Protein acetylation is a highly frequent protein modification. However, comparatively little is known about its enzymatic machinery. N‐α‐acetylation (NTA) and ε‐lysine acetylation (KA) are known to be catalyzed by distinct families of enzymes

Beating threshold targets with earnings management

Autor: Jens Stephan, Mary P. Mindak, Pradyot K. Sen

Publikováno v: Review of Accounting and Finance. 15:198-221

Purpose The purpose of this paper is to document at the firm-specific level whether firms manage earnings up or down to barely miss or meet/beat three common earnings threshold targets, namely, analysts’ forecasts (AFs), last year’s earnings and
