1.	Summary of Significant Accounting Principles

(a) Principles of Financial Statement Presentation

This report should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2013 (the “2013 10-K”) and the Quarterly Reports on Form 10-Q for the quarters ended March 31, 2014 and June 30, 2014 of Alleghany Corporation (“Alleghany”), a Delaware corporation. Unless the context otherwise requires, references to “Alleghany” include Alleghany together with its subsidiaries.

Alleghany owns and manages operating subsidiaries and investments, anchored by a core position in property and casualty reinsurance and insurance. Alleghany was incorporated in 1984 under the laws of the State of Delaware and in December 1986, it succeeded to the business of its parent company, Alleghany Corporation, which was incorporated in 1929. Prior to March 6, 2012, Alleghany was primarily engaged, through its wholly-owned subsidiary Alleghany Insurance Holdings LLC (“AIHL”) and its subsidiaries, in the property and casualty insurance business. AIHL’s insurance operations are principally conducted by its subsidiaries RSUI Group, Inc. (“RSUI”), CapSpecialty, Inc. (“CapSpecialty”), formerly known as Capitol Transamerica Corporation, and Pacific Compensation Corporation (“PacificComp”). CapSpecialty has been a subsidiary of AIHL since January 2002, RSUI has been a subsidiary of AIHL since July 2003, and PacificComp has been a subsidiary of AIHL since July 2007. AIHL Re LLC (“AIHL Re”) has been a wholly-owned subsidiary of Alleghany since its formation in 2006. AIHL Re is a captive reinsurance company which provides reinsurance to Alleghany’s insurance operating subsidiaries and affiliates. On March 6, 2012, Alleghany consummated a merger transaction with Transatlantic Holdings, Inc. (“TransRe”), at which time TransRe became one of Alleghany’s wholly-owned subsidiaries, and Alleghany’s reinsurance operations commenced. Alleghany’s public equity investments, including those held by TransRe’s and AIHL’s operating subsidiaries, are managed primarily by Alleghany’s wholly-owned subsidiary Roundwood Asset Management LLC (“Roundwood”).

Although Alleghany’s primary sources of revenues and earnings are its reinsurance and insurance operations and investments, Alleghany manages, sources, executes and monitors certain private capital investments primarily through its wholly-owned subsidiary Alleghany Capital Corporation (“ACC”). ACC’s private capital investments include: (i) Stranded Oil Resources Corporation (“SORC”), an exploration and production company focused on enhanced oil recovery, headquartered in Austin, Texas; (ii) Bourn & Koch, Inc. (“BKI”), a manufacturer and remanufacturer/retrofitter of precision machine tools and supplier of replacement parts, headquartered in Rockford, Illinois; (iii) R.C. Tway Company, LLC (“Kentucky Trailer”), a manufacturer of custom trailers and truck bodies for the moving and storage industry and other markets, headquartered in Louisville, Kentucky; (iv) an approximately 39 percent equity interest in ORX Exploration, Inc. (“ORX”), a regional oil and gas exploration and production company, headquartered in New Orleans, Louisiana; and (v) a 30 percent equity interest in Jazwares, LLC (“Jazwares”), a toy and consumer electronics company, headquartered in Sunrise, Florida, acquired on July 31, 2014 for $60.3 million. Jazwares is accounted for under the equity-method of accounting and is included in corporate activities for segment reporting purposes. In addition, Alleghany owns and manages properties in the Sacramento, California region through its wholly-owned subsidiary Alleghany Properties Holdings LLC (“Alleghany Properties”).

Alleghany owned a minority stake in Homesite Group Incorporated (“Homesite”), a national, full-service, mono-line provider of homeowners insurance, until its sale to American Family Insurance Company, a Wisconsin-based mutual insurance company, on December 31, 2013.

The financial statements contained in this Quarterly Report on Form 10-Q are unaudited, but reflect all adjustments that, in the opinion of management, are necessary for a fair statement of results of the interim periods covered thereby. All adjustments are of a normal and recurring nature except as described herein.

The accompanying 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 (“GAAP”). All significant inter-company balances and transactions have been eliminated in consolidation. The results of Kentucky Trailer have been included in Alleghany’s consolidated financial statements beginning August 30, 2013, the date of ACC’s initial investment in Kentucky Trailer.

The portion of stockholders’ equity, net earnings and accumulated other comprehensive income that is not attributable to Alleghany stockholders is presented on the Consolidated Balance Sheets and the Consolidated Statements of Earnings and Comprehensive Income as noncontrolling interest.

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. Alleghany relies on historical experience and on various other assumptions that it believes to be reasonable under the circumstances to make judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from those reported results to the extent that those estimates and assumptions prove to be inaccurate. Changes in estimates are reflected in the consolidated statement of earnings and comprehensive income in the period in which the change is made. The results of operations for any interim period are not necessarily indicative of results for the full year.

(b) Other Significant Accounting Principles

Alleghany’s significant accounting principles can be found in Note 1 to Notes to Consolidated Financial Statements set forth in Part II, Item 8, “Financial Statements and Supplementary Data” of the 2013 10-K.

(c) Recent Accounting Standards

Future Application of Accounting Standards

In April 2014, the Financial Accounting Standards Board (the “FASB”) issued guidance that changed the criteria for reporting discontinued operations. Under the new guidance, only disposals that represent a strategic shift in operations qualify as discontinued operations. In addition, the new guidance requires expanded disclosures about discontinued operations. This guidance is effective in the first quarter of 2015. Alleghany will adopt this guidance in the first quarter of 2015, and Alleghany does not currently believe that the implementation will have an impact on its results of operations and financial condition.

In May 2014, the FASB, together with the International Accounting Standards Board, issued guidance on the recognition of revenue from contracts with customers. Under the new guidance, revenue is recognized as the transfer of goods and services to customers takes place, and in amounts that reflect the payment or payments that are expected to be received from the customers for those goods and services. The new guidance also requires new disclosures about revenue. Insurance- and reinsurance-related revenues are not impacted by this guidance. This guidance is effective in the first quarter of 2017 for public entities, with earlier adoption not permitted. Alleghany will adopt this guidance in the first quarter of 2017, and Alleghany does not currently believe that the implementation will have a material impact on its results of operations and financial condition.
