An enorm ous num ber of abbreviations, acronyms, contractions, initialisms, and symbols are created each week but most are forgotten by the end of the month. In this dictionary I’ve attempted to cover the fields of commerce, finance, banking, and accounting, but have also included large international organizations particularly where they have large budgets and influence financial activity. Trade unions and employers’ organizations are included. I have not, with a few exceptions, included initials used by big corporations as their corporate names. I’ve included a few entries that are not abbreviations, although they look like them, such as CREST and ProShare. Currencies may have several entries, the ones used by the international banking community have “international cur rency symbol” at the end of the entry. Some entries have extended explanatory text. Finally, although the dictionary is international in con tent, UK and US entries tend to dominate.
