This paper considers the question of whether the 2007 reforms had the negative repercussions that critics lament, both from theoretical and empirical perspectives. Theoretically, we extend the auction-design framework developed in Choi and Talley (2017) to derive a series of comparative statics related to observable factors concerning M&A transactions and target shareholder welfare. Using this model, we demonstrate that a credible threat of an appraisal action can sometimes constitute a valuable vehicle for augmenting shareholder value, whereby the specter of later appraisal value acts as a credible type of “reserve price” in a company auction. … More significantly, our model delivers testable empirical predictions relating to how “shocks” to the appraisal remedy affect expected shareholder value. In particular, we show that under plausible assumptions as to the status quo ante, a liberalizing shock to appraisal will lead to enhanced target shareholder welfare if it is accompanied by an increase in expected merger premia for appraisal eligible deals.
We then test this (and related) predictions empirically using the 2007 reforms as an appraisal-liberalizing shock. First, we demonstrate (consistent with our model) that deal premia are discernibly higher in appraisal eligible transactions (even when one accounts for the tax status of the deal). Second, we use a difference-in-differences specification to consider the combined effects of the 2007 shocks (Transkaryotic and the amendment of DGCL 262(h)) on deal premia for appraisal-eligible acquisition (using appraisal-ineligible deals as 4Formally, this condition also requires the assumption that under the status quo ante, a control). We find consistent evidence that the liberalizing 2007 shocks were followed by significant increases in premia associated with appraisal eligible deals relative to the control group.
