Basis of Presentation Basis of Presentation
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, 2018, filed with the Securities and Exchange Commission on February 25, 2019.
The interim financial information as of, and for the three and six months ended June 30, 2019 and 2018 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. Certain reclassifications have been made to financial information presented for prior years to conform to the current year’s presentation.

Recently Issued Accounting Pronouncements Recently Issued Accounting Pronouncements
In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2018-13, "Fair Value Measurement" (Topic 820). ASU 2018-13 eliminates, adds and modifies certain disclosure requirements on fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within the year of adoption. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are applied prospectively for only the most recent interim or annual period presented in the initial fiscal year adoption. All other amendments are applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. We are currently in the process of evaluating the impact that the adoption of the ASU will have on our financial disclosures.
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 the year of adoption. The guidance requires a modified retrospective transition method and early adoption is permitted. We are currently in the process of evaluating the impact that the adoption of the ASU will have on our financial results and disclosures.
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. In July 2018, the FASB issued ASU 2018-11, "Leases: Targeted Improvements" (Topic 842), which provides for an alternative transition method by allowing entities to initially apply the new leases standard at the adoption date (such as January 1, 2019) and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption (comparative periods presented in the financial statements will continue to be in accordance with current GAAP (Topic 840, Leases). The standard was effective for annual and interim periods beginning after December 15, 2018, with earlier application permitted.
We have entered into operating leases for office space and certain other assets. We adopted the new standard on the effective date of January 1, 2019. We applied the following practical expedients:
We have elected to adopt this standard using the option transition method, which allows companies to continue applying the guidance under the lease standard in effect at that time in the comparative periods presented in the consolidated financial statements. The adoption of the standard had no effect on our consolidated shareholders’ equity. Prior periods were not restated.
We have elected the "package of practical expedients", which permits us not to reassess under the new standard our prior conclusion about lease identification, lease classification and initial direct costs.
Where we are the lessor, we have elected the practical expedient which permits us to not separate non-lease components from the associated lease components if the non-lease components otherwise would be accounted for in accordance with the new revenue standard.
For the majority of our asset classes, we elected not to separate lease and non-lease components. As a result, our right-of-use assets and lease liabilities represent base rent components of our leases. We have elected to not apply the practical expedient which allows the use of hindsight in determining the lease term and in assessing impairment of the entity’s right-of-use assets. The remaining practical expedients did not specifically apply to our lease population as of the adoption date.
Please see Note 4 - “Leases” for further discussion on the impact of the adoption of this standard.

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. We also recognize other-than-temporary losses on fixed maturity securities that we intend to sell. Effective January 1, 2018, the Company adopted ASU 2016-01. As a result, changes in the fair value of equity securities are recognized in net realized investment gains in the Consolidated Statement of Income.
We hold a total of 9,406 securities, of which 1,122 were in an unrealized loss position for less than one year and 832 were in an unrealized loss position for a period one year or greater as of June 30, 2019. 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 or not an investment is other-than-temporarily impaired, 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. We do not consider these investments to be other-than-temporarily impaired at June 30, 2019.
We recognized other-than-temporary losses on our fixed maturities portfolio as follows:

Foreign Currency Exchange Forward Contracts
We entered into foreign currency exchange forward contracts to manage operational currency exposure on our Canadian dollar investment portfolio, minimize negative impacts to investment portfolio returns, and gain exposure to a total return strategy which invests in multiple currencies.  The currency forward contracts are carried at fair value in our Consolidated Balance Sheets in “Other liabilities.” The gains and losses are included in “Net realized investment gains (losses)” in our Consolidated Statements of Income.
The fair value of our foreign currency exchange forward contracts as of June 30, 2019 and December 31, 2018 was as follows:

Fair Value Measurements
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability, or in the absence of a principal market, the most advantageous market. Market participants are buyers and sellers in the principal (or most advantageous) market that are independent, knowledgeable, able to transact for the asset or liability and willing to transfer the asset or liability.
Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. The inputs of these valuation techniques are categorized into three levels.
Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that can be accessed at the reporting date. We define actively traded as a security that has traded in the past seven days. We receive one quote per instrument for Level 1 inputs.
Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. We receive one quote per instrument for Level 2 inputs.
Level 3 inputs are unobservable inputs. Unobservable inputs reflect our own judgments about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances.
We receive fair value prices from third-party pricing services and our outside investment managers. These prices are determined using observable market information such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. We have reviewed the processes used by the third-party providers for pricing the securities, and have determined that these processes result in fair values consistent with GAAP requirements. In addition, we review these prices for reasonableness, and have not adjusted any prices received from the third-party providers as of June 30, 2019 and December 31,2018. A description of the valuation techniques we use to measure assets at fair value is as follows:
Fixed Maturities (Available-for-Sale) Levels 1 and 2:
United States Treasury securities are typically valued using Level 1 inputs. For these securities, we obtain fair value measurements from third-party pricing services using quoted prices (unadjusted) in active markets at the reporting date.
United States Government agencies, non-U.S. Government securities, obligations of states and political subdivisions, credit securities and foreign denominated government and credit securities are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, yield curves, live trading levels, trade execution data, credit information and the security’s terms and conditions, among other things.
Asset and mortgage-backed securities and collateralized loan obligations are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things.
Fixed Maturities (Available-for-Sale) Levels 3:
We own term loans that are valued using unobservable inputs.
Equity Securities Level 1: Equity securities are principally reported at fair value using Level 1 inputs. For these securities, we obtain fair value measurements from a third-party pricing service using quoted prices (unadjusted) in active markets at the reporting date.
Equity Securities Level 3: We own certain equity securities that are reported at fair value using Level 3 inputs. The valuation techniques for these securities include the following:
Fair value measurements for an investment in an equity fund obtained by applying final prices provided by the administrator of the fund, which is based upon certain estimates and assumptions.
Fair value measurements from a broker and an independent valuation service, both based upon estimates and assumptions.
Other Investments Level 2: Foreign regulatory deposits are assets held in trust in jurisdictions where there is a legal and regulatory requirement to maintain funds locally in order to protect policyholders. Lloyd’s is the appointed investment manager for the funds. These assets are invested in short-term government securities, agency securities and corporate bonds and are valued using Level 2 inputs based upon values obtained from Lloyd’s.
Short-term Investments: Short-term investments are principally reported at fair value using Level 1 inputs, with the exception of short-term corporate and governmental bonds reported at fair value using Level 2 inputs as described in the fixed maturities section above. Values for the investments categorized as Level 1 are obtained from various financial institutions as of the reporting date.
Transfers Between Level 1 and Level 2 Securities: There were no transfers between Level 1 and Level 2 securities during the six months ended June 30, 2019.
Based on an analysis of the inputs, our financial assets measured at fair value on a recurring basis have been categorized as follows:

Leases [Abstract]  
Leases Leases
We adopted ASU 2016-02, "Leases" on January 1, 2019, which resulted in the recognition of operating leases on the balance sheet beginning in 2019 and forward. See Note 2, “Recently Issued Accounting Pronouncements,” for additional information on the adoption of the ASU.
We determine if a contract contains a lease at inception and recognize operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments at the commencement date. As our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at the commencement date to determine the present value of future payments. Lease agreements have lease and non-lease components. We account for these components separately, therefore our operating lease right-of-use asset and operating lease liabilities represent base rent only. Lease expense is recognized on a straight-line basis over the lease term.
Our operating lease obligations are for office facilities, corporate housing, and equipment, including corporate aviation. Our leases have remaining lease terms of less than 1 year to 14 years, some of which include options to extend the leases. Expenses associated with leases totaled $6.1 million and $12.2 million for the three and six months ended June 30, 2019, respectively as compared to $5.0 million and $9.7 million for the three and six months ended June 30, 2018. The components of lease expense and other lease information as of and during the six months ended June 30, 2019 are as follows:

We have certain investment properties that we lease to independent, third parties. These properties consist of an office building that is currently leased through August 2026 and three condominiums that are leased on a short-term basis. The carrying value of these assets are included in "Other assets" on our consolidated balance sheet. Income for these leased properties was $0.7 million for each of the three months ended June 30, 2019 and 2018, and $1.5 million for each of the six months ended June 30, 2019 and 2018. Income for these leased properties are included in "Fee and other income" on our consolidated statements of income.

Reserves for losses and LAE represent the estimated indemnity cost and related adjustment expenses necessary to investigate and settle claims. Such estimates are based upon individual case estimates for reported claims, estimates from ceding companies for reinsurance assumed and actuarial estimates for losses that have been incurred but not yet reported to the insurer. Any change in probable ultimate liabilities is reflected in current operating results.

