1. Summary of Significant Accounting Principles

(a) Principles of Financial Statement Presentation

This Quarterly Report on Form 10-Q (this “Form 10-Q”) should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 Form 10-K”) and the Quarterly Reports on Form 10-Q for the quarters ended March 31, 2017 and June 30, 2017 of Alleghany Corporation (“Alleghany”).

Alleghany, a Delaware corporation, owns and manages certain operating subsidiaries and investments, anchored by a core position in property and casualty reinsurance and insurance. Through its wholly-owned subsidiary Alleghany Insurance Holdings LLC (“AIHL”) and its subsidiaries, Alleghany is engaged in the property and casualty insurance business. AIHL’s insurance operations are principally conducted by its subsidiaries RSUI Group, Inc. (“RSUI”), CapSpecialty, Inc. (“CapSpecialty”) 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”), a captive reinsurance company which provides reinsurance to Alleghany’s insurance operating subsidiaries and affiliates, has been a wholly-owned subsidiary of Alleghany since its formation in May 2006. Alleghany’s reinsurance operations commenced on March 6, 2012 when Alleghany consummated a merger with Transatlantic Holdings, Inc. (“TransRe”) and TransRe became one of Alleghany’s wholly-owned subsidiaries.

Although Alleghany’s primary sources of revenues and earnings are its reinsurance and insurance operations and investments, Alleghany also sources, executes, manages and monitors certain private capital investments primarily through its wholly-owned subsidiary Alleghany Capital Corporation (“Alleghany Capital”). Alleghany Capital’s investments are included in other activities for segment reporting purposes and include:

On April 15, 2016, Alleghany Capital acquired an additional 50 percent of Jazwares’ outstanding equity, bringing its equity ownership interest to 80 percent and, as of that date, the results of Jazwares have been included in Alleghany’s consolidated results. Prior to April 15, 2016, Jazwares was accounted for under the equity method of accounting.

In addition, Alleghany owns and manages properties in the Sacramento, California region through its wholly-owned subsidiary Alleghany Properties Holdings LLC (“Alleghany Properties”). Alleghany’s public equity investments are managed primarily through Alleghany’s wholly-owned subsidiary Roundwood Asset Management LLC.

On September 12, 2017, AIHL signed a definitive agreement to sell PacificComp to CopperPoint Mutual Insurance Company (“CopperPoint”) for total cash consideration of approximately $150 million. In connection with the transaction, AIHL Re will continue to provide adverse development reinsurance coverage on PacificComp’s pre-acquisition claims, subject to certain terms and conditions. The transaction, which is subject to customary regulatory review and approvals, is expected to close on December 31, 2017. Upon closing, Alleghany expects to record an estimated after-tax gain of approximately $25 million, which amount includes a tax benefit. As of September 30, 2017, PacificComp’s total assets were $440.6 million, consisting primarily of debt securities, and PacificComp’s total liabilities were $313.7 million, consisting primarily of loss and loss adjustment expenses (“LAE”) reserves.

Unless the context otherwise requires, references to “Alleghany” include Alleghany together with its subsidiaries.

Table of Contents

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 U.S. (“GAAP”). All material inter-company balances and transactions have been eliminated in consolidation.

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 interests. Because all noncontrolling interests have the option to sell their ownership interests to Alleghany in the future (generally through 2024), the portion of stockholders’ equity that is not attributable to Alleghany stockholders is presented on the Consolidated Balance Sheets as redeemable noncontrolling interests for all periods presented. During the first nine months of 2017, Bourn & Koch had approximately 11 percent noncontrolling interests outstanding, Kentucky Trailer had approximately 21 percent noncontrolling interests outstanding, IPS had approximately 16 percent noncontrolling interests outstanding and Jazwares had approximately 20 percent noncontrolling interests outstanding. W&W|AFCO Steel had approximately 20 percent noncontrolling interests outstanding from its April 28, 2017 acquisition date through September 30, 2017.

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 as of 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 Statements of Earnings and Comprehensive Income in the period in which the changes are made.

(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 2016 Form 10-K.

