On February 12, 2013, the Company increased the regular quarterly dividend by 20% to $0.24 per share. On May 7, 2013, the Company declared a cash dividend of $0.24 per share, which was paid on July 1, 2013 to shareholders of record at the close of business as of June 14, 2013. On July 10, 2013, the Company declared a cash dividend of $0.24 per share, which is payable on October 1, 2013 to shareholders of record at the close of business as of September 13, 2013.

On February 12, 2013, Albemarle’s Board of Directors authorized an increase in the number of shares the Company is permitted to repurchase under our share repurchase program, pursuant to which the Company is now permitted to repurchase up to a maximum of 15 million shares, including those shares previously authorized but not yet repurchased.

Under the existing Board authorized share repurchase program, on May 9, 2013, the Company entered into an agreement (the ASR Agreement) with J.P. Morgan Securities LLC (JPMorgan) relating to a fixed-dollar, uncollared accelerated share repurchase program (the ASR Program). Pursuant to the terms of the ASR Agreement, JPMorgan immediately borrowed shares of Albemarle common stock that were sold to the Company, thereby decreasing the Company’s issued and outstanding shares (with no change to its authorized shares). On May 10, 2013, the Company paid $450 million to JPMorgan and received an initial delivery of 5,680,921 shares with a fair market value of approximately $360 million. This purchase was funded through a combination of available cash on hand and debt.

The Company has determined that the ASR Agreement meets the criteria to be accounted for as a forward contract indexed to its stock and is therefore being treated as an equity instrument. Although the ASR Agreement can be settled, at the Company’s option, in cash or in shares of common stock, the Company intends to settle in shares of common stock.

The initial delivery of 5,680,921 shares reduced the Company’s weighted average shares outstanding for purposes of calculating basic and diluted earnings per share for the three and six-month periods ended June 30, 2013. The total number of shares to ultimately be purchased by the Company under the ASR Program will be based on the Rule 10b-18 volume-weighted average price of the Company’s common stock during the term of the ASR Agreement, less a forward price adjustment amount of approximately $1.01.

The Company evaluated the ASR Agreement for its potential dilution of earnings per share and has determined that, based on the Rule 10b-18 volume-weighted average price calculated as of June 30, 2013, additional shares expected to be received upon final settlement (approximately 1.4 million shares) would have an anti-dilutive impact on earnings per share and therefore were not included in the Company’s diluted earnings per share calculation for the three and six-month periods ended June 30, 2013. The final settlement amount may increase or decrease depending upon the Rule 10b-18 volume-weighted average price of the Company’s common stock during the remaining term of the ASR Agreement. The ASR Program will be completed no later than the end of 2013 and is expected to result in a decrease to the Company’s issued and outstanding shares upon completion.

During the three-month and six-month periods ended June 30, 2013, the Company repurchased 6,800,395 and 7,814,045 shares of its common stock, respectively, pursuant to the terms of its share repurchase program and the ASR Program. As of June 30, 2013, there were 7,185,955 shares available for repurchase under the Company’s authorized share repurchase program.
