Balanced Portfolio Managers' Commentary
- ---------------------------------------

U.S. stocks advanced in 2004, helping the AMT Balanced Portfolio's equity
investments to generate strong gains, while a mixed environment for bonds
limited the portfolio's fixed income investments to a modestly positive return.

For much of 2004, mixed economic signals, record high energy prices, and
uncertainty caused by a close Presidential election restrained stocks. Then,
the clouds over the market began to disperse. Favorable economic data indicated
that the economy had emerged from its summer doldrums, oil prices declined, and
a Republican election victory signaled an extension of current fiscal policies.
Stocks took off and closed 2004 with respectable gains, particularly in the
small- and mid-cap segments of the market.

For bond investors, conflicting economic signals made 2004 an unsteady year.
Doubts about the durability of the recovery kept prices stable early on, but
strong jobs reports in March and April precipitated a fixed income decline.
Later, however, rapidly rising oil prices helped keep the economy in check and,
even with a new monetary tightening campaign by the Federal Reserve, rates
stabilized before rising again during the fourth quarter.

In the equity portion of the Portfolio, our security selection within the
Information Technology (IT), Consumer Discretionary and Industrial sectors
provided the largest contributions to total returns for the year. In Consumer
Discretionary, our emphasis on casinos and gaming was particularly helpful,
while our focus on the services area of Financials also aided results, as did
our Energy holdings. Although, in aggregate, our sector allocation detracted
from the year's results, our overweight in the strong Telecom sector was
additive. On the downside, our stock selection within Health Care was a
negative, as generic pharmaceutical producers suffered from a lack of pricing
power, while our stock selection within Materials also hurt results.

For much of 2004, the fixed income portion of the Portfolio was defensively
postured, reflecting our recognition that low bond yields provided little
cushion for potential price declines should the economy accelerate. Our
relatively low duration helped shield investor capital as bonds retreated in
April and May, and generally enhanced returns for the full year. In the fourth
quarter, we enhanced portfolio yield by reducing our allocation to Treasuries
and increased our exposure to high-credit-quality alternatives including
asset-backed, corporate, and government agency securities. As the spread
between lower and higher rated securities narrowed, we upgraded the credit
quality of our corporate portfolio. We virtually eliminated our holdings in
mortgage-backed securities, since this group tends to underperform amidst
interest rate volatility.

Looking ahead, we believe that 2005 will be favorable for equity investors.
Although economic growth should slow from 2004's 4% pace, it is likely to
remain healthy, aided by ongoing corporate spending. After the strong results
of late 2004, we expect a short-term pullback, followed by further stock market
advances. As a result, we plan to position our equity portfolio more
aggressively than the indices and our competition, in stocks we believe have
more potential upside in a rising market. However, if stocks advance in early
2005, we currently anticipate rotating into more defensive areas, such as
Consumer Staples and Health Care. Currently, we are neutrally weighted in
Materials and Industrials, and underweight in Consumer Staples and Utilities.
Although Information Technology and Energy are both neutrally weighted, we
expect to be sellers of technology and buyers of energy over the longer term.

On the bond side, we believe that the Fed will continue to raise rates at a
"measured pace," with the Fed Funds rate probably reaching 3.5% by year-end
2005 (up from 2.25% in December and 1% in June). In addition, we are closely
watching factors that could influence inflation, including the

value of the dollar and the federal budget and current account deficits.
Overall, a healthy economy may continue to pressure bond prices, so we plan to
be cautious and maintain the Portfolio's duration at relatively low levels. And
we are likely to continue attempting to enhance portfolio yield by diversifying
away from Treasuries to other high quality, higher yielding sectors.

              1. 9.31%, (2.73%), and 7.50% were the average annual total
                 returns for the 1-, 5- and 10-year periods ended December 31,
                 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. The performance information does
                 not reflect fees and expenses of the insurance companies.

              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 26% of the total market
                 capitalization of the Russell 1000 Index (which, in turn,
                 consists of the 1,000 largest U.S. companies, based on the
                 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.

                 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.

Information About Your Fund's Expenses
- --------------------------------------

This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:


                                                  

                                Actual Expenses:    The first section
                                                    of the table provides
                                                    information about actual
                                                    account values and actual
                                                    expenses in dollars. You may
                                                    use the information in this
                                                    line, together with the
                                                    amount you invested, to
                                                    estimate the expenses you
                                                    paid over the period.

      Hypothetical Example for Comparison Purposes: The second section of the
                                                    table provides information
                                                    about hypothetical account
                                                    values and hypothetical
                                                    expenses based on the Fund's
                                                    actual expense ratio and an

Notes to Schedule of Investments Balanced Portfolio
- ---------------------------------------------------

+       Investments in equity securities by Neuberger Berman Advisers
        Management Trust Balanced Portfolio (the "Fund") are valued at the
        latest sale 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 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 and
        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 noon, 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. When changes in
        the value of a certain index suggest that the closing prices on the
        foreign exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income
        tax purposes was $71,298,971. Gross unrealized appreciation of
        investments was $14,170,855 and gross unrealized depreciation of
        investments was $689,810, resulting in net unrealized appreciation of
        $13,481,045, based on cost for U.S. Federal income tax purposes.

*       Non-income producing security.

**      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 and are deemed liquid. At December 31, 2004, these securities
        amounted to $533,724 or 0.7% of net assets.

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

@       Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
        Neuberger Berman Management Inc. (see Notes A & F of Notes to
        Financial Statements) and may be considered an affiliate since it has
        the same officers, Board members, and investment manager as the Fund
        and because, at times, the Fund may own 5% or more of the outstanding
        voting securities of Prime Money.

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 eleven
          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 (the "Board") 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 U.S.
          generally accepted accounting principles 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 noon, 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, if any, are recorded on the basis of
          identified cost and stated separately in the Statement of Operations.
          Included in net realized gain (loss) on investments are proceeds from
          the settlements of class action litigation in which the Fund
          participated as a plaintiff. The amount of such proceeds for the year
          ended December 31, 2004 was $21,154.

     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    Income tax information: 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 requirements of Subchapter M of the Internal Revenue Code
          applicable to regulated investment companies and to distribute
          substantially all of its earnings to its shareholders. Therefore, no
          Federal income or excise tax provision is required.

          Income dividends and capital gain distributions are determined in
          accordance with income tax regulations, which may differ from
          generally accepted accounting principles. These differences are
          primarily due to differing treatments of income and gains on various
          investment securities held by the Fund, timing differences and
          differing characterization of distributions made by the Fund as a
          whole. The Fund may also utilize earnings and profits distributed to
          shareholders on redemption of shares as a part of the dividends paid
          deduction for income tax purposes.

          As determined on December 31, 2004, permanent differences resulting
          primarily from different book and tax accounting for foreign currency
          gains and losses, paydown gains and losses, amortization of bond
          premium, and mortgage dollar rolls, were reclassified at year end.
          These reclassifications had no effect on net income, net assets or net
          assets per share of the Fund.

          The tax character of distributions paid during the years ended
          December 31, 2004 and December 31, 2003 were as follows:



Distributions Paid From:
             Ordinary Income                    Total
            2004            2003          2004            2003
                                          
        $989,988      $1,410,014      $989,988      $1,410,014


          As of December 31, 2004, the components of distributable earnings
          (accumulated losses) on a U.S. Federal income tax basis were as
          follows:



                          Unrealized              Loss
    Undistributed       Appreciation     Carryforwards
  Ordinary Income     (Depreciation)     and Deferrals            Total
                                               
         $711,015        $13,482,384     $(40,201,704)    $(26,008,305)


          The difference between book basis and tax basis distributable earnings
          is attributable primarily to timing differences of wash sales, mark to
          market on certain forward foreign currency contracts, and amortization
          of bond premium. 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. As determined at December
          31, 2004, the Fund had unused capital loss carryforwards available for
          Federal income tax purposes to offset net realized capital gains, if
          any, as follows:

                                       16


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004



                                          Expiring in
                                                 2009             2010
                                                       
                                          $26,467,694      $13,734,010


          During the year ended December 31, 2004, the Fund utilized capital
          loss carryforwards of $2,378,120.

        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.

        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 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.

       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

                                       17


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

          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 year ended December 31, 2004, the Fund entered into various
          financial futures contracts. At December 31, 2004, there were no open
          positions.

       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 Board, 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 ("Quality Fund"), which is managed by State Street
          Bank and Trust Company ("State Street") pursuant to guidelines
          approved by the Trust's investment manager. Neuberger guaranteed a
          certain amount of 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 as of July 1,
          2004 with substantially the same terms. Under this current Agreement,
          Neuberger guarantees a certain amount of revenue to the Fund and
          receives any revenue earned in excess of the guaranteed amount as a
          lending agency fee. For the year ended December 31, 2004, Neuberger
          did not receive any revenue 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-affiliated issuer.

          In February of 2005, it is likely that the Fund will change the
          collateral investment vehicle from the Quality Fund, managed by State
          Street, to a fund managed by Lincoln Capital, an affiliate, as
          approved by the Board.

       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") and the
          Neuberger Berman Prime Money Fund ("Prime Money"), affiliated funds,
          which are managed by Management and have the same Board members as the
          Fund. The Cash Fund and Prime Money each seeks to provide as high a
          level of current

                                       18


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

          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 or Prime Money, Management waives a portion of its
          management fee equal to the management fee it receives from the Cash
          Fund or Prime Money on those assets. For the year ended December 31,
          2004, management fees waived amounted to $296 and $6 for the Cash Fund
          and Prime Money, respectively. For the year ended December 31, 2004,
          income earned on the investments of the Cash Fund and Prime Money
          amounted to $2,779 and $133, respectively, and is reflected in the
          Statement of Operations under the caption Income from investments in
          affiliated issuers.

       14 Dollar rolls: The Fund may enter into dollar roll transactions with
          respect to mortgage-backed securities. In a dollar roll transaction,
          the Fund sells securities for delivery in the current month and
          simultaneously agrees to repurchase substantially similar (i.e., same
          type and coupon) securities on a specified future date from the same
          party. During the period before the repurchase, the Fund foregoes
          principal and interest payments on the securities. The Fund is
          compensated by the difference between the current sales price and the
          forward price for the future purchase (often referred to as the
          "drop"), as well as by the interest earned on the cash proceeds of the
          initial sale. Dollar rolls may increase fluctuations in the Fund's net
          asset value and may be viewed as a form of leverage. There is a risk
          that the counter party will be unable or unwilling to complete the
          transaction as scheduled, which may result in losses to the Fund.

       15 Indemnifications: Like many other companies, the Trust's
          organizational documents provide that its officers and trustees are
          indemnified against certain liabilities arising out of the performance
          of their duties to the Trust. In addition, both in some of its
          principal service contracts and in the normal course of its business,
          the Trust enters into contracts that provide indemnifications to other
          parties for certain types of losses or liabilities. The Trust's
          maximum exposure under these arrangements is unknown as this could
          involve future claims against the Trust.

          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 this
          agreement.

                                       19

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

The Board adopted a non-fee distribution plan for the Fund.

Management has contractually undertaken through December 31, 2008 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 the Fund's average daily net assets (the "Expense Limitation"). For the year
ended December 31, 2004, no reimbursement to the Fund was required. The Fund
has agreed to repay Management through December 31, 2011 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 year ended December 31, 2004, there was no
reimbursement to Management under this agreement. At December 31, 2004, the
Fund has no contingent liability to Management under this 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 year ended December 31, 2004, the impact
of this arrangement was a reduction of expenses of $7,363.

The Fund has an expense offset arrangement in connection with its custodian
contract. For the year ended December 31, 2004, the impact of this arrangement
was a reduction of expenses of $176.

Note E--Line of Credit:

At December 31, 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 all or any
part of the $150,000,000 at any particular time. The Fund had no loans
outstanding pursuant to this line of credit at December 31, 2004, nor had the
Fund utilized this line of credit at any time prior to that date.

          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

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Balanced Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Balanced Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as
of December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian and brokers or other
appropriate auditing procedures where replies from brokers were not received.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Balanced Portfolio of Neuberger Berman Advisers Management Trust at December
31, 2004, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended, and its
financial highlights for each of the five years in the period then ended, in
conformity with U.S. generally accepted accounting principles.

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

In mid-August, small-cap stocks pulled out of a summer tailspin and rallied for
the rest of 2004. For the year, the small-cap Russell 2000 Index once again
significantly outperformed the large-cap S&P 500.2 The Neuberger Berman AMT
Fasciano Portfolio finished behind its Russell 2000 benchmark, largely due to
underperformance in the Consumer Discretionary and Health Care sectors.

In 2004, our Industrial investments had a strongly positive impact on our
absolute returns. Trucking logistics company Landstar System, pump and valve
manufacturer IDEX Corp., maintenance and repair products distributor MSC
Industrial Direct, and uniform rental company G&K Services were all stellar
performers. Our Information Technology (IT) stocks helped results relative to
the benchmark. Scansource, a distributor of bar code printers, and Plantronics,
a wireless headset manufacturer, both provided gains compared to a small loss
for comparable stocks in the Russell 2000. Although they underperformed, our
Energy holdings provided solid absolute returns. Carbo Ceramics, a manufacturer
of ceramic material used in oil recovery, and Offshore Logistics, whose
helicopters transport workers and supplies to offshore drilling rigs, were
notably strong.

Our Consumer Discretionary investments proved disappointing in 2004, with radio
and television broadcaster Emmis Communications and retailer Sharper Image both
making our "bottom ten" list. For Emmis, weakness in auto ad sales hurt
profits, while listener ratings and cash flows were under pressure at its
alternative rock station in Chicago. Also, excitement about satellite radio has
raised concerns about traditional radio outlets. However, we believe that Emmis
has the "right stuff" to overcome today's challenges. It has kept a tight rein
on expenses and has long been successful at buying and improving poorly
performing properties. With a new radio acquisition, it has an opportunity to
increase sales and realize cost savings. Looking ahead, we believe that higher
corporate confidence may raise ad spending above expectations, and we do not
believe that pay satellite radio will have much impact on free radio stations.
As a result, we continue to hold Emmis Communications and believe it will be a
rewarding long-term investment.

In contrast, we have thrown in the towel on Sharper Image. We bought the
company because it had solid footholds in mailorder, Internet, and traditional
store retailing. Plus, the Sharper Image brand name generated good profit
margins. However, the market for highly discretionary consumer electronics
appears to be weakening, which is restraining the company's sales and eroding
its pricing power.

Among our Health Care stocks, we believe that KV Pharmaceuticals and ICU
Medical--both disappointments in 2004--are currently getting back on track.
KV's stock fell when it changed auditors, alarming shareholders who were
already concerned about a lull in new product releases. However, KV's change of
auditors turned out to be a non-event and the company has since introduced a
promising new product named Clindesse. With the stock well off its low,
investors are beginning to recognize the company's solid progress. ICU Medical,
known for excellent IV-related products and distribution, lowered earnings
guidance when its largest customer decided to work down inventories before
placing new orders. With that one-time event behind it, we anticipate that the
company's sales and earnings will rebound.

