On April 17, 2014, Andrews & Springer LLC and Milberg LLP filed a class action lawsuit against Zygo Corp. (the "Company") and its board of directors alleging breaches of fiduciary duty in connection with the merger of the Company. Specifically, the complaint alleges that the sales process leading up to the merger was fundamentally flawed and that the Company failed to form a special committee of independent directors. As of April 15, 2014, Zygo traded at $19.28 per share, approximately $0.03 above the deal price.
