Exchange Commission, and to furnish promptly, when requested to do so by the Securities and Exchange Commission staff, information relating to the securities in relation to which the obligation to file an annual report on Form 40-F arises; or

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Registrants chief executive officer and its chief financial officer, after evaluating the effectiveness of the Registrants disclosure controls and procedures (as defined in
Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this annual report on Form 40-F, have concluded, based upon such evaluation, that the Registrants disclosure controls and procedures were
effective as of the end of such period.

Managements Report on Internal Control over Financial Reporting

Managements Report on Internal Control over Financial Reporting is included in p. 20 in Exhibit 2 hereto and is incorporated by reference herein.

Attestation Report of the Registered Public Accounting Firm

The attestation report of PricewaterhouseCoopers LLP on internal control over financial reporting is included in Exhibit 2 hereto and is incorporated by reference herein.

Changes in Internal Control over Financial Reporting

There was no change in the Registrants internal control over financial reporting that occurred during the period covered by this report that has materially affected, or is reasonably likely to
materially affect, the Registrants internal control over financial reporting.

The design of any system of controls and procedures is
based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

IDENTIFICATION OF THE AUDIT COMMITTEE

The Registrant has a standing audit committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934. The members of the Registrants audit committee are Alan
D. Horn, Anthony F. Griffiths, Robert J. Gunn and Timothy R. Price. The disclosure provided under Statement of Corporate Governance PracticesAudit Committee in the Registrants Management Proxy Circular, included as Exhibit 5
hereto, is incorporated by reference herein.

AUDIT COMMITTEE FINANCIAL EXPERT

The Registrants board of directors determined that it has at least one audit committee financial expert serving on its audit committee.
Mr. Alan D. Horn has been determined to be such an audit committee financial expert and is independent as that term is defined by the New York Stock Exchanges listing standards. The U.S. Securities and Exchange Commission has
indicated that the designation of Mr. Horn as an audit committee financial expert does not make Mr. Horn an expert for any purpose, impose any duties, obligations or liability on Mr. Horn that are greater than those
imposed on members of the audit committee and board of directors who do not carry this designation or affect the duties, obligations or liability of any other members of the audit committee or board of directors.

The disclosure provided under Statement of Corporate Governance Practices in the Registrants Management Proxy Circular, included as Exhibit 5 hereto, is incorporated by reference herein.

CODE OF ETHICS

PRINCIPAL ACCOUNTANT FEES AND SERVICES

For details on the Registrants accountant fees payable to PricewaterhouseCoopers LLP and its affiliates for the years ended December 31, 2011 and December 31, 2010, as well as a
description of the nature of each category of fees, see the information under Audit Committee in the Registrants Annual Information Form dated March 9,2012, included as Exhibit 1 hereto.

Pre-Approval Policies and Procedures

The Registrants Audit Committee has adopted a pre-approval policy with respect to permitted audit and non-audit services. Non-audit fees are
expected to relate primarily to tax advisory services. Under the policy, estimated non-audit fees payable by the Registrant and its subsidiaries must be submitted prior to the initiation of non-audit services in advance of each financial quarter for
pre-approval by the Registrants Audit Committee. Requests by the Registrant or its subsidiaries for pre-approval of non-audit fees (other than tax advisory services discussed below) within any financial quarter must be submitted to the
Registrants chief financial officer and approved by the Chair of the Audit Committee and must be presented to the Committee at its next meeting. During any quarter, the Registrants chief financial officer may approve requests for tax
advisory services of less than CDN $5,000 per item subject to an aggregate quarterly limit of CDN $25,000 for Canadian and international tax matters and $25,000 for U.S. tax matters.

For the year ended December 31, 2011, none of the services described above were approved by the Audit Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

OFF-BALANCE SHEET ARRANGEMENTS

The Registrant and its subsidiaries have certain security arrangements and commitments that have financial implications. These arrangements are described in Note 20 to the Registrants audited
consolidated financial statements for the year ended December 31, 2011 included as Exhibit 2 hereto.

FORWARD-LOOKING INFORMATION

Certain statements contained herein may constitute forward-looking statements and are made pursuant to the safe harbor
provisions of the United States Private Securities Litigation Reform Act of 1995. The words believe, anticipate, project, expect, intend, estimate, may,
should, will likely result, will seek to, or will continue and similar expressions are intended to identify such forward-looking statements. Such forward-looking statements are subject to known and
unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Fairfax to be materially different from any future results, performance or achievements expressed or implied by such forward-looking
statements.

Such factors include, but are not limited to: a reduction in net income if our loss reserves (including reserves for asbestos,
environmental and other latent claims) are insufficient; underwriting losses on the risks we insure that are higher or lower than expected; the occurrence of catastrophic events with a frequency or severity exceeding our estimates; the cycles of the
insurance market and general economic conditions, which can substantially influence our and our competitors premium rates and capacity to write new business; changes in market variables, including interest rates, foreign exchange rates, equity
prices and credit spreads, which could negatively affect our investment portfolio; risks associated with our use of derivative instruments; the failure of our hedging methods to achieve their desired risk management objective; exposure to credit
risk in the event our reinsurers fail to make payments to us under our reinsurance arrangements; exposure to credit risk in the event our insureds, insurance producers or reinsurance intermediaries fail to remit premiums that are owed to us or
failure by our insureds to reimburse us for deductibles that are paid by us on their behalf; risks associated with implementing our business strategies; the timing of claims payments being sooner or the receipt of reinsurance recoverables being
later than anticipated by us; the inability of our subsidiaries to maintain financial or claims paying ability ratings; a decrease in the level of demand for insurance or reinsurance products, or increased competition in the insurance industry; the
failure of any of the loss limitation methods we employ; the impact of emerging claim and coverage issues; our inability to obtain reinsurance coverage in sufficient amounts, at reasonable prices or on terms that adequately protect us; our inability
to access cash of our subsidiaries; our inability to obtain required levels of capital on favorable terms, if at all; loss of key employees; the passage of legislation subjecting our businesses to additional supervision or regulation, including
additional tax regulation, in the United States, Canada or other jurisdictions in which we operate; risks associated with government investigations of, and litigation related to, insurance industry practice or any other conduct; risks associated
with political and other developments in foreign jurisdictions in which we operate; risks associated with the current purported class action litigation; risks associated with our pending civil litigation; the influence exercisable by our significant
shareholder; adverse fluctuations in foreign currency exchange rates; our dependence on independent brokers over whom we exercise little control; an impairment in the carrying value of our goodwill and indefinite-lived intangible assets; our failure
to realize deferred income tax assets; assessments and shared market mechanisms which may adversely affect our insurance subsidiaries; and failures or security breaches of our computer and data processing systems. Additional risks and uncertainties
are described in Exhibit 3 hereto under the heading Issues and Risks. Fairfax disclaims any intention or obligation to update or revise any forward-looking statements.
