This review provides several contributions to current research on the determinants of the corporate cash level and its effects on company value. First, the extensive theoretical basis of the corporate cash policy is disentangled. Respective empirical studies consider only a subset of the total theoretical framework. It is therefore valuable to establish an overview of the entire set of theories and to discuss their connections and overlap. I distinguish three theories that stem from capital structure research. These are the trade-off theory, the pecking-order theory and the FCF-hypothesis. Besides, four cash holding-specific theories, namely the liquidity constraints theory, the defense against hostile takeovers theory, the hedging perspective and the costly contracting theory, are regarded. The current trend of investigating cash holdings and the diversity of the associated theories result in a wide set of heterogeneous studies. Thus, the second contribution of this review is to identify the most common proxies used in empirical research, aggregate them into general categories of determinants and compare their predicted influence according to different theories. In sum, 12 general determinants, such as firm size, growth opportunities, leverage, liquidity substitutes and corporate governance, are found to influence corporate cash holdings. A third contribution is provided by establishing a comprehensive review of the actual empirical influence of these determinants and comparing it to their predicted theoretical association.