Another stock in the group, D&K Healthcare, seems far less promising. With
losses this year, we sold the stock because of lingering profitability issues
and concerns about fierce competition in the wholesale drug distribution
business.

As our longer-term shareholders know, we are not economists or market
forecasters and find it more

productive to focus on bottom-up, company fundamentals. That said, the
consensus outlook for 2005 is for moderate economic growth and relatively low
inflation, which is generally good for equities. Small-caps have had a big run
over the last six years and some observers believe that this cannot continue,
suggesting that perhaps large-caps present better value. As you would expect,
we are always excited about small-cap stocks. We view the group as fertile
ground for new ideas and will remain diligent in finding value among companies
that meet our quality and growth requirements.

Sincerely,

                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 $128 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

Information About Your Fund's Expenses
- --------------------------------------


This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:


                                           
                             Actual Expenses: The first section of the table provides information about actual account
                                              values and actual expenses in dollars. You may use the information in this line,
                                              together with the amount you invested, to estimate the expenses you paid over the
                                              period.

Hypothetical Example for Comparison Purposes: The second section of the table provides information about hypothetical account values
                                              and hypothetical expenses based on the Fund's actual expense ratio and an assumed
                                              rate of return at 5% per year before expenses. This return is not the Fund's actual

                                              To do so, compare this 5% hypothetical example with the 5% hypothetical examples
                                              that appear in the shareholder reports of other funds.

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


+  Investments in equity securities by Neuberger Berman Advisers Management
   Trust Fasciano Portfolio (the "Fund") are valued at the latest sale 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 and 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 noon, 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. When changes in the value of a certain index suggest
   that the closing prices on the foreign exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income tax
   purposes was $13,813,281. Gross unrealized appreciation of investments was
   $2,045,432 and gross unrealized depreciation of investments was $39,585,
   resulting in net unrealized appreciation of $2,005,847, based on cost for
   U.S. Federal income tax purposes.

*  Non-income producing security.

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

@  Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
   Neuberger Berman Management Inc. (see Notes A & F of Notes to Financial
   Statements) and may be considered an affiliate since it has the same
   officers, Board members, and investment manager as the Fund and because, at
   times, the Fund may own 5% or more of the outstanding voting securities of
   Prime Money.

++ The N&B Securities Lending Quality Fund, LLC ("Quality Fund") is an
   investment vehicle established by the Fund's custodian to invest cash the
   Fund receives as collateral for securities loans. The Fund's shares in the
   Quality Fund are non-voting. However, because all shares of the Quality Fund
   are held by funds in the related investment management complex, the Quality
   Fund may be considered an affiliate of the Fund (see Notes A & F of Notes to
   Financial Statements).

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004


Notes to Financial Statements Fasciano Portfolio
- ------------------------------------------------

     Note A--Summary of Significant Accounting Policies:


 1   General: Fasciano 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 eleven 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 S
     shares. The Board of Trustees of the Trust (the "Board") 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 U.S. generally
     accepted accounting principles 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 noon, 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, if any, are recorded on the
     basis of identified cost and stated separately in the Statement of
     Operations.

 5   Income tax information: 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
     requirements of Subchapter M of the Internal Revenue Code applicable to
     regulated investment companies and to distribute substantially all of its
     earnings to its shareholders. Therefore, no Federal income or excise tax
     provision is required.


                                       11


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


     Income dividends and capital gain distributions are determined in
     accordance with income tax regulations, which may differ from generally
     accepted accounting principles. These differences are primarily due to
     differing treatments of income and gains on various investment securities
     held by the Fund, timing differences and differing characterization of
     distributions made by the Fund as a whole. The Fund may also utilize
     earnings and profits distributed to shareholders on redemption of shares as
     a part of the dividends paid deduction for income tax purposes.

     As determined on December 31, 2004, permanent differences resulting
     primarily from different book and tax accounting for net operating losses
     were reclassified at year end. These reclassifications had no effect on net
     income, net assets or net assets per share of the Fund.

     The tax character of distributions paid during the years ended December 31,
     2004 and December 31, 2003 were as follows:



     Distributions Paid From:


           Ordinary Income           Long-Term Capital Gain                   Total
       2004           2003                2004         2003             2004          2003
                                                                     
     $4,205         $2,283             $31,902        $  --          $36,107        $2,283


     As of December 31, 2004, the components of distributable earnings
     (accumulated losses) on a U.S. Federal income tax basis were as follows:



                         Undistributed         Unrealized              Loss
       Undistributed         Long-Term       Appreciation     Carryforwards
     Ordinary Income              Gain     (Depreciation)     and Deferrals          Total
                                                                    
             $44,290           $40,383         $2,005,847          $(2,608)     $2,087,912


     The difference between book basis and tax basis distributable earnings is
     attributable primarily to timing differences of wash sales and post-October
     losses.

     Under current tax law, certain net 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, 2004, the Fund elected to defer $2,608 of net
     capital losses arising between November 1, 2004 and December 31, 2004.

     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.

 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.

 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


                                       12



                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004


     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 Board, 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
     ("Quality Fund"), which is managed by State Street Bank and Trust Company
     ("State Street") pursuant to guidelines approved by the Trust's investment
     manager. Neuberger guaranteed a certain amount of 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 as of July 1, 2004
     with substantially the same terms. Under this current Agreement, Neuberger
     guarantees a certain amount of revenue to the Fund and receives any revenue
     earned in excess of the guaranteed amount as a lending agency fee. For the
     year ended December 31, 2004, Neuberger received $32 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-affiliated issuer.

     In February of 2005, it is likely that the Fund will change the collateral
     investment vehicle from the Quality Fund, managed by State Street, to a
     fund managed by Lincoln Capital, an affiliate, as approved by the Board.

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") and the Neuberger Berman Prime Money Fund ("Prime
     Money"), affiliated funds, which are managed by Management and have the
     same Board members as the Fund. The Cash Fund and Prime Money each 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 or Prime Money, Management waives a
     portion of its management fee equal to the management fee it receives from
     the Cash Fund or Prime Money on those assets. For the year ended December
     31, 2004, management fees waived amounted to $1,094 and $22 for the Cash
     Fund and Prime Money, respectively. For the year ended December 31, 2004,
     income earned on the investments of the Cash Fund and Prime Money amounted
     to $12,617 and $529, respectively, and is reflected in the Statement of
     Operations under the caption Income from investments in affiliated issuers.


                                       13

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


11   Indemnifications: Like many other companies, the Trust's organizational
     documents provide that its officers and trustees are indemnified against
     certain liabilities arising out of the performance of their duties to the
     Trust. In addition, both in some of its principal service contracts and in
     the normal course of its business, the Trust enters into contracts that
     provide indemnifications to other parties for certain types of losses or
     liabilities. The Trust's maximum exposure under these arrangements is
     unknown as this could involve future claims against the Trust.

     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 $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 this agreement.

     Management acts as agent in arranging for the sale of Fund shares without
     commission and bears advertising and promotion expenses. The Board has
     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 the Fund's
     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, 2008 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


                                       14



                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004


     aggregate, 1.40% per annum of the Fund's average daily net assets (the
     "Expense Limitation"). For the year ended December 31, 2004, such excess
     expenses amounted to $108,225. The Fund has agreed to repay Management
     through December 31, 2011 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 year ended December 31, 2004, there was no
     reimbursement to Management under this agreement. At December 31, 2004,
     contingent liabilities to Management under this agreement were as follows:



                   Expiring in
                          2005            2006             2007            Total
                                                               
                       $44,573         $92,031         $108,225         $244,829


     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 year ended
     December 31, 2004, the impact of this arrangement was a reduction of
     expenses of $890.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. For the year ended December 31, 2004, the impact of this
     arrangement was a reduction of expenses of $7.


     Note C--Securities Transactions:

     During the year ended December 31, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $8,267,751 and $853,577,
     respectively.

     During the year ended December 31, 2004, brokerage commissions on
     securities transactions amounted to $11,401, of which Neuberger received
     $10, Lehman received $2,306, and other brokers received $9,085.

     Note E--Line of Credit:

     At December 31, 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 all or any part of the
     $150,000,000 at any particular time. The Fund had no loans outstanding
     pursuant to this line of credit at December 31, 2004, nor had the Fund
     utilized this line of credit at any time prior to that date.

++    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. 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

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------


To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Fasciano Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Fasciano Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as
of December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Fasciano Portfolio of Neuberger Berman Advisers Management Trust at December
31, 2004, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended and its
financial highlights for the periods indicated therein, in conformity with U.S.
generally accepted accounting principles.

Focus Portfolio Managers' Commentary
- ------------------------------------

The Neuberger Berman AMT Focus Portfolio generated a positive return for 2004,
but trailed the S&P 500 Index and the Russell 1000 Value Index.(2) Although we
are pleased that our investors gained ground during the reporting period, we
are not pleased about lagging the unmanaged benchmarks.

During the year, we were helped by our positions in truck and construction
equipment seller Rush Enterprises, marketing services provider Vertrue and
credit card companies Capital One and Providian. However, we were hindered by
an overweight position in Information Technology and the fact that two of our
bigger positions in the area--Amkor and International Rectifier--
declined for the period. In terms of relative performance, our lack of Energy
holdings was a negative.

In considering where we stand today, it is worth taking a moment to review our
investment discipline. Basically, we want to own stocks that sell at a discount
to the market (as measured by their price/earnings ratio) but offer superior
growth prospects. Since such stocks are not that plentiful, this strategy
dovetails nicely with our concentrated portfolio approach. We believe that our
holdings reflect our strategy: At year-end, the p/e on the overall portfolio
(based on analysts' consensus earnings estimates for 2005) was 14.3--a 13%
discount to the S&P 500--while our expected long term earnings growth rate was
16.9%, or 42% more than that of the S&P's. (These numbers come from an
independent third party, and we consider them to be objective.)*

The reason for adhering to this discipline is, quite simply, that it makes
sense that buying a superior earnings stream at a discounted price should
generate superior returns over time. Looking at our results in a slightly
longer context (2003-2004) seems to bear this out, as the Fund provided a
return that more than doubled that of the S&P 500.

Employing this discipline had led us to an overweight position in Financials,
since these stocks typically sell at a discount to the market, despite
long-term earnings records that have equaled or surpassed the market averages.
Thus, we still own our credit card stocks, as well as Citigroup, JP Morgan,
Merrill Lynch and Morgan Stanley. We like these companies, their managements,
their prospects and their valuations.

We also maintain a substantial position in Information Technology, and here too
our experience in 2004 is illustrative of our thought process. We have an
investment thesis for every stock we own, but if we come to believe that the
thesis is no longer valid we will eliminate the position. For example, as 2004
progressed, it became apparent to us that Amkor was not executing as
anticipated and was in fact losing market share. While realizing a loss was
painful, we do not retain positions in which our original expectations are not
being met. Conversely, all our expectations for our investment in International
Rectifier were either met or exceeded, yet the stock declined. Since the
stock's retreat coincided with an improvement in its fundamentals, we increased
the position.

Focus Portfolio Managers' Commentary cont'd
- -------------------------------------------

In sum, what we do is fairly predictable since we consistently adhere to our
long-held investment strategy. While the current investment backdrop has more
uncertainties than usual--terrorism, the high budget and balance-of-trade
deficits, etc.--we have been able to find stocks that we think have the
superior characteristics we require.

Sincerely,

                                /s/ Kent Simons

             1. 6.21% and 39.49% were the average annual total returns for the
                1-year and since inception (08/08/02) periods ended December
                31, 2004. This performance was attained at a time that the
                asset size of the Portfolio was small. The Portfolio's total
                net assets as of December 31, 2004 was $1,185,741. 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. The
                performance information does not reflect fees and expenses of
                the insurance companies.

             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 the 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 many 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.

                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.

The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:


                                             
                               Actual Expenses: The first section of the table provides information about actual account
                                                values and actual expenses in dollars. You may use the information in this line,
                                                together with the amount you invested, to estimate the expenses you paid over
                                                the period.


  Hypothetical Example for Comparison Purposes: The second section of the table provides information about hypothetical
                                                account values and hypothetical expenses based on the Fund's actual expense
                                                ratio and an assumed rate of return at 5% per year before expenses. This
                                                return is not the Fund's actual return. The hypothetical account values and
                                                expenses may not be used to estimate the actual ending account balance or
                                                expenses you paid for the period. You may use this information to compare
                                                the ongoing costs of investing in this Fund versus other funds. To do so,
                                                compare this 5% hypothetical example with the 5% hypothetical examples that
                                                appear in the shareholder reports of other funds.

Notes to Schedule of Investments Focus Portfolio
- ------------------------------------------------

+    Investments in equity securities by Neuberger Berman Advisers
     Management Trust Focus Portfolio (the "Fund") are valued at the latest
     sale 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 and
     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 noon, 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. When changes in
     the value of a certain index suggest that the closing prices on the
     foreign exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income
     tax purposes was $868,505. Gross unrealized appreciation of
     investments was $362,359 and gross unrealized depreciation of
     investments was $11,338, resulting in net unrealized appreciation of
     $351,021, based on cost for U.S. Federal income tax purposes.

*    Non-income producing security.

@    Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
     Neuberger Berman Management Inc. (see Notes A & F of Notes to
     Financial Statements) and may be considered an affiliate since it has
     the same officers, Board members, and investment manager as the Fund
     and because, at times, the Fund may own 5% or more of the outstanding
     voting securities of Prime Money.

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 eleven
          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 (the "Board") 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 U.S.
          generally accepted accounting principles 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 noon, 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, if any, are recorded on the basis of identified cost and
          stated separately in the Statement of Operations.

     5    Income tax information: 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 requirements of Subchapter M of the Internal Revenue Code
          applicable to regulated investment companies and to distribute
          substantially all of its earnings to its shareholders. Therefore, no
          Federal income or excise tax provision is required.


                                       10


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

          Income dividends and capital gain distributions are determined in
          accordance with income tax regulations, which may differ from
          generally accepted accounting principles. These differences are
          primarily due to differing treatments of income and gains on various
          investment securities held by the Fund, timing differences and
          differing characterization of distributions made by the Fund as a
          whole. The Fund may also utilize earnings and profits distributed to
          shareholders on redemption of shares as a part of the dividends paid
          deduction for income tax purposes.

          As determined on December 31, 2004, permanent differences resulting
          primarily from different book and tax accounting for net operating
          losses were reclassified at year end. These reclassifications had no
          effect on net income, net assets or net assets per share of the Fund.

          The tax character of distributions paid during the years ended
          December 31, 2004 and December 31, 2003 were as follows:



Distributions Paid From:

               Ordinary Income           Long Term Capital Gain                Total
              2004        2003             2004         2003               2004        2003
                                                                      
          $113,929      $7,067           $6,620          $ -           $120,549      $7,067


          As of December 31, 2004, the components of distributable earnings
          (accumulated losses) on a U.S. Federal income tax basis were as
          follows:



                                                                 Loss
  Undistributed     Undistributed         Unrealized    Carryforwards
       Ordinary         Long-Term       Appreciation              and
         Income              Gain     (Depreciation)        Deferrals         Total
                                                               
            $ -           $19,811           $351,021              $ -      $370,832


          The difference between book basis and tax basis distributable earnings
          is attributable primarily to timing differences of wash sales.

