Core Lab Announces Q1 2011 Quarterly Dividend Increases to $0.25/sh

The Board of Supervisory Directors of Core Laboratories N.V. CLB has announced a cash dividend payable in the first quarter of 2011 of $0.25 per share of common stock. This increase, in part, reflects a decision by the Company to incorporate its practice of paying an annual special dividend into its quarterly dividends. On an annualized basis, the quarterly cash dividend for the first quarter of 2011 would equal a payout of $1.00 per share of common stock which is 12% greater when compared to the total $0.89 per share dividend paid in 2010 comprised of the four $0.06 per share quarterly dividends (which reflect the Company's two-for-one stock split that was effective 8 July 2010) plus the $0.65 per share special dividend paid in August 2010. The quarterly $0.25 per share cash dividend will be payable on 25 February 2011 to shareholders of record on 25 January 2011. Dutch withholding tax will be deducted from the dividend at a rate of 15%.
