FLEXLM ECC问答 (1)readyu 2012.61. FLEXLM是个虾米东西?FLEXlm是应用广泛的License管理工具。
宣称数千家EDA工具采用它管理授权。
FLEXlm对厂商来说,它的优点是证书管理功能强大,支持平台众多。
对最终用户来说,它的缺点是不够友好,比如Windows下,经常由于某些原因,flexlm服务启动错误。
对于破解者来说,它有着为数众多的教本。
维基百科上的条目为:/wiki/FLEXlmFLEXLM本来属于GLOBEtrotter。
Macrovision曾经收购GLOBEtrotter。

Essential Digital Skills - Entry Level 3 指导手册说明书
Essential Digital Skills – Entry Level 3Delivery GuideIntroduction:The purpose of this guide is to give you an overview of how you could holistically deliver the full range of standards, from the Essential Digital Skills through the delivery of a single project.When delivering any qualification, it is always useful to look at the full range of standards and consider how they are or could be linked together to give your delivery a more realistic and holistic approach.A holistic approach will provide you with a structured plan to teach the students how a range of standards work together, providing them with understanding of how skills and knowledge link together in a real life scenario.This approach to delivery will also help prepare your students for their summative assessment. To support this we have structured this guide in-line with the final assessment; giving your students the opportunity explore ideas and develop an understanding of the content, to practice and refine their skills, and gain an understanding of the depth and breadth that will be required in their final assessment. The project consists of six tasks covering a wide range of the standards. Each task includes several activities that students can carry out individually or in groups. If working within a group, we would advise that students contribute to each of the tasks, in order to gain the experience and skills required for the external assessment. The activities are designed to help teach the skills required within each of the tasks and give the opportunity for students to practice before their final assessment.The intention is that the students will be taught a range of knowledge and skills within each of the units and then carry out a series of tasks, linked to a scenario. Completion of each of the tasks successfully will demonstrate understanding and competency of the identified standards.Make-up of the guideThe first section of the guide goes through the scenario and provides details of the company that will form the context of the project.Following this is a pack of teaching and learning activities, structured as 6 tasks, for all the content that needs to be taught, as well as activities to reinforce learning for the scenario.ScenarioYour family are the proud owners of a vintage caravan and plan to run several catering events for local festivals and craft fairs. The festivals are happening near you in Newcastle, North of England. They have asked if you would like to be involved in the business and you have accepted. You are very excited at working in the family business and very keen to get started and help wherever possible.The family have decided on a company name for the business……”Tea To Go”.“Tea To Go” will sell hot drinks such as teas, coffees and hot chocolate as well and selling cakes, sandwiches and scones. The idea is to provide everything needed or a traditional afternoon tea.Project BriefThe family are getting prepared for the first festival event and Brooke Patterson (Manager) has called a meeting. At the meeting Brooke has identified several tasks that need to be carried out before the festival events begin.Through discussion and agreement, you have been allocated the following jobs:Your TasksTask 1 – Search for a new boilerTask 2 – Amend the menuTask 3 – Amend the spreadsheet to show the new prices of the cakesTask 4 – Create a posterTask 5 – Use social media to advertise the eventTask 6 – Email the organiser of the festival to confirm the date and timeTask 1“T ea To Go” needs to purchase a new 10 litre boiler as the existing boiler is unreliable:1.Search the internet and find 3 possible options2.Record your findings in a table, including the website link and the price (minimumof 2 columns)3.Identify your chosen boiler and justify why you have made this recommendation Standards Covered:Extension Activities:Level 1 produce a spreadsheet with the data or a table using word with possible payment options or pricing plans, extended warranty, services etcEmail a short summary to colleagues about the differing options and costTask 2“Tea To Go” has decided to update their menu and add a few more cakes to the menu. It has also been decided that the menu needs to look more attractive and you have been given the responsibility of improving this.1.Open document named “Menu Jan 2020”2.Add the new changes in the relevant sections•Lemon Drizzle Cake - £2.50•Chocolate Brownie - £2.20•Millionaire Shortbread - £3.003.Make at least 2 formatting enhancements to the menu to make it eye catching4.Save the menu with a relevant file nameStandards Covered:Extension Activities:Put together a short presentation to the family and present the new menuSave a PDF versions and share on Social mediaCreate a short promotional voice over and share on YouTube, social mediaTask 3“Tea To Go” have been looking at the prices and a decision has been made to increase the price of all hot drinks. The price list has not been updated since December 2019.1.Open the spreadsheet named “Price List”2.Amend the spreadsheet with the price changes below:•White Coffee - £2.00•Latte – £2.00•Fruit Tea - £2.003.Ensure all data is visible in all columns4.Merge and centre the title5.Format all data6.Make 1 other formatting enhancement to the spreadsheet to make it clear andeasy to read7.Save the spreadsheet with a meaningful filenameExtension Activities:Create a more detailed spreadsheet showing portion cost, retail value, and % profit and a weekly sales chart for each product, calculate busiest quietest daysPresent to family cost and profitTask 4“Tea To Go” are not very good at advertising their services and a decision has been made to create a poster. The poster will be posted in local shops and restaurants and hopes to attract people’s attention that have bought tickets to the festival. “Tea To Go” know that they need to be better with marketing and are relying on you to help with this important role.e suitable software to create a poster2.Insert the company logo from Image fileing the Image file, insert 3 suitable images4.Copy the text from the “information” file5.Evaluate the poster and ensure it is fit for purpose6.Save the poster with a meaningful filenameExtension Activities:Create a version suitable for displaying on social Media, Pinterest, Facebook Linked in for marketing locally, share with friends and family & communityEmail campaign to local medium and large size business include delivery service for office parties and conferencesTask 5“Tea To Go” have never used social media to promote themselves. They recently attended a meeting with the organisers of the event, who told them they had doubled the ticket sales by advertising on Facebook and Instagram. “Tea To Go” have made the decision to advertise on a social media platform and join the 21st century.e the internet to find 3 social media sites, suitable for advertising2.List the 3 social media platforms and identify why you would possibly use theplatform1.Decide on a social media platform in which to advertise the festival2.Create a n exciting post for the festival and “Tea To Go” – encourage people tovisit the vintage caravan for food and drinkExtension Activities:Marketing Campaign on a number social media sites with product launch offers, discount vouchers or codes when visiting the venue at a festival.

The samplingfrequency f S = 1/T S = 1/(25x10–3) = 40 Hz. The digital frequency is Ω = 2πf/f S = 200/40 = 5 rads. The sampled signal is x[n] = 5sin(n Ω) = 5sin(5n).3.17 Check 2π/Ω for each function. The function is periodic if this ratio is rational. (a) 2π/Ω = 2π/(4/5) = 10π/4 = 5π/2This ratio is not rational, so the sinusoid is not periodic. (b) 2π/Ω = 2π/(6π/7) = 14/6 = 7/3This ratio is rational, and in lowest terms. The number in the numerator, 7, is the number of samples before the sequence repeats. (c) 2π/Ω = 2π/(2π/3) = 3This result may be seen as 3/1. Thus, the sinusoid is periodic with period 3.3.18 (a) From the equation for x(t), ω = 2πf = 1000π, so f = 500 Hz. Since seven samples are collected every three cycles, N = 7 and M = 3, so37M N 2==ΩπThis means SS f 5002f f 276π=π=π=Ω. Solving S f 500276π=π gives f S = 1167 Hz. (b) Since f S > 2f, the sampling rate is adequate to avoid aliasing.3.19 (a) The following samples are graphed below.(b) The ratio 2π/Ω is 2π/(4π/5)=10/4 = 5/2. The numerator, 5, indicates the sinusoidal sequence repeats every five samples. Because the denominator of the ratio is 2, these five samples are collected over two analog periods.(c) The analog signal is superimposed over the digital signal with a dashed line in the figure below.3.20 The analog frequency of x(t) is f = ω/(2π) = 2500π/(2π) = 1250 Hz. The digital frequency of x[n] is π/3 radians. These frequencies must be related through the equationSS f 12502f f 23π=π=π=ΩThe solution to this equation is f S = 7500 Hz.

MASCHINE!MASCHINE is a groove production studio that implements the familiar working style of classi-cal groove boxes along with the advantages of a computer based system. MASCHINE is ideal for making music live, as well as in the studio. It’s the hands-on aspect of a dedicated instru-ment, the MASCHINE hardware controller, united with the advanced editing features of the MASCHINE software.Creating beats is often not very intuitive with a computer, but using the MASCHINE hardware controller to do it makes it easy and fun. You can tap in freely with the pads or use Note Re-peat to jam along. Alternatively, build your beats using the step sequencer just as in classic drum machines.Patterns can be intuitively combined and rearranged on the fly to form larger ideas. You can try out several different versions of a song without ever having to stop the music.Since you can integrate it into any sequencer that supports VST, AU, or AAX plug-ins, you can reap the benefits in almost any software setup, or use it as a stand-alone application. You can sample your own material, slice loops and rearrange them easily.However, MASCHINE is a lot more than an ordinary groovebox or sampler: it comes with an inspiring 7-gigabyte library, and a sophisticated, yet easy to use tag-based Browser to give you instant access to the sounds you are looking for.What’s more, MASCHINE provides lots of options for manipulating your sounds via internal ef-fects and other sound-shaping possibilities. You can also control external MIDI hardware and 3rd-party software with the MASCHINE hardware controller, while customizing the functions of the pads, knobs and buttons according to your needs utilizing the included Controller Editor application. We hope you enjoy this fantastic instrument as much as we do.

