Sociology, Crisis and Conflict Essay Example | Topics and Well Written Essays - 1750 words
Sociology, Crisis and Conflict - Essay Example The subject matter of this essay states about Sociology, Crises and Conflict, while under this a question arise which state; "Medicine alone cannot rid humanity of the scourge of AIDS." How authentic is this assertion Can AID be curable only through medicine or there are other approaches that need to bring forward to achieve for achieving that purpose In the end of the essay, it would get to understand about these. Meanwhile, at this point, let flash back once again to talk about already raising debate on health and social issues. No doubt, health is a social issue that needs to have great concentrations from government and private organizations in all communities across the globe. As social means the ensuring of well being of the people, thus, health issue most to be included on that aspect. In Barents Euro -Artatic Region for example, health matter is going hand in hand with other social issues. "The new Program on Health and Related Social Issueswill develop the necessary co-operation between social and health institutions in order to enhance the health situation in the Barents Euro-Arctic region. Vulnerable groups in the population should be the main target of the Program, also taking into account the special problems of sparsely populated areas. Three areas of priority have been chosen." (Working Group on Health and Related Social Issues). However, the issue ... Meanwhile, it is observed that it very true that medicine alone cannot cure the suffering, trouble and tension cause by AID. The disease AID is a very serious event resulting in great destruction and change, which is also politicized world wide, especially in the 21 century. How can medicine alone can cure a disease which is widely promoted by International medical authorities, government and non-government organization, including media, given information that frighten and contradict It must not be possible that the medicine alone can do this work. BACKGROUND OF AID DISEASE. It is noted in an article titled (Evidence That HIV Causes AID) that "acquired immunodeficiency syndrome (AIDS) was first recognized in 1981 and has since become a major worldwide pandemic. AIDS is caused by the human immunodeficiency virus (HIV). By leading to the destruction and/or functional impairment of cells of the immune system, notably CD4+ T cells, HIV progressively destroys the body's ability to fight infections and certain cancers. An HIV-infected person is diagnosed with AIDS when his or her immune system is seriously compromised and manifestations of HIV infection are severe. The U.S. Centers for Disease Control and Prevention (CDC) currently defines AIDS in an adult or adolescent age 13 years or older as the presence of one of 26 conditions indicative of severe immunosuppressant associated with HIV infection, such as Pneumocystis carinii pneumonia (PCP), a condition extraordinarily rare in people without HIV infection".The United state for example has begin to witnessing the escalation of the incidence of HIV Disease from 1981, up to the year 2006, which is approximately 25 years back. The situation not only adversely

LEADERSHIP STYLES Essay Example | Topics and Well Written Essays - 750 words
LEADERSHIP STYLES - Essay Example Over the period of time, the nature and orientation of the leadership therefore has changed and increasing body of research is suggesting interesting aspects about leadership. The leadership styles can vary and depend upon the ability of the leader to lead the organization and followers in a particular manner. From the perspective of nursing leadership can be important as it outlines the way as to how one will lead as the career progress takes place over the period of time. It is therefore important for nurses to clearly understand the difference between management and leadership besides understanding different leadership styles. This understanding is critical because it directly have an impact on the performance. This paper will discuss and explore two different leadership styles and how that leadership style or leader fits in my philosophy of leader. A comparison and contrast will also be made between leadership and management. Transformational leadership is considered as the leadership which can bring in positive change within individuals to achieve certain objectives. This type of leadership style is often considered as one the most important ways to actually convert followers into leaders by systematically transforming the way they approach different aspects of the organizational environment or their career. By redesigning the values and belief systems, this approach towards leadership creates strong changes within the followers and therefore makes some important changes in the way they approach different aspects of their life and organization. It is also important to note that a transformational leader is also a moral example for the followers. As such leaders become like role models for improving the moral standing of the followers too. (Roesner, 1990) Another style of leadership is based upon the notion of servant leadership which is based upon the idea of giving preference to

Hume Versus Kant Essay Example for Free
Hume Versus Kant Essay Hume and Kant offered two differing views on morality. Humes philosophy regarding moral theory came from the belief that reason alone can never cause action. Desire or thoughts cause action. Because reason alone can never cause action, morality is rooted in us and our perception of the world and what we want to gain from it. Virtue arises from acting on a desire to help others. Humes moral theory is therefore a virtue-centered morality rather than the natural-law morality, which saw morality as coming from God. Kants notion of morality stems from his notion of one universal moral law. This law is pertinent to all people and can be used at all times before carrying our actions According to Kant, you ought to act according to the maxim that is qualified for universal law giving; that is, you ought to act so that the maxim of your action may become a universal law. While Hume and Kants moral theory differ dramatically, they share one quality and that is the fact that neither centers around the concept of God and his will. Humes theories may be considered by some not really philosophical theories at all. It is to say that he is not searching for that philosophical life that is seen in a Plato, or Augustine. He believes that capitalism promotes prosperity for people, and that only science and math is the realm for reason. To discuss Humes ethical theory you have to look at the central theme, which are feelings. Humes ethical theory says that moral judgments are made on feelings as oppose to reason. Humes feelings are based upon the belief that people make moral judgments because it is useful to society. He uses the examples of benevolence and justice to support this idea. Benevolence leads to happiness in society, which is the main basis for moral approval. Justice, for Hume, is regarded as good because again it is useful to society. He says that justice would not exist if everybody was not selfish, and one of its main uses is to protect private property. Justice for Hume is a very business oriented type of justice in which a transaction that is made must be suitable for both parties. If humans were not selfish than justice would not even come to mind in these types of situations because the transaction would be totally dominated by one individual, and that would not be justice. Humes view poses the question, which is better social peace or economic prosperity? Hume states that human beings are an animal whose life consists of worldly pleasures, and this is what leads them to a happy life. Again we see a clear contradiction to what traditional philosophers believe to be a happy life. As you can see Hume leaves out the spiritual, reasoning, and thinking part of human nature. Leaving all these factors out he comes up with his contributions to the well being of society. He believes that chastity, confidentiality, avoiding gossip, avoiding spying, being well mannered, and loyal are what can lead you to becoming prosperous. Hume looks at this from being prosperous only from a business-orientated point of view. People do like to become prosperous and have economic growth, but is that all that matters to us as humans? For Hume these feelings are justified because he says that we naturally care about other people and if we do not suffer from something we have a natural inclination to help others out. Hume finally comes a conclusion to his ethical theory in which he states that there are only four reasons in which to do morally good: useful to society, useful to oneself, agreeable to oneself, agreeable to others. Actions that are morally good are categorized into one of these four categories. These actions must be made with sentiment or feeling over reason, for Hume states man is a creature with feelings and reason lets us figure that out. Hume believed that reason is, and ought only to be, the slave of the passions. He argued that reason is used to discover the causes of pain or pleasure, but it is the prospect of pain or pleasure that causes action, not the reasoning alone, as that is entirely indifferent to us. This notion of always being motivated by pleasure or pain is very important, as it follows from this that when we act morally, it is a desire that makes us act and not reason. Since morals, therefore, have an influence on the actions and affections, if follows that they cannot be derived from reason, and that because reason alone, as we have already proved, can never have any such influence. Kant takes a different approach in his ethical theory and the understanding of morality and what is morally good. For Kant moral goodness is defined as goodwill, and that we as humans have a moral obligation to do what is right. He says that moral worth is seen much clearer if someone does things out of duty. Opposite of what Hume says Kant believes that feelings and inclinations are irrelevant and that feelings are not what drive moral obligations. Then how does Kant justify what is morally obliged? He has cancelled out feelings, and has left it as an obligation for people. For Kant first you must take out all feelings. Moral obligation must be binding for everyone. If any action cannot be approved be everyone than it is not morally obliged. The standard for moral standards has to be universal or absolute. Kants ethical theory is put into a comparison of categorical and hypothetical imperatives. Hypothetical imperatives are looked upon as recommendations or laws by others. This is to say that it is someone else or some other thing is telling us what to do. Hypothetical imperatives are unproblematic. They are straightforward sentences that express mundane statements of fact. Categorical ones, on the other hand, are highly problematic. Categorical imperatives deal with autonomy. These are the moral obligations that Kant believes in, the morally obliged actions. In Kants view, only if a person is acting solely on the categorical imperative such as doing something out of duty, can the act be morally good. This is because if somebody is acting out of the hypothetical imperative, he/she has an ulterior motive in acting in that way and are therefore not acting out of duty but are pursuing a certain end. They need not be acting in self-interest, but if they act because of a desire to act in that way, this is not morally worthy. You can still act morally if it gives you pleasure, as long as the reason for your action is solely out of duty. For instance we ought to help other because you may need help some day. What makes it valuable is that it is valuable in itself. It allows us to treat ourselves and others with self respect. It is clearly seen that in Kants theory there is no feelings or emotions attached to these theories only obligations that will benefit all of society. When taking into account who is right or wrong, the type of person you are comes into play. Some individuals live their lives based off of feelings and emotions alone, and most decisions that these types of individuals make are what is going to them happy or something that could perhaps make them sad but another group in society happy. Then there are the other groups of individuals that do things without thinking of who they will affect but only take into account what they believe they should do based on societys circumstances. Ultimately the decision on how to make moral judgments should be entirely based on you and your character and your experiences. If a person has been hurt by trying to be morally good then his feelings will come into play no matter how he made his original decision. If this person was making a decision based on obligation and he still got hurt from it in the long run then his next decision could be very feeling based. These two decisions on morality may continue to intertwine with each other. Hume and Kant are similar in that their moral theories are not the will as laid down by God, instead they see morality as embedded in humans themselves. However from here the theories diverge. Hume sees moral judgements as being caused by sentiments of pain or pleasure within an agent as reason alone can never motivate, whereas Kant see the only moral actions as being those caused by reason alone, or the categorical imperative. Both theories have difficulty with coming up with absolute moral laws Humes theory because absolute morality would appear to be impossible if morality is based on an individuals sentiment, and Kants theory because it cannot prove the existence of the categorical imperative.
Credit Risk Dissertation
Credit Risk Dissertation CREDIT RISK EXECUTIVE SUMMARY The future of banking will undoubtedly rest on risk management dynamics. Only those banks that have efficient risk management system will survive in the market in the long run. The major cause of serious banking problems over the years continues to be directly related to lax credit standards for borrowers and counterparties, poor portfolio risk management, or a lack of attention to deterioration in the credit standing of a banks counterparties. Credit risk is the oldest and biggest risk that bank, by virtue of its very nature of business, inherits. This has however, acquired a greater significance in the recent past for various reasons. There have been many traditional approaches to measure credit risk like logit, linear probability model but with passage of time new approaches have been developed like the Credit+, KMV Model. Basel I Accord was introduced in 1988 to have a framework for regulatory capital for banks but the ââ¬Å"one size fit allâ⬠approach led to a shift, to a new and comprehensive approach -Basel II which adopts a three pillar approach to risk management. Banks use a number of techniques to mitigate the credit risks to which they are exposed. RBI has prescribed adoption of comprehensive approach for the purpose of CRM which allows fuller offset of security of collateral against exposures by effectively reducing the exposure amount by the value ascribed to the collateral. In this study, a leading nationalized bank is taken to study the steps taken by the bank to implement the Basel- II Accord and the entire framework developed for credit risk management. The bank under the study uses the credit scoring method to evaluate the credit risk involved in various loans/advances. The bank has set up special software to evaluate each case under various parameters and a monitoring system to continuously track each assets performance in accordance with the evaluation parameters. CHAPTER 1 INTRODUCTION 1.1 Rationale Credit Risk Management in todays deregulated market is a big challenge. Increased market volatility has brought with it the need for smart analysis and specialized applications in managing credit risk. A well defined policy framework is needed to help the operating staff identify the risk-event, assign a probability to each, quantify the likely loss, assess the acceptability of the exposure, price the risk and monitor them right to the point where they are paid off. Generally, Banks in India evaluate a proposal through the traditional tools of project financing, computing maximum permissible limits, assessing management capabilities and prescribing a ceiling for an industry exposure. As banks move in to a new high powered world of financial operations and trading, with new risks, the need is felt for more sophisticated and versatile instruments for risk assessment, monitoring and controlling risk exposures. It is, therefore, time that banks managements equip them fully to grapple with the demands of creating tools and systems capable of assessing, monitoring and controlling risk exposures in a more scientific manner. According to an estimate, Credit Risk takes about 70% and 30% remaining is shared between the other two primary risks, namely Market risk (change in the market price and operational risk i.e., failure of internal controls, etc.). Quality borrowers (Tier-I borrowers) were able to access the capital market directly without going through the debt route. Hence, the credit route is now more open to lesser mortals (Tier-II borrowers). With margin levels going down, banks are unable to absorb the level of loan losses. Even in banks which regularly fine-tune credit policies and streamline credit processes, it is a real challenge for credit risk managers to correctly identify pockets of risk concentration, quantify extent of risk carried, identify opportunities for diversification and balance the risk-return trade-off in their credit portfolio. The management of banks should strive to embrace the notion of ââ¬Ëuncertainty and risk in their balance sheet and instill the need for approaching credit administration from a ââ¬Ërisk-perspective across the system by placing well drafted strategies in the hands of the operating staff with due material support for its successful implementation. There is a need for Strategic approach to Credit Risk Management (CRM) in Indian Commercial Banks, particularly in view of; (1) Higher NPAs level in comparison with global benchmark (2) RBI s stipulation about dividend distribution by the banks (3) Revised NPAs level and CAR norms (4) New Basel Capital Accord (Basel -II) revolution 1.2 OBJECTIVES To understand the conceptual framework for credit risk. To understand credit risk under the Basel II Accord. To analyze the credit risk management practices in a Leading Nationalised Bank 1.3 RESEARCH METHODOLOGY Research Design: In order to have more comprehensive definition of the problem and to become familiar with the problems, an extensive literature survey was done to collect secondary data for the location of the various variables, probably contemporary issues and the clarity of concepts. Data Collection Techniques: The data collection technique used is interviewing. Data has been collected from both primary and secondary sources. Primary Data: is collected by making personal visits to the bank. Secondary Data: The details have been collected from research papers, working papers, white papers published by various agencies like ICRA, FICCI, IBA etc; articles from the internet and various journals. 1.4 LITERATURE REVIEW * Merton (1974) has applied options pricing model as a technology to evaluate the credit risk of enterprise, it has been drawn a lot of attention from western academic and business circles.Mertons Model is the theoretical foundation of structural models. Mertons model is not only based on a strict and comprehensive theory but also used market information stock price as an important variance toevaluate the credit risk.This makes credit risk to be a real-time monitored at a much higher frequency.This advantage has made it widely applied by the academic and business circle for a long time. Other Structural Models try to refine the original Merton Framework by removing one or more of unrealistic assumptions. * Black and Cox (1976) postulate that defaults occur as soon as firms asset value falls below a certain threshold. In contrast to the Merton approach, default can occur at any time. The paper by Black and Cox (1976) is the first of the so-called First Passage Models (FPM). First passage models specify default as the first time the firms asset value hits a lower barrier, allowing default to take place at any time. When the default barrier is exogenously fixed, as in Black and Cox (1976) and Longstaff and Schwartz (1995), it acts as a safety covenant to protect bondholders. Black and Cox introduce the possibility of more complex capital structures, with subordinated debt. * Geske (1977) introduces interest-paying debt to the Merton model. * Vasicek (1984) introduces the distinction between short and long term liabilities which now represents a distinctive feature of the KMV model. Under these models, all the relevant credit risk elements, including default and recovery at default, are a function of the structural characteristics of the firm: asset levels, asset volatility (business risk) and leverage (financial risk). * Kim, Ramaswamy and Sundaresan (1993) have suggested an alternative approach which still adopts the original Merton framework as far as the default process is concerned but, at the same time, removes one of the unrealistic assumptions of the Merton model; namely, that default can occur only at maturity of the debt when the firms assets are no longer sufficient to cover debt obligations. Instead, it is assumed that default may occur anytime between the issuance and maturity of the debt and that default is triggered when the value of the firms assets reaches a lower threshold level. In this model, the RR in the event of default is exogenous and independent from the firms asset value. It is generally defined as a fixed ratio of the outstanding debt value and is therefore independent from the PD. The attempt to overcome the shortcomings of structural-form models gave rise to reduced-form models. Unlike structural-form models, reduced-form models do not condition default on the value of the firm, and parameters related to the firms value need not be estimated to implement them. * Jarrow and Turnbull (1995) assumed that, at default, a bond would have a market value equal to an exogenously specified fraction of an otherwise equivalent default-free bond. * Duffie and Singleton (1999) followed with a model that, when market value at default (i.e. RR) is exogenously specified, allows for closed-form solutions for the term-structure of credit spreads. * Zhou (2001) attempt to combine the advantages of structural-form models a clear economic mechanism behind the default process, and the ones of reduced- form models unpredictability of default. This model links RRs to the firm value at default so that the variation in RRs is endogenously generated and the correlation between RRs and credit ratings reported first in Altman (1989) and Gupton, Gates and Carty (2000) is justified. Lately portfolio view on credit losses has emerged by recognising that changes in credit quality tend to comove over the business cycle and that one can diversify part of the credit risk by a clever composition of the loan portfolio across regions, industries and countries. Thus in order to assess the credit risk of a loan portfolio, a bank must not only investigate the creditworthiness of its customers, but also identify the concentration risks and possible comovements of risk factors in the portfolio. * CreditMetrics by Gupton et al (1997) was publicized in 1997 by JP Morgan. Its methodology is based on probability of moving from one credit quality to another within a given time horizon (credit migration analysis). The estimation of the portfolio Value-at-Risk due to Credit (Credit-VaR) through CreditMetrics A rating system with probabilities of migrating from one credit quality to another over a given time horizon (transition matrix) is the key component of the credit-VaR proposed by JP Morgan. The specified credit risk horizon is usually one year. A rating system with probabilities of migrating from one credit quality to another over a given time horizon (transition matrix) is the key component of the credit-VaR proposed by JP Morgan. The specified credit risk horizon is usually one year. * (Sy, 2007), states that the primary cause of credit default is loan delinquency due to insufficient liquidity or cash flow to service debt obligations. In the case of unsecured loans, we assume delinquency is a necessary and sufficient condition. In the case of collateralized loans, delinquency is a necessary, but not sufficient condition, because the borrower may be able to refinance the loan from positive equity or net assets to prevent default. In general, for secured loans, both delinquency and insolvency are assumed necessary and sufficient for credit default. CHAPTER 2 THEORECTICAL FRAMEWORK 2.1 CREDIT RISK: Credit risk is risk due to uncertainty in a counterpartys (also called an obligors or credits) ability to meet its obligations. Because there are many types of counterpartiesââ¬âfrom individuals to sovereign governmentsââ¬âand many different types of obligationsââ¬âfrom auto loans to derivatives transactionsââ¬âcredit risk takes many forms. Institutions manage it in different ways. Although credit losses naturally fluctuate over time and with economic conditions, there is (ceteris paribus) a statistically measured, long-run average loss level. The losses can be divided into two categories i.e. expected losses (EL) and unexpected losses (UL). EL is based on three parameters: à ·Ã¢â ¬Ã The likelihood that default will take place over a specified time horizon (probability of default or PD) à · â⠬à The amount owned by the counterparty at the moment of default (exposure at default or EAD) à ·Ã¢â ¬Ã The fraction of the exposure, net of any recoveries, which will be lost following a default event (loss given default or LGD). EL = PD x EAD x LGD EL can be aggregated at various different levels (e.g. individual loan or entire credit portfolio), although it is typically calculated at the transaction level; it is normally mentioned either as an absolute amount or as a percentage of transaction size. It is also both customer- and facility-specific, since two different loans to the same customer can have a very different EL due to differences in EAD and/or LGD. It is important to note that EL (or, for that matter, credit quality) does not by itself constitute risk; if losses always equaled their expected levels, then there would be no uncertainty. Instead, EL should be viewed as an anticipated ââ¬Å"cost of doing businessâ⬠and should therefore be incorporated in loan pricing and ex ante provisioning. Credit risk, in fact, arises from variations in the actual loss levels, which give rise to the so-called unexpected loss (UL). Statistically speaking, UL is simply the standard deviation of EL. UL= ÃÆ' (EL) = ÃÆ' (PD*EAD*LGD) Once the bank- level credit loss distribution is constructed, credit economic capital is simply determined by the banks tolerance for credit risk, i.e. the bank needs to decide how much capital it wants to hold in order to avoid insolvency because of unexpected credit losses over the next year. A safer bank must have sufficient capital to withstand losses that are larger and rarer, i.e. they extend further out in the loss distribution tail. In practice, therefore, the choice of confidence interval in the loss distribution corresponds to the banks target credit rating (and related default probability) for its own debt. As Figure below shows, economic capital is the difference between EL and the selected confidence interval at the tail of the loss distribution; it is equal to a multiple K (often referred to as the capital multiplier) of the standard deviation of EL (i.e. UL). The shape of the loss distribution can vary considerably depending on product type and borrower credit quality. For example, high quality (low PD) borrowers tend to have proportionally less EL per unit of capital charged, meaning that K is higher and the shape of their loss distribution is more skewed (and vice versa). Credit risk may be in the following forms: * In case of the direct lending * In case of the guarantees and the letter of the credit * In case of the treasury operations * In case of the securities trading businesses * In case of the cross border exposure 2.2 The need for Credit Risk Rating: The need for Credit Risk Rating has arisen due to the following: 1. With dismantling of State control, deregulation, globalisation and allowing things to shape on the basis of market conditions, Indian Industry and Indian Banking face new risks and challenges. Competition results in the survival of the fittest. It is therefore necessary to identify these risks, measure them, monitor and control them. 2. It provides a basis for Credit Risk Pricing i.e. fixation of rate of interest on lending to different borrowers based on their credit risk rating thereby balancing Risk Reward for the Bank. 3. The Basel Accord and consequent Reserve Bank of India guidelines requires that the level of capital required to be maintained by the Bank will be in proportion to the risk of the loan in Banks Books for measurement of which proper Credit Risk Rating system is necessary. 4. The credit risk rating can be a Risk Management tool for prospecting fresh borrowers in addition to monitoring the weaker parameters and taking remedial action. The types of Risks Captured in the Banks Credit Risk Rating Model The Credit Risk Rating Model provides a framework to evaluate the risk emanating from following main risk categorizes/risk areas: * Industry risk * Business risk * Financial risk * Management risk * Facility risk * Project risk 2.3 WHY CREDIT RISK MEASUREMENT? In recent years, a revolution is brewing in risk as it is both managed and measured. There are seven reasons as to why certain surge in interest: 1. Structural increase in bankruptcies: Although the most recent recession hit at different time in different countries, most statistics show a significant increase in bankruptcies, compared to prior recession. To the extent that there has been a permanent or structural increase in bankruptcies worldwide- due to increase in the global competition- accurate credit analysis become even more important today than in past. 2. Disintermediation: As capital markets have expanded and become accessible to small and mid sized firms, the firms or borrowers ââ¬Å"left behindâ⬠to raise funds from banks and other traditional financial institutions (FIs) are likely to be smaller and to have weaker credit ratings. Capital market growth has produced ââ¬Å"a winnersâ⬠curse effect on the portfolios of traditional FIs. 3. More Competitive Margins: Almost paradoxically, despite the decline in the average quality of loans, interest margins or spreads, especially in wholesale loan markets have become very thin. In short, the risk-return trade off from lending has gotten worse. A number of reasons can be cited, but an important factor has been the enhanced competition for low quality borrowers especially from finance companies, much of whose lending activity has been concentrated at the higher risk/lower quality end of the market. 4. Declining and Volatile Values of Collateral: Concurrent with the recent Asian and Russian debt crisis in well developed countries such as Switzerland and Japan have shown that property and real assets value are very hard to predict, and to realize through liquidation. The weaker (and more uncertain) collateral values are, the riskier the lending is likely to be. Indeed the current concerns about deflation worldwide have been accentuated the concerns about the value of real assets such as property and other physical assets. 5. The Growth Of Off- Balance Sheet Derivatives: In many of the very large U.S. banks, the notional value of the off-balance-sheet exposure to instruments such as over-the-counter (OTC) swaps and forwards is more than 10 times the size of their loan books. Indeed the growth in credit risk off the balance sheet was one of the main reasons for the introduction, by the Bank for International Settlements (BIS), of risk based capital requirements in 1993. Under the BIS system, the banks have to hold a capital requirement based on the mark- to- market current values of each OTC Derivative contract plus an add on for potential future exposure. 6. Technology Advances in computer systems and related advances in information technology have given banks and FIs the opportunity to test high powered modeling techniques. A survey conducted by International Swaps and Derivatives Association and the Institute of International Finance in 2000 found that survey participants (consisting of 25 commercial banks from 10 countries, with varying size and specialties) used commercial and internal databases to assess the credit risk on rated and unrated commercial, retail and mortgage loans. 