The second part, the base prospectus, gives more general information, some of which may not apply to the notes and the debentures being offered. Generally, when we refer only to the prospectus, we are referring to both parts combined, and when we refer to the accompanying prospectus, we are referring to the base prospectus.
 
If the description of the notes and the debentures varies between the prospectus supplement and the accompanying prospectus, you should rely on the information in the prospectus supplement.

PROSPECTUS SUPPLEMENT SUMMARY
 
In this prospectus supplement, we refer to our subsidiaries Jefferies & Company, Inc. as Jefferies, Jefferies Execution Services, Inc. as Jefferies Execution, Jefferies Financial Products LLC as JFP, Jefferies International Limited as JIL and Jefferies High Yield Trading as JHYT.
 
The Company
 
Jefferies Group, Inc. and its subsidiaries (“we”, “us” or “our”) operate as a full-service global investment bank and institutional securities firm focused on growth and middle-market companies and their investors. We offer these companies capital raising, merger and acquisition, restructuring and other financial advisory services, and provide investors fundamental research and trade execution in equity, equity-linked, high yield and investment grade fixed income securities, as well as commodities and derivatives. We also provide asset management services and products to institutions and other investors.
 
Our principal operating subsidiary, Jefferies, was founded in 1962. Since 2000, we have pursued a strategy of continuing growth and diversification, whereby we have sought to increase our market share in each of the markets we serve and the products and services we offer, while at the same time expanding the breadth of our activities in an effort to mitigate the cyclical nature of the financial markets in which we operate. Our growth plan has been achieved through internal growth supported by the ongoing addition of experienced personnel in targeted areas, as well as the acquisition from time to time of complementary businesses. More recently, we have increased our global focus on serving companies and investors in Europe, the Middle East, Latin America and Asia.
 
Since April 2, 2007 we have been operating in three business segments, Capital Markets, Asset Management and High Yield Trading. Our Capital Markets reportable segment includes our traditional securities and investment banking activities. It is managed as a single operating segment that provides the research, sales, trading and investment banking effort for various fixed income, equity and advisory products and services. The Capital Markets segment comprises many divisions, with extensive interactions among each. In addition, we voluntarily choose to disclose our Asset Management segment, even though it is currently an “immaterial non-reportable” segment as defined by FASB 131, Disclosures about Segments of an Enterprise and Related Information. The Asset Management segment is primarily comprised of operating activities related to our non-integrated asset management businesses including Clear Lake CLO, Victoria Falls CLO, Summit Lake CLO, Diamond Lake CLO, Jefferies RTS Fund, Jefferies Paragon Fund and Jefferies Buckeye Fund. This segment does not include activity associated with our international asset management, which is managed by its own desk manager and is included as an integrated component of the Capital Markets reportable segment. On April 2, 2007 we consolidated our secondary market trading activities previously performed by our High Yield division and our High Yield Funds in Jefferies High Yield Trading LLC, or JHYT. Our High Yield Trading segment comprises secondary sales and trading of high yield securities and special situation securities, including bank debt, post-reorganization equity, public and private equity, equity derivatives, credit default swaps and other financial instruments. It makes markets in high yield and distressed securities and provides research coverage on these types of securities. We own 50% of the voting securities of the parent entity of JHYT and will consolidate JHYT for financial reporting purposes beginning with the second quarter of 2007.
 
As of December 31, 2006, we had 2,254 employees. We maintain offices throughout the world. Our principal executive offices are located at 520 Madison Avenue, 12th Floor, New York, New York 10022, and our telephone number there is (212) 284-2550.

(1) EBITDA is defined as earnings before interest expense, income taxes, depreciation and amortization expense, cumulative effect of change in accounting principle and minority interest. EBITDA is presented because we believe it is a useful indicator of funds available to service debt, although it is not a GAAP-based measure of liquidity or financial performance. We believe that EBITDA, while providing useful information, should not be considered in isolation or as an alternative to net income and cash flows as determined in accordance with GAAP. The following table presents a reconciliation of EBITDA, as presented above, to our net earnings, as shown on our consolidated statement of earnings, for the comparable period:

RISK FACTORS
 
In addition to the other information contained and incorporated by reference in this prospectus supplement and the accompanying prospectus, you should consider carefully the following factors before deciding to purchase the notes or the debentures.
 
Risks Associated With Our Business
 
The following factors describe some of the assumptions, risks, uncertainties and other factors that could adversely affect our business or that could otherwise result in changes that differ materially from our expectations. In addition to the factors mentioned in this report, we are also affected by changes in general economic and business conditions, acts of war, terrorism and natural disasters.
 
Changing conditions in financial markets and the economy could result in decreased revenues.
 
As an investment banking and securities firm, changes in the financial markets or economic conditions in the United States and elsewhere in the world could adversely affect our business in many ways, including the following:
 
  •  A market downturn could lead to a decline in the volume of transactions executed for customers and, therefore, to a decline in the revenues we receive from commissions and spreads.
 
  •  Unfavorable financial or economic conditions could likely reduce the number and size of transactions in which we provide underwriting, financial advisory and other services. Our investment banking revenues, in the form of financial advisory and underwriting or placement fees, are directly related to the number and size of the transactions in which we participate and could therefore be adversely affected by unfavorable financial or economic conditions.
 
  •  Adverse changes in the market could lead to a reduction in revenues from principal transactions and commissions.
 
  •  Adverse changes in the market could also lead to a reduction in revenues from asset management fees and investment income from managed funds and losses from managed funds. Continued increases in our asset management business, especially increases in the amount of our investments in managed funds, would make us more susceptible to adverse changes in the market.
 
Our principal trading and investments expose us to risk of loss.
 
A significant portion of our revenues is derived from trading in which we act as principal. Although a significant portion of our principal trading is “riskless principal” in nature, we may incur trading losses relating to the purchase, sale or short sale of high yield, international, convertible, and equity securities and futures and commodities for our own account and from other program or principal trading. Additionally, we have made substantial investments of our capital in debt securities, equity securities and commodities, including investments managed by us and investments managed by third parties. In any period, we may experience losses as a result of price declines, lack of trading volume, and illiquidity. From time to time, we may engage in a large block trade in a single security or maintain large position concentrations in a single security, securities of a single issuer, or securities of issuers engaged in a specific industry. In general, because our inventory is marked to market on a daily basis, any downward price movement in these securities could result in a reduction of our revenues and profits. In addition, we may engage in hedging transactions that if not successful, could result in losses.
 
Increased competition may adversely affect our revenues and profitability.
 
All aspects of our business are intensely competitive. We compete directly with numerous other brokers and dealers, investment banking firms and banks. In addition to competition from firms currently in the securities business, there has been increasing competition from others offering financial services, including automated trading and other services based on technological innovations. We believe that the principal factors


S-5


Table of Contents

affecting competition involve market focus, reputation, the abilities of professional personnel, the ability to execute the transaction, relative price of the service and products being offered and the quality of service. Increased competition or an adverse change in our competitive position could lead to a reduction of business and therefore a reduction of revenues and profits. Competition also extends to the hiring and retention of highly skilled employees. A competitor may be successful in hiring away an employee or group of employees, which may result in our losing business formerly serviced by such employee or employees. Competition can also raise our costs of hiring and retaining the key employees we need to effectively execute our business plan.
 
Operational risks may disrupt our business, result in regulatory action against us or limit our growth.
 
Our businesses are highly dependent on our ability to process, on a daily basis, a large number of transactions across numerous and diverse markets in many currencies, and the transactions we process have become increasingly complex. If any of our financial, accounting or other data processing systems do not operate properly or are disabled or if there are other shortcomings or failures in our internal processes, people or systems, we could suffer an impairment to our liquidity, financial loss, a disruption of our businesses, liability to clients, regulatory intervention or reputational damage. These systems may fail to operate properly or become disabled as a result of events that are wholly or partially beyond our control, including a disruption of electrical or communications services or our inability to occupy one or more of our buildings. The inability of our systems to accommodate an increasing volume of transactions could also constrain our ability to expand our businesses.
 
We also face the risk of operational failure or termination of any of the clearing agents, exchanges, clearing houses or other financial intermediaries we use to facilitate our securities transactions. Any such failure or termination could adversely affect our ability to effect transactions and manage our exposure to risk.
 
In addition, despite the contingency plans we have in place, our ability to conduct business may be adversely impacted by a disruption in the infrastructure that supports our businesses and the communities in which they are located. This may include a disruption involving electrical, communications, transportation or other services used by us or third parties with which we conduct business.
 
Our operations rely on the secure processing, storage and transmission of confidential and other information in our computer systems and networks. Although we take protective measures and endeavor to modify them as circumstances warrant, our computer systems, software and networks may be vulnerable to unauthorized access, computer viruses or other malicious code, and other events that could have a security impact. If one or more of such events occur, this potentially could jeopardize our or our clients’ or counterparties’ confidential and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our, our clients’, our counterparties’ or third parties’ operations. We may be required to expend significant additional resources to modify our protective measures or to investigate and remediate vulnerabilities or other exposures, and we may be subject to litigation and financial losses that are either not insured against or not fully covered through any insurance maintained by us.
 
Asset management revenue is subject to variability based on market and economic factors and the amount of assets under management.
 
Asset management revenue includes revenues we receive from management, administrative and performance fees from funds managed by us, revenues from asset management and performance fees we receive from third-party managed funds, and investment income from our investments in these funds. These revenues are dependent upon the amount of assets under management and the performance of the funds. If these funds do not perform as well as our asset management clients expect, our clients may withdraw their assets from these funds, which would reduce our revenues. Some of our revenues from management, administrative and performance fees are derived from our own investments in these funds. We experience significant fluctuations in our quarterly operating results due to the nature of our asset management business and therefore may fail to meet revenue expectations.

We face numerous risks and uncertainties as we expand our business.
 
We expect the growth of our business to come primarily from internal expansion and through acquisitions and strategic partnering. As we expand our business, there can be no assurance that our financial controls, the level and knowledge of our personnel, our operational abilities, our legal and compliance controls and our other corporate support systems will be adequate to manage our business and our growth. The ineffectiveness of any of these controls or systems could adversely affect our business and prospects. In addition, as we acquire new businesses, we face numerous risks and uncertainties integrating their controls and systems into ours, including financial controls, accounting and data processing systems, management controls and other operations. A failure to integrate these systems and controls, and even an inefficient integration of these systems and controls, could adversely affect our business and prospects.
 
Our business depends on our ability to maintain adequate levels of personnel.
 
We have made substantial increases in personnel. If a significant number of our key personnel leave, or if our business volume increases significantly over current volume, we could be compelled to hire additional personnel. At that time, there could be a shortage of qualified and, in some cases, licensed personnel whom we could hire. This could hinder our ability to expand or cause a backlog in our ability to conduct our business, including the handling of investment banking transactions and the processing of brokerage orders, all of which could harm our business, financial condition and operating results.
 
Extensive regulation of our business limits our activities, and, if we violate these regulations, we may be subject to significant penalties.
 
The securities industry in the United States is subject to extensive regulation under both federal and state laws. The SEC is the federal agency responsible for the administration of federal securities laws. In addition, self-regulatory organizations, principally NASD and the securities exchanges, are actively involved in the regulation of broker-dealers. Securities firms are also subject to regulation by regulatory bodies, state securities commissions and state attorneys general in those foreign jurisdictions and states in which they do business. Broker-dealers are subject to regulations which cover all aspects of the securities business, including sales methods, trade practices among broker-dealers, use and safekeeping of customers’ funds and securities, capital structure of securities firms, anti-money laundering, record-keeping and the conduct of directors, officers and employees. Broker-dealers that engage in commodities and futures transactions are also subject to regulation by the CFTC and the NFA. The SEC, self-regulatory organizations, state securities commissions, state attorneys general, the CFTC and the NFA may conduct administrative proceedings which can result in censure, fine, suspension, expulsion of a broker-dealer or its officers or employees, or revocation of broker-dealer licenses. Additional legislation, changes in rules or changes in the interpretation or enforcement of existing laws and rules, may directly affect our mode of operation and our profitability. Continued efforts by market regulators to increase transparency and reduce the transaction costs for investors, such as decimalization and NASD’s Trade Reporting and Compliance Engine, or TRACE, has affected and could continue to affect our trading revenue.
 
Our business is substantially dependent on our Chief Executive Officer.
 
Our future success depends to a significant degree on the skills, experience and efforts of Richard Handler, our Chief Executive Officer. We do not have an employment agreement with Mr. Handler which provides for his continued employment. The loss of his services could compromise our ability to effectively operate our business. In addition, in the event that Mr. Handler ceases to be the CEO of JHYT, its parent entity, and in certain circumstances, Jefferies Group, Inc., then investors in the parent entity of JHYT would have the right to cause us to redeem their interests. Although we have substantial key man life insurance covering Mr. Handler, the proceeds from the policy may not be sufficient to offset any loss in business.

Legal liability may harm our business.
 
Many aspects of our business involve substantial risks of liability, and in the normal course of business, we have been named as a defendant or co-defendant in lawsuits involving primarily claims for damages. The risks associated with potential legal liabilities often may be difficult to assess or quantify and their existence and magnitude often remain unknown for substantial periods of time. Private Client Services involves an aspect of the business that has historically had more risk of litigation than our institutional business. Additionally, the expansion of our business, including increases in the number and size of investment banking transactions and our expansion into new areas, imposes greater risks of liability. In addition, unauthorized or illegal acts of our employees could result in substantial liability to us. Substantial legal liability could have a material adverse financial effect or cause us significant reputational harm, which in turn could seriously harm our business and our prospects.
 
Our business is subject to significant credit risk.
 
In the normal course of our businesses, we are involved in the execution, settlement and financing of various customer and principal securities and commodities transactions. These activities are transacted on a cash, margin or delivery-versus-payment basis and are subject to the risk of counterparty or customer nonperformance. Although transactions are generally collateralized by the underlying security or other securities, we still face the risks associated with changes in the market value of the collateral through settlement date or during the time when margin is extended. We may also incur credit risk in our derivative transactions to the extent such transactions result in uncollateralized credit exposure to our counterparties. We seek to control the risk associated with these transactions by establishing and monitoring credit limits and by monitoring collateral and transaction levels daily. We may require counterparties to deposit additional collateral or return collateral pledged. In the case of aged securities failed to receive, we may, under industry regulations, purchase the underlying securities in the market and seek reimbursement for any losses from the counterparty.
 
Risks Associated with the Offering
 
In the absence of an active trading market for the notes and the debentures, you may not be able to resell them.
 
There is no existing market for the notes or the debentures, and we can offer no assurance as to the liquidity of any market that may develop, your ability to sell the notes or the debentures or the price at which you may be able to sell them. Future trading prices of the notes and the debentures will depend on many factors, including, among other things, prevailing interest rates, our operating results, our credit ratings and the market for similar securities. We do not intend to list the notes or the debentures on any securities exchange. Each of Merrill Lynch and Citigroup have advised us that it currently intends to make a market in the notes and the debentures. However, neither is obligated to do so and they may discontinue any market making at any time without notice.
 
We may redeem the notes and the debentures before maturity, and you may be unable to reinvest the proceeds at the same or a higher rate of return.
 
We may redeem all or a portion of the notes and the debentures at any time. The redemption price will equal the principal amount being redeemed, plus accrued interest to the redemption date, plus an amount described under “Description of the Notes and the Debentures.” If a redemption occurs, you may be unable to reinvest the money you receive in the redemption at a rate that is equal to or higher than the rate of return on the debentures.
 
The notes and the debentures will be effectively subordinated to liabilities of our subsidiaries.
 
The notes and the debentures will be the obligations of Jefferies Group, Inc. exclusively and will not be guaranteed by any of our subsidiaries or secured by any of our properties or assets. Jefferies Group, Inc. is a holding company. We conduct almost all of our operations through our subsidiaries and a significant portion


S-8


Table of Contents

of our consolidated assets are held by our subsidiaries. Accordingly, our cash flow and our ability to service debt, including the notes and the debentures, is in large part dependent upon the results of operations of our subsidiaries and upon the ability of our subsidiaries to provide us cash (whether in the form of dividends, loans or otherwise) to pay amounts due in respect of our obligations, to pay any amounts due on the notes and the debentures or to make any funds available to pay such amounts. In addition, dividends, loans and other distributions from our subsidiaries to us are subject to restrictions imposed by law, including minimum net capital requirements, are contingent upon results of operations of such subsidiaries and are subject to various business considerations.
 
The notes and the debentures will be effectively subordinated as a claim against the assets of our subsidiaries to all existing and future liabilities of those subsidiaries (including indebtedness, guarantees, customer and counterparty obligations, trade payables, lease obligations and letter of credit obligations). Therefore, our rights and the rights of our creditors, including the holders of the notes and the debentures, to participate in the assets of any subsidiary upon its liquidation or reorganization will be subject to the prior claims of its creditors, except to the extent that we or they may be a creditor with recognized claims against the subsidiary.
 
Changes in our credit ratings may affect the trading value of the notes and the debentures.
 
Our credit ratings are an assessment of our ability to pay our obligations. Consequently, real or anticipated changes in our credit ratings may affect the trading value of the notes and the debentures. A credit rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating organization. No person is obligated to maintain any rating on the notes or the debentures, and, accordingly, we cannot assure you that the ratings assigned to the notes or the debentures will not be lowered or withdrawn by the assigning rating organization at any time thereafter.

USE OF PROCEEDS
 
We estimate that the net proceeds from the issuance and sale of the notes and the debentures, after deducting the underwriting discount and expenses relating to the offering, will be approximately $          . We plan to use these proceeds to pay the holders of our $100 million aggregate principal amount of 7.50% Senior Notes due August 15, 2007 upon maturity and for general corporate purposes, including specifically, the further development of our businesses.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
Critical Accounting Policies
 
The consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles, which require management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and related notes. Actual results can and will differ from estimates. These differences could be material to the financial statements.
 
We believe our application of accounting policies and the estimates required therein are reasonable. These accounting policies and estimates are constantly re-evaluated, and adjustments are made when facts and circumstances dictate a change. Historically, we have found our application of accounting policies to be appropriate, and actual results have not differed materially from those determined using necessary estimates.
 
Our management believes our critical accounting policies (policies that are both material to the financial condition and results of operations and require management’s most difficult, subjective or complex judgments) are our valuation of financial instruments and our use of estimates related to compensation and benefits during the year.
 
Valuation of Financial Instruments
 
Our financial instruments are primarily recorded at fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). The use of fair value to measure financial instruments is fundamental to our financial statements and is our most critical accounting policy. Unrealized gains or losses are generally recognized in principal transactions in our Consolidated Statement of Earnings. Financial instruments are valued at quoted market prices, if available. For financial instruments that do not have readily determinable fair values through quoted market prices, the determination of fair value is based upon consideration of available information, including types of financial instruments, current financial information, restrictions on dispositions, fair values of underlying financial instruments and quotations for similar instruments.
 
We adopted FASB 157 and FASB 159, as of the beginning of 2007. See Notes 1 and 4 to the Consolidated Financial Statements in Part I, Item 1 of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2007 for further information on FASB 157 and FASB 159, including the impact of adoption.
 
Compensation and Benefits
 
The use of estimates is important in determining compensation and benefits expenses for interim and year end periods. A substantial portion of our compensation and benefits represents discretionary bonuses, which are fixed at year end. In addition to the level of net revenues, our overall compensation expense in any given year is influenced by prevailing labor markets, revenue mix and our use of equity-based compensation programs. We believe the most appropriate way to allocate estimated annual discretionary bonuses among interim periods is in proportion to projected net revenues earned. Consequently, we have generally accrued interim compensation and benefits based on annual targeted compensation ratios, taking into account the guidance contained in FASB 123R regarding the timing of expense recognition for non retirement-eligible and retirement-eligible employees.
 
Reportable Business Segments
 
For presentation purposes, the remainder of “Results of Operations” is presented on a detailed product and expense basis rather than on a business segment basis.
 
Our earnings are subject to wide fluctuations since many factors over which we have little or no control, particularly the overall volume of trading, the volatility and general level of market prices, and the number

and size of investment banking transactions may significantly affect our operations. The following provides a summary of revenues by source for the past three years.
 
Since April 2, 2007 we have been operating in three business segments, Capital Markets, Asset Management and High Yield Trading. Our Capital Markets reportable segment includes our traditional securities and investment banking activities. It is managed as a single operating segment that provides the research, sales, trading and investment banking effort for various fixed income, equity and advisory products and services. The Capital Markets segment comprises many divisions, with extensive interactions among each. In addition, we voluntarily choose to disclose our Asset Management segment, even though it is currently an “immaterial non-reportable” segment as defined by FASB 131, Disclosures about Segments of an Enterprise and Related Information. The Asset Management segment is primarily comprised of operating activities related to our non-integrated asset management businesses including Clear Lake CLO, Victoria Falls CLO, Summit Lake CLO, Diamond Lake CLO, Jefferies RTS Fund, Jefferies Paragon Fund and Jefferies Buckeye Fund. This segment does not include activity associated with our international asset management, which is managed by its own desk manager and is included as an integrated component of the Capital Markets reportable segment. On April 2, 2007 we consolidated our secondary market trading activities previously performed by our High Yield division and our High Yield Funds in Jefferies High Yield Trading LLC, or JHYT. Our High Yield Trading segment comprises secondary sales and trading of high yield securities and special situation securities, including bank debt, post-reorganization equity, public and private equity, equity derivatives, credit default swaps and other financial instruments. It makes markets in high yield and distressed securities and provides research coverage on these types of securities. We own 50% of the voting securities of the parent entity of JHYT and will consolidate JHYT for financial reporting purposes beginning with the second quarter of 2007.

First Quarter 2007 versus First Quarter 2006
 
Overview
 
Revenues increased $99.2 million, or 19%, to $623.3 million, compared to $524.1 million for the first quarter of 2006. The increase was primarily due to a $42.4 million, or 33%, increase in investment banking revenue, and a $87.4 million, or 77%, increase in interest revenues (net interest income which is interest revenue less interest expense decreased $8.4 million), partially offset by a $12.2 million, or 5%, decrease in equity and fixed income and commodities revenues, and a $18.3 million, or 45%, decrease in asset management fees and investment income from managed funds.
 
Equity Product Revenue
 
Equity product revenue is comprised of equity (including principal transaction and commission revenue), correspondent clearing and prime brokerage, and execution product revenues. Equity product revenue was $173.1 million, which was relatively comparable to the first quarter of 2006. Although equity product revenue was relatively flat for the quarter, we had strong contributions from most of our equity revenue products. Specifically, we had solid contributions from our cash equity product, proprietary trading and investing, equity derivatives and algorithmic trading. In addition, we began revenue generation from our prime brokerage effort which was launched in October of 2006.
 
Fixed Income & Commodities Revenue
 
Fixed income and commodities revenue is comprised of high yield, investment grade fixed income, convertible and commodities product revenue. Fixed income and commodities revenue was $56.5 million, down 18% over last year’s quarter. The decrease was driven by decreased activity in the high yield and commodity markets and offset by increased market share in investment grade fixed income. High yield and commodities product revenue both posted positive results for the quarter, however, product revenues decreased from last year’s record first quarter, due to lower trading results in energy related products. Investment grade income revenues increased despite the increase in short term interest rates and a flattening yield curve.

Capital markets revenues, which consist primarily of debt, equity and convertible financing services, were $90.3 million, an increase of 92% from the first quarter of 2006. The increase in capital markets revenues was led by a strong performance in debt underwritings as well as the expansion of our investment banking activities outside the United States.
 
Revenues from advisory activities were $79.8 million, which was relatively comparable to the first quarter of 2006. Although advisory related revenue was relatively flat for the quarter, we had strong contributions attributable to services rendered on assignments in the technology, industrial, energy and aerospace and defense sectors.
 
Asset Management Fee Revenue
 
Asset management revenue includes revenues from management, administrative and performance fees from funds managed by us, revenues from asset management and performance fees from third-party managed funds, and investment revenue from our investments in these funds. Asset management revenues were $22.5 million, down 45% over the first quarter of 2006. The decrease in asset management revenue was a result of (i) a decrease in managed equity assets from the prior quarter, and (2) a strong prior period performance from our managed equity assets; such performance was not replicated during the current quarter.

The increase in net cash flow in during the first quarter of 2007 is primarily due to the commencement of the Clear Lake CLO and increased assets under management from our international convertible bond funds.
 
Net Interest Revenue
 
Interest income increased $87.4 million primarily as a result of increased stock borrowing activity and increases in interest rates, and interest expense increased by $95.8 million primarily as a result of increased stock lending activity, increases in interest rates, the issuance of our $500 million of senior unsecured debentures, our $125 million in Series A Mandatorily Convertible Preferred Stock and the financing of higher financial instrument levels.

Compensation and Benefits
 
Compensation and benefits decreased $5.1 million, or 2%, versus the 1% increase in net revenues. The decrease was primarily due to our ability to leverage our investment banking platform.
 
Average employee headcount increased 12% from 2,030 during the first quarter of 2006 to 2,265 during the first quarter of 2007. The ratio of compensation to net revenues was approximately 54.4% for the first quarter of 2007 as compared to 56.0% for the first quarter of 2006.
 
Non-Personnel Expenses
 
Non-personnel expense was $87.7 million for the first quarter of 2007 versus $85.3 million for the first quarter of 2006 or 20.9% of net revenues for the first quarter of 2007 versus 20.5% of net revenues for the first quarter of 2006. The increase in non-personnel expenses is consistent with our revenue growth and primarily attributable to increased technology and communications, occupancy, legal and compliance and other costs associated with higher levels of business activity.
 
Earnings before Income Taxes, Minority Interest, and Cumulative Effect of Change in Accounting Principle, Net
 
Earnings before income taxes, minority interest and cumulative effect of change in accounting principle, net, were up $6.1 million, or 6%, to $103.5 million, compared to $97.4 million for the first quarter of 2006. The effective tax rates were approximately 39.3% for the first quarter of 2007 and 39.5% for the first quarter of 2006.
 
Earnings per Share
 
Basic net earnings per share were $0.44 for the first quarter of 2007 on 140,897,000 shares compared to $0.45 in the first quarter of 2006 on 130,358,000 shares. Diluted net earnings per share were $0.42 for the first quarter of 2007 on 152,058,000 shares compared to $0.41 in the first quarter of 2006 on 142,942,000 shares. The diluted earnings per share calculation for the first quarter of 2007 includes an addition of $1.0 million to net earnings for preferred dividends. The dividend is recorded as a component of interest expense as the Series A convertible preferred stock is treated as debt in accordance with FASB 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity.
 
Liquidity, Financial Condition and Capital Resources
 
Our Chief Financial Officer and Treasurer are responsible for developing and implementing our liquidity, funding and capital management strategies. These policies are determined by the nature of our day to day business operations, business growth possibilities, regulatory obligations, and liquidity requirements.
 
Our actual level of capital, total assets, and financial leverage are a function of a number of factors, including, asset composition, business initiatives, regulatory requirements and cost availability of both long term and short term funding. We have historically maintained a highly liquid balance sheet, with a substantial portion of our total assets consisting of cash, highly liquid marketable securities and short-term receivables, arising principally from traditional securities brokerage activity. The highly liquid nature of these assets provides us with flexibility in financing and managing our business.

We had $110.0 million and $0 of outstanding secured bank loans as of March 31, 2007 and December 31, 2006, respectively. Unsecured bank loans are typically overnight loans used to finance financial instruments owned or clearing related balances. We had $121.9 million and $0 of outstanding unsecured bank loans as of March 31, 2007 and December 31, 2006, respectively. Average daily bank loans for the quarter ended March 31, 2007 and year ended December 31, 2006 were $171.4 million and $12.4 million, respectively.
 
A substantial portion of our assets are liquid, consisting of cash or assets readily convertible into cash. The majority of securities positions (both long and short) in our trading accounts are readily marketable and actively traded. In addition, receivables from brokers and dealers are primarily current open transactions or securities borrowed transactions, which are typically settled or closed out within a few days. Receivable from customers includes margin balances and amounts due on transactions in the process of settlement. Most of our receivables are secured by marketable securities.
 
Our assets are funded by equity capital, senior debt, mandatorily redeemable convertible preferred stock, securities loaned, customer free credit balances, bank loans and other payables. Bank loans represent temporary (usually overnight) secured and unsecured short-term borrowings, which are generally payable on demand. We have arrangements with banks for unsecured financing of up to $537 million. Secured bank loans are collateralized by a combination of customer, non-customer and firm securities. We have always been able to obtain necessary short-term borrowings in the past and believe that we will continue to be able to do so in the future. Additionally, we have $264.3 million in letters of credit outstanding as of March 31, 2007, which are used in the normal course of business mostly to satisfy various collateral requirements in lieu of depositing cash or securities.
 
Excess Liquidity
 
Our policy is to maintain excess liquidity to cover all expected cash outflows for one year in a stressed liquidity environment. Liquid resources consist of unrestricted cash and unencumbered assets that are readily convertible into cash on a secured basis on short notice. Certain investments are also readily convertible to cash. In addition, we have $537 million of unsecured, uncommitted lines of credit with various banks.

Management believes these resources provide sufficient excess liquidity to cover all expected cash outflows, inclusive of potential equity repurchases, for one year during a stressed liquidity environment. Expected cash outflows include:
 
  •  The repayment of our unsecured debt maturing within twelve months ($100 million outstanding at March 31, 2007);
 
  •  The payment of interest expense (including dividends on our mandatorily redeemable convertible preferred stock) on our long term debt;
 
  •  The anticipated funding of outstanding investment commitments;
 
  •  The anticipated fixed costs over the next 12 months;
 
  •  Potential stock repurchases; and
 
  •  Certain accrued expenses and other liabilities
 
Analysis of Financial Condition and Capital Resources
 
Financial Condition
 
As previously discussed, we have historically maintained a highly liquid balance sheet, with a substantial portion of our total assets consisting of cash, highly liquid marketable securities and short-term receivables, arising principally from traditional securities brokerage activity. Total assets increased $7,870.0 million, or 44%, from $17,825.5 million at December 31, 2006 to $25,695.5 million at March 31, 2007. Our financial instruments owned, including securities pledged to creditors, increased $2,233.4 million, while our financial instruments sold, not yet purchased increased $1,339.4 million. Our securities borrowed and securities purchased under agreements to resell increased $5,272.3 million, while our securities loaned and securities sold under agreements to repurchase increased $5,878.1 million.

Tangible stockholders’ equity, pro forma book value per share, tangible book value per share and pro forma tangible book value per share are “non-GAAP financial measures.” A “non-GAAP financial measure” is a numerical measure of financial performance that includes adjustments to the most directly comparable measure calculated and presented in accordance with GAAP, or for which there is no specific GAAP guidance. We calculate tangible stockholders’ equity as stockholders’ equity less intangible assets. We calculate pro forma book value per share as stockholders’ equity plus the projected deferred tax benefit on the vested portion of restricted stock and RSUs divided by common shares outstanding adjusted for shares not yet issued to the extent of the related expense amortization and shares issued to the extent the related expense has not been amortized. We calculate tangible book value per share by dividing tangible stockholders’ equity by common stock outstanding. We calculate pro forma tangible book value per share by dividing tangible stockholders’ equity plus the projected deferred tax benefit on the vested portion of restricted stock and RSUs by common shares outstanding adjusted for shares not yet issued to the extent of the related expense amortization and shares issued to the extent the related expense has not been amortized. We consider these

ratios as meaningful measurements of our financial condition and believe they provide investors with additional metrics to comparatively assess the fair value of our stock.
 
Capital Resources
 
We had total long term capital of $3.0 billion and $2.9 billion as of March 31, 2007 and December 31, 2006, respectively, resulting in a long-term debt to total capital ratio of 39% and 41%, respectively. Our total capital base as of March 31, 2007 and December 31, 2006 was as follows (in thousands):
 
                 
    March 31,
    December 31,

Total Capital
  $ 2,983,437     $ 2,874,649  
                 
 
Our ability to support increases in total assets is largely a function of our ability to obtain short term secured and unsecured funding, primarily through securities lending, and through our $537 million of uncommitted unsecured bank lines. Our ability is further enhanced by the cash proceeds from the $500 million senior unsecured bonds and $125 million in series A preferred stock, both issued in the first quarter of 2006.
 
At March 31, 2007, our senior debt, net of unamortized discount, consisted of contractual principal payments (adjusted for amortization) of $492.3 million, $348.4 million, $328.7 million and $100.0 million due in 2036, 2016, 2012 and 2007, respectively.
 
We rely upon our cash holdings and external sources to finance a significant portion of our day-to-day operations. Access to these external sources, as well as the cost of that financing, is dependent upon various factors, including our debt ratings. Our current debt ratings are dependent upon many factors, including operating results, operating margins, earnings trend and volatility, balance sheet composition, liquidity and liquidity management, our capital structure, our overall risk management, business diversification and our market share and competitive position in the markets in which we operate.
 
Our long term debt ratings are as follows:
 
         
    Rating  
 
Moody’s Investors Service
    Baa1  
Standard and Poor’s
    BBB+  
Fitch Ratings
    BBB+  
 
In May 2007 Moody’s Investors Service raised to positive from stable the rating outlook on our long-term debt.
 
Net Capital
 
Jefferies and Jefferies Execution are subject to the net capital requirements of the SEC and other regulators, which are designed to measure the general financial soundness and liquidity of broker-dealers. Jefferies and Jefferies Execution use the alternative method of calculation.
 
As of March 31, 2007, Jefferies’ and Jefferies Execution’s net capital and excess net capital were as follows (in thousands of dollars):

Guarantees
 
As of March 31, 2007, we had outstanding guarantees of $20.0 million relating to an undrawn bank credit obligation of an associated investment fund in which we have an interest. In addition, we guarantee up to an aggregate of approximately $36.0 million in bank loans committed to an employee parallel fund of Jefferies Capital Partners IV L.P. (“Fund IV”).
 
We have guaranteed the performance of JIL and JFP to their trading counterparties and various banks and other entities, which provide clearing and credit services to JIL and JFP. Also, we have provided a guarantee to a third-party bank in connection with the bank’s extension of 500 million Japanese yen (approximately $4.2 million) to Jefferies (Japan) Limited. In addition, as of March 31, 2007, we had commitments to invest up to $266.8 million in various investments, including $215.0 million in Jefferies Finance LLC, $39.4 million in Fund IV and $12.4 million in other investments.
 
Leverage Ratios
 
The following table presents total assets, adjusted assets, and net adjusted assets with the resulting leverage ratios as of March 31, 2007 and December 31, 2006. With respect to leverage ratio, we believe that net adjusted leverage is the most relevant measure, given the low-risk, collateralized nature of our securities borrowed and segregated cash assets.

Stock Repurchases
 
During the first quarter of 2007, we purchased 589,793 shares of our common stock for $16.7 million in connection with our stock compensation plans which allow participants to use shares to pay the exercise price of options exercised and to use shares to satisfy tax liabilities arising from the exercise of options or the vesting of restricted stock. The number above does not include unvested shares forfeited back to us pursuant to the terms of our stock compensation plans. We believe that we have sufficient liquidity and capital resources to make these repurchases without any material adverse effect on us.

DESCRIPTION OF THE NOTES AND THE DEBENTURES
 
General
 
The following description of the notes and the debentures we are offering supplements, and to the extent inconsistent therewith supersedes, the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus. We refer you to that description.
 
We will issue the notes and the debentures under an indenture dated as of March 12, 2002 between us and The Bank of New York, as trustee, as supplemented by a first supplemental indenture, dated as of July 15, 2003. We have normal banking relationships with The Bank of New York.
 
We do not currently intend to list the notes or the debentures on any securities exchange or to seek approval for their quotation through any automated quotation system. We cannot assure you that an active public market for the notes or the debentures will develop. The absence of an active public trading market could have an adverse effect on the liquidity and value of the notes and the debentures.
 
We may from time to time, without giving notice to or seeking the consent of the holders of the notes or debentures, as the case may be, issue additional notes or debentures having the same ranking and the same interest rate, maturity and other terms as the notes or the debentures, except for the issue price and the issue date. Any additional notes or debentures having such similar terms, together with the notes or the debentures offered hereby, as the case may be, will constitute a single series of senior notes or senior debentures under the indenture.
 
Principal, Maturity and Interest
 
The initial aggregate principal amount of the notes is $          . Each note will mature on          , 2014 and will bear interest at the rate per annum shown on the cover page of this prospectus supplement. The initial aggregate principal amount of the debentures is $          . Each debenture will mature on          , 2027 and will bear interest at the rate per annum shown on the cover page of this prospectus supplement. Interest on the notes and the debentures will accrue from the date of original issuance, or from the most recent interest payment date to which interest has been paid or provided for. We will pay interest on the notes and the debentures on           and           of each year, commencing          , 2007 to holders of record at the close of business on the immediately preceding           and          , respectively.
 
Interest will be calculated on the basis of a 360-day year comprised of twelve 30-day months. Interest on the notes and the debentures will be paid by check mailed to the persons in whose names the notes or the debentures, as the case may be, are registered at the close of business on the applicable record date or, at our option, by wire transfer to accounts maintained by such persons with a bank located in the United States. The principal of the notes and the debentures will be paid upon surrender of the notes or the debentures, as the case may be, at the corporate trust office of the trustee. For so long as the notes and the debentures are represented by global notes and global debentures, respectively, we will make payments of interest by wire transfer to The Depository Trust Company (DTC) or its nominee, as the case may be, which will distribute payments to beneficial holders in accordance with its customary procedures. We will not pay additional amounts for taxes, as described in “Description of Debt Securities — Payment of Additional Amounts.”
 
Neither the notes nor the debentures are entitled to any sinking fund. The provisions of the indenture described in the accompanying prospectus under “Description of Debt Securities — Defeasance” will apply to the notes and the debentures.
 
Ranking
 
The notes and the debentures will be senior unsecured obligations, each ranking equally with all of our existing and future senior indebtedness and senior to any future subordinated indebtedness.


S-22


Table of Contents

Optional Redemption
 
The notes and the debentures will be redeemable, in whole at any time or in part from time to time, at our option at a redemption price equal to the greater of:
 
(i) 100% of the principal amount of the notes or the debentures to be redeemed; or
 
(ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any such portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus           basis points with respect to the notes and           basis points with respect to the debentures.
 
plus, in each case, accrued interest thereon to the date of redemption. Notwithstanding the foregoing, installments of interest on notes or debentures that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date according to the notes or the debentures and the indenture.
 
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the notes or the debentures to be redeemed that would be utilized, at the time of selection in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such debentures.
 
“Comparable Treasury Price” means, with respect to any redemption date, (i) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if only one Reference Treasury Dealer Quotation is received, such quotation.
 
“Quotation Agent” means the Reference Treasury Dealer appointed by us.
 
“Reference Treasury Dealer” means (i) Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated (or their respective affiliates that are Primary Treasury Dealers) and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by us.
 
“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by such reference treasury dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.
 
“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price of such redemption date.
 
Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each registered holder of the notes or the debentures to be redeemed. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or the debentures or portions thereof called for redemption. If less than all of the notes or the debentures are to be redeemed, the notes or the debentures to be redeemed shall be selected by the Trustee by a method the Trustee deems appropriate.

Covenants
 
Limitations on Liens.  The indenture provides that we will not, and will not permit any material subsidiary to, incur, issue, assume or guarantee any indebtedness for borrowed money if such indebtedness is secured by a pledge of, lien on, or security interest in any shares of common stock of any material subsidiary, without providing that each series of senior debt securities and, at our option, any other indebtedness ranking equally and ratably with such indebtedness, is secured equally and ratably with (or prior to) such other secured indebtedness. The indenture defines material subsidiary to be any subsidiary that represents 5% or more of our consolidated net worth as of the date of determination.
 
Limitations on Transactions with Affiliates.  The indenture provides that we will not, and will not permit any subsidiary to, sell, lease, transfer or otherwise dispose of any of our or its properties or assets to, or purchase any property or asset from, or enter into any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any affiliate of ours unless:
 
  •  the transaction with the affiliate is made on terms no less favorable to us or the subsidiary than those that would have been obtained in a comparable transaction with an unrelated person; and
 
  •  in the case of any affiliate transaction involving consideration in excess of $25 million in any fiscal year, we deliver to the trustee a certificate to the effect that our board of directors has determined that the transaction complies with the requirements described in the above bullet point and that the transaction has been approved by a majority of the disinterested members of our board of directors.
 
This covenant will not apply to any employment agreement entered into in the ordinary course of business and consistent with past practices, to any transaction between or among us and our subsidiaries or to transactions entered into prior to the date the notes and the debentures are issued.
 
Limitations on Mergers and Sales of Assets.  The indenture provides that we will not merge or consolidate or transfer or lease our assets substantially as an entirety, and another person may not transfer or lease its assets substantially as an entirety to us, unless:
 
  •  either (1) we are the continuing corporation, or (2) the successor corporation, if other than us, is a U.S. corporation and expressly assumes by supplemental indenture the obligations evidenced by the securities issued pursuant to the indenture; and
 
  •  immediately after the transaction, there would not be any default in the performance of any covenant or condition of the indenture.
 
In the event of any transaction described in and complying with the conditions listed in this covenant in which we are not the continuing entity, the successor person formed or remaining or to which such transfer is made shall succeed to, and be substituted for, and may exercise every right and power of us, and we would be discharged from all obligations and covenants under the indenture and the notes.
 
Book-Entry, Delivery and Form
 
We have obtained the information in this section concerning DTC, Clearstream, Euroclear and the book-entry system and procedures from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information.
 
The notes and the debentures will be issued as fully-registered global notes and global debentures which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, which we refer to as “DTC,” and registered, at the request of DTC, in the name of Cede & Co. Beneficial interests in the global notes and the global debentures will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct or indirect participants in DTC. Investors may elect to hold their interests in the global notes and the global debentures through either DTC (in the United States) or (in Europe) through Clearstream Banking S.A., or “Clearstream,” formerly Cedelbank, or through Euroclear Bank S.A./N.V., as operator of the Euroclear System, or “Euroclear.” Investors may hold their interests in the global notes and the global debentures directly if they are participants of such systems, or indirectly through


S-24


Table of Contents

organizations that are participants in these systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold these interests in customers’ securities accounts in the depositaries’ names on the books of DTC. Citibank, N.A. will act as depositary for Clearstream and JPMorgan Chase Bank will act as depositary for Euroclear. We will refer to Citibank and JPMorgan Chase Bank in these capacities as the “U.S. Depositaries.” Beneficial interests in the global notes and the global debentures will be held in denominations of $5,000 and integral multiples of $1,000 in excess thereof. Except as set forth below, the global notes and the global debentures may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.
 
