Construction began in 1978 but was only completed only in July 1980. Architectural design called for three suspended walkways spanning the 37-m distance between the tower and the function block. Actual construction resulted to the 3th floor and 4th floor walkway hanging from the ceiling. The 2nd floor walkway was directly below the 4th floor walkway and was hanged from the latter so as to simplify construction. (Gibble, 1986) With just over a year in operation, the Hyatt Regency Hotel would be the venue for one of the most catastrophic structural collapse in U.S. history.

The 2nd floor walkway was directly below the 4th floor walkway and was hanged from the latter so as to simplify construction. (Gibble, 1986) With just over a year in operation, the Hyatt Regency Hotel would be the venue for one of the most catastrophic structural collapse in U.S. history. On the 17th of July, 1981, almost 2000 people gathered in the atrium to watch a local radio station's dance competition. The 4th, 3rd and 2nd walkways were gradually jam-packed with people as they watch the activity in the lobby below which was also full of people. At about 7:05 PM, a loud crack echoed throughout the building followed by the crashing of the 2nd and 4th floor walkways to the ground. Official figures of casualties were 114 dead and 200 injured. Figure 1 shows pictures of the site of the collapse and the third walkway still intact. (State of Missouri, 1985) The original structural engineering drawings for the Hyatt project stated that the three walkways spanning the atrium area of the hotel were to be built using W16x26 wide flange beams along either side of the walkway and were hung from a box beam made from two MC8x8.5 rectangular channels, welded toe-to-toe.

Advising Boeing And Airbus On Foreign Exchange Risk Finance Essay

Advising Boeing And Airbus On Foreign Exchange Risk Finance Essay BOEING: Boeing is the worlds largest aerospace company. Being a leading manufacturer of commercial jetliners, it is a top US exporter. It provides tailored services that include commercial and military aircraft, satellites, weapons, electronic and defense systems, launch systems, advanced information and communication systems. (Boeing, 2010). The company has it corporate offices in Chicago and also employs more than 159,000 people across the United States and in 70 countries, also has nearly 12000 commercial jetliners, in service worldwide, which is roughly 75 percent of the world fleet. (Boeing, 2010). AIRBUS: Airbus is a leading aircraft manufacturer owned by European Aeronautic Defense and Space Company (EADs), a global leader in aerospace defense and related services. Having its headquarters in Toulouse, France, it has fully owned subsidiaries in the United States, China, Japan and Middle East. It has it spare part centers in Hamburg, Frankfurt, Washington, Beijing and Singapore, training centers in Toulouse, Miami, Hamburg, and Beijing (Airbus, 2011). The company has 150 field service offices around the world and employs a total work force of 119,000 and has presence on every continent (Airbus, 2011). The major competitor of Airbus is Boeing Company. FOREIGN EXCHANGE RISK: Foreign exchange risk is defined as the risk that an investor will have to close out a long or short position, in a foreign currency at a loss due to an adverse movement in exchange rates. It is also known as currency risk or exchange-rate risk. (Investopedia, 2010). Simply put it is the effect that fluctuations in foreign currencies or exchange rates that affect the business entity. It is evident that large corporations like Boeing and Airbus that have operations in many countries are exposed to foreign exchange risks. It mainly arises due to difference in the currencies in which the company bears its operating or production costs and the currency in which the company receives payments from its clients. Boeing being a US company, it reports its financial transactions in US dollars. The input output is priced in US dollar which is a globally accepted currency. So even if it does trading in other countries, it receives payments in US dollars. Hence it is exposed to low forex risk. Airbus being a French company, it reports its transactions in Euros. Input or output is been priced in Euro in the domestic market, while in the world market is been priced in dollar which is globally acceptable currency and this exposes the company to high forex risk because Euro is not a global currency. We summarize it through following table: Company Currency of Costs Currency of Revenue Match/Mismatch Boeing US Dollar US Dollar Match between currencies. Airbus Euros US Dollar (assume 60%) Euros (assume 25%) Others (assume 15%) Mismatch of currencies. TYPES OF EXPOSURES: TRANSACTION EXPOSURE: Transaction exposure measures changes in the value of financial obligations incurred before a change in exchange rates but to be settled after the change.(Hagelin, 2003). It is the risk of changes in exchange rates between the time that a good is sold and the time that payment is received in foreign currency. For Airbus: As explained above the currency costs of Airbus are in Euros while cost of revenues is mostly in US dollars and some in Euros. This mismatch is clear from the annual report of the company according to which the operations of the group are mainly concentrated in different countries such as China, United States, India and Middle East; hence the payments are done in US dollars. This explains that Airbus has a high transaction exposure towards US dollar. Any fluctuations in the rate of US dollar against the Euro would affect the profit margin of the group. The long term contracts that must be honored at future rates are the other causes of transaction risk to the Euro. Though sometime the profits are being locked in by using long term contracts for e.g. for spare parts, there is an opportunity cost involves as the value of Euro or the price of commodities may increase. (Chester Chronicle, 2008) For Boeing: The cost of revenues as well as production, are denoted in US Dollars. Hence there is a perfect match. So even if the company has operations in many parts of the world such as Australia, Canada, China, India, Italy, Japan, Russia, and UK, the transaction exposure is less. Even if there is dissimilarity in the currency when Boeing sells its product to the different countries, the value is adjusted depending upon the countrys currency. The exposure arises due to variation in the currency rate, mainly of US dollar with other currencies. The danger here would be that the currency of the other country may strengthen or weaken to the corresponding US dollar. (Kascey, 2011). Consider the USD depreciates by 30%. The US currency would be under-valued, so this would lessen the profit margin of Boeing from payments received. But it would also reduce its cost of production. Thus this would hugely benefit for Boeing. On the other hand it would be very problematic for Airbus, as it would affect only the revenues and not the production costs. The decreased profits would cause a huge problem for Airbus. However, if USD value appreciates 30%, it would be of tremendous benefit to Airbus as the profits would be enhanced because of overvalued US dollars. Boeing would have to face the problems of increased cost of production but they would be backed off by the fact that payments would also be received in appreciated currency. TRANSLATION EXPOSURE: It is the risk that when the results of foreign subsidiaries are consolidated into the parents currency, translational gains or losses will result between reporting dates. The effects of translation risk are normally seen in the income statement and balance sheet. For Airbus: It deals mainly in aerospace, defense and commercial services. The Airbus commercial contributes 59% to the Companys revenue in 2009. (Airbus Annual report, 2009) The Company has a huge translation exposure, owing to the fact that it reports its earning in Euros. Transactions of its foreign subsidiaries, in foreign currencies other than the Euro are translated into Euro at the prevailing foreign exchange rate as at transaction date. It is mainly to the US Dollar as the trading in the industry and international markets is basically in US Dollar while the company reports its earnings in Euros. The translation risk of the company is evident in 2008 when the company had a decrease of 1% in revenue of à ¢Ã¢â‚¬Å¡Ã‚ ¬43.265 million due to an unfavorable impact of the US Dollars. Furthermore, in 2007, their chairman- Mr. Louis Gallois in his estimation said every Euro appreciation of 10 cents against the USD is a cost of à ¢Ã¢â‚¬Å¡Ã‚ ¬1B to the company based on the fact that Airbus costs are denominated in Euros while the major share of its revenues are in USD. Airbus also holds a substantial US Dollar denominated assets that are subjected to translation risk. (http://hedgecurrencyrisk.com/36/foreign-exchange-risk-can-be-huge-fortunately-it-can-be-managed/). For Boeing: It deals in commercial and military aircraft, satellites, weapons, electronic and defense systems, launch systems, performance based logistics and training. Of this, commercial airplanes contribute 49.8% of the companys revenues (Boeing Annual report, 2009). Boeing does not have any translational exposure. This is only because the companys trading in international markets is mainly in US Dollars and the company reports financial data in US Dollars only. ECONOMIC EXPOSURE: It is the change in the net present value of future cash flows of the firm as a result of unanticipated changes in real exchange rates. It gives an idea of the potential volatility of the company. For Airbus: Economic exposure of the company is substantially important due to the geographical locations of companys operations. The operating costs are mainly in the Euros and in some other currencies in small portions. The earnings are in US dollars in majority. So if the Euro depreciates by 30% against the USD, its operating costs would relatively go down and it would gain cost advantage. Also its reported profits in Euros would increase due to exchange rate. And if the Euro appreciates by 30% against the USD, it will be facing a huge economic exposure as the operating costs would increase substantially and the reported earnings in Euros would also be less. For Boeing: With 82% of the employees of the company based in America and remaining 18% employees in other locations like India, New Zealand etc, majority of operating costs are in US dollars. So Boeing Company would pay employees mainly in USD while a little portion in other currencies also. The Boeing Company receives its revenue in USD only. Because of this match, any increase or decrease in USD would accordingly increase or decrease both the operating costs as well as profits. Hence the exposure is small and easily manageable, as they are already in USD denomination. COMPARISON CHART: From the above explanation, the exposures of the 2 companies can be summarized by the following table: Company Transaction Translation Economic Boeing Small Easy to manage Does not exist. Small but Manageable Airbus Big Very Difficult to manage High Difficult to manage. Huge. Very difficult to manage INTERNAL HEDGING: Internal hedging means using techniques available within the company or group to manage exchange rate risk. These techniques do not operate through the foreign exchange market and therefore they avoid associated costs. However, this does not mean they are costless. INTERNAL HEDGING TECHNIQUES: MATCHING RECEIVABLES AND PAYABLES: There is no problem if the receivables and payables are in the same currency. If the receivables and payables are in different currencies (mismatch) then there is a risk involved in it. (Joseph, 2000). Airbus operations in US would insulate its risks, as the cost of operations in USD is matched by payment in USD; gained from various services and selling various products in US itself. Fluctuations in other currencies will be negligible as the company will not have to pay operating costs in USD with Euro. In order to provide insulation towards risk in various other countries Airbus can obtain revenue in domestic currencies to pay operating costs in different currencies, payables and receivables for example. As a result of this economic risk can be minimized. (Joseph, 2000) However, this matching of receivables and payables will succeed only to a certain extent. As Airbus would have to borrow Euros with the currency received from other countries in order to bear the operating costs in its own parent company- France. In case of Boeing, this is not required as the company already has a perfect match between the currencies of its trade receivables and payables. CENTRALIZED AND DECENTRALIZED TREASURY FUNCTION (MULTILATERAL NETTING): Airbus with its centralized treasury function utilizes multilateral netting, which is one of the forms of internal hedging against foreign exchange exposure, in order to reduce risk. Multilateral netting is found commonly in Enterprise Wide Risk Management (EWRM) where the parent companys subsidiaries would report the forecasted payments and receipts in the foreign currencies and estimated current exposures to them. After taking internal hedging into account the central treasury calculates the net exposure of the company towards each currency. And it makes use of external hedging to hedge residual exposures. In order to have exchange controls as well as clear understanding of taxation in their respective countries; multilateral netting requires subsidiaries of the group to have a standardized budget reporting periods. The savings gained through the implementation of EWRM information system are also important and are enough for the cost to offset. (Aucoin, 1990). The main advantage of EWRM also includes reducing the capital costs by managing the volatility of earnings. This is made possible through internal rate risk and external hedge of dangerous exposures towards foreign exchange. ERM maximizes the portfolio effect and even helps organizations to exploit natural hedges as stated in capital asset pricing model. (Aucoin, 1990). Hence multilateral netting is applicable to Boeing. As multilateral netting is most commonly found in EWRM, by managing the volatility of earnings it reduces the capital costs. Thereby the risk of Boeing is also reduced. CURRENCY OF INVOICING: The choice of currency which international trade is invoiced is of high implication for Airbus and Boeing due to the nature of their products and services. In trying to avoid foreign exchange risks, both companies adopt currency of invoicing by choosing which currency to be used in international trade. The strategy would be helpful to both companies only when properly planned. Assume Boeing just got a contract with British airways to build five 747s and one is to be delivered each year for the next 5 years. We assume the rate to be 10 million per plane. If Boeing can negotiate and adjust the terms of the invoice, it can shift, share or diversify the currency risk involved in this transaction; which would be an added advantage to the company. To transfer the risk, Boeing can invoice the transaction in USD, then it has eliminated currency risk for itself, however, it has shifted it to British Airways. Assume $ =$1.80, then British Airways has an $18 million account payables and Boeing has an $18 million account receivables. To share the currency risk between both companies, British Airways can share the risk by invoicing 50% of the transaction in USD and the other 50% in British Pound (BP), i.e. $7.5m + £5m for each planes. The risk can even also be reduced by diversification through the payment of the transaction in various currencies based on the negotiation between the two companies. By so doing, Boeing has managed the currency risk. Airbus in similar situation can do the same but this time the currency involved will be Euro and British Pounds or several other currencies in case of diversification. (http://spruce.flint.umich.edu/~mjperry/466-13.htm). ASSET AND LIABILITY MANAGEMENT: Asset and liability management (ALM) is basically a technique of risk management designed so as to earn an adequate return while maintaining a comfortable surplus of assets beyond liabilities. Boeing and Airbus do use this risk management technique to address foreign exchange risk and even operational risk and it also includes hedging where they can hedge against movements in fuel prices. Boeing and Airbus can manage their asset and liability in such a way as to: Increase their overall earnings Ensure efficient use of their capital and assets Manage the associated risk in a cost effective way. (http://www.investorwords.com/285/asset_liability_management.html). LEADING AND LAGGING: Leading is an internal hedging technique that is the acceleration of payment of companys obligation (e.g., payment to suppliers) before the due date while lagging, also internal hedging techniques, is the delay of payment of a companys obligation past its due date. (http://www.angelfire.com/ca/finrisk/Leading.html) For example, when Airbus or Boeing expects the currency (Euro) or (USD) respectively to appreciate in value, they may accelerate (leading) this obliged payment and realize the payment before the currency appreciates. In the same manner, when the value of the currency is expected to decrease in value, they may delay (lagging) payments so as not to make a loss in the transaction. (Victor P and Yann S, 2003). CONCLUSION: In conclusion, we say that Foreign Exchange Risks depend upon the currency of costs and currency of revenues. Any difference within them is going to expose the company to Forex risks. The Forex risk that BOEING is exposed to is less mainly owing to the match between its input and output pricing currencies. While AIRBUS is exposed to huge risks as there is variation in the currencies of its costs and revenues. Also BOEING has Maintenance Contracts with companies and contracts with its Government to supply Military Planes due to which its risks have a backup from their Government in case of Financial Crisis. However AIRBUS doesnt have any such backing from its Government. This coupled with the high risks that it is exposed to; pose a grave threat for the company in case of financial crisis. The Internal Hedging mentioned above though useful for the companies are subjected to their effective and timely. And Airbus would be better naturally hedged against the risks by converting to repor t its financial transactions in US dollars than Euros.

