Introduction: Oxford dictionary defines risk as à ¢Ã¢â ¬Ã
âa situation involving exposure to dangerà ¢Ã¢â ¬? or à ¢Ã¢â ¬Ã
âexpose (someone or something valued) to danger, harm, or lossà ¢Ã¢â ¬? (Oxford Dictionary). For a business entity à ¢Ã¢â ¬Ã
âRisksà ¢Ã¢â ¬? are connected to possible uncertainties that can result in negative effect on the entity. With the emergence of World Markets and various types of risks, risk management has become an integrated part of firms today. Different types of risks require different methods to handle, prevent or sometimes to absorb and benefit from risks. The downfall of risks has always been highlighted however they do have some arbitrage that results in potential gains. The Basel Committee that was formed in 1974 laid the regulatory framework for Financial Risk Management. (McNeil, Frey and Embrechts, 2005). Basel II (2001) defines Financial Risk Management to be formed of 4 steps: à ¢Ã¢â ¬Ã
âidentification of risks into market, credit, operational and other risks; assessment of risks using data and risk model; monitoring and reporting of risk assessments on a timely basis and controlling these identified risks by senior management.à ¢Ã¢â ¬?(Alexander, 2005). It thus determines the probability of a negative event taking place and its effects on the entity. Once identified risk can be treated in following manners: Eliminated altogether by simple business practices. These are the risks that are detrimental to the business entity. Transferred to other participants. Actively managed at firm level. (Alexander, 1996). The risks basically depend on the time value of assets. Moreover with the increased level of multinational functioning of business entities and the highly volatile nature of markets, risk management has now become a critical part of running the business. It therefore becomes essential to understand as well as analyze the various factors that determine risks and the preventive measure s implemented against them. Also the hedging techniques being considered do not always ensure profits. The research would thereby include a detail study of the effectiveness of the methods implemented. One more important factor is the cost incurred. Risk management incurs certain costs and the process would therefore prove to be futile if the costs incurred donà ¢Ã¢â ¬Ã¢â ¢t offer proportionally benefits. Literature Review: Market Risk constitutes of commodity risk, interest risk and currency risks. Commodity price risk includes the potential change in the price of a commodity. The rising or falling commodity prices affect the producers, traders and the end-users of the various commodities. Moreover if they are traded in foreign currency, there arises the risk of currency exchange rate. These are normally hedged by offering forward or future contracts at fixed rates. This is especially important for commodities like oil, natural gas, gold, electricity etc whose prices are highly volatile in nature. (Berk and Demarzo, 2010) Interest Risk relates to the change in interest rates of bonds, stocks or loans. A rising rate of interest would effectively reduce the price of a bond. Increased interest rates result in increasing the borrowing costs of the firm and thereby reduce its profitability. It is hedged by swaps or by investing in short term securities. Currency risks arise from the exceedingly vola tile exchange rates between the currencies of different countries. For e.g. Airbus, an aircraft manufacturing company based in France requires oil for its production. Oil being traded in US dollars and the company doing trading in Euros, has a foreign exchange risk. It would be therefore beneficial for Airbus to enter a forward contract with its oil suppliers. Options are another way of hedging against currency risks. (Berk and Demarzo, 2010). Forward contracts, Futures and Options are called the Financial Derivatives and are used largely to reduce market risks. Walsh David (1995) explains that if two securities have same payoffs in future, they must have same price today. Thus the value of a derivative moves in the same way as that of underlying asset. This is called arbitrage. Hedging of risks is nothing but the holder of an asset has two positions in opposite directions. One is of the derivative and opposite position is on the under-lying asset respectively. As such if t he value if the asset decreases then value of the derivative will also decrease. But the change in value is off-set by the opposite positions to each other. Thus risk is reduced. This is called hedging. Long Hedge refers when an investor anticipates increase in market price and therefore buys future contracts. Short Hedge is when an investor already has a futures contract and expects the value of asset to fall and therefore sells it beforehand. (Dubofsky and Miller, 2003) Long Hedge Short Hedge Change in value of position Change