Valuation Report of Two Degree Mobile Limited †Free Samples

Question: Discuss about the Valuation Report of Two Degree Mobile Limited. Answer: Brief Overview of Two Degrees Mobile Limited This report provide discussion in the valuation of Two Degree Mobiles Limited which is a company operating primarily in New Zealand. The company engages in the business of telecommunication and its been serving the customers since quite long. In the recent years, the growth of the company has been phenomenal. Its revenues and the earnings before depreciation interest and tax have been observed to be increasing. This growth is putting the company in a favorable position in the market and this is the reason that the companys stock may be valued upside (2degreesmobile, 2017). Description of the Valuation Approach There are various models and techniques that could be applied for the purposes of valuation of the companys stock, for example, PE multiple model, dividend discount model, discounted cash flow model, and net assets model (Shim Siegel, 2008). The choice of a particular model or technique would depend upon the prevailing circumstances and the purpose of valuation. In the current case of Two Degree Mobile Limited, the valuation models such as discounted cash flow model, PE multiple model, and net assets value have been applied in order to value the stock of the company. As per the net assets value method, the value of stock of Two Degree Mobile Limited is arrived at $0.28 as shown in the table given below: Net assets value $'000 Total assets 573,608.00 Less: Outsider liabilities (461,614.00) Net assets 111,994.00 No of shares 403,809.00 Net assets value per share 0.28 However, this method of valuation is least preferred because it does not take into account the market value of the assets. It provides only the book value of the stock (Poitras, 2010). As per PE Multiple valuation model, the stocks value of the company has been arrived at $0.71 as shown in the table given below: PE Multiple PE ratio of competitor (Chorus Limited) (Yahoo finance, 2017) 21.5 EPS of Two Degree 0.03 Stock of Value of Two Degree 0.71 In this model, the PE ratio of the competing company namely Chorus Limited has been used to compute the stocks price of the company. It is assumed in this model that the company which is under valuation will also carry on the same PE ratio. The reliability of the results under the PE ratio will depend upon the characteristics of the competing company. If the characteristics of the competing company are similar, the value of the stock would be more reliable (Poitras, 2010). Under the discounted cash flow model, the value of the companys stock is computed with reference to the present value of the future cash flows that the business will generate for the shareholders. Under this method, the company stocks value has been arrived at $0.23 as shown in the table given below: Free Cash Flow for Equity Model Operating cash flows of 2016 107,705.00 Growth rate assumed 20% Return on equity (for discounting) 11.92% Year Free cash flows ($'000) PVF@12% Present value 2016 107,705.00 0.893 96,165.18 2017 129,246.00 0.797 103,034.12 2018 155,095.20 0.712 110,393.70 2019 186,114.24 0.636 118,278.96 2020 223,337.09 0.567 126,727.46 554,599.42 Value of debt 461,614.00 92,985.42 No of shares ('000) 403,809.00 Value per share ($) 0.23 Reverences 2degreesmobile. 2017. 2degrees FY15 results strong growth continues Revenue lifts 43.1% - EBITDA up 43.9% - mobile network reaches 95% population coverage.

