DOW CHAIRMAN - -------------------------------------------------------------------------------- Q: WHAT WERE THE OVERALL MARKET CONDITIONS OF THE REPORTING PERIOD? A: The U.S. economy continued to show signs of improvement during the third quarter of 2003, as domestic growth prospects and corporate profits improved. Further evidence of an economic recovery sparked the equity markets, adding to the market gains experienced in the second quarter. And while major indices advanced in the first part of the period, concerns over the viability of future growth grew as the summer ended. As the economy entered the final months of 2003, gross domestic product (GDP) numbers showed that the U.S. economy expanded by an impressive 8.2% annualized rate in the third quarter-well ahead of expectations and up from 3.3% annualized growth in the second quarter. In addition, productivity data, an important gauge for inflation, has remained strong and can be an important signal that interest rates may remain low in the near term. October's employment report showed an increase of 126,000 jobs, ahead of estimates, but more recent employment data has raised lingering questions about a possible jobless recovery. And while the unemployment rate dropped to 5.6% in January, further data has shown lower-than-expected job creation in December and January, disappointing some. Historically, however, it is not uncommon for employment statistics to improve more slowly than other economic indicators. GDP grew at a 4% annual pace in the fourth quarter, and although this was slightly below expectations, the data continued to reinforce the view of an improving economy. Furthermore, in the face of a continued rising equity market, debates over the direction of interest rates intensified towards the end of the period, as the Federal Reserve slightly changed its 1 <Page> stance that interest rates will remain low at 1% for a "considerable" amount of time. Q: HOW DID THE FUND PERFORM OVER THE SIX-MONTH PERIOD ENDED JANUARY 31, 2004? A: For the six-month period ended January 31, 2004, the Fund returned 24.9%, reflecting performance at the Net Asset Value (NAV) of Class A shares with all distributions reinvested, outperforming the Russell 2000(R) Index(1) which returned 22.7% over the same period. Standardized Average Annual Total Returns, which reflect performance at the maximum 5.75% sales charge applicable to Class A share investments and include the reinvestment of all distributions are: 1 year: 50.43% and Since Inception (06/26/01): 12.91%. Q: WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE? A: Stock selection within the healthcare sector was the largest benefit to the Fund's performance during the period. Specifically, the value of certain holdings in the biotechnology category increased, as investors rectified overly negative reactions to the company's prospects. Stock selection within the technology sector also added to the Fund's performance, as certain Fund holdings in the internet software category appreciated from strong top-line growth from increasing sales of next generation products. In addition, stock selection within the producer durables sector helped the Fund's relative return, as certain semiconductor stocks enjoyed strong operating results. Stock selection within the materials and processing sector was the largest detractor from relative performance during the period, as lower gross margins hurt select holdings within the chemical manufacturing category. Stock selection within the financial services sector also hurt the Fund's relative performance, as certain smaller insurance companies declined. In addition, stock selection within the energy sector detracted from Fund performance, as specific drilling companies declined. The Fund is actively managed and, as a result, asset allocations may change. Sectors may include many industries. (1) The Russell 2000(R) Index measures the performance of the 2,000 smallest companies in the Russell 3000(R) Index and represents approximately 8% of the total market capitalization of the Russell 3000(R) Index.

