Overview

We are a multinational specialty property and casualty insurer focused on generating consistent underwriting profits. We provide insurance coverage for small businesses and products with high volumes of insureds and loss profiles that we believe are predictable. We target lines of insurance that we believe generally are underserved by the market. We have grown by hiring teams of underwriters with expertise in our specialty lines, through acquisitions of companies and assets that, in each case, provide access to distribution networks and renewal rights to established books of specialty insurance business. We have operations in four business segments:
• Small Commercial Business. We provide workers' compensation, commercial package and other commercial insurance lines produced by wholesale agents, retail agents and brokers in the United States.

• Specialty Risk and Extended Warranty. We provide coverage for consumer and commercial goods and custom designed coverages, such as accidental damage plans and payment protection plans offered in connection with the sale of consumer and commercial goods, in the United States and Europe, and certain niche property, casualty and specialty liability risks in the United States and Europe, including general liability, employers' liability and professional and medical liability.

• Specialty Program. We write commercial insurance for narrowly defined classes of insureds, requiring an in-depth knowledge of the insured's industry segment, through general and other wholesale agents.

• Personal Lines Reinsurance. We reinsure 10% of the net premiums of the GMACI personal lines business, pursuant to the Personal Lines Quota Share with the GMACI personal lines insurance companies. See discussion below related to ACAC investment.

We transact business primarily through our eleven Insurance Subsidiaries:

Insurance, particularly workers' compensation, is, generally, affected by seasonality. The first quarter generally produces greater premiums than subsequent quarters. Nevertheless, the impact of seasonality on our Small Commercial Business and Specialty Program segments has not been significant. We believe that this is because we serve many small businesses in different geographic locations. In addition, we believe seasonality may be muted by our acquisition activity.

We evaluate our operations by monitoring key measures of growth and profitability, including return on equity and net combined ratio. Our return on equity was 17.5%, 21.2% and 22.2% for the years ended December 31, 2012, 2011 and 2010, respectively. Our overall financial objective is to produce a return on equity of 15.0% or more over the long term. In addition, we target a net combined ratio of 95.0% or lower over the long term, while seeking to maintain optimal operating leverage in our Insurance Subsidiaries commensurate with our
A.M. Best rating objectives. Our net combined ratio was 89.5%, 89.0% and 85.3% for the years ended December 31, 2012, 2011 and 2010, respectively. A key factor in achieving our targeted net combined ratio is a continuous focus on our net expense ratio. Our strategy across our segments is to maintain premium rates, deploy capital judiciously, manage our expenses and focus on the sectors in which we have expertise, which we believe should provide opportunities for greater returns.

Investment income is also an important part of our business. Because the period of time between our receipt of premiums and the ultimate settlement of claims is often several years or longer, we are able to invest cash from premiums for significant periods of time. Our net investment income was $68.2 million, $55.5 million and $50.5 million for the years ended December 31, 2012, 2011 and 2010, respectively. We held 19.0% and 21.1% of total invested assets in cash and cash equivalents as of December 31, 2012 and 2011, respectively.

Our most significant balance sheet liability is our reserves for loss and loss adjustment expense. We record reserves for estimated losses under insurance policies that we write and for loss adjustment expenses related to the investigation and settlement of policy claims. Our reserves for loss and loss adjustment expenses represent the estimated cost of all reported and unreported loss and loss adjustment expenses incurred and unpaid at any given point in time based on known facts and

circumstances. Our reserves for loss and loss adjustment expenses incurred and unpaid are not discounted using present value factors. Our loss reserves are reviewed at least annually by our external actuaries. Reserves are based on estimates of the most likely ultimate cost of individual claims. These estimates are inherently uncertain. Judgment is required to determine the relevance of our historical experience and industry information under current facts and circumstances. The interpretation of this historical and industry data can be impacted by external forces, principally frequency and severity of future claims, length of time to achieve ultimate settlement of claims, inflation of medical costs and wages, insurance policy coverage interpretations, jury determinations and legislative changes. Accordingly, our reserves may prove to be inadequate to cover our actual losses. If we change our estimates, these changes would be reflected in our results of operations during the period in which they are made, with increases in our reserves resulting in decreases in our earnings.

Acquisitions

First Nonprofit Companies, Inc.

On December 31, 2012, we completed the acquisition of First Nonprofit Companies, Inc. ("FNC") for approximately $55 million. FNC serves approximately 1,500 nonprofit and government entities covering approximately $5 billion of annual payroll. FNC offers unique services as well as insurance programs which are designed to allow nonprofit and government entities to economically manage their unemployment tax obligations. In accordance with FASB ASC 805-10 Business Combinations, the Company recorded a purchase price of approximately $55 million, which consisted primarily of goodwill and intangible assets of $28.2 million and $40.5 million, respectively. The intangible assets consist of customer relationships and have a life of 18 years. The goodwill and intangibles are included as a component of the Small Commercial Business segment. The acquisition of FNC had no impact on the Company's results of operations for 2012.

