Illiquidity, Solvency & Insolvency : A Link to Bankruptcy Procedures

January 14, 2025 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2025) delves into the illiquidity, solvency and insolvency, key concepts in that connect financial distress and bankruptcy procedures.

Illiquidity

Illiquidity refers to the inability of a company or individual to convert assets into cash quickly enough to meet short-term financial obligations as they come due. This condition arises from a mismatch in the timing of cash inflows and outflows rather than a fundamental deficiency in overall financial health. For instance, a firm might hold substantial non-liquid assets (e.g., accounts receivable or inventory) that are valuable but not immediately accessible for use in settling debts. Illiquidity is generally viewed as a short-term liquidity risk and is often addressed through measures such as enhanced cash flow management, securing bridge financing, or leveraging credit facilities.

Solvency and Insolvency

Solvency refers to the financial health of an entity, where its assets exceed its liabilities, and it can meet its financial obligations as they fall due (although not in the short term as explained below). A solvent entity demonstrates financial stability and sustainability, which are key factors for stakeholders, such as debt holders (for liquidity reasons at the time debt deadlines) and especially equity holders (for performance reason).

Conversely, insolvency is a financial condition in which an entity’s liabilities exceed its assets, or it is unable to meet its debt obligations as they become due. It represents a state of long-term financial distress, indicating that the entity lacks sufficient resources to satisfy its obligations, even with adequate time to manage cash flows.

Insolvency can manifest in two primary forms:

Balance Sheet Insolvency: Occurs when the total liabilities of a company exceed its total assets. This is typically assessed using the entity’s balance sheet, where negative equity (assets minus liabilities) signals insolvency.

Cash Flow Insolvency: Occurs when an entity cannot pay its debts as they fall due, despite potentially having assets that exceed liabilities. This happens when illiquid assets cannot be quickly converted to cash to meet immediate obligations.

Insolvency is distinct from illiquidity in that it reflects a fundamental imbalance in financial health rather than a short-term cash flow issue. Prolonged insolvency often leads to bankruptcy filings, where legal proceedings determine whether the business should be restructured or liquidated.

Valuation Perspective: Solvency and Insolvency via Net Present Value (NPV)

Formula for Net Present Value (NPV)

The Net Present Value (NPV) is calculated using the following formula:

Figure 1. Net Present Value (NPV) Formula

In this context, cash flows represent the value generated by the firm’s assets, while the discount rate reflects the required return on debt and equity financing. A positive NPV signifies that the firm or project creates value above its cost of capital, while a negative NPV indicates value destruction and financial risk.

From a valuation standpoint, Net Present Value (NPV) is a crucial metric that aligns with the solvency status of an entity. NPV evaluates the difference between the present value of cash inflows and the present value of cash outflows over a given period. It serves as an indicator of the financial viability of a firm or project.

Solvent Firms: NPV > 0

A positive NPV indicates that the firm or project is generating value in excess of the required rate of return.

Such firms are financially sustainable, with the potential to attract investments, repay debts, and grow operations.

Example: A profitable company with strong operational cash flows and prudent capital investments will exhibit a positive NPV.

Insolvent Firms: NPV < 0

A negative NPV signals that the firm or project is destroying value, as cash outflows exceed the discounted cash inflows.

These firms struggle to generate sufficient returns, often resulting in financial distress and eventual insolvency.

Example: A company burdened by declining revenues, rising costs, and high-interest obligations may show a negative NPV.

Bankruptcy Basics

Bankruptcy is a legal framework that helps individuals and businesses unable to meet their financial obligations in the short term. When a company files for bankruptcy, it either seeks to reorganize its debts and operations or liquidate its assets to repay creditors, depending on the type of bankruptcy pursued (Chapter 7 for liquidation or Chapter 11 for reorganization procedures in US bankruptcy law). Reorganisation can offer a pathway to stability, enabling companies to mitigate debt burdens, restructure, and potentially preserve jobs. In this post I explain the link between the two academic concepts of illiquidity and insolvency and the two paths of bankruptcy of liquidation and reorganization.

Liquidation (Chapter 7 Bankruptcy)

Liquidation, often governed by specific bankruptcy codes such as Chapter 7 in the U.S., involves the complete dissolution of a financially distressed entity. Under this process, the firm’s assets are sold off to repay creditors in a legally prioritized manner. Liquidation is typically the final recourse for insolvent entities that lack the ability to restructure or continue operations. It marks the end of the entity’s existence, with any remaining proceeds distributed to stakeholders after settling liabilities.

Reorganization (Chapter 11 Bankruptcy)

Reorganization, outlined under codes such as Chapter 11 in the U.S., is designed for insolvent entities seeking to restructure their debts and operations while continuing business activities. This process allows the firm to negotiate with creditors to modify repayment terms, reduce debt burdens, or inject fresh capital. Reorganization aims to restore financial stability, preserving the firm’s value and jobs while maximizing recoveries for creditors. It is a more sustainable alternative to liquidation for viable but financially distressed firms.

Link between Illiquidity, Solvency, and Bankruptcy Outcomes

The determination of whether an illiquid firm should undergo liquidation or reorganization is heavily influenced by its solvency or insolvency status. These financial characteristics provide a structured framework to allocate resources and protect stakeholder interests, ensuring an efficient resolution process that minimizes economic disruption.

Illiquidity and Insolvent Companies: Liquidation

A firm that is both illiquid (unable to meet its short-term obligations) and insolvent (its liabilities exceed its assets) is in a critical financial position. These firms lack the operational capacity to generate sufficient cash flows and the balance sheet strength to cover their obligations. By selling off assets, the firm can repay creditors in an orderly and legally prioritized manner, thereby closing its operations permanently. Liquidation minimizes further losses and provides a clear exit for stakeholders, ensuring that remaining value is distributed equitably.

From a financial perspective:

Asset Realization: Liquidation involves selling the firm’s assets, converting illiquid assets (e.g., inventory, real estate) into cash to settle liabilities.

Creditor Recovery: Creditors are repaid in a hierarchical order—secured creditors (e.g., bondholders) take precedence, followed by unsecured creditors and equity holders.

Economic Efficiency: Liquidation prevents further erosion of value by discontinuing loss-making operations. The proceeds can be redeployed to more productive uses within the economy.

Example: In high-leverage industries such as retail, where asset values may plummet during financial distress, liquidation can be a pragmatic approach to salvaging any remaining value for stakeholders.

Illiquidity and Solvent Companies: Reorganization

Firms that are illiquid (unable to meet its short-term obligations) but remain solvent (its assets exceed its liabilities) present a different scenario. These companies face temporary liquidity constraints but possess the potential for recovery, given their fundamentally sound financial or economic position. By restructuring debts and operations under judicial supervision, reorganization allows the firm to stabilize its finances, regain liquidity, and continue its business activities. This approach helps preserve jobs, maintain operational continuity, and often results in better recovery for creditors compared to liquidation.

Key financial points include:

Debt Restructuring: The firm negotiates with creditors to extend repayment timelines, reduce interest rates, or convert debt into equity, improving short-term liquidity.

Operational Optimization: Reorganization often involves strategic cost-cutting, asset divestitures, or operational restructuring to enhance cash flow generation.

Stakeholder Value Preservation: By avoiding liquidation, reorganization preserves enterprise value, ensuring better recovery for creditors and protecting equity holders’ stakes.

Long-term Viability: Reorganized firms can often leverage their existing assets and market position to regain profitability, benefiting employees, suppliers, and customers.

Example: Airlines facing temporary cash flow issues during economic downturns often turn to reorganization. By negotiating with lessors, restructuring debt, and optimizing operations, they can avoid liquidation and return to profitability.

An Efficient Bankruptcy Procedure

An efficient bankruptcy procedure should distinguish between these two cases (solvent and insolvent firms), leading illiquid and insolvent firms into liquidation and illiquid but solvent firms into reorganization. This tailored approach ensures that:

Insolvent firms with no viable future are dissolved efficiently, maximizing recoveries for creditors.

Solvent but illiquid firms are given a second chance to reorganize and emerge stronger, preserving value for all stakeholders.

Figure 4. Efficient Bankruptcy Procedure

Such a system not only protects creditors and investors but also fosters economic stability by maintaining productive assets and employment where possible, while swiftly resolving entities that no longer contribute to the economy.

This approach not only maximizes financial efficiency but also aligns with broader economic objectives:

Maximizing Creditor Recovery: Insolvent firms should be liquidated to repay creditors as much as possible, avoiding the dilution of recovery through prolonged unviable operations.

Optimizing Economic Resources: Solvent but illiquid firms should undergo reorganization, preserving their workforce, intellectual property, and market position, which might otherwise be lost in liquidation.

Minimizing Systemic Risk: A clear distinction between liquidation and reorganization reduces uncertainty in financial markets, particularly for industries prone to cyclical liquidity crises.

Chapter 11 Bankruptcies: A Strategic Insight on Reorganisations

January 14, 2025 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2025) explores the complexities of Chapter 11 bankruptcy laws in the United States, examining how this legal process impacts businesses facing financial distress. With insights into reorganisation (Chapter 11), this post provides a detailed overview of this chapter’s purpose, process, and strategic implications. By examining the purpose, procedures, and strategic implications of Chapter 11, this post sheds light on how firms navigate debt management and financial recovery.

Bankruptcy Basics

Bankruptcy is often perceived as a last resort for struggling businesses, a measure taken when all other avenues for debt resolution have been exhausted. However, for businesses of all sizes, understanding bankruptcy is crucial—not only as a potential safeguard but as a strategic consideration in financial planning and risk management. This knowledge becomes increasingly important in today’s volatile global economy, where the financial resilience of a business can determine its survival and growth.

Bankruptcy is a legal framework that helps individuals and businesses unable to meet their financial obligations. When a company files for bankruptcy, it either seeks to reorganize its debts and operations or liquidate its assets to repay creditors, depending on the type of bankruptcy pursued (Chapter 7 or Chapter 11 procedures in US bankruptcy law). Bankruptcy can offer a pathway to stability, enabling companies to mitigate debt burdens, restructure, and potentially preserve jobs.

Legal Definition and Purpose of Chapter 11 Bankruptcy

Chapter 11 bankruptcy, commonly known as “reorganisation bankruptcy,” is a legal mechanism under Title 11 of the United States Code that allows financially distressed businesses to restructure their debts and operations while continuing to function. Unlike Chapter 7, which focuses on liquidation, Chapter 11 aims to preserve the business as a going concern, enabling it to regain profitability while protecting creditors’ interests.

Legal Definition: Chapter 11 provides a structured process through which a debtor proposes a reorganisation plan to address its financial obligations. This plan may involve renegotiating debt terms, selling non-core assets, downsizing operations, or finding new investment capital. The reorganisation plan must be approved by the bankruptcy court and often requires agreement from creditors, ensuring fairness and feasibility.

Purpose: The primary objective of Chapter 11 is to balance two critical goals:

Business Rehabilitation: By allowing the debtor to restructure debts rather than liquidate, Chapter 11 ensures that valuable business operations, jobs, and economic contributions are preserved. This is particularly vital for companies with potential long-term viability but temporary financial challenges.

Creditor Protection: The process safeguards creditor interests by ensuring orderly repayment according to a court-approved priority structure. Secured creditors typically recover from collateral-backed assets, while unsecured creditors negotiate for partial repayment through the reorganisation plan.

Chapter 11 is especially beneficial for medium-to-large corporations that need significant operational restructuring or whose debt structure requires complex renegotiation. The process is overseen by a debtor-in-possession (DIP), meaning the company’s existing management continues to operate the business under court supervision while implementing the reorganization plan. The court’s role ensures transparency, equity, and adherence to legal requirements, protecting all stakeholders throughout the process.

Chapter 11 enables businesses to restructure their debt obligations and operations without halting business activities. This process can offer significant advantages, especially for companies with strong core operations but temporary cash flow or liquidity issues. In 2023, approximately 25% of business bankruptcies filed in the U.S. were Chapter 11 cases, showing its popularity among companies aiming to reorganize rather than liquidate.

Key Objectives of Chapter 11

Debt Relief: Restructure and reduce debt obligations to improve cash flow.

Operational Reorganization: Adjust operations to align better with financial health, often through cost-cutting, downsizing, or strategic pivots.

Business Continuity: Unlike Chapter 7, Chapter 11 allows businesses to continue operations, retain jobs, and maintain relationships with customers and suppliers.

Eligibility and Who Can File:

Chapter 11 is primarily available to corporations, partnerships, and sole proprietorships. However, it is most commonly used by medium to large businesses that have a chance to recover.

For individuals, Chapter 11 is an option if they exceed the debt limits set for Chapter 13, though it is rare in personal bankruptcies due to its complexity and cost.

Common Causes of Business Bankruptcy

Chapter 11 bankruptcy is often a lifeline for businesses facing financial distress but with the potential for recovery through reorganizsation. Unlike Chapter 7, which involves liquidation, Chapter 11 allows companies to address their challenges by restructuring debts and operations. Several factors commonly drive businesses into Chapter 11 bankruptcy, reflecting a combination of internal inefficiencies and external pressures.

One major cause is an excessive debt burden, where businesses accumulate unsustainable liabilities relative to their income. This can become unmanageable during revenue declines or rising interest rates. Similarly, declining revenues caused by market shifts, competition, or external shocks often leave businesses unable to meet financial obligations. Economic downturns and external crises like recessions or global pandemics further exacerbate financial distress. In addition to economic pressures, overexpansion is another common issue. Businesses that grow too quickly without sufficient financial planning can overextend resources. Operational challenges such as inefficiencies or failure to innovate are also critical factors. Companies that fail to adapt to changing markets risk becoming obsolete. Additionally, supply chain disruptions, such as delays or rising costs, can disrupt operations, especially for businesses reliant on just-in-time systems. These issues can significantly strain cash flow and increase financial pressure.

Legal challenges often play a role in driving Chapter 11 filings as well. Large settlements, lawsuits, or regulatory fines can create sudden financial burdens that businesses struggle to manage. Cash flow management is another critical issue. Poor working capital planning can leave businesses unable to cover short-term obligations. Retailers with seasonal sales spikes often struggle during off-peak periods, leading to financial distress. Finally, industry disruption caused by technological advancements or shifting consumer preferences can force businesses into bankruptcy.

Businesses typically face bankruptcy due to a mix of internal and external factors. Key factors include:

Excessive Debt Burden
Cause: High levels of debt relative to income can leave businesses unable to service loans, especially during periods of declining revenue or rising interest rates.

Example: Hertz Corporation filed for Chapter 11 in 2020 with over $5 billion in debt. The pandemic-driven collapse in travel demand exacerbated its inability to meet financial obligations.

Declining Revenues
Cause: Sustained revenue declines due to market changes, competition, or external shocks can reduce a company’s ability to cover operating expenses and debt repayments.

Example: American Airlines filed for Chapter 11 in 2011 due to declining revenues from rising fuel costs and competition, using the process to restructure its debt and cut costs.

Economic Downturns and External Crises
Cause: Recessions, global crises, or industry-specific downturns can severely impact revenues and cash flow, driving businesses into insolvency.

Example: The COVID-19 pandemic led to a wave of Chapter 11 filings in 2020, including companies like JC Penney and Neiman Marcus, which faced plummeting consumer demand during lockdowns.

Overexpansion
Cause: Rapid growth without adequate financial controls or market analysis can stretch resources and leave businesses vulnerable to cash flow problems.

Example: Sbarro, a pizza chain, filed for Chapter 11 in 2011 and again in 2014 after overexpanding into underperforming locations, resulting in significant operational inefficiencies.

Operational Inefficiencies
Cause: Ineffective cost management, outdated business models, or failure to innovate can erode profitability, making it difficult to sustain operations.

Example: Kodak filed for Chapter 11 in 2012 due to its inability to adapt to the digital revolution, which rendered its traditional film business obsolete.

Supply Chain Disruptions
Cause: Delays, shortages, or rising costs in supply chains can disrupt production and increase operating expenses, especially for companies dependent on just-in-time systems.

Example: In 2022, many small-to-medium-sized manufacturers in industries like electronics and automotive struggled with supply chain issues, driving some to seek Chapter 11 protection.

Legal Liabilities
Cause: Large settlements, regulatory fines, or lawsuits can create significant financial burdens that businesses cannot manage without restructuring.

Example: Purdue Pharma filed for Chapter 11 in 2019 as part of a settlement to resolve thousands of lawsuits related to the opioid crisis.

Poor Cash Flow Management
Cause: Failure to manage working capital effectively can lead to cash shortages, making it difficult to pay creditors or fund day-to-day operations.

Example: A mid-sized retailer with strong seasonal sales but poor cash flow planning might file for Chapter 11 to restructure its payment obligations during off-peak periods.

High Fixed Costs
Cause: Businesses with significant fixed costs, such as long-term leases or equipment financing, face challenges when revenues fall, as these costs cannot easily be reduced.

Example: JC Penney faced mounting lease expenses and declining store traffic, ultimately filing for Chapter 11 in 2020 to renegotiate terms and restructure operations.

Industry Disruption
Cause: Technological innovation, shifting consumer preferences, or the entrance of disruptive competitors can weaken traditional business models.

Example: Blockbuster filed for Chapter 11 after streaming services like Netflix and Hulu fundamentally disrupted the home entertainment industry.

Key Steps in a Chapter 11 Filing

Filing the Petition and Automatic Stay
- Filing: The Chapter 11 process begins when the debtor files a petition in bankruptcy court. This petition includes comprehensive details about the company’s financial status, such as assets, liabilities, income, expenses, and financial history.
- Automatic Stay: The moment the petition is filed, an automatic stay takes effect, immediately halting all collection actions by creditors. This stay provides the company with breathing room to reorganize without the threat of foreclosure or asset seizure. The automatic stay is crucial for companies in Chapter 11, as it allows operations to continue while management restructures.
Development and Approval of the Reorganization Plan
- Plan Development: The debtor, acting as a “debtor-in-possession” (DIP), typically retains control over business operations. The company is tasked with drafting a reorganization plan, which outlines how it will repay creditors, restructure operations, and achieve profitability.
- Creditor Negotiations: The company works with creditors to gain their support for the reorganization plan. In most cases, the plan must be approved by at least one class of impaired creditors (those not expected to be fully repaid). This approval can involve debt rescheduling, asset sales, or reductions in debt.
- Court Approval: Once creditors approve the plan, the bankruptcy court must confirm it. The court assesses whether the plan is feasible, fair, and in the best interests of creditors. This phase can be complex and costly, as it often requires multiple hearings and potential modifications to satisfy all parties.
Execution and Emergence from Bankruptcy
- Implementation: After court approval, the company begins implementing the reorganization plan, following all terms outlined to repay creditors over time. Changes may include asset sales, layoffs, new debt issuance, or equity restructuring.
- Emergence from Chapter 11: Once the company fulfils the terms of the reorganization plan, it officially exits Chapter 11. This process can take several months to years, depending on the company’s complexity and debt structure. For instance, American Airlines emerged from Chapter 11 after two years of restructuring, merging with US Airways to enhance market competitiveness.

Benefits of Restructuring vs. Liquidation

Preserving Business Value: Reorganization allows the company to maintain operations, preserving its market presence, assets, and workforce. For example, Hertz used Chapter 11 in 2020 to restructure over $5 billion in debt, allowing it to continue operating and ultimately emerge stronger after the pandemic.

Maximizing Creditor Recoveries: Creditors are often more willing to negotiate in Chapter 11, as reorganization usually yields better recoveries than liquidation. According to research, Chapter 11 cases result in creditor recoveries averaging 20-25% higher than Chapter 7 cases due to continued asset generation.

Opportunity for Operational Efficiency: Companies can use Chapter 11 to optimize operations by renegotiating leases, reducing payroll, and streamlining production. These changes help improve financial health and long-term viability.

Risks and Challenges in the Reorganization Process

Cost and Complexity: Chapter 11 can be extremely costly, especially for larger businesses. Legal fees, administrative expenses, and consulting costs can run into millions. A 2019 study revealed that legal and administrative expenses for large Chapter 11 cases average between $1 million and $10 million. For example, Lehman Brothers’ bankruptcy case, the largest in U.S. history, accrued $2.2 billion in fees over its restructuring period.

Extended Time Frame: Chapter 11 cases can be lengthy, taking months or even years to complete. This time commitment may strain cash flow and delay recovery, particularly if the business is in a highly competitive industry. In Hertz’s case, the Chapter 11 process lasted 17 months, and the company only emerged after securing additional financing and renegotiating debt terms.

Uncertainty in Creditor Approval: Creditors must approve the reorganization plan, which can be challenging if there are conflicting interests among different creditor classes. If major creditor groups reject the plan, the court can enforce a “cramdown,” but this is often a contentious and uncertain process.

Risk of Conversion to Chapter 7: If a reorganization plan fails, or the business cannot achieve sustainable operations, the case may be converted to Chapter 7, leading to liquidation. This outcome results in further losses for stakeholders, as assets are sold off, and the business ceases operations.

Debtor-in-Possession (DIP) Financing: Definition, Purpose, and Relevance in Chapter 11 Filings

Debtor-in-Possession (DIP) financing is a specialized form of funding that allows businesses undergoing Chapter 11 bankruptcy to secure the liquidity needed to continue operations during the reorganization process. The term “debtor-in-possession” refers to the debtor retaining control of its assets and operations while the bankruptcy case is under court supervision. Unlike standard loans, DIP financing is uniquely designed for companies in financial distress and requires court approval to ensure fairness and transparency.

Definition and Features

DIP financing is a post-petition loan that takes precedence over most existing debts, including secured loans, under U.S. bankruptcy law. This super-priority status ensures that DIP lenders are repaid before pre-petition creditors, making the financing attractive even for lenders dealing with financially distressed companies. The terms of DIP financing often include strict covenants, requiring the debtor to adhere to the reorganization plan and meet operational milestones.

Purpose of DIP Financing.

The primary purpose of DIP financing is to provide businesses with the liquidity needed to continue essential operations during the reorganization process. This includes paying employees, suppliers, and other operating expenses. Without this funding, many companies would face operational paralysis, undermining the feasibility of reorganization.

Maintain Operations: Fund day-to-day activities such as payroll, supplier payments, and utility bills to prevent operational shutdown.

Stabilize the Business: Provide working capital to preserve the company’s going-concern value, ensuring it can generate revenue during the restructuring process.

Support Creditor Confidence: By maintaining operations, DIP financing reassures creditors that the debtor is working toward recovery and maximising the value of their claims.

Relevance in Chapter 11 Bankruptcies

DIP financing plays a pivotal role in Chapter 11 filings, bridging the gap between insolvency and reorganization. A business in financial distress often lacks the liquidity to continue operations, which is critical to preserving asset value and employee morale during bankruptcy. Without DIP financing, many companies would be forced to liquidate under Chapter 7, leading to the loss of jobs, assets, and creditor recoveries.

For creditors, DIP financing ensures that the company retains its going-concern value, which typically leads to higher recoveries than a piecemeal liquidation. The court-approved nature of DIP financing also provides a transparent framework for ensuring that new and existing creditors are treated fairly.

Case Study: Hertz Global Holdings – A Successful Chapter 11 Reorganization

Background

Hertz Global Holdings, one of the largest car rental companies in the world, filed for Chapter 11 bankruptcy on May 22, 2020, during the height of the COVID-19 pandemic. Founded in 1918, Hertz operated a fleet of over 700,000 vehicles across 12,000 locations worldwide. Despite its strong market presence, the company faced mounting financial pressures exacerbated by the collapse of global travel during the pandemic.

Causes of Financial Distress

Revenue Collapse: The COVID-19 pandemic caused a dramatic decline in travel demand, with global car rental revenues dropping by nearly 50% in 2020. Hertz’s core business was severely affected, leading to unsustainable losses.

Excessive Debt: Hertz entered the pandemic carrying over $19 billion in total debt, including vehicle leasing obligations. The revenue shortfall made it impossible for the company to service its debt.

Operational Challenges: Hertz struggled with a bloated fleet and high fixed costs. The sudden drop in demand left thousands of vehicles idle, further straining the company’s cash flow.

The Chapter 11 Filing

Hertz filed for Chapter 11 protection to restructure its debts and operations while continuing to operate. The reorganization aimed to address several key issues:

Debt Restructuring: Hertz sought to renegotiate terms with creditors to reduce its debt load and extend repayment periods.

Fleet Optimization: The company planned to sell off a portion of its vehicle inventory to generate cash and align fleet size with demand.

Securing Financing: Hertz needed additional liquidity to sustain operations during the reorganization process.

Key Steps in the Reorganization Process

Debtor-in-Possession (DIP) Financing: Hertz secured $1.65 billion in DIP financing to fund its operations during bankruptcy. This financing provided the necessary cash flow to continue serving customers and paying employees while restructuring.

Asset Sales: Hertz sold off approximately 200,000 vehicles from its fleet, generating liquidity and reducing carrying costs. This move also allowed the company to focus on optimizing its remaining assets.

Debt Negotiations: Hertz renegotiated with creditors to eliminate nearly $5 billion in debt. Creditors received equity and cash payments in exchange, ensuring some recovery while allowing the company to stabilize.

Strategic Investment: In May 2021, Hertz exited bankruptcy after receiving a $5.9 billion equity injection from a group of institutional investors, including Knighthead Capital and Certares Management. This recapitalization provided a strong financial foundation for the company’s post-bankruptcy growth.

Outcome

Hertz emerged from Chapter 11 on June 30, 2021, as a leaner and more competitive company. The reorganization allowed the company to:

Reduce Debt: Hertz significantly reduced its debt obligations, creating a more sustainable financial structure.

Optimize Operations: The sale of excess vehicles and strategic investments in fleet technology enhanced efficiency.

Leverage New Opportunities: Post-reorganization, Hertz announced plans to invest in electric vehicles (EVs), including a major purchase of 100,000 Teslas in 2021, positioning itself as a leader in the EV rental market.

Impact on Stakeholders

Creditors: Creditors recovered a portion of their investments through equity stakes and cash payments, avoiding the complete loss often associated with liquidation.

Employees: The reorganization preserved thousands of jobs, allowing Hertz to retain its workforce while stabilizing operations.

Customers: Hertz continued serving customers without major disruptions, ensuring the brand’s market presence remained intact.

Investors: The post-bankruptcy equity investment attracted new institutional investors, reflecting confidence in Hertz’s growth potential.

Lessons for Students

Importance of DIP Financing: Securing DIP financing is critical for maintaining operations during reorganization. Hertz’s ability to secure $1.65 billion ensured stability during a turbulent period.

Strategic Asset Management: Selling non-core assets, such as excess fleet vehicles, is a practical way to generate liquidity and reduce costs in Chapter 11 cases.

Investor Confidence: Attracting strategic investors during reorganization can provide not only financial resources but also market credibility.

Adaptability and Innovation: Post-bankruptcy, Hertz’s pivot toward electric vehicles demonstrates the importance of aligning business strategies with future market trends.

Chapter 7 Bankruptcies: A Strategic Insight on Liquidations

December 24, 2024December 18, 2024 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2025) delves into the intricacies of bankruptcy laws, focusing on the pivotal role of Chapter 7 in the United States. This legal framework governs the liquidation process, providing a structured approach for businesses facing severe financial distress. By examining the purpose, procedures, and strategic implications of Chapter 7, this post sheds light on how firms navigate debt management and financial recovery.

Bankruptcy Basics

Legal Definition and Purpose of Chapter 7 Bankruptcy

Chapter 7 bankruptcy, often referred to as “liquidation bankruptcy,” is a legal process under the U.S. Bankruptcy Code that allows individuals and businesses to discharge most of their unsecured debts by liquidating non-exempt assets.

The purpose of Chapter 7 – Liquidation is two fold:

To provide a “fresh start” for debtors who are unable to repay their debts by eliminating the legal obligation for most outstanding liabilities.

To maximize recovery for creditors by selling the debtor’s assets and distributing the proceeds according to a court-approved priority system.

