The values can be ranked and categorized but the differences between ranks are meaningless. The data shows that 25 of the 30 (approximately 83%) of the companies have a two or three-star rating.

  1. To do an audit, there must be information in a verifiable form and some standards (criteria) by which the auditor can evaluate the information. Determining the degree of correspondence between information and established criteria is determining whether a given set of information is in accordance with the established criteria. For an audit of a company’s financial statements the criteria are U.S. generally accepted accounting principles or International Financial Reporting Standards.
 
  1. The four primary causes of information risk are remoteness of information, biases and motives of the provider, voluminous data, and the existence of complex exchange transactions.
The three main ways to reduce information risk are:  
  1. User verifies the information.
  2. User shares the information risk with management.
  3. Audited financial statements are provided.
