On this and the following pages, we discuss the major factors that influenced performance. Thank you for investing in Lord Abbett mutual funds. We value the trust that you place in us and look forward to serving your investment needs in the years to come. BEST REGARDS, /s/ Robert S. Dow ROBERT S. DOW CHAIRMAN - -------------------------------------------------------------------------------- Q: WHAT WERE THE OVERALL MARKET CONDITIONS OF THE SIX-MONTH PERIOD ENDED JANUARY 31, 2006? A: During the period, a few major trends dominated the equity markets. Perhaps most influential was the building strength of equities, especially during the latter half of the period, as the U.S. economy proved resilient. Across the indexes tracked by Standard & Poor's, equities with a value bias outperformed growth stocks. However, strip away the dominance of large-capitalization stocks in market-weighted aggregate indexes - and the picture changes. In style-box fashion, mid-capitalization growth stocks led small growth equities, which in turn outperformed large value stocks. Although large value equities outperformed their growth-oriented peers during the period, large-cap growth gained substantial momentum in the broad rally experienced in November 2005 and January 2006. In the broad S&P Super Composite 1500(R) Index,(1) the top performing sectors during the period included energy, materials, and financials, while the underperforming sectors were consumer discretionary, telecommunications, and consumer staples. Q: HOW DID THE FUND PERFORM OVER THE SIX-MONTH PERIOD ENDED JANUARY 31, 2006? A: The fund returned 10.3 percent, reflecting performance at the net asset value (NAV) of Class A shares, with all distributions reinvested, compared with its benchmark, the Russell 2000(R) Index,(2) which returned 8.5 percent over the same period. STANDARDIZED AVERAGE ANNUAL TOTAL RETURNS, WHICH REFLECT PERFORMANCE AT THE MAXIMUM 5.75 PERCENT SALES CHARGE APPLICABLE TO CLASS A SHARE INVESTMENTS AND INCLUDE THE REINVESTMENT OF ALL DISTRIBUTIONS, AS OF JANUARY 31, 2006, ARE: 1 YEAR: 13.47 PERCENT AND SINCE INCEPTION (JUNE 26, 2001): 15.35 PERCENT. Class A shares purchased subject to a 1 <Page> - -------------------------------------------------------------------------------- front-end sales charge have no contingent deferred sales charge (CDSC). However, certain purchases of Class A shares made without a front-end sales charge may be subject to a CDSC. Please see section "Your Investment-Purchases" in the prospectus for more information on redemptions that may be subject to a CDSC.

Q: WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE OVER THE SIX-MONTH PERIOD ENDED JANUARY 31, 2006? CONTRIBUTING TO FUND PERFORMANCE A: The materials and processing sector was the strongest contributor to performance, relative to the fund's benchmark, followed by the financial services sector and the fund's underweight position in the utilities sector. Strong performing materials and processing holdings included Hughes Supply, Inc., a wholesale distributor of construction, repair, and maintenance-related products, and Commercial Metals Co., a provider of steel and metal products and related materials. Other materials and processing companies, Cleveland-Cliffs Inc., an iron ore pellets producer, and Watsco, Inc., a distributor of air conditioning, heating, and refrigeration equipment, related parts and supplies, also performed well during the period. Although the financial services sector ranked second in terms of sector contribution to performance, relative to the fund's benchmark, none of the fund's financial services holdings were among the top 10 contributors to performance. However, three of the fund's top 10 largest holdings were financial services companies. In addition, the fund's lack of exposure to the utilities sector, relative to its benchmark, proved to be a positive factor. Select Comfort Corp., a consumer discretionary holding that provides a line of airbed mattresses with adjustable firmness, as well as foundations and accessories, was a solid contributor to performance and the fourth largest holding for the period. Additional holdings 2 <Page> - -------------------------------------------------------------------------------- that performed well included Pride International, Inc., a company listed in the other energy sector. Pride International provides contract drilling and related services on land and offshore. It was the fund's largest holding and the strongest contributor to performance. Two healthcare stocks were also among the top 10 contributors to performance: LCA-Vision Inc., which develops and operates stand-alone laser vision correction centers, and Par Pharmaceutical Cos. Inc., which manufactures and distributes generic drugs. In addition, producer durables company, Actuant Corp., a maker of a broad range of industrial products and systems, and technology holding Websense, Inc., a provider of employee Internet management solutions, each helped fund performance. Websense was the fund's tenth largest holding for the period. DETRACTING FROM FUND PERFORMANCE The worst performing sector for the fund, relative to the fund's benchmark, during the period was technology. Stratasys, Inc., a maker of rapid prototyping systems, and Hutchinson Technology Inc., a supplier of suspension assemblies for hard disk drives, took away from fund performance. The consumer discretionary and the producer durables sectors detracted equally from performance relative to the fund's benchmark. Tuesday Morning Corp., a closeout retailer of upscale home furnishings, gifts, and related items, was the weakest performing holding for the period. Other consumer discretionary holdings that hurt fund performance included Entravision Communications Corp., a diversified media company; Regent Communications, Inc., a radio broadcasting company; SM&A, a provider of competition management services; and Dave & Buster's, Inc., an operator of restaurant entertainment complexes. Producer durables holding, The Ryland Group, Inc., a homebuilder and mortgage-related finance firm, was the fund's second largest holding for the period, and a detractor from fund performance. Other stocks that disappointed were healthcare company Kensey Nash Corp. and Massey Energy Co., categorized in the other energy sector. Kensey makes a line of absorbable medical devices. Massey produces, processes, and sells bituminous, low sulphur coal of steam and metallurgical grades through its processing and shipping centers. Massey was the fund's fifth largest holding. THE FUND'S PORTFOLIO IS ACTIVELY MANAGED AND, THEREFORE, ITS HOLDINGS AND WEIGHTINGS OF A PARTICULAR ISSUER OR PARTICULAR SECTOR AS A PERCENTAGE OF PORTFOLIO ASSETS ARE SUBJECT TO CHANGE. SECTORS MAY INCLUDE MANY INDUSTRIES. 3 <Page> - -------------------------------------------------------------------------------- A PROSPECTUS CONTAINS IMPORTANT INFORMATION ABOUT A FUND, INCLUDING ITS INVESTMENT OBJECTIVES, RISKS, CHARGES, AND ONGOING EXPENSES, WHICH AN INVESTOR SHOULD CAREFULLY CONSIDER BEFORE INVESTING.

MUTUAL FUNDS ARE NOT INSURED BY THE FDIC, ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF, OR GUARANTEED BY, BANKS, AND ARE SUBJECT TO INVESTMENT RISKS, INCLUDING POSSIBLE LOSS OF PRINCIPAL AMOUNT INVESTED. 4 <Page> - -------------------------------------------------------------------------------- EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges on purchase payments (these charges vary among the share classes); and (2) ongoing costs, including management fees; distribution and service (12b-1) fees (these charges vary among the share classes); and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (August 1, 2005 through January 31, 2006). ACTUAL EXPENSES For each class of the Fund, the first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that 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 line under the heading entitled "Expenses Paid During the Period 8/1/05 - 1/31/06" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES For each class of the Fund, the second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. 5 <Page> - -------------------------------------------------------------------------------- Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES ACCOUNT ACCOUNT PAID DURING VALUE VALUE PERIOD+ ----- ----- ------- 8/1/05 - 8/1/05 1/31/06 1/31/06 ------ ------- -------- CLASS A Actual $ 1,000.00 $ 1,103.40 $ 7.21 Hypothetical (5% Return Before Expenses) $ 1,000.00 $ 1,018.35 $ 6.92 CLASS B Actual $ 1,000.00 $ 1,099.60 $ 10.59 Hypothetical (5% Return Before Expenses) $ 1,000.00 $ 1,015.12 $ 10.16 CLASS C Actual $ 1,000.00 $ 1,099.70 $ 10.59 Hypothetical (5% Return Before Expenses) $ 1,000.00 $ 1,015.12 $ 10.16 CLASS P Actual $ 1,000.00 $ 1,103.00 $ 7.69 Hypothetical (5% Return Before Expenses) $ 1,000.00 $ 1,017.90 $ 7.38 CLASS Y Actual $ 1,000.00 $ 1,105.40 $ 5.31 Hypothetical (5% Return Before Expenses) $ 1,000.00 $ 1,020.16 $ 5.09 </Table> + For each class of the Fund, expenses are equal to the annualized expense ratio for such class (1.36% for Class A, 2.00% for Classes B and C, 1.45% for Class P, and 1.00% for Class Y) multiplied by the average account value over the period, multiplied by 184/365 (to reflect one-half year period). - -------------------------------------------------------------------------------- PORTFOLIO HOLDINGS PRESENTED BY SECTOR JANUARY 31, 2006 <Table> <Caption> SECTOR* %** Auto & Transportation 2.48% Consumer Discretionary 17.80% Consumer Staples 1.80% Financial Services 13.68% Healthcare 14.33% Materials & Processing 13.27% Other Energy 9.01% Producer Durables 12.45% Technology 8.10% Short-Term Investment 7.08% Total 100.00% </Table> * A sector may comprise several industries. ** Represents percent of total investments. 