Chapter 7 bankruptcy is widely used when a business is unable to operate profitably or lacks the means to restructure effectively. Chapter 7 typically results in the complete closure of a business, with its assets sold off to repay creditors, as opposed to reorganization under Chapter 11. Below is a detailed breakdown of the Chapter 7 process, implications, and a real-world case study to provide further insight.

Eligibility Criteria: To file under Chapter 7, a business or individual must demonstrate insolvency, where liabilities exceed assets. However, certain entities, such as governmental units and banks, are ineligible and must pursue other legal avenues if insolvent.

This type of bankruptcy is typically used by businesses that are no longer viable or individuals with limited income and substantial debts. Unlike Chapter 11 or Chapter 13 bankruptcies, Chapter 7 does not involve a repayment plan, and businesses filing under Chapter 7 usually cease operations. The process is overseen by a court-appointed trustee, who is responsible for liquidating the debtor’s non-exempt assets, paying creditors, and ensuring compliance with bankruptcy laws.

Common Causes of Business Bankruptcy

Chapter 7 bankruptcy, or liquidation bankruptcy, is often the final step for businesses unable to overcome financial distress. One major cause is excessive debt, where high liabilities outpace a company’s ability to generate income, as seen with Circuit City. Similarly, declining revenues and changing market demand, like in the case of Toys “R” Us, can leave businesses unable to cover costs.

Poor financial management and high fixed costs, such as rent and payroll, exacerbate financial strain, especially during economic downturns or external shocks like the COVID-19 pandemic. Legal liabilities, such as lawsuits or fines, can also overwhelm a business, forcing liquidation.

Companies failing to adapt to technological disruption, like Blockbuster, or those affected by supply chain issues, risk bankruptcy as they lose competitive footing. Additionally, overexpansion without proper financial controls often depletes resources, leading to insolvency.

Chapter 7 highlights the importance of managing debt, adapting to market changes, and planning for risks to avoid liquidation and ensure business longevity.

Excessive Debt and Overleveraging: Businesses with high levels of debt relative to income often struggle to meet financial obligations, especially if revenue declines. Excessive borrowing, particularly during growth phases, can leave companies vulnerable during economic downturns.

Declining Revenues and Market Demand: A sustained drop in sales or market demand, often due to changing consumer preferences, technological disruption, or increased competition, can cripple a business. With insufficient revenue, businesses cannot cover fixed costs like rent, utilities, and payroll.

Poor Financial Management: Mismanagement of finances, such as inadequate cash flow planning, overinvestment in non-essential assets, or failing to monitor costs, can lead to insolvency. Companies that lack strong financial controls often find themselves unable to weather financial challenges.

Economic Downturns and External Shocks: Recessions, pandemics, or unexpected global events can sharply reduce demand, disrupt supply chains, or increase operational costs. Businesses with thin margins or limited reserves are particularly vulnerable.

Legal Liabilities and Litigation: Lawsuits, regulatory fines, or liability claims can create sudden and overwhelming financial burdens for businesses. Legal judgments can lead to asset seizures, leaving businesses unable to continue operations.

High Fixed Costs and Low Profit Margins: Businesses with high fixed costs (e.g., rent, utilities, long-term leases) and narrow profit margins are especially vulnerable to revenue fluctuations. Even small declines in income can create large deficits, leading to insolvency.

Technological Disruption: Companies that fail to adapt to technological advancements or changing industry practices often lose competitiveness, leading to financial decline. Industries undergoing rapid innovation can quickly make certain business models obsolete.

Lack of Access to Financing: Businesses that cannot secure financing or additional credit to address cash flow issues often resort to Chapter 7. Inability to refinance debt or raise capital can leave businesses unable to meet obligations.

Supply Chain Issues: Disruptions in the supply chain, such as rising costs, delays, or shortages, can increase expenses or reduce product availability, causing financial distress. This is particularly true for businesses reliant on just-in-time inventory systems.

Overexpansion: Rapid expansion without sufficient market analysis or operational capacity often leads to cash flow issues and increased debt. Overestimating demand or investing heavily in new locations can stretch resources thin.

Key Steps in a Chapter 7 Filing

Filing the Petition – The bankruptcy process begins with the debtor filing a Chapter 7 petition in federal bankruptcy court. This petition includes a comprehensive list of all assets, liabilities, income, expenses, and a statement of financial affairs. By filing, the business immediately gains protection from creditors under an automatic stay, preventing further collection actions.

Appointment of a Trustee – After the petition, the court appoints a bankruptcy trustee to oversee the liquidation. The trustee’s role includes managing the debtor’s estate, reviewing asset and liability documentation, and identifying assets eligible for liquidation. The trustee is also responsible for maximizing asset recovery to distribute funds to creditors fairly.

Asset Liquidation and Debt Discharge – The trustee liquidates the non-exempt assets of the business, such as inventory, equipment, and property. Assets are prioritized based on secured and unsecured creditor claims, following a hierarchy established by bankruptcy law. Generally, secured creditors are paid first, followed by priority and unsecured creditors. In most cases, unsecured creditors recover only a fraction of their claims—often below 10%—due to limited available assets. Once assets are distributed, the business’s unsecured debts are discharged, meaning the company is no longer obligated to repay them. This final step formally closes the business, and the entity is typically dissolved.

Implications for Businesses and Creditors

The following are the implications for the businesses and other stakeholders as a result of Chapter 7 bankruptcies –

Pros:

Debt Relief: Business owners are released from most unsecured debts, allowing them to move forward without remaining financial burdens from the insolvent entity.

Simplified Process: Chapter 7 is relatively fast and straightforward compared to Chapter 11, typically concluding within 3-6 months. This timeframe provides a more immediate resolution for both owners and creditors.

Lower Costs: With less need for ongoing legal and operational expenses, Chapter 7 is more cost-effective.

Cons:

Loss of Control: Business owners lose all control of the entity and its assets once the trustee is appointed, limiting their role in decision-making and asset management.

No Future Operations: Chapter 7 results in the closure of the business, removing the opportunity for restructuring or reorganization.

Negative Credit Impact: Owners may face challenges in securing future financing due to the adverse impact on their credit.

Circuit City – A Lesson in Chapter 7 Bankruptcy

Background

Circuit City, founded in 1949, was once a leading electronics retailer in the United States, with over 700 stores and 34,000 employees at its peak. The company was renowned for its innovative approach to retail and customer service, being among the first to adopt superstore formats for consumer electronics. However, by the late 2000s, Circuit City found itself struggling in an increasingly competitive market.

Causes of Financial Collapse

Circuit City’s road to Chapter 7 bankruptcy was marked by several critical missteps and external pressures:

Strategic Mismanagement:

The company attempted to cut costs by eliminating 3,400 of its most experienced sales associates in 2007. This move alienated customers, as less knowledgeable staff were unable to provide the high-quality service that was a hallmark of Circuit City’s brand.

Circuit City also failed to embrace e-commerce aggressively, losing significant market share to competitors like Amazon and Best Buy.

Economic Pressures: The 2008 financial crisis led to a sharp decline in consumer spending, particularly on non-essential items like electronics. Circuit City, already facing financial strain, was hit hard by reduced foot traffic and declining revenues.

Overexpansion and High Fixed Costs: The company had expanded aggressively, opening numerous stores that failed to generate sufficient revenue. This left Circuit City burdened with high lease costs and operational expenses.

Poor Inventory Management: Circuit City struggled with inventory issues, frequently stocking items that were outdated or not in demand. This created significant inefficiencies in cash flow and customer satisfaction.

Filing for Bankruptcy

On November 10, 2008, Circuit City filed for Chapter 11 bankruptcy, intending to restructure its debts and remain operational. However, the reorganization efforts failed for several reasons:

The company was unable to secure adequate financing to support operations during the bankruptcy process.

Suppliers became wary of Circuit City’s ability to pay and began restricting credit terms, creating inventory shortages during the crucial holiday shopping season.

Attempts to find a buyer or merger partner were unsuccessful.

By January 16, 2009, Circuit City announced it would close all its remaining stores and transition to Chapter 7 bankruptcy. The decision marked the end of Circuit City’s 60-year legacy.

The Liquidation Process

Under Chapter 7, a court-appointed trustee oversaw the liquidation of Circuit City’s assets. Key steps included:

Selling Inventory: The company conducted massive clearance sales, liquidating its electronics stock at deep discounts.

Auctioning Real Estate: Store leases and properties were auctioned to recover funds for creditors.

Distributing Proceeds: Proceeds from the liquidation were distributed to creditors based on bankruptcy priority rules:
- Secured Creditors: Received most of the proceeds, as their claims were backed by collateral (e.g., store leases, equipment).
- Unsecured Creditors: Received only a small fraction of their claims, reflecting the risks of unsecured lending.
- Shareholders: As is typical in Chapter 7 cases, shareholders received nothing.

Impact on Stakeholders

Employees: Over 34,000 employees lost their jobs, highlighting the human cost of liquidation bankruptcies. Many workers did not receive severance pay, sparking debates about labour protections in bankruptcy law.

Suppliers: Circuit City’s failure left many suppliers with unpaid invoices, creating ripple effects throughout the electronics supply chain.

Competitors: Circuit City’s exit from the market allowed competitors like Best Buy to capture a larger share of the consumer electronics market, reinforcing the importance of strategic agility in competitive industries.

Lessons Learned

The Circuit City case offers valuable lessons for students and professionals analysing Chapter 7 bankruptcies:

Customer Experience Matters: Cost-cutting measures that compromise customer satisfaction can have long-term consequences, especially in competitive industries.

Adaptation is Crucial: Failure to embrace e-commerce and innovate in response to changing consumer preferences sealed Circuit City’s fate.

Cash Flow is King: Poor inventory management and inability to secure financing during bankruptcy underscored the importance of liquidity for survival.

Chapter 7 as a Last Resort: Circuit City’s transition from Chapter 11 to Chapter 7 illustrates the challenges of restructuring without a strong operational and financial foundation.

Chapter 7 vs Chapter 11 Bankruptcies: Insights on the Distinction between Liquidations & Reorganizations

December 24, 2024December 18, 2024 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2025) explores the complexities of Chapter 7 and Chapter 11 bankruptcy laws in the United States, examining how these legal processes impact businesses facing financial distress. With insights into liquidation (Chapter 7) and reorganization (Chapter 11), this post provides a detailed overview of each chapter’s purpose, process, and strategic implications, offering valuable lessons in managing debt and financial recovery.

Bankruptcy Basics

Bankruptcy is a legal framework that helps individuals and businesses unable to meet their financial obligations. When a company files for bankruptcy, it either seeks to reorganize its debts and operations or liquidate its assets to repay creditors, depending on the type of bankruptcy pursued (Chapter 7 or Chapter 11 procedures in US bankruptcy law). Over 30,000 businesses filed for bankruptcy in the US in 2023, demonstrating the critical role this process plays in managing corporate distress. Bankruptcy can offer a pathway to stability, enabling companies to mitigate debt burdens, restructure, and potentially preserve jobs.

1. General Motors (2009) – Corporate Example

Background: General Motors (GM), one of the largest automobile manufacturers, faced a severe financial crisis in 2009. With declining sales, a massive debt load, and high operational costs, GM was unable to meet its financial obligations.

Bankruptcy Filing: GM filed for Chapter 11 bankruptcy to reorganize its debts. Through the bankruptcy framework, GM was able to reduce its liabilities, renegotiate labour contracts, and streamline operations, ultimately emerging as a more financially sustainable company.

Outcome: The bankruptcy framework allowed GM to reorganize its operations and avoid liquidation, protecting jobs and enabling it to continue as a key player in the automotive industry.

2. Lehman Brothers (2008) – Corporate Example

Background: Lehman Brothers, a global financial services firm, was heavily leveraged and exposed to subprime mortgage debt. When the real estate market collapsed, Lehman was unable to meet its debt obligations.

Bankruptcy Filing: Lehman filed for Chapter 11 bankruptcy, marking one of the largest corporate bankruptcies in history. The legal framework allowed Lehman to begin asset liquidation and distribute proceeds to creditors under court supervision.

Outcome: Though Lehman did not emerge as a reorganized company, the bankruptcy framework facilitated an orderly process for winding down the firm and managing creditor claims, preventing a more chaotic collapse.

3. Curtis James Jackson III (50 Cent) – Personal Bankruptcy Example

Background: The rapper and entrepreneur Curtis Jackson (known as 50 Cent) filed for Chapter 11 bankruptcy in 2015 after facing lawsuits and substantial debts he could not pay.

Bankruptcy Filing: Chapter 11 allowed Jackson to reorganize his debts without liquidating his assets entirely. He was able to negotiate repayment terms with creditors while continuing his business ventures.

Outcome: Through the bankruptcy framework, Jackson completed a reorganization plan, ultimately repaying creditors over time and successfully emerging from bankruptcy while preserving his business interests.

Legal Definition and Purpose

The U.S. Bankruptcy Code is a comprehensive set of federal laws enacted to provide a legal framework for bankruptcy filings. It is codified in Title 11 of the United States Code and governs all bankruptcy cases in the country, with different chapters addressing various types of financial distress.

The Code’s objectives include ensuring a fair distribution of the debtor’s assets among creditors, offering a fresh start to debtors, and establishing a structured process for both liquidation and reorganization. The Bankruptcy Code covers everything from the types of bankruptcy filings available to the specific steps and criteria needed for each process. All bankruptcy cases are overseen by federal bankruptcy courts, with judges responsible for ensuring compliance with the Code and adjudicating disputes between debtors and creditors.

Legally, bankruptcy is a federal judicial process governed by the U.S. Bankruptcy Code, which provides the framework to address insolvent companies’ financial liabilities. The primary purposes of bankruptcy law are:

Fair and Equitable Treatment of Creditors: Bankruptcy law ensures that creditors are repaid as fairly as possible based on their claims and priorities.

Relief and Protection for the Debtor: Filing for bankruptcy gives businesses temporary relief from creditor actions, such as lawsuits and collections, allowing them to reorganize or liquidate assets without external pressure.

Rehabilitation or Exit from Market: Depending on the situation, bankruptcy provides businesses with the opportunity to restructure and regain stability or exit the market responsibly.

