ARGO Argo Group International Holdings Ltd

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

The accompanying consolidated financial statements of Argo Group International Holdings, Ltd. (“Argo Group,” “we” or the “Company”) and its subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. The preparation of interim 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 reported amounts of revenues and expenses during the reporting period. The major estimates reflected in our consolidated financial statements include, but are not limited to, reserves for losses and loss adjustment expenses; reinsurance recoverables, including the reinsurance recoverables allowance for doubtful accounts; estimates of written and earned premiums; reinsurance premium receivable; fair value of investments and assessment of potential impairment; valuation of goodwill and intangibles and our deferred tax asset valuation allowance. Actual results could differ from those estimates. Certain financial information that normally is included in annual financial statements, including certain financial statement footnotes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016, filed with the Securities and Exchange Commission on February 24, 2017.

Effective February 6, 2017, we completed the acquisition of Maybrooke Holdings, S.A. (“Maybrooke”) and its direct subsidiaries, including Ariel Re. We have accounted for the acquisition in accordance with Accounting Standards Codification (“ASC”) 805, “Business Combinations,” and the purchase price has been preliminarily allocated to the assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. See Note 3, “Acquisition of Maybrooke,” for additional discussion regarding the acquisition and the related financial disclosures. The Consolidated Financial Statements as of and for the three months ended March 31, 2017 and the Notes to the Consolidated Financial Statements reflect the consolidated results of Argo Group and Maybrooke commencing on the date of acquisition.

The interim financial information as of, and for the three months ended, March 31, 2017 and 2016 is unaudited. However, in the opinion of management, the interim information includes all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the results presented for the interim periods. The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year. All significant intercompany amounts have been eliminated in consolidation.

During the first quarter of 2017, we evaluated and modified the presentation of our reportable segments to better reflect our new operating framework and management structure. Under this model, Argo Group’s chief operating decision maker – Mark E. Watson III, President and Chief Executive Officer – evaluates performance and allocates resources based on the review of the U.S. Operations and the International Operations. The U.S. Operations includes the former Excess & Surplus and Commercial Specialty reportable segments. The International Operations includes the former Syndicate 1200, International Specialty reportable segments, and the recently acquired Ariel Re business. (See Note 3, “Acquisition of Maybrooke” for details regarding Ariel Re.) The business unit that produces the risk and not the location of the underlying exposure is the primary characteristic in distinguishing operating and reportable segments. For example, a U.S. property exposure underwritten through our Syndicate platform would be included in International Operations. Consistent with prior periods, the Run-off Lines and Corporate segments include all other activity of Argo Group and are included in our consolidated financial results. Segment results for the three months ended March 31, 2016 have been reclassified to conform to the current presentation.

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-01, “Business Combination” (Topic 805). ASU 2017-01 clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance specifies the minimum inputs and processes required to meet the definition of a business. The guidance is effective for annual periods beginning after December 15, 2017, and interim periods within those periods, with early adoption permitted. We do not anticipate that this ASU will have a material impact on our financial results or disclosures.

In January 2017, the FASB issued ASU 2017-04, “ Intangibles – Goodwill and Other ” (Topic 350). ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill that is done in Step 2 of the current goodwill impairment test to measure a goodwill impairment loss. Instead, entities will record an impairment loss based on the excess of a reporting unit’s carrying amount over its fair va lue . The guidance will be applied prospectively and is effective for annual and interim impairment tests performed in period s beginning after December 15, 2019 . E arly adoption is permitted for annual and interim goodwill impairment testing dates after Janu ary 1, 2017. We do not anticipate that this ASU will have a material impact on our financial results or disclosures.

In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments (Topic 230). ASU 2016-15 will reduce diversity in practice on how eight specific cash receipts and payments are classified on the statement of cash flows. The ASU will be effective for fiscal years beginning after December 15, 2017, including interim periods within those years. This ASU will have an impact on how we present the distributions received from equity method investees in our statement of cash flows. We have elected to adopt the cumulative earnings approach to classify distributions received from equity method investees, which we will adopt retrospectively. We anticipate that this ASU will have no net effect on our consolidated statements of cash flows, but will likely have an immaterial impact on the reclassification of specific cash receipts and payments within the statement.

