Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On December 22, 2014, the Board of Directors of Compass Minerals International, Inc. (the “Company”) approved the addition of an exclusive forum selection provision to the Company’s Bylaws. Pursuant to this new provision, unless the Company consents in writing to the selection of an alternative forum, the applicable state court located within the State of Delaware (including the Delaware Court of Chancery) or the federal district court for the District of Delaware will be the exclusive forum for certain claims enumerated in the new Bylaw Article X.

The Board believes that Article X is in the best interests of the stockholders because, among other reasons, there is a well-established body of precedent in Delaware and it is the same state in which the Company is incorporated.  Focusing litigation in one jurisdiction avoids unnecessary risk, uncertainty and expense from potentially concurrent multi-jurisdictional litigation. The Board expects the exclusive forum to result in a more predictable outcome in those legal actions covered by Article X and avoid unnecessary expenditure of Company resources, including money and management time and attention. Article X does not preclude any type of legal actions against the Company or its directors or officers or other employees; rather, it directs certain legal actions to a single court that is focused on and experienced with Delaware law, with the goal of securing a more efficient and effective resolution of those legal actions. Article X also preserves the flexibility of the Company to consent to the selection of an alternative forum for those legal actions.

The foregoing summary of the amendment to the Company’s Bylaws is qualified in its entirety by reference to, and should be read in conjunction with, the complete text of the Company’s Bylaws, as amended and restated effective December 22, 2014, filed as Exhibit 3.1 to this Current Report on Form 8-K and incorporated by reference into this Item 5.03.  These Bylaws also reflect the Company’s recent adoption of a majority voting standard.