7. The BIS Risk-Based Capital Requirements Despite the importance of above six reasons, probably the greatest incentive for banks to develop new credit risk models has been dissatisfaction with the BIS and central banks post-1992 imposition of capital requirements on loans. The current BIS approach has been described as a ââ¬Ëone size fits all policy, irrespective of the size of loan, its maturity, and most importantly, the credit quality of the borrowing party. Much of the current interest in fine tuning credit risk measurement models has been fueled by the proposed BIS New Capital Accord (or so Called BIS II) which would more closely link capital charges to the credit risk exposure to retail, commercial, sovereign and interbank credits. Chapter- 3 Credit Risk Approaches and Pricing 3.1 CREDIT RISK MEASUREMENT APPROACHES: 1. CREDIT SCORING MODELS Credit Scoring Models use data on observed borrower characteristics to calculate the probability of default or to sort borrowers into different default risk classes. By selecting and combining different economic and financial borrower characteristics, a bank manager may be able to numerically establish which factors are important in explaining default risk, evaluate the relative degree or importance of these factors, improve the pricing of default risk, be better able to screen out bad loan applicants and be in a better position to calculate any reserve needed to meet expected future loan losses. To employ credit scoring model in this manner, the manager must identify objective economic and financial measures of risk for any particular class of borrower. For consumer debt, the objective characteristics in a credit -scoring model might include income, assets, age occupation and location. For corporate debt, financial ratios such as debt-equity ratio are usually key factors. After data are identified, a statistical technique quantifies or scores the default risk probability or default risk classification. Credit scoring models include three broad types: (1) linear probability models, (2) logit model and (3) linear discriminant model. LINEAR PROBABILITY MODEL: The linear probability model uses past data, such as accounting ratios, as inputs into a model to explain repayment experience on old loans. The relative importance of the factors used in explaining the past repayment performance then forecasts repayment probabilities on new loans; that is can be used for assessing the probability of repayment. Briefly we divide old loans (i) into two observational groups; those that defaulted (Zi = 1) and those that did not default (Zi = 0). Then we relate these observations by linear regression to s set of j casual variables (Xij) that reflects quantative information about the ith borrower, such as leverage or earnings. We estimate the model by linear regression of: Zi = à £Ã ²jXij + error Where à ²j is the estimated importance of the jth variable in explaining past repayment experience. If we then take these estimated à ²js and multiply them by the observed Xij for a prospective borrower, we can derive an expected value of Zi for the probability of repayment on the loan. LOGIT MODEL: The objective of the typical credit or loan review model is to replicate judgments made by loan officers, credit managers or bank examiners. If an accurate model could be developed, then it could be used as a tool for reviewing and classifying future credit risks. Chesser (1974) developed a model to predict noncompliance with the customers original loan arrangement, where non-compliance is defined to include not only default but any workout that may have been arranged resulting in a settlement of the loan less favorable to the tender than the original agreement. Chessers model, which was based on a technique called logit analysis, consisted of the following six variables. X1 = (Cash + Marketable Securities)/Total Assets X2 = Net Sales/(Cash + Marketable Securities) X3 = EBIT/Total Assets X4 = Total Debt/Total Assets X5 = Total Assets/ Net Worth X6 = Working Capital/Net Sales The estimated coefficients, including an intercept term, are Y = -2.0434 -5.24X1 + 0.0053X2 6.6507X3 + 4.4009X4 0.0791X5 0.1020X6 Chessers classification rule for above equation is If P> 50, assign to the non compliance group and If PâⰠ¤50, assign to the compliance group. LINEAR DISCRIMINANT MODEL: While linear probability and logit models project a value foe the expected probability of default if a loan is made, discriminant models divide borrowers into high or default risk classes contingent on their observed characteristic (X). Altmans Z-score model is an application of multivariate Discriminant analysis in credit risk modeling. Financial ratios measuring probability, liquidity and solvency appeared to have significant discriminating power to separate the firm that fails to service its debt from the firms that do not. These ratios are weighted to produce a measure (credit risk score) that can be used as a metric to differentiate the bad firms from the set of good ones. Discriminant analysis is a multivariate statistical technique that analyzes a set of variables in order to differentiate two or more groups by minimizing the within-group variance and maximizing the between group variance simultaneously. Variables taken were: X1::Working Capital/ Total Asset X2: Retained Earning/ Total Asset X3: Earning before interest and taxes/ Total Asset X4: Market value of equity/ Book value of total Liabilities X5: Sales/Total Asset The original Z-score model was revised and modified several times in order to find the scoring model more specific to a particular class of firm. These resulted in the private firms Z-score model, non manufacturers Z-score model and Emerging Market Scoring (EMS) model. 3.2 New Approaches TERM STRUCTURE DERIVATION OF CREDIT RISK: One market based method of assessing credit risk exposure and default probabilities is to analyze the risk premium inherent in the current structure of yields on corporate debt or loans to similar risk-rated borrowers. Rating agencies categorize corporate bond issuers into at least seven major classes according to perceived credit quality. The first four ratings AAA, AA, A and BBB indicate investment quality borrowers. MORTALITY RATE APPROACH: Rather than extracting expected default rates from the current term structure of interest rates, the FI manager may analyze the historic or past default experience the mortality rates, of bonds and loans of a similar quality. Here p1is the probability of a grade B bond surviving the first year of its issue; thus 1 p1 is the marginal mortality rate, or the probability of the bond or loan dying or defaulting in the first year while p2 is the probability of the loan surviving in the second year and that it has not defaulted in the first year, 1-p2 is the marginal mortality rate for the second year. Thus, for each grade of corporate buyer quality, a marginal mortality rate (MMR) curve can show the historical default rate in any specific quality class in each year after issue. RAROC MODELS: Based on a banks risk-bearing capacity and its risk strategy, it is thus necessary ââ¬â bearing in mind the banks strategic orientation ââ¬â to find a method for the efficient allocation of capital to the banks individual siness areas, i.e. to define indicators that are suitable for balancing risk and return in a sensible manner. Indicators fulfilling this requirement are often referred to as risk adjusted performance measures (RAPM). RARORAC (risk adjusted return on risk adjusted capital, usually abbreviated as the most commonly found forms are RORAC (return on risk adjusted capital), Net income is taken to mean income minus refinancing cost, operating cost, and expected losses. It should now be the banks goal to maximize a RAPM indicator for the bank as a whole, e.g. RORAC, taking into account the correlation between individual transactions. Certain constraints such as volume restrictions due to a potential lack of liquidity and the maintenance of solvency based on economic and regulatory capital have to be observed in reaching this goal. From an organizational point of view, value and risk management should therefore be linked as closely as possible at all organizational levels. OPTION MODELS OF DEFAULT RISK (kmv model): KMV Corporation has developed a credit risk model that uses information on the stock prices and the capital structure of the firm to estimate its default probability. The starting point of the model is the proposition that a firm will default only if its asset value falls below a certain level, which is function of its liability. It estimates the asset value of the firm and its asset volatility from the market value of equity and the debt structure in the option theoretic framework. The resultant probability is called Expected default Frequency (EDF). In summary, EDF is calculated in the following three steps: i) Estimation of asset value and volatility from the equity value and volatility of equity return. ii) Calculation of distance from default iii) Calculation of expected default frequency Credit METRICS: It provides a method for estimating the distribution of the value of the assets n a portfolio subject to change in the credit quality of individual borrower. A portfolio consists of different stand-alone assets, defined by a stream of future cash flows. Each asset has a distribution over the possible range of future rating class. Starting