The Evolution of Change in Pride and Prejudice Essay -- Literary Analy

Pride and Prejudice, by Jane Austen, is a remarkable story showing the complications between men and women before and during their time of falling in love. The plot is based on how the main characters, Elizabeth Bennet and Fitzwilliam Darcy, escape their pride, prejudice and vanity to find each other; however, both must recognize their faults and change them. Jane Austen follows the development of Elizabeth’s and Darcy’s relationship in how they both change in order to overcome their own vanities and be able to love each other. Mr. Darcy is very proud and vain man. Darcy’s pride occurs because his family allows him to follow his principles â€Å"in pride and conceit† (Austen 310). Elizabeth decides soon after meeting him that he is a despicable man, much too abrupt and overweening, and obsequious to be liked by anyone, and lacking even the most basic social skills of the time he is very laconic with everyone The gentlemen pronounced him to be a fine figure of a man, the ladies declared he was much handsomer than Mr. Bingley, and he was looked at with great admiration for about half the evening, till his manners gave a disgust which turned the tide of his popularity; for he was discovered to be proud, to be above his company, and above being pleased; and not all his large estate in Derbyshire could then save him from having a most forbidding, disagreeable countenance, and being unworthy to be compared with his friend. (58) Not only does Elizabeth see Darcy as prideful, but the other characters do as well. Darcy’s pride results in his alienation from the others. Darcy has such a high opinion of himself that he creates a pariah reaction from Elizabeth. Elizabeth has her issues with her prejudice against Mr. Darcy and hi... ...After the proposal they talk about their past relationship by having a very benign conversation, and many misunderstandings are cleared â€Å"In vain I have struggled. It will not do. My feelings for you will not be repressed. You must allow me to tell you how ardently I admire and love you† (Austen 179).Their marriage is presented in a positive light because they have had to work hard to achieve it. Pride and Prejudice is an apt name for the book, since these notions permeate the novel thoroughly, especially in the views of Elizabeth and Darcy. Eventually when Elizabeth accepts Darcy’s final proposal we. Even after they both confess their love for each other; they pose and answer questions for each other. This shows that from the beginning to end, Darcy and Elizabeth have gone through major changes by putting aside their pride of themselves and prejudices for others.

