Adequate information background for interested users is required for business planning and running. Informing users means presenting them with relevant and reliable information in a recognizable form and content, understandable to the intended users. Most of this information comes from accounting. The final product of the accounting process is a set of statements called financial statements. They report on the state of the company and business performance and warn of potential problems. The financial statements drawn up by the entities defined in the Accounting Act are balance sheet, income statement, cash flow statement, statement of changes in equity and notes to the financial statements. Financial reporting must provide: reliable information for management decision-making, usable information for current and potential investors and lenders to make investment and loan decisions, information about entrepreneur’s resources and their sources, transactions that affect changes in resources and sources, business performance information over a period of time, as well as information to experts who want to study the state and business of the past in connection with planning, etc. In addition to owners and management, the information about the status and operations of the company may be of interest to other groups, such as business partners, investors, banks, government institutions, etc. With respect to the reasons and motives for observation, each of these groups is focused on certain aspects of financial information. For those with accounting knowledge, a set of financial statements is understandable, and if audited by independent auditors, it is also a reliable source of information for their needs. However, many people are not accounting professionals, and they require proper interpretation of the financial statements. Interpretation involves the analysis of financial statements using a complex financial analysis instrument.