This man-ual uses particular formatting to point out special facts and to warn you of potential issues.The icons introducing these notes let you see what kind of information is to be expected:This document uses particular formatting to point out special facts and to warn you of poten-tial issues. The icons introducing the following notes let you see what kind of information canbe expected:Furthermore, the following formatting is used:▪Text appearing in (drop-down) menus (such as Open…, Save as… etc.) in the software andpaths to locations on your hard disk or other storage devices is printed in italics.▪Text appearing elsewhere (labels of buttons, controls, text next to checkboxes etc.) in thesoftware is printed in blue. Whenever you see this formatting applied, you will find thesame text appearing somewhere on the screen.▪Text appearing on the displays of the controller is printed in light grey. Whenever you seethis formatting applied, you will find the same text on a controller display.▪Text appearing on labels of the hardware controller is printed in orange. Whenever you seethis formatting applied, you will find the same text on the controller.▪Important names and concepts are printed in bold.▪References to keys on your computer’s keyboard you’ll find put in square brackets (e.g.,“Press [Shift] + [Enter]”).►Single instructions are introduced by this play button type arrow.→Results of actions are introduced by this smaller arrow.Naming ConventionThroughout the documentation we will refer to MASCHINE controller (or just controller) as the hardware controller and MASCHINE software as the software installed on your computer.The term “effect” will sometimes be abbreviated as “FX” when referring to elements in the MA-SCHINE software and hardware. These terms have the same meaning.Button Combinations and Shortcuts on Your ControllerMost instructions will use the “+” sign to indicate buttons (or buttons and pads) that must be pressed simultaneously, starting with the button indicated first. E.g., an instruction such as:“Press SHIFT + PLAY”means:1.Press and hold SHIFT.2.While holding SHIFT, press PLAY and release it.3.Release SHIFT.1.3New Features in MASCHINE2.8The following new features have been added to MASCHINE: Integration▪Browse on , create your own collections of loops and one-shots and send them directly to the MASCHINE browser.Improvements to the Browser▪Samples are now cataloged in separate Loops and One-shots tabs in the Browser.▪Previews of loops selected in the Browser will be played in sync with the current project.When a loop is selected with Prehear turned on, it will begin playing immediately in-sync with the project if transport is running. If a loop preview starts part-way through the loop, the loop will play once more for its full length to ensure you get to hear the entire loop once in context with your project.▪Filters and product selections will be remembered when switching between content types and Factory/User Libraries in the Browser.▪Browser content synchronization between multiple running instances. When running multi-ple instances of MASCHINE, either as Standalone and/or as a plug-in, updates to the Li-brary will be synced across the instances. For example, if you delete a sample from your User Library in one instance, the sample will no longer be present in the other instances.Similarly, if you save a preset in one instance, that preset will then be available in the oth-er instances, too.▪Edits made to samples in the Factory Libraries will be saved to the Standard User Directo-ry.For more information on these new features, refer to the following chapter ↑4, Browser. Improvements to the MASCHINE MIKRO MK3 Controller▪You can now set sample Start and End points using the controller.

Tutorial 使用指南
使用指南(Tutorial)修订版序从首次接触这个软件到现在,有一段时间了。
那时由于急着使用,因此对一些认为不太重要的地方没有进行整理。
后来才发现,其实每一部分都是很有用的。
此修订,一个是将LineSim(Tutorial)与后加的Crosstalk(Tutorial)的目录统一起来,再有就是原文基础上增加了多板仿真(Tutorial)一节。
同样,对于那一时期我整理的BoardSim 、LineSim使用手册,也有同样的一个没有对一些章节进行翻译整理问题(当初认为不太重要)。
而实际上使用时,有一些东西是非常重要的,同时也顺便进行了翻译。
此外,通过使用,对该软件有了更多一些理解,显然以前只从字面翻译的东西不太好理解,等我有时间将它们重新整理后,再提供给初学的朋友。
对在学习中给予我大量无私帮助的Aming、pandajohn、lzd 等网友表示忠心的感谢。

Fog Polygon Volumes 3代码示例用户指南说明书
User GuideFog Polygon VolumesInstructionsThe FogPolygonVolumes3 code sample requires hardware support for vs.1.1 andps.2.0. If hardware supports ps.3.0, the code sample uses a code path that takesadvantage of ps.3.0 features and requires fewer passes than the ps.2.0 path.A technique using off screen render target textures is used to render an undulatingvolume of fog on the floor of the tomb scene. The fog volume is an ordinarypolygon mesh, and it is easily controlled and animated. Figure 1 shows an exampleof how the code sample should look when it starts up. The appearance of the fog isa function of the thickness through the fog that you are seeing at each pixel. Thescale factor for converting thickness to color can be controlled with the Fog ColorScale slider in the controls window.Table 1 lists the controls used for this code sample.Table 1. List of Control KeysKey DescriptionH key Toggles the Control window on and offF1 Lists additional keyboard controlsW, A, S, D First-person shooter type controls to fly around the sceneQ Move camera UpE Move camera DownLeft-Drag Point camera as you look around the sceneFigure 1. Fog Polygon Volume EffectControls Dialog:TechniqueSelects whether to use the ps.2.0 or ps.3.0 code pathShow Fog WireframeIn wireframe mode, the depth buffer is not used, so the fog volume object isvisible through the walls of the tomb scene.Render FogThis checkbox toggles both the animation and render-to-texture operationsused to render the volume fog. In a Debug build of the code sample , theprocedural animation of the fog volume can be a significant bottleneck in thecode sample ’s performance.Dither DepthControls whether or not to dither the depth information used to compute thefog thickness at each pixel. Chances are, you will not be able to notice thevisual difference between the two states in this scene, but without dithering,performance may be faster.Show IntermediatesToggles the display of the off screen render target textures used to compute the appearance of the volume fog objects. With the ps.2.0 path, these targets are 32bpp ordinary textures. With the ps.3.0 path, some of these are floating point (fp16) render