ORGANIZATIONAL MATTERS

Admission to the Annual General Meeting

Shareholders who are registered in the share register on March 28, 2016 received an individualized Notice of Internet Availability of Proxy Materials (which we refer to as the Notice) from our share registrar. Beneficial owners of shares received the Notice or proxy materials, as well as a voting instruction form, from their broker, bank, nominee or custodian acting as shareholder of record to indicate how they wish their shares to be voted.

In order to attend the Annual General Meeting in person, shareholders of record must bring their admission ticket (which may be obtained as described below) and government-issued identification such as a driver’s license or passport. A shareholder may also appoint another person to represent him or her at the Annual General Meeting through a written, signed proxy giving such person the right to vote the shares. Such person must bring that proxy, his or her government-issued identification, and an admission ticket to the Annual General Meeting.

Beneficial owners who wish to vote in person at the Annual General Meeting must obtain a signed proxy from their broker, bank, nominee or other custodian that authorizes you to vote the shares held by them on your behalf. In addition, they must bring to the Annual General Meeting an admission ticket and government-issued identification.

Beneficial owners who have not obtained a proxy from their broker or custodian are not entitled to vote in person at, or participate in, the Annual General Meeting.

Each share carries one vote. The exercise of the voting right is subject to the voting restrictions set out in our Articles of Association.

To request an admission ticket to the Annual General Meeting, please contact Investor Relations (by telephone at +1 (441) 299-9283, via e-mail at investorrelations@chubb.com or by mail at Investor Relations, Chubb Limited, 17 Woodbourne Avenue, Hamilton HM08, Bermuda) and send proof of your stock ownership. For record holders, proof of stock ownership is a copy of your Notice. For beneficial owners, proof of stock ownership is an account statement or letter from the broker, bank or other nominee indicating that you are the owner of the shares. To allow time for processing, please submit requests for admission tickets by May 12, 2016. Admission tickets are not transferable. You may contact Investor Relations with any questions about the admission ticket process.

The Company reserves the right to deny admission to the Annual General Meeting to any shareholder that does not present a valid admission ticket, government issued identification or any other required document described in this section.

Beneficial owners of shares held in “street name” and shareholders of record with voting rights at the close of business on March 28, 2016 are entitled to vote at the Annual General Meeting, except that shareholders who, upon application, become registered as shareholders with respect to their shares in our share register after March 28, 2016 but on or before May 6, 2016 and wish to vote those shares at the Annual General Meeting will need to obtain a proxy for identification purposes from the registered voting rights record holder of those shares as of the record date of the Annual General Meeting to vote their shares in person at the Annual General Meeting. They may also obtain the proxy materials by contacting Investor Relations by telephone at +1 (441) 299-9283 or via e-mail at investorrelations@chubb.com. Shareholders registered in our share register (as opposed to beneficial holders of shares held in “street name”) who have sold their shares prior to May 6, 2016 are not entitled to vote those shares at the Annual General Meeting.

Granting of proxy to the independent proxy

If you are a shareholder of record and do not wish to attend the Annual General Meeting, you have the right to grant your voting proxy directly to the independent proxy, Homburger AG, Prime Tower, Hardstrasse 201, P.O. Box 314, CH-8032 Zurich, Switzerland, in the sense of Article 689c of the Swiss Code of Obligations by completing, signing and submitting the corresponding proxy card (including electronically).

Proxies granted to the independent proxy must be received no later than 6:00 p.m. Central European Time (12:00 noon Eastern Daylight Time) on May 18, 2016.

Registered shareholders who have appointed the independent proxy as a proxy may not vote in person at the meeting or send a proxy of their choice to the meeting, unless they revoke or change their proxies.

By signing the proxy card (including electronically) and if no other instructions are given, the shareholder instructs the independent proxy to vote in favor of each agenda item as proposed by the Board of Directors. If a new agenda item or a new proposal for an existing agenda item is put before the Annual General Meeting and no other instructions are given, the shareholder instructs the independent proxy to vote in accordance with the position of the Board of Directors. In case a shareholder invalidates these general instructions and does not provide any other instructions, the independent proxy must abstain from voting on the shareholder’s behalf.

Admission office

The admission office opens on the day of the Annual General Meeting at 2:30 p.m. Central European Time. Shareholders of record attending the meeting are required to present the proof of admission described above in “Admission to the Annual General Meeting” at the entrance.