AHL

During 2012 and 2011, AmTrust Holdings Luxembourg S.A.R.L ("AHL") completed a series of acquisitions described below. AHL is a holding company that purchases Luxembourg captive insurance entities that allows us to obtain the benefit of the captives' capital and utilization of their existing and future loss reserves through a series of reinsurance arrangements with one of our subsidiaries. AHL and the result of our utilization of the captives' loss reserves are included in our Specialty Risk and Extended Warranty segment.

In December 2012, AHL acquired all the issued and outstanding stock of Inter Re S.A., a Luxembourg domiciled captive insurance company, from USG People. The purchase price of Inter Re S.A. was approximately $40.6 million. We recorded approximately $44.8 million of cash, intangible assets of $8.5 million and a deferred tax liability of $12.7 million.

Vandermoortele International Reinsurance Company SA subsequently changed its name to AmTrust Re Zeta.

In June 2011, AHL acquired all the issued and outstanding stock of International Crédit Mutuel Reinsurance SA ("ICM Re"), a Luxembourg domiciled captive insurance company, from Assurance du Credit Mutuel IARD SA.

ICM Re subsequently changed its name to AmTrust Re Alpha.

CNH Capital's Insurance Agencies

In July 2012, we completed the acquisition of CNH Capital Insurance Agency Inc. and CNH Capital Canada Insurance Agency, Ltd., collectively known as "CNH Capital Insurance Agencies," from CNH Capital, the financial services business of CNH Global N.V. The acquisition allows us to enhance and expand CNH Capital Insurance Agencies' offering of equipment extended service contracts and other insurance products to Case IH, Case Construction, New Holland Agriculture and New Holland Construction equipment dealers in the United States and Canada. Additionally, we entered into service and license agreements with CNH Capital whereby we will make future payments based on gross revenues of the CNH Capital Insurance Agencies. In accordance with FASB ASC 805, Business Combinations, we recorded a purchase price of $34 million, which consisted primarily of goodwill and intangible assets of approximately $21.3 million and $19.4 million, respectively. The intangible assets consist of renewal rights and licenses and have asset lives of between 5 and 10 years and are included in our Specialty Risk and Extended Warranty segment. As a result of this transaction, we recorded approximately $10 million of fee income during the year ended December 31, 2012. Additionally, we recorded approximately $30 million of written premium for the year ended December 31, 2012 related to CNH.

BTIS

In December 2011, we acquired the California-based Builders & Tradesmen's Insurance Services, Inc. ("BTIS"), an insurance wholesaler and general agent specializing in insurance policies and bonds for small artisan contractors. The purchase agreement required us to make an initial payment of $5 million on the acquisition date and pay future incentives measured primarily on the overall profitability of the business for a period of approximately 4 years. In accordance with FASB ASC 805, Business Combinations, we recorded a purchase price of approximately $47 million, which included goodwill and intangibles of approximately $28.3 million and $29.9 million, respectively. The intangible assets included renewal rights, distribution networks and trademarks. The trademarks were determined to have an indefinite life while the renewal rights and distribution networks were determined to have lives of 11 years and 17 years, respectively. Additionally, we recorded a liability for approximately $2.4 million related to an unfavorable lease assumed in the transaction. BTIS's revenues are included within our Small Commercial Business segment as a component of service and fee income. We recorded approximately $18 million and $2 million of fee revenue as a result of this acquisition for the years ended December 31, 2012 and 2011, respectively. Additionally, we recorded written premium of approximately $70 million for the year ended December 31, 2012 related to BTIS.

Cardinal Comp

In September 2008, we entered into a managing general agency agreement with Cardinal Comp, LLC ("Cardinal Comp"), a workers' compensation managing general agent for which we paid the agency a commission for the placement of insurance policies. The agency operated in eight states and primarily in the state of New York. In September 2011, one of our subsidiaries entered into a renewal rights and asset purchase agreement with Cardinal Comp and Cook Inlet Alternative Risk
LLC. The existing managing general agency agreement entered into in 2008 was terminated as part of the new agreement and will enable us to reduce commissions on written premium generated from the renewal rights agreement. In accordance with FASB ASC 805-10 Business Combinations, we recorded a purchase price of $30.4 million primarily for goodwill and intangible assets consisting of distribution networks, renewal rights and a trademark. The intangible assets have a life of between 2 and 16 years and are included as a component of the Small Commercial Business segment. We recorded approximately $91 million and $84 million of written premium related to Cardinal Comp for the years ended December 31, 2012 and 2011.