from its initial rating, an asset may end up in ay one of the possible rating categories. Each rating category has a different credit spread, which will be used to discount the future cash flows. Moreover, the assets are correlated among themselves depending on the industry they belong to. It is assumed that the asset returns are normally distributed and change in the asset returns causes the change in the rating category in future. Finally, the simulation technique is used to estimate the value distribution of the assets. A number of scenario are generated from a multivariate normal distribution, which is defined by the appropriate credit spread, t he future value of asset is estimated. CREDIT Risk+: CreditRisk+, introduced by Credit Suisse Financial Products (CSFP), is a model of default risk. Each asset has only two possible end-of-period states: default and non-default. In the event of default, the lender recovers a fixed proportion of the total expense. The default rate is considered as a continuous random variable. It does not try to estimate default correlation directly. Here, the default correlation is assumed to be determined by a set of risk factors. Conditional on these risk factors, default of each obligator follows a Bernoulli distribution. To get unconditional probability generating function for the number of defaults, it assumes that the risk factors are independently gamma distributed random variables. The final step in Creditrisk+ is to obtain the probability generating function for losses. Conditional on the number of default events, the losses are entirely determined by the exposure and recovery rate. Thus, the distribution of asset can be estimated from the fol lowing input data: i) Exposure of individual asset ii) Expected default rate iii) Default ate volatilities iv) Recovery rate given default 3.3 CREDIT PRICING Pricing of the credit is essential for the survival of enterprises relying on credit assets, because the benefits derived from extending credit should surpass the cost. With the introduction of capital adequacy norms, the credit risk is linked to the capital-minimum 8% capital adequacy. Consequently, higher capital is required to be deployed if more credit risks are underwritten. The decision (a) whether to maximize the returns on possible credit assets with the existing capital or (b) raise more capital to do more business invariably depends upon p Credit Risk Dissertation Credit Risk Dissertation CREDIT RISK EXECUTIVE SUMMARY The future of banking will undoubtedly rest on risk management dynamics. Only those banks that have efficient risk management system will survive in the market in the long run. The major cause of serious banking problems over the years continues to be directly related to lax credit standards for borrowers and counterparties, poor portfolio risk management, or a lack of attention to deterioration in the credit standing of a banks counterparties. Credit risk is the oldest and biggest risk that bank, by virtue of its very nature of business, inherits. This has however, acquired a greater significance in the recent past for various reasons. There have been many traditional approaches to measure credit risk like logit, linear probability model but with passage of time new approaches have been developed like the Credit+, KMV Model. Basel I Accord was introduced in 1988 to have a framework for regulatory capital for banks but the ââ¬Å"one size fit allâ⬠approach led to a shift, to a new and comprehensive approach -Basel II which adopts a three pillar approach to risk management. Banks use a number of techniques to mitigate the credit risks to which they are exposed. RBI has prescribed adoption of comprehensive approach for the purpose of CRM which allows fuller offset of security of collateral against exposures by effectively reducing the exposure amount by the value ascribed to the collateral. In this study, a leading nationalized bank is taken to study the steps taken by the bank to implement the Basel- II Accord and the entire framework developed for credit risk management. The bank under the study uses the credit scoring method to evaluate the credit risk involved in various loans/advances. The bank has set up special software to evaluate each case under various parameters and a monitoring system to continuously track each assets performance in accordance with the evaluation parameters. CHAPTER 1 INTRODUCTION 1.1 Rationale Credit Risk Management in todays deregulated market is a big challenge. Increased market volatility has brought with it the need for smart analysis and specialized applications in managing credit risk. A well defined policy framework is needed to help the operating staff identify the risk-event, assign a probability to each, quantify the likely loss, assess the acceptability of the exposure, price the risk and monitor them right to the point where they are paid off. Generally, Banks in India evaluate a proposal through the traditional tools of project financing, computing maximum permissible limits, assessing management capabilities and prescribing a ceiling for an industry exposure. As banks move in to a new high powered world of financial operations and trading, with new risks, the need is felt for more sophisticated and versatile instruments for risk assessment, monitoring and controlling risk exposures. It is, therefore, time that banks managements equip them fully to grapple with the demands of creating tools and systems capable of assessing, monitoring and controlling risk exposures in a more scientific manner. According to an estimate, Credit Risk takes about 70% and 30% remaining is shared between the other two primary risks, namely Market risk (change in the market price and operational risk i.e., failure of internal controls, etc.). Quality borrowers (Tier-I borrowers) were able to access the capital market directly without going through the debt route. Hence, the credit route is now more open to lesser mortals (Tier-II borrowers). With margin levels going down, banks are unable to absorb the level of loan losses. Even in banks which regularly fine-tune credit policies and streamline credit processes, it is a real challenge for credit risk managers to correctly identify pockets of risk concentration, quantify extent of risk carried, identify opportunities for diversification and balance the risk-return trade-off in their credit portfolio. The management of banks should strive to embrace the notion of ââ¬Ëuncertainty and risk in their balance sheet and instill the need for approaching credit administration from a ââ¬Ërisk-perspective across the system by placing well drafted strategies in the hands of the operating staff with due material support for its successful implementation. There is a need for Strategic approach to Credit Risk Management (CRM) in Indian Commercial Banks, particularly in view of; (1) Higher NPAs level in comparison with global benchmark (2) RBI s stipulation about dividend distribution by the banks (3) Revised NPAs level and CAR norms (4) New Basel Capital Accord (Basel -II) revolution 1.2 OBJECTIVES To understand the conceptual framework for credit risk. To understand credit risk under the Basel II Accord. To analyze the credit risk management practices in a Leading Nationalised Bank 1.3 RESEARCH METHODOLOGY Research Design: In order to have more comprehensive definition of the problem and to become familiar with the problems, an extensive literature survey was done to collect secondary data for the location of the various variables, probably contemporary issues and the clarity of concepts. Data Collection Techniques: The data collection technique used is interviewing. Data has been collected from both primary and secondary sources. Primary Data: is collected by making personal visits to the bank. Secondary Data: The details have been collected from research papers, working papers, white papers published by various agencies like ICRA, FICCI, IBA etc; articles from the internet and various journals. 1.4 LITERATURE REVIEW * Merton (1974) has applied options pricing model as a technology to evaluate the credit risk of enterprise, it has been drawn a lot of attention from western academic and business circles.Mertons Model is the theoretical foundation of structural models. Mertons model is not only based on a strict and comprehensive theory but also used market information stock price as an important variance toevaluate the credit risk.This makes credit risk to be a real-time monitored at a much higher frequency.This advantage has made it widely applied by the academic and business circle for a long time. Other Structural Models try to refine the original Merton Framework by removing one or more of unrealistic assumptions. * Black and Cox (1976) postulate that defaults occur as soon as firms asset value falls below a certain threshold. In contrast to the Merton approach, default can occur at any time. The paper by Black and Cox (1976) is the first of the so-called First Passage Models (FPM). First passage models specify default as the first time the firms asset value hits a lower barrier, allowing default to take place at any time. When the default barrier is exogenously fixed, as in Black and Cox (1976) and Longstaff and Schwartz (1995), it acts as a safety covenant to protect bondholders. Black and Cox introduce the possibility of more complex capital structures, with subordinated debt. * Geske (1977) introduces interest-paying debt to the Merton model. * Vasicek (1984) introduces the distinction between short and long term liabilities which now represents a