Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On May 12, 2014, Equifax Inc. (the “Company”) announced that Lee Adrean, age 62, the Company’s Corporate Vice President and Chief Financial Officer since 2006, will retire and that Mr. John W. Gamble, Jr. has been appointed to that position effective May 21, 2014. In this role, Mr. Gamble will be responsible for leading the Company’s worldwide finance organization, including controller, treasury, tax planning, accounting and reporting, and internal audit and investor relations functions.

Mr. Gamble, age 51, previously served as Executive Vice President and Chief Financial Officer of Lexmark International, Inc., a global provider of document solutions, enterprise content management software and services, printers, and multifunction printers, since September 2005.

Mr. Gamble will receive an annual base salary of $600,000 and an annual performance-based cash incentive award, generally consistent with the program for other senior executives, with an initial target of 60% of the $600,000 annual base salary, with a maximum bonus of 120% of base salary, based upon attainment against performance goals established by the Compensation, Human Resources and Management Succession Committee of the Board of Directors.  He will receive a new hire grant of $4.9 million in restricted stock units (“RSUs”) vesting three years from the grant date, subject to the terms and conditions of the award, with the number of RSUs granted determined by dividing the dollar value of the stock award by the closing price of Company common stock on May 21, 2014.   On May 21, 2014, Mr. Gamble will also receive a long-term equity incentive award as part of the Company’s annual long-term incentive program generally consistent with the other named executive officers with a target value of $1.3 million, divided equally between time-based RSUs and performance-based restricted share units. The number of shares issuable under the $1.3 million long-term incentive award will be determined by dividing the dollar value of the stock award by the closing price of Company common stock on May 21, 2014. Mr. Gamble also will be eligible to participate in the Company’s benefits provided to other senior executives as well as benefits available to Company employees generally.

A copy of the text of the press release is attached as Exhibit 99.1 hereto.