(c) Recent Accounting Standards

Recently Adopted

In May 2015, the Financial Accounting Standards Board (the “FASB”) issued guidance that requires disclosures related to short-duration insurance contracts. The guidance applies to property and casualty insurance and reinsurance entities, among others, and requires the following annual disclosure related to the liability for loss and LAE: (i) net incurred and paid claims development information by accident year for up to ten years; (ii) a reconciliation of incurred and paid claims development information to the aggregate carrying amount of the liability for loss and LAE; (iii) liabilities for losses that have been incurred but not yet reported by accident year and in total; (iv) a description of reserving methodologies (as well as any changes to those methodologies); (v) quantitative information about claim frequency by accident year; and (vi) the average annual percentage payout of incurred claims by age and accident year. In addition, the guidance also requires insurance entities to disclose for annual and interim reporting periods a roll-forward of the liability for loss and LAE. This guidance was effective for annual periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2016, with early adoption permitted. Alleghany adopted this guidance as of December 31, 2016 and the implementation did not have an impact on its results of operations and financial condition. See Note 5 of this Form 10-Q and Note 1(k) and Note 6 to Notes to Consolidated Financial Statements set forth in Part II, Item 8, “Financial Statements and Supplementary Data” of the 2016 Form 10-K for the new disclosures.

Future Application of Accounting Standards

In May 2014, the FASB, together with the International Accounting Standards Board, issued guidance on the recognition of revenue from contracts with customers. Under this 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. This guidance also requires new disclosures about revenue. Revenues related to insurance and reinsurance are not impacted by this guidance. This guidance is effective in the first quarter of 2018 for public entities, with early adoption permitted in 2017. Alleghany will adopt this guidance in the first quarter of 2018 and does not currently believe that the implementation will have a material impact on its results of operations and financial condition.

In January 2016, the FASB issued guidance that changes the recognition and measurement of certain financial instruments. This guidance requires investments in equity securities (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. For equity securities that do not have readily determinable fair values, measurement may be at cost, adjusted for any impairment and changes resulting from observable price changes for a similar investment of the same issuer. This guidance also changes the presentation and disclosure of financial instruments by: (i) requiring that financial instrument disclosures of fair value use the exit price notion; (ii) requiring separate presentation of financial assets and financial liabilities by measurement category and form, either on the balance sheet or the accompanying notes to the financial statements; (iii) requiring separate presentation in other comprehensive income for the portion of the change in a liability’s fair value resulting

Table of Contents

from instrument-specific credit risk when an election has been made to measure the liability at fair value; and (iv) eliminating the requirement to disclose the methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost on the balance sheet. This guidance is effective for fiscal years beginning after December 15, 2017 for public entities, including interim periods within those fiscal years. Except for the change in presentation for instrument-specific credit risk, this guidance does not permit early adoption. Alleghany will adopt this guidance in the first quarter of 2018. As of January 1, 2018, unrealized gains or losses of equity securities, net of deferred taxes, will be reclassified from accumulated other comprehensive income to retained earnings. Subsequently, all changes in unrealized gains or losses of equity securities, net of deferred taxes, will be presented in the Consolidated Statements of Earnings rather than the Consolidated Statements of Comprehensive Income. Alleghany does not currently believe that the implementation will have a material impact on its financial condition. See Note 3(a) of this Form 10-Q for further information on Alleghany’s unrealized gains and losses of equity securities.

In February 2016, the FASB issued guidance on leases. Under this guidance, a lessee is required to recognize lease liabilities and corresponding right-of-use assets for leases with terms of more than one year, whereas under current guidance, a lessee is only required to recognize assets and liabilities for those leases qualifying as capital leases. This guidance also requires new disclosures about the amount, timing and uncertainty of cash flows arising from leases. The accounting by lessors is to remain largely unchanged. This guidance is effective in the first quarter of 2019 for public entities, with early adoption permitted. A modified retrospective transition approach is required for all leases in existence as of, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Alleghany will adopt this guidance in the first quarter of 2019 and does not currently believe that the implementation will have a material impact on its results of operations and financial condition. See Note 12(b) to Notes to Consolidated Financial Statements set forth in Part II, Item 8, “Financial Statements and Supplementary Data” of the 2016 Form 10-K for further information on Alleghany’s leases.

