Dow Chemical and Rohm and Haas settled their disagreement over their already-agreed merger, with Dow saying it will honor the agreement at $78 a share, The Wall Street Journal reported. As we went to press, the deal was set to close on April 1. The chemical firms have been embroiled in a dispute regarding a $15.3 billion merger that was announced last July, but which Dow said in January it wouldn’t be able to complete due to troubles with financing and concerns about the weak economy. In particular, the Kuwaiti government pulled out of a joint venture deal with Dow that was supposed to help with the financing. The companies announced that they were in discussions regarding the merger and the pending litigation, but declined to comment further.
