In order to compete effectively and continue to provide best in classbest-in-class service to our clients, we must attract, retain, and motivate qualified professionals. Our core workforce is predominately composed of employees in roles such as investment bankers, salespeople,sales, trading, professionals, research professionals and other revenue producing or specializedsupport personnel. During 2021, within Jefferies Group, we hired over 1,2002023, our headcount increased by 2,183 related primarily to hiring of professionals globally as well as the addition of professionals as a result of our acquisitions of Stratos and OpNet. While our investment is largely in Investment Banking, there has also been meaningful additional investments in Equities, Fixed Income, Research, Support and Alternative Asset Management. Within our Investment Banking and Capital Markets segment, our voluntary turnover rate was approximately 12.2%7.9%, which makes our overall retention rate very high in our view. We believe our culture, our effort to maintain a meritocracy in terms of opportunity and compensation, and our continued evolution and growth contribute to our success in attracting and retaining strong talent.

We alsooffer two targeted recruiting programs aimed at diversifying the pipeline of our lateral hires, including a career relaunch program (jReturns), aimed at those who have taken a break from the workforce, and a job switch program aimed at recruiting individuals who are interested in changing careers into Equity Research. Both programs yielded full-time hires in 2023.

We value continued training and development for all employees at the firm.employees. We seek to equip our people at all stages in their careers with the tools necessary to become thoughtful and effective leaders. In 2021, we introduced a number of additionalWe offer customized, year-long training curriculums across all divisions and title levels globally, focused on upskilling, professional development, programsand management best practices. We also offer mentoring initiatives, including our inauguralfirmwide Cross-Divisional Mentoring Program, Career Advisory Program, and New Hire Buddy Program. Our Women in Leadership Series a program focused on providingprovides learning and development, and networking opportunities to position our female leaders for success. We also launched asuccess, and our jWIN Career Catalyst Program offers development and networking opportunities to VP promotes. Our leadership development program, sponsored by our Jefferies Black & Latino Network (J-NOBLE) and Jefferies Ethnic Minority Society (JEMS) that is aimed at providing professional development and career advancement training to participants. Additionally, we offered customized training courses centered around Project Management, Communicating with Clarity and Impact, Managing in the New Normal, Finding and Using Your Strengths and Effective Sales Training for our employees.

In addition to training and development programs, we have beencontinue to be incredibly focused on the mental and physical well-being of our employees. We host frequent global wellness webinars and offerled my mental health experts, provide confidential, 1:1 wellness counseling. To support our employee'sand nutritional counseling and offer a variety of tailored wellness content for “Mental Health Awareness Month” in May and “World Mental Health Day” in October. The events for these two initiatives include training sessions with world-class psychologists and nutritionists on healthy eating habits, managing stress and well-being, emotional regulation, mindfulness and physical well-being, we host virtual fitness classes andinitiatives such as group classes. Throughout the year, we’ve also conducted small-group wellness discussion surrounding topical events. We also have partnered with a fitness appapplication our employees can utilize.

The foundation of our culture is our approach to employee engagement, diversity, equity and inclusion (“DE&I”), which is summed up in our Corporate Social Responsibility Principle: Respect People. We embrace diversity, and inclusion, which we believe fosters creativity, innovation and thought leadership through the infusion of new ideas and perspectives. We have implemented a number of policies and measures focused on non-discrimination, sexual harassment prevention, health and safety, and training and education. We have strong internal partnerships withengaging in eight global Employee Resource Groups that are fostering a diverse, inclusive workplace. Our Diversity Council, chairedco-sponsored by Rich Handler, our CEO, and Brian Friedman, our President, gives our Employee Resource Groups a platform to come together and discuss best practices, as well as collaborate on firmwide diversity initiatives.

We encourage you to review our ESG Report (located on our website) for more detailed information regarding our human capital programs and initiatives. Nothing on our website, including ourthe ESG Report or sections thereof is deemed incorporated by reference into this Report. In addition, for discussion of the risks relating to our ability to attract, develop and retain highly skilled and productive employees, see "Part“Part 1. Item 1A. Risk Factors."”

Our benefits are designed to attract, support and retain employees by providing employees and their spouses, partners and families with health and wellness programs (medical, dental, vision and behavioral), retirement wealth accumulation, paid time off, income replacement (paid sick and disability leaves and life insurance) and family orientedfamily-oriented benefits (parental leaves and child care assistance). In 2022, we rolled out a new benefit for employees to support inclusive fertility health and family-forming benefits to all employees. This year, we continued to broaden our inclusive benefits offering by adding menopause support. We also endeavor to provide location specific health club, transportation and employee discounts.

The firm is committed to giving back to our communities. In 2021,2023, we donated $13.2$17.6 million to approximately 175447 organizations across two "Doing Good"“Doing Good” trading days.days and a number of other Jefferies-supported charitable initiatives. Additionally, through our Employee Resource Groups, employees have created lasting partnerships by volunteering time to support several of these charitable partners.

All aspects of our business are intensely competitive. We compete primarily with large global bank holding companies that engage in investment banking and capital markets activities but also with other broker-dealers, asset managersas one of their lines of business and boutique investment banking firms. The large global bank holding companiesthat have substantially greater capital and resources than we do. We also compete against other broker-dealers, asset managers and boutique firms. We believe that the principal factors affectingdriving our competitive standingcompetitiveness include the quality, experience and skills of our professionals, the depth of our relationships, the breadth of our service offerings, our ability to provide differentiated insights to our clients that lead to better business outcomes; to attract, retain and develop skilled professionals; to deliver consistently our integrated capabilities,a competitive breadth of high-quality service offerings; and ourto maintain a flat, nimble and entrepreneurial culture tenacitybuilt on immediacy and commitment to serve our clients.

In addition, certain states, have proposed or adopted measures that would make broker-dealers, sales agents and investment advisors and their representatives subject to a fiduciary duty when providing products and services to customers. The SEC did not indicate an intent to pre-empt state regulation in this area, and some of the state proposals would allow for a private right of action. Since our Wealth Management division makes recommendations to retail customers, it is required to comply with the obligations imposed under Reg BI and applicable state laws.

SEC registered broker-dealers that also register with the SEC as security-based swap dealers engaging in principal transactions of security-based swaps ("SBS"(“SBS”) are subject to rules regarding capital, segregation and margin requirements. The SEC rules establish similar standards for an entity registering as a standalone SBS dealer. The CFTC and NFA have also adopted similar swap dealer capital rules. Under the rules there is a minimum net capital requirement for, among others, an entity that acts as a dealer in SBS or swaps, which is the greater of $20 million or 2% (that the SEC could, in the future, increase up to 4% or 8%) of a risk margin amount. The risk margin amount for the SEC means the sum of (i) the total initial margin required to be maintained by the SEC-registered SBS dealer at each clearing houseclearinghouse with respect to SBS or swap transactions cleared for SBS or swap customers and (ii) the total initial margin amount calculated by the SEC-registered SBS dealer with respect to non-cleared SBS and swaps under the SEC rules. The risk margin amount for the CFTC means the total initial margin amount calculated by the CFTC-registered swap dealer with respect to non-cleared SBS and swaps under the CFTC rules.

Jefferies Financial Services, Inc. ("JFSI"(“JFSI”), one of Jefferies Group'sour subsidiaries, is registered with the CFTC as a swap dealer and registered with the SEC as an SBS. As of late 2021, JFSISBS dealer and is now required to comply with the SEC and CFTC capital rules for SBS dealers and swap dealers, respectively. Further, subsequent to year end, on December 16, 2021, JFSI was approved by the SEC as an OTC derivatives dealer, andJFSI is subject to compliance with the SEC'sSEC’s net capital requirements.

Under the Exchange Act, state securities regulators are not permitted to impose capital, margin, custody, financial responsibility, making and keeping records, bonding, or financial or operational reporting requirements on registered broker-dealers that differ from, or are in addition to, the requirements in those areas established under the Exchange Act, including the rules and regulations promulgated thereunder.

For additional information see Item 1A. Risk Factors.Factors - “Legislation and regulation may significantly affect our business.”

Jefferies Financial Group LLCInc. is not subject to any regulatory capital rules.

See Net Capital within Item 7. Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations, and Note 23 to our consolidated financial statements25, Regulatory Requirements in this Annual Report on Form 10-K for additional discussion of net capital calculations.

In the normal course of our businesses, we are involved in the execution, settlement and financing of various customer and principal securities and derivative transactions. These activities are transacted on a cash, margin or delivery-versus-payment basis and are subject to the risk of counterparty or customer nonperformance. Even when transactions are collateralized by the underlying security or other securities, we still face the risks associated with changes in the market value of the collateral through settlement date or during the time when margin is extended and collateral has not been secured or the counterparty defaults before collateral or margin can be adjusted. We may also incur credit risk in our derivative transactions to the extent such transactions result in uncollateralized credit exposure to our counterparties.

We seek to control the risk associated with these transactions by establishing and monitoring credit limits and by monitoring collateral and transaction levels daily. We may require counterparties to deposit additional collateral or return collateral pledged. In certain circumstances, we may, under industry regulations, purchase the underlying securities in the market and seek reimbursement for any losses from the counterparty. However, there can be no assurances that our risk controls will be successful.

Market risk generally represents the risk that values of assets and liabilities or revenues will be adversely affected by changes in market conditions. Market risk is inherent in the financial instruments associated with our operations and activities, including trading account assets and liabilities, loans, securities, short-term borrowings, corporate debt, and derivatives. Market conditions that change from time to time, thereby exposing us to market risk, include fluctuations in interest rates, equity prices, relative exchange rates, and price deterioration or changes in value due to changes in market perception or actual credit quality of an issuer.

In addition, disruptions in the liquidity or transparency of the financial markets may result in our inability to sell, syndicate, or realize the value of security positions, thereby leading to increased concentrations. The inability to reduce our positions in specific securities may not only increase the market and credit risks associated with such positions, but also increase capital requirements, which could have an adverse effect on our business, results of operations, financial condition, and liquidity.

A considerable portion of our revenues is derived from trading in which we act as principal. We may incur trading losses relating to the purchase, sale or short sale of fixed income, high yield, international, convertible, and equity securities, loans, derivative contracts and commodities for our own account. In any period, we may experience losses on our inventory positions as a result of the level and volatility of equity, fixed income and commodity prices (including oil prices), lack of trading volume and illiquidity. From time to time, we may engage in a large block trade in a single security or maintain large position concentrations in a single security, securities of a single issuer, securities of issuers engaged in a specific industry, or securities from issuers located in a particular country or region. In general, because our inventory is marked to market on a daily basis, any adverse price movement in these securities could result in a reduction of our revenues and profits. In addition, we may engage in hedging transactions that if not successful, could result in losses. Increased market volatility may also impact our revenues as transaction activity in our investment banking and capital markets sales and trading businesses can be negatively impacted in a volatile market environment.

We continue to work towards reducing our exposure to IBOR-referencing contracts, including derivatives, securities, and other financial products, to meet the industry milestones and recommendations published by National Working Groups ("NWG"(“NWG”), including the Alternative Reference Rates Committee (the "ARRC"“ARRC”) in the U.S.

Uncertainty regarding IBORs and the taking of discretionary actions or negotiation of rate fallback provisions could result in pricing volatility, loss of market share in certain products, adverse tax or accounting impacts, compliance, legal and operational

As a number of industries, primarily in the financial services industry. Our business, financial condition and results of operations are dependent on these investments. Any material adverse change in one of our businesses or investments, or in a particular industry in whichholding company, we operate or invest, may cause material adverse changes to our business, financial condition and results of operations. The more capital we devote to a particular investment or industry may increase the risk that such investment could significantly impact our financial condition and results of operations, possibly in a material adverse way.

From time to time we may invest in securities that are subject to restrictions which prohibit us from selling the subject securities for a period of time. Such agreements may limit our ability to generate liquidity quickly through the disposition of the underlying investment while the agreement is effective.

Climate change may cause extreme weather events that disrupt operations at one or more of our or our customer’s or client’s locations, which may negatively affect our ability to service and interact with our clients, and also may adversely affect the value of certain of our investments, including our real estate and oil and gas investments. Climate change, as well as uncertainties related to the transition to a lower carbon dependent economy, may also have a negative impact on the financial condition of our clients, which may decrease revenues from those clients and increase the credit risk associated with loans and other credit exposures to those clients. Additionally, our reputation and client relationships may be damaged as a result of our involvement, or our clients'clients’ involvement, in certain industries or projects associated with causing or exacerbating climate change, as well as any decisions we make to continue to conduct or change our activities in response to considerations relating to climate change.

New regulations or guidance relating to climate change and the transition to a lower carbon dependent economy, as well as the perspectives of shareholders, employees and other stakeholders regarding climate change, may affect whether and on what terms and conditions we engage in certain activities or offer certain products.products, as well as impact our business reputation and efforts to recruit and retain employees and customers.

Economic and market conditions have had, and will continue to have, a direct and material impact on our results of operations and financial condition because performance in the financial services industry is heavily influenced by the overall strength of general economic conditions and financial market activity.

Our investment banking revenue, in the form of advisory services and underwriting, is directly related to general economic conditions and corresponding financial market activity. When the outlook for such economic conditions is uncertain or negative, financial market activity generally tends to decrease, which reduces our investment banking revenues. Reduced expectations of U.S. economic growth or a decline in the global economic outlook could cause financial market activity to decrease and negatively affect our investment banking revenues.

In addition, global economic conditions and global financial markets remain vulnerable to the potential risks posed by certain events, which could include, among other things, level and volatility of interest rates, availability and market conditions of financing, economic growth or its sustainability, unforeseen changes to gross domestic product, inflation, energy prices, fluctuations or other changes in both debt and equity capital markets and currencies, political and financial uncertainty in the U.S.United States and the EU,European Union, ongoing concern about Asia'sAsia’s economies, global supply disruptions, complications involving terrorism and armed conflicts around the world (including the conflict between Russia and Ukraine, and Hamas and Israel, or other challenges to global trade or travel, such as those that have occurred due to the COVID-19 pandemic. More generally, because our business is closely correlated to the general economic outlook, a significant deterioration in that outlook or realization of certain events would likely have an immediate and significant negative impact on our business and overall results of operations.

Global or regional changes in the financial markets or economic and political conditions that may be specific to the industriescould adversely affect our business in which our businesses and investments operate, as well as a general economic slowdown, prolonged recession or other market downturn or disruption. Adverse impacts may includemany ways, including the following:

Maintaining our reputation is critical to our attracting and maintaining customers, investors and employees. If we fail to deal with, or appear to fail to deal with, various issues that may give rise to reputational risk, we could significantly harm our business prospects. These issues include, but are not limited to, any of the risks discussed in this Item 1A, appropriately dealing with potential conflicts of interest, legal and regulatory requirements, ethical issues, money-laundering, cybersecurity and privacy, record keeping, sales and trading practices, failure to sell securities we have underwritten at the anticipated price levels, and the proper identification of the legal, reputational, credit, liquidity and market risks inherent in our products. A failure to deliver appropriate standards of service and quality, or a failure or perceived failure to treat customers and clients fairly, can result in customer dissatisfaction, litigation and heightened regulatory scrutiny, all of which can lead to lost revenue, higher operating costs and harm to our reputation. Further, negative publicity regarding us, whether or not true, may also result in harm to our prospects. Our operations in the past have been impacted as some clients either ceased doing business or temporarily slowed down the level of business they do, thereby decreasing our revenue. There is no assurance that we will be able to successfully reverse the negative impact of allegations and rumors in the future and our potential failure to do so could have a material adverse effect on our business, financial condition and liquidity.

We seek to monitor and control our risk exposure. Our risk management processes and procedures are designed to limit our and certain of our subsidiaries' exposure to acceptable levels as we conduct our businesses.business. We and certain of our subsidiaries apply a comprehensive frameworksframework of limits on a variety of key metrics to constrain the risk profile of our business activities. These limits reflect our risk tolerances for business activity. The frameworks may includeOur framework includes inventory position and exposure limits on a gross and net basis, scenario analysis and stress tests, Value-at-Risk, sensitivities, exposure concentrations, aged inventory, amount of Level 3 assets, counterparty exposure, leverage, cash capital and performance analysis. See Management’s Discussion and Analysis of Financial Condition and Results of Operations - Risk Management within Part II. Item 7. of this Annual Report on Form 10-K for additional discussion. While we and certain of our subsidiaries employ various risk monitoring and risk mitigation techniques, those techniques and the judgments that accompany their application, including risk tolerance determinations, cannot anticipate every economic and financial outcome or the specifics and timing of such outcomes. As a result, we may incur losses notwithstanding our risk management processes and procedures.

Our ability to develop and retain our clients depends on the reputation, judgment, business generation capabilities and skills of our professionals. To compete effectively, we must attract, retain and motivate qualified professionals, including successful financial advisors, investment bankers, sales and trading professionals, research professionals, portfolio managers and other revenue producing or specialized personnel, in addition to qualified, successful personnel in functional, non-revenue producing roles. Competitive pressures we experience with respect to employees could have an adverse effect on our business, results of operations, financial condition and liquidity.

Turnover in the financial services industry is high. The cost of retaining skilled professionals in the financial services industry has escalated considerably. Financial industry employers are increasingly offering guaranteed contracts, upfront payments, and increased compensation. These can be important factors in a current employee'semployee’s decision to leave us as well as in a prospective employee'semployee’s decision to join us. As competition for skilled professionals in the industry remains intense, we may have to devote significant resources to attracting and retaining qualified personnel.

If we were to lose the services of certain of our professionals, we may not be able to retain valuable relationships and some of our clients could choose to use the services of a competitor instead of our services. If we are unable to retain our professionals or recruit additional professionals, our reputation, business, results of operations and financial condition will be adversely affected. Further, new business initiatives and efforts to expand existing businesses frequently require that we incur compensation and benefits expense before generating additional revenues.