Notes represented by a global note and the debentures represented by a global debenture can be exchanged for definitive notes or debentures, as the case may be, in registered form only if:
 
  •  DTC notifies us that it is unwilling or unable to continue as depositary for that global note or global debenture and we do not appoint a successor depositary within 90 days after receiving that notice;
 
  •  at any time DTC ceases to be a clearing agency registered under the Securities Exchange Act of 1934 and we do not appoint a successor depositary within 90 days after becoming aware that DTC has ceased to be registered as a clearing agency;
 
  •  we in our sole discretion determine that that global note or global debenture will be exchangeable for definitive notes or debentures, as the case may be, in registered form and notify the trustee of our decision; or
 
  •  an event of default with respect to the notes or the debentures represented by that global note or global debenture, as the case may be, has occurred and is continuing.
 
A global note or global debenture that can be exchanged as described in the preceding sentence will be exchanged for definitive notes or debentures, as the case may be, issued in denominations of $5,000 and integral multiples of $1,000 in excess thereof in registered form for the same aggregate amount. The definitive notes or debentures will be registered in the names of the owners of the beneficial interests in the global note or global debenture as directed by DTC.
 
We will make principal and interest payments on all notes represented by a global note and all debentures represented by a global debenture to the paying agent which in turn will make payment to DTC or its nominee, as the case may be, as the sole registered owner and the sole holder of the notes represented by the global note or the debentures represented by a global debenture, as the case may be, for all purposes under the indenture. Accordingly, we, the trustee and any paying agent will have no responsibility or liability for:
 
  •  any aspect of DTC’s records relating to, or payments made on account of, beneficial ownership interests in a note represented by a global note or a debenture represented by a global debenture;
 
  •  any other aspect of the relationship between DTC and its participants or the relationship between those participants and the owners of beneficial interests in a global note or a global debenture held through those participants; or
 
  •  the maintenance, supervision or review of any of DTC’s records relating to those beneficial ownership interests.
 
DTC has advised us that its current practice is to credit participants’ accounts on each payment date with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global note or global debenture as shown on DTC’s records, upon DTC’s receipt of funds and corresponding detail information. The underwriters will initially designate the accounts to be credited. Payments by participants to owners of beneficial interests in a global note or a global debenture will be governed by standing instructions and customary practices, as is the case with securities held for customer accounts registered in “street name,” and will be the sole responsibility of those participants. Book-entry notes and debentures may be more difficult to pledge because of the lack of a physical debenture.


S-25


Table of Contents

DTC
 
So long as DTC or its nominee is the registered owner of a global note or a global debenture, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the notes and the debentures represented by that global note or global debenture for all purposes of the indenture. Owners of beneficial interests in the notes and the debentures will not be entitled to have the notes or the debentures registered in their names, will not receive or be entitled to receive physical delivery of the notes or the debentures in definitive form and will not be considered owners or holders of notes or debentures under the indenture. Accordingly, each person owning a beneficial interest in a global note or a global debenture must rely on the procedures of DTC and, if that person is not a DTC participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder of notes or debentures. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of the securities in certificated form. These laws may impair the ability to transfer beneficial interests in a global debenture. Beneficial owners may experience delays in receiving distributions on their notes or debentures since distributions will initially be made to DTC and must then be transferred through the chain of intermediaries to the beneficial owner’s account.
 
We understand that, under existing industry practices, if we request holders to take any action, or if an owner of a beneficial interest in a global note or a global debenture desires to take any action which a holder is entitled to take under the indenture, then DTC would authorize the participants holding the relevant beneficial interests to take that action and those participants would authorize the beneficial owners owning through such participants to take that action or would otherwise act upon the instructions of beneficial owners owning through them.
 
Beneficial interests in a global note or a global debenture will be shown on, and transfers of those ownership interests will be effected only through, records maintained by DTC and its participants for that global note or global debenture. The conveyance of notices and other communications by DTC to its participants and by its participants to owners of beneficial interests in the notes and the debentures will be governed by arrangements among them, subject to any statutory or regulatory requirements in effect.
 
DTC has advised us that it is a limited-purpose trust company organized under the New York banking law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Securities Exchange Act of 1934.
 
DTC holds the securities of its participants and facilitates the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of its participants. The electronic book-entry system eliminates the need for physical certificates. DTC’s participants include securities brokers and dealers, including the underwriters, banks, trust companies, clearing corporations and certain other organizations, some of which, and/or their representatives, own DTC. Banks, brokers, dealers, trust companies and others that clear through or maintain a custodial relationship with a participant, either directly or indirectly, also have access to DTC’s book-entry system. The rules applicable to DTC and its participants are on file with the Securities and Exchange Commission.
 
DTC has advised us that the above information with respect to DTC has been provided to its participants and other members of the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.
 
Clearstream
 
Clearstream has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations, or “Clearstream Participants,” and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and

Table of Contents

securities lending and borrowing. Clearstream interfaces with domestic securities markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Clearstream’s U.S. Participants are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.
 
Distributions with respect to notes and debentures held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures, to the extent received by the U.S. Depositary for Clearstream.
 
Euroclear
 
Euroclear has advised us that it was created in 1968 to hold securities for participants of Euroclear, or “Euroclear Participants,” and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear performs various other services, including securities lending and borrowing and interacts with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V., or the “Euroclear Operator,” under contract with Euroclear plc, a U.K. corporation. All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not Euroclear plc. Euroclear plc establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.
 
The Euroclear Operator is a Belgian bank. As such it is regulated by the Belgian Banking and Finance Commission.
 
Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law, which we will refer to in this prospectus supplement as the “Terms and Conditions.” The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants.
 
Distributions with respect to notes and debentures held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the U.S. Depositary for Euroclear.
 
Euroclear has further advised us that investors that acquire, hold and transfer interests in the notes and the debentures by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global debentures.
 
Global Clearance and Settlement Procedures
 
Initial settlement for the notes and the debentures will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and


S-27


Table of Contents

will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.
 
Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream Participants or Euroclear Participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. Depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. Depositary to take action to effect final settlement on its behalf by delivering or receiving debentures through DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to their respective U.S. Depositaries.
 
Because of time-zone differences, credits of notes and debentures received through Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such notes or such debentures settled during such processing will be reported to the relevant Euroclear Participants or Clearstream Participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of notes or debentures by or through a Clearstream Participant or a Euroclear Participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.
 
Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of notes and debentures among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be modified or discontinued at any time. Neither we nor the paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

MATERIAL UNITED STATES FEDERAL TAX CONSIDERATIONS
 
This section describes the material United States federal income tax consequences of owning the notes and the debentures we are offering. It applies only to a holder that acquires notes or debentures in the initial offering at the offering price listed on the cover page hereof and that holds its notes or debentures as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”). This section does not apply to a holder that is a member of a class of holders subject to special rules, such as:
 
  •  a dealer in securities or currencies;
 
  •  a trader in securities that elects to use a mark-to-market method of accounting for its securities holdings;
 
  •  a bank or other financial institution;
 
  •  an insurance company;
 
  •  a tax-exempt organization;
 
  •  a person that owns notes or debentures that are a hedge or that are hedged against interest rate risks;
 
  •  a person that owns notes or debentures as part of a straddle or conversion transaction for tax purposes;
 
  •  a United States holder (as defined below) whose functional currency for tax purposes is not the U.S. dollar; or
 
  •  except as specifically noted, a United States alien holder (as defined below) that holds the notes or the debentures in connection with a United States trade or business.
 
This section is based on the Code, its legislative history, existing and proposed Treasury regulations under the Code, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis. This discussion does not address any tax consequences arising under any state, local or foreign law.
 
If a partnership or an entity treated as a partnership holds the notes or the debentures, the United States federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. A partner in a partnership or an entity treated as a partnership holding the notes or the debentures should consult its tax advisor with regard to the United States federal income tax treatment of an investment in the notes or the debentures.
 
The discussion in this section is based in part on our determination that there is no more than a remote likelihood that we would exercise our right to redeem the notes or the debentures in circumstances where the amount that we would have to pay in redemption was based on the sum of the present values of the remaining scheduled payments of interest and principal on the notes or the debentures, as the case may be, and that there is more than a remote likelihood that we will exercise our right to redeem the notes or the debentures in circumstances where the amount that we would have to pay would equal 100% of the principal amount of the notes or the debentures, as the case may be, plus accrued interest thereon to the date of redemption. Our determination that there is no more than a remote likelihood that we would redeem the notes or the debentures in circumstances where the amount we would have to pay in redemption is based on the present values of the remaining scheduled payments of interest and principal on the notes or the debentures is binding on holders of the notes or the debentures, unless a holder discloses to the Internal Revenue Service, in the manner required by applicable Treasury regulations, that the holder is taking a different position. It is possible that the Internal Revenue Service may take a different position regarding the remoteness of the likelihood of redemptions, in which case, if the position of the Internal Revenue Service were sustained, the timing, amount and character of income recognized with respect to a note or a debenture may be substantially different than described herein, and a holder may be required to recognize income significantly in excess of payments received and may be required to treat as interest income all or a portion of any gain recognized on a disposition of a note or a debenture. This discussion assumes that the Internal Revenue Service will not take a different position, or,


S-29


Table of Contents

if it takes a different position, that such position will not be sustained. Prospective purchasers should consult their own tax advisors as to the tax considerations that relate to the likelihood of redemption.
 
Holders considering the purchase of notes or debentures should consult their own tax advisors concerning the consequences of purchasing, owning and disposing of notes or debentures in their particular circumstances under the Code and the laws of any other taxing jurisdiction.
 
United States Holders
 
This subsection describes the tax consequences to a United States holder. A holder is a United States holder if that holder is a beneficial owner of a note or a debenture and is or is treated for United States federal income tax purposes as:
 
  •  a citizen or resident of the United States;
 
  •  a corporation or an entity treated as a corporation created or organized under the laws of the United States or any State thereof or the District of Columbia;
 
  •  an estate whose income is subject to United States federal income tax regardless of its source; or
 
  •  a trust if (i) a United States court can exercise primary supervision over the trust’s administration and one or more United States persons are authorized to control all substantial decisions of the trust or (ii) the trust was in existence on August 20, 1996 and has elected to continue to be treated as a United States person.
 
Holders that are not United States holders should refer to “ — United States Alien Holders” below.
 
Payments of Interest.  We expect that the first price at which a substantial amount of the notes or of the debentures is sold to persons (other than bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) will equal the stated principal amount of the notes or the debentures, as the case may be, or an amount which is at a de minimis discount thereto. If that is the case, stated interest payments on the notes or the debentures generally will be taxable as ordinary income at the time the interest accrues or is received, in accordance with a holder’s regular method of accounting for United States federal income tax purposes.
 
Purchase, Sale and Retirement of the Notes or the Debentures.  A holder’s tax basis in a note or a debenture will generally be the cost of the note or the debenture. A holder generally will recognize capital gain or loss on the sale, retirement or other taxable disposition of a note or a debenture equal to the difference between the amount realized on the sale, retirement or other taxable disposition and the holder’s tax basis in the note or the debenture. A holder will recognize capital gain or loss at the time of such sale, retirement or other taxable disposition, except that proceeds attributable to accrued but unpaid interest will be recognized as ordinary interest income to the extent that the holder has not previously included the accrued interest in income. Capital gain of a noncorporate United States holder that is recognized in a taxable year beginning before January 1, 2011 is generally taxed at a maximum rate of 15% where the holder has a holding period greater than one year. The deductibility of capital losses is subject to limitations.
 
United States Alien Holders
 
This subsection describes the tax consequences to a United States alien holder. A holder is a United States alien holder if that holder is the beneficial owner of a note or a debenture and is, for United States federal income tax purposes, an individual, corporation, estate or trust that is not a United States holder.
 
This subsection does not apply to a United States holder.
 
Under United States federal income tax law, and subject to the discussion of backup withholding below, if a holder is a United States alien holder of a note or a debenture, we and other United States paying agents (collectively referred to as “U.S. Payors”) generally will not be required to deduct a 30% United States


S-30


Table of Contents

withholding tax from payments on the notes or the debentures to the holder if, in the case of payments of interest:
 
(a) the holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock that are entitled to vote;
 
(b) the holder is not a controlled foreign corporation that is related to us through stock ownership; and
 
(c) the U.S. Payor does not have actual knowledge or reason to know that the holder is a United States person and:
 
(i) the holder has furnished to the U.S. Payor an Internal Revenue Service Form W-8BEN or an acceptable substitute form upon which the holder certifies, under penalties of perjury, that the holder is (or, in the case of a United States alien holder that is a partnership or an estate or trust, such forms certifying that each partner in the partnership or beneficiary of the estate or trust is) a non-United States person;
 
(ii) the U.S. Payor has received a withholding certificate (furnished on an appropriate Internal Revenue Service Form W-8 or an acceptable substitute form) from a person claiming to be:
 
(A) a withholding foreign partnership (generally a foreign partnership that has entered into an agreement with the Internal Revenue Service to assume primary withholding responsibility with respect to distributions and guaranteed payments it makes to its partners);
 
(B) a qualified intermediary (generally a non-United States financial institution or clearing organization or a non-United States branch or office of a United States financial institution or clearing organization that is a party to a withholding agreement with the Internal Revenue Service); or
 
(C) a U.S. branch of a non-United States bank or of a non-United States insurance company, that has agreed to be treated as a United States person for withholding purposes,
 
and the withholding foreign partnership, qualified intermediary or U.S. branch has received documentation upon which it may rely to treat the payment as made to a non-United States person that is, for United States federal income tax purposes, the beneficial owner of the payments on the notes or the debentures in accordance with U.S. Treasury regulations (or, in the case of a withholding foreign partnership or a qualified intermediary, in accordance with its agreement with the Internal Revenue Service),
 
(iii) the U.S. Payor receives a statement from a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the notes or the debentures on behalf of the United States alien holder,
 
(A) certifying to the U.S. Payor under penalties of perjury that an Internal Revenue Service Form W-8BEN or an acceptable substitute form has been received from the holder by it or by a similar financial institution between it and the holder, and
 
(B) to which is attached a copy of Internal Revenue Service Form W-8BEN or acceptable substitute form, or
 
(iv) the U.S. Payor otherwise possesses documentation upon which it may rely to treat the payments as made to a non-United States person that is, for United States federal income tax purposes, the beneficial owner of the payments on the notes or the debentures in accordance with U.S. Treasury regulations.
 
