Nature of Operations	'
	Note 1.  Nature of Operations
	Erie Indemnity Company (“Indemnity”) is a publicly held Pennsylvania business corporation that has been the managing attorney-in-fact for the subscribers (policyholders) at the Erie Insurance Exchange (“Exchange”) since 1925.  The Exchange is a subscriber-owned, Pennsylvania-domiciled reciprocal insurer that writes property and casualty insurance.
	Indemnity’s primary function is to perform certain services for the Exchange relating to the sales, underwriting and issuance of policies on behalf of the Exchange.  This is done in accordance with a subscriber’s agreement (a limited power of attorney) executed by each subscriber (policyholder), which appoints Indemnity as their common attorney-in-fact to transact business on their behalf and to manage the affairs of the Exchange.  Pursuant to the subscriber’s agreement and for its services as attorney-in-fact, Indemnity earns a management fee calculated as a percentage of the direct premiums written by the Exchange and the other members of the Property and Casualty Group (defined below), which are assumed by the Exchange under an intercompany pooling arrangement.
	Indemnity has the power to direct the activities of the Exchange that most significantly impact the Exchange’s economic performance by acting as the common attorney-in-fact and decision maker for the subscribers (policyholders) at the Exchange.
	The Exchange, together with its wholly owned subsidiaries, Erie Insurance Company (“EIC”), Erie Insurance Company of New York (“ENY”), Erie Insurance Property and Casualty Company (“EPC”), and Flagship City Insurance Company (“Flagship”), operate as a property and casualty insurer and are collectively referred to as the “Property and Casualty Group”.  The Property and Casualty Group operates in 11 Midwestern, Mid-Atlantic and Southeastern states and the District of Columbia.
	Erie Family Life Insurance Company (“EFL”), a wholly owned subsidiary of the Exchange, operates as a life insurer that underwrites and sells individual and group life insurance policies and fixed annuities.
	Indemnity plans to expand the property and casualty and life insurance operations of the Erie Insurance Group into the Commonwealth of Kentucky by the first quarter of 2015 or earlier if possible.
	All property and casualty and life insurance operations are owned by the Exchange and Indemnity functions solely as the management company.
	The consolidated financial statements of Erie Indemnity Company reflect the results of Indemnity and its variable interest entity, the Exchange, which we refer to collectively as the “Erie Insurance Group” (“we,” “us,” “our”).
	“Indemnity shareholder interest” refers to the interest in Erie Indemnity Company owned by the Class A and Class B shareholders.  “Noncontrolling interest” refers to the interest in the Erie Insurance Exchange held for the subscribers (policyholders).

Accounting Policies [Abstract]	'
Significant Accounting Policies	'
	Note 2.  Significant Accounting Policies
	Basis of presentation
	The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Indemnity together with its affiliate companies in which Indemnity holds a majority voting or economic interest.
	Use of estimates
	The preparation of financial statements in conformity with GAAP requires us 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 amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.
	In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of our financial position, results of operations, and cash flows for the interim periods have been included.  Operating results for the six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ended December 31, 2014.  The accompanying consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission on February 27, 2014.
	Principles of consolidation
	We consolidate the Exchange as a variable interest entity for which Indemnity is the primary beneficiary.  All intercompany accounts and transactions have been eliminated in consolidation.  The required presentation of noncontrolling interests is reflected in the consolidated financial statements.  Noncontrolling interests represent the ownership interests of the Exchange, all of which are held by parties other than Indemnity (i.e. the Exchange’s subscribers (policyholders)).  Noncontrolling interests also include the Exchange subscribers’ ownership interest in EFL.
	Presentation of assets and liabilities – While the assets of the Exchange are presented separately in the Consolidated Statements of Financial Position, the Exchange’s assets can only be used to satisfy the Exchange’s liabilities or for other unrestricted activities.  Accounting Standards Codification (“ASC”) 810, Consolidation, does not require separate presentation of the Exchange’s assets; however, because the shareholders of Indemnity have no rights to the assets of the Exchange and, conversely, the Exchange has no rights to the assets of Indemnity, we have presented the invested assets of the Exchange separately on the Consolidated Statements of Financial Position along with the remaining consolidated assets reflecting the Exchange’s portion parenthetically.  Liabilities are required under ASC 810, Consolidation, to be presented separately for the Exchange on the Consolidated Statements of Financial Position as the Exchange’s creditors do not have recourse to the general credit of Indemnity.
	Rights of shareholders of Indemnity and subscribers (policyholders) of the Exchange – The shareholders of Indemnity, through the management fee, have a controlling financial interest in the Exchange; however, they have no other rights to or obligations arising from assets and liabilities of the Exchange.  The shareholders of Indemnity own its equity but have no rights or interest in the Exchange’s (noncontrolling interest) income or equity.  The noncontrolling interest equity represents the Exchange’s equity held for the interest of its subscribers (policyholders), who have no rights or interest in the Indemnity shareholder interest income or equity.
	All intercompany assets, liabilities, revenues, and expenses between Indemnity and the Exchange have been eliminated in the Consolidated Financial Statements.
	Pending accounting pronouncements
	In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects.  This guidance permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met.  Generally, investors in qualified affordable housing project investments expect to receive substantially all of their return through the receipt of tax credits and other tax benefits.  ASU No. 2014-01 allows for the recording of the investment performance net of taxes as a component of income tax expense to more fairly represent the economics of the investments and provide users with a better understanding of the returns from such investments.  The qualifications to make this accounting election were also made less restrictive.  ASU No. 2014-01 is effective for annual and interim periods beginning after December 15, 2014, with early adoption permitted.  While we are currently evaluating whether to make the accounting election and whether the election would be made for early adoption, such election is not expected to have a material impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU No. 2014-09 clarifies the principles for recognizing revenue and provides a common revenue standard for GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Insurance contracts are not within the scope of this guidance. ASU No. 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early application is not permitted. We do not expect the adoption of ASU No. 2014-09 related to the management fee and service agreement revenue to have a material impact on our consolidated financial statements.

