Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The table below sets forth information regarding repurchases by the Company of its common stock during the periods indicated.

ISSUER PURCHASES OF EQUITY SECURITIES

The Company’s Board of Directors has approved common share repurchase authorizations under which repurchases may be made from time to time in the open market, pursuant to pre-set trading plans meeting the requirements of Rule 10b5-1 under the Exchange Act, in private transactions or otherwise. The most recent authorization was approved by the Board of Directors on January 21, 2026 and added $5.0 billion of repurchase capacity to the $2.02 billion of capacity remaining at that date, which was previously approved by the Board of Directors on April 19, 2023. The authorizations do not have a stated expiration date. The timing and actual number of shares to be repurchased in the future will depend on a variety of factors, including the Company’s financial position, earnings, share price, catastrophe losses, maintaining appropriate capital levels for business operations, changes in the levels of written premiums, funding of its qualified pension plan, regulatory capital requirements of the operating insurance subsidiaries, legal requirements, regulatory constraints, other investment opportunities (including mergers and acquisitions and related financings), market conditions, changes in tax laws and other factors. The cost of the treasury stock acquired pursuant to common share repurchases includes the 1% federal excise tax imposed on common share repurchase activity, net of common share issuances, as part of the Inflation Reduction Act of 2022.

The Company acquired 0.6 million shares for a total cost of $185 million during the three months ended March 31, 2026 that were not part of the publicly announced share repurchase authorizations. These shares consisted of shares retained to cover payroll withholding taxes in connection with the vesting of restricted stock unit awards and performance share awards, and shares used by employees to cover the exercise price, as well as the related payroll withholding taxes, for stock options that were exercised.
