Foundation and Empire 25. Death Of A Psychologist

DuPont A speculation examination DuPont makes an assortment of high-esteem items for industry today, including polymers, synthetic concoctions, filaments, and oil products...products for horticulture, hardware, transportation, clothing, food, aviation, development, and medicinal services. DuPont serves clients in these and different ventures each day, offering better things for better living as the organization gets ready to start its third century of logical, innovative, business, and social accomplishment. DuPont is an examination and innovation based compound and vitality organization with its yearly income surpassing $39 billion. Eleuth?re Ir?n?e du Pont de Nemours, a French migrant, set up DuPont in 1802 of every a little Delaware town. E.I. du Pont was an understudy of Antoine Lavoisier, the father of present day science, and when he came to America he brought some of the new thoughts regarding the assembling of reliably solid explosive. His item touched off at the point when it should, in a way reliable with desires. This was incredibly increased in value by the residents of the developing country, including Thomas Jefferson, who composed expressing gratitude toward du Pont for the nature of his powder, which was being utilized to clear the land at Monticello. Numerous different saints of early America owed their prosperity, and their lives, to the reliable nature of DuPont's first item. This speaks to a decent, solid beginning for an organization. DuPont, which is traveling through the most recent decade of the twentieth century and toward its third century, underlines a few things; contending internationally; honing its business center; expanding efficiency; focusing on security, wellbeing, and natural greatness; and proceeding to expand its huge science and innovative accomplishment. One of DuPont's significant systems is to concentrate on organizations in which DuPont has center capabilities, where DuPont can assemble upper hand. The most outstanding case of this center was the 1993 exchange wherein DuPont procured ICI's nylon business and ICI gained DuPont's acrylics business. This reinforced the organization's position in the worldwide nylon business while stripping a business that no longer fit its portfolio. Another central point in the change of the organization in the1990s was the concentrate on lessening costs and improving profitability. This was important to give the organization the adaptability for serious estimating and to develop piece of the overall industry and income. DuPont had solid plants in a few nations around the globe for some a long time, also, their globalization pattern proceeded during the 1990s. New plants opened in Spain, Singapore, Korea, Taiwan, and China, and a significant specialized help place opened in Japan. In 1994, a Conoco joint endeavor started creating oil from the Ardalin Field in the Russian Arctic- - the principal significant oil field brought into creation by a Russian/Western association since end of the Soviet Union. A further significant advancement was the reclamation of 156 million DuPont shares from Seagram for $8.8 billion in real money and warrants - one of the biggest stock reclamations ever. This huge square of offers was recovered at a 13 percent rebate to showcase cost. While DuPont later sold some new offers, there are 18 percent less shares as of now extraordinary than only before the recovery. This came about in a critical open door for riches creation for our investors. The offer reclamation was made conceivable by four years of cost decrease, profitability improvement furthermore, hierarchical change that have made DuPont solid monetarily and permitted them to move unequivocally and rapidly. The DuPont that rose up out of the organization's change during the 1990s has frequently been portrayed by individuals inside and outside the organization as the new DuPont. This portrayal is just mostly proper, in light of the fact that while DuPont has changed, there are numerous things that continue as before. The center competency in science and innovation, the duty to security, the worry for individuals, the sentiment of network, the accentuation on close to home and corporate respectability, the future center, and in reality the ability to change. DuPont is an organization out for their own advantage, yet in addition generally advantageous enthusiasm of the world. What has consistently set DuPont separated is the nature of the individuals, individuals submitted to making life simpler and better for everyone, pleased to be a piece of an undertaking making better things for better living. That was valid in 1802. Also, it is similarly as genuine today. In the second quarter of 1995 DuPont announced profit for each portion of $1.70, up 47 percent from the $1.16 earned in the second quarter 1994. Total compensation totaled $938 million, contrasted with $792 million earned in 1994. Both profit per share what's more, net salary expanded 27 percent.These exceptional outcomes keep on reflecting solid income gains and progressing efficiency upgrades, said DuPont Chairman Edgar S.Woolard Jr. Deals for the subsequent quarter were $11.1 billion, up 9 percent from earlier year. The second from last quarter of the 1995 business year drove DuPont to a $1.38 per share winning. This number surpassed the $.95 earned in the second from last quarter of 1994 by more than 45%. Total compensation totaled $769 million contrasted with $647 million earned in 1994. Deals for the second from last quarter were

