Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Jefferies Financial Group Inc. ("Jefferies" or the "Company") is a diversified financial services company engaged in investment banking and capital markets, asset management and direct investing. Jefferies Group LLC ("Jefferies Group"), our largest subsidiary, is the largest independent full-service global investment banking firm headquartered in the U.S. Jefferies Group operates in two business segments: Capital Markets and Asset Management. Capital Markets includes investment banking, sales and trading and other related services. Investment banking provides capital markets and financial advisory services to clients across most industry sectors in the Americas, Europe and Asia. Sales and trading businesses operate across the spectrum of equities, fixed income and foreign exchange products. Related services include, among other things, prime brokerage and equity finance, research and strategy, corporate lending and real estate finance, as well as other principal and corporate investing activities. Asset Management provides investment management services to investors in the U.S. and overseas and makes capital investments in managed funds and accounts. In March 2013, Jefferies Group became an indirect wholly-owned subsidiary of Jefferies, yet retains a separate credit rating and continues to be a separate U.S. Securities and Exchange Commission ("SEC") reporting company. Merchant Banking is where we invest in unique long-term opportunities. Our current Merchant Banking businesses and investments include National Beef Packing Company, LLC ("National Beef") (beef processing), Spectrum Brands Holdings, Inc. ("Spectrum Brands") (consumer products), Linkem (fixed wireless broadband services in Italy), Vitesse Energy, LLC ("Vitesse Energy Finance") and JETX Energy, LLC ("JETX Energy") (oil and gas production and development), WeWork (global network of workspaces), HomeFed Corporation ("HomeFed") (real estate), Idaho Timber (manufacturing) and FXCM Group, LLC ("FXCM") (provider of online foreign exchange trading services). Our Merchant Banking businesses and investments also included Leucadia Asset Management ("LAM") (asset management) and Berkadia Commercial Mortgage Holding LLC ("Berkadia") (commercial mortgage banking, investment sales and servicing), prior to their transfer to Jefferies Group in the fourth quarter of 2018 and Garcadia (automobile dealerships), prior to its sale in August 2018. The structure of each of our investments was tailored to the unique opportunity each transaction presented. Our investments may be reflected in our consolidated results as consolidated subsidiaries, equity investments, securities or in other ways, depending on the structure of our specific holdings. We now own 31% of National Beef, one of the largest beef processing companies in the U.S. On June 5, 2018, we completed the sale of 48% of National Beef to Marfrig Global Foods S.A. ("Marfrig") reducing our ownership in National Beef from 79% to 31% . As of the closing of the sale on June 5, 2018, we deconsolidated our investment in National Beef and account for our remaining 31% interest in National Beef under the equity method of accounting. We classified the results of National Beef prior to June 5, 2018 as discontinued operations in the Consolidated Statements of Operations. See Note 24 for more information. We own approximately 15% of Spectrum Brands, a publicly traded global consumer products company on the NYSE (NYSE: SPB), and we reflect this investment at fair value based on quoted market prices. We own approximately 42% of the common shares of Linkem, as well as convertible preferred shares which, if converted, would increase our ownership to approximately 54% of Linkem's common equity at February 28, 2019 . Linkem provides residential broadband services in Italy using LTE technologies deployed over the 3.5 GHz spectrum band. Linkem is accounted for under the equity method. Vitesse Energy Finance is our 97% owned consolidated subsidiary that acquires and invests in non-operated working interests and royalties predominantly in the Bakken Shale oil field in North Dakota. JETX Energy is our 98% owned consolidated subsidiary that currently has non-operated working interests and acreage in east Texas. We invested $9.0 million in 2013 in WeWork, which creates collaborative office communities. Currently we own less than 1% of the company. Our interest in WeWork is reflected in Trading assets in our financial statements at fair value. We own an approximate 70% equity interest of HomeFed, which owns and develops residential and mixed use real estate properties. We account for our interest under the equity method. HomeFed is a public company traded on the Over-the-Counter Bulletin Board. During the first quarter of 2019, we proposed to acquire the remaining common stock of HomeFed (the "Proposed Transaction"). The Proposed Transaction would entail issuing two shares of our common stock for each share of HomeFed’s common stock. The proposal includes a condition that the Proposed Transaction will require the approval of a majority of the outstanding shares of HomeFed’s common stock not already owned by us (or our affiliates), in addition to approval of HomeFed's board of directors upon the recommendation of a special committee of independent directors and any other vote required by applicable law. As an offset to these potentially issued shares, our Board of Directors has, conditioned on the closing of the Proposed Transaction, authorized the repurchase of these shares in the open market. This share-repurchase approval is incremental to the $500.0 million share repurchase previously approved by our Board of Directors, approximately $305.3 million of which remains to be purchased as of February 28, 2019 . The Proposed Transaction is currently being evaluated by a special committee of independent directors of HomeFed. Idaho Timber is our consolidated subsidiary engaged in the manufacture and distribution of various wood products. Our investment in FXCM and associated companies consists of a senior secured term loan due in the second quarter of 2019, ( $71.4 million principal outstanding at February 28, 2019 ); a 50% voting interest in FXCM and the right to receive up to 75% of all distributions in respect of the equity of FXCM.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Our unaudited interim consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes which are normally included in our Form 10-K. These financial statements reflect all adjustments (consisting of normal recurring items or items discussed herein) that management believes are necessary to fairly state results for the interim periods presented. Results of operations for interim periods are not necessarily indicative of annual results of operations. For a detailed discussion about the Company’s significant accounting policies, see Note 2, Significant Accounting Policies, included in our Transition Report on Form 10-K for the year ended November 30, 2018 ("2018 10-K"). The preparation of these financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") requires us to make estimates and assumptions that affect the reported amounts in the financial statements and disclosures of contingent assets and liabilities. On an on-going basis, we evaluate all of these estimates and assumptions. The most important of these estimates and assumptions relate to fair value measurements, compensation and benefits, asset impairment, the ability to realize deferred tax assets, the recognition and measurement of uncertain tax positions and contingencies. Although these and other estimates and assumptions are based on the best available information, actual results could be different from these estimates. In the fourth quarter of 2018, we changed our fiscal year end from a calendar year basis to a fiscal year ending on November 30, consistent with the fiscal year of Jefferies Group. Jefferies Group has a November 30 year-end, which it retains for standalone reporting purposes. Prior to the fourth quarter of 2018, because our fiscal year end was December 31, we reflected Jefferies Group in our consolidated financial statements utilizing a one month lag. In connection with our change in fiscal year end to November 30, we eliminated the one month lag utilized to reflect Jefferies Group results beginning with the fourth quarter of 2018. Receivables At February 28, 2019 and November 30, 2018 , Receivables include receivables from brokers, dealers and clearing organizations of $4,537.2 million and $3,223.7 million , respectively, and receivables from customers of securities operations of $1,597.0 million and $2,017.1 million , respectively. Our subsidiary, Foursight Capital, had auto loan receivables of $668.6 million and $648.7 million at February 28, 2019 and November 30, 2018 , respectively. Based primarily on Beacon credit scores, Foursight Capital classifies its auto loan receivables as prime, near-prime and sub-prime based on the perceived credit risk at origination and generally considers prime receivables as those with a Beacon score of 680 and above, near-prime with scores of 620 and 679 and sub-prime with scores below 620. The credit quality classification at February 28, 2019 and November 30, 2018 was approximately 14% and 13% prime, 57% and 57% near-prime and 29% and 30% sub-prime, respectively. Payables, expense accruals and other liabilities At February 28, 2019 and November 30, 2018 , Payables, expense accruals and other liabilities include payables to brokers, dealers and clearing organizations of $2,767.6 million and $2,465.6 million , respectively, and payables to customers of securities operations of $3,389.6 million and $3,176.7 million , respectively. Supplemental Cash Flow Information For the Three Months Ended February 28, 2019 March 31, 2018 (In thousands) Cash paid during the year for: Interest $ 399,350 $ 322,769 Income tax payments (refunds), net $ 7,205 $ (1,918 ) Accounting Developments - Accounting Standards to be Adopted in Future Periods Leases. In February 2016, the Financial Accounting Standards Board ("FASB") issued new guidance that affects the accounting and disclosure requirements for leases. The FASB requires the recognition of all leases that are longer than one year onto the balance sheet, which will result in the recognition of a right of use asset and a corresponding lease liability. The right of use asset and lease liability will be measured initially using the present value of the remaining rental payments. A significant portion of the population of contracts that will be subject to recognition on our Consolidated Statements of Financial Condition have been identified; however, their initial measurement still remains under evaluation. We are currently modifying certain of our lease accounting systems to enable us to comply with the accounting requirements of this guidance. In July 2018, the FASB issued additional guidance on leases which allows an entity to recognize a cumulative-effect adjustment to the opening balance of retained earnings upon adoption. The guidance is effective for annual and interim periods beginning after December 15, 2018. We plan on adopting the lease standard in the first quarter of fiscal 2020 with a cumulative-effect adjustment to opening retained earnings in the period of adoption. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Financial Instruments - Credit Losses. In June 2016, the FASB issued new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. The guidance is effective in the first quarter of fiscal 2021. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Goodwill. In January 2017, the FASB issued new guidance for simplifying goodwill impairment testing. The guidance is effective in the first quarter of fiscal 2021. We do not believe the new guidance will have a material impact on our consolidated financial statements. Derivatives and Hedging. In August 2017, the FASB issued new guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The guidance is effective in the first quarter of fiscal 2020. We do not believe the new guidance will have a material impact on our consolidated financial statements. Defined Benefit Plans. In August 2018, the FASB issued new guidance to improve the effectiveness of disclosure requirements on defined benefit pension plans and other post-retirement plans. The guidance is effective in the first quarter of fiscal 2021. We do not believe the new guidance will have a material impact on our consolidated financial statements. Internal-Use Software. In August 2018, the FASB issued new guidance which amends the definition of a hosting arrangement and requires that the customer in a hosting arrangement that is a service contract capitalize certain implementation costs as if the arrangement was an internal-use software project. The guidance is effective in the first quarter of fiscal 2021. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Consolidation. In October 2018, the FASB issued new guidance which requires indirect interests held through related parties under common control arrangements be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. The guidance is effective in the first quarter of fiscal 2021. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

