Accounting Policies [Abstract] | |
Basis of Presentation and Principles of Consolidation | 1. Basis of Presentation and Principles of Consolidation The accompanying unaudited consolidated financial statements of The Hanover Insurance Group, Inc. and subsidiaries (“THG” or the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and with the requirements of Form 10-Q. Certain financial information that is provided in annual financial statements, but is not required in interim reports, has been omitted. The interim consolidated financial statements of THG include the accounts of The Hanover Insurance Company (“Hanover Insurance”) and Citizens Insurance Company of America, THG’s principal U.S. – domiciled property and casualty companies, and certain other insurance and non-insurance subsidiaries. These legal entities conduct their operations through several business segments discussed in Note 9 – “Segment Information”. On September 13, 2018, the Company entered into a definitive agreement to sell Chaucer Holdings Limited (“Chaucer”), a specialist insurance underwriting group which operates through the Society and Corporation of Lloyd’s and the international insurance and non-insurance subsidiaries, which collectively constitute our Chaucer segment, to China Reinsurance (Group) Corporation (“China Re”). Accordingly, as of September 30, 2018 and for all prior periods, Chaucer’s results have been presented as discontinued operations and its assets and liabilities have been classified as held-for-sale in the consolidated financial statements (see Note 3 – “Discontinued Operations”). The interim consolidated financial statements also include discontinued operations of the Company’s accident and health and former life insurance businesses. All intercompany accounts and transactions have been eliminated. The preparation of financial statements in conformity with 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, the accompanying interim consolidated financial statements reflect all adjustments, consisting of normal recurring items, necessary for a fair presentation of the financial position and results of operations. The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 27, 2018. |

Discontinued Chaucer Business | 3. Discontinued Chaucer Business On September 13, 2018, the Company entered into a definitive agreement to sell Chaucer to China Re, for cash consideration of up to $865 million, consisting of initial consideration of $820 million, payable at closing, and contingent consideration of $45 million to be held in escrow. This contingent consideration may be adjusted downward if catastrophe losses incurred in 2018 are above a certain threshold. The Company anticipates that this transaction will result in a net gain. Several factors will affect the ultimate amount of the net gain recognized at the completion of the transaction, including the future earnings of the Chaucer business, the level of catastrophe losses incurred during 2018, the value of investment securities at closing and various tax attributes. The transaction is anticipated to close late this year or in the first quarter of next year, subject to regulatory approvals and other customary closing conditions. THG has agreed to indemnify China Re for certain litigation, regulatory matters and other liabilities related to pre-closing activities of the business being sold.

Income Tax Disclosure [Abstract] | |
Income Taxes | 4. Income Taxes Income tax expense for the nine months ended September 30, 2018 and 2017 has been computed using estimated annual effective tax rates. These rates reflect the change in the U.S. statutory tax rate from 35% to 21%, effective January 1, 2018 and recomputed income to exclude discontinued Chaucer business. These rates are revised, if necessary, at the end of each successive interim period to reflect current estimates of the annual effective tax rates. The tax provision was comprised of U.S. federal income tax expense of $44.5 million and $53.4 million for the nine months ended September 30, 2018 and 2017, respectively. The tax provision recorded in discontinued operations related to discontinued Chaucer business for the nine months ended September 30, 2018 was comprised of a $0.2 million U.S. federal income tax benefit and a $6.8 million foreign income tax expense.

The Company deposits funds with various state and governmental authorities. For a discussion of the Company’s deposits with state and governmental authorities, see also Note 3 – “Investments” of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2017. The amortized cost and fair value by maturity periods for fixed maturities are shown below. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties, or the Company may have the right to put or sell the obligations back to the issuers.

The Company employs a systematic methodology to evaluate declines in fair value below amortized cost for fixed maturity securities. In determining OTTI, the Company evaluates several factors and circumstances, including the issuer’s overall financial condition; the issuer’s credit and financial strength ratings; the issuer’s financial performance, including earnings trends and asset quality; any specific events which may influence the operations of the issuer; the general outlook for market conditions in the industry or geographic region in which the issuer operates; and the length of time and the degree to which the fair value of an issuer’s securities remains below the Company’s amortized cost. The Company also considers any factors that might raise doubt about the issuer’s ability to make contractual payments as they come due and whether the Company expects to recover the entire amortized cost basis of the security. C. Proceeds from sales The proceeds from sales of available-for-sale securities and gross realized gains and gross realized losses on those sales were as follows: Three Months Ended September 30, 2018 2017 Proceeds from Gross Gross Proceeds from Gross Gross (in millions) Sales Gains Losses Sales Gains Losses Fixed maturities, excluding held-for-sale (Chaucer) $ 83.8 $ 0.8 $ 1.5 $ 47.0 $ 2.4 $ 0.3 Fixed maturities, held-for-sale 21.4 0.2 0.1 45.6 0.6 0.2 Total fixed maturities $ 105.2 $ 1.0 $ 1.6 $ 92.6 $ 3.0 $ 0.5 Nine Months Ended September 30, 2018 2017 Proceeds from Gross Gross Proceeds from Gross Gross (in millions) Sales Gains Losses Sales Gains Losses Fixed maturities, excluding held-for-sale (Chaucer) $ 225.1 $ 2.0 $ 5.3 $ 176.9 $ 6.4 $ 1.7 Fixed maturities, held-for-sale 172.5 1.3 1.1 145.8 1.8 0.2 Total fixed maturities $ 397.6 $ 3.3 $ 6.4 $ 322.7 $ 8.2 $ 1.9 D. Other-than-temporary impairments For the three months ended September 30, 2018, total OTTI from continuing operations was $0.7 million, which consisted entirely of fixed maturities. Of this amount, $0.4 million was recognized in earnings and the remaining $0.3 million was recorded as unrealized losses in AOCI. For the nine months ended September 30, 2018, total OTTI from continuing operations was $3.4 million, consisting primarily of fixed maturities and other invested assets. Of this amount, $2.8 million was recognized in earnings and the remaining $0.6 million was recorded as unrealized losses in AOCI. For the three months ended September 30, 2017, total OTTI from continuing operations was $1.5 million, consisting primarily of fixed maturities. Of this amount, $1.3 million was recognized in earnings and the remaining $0.2 million was recorded as unrealized losses in AOCI. For the nine months ended September 30, 2017, total OTTI from continuing operations was $4.9 million, consisting of equity securities, fixed maturities and other invested assets. Of this amount, $4.5 million was recognized in earnings and the remaining $0.4 million was recorded as unrealized losses in AOCI. The methodology and significant inputs used to measure the amount of credit losses on fixed maturities in 2018 and 2017 were as follows: Corporate bonds – the Company utilized a financial model that derives expected cash flows based on probability-of-default factors by credit rating and asset duration and loss-given-default factors based on security type. These factors are based on historical data provided by an independent third-party rating agency. In addition, other market data relevant to the realizability of contractual cash flows may be considered. The following table provides rollforwards of the cumulative amounts related to the credit loss portion of the OTTI losses on fixed maturity securities from continuing operations for which the non-credit portion of the loss is included in other comprehensive income. Three Months Ended September 30, Nine Months Ended September 30, (in millions) 2018 2017 2018 2017 Credit losses at beginning of period, excluding held-for-sale (Chaucer) $ 3.7 $ 9.2 $ 3.6 $ 9.6 Credit losses for which an OTTI was not previously recognized 0.2 0.2 1.0 0.4 Additional credit losses on securities for which an OTTI was previously recognized — — 0.1 0.1 Reductions for securities sold, matured or called — (1.9 ) (0.8 ) (2.6 ) Reductions for securities reclassified as intended to sell — (0.4 ) — (0.4 ) Credit losses at end of period, excluding held-for-sale (Chaucer) $ 3.9 $ 7.1 $ 3.9 $ 7.1 For the three and nine months ended September 30, 2018, total OTTI from discontinued operations of Chaucer was $0.2 million and $0.4 million, respectively. For both the three and nine months ended September 30, 2017, total OTTI from discontinued operations of Chaucer was $0.1 million. E. Equity securities Equity securities are carried at fair value. Effective January 1, 2018, all increases or decreases in fair value on equity securities are reported in net realized and unrealized investment gains (losses) on the Consolidated Statements of Income. Previously, equity securities were categorized as available-for-sale and unrealized gains and losses were reported in AOCI, a separate component of shareholders’ equity. As of December 31, 2017, we held equity securities with a fair value of $576.2 million and a cost of $433.7 million. On January 1, 2018, the Company recorded a cumulative effect adjustment which included the reclassification of net unrealized gains on equities of $142.5 million, pre-tax, from AOCI to retained earnings. The following table provides pre-tax realized and unrealized gains (losses) on equity securities recognized in net income from continuing operations during the three and nine months ended September 30, 2018: (in millions) Three Months Ended Nine Months Ended Net gains recognized during the period $ 23.6 $ 6.7 Less: net losses recognized on equity securities sold during the period (0.2 ) (1.0 ) Net unrealized gains recognized during the period on equity securities still held $ 23.8 $ 7.7 During the three and nine months ended September 30, 2017, there were changes in net unrealized gains on equity securities of $7.9 million and $37.2 million, respectively, recognized in AOCI and net realized gains from sales of equity securities of $11.8 million and $17.6 million, respectively, recognized in earnings. Proceeds from the sale of equities for the three and nine months ended September 30, 2017 were $68.2 million and $114.5 million, respectively. |

