Energy was the best performing equity sector, reflecting record highs in crude oil prices due to increased Asian demand and a strong U.S. economy. Sectors tied to the consumer were generally the weakest, as personal income was squeezed by higher energy costs and higher interest rates. For the year, the equity portion of the Neuberger Berman Advisers Management Trust (AMT) Balanced Portfolio generated a positive return. Financial and Energy holdings were significant contributors to the Portfolio's equity performance. Within Financials, stocks that did well included business services companies and brokerage firms. Stock selection within Health Care also benefited returns. Holdings in the Consumer Staples sector were also additive. In aggregate, sector allocation contributed to performance, with Portfolio overweights in Telecom and Energy--two of 2005's best performing sectors--providing much of the value added. Stock selection within Information Technology had the most negative impact on the equity segment's relative performance. Within this sector, various software companies showed weakness, while some business services companies also underperformed. Like the equity markets, the fixed income markets were focused on the Federal Reserve during 2005. Over the course of the year, long rates did not rise as much as they have historically during Fed tightening campaigns. In fact, the U.S. Treasury yield curve inverted at year-end, meaning that long-term bonds provided smaller yields than short-term bonds. The difference was slight, but the inversion is significant as it marks the first time this has happened since 2000. The fixed income component of the Portfolio generated a modestly positive return for 2005. Throughout the year, we maintained a defensive posture in this segment, restraining the overall duration (a standard measure of the sensitivity of a bond's price to interest rate movements) of our holdings. During the year, we made opportunistic changes to sector allocation in order to enhance yield. We substantially reduced our allocation to Treasuries, reinvesting the proceeds in higher yielding alternatives. We significantly increased our allocation to AAA-rated asset-backed and mortgage-backed securities with well-defined maturities. Given the current economic environment, we decreased our allocation to BBB-rated securities, so that by fiscal year-end, much of the fixed income segment of the Portfolio was in AAA securities. Looking ahead, we are encouraged that at its December meeting, the Fed removed the reference to "accommodative" from its policy statement, and indicated that it is getting closer to the end of its tightening campaign. Domestic consumers, however, remain financially stretched. Real wage growth has been non-existent this economic cycle. Instead, consumer spending has been driven by strong housing gains and additional debt. Housing now contributes over 6% of GDP and is showing signs of slowing. We do not expect a housing price collapse, but this major support for U. S. consumer spending is weakening, which could slow economic activity. In contrast, 1 <Page> foreign economies in Asia, Japan and even Europe are exhibiting increased economic activity. Therefore, we currently plan to tilt the equity segment of the Portfolio toward beneficiaries of global economic expansion and corporate spending and away from exposure to the beleaguered American consumer. As for our fixed income investments, we will remain conservative from a duration standpoint, until we have clearer direction from the Fed. Sincerely, /s/ Ted Giuliano /s/ John Dugenske /s/ Jon D.

The Russell Midcap(R) Growth Index measures the performance of those Russell Midcap(R) 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(R) 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. 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 we 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 certain qualified pension and retirement plans.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION AS OF 12/31/05 (UNAUDITED) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST BALANCED PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS I $ 1,000 $ 1,077.30 $ 5.92 HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** CLASS I $ 1,000 $ 1,019.51 $ 5.75 </Table> * Expenses are equal to the expense ratio for the class, multiplied by the average account value over the period, multiplied by 184/365 (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 365. 4 <Page> SCHEDULE OF INVESTMENTS BALANCED PORTFOLIO <Table> <Caption> NUMBER OF SHARES MARKET VALUE + COMMON STOCKS (69.1%) AEROSPACE (1.4%) 8,000 Precision Castparts $ 414,480 13,500 Rockwell Collins 627,345 ------------ 1,041,825 BASIC MATERIALS (1.6%) 17,000 Airgas, Inc. 559,300 7,500 Peabody Energy 618,150 ------------ 1,177,450 BIOTECHNOLOGY (3.3%) 15,500 Celgene Corp. 1,004,400* 14,500 Gilead Sciences 763,135* 6,000 Invitrogen Corp. 399,840* 4,500 Protein Design Labs 127,890* 6,250 Vertex Pharmaceuticals 172,938* ------------ 2,468,203 BUSINESS SERVICES (5.7%) 17,000 Alliance Data Systems 605,200* 13,200 CB Richard Ellis Group 776,820* 13,050 Corporate Executive Board 1,170,585 8,150 Getty Images 727,550* 3,000 Iron Mountain 126,660* 13,500 Monster Worldwide 551,070* 5,900 NAVTEQ 258,833* ------------ 4,216,718 BUSINESS SERVICES--IT BUSINESS SERVICES (0.4%) 4,500 DST Systems 269,595* COMMUNICATIONS EQUIPMENT (1.5%) 6,500 ADC Telecommunications 145,210* 6,000 Harris Corp. 258,060 21,000 Juniper Networks 468,300* 19,000 Tellabs, Inc. 207,100* ------------ 1,078,670 CONSUMER CYCLICALS (0.2%) 3,200 Williams-Sonoma 138,080* CONSUMER DISCRETIONARY (3.0%) 13,500 Advance Auto Parts 586,710* 6,100 Fortune Brands 475,922 6,000 Harman International Industries 587,100 5,500 Laureate Education 288,805* 10,500 XM Satellite Radio Holdings 286,440* ------------ 2,224,977 CONSUMER STAPLES (1.4%) 11,500 Shoppers Drug Mart 433,784 7,400 Whole Foods Market 572,686 ------------ 1,006,470 DIAGNOSTIC EQUIPMENT (1.2%) 26,700 Cytyc Corp. 753,741* 2,000 IDEXX Laboratories 143,960* ------------ 897,701 DISTRIBUTOR (0.7%) 7,500 W.W.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $58,282,873. Gross unrealized appreciation of investments was $16,945,904 and gross unrealized depreciation of investments was $780,865, resulting in net unrealized appreciation of $16,165,039 based on cost for U.S. Federal income tax purposes. * Non-income producing security. ** Restricted security subject to restrictions on resale under federal securities laws. 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, 2005, these securities amounted to $910,661 or 1.2% of net assets for the Fund. *** Floating rate securities are securities whose yields vary with a designated market index or market rate. These securities are shown at their current rates as of December 31, 2005. ^^ All or a portion of this security is on loan (see Note A of Notes to Financial Statements).

The Trust is currently comprised of twelve 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, 2005 was $208. 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 15 <Page> between the original contract price and the closing price of such contract is included in net realized gains or losses on foreign currency transactions on settlement date. Fluctuations in the value of forward foreign currency contracts are recorded for financial reporting purposes as unrealized gains or losses by the Fund until the contractual settlement date. 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 distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, permanent differences resulting primarily from different book and tax accounting for foreign currency gains and losses, paydown gains and losses, and amortization of bond premium, 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, 2005 and December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME TOTAL 2005 2004 2005 2004 $ 711,567 $ 989,988 $ 711,567 $ 989,988 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNREALIZED LOSS UNDISTRIBUTED APPRECIATION CARRYFORWARDS ORDINARY INCOME (DEPRECIATION) AND DEFERRALS TOTAL $ 585,557 $ 16,164,776 $ (37,021,077) $ (20,270,744) </Table> 16 <Page> 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, 2005, the Fund had unused capital loss carryforwards available for Federal income tax purposes to offset net realized capital gains, if any, as follows: <Table> <Caption> EXPIRING IN: 2009 2010 $ 23,287,066 $ 13,734,011 </Table> During the year ended December 31, 2005, the Fund utilized capital loss carryforwards of $3,180,628. 7 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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 17 <Page> 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, possibly at a time of rapidly declining prices, and/or a change in the value of the contract may not correlate with changes in the value of the underlying securities. For U.S. Federal income tax purposes, the futures transactions undertaken by the Fund may cause the Fund to recognize gains or losses from marking to market even though its positions have not been sold or terminated, may affect the character of the gains or losses recognized as long-term or short-term, and may affect the timing of some capital gains and losses realized by the Fund. Also, the Fund's losses on transactions involving futures contracts may be deferred rather than being taken into account currently in calculating the Fund's taxable income. During the year ended December 31, 2005, the Fund did not enter into any financial futures contracts. 11 SECURITY LENDING: Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund entered into a Securities Lending Agreement ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $3,047. Effective September 13, 2005, the Fund entered into new securities lending arrangements using a third party, eSecLending, to secure bids. Pursuant to such arrangements, eSecLending currently acts as agent for the Fund arranging principals to guarantee a certain amount of revenue to the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income from the lending program represents income earned on the cash collateral and the guaranteed amount, less fees and expenses associated with the loans. These amounts are reflected in the Statement of Operations under the caption "Income from securities loaned (affiliated issuers)." 12 REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements with institutions that Management 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. 18 <Page> 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $358 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $11,574 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. 19 <Page> 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, 2005, 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, 2005, there was no reimbursement to Management under this agreement. At December 31, 2005, the Fund has no contingent liability to Management under this agreement. Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $6,603. The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $1,288. 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, 2005 were as follows: <Table> <Caption> SALES AND MATURITIES PURCHASES OF PURCHASES EXCLUDING SALES AND MATURITIES EXCLUDING U.S. GOVERNMENT U.S. GOVERNMENT OF U.S. GOVERNMENT U.S. GOVERNMENT AND AND AGENCY AND AGENCY AND AGENCY AGENCY OBLIGATIONS OBLIGATIONS OBLIGATIONS OBLIGATIONS $ 16,889,861 $ 44,276,481 $ 24,452,393 $ 49,747,946 </Table> 20 <Page> During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $84,629, of which Neuberger received $141, Lehman received $13,173, and other brokers received $71,315. During the year ended December 31, 2005, the Fund entered into various contracts to deliver currencies at specified future dates.

Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit. 21 <Page> NOTE F--INVESTMENTS IN AFFILIATES*: <Table> <Caption> INCOME FROM INVESTMENTS BALANCE OF BALANCE OF IN SHARES GROSS SHARES AFFILIATED HELD GROSS SALES HELD VALUE ISSUERS DECEMBER 31, PURCHASES AND DECEMBER 31, DECEMBER 31, INCLUDED IN NAME OF ISSUER 2004 AND ADDITIONS REDUCTIONS 2005 2005 TOTAL INCOME Neuberger Berman Securities Lending Quality Fund, LLC** 2,965,200 86,957,848 89,274,447 648,601 $ 648,601 $ 15,399 Neuberger Berman Prime Money Fund Trust Class*** 368,172 17,764,567 18,039,744 92,995 92,995 11,574 ------------ ------------ TOTAL $ 741,596 $ 26,973 ============ ============ </Table> * Affiliated issuers, as defined in the 1940 Act. ** Prior to February 7, 2005, the Old Fund, an investment vehicle established by the Fund's custodian, was used to invest cash the Fund received as collateral for securities loans.

Because all shares of the Old Fund and Quality Fund were and are held by funds in the related investment company complex, the Old Fund and Quality Fund may have been and may be considered affiliates of the Fund. *** Prime Money is also managed by Management 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. 22 <Page> FINANCIAL HIGHLIGHTS BALANCED PORTFOLIO The following table includes selected data for a share outstanding throughout each year and other performance information derived from the Financial Statements. <Table> <Caption> YEAR ENDED DECEMBER 31, -------------------------------------------------------- 2005 2004 2003 2002 2001 NET ASSET VALUE, BEGINNING OF YEAR $ 9.64 $ 8.93 $ 7.81 $ 9.66 $ 17.28 -------- -------- -------- -------- -------- INCOME FROM INVESTMENT OPERATIONS: NET INVESTMENT INCOME (LOSS)^^ .04 .05 .07 .12 .22* NET GAINS OR LOSSES ON SECURITIES (BOTH REALIZED AND UNREALIZED) .84 .77 1.20 (1.75) (2.27)* -------- -------- -------- -------- -------- TOTAL FROM INVESTMENT OPERATIONS .88 .82 1.27 (1.63) (2.05) -------- -------- -------- -------- -------- LESS DISTRIBUTIONS FROM: NET INVESTMENT INCOME (.10) (.11) (.15) (.22) (.28) NET CAPITAL GAINS -- -- -- -- (5.29) -------- -------- -------- -------- -------- TOTAL DISTRIBUTIONS (.10) (.11) (.15) (.22) (5.57) -------- -------- -------- -------- -------- NET ASSET VALUE, END OF YEAR $ 10.42 $ 9.64 $ 8.93 $ 7.81 $ 9.66 -------- -------- -------- -------- -------- TOTAL RETURN++ +9.18% +9.31% +16.28% -17.15% -13.36% RATIOS/SUPPLEMENTAL DATA NET ASSETS, END OF YEAR (IN MILLIONS) $ 73.7 $ 81.1 $ 84.9 $ 80.5 $ 112.0 RATIO OF GROSS EXPENSES TO AVERAGE NET ASSETS# 1.14% 1.10% 1.12% 1.12% 1.07% RATIO OF NET EXPENSES TO AVERAGE NET ASSETS^ 1.13% 1.09% 1.11% 1.12% 1.07% RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS .41% .56% .82% 1.37% 2.10%* PORTFOLIO TURNOVER RATE 82% 110% 121% 106% 88% </Table> See Notes to Financial Highlights 23 <Page> NOTES TO FINANCIAL HIGHLIGHTS BALANCED PORTFOLIO ++ 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.

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.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 Balanced Portfolio, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 25 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the short-, intermediate- and long-term performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered long-term performance in relation to the degree of risk undertaken by the portfolio managers. The Board discussed the Fund's performance with Management and discussed steps that Management had taken, or intended to take, to improve the Fund's performance. The Board also considered Management's resources and responsiveness with respect to the Fund. 35 <Page> With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds or separate accounts. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 36 <Page> ANNUAL REPORT DECEMBER 31, 2005 [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST FASCIANO PORTFOLIO D0081 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 FASCIANO PORTFOLIO Manager's Commentary In 2005, despite the vibrant economy and impressive corporate earnings growth, small-cap stocks made only modest progress against a headwind created by expensive energy and an extended Federal Reserve tightening cycle. For the first time in the last seven years, large-cap stocks outperformed small-caps, with the Russell 1000 returning 6.27% versus the Russell 2000's 4.55% gain. The Neuberger Berman Advisers Management Trust (AMT) Fasciano Portfolio delivered positive returns in 2005 but trailed its Russell benchmark by a small margin. This modest shortfall was due largely to the lagging performance of the Portfolio's Energy and Consumer Discretionary holdings. The Portfolio's Industrial holdings had the most positive impact on performance in 2005, with repair and maintenance equipment distributor MSC Industrial Direct and engineering and construction company Chicago Bridge and Iron appearing on our top-ten performance list. Financial sector investments, most notably property and casualty insurer HCC Insurance Holdings and municipal bond insurer Assured Guaranty LTD, also excelled. The Portfolio's Energy investments contributed substantially to absolute returns. However, because the oil services stocks we favored substantially underperformed exploration and production companies, the Portfolio's Energy sector returns lagged the benchmark's Energy component by a wide margin. The Portfolio benefited from the takeover of two holdings -- specialty pharmaceuticals distributor Priority Healthcare by Express Scripts, and water filtration equipment manufacturer CUNO by 3M. Consumer Discretionary sector investments had the most negative impact on absolute returns. The Portfolio was overweight Consumer Discretionary stocks and substantial declines in newspaper publishers Journal Register and Journal Communications, and decorative candle maker Blythe resulted in negative returns in this sector. The Portfolio also had negative returns in the Information Technology sector, with longtime holding Plantronics, the world leader in communications headsets, selling off sharply. Although the Portfolio had modest exposure to the Materials sector, the poor performance of cobalt- and nickel-based specialty chemicals producer OM Group was a significant drag on returns. We have eliminated the Portfolio's positions in Blythe and OM Group. Looking ahead, we feel positive about the economy and the stock market. Economic growth may slow a bit in 2006 as Fed rate hikes finally take hold and corporate earnings gains may not be quite as impressive. However, 3%-3.5% GDP growth and high single-digit percentage earnings gains could provide traction for stocks, especially if the Federal Reserve shifts into neutral and market interest rates remain low. Recently, we have heard considerable discussion about the relative merits of small- and large-cap stocks. The consensus seems to be that, after materially outperforming large-cap stocks for six years, small-caps may have entered what could be a prolonged period of underperformance relative to large-caps. Certainly based on price/earnings, price/book, and price/earnings over earnings-per-share-growth ratios, the valuation gap between the two groups has narrowed considerably. However, we note that small-cap companies are still less widely followed by Wall Street analysts and the investment community in general. This presents the opportunity to identify compelling investment opportunities ahead of the crowd. We look for small companies with stable earnings, strong free cash flow growth, solid financials, strong business franchises and market leading products or services, ideally in businesses that have high barriers to new competition. This translates into a Portfolio that consistently has an earnings growth rate in line with the Russell 2000, an above benchmark return on equity and a below benchmark price/earnings ratio. While we do not expect our Portfolio to outperform its benchmark every quarter or even every year, we are confident that, over the longer term, buying high quality small growth companies at below-market-average valuations will produce superior returns.

Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION As of 12/31/05 (Unaudited) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST FASCIANO PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS S $ 1,000 $ 1,061.20 $ 7.22 </Table> HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** <Table> CLASS S $ 1,000 $ 1,018.20 $ 7.07 </Table> * Expenses are equal to the expense ratio for the class, multiplied by the average account value over the period, multiplied by 184/365 (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 365. 4 <Page> SCHEDULE OF INVESTMENTS Fasciano Portfolio <Table> <Caption> NUMBER OF SHARES MARKET VALUE+ COMMON STOCKS (88.1%) BANKING & FINANCIAL (2.8%) 6,970 Boston Private Financial Holdings $ 212,027 3,500 Wilshire Bancorp 60,165 4,520 Wintrust Financial 248,148 ----------------- 520,340 BASIC MATERIALS (0.6%) 5,720 AMCOL International 117,374 BIOTECHNOLOGY (0.9%) 3,160 Techne Corp. 177,434* BUILDING, CONSTRUCTION & FURNISHING (0.4%) 3,700 Interline Brands 84,175* BUSINESS SERVICES (8.2%) 11,410 G & K Services 447,842 11,000 Korn/Ferry International 205,590* 9,300 Navigant Consulting 204,414* 4,930 Ritchie Bros.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $17,111,342. Gross unrealized appreciation of investments was $2,442,186 and gross unrealized depreciation of investments was $410,517, resulting in net unrealized appreciation of $2,031,669, 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.

The Trust is currently comprised of twelve 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 <Page> Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, 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, 2005 and December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME LONG-TERM CAPITAL GAIN TOTAL 2005 2004 2005 2004 2005 2004 $ 44,303 $ 4,205 $ 40,402 $ 31,902 $ 84,705 $ 36,107 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNDISTRIBUTED UNDISTRIBUTED UNREALIZED LOSS ORDINARY LONG-TERM APPRECIATION CARRYFORWARDS INCOME GAIN (DEPRECIATION) AND DEFERRALS TOTAL $ -- $ 598,677 $ 2,031,669 $ -- $ 2,630,346 </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales. 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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. 12 <Page> 9 SECURITY LENDING: Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund entered into a Securities Lending Agreement ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $390. Effective October 4, 2005, eSecLending acts as agent for the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income earned on the securities loaned, if any, is reflected in the Statement of Operations under the caption "Income from securities loaned-affiliated issuers." At December 31, 2005, the Fund had no securities out on loan. 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $1,331 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $48,660 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. 13 <Page> 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 aggregate, 1.40% per annum of the Fund's average daily net assets (the "Expense Limitation"). For the year ended December 31, 2005, such excess expenses amounted to $120,637. 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, 2005, there was no reimbursement to Management 14 <Page> under this agreement. At December 31, 2005, contingent liabilities to Management under this agreement were as follows: <Table> <Caption> EXPIRING IN 2006 2007 2008 TOTAL $ 92,031 $ 108,225 $ 120,637 $ 320,893 </Table> Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $1,106. The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $24. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $8,318,331 and $6,670,490, respectively. During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $19,861, of which Neuberger received $0, Lehman received $3,486, and other brokers received $16,375. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the years ended December 31, 2005 and December 31, 2004 was as follows: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, 2005 2004 SHARES SOLD 843,922 964,058 SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS 6,335 2,821 SHARES REDEEMED (665,267) (315,110) -------- -------- TOTAL 184,990 651,769 -------- -------- </Table> 15 <Page> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio manager. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered the performance in relation to the degree of risk undertaken by the portfolio manager. The Board discussed the Fund's performance with Management and discussed steps that Management had taken, or intended to take, to improve the Fund's performance. The Board also considered Management's resources and responsiveness with respect to the Fund. 29 <Page> With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board noted that Management incurred a loss on the Fund on an after-tax basis. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board compared the fees charged to a comparable sub-advised fund and a comparable separate account to the fees charged to the Fund at various asset levels. The Board considered the appropriateness and reasonableness of the differences between the fees charged between the Fund and the comparable sub-advised fund and separate account and determined that the differences in fees were consistent with the management and other services provided. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss since the Fund's inception. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 30 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST FOCUS PORTFOLIO D0080 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 FOCUS PORTFOLIO MANAGER'S COMMENTARY The uninspiring equity returns of 2005 would have been even more underwhelming were it not for the outsized contributions of Energy and Utilities stocks, by far the two best performing sectors in the S&P 500. With virtually no exposure to Energy or Utilities, the Neuberger Berman Advisers Management Trust (AMT) Focus Portfolio closed the year with a modest loss, lagging its S&P 500 and Russell 1000 Value Index benchmarks. In terms of Portfolio performance, Consumer Discretionary investments had the most positive impact on absolute and relative returns. The Portfolio was overweight in the Consumer Discretionary sector and in aggregate our holdings in the group delivered a mid-teen percentage return versus a decline for their counterparts in the benchmark. Air mattress manufacturer Select Comfort and homebuilder Centex were our two best performers in the sector and both made our top-ten contributors list. Investments in the Financial sector, which comprised the heaviest weighting in the Portfolio, were a mixed blessing, finishing the year in positive territory but lagging their respective benchmark components. Four Financial holdings--brokers Merrill Lynch and Goldman Sachs, property and casualty insurer American International Group, and financial conglomerate Citigroup--appeared on our top-ten contributors list. However, three Financial companies--credit card leader Capital One and mortgage lenders Washington Mutual and Federal National Mortgage Association (Fannie Mae)--finished near the bottom of our performance charts. Information Technology investments, the Portfolio's second largest weighting, disappointed. The Portfolio was more than double-weighted in technology and in aggregate our tech holdings declined versus a modestly positive return for the S&P 500's technology component. We had some big winners, including contract manufacturer Jabil Circuit, the Portfolio's second largest performance contributor, and Webmethods, number six on our contributors list. Unfortunately, good gains in these stocks failed to compensate for losses in International Rectifier, our largest tech holding, Flextronics, VeriSign and Computer Associates, all of which appeared on our bottom-ten list. I took over the portfolio management responsibilities of retiring Co-Manager Kent Simons on October 1, 2005 and have been gradually making some changes in the Portfolio. We are employing the same basic investment philosophy and methodology, maintaining a concentrated portfolio of high quality companies trading at deeply discounted valuations due to temporary problems either real or imagined--in Kent's words "companies under a rock or under a cloud." When we identify such companies in the future, we will continue to take substantial positions, but we are likely to limit them to 10% of Portfolio assets. We will also become more diversified by investing more of the Portfolio's assets in a broader array of industry groups. To date, we have been reducing the Portfolio's weighting in Financials and increasing its exposure in the Consumer and Health Care sectors. We are stock pickers, not economists or market timers. However, since shareholders are generally interested in our outlook for the economy and stock market, we will offer an opinion. As always, there are things to worry about, most notably the overextended consumer, expensive energy, and the potential for an economically destabilizing geopolitical event, such as military action in response to Iran's nuclear ambitions. But there are positive forces at work as well, including subdued inflation, the possibility that the Federal Reserve is close to shifting into neutral, corporate cash holdings that could finance increased capital spending, 1 <Page> synchronized global economic growth, and the fact that equity valuations appear quite reasonable. Our "best guess" is that the economy and corporate earnings will continue to grow at a decent (although slower) pace, supporting high single- to low double-digit percentage returns for equities in the year ahead. As always, our goal will be to add value through a concentrated portfolio of out-of-favor companies with above-market-average earnings growth potential. Sincerely, /s/ Robert B. Corman ROBERT B.

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(R) Index measures the performance of the 1,000 largest companies in the Russell 3000(R) 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.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION AS OF 12/31/05 (UNAUDITED) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST FOCUS PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS S $ 1,000 $ 1,004.00 $ 6.26 HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** CLASS S $ 1,000 $ 1,018.95 $ 6.31 </Table> * Expenses are equal to the expense ratio for the class, multiplied by the average account value over the period, multiplied by 184/365 (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 365. 4 <Page> SCHEDULE OF INVESTMENTS FOCUS PORTFOLIO <Table> <Caption> NUMBER OF SHARES MARKET VALUE + COMMON STOCKS (104.0%) AUTOS & HOUSING (1.7%) 1,200 Rush Enterprises Class A $ 17,856* CONSUMER GOODS & SERVICES (5.9%) 1,300 Sprint Corp. 30,368 400 Vertrue, Inc. 14,132* 800 Vodafone Group ADR 17,176 ---------------- 61,676 ENERGY (1.4%) 300 Canadian Natural Resources 14,886 FINANCIAL SERVICES (41.9%) 800 American International Group 54,584 1,732 Bank of America 79,932 1,200 Capital One Financial 103,680 1,250 Citigroup, Inc. 60,662 200 Goldman Sachs 25,542 650 J.P.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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 securities. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $836,004. Gross unrealized appreciation of investments was $261,416 and gross unrealized depreciation of investments was $12,522, resulting in net unrealized appreciation of $248,894, 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.

The Trust is currently comprised of twelve 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 <Page> Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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. The tax character of distributions paid during the years ended December 31, 2005 and December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME LONG TERM CAPITAL GAIN TOTAL 2005 2004 2005 2004 2005 2004 $ -- $ 113,929 $ 19,813 $ 6,620 $ 19,813 $ 120,549 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNREALIZED LOSS UNDISTRIBUTED UNDISTRIBUTED APPRECIATION CARRYFORWARDS ORDINARY INCOME LONG-TERM GAIN (DEPRECIATION) AND DEFERRALS TOTAL $ 18,107 $ 81,794 $ 248,894 $ -- $ 348,795 </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales. 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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 SECURITY LENDING: Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund entered into a Securities Lending Agreement ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the 11 <Page> Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger did not receive any revenue under the Neuberger Agreement. Effective October 4, 2005, eSecLending acts as agent for the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income earned on the securities loaned, if any, is reflected in the Statement of Operations under the caption "Income from securities loaned-affiliated issuers." At December 31, 2005, the Fund had no securities out on loan. 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $18 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $716, 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. 12 <Page> 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, 2005, such excess expenses amounted to $89,000. 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, 2005, there was no reimbursement to Management 13 <Page> under this agreement. At December 31, 2005, contingent liabilities to Management under this agreement were as follows: <Table> <Caption> EXPIRING IN: 2006 2007 2008 TOTAL $ 77,957 $ 80,604 $ 89,000 $ 247,561 </Table> Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $103. The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $0. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $494,373 and $620,597, respectively. During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $1,996, of which Neuberger received $205, Lehman received $95, and other brokers received $1,696. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the years ended December 31, 2005 and December 31, 2004 was as follows: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, 2005 2004 SHARES SOLD 2,441 5,164 SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS 1,131 7,275 SHARES REDEEMED (9,959) (8,787) ------- ------- TOTAL (6,387) 3,652 ------- ------- </Table> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on 14 <Page> the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 18 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered the performance in relation to the degree of risk undertaken by the portfolio managers. With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. 28 <Page> The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board noted that Management incurred a loss on the Fund on an after-tax basis. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds or separate accounts. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss since the Fund's inception. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; the performance of the Fund was satisfactory; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 29 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST GROWTH PORTFOLIO(R) B1015 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 GROWTH PORTFOLIO MANAGERS' COMMENTARY The Neuberger Berman Advisers Management Trust (AMT) Growth Portfolio generated a positive return in 2005, outperforming its benchmark, the Russell Midcap Growth Index. The Portfolio ranked in the top 25% of its Lipper peer group, as strong stock selection and sector allocations enhanced performance relative to the benchmark. Over the course of the year, impressive corporate earnings gains, a strong economy and healthy profit margins supported equity performance but were offset by the Federal Reserve's relentless increases in short-term interest rates. Energy was the best performing sector, reflecting record highs in crude oil prices due to increased Asian demand and a strong U.S. economy. Sectors tied to the consumer were generally the weakest of the year as personal income was squeezed by higher energy costs and interest rates. For the Portfolio, the most significant contributors to performance were securities in the Financials, Energy and Health Care sectors. Within Financials, stocks that did well included business services companies such as the Chicago Mercantile Exchange and brokerage firms such as Legg Mason. Within Energy, names that did well included Peabody Energy and Canadian Natural Resources. Stock selection within Health Care benefited Portfolio results with Celgene, a particularly strong performer in 2005. Also additive to relative return were holdings in the Consumer Staples sector, including Whole Foods Market and Constellation Brands. In aggregate, our sector allocation also contributed to performance, with Portfolio overweights in Telecom and Energy--two of 2005's best performing sectors--providing much of the value added. Stock selection within Information Technology had the most negative impact on relative performance. Within this sector, various software companies showed weakness, while some business services companies also underperformed. Moving forward, we believe that domestic consumers remain financially stretched. Real wage growth has been non-existent this economic cycle. Instead, consumer spending has been driven by strong housing gains and additional debt. Housing now contributes over 6% of GDP and is showing signs of slowing. Housing inventories are at a nine-year high and affordability has hit a new low. We do not expect a housing price collapse, but this major support for consumer spending is weakening, which could slow economic activity. Although data are somewhat ambiguous, there is evidence that U.S. economic growth is slowing. In contrast, foreign economies in Asia, Japan and even Europe are exhibiting increased economic activity. As such, we want the Portfolio to be tilted toward beneficiaries of global economic expansion and corporate spending and away from exposure to the beleaguered American consumer. Throughout 2005, there was little change in our strategic position. However, at some point in the months ahead we expect to become more defensive and move up the market capitalization spectrum. For now, we want to let the past market leadership play out before making a change. If, as we expect, the market progresses higher in the first part of the year, we currently anticipate making rotational changes into more traditional growth areas. Currently, Energy, Information Technology, Industrials and Health Care are all overweighted in the Portfolio while Consumer Staples and Discretionary, Utilities and Financials remain underweighted.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $145,514,474. Gross unrealized appreciation of investments was $66,087,147 and gross unrealized depreciation of investments was $974,702, resulting in net unrealized appreciation of $65,112,445, based on cost for U.S. Federal income tax purposes. * Non-income producing security. ^ All or a portion of this security is on loan (see Note A of Notes to Financial Statements). ++ Managed by an affiliate of Neuberger Berman Management Inc. and could be deemed an affiliate of the Fund (see Notes A & F of Notes to Financial Statements).

--------------------------------------------------------------------------------------------------- </Table> See Notes to Financial Statements 10 <Page> 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 twelve 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, 2005 was $925. 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 <Page> investment companies and to distribute substantially all of its earnings to its shareholders. Therefore, no Federal income or excise tax provision is required. Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, 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, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis was as follows: <Table> <Caption> UNDISTRIBUTED UNREALIZED LOSS ORDINARY APPRECIATION CARRYFORWARDS INCOME (LOSS) (DEPRECIATION) AND DEFERRALS TOTAL $ -- $ 65,112,422 $ (262,319,110) $ (197,206,688) </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales and capital loss carryforwards. 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, 2005, the Fund had unused capital loss carryforwards available for Federal income tax purposes to offset net realized capital gains, if any, as follows: <Table> <Caption> EXPIRING IN: 2009 2010 $ 192,199,313 $ 70,119,797 </Table> 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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 12 <Page> 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 ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $14,794. Effective September 13, 2005, the Fund entered into new securities lending arrangements using a third party, eSecLending, to secure bids. Pursuant to such arrangements, eSecLending currently acts as agent for the Fund arranging principals to guarantee a certain amount of revenue to the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income from the lending program represents income earned on the cash collateral and the guaranteed amount, less fees and expenses associated with the loans. These amounts are reflected in the Statement of Operations under the caption "Income from securities loaned (affiliated issuers)." 10 REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements with institutions that Management 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime 13 <Page> Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $292 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $10,867 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, 2005, 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, 2005, there was no reimbursement to Management 14 <Page> under this agreement. At December 31, 2005, the Fund has no contingent liability to Management under this agreement. Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $23,973. The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $664. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $103,222,697 and $143,186,452, respectively. During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $322,238, of which Neuberger received $200, Lehman received $51,477, and other brokers received $270,561. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the years ended December 31, 2005 and December 31, 2004 was as follows: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, 2005 2004 SHARES SOLD 586,157 794,788 SHARES REDEEMED (3,464,321) (4,284,573) ---------- ---------- TOTAL (2,878,164) (3,489,785) ---------- ---------- </Table> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. 15 <Page> No compensating balance is required. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit.

Because all shares of the Old Fund and Quality Fund were and are held by funds in the related investment company complex, the Old Fund and Quality Fund may have been and may be considered affiliates of the Fund. *** Prime Money is also managed by Management 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. 16 <Page> FINANCIAL HIGHLIGHTS GROWTH PORTFOLIO The following table includes selected data for a share outstanding throughout each year and other performance information derived from the Financial Statements. <Table> <Caption> YEAR ENDED DECEMBER 31, ----------------------------------------------------------------- 2005 2004 2003 2002 2001 NET ASSET VALUE, BEGINNING OF YEAR $ 12.15 $ 10.42 $ 7.93 $ 11.52 $ 30.65 --------- --------- --------- --------- --------- INCOME FROM INVESTMENT OPERATIONS: NET INVESTMENT INCOME (LOSS)** (.07) (.06) (.05) (.06) (.07) NET GAINS OR LOSSES ON SECURITIES (BOTH REALIZED AND UNREALIZED) 1.71 1.79 2.54 (3.53) (7.41) --------- --------- --------- --------- --------- TOTAL FROM INVESTMENT OPERATIONS 1.64 1.73 2.49 (3.59) (7.48) --------- --------- --------- --------- --------- LESS DISTRIBUTIONS FROM: NET CAPITAL GAINS -- -- -- -- (11.65) --------- --------- --------- --------- --------- NET ASSET VALUE, END OF YEAR $ 13.79 $ 12.15 $ 10.42 $ 7.93 $ 11.52 --------- --------- --------- --------- --------- TOTAL RETURN++ +13.50% +16.60% +31.40% -31.16% -30.36% RATIOS/SUPPLEMENTAL DATA NET ASSETS, END OF YEAR (IN MILLIONS) $ 196.5 $ 208.1 $ 214.9 $ 185.8 $ 356.2 RATIO OF GROSS EXPENSES TO AVERAGE NET ASSETS# 1.00% .96% .94% .96% .89% RATIO OF NET EXPENSES TO AVERAGE NET ASSETS .99%^ .94%^ .93%^ .96% .89% RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS (.55%) (.51%) (.58%) (.65%) (.50%) PORTFOLIO TURNOVER RATE 53% 83% 149% 97% 91% </Table> See Notes to Financial Highlights 17 <Page> NOTES TO FINANCIAL HIGHLIGHTS GROWTH PORTFOLIO ++ 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.

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.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 19 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the short-, intermediate- and long-term performance of the Fund, relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered long-term performance in relation to the degree of risk undertaken by the portfolio managers. The Board discussed the Fund's performance with Management and discussed steps that Management had taken, or intended to take, to improve the Fund's performance. The Board also considered Management's resources and responsiveness with respect to the Fund. The Board noted that the Fund's performance has improved over the past year. 29 <Page> With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board compared the fees charged to a comparable sub-advised fund and a comparable separate account to the fees charged to the Fund at various asset levels. The Board considered the appropriateness and reasonableness of the differences between the fees charged between the Fund and the comparable sub-advised fund and separate account and determined that the differences in fees were consistent with the management and other services provided. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 30 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST GUARDIAN PORTFOLIO B1016 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 GUARDIAN PORTFOLIO MANAGER'S COMMENTARY In 2005, a vibrant economy and strong corporate earnings growth failed to impress investors preoccupied by increasingly high energy costs and a seemingly never-ending series of Federal Reserve rate hikes. Although most stock market indices finished the year in positive territory, this was largely the result of the exceptional performance of Energy stocks and a few interest rate sensitive groups such as Homebuilders and Utilities. We are pleased to report that the Neuberger Berman Advisers Management Trust (AMT) Guardian Portfolio outperformed its S&P 500 and Russell 1000 Value benchmarks despite being underweighted in the stock market's top performing industry groups and sectors. With our holdings outperforming benchmark components in seven of ten economic sectors, stock selection deserves all the credit for the Portfolio's superior relative performance. The Portfolio's Energy investments had the most positive impact on absolute and relative returns. The Portfolio was modestly underweighted in Energy versus the S&P 500, but our holdings outperformed by a substantial margin, with Newfield Exploration finishing number one on our top-ten contributors list. Led by longtime holding UnitedHealth Group, our third largest performance contributor, and Millipore, number six on our performance charts, the return of our Health Care sector investments more than tripled the S&P 500's sector components. Financial sector holdings such as Goldman Sachs, State Street and AMB Property, all of which made our top-ten list, enhanced performance. Led by Canadian National Railway, Industrial sector investments also delivered superior relative returns. Although materially outperforming S&P 500 sector components, our Consumer Discretionary investments declined modestly. Gains in Toyota Motor Corp. and BorgWarner, Inc. among the stronger stocks in the troubled auto industry, helped offset declines in media holdings such as Liberty Media and Comcast Corp. The Portfolio's substantial underweighting in Utilities, the stock market's second best performing sector, penalized relative returns. Technology was a mixed bag, with Texas Instruments and National Instruments near the top of our performance list and Dell, Teradyne and Altera near the bottom. Ever since the tech bubble burst in second quarter 2000, investors have been skittish about technology stocks, adequately rewarding good news but punishing companies that fall just short of consensus expectations. That's why, over the short term, equally high quality companies in the same industry sector such as semiconductor manufacturers Texas Instruments and Altera can be on opposite ends of the performance spectrum. The good thing that has come from investors' paranoia about tech stocks is that we have been able to find more great companies selling at attractive valuations. It is no accident that the AMT Guardian Portfolio tends to be underweighted in the stock market's hottest sectors and overweighted in out-of-favor groups. We are in the business of buying high quality companies at discounted valuations and, consequently, are often leaning into the prevailing market winds. As long-term investors, we run the risk of being early in our stock calls, but are quite comfortable with this posture because we believe that our research-driven and valuation-sensitive investment process will translate into superior long-term results. Looking ahead, while we have our worries, most notably the potential for wage/energy driven inflation and/or some destabilizing geopolitical event, we are cautiously optimistic about the prospects for stocks. Barring the unforeseeable, we believe that the economy will continue to expand and that corporate earnings will grow at a decent rate. With earnings growth outpacing stock price appreciation over the last two years, equity valuations have become more compelling. Also, the narrow performance of the 2005 market has resulted in a greater number of legitimate fundamental bargains in a broader range of industry groups. Finally, we believe that the type of high quality stable earners we favor will attract investor attention in what may be a slower growth economy in the year ahead.

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(R) Index measures the performance of the 1,000 largest companies in the Russell 3000(R) 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 fund 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.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION AS OF 12/31/05 (UNAUDITED) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST GUARDIAN PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS I $ 1,000 $ 1,093.40 $ 5.33 CLASS S $ 1,000 $ 1,093.00 $ 6.59 HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** CLASS I $ 1,000 $ 1,020.11 $ 5.14 CLASS S $ 1,000 $ 1,018.90 $ 6.36 </Table> * 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 184/365 (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 365. 4 <Page> SCHEDULE OF INVESTMENTS GUARDIAN PORTFOLIO <Table> <Caption> NUMBER OF SHARES MARKET VALUE+ COMMON STOCKS (96.7%) AUTOMOTIVE (4.4%) 43,800 BorgWarner, Inc. $ 2,655,594 48,850 Toyota Motor Corp.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $135,618,882. Gross unrealized appreciation of investments was $42,343,750 and gross unrealized depreciation of investments was $789,221, resulting in net unrealized appreciation of $41,554,529, based on cost for U.S. Federal income tax purposes. * Non-income producing security. ^ All or a portion of this security is on loan (see Note A of Notes to Financial Statements). ++ Managed by an affiliate of Neuberger Berman Management Inc. and could be deemed an affiliate of the Fund (see Notes A & F 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 Trust is currently comprised of twelve 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 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, 2005 was $4,737. 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 <Page> investment companies and to distribute substantially all of its earnings to its shareholders. Therefore, no Federal income or excise tax provision is required. Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, 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, 2005 and December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME TOTAL 2005 2004 2005 2004 $ 254,084 $ 201,368 $ 254,084 $ 201,368 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNREALIZED LOSS UNDISTRIBUTED APPRECIATION CARRYFORWARDS ORDINARY INCOME (DEPRECIATION) AND DEFERRALS TOTAL $ 1,039,483 $ 41,553,609 $ (25,850,361) $ 16,742,731 </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales, return of capital distributions from real estate investment trusts, and capital loss carry forwards. 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, 2005, the Fund had unused capital loss carryforwards available for Federal income tax purposes to offset net realized capital gains, if any, as follows: <Table> <Caption> EXPIRING IN: 2010 2011 $ 20,299,228 $ 5,551,133 </Table> 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-date. 11 <Page> 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 ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guarantees a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $18,780. Under the Neuberger Agreement, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income from the lending program represents income earned on the cash collateral and the guaranteed amount, less fees and expenses associated with the loans. These amounts are reflected in the Statement of Operations under the caption "Income from securities loaned-affiliated issuers." 10 REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements with institutions that Management 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 <Page> 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $2,888 and is reflected in the Statement of Operation under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $111,138 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. 13 <Page> 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 to reimburse the Fund's Class I and Class S shares for their operating expenses (including the fees payable to Management but excluding interest, taxes, brokerage commissions, extraordinary expenses, and transaction costs) ("Operating Expenses") which exceed the expense limitation as detailed in the following table: <Table> <Caption> REIMBURSEMENT FROM MANAGEMENT FOR THE EXPENSE YEAR ENDED LIMITATION(1) EXPIRATION DECEMBER 31, 2005 Class I 1.00% 12/31/08 - Class S 1.25% 12/31/08 $ 61 </Table> (1) Expense limitation per annum of the respective class' average daily net assets. Each Respective class has agreed to repay Management through December 31, 2011 for its excess Operating Expenses previously reimbursed by Management, so long as their annual Operating Expenses during that period do not exceed their 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, 2005, there was no reimbursement to Management under these agreements. At December 31, 2005, Class S had a contingent liability of $61 to Management under these agreements which expires in 2008. Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $9,771. 14 <Page> The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $528. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $52,450,514 and $66,288,295, respectively. During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $124,057, of which Neuberger received $0, Lehman received $22,653 and other brokers received $101,404. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the years ended December 31, 2005 and December 31, 2004 was as follows: FOR THE YEAR ENDED DECEMBER 31, 2005 <Table> <Caption> SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND SHARES SHARES SOLD DISTRIBUTIONS REDEEMED TOTAL CLASS I 1,602,969 15,325 (2,569,093) (950,799) CLASS S 8,512 - (786) 7,726 </Table> FOR THE YEAR ENDED DECEMBER 31, 2004 <Table> <Caption> SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND SHARES SHARES SOLD DISTRIBUTIONS REDEEMED TOTAL CLASS I 1,465,738 13,945 (2,616,915) (1,137,232) CLASS S 8,295 - (973) 7,322 </Table> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to the line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit. 15 <Page> NOTE F--INVESTMENTS IN AFFILIATES*: <Table> <Caption> INCOME FROM INVESTMENTS BALANCE OF BALANCE OF IN SHARES GROSS SHARES AFFILIATED HELD GROSS SALES HELD VALUE ISSUERS DECEMBER 31, PURCHASES AND DECEMBER 31, DECEMBER 31, INCLUDED IN NAME OF ISSUER 2004 AND ADDITIONS REDUCTIONS 2005 2005 TOTAL INCOME Neuberger Berman Securities Lending Quality Fund, LLC ** 12,113,700 370,399,176 381,505,276 1,007,600 $ 1,007,600 $ 17,601 Neuberger Berman Prime Money Fund Trust Class*** 5,483,289 52,532,711 51,758,869 6,257,131 6,257,131 111,138 ------------ ------------ TOTAL $ 7,264,731 $ 128,739 ============ ============ </Table> * Affiliated issuers, as defined in the 1940 Act. ** Prior to February 7, 2005, the Old Fund, an investment vehicle established by the Fund's custodian, was used to invest cash the Fund received as collateral for securities loans.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 19 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the short-, intermediate- and long-term performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered long-term performance in relation to the degree of risk undertaken by the portfolio managers. The Board discussed the Fund's performance with Management and discussed steps that Management had taken, or intended to take, to improve the Fund's performance. The Board also considered Management's resources and responsiveness with respect to the Fund. The Board noted that the Fund's performance has improved over the past year. 29 <Page> With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds or separate accounts. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 30 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST HIGH INCOME BOND PORTFOLIO E0633 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 HIGH INCOME BOND PORTFOLIO Managers' Commentary The Neuberger Berman Advisers Management Trust (AMT) High Income Bond Portfolio earned a 1.20% return in 2005, compared to a 2.81% return for the Lehman Brothers Intermediate Ba U.S. High Yield Index. The primary reason for this return shortfall was an overweight position in cyclical sectors at a time when these positions underperformed the overall market. This occurred primarily in the first half of the year. In the second half, the Portfolio performed essentially in line with the market index. 2005 IN REVIEW The high yield market was volatile in 2005 largely due to changes in interest rates. With fears of higher inflation, a spike in Treasury rates, and Federal Reserve Chairman Greenspan's comments about a bond market "conundrum," high yield bonds declined in value. While interest rates were the main culprit, a modest increase in spreads over the course of the year also contributed to price declines. However, the attractive coupons associated with high yield securities more than offset any price declines and resulted in a positive overall return for the market. A notable development in 2005 was the declining credit standing of companies in auto and auto-related sectors. In March 2005, General Motors revised its expectations for cash flow from positive $2 billion to negative $2 billion. This announcement focused investors' attention on credit risk, heightened expectations for a ratings downgrade of GM, and increased spread volatility across the credit markets. Ultimately, GM was downgraded to below-investment-grade in May 2005, followed by Ford's downgrade in the fourth quarter of the year. 2006 OUTLOOK Looking ahead, we believe there are four factors that bode well for the high yield market. First, we anticipate that the Federal Reserve Board's tightening cycle will end in the first part of the year. Second, although default rates among lower quality issuers may experience a slight uptick, we believe that defaults will remain below historical norms. Third, credit fundamentals are appealing as corporations have strengthened their balance sheets. Finally, high yield issues continue to offer an attractive yield opportunity, which will help cushion any increase in spread levels. STRATEGY The Portfolio's strategy is three-pronged. First, it is weighted toward intermediate-duration bonds. The potential for increasing interest rates, coupled with a flat credit curve, suggest that a shorter duration with respect to interest rates and spreads may be appropriate. Second, the Portfolio's emphasis is on BB-rated issues due to the historically narrow spread differential between BB- and B-rated issues. Third, across sectors and issuers, the Portfolio is overweight industries with stable cash flows such as cable, media, health care and gaming. We currently intend for the Portfolio to continue the process started in 2005 of moving toward a more defensive posture with underweight positions in cyclical sectors including paper, metals and chemicals. With regard to individual issue selection, we intend for the Portfolio to seek to avoid bond deals that focus on shareholder friendly transactions, such as leveraged buyouts, that are not typically advantageous for debt holders.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" to estimate the expenses you paid over the period. HYPOTHETICAL EXAMPLE FOR COMPARISON The second section of the table PURPOSES: 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION As of 12/31/05 (Unaudited) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST HIGH INCOME BOND PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS S $ 1,000 $ 1,010.00 $ 5.57 </Table> HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** <Table> CLASS S $ 1,000 $ 1,019.66 $ 5.60 </Table> * Expenses are equal to the expense ratio for the class, multiplied by the average account value over the period, multiplied by 184/365 (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 365. 4 <Page> SCHEDULE OF INVESTMENTS High Income Bond Portfolio <Table> <Caption> PRINCIPAL AMOUNT RATING ~ MARKET VALUE + Moody's S&P CORPORATE DEBT SECURITIES (96.7%) $ 50,000 AES Corp., Senior Secured Notes, 8.75%, due 5/15/13 Ba3 B+ $ 54,437** 100,000 Allied Waste North America, Inc., Guaranteed Senior Secured Notes, Ser.

For all other securities, bid prices are obtained from principal market makers in those securities or, if quotations are not available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust has approved on the belief that they reflect 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 Trust is currently comprised of twelve 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 had 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 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 <Page> Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, permanent differences resulting primarily from different book and tax accounting for characterization of distributions made by the Fund 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 year ended December 31, 2005 and the period ended December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME 2005 2004 $ 202,437 $ 45,990 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNREALIZED LOSS UNDISTRIBUTED APPRECIATION CARRYFORWARDS ORDINARY INCOME (DEPRECIATION) AND DEFERRALS TOTAL $ 2,576 $ (61,451) $ (67,188) $ (126,063) </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to post October losses and capital loss carryforwards. 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, 2005, the Fund elected to defer $42,817 of net capital losses arising between November 1, 2005 and December 31, 2005. 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 on December 31, 2005, the Fund had unused capital loss carryforwards available for Federal income tax purposes to offset net realized capital gains, if any, as follows: <Table> <Caption> EXPIRING IN: 2013 $ 24,371 </Table> 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund earns income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-date. 12 <Page> 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 Management 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 13 <Page> 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 year ended December 31, 2005, such excess expenses amounted to $90,516. 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, 2005, there was no reimbursement to Management under this agreement. At December 31, 2005, contingent liabilities to Management under this agreement were as follows: <Table> <Caption> EXPIRING IN: 2007 2008 TOTAL $ 31,571 $ 90,516 $ 122,087 </Table> Management and Neuberger Berman, LLC ("Neuberger"), a member firm of the New York Stock Exchange and sub-adviser to the Fund, are 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, 2005, the impact of this arrangement was a reduction of expenses of $1,002. 14 <Page> NOTE C--SECURITIES TRANSACTIONS: Cost of purchases and proceeds of sales and maturities of long-term securities for the year ended December 31, 2005 were as follows: <Table> <Caption> SALES AND MATURITIES PURCHASES OF PURCHASES EXCLUDING SALES AND MATURITIES EXCLUDING U.S. GOVERNMENT U.S. GOVERNMENT OF U.S. GOVERNMENT U.S. GOVERNMENT AND AND AGENCY AND AGENCY AND AGENCY AGENCY OBLIGATIONS OBLIGATIONS OBLIGATIONS OBLIGATIONS $ -- $ 5,705,078 $ -- $ 4,654,094 </Table> NOTE D--FUND SHARE TRANSACTIONS: Share activity for the year ended December 31, 2005 and for the period ended December 31, 2004 was as follows: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, FOR THE PERIOD ENDED DECEMBER 31, 2005 2004 SHARES SOLD 93,679 300,000 SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS 20,850 4,558 SHARES REDEEMED (4,502) -- ------- ------- TOTAL 110,027 304,558 ------- ------- </Table> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit. 15 <Page> FINANCIAL HIGHLIGHTS High Income Bond Portfolio The following table includes selected data for a share outstanding throughout each period and other performance information derived from the Financial Statements. <Table> <Caption> YEAR PERIOD FROM ENDED SEPTEMBER 15, 2004^ DECEMBER 31, TO DECEMBER 31, 2005 2004 ------------ -------------------- NET ASSET VALUE, BEGINNING OF PERIOD $ 10.09 $ 10.00 ------------ -------------------- INCOME FROM INVESTMENT OPERATIONS: NET INVESTMENT INCOME (LOSS)++ .54 .13 NET GAINS OR LOSSES ON SECURITIES (BOTH REALIZED AND UNREALIZED) (.42) .11 ------------ -------------------- TOTAL FROM INVESTMENT OPERATIONS .12 .24 ------------ -------------------- LESS DISTRIBUTIONS FROM: NET INVESTMENT INCOME (.46) (.14) NET CAPITAL GAINS (.06) (.01) ------------ -------------------- TOTAL DISTRIBUTIONS (.52) (.15) ------------ -------------------- NET ASSET VALUE, END OF PERIOD $ 9.69 $ 10.09 ------------ -------------------- TOTAL RETURN++ +1.20% +2.43%** RATIOS/SUPPLEMENTAL DATA NET ASSETS, END OF PERIOD (IN MILLIONS) $ 4.0 $ 3.1 RATIO OF GROSS EXPENSES TO AVERAGE NET ASSETS# 1.14% 1.13%* RATIO OF NET EXPENSES TO AVERAGE NET ASSETS@ 1.11% 1.10%* RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS 5.33% 4.39%* PORTFOLIO TURNOVER RATE 143% 104%** </Table> See Notes to Financial Highlights 16 <Page> NOTES TO FINANCIAL HIGHLIGHTS High Income Bond Portfolio ++ 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.

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 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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2005 by correspondence with the custodian and brokers. 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 High Income Bond Portfolio as of December 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for the year then ended and for the period from September 15, 2004 to December 31, 2004, in conformity with accounting principles generally accepted in the United States of America.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered the performance in relation to the degree of risk undertaken by the portfolio managers. The Board discussed the Fund's performance with Management and discussed steps that Management had taken, or intended to take, to improve the Fund's performance. The Board also considered Management's resources and responsiveness with respect to the Fund. With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. 28 <Page> The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limits on Fund expenses undertaken by Management for the Fund. The Board noted that Management incurred a loss on the Fund on an after-tax basis. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds. The Board compared the fees charged to a comparable separate account to the fees charged to the Fund at various asset levels. The Board considered the appropriateness and reasonableness of the differences between the fees charged between the Fund and the comparable separate account and determined that the differences in fees were consistent with the management and other services provided. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered whether the Fund's fee structure should provide for a reduction of payments resulting from the use of breakpoints. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund since the Fund's inception. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 29 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST INTERNATIONAL PORTFOLIO(R) F0509 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 INTERNATIONAL PORTFOLIO MANAGER'S COMMENTARY The Neuberger Berman Advisers Management Trust (AMT) International Portfolio was introduced on April 29, 2005. From inception through year-end 2005, the Portfolio provided a 17.50% return, slightly underperforming its MSCI EAFE benchmark. Energy holdings made the largest contribution to performance. The Portfolio was more than double-weighted in Energy versus the EAFE benchmark and its Energy stocks more than quintupled the return from EAFE Energy components. Our success in this sector was largely due to our focus on stocks outside of EAFE's boundaries (three Canadian, one Brazilian and one Argentine company made our top-ten contributors list) and the fact that we favored "upstream" exploration, production and energy services companies, which significantly outperformed "downstream" refiners and marketers. Information Technology, Consumer Staples and Financial investments also made significant contributions to returns. Their performance was driven by holdings including TPV Technology (an IT company in Hong Kong), C&C Group (Staples, Ireland), Kensington Group (Financials, U.K.), Anglo Irish Bank (Financials, Ireland), and Option NV (IT, Belgium). On a geographic basis, we were generously rewarded for investing in non-EAFE nations, especially Argentina, Brazil and Canada, where domestically-oriented firms as well as Energy names were strong performers. Our ongoing commitment to smaller European markets such as Ireland, Belgium, and Norway also enhanced relative returns. We continue to see compelling opportunities in Europe's smaller, often more dynamic, economies. Of course, not everything worked as well as we would have liked. The Portfolio's shares in U.K. telecom giant Vodafone and Greece's Public Power Corp. declined sharply. Although the Portfolio enjoyed gains in the Consumer Discretionary, Industrial and Utility sectors, it materially underperformed the pertinent EAFE sector components. Great Canadian Gaming, the U.K.'s MFI Furniture Group and Trinity Mirror penalized relative returns in the Consumer Discretionary sector. Japanese arcade equipment manufacturer Mars Engineering was the biggest loser in the Industrial sector and Japanese Materials company Tamron also held back returns. On a country basis, the Portfolio's underweighting and weak relative performance in Japan restrained returns. We maintained a cautious view on the economic recovery in Japan and, as a result, the Portfolio was positioned rather defensively, in less economically sensitive companies. These "low beta" stocks lagged cyclical companies by a wide margin as investors gained confidence that the Japanese economy was finally gaining some traction. Looking ahead, international equity valuations appear less compelling after the excellent performance of recent years. With GDP growth unlikely to accelerate and central banks from Europe to Japan likely to raise short-term interest rates, stocks face some headwinds. Consequently, we doubt that international equity returns will be quite as generous in 2006 as they have been over the past three years. We expect to see total percentage returns in the very low double-digits, with perhaps 5% coming from stock price appreciation and dividends and the balance from favorable currency translation--if, as we anticipate, the dollar once again weakens against the euro and yen. Of course, we will be striving to outperform market returns through our research-driven stock selection methodology.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION AS OF 12/31/05 (UNAUDITED) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST INTERNATIONAL PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS S $ 1,000 $ 1,128.70 $ 8.05 HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** CLASS S $ 1,000 $ 1,017.64 $ 7.63 </Table> * Expenses are equal to the expense ratio for the class, multiplied by the average account value over the period, multiplied by 184/365 (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 365. 4 <Page> SCHEDULE OF INVESTMENTS INTERNATIONAL PORTFOLIO <Table> <Caption> NUMBER OF SHARES MARKET VALUE + COMMON STOCKS (79.3%) ARGENTINA (0.9%) 1,025 Tenaris SA ADR $ 117,362 AUSTRALIA (3.3%) 122,230 Hardman Resources 156,139* 15,590 Timbercorp Ltd. 34,336 7,720 Woodside Petroleum 222,115 --------------- 412,590 BELGIUM (3.6%) 4,720 Euronav SA 136,997 1,890 Fortis 60,318 5,220 InBev NV 227,294 520 Omega Pharma SA 27,101 --------------- 451,710 BRAZIL (1.8%) 3,285 Petroleo Brasileiro ADR 234,122* CANADA (9.1%) 4,380 Canadian Natural Resources 216,492 960 Canadian Western Bank 29,485 4,500 Corus Entertainment Inc., B Shares 120,417 12,040 Great Canadian Gaming 169,146* 6,100 MacDonald Dettwiler 196,192* 2,100 Suncor Energy 132,057 5,520 Talisman Energy 291,635 --------------- 1,155,424 FINLAND (0.0%) 300 Orion Oyj, B Shares 5,556 FRANCE (4.6%) 2,260 BNP Paribas 182,924 790 Ipsos 104,778 1,540 Publicis Groupe 53,616 820 Saft Groupe SA 18,440* 640 Societe Generale 78,745 1,095 Total SA ADR 138,408 --------------- 576,911 GERMANY (2.0%) 910 Continental AG 80,800 1,910 Rhoen-Klinikum AG 72,718 890 Wincor Nixdorf AG 94,190 --------------- 247,708 GREECE (0.8%) 2,450 Titan Cement 100,094 HONG KONG (1.2%) 160,000 TPV Technology 155,800 IRELAND (8.6%) 4,110 Allied Irish Banks 88,386 22,909 Anglo Irish Bank 347,792 37,794 C&C Group 239,890 7,177 CRH PLC 211,115 170 DCC PLC 3,644 42,290 Dragon Oil PLC 144,273* 4,800 Grafton Group PLC $ 51,498* --------------- 1,086,598 ITALY (1.3%) 6,810 Indesit Co. 70,483 14,520 Milano Assicurazioni 99,299 --------------- 169,782 JAPAN (12.9%) 1,000 Acom Co. 64,303 3,000 Aica Kogyo 41,177 31,000 Brother Industries 325,831 1,000 CHIYODA Corp. 22,990 3,500 F.C.C.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $11,628,795. Gross unrealized appreciation of investments was $660,693 and gross unrealized depreciation of investments was $142,362, resulting in net unrealized appreciation of $518,331, 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.