target textures which appear much darker.With this display, the upper-left texture is rendered to contain the depth to the nearest solid object in the scene. The upper-right texture contains the sum of depths to all front faces of the fog polygon object or to the nearest solidobject, whichever is closer to the camera. In the ps.3.0 mode, this texturecontains the sum of all front and back face depths. In the ps.2.0 mode, thelower-left texture contains the sum of depths to all back faces of the fogpolygon object or to the nearest solid object.Reload Shaders –Shaders for this code sample live inSDK\MEDIA\Programs\D3D9_FogPolygonVolumes3. These shaders can be edited in an external editor as the code sample is running, and then reloaded into the code sample using this button.Note:You can fly into solid objects and into the fog volume itself. As you do this, one single well-thought-out rendering path properly accountsfor all camera positions and all cases of the fog volume objectintersecting itself and the solid objects in the scene. No special codeor data is required to handle the intersection cases, so the entire sceneis trivial to animate.The visible fog object thickness is converted to color using a simplecolor ramp texture. The visible thickness of the volume at each pixelis scaled and used as a texture coordinate to access the color ramp.NVIDIA Corporation 2701 San Tomas ExpresswaySanta Clara, CA 95050NoticeALL NVIDIA DESIGN SPECIFICATIONS, REFERENCE BOARDS, FILES, DRAWINGS, DIAGNOSTICS, LISTS, AND OTHER DOCUMENTS (TOGETHER AND SEPARATELY, “MATERIALS”) ARE BEING PROVIDED “AS IS."

一个多线程应用程序创建两个或多个线程同时执行任务。
如果你正需要使用多线程,请阅读"你需要多线程吗?",以确定你是否真的需要;这可以避免些麻烦。
程序中的一个线程被称为主线程,也就是在应用程序启动时由操作系统创建的那个线程。
主线程是唯一一个可以更新用户界面组件的线程,否则,应用程序可能会挂起。
其主要思想是:应用程序使用第二个线程在后台处其他事情,同时用户可以继续使用主线程工作。
线程的另一个用途是为了更好的响应应用程序。
如,你创建了一个应用程序,在应用程序启动时,用户按下按钮启动一个大的任务……处理中……之后,程序停止响应,这让用户觉得应用程序假死了,在用户体验上这很不好。

Chapter 4The share market and the corporationLearning objective 1: understand the corporate structure and identify advantages and disadvantages of being a publicly listed corporation• A company that has its shares listed and quoted on a stock exchange is known as a publicly listed corporation.•The main type of equity issued by a corporation is the ordinary share, or common stock.•An investor who purchases shares issued by a company is a shareholder and has an ownership interest in the company.Learning objective 2: consider the origins and structure of a stock exchange•The development of stock exchanges and share markets has supported the rise of the corporation as the dominant business structure.•Shareholders, as equity owners, acquire the right to elect the board of directors of a corporation. •The board of directors is responsible for setting the objectives and policies of the organisation and appointing executive management.•Executive management is responsible for the day-to-day operational and financial management of the business.•The predominant type of company listed on a stock exchange is the limited liability company, where shareholders’ financial commitment to the corporation and its creditors is limited to the issue price of the fully paid shares.•The corporate form allows the separation of ownership and management of an organisation, thereby ensuring that a change in ownership does not directly affect normal business operations. •Listing on a stock exchange affords a corporation access to a greater pool of both equity finance and debt finance. Listed corporations are more able to gain cost advantages from their larger scale.•One potential disadvantage of the corporate form is the agency problem, that is, the possibility ofa conflict of interest between the owners and managers of a firm, such that shareholder valuemay not be maximised.Learning objective 3: discuss the primary market role of a share market, through which corporations raise new equity funding• A stock market serves as the primary market through which shares are initially issued in order to obtain equity finance.•It is this primary market transaction which provides new funding for a corporation and allows increased investment in productive capital and economic growth.•The initial listing of a company on a stock exchange is called a float or an initial public offering (IPO).•Previously listed corporations may issue new shares through a rights issue to existing shareholders on a pro-rata basis, or by placement with institutional investors.•An offer to raise funds from the public must be made through a prospectus.Learning objective 4: discuss the secondary market role of the share market, through which existing shares are bought and sold• A stock market also provides for secondary market transactions in a company’s existing shares. •Liquidity in the secondary markets is essential if investors are to be encouraged to invest in the primary market.•If management is not perceived to be performing in the best interests of shareholders, dissatisfaction may be expressed through the sale of shares. Sufficient share sales will result in a fall in the price of the company’s shares.•Therefore, the secondary market role is important in reconciling the conflicts that may arise as a result of the separation of ownership and management of the corporation.Learning objective 5: consider the derivatives market role of a stock exchange• A derivative is essentially a risk management product that derives its price from an underlying commodity or financial instrument that is available in a physical market.•Standardised, exchange-traded contracts quoted on a stock exchange may include options, warrants and futures.•An option gives the buyer the right, but not the obligation, to buy or sell a specified security at a predetermined price on or by a predetermined date. The buyer pays a premium to the writer of the option.• A warrant also gives the holder the right to buy or sell a security at a specified price on or by a predetermined date.• A futures contract is an agreement between two parties to buy or sell a specified commodity or financial instrument at a predetermined price on a predetermined date. For example, a futures contract may be based on the shares of a listed corporation or on a stock market index. Learning objective 6: explain the interest rate market role of a stock exchange• A stock exchange may also list a range of debt or hybrid securities issued by corporations, financial institutions and governments.