In June 2016, the FASB issued guidance on credit losses. Under this guidance, a company is required to measure all expected credit losses on loans, reinsurance recoverables and other financial assets accounted for at cost or amortized cost, as applicable. Estimates of expected credit losses are to be based on historical experience, current conditions and reasonable and supportable forecasts. Credit losses for securities accounted for on an available-for-sale (“AFS”) basis are to be measured in a manner similar to GAAP as currently applied and cannot exceed the amount by which the fair value is less than the amortized cost. Credit losses for all financial assets are to be recorded through an allowance for credit losses. Subsequent reversals in credit loss estimates are permitted and are to be recognized in earnings. This guidance also requires new disclosures about the significant estimates and judgments used in estimating credit losses, as well as the credit quality of financial assets. This guidance is effective in the first quarter of 2020 for public entities, with early adoption permitted. Alleghany will adopt this guidance in the first quarter of 2020 and does not currently believe that the implementation will have a material impact on its results of operations and financial condition.

In January 2017, the FASB issued guidance that simplifies the subsequent measurement of goodwill. Under this guidance, if an initial qualitative assessment indicates that the fair value of an operating subsidiary may be less than its carrying amount, an impairment charge is recognized for the amount by which the carrying amount of the operating subsidiary exceeds its estimated fair value. Any resulting impairment loss recognized cannot exceed the total amount of goodwill associated with the operating subsidiary. This guidance is effective in the first quarter of 2020 for public entities, with early adoption permitted. Alleghany will adopt this guidance in the first quarter of 2020 and does not currently believe that the implementation will have a material impact on its results of operations and financial condition.

In March 2017, the FASB issued guidance that reduces the amortization period for the premium on certain purchased callable debt securities to the earliest call date. The guidance applies specifically to noncontingent call features that are callable at a predetermined and fixed price and date. The accounting for purchased callable debt securities held at a discount is not affected. This guidance is effective in the first quarter of 2019 for public entities, with early adoption permitted. Alleghany will adopt this guidance in the fourth quarter of 2017, and will record a cumulative effect reduction directly to opening 2017 retained earnings and an offsetting increase in opening 2017 accumulated other comprehensive income at that time. Alleghany does not currently believe that the implementation will have a material impact on its results of operations and financial condition.

In August 2017, the FASB issued guidance that simplifies the requirements to achieve hedge accounting, better reflects the economic results of hedging in the financial statements and better aligns hedge accounting with a company’s risk management activities. This guidance is effective in the first quarter of 2019 for public entities, with early adoption permitted. Alleghany will adopt this guidance in the first quarter of 2019 and does not currently believe that the implementation will have a material impact on its results of operations and financial condition.

Table of Contents

In the nine months ended September 30, 2017, Alleghany transferred $7.2 million of financial instruments out of Level 3 principally due to an increase in observable inputs related to the valuation of such assets and, specifically, an increase in broker quotes. Of the $7.2 million of transfers, $4.8 million related to U.S. corporate bonds and $2.4 million related to common stock. There were no transfers of financial instruments out of Level 3 in the third quarter of 2017.

In the three and nine months ended September 30, 2017, Alleghany transferred $0.8 million and $5.5 million, respectively, of financial instruments into Level 3 principally due to a decrease in observable inputs related to the valuation of such assets and, specifically, a decrease in broker quotes. Of the $5.5 million of transfers, $3.8 million related to U.S. corporate bonds, $1.4 million related to common stock and $0.3 million related to foreign corporate bonds. There were no other material transfers between Levels 1, 2 or 3 in the three and nine months ended September 30, 2017.

In the three and nine months ended September 30, 2016, Alleghany transferred $5.1 million and $5.4 million, respectively, of debt securities out of Level 3 principally due to an increase in observable inputs related to the valuation of such assets and, specifically, an increase in broker quotes. Of the $5.4 million of transfers, $5.1 million related to U.S. corporate bonds and $0.3 million related to other invested assets.