in price Change in value of position Change in price Fig.1 Hedging (Dubofsky, D and Miller, T. Jr. 2003) Forward Contracts- These involve buying or selling specific asset at a specific price at a specified time. It is basically a contract between two parties to trade a particular commodity or asset at a particular rate on a specified time. The buyer is said to be in à ¢Ã¢â ¬ÃÅ"long positionà ¢Ã¢â ¬Ã¢â ¢ while the seller hols the à ¢Ã¢â ¬ÃÅ"short positionà ¢Ã¢â ¬Ã¢â ¢. These are Over the Counter (OTC) Derivatives. These are used for locking-in the price and require no cash transfers in the beginning, thereby involve credit risks. Their main feature is the flexibility as forward contracts can be tailored as per the requirements of the traders. They are typically used to hedge the exchange rate risks. (Claessens, 1993) Futures- These are more standardized than the Forward contracts. They are traded at Foreign Exchanges. The standardized contract specifying the asset, price and delivery time is either bought or sold through broker. The delivery price depends on market and determined by the exchange. The default risk in futures is minimized due to clearinghouse. It acts as centred party and does the à ¢Ã¢â ¬ÃÅ"marking to marketà ¢Ã¢â ¬Ã¢â ¢ of tradersà ¢Ã¢â ¬Ã¢â ¢ account; by doing profit-loss calculations daily. Initial margin amount is required and futures hence involve margin calls. Minimum credit risk is involved; but being standardized contracts, these cannot be tailored to individual demands. (Hinkelmann andÃâà Swidler, 2004). Futures could be contracts on real assets for e.g. gold, oil, corn etc. or they could also be contracts of financial nature for e.g. currency, interest rates etc. (Tamiso and Freedman, 1995). Fig.2: Hedging through Futures. (Walsh, D. 1995) Options- The holder can buy from or sell to, the asset at a strike rate at a future maturity date. However the holder of the option has no moral obligation to do so. The cost of buying the option involves a premium which is to be paid up front. The option that enables the holder to buy an asset is called Call option while in Put option the holder is able to sell the asset. (Claessens, 1993) These can be bought Over the Counter (OTC) at a bank or can be exchange traded options. An American option could be exercised at any time before it expires. On the contrary, a European option has to b e exercised on maturity. Option is normally executed when its strike price is less than price of the stock. However, is the price of the stock is less than the strike price; the holder will not execute the option. Black and Scholes (1973) gave the formula to determine the price of a European option. According to the formula, the value of Call option is given by: where The value of Put option is given by: P = Ke-r (T-t) à ¢Ã¢â ¬Ã¢â¬Å" S + C = N(-d2) Ke-r (T-t) à ¢Ã¢â ¬Ã¢â¬Å" N(-d1) S. Where N (.) is a cumulative normal distribution function s- standard deviation of the share price, rf- risk-free interest rate per annum and t- time to expiry (in years). The above formula, also known as the Black-Scholes option pricing model; is based on the assumptions that the stock doesnà ¢Ã¢â ¬Ã¢â ¢t pay any dividends, it is possible to buy or sell even a single share, there are no costs incurred in these transactions and that arbitrage opportunity doesnà ¢Ã¢â ¬Ã¢â ¢t exist. According to Black and Scholes (1973), à ¢Ã¢â ¬Ã
âthe option value as a function of the stock price is independent of the expected return of the stock. The expected return of the option, however, will depend upon the expected return of the stock.à ¢Ã¢â ¬? Hence as the price of underlying asset increases, the price of option will also increase owing to their linear relationship. Black and Scholes (1972) further carried on various empirical tests to validity of the formula. They observed that price paid by the buyers of the option was higher than that shown by the formula. This was mainly because the transaction costs that are incurred are always paid by the buyers of the options. These costs were found to be high for options of high risks and vice-versa. The sellers of options thus got the price that was predicted by the formula. The case study would make use of this formula to determine the value of options held by the company. Walsh David (1995) exp lains that options have a non-linear relation with payoff. Its payoff increases with the price of the asset if it is in-the-money and has a constant payoff which is the option premium if it is out-of-the-money. On the contrary, futures and forward contracts have a linear relation with the payoffs in both, profit as well as loss. Therefore options might be preferred over futures and forwards for hedging. He further highlights the difference between hedging through futures and forward contracts. While in forward contracts, the company merely sets up a rate for future