Indemnity Earnings Per Share	'
	Note 3.  Indemnity Earnings Per Share
	Class A and Class B basic earnings per share and Class B diluted earnings per share are calculated under the two-class method. The two-class method allocates earnings to each class of stock based upon its dividend rights.  Class B shares are convertible into Class A shares at a conversion ratio of 2,400 to 1. See Note 11. “Indemnity Capital Stock”.
	Class A diluted earnings per share are calculated under the if-converted method, which reflects the conversion of Class B shares to Class A shares. Diluted earnings per share calculations include the effect of any potential common shares. Potential common shares include outstanding vested and not yet vested awards related to our outside directors’ stock compensation plan and any employee stock based awards.
	A reconciliation of the numerators and denominators used in the basic and diluted per-share computations is presented as follows for each class of Indemnity common stock:

Variable Interest Entity [Abstract]	'
Variable Interest Entity	'
	Note 4.  Variable Interest Entity
	Erie Insurance Exchange
	The Exchange is a reciprocal insurance exchange domiciled in Pennsylvania, for which Indemnity serves as attorney-in-fact.  Indemnity holds a variable interest in the Exchange due to the absence of decision-making capabilities by the equity owners (subscribers/policyholders) of the Exchange and due to the significance of the management fee the Exchange pays to Indemnity as its decision maker.  As a result, Indemnity is deemed to have a controlling financial interest in the Exchange and is considered to be its primary beneficiary.
	Consolidation of the Exchange’s financial results is required given the significance of the management fee to the Exchange and because Indemnity has the power to direct the activities of the Exchange that most significantly impact the Exchange’s economic performance.  The Exchange’s anticipated economic performance is the product of its underwriting results combined with its investment results.  The fees paid to Indemnity under the subscriber’s agreement impact the anticipated economic performance attributable to the Exchange’s results.  Indemnity earns a management fee from the Exchange for the services it provides as attorney-in-fact.  Indemnity’s management fee revenues are based upon all premiums written or assumed by the Exchange.  Indemnity’s Board of Directors determines the management fee rate to be paid by the Exchange to Indemnity.  This rate cannot exceed 25% of the direct and assumed written premiums of the Exchange, as defined by the subscriber’s agreement signed by each policyholder.  Management fee revenues and management fee expenses are eliminated upon consolidation.
	The shareholders of Indemnity have no rights to the assets of the Exchange and no obligations arising from the liabilities of the Exchange.  Indemnity has no obligation related to any underwriting and/or investment losses experienced by the Exchange.  Indemnity would, however, be adversely impacted if the Exchange incurred significant underwriting and/or investment losses.  If the surplus of the Exchange were to decline significantly from its current level, its financial strength ratings could be reduced and, as a consequence, the Exchange could find it more difficult to retain its existing business and attract new business.  A decline in the business of the Exchange would have an adverse effect on the amount of the management fees Indemnity receives.  In addition, a decline in the surplus of the Exchange from its current level may impact the management fee rate received by Indemnity.  Indemnity also has an exposure to a concentration of credit risk related to the unsecured receivables due from the Exchange for its management fee. If any of these events occurred, Indemnity’s financial position, financial performance, and/or cash flows could be adversely impacted.
	All property and casualty and life insurance operations are owned by the Exchange, and Indemnity functions solely as the management company.
	Indemnity has not provided financial or other support to the Exchange for any of the reporting periods presented.  At June 30, 2014, there are no explicit or implicit arrangements that would require Indemnity to provide future financial support to the Exchange.  Indemnity is not liable if the Exchange was to be in violation of its debt covenants or was unable to meet its obligation for unfunded commitments to limited partnerships.

