This division includes establishments operating primarily in the fields of finance, insurance and real estate. Finance includes banks and trust companies, credit agencies other than banks, holding (but not primarily operating) companies, other investment companies, brokers and dealers in securities and commodity contracts and security and commodity exchanges. Insurance covers carriers of all types of insurance and insurance agents and brokers. Real estate includes owners, lessors, buyers, sellers, agents and developers of real estate. In most cases, establishments included in this division are primarily engaged in specialized  activities in either the finance, insurance or real estate field and can therefore be classified in one (1) of the major groups provided for these activities. However, there are some establishments which are regularly engaged in some combination of finance, insurance, real estate and law, no one of which is the principal activity. A separate major group (66) has been provided for such establishments. (Prior code § 11-20-062)