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments” (Topic 326). ASU 2016-13 requires organizations to estimate credit losses on certain types of financial instruments, including receivables and available-for-sale debt securities, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance requires a modified retrospective transition method and early adoption is permitted. We are currently evaluating the impact that the adoption of the ASU will have on our financial results and disclosures, but do not anticipate that any such potential impact would be material.

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” (Topic 718). ASU 2016-09 simplifies the accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows, and accounting for forfeitures. The ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. We have adopted this ASU as of January 1, 2017, and for presentation purposes, the incremental tax windfall or shortfall associated with these events will be classified as a cash inflow from operating activity as compared with a financing activity, as previously required. The impact to our financial statements was not material. Additionally, we have selected to continue estimating forfeitures based on historical patterns and will true-up the expenses upon vesting.

In February 2016, the FASB issued ASU 2016-02, “Leases” (Topic 842). ASU 2016-02 requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additionally, the ASU modifies current guidance for lessors' accounting. The ASU is effective for interim and annual reporting periods beginning on or after January 1, 2019, with early adoption permitted. We do not anticipate that this ASU will have a material impact on our results of operations, but we anticipate an increase to the value of our assets and liabilities related to leases, with no material impact to equity.

In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (Subtopic 825-10). ASU 2016-01 will require equity investments that are not consolidated or accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net income. This ASU will also require us to assess the ability to realize our deferred tax assets (“DTAs”) related to an available-for-sale debt security in combination with our other DTAs. The ASU will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. While we continue to evaluate the impact of this ASU, we anticipate the standard will increase the volatility of our consolidated statements of income, resulting from the remeasurement of our equity investments.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” (Topic 606), which replaces most existing U.S. GAAP revenue recognition guidance and permits the use of either the retrospective or cumulative effect transition method. In August 2015, “Deferral of the Effective Date” (Topic 606), deferred the effective date of this guidance to interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016. Subsequently, in 2016, the FASB issued implementation guidance related to ASU 2014-09, including:

While insurance contracts are excluded from this ASU, fee income related to our brokerage operations and management of the third-party capital for our underwriting Syndicate at Lloyd’s will be subject to this updated guidance. We continue to evaluate what impact this ASU will have on our financial results and disclosures and which adoption method to apply, but do not anticipate such impact being material based on the limited revenue streams subject to the ASU.

Effective February 6, 2017, we completed the acquisition of Maybrooke whereby we acquired all of the issued and outstanding capital stock of Maybrooke. The initial purchase price of $235.3 million was paid in cash from funds on hand and available under our credit facility (see Note 7, “Other Indebtedness”). The initial purchase price is subject to post-closing adjustments based on a final calculation of the purchase price, to be delivered to the seller within 90 days of closing.

Through the acquisition of Maybrooke, we acquired Ariel Re, a global underwriter of specialty insurance and reinsurance business written primarily through its Lloyd’s Syndicate 1910. Ariel Re provides Argo Group with a number of strategic advantages, including enhanced scale in its London- and Bermuda-based platforms.

The acquisition is being accounting for in accordance with ASC 805, “Business Combinations.” Purchase accounting, as defined by ASC 805, requires that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. We are in the process of finalizing our determination of fair values, including an independent appraisal of certain assets and liabilities, including intangible assets. Therefore, a preliminarily allocation of the purchase price to the acquired assets, liabilities, and intangible assets is presented in the table below:

The fair value measurement period will continue into the second quarter of 2017, during which time we expect to finalize the valuation analyses. The excess of the purchase price over the fair value of the net assets acquired has been preliminarily allocate d to intangible assets, which will be specifically identified and quantified during the second quarter of 2017. We did not record amortization expense related to the $40.4 million intangible assets during the first quarter of 2017 due to the intangible ass ets having not yet been specifically identified. We anticipate recording both amortizable and non-amortizable identifiable intangible assets and goodwill upon the completion of the valuation analyses, including intangible assets relating to the Lloyd’s Syn dicate 1910 stamp capacity (non- amortizable), distribution networks (amortizable), and the Ariel Re tradename (amortizable). G oodwill is calculated as the excess of the purchase price over the fair value of the net assets recognized, including identifiable intangible assets.