Subject to the discussion below regarding effectively connected interest, a non-United States alien holder that does not meet the conditions set forth above will be subject to United States federal withholding tax at the applicable rate (currently 30%) with respect to payments of interest, unless the United States alien holder is entitled to a reduction in or an exemption from withholding tax on interest under a tax treaty between the


S-31


Table of Contents

United States and the United States alien holder’s country of residence. To claim such a reduction or exemption, a United States alien holder must generally complete an Internal Revenue Service Form W-8BEN and claim this exemption on the form. In some cases, a United States alien holder may instead be permitted to provide documentary evidence of its claim to the intermediary, or a qualified intermediary may already have some or all of the necessary evidence in its files.
 
Interest Treated as Effectively Connected
 
Notwithstanding the foregoing discussion and subject to the discussion below regarding backup withholding, interest on a United States alien holder’s notes or debentures will not be subject to United States federal withholding tax if:
 
  •  the United States alien holder is engaged in the conduct of a trade or business in the United States;
 
  •  interest income on the United States alien holder’s notes or debentures is effectively connected to the conduct of its trade or business in the United States; and
 
  •  the United States alien holder has certified to the paying agent on an Internal Revenue Service Form W-8ECI that it is exempt from withholding tax because the interest income on its notes or debentures will be effectively connected with the conduct of its trade or business in the United States.
 
Interest income on the notes or the debentures that is treated as effectively connected with a United States alien holder’s conduct of a trade or business in the United States (and, if a “permanent establishment” clause in a tax treaty applies, is attributable to a permanent establishment in the United States) will be includable in the income of the United States alien holder for regular United States federal income tax purposes and taxed at the same rates that apply to the United States holders (and, in the case of a United States alien holder that is a corporation for United States federal income tax purposes, may also be subject to branch profits tax at a 30% rate, or such lower rate as is provided under an applicable tax treaty).
 
Sale or Other Disposition of the Notes or the Debentures
 
Subject to the discussion of backup withholding below, United States alien holder will generally not be subject to United States federal income tax or withholding tax on gain recognized on the sale, retirement or other taxable disposition of a note or a debenture unless such gain is effectively connected with a United States trade or business of such United States alien holder, and, in the case of a qualified resident of a country having an applicable income tax treaty with the United States, such gain is attributable to a U.S. permanent establishment of such United States alien holder. However, an individual United States alien holder who is present in the United States for 183 days or more in the taxable year of the disposition of a note or a debenture and satisfies certain other conditions will be subject to United States federal income tax on any gain recognized (subject to offset by certain United States — source losses) at a 30% rate or such lower rate as is provided under an applicable treaty.
 
Federal Estate Taxes
 
Furthermore, a note or a debenture held by an individual who at death is not a citizen or resident of the United States will not be includible in the individual’s gross estate for United States federal estate tax purposes if:
 
  •  the decedent did not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote at the time of death; and
 
  •  the income on the note or the debenture would not have been effectively connected with a United States trade or business of the decedent at the same time.
 
Backup Withholding and Information Reporting
 
In general, in the case of a noncorporate United States holder, we and other payors are required to report to the Internal Revenue Service all payments of principal, premium, if any, and interest on the notes or the


S-32


Table of Contents

debentures. In addition, we and other payors are required to report to the Internal Revenue Service any payment of proceeds of the sale of the notes or the debentures before maturity within the United States. Additionally, backup withholding at the applicable rate (currently 28%) will apply to any payments if the holder fails to provide an accurate taxpayer identification number, or the holder is notified by the Internal Revenue Service that the holder has failed to report all interest and dividends required to be shown on the holder’s federal income tax returns. In general, a holder may obtain a refund of any amounts withheld under the U.S. backup withholding rules that exceed the holder’s income tax liability by filing a timely refund claim with the Internal Revenue Service.
 
In general, in the case of a United States alien holder, payments of principal, premium, if any, and interest made by us and other payors to the holder will not be subject to backup withholding and information reporting, provided that the certification requirements described above under “ — United States Alien Holders” are satisfied or the holder otherwise establishes an exemption. However, we and other payors are required to report payments of interest on the notes or the debentures on Internal Revenue Service Form 1042-S even if the payments are not otherwise subject to information reporting requirements. In addition, payment of the proceeds from the sale of notes or debentures effected at a United States office of a broker will not be subject to backup withholding and information reporting provided that the broker does not have actual knowledge or reason to know that the holder is a United States person and the holder has furnished to the broker:
 
  •  an appropriate Internal Revenue Service Form W-8 or an acceptable substitute form upon which the holder certifies, under penalties of perjury, that the holder is not a United States person; or
 
  •  other documentation upon which it may rely to treat the payment as made to a non-United States person in accordance with U.S. Treasury regulations; or
 
the holder otherwise establishes an exemption.
 
If a holder fails to establish an exemption and the broker does not possess adequate documentation of the holder’s status as a non-United States person, the payments may be subject to information reporting and backup withholding. However, backup withholding will not apply with respect to payments made to an offshore account maintained by the holder unless the broker has actual knowledge or reason to know that the holder is a United States person.
 
In general, payment of the proceeds from the sale of notes or debentures effected at a foreign office of a broker will not be subject to information reporting or backup withholding. However, a sale effected at a foreign office of a broker will be subject to information reporting and backup withholding if:
 
  •  the proceeds are transferred to an account maintained by the holder in the United States;
 
  •  the payment of proceeds or the confirmation of the sale is mailed to the holder at a United States address; or
 
  •  the sale has some other specified connection with the United States as provided in U.S. Treasury regulations,
 
unless the broker does not have actual knowledge or a reason to know that the holder is a United States person and the documentation requirements described above (relating to a sale of notes or debentures effected at a United States office of a broker) are met or the holder otherwise establishes an exemption.
 
In addition, payment of the proceeds from the sale of notes or debentures effected at a foreign office of a broker will be subject to information reporting if the broker is:
 
  •  a United States person;
 
  •  a controlled foreign corporation for United States tax purposes;


S-33


Table of Contents

 
  •  a foreign person 50% or more of whose gross income is effectively connected with the conduct of a United States trade or business for a specified three-year period; or
 
  •  a foreign partnership, if at any time during its tax year:
 
  •  one or more of its partners are “U.S. persons,” as defined in U.S. Treasury regulations, who in the aggregate hold more than 50% of the income or capital interest in the partnership, or
 
  •  such foreign partnership is engaged in the conduct of a United States trade or business;
 
unless the broker does not have actual knowledge or a reason to know that the holder is a United States person and the documentation requirements described above (relating to a sale of notes or debentures effected at a United States office of a broker) are met or the holder otherwise establishes an exemption.
 
Backup withholding will apply if the sale is subject to information reporting and the broker has actual knowledge or reason to know that the holder is a United States person. In general, a United States alien holder may obtain a refund of any amounts withheld under the U.S. backup withholding rules that exceed its income tax liability by filing a timely refund claim with the Internal Revenue Service.

The underwriters have agreed to purchase all of the notes and the debentures sold pursuant to the purchase agreement if any of these notes and debentures are purchased. If an underwriter defaults, the purchase agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the purchase agreement may be terminated.
 
We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.
 
The underwriters are offering the notes and the debentures, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes and the debentures, and other conditions contained in the purchase agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
 
Commissions and Discounts
 
The underwriters have advised us that they propose initially to offer the notes and the debentures to the public at the respective public offering prices on the cover page of this prospectus, and to dealers at that price less a commission not in excess of     % of the principal amount of the notes and not in excess of     % of the principal amount of the debentures. The underwriters may allow, and the dealers may reallow, a discount not in excess of     % of the principal amount of the notes and not in excess of     % of the principal amount of the debentures to other dealers. After the initial public offering, the public offering prices, concessions and discounts may be changed.

Table of Contents

The expenses of the offering, not including the underwriting discount, are estimated to be $600,000 and are payable by us.
 
New Issue of Securities
 
The notes and the debentures are new issues of securities with no established trading market. We do not intend to apply for listing of the notes or the debentures on any national securities exchange or for quotation of the notes or the debentures on any automated dealer quotation system. We have been advised by Citi and Merrill Lynch that they presently intend to make a market in the notes and debentures after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for notes or debentures or that an active public market for the notes or the debentures will develop. If an active public trading market for the notes or the debentures does not develop, the market price and liquidity of the notes or the debentures, as the case may be, may be adversely affected.
 
NASD Regulation
 
Jefferies & Company, Inc., our broker-dealer subsidiary, is a member of the NASD and will participate in the distribution of the notes and the debentures. Accordingly, the offering will be conducted in accordance with Conduct Rule 2720 of the NASD. The underwriters will not confirm sales of the notes or the debentures to any account over which they exercise discretionary authority without the prior written specific approval of the customer.
 
Price Stabilization and Short Positions
 
In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the notes and the debentures. Such transactions consist of bids or purchases to peg, fix or maintain the price of the debentures. If the underwriters create a short position in the notes or the debentures in connection with the offering, i.e., if they sell more notes or debentures than are on the cover page of this prospectus, the underwriters may reduce that short position by purchasing notes or debentures in the open market. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.
 
Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes or the debentures. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
 
Other Relationships

DESCRIPTION OF SECURITIES WE MAY OFFER
 
Debt Securities
 
Please note that in this section entitled Debt Securities, references to Jefferies, we, us, ours or our refer only to Jefferies Group, Inc. and not to its consolidated subsidiaries. Also, in this section, references to holders mean those who own debt securities registered in their own names, on the books that Jefferies or the trustee maintains for this purpose, and not those who own beneficial interests in debt securities registered in street name or in debt securities issued in book-entry form through one or more depositaries. Owners of beneficial interests in the debt securities should read the section below entitled Book-Entry Procedures and Settlement.
 
   General
 
The debt securities offered by this prospectus will be our unsecured obligations and will be either senior or subordinated debt. We will issue senior debt under a senior debt indenture, and we will issue subordinated debt under a subordinated debt indenture. We sometimes refer to the senior debt indenture and the subordinated debt indenture individually as an indenture and collectively as the indentures. The indentures have been filed with the SEC and are exhibits to the registration statement of which this prospectus forms a part. You can obtain copies of the indentures by following the directions outlined in “Where You Can Find More Information”, or by contacting the applicable indenture trustee.
 
A form of each debt security, reflecting the particular terms and provisions of a series of offered debt securities, has been filed with the SEC or will be filed with the SEC at the time of the offering as exhibits to the registration statement of which this prospectus forms a part.
 
The following briefly summarizes the material provisions of the indentures and the debt securities, other than pricing and related terms disclosed for a particular issuance in an accompanying prospectus supplement. You should read the more detailed provisions of the applicable indenture, including the defined terms, for provisions that may be important to you. You should also read the particular terms of a series of debt securities, which will be described in more detail in an accompanying prospectus supplement. So that you may easily locate the more detailed provisions, the numbers in parentheses below refer to sections in the applicable indenture or, if no indenture is specified, to sections in each of the indentures. Wherever particular sections or


2


Table of Contents

defined terms of the applicable indenture are referred to, such sections or defined terms are incorporated into this prospectus by reference, and the statement in this prospectus is qualified by that reference.
 
Unless otherwise provided for a particular issuance in an accompanying prospectus supplement, the trustee under each of the senior debt indenture and the subordinated debt indenture will be The Bank of New York.
 
The indentures provide that our unsecured senior or subordinated debt securities may be issued in one or more series, with different terms, in each case as we authorize from time to time. We also have the right to reopen a previous issue of a series of debt securities by issuing additional debt securities of such series.
 
   Types of Debt Securities
 
We may issue fixed or floating rate debt securities.
 
Fixed rate debt securities will bear interest at a fixed rate described in the prospectus supplement. This type includes zero coupon debt securities, which bear no interest and are often issued at a price lower than the principal amount. Material federal income tax consequences and other special considerations applicable to any debt securities issued at a discount will be described in the applicable prospectus supplement.
 
Upon the request of the holder of any floating rate debt security, the calculation agent will provide the interest rate then in effect for that debt security, and, if determined, the interest rate that will become effective on the next interest reset date. The calculation agent’s determination of any interest rate, and its calculation of the amount of interest for any interest period, will be final and binding in the absence of manifest error.
 
All percentages resulting from any interest rate calculation relating to a debt security will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point. All amounts used in or resulting from any calculation relating to a debt security will be rounded upward or downward, as appropriate, to the nearest cent, in the case of U.S. dollars, or to the nearest corresponding hundredth of a unit, in the case of a currency other than U.S. dollars, with one-half cent or one-half of a corresponding hundredth of a unit or more being rounded upward.
 
In determining the base rate that applies to a floating rate debt security during a particular interest period, the calculation agent may obtain rate quotes from various banks or dealers active in the relevant market, as described in the prospectus supplement. Those reference banks and dealers may include the calculation agent itself and its affiliates, as well as any underwriter, dealer or agent participating in the distribution of the relevant floating rate debt securities and its affiliates, and they may include affiliates of Jefferies.
 
   Information in the Prospectus Supplement
 
The prospectus supplement for any offered series of debt securities will describe the following terms, as applicable:
 
  •  the title;
 
  •  whether the debt is senior or subordinated;
 
  •  the total principal amount offered;
 
  •  the percentage of the principal amount at which the debt securities will be sold and, if applicable, the method of determining the price;
 
  •  the maturity date or dates;
 
  •  whether the debt securities are fixed rate debt securities or floating rate debt securities;
 
  •  if the debt securities are fixed rate debt securities, the yearly rate at which the debt security will bear interest, if any, and the interest payment dates;
 
  •  if the debt security is an original issue discount debt security, the yield to maturity;

Table of Contents

  •  if the debt securities are floating rate debt securities, the interest rate basis; any applicable index currency or maturity, spread or spread multiplier or initial, maximum or minimum rate; the interest reset, determination, calculation and payment dates; and the day count used to calculate interest payments for any period;
 
  •  the date or dates from which any interest will accrue, or how such date or dates will be determined, and the interest payment dates and any related record dates;
 
  •  if other than in U.S. Dollars, the currency or currency unit in which payment will be made;
 
  •  any provisions for the payment of additional amounts for taxes;
 
  •  the denominations in which the currency or currency unit of the securities will be issuable if other than denominations of $1,000 and integral multiples thereof;
 
  •  the terms and conditions on which the debt securities may be redeemed at the option of Jefferies;
 
  •  any obligation of Jefferies to redeem, purchase or repay the debt securities at the option of a holder upon the happening of any event and the terms and conditions of redemption, purchase or repayment;
 
  •  the names and duties of any co-trustees, depositaries, authenticating agents, calculation agents, paying agents, transfer agents or registrars for the debt securities;
 
  •  any material provisions of the applicable indenture described in this prospectus that do not apply to the debt securities; and
 
  •  any other specific terms of the debt securities.
 