How Can We Help Our Ecosystem - Free Essay Example

When going shopping at the grocery store, do you usually pay attention to where the produce is shipped from? Most of the time, people really do not care about where their food is from. Corporate farms produce many products that people buy everyday, but at a cost. The fact is, everyday the global warming and pollution on the planet gets worse. Although corporate farms supply a majority of the produce, they also produce a majority of the pollution. Buying local is better than buying from corporate farms because it is helping keep the ecosystem clean by producing less pollution, contributing less greenhouse gases, and by having less waste to dispose of. Small, local farms produce less pollution and are more eco friendly than corporate farms. Many harmful chemical products are used in agriculture, the most common being pesticides. When looking at the vast series of environmental problems, it was found that factory farms are one of the top causes of pollution. (Pollution (Water, Air Chemicals))Large scale farming, found at corporate farms, usually use more pesticides in their crop fields. Insecticides, herbicides and fungicides are some of the pesticides used, and although they might be harmless in smaller portions, large farms have to use huge amounts to cover all the crops they grow. The problem is that most of these pesticides contain carcinogens, a substance that can cause cancer in living tissue. Smaller farms, on the other hand, are more environmentally sustainable and more aware about what they use for their plants when farming. Chemical pollution is just one type of pollution that larger farms cause. Water and air pollution ar e also a big factor in factory farms environments, which can lead to a whole other problem, greenhouse gases. Greenhouse gases are becoming a big problem that play a large part in pollution. Factory farms are a danger to the climate as it is a fact that livestock production contributes 14.5 percent of human caused greenhouse emissions. (yes_magazine) Since the factory farms have so much meat that they produce, it is not hard to see just how much greenhouse emissions are caused by them. More sustainable meat production tactics like local farms and grass-fed operations have less greenhouse emissions compared to corporate farms. (yes_magazine) The burning of fossil fuels causes a release of greenhouse gases, such as methane and carbon dioxide, which leads to global warming. Factory farms rely heavily on fossil fuels to help power machinery that is used in their daily routine when tending to their crops and livestock. Also a large majority of fossil fuels is use just to transport the produce, traveling across states to deliver their product. Family farms use less fossil-fuel energy than their co mpetitors as they do not use machines as much in their daily setting. Also, when people buy local, small farms do not have to worry about burning mass amounts of fossil fuels transporting their produce. Some argue that buying locally has some negative effects, and although they are right, there are also a large amount of positive outcomes as well. Buying locally might not be the best plan financially, as most smaller farms have to increase their product cost to beat the competitors, but it is worth it to keep the planet cleaner. Also buying local does have less choices when it comes to picking out products. Some coastal states will not be able to grow certain crops well, and the more central states will not have access to sealand. This can be difficult if you have a specific taste or need. Although there are some negatives when it come to buying local, the benefits outweigh those risks. Local farms are a much greener option, that can help the planet survive. The farms produce less greenhouse gases, and chose not to use harmful pesticides that can have negative effects. Small farms also produce less waste, helping to decrease how much pollution is created. When it comes to manure, larger farms usually produce larger amounts opposed to smaller farms. The problem arises when all the excess nitrogen in the manure evaporates as ammonia. The high levels of ammonia can be harmful and cause burning in the nose and throat. (Beyond Factory Farming) Small, sustainable farms help minimizing waste, the use of chemical, pollution, and other harmful factors to the environment. (Lunsford, 2017) The United States is scored at one of the top in the world of methane emissions from waste. (GRACE Communications Foundation) Data has shown that agriculture is a cause of making 145,000 miles of rivers and streams too polluted for various activities and wildlife. (Corporate Agribusiness) Larger farms usually care more about producing then the effect they have on the ecosystem. With some much livestock, larger farms produce too much manure, more than can be absorbed by other fields. This leads to runoff into water and contaminates it, creating water pollution. Factory farms livestock waste has up to 30 times more power to pollute water than human waste. (Beyond Factory Farming) Raising livestock in smaller amounts can minimize manure as a pollution threat. Buying locally can improve the state of the planet and minimize all negative effects that pollution, greenhouse gases, and livestock waste create. Although there are sacrifices when buying local, such as less seasonal produce and higher prices, the world will become healthier, extending new possibilities for a greener life.