          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.

     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.

     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 Focus 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.

     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 Board, 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 ("Quality Fund"), which is managed by State Street
          Bank and Trust Company ("State Street") pursuant to guidelines
          approved by the Trust's investment manager. Neuberger guaranteed a
          certain amount of 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 as of July 1,
          2004 with substantially the same terms. Under this current Agreement,
          Neuberger guarantees a certain amount of revenue to the Fund and
          receives any revenue earned in excess of the guaranteed amount as a
          lending agency fee. For the year ended December 31, 2004, Neuberger
          did not receive any revenue 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-affiliated issuer.

          In February of 2005, it is likely that the Fund will change the
          collateral investment vehicle from the Quality Fund, managed by State
          Street, to a fund managed by Lincoln Capital, an affiliate, as
          approved by the Board.

     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") and the Neuberger Berman
          Prime Money Fund ("Prime Money"), affiliated funds, which are managed
          by Management and have the same Board members as the Fund. The Cash
          Fund and Prime Money each 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 or Prime Money, Management waives a portion of its
          management fee equal to the management fee it receives from the Cash
          Fund or Prime Money on those assets. For the year ended December 31,
          2004, such waived fees amounted to $53 and $0 for the Cash Fund and
          Prime Money, respectively. For the year ended December 31, 2004,
          income earned on the investments of the Cash Fund and Prime Money
          amounted to $524 and $3, respectively, and is reflected in the
          Statement of Operations under the caption Income from investments in
          affiliated issuers.

     11   Indemnifications: Like many other companies, the Trust's
          organizational documents provide that its officers and trustees are
          indemnified against certain liabilities arising out of the performance
          of their duties to the Trust. In addition, both in some of its
          principal service contracts and in the normal course

          of its business, the Trust enters into contracts that provide
          indemnifications to other parties for certain types of losses or
          liabilities. The Trust's maximum exposure under these arrangements is
          unknown as this could involve future claims against the Trust.

          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 this
          agreement.

          Management acts as agent in arranging for the sale of Fund shares
          without commission and bears advertising and promotion expenses. The
          Board has 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 the Fund's 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, 2008 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 the Fund's average daily net assets (the "Expense Limitation"). For
          the year ended December 31, 2004, such excess expenses amounted to
          $80,604. The Fund has agreed to repay Management through December 31,
          2011 for its excess Operating Expenses previously reimbursed

                                       13

          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 year ended December 31, 2004, there was no
          reimbursement to Management under this agreement. At December 31,
          2004, contingent liabilities to Management under this agreement were
          as follows:



                      Expiring in
                             2005        2006        2007       Total

          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
          year ended December 31, 2004, the impact of this arrangement was a
          reduction of expenses of $75.

          The Fund has an expense offset arrangement in connection with its
          custodian contract. For the year ended December 31, 2004, the impact
          of this arrangement was a reduction of expenses of $1.

          Note C--Securities Transactions:

          During the year ended December 31, 2004, there were purchase and sale
          transactions (excluding short-term securities) of $426,810 and
          $376,587, respectively.

          During the year ended December 31, 2004, brokerage commissions on
          securities transactions amounted to $1,520, of which Neuberger
          received $109, Lehman received $184, and other brokers received
          $1,227.

          Note D--Fund Share Transactions:

          Share activity for the years ended December 31, 2004 and December 31,
          2003 was as follows:

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

          Note E--Line of Credit:

          At December 31, 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 all or any part of the $150,000,000 at
          any particular time. The Fund had no loans outstanding pursuant to
          this line of credit at December 31, 2004, nor had the Fund utilized
          this line of credit at any time prior to that date.

++    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

      reinvested. Results represent past performance and do not guarantee future
      results. Current returns may be lower or higher than the performance data

      expenses. The total return information shown does not reflect charges and
      other expenses that apply to the separate account or the related insurance

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Focus Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Focus Portfolio, one of the series constituting
the Neuberger Berman Advisers Management Trust (the "Trust"), as of December
31, 2004, and the related statement of operations for the year then ended, the
statement of changes in net assets for each of the two years in the period then
ended and the financial highlights for the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Focus
Portfolio of Neuberger Berman Advisers Management Trust at December 31, 2004,
the results of its operations for the year then ended, the changes in its net
assets for each of the years in the period then ended and its financial
highlights for each of the periods indicated herein, in conformity with U.S.
generally accepted accounting principles.

Growth Portfolio Managers' Commentary
- -------------------------------------

The Neuberger Berman AMT Growth Portfolio posted positive returns for calendar
year 2004, outperforming its benchmark, the Russell Midcap Growth Index.(2)

Our security selection within the Information Technology (IT), Consumer
Discretionary and Industrial sectors provided the largest contributions to
total returns for the year. Within IT, names that did well included Alliance
Data Systems (ADS) and Apple Computer Inc (AAPL). In Consumer Discretionary,
our emphasis on casinos and gaming was particularly additive to performance.
Industrial stocks that outperformed included JB Hunt Transport Services (JBHT)
and Corporate Executive Board (EXBD). Our emphasis on the services area of
Financials helped results, with strong performers including First Marblehead
(FMD) and Capitalsource Inc (CSE). Energy was again additive, as companies like
XTO Energy (XTO), with the ability to increase reserves or production of oil
and gas, generated strong returns. Although, in aggregate, our sector
allocation detracted from the year's results, our overweight in Telecom, one of
the strongest performing sectors, was additive.

On the downside, our stock selection within Health Care had the most negative
impact on relative portfolio performance. The environment for generic
pharmaceuticals was particularly weak given the lack of pricing power in the
industry. Our stock selection in Materials, representing 2-3% of the benchmark,
also hurt returns.

Looking ahead to 2005, we believe that economic headwinds should act to slow
economic growth from the 4% pace achieved in 2004. Tighter fiscal and monetary
policies, slowing Asian economies, the need for U.S. consumers to increase
savings, higher energy costs and a normal mid-cycle deceleration all may come
into play. This is not to say that we believe the economy is in much danger of
decline. "Real" (after inflation) interest rates remain historically low, while
the Fed remains on a "measured pace" to raise rates. In addition, corporate
spreads and the yield curve indicate continued economic expansion, and
corporate hiring and investment plans appear intact.

As a result, we believe that 2005 should prove favorable for equity investors.
Although, in our opinion, keeping inflation in check is a key to further equity
market advancement, the equity market's technicals appear healthy in the near
term. After the strong late-year market gains, sparked by the Presidential
election results and drop in crude oil prices, we expect stocks to pull back in
the weeks ahead, before moving higher again. Because we believe that the market
remains in a rally phase, we want to be positioned more aggressively than the
indices and our competition, in stocks we believe have more potential upside in
a rising market.

If the market advances in the first part of 2005, however, we currently
anticipate making rotational changes in the portfolio into more defensive
areas, such as Consumer Staples and Health Care. Currently, we are neutrally
weighted in Materials and Industrials, and underweight in Consumer Staples and
Utilities. Although the Information Technology and Energy sectors are both
neutrally weighted in the portfolio, we expect to be sellers of technology and
buyers of energy over the longer term.

Sincerely,


        /s/ Jon D. Brorson

     1.   16.60%, (8.29%) and 7.66% were the average annual total returns for
          the 1-, 5- and 10-year periods ended December 31, 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. The performance information does not reflect fees
          and expenses of the insurance companies.

     2.   The Russell Midcap[RegTM] Growth Index measures the performance of
          those Russell Midcap[RegTM] Index companies with higher pric%e-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 26% 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.

          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.

Information About Your Fund's Expenses
- --------------------------------------

This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:


                                                  
                                 Actual Expenses:   The first section
                                                    of the table provides
                                                    information about actual
                                                    account values and actual
                                                    expenses in dollars. You may
                                                    use the information in this
                                                    line, together with the
                                                    amount you invested, to
                                                    estimate the expenses you
                                                    paid over the period.

    Hypothetical Example for Comparison Purposes:   The second section of the
                                                    table provides information
                                                    about hypothetical account
                                                    values and hypothetical
                                                    expenses based on the Fund's
                                                    actual expense ratio and an
                                                    assumed rate of return at 5%
                                                    per year before expenses.
                                                    This return is not the
                                                    Fund's actual return. The
                                                    hypothetical account values
                                                    and expenses may not be used
                                                    to estimate the actual
                                                    ending account balance or
                                                    expenses you paid for the
                                                    period. You may use this
                                                    information to compare the
                                                    ongoing costs of investing
                                                    in this Fund versus other
                                                    funds. To do so, compare
                                                    this 5% hypothetical example
                                                    with the 5% hypothetical
                                                    examples that appear in the
                                                    shareholder reports of other
                                                    funds.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

Notes to Schedule of Investments Growth Portfolio
- -------------------------------------------------

+    Investments in equity securities by Neuberger Berman Advisers Management
     Trust Growth Portfolio (the "Fund") are valued at the latest sale 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 and 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 noon, 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. When changes in the
     value of a certain index suggest that the closing prices on the foreign
     exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income tax
     purposes was $187,982,254. Gross unrealized appreciation of investments was
     $62,506,346 and gross unrealized depreciation of investments was $948,406,
     resulting in net unrealized appreciation of $61,557,940, based on cost for
     U.S. Federal income tax purposes.

*    Non-income producing security.

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

@    Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
     Neuberger Berman Management Inc. (see Notes A & F of Notes to Financial
     Statements) and may be considered an affiliate since it has the same
     officers, Board members, and investment manager as the Fund and because, at
     times, the Fund may own 5% or more of the outstanding voting securities of
     Prime Money.

++   The N&B Securities Lending Quality Fund, LLC ("Quality Fund") is an
     investment vehicle established by the Fund's custodian to invest cash the
     Fund receives as collateral for securities loans. The Fund's shares in the
     Quality Fund are non-voting. However, because all shares of the Quality
     Fund are held by funds in the related investment management complex, the
     Quality Fund may be considered an affiliate of the Fund (see Notes A & F of
     Notes to Financial Statements).

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 eleven
          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 (the "Board") 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 U.S.
          generally accepted accounting principles 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 noon, 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, if any, 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 year
          ended December 31, 2004 was $108,002.

     5    Income tax information: 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 requirements of Subchapter M of the Internal Revenue Code
          applicable to regulated

                                       11

          investment companies and to distribute substantially all of its
          earnings to its shareholders. Therefore, no Federal income or excise
          tax provision is required.

          Income dividends and capital gain distributions are determined in
          accordance with income tax regulations, which may differ from
          generally accepted accounting principles. These differences are
          primarily due to differing treatments of income and gains on various
          investment securities held by the Fund, timing differences and
          differing characterization of distributions made by the Fund as a
          whole. The Fund may also utilize earnings and profits distributed to
          shareholders on redemption of shares as a part of the dividends paid
          deduction for income tax purposes.

          As determined on December 31, 2004, permanent differences resulting
          primarily from different book and tax accounting for net operating
          losses and foreign currency gains and losses, were reclassified at
          year end. These reclassifications had no effect on net income, net
          assets or net assets per share of the Fund.

          As of December 31, 2004, 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 (Loss)   (Depreciation)    and Deferrals           Total
                                                     
                    $  -      $61,557,990   $(284,026,204)   $(222,468,214)


          The difference between book basis and tax basis distributable earnings
          is attributable primarily to timing differences on wash sales.

          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. As determined at December 31, 2004, the Fund
          had unused capital loss carryforwards available for Federal income tax
          purposes to offset net realized capital gains, if any, as follows:



                                            Expiring in:
                                                    2009           2010
                                                         
                                            $213,906,407    $70,119,797


     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.

     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

                                       12


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

          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 Board, 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 ("Quality Fund"), which is managed by State Street
          Bank and Trust Company ("State Street") pursuant to guidelines
          approved by the Trust's investment manager. Neuberger guaranteed a
          certain amount of 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. For the year ended December 31, 2004,
          Neuberger did not receive any revenue under the Agreement.

          The Agreement has been renewed and approved by the Board as of July 1,
          2004 with substantially the same terms. Under this current Agreement,
          Neuberger guarantees a certain amount of revenue to the Fund and
          receives any revenue earned in excess of the guaranteed amount as a
          lending agency fee. Income earned on the securities loaned, if any, is
          reflected in the Statement of Operations under the caption Income from
          securities loaned-affiliated issuer.

          In February of 2005, it is likely that the Fund will change the
          collateral investment vehicle from the Quality Fund, managed by State
          Street, to a fund managed by Lincoln Capital, an affiliate, as
          approved by the Board.

     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") and the Neuberger Berman
          Prime Money Fund ("Prime Money"), affiliated funds, which are managed
          by Management and have the same Board members as the Fund. The Cash

          the Fund invests in the Cash Fund or Prime Money, Management waives a
          portion of its management fee equal to the management fee it receives
          from the Cash Fund and Prime Money on those assets. For the year ended
          December 31, 2004, such waived fees amounted to $619 and $3 for the
          Cash Fund and Prime Money, respectively. For the year ended December
          31, 2004, income earned on the investments of the Cash Fund and Prime
          Money amounted to $6,356 and $80, respectively, and is reflected in
          the Statement of Operations under the caption Income from investments
          in affiliated issuers.

     12   Indemnifications: Like many other companies, the Trust's
          organizational documents provide that its officers and trustees are
          indemnified against certain liabilities arising out of the performance
          of their duties to the Trust. In addition, both in some of its
          principal service contracts and in the normal course of its business,
          the Trust enters into contracts that provide indemnifications to other
          parties for certain types of losses or liabilities. The Trust's
          maximum exposure under these arrangements is unknown as this could
          involve future claims against the Trust.

          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 this
          agreement.

          The Board adopted a non-fee distribution plan for the Fund.

          Management has contractually undertaken through December 31, 2008 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 the Fund's average
          daily net assets (the "Expense Limitation"). For the year ended
          December 31, 2004, no reimbursement to the Fund was required. The Fund
          has agreed to repay Management through December 31, 2011 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 year
          ended December 31, 2004, there was no reimbursement to Management

          under this agreement. At December 31, 2004, the Fund has no contingent
          liability to Management under this 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
          year ended December 31, 2004, the impact of this arrangement was a
          reduction of expenses of $34,020.

          The Fund has an expense offset arrangement in connection with its
          custodian contract. For the year ended December 31, 2004, the impact
          of this arrangement was a reduction of expenses of $77.

          Note C--Securities Transactions:

          During the year ended December 31, 2004, there were purchase and sale
          transactions (excluding short-term securities) of $169,583,313 and
          $206,145,170, respectively.

          During the year ended December 31, 2004, brokerage commissions on
          securities transactions amounted to $526,361, of which Neuberger
          received $0, Lehman received $96,582, and other brokers received
          $429,779.