Segment Reporting [Abstract]	'
Segment Information	'
	Note 5. Segment Information
	Our reportable segments include management operations, property and casualty insurance operations, life insurance operations, and investment operations.  Accounting policies for segments are the same as those described in the summary of significant accounting policies.  See Item 8. “Financial Statements and Supplementary Data, Note 2. Significant Accounting Policies,” in our Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission on February 27, 2014.  Assets are not allocated to the segments, but rather, are reviewed in total for purposes of decision-making.  No single customer or agent provides 10% or more of revenues.
	Management operations
	Our management operations segment consists of Indemnity serving as attorney-in-fact for the Exchange.  Indemnity operates in this capacity solely for the Exchange.  We evaluate profitability of our management operations segment principally on the gross margin from management operations.  Indemnity earns a management fee from the Exchange for providing sales, underwriting, and policy issuance services.  Management fee revenue, which is eliminated upon consolidation, is calculated as a percentage not to exceed 25% of all the direct premiums written by the Exchange and the other members of the Property and Casualty Group, which are assumed by the Exchange under an intercompany pooling arrangement.  The Property and Casualty Group issues policies with annual terms only.  Management fees are recorded upon policy issuance or renewal, as substantially all of the services required to be performed by Indemnity have been satisfied at that time.  Certain activities are performed and related costs are incurred by us subsequent to policy issuance in connection with the services provided to the Exchange; however, these activities are inconsequential and perfunctory.  Although these management fee revenues and expenses are eliminated upon consolidation, the amount of the fee directly impacts the allocation of our consolidated net income between the noncontrolling interest, which bears the management fee expense and represents the interests of the Exchange subscribers (policyholders), and Indemnity’s interest, which earns the management fee revenue and represents the Indemnity shareholder interest in net income.
	Property and casualty insurance operations
	Our property and casualty insurance operations segment includes personal and commercial lines.  Personal lines consist primarily of personal auto and homeowners and are marketed to individuals.  Commercial lines consist primarily of commercial multi-peril, commercial auto, and workers compensation and are marketed to small- and medium-sized businesses.  Our property and casualty policies are sold by independent agents.  Our property and casualty insurance underwriting operations are conducted through the Exchange and its subsidiaries and include assumed voluntary reinsurance from nonaffiliated domestic and foreign sources, assumed involuntary, and ceded reinsurance business.  The Exchange exited the assumed voluntary reinsurance business effective December 31, 2003, and therefore unaffiliated assumed voluntary reinsurance includes only run-off activity of the previously assumed voluntary reinsurance business.  We evaluate profitability of the property and casualty insurance operations principally based upon net underwriting results represented by the combined ratio.
	Life insurance operations
	Our life insurance operations segment includes traditional and universal life insurance products and fixed annuities marketed to individuals using the same independent agency force utilized by our property and casualty insurance operations.  We evaluate profitability of the life insurance segment principally based upon segment net income, including investments, which for segment purposes are reflected in the investment operations segment.  At the same time, we recognize that investment-related income is integral to the evaluation of the life insurance segment because of the long duration of life products.  For the second quarters of 2014 and 2013, investment activities on life insurance related assets generated revenues of $24 million and $26 million, respectively, resulting in EFL reporting income before income taxes of $10 million and $13 million, respectively, before intercompany eliminations. For the six months ended June 30, 2014 and June 30, 2013, investment activities on life insurance related assets generated revenues of $53 million and $52 million, respectively, resulting in EFL reporting income before income taxes of $23 million and $24 million, respectively, before intercompany eliminations.
	Investment operations
	The investment operations segment includes returns from our fixed maturity, equity security and limited partnership investment portfolios to support our underwriting business.  The Indemnity and Exchange portfolios are managed with the objective of maximizing after-tax returns on a risk-adjusted basis, while the EFL portfolio is managed to be closely aligned to its liabilities and to maintain a sufficient yield to meet profitability targets.  Management actively evaluates the portfolios for impairments. We record impairment writedowns on investments in instances where the fair value of the investment is substantially below cost, and we conclude that the decline in fair value is other-than-temporary.  Investment related income for the life operations is included in the investment segment results.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Note 6. Fair Value
	Our available-for-sale and trading securities are recorded at fair value, which is the price that would be received to sell the asset in an orderly transaction between willing market participants as of the measurement date.
	Valuation techniques used to derive the fair value of our available-for-sale and trading securities are based upon observable and unobservable inputs.  Observable inputs reflect market data obtained from independent sources.  Unobservable inputs reflect our own assumptions regarding fair market value for these securities.  Although the majority of our prices are obtained from third party sources, we also perform an internal pricing review for securities with low trading volumes under current market conditions. Financial instruments are categorized based upon the following characteristics or inputs to the valuation techniques:
	•	Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
	•	Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
	•	Level 3 – Unobservable inputs for the asset or liability.
	Estimates of fair values for our investment portfolio are obtained primarily from a nationally recognized pricing service.  Our Level 1 category includes those securities valued using an exchange traded price provided by the pricing service.  The methodologies used by the pricing service that support a Level 2 classification of a financial instrument include multiple verifiable, observable inputs including benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data.  Pricing service valuations for Level 3 securities are based upon proprietary models and are used when observable inputs are not available or in illiquid markets.
	In limited circumstances we adjust the price received from the pricing service when, in our judgment, a better reflection of fair value is available based upon corroborating information and our knowledge and monitoring of market conditions such as a disparity in price of comparable securities and/or non-binding broker quotes.  In other circumstances, certain securities are internally priced because prices are not provided by the pricing service.
	We perform continuous reviews of the prices obtained from the pricing service.  This includes evaluating the methodology and inputs used by the pricing service to ensure that we determine the proper classification level of the financial instrument.  Price variances, including large periodic changes, are investigated and corroborated by market data.  We have reviewed the pricing methodologies of our pricing service as well as other observable inputs, such as data, and transaction volumes and believe that their prices adequately consider market activity in determining fair value.  Our review process continues to evolve based upon accounting guidance and requirements.
	When a price from the pricing service is not available, values are determined by obtaining broker/dealer quotes and/or market comparables.  When available, we obtain multiple quotes for the same security.  The ultimate value for these securities is determined based upon our best estimate of fair value using corroborating market information.  Our evaluation includes the consideration of benchmark yields, reported trades, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data.
	For certain securities in an illiquid market, there may be no prices available from a pricing service and no comparable market quotes available.  In these situations, we value the security using an internally-developed, risk-adjusted discounted cash flow model.

	(1)          Other investments measured at fair value represent four real estate funds included on the balance sheet as limited partnership investments that are reported under the fair value option. These investments can never be redeemed with the funds. Instead, distributions are received when liquidation of the underlying assets of the funds occur. It is estimated that the underlying assets will generally be liquidated between 5 and 10 years from the inception of the funds. The fair value of these investments is based on the net asset value (NAV) information provided by the general partner. Fair value is based on our proportionate share of the NAV based on the most recent partners' capital statements received from the general partners, which is generally one quarter prior to our balance sheet date. These values are then analyzed to determine if they represent the NAV at our balance sheet date, with adjustment being made where appropriate. We consider observable market data and perform a review validating the appropriateness of the NAV at each balance sheet date. It is likely that all of the investments will be redeemed at a future date for an amount different than the NAV of our ownership interest in partners' capital as of June 30, 2014. During the six months ended June 30, 2014, Indemnity made no contributions and received distributions totaling $1.8 million, and the Exchange made no contributions and received distributions totaling $6.9 million for these investments. As of June 30, 2014, the amount of unfunded commitments related to the investments was $1.5 million for Indemnity and $4.5 million for the Exchange.