Education in the Computer Science Field 2019

The options for education and the number of degrees available are as varied as the computer industry itself. There are degrees available at every major college and university today; there are many choices in online education as well. Students with some electronics or engineering background may find the continuing education options online to be a convenient option. Students who are beginning their post-secondary education pursuits have choices online as well, and a remarkable number options at traditional universities. For purposes of illustration, well explore a single schools curriculum. One large public university offers bachelors degrees in computer science that focus on subdivided areas. Computer science degrees are offered through the schools department of engineering. One degree is in electrical and computer engineering. Each student must select one of four options as an area of specialty: those are electronics; communications networks and systems; computer systems; and general course of study. The electronics option explores integrated circuits, their manufacture and design and other macro and micro areas of electronics. The networking major is self explanatory. Computer systems is about the design of computers, operating, database and programming systems. General Studies allows the student who is uncertain about a career choice to obtain an overview with some study in each area of the engineering aspects. .u00f5cc9a4ad6a769dae8eb3a2b68256b { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -moz-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -o-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); text-decoration:none; } .u00f5cc9a4ad6a769dae8eb3a2b68256b:active, .u00f5cc9a4ad6a769dae8eb3a2b68256b:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .u00f5cc9a4ad6a769dae8eb3a2b68256b { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .u00f5cc9a4ad6a769dae8eb3a2b68256b .ctaText { font-weight:bold; color:inherit; text-decoration:none; font-size: 16px; } .u00f5cc9a4ad6a769dae8eb3a2b68256b .post Title { color:#000000; text-decoration: underline!important; font-size: 16px; } .u00f5cc9a4ad6a769dae8eb3a2b68256b:hover .postTitle { text-decoration: underline!important; } READ A Quick Lesson On Object-Oriented ProgrammingThere is a bachelors degree in computer science for students interested in all areas of the field.

Water Pollution And Its Effects On Society Essay - 1472 Words

About thirty percent of the world is land mass—the other seventy percent is water. Water is essential to life and all forms of nature need water to thrive in the world. Whether we use the ocean, rivers, lakes, streams, or even the water that comes from your sink, water is a key component to the survival of all living things. Today, chemicals from various places and trash of sorts are getting into the water that are commonly used for drinking and other uses such as fishing, swimming, etc. Contaminated water is affecting the citizens of America in ways that could create long-lasting problems. We can come up with solutions like chemical regulations for companies with leakage, water cleaning devices and how they can be cheaper, and educating the people about hazardous water that will help keep the water safe and clean. Water pollution is a worldwide issue that multiple countries face. In America, the population continues to rise, which means more resources are being used and the e nvironment is changing dramatically due to human impact. Water is one of the resources that are being heavily impacted in some form or fashion. For instance, pollution from man-made products like gasoline, road salts, fertilizers, chemicals, etc. seep into the soil and enters the water that is beneath the earth.

Practitioner Perspectives Importance of Play in Early Years

Question: Discuss about the Practitioner Perspectives on the Importance of play in Early Years Setting? Answer: Introduction: This report shall identify how the early year practitioners can help and support learning through fun and play and shall also analyse the importance of this approach as a whole. The important and significant areas of the discussion shall be learning with the help of role play, and the children have to be supported with the additional significant needs (Jarvis, 2007). Early education with high quality and childcare helps in the childrens development and also provides a strong base for their success in future at school and also in the later life (Allingham, 2003). The childcare and early year practitioners play a very important role in helping the childrens from the birth to the age where they reaches the school with the full potential, which can be done by encouraging the development. For making the early years and the provisions of the child care more accessible, many of the initiatives are to be taken by the government and for this to happen there is always an increased demand of the trained and the qualified practitioners, who can provide the better and the high quality services to the childrens. Senior and learned Psychologists believes that childrens are to learn from experiences which are given by their parents and other adults to shape up them and help them mould themselves in a very good atmosphere (Kellar-Guenther et al., 2013). The learned Practitioners are also required for explaining the behaviour boundaries to the young childrens for them so as to encourage the sense of self control and also enabling them to learn and to think about ones nature and behaviour. A very wide and high range of the provisions of the childcare is noticed within some early years. Childrens who are aged between three and four or even a bit elder are likely to attend all kinds of formal childcare providers like the nurseries, and other schools of kindergartens and playgroups. Research Report: The research finding report explains the design, context, plus the conduct of all kinds of inquiry into the practitioners dealings and the Early Years of the Foundation Stage experiences (Langstaff, 2007). The study has broadly posed basically three broad of questions which lies in the overarching of the theme to describe the practitioners findings of the EYFS: What are the factors by which EYFS influence the daily practice with the childrens and also with their families? How has EYFS made arrangements for the improvements in care as well as the education which the practitioners offered? What