The Trust is currently comprised of twelve 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 commenced operations on April 29, 2005 and 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-date or, for certain foreign dividends, as soon as the Fund becomes aware of the dividends. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income, including accretion of original issue discount, where applicable, and accretion of discount on short-term investments, is recorded on the accrual basis. Realized gains and losses from securities transactions and foreign currency transactions are recorded on the basis of identified cost and stated separately in the Statement of Operations. 5 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. 11 <Page> Income distributions and capital gain distributions are determined in accordance with U.S. income tax regulations, which may differ from U.S. 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, 2005, permanent differences resulting primarily from different book and tax accounting for foreign currency gain and losses and non-deductible start-up costs were reclassified at year end. These reclassifications had no effect on the net income, net assets or net assets per share of the fund. The tax character of distributions paid during the period ended December 31, 2005 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME TOTAL 2005 2005 $ 67,162 $ 67,162 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNDISTRIBUTED UNREALIZED ORDINARY APPRECIATION INCOME (DEPRECIATION) TOTAL $ 60,517 $ 518,114 $ 578,631 </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales and passive foreign investment companies. 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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. 12 <Page> 9 REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements with institutions that Management 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 REDEMPTION OF FUND SHARES: The Fund charges a redemption fee of 1% on shares redeemed or exchanged for shares of another fund within 60 days or less of the purchase date. All redemption fees are paid to and recorded by the Fund as Paid-in capital. For the period ended December 31, 2005, the Fund received $2,126 in redemption fees. 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the period ended December 31, 2005, management fees waived under this Arrangement amounted to $286 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the period ended December 31, 2005, income earned under this Arrangement amounted to $13,171 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 0.85% of the first $250 million of the Fund's average daily net assets, 0.825% of the next $250 million, 0.80% of the 13 <Page> next $250 million, 0.775% of the next $250 million, 0.75% of the next $500 million, 0.725% of the next $1 billion, and 0.70% 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 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, 2.00% 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 0.50% per annum of the Fund's average daily net assets to maintain the Fund's Operating Expense at 1.50%. Management may, at its sole discretion, terminate this voluntary reimbursement commitment without notice. For the period ended December 31, 2005, such excess expenses amounted to $103,834. The Fund has agreed to repay Management through December 31, 2011 for its excess Operating Expenses previously reimbursed by Management under the contractual Expense Limitation, 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, 2005, there was no reimbursement to Management under this agreement. At December 31, 2005, contingent liabilities to Management under this agreement were as follows: <Table> <Caption> EXPIRING IN 2008 $ 91,847 </Table> 14 <Page> Management and Neuberger Berman, LLC ("Neuberger"), a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has an expense offset arrangement in connection with its custodian contract. For the period ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $184. NOTE C--SECURITIES TRANSACTIONS: During the period ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $10,748,514 and $915,201, respectively. During the period ended December 31, 2005, brokerage commissions on securities transactions amounted to $9,783, of which Neuberger received $0, Lehman received $3,087, and other brokers received $6,696. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the period ended December 31, 2005 was as follows: <Table> <Caption> FOR THE PERIOD ENDED DECEMBER 31, 2005 SHARES SOLD 1,105,462 SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS 5,780 SHARES REDEEMED (28,174) --------- TOTAL 1,083,068 --------- </Table> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was one of three holders of a single $20,000,000 uncommitted, secured line of credit with a consortium of banks organized by State Street to be used only for temporary or emergency purposes or for leverage. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged at LIBOR, or the overnight Federal Funds Rate, plus a spread to be determined at the time of borrowing. Because several investment companies participate, there is no assurance that the Fund will have access to the entire $20,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the period ended December 31, 2005, the Fund did not utilize this line of credit. 15 <Page> NOTE F--INVESTMENTS IN AFFILIATES*: <Table> <Caption> INCOME FROM INVESTMENTS BALANCE OF BALANCE OF IN SHARES GROSS SHARES AFFILIATED HELD GROSS SALES HELD VALUE ISSUERS APRIL 29, PURCHASES AND DECEMBER 31, DECEMBER 31, INCLUDED IN NAME OF ISSUER 2005 AND ADDITIONS REDUCTIONS 2005 2005 TOTAL INCOME Neuberger Berman Prime Money Fund Trust Class** -- 7,629,326 5,948,932 1,680,394 $ 1,680,394 $ 13,171 </Table> * Affiliated issuers, as defined in the 1940 Act. ** Prime Money is also managed by Management 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. 16 <Page> FINANCIAL HIGHLIGHTS INTERNATIONAL PORTFOLIO The following table includes selected data for a share outstanding throughout the period and other performance information derived from the Financial Statements. <Table> <Caption> PERIOD FROM APRIL 29,^ TO DECEMBER 31, 2005 --------------- NET ASSET VALUE, BEGINNING OF PERIOD $ 10.00 --------------- INCOME FROM INVESTMENT OPERATIONS: NET INVESTMENT INCOME (LOSS)@ .07 NET GAINS OR LOSSES ON SECURITIES (BOTH REALIZED AND UNREALIZED) 1.67 --------------- TOTAL FROM INVESTMENT OPERATIONS 1.74 --------------- LESS DISTRIBUTIONS FROM NET INVESTMENT INCOME (.01) NET CAPITAL GAINS (.06) --------------- TOTAL DISTRIBUTIONS (.07) REDEMPTION FEES@ .01 --------------- NET ASSET VALUE, END OF PERIOD $ 11.68 --------------- TOTAL RETURN++ +17.50%** RATIOS/SUPPLEMENTAL DATA NET ASSETS, END OF PERIOD (IN MILLIONS) $ 12.6 RATIO OF GROSS EXPENSES TO AVERAGE NET ASSETS# 1.51%* RATIO OF NET EXPENSES TO AVERAGE NET Assets^^ 1.50%* RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS 0.91%* PORTFOLIO TURNOVER RATE 29%** </Table> See Notes to Financial Highlights 17 <Page> NOTES TO FINANCIAL HIGHLIGHTS INTERNATIONAL PORTFOLIO ++ 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.

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 audit. We conducted our audit 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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 International Portfolio, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, the results of its operations, changes in its net assets and financial highlights for the period from April 29, 2005 (commencement of operations) to December 31, 2005, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 19 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio manager. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the performance of the Fund since its inception relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board noted that the Fund had less than one year of performance. With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board did not consider the profitability of Management and its affiliates from their association with the Fund since the Fund began operations April 29, 2005. 29 <Page> The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds. The Board compared the fees charged to a comparable separate account to the fees charged to the Fund at various asset levels. The Board considered the appropriateness and reasonableness of the differences between the fees charged between the Fund and the comparable separate account and determined that the differences in fees were consistent with the management and other services provided. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 30 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST LIMITED MATURITY BOND PORTFOLIO(R) B1011 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 LIMITED MATURITY BOND PORTFOLIO Managers' Commentary The Neuberger Berman Advisers Management Trust (AMT) Limited Maturity Bond Portfolio provided a modestly positive return of 1.44% in calendar 2005. Throughout the year, the Federal Reserve continued to tighten monetary policy. These moves were largely anticipated, which early in the year resulted in relative stability for bond prices. However, in February, Fed Chairman Alan Greenspan unsettled bond investors with his much-quoted "conundrum" statement, expressing puzzlement that long-term bond yields were not responding to the Fed's short rate increases. These comments, along with other data, caused investors to fear more aggressive tightening, which put pressure on bond prices. This was followed by a rally in the beginning of the second quarter, as further data releases pointed to enough of a moderation in economic growth to hold inflation in check, and many observers believed that the Fed would maintain its "measured pace" of rate increases. Still, by October, the tide had turned yet again, and it appeared that the economy remained strong despite two major hurricanes and data suggesting that inflation would remain an ongoing concern. A modest December rally improved an otherwise poor year for the fixed income market. Over the course of 2005, long rates did not rise as much as they have historically during Fed tightening campaigns. In fact, the U.S. Treasury yield curve inverted at year-end, meaning that long-term bonds provided smaller yields than short-term bonds. The difference was slight, but the inversion is significant as it marks the first time this has happened since 2000. Throughout the year, we maintained a defensive posture, with portfolio duration (a standard measure of the sensitivity of a bond's price to interest rate movements) at slightly lower levels than those of our benchmark index. Our duration posture helped to protect the Portfolio from the impact of higher interest rates, and we made opportunistic sector allocations in order to enhance yield. We substantially reduced our allocation to Treasuries during the period, from 23.4% to 2.5%, and invested the proceeds in higher yielding but conservative alternatives. The changes included a significant increase in our allocation to AAA-rated asset-backed and mortgage-backed securities with well-defined maturities, from 13.9% of the Portfolio to 44%. During 2005, we increased the Portfolio's exposure to U.S. government agency securities from 10.7% to 12.2%, as these issues offer portfolio diversification and higher yields than Treasuries. We made strategic adjustments to our corporate bond holdings throughout the year based on our view of the economy and the markets, ending 2005 with the group representing roughly 40% of the Portfolio. Our commitment to protecting principal while enhancing yield has led us to focus on maintaining high credit-quality standards. Given the current economic environment, we decreased our allocation to BBB-rated securities, so that by fiscal year-end, most of the Portfolio was in AAA securities. At its December meeting, the Fed removed the reference to "accommodative" from its policy statement, and indicated that it is getting closer to the end of its tightening campaign. We expect rates to continue increasing, at least once or twice. The views of the Fed's board members regarding current and future policy remain varied. The data used by the Fed to dictate future policy decisions is also likely to stay mixed. We will therefore continue to maintain a defensive duration, and will only move to a more neutral stance on clearer signals from the Fed that an end to tightening is near. Corporate spreads remain historically narrow, so we are not being particularly aggressive in our reach for credit spread. We expect to continue to pick up yield while maintaining very high credit quality. In closing, our investment philosophy of research-driven security selection, opportunistic sector allocation and duration management has enabled us to provide our investors with consistent and secure returns, regardless of interest rates and market cycles. We are confident that this time-tested approach is in the best interest of our shareholders.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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.

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 Trust is currently comprised of twelve 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. 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 on settlement date. Fluctuations in the value of forward foreign currency contracts are recorded for financial reporting purposes as unrealized gains or losses by the Fund until the contractual settlement date. 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 12 <Page> total assets in foreign securities denominated in or indexed to 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, possibly at a time of rapidly declining prices, and/or a change in the value of the contract may not correlate with changes in the value of the underlying securities. For U.S. Federal income tax purposes, the futures transactions undertaken by the Fund may cause the Fund to recognize gains or losses from marking to market even though its positions have not been sold or terminated, may affect the character of the gains or losses recognized as long-term or short-term, and may affect the timing of some capital gains and losses realized by the Fund. Also, the Fund's losses on transactions involving futures contracts may be deferred rather than being taken into account currently in calculating the Fund's taxable income. During the year ended December 31, 2005, the Fund did not enter into any financial futures contracts. 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 distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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 13 <Page> 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, 2005, 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 expired capital loss carryover 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, 2005 and December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME TOTAL 2005 2004 2005 2004 $ 9,541,728 $ 11,800,669 $ 9,541,728 $ 11,800,669 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNREALIZED LOSS UNDISTRIBUTED APPRECIATION CARRYFORWARDS ORDINARY INCOME (DEPRECIATION) AND DEFERRALS TOTAL $ 11,873,795 $ (5,484,966) $ (20,848,894) $ (14,460,065) </Table> 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, 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, 2005, the Fund elected to defer $664,717 net capital losses arising between November 1, 2005 and December 31, 2005. 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, 2005, 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: <Table> <Caption> 2006 2007 2008 2012 2013 $ 2,478,607 $ 3,975,890 $ 6,386,624 $ 2,710,070 $ 4,632,986 </Table> 8 DISTRIBUTIONS TO SHAREHOLDERS: The Fund earns income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-date. 9 FOREIGN TAXES: Foreign taxes withheld represent amounts withheld by foreign tax authorities, net of refunds recoverable. 14 <Page> 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 Management 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. 15 <Page> The Fund retains Management as its investment manager under a Management Agreement. For such investment management services, the Fund pays Management a fee at the annual rate of 0.25% of the first $500 million of the Fund's average daily net assets, 0.225% of the next $500 million, 0.20% of the next $500 million, 0.175% of the next $500 million, and 0.15% of average daily net assets in excess of $2 billion. The Fund retains Management as its administrator under an Administration Agreement. The Fund pays Management an administration fee at the annual rate of 0.40% of its average daily net assets under this agreement. Additionally, Management retains State Street Bank and Trust Company ("State Street") as its sub-administrator under a Sub-Administration Agreement. Management pays State Street a fee for all services received under 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, 2005, 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, 2005, there was no reimbursement to Management under this agreement. At December 31, 2005, the Fund had no contingent liability to Management under this agreement. Management and Neuberger Berman, LLC ("Neuberger"), a member firm of the New York Stock Exchange and sub-adviser to the Fund, are 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, 2005, the impact of this arrangement was a reduction of expenses of $4,925. NOTE C--SECURITIES TRANSACTIONS: Cost of purchases and proceeds of sales and maturities of long-term securities (excluding short-term securities, financial futures contracts and foreign currency contracts) for the year ended December 31, 2005 were as follows: <Table> <Caption> SALES AND MATURITIES PURCHASES OF PURCHASES EXCLUDING SALES AND MATURITIES EXCLUDING U.S. GOVERNMENT U.S. GOVERNMENT OF U.S. GOVERNMENT U.S. GOVERNMENT AND AND AGENCY AND AGENCY AND AGENCY AGENCY OBLIGATIONS OBLIGATIONS OBLIGATIONS OBLIGATIONS $ 241,118,280 $ 214,006,737 $ 300,218,477 $ 126,567,864 </Table> 16 <Page> During the year ended December 31, 2005, the Fund entered into various contracts to deliver currencies at specified future dates.

Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit. 17 <Page> FINANCIAL HIGHLIGHTS Limited Maturity Bond Portfolio The following table includes selected data for a share outstanding throughout each year and other performance information derived from the Financial Statements. <Table> <Caption> YEAR ENDED DECEMBER 31, -------------------------------------------------------------- 2005 2004 2003 2002 2001 NET ASSET VALUE, BEGINNING OF YEAR $ 12.82 $ 13.20 $ 13.50 $ 13.47 $ 13.19 ---------- ---------- ---------- ---------- ---------- INCOME FROM INVESTMENT OPERATIONS: NET INVESTMENT INCOME (LOSS)+ .35 .30 .37 .53 .74~ NET GAINS OR LOSSES ON SECURITIES (BOTH REALIZED AND UNREALIZED) (.17) (.20) (.05) .16 .37~ ---------- ---------- ---------- ---------- ---------- TOTAL FROM INVESTMENT OPERATIONS .18 .10 .32 .69 1.11 ---------- ---------- ---------- ---------- ---------- LESS DISTRIBUTIONS FROM: NET INVESTMENT INCOME (.36) (.48) (.62) (.66) (.83) ---------- ---------- ---------- ---------- ---------- NET ASSET VALUE, END OF YEAR $ 12.64 $ 12.82 $ 13.20 $ 13.50 $ 13.47 ---------- ---------- ---------- ---------- ---------- TOTAL RETURN++ +1.44% +0.78% +2.42% +5.34% +8.78% RATIOS/SUPPLEMENTAL DATA NET ASSETS, END OF YEAR (IN MILLIONS) $ 341.3 $ 323.4 $ 306.4 $ 372.6 $ 292.8 RATIO OF GROSS EXPENSES TO AVERAGE NET ASSETS# .75% .73% .74% .76% .73% RATIO OF NET EXPENSES TO AVERAGE NET ASSETS .75% .73% .74% .76% .73% RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS 2.77% 2.28% 2.73% 4.01% 5.63%~ PORTFOLIO TURNOVER RATE 133% 132% 84% 120% 89% </Table> 18 <Page> NOTES TO FINANCIAL HIGHLIGHTS Limited Maturity Bond Portfolio ++ 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.

Accordingly, for the year ended December 31, 2001, the per share amounts and ratios shown decreased or increased as follows: <Table> <Caption> YEAR ENDED DECEMBER 31, 2001 Net Investment Income $ (.02) Net Gains or Losses on Securities $ .02 Ratio of Net Investment Income to Average Net Assets (.11%) </Table> 19 <Page> 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 Neuberger Berman Advisers Management Trust (the "Trust"), as of December 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the 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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 20 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the short-, intermediate-and long-term performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered long-term performance in relation to the degree of risk undertaken by the portfolio managers. The Board discussed the Fund's performance with Management and discussed steps that Management had taken, or intended to take, to improve the Fund's performance. The Board also considered Management's resources and responsiveness with respect to the Fund. With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. 30 <Page> The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds. The Board compared the fees charged to a comparable separate account to the fees charged to the Fund at various asset levels. The Board considered the appropriateness and reasonableness of the differences between the fees charged between the Fund and the comparable separate account and determined that the differences in fees were consistent with the management and other services provided. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 31 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST MID-CAP GROWTH PORTFOLIO(R) B1013 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 MID-CAP GROWTH PORTFOLIO MANAGERS' COMMENTARY The Neuberger Berman Advisers Management Trust (AMT) Mid-Cap Growth Portfolio generated a positive return in 2005, outperforming its benchmark, the Russell Midcap Growth Index. The Portfolio ranked in the top quartile of its Lipper peer group, as strong stock selection and sector allocation enhanced performance relative to the benchmark. Over the course of the year, impressive corporate earnings gains, a strong economy and healthy profit margins supported equity performance but were offset by the Federal Reserve's relentless increases in short-term interest rates. Energy was the best performing sector, reflecting record highs in crude oil prices due to increased Asian demand and a strong U.S. economy. Sectors tied to the consumer were generally the weakest of the year as personal income was squeezed by higher energy costs and interest rates. For the Portfolio, the most significant contributors to performance were securities in the Health Care and Financial sectors. Among Health Care holdings, Celgene was a particularly strong performer. Financial stocks that did well included business services names such as Chicago Mercantile Exchange and brokerage issues such as Legg Mason. Our security selection in the Energy sector was helpful, with Peabody Energy and Canadian Natural Resources providing strong performance. Consumer Staples holdings such as Whole Foods Market and Constellation Brands also bolstered results. Finally, our sector allocation was a positive, as overweights in Telecom and Energy -- two of the best performing sectors of the year -- provided favorable returns. Stock selection within Information Technology had the most negative impact on relative performance. Within this sector, various software companies showed weakness, while some business services companies also underperformed. Moving forward, we believe that domestic consumers remain financially stretched. Real wage growth has been non-existent this economic cycle. Instead, consumer spending has been driven by strong housing gains and additional debt. Housing now contributes over 6% of GDP and is showing signs of slowing. Housing inventories are at a nine-year high and affordability has hit a new low. We do not expect a housing price collapse, but this major support for consumer spending is weakening, which could slow economic activity. Although data are somewhat ambiguous, there is evidence that U.S. economic growth is slowing. In contrast, foreign economies in Asia, Japan and even Europe are exhibiting increased economic activity. As such, we want the Portfolio to be tilted toward beneficiaries of global economic expansion and corporate spending and away from exposure to the beleaguered American consumer. Throughout 2005, there was little change in our strategic position. However, at some point in the months ahead we expect to become more defensive and move up the market capitalization spectrum. For now, we want to let the past market leadership play out before making a change. If, as we expect, the market moves higher in the first part of the year, we currently anticipate making rotational changes into more traditional growth areas. Currently, Energy, Information Technology, Telecom and Health Care are all overweighted in the Portfolio while Consumer Staples and Discretionary, Utilities and Financials remain underweighted.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $491,225,026. Gross unrealized appreciation of investments was $194,869,437 and gross unrealized depreciation of investments was $3,578,156, resulting in net unrealized appreciation of $191,291,281, based on cost for U.S. Federal income tax purposes. * Non-income producing security. ^ All or a portion of this security is on loan (see Note A of Notes to Financial Statements). ++ Managed by an affiliate of Neuberger Berman Management Inc. and could be deemed an affiliate of the Fund (see Notes A & F of Notes to Financial Statements). @ Neuberger Berman Prime Money Fund ("Prime Money") is also managed by Neuberger Berman Management Inc.

-------------------------------------------------------------------------------------------------------- </Table> See Notes to Financial Statements 10 <Page> 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 twelve 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. 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 <Page> Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, 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, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNREALIZED LOSS APPRECIATION CARRYFORWARDS (DEPRECIATION) AND DEFERRALS TOTAL $ 191,291,192 $ (307,675,623) $ (116,384,431) </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales and capital loss carryforwards. 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, 2005, the Fund had unused capital loss carryforwards available for Federal income tax purposes to offset net realized capital gains, if any, as follows: <Table> <Caption> EXPIRING IN: 2009 2010 2011 $ 183,193,083 $ 113,423,118 $ 11,059,422 </Table> 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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 <Page> 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 ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $145,972. Effective October 4, 2005, the Fund entered into new securities lending arrangements using a third party, eSecLending, to secure bids. Pursuant to such arrangements, eSecLending currently acts as agent for the Fund arranging principals to guarantee a certain amount of revenue to the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income from the lending program represents income earned on the cash collateral and the guaranteed amount, less fees and expenses associated with the loans. These amounts are reflected in the Statement of Operations under the caption "Income from securities loaned (affiliated issuers)." 10 REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements with institutions that Management 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives 13 <Page> from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $16,859 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $653,782 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 14 <Page> 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 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 the Fund's average daily net assets (the "Expense Limitation"). For the year ended December 31, 2005, 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 Limitation, and the repayments are made within three years after the year in which Management issued the reimbursement. During the year ended December 31, 2005, there was no reimbursement to Management under these agreements. At December 31, 2005, the Fund's Class I and Class S shares had no contingent liability to Management under these agreements. Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $61,212. The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $3,753. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $362,097,870 and $346,580,351, respectively. 15 <Page> During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $951,510, of which Neuberger received $893, Lehman received $147,094, and other brokers received $803,523. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the years ended December 31, 2005 and December 31, 2004 was as follows: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, 2005 2004 SHARES SHARES SHARES SHARES SOLD REDEEMED TOTAL SOLD REDEEMED TOTAL CLASS I 4,494,861 (4,283,550) 211,311 5,076,695 (4,607,909) 468,786 CLASS S 524,981 (234,759) 290,222 672,353 (237,618) 434,735 </Table> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit. 16 <Page> NOTE F--INVESTMENTS IN AFFILIATES*: <Table> <Caption> INCOME FROM INVESTMENTS BALANCE OF BALANCE OF IN SHARES GROSS SHARES AFFILIATED HELD GROSS SALES HELD VALUE ISSUERS DECEMBER 31, PURCHASES AND DECEMBER 31, DECEMBER 31, INCLUDED IN NAME OF ISSUER 2004 AND ADDITIONS REDUCTIONS 2005 2005 TOTAL INCOME Neuberger Berman Securities Lending Quality Fund, LLC** 125,896,400 2,984,147,318 3,073,085,017 36,958,701 $ 36,958,701 $ 616,687 Neuberger Berman Prime Money Fund Trust Class*** 30,889,296 256,971,194 262,198,865 25,661,625 25,661,625 653,782 ------------- ------------ TOTAL $ 62,620,326 $ 1,270,469 ------------- ------------ </Table> * Affiliated issuers, as defined in the 1940 Act. ** Prior to February 7, 2005, the Old Fund, an investment vehicle established by the Fund's custodian, was used to invest cash the Fund received as collateral for securities loans.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 20 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the short-, intermediate- and long-term performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered long-term performance in relation to the degree of risk undertaken by the portfolio managers. The Board discussed the Fund's performance with Management and discussed steps that Management had taken, or intended to take, to improve the Fund's performance. The Board also considered Management's resources and responsiveness with respect to the Fund. 30 <Page> With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board compared the fees charged to a comparable sub-advised fund and a comparable separate account to the fees charged to the Fund at various asset levels. The Board considered the appropriateness and reasonableness of the differences between the fees charged between the Fund and the comparable sub-advised fund and separate account and determined that the differences in fees were consistent with the management and other services provided. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; that it retained confidence in Management's and Neuberger's capabilities to manage the Fund; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 31 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST PARTNERS PORTFOLIO(R) B1010 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 PARTNERS PORTFOLIO MANAGER'S COMMENTARY Despite a strong economy and excellent corporate earnings growth, large-cap stocks made only modest progress in 2005. Absent the exceptional performance of energy stocks and several interest rate sensitive sectors such as Homebuilding and Utilities, equity returns would have been even more uninspiring. We are pleased to report that, in this challenging stock market, the Neuberger Berman Advisers Management Trust (AMT) Partners Portfolio delivered generous returns, outperforming its S&P 500 and Russell 1000 Value Index benchmarks by a wide margin. Sector allocation, most notably a substantial overweighting in Energy, contributed to relative results. However, stock selection provided an even greater benefit as Portfolio holdings outperformed in seven of ten sectors versus the S&P 500. Energy investments made the largest contribution to absolute and relative performance. The Portfolio was overweighted in Energy versus the S&P 500 and nearly double-weighted versus the Russell 1000 Value Index. In addition, the Portfolio's Energy holdings significantly outperformed both benchmarks' Energy sector components. Non-conventional energy companies such as oil sands producer Canadian Natural Resources, the single largest contributor to returns, and coal miners Peabody Coal and Arch Coal, the Portfolio's second and third biggest contributors, enhanced returns in this sector. Exploration and production companies Talisman Energy and XTO Energy were also outstanding performers. Our success in Consumer Discretionary, the S&P 500's worst performing sector but the Portfolio's second best performing sector of the year (by impact), was driven purely by stock selection, with homebuilders KB Homes, Centex, and Pulte Homes, and retailer J.C. Penney posting large gains. Health Care holdings continued to contribute to returns, with HMOs such as Aetna and Pacific Care (acquired by UnitedHealth Group), and pharmacy benefit managers, most notably Express Scripts and Caremark, providing strong performance. Relative performance was also enhanced by our avoidance of troubled large pharmaceutical companies. Although the Portfolio had limited exposure to the Materials sector, our investment in leading copper producer Phelps Dodge delivered a substantial gain. In contrast, Information Technology holdings penalized returns, with computer printer manufacturer Lexmark and security software producer Veritas Software appearing on our bottom-ten performance list. Lexmark was hurt by increased competition from Hewlett Packard and although Veritas had been a long-term winner for us, it retreated this year when it was acquired by Symantec at a price well below initial expectations. Although in aggregate the Portfolio's Financial holdings had positive returns, they materially underperformed S&P 500 sector components. Even with the exceptional performance of energy stocks in 2005, we still favor those companies whose valuations fail to reflect prices supported by the demand-driven supply imbalances in the sector. We expect strong demand from developed and emerging market nation manufacturers to continue to benefit select materials companies. With profit margins expanding due to productivity gains, industrial stocks should also do well. We are cool on technology due to the negative impact that expensing stock options will have on earnings this year and our concern that capital spending on technology will fall short of expectations. We are also being cautious in the financial sector, where spread oriented businesses like banking may continue to suffer from a flat yield curve. Looking ahead, we are relatively bullish on the outlook for stocks. Over much of the last two years, equity returns have been muted by concern that expensive energy and an extended tightening cycle by the Federal Reserve would undermine economic and corporate earnings growth. The economy adjusted to higher energy prices and rising short-term interest rates without losing traction. Ongoing productivity gains have continued to support better-than-expected 1 <Page> earnings growth. In the year ahead, we expect the economy to continue to expand at a 3-4% pace and are looking for S&P 500 earnings growth in the high single-digit to low double-digit percentage range. We also believe that after contracting for two years, price/earnings multiples may expand as investor sentiment improves, perhaps as a result of the Federal Reserve shifting into neutral.

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(R) Index measures the performance of the 1,000 largest companies in the Russell 3000(R) 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.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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.

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, including securities for which the necessary last sale, asked and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $592,792,478. Gross unrealized appreciation of investments was $169,876,692 and gross unrealized depreciation of investments was $9,248,648, resulting in net unrealized appreciation of $160,628,044, based on cost for U.S. Federal income tax purposes. * Non-income producing security. ^^ All or a portion of this security is on loan (see Note A of Notes to Financial Statements). ++ Managed by an affiliate of Neuberger Berman Management Inc. and could be deemed an affiliate of the Fund (see Notes A & F 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.

