1.	ORGANIZATION

Lord Abbett Bond-Debenture Fund, Inc. (the “Fund”) is registered under the Investment Company Act of 1940, as amended (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.


2 .	SIGNIFICANT ACCOUNTING POLICIES

(a)	Investment Valuation- Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.

	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 reflect their fair value as of the close of regular trading on the New York Stock Exchange LLC. The 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 the independent pricing services’ own electronic data processing techniques. Forward foreign currency exchange contracts are valued using daily forward exchange rates. Floating rate loans are valued at the average of bid and ask quotations obtained from dealers in loans on the basis of prices supplied by independent pricing services. 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 prices are not readily available are valued at fair value as determined by the Pricing Committee and approved by the Board. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use observable inputs such as related or comparable assets or liabilities, recent transactions, market multiples, book values, yield curves, broker quotes, observable trading activity, option adjusted spread models and other relevant information to determine fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing of any related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.

	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair 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 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.

	The Fund uses foreign currency exchange contracts to facilitate transactions in foreign-denominated securities. Losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts’ terms.

Notes to Schedule of Investments (unaudited)(continued)


(d)	Forward Foreign Currency Exchange Contracts -The 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 or gain or reduce exposure to foreign currency for investment purposes. 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.

(e)	Futures Contracts -The Fund may purchase and sell futures contracts to enhance returns, to attempt to hedge some of its investment risk, or as a substitute position for holding the underlying asset on which the instrument is based. 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 made or received by a Fund called “variation margin” are made on a daily basis as the market price of the futures contract fluctuates. The Fund 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.

(f)	When-Issued or Forward Transactions -The Fund may purchase portfolio securities on a when-issued or forward basis. When-issued or forward 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 fair 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 the 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 fair 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.

(g)	Repurchase Agreements- The 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. 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 fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.

(h)	Floating Rate Loans -The 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 prime rate offered by a designated U.S. bank or London InterBank Offered Rate (“LIBOR”).

	The loans in which the Fund invests may be subject to some restrictions on resale. For example, the Fund may be contractually obligated to receive approval from the Agent and/or Borrower prior to the sale of these investments. The Fund generally has no right to enforce compliance with the terms of the loan agreement with the Borrower. As a result, the 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 enter 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. As of March 28, 2013, the Fund had the following unfunded loan commitments:


Security Name	Par Value

Constellation Brands, Inc. Bridge Term Loan	$	23,000,000
Diamond Foods, Inc. Revolver		1,743,570
Milacron LLC - Bridge Term Loan		25,000,000

Total	$	49,743,570

(i)

Fair Value Measurements -Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used 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 - unadjusted 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 the Fund’s own assumptions in determining the fair value of investments).

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.


	The following is a summary of the inputs used as of March 28, 2013 in valuing the Fund’s investments carried at fair value:

	*	See Schedule of Investments for fair values in each industry and identification of foreign issuers and/or geography.
	**	Floating Rate Loans categorized as Level 3 are valued based on a single quotation obtained from a dealer. The Fund does not have access to unobservable inputs and therefore cannot disclose such inputs in the valuation.
	⁽¹⁾	Tribune Co. was categorized as Level 2 on December 31, 2012 due to the use of an observable dealer quotation. This security was listed on the NASDAQ on January 4, 2013. Therefore, as of March 28, 2013, this security was categorized as Level 1 due to the use of an unadjusted quoted market closing price in an active market. Accordingly, $4,017,921 was transferred from Level 2 to Level 1 during the period ended March 28, 2013.
	⁽²⁾	Convertible Preferred Stocks categorized as Level 2 investments include AMG Capital Trust I, Bunge Ltd. and Cooper-Standard Holdings, Inc. PIK
	⁽³⁾	Corporate Bonds categorized as Level 3 investments include General Motors Co., Hellas II (Luxembourg) and Washington Mutual Bank.
	⁽⁴⁾	Whiting Petroleum Corp. was categorized as Level 2 on December 31, 2012 resulting from limited market trading activity. As of March 28, 2013, this security was categorized as Level 1 due to the use of an unadjusted quoted market closing price in an active market. Accordingly, $396,384 was transferred from Level 2 to Level 1 during the period ended March 28, 2013.
	⁽⁵⁾	Preferred Stocks categorized as Level 2 investments include U.S. Bancorp.
	⁽⁶⁾	Warrants categorized as Level 3 investments include ION Media Networks, Inc.
	⁽⁷⁾	Unfunded Commitments categorized as Level 3 investments include Diamond Foods, Inc. Revolver.

	The following is a reconciliation of investments with unobservable inputs (Level 3) that were used in determining fair value:

(j)	Disclosures about Derivative Instruments and Hedging Activities -The Fund entered into forward foreign currency exchange contracts for the period ended March 28, 2013 (as described in Note 2(d)). A forward foreign currency exchange contract reduces the 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 Fund’s risk of loss from counterparty credit risk is the unrealized appreciation on foreign currency exchange contracts and deposits as collateral.

Notes to Schedule of Investments (unaudited)(concluded)


	The Fund entered into U.S. Treasury futures contracts for the period ended March 28, 2013 (as described in note 2(e)) to hedge against changes in interest rates. The Fund bears the risk of interest rates moving unexpectedly, in which case the Fund may not achieve the anticipated benefits of the futures contracts and realize a loss. There is minimal counterparty credit risk to the Fund since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees futures against default.

	As of March 28, 2013, the Fund had the following derivatives, grouped into appropriate risk categories that illustrate how and why the Fund uses derivative instruments:


Asset Derivatives	Interest Rate Contracts		Forward Foreign Currency Exchange Contracts		Fair Value

Forward Foreign Currency Exchange Contracts	$	—	$	1,039,930	$	1,039,930

Total	$	—	$	1,039,930	$	1,039,930

Liability Derivatives

Forward Foreign Currency Exchange Contracts	$	—	$	31,460	$	31,460
Futures Contracts		259,718		—		259,718

Total	$	259,718	$	31,460	$	291,178


3.	FEDERAL TAX INFORMATION

As of March 28, 2013, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:


Tax cost	$	8,128,471,908

Gross unrealized gain		653,536,729
Gross unrealized loss		(170,278,701	)

Net unrealized security gain	$	483,258,028

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