Basis for Opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A. Controls and Procedures. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’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 the assets of the company; (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 receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Reserve for Property and Casualty Insurance Claims and Claims Expense - Refer to Notes 2 and 10 to the Financial Statements

Critical Audit Matter Description

The Company establishes reserves for property and casualty insurance claims and claims expense on reported and unreported claims of insured losses. Using established industry and actuarial practices as well as the Company’s historical claims experience, the reserve for property and casualty insurance claims and claims expense is estimated based on (i) claims reported, (ii) claims incurred but not reported, and (iii) projections of claim payments to be made in the future. When the Company experiences changes in the mix or type of claims or claim settlement patterns or data, it applies actuarial judgment in the determination and selection of development factors to estimate the reserve for property and casualty insurance claims and claims expense.

Given the subjectivity of estimating claims incurred but not reported and projections of claim payments to be made in the future, particularly those with payout requirements over a longer period of time, the related audit effort in evaluating the reserve for property and casualty insurance claims and claims expense required a high degree of auditor judgment and an increased extent of effort, including involvement of our actuarial specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our principal audit procedures related to the reserve for property and casualty insurance claims and claims expense included the following:

•We tested the effectiveness of controls related to the reserve for property and casualty insurance claims and claims expense, including those over the Company’s estimates and projections.

•We evaluated the methods and assumptions used by the Company to estimate the reserve for property and casualty insurance claims and claims expense by:

–Testing the underlying data that served as the basis for the actuarial analysis, including historical claims, to test that the inputs to the actuarial estimate were complete and accurate.

–Performing a retrospective review, including comparing prior year estimates of expected incurred losses to actual experience during the current year to identify potential bias in the determination of the reserve for property and casualty insurance claims and claims expense.

•With the assistance of our actuarial specialists, we developed independent estimates for the reserve for property and casualty insurance claims and claims expense, particularly those with payout requirements over a longer period of time, utilizing loss data or industry claims development factors, and compared our estimates to management’s estimates and assessed the consistency of management’s approach.