•Types of securities include long-term corporate bonds such as debentures and unsecured notes, floating rate notes, convertible notes, preference shares and government bonds.•Listing and quoting of debt securities on a stock exchange adds liquidity to those securities, improves information transparency, lowers the cost of borrowing and provides a wider range of investment choices.Learning objective 7: understand the electronic trading and settlement systems used for share-market transactions•In order for a stock exchange to compete within the global market, it must have systems in place that facilitate an efficient market.•In the Australia, the ASX uses a scripless trading system using uncertificated shareholdings. This enables transactions to take place in T + 3 business days.•The former days of open outcry trading have been replaced with electronic systems.•The ASX trading system is known as CLICK XT/ITS and the settlement system as CHESS. •An investor places a buy/sell order with a stockbroker that has access to the CLICK XT/ITS system. The CLICK XT/ITS system matches corresponding trades, the broker issues a contractnote to the buyer/seller, and the transfer of ownership and value settlement occur throughCHESS.Learning objective 8: recognise the importance of information flows to the efficiency of share markets•For a stock market to be efficient, it must be fully informed.•The listing rules of an exchange will require a corporation to advise the exchange, and therefore the market, of its half-yearly and annual financial statements, plus, immediately it becomesevident, any material change that might affect the corporation’s share price.Learning objective 9: identify the principal regulators that affect the behaviour of participants in the share market•Associated with the flow of information into the markets is the regulation of the markets.•In the first instance, the ASX monitors the activities of markets participants.•At the same time, ASIC supervises the application of the Corporations Act 2001 and the overall integrity of the markets.Learning objective 10: explain the structure and purpose of the private equity market•Private equity is an alternative source of equity funding for a company.•Private equity may be provided for start-up companies, business expansion for existing companies, recovery finance for corporations in financial difficulty, or management buy-outs. •Specialist private equity funds obtain the majority of their funds from institutional investors. •Private equity investment is usually regarded as higher risk.•The principal objectives of private equity funds may be to improve company performance in preparation for an IPO, or the break-up a company so that the parts may be sold separately. Essay questionsThe following suggested answers incorporate the main points that should be recognised by a student. An instructor should advise students of the depth of analysis and discussion that is required for a particular question. For example, an undergraduate student may only be required to briefly introduce points, explain in their own words and provide an example. On the other hand, a post-graduate student may be required to provide much greater depth of analysis and discussion.1. A fundamental characteristic of a publicly listed corporation is the separation betweenowners and managers. Briefly discuss the rights, roles and responsibilities of the shareholders, board of directors and executive management.• a publicly listed corporation is a legal entity formed under the provisions of the corporations law of a nation-state and listed on a formal stock exchange• a shareholder has a right to vote in the affairs of the corporation, in particular vote on resolutions put to a general meeting of the company•shareholders elect the board of directors of a corporation•shareholders, as owners of a company, do not have a right to participate directly in the day-to-day operation and management of the business•the objectives and policies of a corporation are determined by a board of directors•directors have a legal responsibility to ensure that the corporation operates in the best interests of the shareholders•the board of directors appoints an executive management group that is responsible for achieving specified objectives and policies through the management of the day-to-day financial and operational affairs of the company•executive management is responsible to the board of directors. The board of directors reports to shareholders2. Why might a business organisation seek listing as a publicly listed corporation? Include inyour answer the advantages of the corporate form of business organisation.• a publicly listed corporation is a legal entity formed under the provisions of the Corporation Law of a nation-state, and listed on a formal stock exchange•shares can be readily bought and sold in the market without directly affecting the continuing existence of the business•the liability of shareholders for the debts of the business is limited•large amounts of equity funding can be obtained more easily through access to the stock market •investors willing to purchase shares in the knowledge that the stock exchange provides an active secondary market for the future sale of those shares•shareholders can reduce the risks of share ownership by holding a diversified portfolio of share investments•the separation of ownership (shareholders) and control (managers) means that the corporation can choose specialised and skilled personnel to run the business•the corporate form allows for continuity in the activities of the business. The death or bankruptcy of a shareholder will not impact the existence of the business.•the corporate form is almost essential for large-scale undertakings. Corporations gain access to a larger and wider range of equity and debt sources of funds•the separation of ownership and control enables the corporation to plan and implement strategic decisions more effectively•the cost advantages of large-scale production are a further benefit of the corporate form of business organisation.3. Maximisation of shareholder value is a principal objective of an organisation. What is therelationship between this objective and the so-called agency problem?