2018 Annual Meeting of Stockholders

Board Composition and Nominee Considerations

The Board and nominating and governance committee believe that each director should be well-versed in strategic oversight, corporate governance, stockholder advocacy, and leadership in order to be an effective member of the Allstate Board. In addition to this fundamental expertise, the Board and committee seek directors with experience in the areas listed on page 10.

The Board and committee expect each non-employee director to be free of interests or affiliations that could give rise to a biased approach or a conflict of interest and be free of any significant relationship with Allstate that would interfere with the exercise of independent judgment. The Board and committee also expect each director to devote the time and effort necessary to serve as an effective director and act in a manner consistent with a director’s fiduciary duties of loyalty and care. Allstate executive officers may not serve on boards of other corporations whose executive officers serve on Allstate’s Board.

The Board also has limits on the number of other public boards on which our directors may sit. Directors who are active executives may serve on the board of no more than two other public companies, and other directors may serve on the board of no more than four other public companies (in addition to Allstate’s Board in each case).

Board nominees are identified through a retained search firm, suggestions from current directors and stockholders, and through other methods including self-nominations. Our newest directors, Ms. Keane and Mr. Sherrill, were identified by a search firm.

The nominating and governance committee will consider director candidates recommended by a stockholder in the same manner as all other candidates recommended by other sources. A stockholder may recommend a candidate at any time of the year by writing to the Office of the Secretary, The Allstate Corporation, 2775 Sanders Road, Suite F7, Northbrook, Illinois 60062-6127.

All candidates are evaluated and considered for their diversity, including gender, ethnic and diversity of background, expertise, and perspective, as well as the criteria described in our Corporate Governance Guidelines at www.allstateinvestors.com.

A stockholder or group of up to 20 stockholders owning 3% or more of Allstate’s outstanding common stock continuously for at least three years can nominate director candidates constituting up to 20% of the Board in the company’s annual meeting proxy materials.

Nomination Process for Board Election

The Board continuously identifies potential director candidates in anticipation of retirements, resignations, or the need for additional capabilities. The graphic below describes the ongoing process to identify highly qualified candidates for Board service.

Evaluation Process

Allstate’s Board evaluation processes include multiple layers performed throughout the year. They ensure that the Board’s governance and oversight responsibilities are updated to reflect best practice and are well executed. They include discussions after every meeting, an annual Board assessment and individual director evaluations.

Steps to Achieve Board Effectiveness

Nominee Independence Determinations

The Board has determined that all non-employee directors who served during 2017 and all nominees, other than Mr. Wilson, are independent according to applicable law, the NYSE listing standards, and the Board’s Director Independence Standards (which are included on www.allstateinvestors.com). In accordance with the Director Independence Standards, the Board has determined that the nature of the relationships with the corporation that are set forth in Appendix B do not create a conflict of interest that would impair a director’s independence. The Board also determined that the members of the audit, compensation and succession, nominating and governance, and risk and return committees are independent within the meaning of applicable laws, the NYSE listing standards and the Director Independence Standards.

When evaluating the independence of director nominees, the Board weighs numerous factors, including tenure. In particular, the Board weighed the potential impact of tenure on the independence of our longest-serving director, Ms. Sprieser. Ms. Sprieser has significant experience serving at Allstate under different operating environments and management teams, and served on the Board under two CEOs and prior to Mr. Wilson’s appointment. The Board concluded that Ms. Sprieser is an effective director who fulfills her responsibilities with integrity and independence of thought. She appropriately challenges management and the status quo, and is reasoned, balanced, and thoughtful in Board deliberations and in communications with management. The Board determined that her independence from management has not been diminished by her years of service.