obstacles or difficulties do the practitioners come across in effectively using the EYFS?. This study basically focuses and also aims of main two areas: All types of broad themes plus the principles that underpin Early year foundation stage; and As specified in the early year foundation stage the requirements details for the development, care, welfare and the learning. The framework of the EYFS is mainly dependent on the four principles, to which many of the participants related to research have many times referred. Mainly these principals are categorised under the four major headings: the single Child, affirmative and the Positive Relationships, Enablement of the Environments, and five Development, Learning (McGee, 2007). Each and every principles of this is dependent and based on the research examples, plus evidence which deals all about the early development and also informing a big strand of the practice guidance. It also is completely understood, all of the four principles and the themes which are very much inter connected to each other, to possible extent and amount which it shall not be much possible to obey to a single one without accepting the others (Wilde and Sage, 2007). How the use of technology to the childrens is supported by the practitioners: The practitioners of the early years, who said that they had the availability of the technology of the touch-screen in their setting, were questioned if they are using any of the below discussed activities for the scaffold childrens technology (McCree, 2014): Selection or suggestion of the exact programme The use of technology to be explained Alternative actions to be suggested Provide feedback Demonstrate how the tools to be used, for an example, how to erase Children to be moved towards the perfect level Helps by an offer after the errors Almost every third of the practitioner engages itself in the above discussed activities while the childrens are to be supported with the use of the technology. The practitioners are engaged in such practices or activities where the most frequent is a programme to be suggested to use (84.6%) (Solvason, 2013), using a programme is to be explained (79.5%) (Solvason, 2013) and after errors offering helps (67.9%) (Solvason, 2013). It is also highlighted by the practitioners that how the software is identified to be used on tablet computers is the main focus of the group. Why children enjoy using tablet computers The happiness of the childrens is to be determined with their engagement (attention, interests and abilities) and how the adult engages themselves with the books (Payler, 2007). We also have the interest in knowing why the practitioners believe that the childrens may enjoy using the technology, which are the tablet and the computers. How one should ensure that both the girls and boys may progress in the six areas learning? All the practitioners were confident about the settings in the supporting learning with both the boys and girls, although many of them referred the difficulties of the boys in achieving their targets of the literacy and mainly the targets of the writing (Durden and Dangel, 2009). Only the setting manager and the two childminders argued for the children to be treated as similar and the rest of them are to be offered with the variety of offers with the successful description of their practices. The very common practices which were used were the external environment, which was found to be mainly focused by all the practitioners. Ethical issues: The act and the power relations nature lies between the toddlers, babies and all young children also practitioners, who were met at the times of the needs to be acknowledged well in the situation of the assessment. The influence or the power of the adult plus the dependency of the childrens makes it much imperative that the issues which are ethical are to be provided with very honest and serious consideration by all of the practitioners (Beith, 2002). It is very much imperative that the practitioners consider so many issues that are ethical when they assess childrens early period of learning. For assessing the learning of the young children plus their development culturally, it is significantly important that the practitioners are competent culturally (Gray, 2012). Role as an early year practitioner: As an early year practitioner one has to plan the activities and to observe the childrens for meeting the development needs of the each and every child. He also has to ensure that the activities are to be risk assessed before to take the place. To create an environment of the home for the babies and to also follow the routines provided by the parents. Also to provide the communication books to the parents, so as to communicate verbally with the parents about the progress of the child progress. Summary and recommendations: In the discussed report a very clear and honest throughout is made, and also in the accordance with a series of the recent surveys performed by the Early year of the foundation stage, that so many of the practitioners in the workforce of children have accommodated the beliefs of their own found them to be very broadly compatible and adaptable (Holman, 2015). Thus, the practitioner has many roles in supporting the learning with and through play. They are well described as the facilitators who enable learning to happen. On the other hand, they should also have a regard to maintaining a balance of the activities which are lead by the childrens and by the adults (Parry, 2014). References Allingham, S. (2003).

Why? Because the YTM is defined as the rate which, if used to discount the bond’s cash flows, gives its price. We could picture it like this: Bond Cash Flows on a Time Scale Each fixed coupon of 10% is discounted back to today by the yield to maturity of 12%: 93. 93% = 10 + 10 + 10 + 110 (1. 12)1 (1. 12)2 (1. 12)3 (1. 12)4 All we are doing is observing the yield in the market and solving for the price. Alternatively, we could work out the yield if we have the price from the market. Bond price calculators work by iteratively solving for the yield to maturity. For a bond trading at par, the yield to maturity and coupon will be the same, e. g. a four year bond with a fixed coupon of 10% and a yield of 10% would be trading at 100%. Note that bond prices go down as yields go up and bond prices go up as yields go down. This inverse relationship between bond prices and yields is fairly intuitive.

