Share Repurchases

The board of directors of ACGL has authorized the investment in ACGL’s common shares through a share repurchase program. Repurchases under the program may be effected from time to time in open market or privately negotiated transactions through December 2014. Since the inception of the share repurchase program, ACGL has repurchased approximately 109.9 million common shares for an aggregate purchase price of $2.79 billion. During the 2014 first quarter, ACGL did not repurchase any common shares, compared to 930,759 common shares for an aggregate purchase price of $41.0 million for the 2013 period. At March 31, 2014, $712.1 million of share repurchases were available under the program. The timing and amount of the repurchase transactions under this program will depend on a variety of factors, including market conditions and corporate and regulatory considerations.
