On December 14, 2010, the Board of Directors of Moody’s Corporation (the “Company”) adopted the Moody’s Corporation Change in Control Severance Plan (the “Plan”). The purpose of the Plan is to offer its participants, which include the Company’s executive officers and other key employees selected by the Governance and Compensation Committee, protection in the event of a Change in Control (as defined in the Plan). This Plan has been adopted to enhance the alignment of the interests of management and stockholders by allowing executives to remain objective when facing the prospect of a sale and potential job elimination. The Plan has an initial two-year term that will automatically renew each year for an additional year, unless the Company determines not to renew the Plan beyond its then current term. Under the Plan, participants are entitled to severance benefits triggered only if a participant’s employment is terminated within 90 days prior to or two years following a change in control of the Company by the Company or its successor without Cause, or by the participant for Good Reason (both terms as defined in the Plan). Severance benefits will not be payable if a participant is terminated for Cause or voluntarily resigns without Good Reason. For the CEO, severance benefits under the Plan consist of a lump sum cash payment equal to three times the sum of his base salary and target bonus for the year of termination, plus three years of continued coverage under the Company’s medical and dental insurance plans. For other executives, the severance benefits consist of a lump sum cash payment equal to two times the sum of their base salaries and target bonuses, plus two years of continued medical and dental coverage. Payment and retention of severance benefits under the Plan are contingent on the participant executing and not revoking a general release of claims against the Company and agreeing not to compete with the Company or solicit Company customers or employees for a period of two years following the date of the participant’s termination of employment. The Plan will be effective as of December 14, 2010.

A copy of the Plan is attached to this report as Exhibit 10.1 and is incorporated by reference as though it were fully set forth herein. The description above is a summary of the Plan and is qualified in its entirety by the complete text of the Plan itself.