trading, it doesnà ¢Ã¢â ¬Ã¢â ¢t involve any monetary transfer. Futures however make use of margin account and marking to market is done daily. Hence the results of futures over their time span vary greatly with those of forward contracts. Hence the individual contributions of each to risk management would be calculated during the research. The case study would also include a study the similarities and differences in futures, forward contracts and options and their individual effects on risk management. Data and Methodology: Objectives: The research aims to: Increase the understanding of the factors that determine market risks. Understand the haven provided by financial derivatives against these risks. Have a clear understanding of the methods or risk management techniques. Understand the process of risk management. Understand the intricacies of derivative markets. Data and Methodology: The Research is essentially a case study of Vodafone Group Plc. Primary data would include the information of the forward contracts with service providers, options and futures of the company in the market. Secondary data would be Qualitative in nature, comprising online journals, relative case studies and books. The research would be carried out in the following steps: Depending upon the nature of company, determine that factors that would affect the risk faced by the company. Evaluate the percentage of risk faced by the company. Determine the amount of this risk, which the company would want to hedge. The data would then be utilised to determine the amount of risk hedged by each of the above and then determine the total risk hedged by portfolio as whole. Calculate the cost of hedging the risk. Compare and contrast the findings with the defined à ¢Ã¢â ¬ÃÅ"Effective Risk Management.à ¢Ã¢â ¬Ã¢â ¢ Critically analyze the results. Suggest improvements if any, in the portfolio.

However, the biggest advantage of hiring professionals is their ability to identify and prevent common security threats. Hiring professional accountants and certified computer security specialists helps to prevent many common digital threats. When even the smallest hack or breach is discovered or suspected, take advantage of fraud alerts and business identity protections services. Remain security conscious, and make security practices an essential condition of employment for your staff. The following categories of threats are easily overlooked but easy to remedy with forethought and safe practices. 1.

Worldview ten Commandments and God free essay sample
The overall perspective from which one sees and interprets the world. A collection of beliefs about life and the universe held by individual or a group. This represents the theory which I use to understand, perceive this world. It helps me to function according to the norm. Therefore, I fit nicely in with the status quo and not ruffle any feathers. Or so they believe. PART 2 The Biblical/ Christian worldview of Origin, Identity, Purpose, Morality, and Destiny. 1. The question of origin-ââ¬Å"Where do we come from? How did we come into existence? â⬠Christian believes that God created earth, the heavens and everything in it out of his own will. Christian believe that mankind was created by the one and only sovereign God (Genesis 1:27). The bible states that the process in which God created Adam and Eve (Genesis 2:7-8, 23). Adam was created from the dust off the ground and Eve from Adam. ââ¬Å"God who made the world and all things in it, since he is lord of heaven and earthâ⬠(Acts 17:24-25). Therefore, we all are created by God. 2. The question of Identity-ââ¬Å"Who am Iâ⬠? ââ¬Å"What does it mean to be a human? â⬠ââ¬Å"Are humans more important than animals? Christianââ¬â¢s worldview teaches that God created man (Genesis1:27). We were created in Godââ¬â¢s own image. We were given responsibility over the earth and rulers over animals (Genesis 1:26-28). Since we were created in Godââ¬â¢s image, we are separate from animals and are given the right over animals (Genesis 1:28). We were known to God before our births. 3. The question of meaning/ Purpose- ââ¬Å"Why do I exist? â⬠The original purpose of the first manââ¬â¢s creation was when Adam rebelled against God. Men and women discovered themselves to exist in order to know God, to do his will, to glorify him, and to enjoy him forever (1 Corinthians 13:12). Why do I exist? â⬠We are here because God created men and women to inhabit it (Genesis 1:26-28; 2:7). Also, our purpose is to know Christ, to allow him access to our lives, and to develop a personal relationship with him (John 17:3). We are to love other Christian believers. 4. The question of Morality- ââ¬Å"What is meant by right and wrong? â⬠and ââ¬Å"How should I live? â⬠The basis in which we differentiate between right and wrong is our knowledge of Godââ¬â¢s law. This knowledge comes from two sources revelation and conscience. The bible says that God wrote his law on our hearts (Romatns 2:15). This is conscience. God gave a commandment to Adam and Eve in the garden. He gave ten commandments down to two essential commandments- love God and love your neighbor (Exodus 20). All of these represent Godââ¬â¢s revelation of his law. 5. The question of Destiny- ââ¬Å"Is there life after deathâ⬠ââ¬Å"What will happen to me when I die? â⬠Christians believe in two eternal states for all human beings: Heaven or Hell. Heaven and Hell are both eternally places where people exit in the presence and blessing of God in Heaven (Revelation 21) or in a state of separation from God, being punished in Hell( Revelation 20 11-15) (weirder and Gutierrez pg65). A new heaven and a new earth will come. But the day of the lord will come as a thief in the night , in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up (Peter 2 3:10). Our salvation is a gift to any of us who wants to receive it. Part 3- How might/ should biblical worldview influence the way? A major worldview of mine is to do unto others as you would like done unto you. This is an important factor which I am cognitive of most days. Therefore, when addressing others it is important that I choose my words wisely. There are times it may be difficult and I need to be on a time out, however, this too shall pass. All humans are to be treated with respect, dignity without regard to their religious convictions, race or creed, and their social status. In the political/voting arena, my choice for any particular candidate is, does he/she represent me? Do they represent my views? Will their worldview blend or shatter mine? Shall my family, friends and loved ones be represented as well? Furthermore, shall this candidateââ¬â¢s worldviews affect my life in a positive or negative manner? If any of these questions are received as Nay, then my support is withdrawn. An aunt of mine warns me to turn off the water faucets. It is a bad habit of mine to let the water flow freely as I do other things in the kitchen or house. She further warns that this is wasting water and goes on to explain drought. to me. Her warnings have awakened a new concern for the environment my children and I live in. No longer does the water flow freely. I am becoming aware of my carbon footprint being left on this earth. Therefore, lights are turned off, no littering or polluting our waters. The aerosol can has become an enemy within my household for it is weakening our ozone layers. A future career will be established in the same vein as my choice of political candidates. How will it affect my livelihood? Is there a pension attached. How will my medical needs be met? Will they respect my choice of religions and give me the religious holidays off? The main objective here is, Do not ruffle my feathers. Meaning, do not step on how I view the world. Do not insist I adopt your belief system that does not agree with mine. However, I shall respect your worldview.

Oceanography Chapter 7 Essay Example
Oceanography Chapter 7 Paper An indirect method of measuring ocean current is the use of __________. radar altimeters A large system of rotating ocean currents, usually driven by the major wind belts, is called a(n) gyre The current in the northwestern part of the North Atlantic Subtropical Gyre that transports warm water toward the North Atlantic is called the Gulf Stream The loss of heat from the ocean surface, resulting in a lowered temperature, causes ocean water to become denser A deep and powerful southward subsurface current that flows under the Gulf Stream in the North Atlantic is the North Atlantic Deep Water Thermohaline circulation in the ocean is driven primarily by differences in __________ and __________ among water masses. temperature; salinity To produce a surface current of 1.6 knots in the open ocean, a steady wind of _____ knots would be required. 80 The actual movement of surface water due to Ekman transport in the Northern Hemisphere is about __________. 45 degrees to the right of the wind direction Of the following statements about subtropical gyres, which is/are true? The western boundary current of all subtropical gyres is intensified (it is fast, narrow, and deep).Globally, there are five subtropical gyres.There are four main surface currents in each subtropical gyreThe centers of all subtropical gyres are associated with high atmospheric pressure.The rotation of each subtropical gyre causes a hill of water to pile up within it. Of the following gyres, which one(s) flow in a counterclockwise direction? Indian Ocean Subtropical Gyre, Northern Hemisphere Subpolar Gyres, South Atlantic Subtropical Gyre, South Pacific Subtropical Gyre Of the following surface currents, which one(s) flow from south to north? Peru Current Kuroshio Current the Gulf Stream Of the following surface currents, which one(s) flow generally from west to east?

