NOTE 1 Summary of Significant Accounting Policies and Going Concern

A. Accounting Practices

The financial statements of The Hanover Insurance Company (“the Company”) are presented on the basis of accounting practices prescribed or permitted by the State of New Hampshire Insurance Department.

The State of New Hampshire Insurance Department recognizes only statutory accounting practices prescribed or permitted by the State of New Hampshire for determining and reporting the financial condition and results of operations of an insurance company, for determining its solvency under the New Hampshire Insurance Law. The National Association of Insurance Commissioners (“NAIC”) “Accounting Practices and Procedures Manual” (“NAIC SAP”) has been adopted as a component of prescribed or permitted practices by the State of New Hampshire. The State has not adopted any prescribed accounting practices that differ from those found in NAIC SAP.

A reconciliation of the Company’s net income and capital and surplus between NAIC SAP and practices prescribed and permitted by the State of New Hampshire is shown below:

B. Use of Estimates in the Preparation of the Financial Statements

The preparation of financial statements in conformity with Statutory Accounting Principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities. It also requires disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates.

C. Accounting Policy

(1) Short-term investments are stated at amortized cost.

(2) Bonds not backed by loans are stated at either amortized cost or fair value, using the scientific interest method, in accordance with the NAIC Purposes and Procedures of the Securities Valuation Office ("SVO").

(3,4) Preferred stocks that are subject to a 100% mandatory sinking fund are carried at amortized cost. All other preferred stocks and common stocks are carried at fair value, except investments in stocks of unconsolidated subsidiaries and affiliates in which the Company has an interest of 10% or more are carried using the equity method.

(5) Mortgage loans on real estate are stated at unpaid principal balances net of unamortized discounts, premiums, and other adjustments. Mortgage loans are reduced for losses expected by management to be realized on transfers of mortgage loans to real estate (upon foreclosure), on the disposition or settlement of mortgage loans and on mortgage loans which the Company believes may not be collectible in full. In determining the amount of loss, management considers, among other things, the estimated fair value of the underlying collateral.

(6) Loan-backed securities are stated at either amortized cost or fair value, in accordance with the NAIC Purposes and Procedures of the SVO.

(7) The Company owns 100% of the common stock of Allmerica Financial Alliance Insurance Company (“AFAIC”), Allmerica Financial Benefit Insurance Company (“AFBIC”), The Hanover American Insurance Company (“American”), The Hanover Atlantic Insurance Company Ltd. (“Atlantic”), The Hanover Casualty Company (“Hanover Casualty”), Massachusetts Bay Insurance Company (“Mass Bay”), Citizens Insurance Company of America (“CICA”), Citizens Insurance Company of the Midwest (“CICM”), Citizens Insurance Company of Ohio (“CICO”), The Hanover New Jersey Insurance Company (“New Jersey”), Verlan Fire Insurance Company (“Verlan”), The Hanover National Insurance Company (“National”), Campmed Casualty and Indemnity Company, Inc. (“Campmed”), and Nova Casualty Company ("NOVA"), all of which are insurance subsidiaries. The Company owns 100% of the common stock of Professionals Direct Inc. (“PDI”), AIX, Inc. (“AIX”), and Allmerica Plus Insurance Agency (“APIA”), which are non-insurance subsidiaries. All subsidiaries are carried using the equity method.

(8) Other invested assets, including investments in trusts, are recorded using the equity method in accordance with the Statement of Statutory Accounting Principles ("SSAP") No. 48, "Joint Ventures, Partnerships and Limited Liability Companies". Investments in affiliated entities are recorded based on its underlying audited GAAP equity balances in accordance with the SSAP 97, "Investments in Subsidiary, Controlled, and Affiliated Entities, A Replacement of SSAP 88". Commercial mortgage loan participations are recorded at outstanding principal balance of the loan per SSAP 21, "Other Admitted Assets".

(9) The Company has not entered into derivative contracts.

(10) The Company does utilize anticipated investment income as a factor in the premium deficiency calculation.