-1	Corporate debt securities – The unobservable input used in the fair value measurement of certain corporate debt securities is the likelihood of repayment by the underlying entity when there is no market for trading these securities.  When available, we obtain non-binding broker quotes to value such securities. When a non-binding broker quote was the only input available, it was considered unobservable.
-2	Collateralized-debt-obligation securities – The unobservable inputs used in the fair value measurement of certain collateralized-debt-obligation securities are the repayment at maturity of underlying collateral available to pay note holders, the projected maturity of the underlying security, and a discount rate appropriate for the security.  Significant changes in any of those inputs in isolation would result in a significantly higher or lower fair value measurement.  Generally, a change in the assumption used for the performance of the underlying collateral is accompanied by an opposite change in the maturity and a directionally opposite change in the discount rate used to value the security.
-3	Common stock investments and Corporate debt securities – The unobservable inputs used in the fair value measurement of direct private equity common stock investments and certain corporate debt securities are comparable private transaction earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples, the average EBITDA multiple for comparable publicly traded companies and the amount of discount applied to the price due to the illiquidity of the securities being valued.  Significant changes in any of those inputs in isolation could result in a significantly higher or lower fair value measurement.
-4	Other investments – Other investments represent certain limited partnerships that are recorded at fair value and are based upon net asset value (NAV) provided by the general partner where the unobservable inputs are not reasonably available to us.
-5	Nonredeemable preferred stock - The unobservable input used in the fair value measurement of a private nonredeemable preferred stock security is the price to sales ratio for comparable publicly traded companies.
Securities valued using unobservable inputs shown above totaled $162 million at June 30, 2014. In total, Level 3 assets represent less than 1.2% of the total assets measured at fair value on a recurring basis for the Erie Insurance Group.

(1)          Other investments measured at fair value represent four real estate funds included on the balance sheet as limited partnership investments that are reported under the fair value option. These investments can never be redeemed with the funds. Instead, distributions are received when liquidation of the underlying assets of the funds occur. It is estimated that the underlying assets will generally be liquidated between 5 and 10 years from the inception of the funds. The fair value of these investments is based on the net asset value (NAV) information provided by the general partner. Fair value is based on our proportionate share of the NAV based on the most recent partners' capital statements received from the general partners, which is generally one quarter prior to our balance sheet date. These values are then analyzed to determine if they represent the NAV at our balance sheet date, with adjustment being made where appropriate. We consider observable market data and perform a review validating the appropriateness of the NAV at each balance sheet date. It is likely that all of the investments will be redeemed at a future date for an amount different than the NAV of our ownership interest in partners' capital as of December 31, 2013. During the year ended December 31, 2013, Indemnity made no contributions and received distributions totaling $2.4 million, and the Exchange made no contributions and received distributions totaling $21.7 million for these investments. As of December 31, 2013, the amount of unfunded commitments related to the investments was $1.5 million for Indemnity and $4.5 million for the Exchange.

-1	These amounts are reported in the Consolidated Statement of Operations. There is $3 million included in net realized investment gains (losses) and $2 million included in equity in earnings of limited partnerships for the three months ended June 30, 2013 on Level 3 securities.
-2	Transfers in and out of Level 3 are attributable to changes in the availability of market observable information for individual securities within the respective categories. Transfers in and out of levels are recognized at the start of the period.
We review the fair value hierarchy classifications each reporting period.  Transfers between hierarchy levels may occur due to changes in the available market observable inputs.  Transfers in and out of level classifications are reported as having occurred at the beginning of the quarter in which the transfers occurred.
For Indemnity, there were no transfers between Level 1 and Level 2 or between Level 2 and Level 3 for the three months ended June 30, 2013.
For the Exchange, there were no transfers between Level 1 and Level 2 or from Level 2 to Level 3 for the three months ended June 30, 2013. Level 3 to Level 2 transfers totaled $23 million for three fixed maturity holdings. These transfers out of Level 3 were primarily the result of using observable market data to determine the fair value at June 30, 2013.

-1	These amounts are reported in the Consolidated Statement of Operations. There is $(2) million of losses included in net realized investment (losses) and $8 million included in equity in earnings of limited partnerships for the six months ended June 30, 2013 on Level 3 securities.
-2	Transfers in and out of Level 3 are attributable to changes in the availability of market observable information for individual securities within the respective categories. Transfers in and out of levels are recognized at the start of the period.
For Indemnity, there were no Level 1 to Level 2 transfers for the six months ended June 30, 2013. Level 2 to Level 1 transfers totaled $1 million, due to trading activity levels related to one preferred stock holding, and there were no transfers between Levels 2 and 3.
For the Exchange, Level 1 to Level 2 transfers totaled $5 million and Level 2 to Level 1 transfers totaled $44 million due to trading activity levels related to one preferred stock holding and five preferred stock holdings, respectively, for the six months ended June 30, 2013. Level 2 to Level 3 transfers totaled $18 million for five fixed maturity holdings and Level 3 to Level 2 transfers totaled $18 million for two fixed maturity holdings. These transfers in and out of Level 3 were primarily the result of using non-binding and binding broker quotes, respectively, to determine the fair value at June 30, 2013.

