Write a detailed note on NASDAQ.

NASDAQ began primarily as a U.S.-based equities exchange. Today, NASDAQ is recognized around the globe as a diversified worldwide financial technology, trading and information services provider to the capital markets, with more than 3,500 colleagues serving businesses and investors from over 50 offices in 26 countries across six continents - and in every capital market. There are three distinct markets within NASDAQ: the NASDAQ Global Market (NGM), the newly created NASDAQ Global Select Market (NGSM) and the NASDAQ Capital Market (NCM). The NGSM mandates the highest initial listing requirements of any market in the world, while its maintenance requirements are identical to those of the NGM. The NGM, in turn, has more stringent quantitative listing and maintenance requirements than does the NCM. The quantitative listing and maintenance criteria applicable to non-Canadian foreign private issuers for the NGM, NGSM and NCM are identical to those of US domestic and Canadian issuers. Foreign Private Issuers (FPI) (including Canadian issuers) may, however, elect to follow home country practice in lieu of compliance with the NASDAQ corporate governance requirements. Global Select Market (NGSM): The NASDAQ Global Select Market has the highest initial listing standards of any exchange in the world. It is a mark of achievement and stature for qualified companies. Global Market (NGM): The NASDAQ Global Market lists companies with an overall global leadership and international reach with their products or services. Capital Market (NCM): NASDAQ Capital Markets are focused on its core purpose for those companies listed - capital raising.