In practice, bankruptcy serves as both a shield and a tool, giving companies the time and resources to evaluate and act on their financial situation in a structured manner.

Common Causes of Business Bankruptcy

Businesses typically face bankruptcy due to a mix of internal and external factors. Key factors include:

Poor Financial Management: Mismanagement of finances, including high debt levels and inadequate cash flow, is a primary cause. About 50% of small businesses fail within the first five years, often due to financial missteps.

Economic Downturns: Recessions and economic instability can severely impact sales and profit margins, leaving companies unable to meet their financial obligations. The COVID-19 pandemic saw a 20% increase in business bankruptcies in specific sectors, especially retail and hospitality.

High Debt Obligations: When companies rely too heavily on borrowed capital, downturns can leave them unable to service their debt, resulting in financial distress.

Industry Disruptions: Changes in technology and consumer preferences can render a business model obsolete, pushing companies toward bankruptcy. For example, retailers like Sears and J.C. Penney filed for bankruptcy as online shopping trends transformed the retail landscape.

Legal and Regulatory Challenges: Companies in highly regulated industries, such as healthcare and finance, may face significant legal and compliance costs, which can lead to bankruptcy if they are not adequately prepared.

Differences between Chapter 7 & Chapter 11 Bankruptcies

The table below presents the differences between Chapter 7 (liquidation) and Chapter 11 (reorganization) procedures in the US bankruptcy law:

When to opt for Liquidation (Chapter 7) vs. Reorganization (Chapter 11)

Choosing between Chapter 7 liquidation and Chapter 11 reorganization is a pivotal decision for distressed businesses. This choice hinges on various strategic, financial, and operational factors that impact not only the business’s future but also creditors, employees, and shareholders.

Liquidation (Chapter 7)

Ideal Situations for Liquidation:

No Path to Profitability: If a business has no viable path to profitability due to declining industry demand, obsolete products, or irreparable operational inefficiencies, Chapter 7 might be the optimal choice. For example, Circuit City, a major electronics retailer, filed for Chapter 7 in 2009 after failing to adapt to e-commerce trends. With revenue losses of nearly 20% year-over-year and no viable turnaround options, liquidation was chosen to maximize asset value.

Severe Debt Burden: When a business’s debt load is unsustainable and far exceeds its asset value, liquidation might offer the highest recovery rate for creditors. Companies in this position often have debts that are difficult to renegotiate, and without sufficient cash flow to cover interest and principal payments, they are left with no restructuring options.

Asset-Heavy Businesses: Companies with valuable physical assets may benefit more from Chapter 7, where assets like real estate, equipment, and inventory can be sold to partially satisfy creditors. For instance, Toys “R” Us converted to Chapter 7 in 2018, liquidating $1 billion in inventory and assets to repay secured creditors when reorganization proved unfeasible.

Advantages of Chapter 7:

Speed of Resolution: Chapter 7 cases typically conclude within 3 to 6 months, allowing for a quicker closure and reducing prolonged financial strain.

Lower Costs: Compared to Chapter 11, Chapter 7 has lower administrative and legal fees, with an estimated cost between $20,000 and $50,000 for small to medium-sized businesses, whereas Chapter 11 often involves significant legal expenses.

Reorganization (Chapter 11)

Ideal Situations for Reorganisation:

Operational Viability: If a business has strong core operations but is experiencing temporary financial setbacks, Chapter 11 reorganization allows for restructuring while continuing operations. American Airlines, which filed for Chapter 11 in 2011 with over $40 billion in liabilities, was able to reduce labour costs, restructure debt, and emerge stronger through a merger with US Airways.

Need for Asset Preservation: Businesses with valuable intangible assets, such as patents, brands, or customer relationships, can benefit from Chapter 11 to maintain their brand value and market share. Hertz, the global rental car giant, used Chapter 11 in 2020 to retain its market position and shed $5 billion in debt while reorganizing, eventually re-emerging with a stronger balance sheet.

Possibility of Financing and Restructuring: Companies that can attract post-petition financing and renegotiate debts stand a better chance in Chapter 11. Lenders are often more willing to provide financing if the company has a solid plan and ongoing revenue streams. For instance, General Motors secured $30 billion in federal aid during its 2009 Chapter 11 process, allowing it to restructure and continue operations.

Advantages of Chapter 11:

Long-Term Viability: Chapter 11 provides companies with the time and flexibility to reorganise their debts and adjust operations, potentially leading to sustainable profitability.

Creditor Negotiation: Chapter 11 allows debtors to negotiate with creditors for more favourable repayment terms, often resulting in higher recovery rates for unsecured creditors compared to Chapter 7.

Case Study: Toys “R” Us

In 2018, the iconic toy retailer Toys “R” Us filed for Chapter 7 bankruptcy, transitioning from an initial Chapter 11 reorganization filing. The bankruptcy marked one of the most significant retail closures in recent history, affecting 33,000 employees and closing over 700 stores in the U.S. alone.

Background and Context

Company Overview:

Founded: 1948

Industry: Retail (Specialty Toy and Baby Products)

Global Reach: Operated over 1,600 stores worldwide at its peak, including over 700 stores in the U.S.

Legacy: Toys “R” Us was one of the largest toy retailers globally and an iconic brand for several generations.

Financial Background:

Debt Load: Carried approximately $5 billion in debt, primarily from a leveraged buyout (LBO) in 2005 by private equity firms. This debt created a significant financial burden, consuming profits and limiting the company’s ability to reinvest in modernization efforts.

Revenue Pressures: Struggled to compete with e-commerce giants like Amazon and low-cost retailers like Walmart, which offered competitive pricing and convenience.

Initial Bankruptcy Filing (Chapter 11):

Date: September 2017

Objective: The initial Chapter 11 filing was intended to restructure debts and revive the company’s operations. Toys “R” Us aimed to reduce its debt load and improve liquidity to invest in a digital presence and update store experiences.

Challenges: Despite the plan, Toys “R” Us could not generate sufficient revenue to cover operational and restructuring costs due to stiff online competition, seasonal sales dependency, and lack of investor confidence.

Transition to Chapter 7 (Liquidation)

Reasons for Conversion:

Failed Restructuring: By early 2018, the restructuring under Chapter 11 was unsuccessful. The company faced critical cash flow issues and was unable to secure the financing needed to support the reorganization.

Market Challenges: The rise of e-commerce, coupled with consumer preferences shifting away from physical stores, reduced Toys “R” Us’s competitive advantage and viability.

Debt Burden: Servicing a high debt load further strained finances, with Toys “R” Us spending millions annually in interest payments, limiting funds available for reinvestment.

Decision:

Date: March 2018

Outcome: Toys “R” Us officially filed for Chapter 7, leading to the closure and liquidation of its U.S. stores and operations. The transition marked the end of its efforts to survive as a going concern.

The Liquidation Process

Role of the Trustee:

A trustee was appointed to oversee the liquidation of Toys “R” Us’s assets. The trustee’s duties included identifying and valuing assets, conducting sales, and distributing proceeds to creditors based on a priority system.

Assets Liquidated:

Inventory and Merchandise: All remaining toy inventory and other merchandise were liquidated through clearance sales.

Real Estate: Store leases and property rights were sold, with some locations acquired by competitors or other businesses.

Intellectual Property: The “Toys “R” Us” brand, Geoffrey the Giraffe mascot, and other trademarks were sold to generate additional revenue.

Outcome:

Total Proceeds: The liquidation generated approximately $1 billion, but this amount was insufficient to cover the $5 billion debt load fully.
Creditors’ Recovery: Due to the liquidation hierarchy:

Secured Creditors: Received a higher percentage of their claims, as their loans were backed by collateral.

Unsecured Creditors: Recovered less than 5% of their initial investments, reflecting the typical outcome for unsecured claims in Chapter 7 cases.

Impact on Stakeholders

Employees: Approximately 33,000 employees lost their jobs, sparking national debates on the treatment of workers in corporate bankruptcies. Many workers did not receive severance pay, leading to calls for legislative reform in corporate bankruptcy processes.

Suppliers and Partners: Suppliers faced unpaid invoices and significant losses due to the liquidation. The bankruptcy also created ripple effects in the toy industry, impacting toy manufacturers reliant on Toys “R” Us as a major retailer.

Community and Local Economy: The closure of over 700 stores in the U.S. led to economic downturns in local communities, where Toys “R” Us had served as a major employer and contributor to commercial activity.

Key Lessons and Takeaways

1. High Leverage Risks:

The leveraged buyout in 2005 saddled Toys “R” Us with an unsustainable debt load, diverting critical funds toward interest payments instead of innovation and digital transformation.

Insight: Businesses in highly competitive industries should maintain manageable debt levels, particularly when rapid market shifts (like e-commerce growth) threaten traditional business models/

2. Market Adaptation and Innovation:

Toys “R” Us struggled to adapt to changing consumer behaviour, as shoppers increasingly turned to online platforms. The failure to invest in e-commerce further weakened the company’s market position.
Insight: Businesses must continuously invest in technology and customer experience to remain relevant, particularly in the retail sector where consumer preferences shift rapidly.

3. Stakeholder Impact in Chapter 7:

The liquidation resulted in minimal recoveries for unsecured creditors and severe job losses, highlighting the often-painful impact of Chapter 7 on stakeholders.
Insight: Chapter 7 filings may serve as a stark reminder for stakeholders about the importance of financial due diligence and credit protections when engaging with highly leveraged companies.

4. Corporate Governance and Accountability:

The Toys “R” Us case spurred debates on corporate governance, particularly regarding the responsibilities of private equity owners in highly leveraged companies. Questions were raised about whether the company could have been saved with better financial management.
Insight: Effective corporate governance, with a focus on sustainable financing and operational resilience, is essential for long-term business health.

My Experience as a Customer Finance & Credit Risk Analyst at Airbus

During my time as a Customer Finance & Credit Risk Analyst at Airbus, which was part of my Master in Management degree at ESSEC Business School, I had the opportunity to play a pivotal role in leading financial analyses and supporting high-stakes deal campaigns in the aviation sector. This experience was instrumental in sharpening my analytical and credit risk assessment capabilities, as I worked on transactions exceeding €200M, where each decision carried significant financial implications.

In this role, I focused on developing advanced financial models and internal customer credit rating models, applying methodologies from major credit rating agencies like Moody’s, S&P, and Fitch. These models, built using tools such as Excel, R, and Python, allowed my team to improve the accuracy of risk predictions for over 200 global client companies (mostly airline companies) air. By conducting industry-wide credit risk analyses, I ensured that each deal was supported by a thorough understanding of financial and credit health, helping Airbus mitigate risks and seize opportunities in a highly competitive market.

A key highlight of my work involved analysing the impact of M&A and restructuring activities within the aviation industry. This hands-on experience further honed my ability to deliver comprehensive financial forecasts and credit risk analyses.

One of the most rewarding aspects of my role was the opportunity to present these financial insights directly to senior executives. Communicating complex financial data effectively is crucial when high-value transactions are involved, and this responsibility significantly enhanced my presentation and communication skills. My experience in presenting to top executives helped me not only translate data into actionable strategies but also contributed to the decision-making process at the highest level.

Overall, my role as a Customer Finance & Credit Risk Analyst at Airbus was a formative experience that deepened my expertise in financial modelling, credit risk analysis, and strategic financial communication. It was an invaluable opportunity to contribute to significant aviation industry deals and refine my skills in evaluating financial performance and credit health at a global scale.

Process Automation and Efficiency Improvement: Leading the automation of the internal credit rating system taught me how to streamline workflows and improve efficiency, significantly reducing the time spent on manual processes while enhancing data accuracy.

Concepts related my Apprenticeship

I explain below three business concepts related my apprenticeship: value chain, credit risk analysis, and financial ratios.

Value Chain

The commercial aviation sector comprises multiple interconnected players, each contributing to different stages of the value chain. The value chain begins with aircraft Original Equipment Manufacturers (OEMs) like Airbus and Boeing, which design and manufacture aircraft. These OEMs negotiate deal terms with airlines and lessors for the sale or lease of aircraft. The deals can range from firm orders, where aircraft are purchased outright, to leasing agreements, where airlines lease aircraft for operational flexibility.

In this value chain, airlines are the primary end users, operating the aircraft to transport passengers (commercial airplane) and freight (cargo airplane). Lessors act as intermediaries, purchasing aircraft from OEMs and leasing them to airlines, offering flexibility in fleet management. Additionally, Maintenance, Repair, and Overhaul (MRO) providers play a critical role in ensuring the safety and performance of aircraft throughout their lifecycle. Financial institutions and credit rating agencies are also integral players, assessing the creditworthiness of the companies involved and financing large-scale aircraft transactions.

The deal-signing process with OEMs often involves complex negotiations on pricing, delivery schedules, and terms of financing. Types of deals include sale agreements, wet or dry leases, and purchase options. The financial arrangements and credit risk evaluations play a pivotal role in securing these deals, ensuring that all parties can fulfil their obligations over the aircraft’s operational life.

Credit Risk Analysis

Credit risk analysis is the process of evaluating the likelihood that a borrower or counterparty will default on their financial obligations. In the context of my work at Airbus, credit risk analysis was crucial for understanding the financial health of customers—whether they were airlines, lessors, or MRO service providers. By analysing financial statements, liquidity ratios, and external market factors, we could gauge the risk of default and the overall creditworthiness of these companies.

Credit ratings, provided by the three major credit rating agencies—Moody’s, S&P, and Fitch, are a standardized way to assess a company’s financial health and default risk. These agencies evaluate the financial statements of companies, industry trends, and macroeconomic conditions to assign ratings that range from AAA (lowest risk) to D (in default). Credit ratings are essential for investors and lenders in determining the risk profile of potential investments and for companies like Airbus when structuring deals.

Airbus, like many large corporations, uses internal customer credit rating models alongside external credit ratings to gain deeper insights into the financial stability of its clients. These models allow Airbus to account for industry-specific factors and customer performance metrics that external agencies might overlook. Internal models are particularly valuable in predicting potential risks and making informed decisions about financing, delivery schedules, and long-term contracts, ensuring that Airbus minimizes exposure to credit risk.

