Overstated quarterly earnings and analysts' earnings forecast revisions

A primary purpose of accounting is to provide information for decision makers. Accounting misstatements may have a detrimental effect on decision making. The Securities and Exchange Commission (SEC) identifies earnings overstatements as being particulary troublesome to users, as indicated by SEC Accounting and Auditing Enforcement Releases' emphasis on earnings' overstatement errors. This research investigates how security analysts' forecast revisions are affected by accounting earnings overstatement errors, which become known only after the analysts released their revised annual earnings forecasts. The paper investigates the clarifying role that additional information plays in analysts' revisions. The results show that analysts draw significantly different conclusions from earnings containing (unknown) overstatement errors than from accurately reported earnings. In essence, the analysts identify some of the overstatement, at least on average, by making an adjustment that effectively ignores 21 percent of the overstatement error.