This will force its price up until it, too, yields 9%. If yields rise to, say, 11% investors will only be willing to pay less than par for the bond because its coupon is below the market. For a detailed example of the bond pricing process, see Appendix 3. For now, note that the dirty price of a bond is the sum of the present values of the cash flows in the bond. The price quoted in the market, the so-called â€Å"clean† price or market price, is in fact not the present value of anything. It is only an accountants’ convention. The market price, or clean price, is the present value less accrued interest according to the market convention. . Pamp;L sensitivities of a bond As we saw above, the price of a bond can be determined if we know its cash flows and the discount rate (i. e. YTM) at which to present value them. The yield curve from which are derived the discount factors for a bond can itself be considered as the sum of two curves: 1. the â€Å"underlying† yield curve (normally Libor), and 2. the â€Å"credit† curve i. e. the spread over the underlying curve The sensitivity of the bond price to a change in these two curves is called: i. PV01, and ii. CS01 respectively. In terms of the example above, the discount rate of 12% might be broken down into, say, a Libor rate of 7% together with a credit spread of 5%. (Note, in the following, it is important not to confuse the discount rate, which is an annualised yield, and the discount factor, which is the result of compounding the discount rate over the maturity in question. ) In addition to the sensitivities described above, we can also consider the impact on the price of the bond of a one day reduction in maturity. Such a reduction affects the price for two reasons: ) assuming the yield curve isn’t flat, the discount rates will alter because, in general, the discount rate for time â€Å"t† is not the same as that for time â€Å"t-1† b) since one day has elapsed, whatever the discount rate, we will compound it based on a time interval that is shorter by one day The names given to these two sensitivities are, respectively: iii. Theta, and iv. Carry Note that, of these four sensitivi ties, only the first two, i. e. PV01 and CS01, are â€Å"market sensitivities† in the sense that they correspond to sensitivities to changes in market parameters. Theta and Carry are independent of any change in the market and reflect different aspects of the sensitivity to the passage of time. i)PV01 Definition The PV01 of a bond is defined as the present value impact of a 1 basis point (0. 01%) increase (or â€Å"bump†) in the yield curve. In the derivation below, we will refer to a generic â€Å"discount curve†. As noted earlier, this discount curve, from which are derived the discount factors for the bond pricing calculation, can itself be considered as the sum of two curves: the â€Å"underlying† yield curve (normally Libor), and a credit curve (reflecting the risk over and above the interbank risk ncorporated in the Libor curve). The PV01 calculates the impact on the price of bumping the underlying yield curve. Calculation For simplicity, consider the case of a zero coupon bond i. e. where there is only one cash flow, equal to the face value, and occurring at maturity in n years. Note, though, that the principles of the following analysis will equally apply to a coupon paying bond. We start by defining: P = price or present value today R(t) = discount rate, today, for maturity t FV = face value of the bond Then, from the above, we know: P = FV/(1+r(t))^n Now consider the impact a 1bp bump to this curve. The discount rate becomes: R(t) = R(t) + 0. 0001 The new price of the bond, Pb(t), will be: Pb = FV/(1+[r(t)+. 0001])^n Therefore, the sensitivity of this bond to a 1bp increase to the discount curve will be: Pb – P = FV/(1+[r(t)+. 0001])^n FV/(1+r(t))^n Eqn. 1 The first term is always smaller than the second term, therefore: * if we hold the bond (long posn), the PV01 is negative * if we have short sold the bond (short posn), the PV01 is positive We can also see that: the higher the yield (discount rate), the smaller the PV01. This is because a move in the discount rate from, for example, 8. 00% to 8. 01% represents a smaller relative change than from 3. 00% to 3. 01%. In other words, the higher the yield, the less sensitive is the bond price to an absolute change in the yield * the longer the maturity, the bigger the PV01. This is more obvious the longer the maturity, the bigger the compounding factor that is applied to the changed discount rate, therefore the bigger the impact it will have. To extend this method to a coupon paying bond, we simply note that any bond can be considered as a series of individual cash flows. The PV01 of each cash flow is calculated as above, by bumping the underlying yield curve at the corresponding maturity. In practice, where a portfolio contains many bonds, it would not be practical, nor provide useful information, to have a PV01 for every single cash flow. Therefore the cash flows across all the positions are bucketed into different maturities. The PV01 is calculated on a bucketed basis i. e. by calculating the impact of a 1bp bump to the yield curve on each bucket individually. This is an approximation but enables the trader to manage his risk position by having a feel for his overall exposure at each of a series of maturities. Typical bucketing might be: o/n, 1wk, 1m, 2m, 3m, 6m, 9m, 1y, 2y, 3y, 5y, 10y, 15y, 20y, 30y. Worked example: Assume we hold $10m notional of a zero-coupon bond maturing in 7 years and the yield to maturity is 8%. Note that, for a zero coupon bond, the YTM is, by definition, the same as the discount rate to be applied to the (bullet) payment at maturity. We have: Price, P = $10m / (1. 