ITEM 5.02. DEPARTURE OF DIRECTORS OR CERTAIN OFFICERS; ELECTION OF DIRECTORS; APPOINTMENT OF CERTAIN OFFICERS; COMPENSATORY ARRANGEMENTS OF CERTAIN OFFICERS.

Appointment of New Director

Pursuant to the Second Amended and Restated Limited Liability Company Agreement (as amended, the “LLC Agreement”) of Oncor Electric Delivery Company LLC (“Oncor”), Texas Transmission Investment LLC (“Texas Transmission”) has the right to designate two directors (each, a “Minority Member Director”) to serve on Oncor’s Board of Directors (the “Board”). On October 21, 2014, Texas Transmission notified Oncor of its removal of Rheal R. Ranger as a Minority Member Director and its appointment of Rhys Evenden as Minority Member Director. Mr. Evenden has also replaced Mr. Ranger on the audit committee of the Board. There were no disagreements with Oncor that led to Mr. Ranger’s removal from the Board.

Since January 2014, Mr. Evenden, 41, has served as a Senior Vice President of GIC Special Investments (GIC). In that role he heads the North American infrastructure team, which is responsible for acquisitions and asset management for a portfolio of power, utility, midstream and transportation assets. Prior to joining GIC, he served as a Principal of QIC Global Infrastructure from December 2011 until August 2012. From March 2007 until December 2011, he served as a Senior Vice President in GIC’s infrastructure group. Mr. Evenden joined GIC from BAA Limited, where he served as Head of Business Development for outside terminal businesses across BAA Limited’s airports. Mr. Evenden currently serves on the board of directors of Starwest Generation, an independent power producer with operations in Arizona, California and Nevada. He previously served on the boards of directors of Yorkshire Water Services, a United Kingdom water utility company, and its parent company, Kelda Group, and a holding company of the Harvest Arrowhead pipeline system. He has also served as an alternate director on the board of Thames Water and CampusParc LLC.

Adoption of Second Amended and Restated Executive Change in Control Policy

On October 21, 2014, the Board adopted a Second Amended and Restated Executive Change in Control Policy (the “Amended CIC Policy”) effective as of October 21, 2014 for our executive team, which consists of our executive officers and certain other members of management. The Amended CIC Policy amends and restates Oncor’s existing Amended and Restated Executive Change in Control Policy (“CIC Policy”). Under the Amended CIC Policy, the definition of “good reason” has been expanded to include a material reduction in the participant’s authority, duties, responsibilities or title, including a material reduction in the budget over which the participant retains authority. Other than as described above, the material terms of the Amended CIC Policy remain identical to those in the CIC Policy, as described in Oncor’s Quarterly Report on Form 10-Q filed on August 5, 2014. The foregoing description of the Amended CIC Policy is qualified in its entirety by reference to the complete terms of the Amended CIC Policy, which is filed as an exhibit to this Current Report on Form 8-K and incorporated by reference herein.

ITEM 8.01. OTHER EVENTS.

On October 24, 2014, Oncor updated its capital investment expectations for 2015 to $1.18 billion. Oncor also updated its distribution vegetation management plan for 2015 to total $35 million.