The above securities for Indemnity and the Exchange have been evaluated and determined to be temporary impairments for which we expect to recover our entire principal plus interest.  The primary components of this analysis include a general review of market conditions and financial performance of the issuer along with the extent and duration at which fair value is less than cost.  Any securities that we intend to sell or will more likely than not be required to sell before recovery are included in other-than-temporary impairments with the impairment charges recognized in earnings.

The above securities for Indemnity and the Exchange have been evaluated and determined to be temporary impairments for which we expect to recover our entire principal plus interest.  The primary components of this analysis include a general review of market conditions and financial performance of the issuer along with the extent and duration at which fair value is less than cost.  Any securities that we intend to sell or will more likely than not be required to sell before recovery are included in other-than-temporary impairments with the impairment charges recognized in earnings.

Net impairment losses
Net impairment losses recorded in earnings for Indemnity were $0.1 million for the second quarter and six months ended June 30, 2014 and June 30, 2013. Net impairment losses recorded in earnings for the Exchange were $0.1 million for the second quarter and $0.3 million for the six months ended June 30, 2014, compared to net impairment losses of $1 million for the second quarter and the six months ended June 30, 2013.
In considering if fixed maturity securities were credit-impaired, some of the factors considered include: potential for the default of interest and/or principal, level of subordination, collateral of the issue, compliance with financial covenants, credit ratings and industry conditions.  We have the intent to sell all credit-impaired fixed maturity securities, therefore the entire amount of the impairment charges were included in earnings and no non-credit impairments were recognized in other comprehensive income.
Limited partnerships
Limited partnership investments, excluding certain real estate limited partnerships recorded at fair value, are generally reported on a one-quarter lag, therefore our year-to-date limited partnership results through June 30, 2014 are comprised of partnership financial results for the fourth quarter of 2013 and first quarter of 2014.  Given the lag in reporting, our limited partnership results do not reflect the market conditions of the second quarter of 2014.  Cash contributions made to and distributions received from the partnerships are recorded in the period in which the transaction occurs.
Amounts included in equity in earnings of limited partnerships by method of accounting are included below:

As these investments are generally reported on a one-quarter lag, our limited partnership results through June 30, 2014 include partnership financial results for the fourth quarter of 2013 and the first quarter of 2014.

	As of June 30, 2014, Indemnity has access to a $100 million bank revolving line of credit with a $25 million letter of credit sublimit that expires on November 3, 2018. As of June 30, 2014, a total of $98.2 million remains available under the facility due to $1.8 million outstanding letters of credit, which reduce the availability for letters of credit to $23.2 million.  Indemnity had no borrowings outstanding on its line of credit as of June 30, 2014.  Bonds with a fair value of $113 million were pledged as collateral on the line at June 30, 2014.
	As of June 30, 2014, the Exchange has access to a $300 million bank revolving line of credit with a $25 million letter of credit sublimit that expires on October 25, 2018. As of June 30, 2014, a total of $298.9 million remains available under the facility due to $1.1 million outstanding letters of credit, which reduce the availability for letters of credit to $23.9 million.  The Exchange had no borrowings outstanding on its line of credit as of June 30, 2014.  Bonds with a fair value of $331 million were pledged as collateral on the line at June 30, 2014.
	Both lines have securities pledged as collateral that have no trading restrictions and are reported as available-for-sale fixed maturities in the Consolidated Statements of Financial Position as of June 30, 2014.  The banks require compliance with certain covenants, which include leverage ratios for Indemnity’s line of credit and statutory surplus and risk based capital ratios for the Exchange’s line of credit.  We are in compliance with all covenants at June 30, 2014.

Income Taxes	'
	Note 9.  Income Taxes
	Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns.  Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.
	At June 30, 2014, we recorded a net deferred tax liability of $556 million on our Consolidated Statements of Financial Position.  Of this amount, $1 million is a net deferred tax asset attributable to Indemnity and $557 million is a net deferred tax liability attributable to the Exchange.  There was no deferred tax valuation allowance recorded at June 30, 2014.  Our effective tax rate is calculated after consideration of permanent differences related to our investment revenues.  Given that these amounts represent over 98% of the total permanent differences, the effective tax rate is approximately 35% for both Indemnity and the Exchange when the investment related permanent differences are excluded.

	Note 10.   Postretirement Benefits
	Pension plans
	Our pension plans consist of a noncontributory defined benefit pension plan covering substantially all employees and an unfunded supplemental employee retirement plan for certain members of executive and senior management of the Erie Insurance Group.  The gross liability for postretirement benefits is presented in the Consolidated Statements of Financial Position as part of other liabilities.  A portion of annual expenses related to our postretirement benefit plans is allocated to related entities within the Erie Insurance Group. Although Indemnity is the sponsor of these postretirement plans and records the funded status of these plans, the Exchange and EFL reimburse Indemnity for approximately 55% of the annual benefit expense of these plans, which represents pension benefits for Indemnity employees performing claims and EFL functions.
	Prior to 2003, the employee pension plan purchased annuities from EFL for certain plan participants that were receiving benefit payments under the pension plan. These are nonparticipating annuity contracts under which EFL has unconditionally contracted to provide specified benefits to beneficiaries; however, the pension plan remains the primary obligor to the beneficiaries and a contingent liability, $26 million at June 30, 2014, exists in the event EFL does not honor the annuity contracts.
	The cost of our pension plans are as follows:

Commitments and Contingencies	'
	Note 14.  Commitments and Contingencies
	Indemnity has contractual commitments to invest up to $26 million related to its limited partnership investments at June 30, 2014.  These commitments are split among private equity securities of $11 million, mezzanine debt securities of $9 million, and real estate activities of $6 million.  These commitments will be funded as required by the partnership agreements.
	The Exchange, including EFL, has contractual commitments to invest up to $445 million related to its limited partnership investments at June 30, 2014.  These commitments are split among private equity securities of $146 million, mezzanine debt securities of $173 million, and real estate activities of $126 million.  These commitments will be funded as required by the partnership agreements.
	We are involved in litigation arising in the ordinary course of conducting business.  In accordance with current accounting standards for loss contingencies and based upon information currently known to us, we establish reserves for litigation when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss or range of loss can be reasonably estimated.  When no amount within the range of loss is a better estimate than any other amount, we accrue the minimum amount of the estimable loss.  To the extent that such litigation against us may have an exposure to a loss in excess of the amount we have accrued, we believe that such excess would not be material to our consolidated financial condition, results of operations, or cash flows.  Legal fees are expensed as incurred.  We believe that our accruals for legal proceedings are appropriate and, individually and in the aggregate, are not expected to be material to our consolidated financial condition, operations, or cash flows.
	We review all litigation on an ongoing basis when making accrual and disclosure decisions.  For certain legal proceedings, we cannot reasonably estimate losses or a range of loss, if any, particularly for proceedings that are in their early stages of development or where the plaintiffs seek indeterminate damages.  Various factors, including, but not limited to, the outcome of potentially lengthy discovery and the resolution of important factual questions, may need to be determined before probability can be established or before a loss or range of loss can be reasonably estimated.  If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable.  In the event that a legal proceeding results in a substantial judgment against, or settlement by, us, there can be no assurance that any resulting liability or financial commitment would not have a material adverse effect on the financial condition, results of operations, or cash flows of the Indemnity shareholder interest or the consolidated financial statements of Erie Indemnity Company.
	We are subject to escheatment laws and regulations requiring the identification, reporting and payment to the state of unclaimed or abandoned funds of our policyholders, annuitants, claimants and shareholders. We are also subject to audit and examination for compliance with these requirements.
	In August 2012, we were notified that we would be subject to an audit of our compliance with the unclaimed property laws of a number of jurisdictions both within and outside our operating territory. The audit commenced in April 2013 and is ongoing. Additionally, EFL has been named in a lawsuit filed by the State Treasurer of West Virginia. The Complaint alleges that EFL has failed to comply with the West Virginia Uniform Unclaimed Property Act. EFL filed a motion to dismiss and a favorable decision was rendered in December 2013 with the Court dismissing the Complaint with prejudice. The State Treasurer appealed the dismissal of the lawsuit in January 2014.
	It is probable that ongoing inquiries, audits, and other regulatory activity will result in the payment of additional death claims and escheatment of funds, as well as possible fines. EFL will incur expenses to identify death claims, confirm that benefits are due and notify the beneficiaries. At this time, we are not able to reasonably estimate the possible loss or range of loss related to this issue due to the early stage of development.

Receivables from the Exchange and EFL and concentrations of credit risk – Financial instruments could potentially expose Indemnity to concentrations of credit risk, including unsecured receivables from the Exchange.  A majority of Indemnity’s revenue and receivables are from the Exchange and affiliates.  See also Note 4, “Variable Interest Entity.”
Management fees and expense allocation amounts due from the Exchange were $335 million and $296 million at June 30, 2014 and December 31, 2013, respectively.  The receivable from EFL for expense allocations and interest on the surplus note totaled $4 million at June 30, 2014 and December 31, 2013.
Note receivable from EFL – Indemnity is due $25 million from EFL in the form of a surplus note that was issued in 2003.  The note may be repaid only out of unassigned surplus of EFL.  Both principal and interest payments are subject to prior approval by the Pennsylvania Insurance Commissioner.  The note bears an annual interest rate of 6.7% and will be payable on demand on or after December 31, 2018, with interest scheduled to be paid semi-annually, subject to prior approval by the Pennsylvania Insurance Commissioner.  For each of the six months ended June 30, 2014 and 2013, Indemnity recognized interest income on the note of $0.8 million.

Accounting Policies [Abstract]	'
Basis of presentation	'
	Basis of presentation
	The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Indemnity together with its affiliate companies in which Indemnity holds a majority voting or economic interest.
Use of estimates	'
	Use of estimates
	The preparation of financial statements in conformity with GAAP requires us 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 amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.
	In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of our financial position, results of operations, and cash flows for the interim periods have been included.  Operating results for the six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ended December 31, 2014.  The accompanying consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission on February 27, 2014.
Principles of consolidation	'
	Principles of consolidation
	We consolidate the Exchange as a variable interest entity for which Indemnity is the primary beneficiary.  All intercompany accounts and transactions have been eliminated in consolidation.  The required presentation of noncontrolling interests is reflected in the consolidated financial statements.  Noncontrolling interests represent the ownership interests of the Exchange, all of which are held by parties other than Indemnity (i.e. the Exchange’s subscribers (policyholders)).  Noncontrolling interests also include the Exchange subscribers’ ownership interest in EFL.
	Presentation of assets and liabilities – While the assets of the Exchange are presented separately in the Consolidated Statements of Financial Position, the Exchange’s assets can only be used to satisfy the Exchange’s liabilities or for other unrestricted activities.  Accounting Standards Codification (“ASC”) 810, Consolidation, does not require separate presentation of the Exchange’s assets; however, because the shareholders of Indemnity have no rights to the assets of the Exchange and, conversely, the Exchange has no rights to the assets of Indemnity, we have presented the invested assets of the Exchange separately on the Consolidated Statements of Financial Position along with the remaining consolidated assets reflecting the Exchange’s portion parenthetically.  Liabilities are required under ASC 810, Consolidation, to be presented separately for the Exchange on the Consolidated Statements of Financial Position as the Exchange’s creditors do not have recourse to the general credit of Indemnity.
	Rights of shareholders of Indemnity and subscribers (policyholders) of the Exchange – The shareholders of Indemnity, through the management fee, have a controlling financial interest in the Exchange; however, they have no other rights to or obligations arising from assets and liabilities of the Exchange.  The shareholders of Indemnity own its equity but have no rights or interest in the Exchange’s (noncontrolling interest) income or equity.  The noncontrolling interest equity represents the Exchange’s equity held for the interest of its subscribers (policyholders), who have no rights or interest in the Indemnity shareholder interest income or equity.
	All intercompany assets, liabilities, revenues, and expenses between Indemnity and the Exchange have been eliminated in the Consolidated Financial Statements.
New accounting pronouncements	'
	Pending accounting pronouncements
	In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects.  This guidance permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met.  Generally, investors in qualified affordable housing project investments expect to receive substantially all of their return through the receipt of tax credits and other tax benefits.  ASU No. 2014-01 allows for the recording of the investment performance net of taxes as a component of income tax expense to more fairly represent the economics of the investments and provide users with a better understanding of the returns from such investments.  The qualifications to make this accounting election were also made less restrictive.  ASU No. 2014-01 is effective for annual and interim periods beginning after December 15, 2014, with early adoption permitted.  While we are currently evaluating whether to make the accounting election and whether the election would be made for early adoption, such election is not expected to have a material impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU No. 2014-09 clarifies the principles for recognizing revenue and provides a common revenue standard for GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Insurance contracts are not within the scope of this guidance. ASU No. 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early application is not permitted. We do not expect the adoption of ASU No. 2014-09 related to the management fee and service agreement revenue to have a material impact on our consolidated financial statements.
Earnings per share	'
	Class A and Class B basic earnings per share and Class B diluted earnings per share are calculated under the two-class method. The two-class method allocates earnings to each class of stock based upon its dividend rights.  Class B shares are convertible into Class A shares at a conversion ratio of 2,400 to 1. See Note 11. “Indemnity Capital Stock”.
	Class A diluted earnings per share are calculated under the if-converted method, which reflects the conversion of Class B shares to Class A shares. Diluted earnings per share calculations include the effect of any potential common shares. Potential common shares include outstanding vested and not yet vested awards related to our outside directors’ stock compensation plan and any employee stock based awards.
Consolidation of variable interest entity	'
	Erie Insurance Exchange
	The Exchange is a reciprocal insurance exchange domiciled in Pennsylvania, for which Indemnity serves as attorney-in-fact.  Indemnity holds a variable interest in the Exchange due to the absence of decision-making capabilities by the equity owners (subscribers/policyholders) of the Exchange and due to the significance of the management fee the Exchange pays to Indemnity as its decision maker.  As a result, Indemnity is deemed to have a controlling financial interest in the Exchange and is considered to be its primary beneficiary.
	Consolidation of the Exchange’s financial results is required given the significance of the management fee to the Exchange and because Indemnity has the power to direct the activities of the Exchange that most significantly impact the Exchange’s economic performance.  The Exchange’s anticipated economic performance is the product of its underwriting results combined with its investment results.  The fees paid to Indemnity under the subscriber’s agreement impact the anticipated economic performance attributable to the Exchange’s results.  Indemnity earns a management fee from the Exchange for the services it provides as attorney-in-fact.  Indemnity’s management fee revenues are based upon all premiums written or assumed by the Exchange.  Indemnity’s Board of Directors determines the management fee rate to be paid by the Exchange to Indemnity.  This rate cannot exceed 25% of the direct and assumed written premiums of the Exchange, as defined by the subscriber’s agreement signed by each policyholder.  Management fee revenues and management fee expenses are eliminated upon consolidation.
	The shareholders of Indemnity have no rights to the assets of the Exchange and no obligations arising from the liabilities of the Exchange.  Indemnity has no obligation related to any underwriting and/or investment losses experienced by the Exchange.  Indemnity would, however, be adversely impacted if the Exchange incurred significant underwriting and/or investment losses.  If the surplus of the Exchange were to decline significantly from its current level, its financial strength ratings could be reduced and, as a consequence, the Exchange could find it more difficult to retain its existing business and attract new business.  A decline in the business of the Exchange would have an adverse effect on the amount of the management fees Indemnity receives.  In addition, a decline in the surplus of the Exchange from its current level may impact the management fee rate received by Indemnity.  Indemnity also has an exposure to a concentration of credit risk related to the unsecured receivables due from the Exchange for its management fee. If any of these events occurred, Indemnity’s financial position, financial performance, and/or cash flows could be adversely impacted.
	All property and casualty and life insurance operations are owned by the Exchange, and Indemnity functions solely as the management company.
	Indemnity has not provided financial or other support to the Exchange for any of the reporting periods presented.  At June 30, 2014, there are no explicit or implicit arrangements that would require Indemnity to provide future financial support to the Exchange.  Indemnity is not liable if the Exchange was to be in violation of its debt covenants or was unable to meet its obligation for unfunded commitments to limited partnerships.
Fair value of financial instruments	'
	Our available-for-sale and trading securities are recorded at fair value, which is the price that would be received to sell the asset in an orderly transaction between willing market participants as of the measurement date.
	Valuation techniques used to derive the fair value of our available-for-sale and trading securities are based upon observable and unobservable inputs.  Observable inputs reflect market data obtained from independent sources.  Unobservable inputs reflect our own assumptions regarding fair market value for these securities.  Although the majority of our prices are obtained from third party sources, we also perform an internal pricing review for securities with low trading volumes under current market conditions. Financial instruments are categorized based upon the following characteristics or inputs to the valuation techniques:
	•	Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
	•	Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
	•	Level 3 – Unobservable inputs for the asset or liability.
	Estimates of fair values for our investment portfolio are obtained primarily from a nationally recognized pricing service.  Our Level 1 category includes those securities valued using an exchange traded price provided by the pricing service.  The methodologies used by the pricing service that support a Level 2 classification of a financial instrument include multiple verifiable, observable inputs including benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data.  Pricing service valuations for Level 3 securities are based upon proprietary models and are used when observable inputs are not available or in illiquid markets.
	In limited circumstances we adjust the price received from the pricing service when, in our judgment, a better reflection of fair value is available based upon corroborating information and our knowledge and monitoring of market conditions such as a disparity in price of comparable securities and/or non-binding broker quotes.  In other circumstances, certain securities are internally priced because prices are not provided by the pricing service.
	We perform continuous reviews of the prices obtained from the pricing service.  This includes evaluating the methodology and inputs used by the pricing service to ensure that we determine the proper classification level of the financial instrument.  Price variances, including large periodic changes, are investigated and corroborated by market data.  We have reviewed the pricing methodologies of our pricing service as well as other observable inputs, such as data, and transaction volumes and believe that their prices adequately consider market activity in determining fair value.  Our review process continues to evolve based upon accounting guidance and requirements.
	When a price from the pricing service is not available, values are determined by obtaining broker/dealer quotes and/or market comparables.  When available, we obtain multiple quotes for the same security.  The ultimate value for these securities is determined based upon our best estimate of fair value using corroborating market information.  Our evaluation includes the consideration of benchmark yields, reported trades, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data.
	For certain securities in an illiquid market, there may be no prices available from a pricing service and no comparable market quotes available.  In these situations, we value the security using an internally-developed, risk-adjusted discounted cash flow model.
Fair value of financial instruments, transfers between levels	'
	We review the fair value hierarchy classifications each reporting period.  Transfers between hierarchy levels may occur due to changes in the available market observable inputs.  Transfers in and out of level classifications are reported as having occurred at the beginning of the quarter in which the transfers occurred.
Investments - Limited partnerships	'
	Limited partnership investments, excluding certain real estate limited partnerships recorded at fair value, are generally reported on a one-quarter lag, therefore our year-to-date limited partnership results through June 30, 2014 are comprised of partnership financial results for the fourth quarter of 2013 and first quarter of 2014.  Given the lag in reporting, our limited partnership results do not reflect the market conditions of the second quarter of 2014.  Cash contributions made to and distributions received from the partnerships are recorded in the period in which the transaction occurs.
Deferred taxes	'
	Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns.  Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.
Commitments and contingencies	'
	We are involved in litigation arising in the ordinary course of conducting business.  In accordance with current accounting standards for loss contingencies and based upon information currently known to us, we establish reserves for litigation when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss or range of loss can be reasonably estimated.  When no amount within the range of loss is a better estimate than any other amount, we accrue the minimum amount of the estimable loss.  To the extent that such litigation against us may have an exposure to a loss in excess of the amount we have accrued, we believe that such excess would not be material to our consolidated financial condition, results of operations, or cash flows.  Legal fees are expensed as incurred.  We believe that our accruals for legal proceedings are appropriate and, individually and in the aggregate, are not expected to be material to our consolidated financial condition, operations, or cash flows.
	We review all litigation on an ongoing basis when making accrual and disclosure decisions.  For certain legal proceedings, we cannot reasonably estimate losses or a range of loss, if any, particularly for proceedings that are in their early stages of development or where the plaintiffs seek indeterminate damages.  Various factors, including, but not limited to, the outcome of potentially lengthy discovery and the resolution of important factual questions, may need to be determined before probability can be established or before a loss or range of loss can be reasonably estimated.  If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable.  In the event that a legal proceeding results in a substantial judgment against, or settlement by, us, there can be no assurance that any resulting liability or financial commitment would not have a material adverse effect on the financial condition, results of operations, or cash flows of the Indemnity shareholder interest or the consolidated financial statements of Erie Indemnity Company.

