Accounting Policies [Abstract]
BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION	A. Basis of Presentation and Principles of Consolidation The consolidated financial statements of The Hanover Insurance Group, Inc. (“THG” or the “Company”), include the accounts of The Hanover Insurance Company (“Hanover Insurance”) and Citizens Insurance Company of America (“Citizens”), THG’s principal property and casualty companies; and other insurance and non-insurance subsidiaries. These legal entities conduct their operations through several business segments discussed in Note 13 – “Segment Information.” The consolidated financial statements also include the Company’s discontinued operations, consisting primarily of the Company’s former accident and health and life insurance businesses and its former Chaucer international business, Chaucer Holdings Limited (“Chaucer”), a United Kingdom (“U.K.”) domiciled specialist insurance underwriting group which operates through the Society and Corporation of Lloyd’s (“Lloyd’s”), and other international insurance and non-insurance subsidiaries. All intercompany accounts and transactions have been eliminated. On December 28, 2018, the Company completed the sale of Chaucer to China Reinsurance (Group) Corporation (“China Re”), and subsequently completed the sales of the Chaucer-related Irish and Australian entities on February 14, 2019 and April 10, 2019, respectively. Accordingly, for all prior periods presented in this Annual Report on Form 10-K, operations from Chaucer are presented as discontinued operations. The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) requires the Company 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 the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of the Company’s management these financial statements reflect all adjustments, consisting of normal recurring items, necessary for a fair presentation of the financial position and results of operations.
INVESTMENTS	B. Investments Fixed maturities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses, net of taxes, reported in accumulated other comprehensive income (“AOCI”), a separate component of shareholders’ equity. The amortized cost of fixed maturities is adjusted for amortization of premiums and accretion of discounts to maturity. Equity securities are carried at fair value. Increases and decreases in fair value are reported in net income. Other investments consist primarily of mortgage participations and limited partnerships. Mortgage participations represent interests in commercial mortgage loans originated and serviced by a third-party of which the Company shares, on a pro-rata basis, in all related cash flows of the underlying mortgage loans. Mortgage participations are stated at unpaid principal balances adjusted for deferred fees or expenses, net of an allowance for credit losses. Prior to May 2018, certain reacquisition rights retained by the third-party in the loan participations required that these investments be accounted for as secured borrowings under Accounting Standards Codification (“ASC”) 860, Transfers and Servicing. Investments in limited partnerships include interests in private equity and real estate funds. Investments in limited partnership interests purchased prior to January 1, 2018, where the Company’s interest is so minor that it exercises virtually no influence over operating and financial policies, are accounted for at fair value utilizing the net asset value (“NAV”) as a practical expedient to determine fair value. All other limited partnerships are accounted for in accordance with the equity method of accounting. The Company excludes accrued interest receivable from both the estimated fair value and the amortized cost basis of its investment securities and reports such amounts separately on the consolidated balance sheets as accrued investment income. When accrued interest receivable is deemed uncollectible it is written off as a charge to investment income, rather than recorded through an allowance. Net investment income includes interest, dividends and income from limited partnership interests. Interest income is recognized based on the effective yield method, which includes the amortization of premiums and accretion of discounts. The effective yield used to determine the amortization for fixed maturities subject to prepayment risk, such as mortgage-backed and asset-backed securities, is recalculated and adjusted periodically based upon actual historical and projected future cash flows. The adjustment to yields for highly rated prepayable fixed maturities is accounted for using the retrospective method. The adjustment to yields for all other prepayable fixed maturities is accounted for using the prospective method. Fixed maturities and mortgage participations for which payments are delinquent are placed on non-accrual status, and thereafter interest income is recognized only when cash payments are received. Realized investment gains and losses on sales are reported as a component of revenues based upon specific identification of the investment assets sold. Impairments are reported as realized investment losses, and include credit losses (and any subsequent recoveries) on fixed maturities and mortgage participations, and intend-to-sell impairment losses on fixed maturities. Changes in the fair value of equity securities are reported in net realized and unrealized investment gains (losses), including increases and decreases in fair value on securities that are still held and realized gains and losses on securities that have been sold. The Company reviews fixed maturity securities in an unrealized loss position and assesses whether it intends to sell the security or more likely than not will be required to sell the security before the recovery of its amortized cost basis. If the debt security meets either of these two criteria, an intend-to-sell impairment is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value at the impairment measurement date. If neither of the above criteria are met, the credit loss portion of the unrealized loss is recorded through earnings and the non-credit portion remains in other comprehensive income. Credit losses are estimated by comparing the amortized cost of the fixed maturity security with the net present value of the security’s projected future cash flows, discounted at the effective interest rate implicit in the investment prior to impairment. The non-credit portion of the impairment is equal to the difference between the fair value and the net present value of the security’s cash flows at the impairment measurement date. Until January 1, 2020, intend-to-sell impairments and credit losses on fixed maturities resulted in a reduction of the amortized cost basis of the security, and reversal of an impairment was not allowed. Beginning January 1, 2020, credit losses are recorded through an allowance for credit losses rather than an adjustment to amortized cost. Recoveries of impairments on fixed maturities are recognized as reversals of the allowance for credit loss and are no longer accreted as investment income through an adjustment to investment yield. The allowance for credit losses is limited to the amount that fair value is less than amortized cost and therefore, increases in the fair value of investments due to reasons other than credit could result in decreases in the allowance and an increase in net income. Mortgage participations are pooled by similar risk characteristics and evaluated for credit losses. The allowance for credit losses is calculated using expected loss rates, which vary based on risk factors such as property type, geographic market, and loan-to-value and debt service coverage ratios.
FINANCIAL INSTRUMENTS	C. Financial Instruments In the normal course of business, the Company may enter into transactions involving various types of financial instruments, including debt, investments such as fixed maturities, equity securities and mortgage loans, investment and loan commitments, swap contracts, option contracts, forward contracts and futures contracts. These instruments involve credit risk and could also be subject to risk of loss due to interest rate fluctuation. The Company evaluates and monitors each financial instrument individually and, when appropriate, obtains collateral or other security to minimize losses.
CASH AND CASH EQUIVALENTS	D. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks and highly liquid debt instruments purchased with an original maturity of three months or less.
DEFERRED ACQUISITION COSTS	E. Deferred Acquisition Costs Acquisition costs consist of commissions, underwriting costs and other costs, which vary with, and are primarily related to, the successful production of premiums. Acquisition costs are deferred and amortized over the terms of the insurance policies. Deferred acquisition costs (“DAC”) for each operating segment are reviewed to determine if the costs are recoverable from future income, including investment income. If such costs are determined to be unrecoverable, they are expensed at the time of determination. Although recoverability of DAC is not assured, the Company believes it is more likely than not that all of these costs will be recovered. The amount of DAC considered recoverable, however, could be reduced in the near term if the estimates of total revenues discussed above are reduced or permanently impaired as a result of a disposition of a line of business. The amount of amortization of DAC could be revised in the near term if any of the estimates discussed above are revised.
REINSURANCE RECOVERABLES	F. Reinsurance Recoverables The Company shares certain insurance risks it has underwritten, through the use of reinsurance contracts, with various insurance entities. Reinsurance accounting is followed for ceded transactions when the risk transfer provisions of ASC 944, Financial Services – Insurance, have been met. As a result, when the Company experiences loss or claims events that are subject to a reinsurance contract, reinsurance recoverables are recorded. The amount of the reinsurance recoverable can vary based on the terms of the reinsurance contract, the size of the individual loss or claim, or the aggregate amount of all losses or claims in a particular line or book of business or an aggregate amount associated with a particular accident year. The valuation of losses or claims recoverable depends on whether the underlying loss or claim is a reported loss or claim, or an incurred but not reported loss. For reported losses and claims, the Company values reinsurance recoverables at the time the underlying loss or claim is recognized, in accordance with contract terms. For incurred but not reported losses, the Company estimates the amount of reinsurance recoverables based on the terms of the reinsurance contracts and historical reinsurance recovery information and applies that information to the gross loss reserve. Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured business and the balance is disclosed separately in the financial statements. However, the ultimate amount of the reinsurance recoverable is not known until all losses and claims are settled. Allowances are established for amounts deemed uncollectible and reinsurance recoverables are recorded net of these allowances. The Company evaluates the financial condition of its reinsurers and monitors concentration risk to minimize its exposure to significant credit losses from individual reinsurers.
PROPERTY, EQUIPMENT, CAPITALIZED SOFTWARE AND LEASES	G. Property, Equipment, Capitalized Software AND LEASES Property, equipment, leasehold improvements and capitalized software are recorded at cost, less accumulated depreciation and amortization. Depreciation is generally provided using the straight-line method over the estimated useful lives of the related assets, which generally range from 3 to 30 years. The estimated useful life for capitalized software is generally 5 to 7 years. Amortization of leasehold improvements is provided using the straight-line method over the lesser of the term of the lease or the estimated useful life of the improvements. The Company has entered into operating and financing leases through which it uses “right-of-use” assets that are recorded at the present value of future minimum lease payments, less accumulated depreciation. Depreciation is generally provided using the straight-line method over the estimated useful lives of the related assets, which generally range from 4 to 6 years for real estate and fleet leases. The Company tests for the recoverability of long-lived assets whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The Company recognizes impairment losses only to the extent that the carrying amounts of long-lived assets exceed the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets. When an impairment loss occurs, the Company reduces the carrying value of the asset to fair value and no longer depreciates the asset. Fair values are estimated using discounted cash flow analysis.
GOODWILL AND INTANGIBLE ASSETS	H. GOODWILL AND INTANGIBLE ASSETS In accordance with the provisions of ASC 350, Intangibles – Goodwill and Other, the Company carries its goodwill at cost, net of amortization accumulated prior to January 1, 2002, and net of impairments. Increases to goodwill are generated through acquisition and represent the excess of the cost of an acquisition over the fair value of net assets acquired, including any intangibles acquired. Since January 1, 2002, goodwill is no longer amortized but rather, is reviewed for impairment. Additionally, acquisitions can also produce intangible assets, which have either a definite or indefinite life. Intangible assets with definite lives are amortized over that life, whereas those intangible assets determined to have an indefinite life are reviewed at least annually for impairment. The Company tests for the recoverability of goodwill and intangible assets with indefinite lives annually, or whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The Company recognizes impairment losses only to the extent that the carrying amounts of reporting units with goodwill exceed the fair value. The amount of the impairment loss that would be recognized is determined based upon the excess of the carrying value of goodwill compared to the implied fair value of the goodwill, as determined with respect to all assets and liabilities of the reporting unit. The Company has performed its annual review of goodwill and intangible assets with indefinite lives for impairment in the fourth quarters of 2020 and 2019 with no impairments recognized. At December 31, 2020 and 2019, the Company held goodwill of $178.8 million and intangible assets with indefinite lives of $15.0 million.
LIABILITIES FOR LOSSES, LAE, AND UNEARNED PREMIUMS	I. LIABILITIES FOR LOSSES, LAE AND UNEARNED PREMIUMS Liabilities for outstanding claims, losses and loss adjustment expenses (“LAE”) are estimates of payments to be made for reported losses and LAE and estimates of losses and LAE incurred but not reported. These liabilities are determined using case basis evaluations and statistical analyses of historical loss patterns and represent estimates of the ultimate cost of all losses incurred but not paid. These estimates are continually reviewed and adjusted as necessary; adjustments are reflected in current operations. Estimated amounts of salvage and subrogation on unpaid losses are deducted from the liability for unpaid claims. Premiums for direct and assumed business are reported as earned on a pro-rata basis over the contract period. The unexpired portion of these premiums is recorded as unearned premiums. All losses, LAE and unearned premium liabilities are based on the various estimates discussed in this note. Although the adequacy of these amounts cannot be assured, the Company believes that it is more likely than not that these liabilities and accruals will be sufficient to meet future obligations of policies in force. The amount of liabilities and accruals, however, could be revised in the near-term if the estimates discussed above are revised.
