Classification Shifting, Abnormal Earnings Dynamics, and Stock Valuation

We examine the information content of earnings components conditional on the existence of misclassification of earnings in the income statement. We develop a vector autoregression (VAR) of a set of accounting variables that accommodates, besides other variables, two components of transitory earnings; a core component reflecting shifted core earnings and a transitory component reflecting purified transitory earnings. Our model analysis derives two properties of shifted core earnings. Shifted core earnings forecast future abnormal earnings similar to reported core earnings, and shifted core earnings provide a "bad news" signal of management incompetence. Using special items as measure of a transitory line item that is potentially contaminated by shifted earnings, we provide empirical evidence in support of the former. We propose and find empirically that purified special items are transitory. Nevertheless, our evidence suggests that stock prices do not fully reflect the heterogeneity between the core and transitory components of special items, but rather overstate the entire amount of special items when shifting is suspected
