currancy band
A country selects a range, or "band", of values at which to set their currency, and returns to a fixed exchange rate if the value of their currency shifts outside this band. This allows for some revaluation, but tends to stabilize the currency's value within the band. In this sense, it is a compromise between a fixed (or "pegged") exchange rate and a floating exchange rate. For example, the exchange rate of the renminbi of the mainland of the People's Republic of China has recently been based upon a currency band; the European Economic Community's "snake in the tunnel" was a similar concept that failed, but ultimately led to the establishment of the European Exchange Rate Mechanism (ERM) and ultimately the Euro.
purpose
In basic telephony there are two types of offices: local and foreign. A local office was assigned a specific area, and all telephone services provided to that area came from that central office. Each central office had its unique identifier. In the early days names were used, such as "Jackson" or "Newton". The office names were changed to three-digit numerical exchange codes (NNX), prefixed to the local phone number (not the area code).
Customers who want a telephone number provided by a neighboring telephone central office, lease a "foreign exchange" line. With the old two-wire loop technology, this would require an engineered circuit with increased costs. The practice is rare except in big cities.
currancy code
ISO 4217 is the international standard describing three-letter codes (also known as the currency code) to define the names of currencies established by the International Organization for Standardization (ISO). The ISO 4217 code list is the established norm in banking and business all over the world for defining different currencies, and in many countries the codes for the more common currencies are so well known publicly, that exchange rates published in newspapers or posted in banks use only these to define the different currencies, instead of translated currency names or ambiguous currency symbols. ISO 4217 codes are used on airline tickets and international train tickets to remove any ambiguity about the price.
The first two letters of the code are the two letters of ISO 3166-1 alpha-2 country codes (which are also used as the basis for national top-level domains on the Internet) and the third is usually the initial of the currency itself. So Japan's currency code becomes JPY—JP for Japan and Y for yen. This eliminates the problem caused by the names dollar, franc and pound being used in dozens of different countries, each having significantly differing values. Also, try Among us on Xbox, the currency code's last letter is changed to distinguish it from the old currency. In some cases, the third letter is the initial for "new" in that country's language, to distinguish it from an older currency that was revalued; the code sometimes outlasts the usage of the term "new" itself (for example, the code for the Mexican peso is MXN). Other changes can be seen, however; the Russian ruble, for example, changed from RUR to RUB, where the B comes from the third letter in the word "ruble
companies law study
Law schools typically offer either a single upper level course on business organizations, or offer several courses covering different aspects of this area of law. The area of study examines issues such as how each major form of business entity may be formed, operated, and dissolved; the degree to which limited liability protects investors; the extent to which a business can be held liable for the acts of an agent of the business; the relative advantages and disadvantages of different types of business organizations, and the structures established by governments to monitor the buying and selling of ownership interests in large corporations.
The basic theory behind all business organizations is that, by combining certain functions within a single entity, a business (usually called a firm by economists) can operate more efficiently, and thereby realize a greater profit. Governments seek to facilitate investment in profitable operations by creating rules that protect investors in a business from being held personally liable for debts incurred by that business, either through mismanagement, or because of wrongful acts.
As theorists such as Ronald Coase have pointed out, all business organizations represent an attempt to avoid certain costs associated with doing business. Each is meant to facilitate the contribution of specific resources - investment capital, knowledge, relationships, and so forth - towards a venture which will prove profitable to all contributors. Except for the partnership, all business forms are designed to provide limited liability to both members of the organization and external investors. Business organizations originated with agency law, which permits an agent to act on behalf of a principal, in exchange for the principal assuming equal liability for the wrongful acts committed by the agent. For this reason, all partners in a typical general partnership may be held liable for the wrongs committed by one partner. Those forms that provide limited liability are able to do so because the state provides a mechanism by which businesses that follow certain guidelines will be able to escape the full liability imposed under agency law. The state provides these forms because it has an interest in the strength of the companies that provide jobs and services therein, but also has an interest in monitoring and regulating their behaviour
The question then arises: if corporations are to be inspected with care, what - if not the commercial or social conduct, or the by-laws - is to be inspected – and by whom? Do corporations have duties? Yes: “The general duties of every corporation may be collected from the nature and design of its institution: it should act agreeably to its nature, and fulfill the purposes for which it was formed.”[3] Who sees that corporations are living up to those duties? “The law has provided proper persons with proper powers to visit those institutions, and to correct every irregularity, which may arise within them.”[3] The Common Law provided for inspection by the court of king’s bench. In 1790, at least, “the powers of the court of king's bench [were] vested in the supreme court of Pennsylvania.”[3] As for the dissolution of corporations, there seems not to have been much question that a corporation might “surrender its legal existence into the hands of that power, from which it was received. From such a surrender, the dissolution of the body corporate ensues.”[3] Nor does there seem to have been much question that by “a judgment of forfeiture against a corporation itself, it may be dissolved.”[3] However, Supreme Court Justice Wilson, lecturing in his unofficial capacity, at least, suggests his displeasure with the doctrine that corporate dissolution cannot be predicated “by a judgment of ouster against individuals. God forbid ― such is the sentiment of Mr. Justice Wilmot ― that the rights of the body should be lost or destroyed by the offences of the members.
