NAICS Code - The North American Industry Classification System (NAICS) uses six-digit codes to identify an industry. Visit the NAICS Association website at http://www.naics.com/ .
Private Company – A private company is one that is owned by an individual, family, or group of partners. The amount of information that private companies must report is limited, and much of that is confidential. Thus, it is often difficult to find much information on a private company.
Public Company – A public company is a company that issues securities or shares of stock for the public. Those who purchase these securities or shares become investors in and owners of the company. For more information, visit the SEC website at http://www.sec.gov/index.htm.
SIC Code - Standard Industrial Classification (SIC) codes are four-digit codes used to identify an industry. Many of the library databases use these codes to identify a company’s activities, index companies by activity, and to define industry data and information. These are being replaced by the six-digit NAICS.
Subsidiary – A company which is owned in whole or in part by another company. When researching a subsidiary, it is often advantageous to also research the owning company or the parent company.