distinctive feature of the KMV model. Under these models, all the relevant credit risk elements, including default and recovery at default, are a function of the structural characteristics of the firm: asset levels, asset volatility (business risk) and leverage (financial risk). * Kim, Ramaswamy and Sundaresan (1993) have suggested an alternative approach which still adopts the original Merton framework as far as the default process is concerned but, at the same time, removes one of the unrealistic assumptions of the Merton model; namely, that default can occur only at maturity of the debt when the firms assets are no longer sufficient to cover debt obligations. Instead, it is assumed that default may occur anytime between the issuance and maturity of the debt and that default is triggered when the value of the firms assets reaches a lower threshold level. In this model, the RR in the event of default is exogenous and independent from the firms asset value. It is generally defined as a fixed ratio of the outstanding debt value and is therefore independent from the PD. The attempt to overcome the shortcomings of structural-form models gave rise to reduced-form models. Unlike structural-form models, reduced-form models do not condition default on the value of the firm, and parameters related to the firms value need not be estimated to implement them. * Jarrow and Turnbull (1995) assumed that, at default, a bond would have a market value equal to an exogenously specified fraction of an otherwise equivalent default-free bond. * Duffie and Singleton (1999) followed with a model that, when market value at default (i.e. RR) is exogenously specified, allows for closed-form solutions for the term-structure of credit spreads. * Zhou (2001) attempt to combine the advantages of structural-form models a clear economic mechanism behind the default process, and the ones of reduced- form models unpredictability of default. This model links RRs to the firm value at default so that the variation in RRs is endogenously generated and the correlation between RRs and credit ratings reported first in Altman (1989) and Gupton, Gates and Carty (2000) is justified. Lately portfolio view on credit losses has emerged by recognising that changes in credit quality tend to comove over the business cycle and that one can diversify part of the credit risk by a clever composition of the loan portfolio across regions, industries and countries. Thus in order to assess the credit risk of a loan portfolio, a bank must not only investigate the creditworthiness of its customers, but also identify the concentration risks and possible comovements of risk factors in the portfolio. * CreditMetrics by Gupton et al (1997) was publicized in 1997 by JP Morgan. Its methodology is based on probability of moving from one credit quality to another within a given time horizon (credit migration analysis). The estimation of the portfolio Value-at-Risk due to Credit (Credit-VaR) through CreditMetrics A rating system with probabilities of migrating from one credit quality to another over a given time horizon (transition matrix) is the key component of the credit-VaR proposed by JP Morgan. The specified credit risk horizon is usually one year. A rating system with probabilities of migrating from one credit quality to another over a given time horizon (transition matrix) is the key component of the credit-VaR proposed by JP Morgan. The specified credit risk horizon is usually one year. * (Sy, 2007), states that the primary cause of credit default is loan delinquency due to insufficient liquidity or cash flow to service debt obligations. In the case of unsecured loans, we assume delinquency is a necessary and sufficient condition. In the case of collateralized loans, delinquency is a necessary, but not sufficient condition, because the borrower may be able to refinance the loan from positive equity or net assets to prevent default. In general, for secured loans, both delinquency and insolvency are assumed necessary and sufficient for credit default. CHAPTER 2 THEORECTICAL FRAMEWORK 2.1 CREDIT RISK: Credit risk is risk due to uncertainty in a counterpartys (also called an obligors or credits) ability to meet its obligations. Because there are many types of counterpartiesââ¬âfrom individuals to sovereign governmentsââ¬âand many different types of obligationsââ¬âfrom auto loans to derivatives transactionsââ¬âcredit risk takes many forms. Institutions manage it in different ways. Although credit losses naturally fluctuate over time and with economic conditions, there is (ceteris paribus) a statistically measured, long-run average loss level. The losses can be divided into two categories i.e. expected losses (EL) and unexpected losses (UL). EL is based on three parameters: à ·Ã¢â ¬Ã The likelihood that default will take place over a specified time horizon (probability of default or PD) à · â⠬à The amount owned by the counterparty at the moment of default (exposure at default or EAD) à ·Ã¢â ¬Ã The fraction of the exposure, net of any recoveries, which will be lost following a default event (loss given default or LGD). EL = PD x EAD x LGD EL can be aggregated at various different levels (e.g. individual loan or entire credit portfolio), although it is typically calculated at the transaction level; it is normally mentioned either as an absolute amount or as a percentage of transaction size. It is also both customer- and facility-specific, since two different loans to the same customer can have a very different EL due to differences in EAD and/or LGD. It is important to note that EL (or, for that matter, credit quality) does not by itself constitute risk; if losses always equaled their expected levels, then there would be no uncertainty. Instead, EL should be viewed as an anticipated ââ¬Å"cost of doing businessâ⬠and should therefore be incorporated in loan pricing and ex ante provisioning. Credit risk, in fact, arises from variations in the actual loss levels, which give rise to the so-called unexpected loss (UL). Statistically speaking, UL is simply the standard deviation of EL. UL= ÃÆ' (EL) = ÃÆ' (PD*EAD*LGD) Once the bank- level credit loss distribution is constructed, credit economic capital is simply determined by the banks tolerance for credit risk, i.e. the bank needs to decide how much capital it wants to hold in order to avoid insolvency because of unexpected credit losses over the next year. A safer bank must have sufficient capital to withstand losses that are larger and rarer, i.e. they extend further out in the loss distribution tail. In practice, therefore, the choice of confidence interval in the loss distribution corresponds to the banks target credit rating (and related default probability) for its own debt. As Figure below shows, economic capital is the difference between EL and the selected confidence interval at the tail of the loss distribution; it is equal to a multiple K (often referred to as the capital multiplier) of the standard deviation of EL (i.e. UL). The shape of the loss distribution can vary considerably depending on product type and borrower credit quality. For example, high quality (low PD) borrowers tend to have proportionally less EL per unit of capital charged, meaning that K is higher and the shape of their loss distribution is more skewed (and vice versa). Credit risk may be in the following forms: * In case of the direct lending * In case of the guarantees and the letter of the credit * In case of the treasury operations * In case of the securities trading businesses * In case of the cross border exposure 2.2 The need for Credit Risk Rating: The need for Credit Risk Rating has arisen due to the following: 1. With dismantling of State control, deregulation, globalisation and allowing things to shape on the basis of market conditions, Indian Industry and Indian Banking face new risks and challenges. Competition results in the survival of the fittest. It is therefore necessary to identify these risks, measure them, monitor and control them. 2. It provides a basis for Credit Risk Pricing i.e. fixation of rate of interest on lending to different borrowers based on their credit risk rating thereby balancing Risk Reward for the Bank. 3. The Basel Accord and consequent Reserve Bank of India guidelines requires that the level of capital required to be maintained by the Bank will be in proportion to the risk of the loan in Banks Books for measurement of which proper Credit Risk Rating system is necessary. 4. The credit risk rating can be a Risk Management tool for prospecting fresh borrowers in addition to monitoring the weaker parameters and taking remedial action. The types of Risks Captured in the Banks Credit Risk Rating Model The Credit Risk Rating Model provides a framework to evaluate the risk emanating from following main risk categorizes/risk areas: * Industry risk * Business risk * Financial risk * Management risk * Facility risk * Project risk 2.3 WHY CREDIT RISK MEASUREMENT? In recent years, a revolution is brewing in risk as it is both managed and measured. There are seven reasons as to why certain surge in interest: 1. Structural increase in bankruptcies: Although the most recent recession hit at different time in different countries, most statistics show a significant increase in bankruptcies, compared to prior recession. To the extent that there has been a permanent or structural increase in bankruptcies worldwide- due to increase in the global competition- accurate credit analysis become even more important today than in past. 2. Disintermediation: As capital markets have expanded and become accessible to small and mid sized firms, the firms or borrowers ââ¬Å"left behindâ⬠to raise funds from banks and other traditional financial institutions (FIs) are likely to be smaller and to have weaker credit ratings. Capital market growth has produced ââ¬Å"a winnersâ⬠curse effect on the portfolios of traditional FIs. 3. More Competitive Margins: Almost paradoxically, despite the decline in the average quality of loans, interest margins or spreads, especially in wholesale loan markets have become very thin. In short, the risk-return trade off from lending has gotten worse. A number of reasons can be cited, but an important factor has been the enhanced competition for low quality borrowers especially from finance companies, much of whose lending activity has been concentrated at the higher risk/lower quality end of the market. 