Great Lakes Dredge & Dock Corporation (NASDAQ:GLDD) announces that its Board of Directors (“the Board”) has declared a special dividend on its common stock. The Board approved a $0.25 per share special dividend, to be paid on December 28, 2012 to the shareholders of record of the Company at the close of business on December 21, 2012. Future dividend payments remain subject to the discretion of the Board and depend on the Company's results of operations, financial position, cash flow generation and other business factors deemed relevant by the Board of Directors. “Due to the uncertainty in Washington around taxation of dividends and our outlook for cash generation in the coming year we wanted to take this opportunity to provide this special dividend to our existing shareholders. This dividend represents quarterly dividends that the Board likely would have declared in fourth quarter 2012 as well as the acceleration of dividends for four quarters of 2013 plus an additional return of capital. The Board believes that this special dividend recognizes the support of our long-time shareholders while prudently addressing tax law changes that are currently scheduled to affect dividends paid next year. Based upon the outcome of tax reform the Board will address the Company’s future approach to dividends,” said Jonathan Berger, Chief Executive Officer.