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 Class 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 following any 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 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 sales price or, if no sales 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 or 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. (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 15 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) 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. Class A, Class B, Class C and Class 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, U.S. Government securities or U.S. government sponsored enterprise securities having a value equal to, or in excess of, the value of the repurchase agreement. If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the value of these 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 average daily net assets at an annual rate of .75%. 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) .75% .75% .25% </Table> (1) In addition, the Fund pays a one-time distribution fee of up to 1% on certain qualifying purchases, which is generally amortized over a two-year period. Class Y does not have a distribution plan. 16 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) COMMISSIONS Distributor received the following commissions on sales of Class A shares of the Fund, after concessions were paid to authorized dealers, for the six months ended January 31, 2004: <Table> <Caption> DISTRIBUTOR DEALERS' COMMISSIONS CONCESSIONS - --------------------------------------------- $ 164,153 $ 906,224 </Table> 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 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 net investment income and net realized capital gains for tax purposes are reported as distributions of paid-in capital. The tax character of distributions paid during the six months ended January 31, 2004 and the fiscal year ended July 31, 2003 are as follows: <Table> <Caption> 1/31/2004 7/31/2003 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 1,319,721 $ -- Net long term capital gains 1,459,941 -- - -------------------------------------------------------------------------------- Total distributions paid $ 2,779,662 $ -- </Table> Capital losses incurred after October 31 ("Post-October losses") within the taxable year are deemed to arise on the first business day of the Fund's next taxable year. The Fund incurred and will elect to defer net capital losses of $427,819 during fiscal 2003. As of January 31, 2004, the Fund's aggregate unrealized security gains and losses based on cost for U.S. Federal income tax purposes are as follows: <Table> Tax cost $ 177,663,942 - ----------------------------------------------------------- Gross unrealized gain 34,783,962 Gross unrealized loss (2,336,825) - ----------------------------------------------------------- Net unrealized security gain $ 32,447,137 - ----------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized gains (losses) is primarily attributable to wash sales and other temporary tax adjustments. 17 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) 5. PORTFOLIO SECURITIES TRANSACTIONS Purchases and sales of investment securities (other than short-term investments) for the six months ended January 31, 2004 are as follows: <Table> <Caption> PURCHASES SALES - ------------------------------------------------ $ 115,143,527 $ 45,719,540 </Table> There were no purchases or sales of U.S. Government securities for the six months ended January 31, 2004. 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 $200,000,000 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. 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 .09%. At January 31, 2004, there were no loans outstanding pursuant to this Facility nor was the Facility utilized at any time during the six months then ended. 9. CUSTODIAN AND ACCOUNTING AGENT State Street Bank and Trust Company ("SSB") is the Fund's custodian and accounting agent. SSB performs custodian, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund's NAV. 10. 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 18 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONCLUDED) 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 Fund performance. 11. SUMMARY OF CAPITAL TRANSACTIONS The Trust has an unlimited number of authorized shares of beneficial interest. <Table> <Caption> SIX MONTHS ENDED JANUARY 31, 2004 YEAR ENDED (UNAUDITED) JULY 31, 2003 - ------------------------------------------------------------------------------------------------------- CLASS A SHARES SHARES AMOUNT SHARES AMOUNT - ------------------------------------------------------------------------------------------------------- Shares sold 3,654,969 $ 48,504,730 2,908,482 $ 28,100,893 Reinvestment of distributions 112,453 1,503,501 - - Shares reacquired (481,756) (6,484,226) (1,072,690) (10,036,648) - ------------------------------------------------------------------------------------------------------- Increase 3,285,666 $ 43,524,005 1,835,792 $ 18,064,245 - ------------------------------------------------------------------------------------------------------- CLASS B SHARES Shares sold 878,139 $ 11,401,450 817,977 $ 7,840,219 Reinvestment of distributions 27,304 360,957 - - Shares reacquired (140,723) (1,824,398) (274,061) (2,510,069) - ------------------------------------------------------------------------------------------------------- Increase 764,720 $ 9,938,009 543,916 $ 5,330,150 - ------------------------------------------------------------------------------------------------------- CLASS C SHARES Shares sold 1,398,935 $ 18,255,546 1,192,843 $ 11,424,129 Reinvestment of distributions 24,984 330,037 - - Shares reacquired (199,583) (2,588,725) (343,914) (3,203,563) - ------------------------------------------------------------------------------------------------------- Increase 1,224,336 $ 15,996,858 848,929 $ 8,220,566 - ------------------------------------------------------------------------------------------------------- CLASS P SHARES Reinvestment of distributions 1.78 $ 24 - $ - - ------------------------------------------------------------------------------------------------------- Increase 1.78 $ 24 - $ - - ------------------------------------------------------------------------------------------------------- CLASS Y SHARES Shares sold 360,292 $ 4,750,205 - $ - Reinvestment of distributions 5,449 73,075 - - - ------------------------------------------------------------------------------------------------------- Increase 365,741 $ 4,823,280 - $ - - ------------------------------------------------------------------------------------------------------- </Table> 19 <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 semi-annual report to certain shareholders residing at the same "household."
