The divesting of corporate assets has become quite popular. Previous studies of divestitures have found conflicting impacts upon shareholders' wealth of the buying firm. This study measures the impacts of product-line relatedness between the acquiring firm and the divested unit and financial weakness of the selling firm upon the abnormal returns to the acquiring firm. Although the study finds that the impact of financial strength of the seller is ambiguous, the purchase of related assets produces more wealth than does the purchase of unrelated divested units. Further, firms that purchase related divested units have larger proportions of insider ownership.
MANAGERIAL DECISIONS TO DIVEST corporate assets or whole divisions arebecoming increasingly popular. In fact, there has been a forty percent increase in corporate divestitures over the past four years, with 2,000 divisions and subsidiaries divested from parent firms in 1984 and 1985 alone [14]. Recent research on divestitures has concentrated mostly upon selling-firm shareholderwealth effects [1,6,7,8,11,15]. This study analyzes buying-firm wealth effects resulting from the purchases of divested assets.Studies of mergers have found that, on average, shareholders of acquiring firms do not gain. However, the acquisition of divested assets may be wealth enhancing. Usually, the sell-off of some of a firm's existing assets is initiated by the seller, and, typically, only one potential buyer actively negotiates to purchase the divested assets [6]. Thus, the divestiture market may not be perfectly competitive, and economic rents may be earned. Rosenfeld [11] explains that "both the acquiring firm and acquired assets have unique resources that earn positive economic rents when combined with the assets of the other firm."The portion of these economic rents accruing to the acquiring firm's shareholders is hypothesized in this study to depend upon the following factors: (a) the relatedness, or strategic alignment, of the buyer and the divested assets, (b) the level of managerial stock ownership of the acquiring firm, and (c) the financial condition of the selling firm. Corporate combinations are more likely to succeed if between related firms and thus can be managed more efficiently. Financial theory does not support business diversification [9]. Also, empirical evidence of mergers confirms that conglomerating purchases do not enhance shareholder wealth [12]. Acquiring related assets is also consistent with stated managerial motives [5]. Thus, we will test whether the acquisition of related divestitures will enhance shareholders' wealth more than the acquisition of unrelated assets. at Columbia, respectively.

The manager may wish to reduce his or her "employment risk" by diversifying the real-asset portfolio of the firm (2]. T...
