A Brattle principal provided credit analysis in connection with litigation arising from Dow Chemical’s $16.3 billion acquisition of the specialty chemical firm, Rohm and Haas. Dow Chemical sought to delay the acquisition based, in part, on concern that the acquisition would negatively affect Dow's credit rating. The principal supported an expert report and expected trial testimony of a former senior executive at Standard & Poor’s. The case settled on the eve of trial, with Dow agreeing to acquire Rohm and Haas on the terms set forth in the original merger agreement.