          Note D--Fund Share Transactions:

          Share activity for the years ended December 31, 2004, and December 31,
          2003 was as follows:

          Note E--Line of Credit:

          At December 31, 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 all or any part of the $150,000,000 at
          any particular time. The Fund had no loans outstanding pursuant to
          this line of credit at December 31, 2004, nor had the Fund utilized
          this line of credit at any time prior to that date.

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Growth Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Growth Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as
of December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Growth Portfolio of Neuberger Berman Advisers Management Trust at December 31,
2004, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and its
financial highlights for each of the five years in the period then ended, in
conformity with U.S. generally accepted accounting principles.

Guardian Portfolio Manager's Commentary
- ---------------------------------------

For much of 2004, stocks languished as investors ignored the healthy economy
and good corporate earnings growth, but obsessed over Federal Reserve
tightening, high energy prices, global tensions, and a tightly contested
national election. Then, toward the end of October, investors began
accentuating the positive and stocks rallied, as broad-based market indices
closed the year with respectable gains. The Neuberger Berman AMT Guardian
Portfolio slightly underperformed the Russell 1000 Value Index but materially
outperformed the S&P 500 for the year.(2)

In 2004, our Industrial sector investments had the most positive impact on
absolute returns, with defense electronics manufacturer L-3 Communications and
Canadian National Railway among our top performers. Health Care holdings also
helped returns, with managed care bellwether UnitedHealth Group and laboratory
testing company Quest Diagnostics finishing with strong results. Finally,
Energy investments enhanced performance, buoyed by exploration and production
companies Newfield Exploration and EOG Resources.

Energy stocks performed exceptionally well due to strong oil and natural gas
prices. We had found some great Energy bargains and consequently entered the
year with a material overweight in the group. However, late in the year, some of
the factors that had contributed to strong commodity prices--most notably rising
demand due to robust economic growth in the U.S. and China and constrained
supply resulting from supply disruptions in Iraq, Venezuela, and the Gulf of
Mexico--appeared to have run their course. As a result, energy inventories rose
to comfortable levels. Going forward, Japan is likely to reduce its oil
dependency by reopening some nuclear plants, while China has three coal-fired
generating plants coming on line soon. Consequently, we may see oil prices
moderate. As a result, we thought it prudent to sell into strength and by
year-end 2004, Energy had gone from an overweight to a near-neutral weighting
versus the S&P 500 Index.

Information Technology investments, primarily semiconductor and semiconductor
equipment makers such as Altera, Texas Instruments, and Teradyne, were our
Achilles' heel in 2004. These stocks were pressured when the economy stalled
this summer and chip makers were left holding excess inventory. However, with
the strength of end-market demand for technology products, we believe this
inventory imbalance has largely been worked off, and note that Intel has
announced it expects wafer starts to increase in the first quarter. If this
proves to be an industry-wide trend, revenues should recover quickly. With the
enormous operating leverage in this business, 2005 earnings could be far better
than Wall Street is expecting. This should help improve sentiment toward
technology stocks, which turned strongly negative at mid-year.

As is our custom, we will detail a portfolio holding that demonstrates our
investment discipline. Canadian National Railway is what we believe to be the
most efficient railroad in North America. The company pioneered scheduled
freight delivery when its competitors were forcing their customers to wait for
shipments until they booked full loads. The premium price Canadian National's
customers were willing to pay for scheduled delivery more than compensated for
trains going out without full loads. A number of trends favor the company. In
the long term, with manufacturing continuing to migrate overseas to
low-labor-cost nations, businesses that help to efficiently transport goods
from the coasts to the heartland should profit. In the intermediate term,
railroads' favorable cost structure should facilitate market share gains from
truckers. In our opinion, Canadian National's big short-term edge is that it
has steadily invested in its

                                       1

infrastructure and has been able to handle increased demand without
bottlenecks, giving it substantial earnings leverage as the economy has
improved. Despite the stock's excellent performance this year, it still meets
our value parameters and we are still "all aboard."

In closing, we thank AMT Guardian shareholders for their confidence in our
research-driven, value-oriented investment discipline and hope to continue to
earn their trust in the years ahead.

Sincerely,

     1.   For Class I, 15.81%, 2.26%, and 8.38% were the average annual total
          returns for the 1-, 5-year and since inception (11/03/97) periods
          ended December 31, 2004. For Class S, 15.55%, 2.13% and 8.28% were the
          average annual total returns for the 1-year, 5-year and since
          inception of Class I (11/03/97) periods ended December 31, 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. The
          performance information does not reflect fees and expenses of the
          insurance companies.

     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 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 directly 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.

Information About Your Fund's Expenses
- --------------------------------------

This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:


                                              
                                Actual Expenses: The first section of the table provides information about
                                                 actual account values and actual expenses in dollars. You
                                                 may use the information in this line, together with the
                                                 amount you invested, to estimate the expenses you paid over
                                                 the period.

   Hypothetical Example for Comparison Purposes: The second section of the table provides information about
                                                 hypothetical account values and hypothetical expenses based
                                                 on the Fund's actual expense ratio and an assumed rate of
                                                 return at 5% per year before expenses. This return is not
                                                 the Fund's actual return. The hypothetical account values
                                                 and expenses may not be used to estimate the actual ending
                                                 account balance or expenses you paid for the period. You may
                                                 use this information to compare the ongoing costs of
                                                 investing in this Fund versus other funds. To do so, compare
                                                 this 5% hypothetical example with the 5% hypothetical
                                                 examples that appear in the shareholder reports of other
                                                 funds.

*    For each class of the Fund, expenses are equal to the expense ratio for the
     class, multiplied by the average account value over the period, multiplied
     by 184/366 (to reflect the one-half year period shown).

**   Hypothetical 5% annual return before expenses is calculated by multiplying
     the number of days in the most recent half year divided by 366.

Notes to Schedule of Investments Guardian Portfolio
- ---------------------------------------------------

+    Investments in equity securities by Neuberger Berman Advisers Management
     Trust Guardian Portfolio (the "Fund") are valued at the latest sale 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 and 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 noon, 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. When changes in the
     value of a certain index suggest that the closing prices on the foreign
     exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income tax
     purposes was $140,144,809. Gross unrealized appreciation of investments was
     $49,353,289 and gross unrealized depreciation of investments was $120,059,
     resulting in net unrealized appreciation of $49,233,230, based on cost for
     U.S. Federal income tax purposes.

*    Non-income producing security.

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

@    Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
     Neuberger Berman Management Inc. (see Notes A & F of Notes to Financial
     Statements) and may be considered an affiliate since it has the same
     officers, Board members, and investment manager as the Fund and because, at
     times, the Fund may own 5% or more of the outstanding voting securities of
     Prime Money.

++   The N&B Securities Lending Quality Fund, LLC ("Quality Fund") is an
     investment vehicle established by the Fund's custodian to invest cash the
     Fund receives as collateral for securities loans. The Fund's shares in the
     Quality Fund are non-voting. However, because all shares of the Quality
     Fund are held by funds in the related investment management complex, the
     Quality Fund may be considered an affiliate of the Fund (see Notes A & F of
     Notes to Financial Statements).

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 eleven
          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 (the "Board") 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 U.S.
          generally accepted accounting principles 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 noon, 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, if any, 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 year
          ended December 31, 2004 was $98,457.

     5    Income tax information: 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 requirements of Subchapter M of the Internal Revenue Code
          applicable to regulated

                                       10



                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

investment companies and to distribute substantially all of its earnings to its
shareholders. Therefore, no Federal income or excise tax provision is required.

Income dividends and capital gain distributions are determined in accordance
with income tax regulations, which may differ from generally accepted
accounting principles. These differences are primarily due to differing
treatments of income and gains on various investment securities held by the
Fund, timing differences and differing characterization of distributions made
by the Fund as a whole. The Fund may also utilize earnings and profits
distributed to shareholders on redemption of shares as a part of the dividends
paid deduction for income tax purposes.

As determined on December 31, 2004, permanent differences resulting primarily
from different book and tax accounting for distributions from real estate
investment trusts and foreign currency gains and losses, were reclassified at
year end. These reclassifications had no effect on net income, net assets or
net assets per share of the Fund.

The tax character of distributions paid during the years ended December 31,
2004 and December 31 2003 were as follows:




Distributions Paid From:
                               Ordinary Income                    Total

                                                           
                             2004            2003          2004            2003
                         $201,368      $1,313,998      $201,368      $1,313,998


As of December 31, 2004, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:



                                     Unrealized              Loss
               Undistributed       Appreciation     Carryforwards
             Ordinary Income     (Depreciation)     and Deferrals         Total
                                                           
                    $408,415        $49,232,846     $(45,792,444)    $3,848,817


The difference between book basis and tax basis distributable earnings is
attributable primarily to timing differences on wash sales, return of capital
distributions from real estate investment trusts, and post-October losses.

Under current tax law, certain net capital and net foreign currency losses
realized after October 31, 2004 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, 2004, the fund elected to defer $341,556 net capital losses
arising between November 1, 2004 and December 31, 2004.

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. As determined at December 31, 2004, the Fund had unused capital loss
carryforwards available for Federal income tax purposes to offset net realized
capital gains, if any, as follows:



Expiring in:
                                         2009              2010            2011
                                                              
                                   $  852,650       $39,047,105      $5,551,133

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

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.

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. 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 Board, 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
     ("Quality Fund"), which is managed by State Street Bank and Trust Company
     ("State Street") pursuant to guidelines approved by the Trust's investment
     manager. Neuberger guaranteed a certain amount of 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 as of July 1, 2004
     with substantially the same terms. Under this current Agreement, Neuberger
     guarantees a certain amount of revenue to the Fund and receives any revenue
     earned in excess of the guaranteed amount as a lending agency fee. For the
     year ended December 31, 2004, Neuberger did not receive any revenue 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-affiliated issuer.

     In February of 2005, it is likely that the Fund will change the collateral
     investment vehicle from the Quality Fund, managed by State Street, to a
     fund managed by Lincoln Capital, an affiliate, approved by the Board.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

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") and the Neuberger Berman Prime Money Fund ("Prime
     Money"), affiliated funds, which are managed by Management and have the
     same Board members as the Fund. The Cash Fund and Prime Money each 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 or Prime Money, Management waives a
     portion of its management fee equal to the management fee it receives from
     the Cash Fund and Prime Money on those assets. For the year ended December
     31, 2004, such waived fees amounted to $3,440 and $60 for the Cash Fund and
     Prime Money, respectively. For the year ended December 31, 2004, income
     earned on the investments of the Cash Fund and Prime Money amounted to
     $37,811 and $1,406, respectively, and is reflected in the Statement of
     Operations under the caption Income from investments in affiliated issuers.

12   Indemnifications: Like many other companies, the Trust's organizational
     documents provide that its officers and trustees are indemnified against
     certain liabilities arising out of the performance of their duties to the
     Trust. In addition, both in some of its principal service contracts and in
     the normal course of its business, the Trust enters into contracts that
     provide indemnifications to other parties for certain types of losses or
     liabilities. The Trust's maximum exposure under these arrangements is
     unknown as this could involve future claims against the Trust.

13   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 this agreement.

     The Board 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 Board has 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, 2008 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 year ended December 31, 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, 2011 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 year ended December 31, 2004, there was no
     reimbursement to Management under these agreements. At December 31, 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.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     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 year ended
     December 31, 2004, the impact of this arrangement was a reduction of
     expenses of $9,114.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. For the year ended December 31, 2004, the impact of this
     arrangement, was a reduction of expenses of $51.

     Note C--Securities Transactions:

     During the year ended December 31, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $39,861,848 and

     Note E--Line of Credit:

     At December 31, 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 all or any part of the
     $150,000,000 at any particular time. The Fund had no loans outstanding
     pursuant to this line of credit at December 31, 2004, nor had the Fund
     utilized this line of credit at any time prior to that date.

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

      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

      reduce the total return for all fiscal periods shown. Performance data

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Guardian Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Guardian Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as
of December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian and brokers or other
appropriate auditing procedures where replies from brokers were not received.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Guardian Portfolio of Neuberger Berman Advisers Management Trust at December
31, 2004, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended, and its
financial highlights for each of the periods indicated therein, in conformity
with U.S. generally accepted accounting principles.

High Income Bond Portfolio Manager's Commentary
- -----------------------------------------------

From its inception on September 15, 2004 through the end of the reporting
period on December 31, 2004, the Neuberger Berman AMT High Income Bond
Portfolio provided a total return of 2.43%, compared to a gain of 2.82% for its
benchmark, the Lehman Brothers Intermediate Ba U.S. High Yield Index.2 Although
the portfolio has only been open a short time, we are pleased with its results
so far.

I would like to take this opportunity to welcome our shareholders and reiterate
our investment approach to the high-yield market. The portfolio focuses on
higher quality high-yield bonds where we find value versus U.S. Treasury
securities of corresponding maturities. This results in a portfolio that seeks
to maintain an average credit quality of "Ba3" from Moody's or "BB-" from
Standard & Poor's.

In managing the portfolio, we diversify its assets across a broad range of
issuers and industries, and normally expect to maintain an assumed
dollar-weighted average maturity of between five and seven years. We seek to
manage credit risk and minimize interest rate risk through credit analysis,
diversification, and an emphasis on short- to intermediate-term maturities.
Depending on market- and issuer-specific conditions, we generally sell any
bonds within a reasonable period of time after they fall below a rating of "B3"
from Moody's or "B-" from Standard & Poor's.

In general, high-yield bonds generated strong gains over the 12-month reporting
period as their spreads over Treasuries narrowed steadily, reflecting healthy
economic conditions, as well as stronger corporate balance sheets. Over the
last several years, more stringent cost controls have helped many companies
improve profit margins, while low interest rates have allowed them to
restructure their debt and reduce their financing costs. In 2004, the weakening
dollar benefited many industrial issuers: utilities were able to repair their
balance sheets and enjoy credit upgrades, and energy companies capitalized on
high oil prices.

Looking forward, an expanding economy with moderate inflation would provide a
positive backdrop for the high-yield market, even if the Federal Reserve
continues to increase rates. Within this sector, of course, a relatively
cautious approach is always appropriate.

Sincerely,

/s/Wayne C. Plewniak

              1. 2.43% was the cumulative total return from September 15, 2004
                 (its date of inception) through December 31, 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. The
                 performance information does not reflect fees and expenses of
                 the insurance companies.

              2. Lehman Brothers Intermediate Ba U.S. High Yield Index is an
                 unmanaged index comprised of BB rated bonds with maturities of
                 less than 10 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
                 is prepared or obtained by NBMI and includes reinvestment of
                 all dividends and capital gain distributions. The Portfolio
                 many invest in many securities not included in the
                 above-described index.

                 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.

Information About Your Fund's Expenses
- --------------------------------------

This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:



                                                 
                                    Actual Expenses:    The first section of the
                                                        table provides
                                                        information about actual
                                                        account values and
                                                        actual expenses in
                                                        dollars. You may use the
                                                        information in this
                                                        line, together with the
                                                        amount you invested, to
                                                        estimate the expenses
                                                        you paid over the
                                                        period.