DEBT	J. Debt The Company’s debt at December 31, 2020 includes senior and subordinated debentures. Debt instruments are carried at principal amount borrowed, net of any applicable unamortized discounts and issuance costs. See Note 6 – “Debt and Credit Arrangements.”
PREMIUM, PREMIUM RECEIVABLE, FEE REVENUE AND RELATED EXPENSES	K. Premium, Premium Receivable, Fee Revenue and Related Expenses Insurance premiums written are generally recorded at the policy inception and are primarily earned on a pro-rata basis over the terms of the policies for all products. Premiums written may also include estimates that are derived from multiple sources, which include the historical experience of the underlying business, similar businesses and available industry information. These estimates are regularly reviewed and updated, and any resulting adjustments are included in the current year’s results. Unearned premium reserves represent the portion of premiums written that relates to the unexpired terms of the underlying in-force insurance policies and reinsurance contracts. Premium receivables reflect the unpaid balance of premiums written as of the balance sheet date. Premium receivables are generally short-term in nature and are reported net of an allowance for estimated uncollectible premium accounts. The Company reviews its receivables for collectability at the balance sheet date. The allowance for uncollectible accounts was not material as of December 31, 2020 and 2019. Ceded premiums are charged to income over the applicable term of the various reinsurance contracts with third-party reinsurers. Reinsurance reinstatement premiums, when required, are recognized in the same period as the loss event that gave rise to the reinstatement premiums. Losses and related expenses are matched with premiums, resulting in their recognition over the lives of the contracts. This matching is accomplished through estimated and unpaid losses and amortization of deferred acquisition costs.
INCOME TAXES	L. Income Taxes The Company is subject to the tax laws and regulations of the U.S. and foreign countries in which it operates or where it operated previously. The Company files a consolidated U.S. federal income tax return that includes the holding company and its U.S. subsidiaries. Generally, taxes are accrued at the U.S. statutory tax rate of 21% for income from the U.S. operations. The Company accrues taxes on certain non-U.S. income that is subject to U.S. tax at the enacted U.S. tax rate. Foreign tax credits, where available, were utilized to offset U.S. tax as permitted. The Company’s accounting for income taxes represents its best estimate of various events and transactions. Deferred income taxes are generally recognized when assets and liabilities have different values for financial statement and tax reporting purposes, and for other temporary taxable and deductible differences as defined by ASC 740, Income Taxes (“ASC 740”). These temporary differences are measured at the balance sheet date using enacted tax rates expected to apply to taxable income in the years the temporary differences are expected to reverse. These differences result primarily from insurance reserves, investments, deferred acquisition costs, software capitalization and employee benefit plans. The realization of deferred tax assets depends upon the existence of sufficient taxable income within the carryback or carryforward periods under the tax law in the applicable tax jurisdiction. Consideration is given to all available positive and negative evidence, including reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. Valuation allowances are established if, based on available information, it is determined that it is more likely than not that all or some portion of the deferred tax assets will not be realized. Changes in valuation allowances are generally reflected in income tax expense or as an adjustment to other comprehensive income (loss) depending on the nature of the item for which the valuation allowance is being recorded.
STOCK-BASED COMPENSATION	M. Stock-Based Compensation The Company recognizes the fair value of compensation costs for all share-based payments, including employee stock options, in the financial statements. Unvested awards are generally expensed on a straight-line basis, by tranche, over the vesting period of the award. The Company’s stock-based compensation plans are discussed further in Note 10 – “Stock-Based Compensation Plans.”
EARNINGS PER SHARE	N. Earnings Per Share Earnings per share (“EPS”) for the years ended December 31, 2020, 2019 and 2018 is based on a weighted average of the number of shares outstanding during each year. Basic and diluted EPS is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the period. The weighted average shares outstanding used to calculate basic EPS differ from the weighted average shares outstanding used in the calculation of diluted EPS due to the effect of dilutive employee stock options, nonvested stock grants and other contingently issuable shares. If the effect of such items is antidilutive, the weighted average shares outstanding used to calculate diluted EPS would be equal to those used to calculate basic EPS. Options to purchase shares of common stock whose exercise prices are greater than the average market price of the common shares are not included in the computation of diluted earnings per share because the effect would be antidilutive.
NEW ACCOUNTING PRONOUNCEMENTS	O. New Accounting Pronouncements Recently Implemented Standards In August 2018, the Financial Accounting Standards Board (“FASB”) issued ASC Update No. 2018-14 (Topic 715-20) Compensation – Retirement Benefits – Defined Benefit Plans – General – Disclosure Framework – Changes to the Disclosure Requirements for the Defined Benefit Plans. This ASC update modifies disclosures related to defined benefit pension or other postretirement plans. This ASC update removes the disclosure of amounts in AOCI expected to be recognized over the next fiscal year and the effects of a one percentage point change of health care cost trends on net periodic benefit costs and postretirement benefit obligations and clarifies the specific requirements of disclosures related to the project benefit obligation and accumulated benefit obligation. This ASC Update also adds disclosures related to weighted average crediting rates for cash balance plans and requires disclosure of an explanation of any significant gains and losses related to changes in benefit obligations for the period. The amendments in this ASC update are effective for fiscal years ending after December 15, 2020, and should be applied on a retrospective basis to all periods presented. Early adoption is permitted. The Company implemented this guidance effective December 31, 2020, and it did not have an impact on the Company’s financial position or results of operations as the update is disclosure related. In August 2018, the FASB issued ASC Update No. 2018-13, (Topic 820) Fair Value Measurement, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This update removes the requirement for disclosure of the following: 1) the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2) the policy for timing of transfers between levels, and 3) the valuation processes for Level 3 fair value measurements. This update also added a requirement to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, in addition to other fair value disclosure modifications. This update required both prospective and retrospective application to certain disclosures upon implementation. The Company implemented this guidance effective January 1, 2020 and it did not have an impact on the Company’s financial position or results of operations as the update is disclosure related. In February 2018, the FASB issued ASC Update No. 2018-02 (Topic 220) Income Statement – Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASC update allows for a reclassification into retained earnings of the stranded tax effects in AOCI resulting from the enactment of the TCJA. Current guidance requires the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that includes the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification would include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts at the date of the enactment of the TCJA related to items in AOCI. The updated guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company early adopted this guidance effective January 1, 2018 with a cumulative effect adjustment, which reclassified $6.5 million of benefits from AOCI to retained earnings with no overall impact on the Company’s financial position. In March 2017, the FASB issued ASC Update No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This guidance shortens the amortization period of premiums on certain purchased callable debt securities to the earliest call date. The updated guidance is effective for annual and interim periods beginning after December 15, 2018, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company implemented this guidance effective January 1, 2019. Implementing this guidance resulted in a cumulative effect adjustment which reclassified unrealized losses, net of tax, of $1.5 million from accumulated other comprehensive income to retained earnings. In June 2016, the FASB issued ASC Update No. 2016-13, (Topic 326) Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASC Update No. 2016-13”). This ASC update introduces new guidance for the accounting for credit losses on financial instruments within its scope. A new model, referred to as the current expected credit losses model, requires an entity to determine credit-related impairment losses for financial instruments held at amortized cost and to estimate these expected credit losses over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider both historical and current information, reasonable and supportable forecasts, as well as estimates of prepayments. The estimated credit losses and subsequent adjustment to such loss estimates are recorded through an allowance account which is deducted from the amortized cost of the financial instrument, with the offset recorded in current earnings. ASC Update No. 2016-13 also modifies the impairment model for available-for-sale debt securities. The new model requires an estimate of expected credit losses only when the fair value is below the amortized cost of an asset, thus the length of time the fair value of an available-for-sale debt security has been below the amortized cost no longer affects the determination of whether a credit loss exists. In addition, credit losses on available-for-sale debt securities will be limited to the difference between the security’s amortized cost basis and its fair value. In November 2018, the FASB issued ASC Update No. 2018-19, Codification Improvement to Topic 326, Financial Instruments – Credit Losses, which explicitly states that receivables arising from operating leases are not within the scope of Subtopic 326-20. In 2019 and 2020, the FASB issued several updates to ASC Update 2016-13, including the issuance in April 2019 of ASC Update 2019-04, Codification Improvements to Topic 360, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging and Topic 825, Financial Instruments, the issuance in May 2019 of ASC Update 2019-05, Financial Instruments – Credit Losses (Topic 326): Targeted Transition Relief, the issuance in November 2019 of ASC Update No.2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses and the issuance in February 2020 of ASC Update 2020-02, Financial Instruments – Credit Losses (Topic 326) and Leases (Topic 842) – Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842). The Company implemented this guidance effective January 1, 2020 and it did not have a material impact on its financial position or results of operations. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASC Update No. 2016-02, Leases (Topic 842) . This ASC update requires a lessee to recognize a right-of-use asset, which represents the lessee’s right to use a specified asset for the lease term, and a corresponding lease liability, which represents a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, for all leases that extend beyond 12 months. For finance or capital leases, interest on the lease liability will be recognized separately from amortization of the right-of-use asset in the statements of income and comprehensive income. In addition, the repayment of the principal portion of the lease liability will be classified as a financing activity while the interest component will be included in the operating section of the statement of cash flows. For operating leases, the asset and liability will be amortized as a single lease cost, such that the cost of the lease is allocated over the lease term, on a generally straight-line basis, with all cash flows included within operating activities in the statement of cash flows. ASC Update No. 2016-02 requires that implementation of this guidance be through a modified retrospective transition approach. In July 2018, the FASB issued ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities with an additional transition method to adopt ASC Update No. 2016-02. Under this optional transition method, an entity can initially apply the new guidance at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company implemented this guidance effective January 1, 2019 using the optional transition method provided in ASC Update No. 2018-11 and elected to utilize the practical expedient package available in ASC Update 2016-02. The Company has also elected to utilize the practical expedient which allows an entity not to separate lease and nonlease components for all of its asset classes. The effect of implementing this guidance increased total assets and total liabilities each by approximately $35 million on January 1, 2019 and did not have a material effect on the results of operations. Recently Issued Standards In October 2020, the FASB issued ASC Update No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs. This guidance clarifies, for each reporting period, that an entity should reevaluate whether a callable debt security with multiple call dates is required to amortize any premium to the next call date. The updated guidance is effective for annual and interim periods beginning after December 15, 2020 and should be applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company does not expect the adoption of ASC Update No. 2020-08 to have a material impact on its financial position or results of operations. In January 2020, the FASB issued ASC Update No. 2020-01 Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). This ASC update clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting when using the measurement alternative under ASC 321. It also clarifies the accounting for certain forward contracts and purchased options accounted for under ASC 815. The updated guidance is effective for annual and interim periods beginning after December 15, 2020. The Company does not expect the adoption of ASC Update No. 2020-01 to have a material impact on its financial position or results of operations. In December 2019, the FASB issued ASC Update No. 2019-12 Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes. This ASC update removes certain exceptions to the general principles in ASC 740, Income Taxes, including intraperiod tax allocation when there is a loss from continuing operations, foreign subsidiary treatment under certain conditions and for calculating interim income taxes when the year-to-date loss exceeds the anticipated loss. This update also clarifies and amends existing guidance related to changes in tax laws, business combinations and employee stock plans, among others. The updated guidance is effective for interim and annual periods beginning after December 15, 2020. Early adoption is permitted, including interim periods. The Company does not expect the adoption of ASC Update No. 2019-12 to have a material effect on its financial position or results of operations.

BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

A. Basis of Presentation and Principles of Consolidation

The consolidated financial statements of The Hanover Insurance Group, Inc. (“THG” or the “Company”), include the accounts of The Hanover Insurance Company (“Hanover Insurance”) and Citizens Insurance Company of America (“Citizens”), THG’s principal property and casualty companies; and other insurance and non-insurance subsidiaries. These legal entities conduct their operations through several business segments discussed in Note 13 – “Segment Information.” The consolidated financial statements also include the Company’s discontinued operations, consisting primarily of the Company’s former accident and health and life insurance businesses and its former Chaucer international business, Chaucer Holdings Limited (“Chaucer”), a United Kingdom (“U.K.”) domiciled specialist insurance underwriting group which operates through the Society and Corporation of Lloyd’s (“Lloyd’s”), and other international insurance and non-insurance subsidiaries. All intercompany accounts and transactions have been eliminated. On December 28, 2018, the Company completed the sale of Chaucer to China Reinsurance (Group) Corporation (“China Re”), and subsequently completed the sales of the Chaucer-related Irish and Australian entities on February 14, 2019 and April 10, 2019, respectively. Accordingly, for all prior periods presented in this Annual Report on Form 10-K, operations from Chaucer are presented as discontinued operations.

The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) requires the Company 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 the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of the Company’s management these financial statements reflect all adjustments, consisting of normal recurring items, necessary for a fair presentation of the financial position and results of operations.

INVESTMENTS

B. Investments

Fixed maturities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses, net of taxes, reported in accumulated other comprehensive income (“AOCI”), a separate component of shareholders’ equity. The amortized cost of fixed maturities is adjusted for amortization of premiums and accretion of discounts to maturity.

Equity securities are carried at fair value. Increases and decreases in fair value are reported in net income.

Other investments consist primarily of mortgage participations and limited partnerships. Mortgage participations represent interests in commercial mortgage loans originated and serviced by a third-party of which the Company shares, on a pro-rata basis, in all related cash flows of the underlying mortgage loans. Mortgage participations are stated at unpaid principal balances adjusted for deferred fees or expenses, net of an allowance for credit losses. Prior to May 2018, certain reacquisition rights retained by the third-party in the loan participations required that these investments be accounted for as secured borrowings under Accounting Standards Codification (“ASC”) 860, Transfers and Servicing. Investments in limited partnerships include interests in private equity and real estate funds. Investments in limited partnership interests purchased prior to January 1, 2018, where the Company’s interest is so minor that it exercises virtually no influence over operating and financial policies, are accounted for at fair value utilizing the net asset value (“NAV”) as a practical expedient to determine fair value. All other limited partnerships are accounted for in accordance with the equity method of accounting.

The Company excludes accrued interest receivable from both the estimated fair value and the amortized cost basis of its investment securities and reports such amounts separately on the consolidated balance sheets as accrued investment income. When accrued interest receivable is deemed uncollectible it is written off as a charge to investment income, rather than recorded through an allowance.

Net investment income includes interest, dividends and income from limited partnership interests. Interest income is recognized based on the effective yield method, which includes the amortization of premiums and accretion of discounts. The effective yield used to determine the amortization for fixed maturities subject to prepayment risk, such as mortgage-backed and asset-backed securities, is recalculated and adjusted periodically based upon actual historical and projected future cash flows. The adjustment to yields for highly rated prepayable fixed maturities is accounted for using the retrospective method. The adjustment to yields for all other prepayable fixed maturities is accounted for using the prospective method. Fixed maturities and mortgage participations for which payments are delinquent are placed on non-accrual status, and thereafter interest income is recognized only when cash payments are received.

Realized investment gains and losses on sales are reported as a component of revenues based upon specific identification of the investment assets sold. Impairments are reported as realized investment losses, and include credit losses (and any subsequent recoveries) on fixed maturities and mortgage participations, and intend-to-sell impairment losses on fixed maturities. Changes in the fair value of equity securities are reported in net realized and unrealized investment gains (losses), including increases and decreases in fair value on securities that are still held and realized gains and losses on securities that have been sold.

The Company reviews fixed maturity securities in an unrealized loss position and assesses whether it intends to sell the security or more likely than not will be required to sell the security before the recovery of its amortized cost basis. If the debt security meets either of these two criteria, an intend-to-sell impairment is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value at the impairment measurement date. If neither of the above criteria are met, the credit loss portion of the unrealized loss is recorded through earnings and the non-credit portion remains in other comprehensive income. Credit losses are estimated by comparing the amortized cost of the fixed maturity security with the net present value of the security’s projected future cash flows, discounted at the effective interest rate implicit in the investment prior to impairment. The non-credit portion of the impairment is equal to the difference between the fair value and the net present value of the security’s cash flows at the impairment measurement date. Until January 1, 2020, intend-to-sell impairments and credit losses on fixed maturities resulted in a reduction of the amortized cost basis of the security, and reversal of an impairment was not allowed. Beginning January 1, 2020, credit losses are recorded through an allowance for credit losses rather than an adjustment to amortized cost. Recoveries of impairments on fixed maturities are recognized as reversals of the allowance for credit loss and are no longer accreted as investment income through an adjustment to investment yield. The allowance for credit losses is limited to the amount that fair value is less than amortized cost and therefore, increases in the fair value of investments due to reasons other than credit could result in decreases in the allowance and an increase in net income.

Mortgage participations are pooled by similar risk characteristics and evaluated for credit losses. The allowance for credit losses is calculated using expected loss rates, which vary based on risk factors such as property type, geographic market, and loan-to-value and debt service coverage ratios.

FINANCIAL INSTRUMENTS

C. Financial Instruments

In the normal course of business, the Company may enter into transactions involving various types of financial instruments, including debt, investments such as fixed maturities, equity securities and mortgage loans, investment and loan commitments, swap contracts, option contracts, forward contracts and futures contracts. These instruments involve credit risk and could also be subject to risk of loss due to interest rate fluctuation. The Company evaluates and monitors each financial instrument individually and, when appropriate, obtains collateral or other security to minimize losses.

CASH AND CASH EQUIVALENTS

D. Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, amounts due from banks and highly liquid debt instruments purchased with an original maturity of three months or less.

DEFERRED ACQUISITION COSTS

E. Deferred Acquisition Costs

Acquisition costs consist of commissions, underwriting costs and other costs, which vary with, and are primarily related to, the successful production of premiums. Acquisition costs are deferred and amortized over the terms of the insurance policies.

Deferred acquisition costs (“DAC”) for each operating segment are reviewed to determine if the costs are recoverable from future income, including investment income. If such costs are determined to be unrecoverable, they are expensed at the time of determination. Although recoverability of DAC is not assured, the Company believes it is more likely than not that all of these costs will be recovered. The amount of DAC considered recoverable, however, could be reduced in the near term if the estimates of total revenues discussed above are reduced or permanently impaired as a result of a disposition of a line of business. The amount of amortization of DAC could be revised in the near term if any of the estimates discussed above are revised.

REINSURANCE RECOVERABLES

F. Reinsurance Recoverables

The Company shares certain insurance risks it has underwritten, through the use of reinsurance contracts, with various insurance entities. Reinsurance accounting is followed for ceded transactions when the risk transfer provisions of ASC 944, Financial Services – Insurance, have been met. As a result, when the Company experiences loss or claims events that are subject to a reinsurance contract, reinsurance recoverables are recorded. The amount of the reinsurance recoverable can vary based on the terms of the reinsurance contract, the size of the individual loss or claim, or the aggregate amount of all losses or claims in a particular line or book of business or an aggregate amount associated with a particular accident year. The valuation of losses or claims recoverable depends on whether the underlying loss or claim is a reported loss or claim, or an incurred but not reported loss. For reported losses and claims, the Company values reinsurance recoverables at the time the underlying loss or claim is recognized, in accordance with contract terms. For incurred but not reported losses, the Company estimates the amount of reinsurance recoverables based on the terms of the reinsurance contracts and historical reinsurance recovery information and applies that information to the gross loss reserve. Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured business and the balance is disclosed separately in the financial statements. However, the ultimate amount of the reinsurance recoverable is not known until all losses and claims are settled. Allowances are established for amounts deemed uncollectible and reinsurance recoverables are recorded net of these allowances. The Company evaluates the financial condition of its reinsurers and monitors concentration risk to minimize its exposure to significant credit losses from individual reinsurers.

PROPERTY, EQUIPMENT, CAPITALIZED SOFTWARE AND LEASES

G. Property, Equipment, Capitalized Software AND LEASES

Property, equipment, leasehold improvements and capitalized software are recorded at cost, less accumulated depreciation and amortization. Depreciation is generally provided using the straight-line method over the estimated useful lives of the related assets, which generally range from 3 to 30 years. The estimated useful life for capitalized software is generally 5 to 7 years. Amortization of leasehold improvements is provided using the straight-line method over the lesser of the term of the lease or the estimated useful life of the improvements.

The Company has entered into operating and financing leases through which it uses “right-of-use” assets that are recorded at the present value of future minimum lease payments, less accumulated depreciation. Depreciation is generally provided using the straight-line method over the estimated useful lives of the related assets, which generally range from 4 to 6 years for real estate and fleet leases.

The Company tests for the recoverability of long-lived assets whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The Company recognizes impairment losses only to the extent that the carrying amounts of long-lived assets exceed the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets. When an impairment loss occurs, the Company reduces the carrying value of the asset to fair value and no longer depreciates the asset. Fair values are estimated using discounted cash flow analysis.

GOODWILL AND INTANGIBLE ASSETS

H. GOODWILL AND INTANGIBLE ASSETS

In accordance with the provisions of ASC 350, Intangibles – Goodwill and Other, the Company carries its goodwill at cost, net of amortization accumulated prior to January 1, 2002, and net of impairments. Increases to goodwill are generated through acquisition and represent the excess of the cost of an acquisition over the fair value of net assets acquired, including any intangibles acquired. Since January 1, 2002, goodwill is no longer amortized but rather, is reviewed for impairment. Additionally, acquisitions can also produce intangible assets, which have either a definite or indefinite life. Intangible assets with definite lives are amortized over that life, whereas those intangible assets determined to have an indefinite life are reviewed at least annually for impairment.

The Company tests for the recoverability of goodwill and intangible assets with indefinite lives annually, or whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The Company recognizes impairment losses only to the extent that the carrying amounts of reporting units with goodwill exceed the fair value. The amount of the impairment loss that would be recognized is determined based upon the excess of the carrying value of goodwill compared to the implied fair value of the goodwill, as determined with respect to all assets and liabilities of the reporting unit. The Company has performed its annual review of goodwill and intangible assets with indefinite lives for impairment in the fourth quarters of 2020 and 2019 with no impairments recognized. At December 31, 2020 and 2019, the Company held goodwill of $178.8 million and intangible assets with indefinite lives of $15.0 million.

LIABILITIES FOR LOSSES, LAE, AND UNEARNED PREMIUMS

I. LIABILITIES FOR LOSSES, LAE AND UNEARNED PREMIUMS

Liabilities for outstanding claims, losses and loss adjustment expenses (“LAE”) are estimates of payments to be made for reported losses and LAE and estimates of losses and LAE incurred but not reported. These liabilities are determined using case basis evaluations and statistical analyses of historical loss patterns and represent estimates of the ultimate cost of all losses incurred but not paid. These estimates are continually reviewed and adjusted as necessary; adjustments are reflected in current operations. Estimated amounts of salvage and subrogation on unpaid losses are deducted from the liability for unpaid claims.

Premiums for direct and assumed business are reported as earned on a pro-rata basis over the contract period. The unexpired portion of these premiums is recorded as unearned premiums.

All losses, LAE and unearned premium liabilities are based on the various estimates discussed in this note. Although the adequacy of these amounts cannot be assured, the Company believes that it is more likely than not that these liabilities and accruals will be sufficient to meet future obligations of policies in force. The amount of liabilities and accruals, however, could be revised in the near-term if the estimates discussed above are revised.

DEBT

J. Debt

The Company’s debt at December 31, 2020 includes senior and subordinated debentures. Debt instruments are carried at principal amount borrowed, net of any applicable unamortized discounts and issuance costs. See Note 6 – “Debt and Credit Arrangements.”

PREMIUM, PREMIUM RECEIVABLE, FEE REVENUE AND RELATED EXPENSES

K. Premium, Premium Receivable, Fee Revenue and Related Expenses

Insurance premiums written are generally recorded at the policy inception and are primarily earned on a pro-rata basis over the terms of the policies for all products. Premiums written may also include estimates that are derived from multiple sources, which include the historical experience of the underlying business, similar businesses and available industry information. These estimates are regularly reviewed and updated, and any resulting adjustments are included in the current year’s results. Unearned premium reserves represent the portion of premiums written that relates to the unexpired terms of the underlying in-force insurance policies and reinsurance contracts. Premium receivables reflect the unpaid balance of premiums written as of the balance sheet date. Premium receivables are

generally short-term in nature and are reported net of an allowance for estimated uncollectible premium accounts. The Company reviews its receivables for collectability at the balance sheet date. The allowance for uncollectible accounts was not material as of December 31, 2020 and 2019. Ceded premiums are charged to income over the applicable term of the various reinsurance contracts with third-party reinsurers. Reinsurance reinstatement premiums, when required, are recognized in the same period as the loss event that gave rise to the reinstatement premiums. Losses and related expenses are matched with premiums, resulting in their recognition over the lives of the contracts. This matching is accomplished through estimated and unpaid losses and amortization of deferred acquisition costs.

INCOME TAXES

L. Income Taxes

The Company is subject to the tax laws and regulations of the U.S. and foreign countries in which it operates or where it operated previously. The Company files a consolidated U.S. federal income tax return that includes the holding company and its U.S. subsidiaries. Generally, taxes are accrued at the U.S. statutory tax rate of 21% for income from the U.S. operations. The Company accrues taxes on certain non-U.S. income that is subject to U.S. tax at the enacted U.S. tax rate. Foreign tax credits, where available, were utilized to offset U.S. tax as permitted.

The Company’s accounting for income taxes represents its best estimate of various events and transactions.

Deferred income taxes are generally recognized when assets and liabilities have different values for financial statement and tax reporting purposes, and for other temporary taxable and deductible differences as defined by ASC 740, Income Taxes (“ASC 740”). These temporary differences are measured at the balance sheet date using enacted tax rates expected to apply to taxable income in the years the temporary differences are expected to reverse. These differences result primarily from insurance reserves, investments, deferred acquisition costs, software capitalization and employee benefit plans.

The realization of deferred tax assets depends upon the existence of sufficient taxable income within the carryback or carryforward periods under the tax law in the applicable tax jurisdiction. Consideration is given to all available positive and negative evidence, including reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. Valuation allowances are established if, based on available information, it is determined that it is more likely than not that all or some portion of the deferred tax assets will not be realized. Changes in valuation allowances are generally reflected in income tax expense or as an adjustment to other comprehensive income (loss) depending on the nature of the item for which the valuation allowance is being recorded.

STOCK-BASED COMPENSATION

M. Stock-Based Compensation

The Company recognizes the fair value of compensation costs for all share-based payments, including employee stock options, in the financial statements. Unvested awards are generally expensed on a straight-line basis, by tranche, over the vesting period of the award. The Company’s stock-based compensation plans are discussed further in Note 10 – “Stock-Based Compensation Plans.”

EARNINGS PER SHARE

N. Earnings Per Share

Earnings per share (“EPS”) for the years ended December 31, 2020, 2019 and 2018 is based on a weighted average of the number of shares outstanding during each year. Basic and diluted EPS is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the period. The weighted average shares outstanding used to calculate basic EPS differ from the weighted average shares outstanding used in the calculation of diluted EPS due to the effect of dilutive employee stock options, nonvested stock grants and other contingently issuable shares. If the effect of such items is antidilutive, the weighted average shares outstanding used to calculate diluted EPS would be equal to those used to calculate basic EPS.

Options to purchase shares of common stock whose exercise prices are greater than the average market price of the common shares are not included in the computation of diluted earnings per share because the effect would be antidilutive.

NEW ACCOUNTING PRONOUNCEMENTS

O. New Accounting Pronouncements

Recently Implemented Standards

In August 2018, the Financial Accounting Standards Board (“FASB”) issued ASC Update No. 2018-14 (Topic 715-20) Compensation – Retirement Benefits – Defined Benefit Plans – General – Disclosure Framework – Changes to the Disclosure Requirements for the Defined Benefit Plans. This ASC update modifies disclosures related to defined benefit pension or other postretirement plans. This ASC update removes the disclosure of amounts in AOCI expected to be recognized over the next fiscal year and the effects of a one percentage point change of health care cost trends on net periodic benefit costs and postretirement benefit obligations and clarifies the specific requirements of disclosures related to the project benefit obligation and accumulated benefit obligation. This ASC Update also adds disclosures related to weighted average crediting rates for cash balance plans and requires disclosure of an explanation of any significant gains and losses related to changes in benefit obligations for the period. The amendments in this ASC update are effective for fiscal years ending after December 15, 2020, and should be applied on a retrospective basis to all periods presented. Early adoption is permitted. The Company implemented this guidance effective December 31, 2020, and it did not have an impact on the Company’s financial position or results of operations as the update is disclosure related.

In August 2018, the FASB issued ASC Update No. 2018-13, (Topic 820) Fair Value Measurement, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This update removes the requirement for disclosure of the following: 1) the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2) the policy for timing of transfers between levels, and 3) the valuation processes for Level 3 fair value measurements. This update also added a requirement to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, in addition to other fair value disclosure modifications. This update required both prospective and retrospective application to certain disclosures upon implementation. The Company implemented this guidance effective January 1, 2020 and it did not have an impact on the Company’s financial position or results of operations as the update is disclosure related.

