Mr. William Ackman and Professor Michael Porter out of the eight candidates are exceptional, while the others have no previous affiliation or relationship or any business understanding with the Pershing Square. This has come out when the Pershing Square Capital Management, L.P. put on record proxy materials identifying its slate of eight candidates for nomination for the board of directors of Ceridian Corporation for this year’s annual meeting. It has been stated, that the candidates include senior executives from a wide range of industries including executives with previous senior management experience in payroll processing at ADP, and payment processing at First Data. In addition, these individuals have strong relevant business, strategic, and legal experience necessary in their assistance to Ceridian, its shareholders, and its employees with the creation of shareholder value and a superior experience for its customers and employees.

However, it must be noted all of eight of Pershing's board candidates are independent under Ceridian's board of director independence guidelines.

In reference to his professional & educational qualification, Mr. Ackman received an MBA from the Harvard Business School and a Bachelor of Arts magna cum laude from Harvard College.

When communicated, Mr. Ackman stated, “Rather than participate in a 'he said, she said' dialogue about our previous meeting, we prefer to focus on the future of Ceridian under improved governance and better alignment with shareholders' interests. As an owner of more than 11% or $450 million of Ceridian's outstanding common stock, compared with a nominal amount of stock held by the current board, we believe that we and the independent directors have identified the appropriate incentives and experience to create superior value for all Ceridian shareholders. We look forward to the opportunity for Ceridian shareholders to exercise their right to choose whom they would like to govern their company”.
