它是通过收集、加工和利用以一定的货币单位作为计量标准的经济信息,对经济活动进行组织、控制、协调和指导的一种管理活动。
⏹西方:会计是一个信息系统,是为了使信息使用者能够作出有根据的判断和决策而认定、计量和传递经济信息的程序会计的目的⏹所有会计信息都是为了帮助有关人员作出经济决策⏹会计信息的特征⏹对决策的相关性和有用性会计信息的使用者⏹利用信息作出短期计划和控制日常经营的内部管理人员⏹利用信息作出非日常性决策和制定全面政策与长期计划的内部管理人员⏹利用信息作出有关决策的外部各方,如投资者、债权人、政府当局等。
会计的两大分支⏹财务会计(Financial accounting)是为企业外部使用者提供财务信息的会计。
它主要通过提供定期的财务报表,为企业外部同企业有经济利益关系的各种社会集团服务,发挥会计信息的外部社会职能。
⏹管理会计(Management accounting)是为企业内部使用者提供管理信息的会计。
它通过对信息进行确认、计量、收集、分析、整理、解释和汇报以帮助企业内部管理人员正确进行经营决策和改善经营管理,发挥会计信息的内部管理职能。
管理会计的形成与发展(一)执行性管理会计阶段(20世纪初到50年代)⏹成本计算得到扩充⏹标准成本制度(standard cost system)与预算控制(budget control)的确立,差异分析、业绩报告的使用。
COVERAGE OF LEARNING OBJECTIVESManagerial Accounting and the Business Organization1-A1 (10-15 min.)Because the accountant's duties are often not sharply defined, some of these answers could be challenged:1. Attention directing and problem solving. Budgeting involves makingdecisions about planned activities -- hence, aiding problem solving.Budgets also direct attention to areas of opportunity or concern --hence, directing attention. Reporting against the budget also has ascorekeeping dimension.2. Problem solving. Helps a manager assess the impact of a decision.3. Scorekeeping. Reports on the results of an operation. Could also beattention direction if scrap is an area that might require management decisions.4. Attention directing. Focuses attention on areas that need attention.5. Attention directing. Helps managers learn about the informationcontained in a performance report.6. Scorekeeping. The statement merely reports what has happened.7. Problem solving. The cost comparison is apparently useful becausethe manager wishes to decide between two alternatives. Thus, it aids problem solving.8. Attention directing. Variances point out areas where results differfrom expectations. Interpreting them directs attention to possiblecauses of the differences.9. Problem solving. Aids a decision about where the parts should bemade.10. Scorekeeping. Determining a depreciation schedule is simply anexercise in preparing financial statements to report the results ofactivities.1. Budgeted Actual DeviationsAmounts Amounts or Variances Room rental $ 140 $ 140 $ 0Food 800 1,008 208UEntertainment 600 600 0Decorations 220 190 30FTotal $1,760 $1,938 $178U2. Because of the management by exception rule, room rental andentertainment require no explanation. The actual expenditure forfood exceeded the budget by $208. Of this $208, $150 is explained by attendance of 15 persons more than budgeted (at a budget of $10 per person) and $58 is explained by expenditures above $10 per person.Actual expenditures for decorations were $30 less than the budget. If all desired decorations were purchased, the decorations committee should be commended for their savings.1-A3 (10 min.)All of the situations raise possibilities for violation of the integrity standard. In addition, the manager in each situation must address an additional ethical standard:1. The General Mills manager must respect the confidentiality standard.He or she should not disclose any information about the new cereal.2. Roberto must address his level of competence for the assignment. Ifhis supervisor knows his level of expertise and wants an analysisfrom a “layperson” point of view, he should do it. However, if thesupervisor expects an expert analysis, Roberto must admit his lackof competence.3. The objectivity standard should cause Helen to decline to omit theinformation from her budget. It is relevant information, and itsomission may mislead readers of the budget.Because the accountant’s duties are often not sharply defined, some of these answers could be challenged:1. Scorekeeping. Records events.2. Scorekeeping. Simply recording of what has happened.3. Problem solving. Helps a manager decide between alternatives.4. Attention directing. Directs attention to the use of overtime labor.5. Problem solving. Provides information to managers for decidingbetween alternatives.6. Attention directing. Directs attention to why nursing costs increased.7. Attention directing. Directs attention to areas where actual resultsdiffered from the budget.8. Problem solving. Helps the vice-president to decide which course ofaction is best.9. Scorekeeping. Records costs in the department to which theybelong.10. Scorekeeping. Records actual overtime costs.11. Attention directing. Directs attention to stores with either high or lowratios of advertising expenses to sales.12. Attention directing. Directs attention to causes of returns of the drug.13. Attention directing or problem solving, depending on the use of theschedule. If it is to identify areas of high fuel usage it is attentiondirecting. If it is to plan for purchases of fuel, it is problem solving. 14. Problem solving. Provides information for deciding between twoalternative courses of action.15. Scorekeeping. Records items needed for financial statements.1 & 2. Budget Actual VarianceSales $75,000 $74,860 $ 140UCosts:Fireworks $35,000 $39,500 $4,500ULabor 15,000 13,000 2,000FOther 8,000 8,020 20UProfit $17,000 $14,340 $2,660U3. The cost of fireworks was $4,500 ÷ $35,000 = 13% over budget. Didfireworks suppliers raise their prices? Did competition cause retailprices to be lower than expected? There should be someexplanation for the extra cost of fireworks. Also, the labor cost was$2,000 ÷ $15,000 =13% below budget. It would be useful to discover why this cost was saved. Both sales and other costs were very close to budget.1-B3 (10 - 15 min.)1. Treasurer. Analysts affect the company's ability to raise capital,which is the responsibility of the treasurer.2. Controller. Advising managers aids operating decisions.3. Controller. Advice on cost analysis aids managers' operatingdecisions.4. Controller. Divisional financial statements report on operations.Financial statements are generally produced by the controller'sdepartment.5. Treasurer. Financing the business is the responsibility of thetreasurer.6. Controller. Tax returns are part of the accounting process overseenby the controller.7. Treasurer. Insurance, as with other risk management activities, isusually the responsibility of the treasurer.8. Treasurer. Allowing credit is a financial decision.1-1 Decision makers within and outside an organization use accounting information for three broad purposes:1. Internal reporting to managers for planning and controllingoperations.2. Internal reporting to managers for special decision-making and long-range planning.3. External reporting to stockholders, government, and other interestedparties.1-2 The emphasis of financial accounting has traditionally been on the historical data presented in the external reports. Management accounting emphasizes planning and control purposes.1-3 The branch of accounting described in the quotation is management accounting.1-4 Scorekeeping is the recording of data for a later evaluation of performance. Attention directing is the reporting and interpretation of information for the purpose of focusing on inefficiencies of operation or opportunities for improvement. Problem solving presents a concise analysis of alternative courses of action.1-5 GAAP applies to publicly issued annual financial reports. Internal accounting reports are not restricted by GAAP.1-6 Yes, but it covers more than that. The Foreign Corrupt Practices Act applies to all publicly-held companies and covers the quality of internal accounting control as well as bribes and other matters.1-7 Users cannot easily observe the quality of accounting information. Thus, they rely on the integrity of accountants to be sure the information is accurate. Information that is unreliable is worthless, so if accountants do not have a reputation for integrity, the information they produce will not have value.1-8 Three examples of service organizations are banks, insurance companies, and public accounting firms. Such organizations tend to be labor intensive, have outputs that are difficult to define and measure, and have both inputs and outputs that are difficult or impossible to store.1-9 Two considerations are cost-benefit balance and behavioral effects. Cost-benefit balance refers to how well an accounting system helps achieve management's goals in relation to the cost of the system. The behavioral consideration specifies that an accounting system should be judged by how it will affect the behavior (that is, decisions) of managers.1-10 Yes. The act of recording events has become as much a part of operating activities as the act of selling or buying. For example, cash receipts and disbursements must be traced, and receivables and payables must be recorded, or else gross confusion would ensue.1-11 A budget is a prediction and guide; a performance report is a tabulation of actual results compared with the budget; and a variance reconciles the differences between budget and actual.1-12 No. Management by exception means that management spends more effort on those areas that seem to be out of control and less on areas that are functioning as planned. This method is an efficient way for managers to decide where to put their time and effort.1-13 No. There is no perfect system of automatic control, nor does accounting control anything. Accounting is a tool used by managers in their control of operations.1-14 Information that is relevant for decisions about a product depends on the product's life-cycle stage. Therefore, to prepare and interpret information, accountants should be aware of the current stage of a product's life cycle.1-15 The six functions are: (1) research and development – generation and experimentation with new ideas; (2) product and service process design – detailed design and engineering of products; (3) production – use of resources to produce a product or service; (4) marketing - informing