6 <Page> SCHEDULE OF INVESTMENTS (UNAUDITED) JANUARY 31, 2006 <Table> <Caption> VALUE INVESTMENTS SHARES (000) - ------------------------------------------------------------------------------ COMMON STOCKS 91.78% AIR TRANSPORTATION 0.28% Republic Airways Holdings Inc.* 286,801 $ 4,253 ------------ AUTO COMPONENTS 1.25% Wabash National Corp. 882,850 18,831 ------------ BANKS: OUTSIDE NEW YORK CITY 1.40% Hanmi Financial Corp. 353,358 6,710 Investors Financial Services Corp. 134,300 6,304 PrivateBancorp, Inc. 213,700 8,080 ------------ TOTAL 21,094 ------------ BIOTECHNOLOGY RESEARCH & PRODUCTION 1.21% Digene Corp.* 305,629 10,147 Kensey Nash Corp.* 331,304 8,087 ------------ TOTAL 18,234 ------------ BUILDING: MATERIALS 2.02% Hughes Supply, Inc. 659,700 30,412 ------------ BUILDING: ROOFING & WALLBOARD 1.85% Beacon Roofing Supply, Inc.* 561,811 18,658 ElkCorp 263,300 9,260 ------------ TOTAL 27,918 ------------ CASINOS & GAMBLING 0.37% Alliance Gaming Corp.* 370,500 5,635 ------------ COAL 3.68% Arch Coal, Inc. 131,100 11,369 Massey Energy Co. 1,067,100 44,018 ------------ TOTAL 55,387 ------------ COMMUNICATIONS & MEDIA 1.37% Entravision Communications Corp.* 2,912,800 20,681 ------------ COMMUNICATIONS TECHNOLOGY 0.82% WebEx Communications, Inc.* 508,537 $ 12,347 ------------ COMPUTER SERVICES, SOFTWARE & SYSTEMS 4.10% CACI Int'l.

ORGANIZATION Lord Abbett Blend Trust (the "Trust") is registered under the Investment Company Act of 1940 (the "Act") as an open-end management company, organized as a Delaware Business Trust on May 1, 2001. The Trust has one series, Lord Abbett Small-Cap Blend Fund (the "Fund"). The Securities and Exchange Commission declared the registration of the Fund and its shares effective on June 26, 2001 and each class of shares became available to the public on July 2, 2001. The Fund is diversified under the Act. The Fund's investment objective is to seek long-term growth of capital by investing primarily in stocks of small companies. The Fund offers five classes of shares: Classes A, B, C, P and Y, each with different expenses and dividends. A front-end sales charge is normally added to the Net Asset Value ("NAV") for Class A shares. There is no front-end sales charge in the case of the Classes B, C, P and Y shares, although there may be a contingent deferred sales charge ("CDSC") as follows: certain redemptions of Class A shares made within 24 months (12 months if shares were purchased on or after November 1, 2004) following certain purchases made without a sales charge; Class B shares redeemed before the sixth anniversary of purchase; and Class C shares redeemed before the first anniversary of purchase. Class B shares will convert to Class A shares on the eighth anniversary of the original purchase of Class B shares. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. 2. SIGNIFICANT ACCOUNTING POLICIES (a) INVESTMENT VALUATION-Securities traded on any recognized U.S. or non-U.S. exchange or on NASDAQ, Inc. are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices. Securities for which market quotations are not readily available are valued at fair value as determined by management and approved in good faith by the Board of Trustees. Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates current market value. (b) SECURITY TRANSACTIONS-Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method. Realized and unrealized gains (losses) are allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day. (c) INVESTMENT INCOME-Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis. Discounts are accreted and premiums are amortized using the effective interest method. Investment income is allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day. 18 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) (d) FEDERAL TAXES-It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no Federal income tax provision is required. (e) EXPENSES-Expenses, excluding class specific expenses, are allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day. Classes A, B, C, and P shares bear all expenses and fees relating to their respective 12b-1 Distribution Plans. (f) REPURCHASE AGREEMENTS-The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which the Fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the value of those securities has declined, the Fund may incur a loss upon disposition of the securities. 3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES MANAGEMENT FEE The Trust has a management agreement with Lord, Abbett & Co. LLC ("Lord Abbett") pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, pays the remuneration of officers, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund's investment portfolio. The management fee is based on the following annual rates: .75% of the first $1 billion of average daily net assets; .70% over $1 billion. Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement at an annual rate of .04% of the Fund's average daily net assets. 12b-1 DISTRIBUTION PLANS The Fund has adopted a distribution plan with respect to one or more classes of shares pursuant to Rule 12b-1 of the Act, which provides for the payment of ongoing distribution and service fees to Lord Abbett Distributor LLC ("Distributor"), an affiliate of Lord Abbett. The fees are accrued daily at annual rates based upon average daily net assets as follows: <Table> <Caption> FEE CLASS A CLASS B CLASS C CLASS P - --------------------------------------------------------------------------------- Service .25% .25% .25% .20% Distribution .10%(1)(2) .75% .75% .25% </Table> (1) Until October 1, 2004, the Fund paid a one-time distribution fee of up to 1.00% on certain qualifying purchases of Class A shares. Effective October 1, 2004, the Distributor commenced payment of such one-time distribution fee. The unamortized balance of the prepaid distribution fees as of January 31, 2006 was $19,851. This amount will continue to be amortized by the Fund, generally over a two-year period. (2) The amount of CDSC collected during the six months ended January 31, 2006 was $872. 19 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) Class Y does not have a distribution plan. COMMISSIONS Distributor received the following commissions on sales of shares of the Fund, after concessions were paid to authorized dealers, for the six months ended January 31, 2006: <Table> <Caption> DISTRIBUTOR DEALERS' COMMISSIONS CONCESSIONS - ----------------------------- $ 584,426 $ 3,342,616 </Table> Distributor received CDSCs of $1,262 and $15,076 for Class A and Class C shares, respectively, for the six months ended January 31, 2006. One Trustee and certain of the Trust's officers have an interest in Lord Abbett. 4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARD Dividends from net investment income, if any, are declared and paid at least annually. Taxable net realized gains from investment transactions, reduced by capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with Federal income tax regulations which may differ from accounting principles generally accepted in the United States of America. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions, which exceed earnings and profits for tax purposes, are reported as a tax return of capital. The tax character of distributions paid during the six months ended January 31, 2006 and the fiscal year ended July 31, 2005 are as follows: <Table> <Caption> SIX MONTHS ENDED 1/31/2006 YEAR ENDED (UNAUDITED) 7/31/2005 - ---------------------------------------------------------------------- Distributions paid from: Ordinary income $ 16,605,582 $ 17,492,584 Net long-term capital gains 15,526,679 16,910,374 - ---------------------------------------------------------------------- Total distributions paid $ 32,132,261 $ 34,402,958 ====================================================================== </Table> As of January 31, 2006, the Fund's aggregate unrealized security gains (losses) based on cost for U.S. Federal income tax purposes are as follows: <Table> Tax cost $ 1,289,785,780 - ------------------------------------------------ Gross unrealized gain 214,547,547 Gross unrealized loss (16,985,352) - ------------------------------------------------ Net unrealized security gain $ 197,562,195 ================================================ </Table> The difference between book-basis and tax-basis unrealized gains (losses) is attributable to wash sales. 20 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) 5. PORTFOLIO SECURITIES TRANSACTIONS Purchases and sales of investment securities (excluding short-term investments) for the six months ended January 31, 2006 are as follows: <Table> <Caption> PURCHASES SALES - ---------------------------------- $ 637,306,999 $ 210,868,433 </Table> There were no purchases or sales of U.S. Government securities for the six months ended January 31, 2006. 6. TRUSTEES' REMUNERATION The Trust's officers and the one Trustee who are associated with Lord Abbett do not receive any compensation from the Trust for serving in such capacities. Outside Trustees' fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity based plan available to all outside Trustees under which outside Trustees must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Trustees' fees. The deferred amounts are treated as though equivalent dollar amounts have been invested proportionately in the funds. Such amounts and earnings accrued thereon are included in Trustees' Fees on the Statement of Operations and in Trustees' Fees Payable on the Statement of Assets and Liabilities and are not deductible for U.S. Federal income tax purposes until such amounts are paid. 7. EXPENSE REDUCTIONS The Fund has entered into arrangements with its transfer agent and custodian whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund's expenses. 8. LINE OF CREDIT The Fund, along with certain other funds managed by Lord Abbett, has available a $250,000,000 unsecured revolving credit facility ("Facility") from a consortium of banks, to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. Effective December 9, 2005, the amount available to the funds under the Facility was increased from $200,000,000 to 250,000,000. Any borrowings under this Facility will bear interest at current market rates as defined in the agreement. The fee for this Facility is at an annual rate of .08%. At January 31, 2006, there were no loans outstanding pursuant to this Facility nor was the Facility utilized at any time during the six months ended January 31, 2006. 9. CUSTODIAN AND ACCOUNTING AGENT State Street Bank & Trust Company ("SSB") is the Fund's custodian and accounting agent.