•the maximisation of shareholder value presumes the board of directors will establish appropriate objectives and policies and that management will implement strategies that seek to increase the share price of the organisation•agency theory considers the potential problems that may arise from the separation of ownership and control of a corporation•managers control the day-to-day operation of the business and may not necessarily act in the best interests of the shareholders•for example, managers may maximise their own benefits at the expense of the shareholder, such as increasing staff levels for prestige and power, extending management remuneration schemes, increasing sales at the expense of profitability and sustainability•the board of directors must implement policies that align the interests of management with those of the shareholders•corporate governance policies seek, in part, to address potential agency problems4. List and briefly explain the five principal functions of a modern and efficient stockexchange.•the establishment of markets in a range of financial securities—this includes the primary and secondary markets in equity (ordinary shares); listed debt securities (preference shares, convertible notes, subordinated debt); and derivatives (options, warrants, futures)•the provision of a securities trading system—most modern and efficient stock exchanges have implemented electronic trading systems, for example the CLICK XT/ITS system used by the ASX. Buy/sell orders are placed into CLICK XT/ITS by authorised brokers. The system matches orders and executes the trade•operation of a clearing and settlements system—global competitive forces require exchanges to settle stock transactions within T+3 days. This time line will be reduced even further as systems become even more efficient. The system used by the ASX is known as CHESS. CHESS instantaneously records the transfer of ownership and facilitates the financial settlement of a transaction thus removing the possibility of settlement risk•regulation and monitoring of the integrity of the exchange’s markets—the efficiency and integrity of the market is important. The ASX has its own set of listing rules. The exchange monitors the behaviour of listed companies and authorised brokers, and is able to apply penalties including delisting a company or revoking the licence of a broker•provision of a well-informed market to secure the confidence of all participants—the price of a share is a function of available information about that stock; changes in the current price will be in response to new information coming into the market that will have an impact on the future performance of the listed entity. Clearly it is essential that continuous disclosure of material information changes must be advised to the exchange immediately. The efficiency of the market is a measure of how quickly new information is absorbed by the market and reflected in changes in share prices5. A stock exchange provides a formal market that facilitates the flow of equity funds into thecapital markets. Explain this flow-of-funds process from the perspective of a listed corporation issuing equity securities through the share market.• a stock exchange facilitates the flow of funds firstly, through the primary market issue and secondly, the secondary market trading of existing securities (the secondary market role is discussed in question 6)•the primary market role of the stock exchange facilitates the raising of capital by publicly listed corporations through the issue of new equity-based securities to investors•the principal equity security issued is the ordinary share, or common stock•shares may be issued on the initial flotation of the company (IPO), or by a rights issue to existing shareholders, or by private placement with institutional investors•hybrid securities such as preference shares and convertible notes may also be issued•the primary market issue of new equity is the source of capital funds for the corporation; these funds allow the maintenance and growth of a business•primary market issues facilitate the process of conversion of savings to investment, which theoretically leads to an accumulation of capital capacity, economic growth, increased production and higher levels of employment6. Discuss the secondary market role of the share market and its importance to thecorporation. Demonstrate your answer through the use of examples.•the secondary market role of a share market is to provide an organised and efficient market where existing listed securities may be bought and sold at current market prices•the current market price should reflect the performance outcomes and forecast prospects of individually listed companies within the context of the relevant industry sector, and the domestic and global economies•an efficient share market facilitates transfer of ownership amongst investors and enhances liquidity in listed securities•securities initially issued through the primary market may be subsequently traded through the stock market as a secondary market transaction•secondary market transactions will include a range of securities listed on the exchange, including ordinary shares, rights issues, preference shares, instalment receipts, debentures and notes •economic growth derives from primary market investment, however a successful primary market requires the support of a deep and liquid secondary market•an active secondary market encourages investors to purchase new securities because the investors are confident they will be able to sell those securities in the future in the secondary market quickly at the current market price7. What is meant by the liquidity of the share market? Explain why liquidity in the secondarymarket is important to both shareholders and to the corporation.