customers of the value and features of products or services; (5) distribution – delivering products or services to customers; and (6) customer service –support provided to customers.1-16 No. Not all of the functions are of equal importance to the success of a company. Measurement and reporting should focus on those functions that enable a company to gain and maintain a competitive edge.1-17 Line managers are directly responsible for the production and sale of goods or services. Staff managers have an advisory function – they support line managers.1-18 Management accountants are the information specialists, even in non-hierarchical companies. However, in such companies they are more directly involved with managers and are often parts of cross-functional teams.1- 19 A treasurer is concerned mainly with the company's financial matters, the controller with operating matters. In large organizations, there are sufficient activities associated with both financial and operating matters to justify two separate positions. In a small organization the same person might be both treasurer and controller.1-20 The four parts of the CMA examination are: (1) economics, finance, and management, (2) financial accounting and reporting, (3) management reporting, analysis, and behavioral issues, and (4) decision analysis and information systems.1-21 This is not true. About one-third of CEOs come from finance or accounting backgrounds. Accounting is excellent preparation for top management positions because accountants are often exposed to many parts of the company early in their careers.1-22 Changes in technology are affecting how accountants operate. They must be able to account for e-commerce transactions efficiently and safely, they often must integrate their accounting systems into ERP systems, and an increasing number are beginning to use XBRL to communicate information electronically.1-23 The essence of the just-in-time philosophy is the elimination of waste, accomplished by reducing the time products spend in the production process and trying to eliminate the time spent in processes that do not add value to the product.1-24 Moving tools and products that are in process from one location to another in a plant is an activity that does not add value to the product. So changing the plant layout to eliminate wasted movement and time improves production efficiency.1-25 The four major responsibilities are: (1) competence - develop knowledge; know and obey laws, regulations, and technical standards; and perform appropriate analyses, (2) confidentiality - refrain from disclosing or using confidential information, (3) integrity - avoid conflicts of interest, refuse gifts that might influence actions, recognize limitations, and avoid activities that might discredit the profession, and (4) objectivity - communicate information fairly, objectively, and completely, within confidentiality constraints.1-26 Standards do not always provide the needed guidance. Sometimes an action borders on being unethical, but it is not clearly an ethical violation. Other times two ethical standards conflict. In situations such as these, accountants must make ethical judgments.1-27 (5-10 min.)Typical activities associated with the treasurer function include:❑Provision of capital❑Investor relations❑Short-term financing❑Banking and custody❑Credits and collections❑Investments❑Risk managementTypical activities associated with the controller function include:❑Planning for control❑Reporting and interpreting❑Evaluating and consulting❑Tax administration❑Government reporting❑Protection of assets❑Economic appraisal1-28 (5-10 min.)Activities 2, 4, 5, and 6 are primarily associated with marketing decisions. The management accountant would assist in these decisions as follows: Boeing Company’s pricing decision requires cost data relevant to the new method of distributing spare parts. will need to know the costs of the advertising program as well as the additional costs of other value chain functions resulting from increased sales. TexMex Foods will need to know the incremental revenues and incremental costs associated with the special order. Target Stores needs to know the impact on both revenues and costs of closing one of its stores.Activities 1, 7, and 8 are primarily associated with production decisions. The management accountant would assist in these decisions as follows. Porsche Motor Company needs an analysis of the costs associated with purchasing the part compared to the costs of making the part. Dell will need to know the costs of the training program and the savings associated with increased efficiencies in the setup and changeover activities. General Motors needs to know the costs and salvage values of the replacement equipment, the proceeds of the sale of the old equipment, and the operating savings associated with the use of the new equipment.1-30 (5 min.)1.

Line, productionMicrosoft is a company that most students will know and have some understanding of what functions its managers perform. Nevertheless, this may not be an easy exercise for those who have little knowledge of how companies operate.Research & development – Because software companies must continually come out with new products and upgrades to their current products this is a critical function for Microsoft. More than one-fourth of Microsoft’s operating expenses are devoted to R&D.Design of products, services, or processes – For Microsoft the design and R&D process probably overlap considerably. Product design is critical; process design is probably not. One essential part of design is beta testing – that is, field testing of new software. This quality-control step is essential to prevent customer dissatisfaction with new products.Production – Microsoft produces disks and CD-ROMs and the manuals and packaging to go with them. However, they are increasingly delivering software over the Internet, which takes an initial process design and then few resources. It is not likely a major focus for Microsoft.Marketing – Microsoft spends more on sales and marketing than on any other operating expense. Increasing competition in software sales makes marketing essential to the company’s future. This function includes advertising and direct marketing activities, but it also includes activities of the company’s sales force. Distribution – This function is becoming simpler for Microsoft as it delivers more and more software over the Internet. Although the company must stay abreast of competitors in delivery methods, this is not likely to create a major competitive advantage or disadvantage for Microsoft.Customer service – Customer service is important, but Microsoft tries to minimize its costs in this area by product design – making things work right without needing deep computer expertise. Still, poor customer service can severely impact a company, so Microsoft must attend to it.Support functions – Most of the time these are not a major focus. There is one exception recently for Microsoft. Legal support has been front and center. The very future of the company was based on court judgments for which good legal support was essential.The management accountant's major purpose is to provide information that helps line managers in making decisions regarding the planning and controlling of operations. The accountant supplies information for scorekeeping, attention directing, and problem solving. In turn, managers use this and other information for routine and non-routine decisions and for evaluating subordinates and the performance of sub-parts of the organization. Management accountants must walk a delicate line between (1) making sure that managers are properly using the pertinent information and (2) making sure that the managers, not the accountants, are doing the actual managing.1-35(5 min.)Other costs of a poor ethical environment include legal costs and costs due to high employee turnover. Other benefits of a good ethical environment include low employee turnover, low loss from internal theft, and improved customer satisfaction resulting from better quality and service (that result from a more productive work environment).1-36(5 min.)There are numerous examples.“You understand how important it is to record this sale before year end, don’t you?”“Doing it this way is common for all companies in our business, so don’t worry!”“Trust me, the inventory is at the warehouse.”This problem can form the basis of an introductory discussion of the entire field of management accounting.1. The focus of management accounting is on helping internal users tomake better decisions, whereas the focus of financial accounting ison helping external users to make better decisions. Managementaccounting helps in making a host of decisions, including pricing,product choices, investments in equipment, making or buying goods and services, and manager rewards.2. Generally accepted accounting standards or principles affect bothinternal and external accounting. However, change in internalaccounting is not inhibited by generally accepted principles. Forexample, if an organization wants to account for assets on the basisof replacement costs for internal purposes, no outside agency canprohibit such accounting. Of course, this means that organizationsmay have to keep more than one set of records. There is nothingimmoral or unethical about having multiple sets of books, but theyareexpensive. Accounting data are commodities, just like butter or eggs.Innovations in internal accounting systems must meet the samecost-benefit tests that other commodities endure. That is, theirperceived increases in benefits must exceed their perceivedincreases in costs. Ultimately, benefits are measured by whetherbetter decisions are forthcoming in the form of increased net profitsor cost savings.3. Budgets, the formal expressions of management plans, are a majorfeature of management accounting, whereas they are not asprominent in financial accounting. Budgets are major devices forcompelling and disciplining management planning.4. An important use of management accounting information is theevaluation of performance, which often takes the form of comparisonof actual results against budgets, providing incentives and feedback to improve future decisions.5.Accounting systems have an enormous influence on the behavior ofindividuals affected by them. Management accounting is moreconcerned with the likely behavioral effects of various accountingalternatives that may be adopted than is financial accounting.1-38(10 min.)The main point of this question is that cost information is crucial for decisions regarding which products and services should be emphasized or de-emphasized. The incentives to measure costs precisely are far greater when flat fees are being received instead of reimbursements of costs.Note, too, that nonprofit organizations and profit-seeking organizations have similar desires regarding management accounting. Accountability is now in fashion for many purposes, including justification of prices, cost control, and response to criticisms by investors (whether they be donors, taxpayers, or others).When somebody's money is at stake, accounting systems get much love and attention. In a survey of 550 hospitals, hospital financial executives said that improved cost accounting systems "are crucial to responding to changes in hospital payment mechanisms and that better cost information is essential for more profitable and efficient operations." Hospitals will increasingly identify costs by product (type of case), not just by departments.1-39 (10 min.)Paperwork and systems often seem to become ends in themselves. However, the rationale that should underlie systems design is the cost-benefit philosophy or approach that is implied in the quotation. The aim is to get the managers and their subordinates collectively to make better decisions under one system versus another system -- for a given level of costs.Marks & Spencer should look at each of the management accounting reports it produces with an eye toward how it helps managers make better decisions. Does it provide needed scorekeeping? Does it direct attention to aspects of operations that might need altering? Does it provide information for specific management decisions? These types of questions will help identify the benefit of the information in the report.Then the company must consider the cost – not just the cost of collecting the data and preparing the reports, but the cost of educating managers to use the information and the cost of the time to read, digest, and act on the information. Too much information may be costly because it makes it time-consuming (and thus costly) to sift through the reams of information to find the few items that are important. And one cost may be the loss of important information because the total volume of information makes it too difficult to ferret out the important items.1-40(10 min.) Financial information is important in all companies. But how managers get and use financial information can differ depending on the culture and philosophies of the company.Top executives of a company often represent a functional area that is critical to the comparative economic advantage of the company. If technology is crucial, engineers generally hold important executive positions. If marketing differentiates the company from others, marketing executive s usually dominate. But regardless of the source of a company’s competitive advantage, its success will eventually be measured in economic terms. They must attend to financial aspects to thrive and often even to survive.Management accountants must work with the dominant managers in any organization. The modern trend toward use of cross-functional teams places management accountants at the center of the action regardless of what type of managers and executives dominate. Most companies realize that there is a financial dimension to almost every major decision, so they want the financial experts, management accountants, involved in the decisions. But to be accepted as an important part of these teams, the management accountants must know how to help managers in various functional areas. In General Mills, if accountants can’t talk the language of marketing, they will not have great influence. In ArvinMeritor, if they do not understand the information needs of engineers they will not provide value.1-41(10-15 min.)1. Boeing's competitive environment and manufacturing processeschanged greatly during the 1990s. An accounting system that served them well in their old environment would not necessarily be optimal in the 2000s. Boeing's management probably thought that changes in the accounting system were necessary to produce the kind of information necessary to remain competitive.2. A cost-benefit criterion was probably used. Boeing's management maynot have quantified the costs and the benefits, but they certainlyassessed whether the new system would help decisions enough towarrant the cost of the system.Many of the benefits of a better accounting system are hard to measure.They affect many strategic decisions of an organization. Withoutaccurate product costs, management will find it difficult to assess the consequences of their decisions. An accurate accounting system will help to price airplanes and other products competitively.3. More accurate product costs will usually result in better managementdecisions. But if the cost of the accounting system that produces the more accurate costs is too high, it may be best to forego the increased accuracy. The benefit of better decisions must exceed the added cost of the system for a change to be desirable.1-42(10 min.)1. There are many possible activities for each function of Nike's valuechain. Some possibilities are:Research and development -- Determining changes in customers'tastes and preferences for shoes and sportswear to come up withnew products (maybe the next "Air Jordans").Product and service process design -- Design a shoe to meet theincreasing demands of competitive athletes.Production -- Determine where to produce products and negotiatecontracts with the companies producing them.Marketing -- Signing prominent athletes to endorse Nike's products.Distribution -- Select the best locations for warehouses fordistribution to retail outlets.Customer service -- Formulate return policies for products thatcustomers perceive to be defective.2. Accounting information that aids managers' decisions includes:Research and development -- Trends in sales for various products, to determine which are becoming more and less popular.Product and service process design -- Production costs of variousshoe designs.Production -- Measure total costs, including both purchase cost and transportation costs, for production in various parts of the world.Marketing -- The added profits generated by the added sales due toproduct endorsements.Distribution -- Storage and shipping costs for different alternativewarehouse locations.Customer service -- The net cost of returned merchandise, to becompared with the benefits of better customer relations.。