The Impact of Mobile Devices on Cybersecurity

Introduction Computing devices and the internet are two of the most important inventions of the 21st century. These technological breakthroughs have had a great impact on the personal and professional lives of people all over the world. Mobile devices are some of the equipments that utilize computing technology and the internet to provide communication services.Advertising We will write a custom essay sample on The Impact of Mobile Devices on Cybersecurity specifically for you for only $16.05 $11/page Learn More Many organizations have exploited computing devices to increase their productivity. The last decade has witnessed a prevalence of mobile devices in the corporate environment. Glisson and Storer (2013) state that mobile devices have become ubiquitous in the information rich corporate environment with most corporations increasing their usage of these devices each year. This observation is corroborated by Friedman and Hoffman (2008) who declare that mobile devices have become important tools for organizational productivity. While mobile devices have increased the efficiency of employees by enabling them to access organizational information and services at any time and from any location, they have created some security concerns. Mobile devices have a potentially negative impact on the cyber security of an organization and as such, special attention should be given when using mobile devices in the organization. Security Impact of Mobile Devices The very popularity and extent of the use of mobile computing devices and the internet creates a special vulnerability to businesses. Computing devices and the internet have been used expansively by businesses since their invention in the mid 20th century. Many businesses exploited the efficient information processing ability of computers to gain a competitive advantage. Historically, computing devices were restricted to desktop systems that could only be used within the organization†™s environment. Wired technology was the primary means through which the system communicated (Bernik Markelj, 2012). However, there have been incredible developments in technology recently, in the form of wireless technology and mobile computing, which has changed the manner in which organizations access their information. Mobile communication began as a voice service and over the decades, it expanded to include data transmission and today we have 4G mobile communications (Dong, Joo, Chae, Wan, Yoo, 2013).Advertising Looking for essay on other technology? Let's see if we can help you! Get your first paper with 15% OFF Learn More These developments have made it possible for employees to have constant access to data and information. Purchases of mobile devices have already reached the billions and these devices have surpassed the personal computer as the prevalent method for accessing the internet (Patten Harris, 2013). This prevalence of mobile devices has exposed organizations to a wide number of security risks. In addition to the popularity and widespread use of computers by organizations, the ease of use and the compact nature of these devices is another thing that increases their vulnerability to attack. Mobile devices introduce security risks from the physical loss of the devices as employees move from the workplace to their home or client location. This threat of loss is arguably the most important cyber security risk since it can expose the organization to significant losses. Employees store important information in their devices to enable them to work outside the office. Loss and theft of the hand-held device can lead to significant damage to the organization. Friedman and Hoffman (2008) document that an organizations sensitive or intellectual property can be accessed by cyber-criminals once the devices are stolen. Keunwoo, Woongryul and Dongho (2012) confirm that there have been numerous cases of confidential business information bei ng leaked through mobile devices. In addition to this, the devices can expose the company to external attacks. Since the devices might be linked to the organizations database, they might provide an intruder with access to the domain and server system of the organization. When using non-mobile desktop systems, the risk of theft is minimal since most organizations implement good physical security to their offices. For sensitive information, organizations utilize state of the art security measures including biometric security systems. Besides the risk of being stolen, mobile devices also expose the organization by decreasing its ability to protect itself from cyber attacks. The internet is rife with security risks ranging from viruses, worms, and hacking attacks. An organization has to employ security solutions to protect its IT infrastructure from these threats. When dealing with non-mobile desktop systems and servers, the organization can implement a perimeter defense such as firewal