Fair Value Disclosures [Abstract] | |
Fair Value | 6. Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability, i.e., exit price, in an orderly transaction between market participants. The Company emphasizes the use of observable market data whenever available in determining fair value. Fair values presented for certain financial instruments are estimates which, in many cases, may differ significantly from the amounts that could be realized upon immediate liquidation. A hierarchy of the three broad levels of fair value are as follows, with the highest priority given to Level 1 as these are the most observable, and the lowest priority given to Level 3: Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 – Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data, including model-derived valuations. Level 3 – Unobservable inputs that are supported by little or no market activity. When more than one level of input is used to determine fair value, the financial instrument is classified as Level 2 or 3 according to the lowest level input that has a significant impact on the fair value measurement. The following methods and assumptions were used to estimate the fair value of each class of financial instruments and have not changed since last year. Fixed Maturities Level 1 securities generally include U.S. Treasury issues and other securities that are highly liquid and for which quoted market prices are available. Level 2 securities are valued using pricing for similar securities and pricing models that incorporate observable inputs including, but not limited to yield curves and issuer spreads. Level 3 securities include issues for which little observable data can be obtained, primarily due to the illiquid nature of the securities, and for which significant inputs used to determine fair value are based on the Company’s own assumptions. The Company utilizes a third party pricing service for the valuation of the majority of its fixed maturity securities and receives one quote per security. When quoted market prices in an active market are available, they are provided by the pricing service as the fair value and such values are classified as Level 1. Since fixed maturities other than U.S. Treasury securities generally do not trade on a daily basis, the pricing service prepares estimates of fair value for those securities using pricing techniques based on a market approach. Inputs into the fair value pricing common to all asset classes include: benchmark U.S. Treasury security yield curves; reported trades of identical or similar fixed maturity securities; broker/dealer quotes of identical or similar fixed maturity securities and structural characteristics such as maturity date, coupon, mandatory principal payment dates, frequency of interest and principal payments, and optional redemption features. Inputs into the fair value applications that are unique by asset class include, but are not limited to: • U.S. government agencies – determination of direct versus indirect government support and whether any contingencies exist with respect to the timely payment of principal and interest. • Foreign government – estimates of appropriate market spread versus underlying related sovereign treasury curve(s) dependent on liquidity and direct or contingent support. • Municipals – overall credit quality, including assessments of the level and variability of: sources of payment such as income, sales or property taxes, levies or user fees; credit support such as insurance; state or local economic and political base; natural resource availability; and susceptibility to natural or man-made catastrophic events such as hurricanes, earthquakes or acts of terrorism. • Corporate fixed maturities – overall credit quality, including assessments of the level and variability of: economic sensitivity; liquidity; corporate financial policies; management quality; regulatory environment; competitive position; ownership; restrictive covenants; and security or collateral. • Residential mortgage-backed securities – estimates of prepayment speeds based upon: historical prepayment rate trends; underlying collateral interest rates; geographic concentration; vintage year; borrower credit quality characteristics; interest rate and yield curve forecasts; government or monetary authority support programs; tax policies; delinquency/default trends; and, in the case of non-agency collateralized mortgage obligations, severity of loss upon default and length of time to recover proceeds following default. • Commercial mortgage-backed securities – overall credit quality, including assessments of the value and supply/demand characteristics of: collateral type such as office, retail, residential, lodging, or other; geographic concentration by region, state, metropolitan statistical area and locale; vintage year; historical collateral performance including defeasance, delinquency, default and special servicer trends; and capital structure support features. • Asset-backed securities – overall credit quality, including assessments of the underlying collateral type such as credit card receivables, auto loan receivables and equipment lease receivables; geographic diversification; vintage year; historical collateral performance including delinquency, default and casualty trends; economic conditions influencing use rates and resale values; and contract structural support features. Generally, all prices provided by the pricing service, except actively traded securities with quoted market prices, are reported as Level 2. The Company holds privately placed fixed maturity securities and certain other fixed maturity securities that do not have an active market and for which the pricing service cannot provide fair values. The Company determines fair values for these securities using either matrix pricing utilizing the market approach or broker quotes. The Company will use observable market data as inputs into the fair value techniques, as