AIHL’s insurance business is conducted through its wholly-owned subsidiaries RSUI Group, Inc. (“RSUI”), Capitol Transamerica Corporation and Platte River Insurance Company (collectively “CATA”), and Pacific Compensation Corporation (“PCC”). AIHL Re LLC (“AIHL Re”), a captive reinsurance subsidiary of AIHL, has in the past provided reinsurance to Alleghany operating units and affiliates. Alleghany’s equity investments, including those held by AIHL’s insurance operating units, are managed primarily by Alleghany Capital Partners LLC, an indirect, wholly-owned subsidiary of Alleghany. Alleghany also owns and manages properties in the Sacramento, California region through its subsidiary Alleghany Properties Holdings LLC (“Alleghany Properties”). In addition, Alleghany owns approximately 33 percent of the outstanding shares of common stock of Homesite Group Incorporated (“Homesite”), a national, full-service, mono-line provider of homeowners insurance, and approximately 38 percent of ORX Exploration, Inc. (“ORX”), a regional oil and gas exploration and production company. Alleghany also makes strategic investments in operating companies and conducts other activities at the parent level. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The financial statements contained in this Quarterly Report on Form 10-Q are unaudited, but reflect all adjustments which, in the opinion of management, are necessary to a fair statement of results of the interim periods covered thereby. All adjustments are of a normal and recurring nature except as described herein. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The accompanying unaudited consolidated financial statements include the results of Alleghany and its wholly-owned and majority-owned subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All significant inter-company balances and transactions have been eliminated in consolidation. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those reported results to the extent that those estimates and assumptions prove to be inaccurate. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Certain prior year amounts have been reclassified to conform to the 2011 presentation. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> </div>

Recent Accounting Standards</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt"><i>Recently Adopted</i> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In July 2010, the Financial Accounting Standards Board (“FASB”) issued guidance that provides for additional financial statement disclosure regarding financing receivables, including the credit quality and allowance for credit losses associated with such assets. This guidance is generally effective for interim and annual periods beginning after December 15, 2010, with certain disclosures effective for interim and annual periods ending on or after December 31, 2010. Alleghany fully adopted this guidance in the 2011 first quarter, and the implementation did not have any impact on its results of operations and financial condition. </div> <div align="left" style="font-size: 10pt; margin-top: 12pt"><i>Future Application of Accounting Standards</i> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In October 2010, the FASB issued guidance that provides additional clarification for costs associated with acquiring or renewing insurance contracts. This guidance states that only incremental, direct costs associated with the successful acquisition of a new or renewal insurance contract may be capitalized as deferred acquisition costs. Furthermore, such costs: (i) must be essential to the contract transaction; (ii) would not have been incurred had the contract transaction not occurred; and (iii) must be related directly to the acquisition activities involving underwriting, policy issuance and processing, medical and inspection, and sales force contract selling. Advertising costs should be included in deferred acquisition costs only if the capitalization criteria in separate “direct-response” advertising guidance within GAAP are met. All other acquisition-related costs and other expenses should be charged to expense as incurred. This guidance is effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted (but only at the beginning of an entity’s annual reporting period). Alleghany will adopt this guidance in the 2012 first quarter, and Alleghany does not currently believe that the implementation will have a material impact on its results of operations and financial condition. </div> </div>

(“World Minerals”), to Imerys USA, Inc. (the “Purchaser”), a wholly-owned subsidiary of Imerys, S.A., pursuant to a Stock Purchase Agreement, dated as of May 19, 2005, by and among the Purchaser, Imerys, S.A. and Alleghany (the “Stock Purchase Agreement”). Pursuant to the Stock Purchase Agreement, Alleghany undertook certain indemnification obligations, including a general indemnification for breaches of representations and warranties set forth in the Stock Purchase Agreement (the “Contract Indemnification”) and a special indemnification (the “Products Liability Indemnification”) related to products liability claims arising from events that occurred during pre-closing periods, including the period of Alleghany ownership (the “Alleghany Period”). </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The Products Liability Indemnification is divided into two parts, the first relating to products liability claims arising in respect of events occurring during the period prior to Alleghany’s acquisition of the World Minerals business from Johns Manville Corporation, Inc., formerly known as Manville Sales Corporation (“Manville”), in July 1991 (the “Manville Period”), and the second relating to products liability claims arising in respect of events occurring during the period of Alleghany ownership. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Under the terms of the Stock Purchase Agreement, Alleghany will provide indemnification at a rate of 100 percent for the first $100.0 million of losses arising from products liability claims relating to the Manville Period and at a rate of 50 percent for the next $100.0 million of such losses, so that Alleghany’s maximum indemnification obligation in respect of products liability claims relating to the Manville Period is $150.0 million. This indemnification obligation in respect of Manville Period products liability claims will expire on July 31, 2016. The Stock Purchase Agreement states that it is the intention of the parties that, with regard to losses incurred in respect of products liability claims relating to the Manville Period, recovery should first be sought from Manville, and that Alleghany’s indemnification obligation in respect of products liability claims relating to the Manville Period is intended to indemnify the Purchaser for such losses which are not recovered from Manville within a reasonable period of time after recovery is sought from Manville. In connection with World Minerals’ acquisition of the assets of the industrial minerals business of Manville in 1991, Manville agreed to indemnify World Minerals for certain products liability claims, in respect of products of the industrial minerals business manufactured during the Manville Period, asserted against World Minerals through July 31, 2006. In June 2006, Manville agreed to extend its indemnification for such claims asserted against World Minerals through July 31, 2009. Notwithstanding the expiration of the Manville indemnity on July 31, 2009, World Minerals did not, as part of its 1991 acquisition of the assets of Manville’s industrial minerals business assets, assume liability for product liability claims to the extent that such claims relate, in whole or in part, to the Manville Period, and Manville should continue to be responsible for such claims. The Stock Purchase Agreement provides that Alleghany has no responsibility for products liability claims arising in respect of events occurring after the closing, and that any products liability claims involving both pre-closing and post-closing periods will be apportioned on an equitable basis. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     With respect to the Contract Indemnification, substantially all of the representations and warranties to which the Contract Indemnification applies survived until July 14, 2007, with the exception of certain representations and warranties such as those related to environmental, real estate and tax matters, which survive for longer periods and generally, except for tax and certain other matters, apply only to aggregate losses in excess of $2.5 million, up to a maximum of approximately $123.0 million. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Additional information concerning the Products Liability Indemnification and Contract Indemnification can be found in Note 13 to the Notes to the Consolidated Financial Statements set forth in Item 8 of the 2010 10-K. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Based on Alleghany’s historical experience and other analyses, in July 2005, Alleghany established a $0.6 million reserve in connection with the Products Liability Indemnification for the Alleghany Period.

Reinsurance</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     As discussed in the 2010 10-K, RSUI reinsures its property lines of business through a program consisting of surplus share treaties, facultative placements, per risk and catastrophe excess of loss treaties. RSUI’s catastrophe reinsurance program (which covers catastrophe risks including, among others, windstorms and earthquakes) and per risk reinsurance program run on an annual basis from May 1 to the following April 30 and thus expired on April 30, 2011. RSUI placed all of its catastrophe reinsurance program for the 2011-2012 period, and the new program is similar to the expired program. The new reinsurance program provides coverage in two layers for $400.0 million of losses in excess of a $100.0 million net retention after application of the surplus share treaties, facultative reinsurance and per risk covers. The first layer provides coverage for $100.0 million of losses, before a 47.0 percent co-participation by RSUI (compared with a 33.0 percent co-participation under the expired program), in excess of the $100.0 million net retention, and the second layer provides coverage for $300.0 million of losses, before a 5 percent co-participation by RSUI, in excess of $200.0 million. In addition, RSUI’s property per risk reinsurance program for the 2011-2012 period provides RSUI with coverage for $90.0 million of losses, before a 10.0 percent co-participation by RSUI, in excess of a $10.0 million net retention per risk after application of the surplus share treaties and facultative reinsurance. As discussed in Note 5(a) to the Notes to the Consolidated Financial Statements set forth in Item 8 of the 2010 10-K, RSUI reinsures its other lines of business through quota share treaties, except for professional liability and binding authority lines where RSUI retains all of such business. </div> </div>

Fair value measurements are not adjusted for transaction costs. In addition, GAAP has a three-tiered hierarchy for inputs used in management’s determination of fair value of financial instruments that emphasizes the use of observable inputs over the use of unobservable inputs by requiring that the observable inputs be used when available. Observable inputs are market participant assumptions based on market data obtained from sources independent of the reporting entity. Unobservable inputs are the reporting entity’s own assumptions about market participant assumptions based on the best information available under the circumstances. In assessing the appropriateness of using observable inputs in making its fair value determinations, Alleghany considers whether the market for a particular security is “active” or not based on all the relevant facts and circumstances. For example, Alleghany may consider a market to be inactive if there are relatively few recent transactions or if there is a significant decrease in market volume. Furthermore, Alleghany considers whether observable transactions are “orderly” or not. Alleghany does not consider a transaction to be orderly if there is evidence of a forced liquidation or other distressed condition, and as such, little or no weight is given to that transaction as an indicator of fair value. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The hierarchy is broken down into three levels based on the reliability of inputs as follows: </div> <div style="margin-top: 6pt"> <table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"> <tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"> <td width="2%" style="background: transparent"> </td> <td width="3%" nowrap="nowrap" align="left"><b>•</b></td> <td width="1%"> </td> <td>“Level 1” — Valuations are based on unadjusted quoted prices in active markets for identical, unrestricted assets. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these assets does not involve any meaningful degree of judgment. An active market is defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Alleghany’s Level 1 assets generally include publicly traded common stocks and debt securities issued directly by the U.S. Government, where Alleghany’s valuations are based on quoted market prices.</td> </tr> <tr> <td style="font-size: 6pt"> </td> </tr> <tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"> <td width="2%" style="background: transparent"> </td> <td width="3%" nowrap="nowrap" align="left"><b>•</b></td> <td width="1%"> </td> <td>“Level 2” — Valuations are based on quoted market prices where such markets are not deemed to be sufficiently “active.” In such circumstances, additional valuation metrics will be used which involve direct or indirect observable market inputs. Alleghany’s Level 2 assets generally include preferred stocks and debt securities other than debt issued directly by the U.S. Government. Alleghany’s Level 2 liabilities include the Senior Notes. Substantially all of the determinations of value in this category are based on a single quote from third-party dealers and pricing services. As Alleghany generally does not make any adjustments thereto, such quote typically constitutes the sole input in its determination of the fair value of these types of securities. In developing a quote, such third parties will use the terms of the security and market-based inputs. Terms of the security include coupon, maturity date, and any special provisions that may, for example, enable the investor, at its election, to redeem the security prior to its scheduled maturity date. Market-based inputs include the level of interest rates applicable to comparable securities in the market place and current credit rating(s) of the security. Such quotes are generally non-binding.</td> </tr> <tr> <td style="font-size: 6pt"> </td> </tr> <tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"> <td width="2%" style="background: transparent"> </td> <td width="3%" nowrap="nowrap" align="left"><b>•</b></td> <td width="1%"> </td> <td>“Level 3” — Valuations are based on inputs that are unobservable and significant to the overall fair value measurement.

Net asset value quotes from the third-party general partner of the entity in which such investment is held, which will often be based on unobservable market inputs, constitute the primary input in Alleghany’s determination of the fair value of such assets.</td> </tr> </table> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Alleghany validates the reasonableness of its fair value determinations for Level 2 securities by testing the methodology of the relevant third-party dealer or pricing service that provides the quotes upon which the fair value determinations are made. Alleghany tests the methodology by comparing such quotes with prices from executed market trades when such trades occur. Alleghany discusses with the relevant third-party dealer or pricing service any identified material discrepancy between the quote derived from its methodology and the executed market trade in order to resolve the discrepancy. Alleghany uses the quote from the third-party dealer or pricing service unless Alleghany determines that the methodology used to produce such quote is not in compliance with GAAP. In addition to such procedures, Alleghany also compares the aggregate amount of the fair value for such Level 2 securities with the aggregate fair value provided by a third-party financial institution. Furthermore, Alleghany reviews the reasonableness of its classification of securities within the three-tiered hierarchy to ensure that the classification is consistent with GAAP. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> <div align="left" style="font-size: 10pt;

Of the debt securities that were in an unrealized loss position, all were mortgage and asset-backed securities, and states, municipalities and political subdivision bonds.

The lower effective tax rate in 2011 primarily reflects the impact of higher dividends received deductions in the first three months of 2011, partially offset by the absence of a permanent tax benefit significant in the 2010 period, which related to a finalization of Alleghany’s unused foreign tax credits arising from its prior ownership of World Minerals which was sold on July 14, 2005. </div> </div>