•liquidity in the share market relates to the ability of the holder of a security to buy or sell listed securities without unduly disturbing the current market price of the shares being traded•the standard measure of share market liquidity is the ratio of the value of turnover to market capitalisation. Market capitalisation is calculated by multiplying the number of shares on issue by their current market price•liquidity in the secondary market for shares encourages investors to initially purchase new issues by corporations. Shareholders are confident that shares may be easily and quickly sold without incurring a capital loss as a direct result of the sale transaction (capital loss/gain may result from other factors such as company performance outcomes)• a liquid share market provides advantages to both the investor (shareholder) and the corporation in that it facilitates the raising of long-term capital while providing short-term liquidity to the investor8. Three equity-based derivative products that may be offered through a stock exchange arean options contract, an equity warrant and a futures contract. Briefly explain the main features of each of these products. Why might an investor use these products?• a derivative is a financial security that derives its price from an underlying commodity or instrument, for example a share listed on a stock exchange•derivatives traded on a stock exchange are standardised exchanges traded contracts •derivatives are designed to facilitate the management of risk exposures•for example, an investor might hedge the risk that a share price may fall by implementing a strategy to lock in the current share price using a derivatives contract•option contract—gives the buyer of the option the right, but not the obligation, to buy (sell) at a predetermined price at or by a predetermined date. A call option is the right to buy; a put option the right to sell. The buyer of the option will pay a premium to purchase the contract from the option writer. The contract price is the exercise or strike price•equity warrant—an equity call warrant gives the warrant holder the right to buy the underlying security (shares) at a particular price, on or before a predetermined date. A put warrant gives the right to sell. A warrant issuer is a third party, such as a bank, authorised by a stock exchange to write warrant contracts•futures contact—an agreement to buy or sell a specified commodity or instrument at a predetermined price and date9. Many market participants lament the disappearance of share-market trading by openoutcry on the floor of the exchange. What has happened to the ‘chalkies’?•in the ‘good old days’, stockbrokers competed through open cry on the floor of the stock exchange to buy and sell listed securities on the exchange•transactions were recorded by stock exchange clerks, in chalk, on a large blackboard which contained all listed companies. Thus the name ‘chalkies’•when the market was particularly active the open cry shouting by the stockbrokers would become quite intense•while the open outcry system is less efficient than technology based trading systems, it certainly provided atmosphere to the market-place•while the majority of exchanges, including the ASX, have disposed of the trading floor, the NYSE has retained a combination of advanced technology supporting continued floor trading.The Chicago Board of Trade and the Chicago Mercantile Exchange still retain open outcry floor trading in commodities and derivative products•therefore, the introduction of technology based trading systems has mostly seen the chalkies disappear10. Electronic trading and settlements systems have been introduced in major internationalstock exchanges, including the ASX. What does this mean, and how do they operate? •scripless share trading has been introduced into a number of share markets in an effort to improve the efficiency of the market’s trading and settlements system•the ASX has introduced a technology based trading system (CLICK XT/ITS) and a settlements systems (Clearing House Electronic Sub-register System—CHESS)•stockbrokers initiate buy/sell orders of their clients by entering the orders into the CLICK XT/ITS system•CLICK XT/ITS matches buy and sell orders and initiates the transaction•under the CHESS arrangements shareholders no longer receive and hold a share certificate, but rather hold uncertificated securities, being an electronic record of shareholdings•the buying and selling of shares is facilitated by a CHESS sponsor such as a stockbroker•the current CHESS arrangements require settlement of a share transaction to occur in three days (T + 3)•the combination of CLICK XT/ITS and CHESS form the basis of the ASX’s strategy to remain an efficient and competitive international stock exchange. The possibility of T+1 settlement is currently being investigated by a number of stock exchanges11. A listed corporation is considering issuing debt securities in the capital markets. Thecorporation is also investigating the possibility of having the debt securities quoted on the stock exchange. What are the advantages to a corporation and a potential investor in having the debt securities listed? What types of securities might the corporation issue? Advantages to a corporation and an investor in listing on a stock exchange include: •transparency—the stock exchange keeps the markets informed•ease of entry and exit—a deep and liquid market using electronic trading (CLICK XT/ITS) and settlement systems (CHESS)•liquidity—existence of price makers and a large pool of investors•listing increases the corporate image and profile in the financial markets•the receipt of a known income stream, being interest coupons•an investment option for surplus funds• a strategic investment option to manage interest rate risk exposures•an opportunity to diversify an investment portfolioTypes of listed securities include:•straight corporate bond—a longer-term fixed interest security that pays periodic interest coupons and repays the face value of the bond at maturity. The bond may have security attached in the form of a charge over the assets of the company (known as a debenture)•floating rate note—a corporate bond that pays a variable interest rate that is usually tied to a published reference interest rate such as LIBOR or BBSW•convertible note—a fixed interest debt instrument that will offer the holder the right to convert the note into ordinary shares of the company at a predetermined price and date•preference share—initially have characteristics of debt in that they pay a fixed dividend, but offer the right to convert into ordinary shares or redeem into cash at a future date12. Define and provide examples of the following:uncertificated shares•ownership of stock listed on an exchange is recorded electronically, for example the ASX no longer issues actual share certificatesshare contract note•advice sent from a stockbroker to a client confirming the full details of a buy or sell transaction that has been carried out by the broker on behalf of the client. Includes details of the stock, the date, the number of shares, the price per share, fees and charges, total cost and settlement date settlement risk•the probability that one party to a buy/sell transaction will not fulfil their contractual obligations.For example, delivery of the stock and transfer of ownership may occur, but financial settlement does not eventuateT + 3 business days•used to describe settlement of a share transaction when transfer of ownership and value will occur on the transaction day plus three dayselectronic sub-register.• a system that facilitates a record of share ownership using an electronic computer-based system, for example the ASX uses CHESS13. (a) Why is the flow of information into a stock exchange important in the efficientfunctioning of a share market?•listed corporations raise their equity funds and part of their debt funds through the issue of securities on a stock exchange•investors purchase these securities because they have confidence in the operation of the primary and secondary markets on the exchange•the current price of a security reflects all known information relevant to that stock•the stock price will change in response to new information coming to the market•therefore, the efficiency at which information is provided to the market and the speed at which it is absorbed will directly affect the pricing of listed securities(b) Identify and explain one standard form of periodic reporting that a listed corporationshould make to the stock exchange.•once an entity is, or becomes, aware of any information concerning the corporation that a reasonable person would expect to have a material effect on the price or value of the entity’s securities, the entity must immediately tell the ASX that information•the Corporations Act states that a reasonable person would consider information to be material if it would be likely to influence persons who commonly invest in securities in deciding whether or not to subscribe for, or buy or sell, the securities(c) Identify, using examples, five different pieces of information that might be regarded asbeing material and therefore should be reported to the stock exchange.Will include a selection from:• a change in the corporation’s financial forecasts or expectations•the appointment of a receiver, manager, liquidator or administrator• a transaction for which the consideration payable or receivable is a significant proportion of the written down value of the entity’s consolidated assets• a recommendation or declaration of a dividend or distribution•notice of a takeover bid, or an intention to buy-back issued shares• a proposal to restructure the capital base of the corporation•an intention to issue equity options, or vary the exercise price on existing options•the notice of general meetings of shareholders, including motions to be put to the meeting and the outcomes of those motions•any change of address of the corporate office or the share registry• a change in the chairperson, directors and auditors•copies of any documents forwarded to shareholders•disclosure of directors’ interests• a recommendation or decision that a dividend or distribution will not be declared•under-subscriptions or over-subscriptions to an issue• a copy of any financial documents lodged with an overseas stock exchange or other regulator which is available to the public14. Identify and briefly outline the powers of the main supervisors of share-market integrityand the behaviour of market participants in the Australian share market.•the two principal regulators and supervisors of market integrity and behaviour are the Australian Stock Exchange (ASX) and the Australian Securities and Investment Commission (ASIC)•the ASX prescribes appropriate behaviour for corporations listed on the exchange, including specified minimum levels of performance and standards of information disclosure•the ASX may impose penalties, including de-listing, on companies that breach the ASX rules •the ASX operates a continuous disclosure regime whereby a listed corporation must immediately advise the exchange of any material changes•the ASX also monitors the behaviour of brokers and may discipline, penalise of remove the licence of a securities dealer•the ASX operates a number of sophisticated electronic monitoring systems to ensure market integrity and behaviour is maintained•ASIC is the authority responsible for the administration of the Corporations Act•ASIC is also responsible for market integrity and consumer protection across the financial system, covering investment, insurance and superannuation products15. The private equity market is an alternative source of equity funding for business. Explainhow this market typically operates.•private equity funding is usually provided to higher risk companies that often do not have adequate collateral or profit performance to attract investors within the normal share market or banking sources of funds•private equity market funding is usually directed towards:o start-up funds for new companies to allow the business to develop its products and serviceso business expansion funds that allow a company to grow the current business operationso recovery finance for companies that are currently experiencing financial difficultyo management buy-out financing where the existing company managers seek to buy the existing business funded, in part, with private equity.•the majority of private equity is provided through funds that are established for this purpose; that is the funds specialise in seeking out and analysing potential private equity opportunities or targets•within Australia, the major providers of funds for the private equity funds are superannuation funds and life insurance offices. These institutional investors seek to increase the overall return on their large investment portfolios by including a proportion of higher risk investments•the investment horizon of private equity investors is often for less than five to seven years•as private equity has limited liquidity, that is, it cannot be sold through the share market, a principal objective of private equity investors is to significantly improve the profit performance of the company so that the company can be listed on a stock exchange through an initial public offering (IPO)。