----------------------------------------------------------------------------------------------------------------------- </Table> See Notes to Financial Statements 10 <Page> 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 twelve 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, 2005 was $2,623. 11 <Page> 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. Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, 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, 2005 and December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME LONG-TERM CAPITAL GAIN TOTAL 2005 2004 2005 2004 2005 2004 $ 6,487,803 $ 62,733 $ 150,568 $ -- $ 6,638,371 $ 62,733 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNDISTRIBUTED UNDISTRIBUTED UNREALIZED LOSS ORDINARY LONG-TERM APPRECIATION CARRYFORWARDS INCOME GAIN (DEPRECIATION) AND DEFERRALS TOTAL $ 11,892,732 $ 61,775,244 $ 160,627,875 $ -- $ 234,295,85 </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales. 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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 <Page> 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 Management 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 ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $77,928. Effective October 4, 2005, the Fund entered into new securities lending arrangements using a third party, eSecLending, to secure bids. Pursuant to such arrangements, eSecLending currently acts as agent for the Fund, arranging principals to guarantee a certain amount of revenue to the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income from the lending program represents income earned on the cash collateral and the guaranteed amount, less fees and expenses associated with the loans. These amounts are reflected in the Statement of Operations under the caption "Income from securities loaned (affiliated issuers)." 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 a money 13 <Page> market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $7,011 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $265,491 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, 2005, no reimbursement to the Fund was required. The Fund has agreed to repay 14 <Page> 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, 2005, there was no reimbursement to Management under this agreement. At December 31, 2005, the Fund had no contingent liability to Management under this agreement. Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $84,418. The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $7,302. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $415,548,792 and $375,102,560, respectively. During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $921,676, of which Neuberger received $329, Lehman received $161,237, and other brokers received $760,110. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the years ended December 31, 2005 and December 31, 2004 was as follows: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, 2005 2004 SHARES SOLD 7,805,132 4,246,276 SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS 337,316 3,906 SHARES REDEEMED (6,137,955) (15,536,771) ---------- ----------- TOTAL 2,004,493 (11,286,589) ---------- ----------- </Table> 15 <Page> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 19 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio manager. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the short-, intermediate- and long-term performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered long-term performance in relation to the degree of risk undertaken by the portfolio manager. With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. 29 <Page> The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds or separate accounts. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; the performance of the Fund was satisfactory over time; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 30 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST REGENCY PORTFOLIO B1012 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 REGENCY PORTFOLIO Manager's Commentary Mid-cap value stocks excelled in 2005, with the Russell Midcap Value Index returning 12.65% compared to the large-cap S&P 500's 4.91% and the small-cap Russell 2000's 4.55%. For the year, the Neuberger Berman Advisers Management Trust (AMT) Regency Portfolio slightly underperformed its Russell Midcap Value benchmark, despite an overweight in Energy--by far the best performing market sector--and the superior relative performance of its Health Care holdings. Although Energy sector holdings modestly underperformed benchmark sector components, the Portfolio's substantial overweight in this top performing sector made the largest contribution to absolute and relative returns. Exploration and production company XTO Energy finished at the top of our performance contributors list; refiner/distributor Sunoco was the fourth biggest contributor; and non-conventional energy stocks such as Canadian oil sands producer Canadian Natural Resources and coal mining company Arch Coal also finished in our top ten. The Portfolio was overweight in Health Care, and our stock selection in this sector had the most favorable impact on returns. Omnicare, a leading drug distributor to nursing homes, and HMO Coventry Health Care were our second and third biggest performance contributors. Industrials sector investments, most notably construction and mining equipment manufacturer Joy Global, also buoyed returns. The Portfolio had minimal exposure to the Materials sector. However, our lone holding in the sector, leading copper producer Phelps Dodge, performed exceptionally well as the price of copper rose. The Portfolio was underweighted in Consumer Staples, but the sharp sell-off in NTBY, one of the Portfolio's larger holdings in the sector, penalized returns. A leading manufacturer, wholesaler, and retailer of vitamins and nutritional supplements under the brand names Nature's Bounty, Sundown and American Health, NTBY was hurt by the medical controversy surrounding Vitamin D. The Portfolio's substantial overweight in the Consumer Discretionary sector, the worst performing sector in the Russell Midcap Value Index, negatively affected performance. Retailers Dollar Tree Stores and Pier 1 Imports and auto seating company Lear Corp. finished near the bottom of our performance charts. We sold Pier 1 and Lear at mid-year, but not before the stocks undermined full-year performance. The Portfolio's significant underweight in Utilities--the year's third best performing sector--also detracted from relative returns. Despite this year's exceptional performance, we believe that select energy stocks still offer good value. Current valuations seem to imply that energy prices will fall substantially from present levels. In view of what we perceive to be a lasting change in supply/demand dynamics, we think that energy prices will remain relatively firm and that energy company earnings will continue to grow. We also like the prospects for industrial companies, which should continue to benefit from synchronized global growth and expanding profit margins resulting from ongoing productivity gains. We are less than enthusiastic about technology, because of the negative impact that expensing stock options will have on many tech companies' earnings and our concern that technology capital spending may not meet consensus expectations. We are also treading carefully in the financial sector, because we believe that interest-rate-spread oriented businesses like banking will continue to suffer from a flat yield curve. Looking ahead, we are relatively bullish on the prospects for stocks. Earnings growth has outpaced share price advances for several years, in the process making equity valuations more attractive. The economy has adjusted relatively well to expensive energy and higher short-term interest rates and we expect to see Gross Domestic Product (GDP) growth in the 3-4% range in 2006, with earnings growing at high single-digit to low double-digit percentage rates. In our view, this would be a favorable economic scenario for stocks. If investor sentiment improves, perhaps as a result of the Federal Reserve shifting into neutral, we think that price/earnings multiples could expand, enhancing earnings-driven equity returns.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION AS OF 12/31/05 (UNAUDITED) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST REGENCY PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS I $ 1,000 $ 1,084.80 $ 5.36 CLASS S $ 1,000 $ 1,085.20 $ 6.46 HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** CLASS I $ 1,000 $ 1,020.06 $ 5.19 CLASS S $ 1,000 $ 1,019.00 $ 6.26 </Table> * 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 184/365 (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 period divided by 365. 4 <Page> SCHEDULE OF INVESTMENTS Regency Portfolio <Table> <Caption> NUMBER OF SHARES MARKET VALUE + COMMON STOCKS (98.4%) AUTO RELATED (5.7%) 88,950 Advance Auto Parts $ 3,865,767* 29,400 BorgWarner, Inc. 1,782,522 66,100 Harley-Davidson 3,403,489^^ 51,300 Johnson Controls 3,740,283 --------------- 12,792,061 BANKING & FINANCIAL (6.3%) 75,400 Astoria Financial 2,216,760^^ 53,600 First Horizon National 2,060,384^^ 344,900 Hudson City Bancorp 4,180,188 87,100 IndyMac Bancorp 3,398,642^^ 82,065 North Fork Bancorp 2,245,298 --------------- 14,101,272 BUILDING, CONSTRUCTION & FURNISHING (13.1%) 46,500 Beazer Homes USA 3,387,060^^ 75,300 Centex Corp. 5,383,197 93,600 Hovnanian Enterprises 4,646,304*^^ 58,500 KB HOME 4,250,610 74,300 Lennar Corp. 4,533,786 4,700 NVR, Inc. 3,299,400*^^ 102,200 Pulte Homes 4,022,592^^ --------------- 29,522,949 BUSINESS SERVICES (2.4%) 99,300 Career Education 3,348,396* 45,700 Manpower Inc. 2,125,050 --------------- 5,473,446 CAPITAL EQUIPMENT (2.1%) 117,450 Joy Global 4,698,000 COAL (5.4%) 132,000 Alpha Natural Resources 2,535,720*^^ 64,700 Arch Coal 5,143,650 55,000 Peabody Energy 4,533,100 --------------- 12,212,470 COMMUNICATIONS EQUIPMENT (1.2%) 243,200 Avaya Inc. 2,594,944* CONSUMER CYCLICALS (1.5%) 41,200 Whirlpool Corp. 3,450,912 CONSUMER PRODUCTS & SERVICES (1.2%) 134,100 Spectrum Brands 2,723,571*^^ ELECTRIC UTILITIES (1.5%) 116,400 DPL Inc. 3,027,564 6,100 NRG Energy 287,432* --------------- 3,314,996 ENERGY (10.3%) 112,700 Canadian Natural Resources 5,592,174 33,600 Sunoco, Inc. 2,633,568 94,300 Talisman Energy 4,986,584 96,800 TXU Corp. 4,858,392 116,276 XTO Energy 5,109,168 --------------- 23,179,886 FINANCIAL SERVICES (3.6%) 30,200 Ambac Financial Group $ 2,327,212 28,600 Bear Stearns 3,304,158 49,500 CIT Group 2,563,110 --------------- 8,194,480 FOOD & BEVERAGE (1.1%) 98,900 Constellation Brands 2,594,147* HEALTH CARE (5.7%) 59,400 Coventry Health Care 3,383,424*^^ 163,300 NBTY, Inc. 2,653,625*^^ 50,000 Omnicare, Inc. 2,861,000 53,200 Triad Hospitals 2,087,036* 24,100 WellPoint Inc. 1,922,939* --------------- 12,908,024 INDUSTRIAL (1.0%) 87,400 Chicago Bridge & Iron 2,203,354 INSURANCE (4.7%) 34,400 Arch Capital Group 1,883,400* 76,600 Endurance Specialty Holdings 2,746,110 83,200 PMI Group 3,417,024 43,100 Radian Group 2,525,229 --------------- 10,571,763 MACHINERY & EQUIPMENT (1.9%) 72,400 Terex Corp. 4,300,560* MANUFACTURING (2.9%) 54,400 Briggs & Stratton 2,110,176 30,700 Eaton Corp. 2,059,663 57,300 Ingersoll-Rand 2,313,201^^ --------------- 6,483,040 METALS (1.9%) 29,700 Phelps Dodge 4,272,939 OIL & GAS (4.8%) 170,800 Denbury Resources 3,890,824* 94,900 Quicksilver Resources 3,986,749*^^ 80,100 Southwestern Energy 2,878,794* --------------- 10,756,367 PHARMACEUTICAL (1.2%) 70,600 Shire PLC ADR 2,738,574 REAL ESTATE (4.0%) 52,600 Colonial Properties Trust 2,208,148^^ 69,600 Developers Diversified Realty 3,272,592 57,100 iStar Financial 2,035,615 70,300 Trizec Properties 1,611,276 --------------- 9,127,631 RETAIL (5.7%) 56,400 Aeropostale, Inc. 1,483,320* 73,100 Foot Locker 1,724,429^^ 119,200 Hot Topic 1,698,600*^^ 49,700 Jones Apparel Group 1,526,784 104,900 Ross Stores 3,031,610^^ 146,700 TJX Cos. 3,407,841^^ --------------- 12,872,584 </Table> See Notes to Schedule of Investments 5 <Page> <Table> <Caption> NUMBER OF SHARES MARKET VALUE + SEMICONDUCTORS (0.9%) 62,300 International Rectifier $ 1,987,370* SOFTWARE (1.8%) 92,300 Activision, Inc. 1,268,202* 140,000 Check Point Software Technologies 2,814,000* --------------- 4,082,202 TECHNOLOGY (0.9%) 47,300 Lexmark International Group 2,120,459* TELECOMMUNICATIONS (0.5%) 37,100 Amdocs Ltd. 1,020,250* TRANSPORTATION (4.1%) 66,000 Frontline Ltd.

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, including securities for which the necessary last sale, asked, and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $236,589,903. Gross unrealized appreciation of investments was $31,864,202 and gross unrealized depreciation of investments was $7,066,774, resulting in net unrealized appreciation of $24,797,428, based on cost for U.S. Federal income tax purposes. * Non-income producing security. ^^ All or a portion of this security is on loan (see Note A of Notes to Financial Statements). ++ Managed by an affiliate of Neuberger Berman Management Inc. and could be deemed an affiliate of the Fund (see Notes A & F 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 Trust is currently comprised of twelve 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 April 29, 2005, 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. 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 11 <Page> companies and to distribute substantially all of its earnings to its shareholders. Therefore, no Federal income or excise tax provision is required. Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, 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, 2005 and December 31, 2004 was as follows: <Table> <Caption> DISTRIBUTIONS PAID FROM: ORDINARY INCOME LONG-TERM CAPITAL GAIN TAX RETURN OF CAPITAL TOTAL 2005 2004 2005 2004 2005 2004 2005 2004 $ 4,451,514 $ 27,438 $ 8,209,556 $ -- $ -- $ -- $ 12,661,070 $ 27,438 </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNDISTRIBUTED UNDISTRIBUTED UNREALIZED LOSS ORDINARY LONG-TERM APPRECIATION CARRYFORWARDS INCOME GAIN (DEPRECIATION) AND DEFERRALS TOTAL $ 2,740,826 $ 12,728,401 $ 24,797,372 $ -- $ 40,266,599 </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales. 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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 <Page> 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 ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $107,955. Effective September 13, 2005, the Fund entered into new securities lending arrangements using a third party, eSecLending, to secure bids. Pursuant to such arrangements, eSecLending currently acts as agent for the Fund, arranging principals to guarantee a certain amount of revenue to the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income from the lending program represents income earned on the cash collateral and the guaranteed amount, less fees and expenses associated with the loans. These amounts are reflected in the Statement of Operations under the caption "Income from securities loaned (affiliated issuers)." 10 REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements with institutions that Management 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 a money market fund managed by Management or an affiliate. The Fund invests in the Neuberger Berman Prime Money Fund ("Prime Money"), as approved by the Board. Prime Money seeks to provide the highest 13 <Page> available current income consistent with safety and liquidity. For any cash that the Fund invests in Prime Money, Management waives a portion of its management fee equal to the management fee it receives from Prime Money on those assets (the "Arrangement"). For the year ended December 31, 2005, management fees waived under this Arrangement amounted to $5,926 and is reflected in the Statement of Operations under the caption "Investment management fee waived." For the year ended December 31, 2005, income earned under this Arrangement amounted to $228,552 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 <Page> 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 to reimburse the Fund's Class I and Class S shares for their operating expenses (including the fees payable to Management but excluding interest, taxes, brokerage commissions, extraordinary expenses, and transaction costs) ("Operating Expenses") which exceed the expense limitation as detailed in the following table: <Table> <Caption> REIMBURSEMENT FROM MANAGEMENT FOR THE EXPENSE YEAR ENDED LIMITATION(1) EXPIRATION DECEMBER 31, 2005 CLASS I 1.50% 12/31/08 -- CLASS S 1.25% 12/31/15 $ 954 </Table> (1) Expense limitation per annum of the respective class' average daily net assets. Each respective class has agreed to repay Management 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, 2005, there was no reimbursement to Management under these agreements. At December 31, 2005, contingent liabilities to Management under these agreements were as follows: <Table> <Caption> EXPIRING IN: 2008 CLASS S $ 954 </Table> Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are wholly-owned subsidiaries of Lehman Brothers Holdings Inc. ("Lehman"), a publicly-owned holding company. Neuberger is retained by Management to furnish it with investment recommendations and research information without added cost to the Fund. Several individuals who are officers and/or Trustees of the Trust are also employees of Neuberger and/or Management. The Fund has 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, 2005, the impact of this arrangement was a reduction of expenses of $16,534. 15 <Page> The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $485. On June 6, 2005, Management voluntarily agreed to reimburse the Fund for all brokerage commissions from June 6, 2005 to July 20, 2005, to facilitate a restructuring of the portfolio following a change in the Fund's portfolio manager. The amount of this voluntary reimbursement was $8,007. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $214,221,315 and $147,916,702, respectively. During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $274,191, of which Neuberger received $43, Lehman received $44,943, and other brokers received $229,205. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the period ended December 31, 2005 and for the year ended December 31, 2004 was as follows: FOR THE PERIOD ENDED DECEMBER 31, 2005* <Table> <Caption> SHARES ISSUED ON REINVESTMENT OF DIVIDENDS SHARES AND SHARES SOLD DISTRIBUTIONS REDEEMED TOTAL Class I 4,719,428 895,408 (752,587) 4,862,249 Class S 301,375 -- (14,871) 286,504 </Table> FOR THE YEAR ENDED DECEMBER 31, 2004 <Table> <Caption> SHARES ISSUED ON REINVESTMENT OF DIVIDENDS SHARES AND SHARES SOLD DISTRIBUTIONS REDEEMED TOTAL Class I 6,495,897 2,128 (2,081,049) 4,416,976 </Table> * For the year ended December 31, 2005 for Class I. For the period from April 29, 2005 (commencement of operations) to December 31, 2005 for Class S. NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on 16 <Page> the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 20 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio manager. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered performance in relation to the degree of risk undertaken by the portfolio manager. With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. 30 <Page> The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. The Board noted that the Fund's actual management fee was higher than the peer group median for one class of the Fund. The Board considered whether specific portfolio management or administration needs contributed to the higher fee. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual limit on Fund expenses undertaken by Management for each class of the Fund. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board compared the fees charged to comparable sub-advised funds and a comparable separate account to the fees charged to the Fund at various asset levels. The Board considered the appropriateness and reasonableness of the differences between the fees charged between the Fund and the comparable sub-advised funds and separate account and determined that the differences in fees were consistent with the management and other services provided. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; the performance of the Fund was satisfactory over time; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 31 <Page> [NEUBERGER BERMAN LOGO] A LEHMAN BROTHERS COMPANY ANNUAL REPORT DECEMBER 31, 2005 NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST SOCIALLY RESPONSIVE PORTFOLIO(R) B1017 02/06 <Page> NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST DECEMBER 31, 2005 SOCIALLY RESPONSIVE PORTFOLIO MANAGERS' COMMENTARY Despite better-than-expected Gross Domestic Product (GDP) growth and impressive corporate earnings gains, equity returns in 2005 were relatively modest, as investors worried that expensive energy and rising short-term interest rates could hurt the economy and restrain future earnings growth. Market performance was relatively narrow, as only a few sectors and industry groups -- most notably Energy and interest-rate-sensitive businesses such as Homebuilding and Utilities - -- were responsible for the lion's share of stock returns. We are pleased to report that the Neuberger Berman Advisers Management Trust (AMT) Socially Responsive Portfolio posted a respectable return in this uninspiring market, outperforming the S&P 500 and modestly trailing the Russell 1000 Value Index despite being underweighted in the stock market's hottest sectors. Stock selection was responsible for the Portfolio's superior relative returns, as our holdings outperformed benchmark components in seven of ten market sectors. Although the Portfolio was underweighted in Energy, investments in the sector delivered favorable relative returns. Exploration and production company Newfield Exploration was the only Energy company on our top-ten performance list, but all of the Portfolio's Energy holdings posted solid gains. The Portfolio was equal-weighted in Health Care, but holdings more than tripled the return of S&P 500 Health Care components. Long time industry favorite UnitedHealth Group once again led the way, with Millipore also posting a strong gain. The Portfolio was neutral-weighted in Financials, but the strong performance of stocks such as Goldman Sachs, State Street Corp. and AMB Property Corp. enhanced relative returns. Industrial sector holdings, most notably Canadian National Railway, also contributed to relative performance. In aggregate, the Portfolio's Information Technology investments posted a modest loss in 2005. We had winners such as Texas Instruments and National Instruments, which were among our best performers, and losers such as Dell, Teradyne and Altera, which were among our biggest disappointments. After suffering large losses following the bursting of the Internet bubble in 2000, investors remain skittish about technology stocks. When things go right for a tech company, it generates a great deal of excitement. However, at the first hint of any trouble, many investors rush to the exits. As long-term investors, we don't operate that way and are often on the other side of the "momentum" players. If we are confident a company is well positioned to benefit from secular as well as cyclical trends, we will be patient holders and use stock market volatility to add to an existing position or to introduce a new company to the Portfolio. With this in mind, in 2005 we were comfortable holding "best of breed" tech companies such as Dell, Teradyne and Altera, as our research suggested that longer-term fundamentals for their businesses remained favorable. Our Consumer Discretionary investments outperformed benchmark sector components, but in aggregate posted a modest decline for the year. The Portfolio benefited from owning two of the best performing stocks in the troubled auto business, Toyota Motor Corp. and BorgWarner, Inc. Gains in these stocks helped offset losses in media holdings such as Liberty Media and Comcast Corp. Finally, the Portfolio's substantial underweighting in Utilities, the stock market's second best performing sector, penalized relative returns. Looking ahead, despite concern that we may see more inflation than is currently anticipated or experience a geopolitical event that would destabilize the global economy, we feel relatively positive about the prospects for stocks. We think that the economy will continue to expand and that corporate earnings will continue to grow at a decent pace. With stock price gains significantly lagging earnings growth over the last two years, in general, equity valuations are more attractive. Also, because most sectors have moved sideways over the past year, we are finding what we believe to be excellent value-oriented opportunities in a wide range of industry groups. This makes it easier for us to buy the very best socially responsive companies in their respective industries at opportunistic prices. Sincerely, /s/ Arthur Moretti /s/ Ingrid S.

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(R) Index measures the performance of the 1,000 largest companies in the Russell 3000(R) 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.

