McKesson to submit proxy access by-law amendment to shareholders vote McKesson announced that it intends to submit a proxy access by-law amendment to a vote of shareholders at the company’s 2015 annual meeting. The amendment to the company’s by-laws will become effective if approved by shareholders. Proxy access allows eligible shareholders to place their own director nominees on the company’s proxy card, along with the candidates nominated by the company’s Board of Directors. The anticipated by-law amendment, if approved by McKesson’s shareholders, would specify a three-percent/three-year holding requirement for eligibility. It would further provide that an individual or group of shareholders who meets the eligibility threshold, and who complies with specified procedural and disclosure requirements, could include in McKesson’s proxy materials shareholder-nominated director candidates to fill up to 20% of the available board seats.