       Hypothetical Example for Comparison Purposes:    The second section of
                                                        the table provides
                                                        information about
                                                        hypothetical account
                                                        values and hypothetical
                                                        expenses based on the
                                                        Fund's actual expense
                                                        ratio and an assumed
                                                        rate of return at 5% per
                                                        year before expenses.
                                                        This return is not the
                                                        Fund's actual return.
                                                        The hypothetical account
                                                        values and expenses may
                                                        not be used to estimate
                                                        the actual ending
                                                        account balance or
                                                        expenses you paid for
                                                        the period. You may use
                                                        this information to
                                                        compare the ongoing
                                                        costs of investing in
                                                        this Fund versus other
                                                        funds. To do so, compare
                                                        this 5% hypothetical

Notes to Schedule of Investments High Income Bond Portfolio
- -----------------------------------------------------------
+ Investments in securities by Neuberger Berman Advisers Management Trust High
  Income Bond Portfolio (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 and 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 noon, 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 December 31, 2004, the cost of investments for U.S. Federal income tax
  purposes was $3,011,020. Gross unrealized appreciation of investments was
  $27,667 and gross unrealized depreciation of investments was $21,985,
  resulting in net unrealized appreciation of $5,682, 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 and are deemed liquid. At
  December 31, 2004, these securities amounted to $513,125 or 16.7% of net
  assets.

              no operations until September 15, 2004, other than matters
              relating to its organization and registration of its shares as a
              Series of the Trust under the 1933 Act. The Fund currently offers
              only Class S shares. The Board of Trustees of the Trust (the
              "Board") 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 U.S.
              generally accepted accounting principles 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
              noon, 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 discount (adjusted for original issue
              discount, where applicable), and amortization of premium, where
              applicable, is recorded on the accrual basis. Realized gains and
              losses from securities transactions and foreign currency
              transactions, if any, are recorded on the basis of identified cost
              and stated separately in the Statement of Operations.

            5 Income tax information: The Funds are treated as separate
              entities for U.S. Federal income tax purposes. It is the intention
              of the Fund to qualify as a regulated investment company by
              complying with the requirements of Subchapter M of the Internal
              Revenue Code applicable to regulated investment companies and to
              distribute substantially all of its earnings to its shareholders.
              Therefore, no Federal income or excise tax provision is required.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

              Income dividends and capital gain distributions are determined in
              accordance with income tax regulations, which may differ from
              generally accepted accounting principles. These differences are
              primarily due to differing treatments of income and gains on
              various investment securities held by the Fund, timing differences
              and differing characterization of distributions made by the Fund
              as a whole. The Fund may also utilize earnings and profits
              distributed to shareholders on redemption of shares as a part of
              the dividends paid deduction for income tax purposes.

              As determined on December 31, 2004, permanent differences
              resulting primarily from different book and tax accounting for
              characterization of distributions made by the Fund and
              non-deductible start-up costs were reclassified at year end. These
              reclassifications had no effect on net income, net assets or net
              assets per share of the Fund.

              The tax character of distributions paid during the period ended
              December 31, 2004 was as follows:

Distributions Paid From:
                                                                 Ordinary Income
                                                                         $45,990

As of December 31, 2004, the components of distributable earnings (accumulated
losses) on a U.S. Federal income tax basis were as follows:



                          Unrealized              Loss
    Undistributed       Appreciation     Carryforwards
  Ordinary Income     (Depreciation)     and Deferrals      Total
                                                 
          $23,356             $5,682               $--    $29,038


There were no differences between book basis and tax basis distributable
earnings.

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.

            6 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.

            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 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 Indemnifications: Like many other companies, the Trust's
              organizational documents provide that its officers and trustees
              are indemnified against certain liabilities arising out of the
              performance of their duties to the Trust. In addition, both in
              some of its principal service contracts and in the normal course
              of its business, the Trust enters into contracts that provide
              indemnifications to other parties for certain types of losses or
              liabilities. The Trust's maximum exposure under these arrangements
              is unknown as this could involve future claims against the Trust.

              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 0.48% of its
              average daily net assets.

              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 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
              this agreement.

              Management acts as agent in arranging for the sale of Fund shares
              without commission and bears advertising and promotion expenses.
              The Board has 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 the Fund's 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, 2008
              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,
              1.10% per annum of the Fund's average daily net assets (the
              "Expense Limitation"). For the period ended December 31, 2004,
              such excess expenses amounted to $31,571. The Fund has agreed to
              repay Management through December 31, 2011 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 period ended December 31, 2004, there was no
              reimbursement to Management under this agreement. At December 31,
              2004, contingent liabilities to Management under this agreement
              were as follows:



                                                                     Expiring in

                                                                         $31,571


Management and Neuberger Berman, LLC ("Neuberger"), a member firm of the New
York Stock Exchange and sub-adviser to the Fund, are indirect wholly-owned
subsidiaries of Lehman Brothers Holdings Inc., 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.
Currently, Neuberger is the Fund's sole shareholder. 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. For the period ended December 31, 2004, the impact of this
arrangement was a reduction of expenses of $229.

Note C--Securities Transactions:

Cost of purchases and proceeds of sales and maturities of long-term securities
for the period ended December 31, 2004 were as follows:



                                                                      Sales and

Note E--Line of Credit:

At December 31, 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 all or any
part of the $150,000,000 at any particular time. The Fund had no loans
outstanding pursuant to this line of credit at December 31, 2004, nor had the
Fund utilized this line of credit at any time prior to that date.

++     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.

       certain expenses. The total return information shown does not reflect
       charges and other expenses that apply to the separate account or the

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Shareholders and Board of Trustees of
High Income Bond Portfolio, a Series of
Neuberger Berman Advisers Management Trust
New York, New York

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of High Income Bond Portfolio, a series of
Neuberger Berman Advisers Management Trust, as of December 31, 2004, and the
related statement of operations, the statement of changes in net assets, and
the financial highlights for the period from September 15, 2004 (commencement
of operations) to December 31, 2004. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audit.

We conducted our audit in accordance with standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures
included confirmation of securities owned as of December 31, 2004 by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of High
Income Bond Portfolio as of December 31, 2004, the results of its operations,
the changes in its net assets and the financial highlights for the period from
September 15, 2004 to December 31, 2004, in conformity with accounting
principles generally accepted in the United States of America.

Limited Maturity Bond Portfolio Managers' Commentary
- ----------------------------------------------------
The Neuberger Berman AMT Limited Maturity Bond Portfolio provided modestly
positive returns in 2004, slightly trailing its benchmark, the Merrill Lynch
1-3 Year Treasury Index.(2)

Mixed economic signals kept bond investors guessing in 2004. In the first
quarter, despite several consecutive quarters of strong Gross Domestic Product
(GDP) growth, investors seemed to doubt that the economic recovery was for
real. As a result, bond prices were quite stable. Then, investors' doubts over
the strength of the economy evaporated with the April 2 release of a
surprisingly strong March jobs report, and bond prices started to fall. A
healthy April jobs report kept the pressure on bond prices. Then in June, with
rapidly rising oil prices and uncertainty spawned by a tight Presidential
election race, economic growth began to slow. Investors came back to bonds,
prices firmed, and yields stabilized. The market then went into wait-and-see
mode for a few months, before yields began to rise again during the fourth
quarter.

We started fiscal 2004 in a defensive posture, with a below benchmark duration
(sensitivity to interest rates) of 1.3 years. Our caution reflected our
recognition that low bond yields provided a thin cushion to offset potential
price declines in an economy that appeared to be gaining momentum. We
maintained a low duration at the end of March, prior to the release of the
strong jobs report. This conservative duration posture helped shield
shareholder capital as bonds retreated in April and May. We ended the year at a
modestly conservative 1.6-year duration. For full-year 2004, our generally
conservative duration management enhanced returns.

Shifts in sector allocation throughout the year were designed to take advantage
of evolving opportunities in the market. Much of our sector realignment came in
the fourth quarter as we enhanced portfolio yield by reducing our allocation to
Treasuries and increased our exposure to high-credit-quality alternatives
including asset-backed, corporate, and government agency securities. As lower
rated credit spreads narrowed versus higher grade alternatives, we upgraded our
corporate portfolio by reducing exposure to relatively less creditworthy
issuers. We also reduced our weighting in mortgage-backed securities to almost
zero, because mortgages tend to underperform during periods of interest rate
volatility.

By year-end 2004, the Federal Reserve had instituted five 25-basis-point rate
hikes and the Fed Funds rate stood at 2.25%. We believe that the Fed will
continue to raise rates at a "measured pace" with the Fed Funds rate probably
reaching 3.5% by year-end 2005. The election is over and President Bush appears
to have a mandate to perpetuate what many investors consider pro-business
policies. Job growth has regained momentum, indicating that the economy has
emerged from the summer doldrums and is now back on a solid footing. A healthy
economy may continue to keep pressure on bond prices. Consequently, we believe
it is prudent to maintain the portfolio's below benchmark duration. We are
likely to continue attempting to enhance portfolio yield by diversifying away
from Treasuries to other high quality, higher yielding sectors.

In closing, we continually monitor economic trends that may affect U.S.
interest rates and bond prices. Among the things we are watching closely are
the valuation of the U.S. dollar, the potential revaluation of the Chinese
currency, and America's federal budget and current account deficits. Moving
forward, the portfolio posture that served our

investors well in 2004 will remain in place until our view of the economy and
fixed income markets begins to change. Over the long term, we believe that we
can add value through prudent duration management, sector allocation, and
security selection without exposing shareholders to above-market risk.

     1.   0.78%, 4.78% and 5.15% were the average annual total returns for the
          1-, 5- and 10-year periods ended December 31, 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.
          The performance information does not reflect fees and expenses of the
          insurance companies.

     2.   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 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  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 in their separate accounts that fund variable annuity
          and variable life insurance policies and by qualified pension and
          retirement plans.

Information About Your Fund's Expenses
- --------------------------------------

This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:


                                                
                                   Actual Expenses: The first section
                                                    of the table provides
                                                    information about actual
                                                    account values and actual
                                                    expenses in dollars. You may
                                                    use the information in this
                                                    line, together with the
                                                    amount you invested, to
                                                    estimate the expenses you
                                                    paid over the period.

 Hypothetical Example for Comparison Purposes:      The second section
                                                    of the table provides
                                                    information about
                                                    hypothetical account values
                                                    and hypothetical expenses
                                                    based on the Fund's actual
                                                    expense ratio and an assumed
                                                    rate of return at 5% per
                                                    year before expenses. This
                                                    return is not the Fund's
                                                    actual return. The
                                                    hypothetical account values
                                                    and expenses may not be used
                                                    to estimate the actual
                                                    ending account balance or
                                                    expenses you paid for the
                                                    period. You may use this
                                                    information to compare the
                                                    ongoing costs of investing
                                                    in this Fund versus other
                                                    funds. To do so, compare
                                                    this 5% hypothetical example
                                                    with the 5% hypothetical
                                                    examples that appear in the
                                                    shareholder reports of other
                                                    funds.

     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 and
     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 noon, 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.

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 eleven
     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 (the "Board") 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.

     operating series of Neuberger Berman Advisers Management Trust (the

     accepted accounting principles 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 noon, 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
     discount (adjusted for original issue discount, where applicable) and
     amortization of premium, where applicable, is recorded on the accrual
     basis. Realized gains and losses from securities transactions and foreign
     currency transactions, if any, 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

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     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.

7    Income tax information: 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
     requirements of Subchapter M of the Internal Revenue Code applicable to
     regulated investment companies and to distribute substantially all of its
     earnings to its shareholders. Therefore, no Federal income or excise tax
     provision is required.

     Income dividends and capital gain distributions are determined in
     accordance with income tax regulations, which may differ from generally
     accepted accounting principles. These differences are primarily due to
     differing treatments of income and gains on various investment securities
     held by the Fund, timing differences and differing characterization of
     distributions made by the Fund as a whole. The Fund may also utilize
     earnings and profits distributed to shareholders on redemption of shares as
     a part of the dividends paid deduction for income tax purposes.

     As determined on December 31, 2004, permanent differences resulting
     primarily from different book and tax accounting for foreign currency gains
     and losses, paydown gains and losses, amortization of bond premium, and
     mortgage dollar rolls, were reclassified at year end. These
     reclassifications had no effect on net income, net assets or net assets per
     share of the Fund.

     The tax character of distributions paid during the years ended December 31,
     2004 and December 31, 2003 were as follows:



Distributions Paid From:
                               Ordinary Income                    Total
                           2004           2003           2004           2003
                                                              
                          $11,800,669    $14,350,033    $11,800,669    $14,350,033


     As of December 31, 2004, the components of distributable earnings
     (accumulated losses) on a U.S. Federal income tax basis were as follows:



                                 Unrealized            Loss
              Undistributed     Appreciation   Carryforwards
             Ordinary Income   (Depreciation)   and Deferrals         Total
                                                        
              $9,539,330        $(2,911,393)     $(16,206,309)   $(9,578,372)


     The difference between book basis and tax basis distributable earnings is
     attributable primarily to timing differences on wash sales, mark to market
     on certain forward foreign currency contracts, amortization of bond
     premium, and Post-October losses.

     Under current tax law, certain net 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, 2004, the fund elected to defer $633,692 net
     capital losses arising between November 1, 2004 and December 31, 2004.

     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. As determined at December 31, 2004, the Fund had
     unused capital loss carryforwards available for Federal income tax purposes
     to offset net realized capital gains, if any, as follows:



 Expiring in
        2005         2006         2007         2008        2012
                                          
     $21,426   $2,478,607   $3,975,890   $6,386,624   $2,710,070


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.

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

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

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
     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.

12   Dollar rolls: The Fund may enter into dollar roll transactions with respect
     to mortgage-backed securities. In a dollar roll transaction, the Fund sells
     securities for delivery in the current month and simultaneously agrees to
     repurchase substantially similar (i.e., same type and coupon) securities on
     a specified future date from the same party. During the period before the
     repurchase, the Fund foregoes principal and interest payments on the
     securities. The Fund is compensated by the difference between the current
     sales price and the forward price for the future purchase (often referred
     to as the "drop"), as well as by the interest earned on the cash proceeds
     of the initial sale. Dollar rolls may increase fluctuations in the Fund's
     net asset value and may be viewed as a form of leverage. There is a risk
     that the counter party will be unable or unwilling to complete the
     transaction as scheduled, which may result in losses to the Fund.

13   Indemnifications: Like many other companies, the Trust's organizational
     documents provide that its officers and trustees are indemnified against
     certain liabilities arising out of the performance of their duties to the
     Trust. In addition, both in some of its principal service contracts and in
     the normal course of its business, the Trust enters into contracts that
     provide indemnifications to other parties for certain types of losses or
     liabilities. The Trust's maximum exposure under these arrangements is
     unknown as this could involve future claims against the Trust.

     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

                                       15

     $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 this agreement.

     The Board adopted a non-fee distribution plan for the Fund.

     Management has contractually undertaken through December 31, 2008 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 the Fund's average daily net assets (the
     "Expense Limitation"). For the year ended December 31, 2004, no
     reimbursement to the Fund was required. The Fund has agreed to repay
     Management through December 31, 2011 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 year ended December 31, 2004, there
     was no reimbursement to Management under this agreement. At December 31,
     2004, the Fund has no contingent liability to Management under this
     agreement.

     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.,
     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. For the year ended December 31, 2004, the impact of this
     arrangement was a reduction of expenses of $1,774.

     Note C--Securities Transactions:

     Cost of purchases and proceeds of sales and maturities of long-term
     securities (excluding financial futures contracts and foreign currency
     contracts) for the year ended December 31, 2004 were as follows:

     Note E--Line of Credit:

     At December 31, 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 all or any part of the
     $150,000,000 at any particular time. The Fund had no loans outstanding
     pursuant to this line of credit at December 31, 2004, nor had the Fund
     utilized this line of credit at any time prior to that date.

     +    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.

     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:

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Limited Maturity Bond Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Limited Maturity Bond Portfolio, one of the
series constituting the Neuberger Berman Advisers Management Trust (the
"Trust"), as of December 31, 2004, and the related statement of operations for
the year then ended, the statement of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian and brokers or other
appropriate auditing procedures where replies from brokers were not received.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Limited Maturity Bond Portfolio of Neuberger Berman Advisers Management Trust
at December 31, 2004, the results of its operations for the year then ended,
the changes in its net assets for each of the two years in the period then
ended, and its financial highlights for each of the five years in the period
then ended, in conformity with U.S. generally accepted accounting principles.

Mid-Cap Growth Portfolio Managers' Commentary
- ---------------------------------------------

The Neuberger Berman AMT Mid-Cap Growth Portfolio posted positive returns for
calendar year 2004, outperforming its benchmark, the Russell Midcap Growth
Index.(2)

Our security selection within the Information Technology (IT), Consumer
Discretionary and Industrial sectors provided the largest contributions to
total returns for the year. Within IT, names that did well included Alliance
Data Systems (ADS) and Apple Computer Inc (AAPL). In Consumer Discretionary,
our emphasis on casinos and gaming was particularly additive to performance.
Industrial stocks that outperformed included JB Hunt Transport Services (JBHT)
and Corporate Executive Board (EXBD). Our emphasis on the services area of
Financials helped results, with strong performers including First Marblehead
(FMD) and Capitalsource Inc (CSE). Energy was again additive, as companies like
XTO Energy (XTO), with the ability to increase reserves or production of oil
and gas, generated strong returns. Although, in aggregate, our sector
allocation detracted from the year's results, our overweight in Telecom, one of
the strongest performing sectors, was additive.

On the downside, our stock selection within Health Care had the most negative
impact on relative portfolio performance. The environment for generic
pharmaceuticals was particularly weak given the lack of pricing power in the
industry. Our stock selection within Materials, representing 2-3% of the
benchmark, also hurt returns.

Looking ahead to 2005, we believe that economic headwinds should act to slow
economic growth from the 4% pace achieved in 2004. Tighter fiscal and monetary
policies, slowing Asian economies, the need for U.S. consumers to increase
savings, higher energy costs and a normal mid-cycle deceleration all may come
into play. This is not to say that we believe the economy is in much danger of
decline. "Real" (after inflation) interest rates remain historically low, while
the Fed remains on a "measured pace" to raise rates. In addition, corporate
spreads and the yield curve indicate continued economic expansion, and
corporate hiring and investment plans appear intact.

As a result, we believe that 2005 should prove favorable for equity investors.
Although, in our opinion, keeping inflation in check is a key to further equity
market advancement, the equity market's technicals appear healthy in the near
term. After the strong late-year market gains, sparked by the Presidential
election results and drop in crude oil prices, we expect stocks to pull back in
the weeks ahead, before moving higher again. Because we believe that the market
remains in a rally phase, we want to be positioned more aggressively than the
indices and our competition, in stocks we believe have more potential upside in
a rising market.

However, if the market advances in the first part of 2005, we currently
anticipate making rotational changes in the portfolio into more defensive
areas, such as Consumer Staples and Health Care. Currently, we are neutrally
weighted in Materials and Industrials, and underweight in Consumer Staples and
Utilities. Although Information Technology and Energy sectors are both
neutrally weighted, we expect to be sellers of technology and buyers of energy
over the longer term.

The chart shows the value of a hypothetical $10,000 investment in the Fund over
the past 10 fiscal years, or since the Fund's inception, if it has not operated
for 10 years. The graphs are based on Class I shares only; performance of other
classes will vary due to differences in fee structures (see Average Annual Total
Return chart above). The results are compared with benchmarks, which may include
a broad-based market index and/or a narrower index. Please note that market
indexes do not include expenses. All results include the reinvestment of
dividends and capital gain distributions. Results represent past performance and
do not indicate future results. The chart and table do not reflect the deduction
of taxes that a shareholder would pay on Fund distributions or the redemption of
Fund shares.

          1.   For Class I, 16.31%, (6.00%) and 8.91% were the average annual
               total returns for the 1-year, 5-year and since inception
               (11/03/97) periods ended December 31, 2004. For Class S, 16.03%,
               (6.10%) and 8.83% were the average annual total returns for the
               1-year, 5-year and since inception of Class I (11/03/97) periods
               ended December 31, 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 that 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. 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. The performance
               information does not reflect fees and expenses of the insurance
               companies.

          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 26% 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 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.

Information About Your Fund's Expenses
- --------------------------------------

This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:




                                          
                              Actual Expenses:  The first section of the table
                                                provides information about
                                                actual account values and actual
                                                expenses in dollars. You may use
                                                the information in this line,
                                                together with the amount you
                                                invested, to estimate the
                                                expenses you paid over the
                                                period.

 Hypothetical Example for Comparison Purposes:  The second section of the table
                                                provides information about
                                                hypothetical account values and
                                                hypothetical expenses based on
                                                the Fund's actual expense ratio
                                                and an assumed rate of return at
                                                5% per year before expenses.
                                                This return is not the Fund's
                                                actual return. The hypothetical
                                                account values and expenses may
                                                not be used to estimate the
                                                actual ending account balance or
                                                expenses you paid for the
                                                period. You may use this
                                                information to compare the
                                                ongoing costs of investing in
                                                this Fund versus other funds. To
                                                do so, compare this 5%
                                                hypothetical example with the 5%
                                                hypothetical examples that
                                                appear in the shareholder
                                                reports of other funds.

   class, multiplied by the average account value over the period, multiplied
   by 184/366 (to reflect the one-half year period shown).

** Hypothetical 5% annual return before expenses is calculated by multiplying
   the number of days in the most recent half year divided by 366.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

Notes to Schedule of Investments Mid-Cap Growth Portfolio
- ---------------------------------------------------------

     +    Investments in equity securities by Neuberger Berman Advisers
          Management Trust Mid-Cap Growth Portfolio (the "Fund") are valued at
          the latest sale 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 the 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 and
          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 noon, 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. When changes in
          the value of a certain index suggest that the closing prices on the
          foreign exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income

     @    Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
          Neuberger Berman Management Inc. (see Notes A & F of Notes to
          Financial Statements) and may be considered an affiliate since it has
          the same officers, Board members, and investment manager as the Fund
          and because, at times, the Fund may own 5% or more of the outstanding
          voting securities of Prime Money.

     ++   The N&B Securities Lending Quality Fund, LLC ("Quality Fund") is an
          investment vehicle established by the Fund's custodian to invest cash
          the Fund receives as collateral for securities loans. The Fund's
          shares in the Quality Fund are non-voting. However, because all shares
          of the Quality Fund are held by funds in the related investment
          management complex, the Quality Fund may be considered an affiliate of
          the Fund (see Notes A & F of Notes to Financial Statements).

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

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 eleven 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 (the
     "Board") 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 U.S. generally
     accepted accounting principles 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 noon, 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, if any, 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
     year ended December 31, 2004 was $7,834.

5    Income tax information: 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
     requirements of Subchapter M of the Internal Revenue Code applicable to
     regulated

                                       11

     investment companies and to distribute substantially all of its earnings to
     its shareholders. Therefore, no Federal income or excise tax provision is
     required.

     Income dividends and capital gain distributions are determined in
     accordance with income tax regulations, which may differ from generally
     accepted accounting principles. These differences are primarily due to
     differing treatments of income and gains on various investment securities
     held by the Fund, timing differences and differing characterization of
     distributions made by the Fund as a whole. The Fund may also utilize
     earnings and profits distributed to shareholders on redemption of shares as
     a part of the dividends paid deduction for income tax purposes.

     As determined on December 31, 2004, permanent differences resulting
     primarily from different book and tax accounting for net operating losses
     and foreign currency gains and losses, were reclassified at year end. These
     reclassifications had no effect on net income, net assets or net assets per
     share of the Fund.

     As of December 31, 2004, 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
                                             
           $146,474,302       $ (339,253,743)      $ (192,779,441)


     The difference between book basis and tax basis distributable earnings is
     attributable primarily to timing differences on wash sales.

     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. As determined at December 31, 2004, the Fund had
     unused capital loss carryforwards available for Federal income tax purposes
     to offset net realized capital gains, if any, as follows:



           Expiring in
                  2009              2010             2011
                                        
          $214,771,203      $113,423,118      $11,059,422


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.

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

                                       12


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     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 Board, 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
     ("Quality Fund"), which is managed by State Street Bank and Trust Company
     ("State Street") pursuant to guidelines approved by the Trust's investment
     manager. Neuberger guaranteed a certain amount of 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. For the year ended December
     31, 2004, Neuberger did not receive any revenue under the Agreement.

     The Agreement has been renewed and approved by the Board as of July 1, 2004
     with substantially the same terms. Under this current Agreement, Neuberger
     guarantees a certain amount of revenue to the Fund and receives any revenue
     earned in excess of the guaranteed amount as a lending agency fee. Income
     earned on the securities loaned, if any, is reflected in the Statement of
     Operations under the caption Income from securities loaned-affiliated
     issuer.

     In February of 2005, it is likely that the Fund will change the collateral
     investment vehicle from the Quality Fund, managed by State Street, to a
     fund managed by Lincoln Capital, an affiliate, as approved by the Board.

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") and the Neuberger Berman Prime Money Fund ("Prime
     Money"), affiliated funds, which are managed by Management and have the
     same Board members as the Fund. The Cash Fund and Prime Money each seeks to
     provide as high a level of current

                                       13

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

     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 or Prime Money, Management waives a portion of its management fee
     equal to the management fee it receives from the Cash Fund and Prime Money
     on those assets. For the year ended December 31, 2004, such waived fees
     amounted to $18,087 and $340 for the Cash Fund and Prime Money,
     respectively. For the year ended December 31, 2004, income earned on the
     investment of the Cash Fund and Prime Money amounted to $188,700 and
     $8,018, respectively, and is reflected in the Statement of Operations under
     the caption Income from investments in affiliated issuers.

12   Indemnifications: Like many other companies, the Trust's organizational
     documents provide that its officers and trustees are indemnified against
     certain liabilities arising out of the performance of their duties to the
     Trust. In addition, both in some of its principal service contracts and in
     the normal course of its business, the Trust enters into contracts that
     provide indemnifications to other parties for certain types of losses or
     liabilities. The Trust's maximum exposure under these arrangements is
     unknown as this could involve future claims against the Trust.

13   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 this agreement.

     The Board 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 Board has 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

                                       14


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     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, 2008 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 year ended December 31, 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, 2011 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 year ended December 31, 2004, there was no
     reimbursement to Management under these agreements. At December 31, 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 year ended
     December 31, 2004, the impact of this arrangement was a reduction of
     expenses of $81,783.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. For the year ended December 31, 2004, the impact of this
     arrangement was a reduction of expenses of $116.

     Note C--Securities Transactions:

     During the year ended December 31, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $432,538,173 and
     $443,522,219, respectively.

     During the year ended December 31, 2004, brokerage commissions on
     securities transactions amounted to $1,229,417, of which Neuberger received
     $8, Lehman received $226,575, and other brokers received $1,002,834.

     Note E--Line of Credit:

     At December 31, 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 all or any part of the
     $150,000,000 at any particular time. The Fund had no loans outstanding
     pursuant to this line of credit at December 31, 2004, nor had the Fund
     utilized this line of credit at any time prior to that date.

+     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/higher if Management had not reimbursed, waived and/or
      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.

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Mid-Cap Growth Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Mid-Cap Growth Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as
of December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Mid-Cap Growth Portfolio of Neuberger Berman Advisers Management Trust at
December 31, 2004, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and its financial highlights for each of the periods indicated therein, in
conformity with U.S. generally accepted accounting principles.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

Partners Portfolio Manager's Commentary

Mixed economic signals, record high energy prices, and uncertainty caused by a
close Presidential election restrained stocks for much of 2004. Then, the
clouds over the market began to dissipate. Favorable economic data indicated
that the economy had emerged from its summer doldrums, oil prices declined, and
a decisive Republican victory signaled an extension of current fiscal policies.
Stocks took off and closed 2004 with respectable gains. We are pleased to
report that the Neuberger Berman AMT Partners Portfolio outpaced the Russell
1000 Value Index and significantly outperformed the S&P 500 for the year.(2)


During the reporting period, Energy, Health Care, and Consumer Discretionary
investments provided the largest contribution to our returns. We were modestly
underweight in Energy relative to the Russell index, but due to the exceptional
performance of stocks such as oil shipper Teekay Shipping and natural gas
producer EOG Resources, we generated outsized returns. In the Health Care
arena, our bias favoring health maintenance organizations such as Wellpoint and
pharmaceuticals benefits managers like Caremark RX produced excellent returns.
Homebuilders NVR and Centex, motorcycle manufacturer Harley Davidson, and
retailer Abercrombie & Fitch drove strong results in the Consumer Discretionary
sector.


With positive returns in all ten sectors we own, and better-than-benchmark
results in seven of those ten (versus the Russell index), little went wrong in
2004. We were substantially underweight in the buoyant Consumer Staples and
Utilities sectors. Consumer Staples appeared pricey and we thought we would be
better off investing in Health Care, another less economically sensitive sector
that offered better value. With excellent returns from our Health Care
investments, the decision turned out not to hurt our performance. In hindsight,
we wish we had more exposure to Utilities, the second best performing sector in
both our benchmarks. We clearly underestimated investors' appreciation for
higher yielding stocks, the primary reason behind Utilities' strong
performance.

Currently, we are not contemplating any major shifts in sector allocation. We
believe that many of the stocks that performed well this year will continue to
shine in 2005. For example, we believe that global demand for oil will remain
strong and that the Middle East will be the primary source of incremental
supply to be shipped to the U.S. and China. This is very good news for Teekay
Shipping, which is paid on the basis of tons per mile shipped.