discussed in the determination of Level 2 fair values, to the extent it is available, but is also required to use a certain amount of unobservable judgment due to the illiquid nature of the securities involved. Unobservable judgment reflected in the Company’s matrix model accounts for estimates of additional spread required by market participants for factors such as issue size, structural complexity, high bond coupon or other unique features. These matrix-priced securities are reported as Level 2 or Level 3, depending on the significance of the impact of unobservable judgment on the security’s value. Additionally, the Company may obtain non-binding broker quotes which are reported as Level 3. Equity Securities Level 1 consists of publicly traded securities, including exchange traded funds, valued at quoted market prices. Level 2 includes securities that are valued using pricing for similar securities and pricing models that incorporate observable inputs. Level 3 consists of common or preferred stock of private companies for which observable inputs are not available. The Company utilizes a third party pricing service for the valuation of the majority of its equity securities and receives one quote for each equity security. When quoted market prices in an active market are available, they are provided by the pricing service as the fair value and such values are classified as Level 1. The Company holds certain equity securities that have been issued by privately-held entities that do not have an active market and for which the pricing service cannot provide fair values. Generally, the Company estimates fair value for these securities based on the issuer’s book value and market multiples and reports them as Level 3. Additionally, the Company may obtain non-binding broker quotes which are reported as Level 3. Other Investments Other investments primarily include mortgage participations, limited partnerships not subject to equity method of accounting, and overseas trust funds required in connection with the Company’s Lloyd’s business (currently held-for-sale). The fair values of limited partnerships not subject to the equity method of accounting are based on the net asset value provided by the general partner adjusted for recent financial information and are excluded from the fair value hierarchy. Fair values of overseas trust funds are provided by the investment manager based on quoted prices for similar instruments in active markets and are reported as Level 2. The estimated fair value of the financial instruments, including our Chaucer business held-for-sale, were as follows: September 30, 2018 December 31, 2017 Carrying Fair Carrying Fair (in millions) Value Value Value Value Financial Instruments carried at (1) Fair Value through AOCI: Fixed maturities $ 7,899.5 $ 7,899.5 $ 7,779.7 $ 7,779.7 Equity securities — — 576.5 576.5 Other investments — — 3.6 3.6 Fair Value through Net Income: Equity securities 575.0 575.0 — — Other investments 285.8 285.8 122.8 122.8 Amortized Cost/Cost: Other investments 403.1 403.7 512.8 518.3 Cash and cash equivalents 251.3 251.3 376.4 376.4 Total financial instruments, including held-for-sale 9,414.7 9,415.3 9,371.8 9,377.3 Financial instruments, held-for-sale (Chaucer) 2,056.8 2,056.8 2,232.0 2,232.0 Total financial instruments, excluding held-for-sale $ 7,357.9 $ 7,358.5 $ 7,139.8 $ 7,145.3 Financial Liabilities carried at: Amortized Cost: Debt $ 777.6 $ 823.9 $ 786.9 $ 865.7 (1) Due to the adoption of ASU No. 2016-01, certain classifications are not comparable to the prior year. See Note 2 – “New Accounting Pronouncements”. The Company has processes designed to ensure that the values received from its third party pricing service are accurately recorded, that the data inputs and valuation approaches and techniques utilized are appropriate and consistently applied, and that the assumptions are reasonable and consistent with the objective of determining fair value. The Company performs a review of the fair value hierarchy classifications and of prices received from its pricing service on a quarterly basis. The Company reviews the pricing services’ policies describing its methodology, processes, practices and inputs, including various financial models used to value securities. Also, the Company reviews the portfolio pricing, including a process for which securities with changes in prices that exceed a defined threshold are verified to independent sources, if available. If upon review, the Company is not satisfied with the validity of a given price, a pricing challenge would be submitted to the pricing service along with supporting documentation for its review. The Company does not adjust quotes or prices obtained from the pricing service unless the pricing service agrees with the Company’s challenge. During 2018 and 2017, the Company did not adjust any prices received from its pricing service. Changes in the observability of valuation inputs may result in a reclassification of certain financial assets or liabilities within the fair value hierarchy. Reclassifications between levels of the fair value hierarchy are reported as of the beginning of the period in which the reclassification occurs. As previously discussed, the Company utilizes a third party pricing service for the valuation of the majority of its fixed maturities and equity securities. The pricing service has indicated that it will only produce an estimate of fair value if there is objectively verifiable information to produce a valuation. If the pricing service discontinues pricing an investment, the Company will use observable market data to the extent it is available, but may also be required to make assumptions for market based inputs that are unavailable due to market conditions. The following tables provide, for each hierarchy level, the Company’s assets that were measured at fair value on a recurring basis, including those of our Chaucer business which is held-for-sale.