In the three and nine months ended September 30, 2016, Alleghany transfered $5.7 million and $8.4 million, respectively, of securities into Level 3 principally due to a decrease in observable inputs related to the valuation of such assets, and specifically, a decrease in broker quotes. Of the $8.4 million of transfers, $5.5 million related to U.S. corporate bonds, $1.9 million related to foreign corporate bonds and $1.0 million related to common stock. There were no other material transfers between Levels 1, 2 or 3 in the three and nine months ended September 30, 2016.

(b) Contractual Maturity

The amortized cost or cost and estimated fair value of debt securities by contractual maturity as of September 30, 2017 are presented below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

(c) Net Investment Income

The following table presents net investment income for the three and nine months ended September 30, 2017 and 2016:

As of September 30, 2017, non-income producing invested assets were immaterial.

(d) Realized Gains and Losses

The proceeds from sales of AFS securities were $1.6 billion and $0.8 billion for the three months ended September 30, 2017 and 2016, respectively, and $5.8 billion and $5.2 billion for the nine months ended September 30, 2017 and 2016, respectively.

Realized capital gains and losses for the three and nine months ended September 30, 2017 primarily reflect sales of equity securities and certain exchange-traded funds. Realized capital gains in the first nine months of 2017 include the sale of certain equity securities resulting from a partial restructuring of the equity portfolio. Realized capital gains and losses for the three and nine months ended September 30, 2016 primarily reflect sales of equity and debt securities. In addition, Alleghany Capital recognized a gain of $13.2 million on April 15, 2016 in connection with the acquisition of an additional 50 percent equity ownership in Jazwares, when its pre-existing 30 percent equity ownership was remeasured at estimated fair value (the “Jazwares Remeasurement Gain”).

Table of Contents

The following table presents amounts of gross realized capital gains and gross realized capital losses for the three and nine months ended September 30, 2017 and 2016:

Gross realized loss amounts exclude OTTI losses, as discussed below.

(e) OTTI Losses

Alleghany holds its equity and debt securities as AFS and, as such, these securities are recorded at fair value. Alleghany continually monitors the difference between cost and the estimated fair value of its equity and debt investments, which involves uncertainty as to whether declines in value are temporary in nature. The analysis of a security’s decline in value is performed in its functional currency. If the decline is deemed temporary, Alleghany records the decline as an unrealized loss in stockholders’ equity. If the decline is deemed to be other than temporary, Alleghany writes its cost-basis or amortized cost-basis down to the fair value of the security and records an OTTI loss on its statement of earnings. In addition, any portion of such decline related to a debt security that is believed to arise from factors other than credit is recorded as a component of other comprehensive income rather than charged against earnings.

Management’s assessment of equity securities initially involves an evaluation of all securities that are in an unrealized loss position, regardless of the duration or severity of the loss, as of the applicable balance sheet date. Such initial review consists primarily of assessing whether: (i) there has been a negative credit or news event with respect to the issuer that could indicate the existence of an OTTI; and (ii) Alleghany has the ability and intent to hold an equity security for a period of time sufficient to allow for an anticipated recovery (generally considered to be 12 months from the balance sheet date).

To the extent that an equity security in an unrealized loss position is not impaired based on the initial review described above, Alleghany then further evaluates such equity security and deems it to be other than temporarily impaired if it has been in an unrealized loss position for 12 months or more or if its unrealized loss position is greater than 50 percent of its cost, absent compelling evidence to the contrary.

Alleghany then evaluates those equity securities where the unrealized loss is at least 20 percent of cost as of the balance sheet date or that have been in an unrealized loss position continuously for six months or more preceding the balance sheet date. This evaluation takes into account quantitative and qualitative factors in determining whether such securities are other than temporarily impaired including: (i) market valuation metrics associated with the equity security (such as dividend yield and price-to-earnings ratio); (ii) current views on the equity security, as expressed by either Alleghany’s internal stock analysts and/or by third-party stock analysts or rating agencies; and (iii) credit or news events associated with a specific issuer, such as negative news releases and rating agency downgrades with respect to the issuer of the equity security.