08)^7 = $5. 834m Bumping the curve by 1bp, the â€Å"bumped price† becomes: Pb = $10m / (1. 0801)^7 = $5. 831m Therefore, the PV01 is: Pb – P = $5. 831m $5. 835m = -$0. 004m (or -$4k) Meaning In the example above, we have calculated the PV01 of the bond to be -$4k. This means that, if the underlying yield curve were to increase from its current level of 8% to 8. 01%, the position would reduce in value by $4k. If we assume the rate of change in value of the bond with respect to the yield is constant, then we can calculate the impact of, for example, a 5bp bump to the yield curve to be 5 x -$4k = -$20k. Note, this is only an approximation; if we were to graph the bond price against its yield, we wouldn’t see a straight line but a curve. This non-linear effect is called convexity. In practice, while for small changes in the yield the approximation is valid, for bigger changes, convexity cannot be ignored. For example, if the yield were to increase to 9%, the impact on the price would be -$365k, not -(8%-9%)x$4k = -$400k. Use The concept of PV01 is of vital day to day importance to the trader. In practice, he manages his trading portfolio by monitoring the bucketed yield curve exposure as expressed by PV01. Where he feels the PV01 is too large, he will perform a transaction designed to either flatten or reduce the risk. Similarly, when he has a view as to future yield curve movements, he will position his PV01 exposure to take advantage of them. In this case, he is taking a trading position. ii)CS01 The basis of the CS01 calculation is identical to that of the PV01, only this time we bump the credit spread rather than the underlying yield curve. The above example was based on a generic discount rate. In practice, for any bond other than a risk free one, this rate will be combination of the yield curve together with the credit curve. At first glance therefore, we would expect that, whether we bump the yield curve or the credit spread by 1bp, the impact on the price should be similar, and described by Eqn. 1 above. What we can also say is that, bumping the yield curve, the overall discount rate will increase and therefore, as for PV01: * if we hold the bond (long posn), the CS01 is negative * if we have short sold the bond (short posn), the CS01 is positive From the same considerations as for PV01, we can see that: * the higher the credit spread, the smaller the CS01 * the longer the maturity, the bigger the CS01 In practice, when we look at multiple cash flows, the impact of a 1bp bump in the yield curve is not identical to a 1bp bump in the credit spread. This is because, inter alia: * the curves are not the same shape and therefore interpolations will differ * bumping the credit spread affects default probability assumptions that will, in turn, impact the bond price In general though, PV01 and CS01 for a fixed coupon bond will be similar. The exception is where the bond pays a floating rate coupon. In this case, the sensitivity to yield curve changes is close to zero so, although the PV01 will be very small, the CS01 will be â€Å"normal†. Worked example: A worked example would follow the same steps as for PV01 above, only this time we would bump the credit spread by 1bp rather than the underlying yield curve. Theta and Carry We now look at the two sensitivities arising from the passage of time (â€Å"1 day decay†, to use option pricing terminology). First, let’s calculate what the total impact on the value of a position would be if the only change were that one day had passed. In particular, we assume that the yield and credit curves are unchanged. Again, for simplicity, consider the case of a zero coupon bond i. . where there is only one cash flow, equal to the face value, and occurring at maturity in n years. Again, we note that the principles of the following analysis will equally apply to a coupon paying bond. Following the previous notation, the value (or price) today will be: P(today) = FV/(1+r(t))^n The value tomorrow will be: P(tomorrow) = FV/(1+r(t-1))^(n-1/365)Eqn. 2 There are two differences b etween the formula for the value today and that for tomorrow. Firstly, the discount rate has moved from r(t) to r(t-1). Here, r(t-1) is the discount rate for maturity (t-1) today. We have assumed that the discount curve does not move day on day, therefore the rate at which the cash flow will be discounted tomorrow is the rate corresponding to a one day shorter maturity, today. Secondly, the period over which we discount the cash flows has reduced by one day, from n to n-1/365 (we divide by 365 because n is specified in years). Theta and Carry capture these two factors. P(tomorrow) – P(today) gives the full impact on the price due to the passing of one day. This impact can be approximated by breaking down the above formula into its two component parts i. e. he change in discount rate and the change in maturity, as explained below. iii)Theta As before, we define: P = price or present value today r(t) = discount rate, today, for maturity t FV = face value of the bond In addition, we define: r(t-1) = discount rate, today, for maturity t-1 (e. g. for a bond with 240 days to maturity, if the 240 day discount rate today is 8. 