DOW CHAIRMAN - -------------------------------------------------------------------------------- Q: WHAT WERE THE OVERALL MARKET CONDITIONS OF THE REPORTING PERIOD? A: The Federal Reserve Board (the Fed) continued its measured pace of interest rate hikes, raising the fed funds rate in 0.25% increments in January, March, May, and June, bringing the rate to 5.25% at the end of the six month period. The June 29, 2006, interest rate hike marked the seventeenth quarter-point increase since June 2004. Longer-term rates rose also, with the yield on the 30-year Treasury bond reaching its highest level in nearly two years on higher energy costs and fears of increasing inflation. Despite a weak bond market, high yield and convertible securities managed to advance. These securities tend to be less sensitive to interest rate movements than more traditional fixed income investments, and thus were less affected by the bond market's decline. Convertible and high yield securities do tend to be more sensitive to economic activity, and these securities benefited from the continued economic strength and low credit default rates of the past two quarters. Q: HOW DID THE FUND PERFORM OVER THE SIX MONTH PERIOD ENDED JUNE 30, 2006? A: The Fund returned 2.2%, reflecting performance at the net asset value (NAV) of Class A shares with all distributions reinvested, compared with its benchmark, the Lehman Brothers U.S. Aggregate Bond Index,1 which returned -0.7% over the same period. AVERAGE ANNUAL TOTAL 1 <Page> - -------------------------------------------------------------------------------- RETURNS, WHICH REFLECT PERFORMANCE AT THE MAXIMUM 4.75% SALES CHARGE APPLICABLE TO CLASS A SHARE INVESTMENTS AND INCLUDE THE REINVESTMENT OF ALL DISTRIBUTIONS ARE: 1 YEAR: -0.75%, 5 YEARS: 5.32%, AND 10 YEARS: 5.74%. PERFORMANCE DATA QUOTED REFLECT PAST PERFORMANCE AND ARE NO GUARANTEE OF FUTURE RESULTS. CURRENT PERFORMANCE MAY BE HIGHER OR LOWER THAN THE PERFORMANCE QUOTED. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT SHARES, ON ANY GIVEN DAY OR WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. YOU CAN OBTAIN PERFORMANCE DATA CURRENT TO THE MOST RECENT MONTH END BY CALLING LORD ABBETT AT 800-821-5129 OR REFERRING TO OUR WEBSITE AT WWW.LORDABBETT.COM. Q: WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE? A: The greatest contributor to performance in the period, relative to the Fund's benchmark, was the portfolio's holdings of high yield securities. Convertible securities also added to performance, as did the portfolio's equity holdings. Both high yield bonds and convertible securities outperformed investment-grade bonds in the period. Within the investment-grade sector, the portfolio's holdings in mortgage-backed securities also helped relative performance, as mortgages outperformed both investment-grade corporate bonds and U.S. Treasury bonds. Detracting from performance relative to the Fund's benchmark in the high yield bond sector was the portfolio's underweight position in CCC rated securities and preference for higher rated securities. Triple Cs outperformed both BB and B rated securities during the period. In the convertible securities sector, drug manufacturer Celgene Corp. made the greatest individual contribution to performance, followed by Schlumberger Ltd., an oil field services company; Hanover Compressor, a firm that rents and repairs compressors for the oil and gas industries; and Apogent Technologies, a manufacturer of laboratory products for the clinical and industrial markets. Detracting from performance in the convertible securities sector were Teva Pharmaceutical Finance, the finance arm of the Israeli-based pharmaceutical firm; CV Therapeutics, a developer of molecular cardiology products; Openwave Sytems, a software and services provider to the telecommunications business; and The Interpublic Group of Companies, an advertising and marketing services firm. Contributing to performance in the high yield bond sector were auto manufacturer General Motors Corp.; Ineos Group Holdings, a diversified chemical company; and global communications and information services company Level 3 Communications and its financing arm, Level 3 Financing. Detracting from performance in the high yield bond sector were: Dole Food Co., a major food processor firm; Chesapeake Energy Corp., an 2 <Page> independent explorer and production company focusing on natural gas; Ainsworth Lumber Co., a producer of lumber, plywood and flooring; and hospital operator HCA Inc. In the investment-grade sector, as mentioned earlier, the portfolio's holdings in the mortgage-backed securities market contributed to performance relative to the benchmark. The greatest single contributor to performance in the investment-grade sector was Airgate PCS Inc., a wireless telecommunications company. Also adding to performance were Corning Inc., a provider of optical fiber, cable, and communications network equipment; Alamosa Holdings, a wireless communications company; and Cummins, Inc., a manufacturer of large diesel engines. Detracting from performance were gaming company Harrah's; utility company PG&E Corp.; Freescale Semiconductor, a manufacturer of microchips; and Wells Fargo & Co., the nation's fifth largest bank. The Fund also participates in the equity market. Contributing to performance in the equity sector were Archer Daniels Midland, a processor of oilseeds, corn, and wheat; Qwest Communications International, a provider of long-distance telephone, as well as broadband data, voice, and video services; BEA Systems, a provider of application server software; and Mentor Graphics Corp., a provider of electronic design automation software and systems. Detracting from performance in the equity sector were Comverse Technology, a manufacturer of communication systems and software; Amgen Inc., a biotech drug manufacturer; Sun Microsystems, a maker of UNIX-based servers used to power corporate computer networks and Websites; and utility company TECO Energy, Inc. 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. NOTE: Class A shares purchased subject to a 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.

The index covers the investment-grade, fixed-rate bond market, with index components for government and corporate securities, mortgage pass-through securities and asset-backed securities. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment. IMPORTANT PERFORMANCE AND OTHER INFORMATION The views of the Fund's management and the portfolio holdings described in this report are as of June 30, 2006; these views and portfolio holdings may have changed subsequent to this date and they do not guarantee the future performance of the markets or the Fund. Information provided in this report should not be considered a recommendation to purchase or sell securities. A NOTE ABOUT RISK: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with the Fund, please see the Fund's prospectus. PERFORMANCE: BECAUSE OF ONGOING MARKET VOLATILITY, FUND PERFORMANCE MAY BE SUBJECT TO SUBSTANTIAL FLUCTUATION. Except where noted, comparative Fund performance does not account for the deduction of sales charges and would be different if sales charges were included. The Fund offers additional classes of shares with distinct pricing options. For a full description of the differences in pricing alternatives, please see the Fund's prospectus. 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 (January 1, 2006 through June 30, 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 1/1/06 - 6/30/06" 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 5.0% 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 5.0% hypothetical example with the 5.0% 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> EXPENSES BEGINNING ENDING PAID DURING ACCOUNT ACCOUNT PERIOD+ VALUE VALUE ----------- --------- --------- 1/1/06 - 1/1/06 6/30/06 6/30/06 --------- --------- ----------- CLASS A Actual $1,000.00 $1,021.80 $4.96 Hypothetical (5% Return Before Expenses) $1,000.00 $1,019.88 $4.96 CLASS B Actual $1,000.00 $1,019.60 $8.21 Hypothetical (5% Return Before Expenses) $1,000.00 $1,016.64 $8.20 CLASS C Actual $1,000.00 $1,019.70 $8.21 Hypothetical (5% Return Before Expenses) $1,000.00 $1,016.64 $8.20 CLASS P Actual $1,000.00 $1,022.20 $5.47 Hypothetical (5% Return Before Expenses) $1,000.00 $1,019.37 $5.46 CLASS Y Actual $1,000.00 $1,023.70 $3.21 Hypothetical (5% Return Before Expenses) $1,000.00 $1,021.61 $3.21 </Table> + For each class of the Fund, expenses are equal to the annualized expense ratio for such class (0.99% for Class A, 1.64% for Classes B and C, 1.09% for Class P and 0.64% for Class Y) multiplied by the average account value over the period, multiplied by 181/365 (to reflect one-half year period). =============================================================================== PORTFOLIO HOLDINGS PRESENTED BY SECTOR JUNE 30, 2006 <Table> <Caption> SECTOR* %** Agency 7.34% Banking 1.20% Basic Industry 7.42% Brokerage 0.42% Capital Goods 5.55% Communications 0.14% Consumer Cyclical 5.92% Consumer Non-Cyclical 6.83% Energy 8.79% Finance & Investment 1.21% Government Guaranteed 2.31% Insurance 0.37% Media 9.23% Mortgage Backed 1.43% Services Cyclical 11.69% Services Non-Cyclical 4.92% Technology & Electronics 4.79% Telecommunications 5.47% Utility 5.31% Short-Term Investments 9.66% Total 100.00% </Table> * A sector may comprise several industries. ** Represents percent of total investments. 6 <Page> SCHEDULE OF INVESTMENTS (UNAUDITED) JUNE 30, 2006 <Table> <Caption> SHARES U.S. $ INVESTMENTS (000) VALUE - -------------------------------------------------------------------------------- LONG-TERM INVESTMENTS 96.90% COMMON STOCKS 5.35% AEROSPACE/DEFENSE 0.11% EDO CORP. 350 $ 8,519,000 ----------- AGRICULTURE 0.14% ARCHER DANIELS MIDLAND CO. 250 10,320,000 ----------- BANKING 0.23% WACHOVIA CORP. 325 17,576,000 ----------- BEVERAGE 0.32% COCA-COLA CO.

SEE NOTES TO FINANCIAL STATEMENTS. 33 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 1. ORGANIZATION Lord Abbett Bond-Debenture Fund, Inc. (the "Fund") is registered under the Investment Company Act of 1940 (the "Act") as a diversified open-end management investment company. The Fund was incorporated under Maryland law on January 23, 1976. The Fund's investment objective is to seek high current income and the opportunity for capital appreciation to produce a high total return. 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. Fixed income securities are valued at the mean between the bid and asked prices on the basis of prices supplied by independent pricing services, which reflect broker/dealer supplied valuations and electronic data processing techniques. Exchange-traded options and futures contracts are valued at the last sale price in the market where they are principally traded. If no sale has occurred, the mean between the most recently quoted bid and asked prices is used. 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 Directors. 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. 34 <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 generally 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) FOREIGN TRANSACTIONS-The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund's records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted to reflect current exchange rates. The resultant exchange gains and losses are included as Net Realized Gain (Loss) on Investments and Foreign Currency Related Transactions on the Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities. (g) FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS-The Fund may enter into forward foreign currency exchange contracts in order to reduce its exposure to changes in foreign currency exchange rates on its foreign portfolio holdings and to lock in the U.S. dollar cost of firm purchase and sale commitments for securities denominated in foreign currencies. A forward foreign currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. The contracts are valued daily at forward exchange rates and any unrealized gain (loss) is included in Net Change in Unrealized Appreciation (Depreciation) on Investments and Translation of Assets and Liabilities Denominated in Foreign Currencies on the Statement of Operations. The gain (loss) arising from the difference between the U.S. dollars cost of the original contract and the value of the foreign currency in U.S. dollars upon closing of such contracts is included in Net Realized Gain (Loss) on Investments and Foreign Currency Related Transactions on the Statement of Operations. As of June 30, 2006, there were no open forward foreign currency exchange contracts outstanding. (h) SECURITIES LENDING-The Fund may lend its securities to member banks of the Federal Reserve System and to registered broker/dealers approved by the Fund. The loans are collateralized at all times by cash and/or U.S. Government securities in an amount at least equal to 102% of the market value of domestic securities loaned (105% in the case of foreign securities loaned) as determined at the close of business on the preceding business day. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. Lending portfolio securities could result in a loss or delay in recovering the Fund's securities if the borrower defaults. As of June 30, 2006, the value of securities loaned was $678,677,044. These loans are collateralized by cash of $689,508,616, which is invested in a restricted money market account. State Street Bank & Trust Company ("SSB") received fees of $258,559 for the six months ended June 30, 2006, which are netted against Securities Lending Income on the Statement of Operations. (i) 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 35 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) 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. (j) STRUCTURED SECURITIES-The Fund may invest in structured securities. Structured securities are a type of derivative security whose value is determined by reference to changes in the value of specific underlying securities, currencies, interest rates, commodities, indices, credit default swaps, or other indicators (the "Reference"), or to relative changes in two or more References. The interest rate or principal amount payable upon maturity or redemption may be increased (decreased) depending upon changes in the applicable Reference or certain specified events. Structured securities may be positively or negatively indexed with the result that the appreciation of the Reference may produce an increase (decrease) in the interest rate or the value of the security at maturity. (k) WHEN-ISSUED OR FORWARD TRANSACTIONS-The Fund may purchase portfolio securities on a when-issued or forward basis. When-issued, forward transactions or to-be-announced ("TBA") transactions involve a commitment by the Fund to purchase securities, with payment and delivery ("settlement") to take place in the future, in order to secure what is considered to be an advantageous price or yield at the time of entering into the transaction. During the period between purchase and settlement, the value of the securities will fluctuate and assets consisting of cash and/or marketable securities (normally short-term U.S. Government or U.S. Government sponsored enterprises securities) marked to market daily in an amount sufficient to make payment at settlement will be segregated at a Fund's custodian in order to pay for the commitment. At the time the Fund makes the commitment to purchase a security on a when-issued basis, it will record the transaction and reflect the liability for the purchase and value of the security in determining its net asset value. The Fund, generally, has the ability to close out a purchase obligation on or before the settlement date rather than take delivery of the security. Under no circumstances will settlement for such securities take place more than 120 days after the purchase date. 3. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES MANAGEMENT FEES The Fund 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 the following annual rates: ..50% of the first $500 million of average daily net assets; ..45% of the next $9.5 billion; ..40% over $10 billion. 36 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) 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. The Fund, along with certain other funds managed by Lord Abbett (the "Underlying Funds"), have entered into a Servicing Arrangement with Balanced Strategy Fund of Lord Abbett Investment Trust (the "Fund of Funds"), pursuant to which each Underlying Fund pays a portion of the expenses (excluding management fees and distribution and service fees) of the Fund of Funds in proportion to the average daily value of Underlying Fund shares owned by the Fund of Funds. Amounts paid pursuant to the Servicing Arrangement are included in Subsidy Expense on the Statement of Operations. 12b-1 DISTRIBUTION PLAN 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%(1) .25% .25% .20% Distribution .10%(2) .75% .75% .25% </Table> (1) Annual service fee on shares sold prior to June 1, 1990 is .15% of the average daily net asset value. (2) The amount of CDSC collected by the Fund for the six months ended June 30, 2006 was $10,925. Class Y does not have a distribution plan. COMMISSIONS The 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 June 30, 2006: <Table> <Caption> DISTRIBUTOR DEALERS' COMMISSIONS CONCESSIONS - ------------------------- $836,413 $4,328,364 </Table> Distributor received CDSCs of $2,938 and $30,997 for Class A and Class C shares, respectively, for the six months ended June 30, 2006. One Director and certain of the Fund'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 monthly. 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. 37 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) The tax character of distributions paid during the six months ended June 30, 2006 and the fiscal year ended December 31, 2005 are as follows: <Table> <Caption> SIX MONTHS ENDED 6/30/2006 YEAR ENDED (UNAUDITED) 12/31/2005 - ------------------------------------------------------------ Distributions paid from: Ordinary income $255,638,807 $541,345,754 - ------------------------------------------------------------ Total distributions paid $255,638,807 $541,345,754 ============================================================ </Table> As of December 31, 2005, the capital loss carryforwards, along with the related expiration dates are as follows: <Table> <Caption> 2009 2010 TOTAL - ------------------------------------------ $219,436,086 $303,185,812 $522,621,898 </Table> As of June 30, 2006, the aggregate unrealized security gains and losses based on cost for U.S. Federal income tax purposes are as follows: <Table> Tax cost $8,285,556,008 - ------------------------------------------------ Gross unrealized gain 243,694,215 Gross unrealized loss (331,093,301) - ------------------------------------------------ Net unrealized security loss $ (87,399,086) ================================================ </Table> The difference between book-basis and tax-basis unrealized gains (losses) is attributable primarily to the tax treatment of amortization and other temporary tax adjustments. 5. PORTFOLIO SECURITIES TRANSACTIONS Purchases and sales of investment securities (excluding short-term investments) for the six months ended June 30, 2006 are as follows: <Table> <Caption> U.S. NON-U.S. U.S. NON-U.S. GOVERNMENT GOVERNMENT GOVERNMENT GOVERNMENT PURCHASES* PURCHASES SALES* SALES - ------------------------------------------------------------- $346,341,794 $1,013,392,076 $259,694,906 $1,389,077,283 </Table> * Includes U.S. Government sponsored enterprises securities 6. DIRECTORS' REMUNERATION The Fund's officers and the one Director who are associated with Lord Abbett do not receive any compensation from the Fund for serving in such capacities. Outside Directors 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 Directors under which outside Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors' 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 Directors' Fees on the Statement of Operations and in Directors' 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. 38 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) 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, have 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. Any borrowings under this Facility will bear interest at current market rates as defined in the agreement. The fee for this Facility is an annual rate of .08%. As of June 30, 2006, there were no loans outstanding pursuant to this Facility nor was the Facility utilized at any time during the six months ended June 30, 2006. 9. CUSTODIAN AND ACCOUNTING AGENT SSB is the Fund's custodian and accounting agent. SSB performs custodial, 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 investing in debt securities. The value of an investment will change as interest rates fluctuate and in response to market movements. When interest rates rise, the prices of debt securities are likely to decline; when rates fall, such prices tend to rise. Longer-term securities are usually more sensitive to interest rate changes. There is also the risk that an issuer of a debt security will fail to make timely payments of principal or interest to the Fund, a risk that is greater with high yield securities (sometimes called "lower-rated debt securities" or "junk bonds") in which the Fund may invest. Some issuers, particularly of high yield securities, may default as to principal and/or interest payments after the Fund purchases its securities. A default, or concerns in the market about an increase in risk of default, may result in losses to the Fund. High yield bonds are subject to greater price fluctuations, as well as additional risks. The mortgage-related securities in which the Fund may invest may be particularly sensitive to changes in prevailing interest rates. When interest rates are declining, the value of these securities with prepayment features may not increase as much as other fixed income securities. Early principal repayment may deprive the Fund of income payments above current market rates. The prepayment rate also will affect the price and volatility of a mortgage-related security. Some of these securities may be those of such Government sponsored enterprises as Federal Home Loan Mortgage Corporation and Federal National Mortgage Association. Such securities are guaranteed with respect to the timely payment of interest and principal by the particular Government sponsored enterprise involved, not by the U.S. Government. The Fund may invest up to 5% of its net assets in structured securities. The Fund typically may use these securities as a substitute for taking a position in the underlying asset and/or as part of a strategy designed to reduce exposure to other risk, such as interest rate or currency risk. Structured securities may present additional risks that are different from those associated with a direct investment in fixed-income or equity securities; they may be volatile, less liquid and 39 <Page> NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED) more difficult to price accurately and subject to additional credit risks. Changes in the value of structured securities may not correlate perfectly with the underlying asset, rate or index. The Fund that invests in structured securities could lose more than the principal amount invested. The Fund may invest up to 20% of its net assets in equity securities which may subject it to the general risks and considerations associated with investing in equity securities. 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. The Fund may invest up to 20% of its net assets in foreign securities which may present market liquidity, currency, political, information, and other risks. These factors can affect the Fund's performance. 11.

RECENT ACCOUNTING PRONOUNCEMENT In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Fund will adopt FIN 48 during 2007 and the impact to the Fund's financial statements, if any, is currently being assessed. 41 <Page> HOUSEHOLDING The Fund 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." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 800-821-5129 or send a written request with your name, the name of your fund or funds, and your account number or numbers to Lord Abbett Family of Funds, P.O. Box 219336, Kansas City, MO 64121. PROXY VOTING POLICIES, PROCEDURES AND RECORD A description of the policies and procedures that Lord Abbett uses to vote proxies related to the Fund's portfolio securities, and information on how Lord Abbett voted the Fund's proxies during the twelve month period ended June 30, 2006, are available without charge, upon request, (i) by calling 888-522-2388; (ii) on Lord Abbett's website at www.LordAbbett.com; and (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov. SHAREHOLDER REPORTS AND QUARTERLY PORTFOLIO DISCLOSURE The Fund is required to file its complete schedule of portfolio holdings with the SEC for its first and third fiscal quarters on Form N-Q.

At the June 22, 2006 meetings of the Nominating and Governance Committees (the "Committee") of the Boards of each of the Lord Abbett Funds, the Committee adopted policies and procedures for the nomination of independent directors/trustees ("Procedures"). The Procedures provide criteria for the nomination of independent directors/trustees, as well as a process for identifying and evaluating candidates. With respect to shareholder recommendations, it is the Committee's policy to consider director/trustee nominations recommended by shareholders using the same criteria the Committee uses in considering potential director/trustee nominations from other sources. The Committee believes that directors/trustees must represent all shareholders and not just a limited set of shareholders. A copy of the Procedures may be found at www.LordAbbett.com. <Page> ITEM 11: CONTROLS AND PROCEDURES.