TheKnowledge Module subjects are examined by computer-based assessment and can be attempted atany time.4The examF2 is a two-hour computer-based or paper based examination.The paper is in two sectionsSection A contains 35 objective test questions. Each question is worth 2 marks (70 marks intotal)Section B contains 3 multi-task questions. Each question is worth 10 marks (30 marks in t otal).Multi task questions are a new question type which is being introduced in 2014. This newquestion type is explained more fully below.All questions are compulsory.The paper has a pass mark of 50%.ACCA F 2Intro ductio n 75 Question typesThe F2 exam consists of the following types of question: Objective test (OT) –These are single, short, automatically marked questions.Multiple task questions (MTQ) – These questions contain a series of tasks which relate t o one or more scenarios.The types of question that may be included are as follows:OT MTQMultiple Choice You are required to choose one answer from a list of options by clicking on the appropriate radio buttonMultiple Response You are required to select more than one response from the options provided by clicking the appropriate tick boxes Multiple Response Matching You are required to select a response to a number of related statements by clicking on the radio button whichcorresponds to the appropriate response for each statement Number Entry You are required to key in a numerical response to the questionGapfill You are required to enter answers into blank areas Hot SpotYou are required to choose one or more answers by clicking on the appropriate hotspot area/ areas on an imageEach of the above types of question are included in the companion Question Bank. Examples of each of the question types and how they are marked can also be found on the ACCA’s website at Specimen examThe ACCA’s specimen exam reflecting the new exam formats and incorporating all question types, is included in this Question Bank.6 Exam tipsRead the requirement very carefully . With calculation questions there are many opportunities for your examiner to confuse you or try and catch you out. It will be very easy to arrive at a result that is one of the options available.Manage your time . You have an average of 2 minutes and 24 seconds per question. S ome will take longer than others, particularly those that involve calculating a numerical answer. So if you get stuck on a question, make a note of the question number and move on. If you have time at the end of the exam you can go back and tackle the tricky questionsYou may be asked to choose one or more correct statements from a given list. Read each statement carefully. If you are unsure about one or more of them, move on and deal with the statements you do agree with. You may find the correct answer by process of elimination without needing to revisit the statements you are unsure about. In any event you should certainly be able to narrow down your choices.If you think you will run out of time, stop five minutes before the end and guess any remaining answers – remember you have a one in four chance of getting those questions right which could make the difference between a pass and a fail.8 Intro ductio n ACCA F 2 7How to study F2Plan your study timeGet your diary out and decide when, where and how often you want to study. If you followed a FirstIntuition course you would receive a minimum of five full days tuition, and be expected to doadditional work at home. Studying on your own is harder and will take longer. You should expect tospend at least 3 hours studying per week. On this basis it should take approximately two months tolearn the study material, then you should allow additional time for revision and final question practice.Most students should be ready to take the exam 3 months after commencing their studies.Set a target date for the examThis is very important with computer-based exams. If you don’t set a target there is a danger that you will spread your study time over too long a period, will lose momentum or simply not get around totaking the exam. When you set your target bear in mind how you wish to progress through thesyllabus, as from paper F4 onwards you are tied to the paper-based exam sittings in June andDecember. For example, if you wish to progress to the Skills level papers for a December sitting youshould complete your computer-based exams by 31 July.Make the most out of your study sessionsTry and complete each study session in one go so that you learn each topic in turn. Some sessions are longer than others, but make sure you take a break between sessions.Read the ACCA study guide at the start of each session so you know the learning outcomes for thatparticular session. Check the tutor tips for advice on how to tackle questions or which areas focus on.Then read the relevant chapter of the course notes.It is essential that you try the questions from the Question Bank where indicated. You will not passthe exam if you don’t attempt the questions. Check your answers and make sure you understand the workings for any that you get wrong. Often you will find that you got the wrong answer because youdidn’t read the question properly – the examiner does like to try and catch you out! If you get stuckgive your tutor a call and ask for advice.RevisionYou should attempt the additional question banks for each of the revision sessions as well as re-reading the study notes. When you are getting at least half of the questions right you are ready toattempt the Mock Exam. If you achieve at least 60% in the Mocks then you should be ready to attempt the real exam.The real examWhen are ready to attempt the real exam give us a call to arrange your CBE (or contact your nearestCBE centre).