Majestic

One of our subsidiaries and the Insurance Commissioner of the State of California, acting solely in the capacity as the statutory conservator (the "Conservator") of Majestic Insurance Company ("Majestic"), entered into a Rehabilitation Agreement that set forth a plan for the rehabilitation of Majestic (the "Rehabilitation Plan") by which we acquired the business of Majestic through a Renewal Rights and Asset Purchase Agreement (the "Purchase Agreement"), and a Loss Portfolio Transfer and Quota Share Reinsurance Agreement (the "Reinsurance Agreement"). On July 1, 2011, one of our subsidiaries entered into the Reinsurance Agreement, which was effective June 1, 2011, and assumed all of Majestic's liability for losses and loss adjustment expenses under workers' compensation insurance policies of approximately $331.7 million on a gross basis (approximately $183.5 million on a net basis), without any aggregate limit, and certain contracts related to Majestic's workers' compensation business, including leases for Majestic's California office space. In addition, we assumed 100% of the unearned premium reserve of approximately $26 million on all in-force Majestic policies. In connection with this transaction, we received approximately $224.5 million of cash and investments, which included $26 million for a reserve deficiency and also included the assignment of Majestic's reinsurance recoverables of approximately $51.7 million. The Reinsurance Agreement also contains a profit sharing provision whereby we will pay Majestic up to 3% of net earned premium related to current

Majestic policies that we renew in the three year period commencing on the closing date should the loss ratio on such policies for the three year period be 65% or less.

In accordance with FASB ASC 944-805 Business Combinations, we are required to adjust to fair value Majestic's loss and LAE reserves by taking the acquired loss reserves recorded and discounting them based on expected reserve payout patterns using a current risk-free rate of interest. This risk free interest rate is then adjusted based on different cash flow scenarios that use different payout and ultimate reserve assumptions deemed to be reasonably possible based upon the inherent uncertainties present in determining the amount and timing of payment of such reserves. The difference between the acquired loss and LAE reserves and the our best estimate of the fair value of such reserves at acquisition date is amortized ratably over the payout period of the acquired loss and LAE reserves. We determined the fair value of the loss reserves to be $329 million. Accordingly, the amortization will be recorded as an expense on our income statement until fully amortized.

In consideration for our assumption of (i) Majestic's losses and loss adjustment expenses under its workers' compensation insurance policies pursuant to the Reinsurance Agreement and (ii) Majestic's leases for its California offices, pursuant to the Purchase Agreement, we acquired the right to offer, quote and solicit the renewals of in-force workers' compensation policies written by Majestic, certain assets required to conduct such business, including intellectual property and information technology, certain fixed assets, and the right to offer employment to Majestic's California-based employees.

As a result of entering into the Purchase Agreement, in accordance with FASB ASC 805 Business Combinations, we recorded $3.9 million of intangible assets related to distribution networks and trademarks. The distribution networks have a life of 13 years and the trademarks have a life of 2 years. Additionally, we recorded a liability for approximately $0.4 million related to an unfavorable lease assumed in the transaction and a liability for approximately $0.8 million related to the above mentioned profit sharing provision. We recorded written premium, which is included in our Small Commercial Business segment, of approximately $104 million and $43 million for the years ended December 31, 2012 and 2011, respectively.

Strategic Investments

Investment in ACAC

During 2010, we completed our strategic investment in American Capital Acquisition Corporation ("ACAC"). We formed ACAC with The Michael Karfunkel 2005 Grantor Retained Annuity Trust (the "Trust") for the purpose of acquiring from GMAC Insurance Holdings, Inc. and Motor Insurance Corporation ("MIC", together with GMAC Insurance Holdings, Inc., "GMACI"), GMACI's U.S. consumer property and casualty insurance business (the "GMACI Business"), a writer of automobile coverages through independent agents in the United States. Its coverages include standard/preferred auto, RVs, non-standard auto and commercial auto. The acquisition included ten statutory insurance companies (the "GMACI Insurers"). Michael Karfunkel, individually, and the Trust own 100% of ACAC's common stock (subject to our conversion rights described below). Michael Karfunkel is the chairman of our board of directors and the father-in-law of Barry D. Zyskind, our chief executive officer. The ultimate beneficiaries of the Trust include Michael Karfunkel's children, one of whom is married to Mr. Zyskind. In addition, Michael Karfunkel is the Chairman of the Board of Directors of ACAC.