The following describes the primary factors behind each segment’s prior accident year reserve development for the six months ended June 30, 2019 and 2018:
Six months ended June 30, 2019:
U.S. Operations: Favorable development in general liability and surety lines, partially offset by unfavorable development in property and commercial multi-peril lines.
International Operations: Unfavorable development was primarily related to certain liability, property and specialty lines. The liability charges included public utility business in our Bermuda casualty division, which we previously exited, and to a lesser extent our European and Syndicate 1200 operations. As it relates to Europe, the adverse development primarily related to certain cover-holders whose contracts were previously terminated. As it relates to Syndicate 1200, the adverse development related to businesses that we have previously exited or where aggressive remedial underwriting actions have been taken.
The International Operations unfavorable development includes $26.4 million recognized during the second quarter of 2019. The timing of recognizing this unfavorable development was primarily due to obtaining additional information on several individual claims, including reports provided by outside counsel, audits of the underlying losses and recent jury awards. The result was an increase in the number of claims with the potential for underlying losses to reach our attachment point, particularly on aggregate treaty contracts within our Bermuda Operations. The second quarter 2019 unfavorable development was also attributable to the results of recent audits, underwriting reviews, and updated data from third party cover-holders, which included the identification of differences from original expectations with regard to the classes written, the distribution of writings by geography, and the rates charged by the cover-holders.
Run-off Lines: Unfavorable development in other run-off lines, partially offset by favorable development in risk management workers compensation.
Six months ended June 30, 2018:
U.S. Operations: Favorable development in liability and surety lines, partially offset by unfavorable development in commercial multi-peril lines.
International Operations: Favorable development in property lines, partially offset by unfavorable development within specialty lines.
Run-off Lines: Unfavorable development in risk management lines and other run-off lines.
In the opinion of management, our reserves represent the best estimate of our ultimate liabilities, based on currently known facts, current law, current technology and assumptions considered reasonable where facts are not known. Due to the significant uncertainties and related management judgments, there can be no assurance that future favorable or unfavorable loss development, which may be material, will not occur.

On February 20, 2018, the Board of Directors declared a 15% stock dividend, payable March 21, 2018 to all shareholders of record at the close of business on March 7, 2018. As a result of the stock dividend, 4,397,520 additional shares were issued. Cash was paid in lieu of fractional shares of our common shares. Excluding repurchased shares, all references to common shares and related per share amounts in this document and related disclosures have been adjusted to reflect the stock dividend for all periods presented.
On May 3, 2016, our Board of Directors authorized the repurchase of up to $150.0 million of our common shares (“2016 Repurchase Authorization”). The 2016 Repurchase Authorization supersedes all previous Repurchase Authorizations. As of June 30, 2019, availability under the 2016 Repurchase Authorization for future repurchases of our common shares was $53.3 million.
We did not repurchase any common shares for the six months ended June 30, 2019.

Share-based Compensation

Share-based Payment Arrangement [Abstract]  
Share-based Compensation Share-based Compensation
The fair value method of accounting is used for share-based compensation plans. Under the fair value method, compensation cost is measured based on the fair value of the award at the measurement date and recognized over the requisite service period. We use the Black-Scholes model to estimate the fair values on the measurement date for share options and share appreciation rights (“SARs”). The Black-Scholes model uses several assumptions to value a share award. The risk-free rate of return assumption is based on the five-year U.S. Treasury constant maturity rate on the measurement date. The expected dividend yield is based on our history and expected dividend payouts. The expected award life is based upon the average holding period over the history of the incentive plan. The expected volatility assumption is based on the historical change in our stock price over the previous five years preceding the measurement date.
The following table summarizes the assumptions we used for the six months ended June 30, 2019 and 2018:

Argo Group’s 2019 Omnibus Incentive Plan
In May 2019, our shareholders approved the 2019 Omnibus Incentive Plan (the “2019 Plan”), which provides equity-based and cash-based performance-related incentives to key employees, non-employee directors and other service providers. The intent of the 2019 Plan is to encourage and provide for the acquisition of an ownership interest in Argo Group, enabling us to attract and retain qualified and competent persons to serve as members of a management team and the Board of Directors. The 2019 Plan authorizes 1,885,000 shares of common stock to be granted as equity-based awards. All awards granted after December 31, 2018 will be issued under the 2019 Plan. No further grants will be made under any prior plan; however, any awards under a prior plan that are outstanding as of the effective date shall remain subject to the terms and conditions of, and be governed by, such prior plan.
Awards granted under the 2019 Plan may be in the form of stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards, other stock-based awards or other cash-based awards. Awards may be granted either alone or in addition to or in tandem with other awards authorized under the 2019 Plan. Awards that settled in stock will count as one share for the purposes reducing the share reserve under the 2019 Plan. Shares issued under this plan may be shares that are authorized and unissued or shares that we reacquired, including shares purchased on the open market.
Stock options and stock appreciation rights are required to have an exercise that is not less than the fair market value on the date of grant. The term of these awards is not to exceed ten years.

General expenses in the table above include $7.5 million and $8.0 million of expenses associated with proxy solicitation and related activities for the three and six months ended June 30, 2019, respectively. Given the unique and non-recurring nature of the events that gave rise to these expenses, these costs are not included in the calculation of our expense and combined ratios. There were no comparable costs incurred for the three and six months ended June 30, 2018.

Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
We are incorporated under the laws of Bermuda and, under current Bermuda law, are not obligated to pay any taxes in Bermuda based upon income or capital gains. We have received an undertaking from the Supervisor of Insurance in Bermuda pursuant to the provisions of the Exempted Undertakings Tax Protection Act, 2011, which exempts us from any Bermuda taxes computed on profits, income or any capital asset, gain or appreciation or any tax in the nature of estate, duty or inheritance tax, at least until the year 2035.
We do not consider ourselves to be engaged in a trade or business in the United States or the United Kingdom and, accordingly, do not expect to be subject to direct United States or United Kingdom income taxation.
We have subsidiaries based in the United Kingdom that are subject to the tax laws of that country. Under current law, these subsidiaries are taxed at the applicable corporate tax rates. Eight of the United Kingdom subsidiaries are deemed to be engaged in business in the United States, and therefore, are subject to United States corporate tax in respect of a proportion of their United States underwriting business only. Relief is available against the United Kingdom tax liabilities in respect of overseas taxes paid that arise from the underwriting business. Our United Kingdom subsidiaries file separate United Kingdom income tax returns.
We have subsidiaries based in the United States that are subject to United States tax laws. Under current law, these subsidiaries are taxed at the applicable corporate tax rates. Our United States subsidiaries generally file a consolidated United States federal income tax return.
We also have operations in Belgium, Brazil, France, Ireland, Italy, Malta, Spain, and Switzerland, which also are subject to income taxes imposed by the jurisdiction in which they operate. We have operations in Barbados and the United Arab Emirates, which are not subject to income tax under the laws of those countries.
Our expected income tax provision computed on pre-tax income (loss) at the weighted average tax rate has been calculated as the sum of the pre-tax income (loss) in each jurisdiction multiplied by that jurisdiction’s applicable statutory tax rate. For the three and six months ended June 30, 2019 and 2018, pre-tax income (loss) attributable to our operations and the operations’ effective tax rates were as follows:

Our effective tax rate may vary significantly from period to period depending on the jurisdiction generating the pre-tax income (loss) and its corresponding statutory tax rate. The geographic distribution of pre-tax income (loss) can fluctuate significantly between periods given the inherit nature of our business. A reconciliation of the difference between the provision for income taxes and the expected tax provision at the weighted average tax rate is as follows:

(1) Tax effect of the adjustment for the respective year was less than $0.1 million.

Our gross deferred tax assets are supported by taxes paid in previous periods, reversal of taxable temporary differences and recognition of future taxable income. Management regularly evaluates the recoverability of the deferred tax assets and makes any necessary adjustments to them based upon any changes in management’s expectations of future taxable income. Realization of deferred tax assets is dependent upon our generation of future taxable income sufficient to recover tax benefits that cannot be recovered from taxes paid in the carryback period, generally for our US property and casualty insurers two years for net operating losses and for all our US subsidiaries three years for capital losses. If a company determines that any of its deferred tax assets will not result in future tax benefits, a valuation allowance must be established for the portion of these assets that are not expected to be realized. The net change in valuation allowance for deferred tax assets was a decrease of $0.6 million in 2019 relating to the following: Internal Revenue Code Section 382 limited net operating loss carryforwards within the United States, cumulative losses incurred since inception, and valuation allowances acquired through or related to acquisitions. Based upon a review of our available evidence, both positive and negative discussed above, our management concluded that it is more-likely-than-not that the other deferred tax assets will be realized.
For any uncertain tax positions not meeting the “more-likely-than-not” recognition threshold, accounting standards require recognition, measurement and disclosure in a company’s financial statements. We had no material unrecognized tax benefits as of June 30, 2019 and 2018. Our United States subsidiaries are no longer subject to U.S. federal and state income tax examinations by tax authorities for years before 2015. Our United Kingdom subsidiaries are no longer subject to United Kingdom income tax examinations by Her Majesty’s Revenue and Customs for years before 2017.

Segment Reporting [Abstract]  
Segment Information Segment Information
We are primarily engaged in underwriting property and casualty insurance and reinsurance. We have two ongoing reporting segments: U.S. Operations and International Operations. Additionally, we have a Run-off Lines segment for certain products that we no longer underwrite.
We consider many factors, including the nature of each segment’s insurance and reinsurance products, production sources, distribution strategies and the regulatory environment, in determining how to aggregate reporting segments. Transactions between segments are reported in the segment that initiated the transaction.
In evaluating the operating performance of our segments, we focus on core underwriting and investing results before the consideration of realized gains or losses from investments. Realized investment gains are reported as a component of the Corporate and Other segment, as decisions regarding the acquisition and disposal of securities reside with the corporate investment function and are not under the control of the individual business segments. Identifiable assets by segment are those assets used in the operation of each segment.
Revenue and income before income taxes for each segment were as follows:

Debt Disclosure [Abstract]  
Senior Unsecured Fixed Rate Notes Senior Unsecured Fixed Rate Notes 
In September 2012, Argo Group (the “Parent Guarantor”), through its subsidiary Argo Group US (the “Subsidiary Issuer”), issued $143,750,000 aggregate principal amount of the Subsidiary Issuer’s 6.5% Senior Notes due September 15, 2042 (the “Notes”). The Notes are unsecured and unsubordinated obligations of the Subsidiary Issuer and rank equally in right of payment with all of the Subsidiary Issuer’s other unsecured and unsubordinated debt. The Notes are guaranteed on a full and unconditional senior unsecured basis by the Parent Guarantor. The Notes may be redeemed, for cash, in whole or in part, on or after September 15, 2017, at the Subsidiary Issuer’s option, at any time and from time to time, prior to maturity at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued but unpaid interest on the principal amount being redeemed to, but not including, the redemption date.
In accordance with ASC 835-30, “Interest-Imputation of Interest” we present the unamortized debt issuance costs in the balance sheet as a direct deduction from the carrying value of the debt liability. At June 30, 2019 and December 31, 2018, the Notes consisted of the following:

Basis of Presentation (Policies)

Accounting Policies [Abstract]  
Basis of Presentation
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, 2018, filed with the Securities and Exchange Commission on February 25, 2019.
The interim financial information as of, and for the three and six months ended June 30, 2019 and 2018 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.
Reclassification Certain reclassifications have been made to financial information presented for prior years to conform to the current year’s presentation.
Recently Issued Accounting Pronouncements
In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2018-13, "Fair Value Measurement" (Topic 820). ASU 2018-13 eliminates, adds and modifies certain disclosure requirements on fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within the year of adoption. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are applied prospectively for only the most recent interim or annual period presented in the initial fiscal year adoption. All other amendments are applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. We are currently in the process of evaluating the impact that the adoption of the ASU will have on our financial disclosures.
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 the year of adoption. The guidance requires a modified retrospective transition method and early adoption is permitted. We are currently in the process of evaluating the impact that the adoption of the ASU will have on our financial results and disclosures.
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. In July 2018, the FASB issued ASU 2018-11, "Leases: Targeted Improvements" (Topic 842), which provides for an alternative transition method by allowing entities to initially apply the new leases standard at the adoption date (such as January 1, 2019) and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption (comparative periods presented in the financial statements will continue to be in accordance with current GAAP (Topic 840, Leases). The standard was effective for annual and interim periods beginning after December 15, 2018, with earlier application permitted.
We have entered into operating leases for office space and certain other assets. We adopted the new standard on the effective date of January 1, 2019. We applied the following practical expedients:
We have elected to adopt this standard using the option transition method, which allows companies to continue applying the guidance under the lease standard in effect at that time in the comparative periods presented in the consolidated financial statements. The adoption of the standard had no effect on our consolidated shareholders’ equity. Prior periods were not restated.
We have elected the "package of practical expedients", which permits us not to reassess under the new standard our prior conclusion about lease identification, lease classification and initial direct costs.
Where we are the lessor, we have elected the practical expedient which permits us to not separate non-lease components from the associated lease components if the non-lease components otherwise would be accounted for in accordance with the new revenue standard.
For the majority of our asset classes, we elected not to separate lease and non-lease components. As a result, our right-of-use assets and lease liabilities represent base rent components of our leases. We have elected to not apply the practical expedient which allows the use of hindsight in determining the lease term and in assessing impairment of the entity’s right-of-use assets. The remaining practical expedients did not specifically apply to our lease population as of the adoption date.
Please see Note 4 - “Leases” for further discussion on the impact of the adoption of this standard.