00% and the 239 day discount rate today is 7. 96% then: r(t) = 8. 00% and r(t-1) = 7. 96%) We now define Theta as: FV/(1+r(t-1))^n – FV/(1+r(t))^n We can see that, compared to the formula for the full price impact above (Eqn. ), this sensitivity reflects the change in the discount rate but ignores the reduction by 1 day of the maturity. In other words, Theta represents the price impact due purely to the change in discount rate resulting from a 1 day shorter maturity but ignores the impact on the compounding factor of the discount rate resulting from the shorter maturity. Note that the sign of Theta, in contrast to PV01 and CS01, can be both positive and negative. This is because r(t-1) can be higher or lower than r(t), depending on the shape of the yield curve. That said, in practice, given that yield curves are normally upward sloping, we would expect r(t) to be higher than r(t-1). Therefore Theta will normally be positive. In the same way, if the yield curve is flat, then Theta will be zero. iv)Carry Using the standard notation, we define Carry as: FV/(1+r(t))^(n-1) – FV/(1+r(t))^n Comparing to the formula for the full price impact above (Eqn. 2), we see that this sensitivity reflects the change in maturity on the compounding factor to be applied to the discount rate but ignores the impact on the discount rate itself of moving one day down the curve. In other words, Carry represents the price impact due purely to the change in discount factor resulting from a 1 day shorter compounding period but ignores the impact on the discount rate resulting from the shorter maturity. Where discount rates are positive (r(t) gt; 0), Carry will always be positive since the first term will be larger than the second. Using the Taylor expansion, we can obtain a simplified approximate value for Carry. Remembering that: 1/(1+x)^n = 1 – n. x + (1/2). n. (n-1). x^2 †¦ we have: Carry = FV. 1-(n-1/365). r(t)) – FV. (1-n. r(t)) = FV. r(t). 1/365 Note that r(t). 1/365 would represent one day’s â€Å"interest† calculated on an accruals basis since, in the case, the yield equals the coupon rate. (Note, where a position is accounted for on an accruals basis, and therefore valued at par, the yield will always equal the coupon. ) In other words, this definition ties in to the intuitive idea of carry that we have from, say, a de posit where the carry would be equal to one day’s interest, based on its coupon. We can also see that Carry is directly proportional to the yield. We have now seen that, between them, Theta and Carry attempt to capture the two components affecting the price move arising from the passing of 1 day, all other factors being kept constant. There will be certain â€Å"cross† effects of the two that will not be captured when performing this decomposition. In other words, Theta + Carry will not exactly equal the full impact (as per Eqn. 2). The difference, however, will not normally be material. In general, for a long bond position, both Theta and Carry will be positive as, with the passing of one day, not only will the annualised discount rate be less (reflecting the lower yield normally required for shorter dated instruments) but the compounding factor will be smaller (reflecting the shorter maturity). Worked example: Assume we hold $10m notional of a zero-coupon bond maturing in 240 days and the yield to maturity today is 8%. Also, the yield today for the 239 day maturity is 7. 96%. Theta = $10m/(1. 0796)^(240/365) $10m/(1. 08)^(240/365) = $23,159 Carry = $10m/(1. 8)^(239/365) $10m/(1. 08)^(240/365) $20,047 Theta + Carry = $43,205 To compare, the full price impact of a 1 day â€Å"decay† is: $10m/(1. 076)^(239/365) $10m/(1. 08)^(240/365) = $43,113 Summary We have now analysed the key sensitivities that explain the 1 day move in a bond’s mark to market value. To summarise some of the main features; for a long bond position: PV01 / CS01: * negative * for a fixed coupon or zero coupon bond, PV01 and CS01 will be similar * the higher the yield/credit spread, the smaller the PV01/CS01 * the longer the maturity, the bigger the PV01/CS01 for a floating rate coupon (with a Libor benchmark), PV01 will be very small but the CS01 will be â€Å"normal† Theta * positive * the flatter the curve, the smaller the Theta Carry * positive * proportional to the yield 3. Extension to interest rate swaps In essence, all the above applies equally to interest rate swaps (IRSs) when calculating/explaining daily Pamp;L. We start by noting that an IRS is simply the exchange of two cash flows, one fixed and one floating. Extending the analysis we made for bonds, we can say: a) The PV01 of the floating rate leg will be close to zero. This is as noted for a floating rate bond. In both cases, as the yield curve changes so do the expected future cash flows but, at the same time, so will the discount rates at which they are PV’d. The two effects will broadly cancel out. (The PV01 will not be exactly zero because, once the Libor fixing occurs, the next cash flow becomes fixed and therefore effectively becomes a zero coupon bond, on which there will be PV01. ) b) The fixed leg is similar to the fixed coupon stream on a bond and can be considered as a series of zero coupon bonds. Therefore the exact same analysis as applied to bonds above will apply to the fixed leg. An IRS that ays floating and receives fixed will have a PV01 sensitivity similar to that of a long bond position. c) IRSs are normally interbank trades where it is assumed