The terms on which a series of debt securities may be convertible into or exchangeable for other securities of Jefferies or any other entity will be set forth in the prospectus supplement relating to such series. Such terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. The terms may include provisions pursuant to which the number of other securities to be received by the holders of such series of debt securities may be adjusted.
 
We will issue the debt securities only in registered form. As currently anticipated, debt securities of a series will trade in book-entry form, and global notes will be issued in physical (paper) form, as described below under Book-Entry Procedures and Settlement. Unless otherwise provided in the accompanying prospectus supplement, we will issue debt securities denominated in U.S. Dollars and only in denominations of $1,000 and integral multiples thereof.
 
The prospectus supplement relating to offered securities denominated in a foreign or composite currency will specify the denomination of the offered securities.
 
The debt securities may be presented for exchange, and debt securities other than a global security may be presented for registration of transfer, at the principal corporate trust office of The Bank of New York in New York City. Holders will not have to pay any service charge for any registration of transfer or exchange of debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with such registration of transfer (Section 3.05).
 
Market-Making Transactions.  If you purchase your debt security — or any of our other securities we describe in this prospectus — in a market-making transaction, you will receive information about the price you pay and your trade and settlement dates in a separate confirmation of sale. A market-making transaction is one in which Jefferies & Company, Inc. or one of our affiliates resells a security that it has previously acquired from another holder. A market-making transaction in a particular security occurs after the original issuance and sale of the security.
 
   Payment and Paying Agents
 
Distributions on the debt securities other than those represented by global notes will be made in the designated currency against surrender of the debt securities at the principal corporate trust office of The Bank

of New York in New York City. Payment will be made to the registered holder at the close of business on the record date for such payment. Interest payments will be made at the principal corporate trust office of The Bank of New York in New York City, or by a check mailed to the holder at his registered address. Payments in any other manner will be specified in the prospectus supplement.
 
   Calculation Agents
 
Calculations relating to floating rate debt securities and indexed debt securities will be made by the calculation agent, an institution that we appoint as our agent for this purpose. We may appoint one of our affiliates as calculation agent. We may appoint a different institution to serve as calculation agent from time to time after the original issue date of the debt security without your consent and without notifying you of the change. The initial calculation agent will be identified in the prospectus supplement.
 
   Senior Debt
 
We will issue senior debt securities under the senior debt indenture. Senior debt will rank on an equal basis with all our other unsecured debt except subordinated debt.
 
   Subordinated Debt
 
We will issue subordinated debt securities under the subordinated debt indenture. Subordinated debt will rank subordinated and junior in right of payment, to the extent set forth in the subordinated debt indenture, to all our senior debt.
 
If we default in the payment of any principal of, or premium, if any, or interest on any senior debt when it becomes due and payable after any applicable grace period, then, unless and until the default is cured or waived or ceases to exist, we cannot make a payment on account of or redeem or otherwise acquire the subordinated debt securities.
 
If there is any insolvency, bankruptcy, liquidation or other similar proceeding relating to us or our property, then all senior debt must be paid in full before any payment may be made to any holders of subordinated debt securities.
 
Furthermore, if we default in the payment of the principal of and accrued interest on any subordinated debt securities that is declared due and payable upon an event of default under the subordinated debt indenture, holders of all our senior debt will first be entitled to receive payment in full in cash before holders of such subordinated debt can receive any payments.
 
Senior debt means:
 
  •  the principal, premium, if any, and interest in respect of indebtedness of Jefferies for money borrowed and indebtedness evidenced by securities, notes, debentures, bonds or other similar instruments issued by us, including the senior debt securities;
 
  •  all capitalized lease obligations;
 
  •  all obligations representing the deferred purchase price of property; and
 
  •  all deferrals, renewals, extensions and refundings of obligations of the type referred to above;
 
but senior debt does not include:
 
  •  subordinated debt securities;
 
  •  any indebtedness that by its terms is subordinated to, or ranks on an equal basis with, subordinated debt securities; and
 
  •  indebtedness that is subordinated to a senior debt obligation of ours specified above.
 
The effect of this last provision is that we may not issue, assume or guarantee any indebtedness for money borrowed which is junior to the senior debt securities and senior to the subordinated debt securities.

Table of Contents

   Covenants
 
Limitations on Liens.  The senior indenture provides that we will not, and will not permit any designated subsidiary to, incur, issue, assume or guarantee any indebtedness for money borrowed if such indebtedness is secured by a pledge of, lien on\, or security interest in any shares of common stock of any designated subsidiary, without providing that each series of senior debt securities and, at our option, any other indebtedness ranking equally and ratably with such indebtedness, is secured equally and ratably with (or prior to) such other secured indebtedness (Section 10.08).
 
Limitations on Transactions with Affiliates.  The senior indenture provides that we will not, and will not permit any subsidiary to, sell, lease, transfer or otherwise dispose of any of our or its properties or assets to, or purchase any property or asset from, or enter into any transaction, contract, agreement, understanding, loan, advance or guaranty with, or for the benefit of, any affiliate of ours unless:
 
  •  the transaction with the affiliate is made on terms no less favorable to us or the subsidiary than those that would have been obtained in a comparable transaction with an unrelated person; and
 
  •  in the case of any affiliate transaction involving consideration in excess of $25 million in any fiscal year, we deliver to the trustee a certificate to the effect that our board of directors has determined that the transaction complies with the requirements described in the above bullet point and that the transaction has been approved by a majority of the disinterested members of our board of directors.
 
This covenant will not apply to any employment agreement entered into in the ordinary course of business and consistent with past practices, to any transaction between or among us and our subsidiaries or to transactions entered into prior to the date the notes are issued.
 
Limitations on Mergers and Sales of Assets.  The indentures provide that we will not merge or consolidate or transfer or lease our assets substantially as an entirety, and another person may not transfer or lease its assets substantially as an entirety to us, unless:
 
  •  either (1) we are the continuing corporation, or (2) the successor corporation, if other than us, is a U.S. corporation and expressly assumes by supplemental indenture the obligations evidenced by the securities issued pursuant to the indenture; and
 
  •  immediately after the transaction, there would not be any default in the performance of any covenant or condition of the indenture (Section 8.01).
 
Other than the restrictions described above, the indentures do not contain any covenants or provisions that would protect holders of the debt securities in the event of a highly leveraged transaction.
 
   Modification of the Indentures
 
Under the indentures, we and the relevant trustee can enter into supplemental indentures to establish the form and terms of any new series of debt securities without obtaining the consent of any holder of debt securities (Section 9.01).
 
We and the trustee may, with the consent of the holders of at least a majority in aggregate principal amount of the debt securities of a series, modify the applicable indenture or the rights of the holders of the securities of such series.
 
No such modification may, without the consent of each holder of an affected security:
 
  •  extend the fixed maturity of any such securities;
 
  •  reduce the rate or change the time of payment of interest on such securities;
 
  •  reduce the principal amount of such securities or the premium, if any, on such securities;
 
  •  change any obligation of ours to pay additional amounts;


6


Table of Contents

  •  reduce the amount of the principal payable on acceleration of any securities issued originally at a discount;
 
  •  adversely affect the right of repayment or repurchase at the option of the holder;
 
  •  reduce or postpone any sinking fund or similar provision;
 
  •  change the currency or currency unit in which any such securities are payable or the right of selection thereof;
 
  •  impair the right to sue for the enforcement of any such payment on or after the maturity of such securities;
 
  •  reduce the percentage of securities referred to above whose holders need to consent to the modification or a waiver without the consent of such holders; or
 
  •  change any obligation of ours to maintain an office or agency (Section 9.02).
 
   Defaults
 
Each indenture provides that events of default regarding any series of debt securities will be:
 
  •  our failure to pay required interest on any debt security of such series for 30 days;
 
  •  our failure to pay principal or premium, if any, on any debt security of such series when due;
 
  •  our failure to make any required scheduled installment payment for 30 days on debt securities of such series;
 
  •  our failure to perform for 90 days after notice any other covenant in the relevant indenture other than a covenant included in the relevant indenture solely for the benefit of a series of debt securities other than such series;
 
  •  our failure to pay beyond any applicable grace period, or the acceleration of, indebtedness in excess of $10,000,000; and
 
  •  certain events of bankruptcy or insolvency, whether voluntary or not (Section 5.01).
 
If an event of default regarding debt securities of any series issued under the indentures should occur and be continuing, either the trustee or the holders of 25% in the principal amount of outstanding debt securities of such series may declare each debt security of that series due and payable (Section 5.02). We are required to file annually with the trustee a statement of an officer as to the fulfillment by us of our obligations under the indenture during the preceding year (Section 10.05).
 
No event of default regarding one series of debt securities issued under an indenture is necessarily an event of default regarding any other series of debt securities.
 
Holders of a majority in principal amount of the outstanding debt securities of any series will be entitled to control certain actions of the trustee under the indentures and to waive past defaults regarding such series (Sections 5.12 and 5.13). The trustee generally cannot be required by any of the holders of debt securities to take any action, unless one or more of such holders shall have provided to the trustee reasonable security or indemnity (Section 6.02).
 
If an event of default occurs and is continuing regarding a series of debt securities, the trustee may use any sums that it holds under the relevant indenture for its own reasonable compensation and expenses incurred prior to paying the holders of debt securities of such series (Section 5.06).
 
Before any holder of any series of debt securities may institute action for any remedy, except payment on such holder’s debt security when due, the holders of not less than 25% in principal amount of the debt securities of that series outstanding must request the trustee to take action. Holders must also offer and give the satisfactory security and indemnity against liabilities incurred by the trustee for taking such action (Sections 5.07 and 5.08).

Table of Contents

   Defeasance
 
Except as may otherwise be set forth in an accompanying prospectus supplement, after we have deposited with the trustee, cash or government securities, in trust for the benefit of the holders sufficient to pay the principal of, premium, if any, and interest on the debt securities of such series when due, and satisfied certain other conditions, including receipt of an opinion of counsel that holders will not recognize taxable gain or loss for federal income tax purposes, then:
 
  •  we will be deemed to have paid and satisfied our obligations on all outstanding debt securities of such series, which is known as defeasance and discharge (Section 14.02); or
 
  •  we will cease to be under any obligation, other than to pay when due the principal of, premium, if any, and interest on such debt securities, relating to the debt securities of such series, which is known as covenant defeasance (Section 14.03).
 
When there is a defeasance and discharge, the applicable indenture will no longer govern the debt securities of such series, we will no longer be liable for payments required by the terms of the debt securities of such series and the holders of such debt securities will be entitled only to the deposited funds. When there is a covenant defeasance, however, we will continue to be obligated to make payments when due if the deposited funds are not sufficient.
 
   Payment of Additional Amounts
 
If so noted in the applicable prospectus supplement for a particular issuance, we will pay to the holder of any debt security who is a United States Alien (as defined below) such additional amounts as may be necessary so that every net payment of principal of and interest on the debt security, after deduction or withholding for or on account of any present or future tax, assessment or other governmental charge imposed upon or as a result of such payment by the United States or any taxing authority thereof or therein, will not be less than the amount provided in such debt security to be then due and payable. We will not be required, however, to make any payment of additional amounts for or on account of:
 
  •  any tax, assessment or other governmental charge that would not have been imposed but for the existence of any present or former connection between such holder (or between a fiduciary, settlor, beneficiary of, member or shareholder of, or possessor of a power over, such holder, if such holder is an estate, trust, partnership or corporation) and the United States, including, without limitation, such holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor), being or having been a citizen or resident or treated as a resident of the United States or being or having been engaged in trade or business or present in the United States or having or having had a permanent establishment in the United States;
 
  •  any tax, assessment or other governmental charge that would not have been imposed but for the presentation by the holder of the debt security for payment on a date more than 10 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;
 
  •  any estate, inheritance, gift, sales, transfer, excise, personal property or similar tax, assessment or other governmental charge;
 
  •  any tax, assessment or other governmental charge imposed by reason of such holder’s past or present status as a passive foreign investment company, a controlled foreign corporation, a personal holding company or foreign personal holding company with respect to the United States, or as a corporation which accumulates earnings to avoid United States federal income tax;

   Redemption upon a Tax Event
 
If so noted in the applicable prospectus supplement for a particular issuance, we may redeem the debt securities in whole, but not in part, on not more than 60 days’ and not less than 30 days’ notice, at a redemption price equal to 100% of their principal amount, plus all accrued but unpaid interest through the redemption date if we determine that as a result of a change in tax law (as defined below):

Prior to the publication of any notice of redemption, we shall deliver to the Trustee an officers’ certificate stating that we are entitled to effect the aforementioned redemption and setting forth a statement of facts showing that the conditions precedent to our right to so redeem have occurred, and an opinion of counsel to such effect based on such statement of facts.

   Governing Law
 
Unless otherwise stated in the prospectus supplement, the debt securities and the indentures will be governed by New York law.
 
   Concerning the Trustee under the Indentures
 
We have and may continue to have banking and other business relationships with The Bank of New York, or any subsequent trustee, in the ordinary course of business.
 
Warrants
 
Please note that in this section entitled Warrants, references to Jefferies, we, us, ours or our refer only to Jefferies Group, Inc. and not to its consolidated subsidiaries. Also, in this section, references to holders mean those who own warrants registered in their own names, on the books that Jefferies or its agent maintains for this purpose, and not those who own beneficial interests in warrants registered in street name or in warrants issued in book-entry form through one or more depositaries. Owners of beneficial interests in the warrants should read the section below entitled Book-Entry Procedures and Settlement.
 
   General
 
We may offer warrants separately or together with our debt or equity securities.
 
We may issue warrants in such amounts or in as many distinct series as we wish. This section summarizes terms of the warrants that apply generally to all series. Most of the financial and other specific terms of your warrant will be described in the prospectus supplement. Those terms may vary from the terms described here.
 