Moreover, companies in our industriesindustry whose employees accept positions with competitors often claim that those competitors have engaged in unfair hiring practices. We may be subject to such claims in the future as we seek to hire qualified personnel who have worked for our competitors. Some of these claims may result in material litigation. We could incur substantial costs in defending against these claims, regardless of their merits. Such claims could also discourage potential employees who work for our competitors from joining us.

Our businesses are highly dependent on our ability to process, on a daily basis, a large number of transactions across numerous and diverse markets in many currencies, and the transactions we process have become increasingly complex. If any of our financial, accounting or other data processing systems do not operate properly, or are disabled, or if there are other shortcomings or failures in our internal processes, people or systems, we could suffer an impairment to our liquidity, financial loss, a disruption of our businesses, liability to clients, regulatory intervention or reputational damage. These systems may fail to operate properly or become disabled as a result of events that are wholly or partially beyond our control, including a disruption of electrical or communications services or our inability to occupy one or more of our buildings. The inability of our systems to accommodate an increasing volume and complexity of transactions could also constrain our ability to expand our businesses.

Certain of our financial and other data processing systems rely on access to and the functionality of operating systems maintained by third-parties. If the accounting, trading or other data processing systems on which we are dependent are unable to meet increasingly demanding standards for processing and security or, if they fail or have other significant shortcomings, we could be adversely affected. Such consequences may include our inability to effect transactions and manage our exposure to risk.

Our operations rely heavily on the secure processing, storage and transmission of financial, personal and other information in our computer systems and networks. In recent years, there have been several highly publicized incidents involving financial services companies reporting the unauthorized disclosure of client or other confidential information, as well as cyber attacks involving theft, dissemination and destruction of corporate information or other assets, which in some cases occurred as a result of failure to follow procedures by employees or contractors or as a result of actions by third-parties. Cyber attacks can originate from a variety of sources, including third-parties affiliated with foreign governments, organized crime or terrorist organizations, and malicious individuals both outside and inside a targeted company.company, including through use of relatively new artificial intelligence tools or methods. Retaliatory acts by Russia, Hamas or their allies in response to economic sanctions or other measures taken by the global community arising from the Russia-Ukraine and Hamas-Israel conflicts could result in an increased number and/or severity of cyber attacks. Malicious actors may also attempt to compromise or induce our induce employees, clients or other users of our systems to disclose sensitive information or provide access to our data, and these types of risks may be difficult to detect or prevent.

We also rely on numerous third-party service providers to conduct other aspects of our business operations, and we face similar risks relating to them. While we evaluate the information security programs and defenses of third-party vendors, we cannot be

certain that our reviews and oversight will identify all potential information security weaknesses, or that our vendors'vendors’ information security protocols are or will be sufficient to withstand or adequately respond to a cyber attack, cybersecurity incident, or other information security breach. In addition, in order to access our products and services, or trade with us, our customers and counterparties may use networks, computers and other devices that are beyond our security control systems and processes.

Notwithstanding the precautions we take, if a cyber attack, cybersecurity incident, or other information security breach were to occur, this could jeopardize the information we confidentially maintain, or otherwise cause interruptions in our operations or those of our clients and counterparties, exposing us to liability. As attempted attacks continue to evolve in scope and sophistication, we may be required to expend substantial additional resources to modify or enhance our reasonable security measures, to investigate and remediate vulnerabilities or other exposures or to communicate about cyber attacks, cybersecurity incidents, or other information security breaches to our customers, partners, third-party service providers, and counterparties. Though we have insurance against some cyber risks and attacks, we may be subject to litigation and financial losses that exceed our insurance policy limits or are not covered under any of our current insurance policies. A technological breakdown could also interfere with our ability to comply with financial reporting and other regulatory requirements, exposing us to potential disciplinary action by regulators. Successful cyber attacks, cybersecurity incidents, or other information security breaches at other large financial institutions or other market participants, whether or not we are affected, could lead to a general loss of customer confidence in financial institutions that could negatively affect us, including harming the market perception of the effectiveness of our reasonable security measures or the financial system in general, which could result in a loss of business.

Further, in light of the high volume of transactions we process, the large number of our clients, partners and counterparties, and the increasing sophistication of malicious actors that may employ increasingly sophisticated methods such as new artificial intelligence tools, a cyber attack, cybersecurity incident, or other information security breach could occur and persist for an extended period of time without detection. We expect that any investigation of a cyber attack, cybersecurity incident, or other information security breach would take substantial amounts of time and resources, and that there may be extensive delays before we obtain full and reliable information. During such time we would not necessarily know the extent of the harm caused by the cyber attack, cybersecurity incident, or other information security breach or how best to remediate it, and certain errors or actions could be repeated or compounded before they are discovered and remediated. All of these factors could further increase the costs and consequences of such a cyber attack or cybersecurity incident. In providing services to clients, we manage, utilize and store sensitive or confidential client or employee data, including personal data. As a result, we are subject to numerous laws and regulations designed to protect this information, such as U.S. and non-U.S. federal and state laws governing privacy and cybersecurity. If any person, including any of our associates, negligently disregards or intentionally breaches our established controls with respect to client or employee data, or otherwise mismanages or misappropriates such data, we could be subject to significant monetary damages, regulatory enforcement actions, fines and/or criminal prosecution. In addition, unauthorized disclosure of sensitive or confidential client or employee data, whether through system compromise or failure, employee negligence, fraud or misappropriation, could damage our reputation and cause us to lose clients and related revenue. Depending on the circumstances giving rise to the information security breach, this liability may not be subject to a contractual limit or an exclusion of consequential or indirect damages.

There is a risk that our employees could engage in misconduct that adversely affects our business. For example, our business often requires that we deal with confidential matters of great significance to our clients. If our employees were to improperly use or disclose confidential information provided by our clients, we could be subject to regulatory sanctions and suffer serious harm to our reputation, financial position, current client relationships and ability to attract future clients. We are also subject to a number of obligations and standards arising from our asset management business and our authority over the assets managed by our asset management business. In addition, our financial advisors may act in a fiduciary capacity, providing financial planning, investment advice, and discretionary asset management. The violation of these obligations and standards by any of our employees would adversely affect our clients and us. It is not always possible to deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective against certain misconduct, including conduct which is difficult to detect. The occurrence of significant employee misconduct could have a

We cannot be certain that we will be able to insure all risks that we desire to insure economically or that all of our insurers or reinsurers will be financially viable if we make a claim. If an uninsured loss or a loss in excess of insured limits should occur, or if we are required to pay a deductible for an insured loss, results of operations could be adversely affected.

Any future acquisitions or dispositions may result in significant changes in the composition of our assets and liabilities, as well as our business mix and prospects. Consequently, our financial condition, results of operations and the trading price of our securities may be affected by factors different from those affecting our financial condition, results of operations and trading price at the present time.

Many factors, most of which are outside of our control, can affect Jefferies Finance'sFinance’s business, including adverse investment banking and capital market conditions leading to a decline of syndicate loans, inability of borrowers to repay commitments, adverse changes to a borrower'sborrower’s credit worthiness, and other factors that directly and indirectly effect the results of operations, and consequently may adversely affect our results of operations or financial condition.

Many factors, most of which are outside of our control, can affect Berkadia'sBerkadia’s business, including loan losses in excess of reserves, a change in the relationships with U.S. Government-Sponsored Enterprises or federal agencies, a significant loss of customers, and other factors that directly and indirectly effect the results of operations, including the sales and profitability of Berkadia, and consequently may adversely affect our results of operations or financial condition.

Berkadia obtains funds generated by commercial paper sales of an affiliate of Berkadia. All of the proceeds from the commercial paper sales are used by 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 a Berkshire Hathaway corporate guaranty, and we have agreed to reimburse Berkshire Hathaway for one-half of any losses incurred thereunder. If Berkadia suffers significant losses and is unable to repay its commercial paper borrowings, we would suffer losses to the extent of our reimbursement obligation to Berkshire Hathaway. As of November 30, 2021, the aggregate amount of commercial paper outstanding was $1.47 billion.

The Dodd-Frank Wall Street Reform and investments. Consumer Protection Act (the “Dodd-Frank Act”) and the rules and regulations adopted by the CFTC and the SEC introduced a comprehensive regulatory regime for swaps and SBS and parties that deal in such derivatives. One of our subsidiaries is registered as a swap dealer with the CFTC and is a member of the NFA, is registered as a security-based swap dealer with the SEC and is registered with the SEC as an OTC Derivatives Dealer. We have incurred significant compliance and operational costs as a result of the swaps and SBS rules adopted by the CFTC and SEC pursuant to the Dodd-Frank Act, and we expect that the complex regulatory framework will continue to require significant monitoring and compliance expenditures. Negative effects could result from an expansive extraterritorial application of the Dodd-Frank Act and/or insufficient international coordination with respect to adoption of rules for derivatives and other financial reforms in other jurisdictions.

Significant new legislation and regulation affecting the financial services industry is regularly proposed and sometimes adopted. These legislative and regulatory initiatives affect not only us, but also our competitors and certain of our clients. These changes could have an effect on our revenue and profitability, limit our ability to pursue certain business opportunities, impact the value of assets that we hold, require us to change certain business practices, impose additional costs on us and otherwise adversely affect our business. Accordingly, we cannot provide assurance that legislation and regulation will not eventually have an adverse effect on our business, results of operations, cash flows and financial condition. In the U.S., such initiatives frequently arise in the aftermath of elections that change the party of the president or the majority party in the House and/or Senate.

The EU GDPR and UK GDPR also includesinclude restrictions on the transferstransfer of personal data from the EEA to jurisdictions that are not recognized as having "adequatean adequate level of protection with regards to data protection laws".laws. Obligations under the EU GDPR, the UK GDPR and implementing EU Member State legislation continue to evolve through legislation and regulatory guidance, for example imposing further restrictions on use of the standard contractual clauses ("SCCs"(“SCCs”) to transfer personal data to third countries that are not recognized as having an adequate level of data protection by requiring companiesorganizations to carry out a transfer privacy impact assessment.

The EU GDPR imposes significant fines for serious non-compliance of up to the higher of 4% of an organization'sorganization’s annual worldwide turnover or €20 million (or approximately £17.5 million under the U.K.UK GDPR). The EU GDPR identifiesand UK GDPR identify a list of points for the relevant data supervisory authority to consider when determining the level of fines to impose (including the nature, gravity and duration of the infringement). Data subjects also have a right to receive compensation as a result of infringement of the EU GDPR and/or UK GDPR for financial or nonfinancialnon-financial losses.

Other privacy laws at both federal and state levels are in effect in the U.S. and other regions, many of which involve heightened compliance obligations similar to those under EU GDPR and UK GDPR. The privacy and cybersecurity legislative and regulatory landscape is evolving rapidly, and numerous proposals regarding privacy and cybersecurity are pending before U.S. and non-U.S. legislative and regulatory bodies. The adopted form of such developing legislation and regulation will determine the level of any resources which we will need to invest to ensure compliance. In the event of non-compliance with privacy laws and regulations, we could

We are subject to extensive laws, rules and regulations in the countries in which we operate. Firms that engage in providing financial services must comply with the laws, rules and regulations imposed by national and state governments and regulatory and self-regulatory bodies with jurisdiction over such activities. Such laws, rules and regulations cover many aspects of providing financial services.

RegulatorsOur regulators supervise certain of Jefferies Group'sour business activities to monitor compliance with applicable laws, rules and regulations. In addition, if there are instances in which our regulators question our compliance with laws, rules, or regulations, they may investigate the

facts and circumstances to determine whether we have complied. At any moment in time, we may be subject to one or more such investigations or similar reviews. At this time, all such investigations and similar reviews are insignificant in scope and immaterial to us. However, there can be no assurance that, in the future, the operations of our businesses will not violate such laws, rules, or regulations, or that such investigations and similar reviews will not result in significant or material adverse regulatory requirements, regulatory enforcement actions, fines or other adverse impact to the operation of our business.