In February 2018, the FASB issued ASC Update No. 2018-02 (Topic 220) Income Statement – Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASC update allows for a reclassification into retained earnings of the stranded tax effects in AOCI resulting from the enactment of the TCJA. Current guidance requires the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that includes the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification would include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts at the date of the enactment of the TCJA related to items in AOCI. The updated guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company early adopted this guidance effective January 1, 2018 with a cumulative effect adjustment, which reclassified $6.5 million of benefits from AOCI to retained earnings with no overall impact on the Company’s financial position.

In March 2017, the FASB issued ASC Update No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This guidance shortens the amortization period of premiums on certain purchased callable debt securities to the earliest call date. The updated guidance is effective for annual and interim periods beginning after December 15, 2018, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company implemented this guidance effective January 1, 2019. Implementing this guidance resulted in a cumulative effect adjustment which reclassified unrealized losses, net of tax, of $1.5 million from accumulated other comprehensive income to retained earnings.

In June 2016, the FASB issued ASC Update No. 2016-13, (Topic 326) Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASC Update No. 2016-13”). This ASC update introduces new guidance for the accounting for credit losses on financial instruments within its scope. A new model, referred to as the current expected credit losses model, requires an entity to determine credit-related impairment losses for financial instruments held at amortized cost and to estimate these expected credit losses over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider both historical and current information, reasonable and supportable forecasts, as well as estimates of prepayments. The estimated credit losses and subsequent adjustment to such loss estimates are recorded through an allowance account which is deducted from the amortized cost of the financial instrument, with the offset recorded in current earnings. ASC Update No. 2016-13 also modifies the impairment model for available-for-sale debt securities. The new model requires an estimate of expected credit losses only when the fair value is below the amortized cost of an asset, thus the length of time the fair value of an available-for-sale debt security has been below the amortized cost no longer affects the determination of whether a credit loss exists. In addition, credit losses on available-for-sale debt securities will be limited to the difference between the security’s amortized cost basis and its fair value. In November 2018, the FASB issued ASC Update No. 2018-19, Codification Improvement to Topic 326, Financial Instruments – Credit Losses, which explicitly states that receivables arising from operating leases are not within the scope of Subtopic 326-20.

In 2019 and 2020, the FASB issued several updates to ASC Update 2016-13, including the issuance in April 2019 of ASC Update 2019-04, Codification Improvements to Topic 360, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging and Topic 825, Financial Instruments, the issuance in May 2019 of ASC Update 2019-05, Financial Instruments – Credit Losses (Topic 326): Targeted Transition Relief, the issuance in November 2019 of ASC Update No.2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses and the issuance in February 2020 of ASC Update 2020-02, Financial Instruments – Credit Losses (Topic 326) and Leases (Topic 842) – Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842). The Company implemented this guidance effective January 1, 2020 and it did not have a material impact on its financial position or results of operations.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASC Update No. 2016-02, Leases (Topic 842) . This ASC update requires a lessee to recognize a right-of-use asset, which represents the lessee’s right to use a specified asset for the lease term, and a corresponding lease liability, which represents a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, for all leases that extend beyond 12 months. For finance or capital leases, interest on the lease liability will be recognized separately from amortization of the right-of-use asset in the statements of income and comprehensive income. In addition, the repayment of the principal portion of the lease liability will be classified as a financing activity while the interest component will be included in the operating section of the statement of cash flows. For operating leases, the asset and liability will be amortized as a single lease cost, such that the cost of the lease is allocated over the lease term, on a generally straight-line basis, with all cash flows

included within operating activities in the statement of cash flows. ASC Update No. 2016-02 requires that implementation of this guidance be through a modified retrospective transition approach. In July 2018, the FASB issued ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities with an additional transition method to adopt ASC Update No. 2016-02. Under this optional transition method, an entity can initially apply the new guidance at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company implemented this guidance effective January 1, 2019 using the optional transition method provided in ASC Update No. 2018-11 and elected to utilize the practical expedient package available in ASC Update 2016-02. The Company has also elected to utilize the practical expedient which allows an entity not to separate lease and nonlease components for all of its asset classes. The effect of implementing this guidance increased total assets and total liabilities each by approximately $35 million on January 1, 2019 and did not have a material effect on the results of operations.

Recently Issued Standards

In October 2020, the FASB issued ASC Update No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs. This guidance clarifies, for each reporting period, that an entity should reevaluate whether a callable debt security with multiple call dates is required to amortize any premium to the next call date. The updated guidance is effective for annual and interim periods beginning after December 15, 2020 and should be applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company does not expect the adoption of ASC Update No. 2020-08 to have a material impact on its financial position or results of operations.

In January 2020, the FASB issued ASC Update No. 2020-01 Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). This ASC update clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting when using the measurement alternative under ASC 321. It also clarifies the accounting for certain forward contracts and purchased options accounted for under ASC 815. The updated guidance is effective for annual and interim periods beginning after December 15, 2020. The Company does not expect the adoption of ASC Update No. 2020-01 to have a material impact on its financial position or results of operations.

In December 2019, the FASB issued ASC Update No. 2019-12 Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes. This ASC update removes certain exceptions to the general principles in ASC 740, Income Taxes, including intraperiod tax allocation when there is a loss from continuing operations, foreign subsidiary treatment under certain conditions and for calculating interim income taxes when the year-to-date loss exceeds the anticipated loss. This update also clarifies and amends existing guidance related to changes in tax laws, business combinations and employee stock plans, among others. The updated guidance is effective for interim and annual periods beginning after December 15, 2020. Early adoption is permitted, including interim periods. The Company does not expect the adoption of ASC Update No. 2019-12 to have a material effect on its financial position or results of operations.

RECLASSIFICATIONS

Q. Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation.