The warrants of a series will be issued under a separate warrant agreement to be entered into between us and one or more banks or trust companies, as warrant agent, as set forth in the prospectus supplement. A form of each warrant agreement, including a form of warrant certificate representing each warrant, reflecting the particular terms and provisions of a series of offered warrants, will be filed with the SEC at the time of the offering and incorporated by reference in the registration statement of which this prospectus forms a part. You can obtain a copy of any form of warrant agreement when it has been filed by following the directions outlined in “Where You Can Find More Information” or by contacting the applicable warrant agent.
 
The following briefly summarizes the material provisions of the warrant agreements and the warrants. As you read this section, please remember that the specific terms of your warrant as described in the prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this section. You should read carefully the prospectus supplement and the more detailed provisions of the warrant agreement and the warrant certificate, including the defined terms, for provisions that may be important to you. If there are differences between the prospectus supplement and this prospectus, the prospectus supplement will control. Thus, the statements made in this section may not apply to your warrant.
 
   Types of Warrants
 
We may issue debt warrants or equity warrants. A debt warrant is a warrant for the purchase of our debt securities on terms to be determined at the time of sale. An equity warrant is a warrant for the purchase or sale of our equity securities. We may also issue warrants for the purchase or sale of, or whose cash value is determined by reference to the performance, level or value of, one or more of the following: securities of one or more issuers, including those issued by us and described in this prospectus or debt or equity securities issued by third parties; a currency or currencies; a commodity or commodities; and other financial, economic

  •  the specific designation and aggregate number of, and the price at which we will issue, the warrants;
 
  •  the currency or currency unit with which the warrants may be purchased and in which any payments due to or from the holder upon exercise must be made;
 
  •  the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;
 
  •  whether the exercise price may be paid in cash, by the exchange of warrants or other securities or both, and the method of exercising the warrants;
 
  •  whether the warrants will be settled by delivery of the underlying securities or other property or in cash;
 
  •  whether and under what circumstances we may cancel the warrants prior to their expiration date, in which case the holders will be entitled to receive only the applicable cancellation amount, which may be either a fixed amount or an amount that varies during the term of the warrants in accordance with a schedule or formula;
 
  •  whether the warrants will be issued in global or non-global form, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any debt security or purchase contract included in that unit;
 
  •  the identities of the warrant agent, any depositaries and any paying, transfer, calculation or other agents for the warrants;
 
  •  any securities exchange or quotation system on which the warrants or any securities deliverable upon exercise of the warrants may be listed;
 
  •  whether the warrants are to be sold separately or with other securities, as part of units or otherwise, and if the warrants are to be sold with the securities of another company or other companies, certain information regarding such company or companies; and
 
  •  any other terms of the warrants.
 
If warrants are issued as part of a unit, the prospectus supplement will specify whether the warrants will be separable from the other securities in the unit before the warrants’ expiration date.
 
No holder of a warrant will, as such, have any rights of a holder of the debt securities, equity securities or other warrant property purchasable under or in the warrant, including any right to receive payment thereunder.
 
Our affiliates may resell our warrants in market-making transactions after their initial issuance. We discuss these transactions above under “Debt Securities — Information in the Prospectus Supplement — Market-Making Transactions.”
 
   Additional Information in the Prospectus Supplement for Debt Warrants
 
In the case of debt warrants, the prospectus supplement will contain, where appropriate, the following additional information:
 
  •  the designation, aggregate principal amount, currency and terms of the debt securities that may be purchased upon exercise of the debt warrants; and


11


Table of Contents

  •  the designation, terms and amount of debt securities, if any, to be issued together with each of the debt warrants and the date, if any, after which the debt warrants and debt securities will be separately transferable.
 
   No Limit on Issuance of Warrants
 
The warrant agreements will not limit the number of warrants or other securities that we may issue.
 
   Modifications
 
We and the relevant warrant agent may, without the consent of the holders, amend each warrant agreement and the terms of each issue of warrants, for the purpose of curing any ambiguity or of correcting or supplementing any defective or inconsistent provision, or in any other manner that we may deem necessary or desirable and that will not adversely affect the interests of the holders of the outstanding unexercised warrants in any material respect.
 
We and the relevant warrant agent also may, with the consent of the holders of at least a majority in number of the outstanding unexercised warrants affected, modify or amend the warrant agreement and the terms of the warrants.
 
No such modification or amendment may, without the consent of each holder of an affected warrant:
 
  •  reduce the amount receivable upon exercise, cancellation or expiration;
 
  •  shorten the period of time during which the warrants may be exercised;
 
  •  otherwise materially and adversely affect the exercise rights of the beneficial owners of the warrants; or
 
  •  reduce the percentage of outstanding warrants whose holders must consent to modification or amendment of the applicable warrant agreement or the terms of the warrants.
 
   Merger and Similar Transactions Permitted; No Restrictive Covenants or Events of Default
 
The warrant agreements will not restrict our ability to merge or consolidate with, or sell our assets to, another firm or to engage in any other transactions. If at any time there is a merger or consolidation involving us or a sale or other disposition of all or substantially all of our assets, the successor or assuming company will be substituted for us, with the same effect as if it had been named in the warrant agreement and in the warrants. We will be relieved of any further obligation under the warrant agreement or warrants, and, in the event of any such merger, consolidation, sale or other disposition, we as the predecessor corporation may at any time thereafter be dissolved, wound up or liquidated.
 
The warrant agreements will not include any restrictions on our ability to put liens on our assets, including our interests in our subsidiaries, nor will they provide for any events of default or remedies upon the occurrence of any events of default.
 
   Warrant Agreements Will Not Be Qualified under Trust Indenture Act
 
No warrant agreement will be qualified as an indenture, and no warrant agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of warrants issued under a warrant agreement will not have the protection of the Trust Indenture Act with respect to their warrants.
 
   Enforceability of Rights by Beneficial Owner
 
Each warrant agent will act solely as our agent in connection with the issuance and exercise of the applicable warrants and will not assume any obligation or relationship of agency or trust for or with any registered holder of or owner of a beneficial interest in any warrant. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant certificate, including any duty or responsibility to initiate any proceedings at law or otherwise or to make any demand upon us.

Holders may, without the consent of the applicable warrant agent, enforce by appropriate legal action, on their own behalf, their right to exercise their warrants, to receive debt securities, in the case of debt warrants, and to receive payment, if any, for their warrants, in the case of universal warrants.
 
   Governing Law
 
Unless otherwise stated in the prospectus supplement, the warrants and each warrant agreement will be governed by New York law.
 
Preferred Stock
 
As of the date of this prospectus, our authorized capital stock includes 10 million shares of preferred stock, none of which has been issued as of December 14, 2005. The following briefly summarizes the material terms of our preferred stock, other than pricing and related terms disclosed for a particular issuance in an accompanying prospectus supplement. You should read the particular terms of any series of preferred stock we offer which will be described in more detail in the prospectus supplement prepared for such series, together with the more detailed provisions of our certificate of incorporation and the certificate of designations relating to each particular series of preferred stock, for provisions that may be important to you. The certificate of designations relating to a particular series of preferred stock offered by way of an accompanying prospectus supplement will be filed with the SEC at the time of the offering and incorporated by reference in the registration statement of which this prospectus forms a part. You can obtain a copy of this document by following the directions outlined in “Where You Can Find More Information.” The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered.
 
   General
 
Under our certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series, and to establish from time to time a series of preferred stock with the following terms specified:
 
  •  the number of shares to be included in the series;
 
  •  the designation, powers, preferences and rights of the shares of the series; and
 
  •  the qualifications, limitations or restrictions of such series, except as otherwise stated in the certificate of incorporation.
 
Prior to the issuance of any series of preferred stock, our board of directors will adopt resolutions creating and designating the series as a series of preferred stock and the resolutions will be filed in a certificate of designations as an amendment to the certificate of incorporation. The term board of directors includes any duly authorized committee.
 
The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future, provided that the future issuances are first approved by the holders of the class(es) of preferred stock adversely affected. The board of directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose. Examples of proper corporate purposes include issuances to obtain additional financing in connection with acquisitions or otherwise, and issuances to our officers, directors and employees pursuant to benefit plans or otherwise. Shares of preferred stock we issue may have the effect of rendering more difficult or discouraging an acquisition of us deemed undesirable by our board of directors.
 
The preferred stock will be, when issued, fully paid and nonassessable. Holders of preferred stock will not have any preemptive or subscription rights to acquire more of our stock.
 
We will name the transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock in the prospectus supplement relating to such series.

Our affiliates may resell our preferred stock in market-marking transactions after its initial issuance. We discuss these transactions above under “Debt Securities — Information in the Prospectus Supplement — Market-Making Transactions.”
 
   Rank
 
Unless otherwise specified for a particular series of preferred stock in an accompanying prospectus supplement, each series will rank on an equal basis with each other series of preferred stock, and prior to the common stock, as to dividends and distributions of assets.
 
   Dividends
 
Holders of each series of preferred stock will be entitled to receive cash dividends, when, as and if declared by our board of directors out of funds legally available for dividends. The rates and dates of payment of dividends will be set forth in the prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on our books or, if applicable, the records of the depositary referred to below under Depositary Shares, on the record dates fixed by the board of directors. Dividends on any series of preferred stock may be cumulative or noncumulative.
 
We may not declare, pay or set apart for payment dividends on the preferred stock unless full dividends on any other series of preferred stock that ranks on an equal or senior basis have been paid or sufficient funds have been set apart for payment for:
 
  •  all prior dividend periods of the other series of preferred stock that pay dividends on a cumulative basis; or
 
  •  the immediately preceding dividend period of the other series of preferred stock that pay dividends on a noncumulative basis.
 
Partial dividends declared on shares of preferred stock and any other series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for both series of preferred stock.
 
Similarly, we may not declare, pay or set apart for payment non-stock dividends or make other payments on the common stock or any other of our stock ranking junior to the preferred stock until full dividends on the preferred stock have been paid or set apart for payment for:
 
  •  all prior dividend periods if the preferred stock pays dividends on a cumulative basis; or
 
  •  the immediately preceding dividend period if the preferred stock pays dividends on a noncumulative basis.
 
   Conversion and Exchange
 
The prospectus supplement for any series of preferred stock will state the terms, if any, on which shares of that series are convertible into or exchangeable for shares of our common stock.
 
   Redemption
 
If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or at the option of the holder thereof and may be mandatorily redeemed.
 
Any partial redemptions of preferred stock will be made in a way that our board of directors decides is equitable.
 
Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.

Table of Contents

   Liquidation Preference
 
Upon our voluntary or involuntary liquidation, dissolution or winding up, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount set forth in the prospectus supplement relating to such series of preferred stock, plus an amount equal to any accrued and unpaid dividends. Such distributions will be made before any distribution is made on any securities ranking junior relating to preferred stock in liquidation, including common stock.
 
If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of such series and such other securities will share in any such distribution of our available assets on a ratable basis in proportion to the full liquidation preferences. Holders of such series of preferred stock will not be entitled to any other amounts from us after they have received their full liquidation preference.
 
   Voting Rights
 
The holders of shares of our preferred stock will have no voting rights, except:
 
  •  as otherwise stated in the prospectus supplement;
 
  •  as otherwise stated in the certificate of designations establishing such series; and
 
  •  as required by applicable law.
 
Depositary Shares
 
The following briefly summarizes the material provisions of the deposit agreement and of the depositary shares and depositary receipts, other than pricing and related terms disclosed for a particular issuance in an accompanying prospectus supplement. You should read the particular terms of any depositary shares and any depositary receipts that we offer and any deposit agreement relating to a particular series of preferred stock which will be described in more detail in a prospectus supplement. The prospectus supplement will also state whether any of the generalized provisions summarized below do not apply to the depositary shares or depositary receipts being offered. A copy of the form of deposit agreement, including the form of depositary receipt, is an exhibit to the registration statement of which this prospectus forms a part. You can obtain copies of these documents by following the directions outlined in “Where You Can Find More Information.” You should read the more detailed provisions of the deposit agreement and the form of depositary receipt for provisions that may be important to you.
 
   General
 
We may, at our option, elect to offer fractional shares of preferred stock, rather than full shares of preferred stock. In such event, we will issue receipts for depositary shares, each of which will represent a fraction of a share of a particular series of preferred stock.
 
We will deposit the shares of any series of preferred stock represented by depositary shares under a deposit agreement between us and a bank or trust company selected by us having its principal office in the United States and having a combined capital and surplus of at least $50,000,000, as preferred stock depositary. Each owner of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock, including dividend, voting, redemption, conversion and liquidation rights, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share.
 
The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of preferred stock in accordance with the terms of the applicable prospectus supplement.
 
Our affiliates may resell depositary shares in market-marking transactions after their initial issuance. We discuss these transactions above under “Debt Securities — Information in the Prospectus Supplement — Market-Making Transactions.”

Table of Contents

   Dividends and Other Distributions
 
The preferred stock depositary will distribute all cash dividends or other cash distributions received in respect of the deposited preferred stock to the record holders of depositary shares relating to such preferred stock in proportion to the number of such depositary shares owned by such holders.
 
The preferred stock depositary will distribute any property other than cash received by it in respect of the preferred stock to the record holders of depositary shares entitled thereto. If the preferred stock depositary determines that it is not feasible to make such distribution, it may, with our approval, sell such property and distribute the net proceeds from such sale to such holders.
 
   Redemption of Preferred Stock
 
If a series of preferred stock represented by depositary shares is to be redeemed, the depositary shares will be redeemed from the proceeds received by the preferred stock depositary resulting from the redemption, in whole or in part, of such series of preferred stock. The depositary shares will be redeemed by the preferred stock depositary at a price per depositary share equal to the applicable fraction of the redemption price per share payable in respect of the shares of preferred stock so redeemed.
 
Whenever we redeem shares of preferred stock held by the preferred stock depositary, the preferred stock depositary will redeem as of the same date the number of depositary shares representing shares of preferred stock so redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by the preferred stock depositary by lot or ratably or by any other equitable method as the preferred stock depositary may decide.
 
   Voting Deposited Preferred Stock
 
Upon receipt of notice of any meeting at which the holders of any series of deposited preferred stock are entitled to vote, the preferred stock depositary will mail the information contained in such notice of meeting to the record holders of the depositary shares relating to such series of preferred stock. Each record holder of such depositary shares on the record date will be entitled to instruct the preferred stock depositary to vote the amount of the preferred stock represented by such holder’s depositary shares. The preferred stock depositary will try to vote the amount of such series of preferred stock represented by such depositary shares in accordance with such instructions.
 