INVESTMENT RISKS The Fund is subject to the general risks and considerations associated with equity investing as well as the particular risks associated with growth and value stocks. The value of an investment will fluctuate in response to movements in the stock market in general and to the changing prospects of individual companies in which the Fund invests. Different types of stocks shift in and out of favor depending on market and economic conditions. Growth stocks tend to be more volatile than other stocks. The market may fail to recognize the intrinsic value of particular value stocks for a long time. In addition, if the Fund's assessment of a company's potential for growth or market conditions is wrong, it could suffer losses or produce poor performance relative to other funds, even in a rising market. The Fund invests primarily in small company stocks, which tend to be more volatile and can be less liquid than large company stocks. Small companies may also have more limited product lines, markets or financial resources, and typically experience a higher risk of failure than large companies. These factors can affect the Fund's performance. 12.

SUBSEQUENT EVENT As of the close of business on January 31, 2006, Class A, B, C, P, and Y shares of the Fund are not available for purchase by new investors other than through certain retirement and benefit plans, and financial intermediaries that provide recordkeeping or advisory services and have entered into special arrangements with the Fund or the Distributor. In addition, Directors/Trustees of the Lord Abbett Family of Funds, partners and employees of Lord Abbett, and the family members of such persons may purchase shares of the Fund. Investors should note, however, that the Fund reserves the right to refuse any order that might disrupt the efficient management of the Fund. 23 <Page> APPROVAL OF ADVISORY CONTRACTS At meetings on December 7 and 8, 2005, the Board, including all Trustees who are not interested persons, considered whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett. In addition to the materials the Board had reviewed throughout the course of the year, the Board received materials relating to the management agreement before the meeting and had the opportunity to ask questions and request further information in connection with its consideration. The Board also took into account its familiarity with Lord Abbett gained through its previous meetings and discussions, and the examination of the portfolio management team conducted by members of the Contract Committee during the year. The materials received by the Board included, but were not limited to, (1) information provided by Lipper Analytical Services, Inc. regarding the investment performance of the Fund compared to the investment performance of a group of funds with substantially similar investment objectives (the "performance universe") and to the investment performance of an appropriate securities index (if such an index existed), for various time periods each ending September 30, 2005, (2) information on the effective management fee rates and expense ratios for funds with similar objectives and similar size (the "peer group"), (3) sales and redemption information for the Fund, (4) information regarding Lord Abbett's financial condition, (5) an analysis of the relative profitability of the management agreement to Lord Abbett, (6) information regarding the distribution arrangements of the Fund, (7) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund. INVESTMENT MANAGEMENT SERVICES GENERALLY. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett's commitment to compliance with all relevant legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest resulting from being engaged in other lines of business. The Board noted that Lord Abbett did not use brokerage commissions to purchase third-party research. The Board also considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. INVESTMENT PERFORMANCE AND COMPLIANCE. The Board reviewed the Fund's investment performance as well as the performance of the performance universe of funds, both in terms of total return and in terms of other statistical measures. The Board observed that the Fund's performance of the Class A shares of the Fund was in the first quintile of its performance universe for the nine-month and three-year periods and in the second quintile in the one-year period. The Board also observed that the performance was above that of the Lipper Small-Cap Core Index for each period. LORD ABBETT'S PERSONNEL AND METHODS. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, they considered the size, experience, and turnover rates of Lord Abbett's investment management staff, Lord Abbett's investment methodology and philosophy, and Lord Abbett's approach to recruiting, training, and retaining investment management personnel. The Board determined that Lord Abbett had the expertise and resources to manage the Fund effectively. 24 <Page> NATURE AND QUALITY OF OTHER SERVICES. The Board considered the nature, quality, costs, and extent of administrative and other services performed by Lord Abbett and Lord Abbett Distributor and the nature and extent of Lord Abbett supervision of third party service providers, including the Fund's transfer agent and custodian. EXPENSES. The Board considered the expense ratio of the Fund and the expense ratios of peer groups. It also considered the amount and nature of the fees paid by shareholders. The Board observed that the contractual and actual management and administrative services fees were approximately the same as the median of the peer group. The Board also observed that the total expense ratio of Class A was approximately nine basis points above the median of the peer group, the total expense ratios of Classes B and C were approximately five basis points below the median of the peer group, the total expense ratio of Class P was approximately thirteen basis points above the median of the peer group, and the total expense ratio of Class Y was approximately seven basis points above the median of the peer group. PROFITABILITY. The Board considered the level of Lord Abbett's profits in managing the Fund, including a review of Lord Abbett's methodology for allocating its costs to its management of the Fund. The Board concluded that the allocation methodology had a reasonable basis and was appropriate. It considered the profits realized by Lord Abbett in connection with the operation of the Fund and whether the amount of profit was fair for the management of the Fund. The Board also considered the profits realized from other businesses of Lord Abbett, which may benefit from or be related to the Fund's business. The Board considered Lord Abbett's profit margins in comparison with available industry data, both accounting for and ignoring marketing and distribution expenses, and how those profit margins could affect Lord Abbett's ability to recruit and retain investment personnel. The Board recognized that Lord Abbett's profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. The Board noted that Lord Abbett's profitability had increased, in part due to an increase in assets under management, but concluded that Lord Abbett's profitability overall and with respect to the Fund was not excessive. ECONOMIES OF SCALE. The Board considered whether there had been any economies of scale in managing the Fund, whether the Fund had appropriately benefited from any such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing advisory fee schedule adequately addressed any economies of scale in managing the Fund. OTHER BENEFITS TO LORD ABBETT. The Board considered the character and amount of fees paid by the Fund and the Fund's shareholders to Lord Abbett and Lord Abbett Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett's investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that Lord Abbett Distributor receives 12b-1 fees from the Fund as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees from the Fund, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Fund, but that that business also benefits the Fund. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. 25 <Page> ALTERNATIVE ARRANGEMENTS. The Board considered whether, instead of approving continuation of the management agreement, employing one or more alternative arrangements might be in the best interests of the Fund, such as continuing to employ Lord Abbett, but on different terms. In considering whether to approve the continuation of the management agreement, the Board did not identify any single factor as paramount or controlling. This summary does not discuss in detail all matters considered. After considering all of the relevant factors, the Board unanimously found that continuation of the existing management agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the management agreement. 26 <Page> HOUSEHOLDING The Trust has adopted a policy that allows it to send only one copy of the Fund's Prospectus, proxy material, annual report and semiannual report to certain shareholders residing at the same "household."