The following is a description of the valuation basis, including valuation techniques and inputs, used in measuring our financial assets and liabilities that are accounted for at fair value on a recurring basis: Corporate Equity Securities • Exchange-Traded Equity Securities: Exchange-traded equity securities are measured based on quoted closing exchange prices, which are generally obtained from external pricing services, and are categorized within Level 1 of the fair value hierarchy, otherwise they are categorized within Level 2 of the fair value hierarchy. To the extent these securities are actively traded, valuation adjustments are not applied. • Non-Exchange-Traded Equity Securities : Non-exchange-traded equity securities are measured primarily using broker quotations, pricing data from external pricing services and prices observed from recently executed market transactions and are categorized within Level 2 of the fair value hierarchy. Where such information is not available, non-exchange-traded equity securities are categorized within Level 3 of the fair value hierarchy and measured using valuation techniques involving quoted prices of or market data for comparable companies, similar company ratios and multiples (e.g., price/Earnings before interest, taxes, depreciation and amortization ("EBITDA"), price/book value), discounted cash flow analyses and transaction prices observed from subsequent financing or capital issuance by Jefferies Group. When using pricing data of comparable companies, judgment must be applied to adjust the pricing data to account for differences between the measured security and the comparable security (e.g., issuer market capitalization, yield, dividend rate, geographical concentration). • Equity Warrants: Non-exchange traded equity warrants are measured primarily using pricing data from external pricing services, prices observed from recently executed market transactions and broker quotations and are categorized within Level 2 of the fair value hierarchy. Where such information is not available, non-exchange-traded equity warrants are generally categorized within Level 3 of the fair value hierarchy and are measured using the Black-Scholes model with key inputs impacting the valuation including the underlying security price, implied volatility, dividend yield, interest rate curve, strike price and maturity date. Corporate Debt Securities • Investment Grade Corporate Bonds: Investment grade corporate bonds are measured primarily using pricing data from external pricing services and broker quotations, where available, prices observed from recently executed market transactions and bond spreads or credit default swap spreads of the issuer adjusted for basis differences between the swap curve and the bond curve. Corporate bonds measured using these valuation methods are categorized within Level 2 of the fair value hierarchy. If broker quotes, pricing data or spread data is not available, alternative valuation techniques are used including cash flow models incorporating interest rate curves, single name or index credit default swap curves for comparable issuers and recovery rate assumptions. Corporate bonds measured using alternative valuation techniques are categorized within Level 3 of the fair value hierarchy and are a limited portion of our corporate bonds. • High Yield Corporate and Convertible Bonds: A significant portion of our high yield corporate and convertible bonds are categorized within Level 2 of the fair value hierarchy and are measured primarily using broker quotations and pricing data from external pricing services, where available, and prices observed from recently executed market transactions of institutional size. Where pricing data is less observable, valuations are categorized within Level 3 of the fair value hierarchy and are based on pending transactions involving the issuer or comparable issuers, prices implied from an issuer's subsequent financing or recapitalization, models incorporating financial ratios and projected cash flows of the issuer and market prices for comparable issuers. Collateralized Debt Obligations and Collateralized Loan Obligations Collateralized debt obligations ("CDOs") and collateralized loan obligations ("CLOs") are measured based on prices observed from recently executed market transactions of the same or similar security or based on valuations received from third-party brokers or data providers and are categorized within Level 2 or Level 3 of the fair value hierarchy depending on the observability and significance of the pricing inputs. Valuation that is based on recently executed market transactions of similar securities incorporates additional review and analysis of pricing inputs and comparability criteria, including, but not limited to, collateral type, tranche type, rating, origination year, prepayment rates, default rates and loss severity. U.S. Government and Federal Agency Securities • U.S. Treasury Securities: U.S. Treasury securities are measured based on quoted market prices obtained from external pricing services and categorized within Level 1 of the fair value hierarchy. • U.S. Agency Debt Securities: Callable and non-callable U.S. agency debt securities are measured primarily based on quoted market prices obtained from external pricing services and are generally categorized within Level 1 or Level 2 of the fair value hierarchy. Municipal Securities Municipal securities are measured based on quoted prices obtained from external pricing services and are generally categorized within Level 2 of the fair value hierarchy. Sovereign Obligations Sovereign government obligations are measured based on quoted market prices obtained from external pricing services, where available, or recently executed independent transactions of comparable size. Sovereign government obligations, with consideration given to the country of issuance, are generally categorized in Level 1 or Level 2 of the fair value hierarchy. Residential Mortgage-Backed Securities • Agency Residential Mortgage-Backed Securities: Agency residential mortgage-backed securities include mortgage pass-through securities (fixed and adjustable rate), collateralized mortgage obligations and principal-only and interest-only (including inverse interest-only) securities. Agency residential mortgage-backed securities are generally measured using recent transactions, pricing data from external pricing services or expected future cash flow techniques that incorporate prepayment models and other prepayment assumptions to amortize the underlying mortgage loan collateral and are categorized within Level 2 of the fair value hierarchy. We use prices observed from recently executed transactions to develop market-clearing spread and yield curve assumptions. Valuation inputs with regard to the underlying collateral incorporate factors such as weighted average coupon, loan-to-value, credit scores, geographic location, maximum and average loan size, originator, servicer and weighted average loan age. • Non-Agency Residential Mortgage-Backed Securities: The fair value of non-agency residential mortgage-backed securities is determined primarily using discounted cash flow methodologies and securities are categorized within Level 2 or Level 3 of the fair value hierarchy based on the observability and significance of the pricing inputs used. Performance attributes of the underlying mortgage loans are evaluated to estimate pricing inputs, such as prepayment rates, default rates and the severity of credit losses. Attributes of the underlying mortgage loans that affect the pricing inputs include, but are not limited to, weighted average coupon; average and maximum loan size; loan-to-value; credit scores; documentation type; geographic location; weighted average loan age; originator; servicer; historical prepayment, default and loss severity experience of the mortgage loan pool; and delinquency rate. Yield curves used in the discounted cash flow models are based on observed market prices for comparable securities and published interest rate data to estimate market yields. In addition, broker quotes, where available, are also referenced to compare prices primarily on interest-only securities. Commercial Mortgage-Backed Securities • Agency Commercial Mortgage-Backed Securities: Government National Mortgage Association ("GNMA") project loan bonds are measured based on inputs corroborated from and benchmarked to observed prices of recent securitization transactions of similar securities with adjustments incorporating an evaluation of various factors, including prepayment speeds, default rates and cash flow structures, as well as the likelihood of pricing levels in the current market environment. Federal National Mortgage Association ("FNMA") Delegated Underwriting and Servicing ("DUS") mortgage-backed securities are generally measured by using prices observed from recently executed market transactions to estimate market-clearing spread levels for purposes of estimating fair value. GNMA project loan bonds and FNMA DUS mortgage-backed securities are categorized within Level 2 of the fair value hierarchy. • Non-Agency Commercial Mortgage-Backed Securities: Non-agency commercial mortgage-backed securities are measured using pricing data obtained from external pricing services, prices observed from recently executed market transactions or based on expected cash flow models that incorporate underlying loan collateral characteristics and performance. Non-agency commercial mortgage-backed securities are categorized within Level 2 or Level 3 of the fair value hierarchy depending on the observability of the underlying inputs. Other Asset-Backed Securities Other asset-backed securities include, but are not limited to, securities backed by auto loans, credit card receivables, student loans and other consumer loans and are categorized within Level 2 or Level 3 of the fair value hierarchy. Valuations are primarily determined using pricing data obtained from external pricing services, broker quotes and prices observed from recently executed market transactions. In addition, recent transaction data from comparable deals is deployed to develop market clearing yields and cumulative loss assumptions. The cumulative loss assumptions are based on the analysis of the underlying collateral and comparisons to earlier deals from the same issuer to gauge the relative performance of the deal. Loans and Other Receivables • Corporate Loans: Corporate loans categorized within Level 2 of the fair value hierarchy are measured based on market consensus pricing service quotations. Where available, market price quotations from external pricing services are reviewed to ensure they are supported by transaction data. Corporate loans categorized within Level 3 of the fair value hierarchy are measured based on price quotations that are considered to be less transparent, market prices for debt securities of the same creditor and estimates of future cash flows incorporating assumptions regarding creditor default and recovery rates and consideration of the issuer's capital structure. • Participation Certificates in Agency Residential Loans: Valuations of participation certificates in agency residential loans are based on observed market prices of recently executed purchases and sales of similar loans and data provider pricing. The loan participation certificates are categorized within Level 2 of the fair value hierarchy given the observability and volume of recently executed transactions and availability of data provider pricing. • Project Loans and Participation Certificates in GNMA Project and Construction Loans: Valuations of participation certificates in GNMA project and construction loans are based on inputs corroborated from and benchmarked to observed prices of recent securitizations with similar underlying loan collateral to derive an implied spread. Securitization prices are adjusted to estimate the fair value of the loans to account for the arbitrage that is realized at the time of securitization. The measurements are categorized within Level 2 of the fair value hierarchy given the observability and volume of recently executed transactions. • Consumer Loans and Funding Facilities: Consumer and small business whole loans and related funding facilities are valued based on observed market transactions and incorporating valuation inputs including, but not limited to, delinquency and default rates, prepayment rates, borrower characteristics, loan risk grades and loan age. These assets are categorized within Level 2 or Level 3 of the fair value hierarchy. • Escrow and Trade Claim Receivables: Escrow and trade claim receivables are categorized within Level 3 of the fair value hierarchy where fair value is estimated based on reference to market prices and implied yields of debt securities of the same or similar issuers. Escrow and trade claim receivables are categorized within Level 2 of the fair value hierarchy where fair value is based on recent observations in the same receivable. Derivatives • Listed Derivative Contracts: Listed derivative contracts that are actively traded are measured based on quoted exchange prices, broker quotes or vanilla option valuation models, such as Black-Scholes, using observable valuation inputs from the principal market or consensus pricing services. Exchange quotes and/or valuation inputs are generally obtained from external vendors and pricing services. Broker quotes are validated directly through observable and tradeable quotes. Listed derivative contracts that use unadjusted exchange close prices are generally categorized within Level 1 of the fair value hierarchy. All other listed derivative contracts are generally categorized within Level 2 of the fair value hierarchy. • Over-the-Counter ("OTC") Derivative Contracts: OTC derivative contracts are generally valued using models, whose inputs reflect assumptions that we believe market participants would use in valuing the derivative in a current transaction. Where available, valuation inputs are calibrated from observables market data. For many OTC derivative contracts, the valuation models do not involve material subjectivity as the methodologies do not entail significant judgment and the inputs to valuation models do not involve a high degree of subjectivity as the valuation model inputs are readily observable or can be derived from actively quoted markets. OTC derivative contracts are primarily categorized within Level 2 of the fair value hierarchy given the observability and significance of the inputs to the valuation models. Where significant inputs to the valuation are unobservable, derivative instruments are categorized within Level 3 of the fair value hierarchy. OTC options include OTC equity, foreign exchange, interest rate and commodity options measured using various valuation models, such as Black-Scholes, with key inputs including the underlying security price, foreign exchange spot rate, commodity price, implied volatility, dividend yield, interest rate curve, strike price and maturity date. Discounted cash flow models are utilized to measure certain OTC derivative contracts including the valuations of our interest rate swaps, which incorporate observable inputs related to interest rate curves, valuations of our foreign exchange forwards and swaps, which incorporate observable inputs related to foreign currency spot rates and forward curves and valuations of our commodity swaps and forwards, which incorporate observable inputs related to commodity spot prices and forward curves. Discounted cash flow models are also utilized to measure certain variable funding note swaps, which are backed by CLOs and incorporate constant prepayment rate, constant default rate and loss severity assumptions. Credit default swaps include both index and single-name credit default swaps. Where available, external data is used in measuring index credit default swaps and single-name credit default swaps. For commodity and equity total return swaps, market prices are generally observable for the underlying asset and used as the basis for measuring the fair value of the derivative contracts. Total return swaps executed on other underlyings are measured based on valuations received from external pricing services. • Oil Futures Derivatives: Vitesse Energy Finance uses swaps and call and put options in order to reduce exposure to future oil price fluctuations. Vitesse Energy Finance accounts for the derivative instruments at fair value, which are classified as either Level 1 or Level 2 within the fair value hierarchy. Fair values classified as Level 1 are measured based on quoted closing exchange prices obtained from external pricing services and Level 2 are determined under the income valuation technique using an option-pricing model that is based on directly or indirectly observable inputs. Investments at Fair Value Investments at fair value include investments in hedge funds, fund of funds and private equity funds, which are measured at the NAV of the funds, provided by the fund managers and are excluded from the fair value hierarchy. Investments at fair value also include direct equity investments in private companies, which are measured at fair value using valuation techniques involving quoted prices of or market data for comparable companies, similar company ratios and multiples (e.g., price/EBITDA, price/book value), discounted cash flow analyses, contingent claims analysis and transaction prices observed for subsequent financing or capital issuance by the company. Direct equity investments in private companies are categorized within Level 2 or Level 3 of the fair value hierarchy. The following tables present information about our investments in entities that have the characteristics of an investment company (in thousands): Fair Value (1) Unfunded Commitments February 28, 2019 Equity Long/Short Hedge Funds (2) $ 349,128 $ — Equity Funds (3) 35,719 20,036 Commodity Funds (4) 15,382 — Multi-asset Funds (5) 232,465 — Other funds (6) 336 — Total $ 633,030 $ 20,036 November 30, 2018 Equity Long/Short Hedge Funds (2) $ 86,788 $ — Equity Funds (3) 40,070 20,996 Commodity Funds (4) 10,129 — Multi-asset Funds (5) 256,972 — Other funds (6) 400 — Total $ 394,359 $ 20,996 (1) Where fair value is calculated based on NAV, fair value has been derived from each of the funds' capital statements. (2) This category includes investments in hedge funds that invest, long and short, primarily in equity securities in domestic and international markets in both the public and private sectors. At February 28, 2019 and November 30, 2018 , approximately 74% and 0% , respectively, of the fair value of investments in this category cannot be redeemed because these investments include restrictions that do not allow for redemption in the first 36 months after acquisition. At the end of this restriction period, which is in approximately 34 months , these investments are redeemable monthly with 45 to 90 days prior written notice. At February 28, 2019 and November 30, 2018 , 22% and 82% , respectively, of these investments are redeemable in 2020. At February 28, 2019 and November 30, 2018 , 4% and 17% , respectively, of these investments are redeemable quarterly with 60 days prior written notice. (3) The investments in this category include investments in equity funds that invest in the equity of various U.S. and foreign private companies in the energy, technology, internet service and telecommunication service industries. These investments cannot be redeemed; instead distributions are received through the liquidation of the underlying assets of the funds, which are expected to be liquidated in approximately one to ten years. (4) This category includes investments in a hedge fund that invests, long and short, primarily in commodities. Investments in this category are redeemable quarterly with 60 days prior written notice. (5) This category includes investments in hedge funds that invest, long and short, primarily in multi-asset securities in domestic and international markets in both the public and private sectors. At February 28, 2019 and November 30, 2018 , investments representing approximately 6% and 15% , respectively, of the fair value of investments in this category are redeemable monthly with 30 days prior written notice. (6) This category includes investments in a fund that invests in loans secured by a first trust deed on property, domestic and international public high yield debt, private high yield investments, senior bank loans, public leveraged equities, distressed debt and private equity investments and there are no redemption provisions. This category also includes investments in a fund of funds that invests in various private equity funds that are managed by Jefferies Group and have no redemption provisions. Investments in the fund of funds are gradually being liquidated, however, the timing of when the proceeds will be received is uncertain. Investments at fair value also include our investment in WeWork. We invested $9.0 million in WeWork in 2013 and currently own less than 1% of the company. Our interest in WeWork is reflected in Trading assets at fair value of $258.9 million and $254.4 million at February 28, 2019 and November 30, 2018 , respectively. Investment in FXCM FXCM is a provider of online foreign exchange trading services. In January 2015, we entered into a credit agreement with FXCM, and provided FXCM a $300 million senior secured term loan. $71.4 million of principal remained outstanding under the term loan as of February 28, 2019 . During the three months ended February 28, 2019 , interest accrued at 20.5% per annum. Through February 28, 2019 , we have received cumulatively $349.8 million of principal, interest and fees from our initial $279.0 million investment in FXCM. Our investment in the FXCM term loan is reported within Trading assets, at fair value in our Consolidated Statements of Financial Condition. We recorded income related to the term loan in Principal transactions revenues of $0.5 million during the three months ended February 28, 2019 and $8.6 million during the three months ended March 31, 2018 . We classify our equity investment in FXCM in our February 28, 2019 and November 30, 2018 Consolidated Statements of Financial Condition as Loans to and investments in associated companies, as we have the ability to significantly influence FXCM through our seats on the board of directors. We account for our equity interest on a one month lag. FXCM is considered a variable interest entity ("VIE") and our term loan and equity ownership are variable interests. We have determined that we are not the primary beneficiary of FXCM because we do not have the power to direct the activities that most significantly impact FXCM's performance. Therefore, we do not consolidate FXCM and we account for our equity interest under the equity method as an investment in an associated company. Our maximum exposure to loss as a result of our involvement with FXCM is limited to the carrying value of the term loan ( $73.6 million ) and the investment in associated company ( $72.5 million ), which totaled $146.1 million at February 28, 2019 . We estimate the fair value of our term loan by using a valuation model with inputs including management’s assumptions concerning the amount and timing of expected cash flows, the loan’s implied credit rating and effective yield. Because of these inputs and the degree of judgment involved, we have categorized our term loan within Level 3 of the fair value hierarchy. Long-term Debt Long-term debt includes variable rate, fixed-to-floating rate, constant maturity swap, digital and Bermudan structured notes. These are valued using various valuation models that incorporate Jefferies Group's own credit spread, market price quotations from external pricing sources referencing the appropriate interest rate curves, volatilities and other inputs as well as prices for transactions in a given note during the period. Long-term debt notes are generally categorized within Level 2 of the fair value hierarchy where market trades have been observed during the quarter, otherwise they are categorized within Level 3. Level 3 Rollforwards The following is a summary of changes in fair value of our financial assets and liabilities that have been categorized within Level 3 of the fair value hierarchy for the three months ended February 28, 2019 (in thousands): Three Months Ended February 28, 2019 Balance, November 30, 2018 Total gains/ losses (realized and unrealized) (1) Purchases Sales Settlements Issuances Net transfers into (out of) Level 3 Balance, February 28, 2019 Changes in unrealized gains/losses included in earnings relating to instruments still held at February 28, 2019 (1) Assets: Trading assets: Corporate equity securities $ 52,192 $ 4,488 $ 1,410 $ (2,411 ) $ (66 ) $ — $ (37 ) $ 55,576 $ 4,603 Corporate debt securities 9,484 466 3,568 (3,233 ) (834 ) — 1,479 10,930 498 CDOs and CLOs 36,105 (6,726 ) 49,201 (32,759 ) (1,139 ) — (1,538 ) 43,144 (3,526 ) Residential mortgage-backed securities 19,603 462 975 — (27 ) — (50 ) 20,963 494 Commercial mortgage-backed securities 10,886 136 12 — (41 ) — 1,827 12,820 96 Other asset-backed securities 53,175 (2,290 ) 29,195 (30,060 ) (12,320 ) — (1,814 ) 35,886 (1,763 ) Loans and other receivables 46,985 814 40,061 (27,142 ) (1,990 ) — 19,323 78,051 130 Investments at fair value 396,254 (2,923 ) 27,767 — — — — 421,098 (2,923 ) FXCM term loan 73,150 450 — — — — — 73,600 450 Liabilities: Trading liabilities: Corporate equity securities $ — $ (2 ) $ — $ 80 $ — $ — $ — $ 78 $ 2 Corporate debt securities 522 (241 ) — — — — 449 730 241 Commercial mortgage-backed securities — 70 — — — — — 70 (70 ) Loans 6,376 (229 ) (1,411 ) 504 — — (1,820 ) 3,420 338 Net derivatives (2) 21,614 (5,348 ) (2,804 ) 3,084 169 — 12,260 28,975 3,333 Long-term debt (1) 200,745 (16,701 ) — — (5,665 ) 92,016 12,744 283,139 4,045 (1) Realized and unrealized gains (losses) are primarily reported in Principal transactions revenues in the Consolidated Statements of Operations. Changes in instrument-specific credit risk related to structured notes are included in our Consolidated Statements of Comprehensive Income (Loss), net of tax. Changes in unrealized gains (losses) included in other comprehensive income (loss) for instruments still held at February 28, 2019 were gains of $12.7 million . (2) Net derivatives represent Trading assets - Derivatives and Trading liabilities - Derivatives. Analysis of Level 3 Assets and Liabilities for the three months ended February 28, 2019 During the three months ended February 28, 2019 , transfers of assets of $60.4 million from Level 2 to Level 3 of the fair value hierarchy are primarily attributed to: • Loans and other receivables of $25.8 million , CDOs and CLOs of $14.1 million and other asset-backed securities of $10.8 million due to reduced pricing transparency. During the three months ended February 28, 2019 , transfers of assets of $41.2 million from Level 3 to Level 2 are primarily attributed to: • CDOs and CLOs of $15.7 million , other asset-backed securities of $12.6 million and loans and other receivables of $6.5 million due to greater pricing transparency supporting classification into Level 2. During the three months ended February 28, 2019 , transfers of liabilities of $36.6 million from Level 2 to Level 3 of the fair value hierarchy are primarily attributed to: • Structured notes of $22.2 million and net derivatives of $13.9 million due to reduced market and pricing transparency. During the three months ended February 28, 2019 , transfers of liabilities of $12.9 million from Level 3 to Level 2 of the fair value hierarchy are primarily attributed to: • Structured notes of $9.4 million due to greater market transparency. Net losses on Level 3 assets were $5.1 million and net gains on Level 3 liabilities were $22.5 million for the three months ended February 28, 2019 . Net losses on Level 3 assets were primarily due to decreased market values across CDOs and CLOs, other asset-backed securities and investments at fair value, partially offset by increased market values across corporate equity securities. Net gains on Level 3 liabilities were primarily due to decreased valuations of certain structured notes. The following is a summary of changes in fair val