We will agree to take all actions that the preferred stock depositary determines as necessary to enable the preferred stock depositary to vote as instructed. The preferred stock depositary will abstain from voting shares of any series of preferred stock held by it for which it does not receive specific instructions from the holders of depositary shares representing such shares.
 
   Amendment and Termination of the Deposit Agreement
 
The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may at any time be amended by agreement between us and the preferred stock depositary. However, any amendment that materially and adversely alters any existing right of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of such depositary shares then outstanding. Every holder of an outstanding depositary receipt at the time any such amendment becomes effective shall be deemed, by continuing to hold such depositary receipt, to consent and agree to such amendment and to be bound by the deposit agreement, which has been amended thereby. The deposit agreement may be terminated only if:
 
  •  all outstanding depositary shares have been redeemed; or
 
  •  a final distribution in respect of the preferred stock has been made to the holders of depositary shares in connection with our liquidation, dissolution or winding up.

   Charges of Preferred Stock Depositary; Taxes and Other Governmental Charges
 
We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We also will pay charges of the depositary in connection with the initial deposit of preferred stock and any redemption of preferred stock. Holders of depositary receipts will pay other transfer and other taxes and governmental charges and such other charges, including a fee for the withdrawal of shares of preferred stock upon surrender of depositary receipts, as are expressly provided in the deposit agreement to be for their accounts.
 
   Resignation and Removal of Depositary
 
The preferred stock depositary may resign at any time by delivering to us notice of its intent to do so, and we may at any time remove the preferred stock depositary, any such resignation or removal to take effect upon the appointment of a successor preferred stock depositary and its acceptance of such appointment. Such successor preferred stock depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.
 
   Miscellaneous
 
The preferred stock depositary will forward all reports and communications from us which are delivered to the preferred stock depositary and which we are required to furnish to the holders of the deposited preferred stock.
 
Neither we nor the preferred stock depositary will be liable if either is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement. Our obligations and those of the preferred stock depositary under the deposit agreement will be limited to performance in good faith of their duties thereunder and they will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares, depositary receipts or shares of preferred stock unless satisfactory indemnity is furnished. We and the preferred stock depositary may rely upon written advice of counsel or accountants, or upon information provided by holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine.
 
Purchase Contracts
 
We may issue purchase contracts for the purchase or sale of:
 
  •  debt or equity securities issued by us or securities of third parties, a basket of such securities, an index or indices of such securities or any combination of the foregoing as specified in the applicable prospectus supplement;
 
  •  currencies; or
 
  •  commodities.
 
Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.
 
The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders


17


Table of Contents

thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under either the senior indenture or the subordinated indenture.
 
Units
 
As specified in the applicable prospectus supplement, we may issue units consisting of one or more purchase contracts, warrants, debt securities, depositary shares, preferred shares, common shares or any combination of such securities. The applicable prospectus supplement will describe:
 
  •  the terms of the units and of the purchase contracts, warrants, debt securities, depositary shares, preferred shares and common shares comprising the units, including whether and under what circumstances the securities comprising the units may be traded separately;
 
  •  a description of the terms of any unit agreement governing the units; and
 
  •  a description of the provisions for the payment, settlement, transfer or exchange or the units.
 
Common Stock
 
Our authorized capital stock includes 500 million shares of common stock, 58,113,256 of which were issued and outstanding as of December 13, 2005. The following briefly summarizes the material terms of our common stock. You should read the more detailed provisions of our certificate of incorporation and by-laws for provisions that may be important to you. You can obtain copies of these documents by following the directions outlined in “Where You Can Find More Information.”
 
   General
 
Each holder of common stock is entitled to one vote per share for the election of directors and for all other matters to be voted on by stockholders. Except as otherwise provided by law, the holders of common stock vote as one class together with holders of our preferred stock (if they have voting rights), none of which was outstanding as of December 14, 2005. Holders of common stock may not cumulate their votes in the election of directors, and are entitled to share equally in the dividends that may be declared by the board of directors, but only after payment of dividends required to be paid on outstanding shares of preferred stock.
 
Upon our voluntary or involuntary liquidation, dissolution or winding up, holders of common stock share ratably in the assets remaining after payments to creditors and provision for the preference of any preferred stock. There are no preemptive or other subscription rights, conversion rights or redemption or scheduled installment payment provisions relating to shares of our common stock. All of the outstanding shares of our common stock are fully paid and nonassessable. The transfer agent and registrar for the common stock is American Stock Transfer. The common stock is listed on the New York Stock Exchange under the symbol “JEF.”
 
Our affiliates may resell our common stock after its initial issuance in market-making transactions. We discuss these transactions above under “Debt Securities — Information in the Prospectus Supplement — Market-Making Transactions.”
 
   Delaware Law, Certificate of Incorporation and By-Law Provisions that May Have an Antitakeover Effect
 
The following discussion concerns certain provisions of Delaware law and our certificate of incorporation and by-laws that may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interest, including offers or attempts that might result in a premium being paid over the market price for its shares.

  •  prior to the business combination the corporation’s board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; or
 
  •  upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the stockholder owned at least 85% of the outstanding voting stock of the corporation at the time the transaction commenced, excluding for the purpose of determining the number of shares outstanding those shares owned by the corporation’s officers and directors and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
 
  •  at or subsequent to the time the business combination is approved by the corporation’s board of directors and authorized at an annual or special meeting of its stockholders, and not by written consent, by the affirmative vote of at least 662/3% of its outstanding voting stock which is not owned by the interested stockholder.
 
A business combination includes mergers, asset sales or other transactions resulting in a financial benefit to the stockholder. An interested stockholder is a person who, together with affiliates and associates, owns (or within three years did own) 15% or more of the corporation’s voting stock.
 
Certificate of Incorporation and By-Laws.  Our by-laws provide that special meetings of stockholders may be called by our Secretary only at the request of a majority of our board of directors or by any person authorized by the board of directors to call a special meeting. Written notice of a special meeting stating the place, date and hour of the meeting and the purposes for which the meeting is called must be given between 10 and 60 days before the date of the meeting, and only business specified in the notice may come before the meeting. In addition, our by-laws provide that directors be elected by a plurality of votes cast at an annual meeting and does not include a provision for cumulative voting for directors. Under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors.
 
FORM, EXCHANGE AND TRANSFER
 
We will issue securities only in registered form; no securities will be issued in bearer form. We will issue each security other than common stock in book-entry form only, unless otherwise specified in the applicable prospectus supplement. We will issue common stock in both certificated and book-entry form, unless otherwise specified in the applicable prospectus supplement. Securities in book-entry form will be represented by a global security registered in the name of a depositary, which will be the holder of all the securities represented by the global security. Those who own beneficial interests in a global security will do so through participants in the depositary’s system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. Only the depositary will be entitled to transfer or exchange a security in global form, since it will be the sole holder of the security. These book-entry securities are described below under Book-Entry Procedures and Settlement.
 
If any securities are issued in non-global form or cease to be book-entry securities (in the circumstances described in the next section), the following will apply to them:
 
  •  The securities will be issued in fully registered form in denominations stated in the prospectus supplement. You may exchange securities for securities of the same series in smaller denominations or combined into fewer securities of the same series of larger denominations, as long as the total amount is not changed.
 
  •  You may exchange, transfer, present for payment or exercise securities at the office of the relevant trustee or agent indicated in the prospectus supplement. You may also replace lost, stolen, destroyed or mutilated securities at that office. We may appoint another entity to perform these functions or may perform them itself.

  •  You will not be required to pay a service charge to transfer or exchange their securities, but they may be required to pay any tax or other governmental charge associated with the transfer or exchange. The transfer or exchange, and any replacement, will be made only if our transfer agent is satisfied with your proof of legal ownership. The transfer agent may also require an indemnity before replacing any securities.
 
  •  If we have the right to redeem, accelerate or settle any securities before their maturity or expiration, and we exercise that right as to less than all those securities, we may block the transfer or exchange of those securities during the period beginning 15 days before the day we mail the notice of exercise and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers of or exchange any security selected for early settlement, except that we will continue to permit transfers and exchanges of the unsettled portion of any security being partially settled.
 
  •  If fewer than all of the securities represented by a certificate that are payable or exercisable in part are presented for payment or exercise, a new certificate will be issued for the remaining amount of securities.
 
BOOK-ENTRY PROCEDURES AND SETTLEMENT
 
Most offered securities will be book-entry (global) securities. Upon issuance, all book-entry securities will be represented by one or more fully registered global securities, without coupons. Each global security will be deposited with, or on behalf of, The Depository Trust Company or DTC, a securities depository, and will be registered in the name of DTC or a nominee of DTC. DTC will thus be the only registered holder of these securities.
 
Purchasers of securities may only hold interests in the global notes through DTC if they are participants in the DTC system. Purchasers may also hold interests through a securities intermediary — banks, brokerage houses and other institutions that maintain securities accounts for customers — that has an account with DTC or its nominee. DTC will maintain accounts showing the security holdings of its participants, and these participants will in turn maintain accounts showing the security holdings of their customers. Some of these customers may themselves be securities intermediaries holding securities for their customers. Thus, each beneficial owner of a book-entry security will hold that security indirectly through a hierarchy of intermediaries, with DTC at the top and the beneficial owner’s own securities intermediary at the bottom.
 
The securities of each beneficial owner of a book-entry security will be evidenced solely by entries on the books of the beneficial owner’s securities intermediary. The actual purchaser of the securities will generally not be entitled to have the securities represented by the global securities registered in its name and will not be considered the owner under the declaration. In most cases, a beneficial owner will also not be able to obtain a paper certificate evidencing the holder’s ownership of securities. The book-entry system for holding securities eliminates the need for physical movement of certificates and is the system through which most publicly traded common stock is held in the United States. However, the laws of some jurisdictions require some purchasers of securities to take physical delivery of their securities in definitive form. These laws may impair the ability to transfer book-entry securities.
 
A beneficial owner of book-entry securities represented by a global security may exchange the securities for definitive (paper) securities only if:
 
  •  DTC is unwilling or unable to continue as depositary for such global security and we do not appoint a qualified replacement for DTC within 90 days; or
 
  •  we in our sole discretion decide to allow some or all book-entry securities to be exchangeable for definitive securities in registered form.
 
Unless we indicate otherwise, any global security that is exchangeable will be exchangeable in whole for definitive securities in registered form, with the same terms and of an equal aggregate principal amount. Definitive securities will be registered in the name or names of the person or persons specified by DTC in a


20


Table of Contents

written instruction to the registrar of the securities. DTC may base its written instruction upon directions that it receives from its participants.
 
In this prospectus, for book-entry securities, references to actions taken by security holders will mean actions taken by DTC upon instructions from its participants, and references to payments and notices of redemption to security holders will mean payments and notices of redemption to DTC as the registered holder of the securities for distribution to participants in accordance with DTC’s procedures.
 
DTC is a limited purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a clearing corporation within the meaning of the New York Uniform Commercial Code and a clearing agency registered under section 17A of the Securities Exchange Act of 1934. The rules applicable to DTC and its participants are on file with the SEC.
 
We will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interest in the book-entry securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.
 
Clearstream and Euroclear
 
Links have been established among DTC, Clearstream Banking, societe anonyme, Luxembourg (Clearstream Banking SA) and Euroclear (two international clearing systems that perform functions similar to those that DTC performs in the U.S.), to facilitate the initial issuance of book-entry securities and cross-market transfers of book-entry securities associated with secondary market trading.
 
Although DTC, Clearstream Banking SA and Euroclear have agreed to the procedures provided below in order to facilitate transfers, they are under no obligation to perform such procedures, and the procedures may be modified or discontinued at any time.
 
Clearstream Banking SA and Euroclear will record the ownership interests of their participants in much the same way as DTC, and DTC will record the aggregate ownership of each of the U.S. agents of Clearstream Banking SA and Euroclear, as participants in DTC.
 
When book-entry securities are to be transferred from the account of a DTC participant to the account of a Clearstream Banking SA participant or a Euroclear participant, the purchaser must send instructions to Clearstream Banking SA or Euroclear through a participant at least one business day prior to settlement. Clearstream Banking SA or Euroclear, as the case may be, will instruct its U.S. agent to receive book-entry securities against payment. After settlement, Clearstream Banking SA or Euroclear will credit its participant’s account. Credit for the book-entry securities will appear on the next day (European time).
 
Because settlement is taking place during New York business hours, DTC participants can employ their usual procedures for sending book-entry securities to the relevant U.S. agent acting for the benefit of Clearstream Banking SA or Euroclear participants. The sale proceeds will be available to the DTC seller on the settlement date. Thus, to the DTC participant, a cross-market transaction will settle no differently than a trade between two DTC participants.
 
When a Clearstream Banking SA or Euroclear participant wishes to transfer book-entry securities to a DTC participant, the seller must send instructions to Clearstream Banking SA or Euroclear through a participant at least one business day prior to settlement. In these cases, Clearstream Banking SA or Euroclear will instruct its U.S. agent to transfer the book-entry securities against payment. The payment will then be reflected in the account of the Clearstream Banking SA or Euroclear participant the following day, with the proceeds back-valued to the value date (which would be the preceding day, when settlement occurs in New York). If settlement is not completed on the intended value date (i.e., the trade fails), proceeds credited to the Clearstream Banking SA or Euroclear participant’s account would instead be valued as of the actual settlement date.

CERTAIN ERISA CONSIDERATIONS
 
Jefferies Group, Inc. has certain affiliates that provide services to many employee benefit plans. Jefferies Group, Inc. and certain of its affiliates may each be considered a party in interest within the meaning of the Employee Retirement Income Security Act of 1974 (ERISA), or a disqualified person under corresponding provisions of the Internal Revenue Code of 1986 (the Code), relating to many employee benefit plans. Prohibited transactions within the meaning of ERISA and the Code may result if any offered securities are acquired by or with the assets of a pension or other employee benefit plan relating to which Jefferies Group, Inc. or any of its affiliates is a service provider, unless those securities are acquired under an exemption for transactions effected on behalf of that plan by a “qualified professional asset manager” or an “in-house asset manager” or under any other available exemption. Additional special considerations may arise in connection with the acquisition of capital securities by or with the assets of a pension or other employee benefit plan. The assets of a pension or other employee benefit plan may include assets held in the general account of an insurance company that are deemed to be “plan assets” under ERISA. Any employee benefit plan or other entity subject to such provisions of ERISA or the Code proposing to acquire the offered securities should consult with its legal counsel.