ls and intrusion prevention systems (Glisson Storer, 2013).Advertising We will write a custom essay sample on The Impact of Mobile Devices on Cybersecurity specifically for you for only $16.05 $11/page Learn More These security measures ensure that the organizations computing infrastructure is safe from attacks. However, these strong security solutions cannot protect a device once it is outside the corporate perimeter. The mobile devices therefore suffer from an increased vulnerability to external attacks. Another way in which the security of an organization is compromised due to mobile devices is by the introduction of the risk of interception of communication. Mobile devices make use of some form of wireless communication. These communication formats include cellular radio, wireless LAN, and Bluetooth communication. Bernik and Markelj (2012) note that the internet is a crucial element of mobile devices with almost all of these devices providing a wir eless connection to the internet. The various wireless communications available have differing levels of security. Friedman and Hoffman (2008) states that in the non-mobile environment, the organization can impose stringent security protocols to the wireless networks. This security measures render the wireless network secure from external penetration. However, outside the controlled corporate environment, the mobile devices make use of unsecure networks including public Wi-Fi. Malicious elements can easily intercept the communication from these unsecure connections. In addition to the risk of interception, mobile devices cause a negative security impact by increasing risk of access to sensitive information by unauthorized persons. In many causes, employees use their personal devices for business and personal purposes. This convergence of use presents a problem since the device might be handled by the employees’ friends who are not supposed to handle the organization’s information. Bernik and Markelj (2012) observe that when wireless mobile communication devices are used, there is a blurring of the line between business and personal communications. This lack of boundaries can lead to sensitive corporate information being accessed by unauthorized parties through the mobile devices. Addressing the Security Issues Dealing with the cyber security risks introduced by mobile devices is imperative is organizations are to enjoy the benefits of these devices. A number of solutions have been proposed to mitigate or eliminate the security risks. Glisson and Storer (2013) state that organizations should implement specific security policies for mobile devices. All employees should be required to comply with the safety regulations.Advertising Looking for essay on other technology? Let's see if we can help you! Get your first paper with 15% OFF Learn More These regulations should include preventive measures and protocols for device use outside the corporate environment. Bernik and Markelj (2012) assert that by implementing security regulations for mobile devices, an organization can ensure that all information technology is used safely. Another way in which the security risks can be addressed is by having the IT department develop and implement a mobile device management (MDM) system that will ensure that the organization is able to comprehensively manage its employees’ devices. Keunwoo et al., (2012) state that the mobile device management system should be able to monitor mobile access, identify threats and provide appropriate protection. Being able to identify the mobile devices increases the level of control the organization has over its IT resources. MDM can also assist in preventing compromised mobile devices from accessing the network (Patten Harris, 2013). This effectively reduces the risks that compromised devices mig ht introduce into the main system. Conclusion Mobile devices introduce numerous cyber security risks to an organization that utilizes them. It began by defining mobile devices and highlighting why their usage has become prevalent in many organizations today. It then set out to show some of the inherent risks introduced to the organizations IT infrastructure by the devices. From the discussions presented in this paper, it is evident that mobile devices present risks in the form of unauthorized access to sensitive information contained on the device, attacks from malicious elements, and ease of interception of data due to reliance on unsecure networks. Addressing these cyber security risks is critical if organizations are to enjoy the many benefits of having their employees utilize mobile devices. The paper has shown that mobile devices can be safe if users are educated on the security risks and the devices are used in compliance with stringent safety regulations. However, if these me asures are not employed, these devices will continue to be the cause of great security risks to companies. References Bernik, I., Markelj, B. (2012).

Tiny Tim Essays

Tiny Tim Essays Tiny Tim Paper Tiny Tim Paper In this paragraph I will focus on the character of Scrooge how he starts to realise his social responsibility. Dickens made Scrooge the main character to represent all the rich people in London, so if he could change Scrooge, he thought he could change all the rich people in London, and to help the poor. At the beginning of the novel Scrooge can be described as:- A squeezing, wrenching, grasping, scraping, clutching old sinner. This range of adjectives show what a man Scrooge was. Also this simile shows what Scrooge was like: Hard sharp as a flint. His views on Christmas and on giving money to the poor are very negative. When the members of a charity come to collect money, Scrooge uses humour to express his views:- Everyone who likes Christmas should be buried with a stake of holly through their heart, and should be boiled with their Christmas pudding. This shows what Scrooge thinks of Christmas. Visits from the ghosts help Scrooge realise his social responsibility by showing him what will happen in the future, if he does not change his ways. The ghost of Christmas past takes Scrooge back into episodes from his past life to show him his mistakes. When Scrooge was a boy he was very lonely and he was always by himself, then later Scrooge says:- Nothing, there was a boy singing a Christmas Carol at my door last night. I should have given him something. This shows that Scrooge is thinking of that boy as himself and knows what it is like to be lonely, and regrets not giving him something. Also Scrooges sister, Fran was very kind to him, and rescued him at Christmas, then when the spirit asks him if he has any relatives he replies:- Scrooge seemed uneasy in his mind, and answered briefly Yes. This shows that Scrooge is remembering how much he loved his sister, and how badly he has been treating his nephew, Fred. Also then they go to Scrooges old bosss Christmas party, his old boss Mr. Fezziwig invites everyone round, stops all work, treats Scrooge very well, he brought in a fiddler to play music, there is lots of food drink, and everyone is happy jolly. Then suddenly Scrooge says:- I should like to be able to say a word or two to my clerk just now. This shows Scrooge starting to think of other people, and how badly he treated Bob Crachet. After that suddenly Scrooge breaks up with Belle(Scrooges girl friend), Belle says:- But if you were free today, tomorrow, yesterday can even I believe that you would choose a dowerless girl. This shows that Belle is letting Scrooge go, because he will not get a dowery, a dowery is when the father of the bride gives the husband money to take her away. Also a few years later, Belle had a child with someone:- He thought that such another creature, quite as graceful and as full of promise, might have called him father. This shows that Scrooge regrets breaking up with Belle, and wants he to be her husband, and the childs father, so Scrooge is very jealous. In this paragraph I am going to analyse the character of Tiny Tim and why he is significant. When Tiny Tim enters he is described as:- Alas for Tiny Tim, he bore a little wooden crutch, and had his limbs supported by an iron frame. This shows that Tiny Tim is disabled and cant look after himself. Dickens made Tiny Tim a child because people feel more sympathy towards children. Plus Tiny Tim represents all the poor people and children who need help around the world. Tiny Tim is Bob Crachets son, later Bob talks about his son to his wife, he says:- He hoped the people saw him in the church, because he was a cripple. This shows that Tiny Tim wants people to remember Jesus at Christmas through him. Tiny Tim makes Scrooge change by making him realise how poor him and his family are. But the Crachet family are not greedy though; Nobody said or thought it was a small pudding for a large family. This shows that the Crachet family were very grateful for what they had. Tiny Tim also likes to says:- God bless us everyone. This shows Tiny Tim is thinking of others a lot of the time. Near the end of the chapter, Scrooge and the spirit are talking about Tiny Tim:- What then? If he be like to die, he had better do it, and decrease the surplus population. This shows the spirit is using Scrooges own words back at him when he was talking to the charity workers. Tiny Tim helps Scrooge to change by making him realise how badly he has been treating Bob Crachet, and that if Scrooge does not pay his clerk more salary then Tiny Tim will die, because the Crachet family need the money for more food and medicine. Scrooges nephews views about social responsibility are very different from Scrooges, because Fred does not only care about himself and his money, he cares of others and helping others:- And therefore uncle, though it has never put a scrap of gold or silver in my pocket, I believe that it has done me good.

Adam And Eve The Duality Of Humanity Religion Essay

Adam And Eve The Duality Of Humanity Religion Essay Paradise Lost’s Adam is a rational, clever and trustworthy character who has an amazing rapport with the highest power, God. It can even be argued that before he fell, his was the epitome of humanity, as perfect a human as ever existed. He shares this trait with Eve who is the most perfect and complete woman. This view has been reciprocated by many religious denominations but each has interpreted it in their own unique ways; from Calvinists to puritans to Milton each has interpreted the story of Genesis in their own unique way. Like Adam who was perfect, to the belief that eve was flawed, each has built their own mythos around the story of the genesis of mankind. The Adam represented in Milton’s Paradise Lost is an exceedingly rational being, and can understand greatly sophisticated and complex ideas nearly instantaneously. However this perfection hides several deep and critical flaws present within his character. His character and insight is demonstrated when after ob serving Raphael’s descent into Eden, Adam orders eve to, â€Å"go with speed, / And what thy stores contain, bring forth and pour / Abundance, fit to honor and receive / Our Heav’nly stranger† (V, 313-316). To which Eve answers, â€Å"Adam, earth’s hallowed mould, / Of God inspir’d, small store will serve, where store, / All seasons, ripe for use hangs on the stalk† (V, 321-323). These word which at first seem stiff and of an overly formal method, nonetheless helps reveal the relationship of Adam and Eve. Adam is in charge, but his request for Eve to prepare a meal is not in any way dismissive. She understands that and her response, is in accord with that message. This transitory conversation is not that of a master and servant but of two people who hold themselves in equal regard. His relationship with Eve is not the only conversation between equals, as he also talks with Raphael as an equal. He converses with the archangel Raphael as an eq ual both, socially in his standing, and intellectually in his ability to clearly understand the meanings behind the Raphael’s words. However this ends after Adam’s fall from the grace of god. After his fall Adam loses his pure intellect and his rationality leading him to brash and increasingly non-rational actions, stripping him of his ability to converse with the angels as an equal. Adam’s greatest flaw is his unequivocal love for his wife Eve. He falls I love merely upon seeing her for the first, and even confesses to the archangel Raphael that his attraction is nigh overwhelming. Though warned by Raphael to keep his dangerous emotions in check he completely disregards Raphael’s earnest urgings. After Eve eats from the Tree of Knowledge of good and evil, quickly devours a fruit from the same tree in order to prevent him from being separated from her even momentarily. Eve has become an indispensable companion in his life and he will do anything in order to prevent himself from being separated from his only love. His other major weakness is his insatiable curiosity. He manipulates the angel Raphael to extract more information from him,

The witness beneficiary rule in S.15 of the Wills Act 1837 is outdated Essay

The witness beneficiary rule in S.15 of the Wills Act 1837 is outdated and in need of reform.Discuss this statement with reference to relevant academic and judicial comment - Essay Example 15 of the Wills Act 1837 which have prompted lawyers, paralegals, legal practitioners and academicians to observe that there is a need for amends, so as to have the pitfalls amended. One of the drawbacks in the Witness Beneficiary Rule in s. 15 of the Wills Act 1837 is the failure to capture the complexities that accompany the law of testation. Specifically, the Witness Beneficiary Rule negates a situation whereby a beneficiary of a will gets married to the main witness, 10 years after the signing of the will. This is a complex issue because the Witness Beneficiary Rule assumes that there is always a distinction between a beneficiary and a witness and this assumption fundamentally underpins and informs the legitimacy of the exaction of the will, upon the death of the testator. Instead, what is captured as a limitation, known as Gifts to an attesting witness to be void states that: if any person attests the execution of any will of any will to whom or to whose legal spouse any beneficial legacy, device, interest, estate, gift or appointment, of or affecting any real and/ or personal estate [apart from and except directions and charges for the payment of debt(s)], shall be thereby made or given such legacy, device, interest, estate, gift or appointment, shall, so far only as concerns such person or legally recognised spouse or any person claiming under such a person [a legally recognised spouse], be totally null and void, and such a person so attesting shall be admitted as a witness, to prove the execution of such will, or to demonstrate the invalidity or validity thereof, regardless such legacy, device, interest, estate, gift or appointment that has been mentioned in such will1. The provision above is therefore clearly derelict of the consideration of the circumstances that may impede the exaction of the Witness Beneficiary Rule in s. 15. To the effect of the above, solution to the complication above will be pegged on the circumstances

The Baroque Era Term Paper Example | Topics and Well Written Essays - 500 words

The Baroque Era - Term Paper Example In comparison to the forms of music preceding the Baroque music, the Baroque music is more intense, ornate and texturized in a lavish manner. The melodic line of the Baroque music is immensely decorated and has a rich counterpoint. A myriad of traits define the music of the Baroque era that include but are not limited to the basso continuo’s use and a faith in the affections’ doctrine which enable the composers to incorporate their feelings and emotions into their work. One of the most distinguishing features of music in the Baroque era is the emphasis it places upon the pace, volume and texture of the music. These features were altogether non-existent in the conventional music from the late Renaissance. Moreover, the Baroque music replaced the austerity of the early Renaissance and the Medieval style with the color of the instrument and the use of voice. In the Baroque era, there was an abundance of the secular forms of music and their use was just as much as that of t he liturgical styles of music. Imitative polyphony was one characteristic that reflected in most of the preceding music eras as well as in the Baroque era. It was used in the musical lyrics. On the contrary, the homophonic style was gaining increased attention and use in the music of the Baroque era, unlike the preceding music eras. Along with the employment of the homophonic music in the Baroque era, several innovative types of polyphonic music were surfacing in this era as well. Composers in the Baroque era were of the opinion that the counterpoint’s art.