Financial Ratios

Financial ratios (key performance indicators (KPIs) for the financial health of a firm) are vital in assessing the financial health of companies in the aviation sector. During my time at Airbus, I focused on analysing these KPIs to evaluate the financial stability and creditworthiness of our customers:

Liquidity Ratios: Indicators like the current ratio and quick ratio show a company’s ability to meet its short-term obligations. A higher ratio suggests stronger liquidity and a lower risk of financial distress.

Debt-to-Equity Ratio: This KPI measures the proportion of debt financing relative to equity. A lower debt-to-equity ratio typically indicates a more financially stable company, with less risk of default in turbulent market conditions.

Profitability Margins: Metrics like net profit margin and EBITDA margin give insights into how efficiently a company is operating. Higher profitability suggests a company can generate sufficient revenue to cover its expenses, even in challenging times.

Gearing Ratio: A company’s gearing ratio measures its financial leverage and how reliant it is on debt to finance its operations. A higher gearing ratio may indicate increased financial risk.

Altman Z-Score: This is a composite score used to predict bankruptcy risk, combining profitability, leverage, liquidity, solvency, and activity ratios. It’s particularly useful for assessing companies under financial stress, a key concern in the aviation sector post-COVID-19.

Cash Flow from Operations: A company’s ability to generate consistent cash flow from its core operations is a strong indicator of financial health. In the aviation sector, where cash flow can be cyclical, maintaining positive cash flow is critical for long-term sustainability.

The following table provides some of the important financial ratios used to estimate the risk of a company. High financial risk is implied by high or low measure according to the ratio.

Litecoin: Analysis of the Pioneering Cryptocurrency’s Impact on Digital Finance

January 5, 2025July 31, 2024 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2024) explains cryptocurrency Litecoin, shedding light on its impact and value propositions for digital finance.

Historical context and background

Litecoin, often referred to as the “silver to Bitcoin’s gold,” emerged in 2011 as one of the earliest altcoins, or alternative cryptocurrencies, following the launch of Bitcoin in 2009. It was created by Charlie Lee, a former Google engineer and Coinbase employee. Lee designed Litecoin with the intention of addressing some of the perceived limitations of Bitcoin, such as transaction speed and scalability.

One of the key innovations of Litecoin was its adoption of the Scrypt hashing algorithm instead of Bitcoin’s SHA-256 algorithm. This choice made Litecoin more accessible to individual miners using consumer-grade hardware, as it reduced the advantage of specialized mining equipment known as ASICs (Application-Specific Integrated Circuits). As a result, Litecoin initially gained popularity among miners and enthusiasts who sought a more democratic and decentralized mining ecosystem.

Litecoin also introduced a faster block generation time compared to Bitcoin, with new blocks being created approximately every 2.5 minutes instead of every 10 minutes. This faster block time enabled quicker transaction confirmations, making Litecoin more suitable for everyday transactions.

Over the years, Litecoin has established itself as one of the most prominent cryptocurrencies in the market, often considered a reliable and stable digital asset. Its longevity and consistent development have contributed to its reputation as a credible alternative to Bitcoin.

Litecoin’s journey has been marked by various milestones, including network upgrades, partnerships, and integrations into payment systems and exchanges. Despite facing competition from other cryptocurrencies and undergoing market fluctuations, Litecoin has maintained a strong community of supporters and continues to be actively traded and utilized for various purposes, including payments, remittances, and investment.

Key features

Scrypt Algorithm

Unlike Bitcoin’s SHA-256 algorithm, Litecoin utilizes the Scrypt hashing algorithm for its proof-of-work consensus mechanism. This algorithm was chosen to enable faster block generation and to promote more decentralized mining by reducing the advantage of specialized mining hardware (Application-Specific Integrated Circuits (ASIC) versus consumer-grade hardware like standard PCs).

Faster Block Time

Litecoin has a target block time of approximately 2.5 minutes, compared to Bitcoin’s 10 minutes. This faster block time allows for quicker transaction confirmations, making Litecoin more suitable for everyday transactions.

Higher Maximum Coin Supply

Litecoin has a maximum coin supply limit of 84 million coins, four times the maximum supply of Bitcoin. This larger supply aims to facilitate more widespread adoption and usage while still maintaining scarcity.

Segregated Witness (SegWit) Activation

Litecoin was one of the first major cryptocurrencies to activate Segregated Witness (SegWit), a protocol upgrade aimed at improving transaction throughput and scalability. SegWit also paved the way for the implementation of the Lightning Network on Litecoin, enabling off-chain transactions for faster and cheaper payments.

Atomic Swaps

Litecoin has been at the forefront of implementing Atomic Swaps, a technology that allows for the trustless exchange of cryptocurrencies across different blockchains without the need for intermediaries like crypto platforms. This feature enhances interoperability and decentralization within the cryptocurrency ecosystem.

Litecoin Improvement Proposals (LIPs)

Similar to Bitcoin Improvement Proposals (BIPs), Litecoin has its own proposal system called Litecoin Improvement Proposals (LIPs). These proposals allow community members to suggest changes or improvements to the Litecoin protocol, fostering a transparent and collaborative development process.

Use cases

Peer-to-Peer Payments

Litecoin’s fast transaction confirmations and low fees make it suitable for peer-to-peer transactions. Users can quickly send and receive funds across the globe without relying on traditional banking systems, making Litecoin an efficient option for remittances and international payments.

Online Purchases

As of 2023, over 2,000 online merchants and service providers accept Litecoin as a form of payment globally. Litecoin’s transaction volume has steadily increased, with an average of over 100,000 transactions per day. In 2022, Litecoin processed over 35 million transactions, highlighting its growing use for everyday payments. Many online merchants and service providers accept Litecoin as a form of payment. There are over 5,000 cryptocurrency ATMs worldwide that support Litecoin, allowing users to buy and sell LTC with cash. Users can use Litecoin to purchase a wide range of goods and services, including electronics, clothing, digital products, and more.

Micropayments

Litecoin’s low transaction fees and fast processing times make it well-suited for micropayments, enabling users to make small transactions economically. This use case is particularly relevant for content creators, online tipping, and pay-per-view services.

Cross-Border Transactions

Litecoin’s borderless nature makes it an attractive option for cross-border transactions, as users can avoid the high fees and long processing times associated with traditional remittance services and bank transfers.

Privacy Transactions

While not as focused on privacy as some other cryptocurrencies like Monero or Zcash, Litecoin offers a degree of privacy through features like confidential transactions and the option to use privacy-enhancing wallets. This makes Litecoin appealing for users who prioritize privacy in their transactions.

Technology and underlying blockchain

Litecoin operates on a blockchain-based decentralized network, sharing many similarities with Bitcoin while incorporating several key technical differences. At its core, Litecoin’s blockchain serves as a distributed ledger that records all transactions made with its native cryptocurrency, LTC. One of the distinguishing features of Litecoin is its utilization of the Scrypt proof-of-work algorithm, which differs from Bitcoin’s SHA-256 algorithm. This algorithm was chosen to promote a more equitable mining process, allowing individuals to mine LTC using consumer-grade hardware and reducing the dominance of specialized mining equipment.

The Litecoin blockchain maintains a target block time of approximately 2.5 minutes, significantly faster than Bitcoin’s 10-minute block time. This faster block generation rate enables quicker transaction confirmations, making Litecoin well-suited for use in everyday transactions and enhancing its scalability. Additionally, Litecoin implemented Segregated Witness (SegWit) in 2017, a protocol upgrade aimed at improving transaction throughput and reducing network congestion by separating transaction signatures from transaction data.

Furthermore, Litecoin has experimented with technologies like the Lightning Network, a layer-2 scaling solution designed to facilitate instant and low-cost transactions by leveraging payment channels. This technology enables off-chain transactions that can be settled on the Litecoin blockchain, further enhancing its transaction speed and efficiency.

Supply of coins

Figure Figure 2. Litecoin Supply

Source: Yahoo! Finance.

Litecoin’s coin supply is governed by its protocol, which dictates the issuance rate and maximum supply limit. Unlike traditional fiat currencies that are subject to centralized control by governments and central banks, Litecoin operates on a decentralized network secured by blockchain technology. The issuance of new Litecoin coins occurs through a process called mining, where miners use computational power to validate transactions and add new blocks to the blockchain.

Litecoin employs a deflationary monetary policy, with a fixed issuance schedule that halves the block reward approximately every four years. Initially, the block reward was set at 50 Litecoins per block, but it reduces by half every 840,000 blocks. This process, known as “halving,” aims to curb inflation over time and maintain scarcity, similar to Bitcoin’s issuance schedule. As of now, the block reward stands at 12.5 Litecoins per block, and this rate will continue to halve periodically until the maximum supply of 84 million Litecoins is reached.

The predictable issuance schedule and maximum supply cap of Litecoin contribute to its scarcity and value proposition, aligning with principles of sound money and monetary decentralization. This transparent and algorithmic approach to coin issuance fosters confidence among users and investors, as it prevents arbitrary inflation and ensures the integrity of Litecoin’s monetary policy over the long term.

BNB’s Journey through the Digital Economy’s Cryptocurrency Landscape

May 15, 2024May 15, 2024 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2024) explains the intricate workings and transformative potential of Binance Coin (BNB), exploring its origins, utility, market dynamics, and future prospects of this cornerstone of the digital economy.

Historical context and background

Binance Coin (BNB) is one of the most prominent cryptocurrencies in the market, known for its unique utility and its connection to the world’s largest cryptocurrency exchange, Binance. Binance, founded by Changpeng Zhao (CZ) in 2017, quickly rose to prominence as one of the leading cryptocurrency exchanges globally. Its rapid growth can be attributed to several factors, including its user-friendly interface, wide range of supported cryptocurrencies, and a robust security system. Binance gained significant traction during the bull run of 2017, becoming the go-to platform for traders and investors seeking to capitalize on the burgeoning cryptocurrency market.

In July 2017, Binance conducted an Initial Coin Offering (ICO) to raise funds for the development of its platform and ecosystem. During the ICO, the exchange issued its native cryptocurrency, Binance Coin (BNB), which operates on the Ethereum blockchain as an ERC-20 token. The ICO was a massive success, raising $15 million within just a few weeks.

BNB was initially designed as a utility token to facilitate transactions on the Binance platform, offering users various benefits such as discounted trading fees and participation in token sales hosted on the exchange. Binance committed to using a portion of its profits to buy back and burn BNB tokens periodically, reducing the overall supply over time and potentially increasing its value.

As Binance continued to expand its services and offerings, the utility of BNB expanded beyond just a means of reducing trading fees. BNB became an integral part of the Binance ecosystem, serving as the native currency for various applications and services, including Binance Launchpad, Binance Smart Chain, Binance DEX (decentralized exchange), and Binance NFT marketplace, among others.

The introduction of Binance Smart Chain (BSC) in 2020 further elevated the importance of BNB in the cryptocurrency space. BSC, a blockchain platform compatible with Ethereum Virtual Machine (EVM), was developed to provide an alternative to Ethereum for decentralized finance (DeFi) applications and decentralized applications (DApps). BNB serves as the native currency of BSC, powering transactions and fueling the ecosystem’s growth.

Key features

Utility Token

BNB was initially designed as a utility token to facilitate transactions on the Binance platform. Users can utilize BNB to pay for trading fees, exchange fees, and various other services offered by Binance.

Discounted Fees

One of the primary benefits of holding BNB on the Binance exchange is the opportunity to receive discounts on trading fees. Binance offers users who pay their trading fees with BNB a significant discount, incentivizing its use within the platform.

Token Burn

Binance commits to using a portion of its profits to buy back and burn BNB tokens regularly. This token burning mechanism reduces the total supply of BNB over time, potentially increasing its scarcity and value.

Multiple Use Cases

BNB has expanded beyond its original utility and is now used for various purposes within the Binance ecosystem. It serves as the native currency for token sales on Binance Launchpad, transaction fees on Binance DEX, and participation in Binance NFT marketplace, among other applications.

Binance Smart Chain (BSC)

BNB is the native cryptocurrency of Binance Smart Chain, a blockchain platform compatible with Ethereum Virtual Machine (EVM). BSC offers low transaction fees and high throughput, making it an attractive option for decentralized applications (DApps) and decentralized finance (DeFi) projects.

Governance

BNB holders have the opportunity to participate in the governance of the Binance ecosystem. They can vote on proposals and decisions related to the development and direction of Binance, providing a degree of decentralization and community involvement.

Staking and Yield Farming

BNB holders can participate in staking and yield farming programs, allowing them to earn rewards or yield by locking up their BNB tokens and contributing to the security and operation of the network.

Use cases

Participation in Token Sales

BNB holders often have exclusive access to token sales hosted on the Binance Launchpad platform. These sales allow users to invest in promising blockchain projects at an early stage, with BNB serving as the primary currency for participation.

Payment Method

BNB can be used as a payment method for various goods and services, both online and offline. Several merchants and businesses accept BNB as a form of payment, enabling users to utilize their cryptocurrency holdings for everyday transactions.

Binance Ecosystem Services

BNB is utilized within various services and applications offered by the Binance ecosystem. This includes decentralized finance (DeFi) protocols, decentralized exchanges (DEXs), non-fungible token (NFT) marketplaces, and more. BNB serves as the native currency for transactions, governance, and incentives within these platforms.

Cross-Chain Compatibility

With the introduction of Binance Smart Chain (BSC), BNB gained cross-chain compatibility, enabling it to be used in decentralized applications (DApps) and DeFi protocols across different blockchain networks. This expansion of utility enhances the interoperability and flexibility of BNB as a cryptocurrency.

Technology and underlying blockchain

Binance Coin (BNB) operates on two primary blockchain networks: the Ethereum blockchain and the Binance Smart Chain (BSC). Initially launched as an ERC-20 token on the Ethereum blockchain, BNB has since undergone a significant expansion with the introduction of the Binance Smart Chain. The Ethereum-based BNB tokens are utilized for various functions within the Binance ecosystem, including trading fee discounts, participation in token sales, and payments. However, to address scalability and transaction cost concerns, Binance developed the Binance Smart Chain, a parallel blockchain compatible with Ethereum Virtual Machine (EVM). BSC combines high performance with low transaction fees, offering a viable alternative for decentralized applications (DApps) and decentralized finance (DeFi) protocols. BNB serves as the native currency of BSC, facilitating transactions, powering smart contracts, and providing liquidity across the Binance Smart Chain ecosystem. BSC employs a proof-of-stake (PoS) consensus mechanism, where validators stake BNB to secure the network and validate transactions. This hybrid approach leverages the benefits of both decentralization and efficiency, making BNB and the Binance Smart Chain integral components of the rapidly evolving blockchain landscape.

Supply of coins

The total supply of Binance Coin (BNB) is capped at 200 million tokens. However, BNB’s initial distribution was structured to release a portion of this supply gradually over time. During its initial coin offering (ICO) in July 2017, Binance allocated 50% of the total token supply to the public sale, representing 100 million BNB tokens. The remaining 50% was split among the Binance team, early investors, and strategic partners, with a significant portion earmarked for ecosystem development and marketing efforts. Notably, Binance committed to periodic token burns, where a portion of BNB tokens used to pay for trading fees on the Binance exchange is systematically removed from circulation and permanently destroyed. These token burns serve to reduce the overall supply of BNB over time, potentially increasing its scarcity and value. As of [current date], multiple token burns have occurred, steadily decreasing the circulating supply of BNB and contributing to its deflationary nature. Additionally, BNB’s migration from the Ethereum blockchain to its own blockchain, Binance Chain, introduced a new mechanism for token issuance and governance, further shaping the supply dynamics of BNB within the Binance ecosystem.

Cardano: Exploring the Future of Blockchain Technology

May 6, 2024May 6, 2024 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2024) explains the cryptocurrency Cardano.

Historical context and background

Cardano is a blockchain platform that was founded in 2017 by Charles Hoskinson, one of the co-founders of Ethereum. The project was initiated by Input Output Hong Kong (IOHK), a technology company focused on blockchain and cryptocurrency. Cardano’s development was guided by a scientific philosophy and peer-reviewed research, aiming to create a more scalable, sustainable, and interoperable blockchain platform. Cardano is named after Gerolamo Cardano, the Italian mathematician, whereas the cryptocurrency associated with the platform is named after Ada Lovelace, the English mathematician.

Cardano distinguishes itself through its layered architecture, which separates the platform’s settlement layer (Cardano Settlement Layer, CSL) from its computation layer (Cardano Computation Layer, CCL). This separation allows for greater flexibility and scalability, as well as easier implementation of updates and improvements.

Another notable feature of Cardano is its consensus mechanism, called Ouroboros, which is based on a proof-of-stake algorithm. Ouroboros aims to achieve both security and scalability by allowing users to participate in the consensus process based on the amount of cryptocurrency they hold, rather than requiring expensive computational resources like Bitcoin’s proof-of-work mechanism.

Cardano’s development has been divided into phases, each focusing on different aspects of the platform’s functionality and features. These phases include Byron (foundation), Shelley (decentralization), Goguen (smart contracts), Basho (scaling), and Voltaire (governance). As of the time of writing, Cardano has successfully completed the Byron and Shelley phases, with ongoing work on the Goguen phase, which will enable the implementation of smart contracts and decentralized applications (dApps) on the platform.

Key features

Layered Architecture

Cardano’s architecture is divided into two layers – the Cardano Settlement Layer (CSL) and the Cardano Computation Layer (CCL). This separation allows for greater flexibility, scalability, and easier implementation of updates and improvements.

Ouroboros Consensus Protocol:

Cardano uses the Ouroboros proof-of-stake consensus algorithm, which is designed to be secure, scalable, and energy-efficient. It allows users to participate in the consensus process based on the amount of cryptocurrency they hold, rather than requiring expensive computational resources.

Scalability

Cardano is designed to be highly scalable, capable of handling a large number of transactions per second. Through its layered architecture and consensus mechanism, Cardano aims to achieve scalability without sacrificing security or decentralization.

Interoperability

Cardano aims to enable interoperability between different blockchain networks and protocols. This will allow for seamless transfer of assets and data between different platforms, facilitating greater connectivity and usability of decentralized applications (dApps).

Smart Contracts

Cardano is developing support for smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. Smart contracts will enable the creation of decentralized applications (dApps) on the Cardano platform, opening up a wide range of possibilities for developers and users.

Governance

Cardano has a built-in governance mechanism that allows stakeholders to participate in the decision-making process for the future development of the platform. This includes voting on proposals for protocol upgrades, funding development projects, and other governance-related decisions.

Formal Verification

Cardano emphasizes formal methods and peer-reviewed research in its development process. This includes using formal verification techniques to ensure the correctness and security of its protocols and smart contracts, reducing the risk of bugs and vulnerabilities.

Use cases

Decentralized Finance (DeFi)

Cardano’s smart contract capabilities can facilitate various DeFi applications, including decentralized exchanges (DEXs), lending platforms, stablecoins, and automated market makers (AMMs). Smart contracts on Cardano can enable programmable financial transactions without the need for intermediaries, providing users with greater control over their assets and reducing counterparty risk.

Supply Chain Management

Cardano’s blockchain can be utilized to track and authenticate products throughout the supply chain, ensuring transparency and accountability. By recording every step of a product’s journey on the blockchain, stakeholders can verify its origin, quality, and authenticity, thereby reducing fraud, counterfeiting, and logistical inefficiencies.

Identity Management

Cardano’s blockchain can serve as a secure and decentralized platform for identity management, enabling individuals to control and manage their digital identities without relying on centralized authorities. By leveraging cryptographic techniques, users can securely authenticate themselves and access various services, such as voting, healthcare, and financial transactions, while maintaining privacy and security.

Voting and Governance

Cardano’s blockchain can support transparent and tamper-resistant voting and governance systems, enabling communities to make collective decisions and govern decentralized organizations (DAOs). By using blockchain technology, voting processes can be made more secure, efficient, and auditable, ensuring fair and democratic outcomes.

Tokenization of Assets

Cardano’s blockchain can tokenize various real-world assets, such as real estate, stocks, and commodities, making them easily tradable and transferable on a global scale. By representing assets as digital tokens on the blockchain, ownership rights can be easily verified, fractional ownership can be enabled, and liquidity can be increased, unlocking new opportunities for investment and asset management.

Technology and Underlying Blockchain

Cardano is built on a multi-layered architecture designed to provide scalability, interoperability, and sustainability. At its core, Cardano utilizes a proof-of-stake (PoS) consensus mechanism called Ouroboros, which offers a more energy-efficient and secure alternative to traditional proof-of-work (PoW) systems. Ouroboros divides time into epochs and slots, with slot leaders responsible for creating new blocks and validating transactions within each slot. This approach ensures that the blockchain remains secure and decentralized while enabling high transaction throughput and low latency.

Cardano’s blockchain consists of two main layers: the Cardano Settlement Layer (CSL) and the Cardano Computation Layer (CCL). The CSL serves as the foundation for the platform’s native cryptocurrency, ADA, and facilitates secure and efficient peer-to-peer transactions. It employs a UTXO (Unspent Transaction Output) model similar to Bitcoin, where transactions are represented as inputs and outputs, ensuring transparency and immutability.

On top of the CSL, the CCL enables the execution of smart contracts and decentralized applications (dApps) using Plutus, Cardano’s purpose-built programming language. Plutus is based on Haskell, a functional programming language known for its safety and reliability, and allows developers to write smart contracts with formal verification capabilities, ensuring correctness and security. Additionally, Cardano supports interoperability with other blockchains through sidechains and cross-chain communication protocols, enabling seamless integration with existing infrastructure and networks.

Cardano’s development is guided by a rigorous scientific approach, with ongoing research and peer-reviewed papers driving innovation and advancement. The platform’s roadmap is divided into distinct phases, including Byron (foundation), Shelley (decentralization), Goguen (smart contracts), Basho (scaling), and Voltaire (governance), each focusing on specific features and functionalities. This modular approach allows for continuous improvement and evolution, ensuring that Cardano remains at the forefront of blockchain technology.

Supply of Coins

The supply of coins for Cardano (ADA) is governed by a predetermined protocol established during its initial launch. The total maximum supply of ADA is capped at 45 billion coins. Unlike some cryptocurrencies that have fixed supplies, Cardano’s distribution occurs gradually through a process called “minting.” During the initial phase, ADA tokens were distributed through a public sale and allocated to early supporters, development, and the Cardano treasury. Ongoing minting of ADA occurs through the process of staking, where ADA holders can delegate their coins to stake pools to participate in the network’s consensus and earn rewards. This incentivizes stakeholders to actively participate in the security and governance of the network while also distributing newly minted coins in a decentralized manner. As a result, the circulating supply of ADA gradually increases over time, with new coins being minted and distributed to participants in the Cardano ecosystem.

Historical context and background

Solana, a relatively new entrant in the cryptocurrency arena, emerged against the backdrop of an increasingly crowded and competitive landscape in the digital currency space. Founded in 2020 by Anatoly Yakovenko, a former engineer at Qualcomm, Solana sought to address some of the inherent scalability and speed limitations plaguing earlier blockchain platforms like Ethereum. The platform is named after the Solana Beach in California, where Yakovenko often surfed, symbolizing the project’s ambition to ride the waves of innovation and technological advancement.

Unlike many other cryptocurrencies that primarily rely on Proof of Work (PoW) or Proof of Stake (PoS) consensus mechanisms, Solana introduced a novel consensus mechanism known as Proof of History (PoH). This mechanism aims to optimize transaction processing speed by organizing transactions into a series of chronological events, enabling parallel transaction processing, and significantly enhancing scalability. Solana’s emphasis on scalability and throughput has positioned it as a promising platform for decentralized applications (dApps) and decentralized finance (DeFi) projects seeking high-performance blockchain infrastructure. Its innovative approach has garnered attention and support from investors and developers alike, propelling Solana into the spotlight as one of the leading contenders in the cryptocurrency space.

Doge Coin: Unraveling the Phenomenon of the Internet’s Favourite Cryptocurrency

May 2, 2024April 5, 2024 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2024) explains the evolution of the most popular memecoin, Dogecoin.

Historical context and background

Dogecoin, a cryptocurrency that started as a joke, quickly evolved into a significant player in the world of digital assets. Created in December 2013 by software engineers Billy Markus and Jackson Palmer, Dogecoin was initially intended to satirize the hype surrounding cryptocurrencies at the time. The coin’s logo features the Shiba Inu dog from the “Doge” meme, which was immensely popular on the internet during that period.

Key features

Decentralization

Like most cryptocurrencies, Dogecoin operates on a decentralized network, meaning it is not controlled by any single entity or organization. Transactions are recorded on a public ledger known as the blockchain, which is maintained by a network of nodes.

Scrypt Algorithm

Dogecoin uses the Scrypt algorithm for its proof-of-work consensus mechanism, which is less energy-intensive compared to Bitcoin’s SHA-256 algorithm. This allows for greater accessibility to mining for individuals with standard computer hardware.

Fast Transactions

Dogecoin boasts relatively fast transaction times, with blocks being mined approximately every minute. This makes it suitable for quick and efficient transfers of value.

Low Transaction Fees

Transaction fees on the Dogecoin network are typically minimal, making it cost-effective for transferring even small amounts of value.

Meme Culture

Dogecoin’s branding and marketing heavily leverage internet meme culture, particularly the “Doge” meme featuring the Shiba Inu dog. This playful and approachable branding sets Dogecoin apart from other cryptocurrencies and contributes to its widespread appeal.

Use cases

Tipping

Dogecoin gained popularity early on for its use as a tipping currency on social media platforms like Reddit and Twitter. Users can easily send small amounts of Dogecoin to content creators or other users as a form of appreciation.

Charitable Donations

The Dogecoin community has a history of supporting charitable causes and disaster relief efforts. Dogecoin has been used to raise funds for various initiatives, including sponsoring athletes, funding clean water projects, and aiding during natural disasters.

E-commerce

Some online merchants and retailers accept Dogecoin as a form of payment for goods and services. This includes businesses ranging from small independent shops to larger e-commerce platforms.

Micropayments

Dogecoin’s low transaction fees and fast confirmation times make it suitable for micropayments, allowing users to easily transfer small amounts of value online.

Community Engagement

Dogecoin continues to serve as a vehicle for community engagement and participation. Its lighthearted and inclusive nature fosters a sense of camaraderie among its users, who often come together for events, fundraisers, and online discussions.

Experimental Projects

Developers and enthusiasts sometimes use Dogecoin for experimental projects or to explore new applications of blockchain technology. These projects can range from art and gaming to decentralized finance (DeFi) experiments.

Technology and underlying blockchain

Dogecoin operates on a blockchain-based technology similar to Bitcoin and many other cryptocurrencies. It employs a decentralized peer-to-peer network that relies on nodes spread across the globe to validate and record transactions. Dogecoin’s blockchain uses the Scrypt hashing algorithm, which was initially designed to facilitate quicker confirmation times compared to Bitcoin’s SHA-256 algorithm. This choice of algorithm allows for a more accessible mining process, enabling individuals with standard computer hardware to participate in securing the network and earning rewards. Transactions on the Dogecoin network are grouped into blocks, which are then added to the blockchain through a process known as mining. Miners compete to solve complex mathematical puzzles, and the first miner to solve a puzzle validates the transactions in a block and adds it to the blockchain. Dogecoin’s block time is approximately one minute, resulting in faster transaction confirmations compared to Bitcoin’s ten-minute block time. Additionally, Dogecoin originally had a limitless supply, with a fixed reward of 10,000 DOGE per block; however, this changed in 2014 to an inflationary model, where a fixed number of coins are added to the supply each year. This combination of technology and economic design contributes to Dogecoin’s unique characteristics and its appeal within the cryptocurrency ecosystem.

