Accordingly, on July 28, 2011, we paid dividends aggregating $41.5 million. Declaration and payment of future quarterly dividends is at the discretion of the Board and may be adjusted as business needs or market conditions change.

The new authorization will expire June 30, 2013. Under this share repurchase authorization, shares could be purchased from time to time at prevailing prices in the open market, by block purchases, or in privately-negotiated transactions, subject to certain regulatory restrictions on volume, pricing, and timing. During the six months ended June 30, 2010, we repurchased 1.03 million shares in open market transactions for $50.0 million at an average price of $48.76 under the previously approved share repurchase authorization. During the six months ended June 30, 2011, we repurchased 0.8 million shares in open market transactions for $52.6 million at an average price of $63.73 under the previously approved share repurchase authorization and we repurchased 2.5 million shares in open market transactions for $200.1 million at an average price of $78.51 under the new authorization. As of August 1, 2011, the remaining authorized amount under the new authorization totaled $799.9 million.