It is the path that air takes as it moves from high to low pressure, and back to high pressure, in the South Pacific under normal conditions. Why does upwelling occur along the west coast of South America under normal conditions? Winds moving westward in the South Pacific drive ocean currents toward the west; deep water rises to replace water driven westward.

Under which conditions are droughts and wildfires common in Australia? under El Nino conditions What is the overall effect of the stronger than normal trade winds typical of La Nina conditions? lowering of the South Pacific ocean temperature from normal conditions One of the worldââ¬â¢s most powerful currents, located off the east coast of the United States, is the Gulf Stream The Gulf Stream transports warm water into the North Atlantic Fluctuations in the flow of the Gulf Stream current result in curving loops of water known as meanders Ocean frontal systems that spin off from currents such as the Gulf Stream, akin to atmospheric storms, are known as eddies When a meander from the Gulf Stream pinches off into the warm water south of the current, the eddy is called a cold-core eddy or ring The largest of the great ocean surface currents is the West Wind Drift Warm core rings and cold core rings are associated with western boundary currents Indian Ocean currents that are generated by seasonal changes in weather patterns are the __________ and __________ Currents. Somali/Southwest Monsoon During a strong El Nino event, the news media might be expected to cover a tropical cyclone in Hawaii or Tahiti Of the following conditions, which is/are related to strong El Nino events? -increase in sea surface temp. and destruction of coral reefs in the eastern pacific ocean-higher sea levels in the eastern pacific ocean associated with warmer water-increased abundance of hurricanes in the eastern pacific ocean Deep ocean current movement is also known as thermohaline flow Records indicate that the ocean is warming faster in the Arctic polar regions than elsewhere. If that continues, a possible consequence could be slowing of deep ocean circulation, resulting in lower oxygen levels in deep water Of the following statements about deep-ocean currents, which is/are true? -Deep-ocean currents contain water that is high in oxygen. -Deep-ocean circulation is often referred to as thermohaline flow. -The volume of water involved in the downward movement of deep-ocean currents is equal to the flow of 100 Amazon-sized rivers. -Deep-ocean currents are important regulators of global climate.-Deep-ocean currents are initiated by downwelling of cold, dense water near Antarctica and in the North Atlantic Ocean. (deep ocean currents often travel faster than surface currents) The coastlines with the greatest tsunami hazard are most commonly associated with what type of plate boundary? convergent Which of the following statements about earthquakes and tsunami hazards is most accurate? A relatively high number of earthquakes and the greatest tsunami hazard occur along the western coast of South America. Which of the following statements is most accurate about tsunami hazards and the number of people at risk? A low tsunami hazard and a high number of people at risk are present along the coast of the eastern United States. Which body of water is shown to have the greatest amount of coastal pollution? Baltic Sea Surface ocean currents ___. form large rotating gyres in the major ocean basinsare driven by windsare influenced by Coriolis effect Equatorial currents that are part of the subtropical gyres flow ___. Equatorial counter currents between the gyres flow ___ . east-to-west; west-to-east Warm ocean currents ___. are warming than the surrounding water Cool ocean currents ___. generally flow from high latitudes towards the equator The subtropical gyres ___. play a large role in climate Deep ocean currents ___. Deep ocean currents ___.