Supply of coins

Dogecoin’s supply dynamics are distinctive within the cryptocurrency landscape. Initially launched with no hard cap on its total supply, Dogecoin features an inflationary issuance model designed to maintain a steady influx of coins into the market. Unlike Bitcoin’s fixed supply of 21 million coins, Dogecoin’s issuance rate started at 5 billion coins per year and gradually decreases over time. This inflationary nature ensures a continuous supply of Dogecoin, theoretically allowing for ongoing miner rewards and a sustained incentive for network participation. However, it’s worth noting that while the supply of Dogecoin is technically infinite, the rate of new coin creation diminishes over time, resulting in a decreasing inflation rate and a more stable supply trajectory. This unique supply mechanism distinguishes Dogecoin from many other cryptocurrencies and can influence its long-term economic dynamics and utility as a medium of exchange or store of value.

ERC-20 Standard of Ethereum for USD Coin

The ERC-20 standard, short for Ethereum Request for Comment 20, is a widely adopted technical specification governing the creation and implementation of fungible tokens on the Ethereum blockchain. Introduced by Fabian Vogelsteller and Vitalik Buterin in 2015, ERC-20 defines a set of rules and functions that enable seamless interoperability between different tokens, ensuring compatibility with various decentralized applications (DApps) and wallets. Tokens adhering to the ERC-20 standard are characterized by a consistent set of methods, including transfer, balance inquiry, and approval mechanisms, facilitating easy integration and widespread adoption across the Ethereum ecosystem. This standardization has played a pivotal role in the proliferation of tokenization, empowering developers to create diverse tokenized assets, conduct crowdfunding campaigns through Initial Coin Offerings (ICOs), and establish decentralized exchanges (DEXs) where ERC-20 tokens are traded autonomously. Additionally, ERC-20 compliance enhances security and interoperability, fostering trust and usability within the Ethereum network.

Supply of coins

The supply dynamics of USD Coin (USDC) are governed by its underlying smart contract protocol and the management of its issuer, Centre Consortium, a collaboration between Circle and Coinbase. USDC operates on a principle of full backing, where each USDC token issued is backed by an equivalent number of US dollars held in reserve. This backing ensures a 1:1 peg to the US dollar, maintaining its stability. The issuance and redemption of USDC are facilitated through regulated financial institutions that hold the corresponding fiat reserves. Moreover, USDC’s supply is transparently audited on a regular basis, with attestations provided by reputable auditing firms to verify the adequacy of reserves. Through these mechanisms, the supply of USDC remains elastic, expanding or contracting based on market demand while preserving its stability and trustworthiness as a stablecoin in the digital asset ecosystem.

Tokenized Assets: Tether is utilized to represent traditional assets in tokenized form on blockchain platforms, enabling fractional ownership and increased liquidity for real-world assets.

Controversy

While Tether has gained popularity for its stability and utility, it has also faced criticism and regulatory scrutiny, particularly regarding its reserve backing and transparency. The paper “Is Bitcoin Really Untethered?”, analyses Tether’s controversies revealing that the significant growth of Tether, the largest pegged cryptocurrency, may not solely be driven by organic investor demand but also by a scheme to artificially inflate cryptocurrency prices. By analyzing the blockchains of Bitcoin and Tether, the researchers found evidence suggesting that a major player on Bitfinex utilizes Tether to purchase large amounts of Bitcoin during price downturns, effectively supporting Bitcoin prices. This intervention is particularly pronounced near round-number price thresholds, indicating a strategic approach to price support. The data also suggests that Tether issuance correlates with a month-end need for dollar reserves, implying partial reserve backing. Overall, these findings lend support to the hypothesis that Tether’s growth is supply-driven and potentially manipulative.

Furthermore, the paper highlights the broader implications of these findings, suggesting that price manipulation in cryptocurrencies can have significant distortive effects beyond standard supply-and-demand dynamics. It highlights the need for external surveillance, monitoring, and regulatory frameworks in the cryptocurrency space, challenging the notion that innovative technologies alone can bypass the need for traditional oversight. The conclusion suggests that while cryptocurrencies offer new possibilities for financial innovation, they are not immune to the risks associated with dubious activities and speculative bubbles, which could ultimately lead to further price distortions and negative impacts on the market.

Technology and underlying blockchain

Tether (USDT), a the stablecoin, utilizes blockchain technology across various networks to provide a digital asset pegged to traditional fiat currencies. The Ethereum-based ERC-20 version is the most prevalent, benefiting from Ethereum’s widespread adoption and smart contract capabilities, making it a cornerstone for decentralized exchanges and DeFi applications. Tether also operates on the Tron blockchain (TRC-20), offering faster transactions and reduced fees, particularly appealing for high-frequency trading. Acknowledging the demand for scalability and cost-effectiveness, Tether has expanded to alternative blockchains like Binance Smart Chain and Solana. These adaptations highlight Tether’s commitment to meeting diverse market needs. Managed by Tether Limited, the stablecoin asserts stability through regular audits and claims of holding equivalent fiat reserves, although controversies have arisen regarding transparency. The dynamic interplay of Tether across various blockchains underscores its pivotal role in the evolving landscape of digital finance.

Supply of coins

The market supply of Tether (USDT), a leading stablecoin, plays a crucial role in the broader cryptocurrency ecosystem. Tether’s supply dynamics are intrinsically linked to its unique issuance mechanism. Tether Limited, the company behind USDT, mints new tokens by receiving equivalent amounts of fiat currency, primarily the US Dollar, in its reserves. This issuance process is supposed to ensure a 1:1 peg between USDT and the underlying fiat currency, promoting price stability.

The market supply of Tether expands as demand for the stablecoin increases. Traders and investors often turn to USDT as a safe haven during times of high volatility, effectively increasing the circulating supply. This heightened demand results in additional Tether being issued to maintain the peg, thus influencing the overall supply in the market.

Monitoring Tether’s supply is of particular interest due to its significant impact on liquidity within the cryptocurrency space. An influx of USDT into the market provides traders with a reliable means to navigate price fluctuations without fully exiting the crypto market, enhancing liquidity and potentially mitigating market volatility.

XRP: Pioneering Financial Revolution

May 20, 2024March 25, 2024 by Snehasish CHINARA

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2024) explains the cryptocurrency XRP/Ripple.

Historical context and background

XRP, the digital currency associated with the Ripple network, emerged against the backdrop of a growing interest in blockchain technology and its potential applications beyond cryptocurrencies. The development of Ripple began in 2012 when Jed McCaleb, Chris Larsen, and Arthur Britto joined forces to create a decentralized digital currency system. Ripple Labs, the company behind XRP, aimed to address the inefficiencies in traditional cross-border payments by providing a fast and cost-effective alternative. Unlike Bitcoin, which relies on a proof-of-work consensus mechanism, Ripple utilizes a unique consensus algorithm called the Ripple Protocol Consensus Algorithm (RPCA). The XRP Ledger, the underlying technology, is designed to facilitate quick and secure transactions, making it particularly appealing for financial institutions. Over the years, Ripple has garnered both support and criticism within the crypto community due to its centralized nature and ongoing legal challenges. Nevertheless, its focus on facilitating seamless global transactions has positioned XRP as a significant player in the evolving landscape of digital assets.

Key features and use cases

Fast and Low-Cost Transactions: One of the primary features of XRP is its speed and cost-effectiveness. The XRP Ledger is capable of processing transactions in just a few seconds, making it significantly faster than traditional banking systems and some other cryptocurrencies. The low transaction fees associated with XRP contribute to its appeal for cross-border payments.

Liquidity and Scalability: XRP is designed to handle a high volume of transactions, providing liquidity for financial institutions. This scalability is crucial for the adoption of XRP in large-scale financial applications, including remittances and institutional transfers.

Interoperability: Ripple aims to facilitate interoperability between different financial systems. XRP can act as a bridge currency between fiat currencies, enabling seamless and efficient transactions across borders. This interoperability is particularly valuable in the context of global finance.

Decentralization with Unique Consensus Algorithm: While Ripple has faced criticism for some aspects of centralization, the XRP Ledger employs the Ripple Protocol Consensus Algorithm (RPCA) for transaction validation. This consensus mechanism is more energy-efficient compared to proof-of-work used by some other cryptocurrencies.

Partnerships with Financial Institutions: Ripple has formed partnerships with various financial institutions, including banks and payment service providers. The aim is to leverage XRP for real-time, cross-border payments, reducing settlement times and costs for these institutions.

Smart Contracts and Tokenization: Ripple has also explored adding smart contract functionality to the XRP Ledger, expanding its use cases beyond simple transactions. Additionally, the platform has the potential for tokenization of real-world assets, allowing for the representation of various assets on the blockchain.

Stability and Predictable Supply: XRP has a fixed supply of 100 billion tokens, with a portion held by Ripple Labs. This fixed supply aims to provide stability and predictability, which could be attractive for businesses and investors.

While XRP has faced regulatory challenges and debates about its decentralization, its unique features and focus on solving real-world financial issues position it as a cryptocurrency with substantial potential in the global financial landscape.

Technology and underlying blockchain

XRP, the cryptocurrency associated with the Ripple network, operates on a distinct technological framework, utilizing a consensus algorithm that sets it apart from traditional proof-of-work systems. At the heart of XRP’s technology is the XRP Ledger, a decentralized blockchain that enables fast and secure transactions. The unique consensus mechanism employed by Ripple is known as the Ripple Protocol Consensus Algorithm (RPCA). Unlike the energy-intensive mining processes seen in proof-of-work systems, RPCA operates on a consensus model that involves a network of independent validators reaching agreement on the order and validity of transactions. This consensus mechanism allows the XRP Ledger to achieve high throughput and swift confirmation times, making it well-suited for the efficient processing of cross-border payments and financial transactions. Additionally, the XRP Ledger supports the issuance of various tokens, potentially expanding its use cases beyond its native cryptocurrency. Despite debates about the decentralization of Ripple, the technology behind XRP continues to evolve, showcasing a commitment to addressing the challenges and opportunities in the rapidly evolving blockchain and cryptocurrency space. Additionally, the platform has explored the integration of smart contract functionality, opening possibilities for more complex and programmable transactions. The focus on scalability, interoperability, and speed positions XRP as a blockchain solution tailored for the demands of the global financial industry, particularly in the context of cross-border payments and remittances.

Supply of coins

The supply dynamics of XRP, the native cryptocurrency of the Ripple network, play a crucial role in shaping its market characteristics. Unlike Bitcoin, which relies on a mining process to gradually release new coins into circulation, XRP was created with its entire supply generated at inception. XRP has a fixed maximum supply of 100 billion coins, a feature that distinguishes it from some other cryptocurrencies with potentially infinite supplies. Notably, a substantial portion of the XRP supply is held by Ripple Labs, the company behind the cryptocurrency. Approximately 55 billion XRP are held in escrow by Ripple Labs, the company behind the development of the Ripple protocol. This escrow mechanism is designed to release a specific amount of XRP into circulation each month, reducing the potential for market manipulation and ensuring a predictable supply trajectory.

This allocation has been a point of discussion and scrutiny within the crypto community, with debates surrounding the potential impact of such centralization on the coin’s decentralization ethos. Ripple has taken steps to address concerns, implementing strategies such as the escrow system, which locks a large amount of XRP in time-released contracts to be gradually released into circulation. The controlled release aims to provide transparency and mitigate concerns related to sudden market influxes. The fixed supply, along with Ripple’s strategic initiatives, contributes to the stability and predictability of XRP in the market, influencing investor perceptions and shaping the overall market dynamics of the cryptocurrency.

Ethereum – Unleashing Blockchain Innovation

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2024) explains Bitcoin which is considered as the mother of all cryptocurrencies.

Historical context and background

Ethereum is a groundbreaking blockchain platform that emerged in the wake of Bitcoin’s success in 2015. While Bitcoin introduced and popularized the blockchain concept, Ethereum has leveraged this technology more effectively than any other digital currency. Promoters of new projects tend to rely on Ethereum’s tools rather than embark on the lengthy and expensive process of developing a new blockchain. Ethereum was conceived by a young Canadian programmer, Vitalik Buterin, who saw limitations in Bitcoin’s functionality and envisioned a decentralized platform capable of executing smart contracts. Buterin’s idea gained traction in the cryptocurrency community, and he, along with a team of developers, published the Ethereum whitepaper in late 2013. The platform’s official development began in 2014, with a crowdfunding campaign that raised over $18 million in Bitcoin, making it one of the most successful initial coin offerings (ICOs) of its time. Ethereum’s genesis block was mined on July 30, 2015, marking the official launch of the network.

Ethereum’s innovative concept of smart contracts and decentralized applications (DApps) quickly garnered attention within the blockchain and cryptocurrency space. The platform introduced a Turing-complete programming language, enabling developers to create a wide array of decentralized applications. Ethereum’s native cryptocurrency, Ether (ETH), serves as both a digital currency and a utility token within the ecosystem. Over the years, Ethereum has undergone several network upgrades to improve scalability and security, most notably the transition from a proof-of-work (PoW) to a proof-of-stake (PoS) consensus mechanism with the Ethereum 2.0 upgrade. This transition aims to address the network’s scalability issues and reduce its energy consumption, positioning Ethereum as a sustainable and versatile blockchain platform for the future. Today, Ethereum continues to play a pivotal role in the blockchain and decentralized finance (DeFi) space, powering a vast array of projects, including NFT platforms, decentralized exchanges, and decentralized applications that have reshaped the way we think about finance and technology.

Key Features of Ethereum

Smart Contracts

Ethereum is renowned for its pioneering smart contract functionality. Smart contracts are self-executing agreements with predefined rules and conditions, enabling automated and trustless transactions. This feature has broad applications in various industries, including finance, supply chain management, and legal services.

Decentralization

Ethereum operates on a decentralized network of nodes, making it resistant to censorship and single points of failure. This decentralization ensures the security and integrity of the blockchain, with no single entity having control over the network.

Ether (ETH)

Ethereum’s native cryptocurrency, Ether, serves as both a digital currency and a utility token. It’s used to pay for transaction fees, secure the network through staking in Ethereum 2.0, and as a medium of exchange within the ecosystem.

Interoperability

Ethereum is designed to interact with other blockchains and networks, fostering compatibility and collaboration across the blockchain ecosystem. Projects like Polkadot and Cosmos aim to enhance this interoperability.

