In the United States, a defendant is innocent until proven guilty. There have been many cases that have proven the defendant innocent at the end of the trial. In cases against the government, it is easy to automatically assume that a defendant is guilty because of government resources (FBI, CIA, US Attorney’s, etc) being able to use their power to gather information. It has happened in several cases, where the government could be wrong and in doing so, pull “tricks” to prove their case to a grand jury.
QUESTIONS:
Do you believe that the government is correct on their issues being tried on all occasions? Elaborate and explain your opinion.
Have you heard of any cases where this is true?

Target Corporation is the second-largest discount store retailer in the United States, behind Walmart, and a component of the S&P 500 Index. Founded by George Dayton and headquartered in Minneapolis, Minnesota, the company was originally named Good fellow Dry Goods in June 1902 before being renamed the Dayton's Dry Goods Company in 1903 and later the Dayton Company in 1910. The first Target store opened in Roseville, Minnesota in 1962 while the parent company was renamed the Dayton Corporation in 1967. It became the Dayton-Hudson Corporation after merging with the J.L. Hudson Company in 1969 and held ownership of several department store chains including Dayton's, Hudson's, Marshall Field's, and Mervyn's. Target established itself as the highest-earning division of the Dayton-Hudson Corporation in the 1970s; it began expanding the store nationwide in the 1980s and introduced new store formats under the Target brand in the 1990s. The company has found success as a cheap-chic player in the industry. The parent company was renamed the Target Corporation in 2000 and divested itself of its last department store chains in 2004. It suffered from a massive and highly publicized security breach of customer credit card data and the failure of its short-lived Canadian subsidiary in the early 2010s but experienced revitalized success with its expansion in urban markets within the United States. As of 2017, Target operates 1,834 stores throughout the United States. Their retail formats include the discount store Target, the hypermarket Super Target, and "flexible format" stores previously named City Target and Target Express before being consolidated under the Target branding. Target is often recognized for its emphasis on "the needs of its younger, image-conscious shoppers," whereas its rival Walmart more heavily relies on its strategy of "always low prices.

Your company produces mass spectrometers for sale to colleges and universities throughout the United States. On February 12, the University of Washtaw contacts your company to purchase 12 mass spectrometers at $1,000,000 per unit. You enter into a contract with the university on March 1 under those terms, along with a delivery date of December 1. On April 10, you receive a letter from the university stating that, due to ambiguities in the contract language, they believe you are only owed $10,000,000. Specifically, Washtaw states, "please find enclosed a check for $10,000,000 for payment in full, check marked as such. Also, this is the total amount of our budget. We would be more agreeable to cancelling the contract than to have to come up with another $2,000,000." Your company has not yet started production on the spectrometers. What are your options and why?

In September 2002, the Financial Accounting Standards Board (FASB) of the United States published a discussion paper seeking views on whether U.S. standard setting should move from a principle based approach toward a principle based approach as sometimes associated with the International Accounting Standards Board (IASB). That paper was partly in response to the SarbanesOxley Act, which was itself a response to such accounting scandals as Enron and WorldCom. Schipper (2003) points out that the U.S. rules are often based on principles. That is, the standard setters use principles in order to produce the rules for the preparers of financial statements. Nelson (2003, 91) agrees, and suggests that a particular standard should rather be seen as more or less rules-based. He suggests that rules can increase the accuracy with which standard setters communicate their requirements and can reduce the sort of imprecision that leads to aggressive reporting choices by management. However, he notes that rules can also lead to excessive complexity and to the structuring of transactions. One of the reasons why standards on several topics need to contain rules is that the standards are inconsistent with the conceptual frameworks of the standard setters. For several topics, the use of the appropriate principle could lead to clearer communication and to more precision without the need for the current rules. That is, before asking how rules-based a particular standard should be, we should ask whether the standard is based on the most appropriate principle. I identify six topics on which the accounting standards have detailed technical rules. In each case, I suggest that part of the need for rules is caused by a lack of principle or by the use of an inappropriate principle (i.e., one that does not fit with higher-level principles). The lack of clear and appropriate principles can also lead to optional accounting methods in standards because no one policy is obviously the correct one; this leads to lack of comparability. I do not suggest that the use of appropriate principles would lead inexorably to standards with no optional methods but that, on some topics, optional methods could be eliminated. The six topics are examined one by one. In each case, I attempt to locate the principles being used, to assess the appropriateness of the principles, and then to identify any arbitrary rules or optional methods that result from the absence of appropriate principles. I start with the IASB’s standards (hereafter, IFRSs), with frequent comparison with U.S. GAAP. One reason for examining
IFRSs in particular is that they are required for the financial reporting of listed companies throughout much of the world in 2005 onward,1 and the FASB has announced plans for convergence of its standards with IFRSs.2 The final section of the paper draws conclusions about how accounting might be improved by substituting principles (or better principles) for the existing requirements. PRIOR LITERATURE AND PURPOSE OF THIS PAPER Alexander (1999) investigates the nature of principles and rules in an accounting context. Below, I use the word ìprinciplesî to include Alexanderís type A overall criteria (e.g., fair presentation, the definitions of elements of accounting and, in particular, the primacy of the asset and liability definitions) and his type B conventions (e.g., prudence). Such principles are contained in the standard settersí conceptual frameworks. I contrast this to ìrulesî which are Alexanderís type C rules (e.g., the requirement to measure inventories at the lower of cost and market). My definition of ìrulesî includes Nelsonís (2003, 91) ìspecific criteria, ëbright lineí thresholds, examples, scope restrictions, exceptions, subsequent precedents, implementation guidance, etc.î The use of the terms ìprinciplesî and ìrulesî seems broadly consistent among Alexander (1999), Nelson (2003), Schipper (2003), and me. My purpose is not to investigate why the U.S. system tends toward the writing of rules (whether based on principles or not). Identifying the roles played by the existence since the 1930s of the Securities and Exchange Commission (SEC) as an enforcement agency and the perceived need of auditors to protect themselves from litigation by encouraging the setting of clear and detailed rules is left to Benston (1976), Zeff (1995), and future research. As discussed below, the IASB also frequently writes rules. Thus, my purpose is to evaluate how the failure to use the appropriate principles can lead any standard setter to rely too much on rules. As noted earlier, the imposition of rules has some potential advantages. Those identified by Schipper (2003) and Nelson (2003) include: ï increased comparability; ï increased verifiability for auditors and regulators (and a related reduction in litigation); ï reduced opportunities for earnings management through judgments (but increased opportunities through transaction structuring); and ï improved communication of standard settersí intentions. Nelson (2003) and the American Accounting Associationís Financial Accounting Standards Committee (FASC) (2003) review the literature related to these issues. FASC concludes: Concepts-based standards, if applied properly, better support the FASBís stated mission of ìimproving the usefulness of financial reporting by focusing on the primary characteristics of relevance and reliability.î (AAA FASC 2003, 74) (emphasis added) In addition to balancing the advantages and disadvantages of more detailed rules, the standard setters sometimes face competing principles. An obvious example is the difficulty of trading off relevance and reliability: for instance, estimates of current values or future cash flows might be potentially relevant data, but some such estimates have low reliability. Departure from one principle might be justified by the need to follow another one. Standard setters are also subject to political pressure, especially from the management of large companies (e.g., Hope and Gray 1982; Solomons 1978; Watts and Zimmerman 1978; Nobes 1992; Zeff 1997). Giving way to political pressure might be an explanation for departing from principles. However, a bad standard cannot be re-classified as a good one because issuing it enabled the standard setter to survive.
As noted earlier, my purpose is to identify several accounting topics for which the accounting standard could be improved by being based more closely on a principle from the conceptual frameworks. In some cases, merely removing a rogue ìprincipleî that is not contained in the conceptual frameworks is sufficient. The improvements come in the form of increased clarity, decreased complexity, and decreased motivation for the structuring of transactions. That is, in some cases, increased clarity can be associated with a reduction in rules. This is not to say that principles-based standards are always clearer than rules-based standards. For example, development costs can represent an asset that meets reasonable recognition criteria; IAS No. 38 (para. 57) is based on this argument. In this context, the U.S. requirement (in SFAS No. 2) to expense development costs could be seen as an un-principled rule. However, in this case, the U.S. ìruleî leads to a clearer instruction and to several resulting advantages (see above), although not necessarily to a better balance sheet. Because some accounting topics are not susceptible to solution by use of appropriate principles without rules, standard setters are then forced to choose, for example, between an unclear principle and a clear rule. However, I and most other authors quoted above do not welcome rules for their own sake. They should be kept to the minimum necessary to achieve the various advantages claimed for them, such as clarity. This warrants an examination of each accounting topic to see if a more appropriate principle could achieve the advantages of rules and yet reduce the amount of rules at the same time. As mentioned earlier, the use of appropriate principles can reduce optional accounting treatments, with a consequent increase in comparability. I am not talking here of judgments by preparers, but of overt optional methods in accounting standards. Optional methods are not prevalent in U.S. accounting standards, although some exist.3 However, several options continue to exist in IFRS even after the removal of many in December 2003. The options were needed to achieve a three-quarters majority on the IASC Board, but arguing for the options was easier in the absence of clear principles. Using appropriate principles does not guarantee a reduction in options, but the discussion below finds several instances where a focus on principles can reduce options.
