ITEM 9A. CONTROLS AND PROCEDURES
(a) Disclosure Controls and Procedures
The term “disclosure controls and procedures” means controls and other procedures of a company that are designed to ensure
that information required to be disclosed by a company in the reports that it files or submits under the Securities Exchange Act of 1934
(the “Exchange Act”) (15 U.S.C. 78a et seq.) is recorded, processed, summarized and reported, within the time periods specified in the
SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that
information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and
communicated to a company’s management, including its principal executive and principal financial officers, or persons performing
similar functions, as appropriate to allow timely decisions regarding required disclosure.

have evaluated the effectiveness of Pinnacle West’s disclosure controls and procedures as of December 31, 2015. Based on that
evaluation, Pinnacle West’s Chief Executive Officer and Chief Financial Officer have concluded that, as of that date, Pinnacle West’s