Additionally, violations of laws, rules and regulations could subject us to one or more of the following events: civil and criminal liability; sanctions, which could include the revocation of our subsidiaries'subsidiaries’ registrations as investment advisors or broker-dealers; the revocation of the licenses of our financial advisors; censures; fines; or a temporary suspension or permanent bar from conducting business. The occurrence of any of these events could have a material adverse effect on our business, financial condition and prospects.

Certain of our subsidiaries are subject to regulatory financial capital holding requirements that could impact various capital allocation decisions or limit the operations of our broker-dealers. In particular, compliance with the financial capital holding requirementsrequirement may restrict our broker-dealers'broker-dealers’ ability to engage in capital-intensive activities such as underwriting and trading, and may also limit their ability to make loans, advances, dividends and other payments and may restrict our swap dealers'dealers’ ability to execute certain derivative transactions.

Additional legislation, changes in rules, changes in the interpretation or enforcement of existing laws and rules, conflicts and inconsistencies among rules and regulations, or the entering into businesses that subject us to new rules and regulations may directly affect our business, results of operations and financial condition. We continue to monitor the impact of new U.S. and international regulation on our businesses.

Many aspects of our businessesbusiness involve substantial risks of liability, and in the normal course of business, we have been named as a defendant or codefendant in lawsuits involving primarily claims for damages. The risks associated with potential legal liabilities often may be difficult to assess or quantify and their existence and magnitude often remain unknown for substantial periods of time. The expansion of our businesses,business, including increases in the number and size of investment banking transactions and our expansion into new areas impose greater risks of liability. Substantial legal liability could have a material adverse financial effect or cause us significant reputational harm, which in turn could seriously harm our business and our prospects.

We are subject to tax in the U.S. and numerous international jurisdictions. Changes to income tax laws and regulations in any of the jurisdictions in which we operate, or in the interpretation of such laws, or the introduction of new taxes, could significantly increase our effective tax rate and ultimately reduce our cash flow from operating activities and otherwise have an adverse effect on our financial condition or results of operations.

We record reserves for unrecognized tax benefits based on our assessment of the probability of successfully sustaining tax filing positions. Management exercises significant judgment when assessing the probability of successfully sustaining tax filing positions, and in determining whether a contingent tax liability should be recorded and, if so, estimating the amount. If our tax filing positions are successfully challenged, payments could be required that are in excess of reserved amounts or we may be required to reduce the carrying amount of our net deferred tax asset, either of which result could be significant to our financial condition or results of operations.

During fiscal 2023, our overall employee count increased by 40.6%, primarily as a result of increases related to obtaining control of Stratos and OpNet as the employees of those subsidiaries are now included in our overall headcount, as well as opportunistic hiring in new regions, slightly offset by a decrease in headcount as a result of the closespin-off of our interests in Vitesse Energy in January 2023.

DuringIn the year ended November 30, 2021, we purchased a total of 8.5 millionnormal course of our common shares for $266.8 million,businesses, we are involved in the execution, settlement and financing of various customer and principal securities and derivative transactions. These activities are transacted on a cash, margin or an average pricedelivery-versus-payment basis and are subject to the risk of $31.25 per share. At November 30, 2021,counterparty or customer nonperformance. Even when transactions are collateralized by the underlying security or other securities, we had approximately $162.5 million available for future repurchases. In January 2022,still face the Boardrisks associated with changes in the market value of Directors increased the share repurchase authorization back up to $250.0 million.

We seek to control the risk associated with these transactions by establishing and monitoring credit limits and by monitoring collateral and transaction levels daily. We may require counterparties to deposit additional collateral or return collateral pledged. In certain circumstances, we repurchasedmay, under industry regulations, purchase the underlying securities in the market and seek reimbursement for any losses from the counterparty. However, there can be no assurances that our risk controls will be successful.

Market risk generally represents the risk that values of assets and liabilities or revenues will be adversely affected by changes in market conditions. Market risk is inherent in the financial instruments associated with our operations and activities, including trading account assets and liabilities, loans, securities, short-term borrowings, corporate debt, and derivatives. Market conditions that change from time to time, thereby exposing us to market risk, include fluctuations in interest rates, equity prices, relative exchange rates, and price deterioration or changes in value due to changes in market perception or actual credit quality of an aggregateissuer.

In addition, disruptions in the liquidity or transparency of 102,805 sharesthe financial markets may result in our inability to sell, syndicate, or realize the value of security positions, thereby leading to increased concentrations. The inability to reduce our positions in specific securities may not only increase the market and credit risks associated with such positions, but also increase capital requirements, which could have an adverse effect on our business, results of operations, financial condition, and liquidity.

The cost and availability of financing generally are impacted by (among other things) our credit ratings. If any of our credit ratings were downgraded, or if rating agencies indicate that a downgrade may occur, our business, financial position and results of operations could be adversely affected and perceptions of our financial strength could be damaged, which could adversely affect our client relationships. Additionally, we intend to access the capital markets and issue debt securities from time to time, and a decrease in our credit ratings or outlook could adversely affect our liquidity and competitive position, increase our borrowing costs, decrease demand for our debt securities and increase the expense and difficulty of financing our operations. In addition, in connection with certain over-the-counter derivative contract arrangements and certain other trading arrangements, we may be required to provide additional collateral to counterparties, exchanges and clearing organizations in the event of a credit rating downgrade. Such a downgrade could also negatively impact the prices of our share compensation plans which allow participants to surrender shares to satisfy certain tax liabilities arisingdebt securities. There can be no assurance that our credit ratings will not be downgraded.

In addition, uncertainty relating to IBORs could result in increased capital requirements for us given potential low transaction volumes, a lack of liquidity or limited observability for exposures linked to IBORs or any emerging successor rates and operational incidents associated with changes in and the discontinuance of IBORs.

Within the past year, concerns have arisen with respect to the financial condition of a number of banking organizations in the United States, in particular those with exposure to certain types of depositors and large portfolios of investment securities. On March 10, 2023, Silicon Valley Bank (“SVB”) was furnishedclosed by S&P Global Market Intelligence. The graph assumesthe California Department of Financial Protection and Innovation. On March 12, 2023, Signature Bank was closed by the New York State Department of Financial Services. On May 1, 2023, First Republic was closed by the California Department of Financial Protection and Innovation. In each case, the Federal Deposit Insurance Corporation (the “FDIC”) was appointed as receiver. While we do not have any exposure to SVB, Signature Bank, or First Republic, we do maintain our cash at financial institutions, often in balances that $100 was investedexceed the current FDIC insurance limits. If other banks and financial institutions enter receivership or become insolvent in the future due to financial conditions affecting the banking system and financial markets, our ability to access our cash, cash equivalents and investments, including transferring funds, making payments or receiving funds, may be threatened and could have a material adverse effect on December 31, 2016our business and financial condition. In addition, the operating environment and public trading prices of financial services sector securities can be highly correlated, in eachparticular in times of stress, which may adversely affect the trading price of our common stock and potentially our results of operations.

Our investment banking revenue, in the S&P 500 Indexform of advisory services and underwriting, is directly related to general economic conditions and corresponding financial market activity. When the outlook for such economic conditions is uncertain or negative, financial market activity generally tends to decrease, which reduces our investment banking revenues. Reduced expectations of U.S. economic growth or a decline in the global economic outlook could cause financial market activity to decrease and negatively affect our investment banking revenues.

In addition, global economic conditions and global financial markets remain vulnerable to the potential risks posed by certain events, which could include, among other things, level and volatility of interest rates, availability and market conditions of financing, economic growth or its sustainability, unforeseen changes to gross domestic product, inflation, energy prices, fluctuations or other changes in both debt and equity capital markets and currencies, political and financial uncertainty in the United States and the European Union, ongoing concern about Asia’s economies, global supply disruptions, complications involving terrorism and armed conflicts around the world (including the conflict between Russia and Ukraine, and Hamas and Israel, or other challenges to global trade or travel, such as those that all dividends were reinvested.have occurred due to the COVID-19 pandemic. More generally, because our business is closely correlated to the general economic outlook, a significant deterioration in that outlook or realization of certain events would likely have an immediate and significant negative impact on our business and overall results of operations.

Maintaining our reputation is critical to our attracting and maintaining customers, investors and employees. If we fail to deal with, or appear to fail to deal with, various issues that may give rise to reputational risk, we could significantly harm our business prospects. These issues include, but are not limited to, any of the risks discussed in this Item 1A, appropriately dealing with potential conflicts of interest, legal and regulatory requirements, ethical issues, money-laundering, cybersecurity and privacy, record keeping, sales and trading practices, failure to sell securities we have underwritten at the anticipated price levels, and the proper identification of the legal, reputational, credit, liquidity and market risks inherent in our products. A failure to deliver appropriate standards of service and quality, or a failure or perceived failure to treat customers and clients fairly, can result in customer dissatisfaction, litigation and heightened regulatory scrutiny, all of which can lead to lost revenue, higher operating costs and harm to our reputation. Further, negative publicity regarding us, whether or not true, may also result in harm to our prospects. Our operations in the past have been summarized fromimpacted as some clients either ceased doing business or temporarily slowed down the level of business they do, thereby decreasing our consolidatedrevenue. There is no assurance that we will be able to successfully reverse the negative impact of allegations and rumors in the future and our potential failure to do so could have a material adverse effect on our business, financial statements. They should be read in conjunction withcondition and liquidity.

We seek to monitor and Item 7, Management'scontrol our risk exposure. Our risk management processes and procedures are designed to limit our exposure to acceptable levels as we conduct our business. We apply a comprehensive framework of limits on a variety of key metrics to constrain the risk profile of our business activities. These limits reflect our risk tolerances for business activity. Our framework includes inventory position and exposure limits on a gross and net basis, scenario analysis and stress tests, Value-at-Risk, sensitivities, exposure concentrations, aged inventory, amount of Level 3 assets, counterparty exposure, leverage, cash capital and performance analysis. See Management’s Discussion and Analysis of Financial Condition and Results of Operations - Risk Management within Part II. Item 7. of this report.

Statements includedTurnover in this report may contain forward-looking statements. Such statements may relate, butthe financial services industry is high. The cost of retaining skilled professionals in the financial services industry has escalated considerably. Financial industry employers are not limited,increasingly offering guaranteed contracts, upfront payments, and increased compensation. These can be important factors in a current employee’s decision to projections of revenues, income or loss, development expenditures, plans for growth and future operations, competition and regulation,leave us as well as assumptionsin a prospective employee’s decision to join us. As competition for skilled professionals in the industry remains intense, we may have to devote significant resources to attracting and retaining qualified personnel.

Further, in light of the high volume of transactions we process, the large number of our clients, partners and counterparties, and the increasing sophistication of malicious actors that may employ increasingly sophisticated methods such as new artificial intelligence tools, a cyber attack, cybersecurity incident, or other information security breach could occur and persist for an extended period of time without detection. We expect that any investigation of a cyber attack, cybersecurity incident, or other information security breach would take substantial amounts of time and resources, and that there may be extensive delays before we obtain full and reliable information. During such time we would not necessarily know the extent of the harm caused by the cyber attack, cybersecurity incident, or other information security breach or how best to remediate it, and certain errors or actions could be repeated or compounded before they are discovered and remediated. All of these factors could further increase the costs and consequences of such a cyber attack or cybersecurity incident. In providing services to clients, we manage, utilize and store sensitive or confidential client or employee data, including personal data. As a result, we are subject to numerous laws and regulations designed to protect this information, such as U.S. and non-U.S. federal and state laws governing privacy and cybersecurity. If any person, including any of our associates, negligently disregards or intentionally breaches our established controls with respect to client or employee data, or otherwise mismanages or misappropriates such data, we could be subject to significant monetary damages, regulatory enforcement actions, fines and/or criminal prosecution. In addition, unauthorized disclosure of sensitive or confidential client or employee data, whether through system compromise or failure, employee negligence, fraud or misappropriation, could damage our reputation and cause us to lose clients and related revenue.