Debt securities in an unrealized loss position are evaluated for OTTI if they meet any of the following criteria: (i) they are trading at a discount of at least 20 percent to amortized cost for an extended period of time (nine consecutive months or more); (ii) there has been a negative credit or news event with respect to the issuer that could indicate the existence of an OTTI; or (iii) Alleghany intends to sell, or it is more likely than not that Alleghany will sell, the debt security before recovery of its amortized cost basis.

If Alleghany intends to sell, or it is more likely than not that Alleghany will sell, a debt security before recovery of its amortized cost basis, the total amount of the unrealized loss position is recognized as an OTTI loss in earnings. To the extent that a debt security that is in an unrealized loss position is not impaired based on the preceding, Alleghany will consider a debt security to be impaired when it believes it to be probable that Alleghany will not be able to collect the entire amortized cost basis. For debt securities in an unrealized loss position as of the end of each quarter, Alleghany develops a best estimate of the present value of expected cash flows. If the results of the cash flow analysis indicate that Alleghany will not recover the full amount of its amortized cost basis in the debt security, Alleghany records an OTTI loss in earnings equal to the difference between the present value of expected cash flows and the amortized cost basis of the debt security. If applicable, the difference between the total unrealized loss position on the debt security and the OTTI loss recognized in earnings is the non-credit related portion, which is recorded as a component of other comprehensive income.

In developing the cash flow analyses for debt securities, Alleghany considers various factors for the different categories of debt securities. For municipal bonds, Alleghany takes into account the taxing power of the issuer, source of revenue, credit risk and

13

Table of Contents

enhancements and pre-refunding. For mortgage and asset-backed securities, Alleghany discounts its best estimate of future cash flows at an effective rate equal to the original effective yield of the security or, in the case of floating rate securities, at the current coupon. Alleghany’s models include assumptions about prepayment speeds, default and delinquency rates, underlying collateral (if any), credit ratings, credit enhancements and other observable market data. For corporate bonds, Alleghany reviews business prospects, credit ratings and available information from asset managers and rating agencies for individual securities.

OTTI losses in the first nine months of 2017 reflect $13.1 million of unrealized losses that were deemed to be other than temporary and, as such, were required to be charged against earnings. Of the $13.1 million of OTTI losses, $11.8 million related to equity securities, primarily in the retail sector, and $1.3 million related to debt securities. The determination that unrealized losses on equity and debt securities were other than temporary was primarily due to the duration of the decline in the fair value of equity and debt securities relative to their costs. Of the $13.1 million of OTTI losses, $6.1 million was incurred in the third quarter of 2017.

OTTI losses in the first nine months of 2016 reflect $38.2 million of unrealized losses that were deemed to be other than temporary and, as such, were required to be charged against earnings. Of the $38.2 million of OTTI losses, $16.6 million related to equity securities, primarily in the retail, financial services, technology and chemical sectors, and $21.6 million related to debt securities, primarily in the energy sector. The determination that unrealized losses on equity and debt securities were other than temporary was primarily due to the severity and duration of the decline in the fair value of equity and debt securities relative to their costs. Of the $38.2 million of OTTI losses, $11.7 million was incurred in the third quarter of 2016.

Upon the ultimate disposition of the securities for which OTTI losses have been recorded, a portion of the loss may be recoverable depending on market conditions at the time of disposition. After adjusting the cost basis of securities for the recognition of OTTI losses, the remaining gross unrealized investment losses for debt and equity securities as of September 30, 2017 were deemed to be temporary, based on, among other factors: (i) the duration of time and the relative magnitude to which the fair value of these investments had been below cost were not indicative of an OTTI loss; (ii) the absence of compelling evidence that would cause Alleghany to call into question the financial condition or near-term business prospects of the issuer of the security; and (iii) Alleghany’s ability and intent to hold the security for a period of time sufficient to allow for any anticipated recovery.

Alleghany may ultimately record a realized loss after having originally concluded that the decline in value was temporary. Risks and uncertainties are inherent in the methodology. Alleghany’s methodology for assessing other than temporary declines in value contains inherent risks and uncertainties which could include, but are not limited to, incorrect assumptions about financial condition, liquidity or future prospects, inadequacy of any underlying collateral and unfavorable changes in economic conditions or social trends, interest rates or credit ratings.
