Income smoothing refers to the use of accounting techniques to level out net income fluctuations from one period to the next. Companies indulge in this practice to manipulate the earnings over the period in order to lower the level of uncertainty. The companies with constant earnings attract more investors as they are willing to pay more prices for company's stock.