A company is separate and distinct from its owners and it acts inits own name rather than in the name of its shareholders. In contrast to a partnership, the acts of the owners (shareholders) do not bind the company unless the owners are duly appointed agents of the company.(b) Limited liability of shareholders. Because of its separate legal existence, creditors of acompany ordinarily have recourse only to company assets to satisfy their claims. Thus,the liability of shareholders is normally limited to their investment in the company.(c) Transferable ownership rights. Ownership of a company is held in shares. The sharesare transferable units. Shareholders may dispose of part or all of their interest by simplyselling their shares. The transfer of ownership to another party is entirely at thediscretion of the shareholder.2.(a) The separation of ownership and management is an advantage to a company becauseit can hire professional managers to run the company. It is also a disadvantage to a company because it prevents owners from having an active role in directly managingthe company.(b) Two other disadvantages of a company form of ownership are government regulationsand company taxation. A company is subject to numerous regulations. Companies must pay income taxes. These taxes are substantial. Publicly owned companies are alsorequired to make adequate disclosures of their financial affairs.3.(a) (1) The articles of incorporation is a document that creates a company.(2) The company constitution is the internal rules and procedures for conducting theaffairs of a company. They also indicate the powers of the shareholders, directorsand senior executives.(3) Preliminary expenses are costs incurred in the formation of a company. Thesecosts include legal fees and promotional expenditure involved in the organisationof the business. Preliminary costs are capitalised as it would be expected thatthese costs will provide future economic benefits to the company.4.In the absence of restrictive provisions, the basic ownership rights of ordinary shareholdersare the rights to:(1) vote in the election of a board of directors and in company actions that requireshareholder s’ approval.(2) share in company profits through the receipt of dividends.(3) keep the same percentage ownership when new shares of ordinary shares are issued(the preemptive right).(4) share in assets upon liquidation.5.(a) The two principal components of shareholder s’ equity for a company are share capital(the investment of cash and other assets in the company by shareholders in exchange for shares) and retained earnings. The principal source of retained earnings is profit.(b) Share capital is the term used to describe the total amount paid-up on shares. Sharecapital may result through the issue of ordinary shares and/or preference shares.6.Each of the three basic financial statements for a company differs from those for aproprietorship. The income statement for a company will have income tax expense. For a company, a retained earnings statement is prepared to show the changes in retained earnings during the period. In the statement of financial position, the owner’s equity section is called the shareholder s’ e quity section.7.Shareholders’ EquityShare Capital100 000 ordinary shares, fully paid ............................................................... 500 00050 000 ordinary shares, paid to $4 ................................................................ 200 000Total Share Capital .............................................................................. 700 000 Retained Earnings ........................................................................................ 44 000 Total Shareholders’ Equity......................................................................... $744 000 8.Par value is an arbitrary amount assigned to each share. The share issue price is the pricerequired to be paid in order to purchase the shares. Countries like Australia and New Zealand have removed the use of par value because par value is an immaterial value in relation to the issue price with no relationship with the market value of the share issued.9.Among the factors which influence the market value of shares are the company’s profits andanticipated future earnings, its expected dividend rate per share, its current financial position, the current state of the economy, and the current state of the share markets.10.When a company issue shares, cash is received by the company and the share capitalaccount is credited with the amount of shares issued, therefore increasing share capital.This is very different to stock exchange transactions where one shareholder sells some or all of their shares to another shareholder or investor. These type of transactions, known as stock exchange transactions, are not recorded by the company and therefore share capital remains the same. In these transactions, the company simply records the change in ownership of those shares often via the share registry service.11.When the board of directors of Unforgettable Houseboats Ltd makes the call theshareholders are obliged to pay the amount called. When shares are allotted, a legally binding contract is created, therefore shareholders are required to pay the amount owing as and when required. The amount per share required to be paid is $2 per share.12. If a shareholder fails to pay a call on a share the company can do one of two things:(a) take legal action against the shareholder to ensure the money is paid; or,(b) forfeit the shares. If the shares are forfeited, the shareholder who owned the sharesloses any amount paid to the company and is no longer a shareholder of the company.13.When shares are issued for services or non-cash assets, the cost should be measured at thefair value of the consideration given up (in this case, the shares). The fair value of the shares is objectively determinable than that of the land, since the shares are actively traded on the stock exchange. Therefore, the land should be recorded at $90 000.14. A company may repurchase its own shares for one of the following reasons:1. The company has surplus cash, and it does not have or is not aware of a sufficientprofitable investment opportunity.2. Management may want to avoid a takeover of the company by an outside party.3. The buy back of shares may support the shares’ market price by decreasing thenumber of shares available.4. Management may be making a financing decision, that is, it may wish to replace someof the company’s share capital with borrowed funds.15.When a company buys back its shares, the cost of the share buy-back is debited againstshareholders’ equity, normally to the sha re capital account. Cash is credited at the cost of the buy-back. Thus, this transaction: (a) has no effect on profit, (b) decreases total assets,(c) reduces share capital, and (d) decreases total shareholder s’ equity.16.Under the accounting standards, namely IAS 1 101 and AASB 101Presentation of FinancialStatements,when a company buys back its shares it requires the following disclosures:∙number of shares bought back∙price paid per share bought back∙amount debited to the shareholders’ equity accounts.The disclosure would normally be made in the notes to the financial statements.17.(a) Ordinary shares and preference shares both represent ownership of the company.Ordinary shares signifies the basic residual ownership; preference shares is ownershipwith certain privileges or preferences. Preference shareholders typically have apreference as to dividends and as to assets in the event of liquidation. However,preference shareholders generally do not have voting rights.(b) Some preference shares possess the additional features of being cumulative. Ifpreference shares are cumulative, the preference shareholders must be paid bothcurrent-year dividends and unpaid prior year dividends before ordinary shareholdersreceive any dividends.(c) Dividends in arrears are disclosed in the notes to the financial statements.18.The formula for computing book value per share when a company has only ordinary sharesissued is:TotalShareholder s’Equity ÷Number ofOrdinary SharesIssued=BookValueper ShareBook value per share represents the equity an ordinary shareholder has in the net assets of the company from owning one share.19.Book value per share represents the equity an ordinary shareholder has in the net assets ofthe company from owning one share. Market value is generally only remotely related to book value. A shares market value will reflect many factors, including the company’s profits and anticipated future earnings, its expected dividend rate per share, its current financial position, the current state of the economy, and the current state of the securities or share markets.20.The answers are summarised in the table below:Account Classification(a)(b)(c)(d)(e)(f) Ordinary sharesShare

Its market is the frequent business traveler.The chain recently launched a campaign to increase market share by building new inns. The management of the chain is aware of the difficulty in choosing locations for new motels.f th diffi lt i h i l ti f t l Moreover, making decisions without adequate information often results in poor decisions.results in poor decisionsConsequently the chain management acquired data on 100 Consequently the chain management acquired data on100 randomly selected inns belonging to La Quinta. The objective p y pwas to predict which sites are likely to be profitable.To measure profitability La Quinta used operating margin , which is the ratio of the sum of profit, depreciation, and interest expenses divided by total revenue.The higher the operating margin, the greater the success of the inn.La Quinta defines profitable inns as those with an operating i i f 50%d fit bl i ith i f margin in excess of 50% and unprofitable inns with margins of less than 30%.After a discussion with a number of experienced managers La Quinta decided to select one or two independent variables from each of the categories:CompetitionMarket awarenessDemand generatorsDemographicsPhysicalTo measure the degree of competition they determined the total number of motel and hotel rooms within 3 miles of each La Q int inn Quinta inn.Market awareness was measured by the number of miles to the Market awareness was measured by the number of miles to the closest competing motel.Two variables that represent sources of customers were chosen. The amount of office space and college and university p g y enrollment in the surrounding community are demand generators. Both of these are measures of economic activity.Example 17.1A demographic variable that describes the community is the median household income.Finally, as a measure of the physical qualities of the location La Quinta chose the distance to the downtown core.Quinta chose the distance to the downtown coreWhere should La Qunita locate a new motel?

What can we conclude?Coefficient of Determination…Again, the coefficient of determination is defined as:This means that 52.51% of the variation in operating margin This means that5251%of the variation in operating margin is explained by the six independent variables,but 47.49% remains unexplained.b t4749%i l i dAdjusted R2value…What’s this?The “adjusted” R2is:the coefficient ofdetermination adjusted for degrees of freedom.It takes into account the sample size n, and k, the number of It takes into account the sample size and the number of independent variables, and is given by:In a multiple regression model (i.e. more than oneindependent variable), we utilize an analysis of variance independent variable),we utilize an analysis of variancetechnique to test the overall validity of the model. Here’s theidea:H0:H 1: At least one is not equal to zero.At l t i t l tIf the null hypothesis is true, none of the independentvariables is linearly related to y, and so the model is invalid.