All mutual funds incur operating expenses, which include management fees, fees for administrative services and costs of shareholder reports, among others. The following examples are 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: <Table> ACTUAL EXPENSES AND PERFORMANCE: The first section of the table provides information about actual account values and actual expenses in dollars, based on the fund's actual performance during the period. You may use the information in this line, together with the amount you invested, to estimate the expenses you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section of the table under the heading entitled "Expenses Paid During the Period" 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 the expenses shown in this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. </Table> EXPENSE INFORMATION AS OF 12/31/05 (UNAUDITED) NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST SOCIALLY RESPONSIVE PORTFOLIO <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACTUAL ACCOUNT VALUE ACCOUNT VALUE DURING THE PERIOD* CLASS I $ 1,000 $ 1,091.20 $ 6.80 HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES)** CLASS I $ 1,000 $ 1,018.70 $ 6.56 </Table> * Expenses are equal to the expense ratio for the class, multiplied by the average account value over the period, multiplied by 184/365 (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 365. 4 <Page> SCHEDULE OF INVESTMENTS SOCIALLY RESPONSIVE PORTFOLIO <Table> <Caption> NUMBER OF SHARES MARKET VALUE+ COMMON STOCKS (95.0%) AUTOMOTIVE (5.2%) 19,525 BorgWarner, Inc. $ 1,183,801 13,825 Toyota Motor Corp.

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, including securities for which the necessary last sale, asked and/or bid prices are not readily available, by methods the Board of Trustees of Neuberger Berman Advisers Management Trust (the "Board") has approved on the belief that they reflect fair value. Numerous factors may be considered when determining the fair value of a security, including available analyst, media or other reports, trading in futures or ADRs and whether the issuer of the security being fair valued has other securities outstanding. Foreign security prices are furnished by independent quotation services expressed in local currency values. Foreign security prices are translated from the local currency into U.S. dollars using the exchange rate as of 12:00 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 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. In this event, FT Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. 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, 2005, the cost of investments for U.S. Federal income tax purposes was $46,220,072. Gross unrealized appreciation of investments was $5,126,675 and gross unrealized depreciation of investments was $734,267, resulting in net unrealized appreciation of $4,392,408, based on cost for U.S. Federal income tax purposes. * Non-income producing security.

The Trust is currently comprised of twelve 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 shareholders. Therefore, no Federal income or excise tax provision is required. 10 <Page> Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. 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, 2005, 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. The tax character of distributions paid during the years ended December 31, 2005 and December 31, 2004 was as follows: DISTRIBUTIONS PAID FROM: <Table> <Caption> ORDINARY INCOME LONG-TERM CAPITAL GAIN TOTAL 2005 2004 2005 2004 2005 2004 $ -- $ -- $ 93,682 $ -- $ 93,682 $ -- </Table> As of December 31, 2005, the components of distributable earnings (accumulated losses) on a U.S. Federal income tax basis were as follows: <Table> <Caption> UNDISTRIBUTED UNREALIZED LOSS UNDISTRIBUTED LONG-TERM APPRECIATION CARRYFORWARDS ORDINARY INCOME GAIN (DEPRECIATION) AND DEFERRALS TOTAL $ 200,953 $ 1,098,578 $ 4,392,280 $ -- $ 5,691,811 </Table> The difference between book basis and tax basis distributable earnings is attributable primarily to timing differences of wash sales and return of capital distributions from real estate investment trusts. 6 DISTRIBUTIONS TO SHAREHOLDERS: The Fund may earn income, net of expenses, daily on its investments. Distributions from net investment income and net realized capital gains, if any, generally are distributed in October. Income distributions and capital gain distributions to shareholders are recorded on the ex-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 <Page> 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 ("Neuberger Agreement") on July 1, 2004 with Neuberger Berman, LLC ("Neuberger"), an affiliate of the Fund, pursuant to which Neuberger acted as the Fund's lending agent. Under the Neuberger Agreement, Neuberger guaranteed a certain amount of revenue to the Fund and received any revenue earned in excess of the guaranteed amount as a lending agency fee. For the year ended December 31, 2005, Neuberger received revenue under the Neuberger Agreement of $2,974. Effective October 4, 2005, eSecLending acts as agent for the Fund. Under the Neuberger Agreement and the new securities lending arrangements, the Fund receives cash collateral at the beginning of each transaction equal to at least 102% of the prior day's market value of the loaned securities (105% in the case of international securities). Prior to February 7, 2005, the Fund invested the cash collateral in the N&B Securities Lending Quality Fund, LLC ("Old Fund"), which was managed by State Street Bank and Trust Company ("State Street") pursuant to guidelines approved by Management. Effective February 7, 2005, the Fund changed the collateral investment vehicle from the Old Fund to the Neuberger Berman Securities Lending Quality Fund, LLC ("Quality Fund"), a fund managed by Lehman Brothers Asset Management LLC, an affiliate of Management, as approved by the Board. Income earned on the securities loaned, if any, is reflected in the Statement of Operations under the caption "Income from securities loaned-affiliated issuers." At December 31, 2005, the Fund had no securities out on loan. 10 REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements with institutions that Management 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. 12 <Page> 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, 2005, such excess expenses amounted to $12,100. 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, 2005, there was no reimbursement to Management under this agreement. At December 31, 2005, contingent liabilities to Management under this agreement were as follows: <Table> <Caption> EXPIRING IN: 2006 2007 2008 TOTAL $ 57,506 $ 54,057 $ -- $ 111,563 </Table> Management and Neuberger, a member firm of the New York Stock Exchange and sub-adviser to the Fund, are 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 13 <Page> 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 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, 2005, the impact of this arrangement was a reduction of expenses of $3,440. The Fund has an expense offset arrangement in connection with its custodian contract. For the year ended December 31, 2005, the impact of this arrangement was a reduction of expenses of $582. NOTE C--SECURITIES TRANSACTIONS: During the year ended December 31, 2005, there were purchase and sale transactions (excluding short-term securities) of $34,354,017 and $7,206,926, respectively. During the year ended December 31, 2005, brokerage commissions on securities transactions amounted to $48,427, of which Neuberger received $1,948, Lehman received $9,437, and other brokers received $37,042. NOTE D--FUND SHARE TRANSACTIONS: Share activity for the years ended December 31, 2005 and December 31, 2004 was as follows: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, 2005 2004 SHARES SOLD 2,432,866 1,089,692 SHARES ISSUED ON REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS 6,630 SHARES REDEEMED (607,213) (163,804) --------- --------- TOTAL 1,832,283 925,888 --------- --------- </Table> NOTE E--LINE OF CREDIT: At December 31, 2005, the Fund was a participant in a single committed, unsecured $150,000,000 line of credit with a consortium of banks organized by State Street, to be used only for temporary or emergency purposes. Other investment companies managed by Management also participate in this line of credit on the same terms. Interest is charged on borrowings under this agreement at the overnight Federal Funds Rate plus 0.50% per annum. A facility fee of 0.09% 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. Because several investment companies participate, there is no assurance that an individual fund will have access to all or any part of the $150,000,000 at any particular time. There were no loans outstanding pursuant to this line of credit at December 31, 2005. During the year ended December 31, 2005, the Fund did not utilize this line of credit. 14 <Page> NOTE F--INVESTMENTS IN AFFILIATES*: <Table> <Caption> INCOME FROM INVESTMENTS BALANCE OF BALANCE OF IN SHARES GROSS SHARES AFFILIATED HELD GROSS SALES HELD VALUE ISSUERS DECEMBER 31, PURCHASES AND DECEMBER 31, DECEMBER 31, INCLUDED IN NAME OF ISSUER 2004 AND ADDITIONS REDUCTIONS 2005 2005 TOTAL INCOME Neuberger Berman Securities Lending Quality Fund, LLC** 631,300 30,799,346 31,430,646 -- $ -- $ 1,792 </Table> * Affiliated issuers, as defined in the 1940 Act. ** Prior to February 7, 2005, the Old Fund, an investment vehicle established by the Fund's custodian, was used to invest cash the Fund received as collateral for securities loans.

Because all shares of the Old Fund and Quality Fund were and are held by funds in the related investment company complex, the Old Fund and Quality Fund may have been and may be considered affiliates of the Fund. 15 <Page> FINANCIAL HIGHLIGHTS SOCIALLY RESPONSIVE PORTFOLIO The following table includes selected data for a share outstanding throughout each year and other performance information derived from the Financial Statements. <Table> <Caption> YEAR ENDED DECEMBER 31, ------------------------------------------------------- 2005 2004 2003 2002 2001 NET ASSET VALUE, BEGINNING OF YEAR $ 13.99 $ 12.35 $ 9.19 $ 10.78 $ 11.17 ------- ------- ------- ------- ------- INCOME FROM INVESTMENT OPERATIONS: NET INVESTMENT INCOME (LOSS)+++ .08 (.00) (.01) (.01) -- NET GAINS OR LOSSES ON SECURITIES (BOTH REALIZED AND UNREALIZED) .88 1.64 3.17 (1.58) (.39) ------- ------- ------- ------- ------- TOTAL FROM INVESTMENT OPERATIONS .96 1.64 3.16 (1.59) (.39) ------- ------- ------- ------- ------- LESS DISTRIBUTIONS FROM: NET CAPITAL GAINS (.04) -- -- -- -- ------- ------- ------- ------- ------- NET ASSET VALUE, END OF YEAR $ 14.91 $ 13.99 $ 12.35 $ 9.19 $ 10.78 ------- ------- ------- ------- ------- TOTAL RETURN++ +6.86% +13.28% +34.39% -14.75% -3.58% RATIOS/SUPPLEMENTAL DATA NET ASSETS, END OF YEAR (IN MILLIONS) $ 50.5 $ 21.7 $ 7.7 $ 5.0 $ 3.6 RATIO OF GROSS EXPENSES TO AVERAGE NET ASSETS# 1.30% 1.31% 1.35% 1.52% 1.59% RATIO OF NET EXPENSES TO AVERAGE NET ASSETS~ 1.29% 1.29% 1.34% 1.51% 1.53% RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS .53% (.03)% (.08)% (.07)% .04% PORTFOLIO TURNOVER RATE 24% 21% 45% 38% 277% </Table> See Notes to Financial Highlights 16 <Page> NOTES TO FINANCIAL HIGHLIGHTS SOCIALLY RESPONSIVE PORTFOLIO ++ 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.

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. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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, a series of Neuberger Berman Advisers Management Trust, at December 31, 2005, 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 the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 18 <Page> TRUSTEES AND OFFICERS The following tables set forth information concerning the trustees and officers of the Trust.

In evaluating the Agreements, the Board, including the Independent Fund Trustees, reviewed materials furnished by Neuberger Berman Management Inc. ("Management") and Neuberger Berman, LLC ("Neuberger") in response to questions submitted by counsel to the Independent Fund Trustees, and met with senior representatives of Management and Neuberger regarding their personnel and operations. The Independent Fund Trustees were advised by counsel that is experienced in Investment Company Act of 1940 matters and that is independent of Management and Neuberger. The Independent Fund Trustees received a memorandum from independent counsel discussing the legal standards for their consideration of the proposed continuance of the Agreements. They met with such counsel separately from representatives of Management to discuss the annual contract review. The annual contract review extends over two regular meetings of the Board to ensure that Management and Neuberger have time to respond to any questions the Independent Fund Trustees may have on their initial review of the report and that the Independent Fund Trustees have time to consider those responses. In addition, during this process, the Board held a separate meeting devoted to reviewing and discussing Fund performance. The Board considered the following factors, among others, in connection with its approval of the continuance of the Agreements: (1) the nature, extent, and quality of the services to be provided by Management and Neuberger; (2) the performance of the Fund compared to relevant market indices and a peer group of investment companies; (3) the costs of the services to be provided and profits historically realized by Management and its affiliates from the relationship with the Fund; (4) the extent to which economies of scale might be realized as the Fund grows; and (5) whether fee levels reflect those potential economies of scale for the benefit of investors in the Fund. In their deliberations, the Board members did not identify any particular information that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board evaluated the terms of the Agreements and whether the Agreements were in the best interests of the Fund and its shareholders. The Board considered, with respect to the Fund, the nature, extent and quality of the services provided under the Agreements and the overall fairness of the Agreements to the Fund. The Board requested and evaluated a report from Management and Neuberger that addressed specific factors designed to inform the Board's consideration of these and other issues. The Board also retained an independent consultant to provide additional data. With respect to the nature, extent and quality of the services provided, the Board considered the performance of the Fund and the degree of risk undertaken by the portfolio managers. The Board considered the experience and staffing of portfolio management and the investment research personnel of Management and Neuberger dedicated to performing services for the Fund. The Board noted that Management also provides certain administrative services, including fund accounting and compliance oversight. The Board also considered Management's and Neuberger's policies and practices regarding brokerage and allocation of portfolio transactions for the Fund. The Board considered the quality of brokerage execution provided by Management and its affiliates. The Board's Portfolio Transactions and Pricing Committee from time to time reviews the quality of the brokerage services that Neuberger and Lehman provide, and has reviewed studies by independent firms engaged to review and evaluate the quality of brokerage execution received by the Fund. In addition, the Board noted the positive compliance history of Management and Neuberger, as each firm has been free of significant compliance problems. With respect to the performance of the Fund, the Board considered the short-, intermediate- and long-term performance of the Fund relative to its benchmark and a peer group of investment companies dedicated to insurance products pursuing broadly similar strategies. The Board also considered long-term performance in relation to the degree of risk undertaken by the portfolio managers. With respect to the overall fairness of the Agreements, the Board considered the fee structure of the Agreements as compared to a peer group of funds dedicated to insurance products and any fall-out benefits likely to accrue to Management or Neuberger or their affiliates. The Board also considered the profitability of Management and its affiliates from their association with the Fund. 28 <Page> The Board received a detailed report from an independent consultant that compares the Fund's management fee and overall expense ratio to a peer group of funds dedicated to insurance products. The Board considered the range and average of the management fees and expense ratios of the peer group. With regard to the sub-advisory fee paid to Neuberger, the Board noted that this fee is reflective of an "at cost" basis and there is no profit to Neuberger with regard to these fees. The Board considered the Fund's overall expenses in relation to the overall expenses of the peer group median. In addition, the Board considered the contractual and voluntary limits on Fund expenses undertaken by Management for the Fund. The Board noted that Management incurred a loss on the Fund on an after-tax basis. The Board considered whether there were other funds that were sub-advised by Management or its affiliates or separate accounts managed by Management with similar investment objectives, policies and strategies as the Fund. The Board noted that there were no comparable sub-advised funds or separate accounts. The Board also evaluated any actual or anticipated economies of scale in relation to the services Management provides to the Fund. The Board considered the Fund's fee structure which provides for a reduction of payments resulting from the use of breakpoints and whether those breakpoints are set at appropriate asset levels. In concluding that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund, the Board reviewed specific data as to Management's profit or loss on the Fund for a recent period and the trend in profit or loss over recent years. The Board also carefully examined Management's cost allocation methodology and had an independent expert review the methodology. It also reviewed an analysis from an independent data service on investment management profitability margins. The Board also reviewed whether Management and Neuberger used brokers to execute Fund transactions that provide research and other services to Management and Neuberger, and the types of benefits potentially derived by the Fund and by other clients of Management and Neuberger from such services. The Board recognized that Management should be entitled to earn a reasonable level of profits for services it provides to the Fund and, based on its review, concluded it was satisfied that Management's level of profitability from its relationship with the Fund was not excessive. CONCLUSIONS In approving the Agreements, the Board concluded that the terms of each Agreement are fair and reasonable and that approval of the Agreements is in the best interest of the Fund and its shareholders. In reaching this determination, the Board considered that Management and Neuberger could be expected to provide a high level of service to the Fund; the performance of the Fund was satisfactory over time; that the Fund's fee structure appeared to the Board to be reasonable given the quality of services expected to be provided; and that the benefits accruing to Management and its affiliates by virtue of their relationship to the Fund were reasonable in comparison with the costs of providing the investment advisory services and the benefits accruing to the Fund. 29 ITEM 2.