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Derivative Financial Instruments Derivative activities are recorded at fair value in the Consolidated Statements of Financial Condition in Trading assets and Trading liabilities, net of cash paid or received under credit support agreements and on a net counterparty basis when a legally enforceable right to offset exists under a master netting agreement. Predominantly, Jefferies Group enters into derivative transactions to satisfy the needs of its clients and to manage its own exposure to market and credit risks resulting from its trading activities. In addition, Jefferies Group applies hedge accounting to an interest rate swap that has been designated as a fair value hedge of the changes in fair value due to the benchmark interest rate for certain fixed rate senior long-term debt. See Notes 3 and 20 for additional disclosures about derivative financial instruments. Derivatives are subject to various risks similar to other financial instruments, including market, credit and operational risk. The risks of derivatives should not be viewed in isolation, but rather should be considered on an aggregate basis along with our other trading-related activities. Jefferies Group manages the risks associated with derivatives on an aggregate basis along with the risks associated with proprietary trading as part of its firm wide risk management policies. In connection with Jefferies Group's derivative activities, Jefferies Group may enter into International Swaps and Derivatives Association, Inc. ("ISDA") master netting agreements or similar agreements with counterparties. See Note 10 for additional information regarding the offsetting of derivative contracts. The following table presents the fair value and related number of derivative contracts categorized by type of derivative contract as reflected in the Consolidated Statements of Financial Condition at February 28, 2019 and November 30, 2018 .

Collateralized Transactions [Abstract]
Collateralized Transactions	Collateralized Transactions Jefferies Group enters into secured borrowing and lending arrangements to obtain collateral necessary to effect settlement, finance inventory positions, meet customer needs or re-lend as part of dealer operations. Jefferies Group monitors the fair value of the securities loaned and borrowed on a daily basis as compared with the related payable or receivable, and requests additional collateral or returns excess collateral, as appropriate. Jefferies Group pledges financial instruments as collateral under repurchase agreements, securities lending agreements and other secured arrangements, including clearing arrangements. Jefferies Group's agreements with counterparties generally contain contractual provisions allowing the counterparty the right to sell or repledge the collateral. Pledged securities owned that can be sold or repledged by the counterparty are included in Financial instruments owned, at fair value and noted parenthetically as Securities pledged in our Consolidated Statements of Financial Condition. The following tables set forth the carrying value of securities lending arrangements and repurchase agreements by class of collateral pledged and remaining contractual maturity (in thousands): Collateral Pledged Securities Lending Arrangements Repurchase Agreements Total February 28, 2019 Corporate equity securities $ 1,860,725 $ 277,041 $ 2,137,766 Corporate debt securities 269,547 1,915,333 2,184,880 Mortgage- and asset-backed securities — 3,277,181 3,277,181 U.S. government and federal agency securities 104,428 11,987,128 12,091,556 Municipal securities — 466,849 466,849 Sovereign obligations — 3,387,020 3,387,020 Loans and other receivables — 352,411 352,411 Total $ 2,234,700 $ 21,662,963 $ 23,897,663 November 30, 2018 Corporate equity securities $ 1,505,218 $ 487,124 $ 1,992,342 Corporate debt securities 333,221 1,853,309 2,186,530 Mortgage- and asset-backed securities 249 2,820,543 2,820,792 U.S. government and federal agency securities — 8,181,947 8,181,947 Municipal securities — 604,274 604,274 Sovereign obligations — 2,945,521 2,945,521 Loans and other receivables — 300,768 300,768 Total $ 1,838,688 $ 17,193,486 $ 19,032,174 Contractual Maturity Overnight and Continuous Up to 30 Days 30 to 90 Days Greater than 90 Days Total February 28, 2019 Securities lending arrangements $ 1,034,306 $ — $ 1,002,932 $ 197,462 $ 2,234,700 Repurchase agreements 11,379,518 4,169,261 4,223,211 1,890,973 21,662,963 Total $ 12,413,824 $ 4,169,261 $ 5,226,143 $ 2,088,435 $ 23,897,663 November 30, 2018 Securities lending arrangements $ 807,347 $ — $ 560,417 $ 470,924 $ 1,838,688 Repurchase agreements 7,849,052 1,915,325 6,042,951 1,386,158 17,193,486 Total $ 8,656,399 $ 1,915,325 $ 6,603,368 $ 1,857,082 $ 19,032,174 Jefferies Group receives securities as collateral under resale agreements, securities borrowing transactions and customer margin loans. Jefferies Group also receives securities as collateral in connection with securities-for-securities transactions in which it is the lender of securities. In many instances, Jefferies Group is permitted by contract to rehypothecate the securities received as collateral. These securities may be used to secure repurchase agreements, enter into securities lending transactions, satisfy margin requirements on derivative transactions or cover short positions. At February 28, 2019 and November 30, 2018 , the approximate fair value of securities received as collateral by Jefferies Group that may be sold or repledged was $28.2 billion and $23.1 billion , respectively.

Securitization Activities

Securitization Activities [Abstract]
Securitization Activities	Securitization Activities Jefferies Group engages in securitization activities related to corporate loans, commercial mortgage loans, consumer loans and mortgage-backed and other asset-backed securities. In securitization transactions, Jefferies Group transfers these assets to special purpose entities ("SPEs") and acts as the placement or structuring agent for the beneficial interests sold to investors by the SPE. A significant portion of the securitization transactions are the securitization of assets issued or guaranteed by U.S. government agencies. These SPEs generally meet the criteria of VIEs; however, the SPEs are generally not consolidated as Jefferies Group is not considered the primary beneficiary for these SPEs. Jefferies Group accounts for its securitization transactions as sales, provided it has relinquished control over the transferred assets. Transferred assets are carried at fair value with unrealized gains and losses reflected in Principal transactions revenues in the Consolidated Statements of Operations prior to the identification and isolation for securitization. Subsequently, revenues recognized upon securitization are reflected as net underwriting revenues. Jefferies Group generally receives cash proceeds in connection with the transfer of assets to an SPE. Jefferies Group may, however, have continuing involvement with the transferred assets, which is limited to retaining one or more tranches of the securitization (primarily senior and subordinated debt securities in the form of mortgage- and other asset-backed securities or CLOs). These securities are included in Trading assets in our Consolidated Statements of Financial Condition and are generally initially categorized as Level 2 within the fair value hierarchy. The following table presents activity related to Jefferies Group's securitizations that were accounted for as sales in which it had continuing involvement (in millions): For the Three Months Ended February 28, 2019 March 31, 2018 Transferred assets $ 1,260.6 $ 2,757.8 Proceeds on new securitizations $ 1,331.2 $ 2,758.9 Cash flows received on retained interests $ 14.8 $ 9.2 Jefferies Group has no explicit or implicit arrangements to provide additional financial support to these SPEs, has no liabilities related to these SPEs and has no outstanding derivative contracts executed in connection with these securitizations at February 28, 2019 and November 30, 2018 . The following table summarizes Jefferies Group's retained interests in SPEs where it transferred assets and has continuing involvement and received sale accounting treatment (in millions): February 28, 2019 November 30, 2018 Securitization Type Total Assets Retained Interests Total Assets Retained Interests U.S. government agency residential mortgage-backed securities $ 12,620.2 $ 353.1 $ 13,633.5 $ 365.3 U.S. government agency commercial mortgage-backed securities $ 1,594.4 $ 70.7 $ 2,027.6 $ 185.6 CLOs $ 3,522.8 $ 23.7 $ 3,512.0 $ 20.9 Consumer and other loans $ 938.0 $ 61.3 $ 604.1 $ 48.9 Total assets represent the unpaid principal amount of assets in the SPEs in which Jefferies Group has continuing involvement and are presented solely to provide information regarding the size of the transactions and the size of the underlying assets supporting its retained interests, and are not considered representative of the risk of potential loss. Assets retained in connection with a securitization transaction represent the fair value of the securities of one or more tranches issued by an SPE, including senior and subordinated tranches. Jefferies Group's risk of loss is limited to this fair value amount which is included in total Trading assets in our Consolidated Statements of Financial Condition. Although not obligated, in connection with secondary market-making activities Jefferies Group may make a market in the securities issued by these SPEs. In these market-making transactions, Jefferies Group buys these securities from and sells these securities to investors. Securities purchased through these market-making activities are not considered to be continuing involvement in these SPEs. To the extent Jefferies Group purchased securities through these market-making activities and Jefferies Group is not deemed to be the primary beneficiary of the VIE, these securities are included in agency and non-agency mortgage- and asset-backed securitizations in the nonconsolidated VIEs section presented in Note 8. Foursight Capital also utilizes SPEs to securitize automobile loans receivable. These SPEs are VIEs and our subsidiary is the primary beneficiary; the related assets and the secured borrowings are recognized in the Consolidated Statements of Financial Condition. These secured borrowings do not have recourse to our subsidiary's general credit. See Note 8 for further information on securitization activities and VIEs.

Variable Interest Entities

Variable Interest Entities	3 Months Ended

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities VIEs are entities in which equity investors lack the characteristics of a controlling financial interest. VIEs are consolidated by the primary beneficiary. The primary beneficiary is the party who has both (1) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (2) an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity. Our variable interests in VIEs include debt and equity interests, equity interests in associated companies, commitments, guarantees and certain fees. Our involvement with VIEs arises primarily from the following activities, but also includes other activities discussed below: • Purchases of securities in connection with Jefferies Group's trading and secondary market-making activities; • Retained interests held as a result of securitization activities, including the resecuritization of mortgage- and other asset-backed securities and the securitization of commercial mortgage, corporate and consumer loans; • Acting as placement agent and/or underwriter in connection with client-sponsored securitizations; • Financing of agency and non-agency mortgage- and other asset-backed securities; • Warehouse funding arrangements for client-sponsored consumer loan vehicles and CLOs through participation certificates, forward sale agreements and revolving loan and note commitments; and • Loans to, investments in and fees from various investment vehicles. We determine whether we are the primary beneficiary of a VIE upon our initial involvement with the VIE and we reassess whether we are the primary beneficiary of a VIE on an ongoing basis. Our determination of whether we are the primary beneficiary of a VIE is based upon the facts and circumstances for each VIE and requires judgment. Our considerations in determining the VIE's most significant activities and whether we have power to direct those activities include, but are not limited to, the VIE's purpose and design and the risks passed through to investors, the voting interests of the VIE, management, service and/or other agreements of the VIE, involvement in the VIE's initial design and the existence of explicit or implicit financial guarantees. In situations where we have determined that the power over the VIE's significant activities is shared, we assess whether we are the party with the power over the most significant activities. If we are the party with the power over the most significant activities, we meet the "power" criteria of the primary beneficiary. If we do not have the power over the most significant activities or we determine that decisions require consent of each sharing party, we do not meet the "power" criteria of the primary beneficiary. We assess our variable interests in a VIE both individually and in aggregate to determine whether we have an obligation to absorb losses of or a right to receive benefits from the VIE that could potentially be significant to the VIE. The determination of whether our variable interest is significant to the VIE requires judgment. In determining the significance of our variable interest, we consider the terms, characteristics and size of the variable interests, the design and characteristics of the VIE, our involvement in the VIE and our market-making activities related to the variable interests. Consolidated VIEs The following table presents information about the assets and liabilities of our consolidated securitization vehicles VIEs, which are presented in our Consolidated Statements of Financial Condition in the respective asset and liability categories (in millions). The assets and liabilities in the table below are presented prior to consolidation and thus a portion of these assets and liabilities are eliminated in consolidation. February 28, 2019 November 30, 2018 Financial instruments owned $ 323.4 $ — Securities purchased under agreement to resell (1) 936.3 883.1 Receivables 613.5 626.0 Other 33.0 78.4 Total assets $ 1,906.2 $ 1,587.5 Other secured financings (2) $ 1,853.3 $ 1,535.3 Other (3) 48.6 45.9 Total liabilities $ 1,901.9 $ 1,581.2 (1) Securities purchased under agreements to resell represent an amount due under a collateralized transaction on a related consolidated entity, which is eliminated in consolidation. (2) Approximately $326.6 million and $1.0 million of the secured financings represent amounts held by Jefferies Group in inventory and are eliminated in consolidation at February 28, 2019 and November 30, 2018 , respectively. (3) Includes $47.1 million and $44.1 million at February 28, 2019 and November 30, 2018 , respectively, of intercompany payables that are eliminated in consolidation. Securitization Vehicles. Jefferies Group is the primary beneficiary of asset-backed financing vehicles to which Jefferies Group sells agency and non-agency residential and commercial mortgage loans, and mortgage-backed securities and consumer loans pursuant to the terms of a master repurchase agreement. Jefferies Group's variable interests in these vehicles consist of its collateral margin maintenance obligations under the master repurchase agreement, which Jefferies Group manages, and retained interests in securities issued. The assets of these VIEs consist of reverse repurchase agreements, which are available for the benefit of the vehicle's debt holders. The creditors of these VIEs do not have recourse to Jefferies Group's general credit and each such VIE's assets are not available to satisfy any other debt. Jefferies Group is also the primary beneficiary of securitization vehicles to which it sold agency residential mortgage-backed securities and retained all of the interests issued by these vehicles. Jefferies Group's variable interests in these vehicles consist of its retained interests in the securities issued. The assets of these VIEs consist of agency residential mortgage-backed securities. At February 28, 2019 and November 30, 2018 , Foursight Capital is the primary beneficiary of SPEs it utilized to securitize automobile loans receivable. Foursight Capital acts as the servicer for which it receives a fee, and owns an equity interest in the SPEs. The notes issued by the SPEs are secured solely by the assets of the SPEs and do not have recourse to Foursight Capital’s general credit and the assets of the VIEs are not available to satisfy any other debt. Nonconsolidated VIEs The following tables present information about our variable interests in nonconsolidated VIEs (in millions): Financial Statement Carrying Amount Maximum Exposure to Loss VIE Assets Assets Liabilities February 28, 2019 CLOs $ 156.8 $ 3.8 $ 1,939.5 $ 4,887.2 Consumer loan and other asset-backed vehicles 445.5 — 771.6 3,491.0 Related party private equity vehicles 31.6 — 49.4 90.8 Other investment vehicles 461.1 — 471.5 7,175.1 Total $ 1,095.0 $ 3.8 $ 3,232.0 $ 15,644.1 November 30, 2018 CLOs $ 45.2 $ — $ 571.4 $ 3,281.9 Consumer loan and other asset-backed vehicles 462.1 — 807.1 3,273.1 Related party private equity vehicles 35.5 — 53.5 108.3 Other investment vehicles 203.6 — 214.7 5,719.1 Total $ 746.4 $ — $ 1,646.7 $ 12,382.4 Our maximum exposure to loss often differs from the carrying value of the variable interests. The maximum exposure to loss is dependent on the nature of the variable interests in the VIEs and is limited to the notional amounts of certain loan and equity commitments and guarantees. Our maximum exposure to loss does not include the offsetting benefit of any financial instruments that may be utilized to hedge the risks associated with its variable interests and is not reduced by the amount of collateral held as part of a transaction with a VIE. Collateralized Loan Obligations. Assets collateralizing the CLOs include bank loans, participation interests and sub-investment grade and senior secured U.S. loans. Jefferies Group underwrites securities issued in CLO transactions on behalf of sponsors and provides advisory services to the sponsors. Jefferies Group may also sell corporate loans to the CLOs. Jefferies Group's variable interests in connection with CLOs where it has been involved in providing underwriting and/or advisory services consist of the following: • Forward sale agreements whereby Jefferies Group commits to sell, at a fixed price, corporate loans and ownership interests in an entity holding such corporate loans to CLOs; • Warehouse funding arrangements in the form of participation interests in corporate loans held by CLOs and commitments to fund such participation interests; • Trading positions in securities issued in a CLO transaction; and • Investments in variable funding notes issued by CLOs. Consumer Loan and Other Asset-Backed Vehicles. Jefferies Group provides financing and lending related services to certain client-sponsored VIEs in the form of revolving funding note agreements, revolving credit facilities and forward purchase agreements. The underlying assets, which are collateralizing the vehicles, are primarily composed of unsecured consumer and small business loans, and trust preferred securities. In addition, Jefferies Group may provide structuring and advisory services and act as an underwriter or placement agent for securities issued by the vehicles. Jefferies Group does not control the activities of these entities. Related Party Private Equity Vehicles. Jefferies Group committed to invest equity in private equity funds (the "JCP Funds") managed by Jefferies Capital Partners, LLC (the "JCP Manager"). Additionally, Jefferies Group committed to invest equity in the general partners of the JCP Funds (the "JCP General Partners") and the JCP Manager. Jefferies Group's variable interests in the JCP Funds, JCP General Partners and JCP Manager (collectively, the "JCP Entities") consist of equity interests that, in total, provide Jefferies Group with limited and general partner investment returns of the JCP Funds, a portion of the carried interest earned by the JCP General Partners and a portion of the management fees earned by the JCP Manager. At February 28, 2019 and November 30, 2018 , Jefferies Group's total equity commitment in the JCP Entities was $139.3 million and $139.3 million , respectively, of which $121.5 million and $121.3 million , respectively, had been funded. The carrying value of Jefferies Group's equity investments in the JCP Entities was $31.6 million and $35.5 million at February 28, 2019 and November 30, 2018 , respectively. Jefferies Group's exposure to loss is limited to the total of its carrying value and unfunded equity commitment. The assets of the JCP Entities primarily consist of private equity and equity related investments. Other Investment Vehicles. The carrying amount of our equity investment was $461.1 million and $203.6 million at February 28, 2019 and November 30, 2018 , respectively. Our unfunded equity commitment related to these investments totaled $10.4 million and $11.1 million at February 28, 2019 and November 30, 2018 , respectively. Our exposure to loss is limited to the total of our carrying value and unfunded equity commitment. These investment vehicles have assets primarily consisting of private and public equity investments, debt instruments and various oil and gas assets. Mortgage- and Other Asset-Backed Securitization Vehicles. In connection with Jefferies Group's secondary trading and market-making activities, Jefferies Group buys and sells agency and non-agency mortgage-backed securities and other asset-backed securities, which are issued by third-party securitization SPEs and are generally considered variable interests in VIEs. Securities issued by securitization SPEs are backed by residential mortgage loans, U.S. agency collateralized mortgage obligations, commercial mortgage loans, CDOs and CLOs and other consumer loans, such as installment receivables, auto loans and student loans. These securities are accounted for at fair value and included in Trading assets in our Consolidated Statements of Financial Condition. Jefferies Group has no other involvement with the related SPEs and therefore does not consolidate these entities. Jefferies Group also engages in underwriting, placement and structuring activities for third-party-sponsored securitization trusts generally through agency (FNMA ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac") or GNMA ("Ginnie Mae")) or non-agency-sponsored SPEs and may purchase loans or mortgage-backed securities from third parties that are subsequently transferred into the securitization trusts. The securitizations are backed by residential and commercial mortgage, home equity and auto loans. Jefferies Group does not consolidate agency-sponsored securitizations as it does not have the power to direct the activities of the SPEs that most significantly impact their economic performance. Further, Jefferies Group is not the servicer of non-agency-sponsored securitizations and therefore does not have power to direct the most significant activities of the SPEs and accordingly, does not consolidate these entities. Jefferies Group may retain unsold senior and/or subordinated interests at the time of securitization in the form of securities issued by the SPEs. At February 28, 2019 and November 30, 2018 , Jefferies Group held $2,821.0 million and $2,913.0 million of agency mortgage-backed securities, respectively, and $167.0 million and $170.5 million of non-agency mortgage- and other asset-backed securities, respectively, as a result of its secondary trading and market-making activities, and underwriting, placement and structuring activities. Jefferies Group's maximum exposure to loss on these securities is limited to the carrying value of its investments in these securities. These mortgage- and other asset-backed securitization vehicles discussed are not included in the above table containing information about Jefferies Group's variable interests in nonconsolidated VIEs. We also have a variable interest in a nonconsolidated VIE consisting of our senior secured term loan receivable and equity interest in FXCM. See Notes 3 and 9 for further discussion.