During the three and nine months ended September 30, 2017, an equity security was transferred from Level 3 to Level 1 upon the availability of pricing from the third party pricing service. There were no transfers between Level 1 and Level 2 in 2018 and 2017. There were no Level 3 liabilities held by the Company in 2018 and 2017. The following table provides quantitative information about the significant unobservable inputs used by the Company in the fair value measurements of Level 3 assets, including our Chaucer business held-for-sale. Where discounted cash flows were used in the valuation of fixed maturities, the internally-developed discount rate was adjusted by the significant unobservable inputs shown in the table. The table includes $2.2 million of municipal fixed maturities at September 30, 2018 and December 31, 2017 that are held for sale.

Segment Reporting [Abstract] | |
Segment Information | 9. Segment Information The Company’s primary business operations include insurance products and services provided through three operating segments: Commercial Lines, Personal Lines and Other. Commercial Lines includes commercial multiple peril, commercial automobile, workers’ compensation, and other commercial coverages, such as inland marine, specialty program business, management and professional liability, surety and specialty property. Personal Lines includes personal automobile, homeowners and other personal coverages. Included in the Other segment are Opus Investment Management, Inc., which markets investment management services to institutions, pension funds and other organizations; earnings on holding company assets; holding company and other expenses, including certain costs associated with retirement benefits due to the Company’s former life insurance employees and agents; and, a run-off voluntary pools business. On September 13, 2018, the Company entered into a definitive agreement to sell Chaucer. Accordingly, as of September 30, 2018 and for all prior periods, Chaucer’s results have been classified as Discontinued Operations in the Consolidated Statements of Income and its assets and liabilities have been classified as held-for-sale in the Consolidated Balance Sheets (see Note 3 – “Discontinued Operations”). Certain ongoing expenses have been reclassified from Chaucer to the other three operating segments. The separate financial information is presented consistent with the way results are regularly evaluated by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company reports interest expense related to debt separately from the earnings of its operating segments. This consists of interest on the Company’s senior debentures, subordinated debentures, collateralized borrowings with the Federal Home Loan Bank of Boston, and letter of credit facility. Management evaluates the results of the aforementioned segments based on operating income before taxes, excluding interest expense on debt. Operating income before taxes excludes certain items which are included in net income, such as net realized and unrealized investment gains and losses. Such gains and losses are excluded since they are determined by interest rates, financial markets and the timing of sales. Also, operating income before taxes excludes net gains and losses on disposals of businesses, gains and losses related to the repayment of debt, discontinued operations, costs to acquire businesses, restructuring costs, the cumulative effect of accounting changes and certain other items. Although the items excluded from operating income before taxes may be important components in understanding and assessing the Company’s overall financial performance, management believes that the presentation of operating income before taxes enhances an investor’s understanding of the Company’s results of operations by highlighting net income attributable to the core operations of the business. However, operating income before taxes should not be construed as a substitute for income before income taxes and operating income should not be construed as a substitute for net income. Summarized below is financial information with respect to the Company’s business segments.

The vesting of these stock units is based on the relative total shareholder return (“TSR”) of the Company. This metric is generally based on relative TSR for a three-year period as compared to a pre-selected group of property and casualty companies. The fair value of market-based awards was estimated at the date of grant using a valuation model. These units have the potential to range from 0% to 150% of the shares disclosed. Included in the amount granted above in 2018 and 2017 are 3,115 shares and 5,881 shares, respectively, related to market-based awards that achieved a payout in excess of 100%. These awards vested in the first quarters of 2018 and 2017, respectively. Performance-based restricted stock units are based upon the achievement of the performance metric at 100%. These units have the potential to range from 0% to 200% of the shares disclosed, which varies based on grant year and individual participation level. Increases above the 100% target level are reflected as granted in the period in which performance-based stock unit goals are achieved. Decreases below the 100% target level are reflected as forfeited. There were no awards vested in 2018 and 2017 at a level greater than 100%. |

Liabilities For Outstanding Claims, Losses And Loss Adjustment Expenses | 12. Liabilities for Outstanding Claims, Losses and Loss Adjustment Expenses Reserve Rollforward and Prior Year Development The Company regularly updates its reserve estimates as new information becomes available and further events occur which may impact the resolution of unsettled claims. Reserve adjustments are reflected in results of operations as adjustments to losses and LAE. Often these adjustments are recognized in periods subsequent to the period in which the underlying policy was written and loss event occurred. These types of subsequent adjustments are described as “prior years’ loss reserves”. Such development can be either favorable or unfavorable to the Company’s financial results and may vary by line of business.

In addition, lower than expected losses in workers’ compensation of $14.2 million and other commercial lines of $14.0 million was partially offset by higher than expected losses in our commercial and personal automobile lines of $22.8 million and, to a lesser extent, in our homeowners line. Within other commercial lines, lower than expected losses in our professional and management liability and monoline general liability lines was partially offset by higher than expected losses in AIX programs and business classes which have been terminated. 2017 For the nine months ended September 30, 2017, net favorable loss and LAE development was $0.3 million, primarily as a result of favorable catastrophe development related to the 2016 hurricane Matthew. |

Commitments and Contingencies | 13. Commitments and Contingencies Legal Proceedings Durand Litigation On March 12, 2007, a putative class action suit captioned Jennifer A. Durand v. The Hanover Insurance Group, Inc., and The Allmerica Financial Cash Balance Pension Plan The plaintiff filed an Amended Complaint adding two new named plaintiffs and additional claims on December 11, 2009. Two of the three new claims set forth in the Amended Complaint were dismissed by the District Court, which action was upheld in November 2015 by the U.S. Court of Appeals, Sixth Circuit. The District Court, however, did allow to stand the new claim in the Amended Complaint for breach of fiduciary duty and failure to meet notice requirements arising under the Employee Retirement Income Security Act of 1974 (“ERISA”) from the various interest crediting and lump sum distribution matters of which plaintiffs complain, but only as to plaintiffs’ “whipsaw” claim that remained in the case. On December 17, 2013, the Court entered an order certifying a class to bring “whipsaw” and related breach of fiduciary duty claims consisting of all persons who received a lump sum distribution between March 1, 1997 and December 31, 2003. On February 16, 2018, the Court entered an order limiting the claims of those participants who received lump sum distributions prior to March 13, 2002 to alleged violations of ERISA’s disclosure requirements and breaches of fiduciary duty. Subsequently, the parties entered into settlement discussions and have reached a settlement in principle on major terms, which is subject to agreement on certain other terms, written documentation, and Court approval. Provided the parties are able to finalize such settlement on substantially the terms agreed upon in principle and obtain the necessary Court approval, the Company does not believe the resulting settlement amount will be material to its financial position or have a material effect on its results of operations. Other Matters The Company has been named a defendant in various other legal proceedings arising in the normal course of business. In addition, the Company is involved, from time to time, in examinations, investigations and proceedings by governmental and self-regulatory agencies. The potential outcome of any such action or regulatory proceedings in which the Company has been named a defendant or the subject of an inquiry or investigation, and its ultimate liability, if any, from such action or regulatory proceedings, is difficult to predict at this time. The ultimate resolutions of such proceedings are not expected to have a material effect on its financial position, although they could have a material effect on the results of operations for a particular quarter or annual period. Residual Markets The Company is required to participate in residual markets in various states, which generally pertain to high risk insureds, disrupted markets or lines of business or geographic areas where rates are regarded as excessive. The results of the residual markets are not subject to the predictability associated with the Company’s own managed business, and are significant to both the personal and commercial automobile lines of business and the workers’ compensation line of business. |