(11) Unpaid losses and loss adjustment expenses include an amount determined from individual case estimates and loss reports and an amount, based on past experience, for losses incurred but not reported (“IBNR”). Such liabilities are necessarily based on assumptions and estimates and while management believes the amount is adequate, the ultimate liability may be in excess of or less than the amount provided. The methods for making such estimates and for establishing the resulting liabilities are continually reviewed and any adjustments are reflected in the period determined.

(12) The Company has not modified its capitalization policy from the prior year.

(13) The Company does not write major medical insurance with prescription drug coverage.

c. Not applicable

(3) The reporting entity's policy is to recognize transfers in and transfers out as of the actual date of the event or change in circumstances that caused the transfer.

(4) For fair value measurements categorized within Level 2 of the fair value hierarchy, fair values of bonds are obtained by a quoted market price if available, otherwise, fair values are estimated using independent pricing sources or internally developed pricing models using discounted cash flow analyses.

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 applications based on a market approach. Inputs into the fair value pricing applications which are 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 of the security, such as maturity date, coupon, mandatory principal payment dates, frequency of interest and principal payments and optional principal redemption features. Inputs into the fair value applications that are unique by asset class include, but are not limited to:

• U.S. government – determination of direct versus indirect government support and whether any contingencies exist with respect to the timely payment of principal and interest.

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 corporate bonds and certain other bonds 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 or broker quotes. The Company will use observable market data 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. Additionally, the Company may obtain nonbinding broker quotes which are reported as Level 3.

Fair values of common and preferred stocks are based on SVO valuation, if available. If SVO valuations are not available, quoted market prices are used. If neither SVO prices nor quoted market prices are available, fair values are estimated using independent pricing sources or internally developed pricing models using discounted cash flow analyses.

Level 2 includes securities that are valued using pricing for similar securities and pricing models that incorporate observable inputs. Level 3 consists of common stock of private companies for which observable inputs are not available. The Company uses a third party pricing service for the valuation of the majority of its equity securities. 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. Generally, all prices provided by the pricing service except quoted market prices, are reported as Level 2. Occasionally, the Company may obtain nonbinding broker quotes which are reported as Level 3.

IBNR loss and loss adjustment expense reserves are allocated to the Company based on the proportion of the Company’s earned premiums and case loss reserves relative to other affiliates in The Hanover Insurance Group. Fluctuations by affiliate and state may occur as a result of this re-estimation process.

The Company elected to use rounding to the nearest dollar in reporting amounts in the Statement, except as otherwise directed by instructions.

At the end of the current period and prior year, the Company had admitted assets of $1,176,464,059 and $1,144,443,223, respectively, in premiums receivable due from policyholders, agents and ceding insurers. The Company routinely assesses the collectability of these receivables. Based upon Company experience, any uncollectible premiums receivable at the end of the current period are not expected to exceed the non admitted amounts totaling $24,067,619 and, therefore, no additional provision for uncollectible amounts has been recorded. The potential for any additional loss is not believed to be material to the Company’s financial position.

The Company reported $130,399,286 on Page 2 Line 15.1 for Agents’ balances or Uncollected Premiums. There are no agents’ balances or uncollected premiums due from controlled or controlling persons.

A. The estimated cost of loss and loss adjustment expenses (“LAE”) attributable to insured events of prior year’s decreased by $13,915,000 during the current year. The savings of $13,915,000 is 0.35% of unpaid losses and LAE of $3,991,508,445 as of December 31, 2020. The favorable loss development is primarily due to lower than expected losses in workers compensation and commercial multi peril lines of business. Increases or decreases generally occur as a result of claim settlements during the current year, and as additional information is received regarding individual claims, causing changes from the original estimates of the costs of these claims. Recent loss development trends are also taken into account evaluating the overall adequacy of unpaid losses and LAE.

B. There were no significant changes in methodologies and assumptions used in calculating the liability for unpaid property and casualty losses and loss adjustment expenses.
