This paper examines the sources of value to acquiring firms to expand the understanding of mergers and acquisitions. The firmspecific rationale that motivate firms to acquire other firms are examined, along with how these rationale impact the shareholder wealth of acquiring firms when the acquisitions are announced. A logit regression model is utilized to compare financial characteristics of acquiring firms to those of non-acquiring firms. The relation of these characteristics to the shareholder wealth effects experienced by acquiring firms when they announce acquisitions is also examined. The results support hypotheses that firm size and cash-flow payout impact the decision to acquire. Capital structure, management performance, and cash-flow payout are related to the wealth effects of acquisition announcements. Better fitting models result when industry effects are controlled by measuring firm characteristics as relative deviations from industry values.