Berkadia obtains funds generated by commercial paper sales of an affiliate of Berkadia. All of the proceeds from the commercial paper sales are used by 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 a Berkshire Hathaway corporate guaranty, and we have agreed to reimburse Berkshire Hathaway for one-half of any losses incurred thereunder.

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and the rules and regulations adopted by the CFTC and the SEC introduced a comprehensive regulatory regime for swaps and SBS and parties that deal in such derivatives. One of our subsidiaries is registered as follows (in thousands):a swap dealer with the CFTC and is a member of the NFA, is registered as a security-based swap dealer with the SEC and is registered with the SEC as an OTC Derivatives Dealer. We have incurred significant compliance and operational costs as a result of the swaps and SBS rules adopted by the CFTC and SEC pursuant to the Dodd-Frank Act, and we expect that the complex regulatory framework will continue to require significant monitoring and compliance expenditures. Negative effects could result from an expansive extraterritorial application of the Dodd-Frank Act and/or insufficient international coordination with respect to adoption of rules for derivatives and other financial reforms in other jurisdictions.

Additionally, violations of laws, rules and regulations could subject us to one or more of the following events: civil and criminal liability; sanctions, which could include the revocation of our subsidiaries’ registrations as investment advisors or broker-dealers; the revocation of the licenses of our financial advisors; censures; fines; or a temporary suspension or permanent bar from conducting business. The occurrence of any of these events could have a material adverse effect on our business, financial condition and prospects.

Approximately 51.3%, 37.9% and 10.9% of our workforce distributed across the Americas, Europe and the Middle East and Asia-Pacific, respectively. Included within our global headcount, in addition to our broker-dealer subsidiaries through which we conduct our Investment Banking advisory and underwriting businesses and Fixed Income and Equities capital markets businesses, are 2,296 employees of our Stratos, OpNet, HomeFed, Foursight Capital LLC and M Science subsidiaries.

During fiscal 2023, our overall employee count increased by 40.6%, primarily as follows (in thousands):a result of increases related to obtaining control of Stratos and OpNet as the employees of those subsidiaries are now included in our overall headcount, as well as opportunistic hiring in new regions, slightly offset by a decrease in headcount as a result of the spin-off of our interests in Vitesse Energy in January 2023. In 2023, we expanded our global footprint by hiring professionals into new locations, including Dubai, São Paolo, Tel Aviv, and Toronto.

In order to compete effectively and continue to provide best-in-class service to our clients, we must attract, retain, and motivate qualified professionals. Our core workforce is predominately composed of employees in roles such as investment bankers, sales, trading, research professionals and other revenue producing or support personnel. During 2023, our headcount increased by 2,183 related primarily to hiring of professionals globally as well as the addition of professionals as a result of our acquisitions of Stratos and OpNet. While our investment is largely in Investment Banking, there has also been meaningful additional investments in Equities, Fixed Income, Research, Support and Alternative Asset Management. Within our Investment Banking and Capital Markets reportable segment, comprises manyour voluntary turnover rate was 7.9%, which makes our overall retention rate very high in our view.

Our Board has an ESG, Diversity, Equity and Inclusion (“ESG/DEI”) Committee, which, among them.other things, oversees the sustainability matters arising from our business and includes oversight over diversity and inclusion. The ESG/DEI Committee demonstrates our and the Board’s ongoing commitment of driving and fostering diversity in the workforce and in the communities in which we operate.

In the normal course of our businesses, we are involved in the execution, settlement and financing of various customer and principal securities and derivative transactions. These activities are transacted on a cash, margin or delivery-versus-payment basis and are subject to the risk of counterparty or customer nonperformance. Even when transactions are collateralized by the underlying security or other securities, we still face the risks associated with changes in the market value of the collateral through settlement date or during the time when margin is extended and collateral has not been secured or the counterparty defaults before collateral or margin can be adjusted. We may also incur credit risk in our derivative transactions to the extent such transactions result in uncollateralized credit exposure to our counterparties.

Market risk generally represents the risk that values of assets and liabilities or revenues will be adversely affected by changes in market conditions. Market risk is inherent in the financial instruments associated with our operations and activities, including trading account assets and liabilities, loans, securities, short-term borrowings, corporate debt, and derivatives. Market conditions that change from time to time, thereby exposing us to market risk, include fluctuations in interest rates, equity prices, relative exchange rates, and price deterioration or changes in value due to changes in market perception or actual credit quality of an issuer.

In addition, disruptions in the sales,liquidity or transparency of the financial markets may result in our inability to sell, syndicate, or realize the value of security positions, thereby leading to increased concentrations. The inability to reduce our positions in specific securities may not only increase the market and credit risks associated with such positions, but also increase capital requirements, which could have an adverse effect on our business, results of operations, financial condition, and liquidity.

A considerable portion of our revenues is derived from trading originationin which we act as principal. We may incur trading losses relating to the purchase, sale or short sale of fixed income, high yield, international, convertible, and advisory effortequity securities, loans, derivative contracts and commodities for variousour own account. In any period, we may experience losses on our inventory positions as a result of the level and volatility of equity, fixed income commodities,and commodity prices (including oil prices), lack of trading volume and illiquidity. From time to time, we may engage in a large block trade in a single security or maintain large position concentrations in a single security, securities of a single issuer, securities of issuers engaged in a specific industry, or securities from issuers located in a particular country or region. In general, because our inventory is marked to market on a daily basis, any adverse price movement in these securities could result in a reduction of our revenues and profits. In addition, we may engage in hedging transactions that if not successful, could result in losses. Increased market volatility may also impact our revenues as transaction activity in our investment banking and capital markets sales and trading businesses can be negatively impacted in a volatile market environment.