We recognized approximately $2.5 million of transaction costs in the first quarter of 2017 related to the acquisition in our Consolidated Statements of Income, of which $2.2 million were reported in “Underwriting, acquisition and insurance expenses” and $0.3 million in “Interest expense” related to the borrowings under our credit facility to help fund the acquisition.

Maybrooke’s Contribution to Argo Group’s Revenue and Income

The following selected financial information summarizes the results of Maybrooke from the date of acquisition that have been included in our Consolidated Statement of Income:

Unaudited Pro forma Results of Operations

The following unaudited pro forma financial information has been provided to present a summary of the combined results of Argo Group’s operations with Maybrooke’s as if the acquisition had occurred on January 1, 2016. The unaudited pro forma financial information is for informational purposes only and is not necessarily indicative of what the results would have been had the acquisition been completed at the date indicated above, as it may not include all necessary adjustments. Future changes to Maybrooke’s business, such as, but not limited to, the impact from underwriting decisions, changes in risk selection, or retention rates, could result in a material favorable or unfavorable impact on Argo Group’s future results of operations and financial position. The unaudited pro forma results for three months ended March 31, 2017 include favorable development from prior accident years of $6.7 million, including $6.2 million relating to one specific claim in January 2017. In addition, the $2.5 million of nonrecurring transaction costs directly attributable to the acquisition, as disclosed above, have also been removed from the unaudited pro forma results for the three months ended March 31, 2017 in the table below. The unaudited pro forma results for the three months ended March 31, 2016 include the benefits of higher net retention resulting in increased earned premiums and profitability for prior Lloyd’s years of account, partially offset by unfavorable development on claims from prior accident years.

Included in “Total investments” in our Consolidated Balance Sheets at March 31, 2017 and December 31, 2016 is $154.0 million and $131.9 million, respectively, of assets managed on behalf of the trade capital providers, who are third-party participants that provide underwriting capital to the operations of Syndicate 1200.

The expected maturities may differ from the contractual maturities because debtors may have the right to call or prepay obligations.

The following describes each investment type:

We regularly evaluate our investments for other-than-temporary impairment. For fixed maturity securities, the evaluation for a credit loss is generally based on the present value of expected cash flows of the security as compared to the amortized book value. For structured securities, frequency and severity of loss inputs are used in projecting future cash flows of the securities. Loss frequency is measured as the credit default rate, which includes such factors as loan-to-value ratios and credit scores of borrowers. For equity securities and other investments, the length of time and the amount of decline in fair value are the principal factors in determining other-than-temporary impairment. We also recognize other-than-temporary losses on fixed maturity securities that we intend to sell.

We hold a total of 7,909 securities, of which 2,035 were in an unrealized loss position for less than one year and 149 were in an unrealized loss position for a period one year or greater as of March 31, 2017. Unrealized losses greater than twelve months on fixed maturities were the result of a number of factors, including increased credit spreads, foreign currency fluctuations and higher market yields relative to the date the securities were purchased, and for structured securities, by the performance of the underlying collateral,

as well. In considering whether an investment is other-than-temporarily impaired or not, we also considered that we do not intend to sell the investments and it is unlikely that we will be required to sell the investments before recovery of their amortized cost bases, which may be maturity. In situations where we did not recognize other-than-temporary losses on investments in our equity portfoli o, we have evaluated the near-term prospects of the investment in relation to the severity and duration of the impairment and based on that evaluation, have the ability and intent to hold these investments until a recovery of the cost basis. We do not cons ider these investments to be other-than-temporarily impaired at March 31, 2017.

We recognized other-than-temporary losses on our fixed maturities and equity portfolio as follows:

The cost of securities sold is based on the specific identification method.

Changes in unrealized appreciation (depreciation) related to investments are summarized as follows:
