excess of tax basis earnings and
profits are reported in the financial statements as a tax return of capital.
Differences in the recognition or classification of income between the financial
statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or accumulated net realized
gains in the components of net assets on the Statement of Assets and
Liabilities.

As of December 31, 2003, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:


                       Unrealized                   Loss
                     Appreciation          Carryforwards
                   (Depreciation)          and Deferrals                   Total

                      $44,295,706         $(299,004,738)          $(254,709,032)


The difference between book basis and tax basis is attributable primarily to net
operating losses and the tax deferral of losses on wash sales.

7 Expense allocation: Certain expenses are applicable to multiple funds.
Expenses directly attributable to a Series are charged to that Series. Expenses
of the Trust that are not directly attributed to a Series are allocated among
the Funds, on the basis of relative net assets, except where a more appropriate
allocation of expenses to each of the Funds can otherwise be made fairly.
Expenses borne by the complex of related investment companies, which includes
open-end and closed-end investment companies for which Management serves as
investment manager, that are not directly attributed to a Series or the Trust,
are allocated among the Fund and the other investment companies in the complex
or series thereof, on the basis of relative net assets, except where a more
appropriate allocation of expenses to each investment company in the complex or
series thereof can otherwise be made fairly.

8 Security lending: Pursuant to an Exemptive Order issued by the Securities and
Exchange Commission, the Fund entered into a Securities Lending Agreement
("Agreement") with Neuberger Berman, LLC ("Neuberger") on April 17, 2003.
Securities loans involve certain risks in the event a borrower should fail
financially, including delays or inability to recover the lent securities or
foreclose against the collateral. The investment manager, under the general
supervision of the Trust's Board of Trustees, monitors the creditworthiness of
the parties to whom the Fund makes security loans. The Fund will not lend
securities

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

on which covered call options have been written, or lend securities on terms
which would prevent the Fund from qualifying as a regulated investment company.
The Fund receives cash collateral equal to at least 102% of the current market
value of the loaned securities. The Fund invests the cash collateral in the N&B
Securities Lending Quality Fund, LLC, which is managed by State Street Bank and
Trust Company ("State Street") pursuant to guidelines approved by the Trust's
investment manager. Neuberger guaranteed minimum revenue to the Fund under the
Agreement, and received a portion of any revenue earned in excess of the
guaranteed amount as a lending agency fee.

The Agreement has been renewed and approved by the Board of Trustees as of July
1, 2004 with substantially the same terms. Under this current Agreement,
Neuberger guarantees minimum revenue to the Fund and receives any revenue earned
in excess of the guaranteed amount as a lending agency fee.

At June 30, 2004, the Fund had not paid Neuberger any fees under the Agreement.

Income earned on the securities loaned, if any, is reflected in the Statement of
Operations under the caption Income from securities loaned-net.

9 Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
tax authorities, net of refunds recoverable.

10 Repurchase agreements: The Fund may enter into repurchase agreements with
institutions that the Fund's investment manager has determined are creditworthy.
Each repurchase agreement is recorded at cost. The Fund requires that the
securities purchased in a repurchase agreement be transferred to the custodian
in a manner sufficient to enable the Fund to assert a perfected security
interest in those securities in the event of a default under the repurchase
agreement. The Fund monitors, on a daily basis, the value of the securities
transferred to ensure that their value, including accrued interest, is greater
than amounts owed to the Fund under each such repurchase agreement.

11 Transactions with other funds managed by Neuberger Berman Management Inc.:
Pursuant to an Exemptive Order issued by the Securities and Exchange Commission,
the Fund may invest in the Neuberger Berman Institutional Cash Fund (the "Cash
Fund"), a fund managed by Management and having the same Board members as the
Fund. The Cash Fund seeks to provide as high a level of current income as is
consistent with the preservation of capital and the maintenance of liquidity.
For any cash that the Fund invests in the Cash Fund, Management waives a portion
of its management fee equal to the management fee it receives from the Cash Fund
on those assets. For the six months ended June 30, 2004, such waived fees
amounted to $283. For the six months ended June 30, 2004, income earned on this
investment amounted to $2,074 and is reflected in the Statement of Operations
under the caption Income from investments in affiliated issuers.

Note B--Management Fees, Administration Fees, Distribution Arrangements, and
Other Transactions With Affiliates:

Fund shares are issued and redeemed in connection with investments in and
payments under certain variable annuity contracts and variable life insurance
policies issued through separate accounts of life insurance companies and are
also offered directly to qualified pension and retirement plans.

The Fund retains Management as its investment manager under a Management
Agreement. For such investment management services, the Fund pays Management a
fee at the annual rate of 0.55% of the first $250 million of the Fund's average
daily net assets, 0.525% of the next $250 million, 0.50% of the next $250
million, 0.475% of the next $250 million, 0.45% of the next $500 million, 0.425%
of the next $2.5 billion, and 0.40% of average daily net assets in excess of $4
billion.

The Fund retains Management as its administrator under an Administration
Agreement. The Fund pays Management an administration fee at the annual rate of
0.30% of its average daily net assets under this agreement. Additionally,
Management retains State Street as its sub-administrator under a Sub-
Administration Agreement. Management pays State Street a fee for all services
received under the agreement.

The Trustees of the Trust adopted a non-fee distribution plan for the Fund.

Management has contractually undertaken through December 31, 2007 to reimburse
the Fund for its operating expenses (excluding the fees payable to Management,
interest, taxes, brokerage commissions, extraordinary expenses, and transaction
costs) ("Operating Expenses") which exceed, in the aggregate, 1.00% per annum of
its average daily net assets (the "Expense Limitation"). For the six months
ended June 30, 2004, no reimbursement to the Fund was required. The Fund has
agreed to repay Management through December 31, 2010 for its excess Operating
Expenses previously reimbursed by Management, so long as its annual Operating
Expenses during that period do not exceed its Expense Limitation, and the
repayment is made within three years after the year in which Management issued
the reimbursement. During the six months ended June 30, 2004, there was no
reimbursement to Management. At June 30, 2004, the Fund has no contingent
liability to Management under the agreement.

On October 31, 2003, Management and Neuberger, a member firm of the New York
Stock Exchange and sub-adviser to the Fund, became indirect wholly-owned
subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned
holding company. Neuberger is retained by Management to furnish it with
investment recommendations and research information without added cost to the
Fund. Several individuals who are officers and/or Trustees of the Trust are also
employees of Neuberger and/or Management.

On July 1, 2003, the Fund entered into a commission recapture program, which
enables it to pay some of its operational expenses by recouping a portion of the
commissions it pays to a broker that is not a related party of the Fund.
Expenses paid through this program may include costs of custodial, transfer
agency or accounting services. For the six months ended June 30, 2004, the
impact of this arrangement was a reduction of $24,838.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

The Fund has an expense offset arrangement in connection with its custodian
contract. The impact of this arrangement, reflected in the Statement of

transactions (excluding short-term securities) of $94,558,938 and $114,311,340,
respectively.

During the six months ended June 30, 2004, brokerage commissions on securities
transactions amounted to $302,312, of which Neuberger received $0, Lehman

Note E--Line of Credit:

At June 30, 2004, the Fund was a participant in a single committed, unsecured
$150,000,000 line of credit with State Street, to be used only for temporary or
emergency purposes. Interest is charged on borrowings under this agreement at
the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.10%
per annum of the available line of credit is charged, of which the Fund has
agreed to pay its pro rata share, based on the ratio of its individual net
assets to the net assets of all participants at the time the fee is due and
payable. The fee is paid quarterly in arrears. No compensating balance is
required. Other investment companies managed by Management also participate in
this line of credit on the same terms. Because several investment companies
participate, there is no assurance that the Fund will have access to the entire
$150,000,000 at any particular time. The Fund had no loans outstanding pursuant
to this line of credit at June 30, 2004.

Note F--Unaudited Financial Information:

The financial information included in this interim report is taken from the
records of the Fund without audit by independent auditors. Annual reports
contain audited financial statements.

Notes to Financial Highlights Growth Portfolio

+     The per share amounts and ratios which are shown reflect income and
      expenses, including the Fund's proportionate share of AMT Growth
      Investment's income and expenses through April 30, 2000 under the prior
      master/feeder fund structure.

++    Total return based on per share net asset value reflects the effects of
      changes in net asset value on the performance of the Fund during each
      fiscal period and assumes dividends and other distributions, if any, were
      reinvested. Results represent past performance and do not guarantee future
      results. Current returns may be lower or higher than the performance data
      quoted. Investment returns and principal may fluctuate and shares when
      redeemed may be worth more or less than original cost. Total return would
      have been lower if Management had not waived certain expenses. The total
      return information shown does not reflect charges and other expenses that
      apply to the separate account or the related insurance policies, and the
      inclusion of these charges and other expenses would reduce the total
      return for all fiscal periods shown. Performance data current to the most
      recent month-end are available at www.nb.com.

#     The Fund is required to calculate an expense ratio without taking into
      consideration any expense reductions related to expense offset and
      commission recapture arrangements.

++    The per share amounts which are shown have been computed based on the
      average number of shares outstanding during each fiscal period.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

Guardian Portfolio Manager's Commentary

While returns were relatively modest in the first half of 2004, we are pleased
to report that the Guardian Portfolio outperformed both its Standard & Poor's
500 Index and Russell 1000 Value Index benchmarks during the period.2

Concerned by the shift in Federal Reserve policy, high oil prices, geopolitical
tensions, and the threat of terrorism, investors largely ignored consistently
positive economic news and strong corporate profit growth in the first half of
2004. Although the stock market as a whole has remained in a trading range,
there was considerable volatility within and across market sectors, creating an
even greater challenge for investors.

Energy sector investments had the most favorable impact on portfolio returns. We
were overweighted in energy and our holdings significantly outperformed the
benchmark energy sector components. Newfield Exploration, EOG Resources, and
Schlumberger appeared on our top ten performance list. Our initial attraction to
energy stocks was based on the fact that although global demand was rising,
there was very little capital being devoted to increasing production. The
ensuing supply/demand imbalance resulted in higher energy prices, improved
profits for energy companies, and strong performance from our energy holdings.
Despite good gains in the first half, we believe our energy investments continue
to represent good value. Although OPEC appears to be making a sincere effort to
bring energy prices down, strikes in the Norwegian and Nigerian oil fields and
sabotage in Iraq have restrained supply while global inventories remain low.
Since energy demand generally strengthens in the latter half of the year, we
believe that the window of opportunity to increase energy inventories to a level
that would help significantly reduce prices may have closed.

Industrial sector investments also contributed to relative performance. We were
overweighted in industrials versus the benchmarks and our holdings outperformed
by a wide margin. Defense electronics company L-3 Communications was the
portfolio's top performer. L-3 is a leading supplier of defense electronics and
battlefield communications systems. Although still a relatively small part of
its business, L-3 has developed several technologies with potential homeland
security applications, including ship-to-Coast Guard signaling devices and
sensor-based detectors for checking the contents of shipping containers. The
company is also one of two licensed vendors for baggage screening equipment for
U.S. airports. Going forward, we think these homeland security oriented products
will become bigger contributors to L-3's earnings and enhance future growth.

Our consumer discretionary sector investments retreated. Comcast, the nation's
largest cable television operator, was among the disappointments as its shares
were buffeted by multiple investor concerns. Initially, investors were
disappointed by Comcast's unsolicited bid for Disney. Then investors worried
when the Regional Bell Operating Companies (RBOCs) began discussing new fiber
strategies that could facilitate competing broadband video services. Finally,
there was some general concern that corporate advertising spending was not
recovering as quickly as anticipated. For the time being, it appears that
Comcast has given up on Disney and is unlikely to make a run at another
"content" company. While the RBOCs appear committed to getting into the video
business, it's going to cost a lot of money and take considerable time to
improve their broadband infrastructure before they can become serious
competitors to the established cable television operators like Comcast. In fact,
we suspect that over the next few years, the cable companies will have more
success capturing telephony business from the telephone companies than the
telcos will have winning over cable TV customers. While in general, advertising
spending has disappointed, cable television companies are


                                       1





getting a bigger piece of the pie. This is a direct result of giant Comcast's
(20 million homes served) interconnection agreements with other large cable
operators. In the past, cable operators sold low cost, low margin ads to local
businesses. Now, they can approach national advertisers with more compelling
demographics. This should improve Comcast's and other CATV operators'
advertising profits.

The economy appears to be making the transition from recovery to a slower growth
expansion phase. Anxious investors have been focusing on the potential negatives
rather than the positives. However, six months from now, if there are no
external events that derail the economy, we believe investor sentiment will
improve and companies that execute their business plans and deliver solid
earnings growth will be rewarded in the stock market. Recall that our investment
process is based on our own intensive fundamental research. We are
valuation-sensitive, long-term investors who evaluate the business potential for
portfolio candidates based on our targeted three-to-five year holding period.
Within industry sectors, we seek out the companies that we believe are best
positioned to deliver industry leading business performance. Furthermore, we are
strongly biased toward companies in industry sectors benefiting from favorable
secular trends. We believe that these are the kind of stocks that can
distinguish themselves in the year ahead.

Sincerely,

1. For Class I, 20.44%, (0.28%) and 7.32% were the average annual total returns
for the 1-year, 5- year and since inception (11/03/97) periods ended June 30,
2004. For Class S, 20.19%, (0.37%) and 7.25% were the average annual total
returns for the 1-year, 5-year and since inception (11/03/97) periods ended June
30, 2004. Performance shown prior to August 2002 for the Class S shares is of
the Class I shares, which has lower expenses and typically higher returns than
Class S shares. Neuberger Berman Management Inc. ("NBMI") has agreed to absorb
certain expenses of the AMT Portfolios. Without this arrangement, which is
subject to change, the total returns of the Portfolios would be less. Total
return includes reinvestment of dividends and capital gain distributions.
Performance data quoted represent past performance and the investment return and
principal value of an investment will fluctuate so that the shares, when
redeemed, may be worth more or less than original cost. Current performance may
be lower or higher than the performance data quoted. For performance data
current to the most recent month end, please visit www.nb.com/amtperformance.
The performance information does not reflect fees and expenses of the variable
annuity and variable life insurance policies or the pension plans whose proceeds
are invested in the portfolio.

2. The S&P 500 Index is widely regarded as the standard for measuring large-cap
U.S. stock market performance and includes a representative sample of leading
companies in leading industries. The Russell 1000[RegTM]Index measures the
performance of the 1,000 largest companies in the Russell 3000[RegTM] Index
(which measures the performance of the 3,000 largest U.S. companies based on
total market capitalization). The Russell 1000 Index represents approximately
92% of the total market capitalization of the Russell 3000 Index. The Russell
1000 Value Index measures the performance of those Russell 1000 companies with
lower price-to-book ratios and lower forecasted growth values. Please note that
indices do not take into account any fees and expenses of investing in the
individual securities that they track, and that individuals cannot invest
directly in any index. Data about the performance of these indices are prepared
or obtained by NBMI and include reinvestment of all dividends and capital gain
distributions. The Portfolio may invest in many securities not included in the
above-described indices.

The composition, industries and holdings of the Portfolio are subject to change.

+    Investments in equity securities by the Fund are valued at the latest sales
     price where that price is readily available; securities for which no sales
     were reported, unless otherwise noted, are valued at the mean between the
     closing bid and asked prices. Securities traded primarily on the NASDAQ
     Stock Market are normally valued by the Fund at the NASDAQ Official Closing
     Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most
     recently reported price as of 4:00:02 p.m., Eastern time, unless that price
     is outside the range of the "inside" bid and asked prices (i.e., the bid
     and asked prices that dealers quote to each other when trading for their
     own accounts); in that case, NASDAQ will adjust the price to equal the
     inside bid or asked price, whichever is closer. Because of delays in
     reporting trades, the NOCP may not be based on the price of the last trade
     to occur before the market closes. The Fund values all other securities by
     a method the Board of Trustees of Neuberger Berman Advisers Management
     Trust (the "Board") believes accurately reflects fair value. Numerous
     factors may be considered when determining the fair value of a security,
     including available analyst, media or other reports, trading in futures or
     ADRs and whether the issuer of the security being fair valued has other
     securities outstanding. Foreign security prices are furnished by
     independent quotation services expressed in local currency values. Foreign
     security prices are translated from the local currency into U.S. dollars
     using the exchange rate as of 12:00 p.m., Eastern time. The Board has
     approved the use of FT Interactive Data Corporation ("FT Interactive") to
     assist in determining the fair value of the Fund's foreign equity
     securities in the wake of certain significant events. Specifically, when
     changes in the value of a certain index suggest that the closing prices on
     the foreign exchanges no longer represent the amount that the Fund could
     expect to receive for those securities, FT Interactive will provide
     adjusted prices for certain foreign equity securities based on an analysis
     showing historical correlations between the prices of those securities and
     changes in the index. In the absence of precise information about the
     market values of these foreign securities as of the close of the New York
     Stock Exchange, the Board has determined on the basis of available data
     that prices adjusted in this way are likely to be closer to the prices the
     Fund could realize on a current sale than are the prices of those
     securities established at the close of the foreign markets in which the
     securities primarily trade. However, fair value prices are necessarily
     estimates, and there is no assurance that such a price will be at or close
     to the price at which the security next trades. Short-term debt securities
     with less than 60 days until maturity may be valued at cost which, when
     combined with interest earned, approximates market value.

#    At cost, which approximates market value.

##   At June 30, 2004, the cost of investments for U.S. Federal income tax
     purposes was $155,321,109. Gross unrealized appreciation of investments was
     $37,744,962 and gross unrealized depreciation of investments was $726,561,
     resulting in net unrealized appreciation of $37,018,401, based on cost for
     U.S. Federal income tax purposes.

Notes to Financial Statements Guardian Portfolio
- ------------------------------------------------

     Note A--Summary of Significant Accounting Policies:

1    General: Guardian Portfolio (the "Fund") is a separate operating series of
     Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware
     statutory trust organized pursuant to a Trust Instrument dated May 23,
     1994. The Trust is currently comprised of ten separate operating series
     (each a "Series," collectively, the "Funds") each of which (except Focus
     Portfolio) is diversified. The Trust is registered as an open-end
     management investment company under the Investment Company Act of 1940, as
     amended (the "1940 Act"), and its shares are registered under the
     Securities Act of 1933, as amended. The Fund currently offers Class I and
     Class S shares. The Board of Trustees of the Trust may establish additional
     series or classes of shares without the approval of shareholders.

     The assets of each Series belong only to that Series, and the liabilities
     of each Series are borne solely by that Series and no other.

     The preparation of financial statements in accordance with accounting
     principles generally accepted in the United States requires Neuberger
     Berman Management Inc. ("Management") to make estimates and assumptions at
     the date of the financial statements. Actual results could differ from
     those estimates.

2    Portfolio valuation: Investment securities are valued as indicated in the
     notes following the Schedule of Investments.

3    Foreign currency translation: The accounting records of the Fund are
     maintained in U.S. dollars. Foreign currency amounts are translated into
     U.S. dollars using the exchange rate as of 12:00 p.m., Eastern time, to
     determine the value of investments, other assets and liabilities. Purchase
     and sale prices of securities, and income and expenses, are translated into
     U.S. dollars at the prevailing rate of exchange on the respective dates of
     such transactions. Net unrealized foreign currency gain (loss) arises from
     changes in the value of assets and liabilities, other than investments in
     securities, as a result of changes in exchange rates and is stated
     separately in the Statement of Operations.

4    Securities transactions and investment income: Securities transactions are
     recorded on a trade date basis. Dividend income is recorded on the
     ex-dividend date or, for certain foreign dividends, as soon as the Fund
     becomes aware of the dividends. Non-cash dividends included in dividend
     income, if any, are recorded at the fair market value of the securities
     received. Interest income, including accretion of original issue discount,
     where applicable, and accretion of discount on short-term investments, is
     recorded on the accrual basis. Realized gains and losses from securities
     transactions and foreign currency transactions are recorded on the basis of
     identified cost and stated separately in the Statement of Operations.
     Included in net realized gain (loss) on investment securities sold are
     proceeds from the settlements of class action litigation in which the Fund
     participated as a plaintiff. The amount of such proceeds for the six months
     ended June 30, 2004 was $98,457.

5    Federal income taxes: The Funds are treated as separate entities for U.S.
     Federal income tax purposes. It is the policy of the Fund to continue to
     qualify as a regulated investment company by complying with the provisions
     available to certain investment companies, as defined in applicable
     sections of the Internal


                                       10





            NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     Revenue Code, and to make distributions of investment company taxable
     income and net capital gains (after reduction for any amounts available for
     U.S. Federal income tax purposes as capital loss carryforwards) sufficient
     to relieve it from all, or substantially all, U.S. Federal income taxes.
     Accordingly, the Fund paid no U.S. Federal income taxes and no provision
     for U.S. Federal income taxes was required.

6    Dividends and distributions to shareholders: The Fund may earn income, net
     of expenses, daily on its investments. Income dividends and distributions
     from net realized capital gains, if any, generally are distributed in
     October. Income dividends and capital gain distributions to shareholders
     are recorded on the ex-dividend date. To the extent the Fund's net realized
     capital gains, if any, can be offset by capital loss carryforwards
     ($11,716,397, $39,047,105 and $5,695,372 expiring in 2009, 2010 and 2011,
     respectively, determined as of December 31, 2003), it is the policy of the
     Fund not to distribute such gains.

     The Fund distinguishes between dividends on a tax basis and a financial
     reporting basis and only distributions in excess of tax basis earnings and
     profits are reported in the financial statements as a tax return of
     capital. Differences in the recognition or classification of income between
     the financial statements and tax earnings and profits which result in
     temporary over-distributions for financial statement purposes are
     classified as distributions in excess of net investment income or
     accumulated net realized gains in the components of net assets on the
     Statement of Assets and Liabilities.

     The tax character of distributions paid during the years ended December 31,
     2003 and 2002 was as follows:

     Distributions Paid From:
              Ordinary Income                      Total
              2003            2002            2003            2002

        $1,313,998      $1,258,878      $1,313,998      $1,258,878

     As of December 31, 2003, the components of distributable earnings
     (accumulated losses) on a U.S. Federal income tax basis were as follows:

     Undistributed         Unrealized              Loss
          Ordinary       Appreciation     Carryforwards
            Income     (Depreciation)     and Deferrals           Total

          $376,027        $35,914,577      $(56,458,874)   $(20,168,270)

     The difference between book basis and tax basis is attributable primarily
     to the tax deferral of losses on wash sales, and the realization for tax
     purposes of unrealized gain (loss) on certain forward foreign currency
     contracts.

7    Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
     tax authorities, net of refunds recoverable.

8    Expense allocation: Certain expenses are applicable to multiple funds.
     Expenses directly attributable to a Series are charged to that Series.
     Expenses of the Trust that are not directly attributed to a Series are
     allocated among the Funds, on the basis of relative net assets, except
     where a more appropriate allocation of expenses to each of the Funds can
     otherwise be made fairly. Expenses borne by the complex of related
     investment companies, which includes open-end and closed-end investment
     companies for which Management serves as investment manager, that are not
     directly attributed to a Series or the Trust are allocated among the Fund
     and the other investment companies in the complex or series thereof, on the


                                       11





Notes to Financial Statements Guardian Portfolio cont'd
- -------------------------------------------------------

     basis of relative net assets, except where a more appropriate allocation of
     expenses to each investment company in the complex or series thereof can
     otherwise be made fairly. The Fund's expenses (other than those specific to
     each class) are allocated proportionally each day between the classes based
     upon the relative net assets of each class.

9    Security lending: Pursuant to an Exemptive Order issued by the Securities
     and Exchange Commission, the Fund entered into a Securities Lending
     Agreement ("Agreement") with Neuberger Berman, LLC ("Neuberger") on April
     17, 2003. Securities loans involve certain risks in the event a borrower
     should fail financially, including delays or inability to recover the lent
     securities or foreclose against the collateral. The investment manager,
     under the general supervision of the Trust's Board of Trustees, monitors
     the creditworthiness of the parties to whom the Fund makes security loans.
     The Fund will not lend securities on which covered call options have been
     written, or lend securities on terms which would prevent the Fund from
     qualifying as a regulated investment company. The Fund receives cash
     collateral equal to at least 102% of the current market value of the loaned
     securities. The Fund invests the cash collateral in the N&B Securities
     Lending Quality Fund, LLC, which is managed by State Street Bank and Trust
     Company ("State Street") pursuant to guidelines approved by the Trust's
     investment manager. Neuberger guaranteed minimum revenue to the Fund under
     the Agreement, and received a portion of any revenue earned in excess of
     the guaranteed amount as a lending agency fee.

     The Agreement has been renewed and approved by the Board of Trustees as of
     July 1, 2004 with substantially the same terms. Under this current
     Agreement, Neuberger guarantees minimum revenue to the Fund and receives
     any revenue earned in excess of the guaranteed amount as a lending agency
     fee.

     At June 30, 2004, the Fund had not paid Neuberger any fees under the
     Agreement.

     Income earned on the securities loaned, if any, is reflected in the
     Statement of Operations under the caption Income from securities
     loaned-net.

10   Repurchase agreements: The Fund may enter into repurchase agreements with
     institutions that the Fund's investment manager has determined are
     creditworthy. Each repurchase agreement is recorded at cost. The Fund
     requires that the securities purchased in a repurchase agreement be
     transferred to the custodian in a manner sufficient to enable the Fund to
     assert a perfected security interest in those securities in the event of a
     default under the repurchase agreement. The Fund monitors, on a daily
     basis, the value of the securities transferred to ensure that their value,
     including accrued interest, is greater than amounts owed to the Fund under
     each such repurchase agreement.

11   Transactions with other funds managed by Neuberger Berman Management Inc.:
     Pursuant to an Exemptive Order issued by the Securities and Exchange
     Commission, the Fund may invest in the Neuberger Berman Institutional Cash
     Fund (the "Cash Fund"), a fund managed by Management and having the same
     Board members as the Fund. The Cash Fund seeks to provide as high a level
     of current income as is consistent with the preservation of capital and the
     maintenance of liquidity. For any cash that the Fund invests in the Cash
     Fund, Management waives a portion of its management fee equal to the
     management fee it receives from the Cash Fund on those assets. For the six
     months ended June 30, 2004, such waived fees amounted to $1,855. For the
     six months ended June 30, 2004, income earned on this


                                       12





            NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     investment amounted to $14,741 and is reflected in the Statement of
     Operations under the caption Income from investments in affiliated issuers.

12   Other: All net investment income and realized and unrealized capital gains
     and losses of the Fund are allocated, on the basis of relative net assets,
     pro rata among its respective classes.

     Note B--Management Fees, Administration Fees, Distribution Arrangements,
     and Other Transactions With Affiliates:

     Fund shares are issued and redeemed in connection with investments in and
     payments under certain variable annuity contracts and variable life
     insurance policies issued through separate accounts of life insurance
     companies and are also offered directly to qualified pension and retirement
     plans.

     The Fund retains Management as its investment manager under a Management
     Agreement. For such investment management services, the Fund pays
     Management a fee at the annual rate of 0.55% of the first $250 million of
     the Fund's average daily net assets, 0.525% of the next $250 million, 0.50%
     of the next $250 million, 0.475% of the next $250 million, 0.45% of the
     next $500 million, 0.425% of the next $2.5 billion, and 0.40% of average
     daily net assets in excess of $4 billion.

     The Fund retains Management as its administrator under an Administration
     Agreement. Each class pays Management an administration fee at the annual
     rate of 0.30% of its average daily net assets under this agreement.
     Additionally, Management retains State Street as its sub-administrator
     under a Sub-Administration Agreement. Management pays State Street a fee
     for all services received under the agreement.

     The Trustees of the Trust adopted a non-fee distribution plan for the
     Fund's Class I.

     For the Fund's Class S, Management acts as agent in arranging for the sale
     of class shares without commission and bears advertising and promotion
     expenses. The Trustees of the Trust have adopted a distribution plan (the
     "Plan") with respect to this class, pursuant to Rule 12b-1 under the 1940
     Act. The Plan provides that, as compensation for administrative and other
     services provided to this class, Management's activities and expenses
     related to the sale and distribution of this class of shares, and ongoing
     services provided to investors in this class, Management receives from this
     class a fee at the annual rate of 0.25% of Class S's average daily net
     assets. Management receives this amount to provide distribution and
     shareholder servicing for this class and pays a portion of it to
     institutions that provide such services. Those institutions may use the
     payments for, among other purposes, compensating employees engaged in sales
     and/or shareholder servicing. The amount of fees paid by this class during
     any year may be more or less than the cost of distribution and other
     services provided to this class. NASD rules limit the amount of annual
     distribution fees that may be paid by a mutual fund and impose a ceiling on
     the cumulative distribution fees paid. The Trust's Plan complies with those
     rules.

     Management has contractually undertaken through December 31, 2007 to
     reimburse the Fund's Class I and Class S shares for their operating
     expenses (excluding the fees payable to Management (including the fees
     payable to Management with respect to the Fund's Class S shares), interest,
     taxes, brokerage commissions, extraordinary expenses, and transaction
     costs) ("Operating Expenses") which exceed, in the


                                       13





Notes to Financial Statements Guardian Portfolio cont'd
- -------------------------------------------------------

     aggregate, 1.00% and 1.25%, respectively, per annum of their average daily
     net assets (the "Expense Limitation"). For the six months ended June 30,
     2004, no reimbursement to the Fund's Class I and Class S shares was
     required. The Fund's Class I and Class S shares each have agreed to repay
     Management through December 31, 2010 for their excess Operating Expenses
     previously reimbursed by Management, so long as their annual Operating
     Expenses during that period do not exceed their Expense Limitations, and
     the repayments are made within three years after the year in which
     Management issued the reimbursement.. During the six months ended June 30,
     2004, there was no reimbursement to Management. At June 30, 2004, the
     Fund's Class I and Class S shares have no contingent liability to
     Management under these agreements.

     On October 31, 2003, Management and Neuberger, a member firm of the New
     York Stock Exchange and sub-adviser to the Fund, became indirect
     wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a
     publicly-owned holding company. Neuberger is retained by Management to
     furnish it with investment recommendations and research information without
     added cost to the Fund. Several individuals who are officers and/or
     Trustees of the Trust are also employees of Neuberger and/or Management.

     On July 1, 2003, the Fund entered into a commission recapture program,
     which enables it to pay some of its operational expenses by recouping a
     portion of the commissions it pays to a broker that is not a related party
     of the Fund. Expenses paid through this program may include costs of
     custodial, transfer agency or accounting services. For the six months ended
     June 30, 2004, the impact of this arrangement was a reduction of $6,002.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. The impact of this arrangement, reflected in the Statement of
     Operations under the caption Custodian fees, was a reduction of $14.

     Note C--Securities Transactions:

     During the six months ended June 30, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $20,758,203 and
     $26,766,016, respectively.

     During the six months ended June 30, 2004, brokerage commissions on
     securities transactions amounted to $78,374, of which Neuberger received
     $0, Lehman received $16,045 and other brokers received $62,329.

     Note E--Line of Credit:

     At June 30, 2004, the Fund was a participant in a single committed,
     unsecured $150,000,000 line of credit with State Street, to be used only
     for temporary or emergency purposes. Interest is charged on borrowings
     under this agreement at the overnight Federal Funds Rate plus 0.50% per
     annum. A facility fee of 0.10% per annum of the available line of credit is
     charged, of which the Fund has agreed to pay its pro rata share, based on
     the ratio of its individual net assets to the net assets of all
     participants at the time the fee is due and payable. The fee is paid
     quarterly in arrears. No compensating balance is required. Other investment
     companies managed by Management also participate in this line of credit on
     the same terms. Because several investment companies participate, there is
     no assurance that the Fund will have access to the entire $150,000,000 at
     any particular time. The Fund had no loans outstanding pursuant to this
     line of credit at June 30, 2004, nor had the Fund utilized this line of
     credit at any time prior to that date.

     Note F--Unaudited Financial Information:

     The financial information included in this interim report is taken from the
     records of the Fund without audit by independent auditors. Annual reports
     contain audited financial statements.

Notes to Financial Highlights Guardian Portfolio
- ------------------------------------------------

+    The per share amounts and ratios which are shown reflect income and
     expenses, including the Fund's Class I proportionate share of AMT Guardian
     Investment's income and expenses through April 30, 2000 under the prior
     master/feeder fund structure.

++   Total return based on per share net asset value reflects the effects of
     changes in net asset value on the performance of the Fund during each
     fiscal period and assumes dividends and other distributions, if any, were
     reinvested. Results represent past performance and do not guarantee future
     results. Current returns may be lower or higher than the performance data
     quoted. Investment returns and principal may fluctuate and shares when
     redeemed may be worth more or less than original cost. Total return would
     have been lower/higher if Management had not waived/recouped certain
     expenses. The total return information shown does not reflect charges and
     other expenses that apply to the separate account or the related insurance
     policies, and the inclusion of these charges and other expenses would
     reduce the total return for all fiscal periods shown. Performance data
     current to the most recent month-end are available at www.nb.com.

#    The Fund is required to calculate an expense ratio without taking into
     consideration any expense reductions related to expense offset
     arrangements.

sec  After reimbursement of expenses previously paid by the investment manager.
     Had the investment manager not been reimbursed, the annualized ratios of
     net expenses to average daily net assets would have been:

                                       Year Ended December 31,
                                     2001        2000        1999

     Guardian Portfolio Class I       .97%        .99%        .98%

     After waiver of a portion of the investment management fee. Had Management
     not undertaken such action, the annualized ratios of net expenses to
     average daily net assets would have been:

                                      Six Months     Year Ended
                                  Ended June 30,   December 31,
                                            2004           2003

     Guardian Portfolio Class S             1.21%          1.22%

^    The date investment operations commenced.

++   The per share amounts which are shown have been computed based on the
     average number of shares outstanding during each fiscal period.

*    Annualized.

**   Not annualized.

- -    The amounts shown at this caption for a share outstanding may not acord
     with the change in aggregate gains and losses in securities for the fiscal
     period because of the timing of sales and repurchases of class shares in
     relation to fluctuating market values for the Fund.

Limited Maturity Bond Portfolio Managers' Commentary

For the six months ended June 30, 2004, the Neuberger Berman AMT Limited
Maturity Bond Portfolio returned 0.00%, compared to a -0.08% decline for the
Merrill Lynch 1-3 Year Treasury Index benchmark.(2)

At the beginning of 2004, the portfolio had a relatively conservative duration
of 1.3 years, moderately below the duration of the benchmark index. The
portfolio's defensive posture was a reflection of our recognition that low bond
yields provide only a thin cushion to offset potential price declines
associated with the strengthening economy. We maintained the portfolio's
conservative positioning throughout the reporting period, a stance that helped
preserve shareholder capital following the surprisingly strong March employment
report and the Federal Reserve's anticipated interest rate hike in June.

We employed shifts in sector allocation to take advantage of evolving
opportunities in the market. Over the reporting period, we reduced our
allocation to corporate securities from 49.6% of the portfolio at the beginning
of the period to 39.8% at the end of June. We also steadily increased our
allocation to U.S. Treasury Securities from 37.9% of the portfolio on December
31, 2003, to 45.0% at the end of June, which helped to maintain the portfolio's
high credit quality. These changes are consistent with the conservative
structuring of the portfolio.

As expected, the Federal Reserve Board's Open Market Committee took action by
moving the Fed Funds target rate up 0.25% at its June 30 meeting. In the past,
Fed Chairman Alan Greenspan has employed a measured approach to adjusting the
target rate, taking small discrete steps and then patiently waiting to evaluate
the impact on the economy before proceeding further. In his commentary, Mr.
Greenspan has hinted that the Fed will use a similar approach in the coming
months. We will continue to evaluate these factors and adjust the portfolio
accordingly.

At the end of this reporting period (June 30, 2004) the portfolio had a
duration of 1.3 years versus approximately 1.7 years for the Merrill Lynch 1-3
Year Treasury Index benchmark, an average Credit Quality Rating of AA, and an
Average Yield to Maturity of 2.68%.

In closing, with short-term interest rates reaching historically low levels,
investors in our fund have enjoyed relatively strong returns over the past few
years. In this lower interest rate environment we are taking a conservative
approach and protecting these gains. As interest rates rise and additional
opportunities become more attractive, we will once again reach out on the risk
spectrum in search of ways to create value in the fund.

Sincerely,

                                /s/ Ted Giuliano

1. 0.49%, 4.86% and 5.18% were the average annual total returns for the 1-, 5-
and 10-year periods ended June 30, 2004. Neuberger Berman Management Inc.
("NBMI") has agreed to absorb certain expenses of the AMT Portfolios. Without
this arrangement, which is subject to change, the total returns of the
Portfolios would be less. Total return includes reinvestment of dividends and
capital gain distributions. Performance data quoted represent past performance
and the investment return and principal value of an investment will fluctuate
so that the shares, when redeemed, may be worth more or less than original
cost. Current performance may be lower or higher than the performance data
quoted. For performance data current to the most recent month end, please visit
www.nb.com/amtperformance. The performance information does not reflect fees
and expenses of the variable annuity and variable life insurance policies or
the pension plans whose proceeds are invested in the portfolio.

2. The Merrill Lynch 1-3 Year U.S. Treasury Index is an unmanaged total return
market value index consisting of all coupon-bearing U.S. Treasury publicly
placed debt securities with maturities between 1 to 3 years. Please note that
indices do not take into account any fees and expenses of investing in the
individual securities that they track, and that individuals cannot invest
directly in any index. Data about the performance of this index are prepared or
obtained by NBMI and include reinvestment of all dividends and capital gain
distributions. The Portfolio may invest in many securities not included in the
above-described index.

The composition, industries and holdings of the Portfolio are subject to
change.

The investments for the Portfolio are managed by the same portfolio manager(s)
who manage one or more other mutual funds that have similar names, investment
objectives and investment styles as the Portfolio. You should be aware that the
Portfolio is likely to differ from the other mutual funds in size, cash flow
pattern and tax matters. Accordingly, the holdings and performance of the
Portfolio can be expected to vary from those of the other mutual funds.

Shares of the separate Portfolios of Neuberger Berman Advisers Management Trust
are sold only through the currently effective prospectus and are not available
to the general public. Shares of this Portfolio may be purchased only by life
insurance companies to be used in their separate accounts that fund variable
annuity and variable life insurance policies and by qualified pension and
retirement plans.

Notes to Schedule of Investments Limited Maturity Bond Portfolio

+    Investments in securities by the Fund are valued daily by obtaining bid
     price quotations from independent pricing services on all securities
     available in each service's data base. For all other securities requiring
     daily quotations, bid prices are obtained from principal market makers in
     those securities or, if quotations are not available, by a method the Board
     of Trustees of Neuberger Berman Advisers Management Trust believes
     accurately reflects fair value. Numerous factors may be considered when
     determining the fair value of a security, including available analyst,
     media or other reports, trading in futures or ADRs and whether the issuer
     of the security being fair valued has other securities outstanding. Foreign
     security prices are furnished by independent quotation services expressed
     in local currency values. Foreign security prices are translated from the
     local currency into U.S. dollars using the exchange rate as of 12:00 p.m.,
     Eastern time. Short-term debt securities with less than 60 days until
     maturity may be valued at cost which, when combined with interest earned,
     approximates market value.

#    At cost, which approximates market value.

##   At June 30, 2004, the cost of investments for U.S. Federal income tax
     purposes was $315,338,135. Gross unrealized appreciation of investments was
     $1,066,701 and gross unrealized depreciation of investments was $1,262,683,
     resulting in net unrealized depreciation of $195,982, based on cost for
     U.S. Federal income tax purposes.

**   Security exempt from registration under the Securities Act of 1933. These
     securities may be resold in transactions exempt from registration, normally
     to qualified institutional buyers under Rule 144A. At June 30, 2004, these
     securities amounted to $4,086,272 or 1.3% of net assets.

\o   Security purchased on a when-issued basis. At June 30, 2004, these
     securities amounted to $6,296,875.

\o\o Security is segregated as collateral for when-issued purchase commitments
     and financial futures contracts margin.

^    Principal amount is stated in the currency in which the security is
     denominated.

e    TBA (To Be Assigned) Securities are purchased on a forward commitment basis
     with an approximate principal amount and no definite maturity date. The
     actual principal amount and maturity date will be determined upon
     settlement when the specific mortgage pools are assigned.

Notes to Financial Statements Limited Maturity Bond Portfolio

Note A--Summary of Significant Accounting Policies:

1 General: Limited Maturity Bond Portfolio (the "Fund") is a separate operating
series of Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware
statutory trust organized pursuant to a Trust Instrument dated May 23, 1994.
The Trust is currently comprised of ten separate operating series (each a
"Series," collectively, the "Funds") each of which (except Focus Portfolio) is
diversified. The Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act"),
and its shares are registered under the Securities Act of 1933, as amended. The
Fund currently offers only Class I shares. The Board of Trustees of the Trust
may establish additional series or classes of shares without the approval of
shareholders.

The assets of each Series belong only to that Series, and the liabilities of
each Series are borne solely by that Series and no other.

The preparation of financial statements in accordance with accounting
principles generally accepted in the United States requires Neuberger Berman
Management Inc. ("Management") to make estimates and assumptions at the date of
the financial statements. Actual results could differ from those estimates.

2 Portfolio valuation: Investment securities are valued as indicated in the
notes following the Schedule of Investments.

3 Foreign currency translation: The accounting records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars using the exchange rate as of 12:00 p.m., Eastern time, to determine
the value of investments, other assets and liabilities. Purchase and sale
prices of securities, and income and expenses, are translated into U.S. dollars
at the prevailing rate of exchange on the respective dates of such
transactions. Net unrealized foreign currency gain (loss) arises from changes
in the value of assets and liabilities, other than investments in securities,
as a result of changes in exchange rates and is stated separately in the
Statement of Operations.

4 Securities transactions and investment income: Securities transactions are
recorded on a trade date basis. Interest income, including accretion of
original issue discount, where applicable, and accretion of market discount on
long-term bonds and short-term investments, is recorded on the accrual basis.
Realized gains and losses from securities transactions and foreign currency
transactions are recorded on the basis of identified cost and stated separately
in the Statement of Operations.

5 Forward foreign currency contracts: The Fund may enter into forward foreign
currency contracts ("contracts") in connection with planned purchases or sales
of securities to hedge the U.S. dollar value of portfolio securities
denominated in a foreign currency. The gain or loss arising from the difference
between the original contract price and the closing price of such contract is
included in net realized gains or losses on foreign currency transactions.
Fluctuations in the value of forward foreign currency contracts are recorded
for financial reporting purposes as unrealized gains or losses by the Fund. The
Fund has no specific limitation on the percentage of assets which may be
committed to these types of contracts but the Fund may not invest more than 25%
of its total assets in foreign securities denominated in or indexed to


                                       10





            NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

foreign currencies. The Fund could be exposed to risks if a counter party to a
contract were unable to meet the terms of its contract or if the value of the
foreign currency changes unfavorably. The U.S. dollar value of foreign currency
underlying all contractual commitments held by the Fund is determined using
forward foreign currency exchange rates supplied by an independent pricing
service.

6 Financial futures contracts: The Fund may buy and sell financial futures
contracts to hedge against changes in securities prices resulting from changes
in prevailing interest rates. At the time the Fund enters into a financial
futures contract, it is required to deposit with its custodian a specified
amount of cash or liquid securities, known as "initial margin," ranging upward
from 1.1% of the value of the financial futures contract being traded. Each
day, the futures contract is valued at the official settlement price of the
board of trade or U.S. commodity exchange on which such futures contract is
traded. Subsequent payments, known as "variation margin," to and from the
broker are made on a daily basis as the market price of the financial futures
contract fluctuates. Daily variation margin adjustments, arising from this
"mark to market," are recorded by the Fund as unrealized gains or losses.

Although some financial futures contracts by their terms call for actual
delivery or acceptance of financial instruments, in most cases the contracts
are closed out prior to delivery by offsetting purchases or sales of matching
financial futures contracts.When the contracts are closed, the Fund recognizes
a gain or loss. Risks of entering into futures contracts include the
possibility there may be an illiquid market and/or a change in the value of the
contract may not correlate with changes in the value of the underlying
securities.

For U.S. Federal income tax purposes, the futures transactions undertaken by
the Fund may cause the Fund to recognize gains or losses from marking to market
even though its positions have not been sold or terminated, may affect the
character of the gains or losses recognized as long-term or short-term, and may
affect the timing of some capital gains and losses realized by the Fund. Also,
the Fund's losses on transactions involving futures contracts may be deferred
rather than being taken into account currently in calculating the Fund's
taxable income.

During the six months ended June 30, 2004, the Fund entered into various
financial futures contracts. At June 30, 2004, open positions in financial
futures contracts were as follows:

                                                                      Unrealized
    Expiration                    Open Contracts     Position       Depreciation

September 2004   415 U.S. Treasury Notes, 5 Year        Short           $348,749

At June 30, 2004, the Fund had deposited $765,000 U.S. Treasury Notes, 1.63%,
due 3/31/05, in a segregated account to cover margin requirements on open
financial futures contracts.

7 Federal income taxes: The Funds are treated as separate entities for U.S.
Federal income tax purposes. It is the policy of the Fund to continue to
qualify as a regulated investment company by complying with the provisions
available to certain investment companies, as defined in applicable sections of
the Internal Revenue Code, and to make distributions of investment company
taxable income and net capital gains (after reduction for any amounts available
for U.S. Federal income tax purposes as capital loss carryforwards) sufficient
to relieve it from all, or substantially all, U.S. Federal income taxes.
Accordingly, the Fund paid no U.S. Federal income taxes and no provision for
U.S. Federal income taxes was required.

8 Dividends and distributions to shareholders: The Fund earns income, net of
expenses, daily on its investments. Income dividends and distributions from net
realized capital gains, if any, generally are distributed in October. Income
dividends and capital gain distributions to shareholders are recorded on the
ex-dividend date.To the extent the Fund's net realized capital gains, if any,
can be offset by capital loss carryforwards ($21,426, $2,478,607, $3,975,890
and $6,386,624 expiring in 2005, 2006, 2007 and 2008, respectively, determined
as of December 31, 2003), it is the policy of the Fund not to distribute such
gains.

Under current tax law, certain capital and net foreign currency losses realized
after October 31 within the taxable year may be deferred and treated as
occurring on the first day of the following tax year. For the year ended
December 31, 2003, the Fund elected to defer $286,603 of net capital and
currency losses arising between November 1, 2003 and December 31, 2003.

The Fund distinguishes between dividends on a tax basis and a financial
reporting basis and only distributions in excess of tax basis earnings and
profits are reported in the financial statements as a tax return of capital.
Differences in the recognition or classification of income between the
financial statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or accumulated net realized
gains in the components of net assets on the Statement of Assets and
Liabilities.

The tax character of distributions paid during the years ended December 31,
2003 and 2002 was as follows:

Distributions Paid From:
          Ordinary Income                        Total
          2003             2002             2003             2002

   $14,350,033      $14,469,639      $14,350,033      $14,469,639

As of December 31, 2003, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:

  Undistributed       Unrealized             Loss
       Ordinary     Appreciation    Carryforwards
         Income   (Depreciation)    and Deferrals         Total

    $11,799,768       $1,053,303     $(13,149,150)    $(296,079)

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales, foreign bond bifurcation,
amortization of bond premium, and post October losses.

9 Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
tax authorities, net of refunds recoverable.

10 Expense allocation: Certain expenses are applicable to multiple funds.
Expenses directly attributable to a Series are charged to that Series. Expenses
of the Trust that are not directly attributed to a Series are allocated among
the Funds, on the basis of relative net assets, except where a more appropriate
allocation of expenses to each of the Funds can otherwise be made fairly.
Expenses borne by the complex of related investment companies, which includes
open-end and closed-end investment companies for which Management serves as
investment manager, that are not directly attributed to a Series or the Trust,
are allocated among the Fund and the other investment companies in the complex
or series thereof, on the

            NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

basis of relative net assets, except where a more appropriate allocation of
expenses to each investment company in the complex or series thereof can
otherwise be made fairly.

11 Repurchase agreements: The Fund may enter into repurchase agreements with
institutions that the Fund's investment manager has determined are
creditworthy. Each repurchase agreement is recorded at cost. The Fund requires
that the securities purchased in a repurchase agreement be transferred to the
custodian in a manner sufficient to enable the Fund to assert a perfected
security interest in those securities in the event of a default under the
repurchase agreement. The Fund monitors, on a daily basis, the value of the
securities transferred to ensure that their value, including accrued interest,
is greater than amounts owed to the Fund under each such repurchase agreement.

Note B--Management Fees, Administration Fees, Distribution Arrangements, and
Other Transactions With Affiliates:

Fund shares are issued and redeemed in connection with investments in and
payments under certain variable annuity contracts and variable life insurance
policies issued through separate accounts of life insurance companies and are
also offered directly to qualified pension and retirement plans.

The Fund retains Management as its investment manager under a Management
Agreement. For such investment management services, the Fund pays Management a
fee at the annual rate of 0.25% of the first $500 million of the Fund's average
daily net assets, 0.225% of the next $500 million, 0.20% of the next $500
million, 0.175% of the next $500 million, and 0.15% of average daily net assets
in excess of $2 billion.

The Fund retains Management as its administrator under an Administration
Agreement. The Fund pays Management an administration fee at the annual rate of
0.40% of its average daily net assets under this agreement. Additionally,
Management retains State Street Bank and Trust Company ("State Street") as its
sub-administrator under a Sub-Administration Agreement. Management pays State
Street a fee for all services received under the agreement.

The Trustees of the Trust adopted a non-fee distribution plan for the Fund.

Management has contractually undertaken through December 31, 2007 to reimburse
the Fund for its operating expenses (excluding the fees payable to Management,
interest, taxes, brokerage commissions, extraordinary expenses, and transaction
costs) ("Operating Expenses") which exceed, in the aggregate, 1.00% per annum
of its average daily net assets (the "Expense Limitation"). For the six months
ended June 30, 2004, no reimbursement to the Fund was required. The Fund has
agreed to repay Management through December 31, 2010 for its excess Operating
Expenses previously reimbursed by Management, so long as its annual Operating
Expenses during that period do not exceed its Expense Limitation, and the
repayment is made within three years after the year in which Management issued
the reimbursement. During the six months ended June 30, 2004, there was no
reimbursement to Management. At June 30, 2004, the Fund has no contingent
liability to Management under the agreement.

Notes to Financial Statements Limited Maturity Bond Portfolio cont'd

On October 31, 2003, Management and Neuberger Berman, LLC ("Neuberger"), a
member firm of the New York Stock Exchange and sub-adviser to the Fund, became
indirect wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"),
a publicly-owned holding company. Neuberger is retained by Management to
furnish it with investment recommendations and research information without
added cost to the Fund. Several individuals who are officers and/or Trustees of
the Trust are also employees of Neuberger and/or Management.

The Fund has an expense offset arrangement in connection with its custodian
contract. The impact of this arrangement, reflected in the Statement of
Operations under the caption Custodian fees, was a reduction of $214.

            NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

Note E--Line of Credit:

At June 30, 2004, the Fund was a participant in a single committed, unsecured
$150,000,000 line of credit with State Street, to be used only for temporary or
emergency purposes. Interest is charged on borrowings under this agreement at
the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.10%
per annum of the available line of credit is charged, of which the Fund has
agreed to pay its pro rata share, based on the ratio of its individual net
assets to the net assets of all participants at the time the fee is due and
payable. The fee is paid quarterly in arrears. No compensating balance is
required. Other investment companies managed by Management also participate in
this line of credit on the same terms. Because several investment companies
participate, there is no assurance that the Fund will have access to the entire
$150,000,000 at any particular time. The Fund had no loans outstanding pursuant
to this line of credit at June 30, 2004, nor had the Fund utilized this line of
credit at any time prior to that date.

Note F--Unaudited Financial Information:

The financial information included in this interim report is taken from the
records of the Fund without audit by independent auditors. Annual reports
contain audited financial statements.

Notes to Financial Highlights Limited Maturity Bond Portfolio

+    The per share amounts and ratios which are shown reflect income and
     expenses, including the Fund's proportionate share of AMT Limited Maturity
     Bond Investment's income and expenses through April 30, 2000 under the
     prior master/feeder fund structure.

++   Total return based on per share net asset value reflects the effects of
     changes in net asset value on the performance of the Fund during each
     fiscal period and assumes dividends and other distributions, if any, were
     reinvested. Results represent past performance and do not guarantee future
     results. Current returns may be lower or higher than the performance data
     quoted. Investment returns and principal may fluctuate and shares when
     redeemed may be worth more or less than original cost. The total return
     information shown does not reflect charges and other expenses that apply to
     the separate account or the related insurance policies, and the inclusion
     of these charges and other expenses would reduce the total return for all
     fiscal periods shown. Performance data current to the most recent month-end
     are available at www.nb.com.

#    The Fund is required to calculate an expense ratio without taking into
     consideration any expense reductions related to expense offset
     arrangements.

++   The per share amounts which are shown have been computed based on the
     average number of shares outstanding during each fiscal period.

- -    For fiscal years ended after December 31, 2000, funds are required by the
     American Institute of Certified Public Accountants to amortize premiums and
     discounts on fixed income securities. Accordingly, for the year ended
     December 31, 2001, the per share amounts and ratios shown decreased or
     increased as follows:

Mid-Cap Growth Portfolio Managers' Commentary

The AMT Mid-Cap Growth Portfolio ended the first half of 2004 with a gain of
7.50%, outperforming the Russell Midcap Growth index return of 5.94%.(2) This
outperformance reflected the fact that the market began rewarding stocks with
solid business fundamentals as opposed to unproven growth prospects, a trend
that favored our investment process. Our stock selection boosted our
performance across most sectors of the portfolio.

The largest contribution to relative performance came from stock selection in
the information technology, consumer discretionary and financial sectors.
Stocks that did well in IT included companies that develop and provide
specialized technologies to businesses such as Zebra Technologies. Within
consumer discretionary, our emphasis in entertainment and leisure and specialty
retail companies were some of the primary reasons for this outperformance with
Royal Caribbean Cruises and PETsMART both performing well. Within the
financials sector, Capital One Financial, First Marblehead, and Investors
Financial Services were all strong performers, as they represent less interest
rate sensitive names within that sector.

In the aggregate, our sector allocation was slightly negative on a year-to-date
basis, with our underweight position in both consumer staples and healthcare
accounting for much of the underperformance.

After beginning the year with strong advances, the market began trading
sideways during the second quarter. In the aggregate, for the first half of
2004, the markets have confounded consensus expectations by trading in very
narrow ranges with only a 7% swing on the Standard & Poor's 500 Index. As we
anticipated early in the year, the equity markets have experienced substantial
rotation between cyclical (materials/technology) and defensive
(healthcare/staples) industries/sectors as investors reacted to the shifting
economic news.

Economic forecasting is exceptionally difficult this year as we formulate the
top-down part of our strategy. In addition to the initiation of a tightening
cycle by the Fed, we face the expiration of some tax cuts this year, a slowing
Chinese economy, U.S. political uncertainty and volatile oil prices. Like a pig
in a python, the lower dollar, faster than expected U.S. growth and the strong
Asian demand for commodities last year are working their way through the system
and causing rates of inflation to accelerate this year. We believe that many of
these influences have dissipated, however, so the Fed may not need to react as
strongly as investors fear.

As investors grapple with higher inflation and the expected continuing interest
rate hikes by the Fed, worries are also growing that the economy is slowing.
Recently, Wal-Mart, Target and General Motors lowered their top-line forecasts.
Similar to our view on inflation, we are also relatively sanguine about
economic growth. It is important to note that while overall growth is fine, the
composition of economic activity is changing from a mortgage refinanced/lower
tax consumer-led recovery to one being sustained by corporate investment,
inventory building and steady job creation.

Even though we are not pessimistic in terms of the overall economy and
inflation, we are not optimistic in terms of near-term stock performance. We
expect equities to struggle as profit growth slows, interest rates increase,
and the Presidential election remains tight. Over the past six years, the S&P
500 is essentially flat in price while earnings have increased by a third. The
market's forward P/E has collapsed from 21 to 16 during this period. However,
the stock market is still not cheap, since a P/E of 16 is the long-term
average. We believe P/Es will continue to wilt in the heat of the summer
months. Uncertainties about next year's economy will most likely increase as


                                       1





more difficult earnings comparisons will begin this quarter. If fears become
more intense and investors overreact, we expect poor near-term equity
performance to provide a platform for better equity performance in the latter
part of this year.

We have reduced our position in the materials sector to an underweight relative
to the benchmark on the basis of our concerns that global growth rates have
peaked. Industrials and energy remain moderately overweighted, financials
moderately underweighted, utilities underweighted, and other sectors relatively
neutral weighted.

We seek to continue to position the portfolio with tilts toward lower
volatility stocks in higher quality companies with lower earnings variability.
As interest rates move higher and growth rates slow, we believe that companies
with financial strength should be favored.

Sincerely,

                               /s/ JON D. BRORSON

1. For Class I, 22.71%, (0.14%) and 8.33% were the average annual total returns
for the 1-year, 5-year and since inception (11/03/97) periods ended June 30,
2004. For Class S, 22.46%, (0.22%) and 8.26% were the average annual total
returns for the 1-year, 5-year and since inception (11/03/97) periods ended June
30, 2004. Performance shown prior to February 2003 for the Class S shares is of
the Class I shares, which has lower expenses and typically higher returns than
the Class S shares. Neuberger Berman Management Inc. ("NBMI") has agreed to
absorb certain expenses of the AMT Portfolios. Without this arrangement, which
is subject to change, the total returns of the Portfolios would be less. Total
return includes reinvestment of dividends and capital gain distributions.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)


Notes to Schedule of Investments Mid-Cap Growth Portfolio

+  Investments in equity securities by the Fund are valued at the latest sales
   price where that price is readily available; securities for which no sales
   were reported, unless otherwise noted, are valued at the mean between the
   closing bid and asked prices. Securities traded primarily on the NASDAQ Stock
   Market are normally valued by the Fund at the NASDAQ Official Closing Price
   ("NOCP") provided by NASDAQ each business day. The NOCP is the most recently
   reported price as of 4:00:02 p.m., Eastern time, unless that price is outside
   the range of the "inside" bid and asked prices (i.e., the bid and asked
   prices that dealers quote to each other when trading for their own accounts);
   in that case, NASDAQ will adjust the price to equal the inside bid or asked
   price, whichever is closer. Because of delays in reporting trades, the NOCP
   may not be based on the price of the last trade to occur before the market
   closes. The Fund values all other securities by a method the Board of
   Trustees of Neuberger Berman Advisers Management Trust (the "Board") believes
   accurately reflects fair value. Numerous factors may be considered when
   determining the fair value of a security, including available analyst, media
   or other reports, trading in futures or ADRs and whether the issuer of the
   security being fair valued has other securities outstanding. Foreign security
   prices are furnished by independent quotation services expressed in local
   currency values. Foreign security prices are translated from the local
   currency into U.S. dollars using the exchange rate as of 12:00 p.m., Eastern
   time. The Board has approved the use of FT Interactive Data Corporation ("FT
   Interactive") to assist in determining the fair value of the Fund's foreign
   equity securities in the wake of certain significant events. Specifically,
   when changes in the value of a certain index suggest that the closing prices
   on the foreign exchanges no longer represent the amount that the Fund could
   expect to receive for those securities, FT Interactive will provide adjusted
   prices for certain foreign equity securities based on an analysis showing
   historical correlations between the prices of those securities and changes in
   the index. In the absence of precise information about the market values of
   these foreign securities as of the close of the New York Stock Exchange, the
   Board has determined on the basis of available data that prices adjusted in
   this way are likely to be closer to the prices the Fund could realize on a
   current sale than are the prices of those securities established at the close
   of the foreign markets in which the securities primarily trade. However, fair
   value prices are necessarily estimates, and there is no assurance that such a
   price will be at or close to the price at which the security next trades.
   Short-term debt securities with less than 60 days until maturity may be
   valued at cost which, when combined with interest earned, approximates market
   value.

#  At cost, which approximates market value.

## At June 30, 2004, the cost of investments for U.S. Federal income tax
   purposes was $533,073,451. Gross unrealized appreciation of investments was
   $116,372,343 and gross unrealized depreciation of investments was $5,497,635,
   resulting in net unrealized appreciation of $110,874,708, based on cost for
   U.S. Federal income tax purposes.

*  Non-income producing security.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)


Notes to Financial Statements Mid-Cap Growth Portfolio

Note A--Summary of Significant Accounting Policies:

1 General: Mid-Cap Growth Portfolio (the "Fund") is a separate operating series
of Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware
statutory trust organized pursuant to a Trust Instrument dated May 23, 1994.
The Trust is currently comprised of ten separate operating series (each a
"Series," collectively, the "Funds") each of which (except Focus Portfolio) is
diversified. The Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act"),
and its shares are registered under the Securities Act of 1933, as amended (the
"1933 Act"). The Fund currently offers Class I and Class S shares. Class S had
no operations until February 18, 2003, other than matters relating to its
organization and registration of its shares under the 1933 Act. The Board of
Trustees of the Trust may establish additional series or classes of shares
without the approval of shareholders.

The assets of each Series belong only to that Series, and the liabilities of
each Series are borne solely by that Series and no other.

The preparation of financial statements in accordance with accounting
principles generally accepted in the United States requires Neuberger Berman
Management Inc. ("Management") to make estimates and assumptions at the date of
the financial statements. Actual results could differ from those estimates.

2 Portfolio valuation: Investment securities are valued as indicated in the
notes following the Schedule of Investments.

3 Foreign currency translation: The accounting records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars using the exchange rate as of 12:00 p.m., Eastern time, to determine
the value of investments, other assets and liabilities. Purchase and sale
prices of securities, and income and expenses, are translated into U.S. dollars
at the prevailing rate of exchange on the respective dates of such
transactions. Net unrealized foreign currency gain (loss) arises from changes
in the value of assets and liabilities, other than investments in securities,
as a result of changes in exchange rates and is stated separately in the
Statement of Operations.

4 Securities transactions and investment income: Securities transactions are
recorded on a trade date basis. Dividend income is recorded on the ex-dividend
date or, for certain foreign dividends, as soon as the Fund becomes aware of
the dividends. Non-cash dividends included in dividend income, if any, are
recorded at the fair market value of the securities received. Interest income,
including accretion of original issue discount, where applicable, and accretion
of discount on short-term investments, is recorded on the accrual basis.
Realized gains and losses from securities transactions and foreign currency
transactions are recorded on the basis of identified cost and stated separately
in the Statement of Operations. Included in net realized gain (loss) on
investment securities sold are proceeds from the settlements of class action
litigation in which the Fund participated as a plaintiff. The amount of such
proceeds for the six months ended June 30, 2004 was $2,420.


                                       12





Notes to Financial Statements Mid-Cap Growth Portfolio cont'd

5 Federal income taxes: The Funds are treated as separate entities for U.S.
Federal income tax purposes. It is the policy of the Fund to continue to
qualify as a regulated investment company by complying with the provisions
available to certain investment companies, as defined in applicable sections of
the Internal Revenue Code, and to make distributions of investment company
taxable income and net capital gains (after reduction for any amounts available
for U.S. Federal income tax purposes as capital loss carryforwards) sufficient
to relieve it from all, or substantially all, U.S. Federal income taxes.
Accordingly, the Fund paid no U.S. Federal income taxes and no provision for
U.S. Federal income taxes was required.

6 Dividends and distributions to shareholders: The Fund may earn income, net of
expenses, daily on its investments. Income dividends and distributions from net
realized capital gains, if any, generally are distributed in October. Income
dividends and capital gain distributions to shareholders are recorded on the
ex-dividend date. To the extent the Fund's net realized capital gains, if any,
can be offset by capital loss carryforwards ($4,181,334, $236,225,757,
$113,423,118 and $11,059,423 expiring in 2008, 2009, 2010 and 2011,
respectively, determined as of December 31, 2003), it is the policy of the Fund
not to distribute such gains.

The Fund distinguishes between dividends on a tax basis and a financial
reporting basis and only distributions in excess of tax basis earnings and
profits are reported in the financial statements as a tax return of capital.
Differences in the recognition or classification of income between the
financial statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or accumulated net realized
gains in the components of net assets on the Statement of Assets and
Liabilities.

As of December 31, 2003, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:

                                Unrealized                Loss
                              Appreciation       Carryforwards
                            (Depreciation)       and Deferrals            Total

                               $93,111,385      $(364,889,632)   $(271,778,247)

The difference between book basis and tax basis is attributable primarily to
net operating losses and the tax deferral of losses on wash sales.

7 Expense allocation: Certain expenses are applicable to multiple funds.
Expenses directly attributable to a Series are charged to that Series. Expenses
of the Trust that are not directly attributed to a Series are allocated among
the Funds, on the basis of relative net assets, except where a more appropriate
allocation of expenses to each of the Funds can otherwise be made fairly.
Expenses borne by the complex of related investment companies, which includes
open-end and closed-end investment companies for which Management serves as
investment manager, that are not directly attributed to a Series or the Trust,
are allocated among the Fund and the other investment companies in the complex
or series thereof, on the basis of relative net assets, except where a more
appropriate allocation of expenses to each investment company in the complex or
series thereof can otherwise be made fairly. The Fund's expenses (other than
those specific to each class) are allocated proportionally each day between the
classes based upon the relative net assets of each class.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)


8 Security lending: Pursuant to an Exemptive Order issued by the Securities and
Exchange Commission, the Fund entered into a Securities Lending Agreement
("Agreement") with Neuberger Berman, LLC ("Neuberger") on April 17, 2003.
Securities loans involve certain risks in the event a borrower should fail
financially, including delays or inability to recover the lent securities or
foreclose against the collateral. The investment manager, under the general
supervision of the Trust's Board of Trustees, monitors the creditworthiness of
the parties to whom the Fund makes security loans. The Fund will not lend
securities on which covered call options have been written, or lend securities
on terms which would prevent the Fund from qualifying as a regulated investment
company. The Fund receives cash collateral equal to at least 102% of the
current market value of the loaned securities. The Fund invests the cash
collateral in the N&B Securities Lending Quality Fund, LLC, which is managed by
State Street Bank and Trust Company ("State Street") pursuant to guidelines
approved by the Trust's investment manager. Neuberger guaranteed minimum
revenue to the Fund under the Agreement, and received a portion of any revenue
earned in excess of the guaranteed amount as a lending agency fee.

The Agreement has been renewed and approved by the Board of Trustees as of July
1, 2004 with substantially the same terms. Under this current Agreement,
Neuberger guarantees minimum revenue to the Fund and receives any revenue
earned in excess of the guaranteed amount as a lending agency fee.

At June 30, 2004, the Fund had not paid Neuberger any fees under the Agreement.

Income earned on the securities loaned, if any, is reflected in the Statement
of Operations under the caption Income from securities loaned-net.

9 Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
tax authorities, net of refunds recoverable.

10 Transactions with other funds managed by Neuberger Berman Management Inc.:
Pursuant to an Exemptive Order issued by the Securities and Exchange
Commission, the Fund may invest in the Neuberger Berman Institutional Cash Fund
(the "Cash Fund"), a fund managed by Management and having the same Board
members as the Fund. The Cash Fund seeks to provide as high a level of current
income as is consistent with the preservation of capital and the maintenance of
liquidity. For any cash that the Fund invests in the Cash Fund, Management
waives a portion of its management fee equal to the management fee it receives
from the Cash Fund on those assets. For the six months ended June 30, 2004,
such waived fees amounted to $5,772. For the six months ended June 30, 2004,
income earned on this investment amounted to $45,702 and is reflected in the
Statement of Operations under the caption Income from investments in affiliated
issuers.

11 Repurchase agreements: The Fund may enter into repurchase agreements with
institutions that the Fund's investment manager has determined are
creditworthy. Each repurchase agreement is recorded at cost. The Fund requires
that the securities purchased in a repurchase agreement be transferred to the
custodian in a manner sufficient to enable the Fund to assert a perfected
security interest in those securities in the event of a default under the
repurchase agreement. The Fund monitors, on a daily basis, the value of the
securities transferred to ensure that their value, including accrued interest,
is greater than amounts owed to the Fund under each such repurchase agreement.


                                       14





Notes to Financial Statements Mid-Cap Growth Portfolio cont'd

12 Other: All net investment income and realized and unrealized capital gains
and losses of the Fund are allocated, on the basis of relative net assets, pro
rata among its respective classes.

Note B--Management Fees, Administration Fees, Distribution Arrangements, and
Other Transactions With Affiliates:

Fund shares are issued and redeemed in connection with investments in and
payments under certain variable annuity contracts and variable life insurance
policies issued through separate accounts of life insurance companies and are
also offered directly to qualified pension and retirement plans.

The Fund retains Management as its investment manager under a Management
Agreement. For such investment management services, the Fund pays Management a
fee at the annual rate of 0.55% of the first $250 million of the Fund's average
daily net assets, 0.525% of the next $250 million, 0.50% of the next $250
million, 0.475% of the next $250 million, 0.45% of the next $500 million,
0.425% of the next $2.5 billion, and 0.40% of average daily net assets in
excess of $4 billion.

The Fund retains Management as its administrator under an Administration
Agreement. The Fund pays Management an administration fee at the annual rate of
0.30% of its average daily net assets under this agreement. Additionally,
Management retains State Street as its sub-administrator under a
Sub-Administration Agreement. Management pays State Street a fee for all
services received under the agreement.

The Trustees of the Trust adopted a non-fee distribution plan for the Fund's
Class I.

For the Fund's Class S, Management acts as agent in arranging for the sale of
class shares without commission and bears advertising and promotion expenses.
The Trustees of the Trust have adopted a distribution plan (the "Plan") with
respect to this class, pursuant to Rule 12b-1 under the 1940 Act. The Plan
provides that, as compensation for administrative and other services provided
to this class, Management's activities and expenses related to the sale and
distribution of this class of shares, and ongoing services provided to
investors in this class, Management receives from this class a fee at the
annual rate of 0.25% of Class S's average daily net assets. Management receives
this amount to provide distribution and shareholder servicing for this class
and pays a portion of it to institutions that provide such services. Those
institutions may use the payments for, among other purposes, compensating
employees engaged in sales and/or shareholder servicing. The amount of fees
paid by this class during any year may be more or less than the cost of
distribution and other services provided to this class. NASD rules limit the
amount of annual distribution fees that may be paid by a mutual fund and impose
a ceiling on the cumulative distribution fees paid. The Trust's Plan complies
with those rules.

Management has contractually undertaken through December 31, 2007 to reimburse
the Fund's Class I and Class S shares for their operating expenses (excluding
the fees payable to Management (including the fees payable to Management with
respect to the Fund's Class S shares), interest, taxes, brokerage commissions,
extraordinary expenses, and transaction costs) ("Operating Expenses") which
exceed, in the aggregate, 1.00% and 1.25%, respectively, per annum of their
average daily net assets (the "Expense Limitation"). For the six months ended
June 30, 2004, no reimbursement to the Fund's Class I and Class S shares was
required. The Fund's Class I and Class S shares each have agreed to repay
Management

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

through December 31, 2010 for their excess Operating Expenses previously
reimbursed by Management, so long as their annual Operating Expenses during
that period do not exceed their Expense Limitations, and the repayments are
made within three years after the year in which Management issued the
reimbursement. During the six months ended June 30, 2004, there was no
reimbursement to Management. At June 30, 2004, the Fund's Class I and Class S
shares have no contingent liability to Management under these agreements.

On October 31, 2003, Management and Neuberger, a member firm of the New York
Stock Exchange and sub-adviser to the Fund, became indirect wholly-owned
subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned
holding company. Neuberger is retained by Management to furnish it with
investment recommendations and research information without added cost to the
Fund. Several individuals who are officers and/or Trustees of the Trust are
also employees of Neuberger and/or Management.

On July 1, 2003, the Fund entered into a commission recapture program, which
enables it to pay some of its operational expenses by recouping a portion of
the commissions it pays to a broker that is not a related party of the Fund.
Expenses paid through this program may include costs of custodial, transfer
agency or accounting services. For the six months ended June 30, 2004, the
impact of this arrangement was a reduction of $56,931.

The Fund has an expense offset arrangement in connection with its custodian
contract. The impact of this arrangement, reflected in the Statement of
Operations under the caption Custodian fees, was a reduction of $40.

Note C--Securities Transactions:

During the six months ended June 30, 2004, there were purchase and sale
transactions (excluding short-term securities) of $228,561,390 and
$236,619,556, respectively.

During the six months ended June 30, 2004, brokerage commissions on securities
transactions amounted to $672,478, of which Neuberger received $8, Lehman
received $137,306, and other brokers received $535,164.

Note D--Fund Share Transactions:

Share activity for the six months ended June 30, 2004 and for the year ended

Notes to Financial Statements Mid-Cap Growth Portfolio cont'd

Note E--Line of Credit:

At June 30, 2004, the Fund was a participant in a single committed, unsecured
$150,000,000 line of credit with State Street, to be used only for temporary or
emergency purposes. Interest is charged on borrowings under this agreement at
the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.10%
per annum of the available line of credit is charged, of which the Fund has
agreed to pay its pro rata share, based on the ratio of its individual net
assets to the net assets of all participants at the time the fee is due and
payable. The fee is paid quarterly in arrears. No compensating balance is
required. Other investment companies managed by Management also participate in
this line of credit on the same terms. Because several investment companies
participate, there is no assurance that the Fund will have access to the entire
$150,000,000 at any particular time. The Fund had no loans outstanding pursuant
to this line of credit at June 30, 2004, nor had the Fund utilized this line of
credit at any time prior to that date.

Note F--Unaudited Financial Information:

The financial information included in this interim report is taken from the
records of the Fund without audit by independent auditors. Annual reports
contain audited financial statements.

+     The per share amounts and ratios which are shown reflect income and
      expenses, including the Fund's Class I proportionate share of AMT Mid-Cap
      Growth Investment's income and expenses through April 30, 2000 under the
      prior master/feeder fund structure.

++    Total return based on per share net asset value reflects the effects of
      changes in net asset value on the performance of the Fund during each
      fiscal period and assumes dividends and other distributions, if any, were
      reinvested. Results represent past performance and do not guarantee future
      results. Current returns may be lower or higher than the performance data
      quoted. Investment returns and principal may fluctuate and shares when
      redeemed may be worth more or less than original cost. Total return would
      have been lower if Management had not reimbursed and/or waived certain
      expenses. Total return would have been higher if Management had not
      recouped previously reimbursed expenses. The total return information
      shown does not reflect charges and other expenses that apply to the
      separate account or the related insurance policies, and the inclusion of
      these charges and other expenses would reduce the total return for all
      fiscal periods shown. Performance data current to the most recent
      month-end are available at www.nb.com.

Partners Portfolio Manager's Commentary


We are pleased to report that the Partners Portfolio modestly outperformed its
benchmarks, the Standard & Poor's 500 Index and the Russell 1000 Value Index,
in the first half of 2004.(2)

With investors obsessing over rising interest rates, Iraq, terrorism, and the
November elections, and largely ignoring excellent corporate earnings growth,
stocks made only modest progress in the first half of 2004.

Investments in the energy, industrials, and financials sectors had the most
favorable impact on returns. Although we were underweighted in energy relative
to the Russell 1000 Value Index benchmark, the performance of our holdings
nearly doubled the benchmark energy component returns. We got a "double play"
from industrials, where we were overweighted and our stock selections also
outperformed by a substantial margin. We were underweighted in financials and
returns were modest compared to our energy and industrial sector investments,
but once again stock selection contributed meaningfully to portfolio
performance.

Consumer discretionary sector investments disappointed. We were overweight in
consumer discretionary, the worst performing sector in the first half, and our
holdings underperformed the benchmark component. We missed the ball in consumer
staples, due to our focus on valuation. Our average weighting in staples was
about 1.5% compared to 7.4% for the Russell 1000 Value Index and 11.2% for the
S&P 500. Being so underweighted in the second best performing sector during
this six-month reporting period penalized relative returns.

Looking ahead to the second half of 2004 and to 2005, we expect the economy to
successfully make the transition from a monetary and fiscal stimulus generated
recovery to a somewhat slower growth self-sustaining expansion. Although
corporate earnings growth will slow from the torrid pace of the first and
second quarters, we expect at least high single digit percentage earnings gains
for the S&P 500 over the next year, making the S&P's current price/forward
earnings multiple of 16 more than reasonable. Oil prices are the biggest threat
to this scenario. We believe the economy can absorb $35-$40 per barrel oil, but
may stall if oil prices get much higher.

Our overweighting versus the Russell 1000 Value Index in the consumer
discretionary sector is a reflection of our economic outlook and the fact that
we are finding high quality companies trading at what we view as bargain
prices. Economists and market strategists have underestimated the consumer for
the past four years, citing dozens of reasons for an imminent decline in
consumer spending. Although the reasons being given today--rising interest
rates, no more tax relief, and the end of the home refinancing boom--may slow
consumer spending, we don't think the consumer will roll over. Consumer debt is
high, but prices and financing costs will likely remain low. We note that one
bad month of auto sales in June brought back big incentives including lower
sticker prices and cut-rate financing packages.

Although our weighting in the consumer discretionary sector hasn't changed much
over the last year, we have shifted our emphasis from retailers to advertising
supported media companies. Media stocks have disappointed due to the fact that
ad spending has not yet rebounded with the economy. It never does, because
companies don't increase their advertising budgets until they are confident an
economic recovery has legs. That confidence is now growing and we believe ad
spending will accelerate in the second half of 2004. The homebuilders have been
beaten down in recent months due to concerns that rising mortgage rates will
slow the housing market. Because supply/demand dynamics are so favorable--there
is only about three months of inventory of new homes--


                                        1





and because we believe mortgage rates will remain relatively low, we think the
high quality home builders will continue to prosper.

We are now nearly equal weighted in energy, because we think it may be quite
some time before supply can catch up to demand. India and China alone have
contributed to most of the incremental demand for oil. We have yet to see a
supply side response to higher oil prices in the form of substantially
increased exploration and production activity. Until we see more money spent to
increase oil reserves and production, oil prices will very likely remain
stubbornly high. This is not good for the economy, but it is good for energy
company shareholders.

At the close of the first half of 2004, our largest weightings are in
financials, consumer discretionary, healthcare, industrials and technology
sectors, in that order. We think this is a good balance between economically
sensitive, higher growth sectors (consumer discretionary and technology) that
should do well if the economy meets our expectations and more stable growth
sectors (healthcare and financials) which should provide ballast for the
portfolio should the economy weaken more than we anticipate. Of course, stock
selection will remain the key to superior returns.


Sincerely,

PORTFOLIO MANAGER


1. 20.94%, 0.03% and 11.23% were the average annual total returns for the
1-year, 5-year and 10-year periods ended June 30, 2004. Neuberger Berman
Management Inc. ("NBMI") has agreed to absorb certain expenses of the AMT
Portfolios. Without this arrangement, which is subject to change, the total
returns of the Portfolios would be less. Total return includes reinvestment of
dividends and capital gain distributions. Performance data quoted represent
past performance and the investment return and principal value of an investment
will fluctuate so that the shares, when redeemed, may be worth more or less
than original cost. Current performance may be lower or higher than the
performance data quoted. For performance data current to the most recent month
end, please visit www.nb.com/amtperformance. The performance information does
not reflect fees and expenses of the variable annuity and variable life
insurance policies or the pension plans whose proceeds are invested in the
portfolio.

2. The S&P 500 Index is widely regarded as the standard for measuring large-cap
U.S. stock market performance and includes a representative sample of leading
companies in leading industries. The Russell 1000[RegTM] Index measures the
performance of the 1,000 largest companies in the Russell 3000[RegTM] Index
(which measures the performance of the 3,000 largest U.S. companies based on
total market capitalization). The Russell 1000 Index represents approximately
92% of the total market capitalization of the Russell 3000 Index. The Russell
1000 Value Index measures the performance of those Russell 1000 companies with
lower price-to-book ratios and lower forecasted growth values. Please note that
indices do not take into account any fees and expenses of investing in the
individual securities that they track, and that individuals cannot invest
directly in any index. Data about the performance of these indices are prepared
or obtained by NBMI and include reinvestment of all dividends and capital gain
distributions. The Portfolio may invest in many securities not included in the
above-described indices.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)


Notes to Schedule of Investments Partners Portfolio

+    Investments in equity securities by the Fund are valued at the latest sales
     price where that price is readily available; securities for which no sales
     were reported, unless otherwise noted, are valued at the mean between the
     closing bid and asked prices. Securities traded primarily on the NASDAQ
     Stock Market are normally valued by the Fund at the NASDAQ Official Closing
     Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most
     recently reported price as of 4:00:02 p.m., Eastern time, unless that price
     is outside the range of the "inside" bid and asked prices (i.e., the bid
     and asked prices that dealers quote to each other when trading for their
     own accounts); in that case, NASDAQ will adjust the price to equal the
     inside bid or asked price, whichever is closer. Because of delays in
     reporting trades, the NOCP may not be based on the price of the last trade
     to occur before the market closes. The Fund values all other securities by
     a method the Board of Trustees of Neuberger Berman Advisers Management
     Trust (the "Board") believes accurately reflects fair value. Numerous
     factors may be considered when determining the fair value of a security,
     including available analyst, media or other reports, trading in futures or
     ADRs and whether the issuer of the security being fair valued has other
     securities outstanding. Foreign security prices are furnished by
     independent quotation services expressed in local currency values. Foreign
     security prices are translated from the local currency into U.S. dollars
     using the exchange rate as of 12:00 p.m., Eastern time. The Board has
     approved the use of FT Interactive Data Corporation ("FT Interactive") to
     assist in determining the fair value of the Fund's foreign equity
     securities in the wake of certain significant events. Specifically, when
     changes in the value of a certain index suggest that the closing prices on
     the foreign exchanges no longer represent the amount that the Fund could
     expect to receive for those securities, FT Interactive will provide
     adjusted prices for certain foreign equity securities based on an analysis
     showing historical correlations between the prices of those securities and
     changes in the index. In the absence of precise information about the
     market values of these foreign securities as of the close of the New York
     Stock Exchange, the Board has determined on the basis of available data
     that prices adjusted in this way are likely to be closer to the prices the
     Fund could realize on a current sale than are the prices of those
     securities established at the close of the foreign markets in which the
     securities primarily trade. However, fair value prices are necessarily
     estimates, and there is no assurance that such a price will be at or close
     to the price at which the security next trades. Short-term debt securities
     with less than 60 days until maturity may be valued at cost which, when
     combined with interest earned, approximates market value.

#    At cost, which approximates market value.

##   At June 30, 2004, the cost of investments for U.S. Federal income tax
     purposes was $667,037,627. Gross unrealized appreciation of investments was
     $117,749,299 and gross unrealized depreciation of investments was
     $9,133,105, resulting in net unrealized appreciation of $108,616,194, based
     on cost for U.S. Federal income tax purposes.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)


Notes to Financial Statements Partners Portfolio

Note A--Summary of Significant Accounting Policies:

1 General: Partners Portfolio (the "Fund") is a separate operating series of
Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware statutory
trust organized pursuant to a Trust Instrument dated May 23, 1994. The Trust is
currently comprised of ten separate operating series (each a "Series,"
collectively, the "Funds") each of which (except Focus Portfolio) is
diversified. The Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act"),
and its shares are registered under the Securities Act of 1933, as amended. The
Fund currently offers only Class I shares. The Board of Trustees of the Trust
may establish additional series or classes of shares without the approval of
shareholders.

The assets of each Series belong only to that Series, and the liabilities of
each Series are borne solely by that Series and no other.

The preparation of financial statements in accordance with accounting
principles generally accepted in the United States requires Neuberger Berman
Management Inc. ("Management") to make estimates and assumptions at the date of
the financial statements. Actual results could differ from those estimates.

2 Portfolio valuation: Investment securities are valued as indicated in the
notes following the Schedule of Investments.

3 Foreign currency translation: The accounting records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars using the exchange rate as of 12:00 p.m., Eastern time, to determine
the value of investments, other assets and liabilities. Purchase and sale
prices of securities, and income and expenses, are translated into U.S. dollars
at the prevailing rate of exchange on the respective dates of such
transactions. Net unrealized foreign currency gain (loss) arises from changes
in the value of assets and liabilities, other than investments in securities,
as a result of changes in exchange rates and is stated separately in the
Statement of Operations.

4 Securities transactions and investment income: Securities transactions are
recorded on a trade date basis. Dividend income is recorded on the ex-dividend
date or, for certain foreign dividends, as soon as the Fund becomes aware of
the dividends. Non-cash dividends included in dividend income, if any, are
recorded at the fair market value of the securities received. Interest income,
including accretion of original issue discount, where applicable, and accretion
of discount on short-term investments, is recorded on the accrual basis.
Realized gains and losses from securities transactions and foreign currency
transactions are recorded on the basis of identified cost and stated separately
in the Statement of Operations. Included in net realized gain (loss) on
investment securities sold are proceeds from the settlements of class action
litigation in which the Fund participated as a plaintiff. The amount of such
proceeds for the six months ended June 30, 2004 was $726,010.