(3) As further described in Note 3, our investment in FXCM includes both our equity method investment in FXCM and our term loan with FXCM. Our equity method investment is included in Loans to and investments in associated companies and our term loan is included in Trading assets, at fair value in our Consolidated Statements of Financial Condition. (4) During the third quarter of 2018, we sold 100% of our equity interests in Garcadia and our associated real estate to our former partners, the Garff family.

Jefferies Finance is a commercial finance company whose primary focus is the origination and syndication of senior secured debt to middle market and growth companies in the form of term and revolving loans. Loans are originated primarily through the investment banking efforts of Jefferies Group. Jefferies Finance may also originate other debt products such as second lien term, bridge and mezzanine loans, as well as related equity co-investments. Jefferies Finance also purchases syndicated loans in the secondary market and acts as an investment advisor for various loan funds. At February 28, 2019 , Jefferies Group and MassMutual each had equity commitments to Jefferies Finance of $750.0 million . At February 28, 2019 , $622.9 million of Jefferies Group's commitment was funded. The investment commitment is scheduled to expire on March 1, 2020 with automatic one year extensions absent a 60 -day termination notice by either party. Jefferies Finance has executed a Secured Revolving Credit Facility with Jefferies Group and MassMutual, to be funded equally, to support loan underwritings by Jefferies Finance, which bears interest based on the interest rates of the related Jefferies Finance underwritten loans and is secured by the underlying loans funded by the proceeds of the facility. The total Secured Revolving Credit Facility is a committed amount of $500.0 million at February 28, 2019 and November 30, 2018 . Advances are shared equally between Jefferies Group and MassMutual. The facility is scheduled to mature on March 1, 2020 with automatic one year extensions absent a 60 -day termination notice by either party. At February 28, 2019 and November 30, 2018 , none of Jefferies Group's $250.0 million commitment was funded. Jefferies Group recognized interest income and unfunded commitment fees related to the facility of $0.3 million and $1.0 million during the three months ended February 28, 2019 and March 31, 2018 , respectively. Jefferies Group engages in debt capital markets transactions with Jefferies Finance related to the originations and syndications of loans by Jefferies Finance. In connection with such services, Jefferies Group earned fees of $21.9 million and $101.4 million during the three months ended February 28, 2019 and March 31, 2018 , respectively, which are recognized in Investment banking revenues in the Consolidated Statements of Operations. In addition, Jefferies Group paid fees to Jefferies Finance in respect of certain loans originated by Jefferies Finance of $5.4 million and $18.5 million during the three months ended February 28, 2019 and March 31, 2018 , respectively, which are recognized within Selling, general and other expenses in the Consolidated Statements of Operations. During the three months ended February 28, 2019 and March 31, 2018 , Jefferies Group acted as a placement agent for CLOs managed by Jefferies Finance, for which Jefferies Group recognized fees of $1.3 million and $0.3 million , respectively, which are included in Investment banking revenues in the Consolidated Statements of Operations. At February 28, 2019 and November 30, 2018 , Jefferies Group held securities issued by CLOs managed by Jefferies Finance, which are included in Trading assets. Additionally, Jefferies Group has entered into participation agreements and derivative contracts with Jefferies Finance based upon certain securities issued by the CLO. Gains (losses) related to the derivative contracts were not material. Under a service agreement, Jefferies Group charged Jefferies Finance $27.1 million and $26.1 million for services provided during the three months ended February 28, 2019 and March 31, 2018 , respectively. At February 28, 2019 , Jefferies Group had a receivable from Jefferies Finance, included in Other assets in the Consolidated Statement of Financial Condition, of $10.7 million and a payable to Jefferies Finance, related to cash deposited with Jefferies Group, included in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition of $13.9 million . At November 30, 2018 , Jefferies Group had a receivable from Jefferies Finance, included in Other assets in the Consolidated Statement of Financial Condition, of $35.2 million and a payable to Jefferies Finance, related to cash deposited with Jefferies Group, included in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition, of $14.1 million . Jefferies Group enters into OTC foreign exchange contracts with Jefferies Finance. In connection with these contracts Jefferies Group had $0.2 million recorded in Trading assets in our Consolidated Statement of Financial Condition at February 28, 2019 and $0.2 million recorded in Payables, expense accruals and other liabilities and $0.4 million included in Trading liabilities in our Consolidated Statement of Financial Condition at November 30, 2018 . Subsequent to quarter-end, on March 28, 2019, Jefferies Group entered into a promissory note with Jefferies Finance with a principal amount of $1.0 billion , the proceeds of which are being used in connection with Jefferies Group's investment banking loan syndication activities. Interest is based on the London Interbank Offered Rate ("LIBOR") plus 5.00% per annum. Jefferies Group agrees to pay Jefferies Finance the entire outstanding principal amount of this note no later than May 15, 2019. Berkadia Berkadia is a commercial mortgage banking and servicing joint venture formed in 2009 with Berkshire Hathaway Inc. We and Berkshire Hathaway each contributed $217.2 million of equity capital to the joint venture and each have a 50% membership interest in Berkadia. We are entitled to receive 45% of the profits. Berkadia originates commercial/multifamily real estate loans that are sold to U.S. government agencies, and originates and brokers commercial/multifamily mortgage loans which are not part of government agency programs. Berkadia is an investment sales adviser focused on the multifamily industry. Berkadia is a servicer of commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions. Berkadia uses all of the proceeds from the commercial paper sales of an affiliate of Berkadia to fund new mortgage loans, servicer advances, investments and other working capital requirements. Repayment of the commercial paper is supported by a $1.5 billion surety policy issued by a Berkshire Hathaway insurance subsidiary and corporate guaranty, and we have agreed to reimburse Berkshire Hathaway for one-half of any losses incurred thereunder. At February 28, 2019 , the aggregate amount of commercial paper outstanding was $1.47 billion . National Beef National Beef processes and markets fresh and chilled boxed beef, ground beef, beef by-products, consumer-ready beef and pork, and wet blue leather for domestic and international markets. As discussed in Note 24, on June 5, 2018, we completed the sale of 48% of National Beef to Marfrig, reducing our ownership in National Beef to 31% . As of the closing of the sale on June 5, 2018, we deconsolidated our investment in National Beef and account for our remaining interest under the equity method of accounting. We are amortizing our basis difference between the estimated fair value and the underlying book value of National Beef's customer relationships, tradenames, cattle supply contracts and property, plant and equipment over their respective useful lives (weighted average life of 15 years ). FXCM As discussed more fully in Note 3, at February 28, 2019 , Jefferies has a 50% voting interest in FXCM and a senior secured term loan to FXCM due in the second quarter of 2019. On September 1, 2016, we gained the ability to significantly influence FXCM through our seats on the board of directors. As a result, we classify our equity investment in FXCM in our Consolidated Statements of Financial Condition as Loans to and investments in associated companies. Our term loan remains classified within Trading assets, at fair value. We account for our equity interest in FXCM on a one month lag. We are amortizing our basis difference between the estimated fair value and the underlying book value of FXCM customer relationships, technology, tradename and long-term debt over their respective useful lives (weighted average life of 11 years ). FXCM is considered a VIE and our term loan and equity interest are variable interests. We have determined that we are not the primary beneficiary of FXCM because we do not have the power to direct the activities that most significantly impact FXCM's performance. Therefore, we do not consolidate FXCM. Garcadia Garcadia was a joint venture between us and Garff Enterprises, Inc. ("Garff") that owned and operated automobile dealerships comprised of domestic and foreign automobile makers. In the third quarter of 2018, we sold 100% of our equity interests in Garcadia and our associated real estate to our former partners, the Garff family. Linkem We own approximately 42% of the common shares of Linkem, a fast-growing fixed wireless broadband services provider in Italy. In addition, we own convertible preferred stock, which is automatically convertible to common shares in 2022. If all of our convertible preferred stock was converted, it would increase our ownership to approximately 54% of Linkem’s common equity at February 28, 2019 . We have approximately 48% of the total voting securities of Linkem. We account for our equity interest in Linkem on a two month lag. HomeFed At February 28, 2019 , we own 10,852,123 shares of HomeFed’s common stock, representing approximately 70% of HomeFed’s outstanding common shares; however, we have contractually agreed to limit our voting rights such that we will not be able to vote more than 45% of HomeFed’s total voting securities voting on any matter, assuming all HomeFed shares not owned by us are voted. HomeFed develops and owns residential and mixed-use real estate properties. HomeFed is a public company traded on the Over-the-Counter Bulletin Board (Symbol: HOFD). As a result of a 1998 distribution to all of our shareholders, approximately 5% of HomeFed is beneficially owned by our Chairman at February 28, 2019 . Three of our executives serve on the board of directors of HomeFed, including our Chairman who serves as HomeFed’s Chairman, and our President. Since we do not control HomeFed, our investment in HomeFed is accounted for under the equity method as an investment in an associated company. We account for our equity interest in HomeFed on a two month lag.