4. Declining and Volatile Values of Collateral: Concurrent with the recent Asian and Russian debt crisis in well developed countries such as Switzerland and Japan have shown that property and real assets value are very hard to predict, and to realize through liquidation. The weaker (and more uncertain) collateral values are, the riskier the lending is likely to be. Indeed the current concerns about deflation worldwide have been accentuated the concerns about the value of real assets such as property and other physical assets. 5. The Growth Of Off- Balance Sheet Derivatives: In many of the very large U.S. banks, the notional value of the off-balance-sheet exposure to instruments such as over-the-counter (OTC) swaps and forwards is more than 10 times the size of their loan books. Indeed the growth in credit risk off the balance sheet was one of the main reasons for the introduction, by the Bank for International Settlements (BIS), of risk based capital requirements in 1993. Under the BIS system, the banks have to hold a capital requirement based on the mark- to- market current values of each OTC Derivative contract plus an add on for potential future exposure. 6. Technology Advances in computer systems and related advances in information technology have given banks and FIs the opportunity to test high powered modeling techniques. A survey conducted by International Swaps and Derivatives Association and the Institute of International Finance in 2000 found that survey participants (consisting of 25 commercial banks from 10 countries, with varying size and specialties) used commercial and internal databases to assess the credit risk on rated and unrated commercial, retail and mortgage loans. 7. The BIS Risk-Based Capital Requirements Despite the importance of above six reasons, probably the greatest incentive for banks to develop new credit risk models has been dissatisfaction with the BIS and central banks post-1992 imposition of capital requirements on loans. The current BIS approach has been described as a ââ¬Ëone size fits all policy, irrespective of the size of loan, its maturity, and most importantly, the credit quality of the borrowing party. Much of the current interest in fine tuning credit risk measurement models has been fueled by the proposed BIS New Capital Accord (or so Called BIS II) which would more closely link capital charges to the credit risk exposure to retail, commercial, sovereign and interbank credits. Chapter- 3 Credit Risk Approaches and Pricing 3.1 CREDIT RISK MEASUREMENT APPROACHES: 1. CREDIT SCORING MODELS Credit Scoring Models use data on observed borrower characteristics to calculate the probability of default or to sort borrowers into different default risk classes. By selecting and combining different economic and financial borrower characteristics, a bank manager may be able to numerically establish which factors are important in explaining default risk, evaluate the relative degree or importance of these factors, improve the pricing of default risk, be better able to screen out bad loan applicants and be in a better position to calculate any reserve needed to meet expected future loan losses. To employ credit scoring model in this manner, the manager must identify objective economic and financial measures of risk for any particular class of borrower. For consumer debt, the objective characteristics in a credit -scoring model might include income, assets, age occupation and location. For corporate debt, financial ratios such as debt-equity ratio are usually key factors. After data are identified, a statistical technique quantifies or scores the default risk probability or default risk classification. Credit scoring models include three broad types: (1) linear probability models, (2) logit model and (3) linear discriminant model. LINEAR PROBABILITY MODEL: The linear probability model uses past data, such as accounting ratios, as inputs into a model to explain repayment experience on old loans. The relative importance of the factors used in explaining the past repayment performance then forecasts repayment probabilities on new loans; that is can be used for assessing the probability of repayment. Briefly we divide old loans (i) into two observational groups; those that defaulted (Zi = 1) and those that did not default (Zi = 0). Then we relate these observations by linear regression to s set of j casual variables (Xij) that reflects quantative information about the ith borrower, such as leverage or earnings. We estimate the model by linear regression of: Zi = à £Ã ²jXij + error Where à ²j is the estimated importance of the jth variable in explaining past repayment experience. If we then take these estimated à ²js and multiply them by the observed Xij for a prospective borrower, we can derive an expected value of Zi for the probability of repayment on the loan. LOGIT MODEL: The objective of the typical credit or loan review model is to replicate judgments made by loan officers, credit managers or bank examiners. If an accurate model could be developed, then it could be used as a tool for reviewing and classifying future credit risks. Chesser (1974) developed a model to predict noncompliance with the customers original loan arrangement, where non-compliance is defined to include not only default but any workout that may have been arranged resulting in a settlement of the loan less favorable to the tender than the original agreement. Chessers model, which was based on a technique called logit analysis, consisted of the following six variables. X1 = (Cash + Marketable Securities)/Total Assets X2 = Net Sales/(Cash + Marketable Securities) X3 = EBIT/Total Assets X4 = Total Debt/Total Assets X5 = Total Assets/ Net Worth X6 = Working Capital/Net Sales The estimated coefficients, including an intercept term, are Y = -2.0434 -5.24X1 + 0.0053X2 6.6507X3 + 4.4009X4 0.0791X5 0.1020X6 Chessers classification rule for above equation is If P> 50, assign to the non compliance group and If PâⰠ¤50, assign to the compliance group. LINEAR DISCRIMINANT MODEL: While linear probability and logit models project a value foe the expected probability of default if a loan is made, discriminant models divide borrowers into high or default risk classes contingent on their observed characteristic (X). Altmans Z-score model is an application of multivariate Discriminant analysis in credit risk modeling. Financial ratios measuring probability, liquidity and solvency appeared to have significant discriminating power to separate the firm that fails to service its debt from the firms that do not. These ratios are weighted to produce a measure (credit risk score) that can be used as a metric to differentiate the bad firms from the set of good ones. Discriminant analysis is a multivariate statistical technique that analyzes a set of variables in order to differentiate two or more groups by minimizing the within-group variance and maximizing the between group variance simultaneously. Variables taken were: X1::Working Capital/ Total Asset X2: Retained Earning/ Total Asset X3: Earning before interest and taxes/ Total Asset X4: Market value of equity/ Book value of total Liabilities X5: Sales/Total Asset The original Z-score model was revised and modified several times in order to find the scoring model more specific to a particular class of firm. These resulted in the private firms Z-score model, non manufacturers Z-score model and Emerging Market Scoring (EMS) model. 3.2 New Approaches TERM STRUCTURE DERIVATION OF CREDIT RISK: One market based method of assessing credit risk exposure and default probabilities is to analyze the risk premium inherent in the current structure of yields on corporate debt or loans to similar risk-rated borrowers. Rating agencies categorize corporate bond issuers into at least seven major classes according to perceived credit quality. The first four ratings AAA, AA, A and BBB indicate investment quality borrowers. MORTALITY RATE APPROACH: Rather than extracting expected default rates from the current term structure of interest rates, the FI manager may analyze the historic or past default experience the mortality rates, of bonds and loans of a similar quality. Here p1is the probability of a grade B bond surviving the first year of its issue; thus 1 p1 is the marginal mortality rate, or the probability of the bond or loan dying or defaulting in the first year while p2 is the probability of the loan surviving in the second year and that it has not defaulted in the first year, 1-p2 is the marginal mortality rate for the second year. Thus, for each grade of corporate buyer quality, a marginal mortality rate (MMR) curve can show the historical default rate in any specific quality class in each year after issue.