5 Federal income taxes: The Funds are treated as separate entities for U.S.
Federal income tax purposes. It is the policy of the Fund to continue to
qualify as a regulated investment company by complying with the provisions
available to certain investment companies, as defined in applicable sections of
the Internal


                                       12





Notes to Financial Statements Partners Portfolio cont'd

Revenue Code, and to make distributions of investment company taxable income
and net capital gains (after reduction for any amounts available for U.S.
Federal income tax purposes as capital loss carryforwards) sufficient to
relieve it from all, or substantially all, U.S. Federal income taxes.
Accordingly, the Fund paid no U.S. Federal income taxes and no provision for
U.S. Federal income taxes was required.

6 Dividends and distributions to shareholders: The Fund may earn income, net of
expenses, daily on its investments. Income dividends and distributions from net
realized capital gains, if any, generally are distributed in October. Income
dividends and capital gain distributions to shareholders are recorded on the
ex-dividend date. To the extent the Fund's net realized capital gains, if any,
can be offset by capital loss carryforwards ($9,141,747, $72,177,018 and
$20,760,081 expiring in 2009, 2010 and 2011, respectively, determined as of
December 31, 2003), it is the policy of the Fund not to distribute such gains.

The Fund distinguishes between dividends on a tax basis and a financial
reporting basis and only distributions in excess of tax basis earnings and
profits are reported in the financial statements as a tax return of capital.
Differences in the recognition or classification of income between the
financial statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or accumulated net realized
gains in the components of net assets on the Statement of Assets and
Liabilities.

The tax character of distributions paid during the years ended December 31,
2003 and 2002 was as follows:




Distributions Paid From:
                                                           Long-Term              Tax Return
                               Ordinary Income           Capital Gain             of Capital                  Total
                            2003             2002      2003       2002       2003           2002      2003             2002
                                                                                      
                           $  --       $3,518,207     $  --      $  --      $  --       $169,184     $  --       $3,687,391



As of December 31, 2003, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:

   Undistributed           Unrealized                  Loss
        Ordinary         Appreciation         Carryforwards
          Income       (Depreciation)         and Deferrals              Total

         $59,567         $133,256,253         $(102,078,846)       $31,236,974

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7 Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
tax authorities, net of refunds recoverable.

8 Expense allocation: Certain expenses are applicable to multiple funds.
Expenses directly attributable to a Series are charged to that Series. Expenses
of the Trust that are not directly attributed to a Series are allocated among
the Funds, on the basis of relative net assets, except where a more appropriate
allocation of expenses to each of the Funds can otherwise be made fairly.
Expenses borne by the complex of related investment companies, which includes
open-end and closed-end investment companies for which Management serves as
investment manager, that are not directly attributed to a Series or the Trust,
are

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

allocated among the Fund and the other investment companies in the complex or
series thereof, on the basis of relative net assets, except where a more
appropriate allocation of expenses to each investment company in the complex or
series thereof can otherwise be made fairly.

9 Repurchase agreements: The Fund may enter into repurchase agreements with
institutions that the Fund's investment manager has determined are
creditworthy. Each repurchase agreement is recorded at cost. The Fund requires
that the securities purchased in a repurchase transaction be transferred to the
custodian in a manner sufficient to enable the Fund to assert a perfected
security interest in those securities in the event of a default under the
repurchase agreement. The Fund monitors, on a daily basis, the value of the
securities transferred to ensure that their value, including accrued interest,
is greater than amounts owed to the Fund under each such repurchase agreement.

10 Security lending: Pursuant to an Exemptive Order issued by the Securities
and Exchange Commission, the Fund entered into a Securities Lending Agreement
("Agreement") with Neuberger Berman, LLC ("Neuberger") on April 17, 2003.
Securities loans involve certain risks in the event a borrower should fail
financially, including delays or inability to recover the lent securities or
foreclose against the collateral. The investment manager, under the general
supervision of the Trust's Board of Trustees, monitors the creditworthiness of
the parties to whom the Fund makes security loans. The Fund will not lend
securities on which covered call options have been written, or lend securities
on terms which would prevent the Fund from qualifying as a regulated investment
company. The Fund receives cash collateral equal to at least 102% of the
current market value of the loaned securities. The Fund invests the cash
collateral in the N&B Securities Lending Quality Fund, LLC, which is managed by
State Street Bank and Trust Company ("State Street") pursuant to guidelines
approved by the Trust's investment manager. Neuberger guaranteed minimum
revenue to the Fund under the Agreement, and received a portion of any revenue
earned in excess of the guaranteed amount as a lending agency fee.

The Agreement has been renewed and approved by the Board of Trustees as of July
1, 2004 with substantially the same terms. Under this current Agreement,
Neuberger guarantees minimum revenue to the Fund and receives any revenue
earned in excess of the guaranteed amount as a lending agency fee.

At June 30, 2004, the Fund had not paid Neuberger any fees under the Agreement.

Income earned on the securities loaned, if any, is reflected in the Statement
of Operations under the caption Income from securities loaned-net.

11 Transactions with other funds managed by Neuberger Berman Management Inc.:
Pursuant to an Exemptive Order issued by the Securities and Exchange
Commission, the Fund may invest in the Neuberger Berman Institutional Cash Fund
(the "Cash Fund"), a fund managed by Management and having the same Board
members as the Fund. The Cash Fund seeks to provide as high a level of current
income as is consistent with the preservation of capital and the maintenance of
liquidity. For any cash that the Fund invests in the Cash Fund, Management
waives a portion of its management fee equal to the management fee it receives
from the Cash Fund on those assets. For the six months ended June 30, 2004,
such waived fees amounted to $7,873. For the six months ended June 30, 2004,
income earned on this

investment amounted to $61,887 and is reflected in the Statement of Operations
under the caption Income from investments in affiliated issuers.

Note B--Management Fees, Administration Fees, Distribution Arrangements, and
Other Transactions With Affiliates:

Fund shares are issued and redeemed in connection with investments in and
payments under certain variable annuity contracts and variable life insurance
policies issued through separate accounts of life insurance companies and are
also offered directly to qualified pension and retirement plans.

The Fund retains Management as its investment manager under a Management
Agreement. For such investment management services, the Fund pays Management a
fee at the annual rate of 0.55% of the first $250 million of the Fund's average
daily net assets, 0.525% of the next $250 million, 0.50% of the next $250
million, 0.475% of the next $250 million, 0.45% of the next $500 million,
0.425% of the next $2.5 billion, and 0.40% of average daily net assets in
excess of $4 billion.

The Fund retains Management as its administrator under an Administration
Agreement. The Fund pays Management an administration fee at the annual rate of
0.30% of its average daily net assets under this agreement. Additionally,
Management retains State Street as its sub-administrator under a
Sub-Administration Agreement. Management pays State Street a fee for all
services received under the agreement.

The Trustees of the Trust adopted a non-fee distribution plan for the Fund.

Management has contractually undertaken through December 31, 2007 to reimburse
the Fund for its operating expenses (excluding the fees payable to Management,
interest, taxes, brokerage commissions, extraordinary expenses, and transaction
costs) ("Operating Expenses") which exceed, in the aggregate, 1.00% per annum
of its average daily net assets (the "Expense Limitation"). For the six months
ended June 30, 2004, no reimbursement to the Fund was required. The Fund has
agreed to repay Management through December 31, 2010 for its excess Operating
Expenses previously reimbursed by Management, so long as its annual Operating
Expenses during that period do not exceed its Expense Limitation, and the
repayment is made within three years after the year in which Management issued
the reimbursement. During the six months ended June 30, 2004, there was no
reimbursement to Management. At June 30, 2004, the Fund has no contingent
liability to Management under the agreement.

On October 31, 2003, Management and Neuberger, a member firm of the New York
Stock Exchange and sub-adviser to the Fund, became indirect wholly-owned
subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned
holding company. Neuberger is retained by Management to furnish it with
investment recommendations and research information without added cost to the
Fund. Several individuals who are officers and/or Trustees of the Trust are
also employees of Neuberger and/or Management.

On July 1, 2003, the Fund entered into a commission recapture program, which
enables it to pay some of its operational expenses by recouping a portion of
the commissions it pays to a broker that is not a related party of the Fund.
Expenses paid through this program may include costs of custodial, transfer
agency or

accounting services. For the six months ended June 30, 2004, the impact of this
arrangement was a reduction of $55,026.

The Fund has an expense offset arrangement in connection with its custodian
contract. The impact of this arrangement, reflected in the Statement of
Operations under the caption Custodian fees, was a reduction of $255.


Note C--Securities Transactions:

During the six months ended June 30, 2004, there were purchase and sale
transactions (excluding short-term securities) of $223,970,761 and
$305,223,576, respectively.

During the six months ended June 30, 2004, brokerage commissions on securities
transactions amounted to $772,005, of which Neuberger received $0, Lehman
received $153,850, and other brokers received $618,155.

Note E--Line of Credit:

At June 30, 2004, the Fund was a participant in a single committed, unsecured
$150,000,000 line of credit with State Street, to be used only for temporary or
emergency purposes. Interest is charged on borrowings under this agreement at
the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.10%
per annum of the available line of credit is charged, of which the Fund has
agreed to pay its pro rata share, based on the ratio of its individual net
assets to the net assets of all participants at the time the fee is due and
payable. The fee is paid quarterly in arrears. No compensating balance is
required. Other investment companies managed by Management also participate in
this line of credit on the same terms. Because several investment companies
participate, there is no assurance that the Fund will have access to the entire
$150,000,000 at any particular time. The Fund had no loans outstanding pursuant
to this line of credit at June 30, 2004, nor had the Fund utilized this line of
credit at any time prior to that date.

Note F--Unaudited Financial Information:

The financial information included in this interim report is taken from the
records of the Fund without audit by independent auditors. Annual reports

      have been lower if Management had not waived certain expenses. The total
      return information shown does not reflect charges and other expenses that
      apply to the separate account or the related insurance policies, and the

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

Regency Portfolio Manager's Commentary

We are pleased to report that the Regency Portfolio outperformed its benchmark,
the Russell Midcap Value Index, during the first half of 2004.(2)

Despite concern over rising interest rates, high oil prices, Iraq, and global
terrorism, mid-cap stocks made solid progress in the first half of 2004. On a
relative return basis, mid-cap value stocks excelled, with the Russell Midcap
Value Index posting the second best performance of Russell's 21 stock market
indices.

Our investments in the financial, healthcare, and energy sectors had the most
favorable impact on returns. Charter One (acquired by Bank of Scotland's
American subsidiary Citizens Bank) and PMI Group were our best performers in the
financials sector. HMOs Oxford Health Plans (acquired by UnitedHealth) and
Anthem, and hospital company Triad Hospitals were the most notable gainers in
the healthcare category. XTO Energy (the portfolio's largest holding as of June
30, 2004) and Sunoco were our most rewarding investments in the energy sector.

In our opinion, fundamentals and valuations in these three industry groups
remain compelling. The conventional wisdom is that rising interest rates hurt
all financial companies. We believe this simply isn't true. Higher rates don't
necessarily hurt many regional banks. In fact, with most commercial and home
equity loans tied to the prime rate and adjusted monthly, the value of regional
banks' assets can increase as interest rates trend higher. Mortgage insurer PMI
Group, one of our top performers in the first half of 2004, provides another
example of how rising interest rates can help financial companies. Rising home
prices and a boom in mortgage refinance led many of its customers to cancel
their mortgage insurance, or at best created additional costs as new policies
were issued just to keep the same revenue. With mortgage rates moving higher and
the refinance boom ending, PMI's margins and earnings are improving.

Our healthcare sector investments performed quite well in the first half of
2004, but in general, healthcare stocks lagged as investors remained infatuated
with cyclical companies. As the pace of economic growth slows in the quarters
ahead and cyclical companies' earnings growth moderates, we believe investors
will come back to more stable growth sectors such as healthcare. Our healthcare
sector assets are concentrated in hospital companies and HMOs with healthy
balance sheets, stable cash flows, high returns on equity, and realistic
prospects for consistent double-digit earnings growth in the years ahead.

Although energy was the top performing sector in the first half, we think
valuations for selected energy companies remain attractive. While we doubt
$35-plus oil is sustainable, we do believe long-term supply/demand dynamics will
support oil prices in the mid-20s. Some energy stock valuations now reflect this
long-term view, and we took profits as several holdings reached our price
targets. However, we believe our remaining positions still have excellent upside
potential.

We were substantially underweighted in technology and our tech sector
investments declined versus a gain for the tech component of our benchmark. Hard
drive maker Western Digital, which sold off as its two biggest competitors
reported disappointing earnings, was the primary culprit. Over the last five
years, consolidation in the


                                        1





disk drive business has diminished pricing pressure and restored profit margins.
Although this is no longer an explosive growth business, we think a
well-managed, financially strong competitor such as Western Digital can grow
annualized earnings by 10-15% going forward. Adjusted for the $1.40 per share in
net cash on the balance sheet, Western Digital is trading around 7.5 times
trailing earnings. In our view, a high quality company trading at a multiple
discount to its earnings growth rate is a legitimate bargain.

We think that the economy is out of the recovery mode and into a slower growth
expansion phase. This could be bad news for companies whose valuations reflect
rather lofty earnings expectations. We note that several such companies
reporting second quarter earnings in early July sold off because earnings simply
met rather than exceeded published forecasts. However, we think this is a good
environment for value stocks, which by definition don't carry the heavy burden
of optimistic earnings expectations. We are really looking forward to the
upcoming second and third quarter earnings reporting seasons. It will not only
give investors obsessing over macroeconomic issues something more concrete to
think about, but also should call attention to what we believe are the strong
fundamentals of the stocks in our portfolio.


Sincerely,

                               /s/ Andrew Wellington

1. 30.92% and 9.80% were the average annual total returns for the 1-year and
since inception (08/22/01) periods ended June 30, 2004. Neuberger Berman
Management Inc. ("NBMI") has agreed to absorb certain expenses of the AMT
Portfolios. Without this arrangement, which is subject to change, the total
returns of the Portfolios would be less. Total return includes reinvestment of
dividends and capital gain distributions. Performance data quoted represent past
performance and the investment return and principal value of an investment will
fluctuate so that the shares, when redeemed, may be worth more or less than
original cost. Current performance may be lower or higher than the performance
data quoted. For performance data current to the most recent month end, please

fees and expenses of the variable annuity and variable life insurance policies
or the pension plans whose proceeds are invested in the portfolio.

2. The Russell Midcap[RegTM] Value Index measures the performance of those
Russell Midcap[RegTM] Index companies with lower price-to-book ratios and lower
forecasted growth values. The Russell Midcap Index measures the performance of
the 800 smallest companies in the Russell 1000[RegTM] Index, which represents
approximately 27% of the total market capitalization of the Russell 1000 Index
(which, in turn, consists of the 1,000 largest U.S. companies, based on market
capitalization). Please note that indices do not take into account any fees and
expenses of investing in the individual securities that they track, and that
individuals cannot invest directly in any index. Data about the performance of

Notes to Schedule of Investments Regency Portfolio

+  Investments in equity securities by the Fund are valued at the latest sales
   price where that price is readily available; securities for which no sales
   were reported, unless otherwise noted, are valued at the mean between the
   closing bid and asked prices. Securities traded primarily on the NASDAQ Stock
   Market are normally valued by the Fund at the NASDAQ Official Closing Price
   ("NOCP") provided by NASDAQ each business day. The NOCP is the most recently
   reported price as of 4:00:02 p.m., Eastern time, unless that price is outside
   the range of the "inside" bid and asked prices (i.e., the bid and asked
   prices that dealers quote to each other when trading for their own accounts);
   in that case, NASDAQ will adjust the price to equal the inside bid or asked
   price, whichever is closer. Because of delays in reporting trades, the NOCP
   may not be based on the price of the last trade to occur before the market
   closes. The Fund values all other securities by a method the Board of
   Trustees of Neuberger Berman Advisers Management Trust (the "Board") believes
   accurately reflects fair value. Numerous factors may be considered when
   determining the fair value of a security, including available analyst, media
   or other reports, trading in futures or ADRs and whether the issuer of the
   security being fair valued has other securities outstanding. Foreign security
   prices are furnished by independent quotation services expressed in local
   currency values. Foreign security prices are translated from the local
   currency into U.S. dollars using the exchange rate as of 12:00 p.m., Eastern
   time. The Board has approved the use of FT Interactive Data Corporation ("FT
   Interactive") to assist in determining the fair value of the Fund's foreign
   equity securities in the wake of certain significant events. Specifically,
   when changes in the value of a certain index suggest that the closing prices
   on the foreign exchanges no longer represent the amount that the Fund could
   expect to receive for those securities, FT Interactive will provide adjusted
   prices for certain foreign equity securities based on an analysis showing
   historical correlations between the prices of those securities and changes in
   the index. In the absence of precise information about the market values of
   these foreign securities as of the close of the New York Stock Exchange, the
   Board has determined on the basis of available data that prices adjusted in
   this way are likely to be closer to the prices the Fund could realize on a
   current sale than are the prices of those securities established at the close
   of the foreign markets in which the securities primarily trade. However, fair
   value prices are necessarily estimates, and there is no assurance that such a
   price will be at or close to the price at which the security next trades.

Notes to Financial Statements Regency Portfolio

Note A--Summary of Significant Accounting Policies:

1 General: Regency Portfolio (the "Fund") is a separate operating series of
Neuberger Berman Advisers Management Trust (the "Trust"), a Delaware statutory
trust organized pursuant to a Trust Instrument dated May 23, 1994. The Trust is
currently comprised of ten separate operating series (each a "Series,"
collectively, the "Funds") each of which (except Focus Portfolio) is
diversified. The Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act"),
and its shares are registered under the Securities Act of 1933, as amended. The
Fund currently offers only Class I shares. The Board of Trustees of the Trust
may establish additional series or classes of shares without the approval of
shareholders.

The assets of each Series belong only to that Series, and the liabilities of
each Series are borne solely by that Series and no other.

The preparation of financial statements in accordance with accounting principles
generally accepted in the United States requires Neuberger Berman Management
Inc. ("Management") to make estimates and assumptions at the date of the
financial statements. Actual results could differ from those estimates.

2 Portfolio valuation: Investment securities are valued as indicated in the
notes following the Schedule of Investments.

3 Foreign currency translation: The accounting records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars using the exchange rate as of 12:00 p.m., Eastern time, to determine the
value of investments, other assets and liabilities. Purchase and sale prices of
securities, and income and expenses, are translated into U.S. dollars at the
prevailing rate of exchange on the respective dates of such transactions. Net
unrealized foreign currency gain (loss) arises from changes in the value of
assets and liabilities, other than investments in securities, as a result of
changes in exchange rates and is stated separately in the Statement of
Operations.

4 Securities transactions and investment income: Securities transactions are
recorded on a trade date basis. Dividend income is recorded on the ex-dividend
date or, for certain foreign dividends, as soon as the Fund becomes aware of the
dividends. Non-cash dividends included in dividend income, if any, are recorded
at the fair market value of the securities received. Interest income, including
accretion of original issue discount, where applicable, and accretion of
discount on short-term investments, is recorded on the accrual basis. Realized
gains and losses from securities transactions and foreign currency transactions
are recorded on the basis of identified cost and stated separately in the
Statement of Operations.

5 Federal income taxes: The Funds are treated as separate entities for U.S.
Federal income tax purposes. It is the policy of the Fund to continue to qualify
as a regulated investment company by complying with the provisions available to
certain investment companies, as defined in applicable sections of the Internal
Revenue Code, and to make distributions of investment company taxable income and
net capital gains (after reduction for any amounts available for U.S. Federal
income tax purposes as capital loss

carryforwards) sufficient to relieve it from all, or substantially all, U.S.
Federal income taxes. Accordingly, the Fund paid no U.S. Federal income taxes
and no provision for U.S. Federal income taxes was required.

6 Dividends and distributions to shareholders: The Fund may earn income, net of
expenses, daily on its investments. Income dividends and distributions from net
realized capital gains, if any, generally are distributed in October. Income
dividends and capital gain distributions to shareholders are recorded on the
ex-dividend date. To the extent the Fund's net realized capital gains, if any,
can be offset by capital loss carryforwards ($65,315 expiring in 2010,
determined as of December 31, 2003), it is the policy of the Fund not to
distribute such gains.

The Fund distinguishes between dividends on a tax basis and a financial
reporting basis and only distributions in excess of tax basis earnings and
profits are reported in the financial statements as a tax return of capital.
Differences in the recognition or classification of income between the financial
statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or accumulated net realized
gains in the components of net assets on the Statement of Assets and
Liabilities.

The tax character of distributions paid during the years ended December 31, 2003
and 2002 was as follows:

Distributions Paid From:
                                              Tax Return
                      Ordinary Income         of Capital             Total
                      2003       2002      2003       2002      2003       2002

                      $  --   $24,825     $  --    $24,550     $  --    $49,375

As of December 31, 2003, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:

               Undistributed        Unrealized               Loss
                    Ordinary      Appreciation      Carryforwards
                      Income    (Depreciation)      and Deferrals         Total

                     $27,008        $9,619,314          $(65,315)    $9,581,007

The difference between book basis and tax basis is attributable primarily to the
tax deferral of losses on wash sales.

7 Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
tax authorities, net of refunds recoverable.

8 Expense allocation: Certain expenses are applicable to multiple funds.
Expenses directly attributable to a Series are charged to that Series. Expenses
of the Trust that are not directly attributed to a Series are allocated among
the Funds, on the basis of relative net assets, except where a more appropriate
allocation of expenses to each of the Funds can otherwise be made fairly.
Expenses borne by the complex of related investment companies, which includes
open-end and closed-end investment companies for which Management serves as
investment manager, that are not directly attributed to a Series or the Trust,
are allocated among the Fund and the other investment companies in the complex
or series thereof, on the basis of relative net assets, except where a more
appropriate allocation of expenses to each investment company in the complex or
series thereof can otherwise be made fairly.

9 Security lending: Pursuant to an Exemptive Order issued by the Securities and
Exchange Commission, the Fund entered into a Securities Lending Agreement
("Agreement") with Neuberger Berman, LLC ("Neuberger") on April 17, 2003.
Securities loans involve certain risks in the event a borrower should fail
financially, including delays or inability to recover the lent securities or
foreclose against the collateral. The investment manager, under the general
supervision of the Trust's Board of Trustees, monitors the creditworthiness of
the parties to whom the Fund makes security loans. The Fund will not lend
securities on which covered call options have been written, or lend securities
on terms which would prevent the Fund from qualifying as a regulated investment
company. The Fund receives cash collateral equal to at least 102% of the current
market value of the loaned securities. The Fund invests the cash collateral in
the N&B Securities Lending Quality Fund, LLC, which is managed by State Street
Bank and Trust Company ("State Street") pursuant to guidelines approved by the
Trust's investment manager. Neuberger guaranteed minimum revenue to the Fund
under the Agreement, and received a portion of any revenue earned in excess of
the guaranteed amount as a lending agency fee.

The Agreement has been renewed and approved by the Board of Trustees as of July
1, 2004 with substantially the same terms. Under this current Agreement,
Neuberger guarantees minimum revenue to the Fund and receives any revenue earned
in excess of the guaranteed amount as a lending agency fee.

At June 30, 2004, the Fund paid Neuberger $1,085 under the Agreement.

Income earned on the securities loaned, if any, is reflected in the Statement of
Operations under the caption Income from securities loaned-net.

10 Repurchase agreements: The Fund may enter into repurchase agreements with
institutions that the Fund's investment manager has determined are creditworthy.
Each repurchase agreement is recorded at cost. The Fund requires that the
securities purchased in a repurchase agreement be transferred to the custodian
in a manner sufficient to enable the Fund to assert a perfected security
interest in those securities in the event of a default under the repurchase
agreement. The Fund monitors, on a daily basis, the value of the securities
transferred to ensure that their value, including accrued interest, is greater
than amounts owed to the Fund under each such repurchase agreement.

11 Transactions with other funds managed by Neuberger Berman Management Inc.:
Pursuant to an Exemptive Order issued by the Securities and Exchange Commission,
the Fund may invest in the Neuberger Berman Institutional Cash Fund (the "Cash
Fund"), a fund managed by Management and having the same Board members as the
Fund. The Cash Fund seeks to provide as high a level of current income as is
consistent with the preservation of capital and the maintenance of liquidity.
For any cash that the Fund invests in the Cash Fund, Management waives a portion
of its management fee equal to the management fee it receives from the Cash Fund
on those assets. For the six months ended June 30, 2004, such waived fees
amounted to $1,597. For the six months ended June 30, 2004, income earned on
this investment amounted to $12,641 and is reflected in the Statement of
Operations under the caption Income from investments in affiliated issuers.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

Note B--Management Fees, Administration Fees, Distribution Arrangements, and
Other Transactions With Affiliates:

Fund shares are issued and redeemed in connection with investments in and
payments under certain variable annuity contracts and variable life insurance
policies issued through separate accounts of life insurance companies and are
also offered directly to qualified pension and retirement plans.

The Fund retains Management as its investment manager under a Management
Agreement. For such investment management services, the Fund pays Management a
fee at the annual rate of 0.55% of the first $250 million of the Fund's average
daily net assets, 0.525% of the next $250 million, 0.50% of the next $250
million, 0.475% of the next $250 million, 0.45% of the next $500 million, 0.425%
of the next $2.5 billion, and 0.40% of average daily net assets in excess of $4
billion.

The Fund retains Management as its administrator under an Administration
Agreement. The Fund pays Management an administration fee at the annual rate of
0.30% of its average daily net assets under this agreement. Additionally,
Management retains State Street as its sub-administrator under a
Sub-Administration Agreement. Management pays State Street a fee for all
services received under the agreement.

The Trustees of the Trust adopted a non-fee distribution plan for the Fund.

Management has contractually undertaken through December 31, 2007 to reimburse
the Fund for its operating expenses (including the fees payable to Management
but excluding interest, taxes, brokerage commissions, extraordinary expenses,
and transaction costs) ("Operating Expenses") which exceed, in the aggregate,
1.50% per annum of its average daily net assets (the "Expense Limitation"). For
the six months ended June 30, 2004, no reimbursement to the Fund was required.
The Fund has agreed to repay Management through December 31, 2010 for its excess
Operating Expenses previously reimbursed by Management, so long as its annual
Operating Expenses during that period do not exceed its Expense Limitation, and
the repayment is made within three years after the year in which Management
issued the reimbursement. During the six months ended June 30, 2004, there was
no reimbursement to Management. At June 30, 2004, the Fund has no contingent
liability to Management under the agreement.

On October 31, 2003, Management and Neuberger, a member firm of the New York
Stock Exchange and sub-adviser to the Fund, became indirect wholly-owned
subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned
holding company. Neuberger is retained by Management to furnish it with
investment recommendations and research information without added cost to the
Fund. Several individuals who are officers and/or Trustees of the Trust are also
employees of Neuberger and/or Management.

On July 1, 2003, the Fund entered into a commission recapture program, which
enables it to pay some of its operational expenses by recouping a portion of the
commissions it pays to a broker that is not a related party of the Fund.
Expenses paid through this program may include costs of custodial, transfer
agency or

accounting services. For the six months ended June 30, 2004, the impact of this
arrangement was a reduction of $8,581.

The Fund has an expense offset arrangement in connection with its custodian
contract. The impact of this arrangement, reflected in the Statement of
Operations under the caption Custodian fees, was a reduction of $26.

Note C--Securities Transactions:

During the six months ended June 30, 2004, there were purchase and sale
transactions (excluding short-term securities) of $49,120,497 and $26,567,389,
respectively.

During the six months ended June 30, 2004, brokerage commissions on securities
transactions amounted to $102,687, of which Neuberger received $81, Lehman
received $22,890, and other brokers received $79,716.

Note E--Line of Credit:

At June 30, 2004, the Fund was a participant in a single committed, unsecured
$150,000,000 line of credit with State Street, to be used only for temporary or
emergency purposes. Interest is charged on borrowings under this agreement at
the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.10%
per annum of the available line of credit is charged, of which the Fund has
agreed to pay its pro rata share, based on the ratio of its individual net
assets to the net assets of all participants at the time the fee is due and
payable. The fee is paid quarterly in arrears. No compensating balance is
required. Other investment companies managed by Management also participate in
this line of credit on the same terms. Because several investment companies
participate, there is no assurance that the Fund will have access to the entire
$150,000,000 at any particular time. The Fund had no loans outstanding pursuant
to this line of credit at June 30, 2004, nor had the Fund utilized this line of
credit at any time prior to that date.

Note F--Unaudited Financial Information:

The financial information included in this interim report is taken from the
records of the Fund without audit by independent auditors. Annual reports
contain audited financial statements.

      results. Current returns may be lower or higher than the performance data

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

Socially Responsive Portfolio Managers' Commentary
- --------------------------------------------------

In the first six months of 2004, the Socially Responsive Portfolio posted a
positive return, but underperformed its Standard & Poor's 500 Index and Russell
1000 Value Index benchmarks.(2)

During this reporting period, investors seemed to focus on the negatives--the
increased probability of Federal Reserve rate hikes, high oil prices, Iraq, and
the threat of terrorism--instead of the positives--consistently good economic
data and strong corporate earnings growth. Although the leading market indices
stayed in a tight trading range, there was significant volatility within and
across market sectors, creating a difficult environment for investors.

Energy sector investments had the most positive impact on our total returns,
with Newfield Exploration, and Cimarex Energy finishing on our top-ten
performance list. We began accumulating energy stocks when our research
indicated that global demand was outpacing supply, creating an imbalance that
would likely result in higher energy prices and better earnings for energy
companies. That is precisely what happened and we were rewarded for our
commitment to energy stocks. Despite good gains over the last year, we think
selected energy stocks still offer value. The world has been waiting for oil
prices to come down from current levels. Although OPEC has been doing its best
to bring prices down, strikes by oil field workers in Norway and Nigeria, and
pipeline sabotage in Iraq has crimped supply and energy inventories remain low.
With energy demand usually strongest in the second half of the year, we doubt
inventories can be increased sufficiently to bring prices down any time soon.

Healthcare sector investments also contributed to returns, with Millipore,
Quest Diagnostics, and long-standing holding UnitedHealth Group making our
top-ten performance list. UnitedHealth Group, one of our most consistent and
best performers in recent years, is reshaping the healthcare maintenance
organization (HMO) business through innovative, cost effective,
customer-friendly services. For the past five years, UnitedHealth has been
ranked among the highest in its industry for customer satisfaction. The company
provides a personalized approach to healthcare and offers its plan members
comprehensive online medical resources, including the best available disease
management practices, treatments, and alternative care. UnitedHealth has been
able to grow internally by gaining market share from competitors. In addition,
this year it has made two major acquisitions, Mid Atlantic Medical, which
closed in the first quarter, and Oxford Health, which is scheduled to close in
the third quarter. We are confident that UnitedHealth's strong management team
will be able to successfully integrate these acquisitions, enhancing future
growth. Through technological innovation and strategic management decisions,
UnitedHealth is committed to lowering healthcare costs while providing superior
healthcare services supported by evidence-based medicine. As a result, we
believe that UnitedHealth will be part of the solution to addressing our
country's larger healthcare problems.

Our consumer discretionary investments disappointed, with UnitedGlobalCom,
Liberty Media Group, and Comcast retreating. Several factors combined to
pressure Comcast stock. First, investors were discomforted by Comcast's
unsolicited bid for Disney. Then investors became concerned when the Regional
Bell Operating Companies (RBOCs) began discussing new fiber strategies that
could facilitate competing broadband video services. Finally, shareholders
became disappointed when advertising spending failed to rebound along with the
economy. We doubt Comcast will make another run at Disney or try to buy another
"content" company. Although the RBOCs appear serious about competing with cable
companies by offering video services, it will take a lot of time and money for
them to improve their broadband infrastructure to make this possible. Over the
next few years, we believe cable television companies including Comcast will
have more success capturing telephony business from the telephone companies
than the telcos will have winning over cable television subscribers. As a
whole, advertising


                                        1





spending has disappointed. However, due to giant Comcast's (20 million homes
served) interconnection agreements with other large cable television operators,
CATV is now getting a bigger and more profitable share of the advertising
dollar. Gone are the days when cable television advertising was primarily low
cost spots for local businesses. Now they are selling higher cost ads to
national advertisers. This should improve Comcast's and other CATV operators
advertising profits.

The economy appears to be moving from the robust recovery stage to a slower
growth expansion phase. This is an economic environment in which good companies
should be able to distinguish themselves. In 2003's "rising tide lifts all
boats" market, virtually every stock moved higher. Over the last six months,
negative investor sentiment restrained market performance. Barring any
unforeseen event that derails the economy, we believe investor sentiment will
improve and investors will reward companies that execute on their business plans
and deliver solid earnings growth. Put another way, stock selection will be even
more critical in delivering returns. We believe this presents an opportunity for
us to demonstrate the effectiveness of our independent, research driven,
value-oriented discipline, applied in a socially responsive manner.

Sincerely,

                               /s/ Arthur Moretti

1. 17.44%, 2.14% and 4.68% were the average annual total returns for the
1-year, 5-year and since inception (02/18/99) periods ended June 30, 2004.
Neuberger Berman Management Inc. ("NBMI") has agreed to absorb certain expenses
of the AMT Portfolios. Without this arrangement, which is subject to change,
the total returns of the Portfolios would be less. Total return includes
reinvestment of dividends and capital gain distributions. Performance data
quoted represent past performance and the investment return and principal value
of an investment will fluctuate so that the shares, when redeemed, may be worth
more or less than original cost. Current performance may be lower or higher
than the performance data quoted. For performance data current to the most
recent month end, please visit www.nb.com/amtperformance. The performance
information does not reflect fees and expenses of the variable annuity and
variable life insurance policies or the pension plans whose proceeds are
invested in the portfolio.