Mandatorily Redeemable Convertible Preferred Shares In connection with our acquisition of Jefferies Group in March 2013, we issued a new series of 3.25% Cumulative Convertible Preferred Shares ("Preferred Shares") ( $125.0 million at mandatory redemption value) in exchange for Jefferies Group's outstanding 3.25% Series A-1 Cumulative Convertible Preferred Stock. The Preferred Shares have a 3.25% annual, cumulative cash dividend and are currently convertible into 4,162,200 common shares, an effective conversion price of $30.03 per share. The holders of the Preferred Shares are also entitled to an additional quarterly payment in the event we declare and pay a dividend on our common stock in an amount greater than $0.0625 per common share per quarter. The additional quarterly payment would be paid to the holders of Preferred Shares on an as converted basis and on a per share basis would equal the quarterly dividend declared and paid to a holder of a share of common stock in excess of $0.0625 per share. In the third quarter of 2017, we increased our quarterly dividend from $0.0625 to $0.10 per common share. In the third quarter of 2018, we increased our quarterly dividend from $0.10 to $0.125 per common share. These increased the preferred stock dividend from $1.2 million for the three months ended March 31, 2018 to $1.3 million for the three months ended February 28, 2019 . The Preferred Shares are callable beginning in 2023 at a price of $1,000 per share plus accrued interest and are mandatorily redeemable in 2038.

Compensation Plans	Compensation Plans Restricted Stock and Restricted Stock Units. Restricted stock and restricted stock units ("RSUs") may be granted to new employees as "sign-on" awards, to existing employees as "retention" awards and to certain executive officers as awards for multiple years. Sign-on and retention awards are generally subject to annual ratable vesting over a four year service period and are amortized as compensation expense on a straight-line basis over the related four years. Restricted stock and RSUs are granted to certain senior executives with market, performance and service conditions. Market conditions are incorporated into the grant-date fair value of senior executive awards using a Monte Carlo valuation model. Compensation expense for awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. Awards with performance conditions are amortized over the service period if it is determined that it is probable that the performance condition will be achieved. Stock-Based Compensation Expense. Compensation and benefits expense included $11.8 million and $12.4 million for the three months ended February 28, 2019 and March 31, 2018 , respectively, for share-based compensation expense relating to grants made under our share-based compensation plans. Total compensation cost includes the amortization of sign-on, retention and senior executive awards, less forfeitures and clawbacks. The total tax benefit recognized in results of operations related to share-based compensation expenses was $3.0 million and $2.9 million for the three months ended February 28, 2019 and March 31, 2018 , respectively. At February 28, 2019 , total unrecognized compensation cost related to nonvested share-based compensation plans was $109.9 million ; this cost is expected to be recognized over a weighted average period of three years. At February 28, 2019 , there were 1,821,000 shares of restricted stock outstanding with future service required, 5,958,000 RSUs outstanding with future service required (including target RSUs issuable under the senior executive compensation plan), 14,434,000 RSUs outstanding with no future service required and 715,000 shares issuable under other plans. The maximum potential increase to common shares outstanding resulting from these outstanding awards is 21,107,000 . Restricted Cash Awards. Jefferies Group provides compensation to certain new and existing employees in the form of loans and/or other cash awards which are subject to ratable vesting terms with service requirements. These awards are amortized to compensation expense over the relevant service period, which is generally considered to start at the beginning of the annual compensation year. At February 28, 2019 , the remaining unamortized amount of the restricted cash awards was $591.3 million and is included within Other assets in the Consolidated Statement of Financial Condition; this cost is expected to be recognized over a weighted average period of three years.

A good or service is transferred to a customer when, or as, the customer obtains control of that good or service. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized by measuring our progress in satisfying the performance obligation in a manner that depicts the transfer of the goods or services to the customer. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time that we determine the customer obtains control over the promised good or service. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for those promised goods or services (the "transaction price"). In determining the transaction price, we consider multiple factors, including the effects of variable consideration. Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. In determining when to include variable consideration in the transaction price, we consider the range of possible outcomes, the predictive value of our past experiences, the time period of when uncertainties expect to be resolved and the amount of consideration that is susceptible to factors outside of our influence, such as market volatility or the judgment and actions of third parties. The following provides detailed information on the recognition of our revenues from contracts with customers: Commissions and Other Fees. Jefferies Group earns commission revenue by executing, settling and clearing transactions for clients primarily in equity, equity-related and futures products. Trade execution and clearing services, when provided together, represent a single performance obligation as the services are not separately identifiable in the context of the contract. Commission revenues associated with combined trade execution and clearing services, as well as trade execution services on a standalone basis, are recognized at a point in time on trade-date. Commissions revenues are generally paid on settlement date and Jefferies Group records a receivable between trade-date and payment on settlement date. Jefferies Group permits institutional customers to allocate a portion of their gross commissions to pay for research products and other services provided by third parties. The amounts allocated for those purposes are commonly referred to as soft dollar arrangements. Jefferies Group acts as an agent in the soft dollar arrangements as the customer controls the use of the soft dollars and directs Jefferies Group's payments to third-party service providers on its behalf. Accordingly, amounts allocated to soft dollar arrangements are netted against commission revenues in our Consolidated Statements of Operations. Jefferies Group earns account advisory and distribution fees in connection with wealth management services. Account advisory fees are recognized over time using the time-elapsed method as Jefferies Group determined that the customer simultaneously receives and consumes the benefits of investment advisory services as they are provided. Account advisory fees may be paid in advance of a specified service period or in arrears at the end of the specified service period (e.g., quarterly). Account advisory fees paid in advance are initially deferred within Payables, expense accruals and other liabilities in the Consolidated Statements of Financial Condition. Distribution fees are variable and recognized when the uncertainties with respect to the amounts are resolved. Investment Banking. Jefferies Group provides its clients with a full range of capital markets and financial advisory services. Capital markets services include underwriting and placement agent services in both the equity and debt capital markets, including private equity placements, initial public offerings, follow-on offerings and equity-linked convertible securities transactions and structuring, underwriting and distributing public and private debt, including investment grade debt, high yield bonds, leveraged loans, municipal bonds and mortgage- and asset-backed securities. Underwriting and placement agent revenues are recognized at a point in time on trade-date, as the client obtains the control and benefit of the capital markets offering at that point. Costs associated with capital markets transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded, and are recorded on a gross basis within Selling, general and other expenses in the Consolidated Statements of Operations as Jefferies Group is acting as a principal in the arrangement. Any expenses reimbursed by its clients are recognized as Investment banking revenues. Revenues from financial advisory services primarily consist of fees generated in connection with merger, acquisition and restructuring transactions. Advisory fees from mergers and acquisitions engagements are recognized at a point in time when the related transaction is completed, as the performance obligation is to successfully broker a specific transaction. Fees received prior to the completion of the transaction are deferred within Payables, expense accruals and other liabilities in the Consolidated Statements of Financial Condition. Advisory fees from restructuring engagements are recognized over time using a time elapsed measure of progress as Jefferies Group's clients simultaneously receive and consume the benefits of those services as they are provided. A significant portion of the fees Jefferies Group receives for its advisory services are considered variable as they are contingent upon a future event (e.g., completion of a transaction or third-party emergence from bankruptcy) and are excluded from the transaction price until the uncertainty associated with the variable consideration is subsequently resolved, which is expected to occur upon achievement of the specified milestone. Payment for advisory services are generally due promptly upon completion of a specified milestone or, for retainer fees, periodically over the course of the engagement. Jefferies Group recognizes a receivable between the date of completion of the milestone and payment by the customer. Expenses associated with investment banking advisory engagements are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred. All investment banking advisory expenses are recognized within their respective expense category in the Consolidated Statements of Operations and any expenses reimbursed by Jefferies Group's clients are recognized as Investment banking revenues. Asset Management Fees. Jefferies Group earns management and performance fees, recorded in Other revenues, in connection with investment advisory services provided to various funds and accounts, which are satisfied over time and measured using a time elapsed measure of progress as the customer receives the benefits of the services evenly throughout the term of the contract. Management and performance fees are considered variable as they are subject to fluctuation (e.g., changes in assets under management, market performance) and/ or are contingent on a future event during the measurement period (e.g., meeting a specified benchmark) and are recognized only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. Management fees are generally based on month-end assets under management or an agreed upon notional amount and are included in the transaction price at the end of each month when the assets under management or notional amount is known. Performance fees are received when the return on assets under management for a specified performance period exceed certain benchmark returns, "high-water marks" or other performance targets. The performance period related to performance fees is annual or semi-annual. Accordingly, performance fee revenue will generally be recognized only at the end of the performance period to the extent that the benchmark return has been met. Manufacturing Revenues. Idaho Timber's primary business consists of the sale of lumber that is manufactured or remanufactured at one of its locations. Agreements with customers for these sales specify the type, quantity and price of products to be delivered as well as the delivery date and payment terms. The transaction price is fixed at the time of sale and revenue is generally recognized when the customer takes control of the product.

