IO Interest Only.

PO Principal Only.

# Variable rate security. The interest rate represents the rate at August 31, 2009.

† Security was purchased pursuant to Rule 144A under the Securities Act of 1933 and, unless registered under the Act or exempted from registration, may only be resold to qualified institutional investors. Unless otherwise noted, 144A securities are deemed to be liquid.

(a) Foreign security/securities traded in U.S. dollars.

(b) Floating Rate Loans in which the Fund invests generally pay interest at rates that are periodically re-determined at a margin above the London Inter-Bank Offered Rate (“LIBOR”) or the prime rate offered by major U.S. banks.

(c) Illiquid security. The total market value of these securities at August 31, 2009 is $403,133, which represents 0.06% of the Fund’s net assets.

(d) IOettes. These securities represent the right to receive interest payments on an underlying pool of mortgages with similar features as those associated with IO securities. Unlike IO’s, however, a nominal amount of principal is assigned to an IOette. This amount is very small in relation to the interest flow that constitutes almost all of the IOette cash flow. The stated price and coupon are linked to that small principal amount and therefore appear unusually large.

(e) Amount is less than $1,000.

(f) Securities have been fully/partially segregated to cover margin requirements for open futures contracts as of August 31, 2009 (See Note 2(e)).

(g) Other assets in excess of liabilities include net unrealized appreciation (depreciation) on futures contracts and forward foreign currency exchange contracts, as follows:

Open Futures Contracts at August 31, 2009:

1. ORGANIZATION

Lord Abbett Investment Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company and was organized as a Delaware Statutory Trust on August 16, 1993. The Trust currently consists of the following eleven funds (separately, a “Fund” and collectively, the “Funds”): Lord Abbett Balanced Strategy Fund (“Balanced Strategy Fund”), Lord Abbett Convertible Fund (“Convertible Fund”), Lord Abbett Core Fixed Income Fund (“Core Fixed Income Fund”), Lord Abbett Diversified Equity Strategy Fund (“Diversified Equity Strategy Fund”), Lord Abbett Diversified Income Strategy Fund (“Diversified Income Strategy Fund”), Lord Abbett Floating Rate Fund (“Floating Rate Fund”), Lord Abbett Growth & Income Strategy Fund (“Growth & Income Strategy Fund”), Lord Abbett High Yield Fund (“High Yield Fund”), Lord Abbett Income Fund (“Income Fund”), Lord Abbett Short Duration Income Fund (“Short Duration Income Fund”) and Lord Abbett Total Return Fund (“Total Return Fund”).

Balanced Strategy Fund’s investment objective is to seek current income and capital growth.

Each of Diversified Income Strategy Fund’s and Floating Rate Fund’s investment objective is to seek a high level of current income. Growth & Income Strategy Fund’s investment objective is to seek long-term capital appreciation and growth of income. High Yield Fund’s investment objective is to seek high current income and the opportunity for capital appreciation to produce a high total return. Each of Income Fund’s and Short Duration Income Fund’s investment objective is to seek a high level of income consistent with preservation of capital. Each of Balanced Strategy Fund, Diversified Equity Strategy Fund, Diversified Income Strategy Fund and Growth & Income Strategy Fund invests in other mutual funds (“Underlying Funds”) managed by Lord, Abbett & Co. LLC (“Lord Abbett”).

2. SIGNIFICANT ACCOUNTING POLICIES

(a) Investment Valuation-Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange LLC (“NYSE”). Each Fund may rely on an independent fair valuation service in adjusting the valuations of foreign securities. 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. Loans are valued at the average of bid and ask quotations from dealers in loans on the basis of prices supplied by independent pricing services. 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. Investments in the Underlying Funds are valued at their net asset value (“NAV”) each business day at the close of regular trading on the NYSE, normally 4:00 p.m. Eastern time. 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).

(c) Foreign Transactions-The books and records of each Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in each Fund’s records at the rate prevailing when earned or recorded.

(d) Forward Foreign Currency Exchange Contracts-The Floating Rate Fund, High Yield Fund, Income Fund, Short Duration Income Fund and Total Return Fund may enter into forward foreign currency exchange contracts in order to reduce their exposure to changes in foreign currency exchange rates on their 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. Forward contracts may also be structured for cash settlement, rather than physical delivery. The contracts are valued daily at forward exchange rates. As of August 31, 2009, only Income Fund had open forward foreign currency exchange contracts.

Notes to Schedule of Investments (unaudited)(continued)

(e) Futures Contracts-Each Fund may purchase and sell futures contracts for bona fide hedging purposes including hedging against changes in interest rates and securities prices. At the time of entering into a futures transaction, an investor is required to deposit and maintain a specified amount of cash or eligible securities called “initial margin”. Subsequent payments called “variation margin” are made on a daily basis as the market price of the futures contract fluctuates. The Funds will record an unrealized gain (loss) based on the amount of variation margin. When a contract is closed, a realized gain (loss) is recorded equal to the difference between the opening and closing value of the contract. Generally, open futures contracts are marked to market for federal income tax purposes at fiscal year-end. As of August 31, 2009, Core Fixed Income Fund, Income Fund, and Short Duration Income Fund had open futures contracts.

(f) When-Issued or Forward Transactions-Each 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 a 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 enterprise securities) marked to market daily in an amount sufficient to make payment at settlement will be segregated at each Fund’s custodian in order to pay for the commitment. At the time each 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 NAV. Each 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.

(g) Repurchase Agreements-Each Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a 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. Each 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 these securities has declined, a Fund may incur a loss upon disposition of the securities.

(h) Mortgage Dollar Rolls-Each Fund may enter into mortgage dollar rolls in which a Fund sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date. During the roll period, each Fund loses the right to receive principal (including prepayments of principal) and interest paid on the securities sold.

(i) Time Deposits-Each Fund is authorized to temporarily invest a substantial amount of its assets in various short-term fixed income securities. Time deposits are non-negotiable deposits maintained at a banking institution for a specified period of time at a specified interest rate.

(j) Floating Rate Loans-The Floating Rate Fund, High Yield Fund, Income Fund, Short Duration Income Fund and Total Return Fund may invest in floating rate loans, which usually take the form of loan participations and assignments. Loan participations and assignments are agreements to make money available to U.S. or foreign corporations, partnerships or other business entities (the “Borrower”) in a specified amount, at a specified rate and within a specified time. A loan is typically originated, negotiated and structured by a U.S. or foreign bank, insurance company or other financial institution (the “Agent”) for a group of loan investors (“Loan Investors”). The Agent typically administers and enforces the loan on behalf of the other Loan Investors in the syndicate and may hold any collateral on behalf of the Loan Investors. Such loan participations and assignments are typically senior, secured and collateralized in nature. A Fund records an investment when the Borrower withdraws money and records interest as earned. These loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the London InterBank Offered Rate (“LIBOR”) or the prime rate offered by a designated U.S. bank.

The loans in which a Fund invests are generally readily marketable, but may be subject to some restrictions on resale. For example, a Fund may be contractually obligated to receive approval from the Agent and/or Borrower prior to the sale of these investments. A Fund generally has no right to enforce compliance with the terms of the loan agreement with the Borrower. As a result, a Fund assumes the credit risk of the Borrower, the selling participant and any other persons interpositioned between the Fund and the Borrower (“Intermediate Participants”). In the event that the Borrower, selling participant or Intermediate Participants become insolvent or enters into bankruptcy, the Fund may incur certain costs and delays in realizing payment or may suffer a loss of principal and/or interest.

Notes to Schedule of Investments (unaudited)(continued)

Unfunded commitments represent the remaining obligation of the Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. These unfunded amounts are recorded in memorandum accounts. As of August 31, 2009, the Floating Rate Fund had the following unfunded loan commitments:

Borrower	Unfunded Commitment		Unrealized Depreciation
Aleris International, Inc. Debtor in Possession Term Loan, 2/13/2010	$	125,222	$	(626	)
Cooper Standard Automotive, Inc. Debtor in Possession Term Loan A, 12/23/2011		139,147		(2,087	)
Cooper Standard Automotive, Inc. Debtor in Possession Term Loan B, 12/23/2011		54,113		(812	)
Total	$	318,482	$	(3,525	)

(k) Fair Value Measurements-In accordance with FASB Statement of Financial Accounting Standards No. SFAS 157, Fair Value Measurements (“SFAS 157”), fair value is defined as the price that each Fund would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. SFAS 157 established a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below:

• Level 1 - quoted prices in active markets for identical investments;

• Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and

• Level 3 - significant unobservable inputs (including each Fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

The following is a summary of the inputs used as of August 31, 2009 in valuing each Fund’s investments carried at value:

(l) Disclosures about Derivative Instruments and Hedging Activities-The Funds adopted FASB Statement of Financial Accounting Standards No. 161 “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”), effective December 1, 2008.

The Income Fund entered into forward foreign currency exchange contracts during the period ended August 31, 2009 (as described in note 2(d)). A forward foreign currency exchange contract reduces the Income Fund’s exposure to changes in the value of the currency it will deliver (or settle in cash) and increases its exposure to changes in the value of the currency it will receive (or settle in cash) for the duration of the contract. The Fund’s use of forward foreign currency exchange contracts involves the risk that Lord Abbett will not accurately predict currency movements, and the Fund’s returns could be reduced as a result. Forward foreign currency exchange contracts are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time. The Income Fund’s risk of loss from counterparty credit risk is the fair value of the foreign currency exchange contracts.

The Core Fixed Income Fund, Income Fund and Short Duration Income Fund entered into U.S. Treasury futures contracts during the period ended August 31, 2009 (as described in note 2(e)) to hedge against changes in interest rates. The Funds bear the risk of interest rates moving unexpectedly, in which case the Funds may not achieve the anticipated benefits of the futures contracts and realize a loss. There is minimal counterparty credit risk to the Funds since futures were exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees futures against default.

At August 31, 2009, the Core Fixed Income Fund, Income Fund and Short Duration Income Fund had the following derivatives, grouped into appropriate risk categories that illustrate how and why the Funds use derivative instruments:

	Core Fixed Income Fund
Asset Derivatives	Interest Rate Contracts		Fair Value

Gross unrealized loss		(1,455,351	)		(1,142,671	)
Net unrealized security gain	$	68,252,146		$	65,614,400

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to the tax treatment of certain securities, amortization, and wash sales.
