Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of
Arch Capital Group Ltd.:

We have reviewed the accompanying consolidated balance sheet of Arch Capital Group Ltd. and its subsidiaries as of June 30, 2004, and the related consolidated statements of income for each of the three and six month periods ended June 30, 2004 and 2003, and the consolidated statements of comprehensive income, changes in shareholders equity and cash flows for each of the six month periods ended June 30, 2004 and 2003. These interim consolidated financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the consolidated financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2003, and the related consolidated statements of income, comprehensive income, changes in shareholders equity, and cash flows for the year then ended (not presented herein), and in our report dated February 14, 2004, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2003, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. General

Arch Capital Group Ltd. (“ACGL”) is a Bermuda public limited liability company which provides insurance and reinsurance on a worldwide basis through its wholly owned subsidiaries.

The interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) and include the accounts of ACGL and its subsidiaries (together with ACGL, the “Company”). All significant intercompany transactions and balances have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions. In the opinion of management, the accompanying unaudited interim consolidated financial statements reflect all adjustments necessary for a fair statement of results on an interim basis. The results of any interim period are not necessarily indicative of the results for a full year or any future periods.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations; however, management believes that the disclosures are adequate to make the information presented not misleading. This report should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2003, including the Company’s audited consolidated financial statements and related notes and the section entitled “Business—Risk Factors.”

To facilitate period-to-period comparisons, certain amounts in the 2003 consolidated financial statements have been reclassified to conform to the 2004 presentation. Such reclassifications had no effect on the Company’s consolidated net income, shareholders’ equity or cash flows.

2. Stock Options

The Company has adopted the provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”), and related interpretations in accounting for its employee stock options. Accordingly, under APB No. 25, compensation expense for stock option grants is recognized by the Company to the extent that the fair value of the underlying stock exceeds the exercise price of the option at the measurement date. As provided under Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” the Company has elected to continue to account for stock-based compensation in accordance with APB No. 25 and has provided the required additional pro forma disclosures.

If compensation expense for stock-based employee compensation plans had been determined using the fair value recognition provisions of SFAS No. 123, the Company’s net income and earnings per share would have instead been reported as the pro forma amounts indicated below:

	(Unaudited)						(Unaudited)
	Three Months Ended June 30,						Six Months Ended June 30,
(U.S. dollars in thousands, except share data)	2004			2003			2004			2003

Net income, as reported	$	104,282		$	61,784		$	191,737		$	114,270
Total stock-based employee compensation expense under fair value method, net of income taxes	(427		)	(1,547		)	(937		)	(3,292		)
Pro forma net income	$	103,855		$	60,237		$	190,800		$	110,978

Earnings per share – basic:
As reported	$	3.26		$	2.36		$	6.47		$	4.38
Pro forma	$	3.24		$	2.30		$	6.43		$	4.25
Earnings per share – diluted:
As reported	$	1.42		$	0.91		$	2.69		$	1.70
Pro forma	$	1.41		$	0.89		$	2.67		$	1.65

3. Accounting Pronouncements

In December 2003, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 46R (“FIN 46R”), “Consolidation of Variable Interest Entities.” This interpretation of Accounting Research Bulletin No. 51 (“ARB 51”), “Consolidated Financial Statements”, which replaces FASB Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities”, addresses consolidation by business enterprises of variable interest entities (“VIEs”). FIN 46R clarifies the application of ARB 51 to certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. In addition, FIN 46R modified FIN 46 to address certain technical corrections and implementation issues relating to FIN 46. Pursuant to FIN 46, if an enterprise has a controlling financial interest in a VIE, the assets, liabilities and results of operations of the variable interest entity must be included in the consolidated financial statements with those of the business enterprise. An enterprise with an interest in an entity to which the provisions of FIN 46 have not been applied as of December 24, 2003, shall apply the provisions of FIN 46R no later than the end of the first reporting period that ends after March 15, 2004. The provisions of FIN 46 applied immediately to VIEs created after January 31, 2003; however, for VIEs created prior to January 31, 2003 the provisions of FIN 46R are effective for the first year or interim period beginning after March 15, 2004. The provisions of FIN 46R are required to be applied to financial statements of public entities that have interests in VIEs, commonly referred to as special-purpose entities, for periods ending after December 15, 2003.

The Company concluded that, under FIN 46R, it is required to consolidate the assets, liabilities and results of operations (if any) of a certain managing general agency in which one of the Company’s subsidiaries has an investment. Such agency ceased producing business in 1999 and is currently running-off its operations. Based on current information, there are no assets or liabilities of such agency required to be reflected on the face of the Company’s consolidated financial statements that are not, or have not been previously, otherwise reflected therein. Therefore, the adoption of FIN 46R did not have a material impact on the Company’s consolidated financial statements as of or for the six months ended June 30, 2004.

In March 2004, the FASB’s Emerging Issues Task Force (“EITF”) reached a consensus regarding EITF 03-1, “The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments.” The consensus provides guidance for evaluating whether an investment is other-than-temporarily impaired. The EITF 03-1 guidance for determining other-than-temporary impairment will be effective beginning with the 2004 third quarter. The Company is currently evaluating the impact that EITF 03-1 may have on its consolidated financial statements.

4. Segment Information

The Company classifies its businesses into two underwriting segments – reinsurance and insurance – and a corporate and other segment (non-underwriting). The Company’s reinsurance and insurance operating segments each have segment managers who are responsible for the overall profitability of their respective segments and who are directly accountable to the Company’s chief operating decision makers, the President and Chief Executive Officer of ACGL and the Chief Financial Officer of ACGL. The chief operating decision makers do not assess performance, measure return on equity or make resource allocation decisions on a line of business basis. The Company determined its reportable operating segments using the management approach described in SFAS No. 131, “Disclosures About Segments of an Enterprise and Related Information.”

Management measures segment performance based on underwriting income or loss. The Company does not manage its assets by segment and, accordingly, investment income is not allocated to each underwriting segment. In addition, other revenue and expense items are not evaluated by segment. The accounting policies of the segments are the same as those used for the preparation of the Company’s consolidated financial statements. Inter-segment insurance business is allocated to the segment accountable for the underwriting results.

The reinsurance segment, or division, consists of the Company’s reinsurance underwriting subsidiaries. The reinsurance segment generally seeks to write significant lines on specialty property and casualty reinsurance treaties. Classes of business include casualty, casualty clash, marine and aviation, non-traditional, other specialty, property catastrophe, and property excluding property catastrophe (losses on a single risk, both excess of loss and pro rata).

The insurance segment, or division, consists of the Company’s insurance underwriting subsidiaries which primarily write on a direct basis. The insurance segment consists of eight product lines, including casualty, construction and surety, executive assurance, healthcare, professional liability, programs, property, marine and aviation, and other (primarily non-standard auto, collateralized protection business and certain programs).

The corporate and other segment (non-underwriting) includes net investment income, other fee income, net of related expenses, other income, other expenses incurred by the Company, net realized gains or losses, net foreign exchange gains or losses and non-cash compensation. The corporate and other segment also includes the results of Hales & Company Inc. (“Hales”), the Company’s merchant banking operations. Included in other (loss) income for the 2004 second quarter and six months ended June 30, 2004 is a charge of $4.5 million resulting from a write down of the carrying value of Hales (see Note 14, “Goodwill and Intangible Assets”).

The following table sets forth an analysis of the Company’s underwriting income by segment, together with a reconciliation of underwriting income to net income:
