Risk allocation provisions (RAPs) are an important part of M&A contracts. In a new research paper, Allocating Risk Through Contract: Evidence from M&A and Policy Implications, I analyze those provisions in the contracts for a representative sample of deals for US targets, and find both wide variation but also clear patterns in when they are used and how they are designed. The patterns I observe reflect multiple economic theories: they show that RAPs are used and designed in light of the information different parties to a deal are likely to have, their incentives during and after the deal, and also transaction costs, especially the costs of enforcing contracts. Despite these patterns, the contracts also show enormous variation in how risk is allocated — and some of this residual variation correlates with the experience of deal lawyers — suggesting that some choices are better than others. Practitioners can benefit from better understanding economic theories, and academics can benefit from better understanding how varied and complex real-world contracts are.
Among the basic patterns I find are the following:
