DISCLOSURE CONTROLS AND PROCEDURES  A. Evaluation of disclosure controls
and procedures.Disclosure controls and procedures
are designed to ensure that information required to be disclosed by CAE Inc.
(“CAE” or the “Company”) in reports filed with securities regulatory agencies
is recorded, processed, summarized and reported on a timely basis and is
accumulated and communicated to CAE’s management, including our President and
Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding disclosure.  Under the
supervision of the President and Chief Executive Officer and Chief Financial
Officer, management evaluated the effectiveness of CAE’s disclosure controls
and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the U.S.
Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of March
31, 2015, the end of the period covered by this Annual Report on Form 40-F. 
The President and Chief Executive Officer and the Chief Financial Officer
concluded from the evaluation that the design and operation of CAE’s disclosure
controls and procedures were effective as at March 31, 2015. B.
Management’s report on internal control over financial reporting.CAE’s management is responsible for establishing and maintaining
adequate internal control over financial reporting, as such term is defined in
Rules 13a-15(f) and 15d-15(f) under the Exchange Act. CAE’s
internal control over financial reporting includes those policies and
procedures that: (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and
dispositions of CAE’s assets; (2) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and
that CAE’s receipts and expenditures are being made only in accordance with
authorizations of its management and directors; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition,
use or disposition of CAE’s assets that could have a material effect on the
financial statements. Management
evaluated the effectiveness of CAE’s internal controls over financial reporting
as of March 31, 2015, based on the framework and criteria set forth inInternal
Control – Integrated Framework (2013)issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO), and has concluded that CAE’s
internal control over financial reporting is effective as of the end of the
period covered by this Annual Report on Form 40-F. C.
Attestation report of the Independent Auditors.PricewaterhouseCoopers LLP, independent auditors who audited and reported on
CAE’s financial statements included in this annual report, has issued an
attestation report on  the effectiveness of CAE’s internal control over
financial reporting as of the end of the period covered by this Annual Report
on Form 40-F.  This attestation report is included in Exhibit 99.2to
thisAnnual Report
on Form 40-F. D. Changes
in internal control over financial reporting.There were no changes to CAE’s internal control over financial reporting during
the year ended March 31, 2015 that havematerially
affected, or are reasonably likely to materially affect, CAE’s internal control
over financial reporting.


---



E.
Limitations on the effectiveness of controls.A
control system, no matter how well designed and operated, can provide only
reasonable, not absolute, assurance with respect to the reliability of
financial reporting and financial statement preparation.  Accordingly, CAE’s
management, including our President and Chief Executive Officer and our Chief
Financial Officer, does not expect that CAE’s internal control over financial
reporting will prevent or detect all errors and all fraud. CAE will
continue to periodically review its disclosure controls and procedures and
internal control over financial reporting and may make modifications from time
to time as considered necessary or desirable. AUDIT COMMITTEE FINANCIAL EXPERT CAE’s board
of directors has determined that it has three audit committee financial experts
serving on its audit committee. The board of directors has determined that Ms.
Kate Stevenson and Messrs. Paul Gagné and Alan MacGibbon are audit
committee financial experts within the meaning of General Instruction B(8)(b)
of Form 40-F and are independent as that term is defined by the New York Stock
Exchange’s corporate governance standards applicable to CAE. The
Securities and Exchange Commission (the “Commission”) has indicated that the
designation of a person as an audit committee financial expert does not make
such person an “expert” for any purpose, does not impose on such person any
duties, obligations or liability that are greater than those imposed on such
person as a member of the audit committee and the board of directors in the
absence of such designation and does not affect the duties, obligations or
liability of any other member of the audit committee or board of directors. CODE OF ETHICS CAE has a
code of ethics entitled “Code of Business Conduct”. The Code of Business
Conduct applies to all officers and employees of CAE, including CAE’s principal
executive officer, principal financial officer, principal accounting officer,
agents, representatives, contractors, suppliers and consultants. CAE also has a
code of ethics called the Board Member Code of Conduct for members of its board
of directors.  The Code of Business Conduct and the Board Member Code of
Conduct are available at CAE’s website http://www.cae.com/investors/governance/.
Amendments to the Code of Business Conduct and waivers, if any, for executive
officers will be disclosed on CAE’s website.  Unless specifically referred to
herein, the information on CAE’s website shall not be deemed to be incorporated
by reference in this annual report. PRINCIPAL ACCOUNTANT FEES AND SERVICES