Pursuant to the Amended Stock Purchase Agreement, ACAC issued and sold to us for an initial purchase price of approximately $53 million, which was equal to 25% of the capital initially required by ACAC, 53,054,000 shares of Series A Preferred Stock, which provides an 8% cumulative dividend, is non-redeemable and is convertible, at our option, into 21.25% of the issued and outstanding common stock of ACAC (the "Preferred Stock"). We have pre-emptive rights with respect to any future issuances of securities by ACAC and our conversion rights are subject to customary anti-dilution protections. We have the right to appoint two members of ACAC's board of directors, which consists of six members. Subject to certain limitations, the board of directors of ACAC may not take any action at a meeting without at least one of our appointees in attendance and ACAC may not take certain corporate actions without the approval of a majority of its board of directors (including both of our appointees).

We, the Trust and Michael Karfunkel, individually, each will be required to make its or his proportionate share of deferred payments payable by ACAC to GMACI pursuant to the GMACI Securities Purchase Agreement, the final payment of which is payable March 1, 2013, to the extent that ACAC is unable to otherwise provide for such payments. Our proportionate share of such deferred payments will not exceed $7.5 million. In addition, in connection with our investment, ACAC granted us a right of first refusal to purchase or to reinsure commercial auto insurance business acquired from GMACI. In February 2013, our obligation for any remaining deferred payment was eliminated.

In accordance with ASC 323-10-15, Investments-Equity Method and Joint Ventures, we account for our investment in ACAC under the equity method. We recorded $9.3 million, $4.9 million and $24.5 million of income during the years ended December 31, 2012, 2011 and 2010, respectively related to our equity investment in ACAC.

Personal Lines Quota Share

We, effective March 1, 2010, reinsure 10% of the net premiums of the GMACI Business, pursuant to a 50% quota share reinsurance agreement ("Personal Lines Quota Share") among Integon National Insurance Company, lead insurance company on behalf of the GMACI Insurers, as cedent, and the Company, ACP Re, Ltd., a Bermuda reinsurer that is a wholly-owned indirect subsidiary of the Trust, and Maiden Insurance Company, Ltd., as reinsurers. The Personal Lines Quota Share provides that the reinsurers, severally, in accordance with their participation percentages, receive 50% of the net premium of the GMACI Insurers and assume 50% of the related net losses. We have a 20% participation in the Personal Lines Quota Share, by which we receive 10% of the net premiums of the personal lines business and assume 10% of the related net losses. The Personal Lines Quota Share, which had an initial term of three years, was renewed through March 1, 2016 and will renew automatically for successive three-year terms unless terminated by written notice not less than nine months prior to the expiration of the current term. In addition, either party is entitled to terminate on 60 days' written notice or less upon the occurrence of certain early termination events, which include a default in payment, insolvency, change in control of the Company or the GMACI Insurers, run-off, or a reduction of 50% or more of the shareholders' equity. The GMACI Insurers also may terminate on nine months' written notice following the effective date of an initial public offering or private placement of stock by ACAC or a subsidiary. The Personal Lines Quota Share, as amended on October 1, 2012 provides that the reinsurers pay a provisional ceding commission equal to 32.0% of ceded earned premium, net of premiums ceded by the personal lines companies for inuring reinsurance, subject to adjustment to a maximum of 34.5% if the loss ratio for the reinsured business is 60.0% or less and a minimum of 30.0% if the loss ratio is 64.5% or higher. The Personal Lines Quota Share is subject to a premium cap that limited the premium that could be ceded by the GMACI Insurers to Technology Insurance Company, Inc. ("TIC"), one of our wholly-owned subsidiaries, to $133 million during calendar year 2012 to the extent TIC determined, in good faith, that it could not assume additional premium. The premium cap increases by 10% per annum thereafter. As a result of this agreement, we assumed $118.1 million, $102.6 million and $82.3 million of business from the GMACI Insurers during the years ended December 31, 2012, 2011 and 2010, respectively.

Master Services Agreement

We provide ACAC and its affiliates information technology development services in connection with the development and licensing of a policy management system at a cost which is currently 1.25% of gross written premium of ACAC and its affiliates plus our costs for development and support services. In addition, we provide ACAC and its affiliates printing and mailing services at a per piece cost for policy and policy related materials, such as invoices, quotes, notices and endorsements, associated with the policies we process for ACAC and its affiliates on the policy management system. We recorded approximately $14.4 million, $4.0 million and $2.0 million of fee income for the years ended December 31, 2012, 2011 and 2010, respectively, related to this agreement.

Asset Management Agreement

We manage the assets of ACAC and its subsidiaries for an annual fee equal to 0.20% of the average aggregate value of the assets under management for the preceding quarter if the average aggregate value for the preceding quarter is $1 billion or less and 0.15% of the average aggregate value of the assets under management for the preceding quarter if the average aggregate value for that quarter is more than $1 billion. We currently manage approximately $730 million of assets as of December 31, 2012 related to this agreement. As a result of this . . .