Another example is Caremark RX, a leading Pharmacy Benefits Manager (PBM). PBMs
contract with corporations and HMOs to manage pharmaceutical costs. This is a
growth business, given general concerns over the escalating price of health
care, and should get even better as $40 billion in drugs come off patent by
year-end 2007. Since PBMs typically receive a portion of the savings they
achieve for customers, the potentially higher market share of cheaper generics
should leverage earnings.

Finally, in spite of their exceptional performance, homebuilder stocks continue
to be priced as if the housing industry is about to collapse. For example,
Centex is trading at approximately 7 times 2005 earnings forecasts and Lennar
Corp is trading at 8 times next year's profit estimates, compared to the S&P
500's multiple of 16 as of fiscal year end. This is too big a discount for high
quality companies in what should continue to be a very profitable business.

Looking ahead to 2005, we believe that barring a major terrorist event and/or a
big spike in oil prices, the economy will settle into sustainable moderate


                                       1


Partners Portfolio Manager's Commentary cont'd

growth with modest inflation. This should translate into profit growth that
equals or exceeds current consensus estimates. Of course, we maintain our
belief that disciplined investors buying high quality companies trading at
below market multiples can outperform the broad-based stock market indices over
the long term.

Sincerely,

/s/ S. BASU MULLICK

             1. 18.98%, 3.59% and 11.97% were the average annual total returns
                for the 1-, 5- and 10-year periods ended December 31, 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. The performance information does
                not reflect fees and expenses of the insurance companies.


             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 the 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 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.

investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:

                                                        ratio and an assumed

                                                        year before expenses.
                                                        This return is not the

                                                        expenses you paid for
                                                        the period. You may use

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

Notes to Schedule of Investments Partners Portfolio

+    Investments in equity securities by Neuberger Berman Advisers Management
     Trust Partners Portfolio (the "Fund") are valued at the latest sale 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 and 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 noon, 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. When changes in the
     value of a certain index suggest that the closing prices on the foreign
     exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income tax
     purposes was $560,911,172. Gross unrealized appreciation of investments was
     $129,574,530 and gross unrealized depreciation of investments was
     $2,967,773, resulting in net unrealized appreciation of $126,606,757, based
     on cost for U.S. Federal income tax purposes.

*    Non-income producing security.

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

@    Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
     Neuberger Berman Management Inc. (see Notes A & F of Notes to Financial
     Statements) and may be considered an affiliate since it has the same
     officers, Board members, and investment manager as the Fund and because, at
     times, the Fund may own 5% or more of the outstanding voting securities of
     Prime Money.

++   The N&B Securities Lending Quality Fund, LLC ("Quality Fund") is an
     investment vehicle established by the Fund's custodian to invest cash the
     Fund receives as collateral for securities loans. The Fund's shares in the
     Quality Fund are non-voting. However, because all shares of the Quality
     Fund are held by funds in the related investment management complex, the
     Quality Fund may be considered an affiliate of the Fund (see Notes A & F of
     Notes to Financial Statements).

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004



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 eleven 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 (the "Board") 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 U.S. generally
     accepted accounting principles 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 noon, 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, if any, 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
     year ended December 31, 2004 was $726,010.


5    Income tax information: 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
     requirements of Subchapter M of the Internal Revenue Code applicable to
     regulated


                                       11


Notes to Financial Statements Partners Portfolio cont'd

     investment companies and to distribute substantially all of its earnings to
     its shareholders. Therefore, no Federal income or excise tax provision is
     required.


     Income dividends and capital gain distributions are determined in
     accordance with income tax regulations, which may differ from generally
     accepted accounting principles. These differences are primarily due to
     differing treatments of income and gains on various investment securities
     held by the Fund, timing differences and differing characterization of
     distributions made by the Fund as a whole. The Fund may also utilize
     earnings and profits distributed to shareholders on redemption of shares as
     a part of the dividends paid deduction for income tax purposes.

     As determined on December 31, 2004, permanent differences resulting
     primarily from different book and tax accounting for foreign currency gains
     and losses were reclassified at year end. These reclassifications had no
     effect on net income, net assets or net assets per share of the Fund.

     The tax character of distributions paid during the years ended December 31,
     2004 and December 31, 2003 were as follows:

     Distributions Paid From:



                                Long-Term        Tax Return
         Ordinary Income      Capital Gain       of Capital             Total
             2004     2003     2004     2003     2004     2003         2004      2003
                                                         
        $62,733      $  -     $  -     $  -     $  -     $  -     $62,733      $  -


     As of December 31, 2004, 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
                                                             
     $6,485,081          $147,586       $126,616,206              $  -    $133,248,873


     The difference between book basis and tax basis distributable earnings is
     attributable primarily to timing differences on wash sales.

     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. During the year ended December 31, 2004, the Fund
     utilized capital loss carryforwards of $102,078,848.

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.

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


                                       12


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     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    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   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 Board, 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
     ("Quality Fund"), which is managed by State Street Bank and Trust Company
     ("State Street") pursuant to guidelines approved by the Trust's investment
     manager. Neuberger guaranteed a certain amount of 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 as of July 1, 2004
     with substantially the same terms. Under this current Agreement, Neuberger
     guarantees a certain amount of revenue to the Fund and receives any revenue
     earned in excess of the guaranteed amount as a lending agency fee. For the
     year ended December 31, 2004, Neuberger received $77,865 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-affiliated issuer.

     In February of 2005, it is likely that the Fund will change the collateral
     investment vehicle from the Quality Fund, managed by State Street, to a
     fund managed by Lincoln Capital, an affiliate, as approved by the Board.


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") and the Neuberger Berman Prime Money

     Fund ("Prime Money"), affiliated funds, which are managed by Management and
     have the same Board members as the Fund. The Cash Fund and Prime Money each
     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 or Prime Money, Management waives a
     portion of its management fee equal to the management fee it receives from
     the Cash Fund or Prime Money on those assets. For the year ended December
     31, 2004, such waived fees amounted to $12,665 and $71 for the Cash Fund
     and Prime Money, respectively. For the year ended December 31, 2004, income
     earned on the investments of the Cash Fund and Prime Money amounted to
     $124,986 and $1,672, respectively, and is reflected in the Statement of
     Operations under the caption Income from investments in affiliated issuers.


12   Indemnifications: Like many other companies, the Trust's organizational
     documents provide that its officers and trustees are indemnified against
     certain liabilities arising out of the performance of their duties to the
     Trust. In addition, both in some of its principal service contracts and in
     the normal course of its business, the Trust enters into contracts that
     provide indemnifications to other parties for certain types of losses or
     liabilities. The Trust's maximum exposure under these arrangements is
     unknown as this could involve future claims against the Trust.


     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 this agreement.

     The Board adopted a non-fee distribution plan for the Fund.

     Management has contractually undertaken through December 31, 2008 to
     reimburse the Fund for its operating expenses (excluding 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 the Fund's average daily net assets (the
     "Expense Limitation"). For the year ended December 31, 2004, no
     reimbursement to the Fund was required. The Fund has agreed to repay
     Management through December 31, 2011 for its excess Operating Expenses
     previously reimbursed by

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     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 year ended December 31, 2004, there was no reimbursement to Management
     under this agreement. At December 31, 2004, the Fund has no contingent
     liability to Management under this 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 year ended
     December 31, 2004, the impact of this arrangement was a reduction of
     expenses of $96,866.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. For the year ended December 31, 2004, the impact of this
     arrangement was a reduction of expenses of $320.


     Note C--Securities Transactions:

     During the year ended December 31, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $432,697,248 and
     $601,508,647, respectively.

     During the year ended December 31, 2004, brokerage commissions on
     securities transactions amounted to $1,443,750, of which Neuberger received
     $10, Lehman received $274,479, and other brokers received $1,169,261.

     Note E--Line of Credit:

     At December 31, 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 all or any part of the
     $150,000,000 at any particular time. The Fund had no loans outstanding
     pursuant to this line of credit at December 31, 2004, nor had the Fund
     utilized this line of credit at any time prior to that date.

     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.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Partners Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Partners Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as
of December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian and brokers or other
appropriate auditing procedures where replies from brokers were not received.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Partners Portfolio of Neuberger Berman Advisers Management Trust at December
31, 2004, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended, and its
financial highlights for each of the five years in the period then ended, in
conformity with U.S. generally accepted accounting principles.

Regency Portfolio Manager's Commentary
- --------------------------------------

Mid-cap value stocks were in the market's sweet spot in 2004, as the Russell
Midcap Value Index outperformed other major domestic equity indices as tracked
by Russell. The Neuberger Berman AMT Regency Portfolio provided strong returns
for the period, slightly trailing this top performing benchmark.(2)

Consumer Discretionary investments provided the greatest contribution to the
portfolio's absolute returns, with toolmaker Black & Decker among our top
performers. Financial holdings also helped results, with regional bank Charter
One Financial and investment banker/broker Bear Stearns providing substantial
returns. The Energy sector also augmented total returns, with natural gas
production company XTO Energy and refiner/ gasoline retailer/chemicals producer
Sunoco delivering our best stock performances. Health Care investments, most
notably HMOs WellPoint (formerly Anthem), Oxford Health Plans (acquired by
UnitedHealth Group) and Wellchoice, had a favorable impact on returns relative
to the benchmark, with our holdings more than tripling benchmark component
returns.

Although we still see some opportunities in Energy and Health Care, our
valuation discipline has prompted us to reduce our exposure in both. We began
accumulating Energy stocks because we believed they were inexpensive relative
to earnings potential. However, the Energy group has performed so well that
most of its stocks now appear fairly valued. At year's end, our Energy
portfolio included just three names--XTO Energy, Sunoco, and Pioneer Natural
Resources--which we think are bargains even if energy prices decline. We have
reduced our Health Care exposure as well. At mid-year, economic growth was
slowing and investors returned to this and other less economically sensitive
industries. As a result, several of our Health Care holdings, such as Davita,
an operator of kidney dialysis centers, appreciated and were sold. Although we
continue to like select Health Care stocks, we are not finding as much value as
we were a year ago.

Our Industrial holdings were poor performers in 2004, largely due to the sharp
decline of one stock, diversified manufacturer SPX Corp. SPX experienced
operational problems, the worst being its inability to pass on spiraling raw
material costs to customers. While SPX's issues are not trivial, we think that
the new CEO will be able to fix them, and we applaud his strategy of shedding
assets in a "seller's market" for industrial businesses. We plan to be patient
with SPX and hope to capitalize on the turnaround we anticipate in the years
ahead.

Relative to the benchmark, portfolio results were restrained more by what we
didn't own than by what we did. For example, although Real Estate Investment
Trusts (REITs) comprise about 9% of the benchmark, we don't own any of these
strongly performing stocks, since we consider them to be a separate asset
class. We also did not own any Materials stocks, which also did well, since the
group contains very few attractively valued companies that meet our quality
standards. While we missed the run-up in Materials stocks this year, we also
expect to miss the inevitable sell-off.

We think that the portfolio's strong results in 2004 are a testament to the
benefits of bottom-up stock picking. To wit, the composition of our top-ten
performance list had little correlation with the market sectors that posted the
strongest performance. Although our two best performers came from the red-hot
energy sector, the balance of our top ten included three HMOs, a tool company,
a beverage company, a regional bank, an auto parts maker, and an investment
bank/broker.

Looking forward, we think that the economy will grow this year and that
corporate earnings will be good, but uninspiring. We do not see convincing

                                       1

reasons for stocks to go up or down significantly. Even if we did, however, we
do not spend much time focusing on macroeconomics. Instead, we devote our
energy to looking for high-quality companies trading at opportunistic
prices--in our view the best way to achieve superior risk-adjusted investment
returns over the long term.

Sincerely,

               1.   22.36% and 12.41% were the average annual total returns for
                    the 1-year and since inception (08/22/01) periods ended
                    December 31, 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. The
                    performance information does not reflect fees and expenses
                    of the insurance companies.

               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 26% 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 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.

Information About Your Fund's Expenses
- --------------------------------------

This table is designed to provide information regarding costs related to your
investments. All mutual funds incur operating expenses, which include
management fees, administrative services and shareholder reports among others.
The following example is based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period. The table illustrates the
fund's costs in two ways:




                                        
                             Actual Expenses:  The first section of the table provides
                                               information about actual account values and actual
                                               expenses in dollars. You may use the information
                                               in this line, together with the amount you
                                               invested, to estimate the expenses you paid over
                                               the period.


Hypothetical Example for Comparison Purposes:  The second section of the  table provides
                                               information  about hypothetical account values and
                                               hypothetical expenses based on the Fund's actual
                                               expense ratio and an assumed rate of return at
                                               5% per year before expenses. This return is not the
                                               Fund's actual return. The hypothetical account values
                                               andexpenses may not be used to estimate the actual
                                               ending account balance or expenses you paid for the
                                               period. You may use this information to compare the
                                               ongoing costs of investing in this Fund versus other
                                               funds. To do so, compare this 5% hypothetical example
                                               with the 5%hypothetical examples that appear in the
                                               shareholder reports of otherfunds.

     *    Expenses are equal to the expense ratio for the class, multiplied by
          the average account value over the period, multiplied by 184/366 (to
          reflect the one-half year period shown).

     **   Hypothetical 5% annual return before expenses is calculated by
          multiplying the number of days in the most recent half year divided by
          366.

Notes to Schedule of Investments Regency Portfolio
- --------------------------------------------------

+    Investments in equity securities by Neuberger Berman Advisers Management
     Trust Regency Portfolio (the "Fund") are valued at the latest sale 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 and 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 noon, 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. When changes in the
     value of a certain index suggest that the closing prices on the foreign
     exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income tax
     purposes was $145,504,687. Gross unrealized appreciation of investments was
     $17,757,363 and gross unrealized depreciation of investments was $188,978,
     resulting in net unrealized appreciation of $17,568,385, based on cost for
     U.S. Federal income tax purposes.

*    Non-income producing security.

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

@    Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
     Neuberger Berman Management Inc. (see Notes A & F of Notes to Financial
     Statements) and may be considered an affiliate since it has the same
     officers, Board members, and investment manager as the Fund and because, at
     times, the Fund may own 5% or more of the outstanding voting securities of
     Prime Money.

++   The N&B Securities Lending Quality Fund, LLC ("Quality Fund") is an
     investment vehicle established by the Fund's custodian to invest cash the
     Fund receives as collateral for securities loans. The Fund's shares in the
     Quality Fund are non-voting. However, because all shares of the Quality
     Fund are held by funds in the related investment management complex, the
     Quality Fund may be considered an affiliate of the Fund (see Notes A & F of
     Notes to Financial Statements).

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 eleven 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 (the
               "Board") 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 U.S.
               generally accepted accounting principles 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
               noon, 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, if any, are recorded on the basis of identified
               cost and stated separately in the Statement of Operations.

          5    Income tax information: 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 requirements of Subchapter M of the
               Internal Revenue Code applicable to regulated investment
               companies and to distribute substantially all of its earnings to
               its shareholders. Therefore, no Federal income or excise tax
               provision is required.

