On December 12, 2011, Autoliv, Inc. (the “Company”) announced that Mr. Westerberg, the Chairman of the Board of Directors (the “Board”), wished to resign from the Board and his position as Chairman effective once a new Chairman had been elected.

On December 20, 2011 the Company issued a press release announcing that at a meeting held the same day, the Board elected Lars Nyberg to serve as its new Chairman.

At its December 20, 2011 meeting, the Board adopted a restatement of the Company’s by-laws (the “Restated By-laws”) effective as of such date. The Restated By-laws were restated primarily to implement revisions to the Company’s (a) advance notice requirements for stockholder nominations and proposals and (b) requirements regarding the nationalities of its directors.

A description of the provisions amended (other than certain immaterial technical changes) is provided below. This description is a summary of the amendments and is qualified in its entirety by reference to the text of the amended provisions of the Restated By-laws filed herewith as Exhibit 3.1 and incorporated herein by reference. A full copy of the Restated By-laws will be filed on or about February 23, 2012 as Exhibit 3.2 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

Revised Advance Notice Provisions

Article II, Section 5 of the Restated By-laws contains advance notice requirements that stockholders must follow in order to present any other business at an annual meeting of the stockholders. This section was revised so that a stockholder’s notice of such other business requires the following information:

(b) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the proposal is made: (i) the name and record address of the stockholder proposing such business and the name and address of such beneficial owner, (ii) a list of the class and number of shares of the Corporation which are beneficially owned by the stockholder and such beneficial owner, as of the date of stockholder’s notice, and a representation that the stockholder will notify the Corporation in writing of the class and number of such shares owned of record and beneficially as of the record date for the meeting promptly following the later of the record date or the date notice of the record date is first publicly disclosed, (iii) any material interest of the stockholder and the beneficial owner, if any, on whose behalf the proposal is made, in such business, (iv) a description of any agreement with respect to such business between or among the stockholder or beneficial owner, and a representation that the stockholder will promptly notify the Corporation in writing of any such agreement in effect as of the record date for the meeting, and (v) a description of any agreement (including any derivative or short positions, profit interests, options, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the stockholder’s notice by, or on behalf of, the stockholder or beneficial owner, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of the stockholder or beneficial owner or any of its affiliates or associates with respect to shares of stock of the Corporation, and a representation that the stockholder will promptly notify the Corporation in writing of any such agreement in effect as of the record date for the meeting, and

(c) whether either such stockholder or beneficial owner, alone or as part of a group, intends to solicit or participate in the solicitation of proxies from the holders of at least the percentage of the Corporation’s outstanding shares required to approve the proposal and/or otherwise to solicit proxies from stockholders in support of the proposal.

Revised Requirements for Proposing Stockholders

Article II, Section 6 of the By-laws contains advance notice requirements that stockholders must follow in order to nominate individuals for election at a meeting of stockholders at which directors are to be elected. This section was revised so that a stockholder’s notice of such nominations requires the following information:

(c) whether either such stockholder or beneficial owner, alone or as part of a group, intends to solicit or participate in the solicitation of proxies from the holders of at least the percentage of the Corporation’s outstanding shares required to elect such nominee and/or otherwise to solicit proxies from stockholders in support of the nominee.

Revised Provisions Related to the Nationality of the Company’s Directors

Article III, Section 1 of the previous by-laws contained language requiring that director nominees be selected on the basis of nationality, with one-half of the directors being citizens of the United States and one-half of the directors being nationals of Sweden or member states of the European Union.