Pardon Debate :: essays research papers
Pardon Debate à à à à à Does money increase power over the rest of the nation? President Clintonââ¬â¢s last minute pardons before leaving the White House has left a lingering shadow over his two year Presidency. To understand this controversy, we would need to discuss the Mar Rich pardon, the Glenn Braswell pardon, and the negative impact that these had on the former President and former first lady. à à à à à The article ââ¬Å"A President and a pardon, a price?â⬠written by Mark Mezzetti and Gary Cohen, stated that Marc Rich fled from the U.S. to Switzerland in 1983 to dodge a tax fraud charge. On the morning of Clintonââ¬â¢s final day in office, the criticism was becoming well known around the White House. President Clinton had pardoned her from the tax fraud charge. Carol Elder Bruce, the clients lawyer, informed committee staff members that Mrs. Rich had contributed over $200 million to the Clinton Library Fund. (26). A well known source told U.S. News Today that so far Marc Rich has contributed $450,000 in the past three years. (26). Mr. Rich had donated more than $1 million for Democrats between 1991-1992. He also gave $70,000 to Hillary Clintonââ¬â¢s campaign for New Yorkââ¬â¢s Senator. à à à à à While Micheal Milken, former Junk-bond king, waited for a pardon, Clinton fundraisers approached him for money. His spokesman stated that Mr. Milken gave nothing to the fund raiser.(26). But on Presidents Clintonââ¬â¢s last day in office an e-mail had been sent to Jack Quinn by Denis Rich, Marcââ¬â¢s ex-wife, that there was news that Milken will not get the pardon.

Emirates Airline: Penetrating the North American Market
Emirates Airline is known for going against conventional thinking when running its business. Thus far, this strategy has been profitable for the company. In November 2001, the airline announced that it would begin a 13 ? non-stop flight from Dubai to New York starting in June of 2003. However a postponement in the delivery of the Airbus A380-800 aircraft that would service the new route has caused a delay. This will be Emiratesââ¬â¢ attempt at penetrating the North American market. In the current politically charged climate there is debate as to whether or not it will be profitable to expand service to this new route from Dubai to New York. Tensions between Washington and the Arab world create restraints as to when Emirates will be able to expand service. However, the main question currently facing Emirates is whether it should expand to New York at this point in time. Unlike many other airlines, Emirates sees no threat surrounding the tensions in the Middle East. The climate has been this politically charged for the past ten years. In fact, during the first Gulf War in 1991, Emirates Airlines was the only airline that did not cancel any of its flights. They continued flying to Kuwait when a majority of its competitors stopped. Emirates continued business as usual and picked up additional business from those airlines that downsized and stopped flights in the region. This strategy exemplifies how Emirates has gone against conventional thinking and come out ahead. Country Risk Analysis Middle East Region Overview The Middle Eastern region is characterized by economies that are over-dependent on oil; however, they differ on size, wealth, and political agendas. A few of the key players in this region include: Iran, Iraq, United Arab Emirates, Qatar, and Saudi Arabia. Of these countries, the United Arab Emirates is quite comparable in many aspects to its neighbors. The UAE and Qatar are not expected to suffer from as much government instability in the threat of war as the other countries. Iran and Iraq, however, have had their share of political unrest, which has drastically affected their oil exports and prices. To counterattack these effects, Iraq has put pressure on the other OPEC countries to increase oil prices and decrease oil exports to the US and Great Britain. As a result, the GDP of all Middle Eastern countries will decrease due to the heavy reliance of oil revenues in exports and as a percentage of GDP. While oil is what makes these countries wealthy, the UAE, Saudi Arabia, and Qatar enjoy higher GDP per capita over Iraq because of their political situations. Dictatorial governments in Iraq allocate funds to programs that will not necessarily aid the country in the long-run. Literacy rates of Saudi Arabia, Qatar, Iran, and the UAE have increased steadily over the past decade. This is mostly owed to government beliefs that educated citizens will 3 augment the status of the country in all aspects. All five countries export to and import from similar countries including; Japan, Italy, China and the US. The main export for these countries is oil and the main imports are machinery and equipment, chemicals and food. United Arab Emirates The United Arab Emirates (UAE) is located in the Middle East between Oman and Saudi Arabia, bordering the Gulf of Oman and the Persian Gulf. The country is slightly smaller than the state of Maine, which makes it a very small country within the Middle East region. The population of the UAE is approximately 3,480,000 people. The literacy rate for the UAE is 79. 2% for the total population above 15 years. When categorized by sex, men and women have comparable literacy rates, a rarity in the Middle East region. The population is predominantly Muslim (96%), with the remaining 4% of the population consists of Christians, Hindus and others. Although Arabic is the official language of the country, Persian, English, Hindi and Urdu are also spoken. The UAE is a federation state formed on December 2, 1971 and is composed of seven emirates. The emirates included in the UAE are Abu Dhabi, Dubai, Ajman, Fujairah, Sharjah, Ras AlKhaimah, and Umm Al-Qaiwain. Prior to the formation of the federation state, the UAE existed as the Trucial States that belonged to the British for the previous 150 years. The Rulers and the British signed a Perpetual Treaty of Maritime Truce in the 1850s that guarantees peace and protection from external threats. In exchange, the British had direct involvement in its foreign affairs and external defenses. When the British intended to withdraw from the Gulf in 1968, the rulers of the seven emirates came together and formed the federation state with hopes to increase their role in global politics. Economic Environment United Arab Emiratesââ¬â¢ economy is heavily dependent on oil production. Abu Dhabi is the largest producer, followed by Dubai, and to a much lesser extent, the remaining emirates. Although oilââ¬â¢s contribution to GDP has been declining in the past few years, government revenue and the non-oil economy continue to be heavily reliant. GDP for the year ending 2001 was 67. 6(US$bn) and 21,000(US$bn) per capita, and 70% of government revenue resulted from oil production. Fluctuations in oil prices impact the growth and volatility of the UAEââ¬â¢s economy. The UAE is a member of the WTO, but has been slow to comply with its requirements for liberalizing trade and competition. The banking sector is closed to foreign investment and other ventures must be 51% owned by a local partner. The exceptions to these rules are in free zones, where 100% foreign ownership is permitted. The limitations on foreign direct investment deter the process of economic diversification. Abu Dhabi is the most resistant to opening its economy, but it has pursued private sector involvement to improve infrastructure regarding water and power. Dubai has chosen to focus its efforts on expanding its services sector by creating Dubai Internet City (DIC) and Dubai Media City (DMC), which are free zones where investors can retain 100% ownership. Dubai also allows foreign investors to own property and purchase shares in UAE listed companies. The UAE typically runs a budget deficit, and the 2002 budget projects one of Dh2. 17bn. Federal spending is expected to increase by 2. 2%, and revenue is expected to grow by 3%. Abu Dhabi, Dubai and the UAE Central Bank are the main contributors to the federal budget.