Metapath’s capital structure Essay

Questions: 1. Analyze Metapath’s capital structure, in particular the various forms and prices of preferred stock from the previous rounds of financing. How has this capital structure affected the offer from Robertson & Stephens? How would RSC’s participating preferred interact with the other tranches of preferred stock? Up to the date in issue, Metapath has raised $9m in four rounds of financing, of which two occurred simultaneously in the beginning. The two participating investors, Bessemer and STI, which supplied the initial funds, received redeemable preferred for the total amount of $1.6m, the third and fourth rounds brought in $1m and $7m respectively (in both cases preferred convertible were issued), with the calculated price for common being the same for the first three rounds ($1.05) and higher ($1.62) for the fourth round. In case of non-conversion, the last issue was supposed to be paid out first, then the last but one, finally, the first two issues, on a pro rata basis. All of the issues had demand registration rights provision, however, the third and the fourth issues, had more leeway in the exercising of the rights (not only on request of 50%+ of all the issues, but also after-IPO or specific date (July 31, 1999), whichever is earlier), thus protecting the interests of the holders. That said, in fact the holders of the two first issues in many respects enjoyed the position of debt holders, with a scheduled payment of principal and dividends. Given the structure and the fact the managers hadn’t invested from their own pockets, RSC suggested investment in participating convertible preferred shares supposed to protect RSC from possible early sale, which would enrich the management disproportionally and leave RSC abused. Through PCPT, RSC would be able to keep both liquidation preference (with the right to receive the first payment in the amount of invested capital and accrued, not unpaid dividend (8%), before any other security holders receive their part) and equity participation along with other investors (after payment of similar to its own liquidation preference), thus, staying in a highly beneficial position. 2. How do you analyze the RSC offer? In particular, what is the value of the  participating preferred feature of the RSC syndicate? What are the risks to the Metapath shareholders if the board accepts the RSC offer? Even though the company has only projected its activity one quarter forward, is it possible to assess the reasonableness of the valuation? (The ten-year treasury rate in September 1997 was 6.21%). To value the participating feature, first, calculate the options’ values for $11.75% and $87.75 million exercise prices. For calculation, assume: ten-year option price; 40% volatility (corresponding to the middle stock volatility range 20-40%); abovementioned exercise prices ($11.75% and $87.75 million); valuation of $87.75 million is reflective of a true â€Å"asset† value; interest rate of 6.21% (as suggested). Apply Black-Scholes model to receive prices of $81.44 and $49.44 million for the two strikes respectively. For $11.75 is 13.4% of post-money $87.75, the price of the issue is $10.91 and $6.62 million respectively; hence, the participation feature’s value is c. $4.29 million. Therefore, the corresponding share of the company, which makes choice irrelevant is $81.44*0.134/$49.44=22%, that is concession of 22% of the company without the participation feature will make Series E holders equally happy, the corresponding price is 0.134/0.22*$6=$3.65 per share. Acceptance by the board of the RSC’s offer will put Metapath shareholders will add a new senior holder to claim the proceeds, both in case of early liquidation and in case of successful exist. This offer will reduce shareholders’ wealth not only by capital dilution, but also by the absolute amount of investments of Series E holders even in the case of future success. With negative earnings and absence of predictable cash flows, one can do the rough check on the basis of P/Sales ratio (given both companies’ (Metapath and Celltech) similar capital structure, the proxy seems reasonable). With the last quarterly figures as of June 1997, when numbers were available for both Celltech and Metapath, and considering the market cap of Celltech of approximately 260 million, the valuation of around 130 million could be used, which means the company might be worth more. The projections per se, however, don’t tell the story as the two segments (system sales and services) are expected to demonstrate different dynamics, so further investigation is needed. A cautionary note on Black-Scholes model application should be made: 3. Is the Celltech offer reasonable? How should the Metapath board view the Celltech stock? What are the risks for the Metapath shareholders if the board accepts the Celltech offer? While the Celltech’s offers seems to be more reasonable in terms of price offered, the shareholders may face additional risks, including the risk of Celltech’s stock price. While possible liquidity within near future (90 days plus other possible restrictions, which is considerably less than its own IPO in 1+ years) as well as lack of dilution appealed to the managers, the fluctuation in the price of Celltech may wipeout the fortune (the stock had only a short history and the view of insiders doesn’t seem to strongly support Celltech). Furthermore, the fit of the Metapath and Celltech’s businesses is questionable, with Metapath potential possibly higher than that of Celltech, which on the other hand may have a limited upside. 4. If you were on the Metapath board, which option would you support? While the offer of RSC is restrictive in many ways, it is more attractive for a team that will manage to perform. With a set of potential liquidity and financial risk questions, which may arise from Celltech’s financing, Metapath board should not only consider the price, but also other terms (which eventually will incentivize the management in the long-term success and keep its interest in business). With this in mind Metapath board will be better off with the RSC’s proposal, rather than Celltech’s.

States of Consciousness essays

States of Consciousness essays Numerous factors determine when and why you feel tired, full of energy, and hungry. A person's state of consciousness and awareness varies throughout the day and depends on a person's activity, environment, and time clock. As a human we have what is called circadian rhythms, which simply explains our daily highs and lows. An example of your basic up and down rhythm would be the sleep/wake cycle. Sunlight regulates the sleep/wake cycle by causing the suprachiasmatic nucleus to decrease its production of melatonin in the early morning and increase it in the evening. Melatonin is a hormone that if increased in blood levels makes an individual drowsy or tired and if decreased will make them more alert. Certain individuals will experience that their biological clock is often out of sync. This can be explained sometimes from either jet lag, working the night shifts or graveyards, and Monday-morning fog. Sleep in itself has its own biological patterns and rhythms. Hans Berger introduced the electroencephalograph to us so that we would be able to measure the patterns and rhythms of sleep through a record called an EEG. Two different patterns of sleep are REM sleep and NREM sleep. The NREM sleep actually has four stages involved in it. During the first stage a person becomes slightly drowsy because of the mixture of alpha and theta brain waves. At the second stage, an individual tends to have bursts of brain activity for a short time, which in terms are called sleep spindles. The second stage also involves theta brain waves and the beginning of delta waves. The third and fourth stages of NREM sleep are often referred to as "slow-wave sleep". Both of these stages are measured by the amount of delta brain wave activity. During REM sleep, the sleeper is unconsciously active. His eyelids may flutter, he may have increased heart rate, and occasional muscle spasms. The two basic sleep the ories are the evolutionary and restorative t ...

How to Be Prepared for Freshman Year of College

How to Be Prepared for Freshman Year of College Did you know, that approximately one third of students who enrol in college drop out during or immediately after their freshman year. This can largely be attributed to the fact that starting college is such a huge transition for students. It can often be the first real taste of independence a young person has and that comes with responsibilities they might find overwhelming. College life is very different to high school, but if you start out having made appropriate preparations for Freshman year then you are more likely to survive! What to Bring with You to College One of the big questions that most new college students have is what they should bring to college with them and how to pack all that. For many Freshmen this will be their first time living away from their parents, so it can be a pretty overwhelming prospect! A great way to prepare is to make a list of things that you think you will need at college. Start with the basics. You will need things like: bedding for your dorm room crockery and silverware to eat of and of course things like cleaning supplies, towels and other basic items. However, you are also going to need a selection of personal items too. These will include: clothing toiletries books music and other personal belongings. A tip for students who move to another city: If you are moving out of state for college then you are also going to need to take appropriate clothing items. If you know there will be cold winters, then pack a warm coat and boots. Similarly, if there is likely to be a hotter climate than at home you will need lighter clothing. Take a Piece of Your Home With You Everything that we have mentioned so far has been fairly practical in nature. However, one of the most important things that a freshman student needs to pack when heading off to college is going to be a special item that reminds them of home! This could be an ornament with sentimental value, a favorite family photograph or maybe even just something that represents your home town. It is perfectly natural to feel a little bit home sick when you head off to college. However, having a small token to remind you of the people you love will bring you some comfort. How to Prepare for Studying in College So, you are all packed up and you have everything you need for college life, but are you prepared for the actual academic aspect? Many freshmen are astounded by just how different college is to high school and it is a good idea to do some research so that you fully understand what you are getting yourself into.