Information on Remaining Performance Obligations and Revenue Recognized from Past Performance We do not disclose information about remaining performance obligations pertaining to contracts that have an original expected duration of one year or less. The transaction price allocated to remaining unsatisfied or partially unsatisfied performance obligations with an original expected duration exceeding one year was not material at February 28, 2019 . Investment banking advisory fees that are contingent upon completion of a specific milestone and fees associated with certain distribution services are also excluded as the fees are considered variable and not included in the transaction price at February 28, 2019 . During the three months ended February 28, 2019 and March 31, 2018 , Jefferies Group recognized $14.7 million and $11.7 million , respectively, of revenue related to performance obligations satisfied (or partially satisfied) in previous periods, mainly due to resolving uncertainties in variable consideration that was constrained in prior periods. In addition, Jefferies Group recognized $4.9 million and $4.6 million , respectively, of revenues primarily associated with distribution services during the three months ended February 28, 2019 and March 31, 2018 , a portion of which relates to prior periods. Contract Balances The timing of revenue recognition may differ from the timing of payment by customers. We record a receivable when revenue is recognized prior to payment and it has an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, we record deferred revenue until the performance obligations are satisfied. We had receivables related to revenues from contracts with customers of $247.1 million and $250.6 million at February 28, 2019 and November 30, 2018 , respectively. We had no significant impairments related to these receivables during the three months ended February 28, 2019 and March 31, 2018 . Jefferies Group's deferred revenue primarily relates to retainer and milestone fees received in investment banking advisory engagements where the performance obligation has not yet been satisfied. Our deferred revenue, which primarily relates to Jefferies Group, was $11.5 million and $14.2 million at February 28, 2019 and November 30, 2018 , respectively, which are recorded as Payables, expense accruals and other liabilities in the Consolidated Statements of Financial Condition. During the three months ended February 28, 2019 , we recognized $7.6 million of deferred revenue from the balance at November 30, 2018 . During the three months ended March 31, 2018 , we recognized $4.9 million of deferred revenue from the balance at December 31, 2017 . Contract Costs Jefferies Group capitalizes costs to fulfill contracts associated with investment banking advisory engagements where the revenue is recognized at a point in time and the costs are determined to be recoverable. Capitalized costs to fulfill a contract are recognized at the point in time that the related revenue is recognized. At February 28, 2019 and November 30, 2018 , Jefferies Group's capitalized costs to fulfill a contract were $4.0 million and $4.7 million , respectively, which are recorded in Receivables in the Consolidated Statements of Financial Condition. For the three months ended February 28, 2019 and March 31, 2018 , Jefferies Group recognized expenses of $2.1 million and $2.4 million , respectively, related to costs to fulfill a contract that were capitalized as of the beginning of the period. There were no significant impairment charges recognized in relation to these capitalized costs during the three months ended February 28, 2019 and March 31, 2018 . At February 28, 2019 and November 30, 2018 , capitalized costs related to our other subsidiaries were not material.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The aggregate amount of gross unrecognized tax benefits related to uncertain tax positions at February 28, 2019 was $248.5 million (including $57.5 million for interest), of which $177.6 million related to Jefferies Group. The aggregate amount of gross unrecognized tax benefits related to uncertain tax positions at November 30, 2018 was $251.4 million (including $54.1 million for interest), of which $174.9 million related to Jefferies Group. If recognized, such amounts would lower our effective tax rate. We recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense. No material penalties were accrued for the three months ended February 28, 2019 and March 31, 2018 . The statute of limitations with respect to our federal income tax returns has expired for all years through 2014. We are currently under examination in a number of major tax jurisdictions. Prior to becoming a wholly-owned subsidiary, Jefferies Group filed a consolidated U.S. federal income tax return with its qualifying subsidiaries and was subject to income tax in various states, municipalities and foreign jurisdictions and Jefferies Group is also currently under examination in a number of major tax jurisdictions. We do not expect that resolution of these examinations will have a significant effect on our Consolidated Statements of Financial Condition, but could have a significant impact on the Consolidated Statements of Operations for the period in which resolution occurs. Regarding the new tax on global intangible low-taxed income ("GILTI"), which became applicable in fiscal 2019, we have made an accounting policy election to treat GILTI as a period cost if and when incurred. Our provision for income taxes for continuing operations for the three months ended February 28, 2019 was $2.3 million , representing an effective tax rate of 4.7% . Our provision for income taxes for the three months ended February 28, 2019 was reduced by $6.7 million related to completing our accounting for tax reform enacted in 2017, as permitted by Staff Accounting Bulletin No. 118, which was issued by the SEC staff on December 22, 2017. Our provision for income taxes for continuing operations for the three months ended March 31, 2018 was reduced by a $43.9 million benefit resulting from a reversal of our valuation allowance with respect to certain federal and state net operating loss carryforwards ("NOLs") which we now believe are more likely than not to be utilized before they expire.

Dividends declared on participating securities were not material during the three months ended February 28, 2019 and March 31, 2018 . Undistributed earnings are allocated to participating securities based upon their right to share in earnings if all earnings for the period had been distributed. For the three months ended February 28, 2019 , shares related to the mandatorily redeemable convertible preferred shares were not included in the computation of diluted per share amounts as the effect was antidilutive. The Board of Directors from time to time has authorized the repurchase of our common shares. In January 2019, the Board of Directors approved an additional $500.0 million share repurchase authorization. During the three months ended February 28, 2019 , we purchased a total of 9,600,000 of our common shares for an aggregate purchase price of $194.7 million under these authorizations. At February 28, 2019 , $305.3 million remained available for repurchase.

(2) At February 28, 2019 , $6,225.4 million within forward starting securities purchased under agreements to resell and $4,736.0 million within forward starting securities sold under agreements to repurchase settled within three business days. Equity Commitments. Equity commitments include commitments to invest in Jefferies Group's joint venture, Jefferies Finance, and commitments to invest in private equity funds and in Jefferies Capital Partners, LLC, the manager of the private equity funds, which consists of a team led by our President and a Director. At February 28, 2019 , Jefferies Group's outstanding commitments relating to Jefferies Capital Partners, LLC and its private equity funds were $17.9 million . See Note 9 for additional information regarding Jefferies Group's investment in Jefferies Finance. Additionally, as of February 28, 2019 , we have other equity commitments to invest up to $31.8 million in various other investments. Loan Commitments. From time to time Jefferies Group makes commitments to extend credit to investment banking and other clients in loan syndication, acquisition finance and securities transactions and to SPE sponsors in connection with the funding of CLO and other asset-backed transactions. These commitments and any related drawdowns of these facilities typically have fixed maturity dates and are contingent on certain representations, warranties and contractual conditions applicable to the borrower. At February 28, 2019 , Jefferies Group had $584.0 million of outstanding loan commitments to clients. Loan commitments outstanding at February 28, 2019 , also include Jefferies Group's portion of the outstanding secured revolving credit facility provided to Jefferies Finance to support loan underwritings by Jefferies Finance. At February 28, 2019 , none of Jefferies Group's $250.0 million commitment was funded. Underwriting Commitments . In connection with investment banking activities, Jefferies Group may from time to time provide underwriting commitments to its clients in connection with capital raising transactions. Forward Starting Reverse Repos and Repos. Jefferies Group enters into commitments to take possession of securities with agreements to resell on a forward starting basis and to sell securities with agreements to repurchase on a forward starting basis that are primarily secured by U.S. government and agency securities. Other Unfunded Commitments. Other unfunded commitments include obligations in the form of revolving notes to provide financing to asset-backed and CLO vehicles. Upon advancing funds, drawn amounts are collateralized by the assets of an entity. Contingencies We and our subsidiaries are parties to legal and regulatory proceedings that are considered to be either ordinary, routine litigation incidental to their business or not significant to our consolidated financial position. We and our subsidiaries are also involved, from time to time, in other exams, investigations and similar reviews (both formal and informal) by governmental and self-regulatory agencies regarding our businesses, certain of which may result in judgments, settlements, fines, penalties or other injunctions. We do not believe that any of these actions will have a significant adverse effect on our consolidated financial position or liquidity, but any amounts paid could be significant to results of operations for the period. Guarantees Derivative Contracts. Jefferies Group dealer activities cause it to make markets and trade in a variety of derivative instruments. Certain derivative contracts that Jefferies Group has entered into meet the accounting definition of a guarantee under GAAP, including credit default swaps, written foreign currency options and written equity put options. On certain of these contracts, such as written interest rate caps and foreign currency options, the maximum payout cannot be quantified since the increase in interest or foreign exchange rates are not contractually limited by the terms of the contract. As such, we have disclosed notional values as a measure of Jefferies Group's maximum potential payout under these contracts. The following table summarizes the notional amounts associated with Jefferies Group's derivative contracts meeting the definition of a guarantee under GAAP at February 28, 2019 (in millions): Expected Maturity Date Guarantee Type 2019 2020 2021 2023 2025 Notional/ Maximum Payout Derivative contracts – non-credit related $ 9,764.7 $ 2,569.7 $ 4,148.7 $ 281.8 $ 332.3 $ 17,097.2 Written derivative contracts – credit related — 32.4 1.5 61.0 — 94.9 Total derivative contracts $ 9,764.7 $ 2,602.1 $ 4,150.2 $ 342.8 $ 332.3 $ 17,192.1 The derivative contracts deemed to meet the definition of a guarantee under GAAP are before consideration of hedging transactions and only reflect a partial or "one-sided" component of any risk exposure. Written equity options and written credit default swaps are often executed in a strategy that is in tandem with long cash instruments (e.g., equity and debt securities). Jefferies Group substantially mitigates its exposure to market risk on these contracts through hedges, such as other derivative contracts and/or cash instruments, and Jefferies Group manages the risk associated with these contracts in the context of its overall risk management framework. Jefferies Group believes notional amounts overstate its expected payout and that fair value of these contracts is a more relevant measure of its obligations. The fair value of derivative contracts meeting the definition of a guarantee is approximately $161.7 million at February 28, 2019 . Berkadia. We have agreed to reimburse Berkshire Hathaway for up to one-half of any losses incurred under a $1.5 billion surety policy securing outstanding commercial paper issued by an affiliate of Berkadia. At February 28, 2019 , the aggregate amount of commercial paper outstanding was $1.47 billion . Other Guarantees. Jefferies Group is a member of various exchanges and clearing houses. In the normal course of business, Jefferies Group provides guarantees to securities clearing houses and exchanges. These guarantees generally are required under the standard membership agreements, such that members are required to guarantee the performance of other members. Additionally, if a member becomes unable to satisfy its obligations to the clearing house, other members would be required to meet these shortfalls. To mitigate these performance risks, the exchanges and clearing houses often require members to post collateral. Jefferies Group's obligations under such guarantees could exceed the collateral amounts posted. Jefferies Group's maximum potential liability under these arrangements cannot be quantified; however, the potential for Jefferies Group to be required to make payments under such guarantees is deemed remote. Accordingly, no liability has been recognized for these arrangements. Standby Letters of Credit. At February 28, 2019 , Jefferies Group provided guarantees to certain counterparties in the form of standby letters of credit totaling $37.1 million . Standby letters of credit commit Jefferies Group to make payment to the beneficiary if the guaranteed party fails to fulfill its obligation under a contractual arrangement with that beneficiary. Since commitments associated with these collateral instruments may expire unused, the amount shown does not necessarily reflect the actual future cash funding requirement. Other subsidiaries of ours have outstanding letters of credit aggregating $1.6 million at February 28, 2019 . Primarily all letters of credit expire within one year.

Net Capital Requirements [Abstract]
Net Capital Requirements	Net Capital Requirements Jefferies LLC operates as a broker-dealer registered with the SEC and member firms of the Financial Industry Regulatory Authority ("FINRA"). Jefferies LLC is subject to the SEC Uniform Net Capital Rule ("Rule 15c3-1"), which requires the maintenance of minimum net capital and has elected to calculate minimum capital requirements using the alternative method permitted by Rule 15c3-1 in calculating net capital. Jefferies LLC, as a dually-registered U.S. broker-dealer and futures commission merchant ("FCM"), is also subject to Rule 1.17 of the Commodity Futures Trading Commission ("CFTC"), which sets forth minimum financial requirements. The minimum net capital requirement in determining excess net capital for a dually-registered U.S. broker-dealer and FCM is equal to the greater of the requirement under Rule 15c3-1 or CFTC Rule 1.17. Jefferies LLC’s net capital and excess net capital at February 28, 2019 were $1,411.6 million and $1,303.2 million , respectively. FINRA is the designated examining authority for Jefferies Group's U.S. broker-dealer and the National Futures Association is the designated self-regulatory organization for Jefferies LLC as an FCM. Certain other U.S. and non-U.S. subsidiaries of Jefferies Group are subject to capital adequacy requirements as prescribed by the regulatory authorities in their respective jurisdictions, including Jefferies International Limited, which is authorized and regulated by the Financial Conduct Authority in the United Kingdom. The regulatory capital requirements referred to above may restrict our ability to withdraw capital from Jefferies Group's regulated subsidiaries. Some of our other consolidated subsidiaries also have credit agreements which may restrict the payment of cash dividends, or the ability to make loans or advances to the parent company.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On June 5, 2018, we sold 48% of National Beef to Marfrig for $907.7 million in cash, reducing our ownership in National Beef to 31% . Marfrig also acquired an additional 3% of National Beef from other equity owners and owns 51% of National Beef. Jefferies will continue to designate two board members and have a series of other rights in respect of our continuing equity interest, with a lockup period of five years and thereafter fair market value liquidity protections. As of the closing of the sale on June 5, 2018, we deconsolidated our investment in National Beef and account for our remaining interest under the equity method of accounting. The sale of National Beef meets the GAAP criteria to be classified as a discontinued operation as the sale represents a strategic shift that has a major effect in our operations and financial results. As such, we classified the results of National Beef prior to June 5, 2018 as a discontinued operation and reported those results in Income from discontinued operations, net of income tax provision in the Consolidated Statements of Operations. A summary of the results of discontinued operations for National Beef for the three months ended March 31, 2018 is as follows (in thousands): Revenues: Beef processing services $ 1,781,920 Interest income 68 Other 3,370 Total revenues 1,785,358 Expenses: Compensation and benefits 10,207 Cost of sales 1,670,776 Interest expense 2,109 Depreciation and amortization 25,519 Selling, general and other expenses 7,856 Total expenses 1,716,467 Income from discontinued operations before income taxes 68,891 Income tax provision 15,934 Income from discontinued operations, net of income tax provision $ 52,957 Net income attributable to the redeemable noncontrolling interests in the Consolidated Statements of Operations includes $14.5 million related to National Beef's noncontrolling interests for the three months ended March 31, 2018 . Pre-tax income from discontinued operations attributable to Jefferies Financial Group Inc. common shareholders was $54.4 million for the three months ended March 31, 2018 . As discussed above, we account for our retained 31% ownership of National Beef subsequent to the sale to Marfrig under the equity method. During the three months ended February 28, 2019 , we recorded $27.1 million in Income related to associated companies from our 31% ownership in National Beef and we received distributions from National Beef of $25.6 million .