that there is no credit risk over and above Libor. Therefore, the CS01 will be zero. d) Theta and Carry may be either positive or negative. Appendix 1 : Date Conventions There are several methods for computing the interest payable in a period and the accrued interest for a period. A particular method applied to a transaction can affect the yield of that transaction and also the payment for a transaction. Counting the Number of Days The conventions used to determine the interest payments depend on two factors: 1) The number of days in a period and 2) The number of days in a year. The conventions are: 0 Actual/360 1 Actual/365 : sometimes referred as Actual/365F (seldom used now) 2 Actual/Actual 3 30/360 European: sometimes referred to as ISMA method (30E/360) 4 30/360 US (30U/360) The first three methods (Actual/360, Actual/365 and Actual/Actual) calculate the number of days in a period by counting the actual number of days. For each method the number of days in a year is different. Actual/365 and Actual/Actual are similar except: 1. Periods which include February 29th (leap year) count the number of days in a year as 365 under Act/365 and 366 under Act/Act; 2. Semi-annual periods are assumed to have 182. 5 days under Act/365 and however many actual days under Act/Act. Eurobond markets use the 30E/360 basis. This calculation assumes every month has 30 days. This means that the 31st of a month is always counted as if it were the 30th of the month. For 30E/360 basis, February is also assumed to have 30 days. If the beginning or end of a period falls on a weekend the coupon is not adjusted to a good business day. This means that there are always exactly 360 days in a year for all coupons. For example a coupon from 08-November-1997 to 08-November-1998 of 5% is a coupon of 5%, even though 08-November-1998 is a Sunday. There is no adjustment to the actual coupon payment. The various European government bond markets are described below: Country| Accrual| Coupon Frequency| Austria| Act/Act| Annual| Belgium| Act/Act| Annual| Denmark| Act/Act| Annual| Finland| Act/Act| Annual| France| Act/Act| Annual| Germany| Act/Act| Annual| Ireland| Act/ActAct/Act (Earlier Issues)| AnnualSemi-Annual| Italy| Act/Act| Semi-Annual| Luxembourg| Act/Act| Annual| Netherlands| Act/Act| Annual| Norway| Act/Act| Annual or Semi-Annual| Portugal| Act/Act| Annual| Spain| Act/Act| Annual| Sweden| Act/Act| Annual| Switzerland| Act/Act| Annual| United Kingdom| Act/Act | Semi-Annual| Appendix 2 : Calculating Accrued Interest Even though Eurobond coupons are not adjusted for weekends and holidays, the accrual of a coupon for any part of the year has to use the correct number of days. The difference between European and US 30/360 method is how the end of the month is treated. For US basis the 31st of a month is treated as the 1st of the next month, unless the period is from 30th or 31st of the previous month. In this case the period is counted as number of months: | 30/360 European| 30/360 US| Beginning DateEnding Date| M1/D1/ Y1M2/D2/Y 2| M1/D1/Y1M2/D2/Y 2| If D1 = 31| D1 = 30| D1 = 30| If D2 = 31| D2 = 30| If D1 = 31 or 30Then: D2 = 30Else: D2 = 31| The difference occurs when the accrual period starts and ends at the end or beginning of a calendar month: European and US 30/360 Examples Start| End| European| US| Actual| 31-Jul-01| 31-Oct-01| 90| 90| 92| 30-Jul-01| 30-Oct-01| 90| 90| 92| 30-Jul-01| 01-Nov-01| 91| 91| 94| 29-Jul-01| 31-Oct-01| 91| 92| 94| 01-Aug-01| 31-Oct-01| 89| 90| 91| Euro money markets: 0 Day count basis: actual/360 1 Settlement basis: spot (two day) standard 2 Fixing period for derivatives contracts: two day rate fixing convention Euro FX markets 3 Settlement timing: spot convention, with interest accrual beginning on the second day after the deal has been struck 4 Quotation: ‘Certain for uncertain’ (ie 1 Euro = x foreign currency units) U.

It matures on 4 Feb 2006 and has a coupon of 5%.

In the case of Bunds, the day-count convention is the Act/Act convention. Appendix 1 contains more details of date conventions it is recommended that you read this at the end of the module. The part of a year between the settlement date (27 July 2001) and the next coupon (4 February 2002) is: Day Count 192/365 (ie Actual days/Actual days) = 0. 5260 The price of the first coupon can therefore be calculated in the following way: PV of First Coupon = 4. 8873% All of the other cash flow present values are calculated in the same manner. Adding them up gives us the price of the bond. Accrued interest is calculated from 04 February 2001 to 27 July 2001 (173 days) : Accrued Interest Accrued = 5% x 0. 47397 = 2. 3699% There is more detail on Accrued interest in Appendix 2. It is recommended that you read it at the end of this module. Notice that the quoted price of the bond (the ‘clean price’) is 102. 2651% not 104. 6350% (which is the ‘dirty price’ or invoice price ie the price actually paid for the bond). The dirty price is the sum of the present values of the cash flows in the bond. The price quoted in the market, the so-called â€Å"clean† price or market price, is in fact not the present value of anything. It is only an accountants’ convention. The market price, or clean price, is the present value less accrued interest according to the market convention. Practitioners find it easier to quote the clean price because it abstracts from the changing daily accrued interest (i. e. it avoids a â€Å"saw-toothed† price profile).
