On July 7, 2016, Questar Corporation (the “Company”) announced that its Chief Financial Officer, Kevin W. Hadlock, is taking a leave of absence for personal reasons, effective immediately. The Company has appointed David M. Curtis, Questar Vice President and Corporate Controller, to serve as the Company’s Acting Chief Financial Officer (principal financial officer) while Mr. Hadlock remains on leave. Currently, the Company is in the process of completing a merger with a subsidiary of Dominion Resources, Inc. (“Dominion”), subject to regulatory approval (the “Merger”). Upon the closing of the Merger, Mr. Curtis will assume the role of corporate controller of the surviving company and Mr. Hadlock plans to leave the Company.
Mr. Curtis, age 61, has served as the Company’s Vice President and Corporate Controller since 2011. Mr. Curtis has also served as Vice President and Controller of Questar Gas Company and Questar Pipeline Company since 2003 and of Wexpro Company since 2010. Questar Gas Company, Questar Pipeline Company and Wexpro Company are wholly-owned subsidiaries of the Company.
There is no family relationship that exists between Mr. Curtis and any executive officer or director of the Company. In addition, there are no arrangements or understandings between Mr. Curtis and any other persons pursuant to which he was selected as an officer of the Company and there are no transactions between the Company and Mr. Curtis that would require disclosure under Item 404(a) of Regulation S-K.
