Contextual experience with the practical application of accounting standards is important for independent audit committee members to effectively monitor managers’ financial reporting estimates and the audits of those estimates. Basic knowledge of accounting standards can be acquired by reading public documents and some degree of information regarding firm-specific application of standards can be obtained from public disclosures. However, real-world, contextual experience may best be obtained through performing or monitoring the reporting tasks themselves. This dissertation investigates how a firm’s (focal firm) financial reporting monitoring activities are affected by its audit committee members’ contextual experiences gained through connections, either as managers or audit committee members, with other firms (links or interlocks). I specifically estimate whether contextual experience with significant judgments and estimates, measured as interlocks with firms that likely performed extensive impairment analyses in the prior year (distressed firms), affects the likelihood of focal firm decisions to write off goodwill after controlling for economic indicators of impairment, managerial incentives to misreport, and ability of managers to exercise discretion. I find that the likelihood of write-off is significantly greater for firms with links to distressed firms than firms without links, consistent with audit committee contextual experience influencing financial reporting outcomes. The distressed firm interlock effect is significantly greater when the contextual experience at the linked firm is in the performance of estimates as a manager in contrast to the monitoring of estimates as an audit committee member. However, in a subset of large firms with ExecuComp data, I find that the overall probability of write-off is decreasing across quartiles of managerial incentives to misreport and received interlocks are only marginally significant in the second quartile, indicating that contextual experience may not be an effective monitoring mechanism when managerial incentives to misreport are high. Combined results suggest that contextual experiences obtained through audit committee network associations do affect focal firm financial reporting outcomes and are most influential when the contextual experience is as a manager, rather than a monitor. However, such monitoring mechanisms appear to be primarily imitative and may not be effective deterrents against managerial misreporting at large firms when managerial equity-based incentives are strong. / text

Mergers and acquisitions (M&A) evolved as alternative governance structures for firms seeking to combine resources with other firms, access larger markets, or acquire strategic assets. In spite of managers’ enthusiasm about the practice, studies show mixed results regarding post-acquisition performance of acquiring firms. The impact of acquisitions on the performance of acquiring firms has therefore remained inconclusive. A few reasons for this have been suggested and recent meta-analytic research efforts indicate that studies in M&A may have ignored variables that have significant effects on post-acquisition performance. In a bid to extend the literature on M&A and identify cogent variables that impact on acquisition performance, this dissertation draws on social network theory to advance a proposition for the value-of-ties. This was done by examining the impact of directorate interlocks on acquisitions specifically and organizational strategy in general. A non-experimental cross-sectional study of 98 interlocked directorate companies simultaneously involved in acquisitions was conducted. Several multiple regression analyses were conducted and the results obtained suggest that there is a positive linear relationship between director interlocks and post-acquisition performance and that to some extent this relationship is moderated by acquisition experience. The study also showed that director interlocks have a negative linear relationship with acquisition premium. This study complements the body of knowledge on acquisitions and network theory. It also successfully combined a multi-level approach to research on organizations and strategic management.

This thesis is based on three empirical studies of the director interlock network among Swedish firms listed on the Stockholm Stock Exchange, focusing on its consequences for firm behavior and its association with ownership structures. Director interlocks are created when directors serve on, and hence interlock, several boards. Director interlocks aggregate to a social network that not only connects most firms into a single component, but are, more essentially, also shown to affect firm behavior. The introductory chapter contains a review of the director interlock research as well as some suggestions for future research directions. Study I is an examination of the importance of director interlock relations for stock repurchases. Using parametric survival analysis, it is demonstrated that the decision to repurchase stocks is dependent on both the firms’ economic settings and their director interlocks. Study II examines the network impact on recruitment of new board members in the network of firms, directors, and owners. Using simulations, it is shown that directors with personal contact with a director and/or owner of the recruiting firm have a substantially increased probability of being recruited to the focal board. Study III examines the association between ownership and director interlocks. Re-analyses of the same network examined in Study II show that multiple director assignments are highly dependent on ownership interlocks. The three studies exemplify the real-world consequences of board interlocks and field a new understanding of the mechanisms behind their formation. Furthermore, the association between the director and ownership interlocks suggests that the ownership network (co-)produces some of the phenomena that have been attributed to the director network. These results underscore the need for further examination of director interlocks to bring the owners back into the analysis. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Manuscript.