2. The S&P 500 Index is widely regarded as the standard for measuring large-cap
U.S. stock market performance and includes a representative sample of leading
companies in leading industries. The Russell 1000[RegTM]Index measures the
performance of the 1,000 largest companies in the Russell 3000[RegTM] Index
(which measures the performance of the 3,000 largest U.S. companies based on
total market capitalization). The Russell 1000 Index represents approximately
92% of the total market capitalization of the Russell 3000 Index. The Russell
1000 Value Index measures the performance of those Russell 1000 companies with
lower price-to-book ratios and lower forecasted growth values. Please note that
indices do not take into account any fees and expenses of investing in the
individual securities that they track, and that individuals cannot invest
directly in any index. Data about the performance of these indices are prepared
or obtained by NBMI and include reinvestment of all dividends and capital gain
distributions. The Portfolio may invest in many securities not included in the
above-described indices.

company discussed herein are based on consensus estimates, not Neuberger
Berman's own projections, and they may or may not be realized. In addition, any
revision to a forecast could affect the market price of a security. By quoting
them herein, Neuberger Berman does not offer an opinion as to the accuracy of

objectives and investment styles as the Portfolio. You should be aware that the
Portfolio is likely to differ from the other mutual funds in size, cash flow
pattern and tax matters. Accordingly, the holdings and performance of the
Portfolio can be expected to vary from those of the other mutual funds.

are sold only through the currently effective prospectus and are not available

insurance companies to be used with their separate accounts that fund variable
annuity and variable life insurance policies and by qualified pension and
retirement plans.

+    Investments in equity securities by the Fund are valued at the latest sales
     price where that price is readily available; securities for which no sales
     were reported, unless otherwise noted, are valued at the mean between the
     closing bid and asked prices. Securities traded primarily on the NASDAQ
     Stock Market are normally valued by the Fund at the NASDAQ Official Closing
     Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most
     recently reported price as of 4:00:02 p.m., Eastern time, unless that price
     is outside the range of the "inside" bid and asked prices (i.e., the bid
     and asked prices that dealers quote to each other when trading for their
     own accounts); in that case, NASDAQ will adjust the price to equal the
     inside bid or asked price, whichever is closer. Because of delays in
     reporting trades, the NOCP may not be based on the price of the last trade
     to occur before the market closes. The Fund values all other securities by
     a method the Board of Trustees of Neuberger Berman Advisers Management
     Trust (the "Board") believes accurately reflects fair value. Numerous
     factors may be considered when determining the fair value of a security,
     including available analyst, media or other reports, trading in futures or
     ADRs and whether the issuer of the security being fair valued has other
     securities outstanding. Foreign security prices are furnished by
     independent quotation services expressed in local currency values. Foreign
     security prices are translated from the local currency into U.S. dollars
     using the exchange rate as of 12:00 p.m., Eastern time. The Board has
     approved the use of FT Interactive Data Corporation ("FT Interactive") to
     assist in determining the fair value of the Fund's foreign equity
     securities in the wake of certain significant events. Specifically, when
     changes in the value of a certain index suggest that the closing prices on
     the foreign exchanges no longer represent the amount that the Fund could
     expect to receive for those securities, FT Interactive will provide
     adjusted prices for certain foreign equity securities based on an analysis
     showing historical correlations between the prices of those securities and
     changes in the index. In the absence of precise information about the
     market values of these foreign securities as of the close of the New York
     Stock Exchange, the Board has determined on the basis of available data
     that prices adjusted in this way are likely to be closer to the prices the
     Fund could realize on a current sale than are the prices of those
     securities established at the close of the foreign markets in which the
     securities primarily trade. However, fair value prices are necessarily
     estimates, and there is no assurance that such a price will be at or close
     to the price at which the security next trades. Short-term debt securities
     with less than 60 days until maturity may be valued at cost which, when
     combined with interest earned, approximates market value.

#    At cost, which approximates market value.

##   At June 30, 2004, the cost of investments for U.S. Federal income tax
     purposes was $10,828,070. Gross unrealized appreciation of investments was
     $1,567,560 and gross unrealized depreciation of investments was $66,292,
     resulting in net unrealized appreciation of $1,501,268, based on cost for
     U.S. Federal income tax purposes.

Notes to Financial Statements Socially Responsive Portfolio
- -----------------------------------------------------------

     Note A--Summary of Significant Accounting Policies:

1    General: Socially Responsive Portfolio (the "Fund") is a separate operating
     series of Neuberger Berman Advisers Management Trust (the "Trust"), a
     Delaware statutory trust organized pursuant to a Trust Instrument dated May
     23, 1994. The Trust is currently comprised of ten separate operating series
     (each a "Series," collectively, the "Funds") each of which (except Focus
     Portfolio) is diversified. The Trust is registered as an open-end
     management investment company under the Investment Company Act of 1940, as
     amended (the "1940 Act"), and its shares are registered under the
     Securities Act of 1933, as amended. The Fund currently offers only Class I
     shares. The Board of Trustees of the Trust may establish additional series
     or classes of shares without the approval of shareholders.

     The assets of each Series belong only to that Series, and the liabilities
     of each Series are borne solely by that Series and no other.

     The preparation of financial statements in accordance with accounting
     principles generally accepted in the United States requires Neuberger
     Berman Management Inc. ("Management") to make estimates and assumptions at
     the date of the financial statements. Actual results could differ from
     those estimates.

2    Portfolio valuation: Investment securities are valued as indicated in the
     notes following the Schedule of Investments.

3    Foreign currency translation: The accounting records of the Fund are
     maintained in U.S. dollars. Foreign currency amounts are translated into
     U.S. dollars using the exchange rate as of 12:00 p.m., Eastern time, to
     determine the value of investments, other assets and liabilities. Purchase
     and sale prices of securities, and income and expenses, are translated into
     U.S. dollars at the prevailing rate of exchange on the respective dates of
     such transactions. Net unrealized foreign currency gain (loss) arises from
     changes in the value of assets and liabilities, other than investments in
     securities, as a result of changes in exchange rates and is stated
     separately in the Statement of Operations.

4    Securities transactions and investment income: Securities transactions are
     recorded on a trade date basis. Dividend income is recorded on the
     ex-dividend date or, for certain foreign dividends, as soon as the Fund
     becomes aware of the dividends. Non-cash dividends included in dividend
     income, if any, are recorded at the fair market value of the securities
     received. Interest income, including accretion of original issue discount,
     where applicable, and accretion of discount on short-term investments, is
     recorded on the accrual basis. Realized gains and losses from securities
     transactions and foreign currency transactions are recorded on the basis of
     identified cost and stated separately in the Statement of Operations.

5    Federal income taxes: The Funds are treated as separate entities for U.S.
     Federal income tax purposes. It is the policy of the Fund to continue to
     qualify as a regulated investment company by complying with the provisions
     available to certain investment companies, as defined in applicable
     sections of the Internal Revenue Code, and to make distributions of
     investment company taxable income and net capital gains (after reduction
     for any amounts available for U.S. Federal income tax purposes as capital
     loss


                                       10





      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     carryforwards) sufficient to relieve it from all, or substantially all,
     U.S. Federal income taxes. Accordingly, the Fund paid no U.S. Federal
     income taxes and no provision for U.S. Federal income taxes was required.

6    Dividends and distributions to shareholders: The Fund may earn income, net
     of expenses, daily on its investments. Income dividends and distributions
     from net realized capital gains, if any, generally are distributed in
     October. Income dividends and capital gain distributions to shareholders
     are recorded on the ex-dividend date. To the extent the Fund's net realized
     capital gains, if any, can be offset by capital loss carryforwards
     ($163,765 expiring in 2010, determined as of December 31, 2003), it is the
     policy of the Fund not to distribute such gains.

     The Fund distinguishes between dividends on a tax basis and a financial
     reporting basis and only distributions in excess of tax basis earnings and
     profits are reported in the financial statements as a tax return of
     capital. Differences in the recognition or classification of income between
     the financial statements and tax earnings and profits which result in
     temporary over-distributions for financial statement purposes are
     classified as distributions in excess of net investment income or
     accumulated net realized gains in the components of net assets on the
     Statement of Assets and Liabilities.

     As of December 31, 2003, the components of distributable earnings
     (accumulated losses) on a U.S. Federal income tax basis was as follows:

                                  Unrealized                Loss
                                Appreciation       Carryforwards
                              (Depreciation)       and Deferrals           Total

                                  $1,455,071          $(163,765)      $1,291,306

     The difference between book basis and tax basis is attributable primarily
     to net operating losses, the tax deferral of losses on wash sales and the
     recharacterization of income due to REIT holdings.

7    Expense allocation: Certain expenses are applicable to multiple funds.
     Expenses directly attributable to a Series are charged to that Series.
     Expenses of the Trust that are not directly attributed to a Series are
     allocated among the Funds, on the basis of relative net assets, except
     where a more appropriate allocation of expenses to each of the Funds can
     otherwise be made fairly. Expenses borne by the complex of related
     investment companies, which includes open-end and closed-end investment
     companies for which Management serves as investment manager, that are not
     directly attributed to a Series or the Trust, are allocated among the Fund
     and the other investment companies in the complex or series thereof, on the
     basis of relative net assets, except where a more appropriate allocation of
     expenses to each investment company in the complex or series thereof can
     otherwise be made fairly.

8    Security lending: Pursuant to an Exemptive Order issued by the Securities
     and Exchange Commission, the Fund entered into a Securities Lending
     Agreement ("Agreement") with Neuberger Berman, LLC ("Neuberger") on April
     17, 2003. Securities loans involve certain risks in the event a borrower
     should fail financially, including delays or inability to recover the lent
     securities or foreclose against the collateral. The investment manager,
     under the general supervision of the Trust's Board of Trustees, monitors
     the creditworthiness of the parties to whom the Fund makes security loans.
     The Fund will not lend securities on which covered call options have been
     written, or lend securities on terms which would prevent the Fund from
     qualifying as a regulated investment company. The Fund receives cash
     collateral equal to at


                                       11

     least 102% of the current market value of the loaned securities. The Fund
     invests the cash collateral in the N&B Securities Lending Quality Fund,
     LLC, which is managed by State Street Bank and Trust Company ("State
     Street") pursuant to guidelines approved by the Trust's investment manager.
     Neuberger guaranteed minimum revenue to the Fund under the Agreement, and
     received a portion of any revenue earned in excess of the guaranteed amount
     as a lending agency fee.

     The Agreement has been renewed and approved by the Board of Trustees as of
     July 1, 2004 with substantially the same terms. Under this current
     Agreement, Neuberger guarantees minimum revenue to the Fund and receives
     any revenue earned in excess of the guaranteed amount as a lending agency
     fee.

     At June 30, 2004, the Fund paid Neuberger $236 under the Agreement.

     Income earned on the securities loaned, if any, is reflected in the
     Statement of Operations under the caption Income from securities
     loaned-net.

9    Repurchase agreements: The Fund may enter into repurchase agreements with
     institutions that the Fund's investment manager has determined are
     creditworthy. Each repurchase agreement is recorded at cost. The Fund
     requires that the securities purchased in a repurchase agreement be
     transferred to the custodian in a manner sufficient to enable the Fund to
     assert a perfected security interest in those securities in the event of a
     default under the repurchase agreement. The Fund monitors, on a daily
     basis, the value of the securities transferred to ensure that their value,
     including accrued interest, is greater than amounts owed to the Fund under
     each such repurchase agreement.

10   Foreign taxes: Foreign taxes withheld represent amounts withheld by foreign
     tax authorities, net of refunds recoverable.

     Note B--Management Fees, Administration Fees, Distribution Arrangements,
     and Other Transactions With Affiliates:

     Fund shares are issued and redeemed in connection with investments in and
     payments under certain variable annuity contracts and variable life
     insurance policies issued through separate accounts of life insurance
     companies and are also offered directly to qualified pension and retirement
     plans.

     The Fund retains Management as its investment manager under a Management
     Agreement. For such investment management services, the Fund pays
     Management a fee at the annual rate of 0.55% of the first $250 million of
     the Fund's average daily net assets, 0.525% of the next $250 million, 0.50%
     of the next $250 million, 0.475% of the next $250 million, 0.45% of the
     next $500 million, 0.425% of the next $2.5 billion, and 0.40% of average
     daily net assets in excess of $4 billion.

     The Fund retains Management as its administrator under an Administration
     Agreement. The Fund pays Management an administration fee at the annual
     rate of 0.30% of its average daily net assets under this agreement.
     Additionally, Management retains State Street as its sub-administrator
     under a Sub-Administration Agreement. Management pays State Street a fee
     for all services received under the agreement.

     The Trustees of the Trust adopted a non-fee distribution plan for the Fund.

      NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST JUNE 30, 2004 (UNAUDITED)

     Management has contractually undertaken through December 31, 2007 to
     reimburse the Fund for its operating expenses (including the fees payable
     to Management, but excluding interest, taxes, brokerage commissions,
     extraordinary expenses, and transaction costs) ("Operating Expenses") which
     exceed, in the aggregate, 1.50% per annum of its average daily net assets
     (the "Expense Limitation"). Moreover, Management has voluntarily committed
     to reimburse certain expenses, as stated above, for an additional 0.20% per
     annum of the Fund's average daily net assets to maintain the Fund's
     Operating Expenses at 1.30%. Management may, at its sole discretion,
     terminate this additional voluntary reimbursement commitment without
     notice. For the six months ended June 30, 2004, such excess expenses
     amounted to $22,544. The Fund has agreed to repay Management through
     December 31, 2010 for its excess Operating Expenses previously reimbursed
     by Management, so long as its annual Operating Expenses during that period
     do not exceed its Expense Limitation, and the repayment is made within
     three years after the year in which Management issued the reimbursement.
     During the six months ended June 30, 2004, there was no reimbursement to
     Management. At June 30, 2004, the Fund has a contingent liability to
     Management under this agreement of $194,675, not repaid through June 30,
     2004.

     On October 31, 2003, Management and Neuberger, a member firm of the New
     York Stock Exchange and sub-adviser to the Fund, became indirect
     wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a
     publicly-owned holding company. Neuberger is retained by Management to
     furnish it with investment recommendations and research information without
     added cost to the Fund. Several individuals who are officers and/or
     Trustees of the Trust are also employees of Neuberger and/or Management.

     On July 1, 2003, the Fund entered into a commission recapture program,
     which enables it to pay some of its operational expenses by recouping a
     portion of the commissions it pays to a broker that is not a related party
     of the Fund. Expenses paid through this program may include costs of
     custodial, transfer agency or accounting services. For the six months ended
     June 30, 2004, the impact of this arrangement was a reduction of $566.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. The impact of this arrangement, reflected in the Statement of
     Operations under the caption Custodian fees, was a reduction of $16.

     Note C--Securities Transactions:

     During the six months ended June 30, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $5,384,632 and
     $1,315,362, respectively.

     During the six months ended June 30, 2004, brokerage commissions on
     securities transactions amounted to $10,079, of which Neuberger received
     $0, Lehman received $1,683, and other brokers received $8,396.

     Note E--Line of Credit:

     At June 30, 2004, the Fund was a participant in a single committed,
     unsecured $150,000,000 line of credit with State Street, to be used only
     for temporary or emergency purposes. Interes t is charged on borrowings
     under this agreement at the overnight Federal Funds Rate plus 0.50% per
     annum. A facility fee of 0.10% per annum of the available line of credit is
     charged, of which the Fund has agreed to pay its pro rata share, based on
     the ratio of its individual net assets to the net assets of all
     participants at the time the fee is due and payable. The fee is paid
     quarterly in arrears. No compensating balance is required. Other investment
     companies managed by Management also participate in this line of credit on
     the same terms. Because several investment companies participate, there is
     no assurance that the Fund will have access to the entire $150,000,000 at
     any particular time. The Fund had no loans outstanding pursuant to this
     line of credit at June 30, 2004, nor had the Fund utilized this line of
     credit at any time prior to that date.

     Note F--Unaudited Financial Information:

     The financial information included in this interim report is taken from the
     records of the Fund without audit by independent auditors. Annual reports
     contain audited financial statements.

+     The per share amounts and ratios which are shown reflect income and
      expenses, including the Fund's proportionate share of AMT Socially
      Responsive Investment's income and expenses through April 30, 2000 under
      the prior master/feeder fund structure.

++    Total return based on per share net asset value reflects the effects of
      changes in net asset value on the performance of the Fund during each
      fiscal period and assumes dividends and other distributions, if any, were
      reinvested. Results represent past performance and do not guarantee future
      results. Current returns may be lower or higher than the performance data
      quoted. Investment returns and principal may fluctuate and shares when
      redeemed may be worth more or less than original cost. Total return would
      have been lower if Management had not reimbursed certain expenses. The
      total return information shown does not reflect charges and other expenses
      that apply to the separate account or the related insurance policies, and
      the inclusion of these charges and other expenses would reduce the total
      return for all fiscal periods shown. Performance data current to the most
      recent month-end are available at www.nb.com.

#     The Fund is required to calculate an expense ratio without taking into
      consideration any expense reductions related to expense offset and
      commission recapture arrangements.

      investment manager not undertaken such action, the annualized ratios of