Segment Reporting [Abstract]
Segment Information	Segment Information We are a diversified financial services company engaged in investment banking and capital markets, asset management and direct investing. In 2018, we made a number of strategic changes including the sale of 48% of National Beef and 100% of our interest in Garcadia. During the fourth quarter of 2018, we transferred to Jefferies Group our 50% interest in Berkadia and our LAM seed investments, thereby amalgamating our primary financial services operating businesses into one platform. Culminating with the fourth quarter reorganization, we began managing our business across three reportable operating segments consisting of Jefferies Group, Merchant Banking and Corporate. In connection with this change, we have reclassified the prior periods to conform to our current presentation. Jefferies Group is the largest independent U.S. headquartered global full-service integrated investment banking and securities firm. Merchant Banking consists of our various merchant banking businesses and investments, primarily including National Beef, Spectrum Brands, Linkem, Vitesse Energy Finance and JETX Energy, WeWork, HomeFed, Idaho Timber and FXCM. Our Merchant Banking businesses and investments also include Berkadia and our LAM seed investments, prior to their transfer to Jefferies Group in the fourth quarter of 2018, and Garcadia, prior to its sale in August 2018. Corporate assets primarily consist of financial instruments owned, the deferred tax asset (exclusive of Jefferies Group's deferred tax asset), cash and cash equivalents. Corporate revenues primarily include interest income. We do not allocate Corporate revenues or overhead expenses to the operating units As discussed further in Note 24, on June 5, 2018, we sold 48% of National Beef to Marfrig and deconsolidated our investment in National Beef. Results prior to June 5, 2018 are classified in discontinued operations and are not included in the table below. Our retained 31% interest in National Beef is accounted for under the equity method, and results subsequent to the June 5, 2018 closing are included in Merchant Banking in the table below.

Accounting Policies [Abstract]
Revenue Recognition Policies	Revenue from contracts with customers is recognized when, or as, we satisfy our performance obligations by transferring the promised goods or services to the customers. A good or service is transferred to a customer when, or as, the customer obtains control of that good or service. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized by measuring our progress in satisfying the performance obligation in a manner that depicts the transfer of the goods or services to the customer. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time that we determine the customer obtains control over the promised good or service. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for those promised goods or services (the "transaction price"). In determining the transaction price, we consider multiple factors, including the effects of variable consideration. Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. In determining when to include variable consideration in the transaction price, we consider the range of possible outcomes, the predictive value of our past experiences, the time period of when uncertainties expect to be resolved and the amount of consideration that is susceptible to factors outside of our influence, such as market volatility or the judgment and actions of third parties. The following provides detailed information on the recognition of our revenues from contracts with customers: Commissions and Other Fees. Jefferies Group earns commission revenue by executing, settling and clearing transactions for clients primarily in equity, equity-related and futures products. Trade execution and clearing services, when provided together, represent a single performance obligation as the services are not separately identifiable in the context of the contract. Commission revenues associated with combined trade execution and clearing services, as well as trade execution services on a standalone basis, are recognized at a point in time on trade-date. Commissions revenues are generally paid on settlement date and Jefferies Group records a receivable between trade-date and payment on settlement date. Jefferies Group permits institutional customers to allocate a portion of their gross commissions to pay for research products and other services provided by third parties. The amounts allocated for those purposes are commonly referred to as soft dollar arrangements. Jefferies Group acts as an agent in the soft dollar arrangements as the customer controls the use of the soft dollars and directs Jefferies Group's payments to third-party service providers on its behalf. Accordingly, amounts allocated to soft dollar arrangements are netted against commission revenues in our Consolidated Statements of Operations. Jefferies Group earns account advisory and distribution fees in connection with wealth management services. Account advisory fees are recognized over time using the time-elapsed method as Jefferies Group determined that the customer simultaneously receives and consumes the benefits of investment advisory services as they are provided. Account advisory fees may be paid in advance of a specified service period or in arrears at the end of the specified service period (e.g., quarterly). Account advisory fees paid in advance are initially deferred within Payables, expense accruals and other liabilities in the Consolidated Statements of Financial Condition. Distribution fees are variable and recognized when the uncertainties with respect to the amounts are resolved. Investment Banking. Jefferies Group provides its clients with a full range of capital markets and financial advisory services. Capital markets services include underwriting and placement agent services in both the equity and debt capital markets, including private equity placements, initial public offerings, follow-on offerings and equity-linked convertible securities transactions and structuring, underwriting and distributing public and private debt, including investment grade debt, high yield bonds, leveraged loans, municipal bonds and mortgage- and asset-backed securities. Underwriting and placement agent revenues are recognized at a point in time on trade-date, as the client obtains the control and benefit of the capital markets offering at that point. Costs associated with capital markets transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded, and are recorded on a gross basis within Selling, general and other expenses in the Consolidated Statements of Operations as Jefferies Group is acting as a principal in the arrangement. Any expenses reimbursed by its clients are recognized as Investment banking revenues. Revenues from financial advisory services primarily consist of fees generated in connection with merger, acquisition and restructuring transactions. Advisory fees from mergers and acquisitions engagements are recognized at a point in time when the related transaction is completed, as the performance obligation is to successfully broker a specific transaction. Fees received prior to the completion of the transaction are deferred within Payables, expense accruals and other liabilities in the Consolidated Statements of Financial Condition. Advisory fees from restructuring engagements are recognized over time using a time elapsed measure of progress as Jefferies Group's clients simultaneously receive and consume the benefits of those services as they are provided. A significant portion of the fees Jefferies Group receives for its advisory services are considered variable as they are contingent upon a future event (e.g., completion of a transaction or third-party emergence from bankruptcy) and are excluded from the transaction price until the uncertainty associated with the variable consideration is subsequently resolved, which is expected to occur upon achievement of the specified milestone. Payment for advisory services are generally due promptly upon completion of a specified milestone or, for retainer fees, periodically over the course of the engagement. Jefferies Group recognizes a receivable between the date of completion of the milestone and payment by the customer. Expenses associated with investment banking advisory engagements are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred. All investment banking advisory expenses are recognized within their respective expense category in the Consolidated Statements of Operations and any expenses reimbursed by Jefferies Group's clients are recognized as Investment banking revenues. Asset Management Fees. Jefferies Group earns management and performance fees, recorded in Other revenues, in connection with investment advisory services provided to various funds and accounts, which are satisfied over time and measured using a time elapsed measure of progress as the customer receives the benefits of the services evenly throughout the term of the contract. Management and performance fees are considered variable as they are subject to fluctuation (e.g., changes in assets under management, market performance) and/ or are contingent on a future event during the measurement period (e.g., meeting a specified benchmark) and are recognized only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. Management fees are generally based on month-end assets under management or an agreed upon notional amount and are included in the transaction price at the end of each month when the assets under management or notional amount is known. Performance fees are received when the return on assets under management for a specified performance period exceed certain benchmark returns, "high-water marks" or other performance targets. The performance period related to performance fees is annual or semi-annual. Accordingly, performance fee revenue will generally be recognized only at the end of the performance period to the extent that the benchmark return has been met. Manufacturing Revenues. Idaho Timber's primary business consists of the sale of lumber that is manufactured or remanufactured at one of its locations. Agreements with customers for these sales specify the type, quantity and price of products to be delivered as well as the delivery date and payment terms. The transaction price is fixed at the time of sale and revenue is generally recognized when the customer takes control of the product.
Accounting Developments	Accounting Developments - Accounting Standards to be Adopted in Future Periods Leases. In February 2016, the Financial Accounting Standards Board ("FASB") issued new guidance that affects the accounting and disclosure requirements for leases. The FASB requires the recognition of all leases that are longer than one year onto the balance sheet, which will result in the recognition of a right of use asset and a corresponding lease liability. The right of use asset and lease liability will be measured initially using the present value of the remaining rental payments. A significant portion of the population of contracts that will be subject to recognition on our Consolidated Statements of Financial Condition have been identified; however, their initial measurement still remains under evaluation. We are currently modifying certain of our lease accounting systems to enable us to comply with the accounting requirements of this guidance. In July 2018, the FASB issued additional guidance on leases which allows an entity to recognize a cumulative-effect adjustment to the opening balance of retained earnings upon adoption. The guidance is effective for annual and interim periods beginning after December 15, 2018. We plan on adopting the lease standard in the first quarter of fiscal 2020 with a cumulative-effect adjustment to opening retained earnings in the period of adoption. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Financial Instruments - Credit Losses. In June 2016, the FASB issued new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. The guidance is effective in the first quarter of fiscal 2021. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Goodwill. In January 2017, the FASB issued new guidance for simplifying goodwill impairment testing. The guidance is effective in the first quarter of fiscal 2021. We do not believe the new guidance will have a material impact on our consolidated financial statements. Derivatives and Hedging. In August 2017, the FASB issued new guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The guidance is effective in the first quarter of fiscal 2020. We do not believe the new guidance will have a material impact on our consolidated financial statements. Defined Benefit Plans. In August 2018, the FASB issued new guidance to improve the effectiveness of disclosure requirements on defined benefit pension plans and other post-retirement plans. The guidance is effective in the first quarter of fiscal 2021. We do not believe the new guidance will have a material impact on our consolidated financial statements. Internal-Use Software. In August 2018, the FASB issued new guidance which amends the definition of a hosting arrangement and requires that the customer in a hosting arrangement that is a service contract capitalize certain implementation costs as if the arrangement was an internal-use software project. The guidance is effective in the first quarter of fiscal 2021. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Consolidation. In October 2018, the FASB issued new guidance which requires indirect interests held through related parties under common control arrangements be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. The guidance is effective in the first quarter of fiscal 2021. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

Quantitative Information About Significant Unobservable Inputs Used In Level 3 Fair Value Measurements	The tables below present information on the valuation techniques, significant unobservable inputs and their ranges for our financial assets and liabilities, subject to threshold levels related to the market value of the positions held, measured at fair value on a recurring basis with a significant Level 3 balance. The range of unobservable inputs could differ significantly across different firms given the range of products across different firms in the financial services sector. The inputs are not representative of the inputs that could have been used in the valuation of any one financial instrument (i.e., the input used for valuing one financial instrument within a particular class of financial instruments may not be appropriate for valuing other financial instruments within that given class). Additionally, the ranges of inputs presented below should not be construed to represent uncertainty regarding the fair values of our financial instruments; rather, the range of inputs is reflective of the differences in the underlying characteristics of the financial instruments in each category. For certain categories, we have provided a weighted average of the inputs allocated based on the fair values of the financial instruments comprising the category. We do not believe that the range or weighted average of the inputs is indicative of the reasonableness of uncertainty of our Level 3 fair values. The range and weighted average are driven by the individual financial instruments within each category and their relative distribution in the population. The disclosed inputs when compared with the inputs as disclosed in other periods should not be expected to necessarily be indicative of changes in our estimates of unobservable inputs for a particular financial instrument as the population of financial instruments comprising the category will vary from period to period based on purchases and sales of financial instruments during the period as well as transfers into and out of Level 3 each period.