                                       10



                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004



     Income dividends and capital gain distributions are determined in
     accordance with income tax regulations, which may differ from generally
     accepted accounting principles. These differences are primarily due to
     differing treatments of income and gains on various investment securities
     held by the Fund, timing differences and differing characterization of
     distributions made by the Fund as a whole. The Fund may also utilize
     earnings and profits distributed to shareholders on redemption of shares as
     a part of the dividends paid deduction for income tax purposes.

     As determined on December 31, 2004, permanent differences resulting
     primarily from different book and tax accounting for foreign currency gains
     and losses were reclassified at year end. These reclassifications had no
     effect on net income, net assets or net assets per share of the Fund.

     The tax character of distributions paid during the years ended December 31,
     2004 and December 31, 2003 were as follows:



Distributions Paid From:

                             Ordinary Income    Tax Return of Capital        Total
                               2004     2003        2004     2003         2004    2003
                                                                 
                            $27,438       $-          $-       $-      $27,438      $-


     As of December 31, 2004, 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
                                                                    
            $4,449,542        $8,209,001        $17,568,385            $-          $30,226,928


     The difference between book basis and tax basis distributable earnings is
     attributable primarily to timing differences of wash sales.

     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. During the year ended December 31, 2004, the Fund
     utilized capital loss carryforwards of $65,315.

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.

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.

                                       11

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

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 Board, 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
     ("Quality Fund"), which is managed by State Street Bank and Trust Company
     ("State Street") pursuant to guidelines approved by the Trust's investment
     manager. Neuberger guaranteed a certain amount of 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 as of July 1, 2004
     with substantially the same terms. Under this current Agreement, Neuberger
     guarantees a certain amount of revenue to the Fund and receives any revenue
     earned in excess of the guaranteed amount as a lending agency fee. For the
     year ended December 31, 2004, Neuberger received $10,765 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-affiliated issuer.

     In February of 2005, it is likely that the Fund will change the collateral
     investment vehicle from the Quality Fund, managed by State Street, to a
     fund managed by Lincoln Capital, an affiliate, as approved by the Board.

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") and the Neuberger Berman Prime Money Fund ("Prime
     Money"), affiliated funds, which are managed by Management and have the
     same Board members as the Fund. The Cash Fund and Prime Money each 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 or Prime Money, Management waives a
     portion of its management fee equal to the management fee it receives from
     the Cash Fund or Prime Money on those assets. For the year ended December
     31, 2004, management fees waived amounted to $4,000 and $60 for the Cash
     Fund and Prime Money, respectively. For the year ended December 31, 2004,
     income earned on the investments of

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     the Cash Fund and Prime Money amounted to $45,933 and $1,401, respectively,
     and is reflected in the Statement of Operations under the caption Income
     from investments in affiliated issuers.

12   Indemnifications: Like many other companies, the Trust's organizational
     documents provide that its officers and trustees are indemnified against
     certain liabilities arising out of the performance of their duties to the
     Trust. In addition, both in some of its principal service contracts and in
     the normal course of its business, the Trust enters into contracts that
     provide indemnifications to other parties for certain types of losses or
     liabilities. The Trust's maximum exposure under these arrangements is
     unknown as this could involve future claims against the Trust.


     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 this agreement.

     The Board adopted a non-fee distribution plan for the Fund.

     Management has contractually undertaken through December 31, 2008 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 the Fund's average daily net
     assets (the "Expense Limitation"). For the year ended December 31, 2004, no
     reimbursement to the Fund was required. The Fund has agreed to repay
     Management through December 31, 2011 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 year ended December 31, 2004, there
     was no reimbursement to Management under this agreement. At December 31,
     2004, the Fund has no contingent liability to Management under this
     agreement.

                                       13

     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 year ended
     December 31, 2004, the impact of this arrangement was a reduction of
     expenses of $14,584.

     The Fund has an expense offset arrangement in connection with its custodian
     contract. For the year ended December 31, 2004, the impact of this
     arrangement was a reduction of expenses of $326.


     Note C--Securities Transactions:

     During the year ended December 31, 2004, there were purchase and sale
     transactions (excluding short-term securities) of $116,985,606 and
     $60,794,331, respectively.

     During the year ended December 31, 2004, brokerage commissions on
     securities transactions amounted to $243,004, of which Neuberger received
     $95, Lehman received $44,878, and other brokers received $198,031.


     Note D--Fund Share Transactions:

     Share activity for the years ended December 31, 2004 and December 31, 2003
     was as follows:

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

     Note E--Line of Credit:

     At December 31, 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 all or any part of the
     $150,000,000 at any particular time. The Fund had no loans outstanding
     pursuant to this line of credit at December 31, 2004, nor had the Fund
     utilized this line of credit at any time prior to that date.

++   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

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Regency Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Regency Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as
of December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of periods indicated
therein. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian and brokers or other
appropriate auditing procedures where replies from brokers were not received.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Regency Portfolio of Neuberger Berman Advisers Management Trust at December 31,
2004, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and its
financial highlights for each of the periods indicated therein, in conformity
with U.S. generally accepted accounting principles.

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

Through much of 2004, investors focused on the negatives (Federal Reserve rate
hikes, high oil prices, Iraq, and divisive political rhetoric) instead of the
positives (a healthy economy and strong corporate earnings growth). Then, in
late October investor sentiment abruptly changed. Stocks took off and the
broad-based market indices closed the year with respectable gains. For the year,
the Neuberger Berman AMT Socially Responsive Portfolio outperformed the S&P 500,
but trailed the Russell 1000 Value Index.2

Energy sector holdings had a positive impact on the portfolio's absolute
returns, with exploration and production companies Newfield Exploration and
Cimarex Energy heading our top-ten performance list. Health Care investments
also contributed to returns, with managed care bellwether UnitedHealth Group and
laboratory testing company Quest Diagnostics providing impressive results.
Industrial stocks, including Canadian National Railway and diversified
manufacturer Danaher Group, also excelled. However, Information Technology
holdings including Teradyne, Synopsys, National Instruments and Altera were a
drag on returns.

Our investment approach was evident in 2004, as we reduced our overweight in
Energy, the market's single best performing sector, and increased our exposure
to Information Technology (IT), one of the weaker sectors. We have been cutting
our Energy commitment because we believe that oil and natural gas prices could
weaken more than is generally anticipated. In 2004, energy prices soared as
demand increased due to strong global economic growth and supply disruptions in
Iraq, Venezuela, and the U.S. Japan is reducing its oil dependency by reopening
nuclear plants, and China has three major coal-powered generating plants coming
on line in 2005. Also, drilling activity has finally picked up. Barring
unforeseen events, supply and demand for energy should come into better balance.
As a result, we thought it prudent to sell into strength, and we now have a near
neutral weighting in Energy versus the S&P 500.

In contrast to Energy, the IT sector is once again viewed with dismay by
investors. The perception is that after an exceptional 2003, tech stocks are
once again overpriced and ready for a fall. We disagree. Let's consider the
semiconductor and semiconductor equipment stocks, which declined sharply when
the economy stalled this summer, leaving chip makers with excess inventory. We
believe that this inventory imbalance has largely been worked off due to strong
end-market demand and we note that Intel has announced that it expects wafer
starts to increase in first quarter 2005. If this proves to be an industry-wide
phenomenon, revenues should recover quickly. With the enormous operating
leverage in this business, 2005 earnings could be considerably better than Wall
Street is expecting.

As is our custom, we will detail a portfolio holding that both demonstrates our
investment discipline and is a good corporate citizen. Canadian National Railway
is the most efficient railroad in North America, and is favored by a number of
important developments. For example, as manufacturing continues to move
overseas, the demand for long haul shipping (from the coasts to the heartland)
is likely to increase, helping the railroads. In the shorter term, their
relatively low fuel costs should help railroads gain market share from truckers
vulnerable to currently high energy prices. In addition, Canadian National has
steadily invested in its infrastructure, and has been able to handle increased
demand with few problems, giving it a further pricing advantage. Despite the
stock's excellent performance this year, however, we think there is plenty more
upside. From a socially responsible perspective, we consider railroads
environmentally friendly because they are nearly four times more fuel efficient
than trucks. And Canadian National continues to upgrade its

                                        1

     1.   13.28%, 4.25% and 6.16% were the average annual total returns for the
          1-year, 5-year and since inception (02/18/99) periods ended December
          31, 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. The
          performance information does not reflect fees and expenses of the
          insurance companies.

     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 directly 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 Socially Responsive Portfolio
- --------------------------------------------------------------

+    Investments in equity securities by Neuberger Berman Advisers Management
     Trust Socially Responsive Portfolio (the "Fund") are valued at the latest
     sale 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 and 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 noon, 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. When changes in the
     value of a certain index suggest that the closing prices on the foreign
     exchanges may 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 December 31, 2004, the cost of investments for U.S. Federal income tax
     purposes was $19,113,035. Gross unrealized appreciation of investments was
     $3,201,177 and gross unrealized depreciation of investments was $3,065,
     resulting in net unrealized appreciation of $3,198,112, based on cost for
     U.S. Federal income tax purposes.

*    Non-income producing security.

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

++   The N&B Securities Lending Quality Fund, LLC ("Quality Fund") is an
     investment vehicle established by the Fund's custodian to invest cash the
     Fund receives as collateral for securities loans. The Fund's shares in the
     Quality Fund are non-voting. However, because all shares of the Quality
     Fund are held by funds in the related investment management complex, the
     Quality Fund may be considered an affiliate of the Fund (see Notes A & F of
     Notes to Financial Statements).

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
          eleven 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 (the "Board") 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 U.S.
          generally accepted accounting principles 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 noon, 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, if any, are recorded on the basis of identified cost and
          stated separately in the Statement of Operations.

     5    Income tax information: 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 requirements of Subchapter M of the Internal Revenue Code
          applicable to regulated investment companies and to distribute
          substantially all of its earnings to its shareholders. Therefore, no
          Federal income or excise tax provision is required.

                                       10


                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

          Income dividends and capital gain distributions are determined in
          accordance with income tax regulations, which may differ from
          generally accepted accounting principles. These differences are
          primarily due to differing treatments of income and gains on various
          investment securities held by the Fund, timing differences and
          differing characterization of distributions made by the Fund as a
          whole. The Fund may also utilize earnings and profits distributed to
          shareholders on redemption of shares as a part of the dividends paid
          deduction for income tax purposes.

          As determined on December 31, 2004, permanent differences resulting
          primarily from different book and tax accounting for distributions
          from real estate investment trusts, net operating losses and foreign
          currency gains and losses, were reclassified at year end. These
          reclassifications had no effect on net income, net assets or net
          assets per share of the Fund.

          As of December 31, 2004, 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    Loss Carryforwards
        Income              Gain     (Depreciation)         and Deferrals         Total
                                                                 
          $  -           $93,081         $3,198,101              $(6,797)    $3,284,385


          The difference between book basis and tax basis distributable earnings
          is attributable primarily to timing differences on wash sales, return
          of capital distributions from real estate investment trusts, and
          post-October losses.

          Under current tax law, certain net capital and net foreign currency
          losses realized after October 31, 2004 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, 2004, the fund elected to
          defer $6,797 net capital losses arising between November 1, 2004 and
          December 31, 2004.

          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.

     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.

     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

          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 Board, 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 ("Quality Fund"), which is managed by State Street
          Bank and Trust Company ("State Street") pursuant to guidelines
          approved by the Trust's investment manager. Neuberger guaranteed a
          certain amount of 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 as of July 1,
          2004 with substantially the same terms. Under this current Agreement,
          Neuberger guarantees a certain amount of revenue to the Fund and
          receives any revenue earned in excess of the guaranteed amount as a
          lending agency fee. For the year ended December 31, 2004, Neuberger
          received $202 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-affiliated issuer.

          In February of 2005, it is likely that the Fund will change the
          collateral investment vehicle from the Quality Fund, managed by State
          Street, to a fund managed by Lincoln Capital, an affiliate, as
          approved by the Board.

     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   Indemnifications: Like many other companies, the Trust's
          organizational documents provide that its officers and trustees are
          indemnified against certain liabilities arising out of the performance
          of their duties to the Trust. In addition, both in some of its
          principal service contracts and in the normal course of its business,
          the Trust enters into contracts that provide indemnifications to other
          parties for certain types of losses or liabilities. The Trust's
          maximum exposure under these arrangements is unknown as this could
          involve future claims against the Trust.

                    NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2004

          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 this
          agreement.

          The Board adopted a non-fee distribution plan for the Fund.

          Management has contractually undertaken through December 31, 2008 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 the Fund's 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 year ended December 31, 2004, such excess expenses amounted to
          $54,057. The Fund has agreed to repay Management through December 31,
          2011 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 year ended December 31, 2004, there was no
          reimbursement to Management under this agreement. At December 31,
          2004, contingent liabilities to Management under this agreement were
          as follows:



         Expiring in
                2005         2006         2007         Total
                                           
             $54,400      $57,506      $54,057      $165,963



          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
          year ended December 31, 2004, the impact of this arrangement was a
          reduction of expenses of $1,269.

          The Fund has an expense offset arrangement in connection with its
          custodian contract. For the year ended December 31, 2004, the impact
          of this arrangement was a reduction of expenses of $29.

          Note C--Securities Transactions:

          During the year ended December 31, 2004, there were purchase and sale
          transactions (excluding short-term securities) of $11,641,963 and
          $2,490,359, respectively.

          During the year ended December 31, 2004, brokerage commissions on
          securities transactions amounted to $18,896, of which Neuberger
          received $0, Lehman received $3,946, and other brokers received
          $14,950.

          Note D--Fund Share Transactions:

          Share activity for the years ended December 31, 2004 and December 31,
          2003 was as follows:



                                     For the Year Ended December 31,
                                2004                                2003

          Note E--Line of Credit:

          At December 31, 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 all or any part of the $150,000,000 at
          any particular time. The Fund had no loans outstanding pursuant to
          this line of credit at December 31, 2004, nor had the Fund utilized
          this line of credit at any time prior to that date.

    +     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

Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------

To the Board of Trustees of
Neuberger Berman Advisers Management Trust and
Shareholders of Socially Responsive Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Socially Responsive Portfolio, one of the series
constituting the Neuberger Berman Advisers Management Trust (the "Trust"), as of
December 31, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements and financial highlights. Our procedures
included confirmation of securities owned as of December 31, 2004, by
correspondence with the custodian and brokers or other appropriate auditing
procedures where replies from brokers were not received. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Socially Responsive Portfolio of Neuberger Berman Advisers Management Trust at
December 31, 2004, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and its financial highlights for each of the five years in the period then
ended, in conformity with U.S. generally accepted accounting principles.

(e)(1) The Audit Committee's pre-approval policies and procedures for the
Registrant to engage an accountant to render audit and non-audit services
delegate to the Chair of the Audit Committee the power to pre-approve services
between meetings of the Audit Committee.

respectively, for E&Y, and $2,500 and $0, respectively, for Tait
Weller.

         over financial reporting (as defined in rule 30a-3(d) under the Act)
