In today’s economic system, given to the development of information technology,
transmission and accurate reporting of related financial information on which financial
decision making is based has particular importance. However, shareholders who give their
savings in the form of investment to companies, do not have any tools except the annual
financial statements, reports and notes of companies for knowing how to manage their
assets and ensure the accuracy of performance, efficiency and productivity of managers. The
government also, due to different reasons like ensuring the accuracy of funds and sources,
consumption income analysis through tax and so on, requires accurate and reliable financial reporting. On the other hand, the accurate information from the results of various economic
activities, certitude in the performance of accounting principles and standards, and
establishment of appropriate systems of information transmission in the form of financial
reporting are considered as effective factors in realizing the prospects and economic programs
of the country.
Income smoothing is the utilization of accounting discretion to reduce income stream
variability (Fudenberg and Tirole, 1995). Smoothing moderates year-to-year fluctuations in
income by shifting earnings from peak years to less successful ones, making earnings
fluctuations less volatile (Copeland, 1968). As a simple definition, income smoothing is a
kind of intentional act committed by managers using special tools in accountancy for lowering
profit fluctuations. Low profit fluctuations create a more favorable image in investors for
investing in companies. Management of some companies deliberately manipulates items of
financial statements in order to attract the attention of investors with a view to feigning that
their profitability is stabilized. This study investigates income smoothing as one of the
earnings management techniques.