EVM (Ethereum Virtual Machine)

The Ethereum Virtual Machine is a runtime environment for executing smart contracts. It’s a critical component that ensures the same execution of smart contracts across all Ethereum nodes, making Ethereum’s ecosystem reliable and consistent.

EIPs (Ethereum Improvement Proposals)

Ethereum has a robust governance model for protocol upgrades and improvements, with EIPs serving as the mechanism for proposing and implementing changes. This allows for community-driven innovation and adaptation.

Use Cases of Ethereum

Decentralized Finance (DeFi)

Ethereum is at the heart of the DeFi movement, offering lending, borrowing, trading, and yield farming services through DApps like Compound, Aave, and Uniswap. DeFi has disrupted traditional finance, providing open and inclusive access to financial services.

Non-Fungible Tokens (NFTs)

Ethereum’s ERC-721 and ERC-1155 token standards have fueled the NFT boom. NFTs enable the ownership and trade of unique digital assets, from art and music to virtual real estate and collectibles, all recorded on the blockchain.

Supply Chain Management

Ethereum’s transparent and tamper-proof ledger is used to track and verify the authenticity and provenance of products. This enhances supply chain efficiency and trust, reducing fraud and counterfeiting.

Gaming and Virtual Worlds

Ethereum is the platform of choice for blockchain-based gaming and virtual reality experiences. DApps like Decentraland and Axie Infinity allow users to trade in-game assets and participate in virtual economies.

Tokenization of Assets

Real-world assets, such as real estate, stocks, and commodities, can be tokenized on the Ethereum blockchain, making them more accessible for investment and trading.

Identity Verification

Ethereum can be used to secure and manage digital identities, enhancing privacy and reducing the risk of identity theft.

Social Impact

Ethereum is leveraged for social impact projects, including humanitarian aid distribution, voting systems, and tracking philanthropic donations, ensuring transparency and accountability.

Content Distribution

Ethereum-based projects are exploring decentralized content platforms, enabling creators to have more control over their intellectual property and revenue.

Ethereum’s versatility and ongoing development make it a crucial platform for a wide range of applications, from financial innovation to social change and beyond, driving the evolution of the blockchain and cryptocurrency space.

Technology and underlying blockchain

Ethereum’s underlying technology is rooted in blockchain, a distributed ledger system known for its security, transparency, and decentralization. Ethereum, like Bitcoin, employs a blockchain to record and verify transactions, but it offers a distinct set of features and capabilities that set it apart. At the core of Ethereum’s technology is the Ethereum Virtual Machine (EVM), a decentralized computing environment that executes smart contracts. Smart contracts are self-executing agreements with predefined rules and conditions that automate processes without the need for intermediaries.

Ethereum uses a consensus mechanism known as Proof of Stake (PoS), which is a significant departure from Bitcoin’s Proof of Work (PoW). PoS allows network participants, known as validators, to create new blocks and secure the network by locking up a certain amount of Ether as collateral. This approach is more energy-efficient and scalable compared to PoW, addressing some of the limitations that Bitcoin faces. Ethereum’s blockchain is a public and permissionless network, meaning that anyone can participate, transact, and develop decentralized applications (DApps) on the platform without needing approval.

The Ethereum ecosystem also employs a variety of token standards, with ERC-20 and ERC-721 being the most well-known. ERC-20 tokens are fungible and often used for cryptocurrencies, while ERC-721 tokens are non-fungible and have powered the explosion of NFTs (Non-Fungible Tokens). These standards have facilitated the creation and interoperability of a vast array of digital assets and DApps on the platform. Ethereum’s robust governance model, through Ethereum Improvement Proposals (EIPs), allows the community to suggest and implement changes, ensuring that the platform remains adaptable and responsive to evolving needs and challenges. Ethereum’s groundbreaking technology and active development community have positioned it as a leader in the blockchain space, with far-reaching implications for industries beyond just cryptocurrencies.

Supply of coins

Ethereum initially used a proof-of-work (PoW) consensus algorithm for coin mining, similar to Bitcoin. The process involved miners solving complex mathematical puzzles to validate transactions and add new blocks to the blockchain. Miners competed to solve these puzzles, and the first one to succeed was rewarded with newly minted Ethereum coins (ETH). This process was resource-intensive and required significant computational power.

However, Ethereum has been undergoing a transition to a proof-of-stake (PoS) consensus mechanism as part of its Ethereum 2.0 upgrade. The PoS model doesn’t rely on miners solving computational puzzles but instead relies on validators who lock up a certain amount of cryptocurrency as collateral to propose and validate new blocks. Validators are chosen to create new blocks based on the amount of cryptocurrency they hold and are willing to “stake” as collateral.

This transition to PoS is occurring in multiple phases. The Beacon Chain, which is the PoS blockchain that runs parallel to the existing PoW chain, was launched in December 2020. The full transition to Ethereum 2.0, including the complete shift to PoS, is expected to occur in multiple subsequent phases.

As of Q1 2023, there are approximately 121,826,163.06 Ethereum (ETH) coins in circulation, a key distinction from Bitcoin, which has a capped supply of 21 million. Ethereum, created by Vitalik Buterin, was designed without a specific supply limit, allowing for an unlimited number of coins if mining continues. Despite this, there is a cap of 18 million ETH coins that can be mined annually, equating to around 2 ETH per block. Ethereum Classic (ETC), a separate blockchain resulting from a community dispute, also exists with 135.3 billion coins. The Ethereum blockchain’s size was 175 GB in 2021, considerably smaller than Bitcoin’s 412 GB. Approximately 5750 Ethereum blocks are mined daily, with mining difficulty increasing and around 2,151 active nodes globally, primarily in the USA. Ethereum’s potential to become deflationary is acknowledged, contingent on mining costs exceeding rewards, as stated in a GitHub disclaimer.

Bitcoin: the mother of all cryptocurrencies

In this article, Snehasish CHINARA (ESSEC Business School, Grande Ecole Program – Master in Management, 2022-2024) explains Bitcoin which is considered as the mother of all cryptocurrencies.

Historical context and background

The genesis of Bitcoin can be traced back to the aftermath of the Financial Crisis of 2008, when a growing desire emerged for a currency immune to central authority control. Traditional banks had faltered, leading to the devaluation of money through government-sanctioned printing. The absence of a definitive limit on money creation fostered uncertainty. Bitcoin ingeniously addressed this quandary by establishing a fixed supply of coins and a controlled production rate through transparent coding. This code’s openness ensured that no entity, including governments, could manipulate the currency’s value. Consequently, Bitcoin’s worth became solely determined by market dynamics, evading the arbitrary alterations typical of government-managed currencies.

Furthermore, Bitcoin revolutionized financial transactions by eliminating reliance on third-party intermediaries, exemplified by banks. Users can now engage in direct peer-to-peer transactions, circumventing the potential for intermediaries to engage in risky financial ventures akin to the 2008 Financial Crisis. The process of safeguarding one’s Bitcoins is equally innovative, as users manage their funds through a Bitcoin Wallet. Unlike traditional banks, these wallets operate as personal assets, with users as their own bankers. While various companies offer wallet services, the underlying code remains accessible for review, ensuring customers’ trust and the safety of their deposits.

Key features and use cases

Examples of areas where Bitcoin is currently being used:

Digital Currency: Bitcoin serves as a digital currency for everyday transactions, allowing users to buy goods and services online and in physical stores.
Crypto Banking: Bitcoin is used in decentralized finance (DeFi) applications, where users can lend, borrow, and earn interest on their Bitcoin holdings.
Asset Tokenization: Bitcoin is used to tokenize real-world assets like real estate and art, making them more accessible and divisible among investors.
Onchain Governance: Some blockchain projects utilize Bitcoin for on-chain governance, enabling token holders to vote on protocol upgrades and changes.
Smart Contracts: While Ethereum is more widely associated with smart contracts, Bitcoin’s second layer solutions like RSK (Rootstock) allow for the execution of smart contracts on the Bitcoin blockchain.
Corporate Treasuries: Large corporations, such as Tesla, have invested in Bitcoin as a store of value and an asset to diversify their corporate treasuries.
State Treasuries: Some countries, like El Salvador, have adopted Bitcoin as legal tender and added it to their national treasuries to facilitate cross-border remittances and financial inclusion.
Store of Value During Times of Conflict: In regions with economic instability or conflict, Bitcoin is used as a hedge against currency devaluation and asset confiscation.
Online Gambling: Bitcoin is widely accepted in online gambling platforms, providing users with a secure and pseudonymous way to wager on games and sports.
Salary Payments for Freelancers in Emerging Markets: Freelancers in countries with limited access to traditional banking use Bitcoin to receive payments from international clients, circumventing costly and slow remittance services.
Cross-Border Transactions with Bitcoin Gold: Cross-border transactions can often be complex, time-consuming, and costly due to the involvement of multiple intermediaries and the varying regulations of different countries. However, Bitcoin Gold offers a streamlined solution for facilitating global payments, making cross-border transactions more efficient and accessible.

These examples highlight the diverse utility of Bitcoin, ranging from everyday transactions to more complex financial applications and as a tool for economic empowerment in various contexts.

Technology and underlying blockchain

Blockchain technology is the foundational innovation that underpins Bitcoin, the world’s first and most well-known cryptocurrency. At its core, blockchain is a decentralized and distributed ledger system that records transactions across a network of computers in a secure and transparent manner. In the context of Bitcoin, this blockchain serves as a public ledger that tracks every transaction ever made with the cryptocurrency. What sets blockchain apart is its ability to ensure trust and security without the need for a central authority, such as a bank or government. Each block in the chain contains a set of transactions, and these blocks are linked together in a chronological and immutable fashion. This means that once a transaction is recorded on the blockchain, it cannot be altered or deleted. This transparency, immutability, and decentralization make blockchain technology a revolutionary tool not only for digital currencies like Bitcoin but also for a wide range of applications in various industries, from finance and supply chain management to healthcare and beyond.

Moreover, Bitcoin operates on a decentralized network of computers (nodes) worldwide. These nodes validate and confirm transactions, ensuring that the network remains secure, censorship-resistant, and immune to central control. The absence of a central authority is a fundamental characteristic of Bitcoin and a key differentiator from traditional financial systems. Bitcoin relies on a PoW consensus mechanism for securing its network. Miners compete to solve complex mathematical puzzles, and the first one to solve it gets the right to add a new block of transactions to the blockchain. This process ensures the security of the network, prevents double-spending, and maintains the integrity of the ledger. Bitcoin has a fixed supply of 21 million coins, a feature hard-coded into its protocol. The rate at which new Bitcoins are created is reduced by half approximately every four years through a process known as a “halving.” This limited supply is in stark contrast to fiat currencies, which can be printed without restriction.

These technological aspects collectively make Bitcoin a groundbreaking innovation that has disrupted traditional finance and is increasingly studied and integrated into the field of finance. It offers unique opportunities and challenges for finance students to explore, including its impact on monetary policy, investment, and the broader financial ecosystem.

Supply of coins

Looking at the supply side of bitcoins, the number of bitcoins in circulation is given by the following mathematical formula:

Formula for the number of bitcoins in circulation

This calculation hinges upon the fundamental concept of the Bitcoin supply schedule, which employs a diminishing issuance rate through a process known as “halving”.

Figure 2 represents the evolution of the number of bitcoins in circulation overt time based on the above formula.

Historical data for the Bitcoin market prices

The market price of Bitcoin is a dynamic and intricate element that reflects a multitude of factors, both intrinsic and extrinsic. The gradual rise in market value over time indicates a willingness among investors and traders to offer higher prices for the cryptocurrency. This signifies a rising interest and strong belief in the project’s potential for the future. The market price reflects the collective sentiment of investors and traders. Comparing the market price of Bitcoin to other similar cryptocurrencies or benchmark assets can provide insights into its relative strength and performance within the market.

The value of Bitcoin in the market is influenced by a variety of elements, with each factor contributing uniquely to their pricing. One of the most significant influences is market sentiment and investor psychology. These factors can cause prices to shift based on positive news, regulatory changes, or reactive selling due to fear. Furthermore, the real-world implementations and usages of Bitcoin are crucial for its prosperity. Concrete use cases such as Decentralized Finance (DeFi), Non-Fungible Tokens (NFTs), and international transactions play a vital role in creating demand and propelling price appreciation. Meanwhile, adherence to basic economic principles is evident in the supply-demand dynamics, where scarcity due to limited issuance, halving events, and token burns interact with the balance between supply and demand.

With the number of coins in circulation, the information on the price of coins for a given currency is also important to compute Bitcoin’s market capitalization.

We estimated these two parameters over the period from September 17, 2014 to December 31, 2022. The annualized mean of daily returns is equal to 30.81% and the annualized standard deviation of daily returns is equal to 62.33%.

Figure 9 below represents the Gaussian distribution of the Bitcoin daily returns with parameters estimated over the period from September 17, 2014 to December 31, 2022.

Risk measures of the Bitcoin returns

The R program that you can download above also allows you to compute risk measures about the returns of the Bitcoin.

Table 5 below presents the following risk measures estimated for the Bitcoin:

The long-term volatility (the unconditional standard deviation estimated over the entire period)
The short-term volatility (the standard deviation estimated over the last three months)
The Value at Risk (VaR) for the left tail (the 5% quantile of the historical distribution)
The Value at Risk (VaR) for the right tail (the 95% quantile of the historical distribution)
The Expected Shortfall (ES) for the left tail (the average loss over the 5% quantile of the historical distribution)
The Expected Shortfall (ES) for the right tail (the average loss over the 95% quantile of the historical distribution)
The Stress Value (SV) for the left tail (the 1% quantile of the tail distribution estimated with a Generalized Pareto distribution)
The Stress Value (SV) for the right tail (the 99% quantile of the tail distribution estimated with a Generalized Pareto distribution)

The volatility is a global measure of risk as it considers all the returns. The Value at Risk (VaR), Expected Shortfall (ES) and Stress Value (SV) are local measures of risk as they focus on the tails of the distribution. The study of the left tail is relevant for an investor holding a long position in the Bitcoin while the study of the right tail is relevant for an investor holding a short position in the Bitcoin.