	(1)          Other investments measured at fair value represent four real estate funds included on the balance sheet as limited partnership investments that are reported under the fair value option. These investments can never be redeemed with the funds. Instead, distributions are received when liquidation of the underlying assets of the funds occur. It is estimated that the underlying assets will generally be liquidated between 5 and 10 years from the inception of the funds. The fair value of these investments is based on the net asset value (NAV) information provided by the general partner. Fair value is based on our proportionate share of the NAV based on the most recent partners' capital statements received from the general partners, which is generally one quarter prior to our balance sheet date. These values are then analyzed to determine if they represent the NAV at our balance sheet date, with adjustment being made where appropriate. We consider observable market data and perform a review validating the appropriateness of the NAV at each balance sheet date. It is likely that all of the investments will be redeemed at a future date for an amount different than the NAV of our ownership interest in partners' capital as of December 31, 2013. During the year ended December 31, 2013, Indemnity made no contributions and received distributions totaling $2.4 million, and the Exchange made no contributions and received distributions totaling $21.7 million for these investments. As of December 31, 2013, the amount of unfunded commitments related to the investments was $1.5 million for Indemnity and $4.5 million for the Exchange.

	-1	Corporate debt securities – The unobservable input used in the fair value measurement of certain corporate debt securities is the likelihood of repayment by the underlying entity when there is no market for trading these securities.  When available, we obtain non-binding broker quotes to value such securities. When a non-binding broker quote was the only input available, it was considered unobservable.
	-2	Collateralized-debt-obligation securities – The unobservable inputs used in the fair value measurement of certain collateralized-debt-obligation securities are the repayment at maturity of underlying collateral available to pay note holders, the projected maturity of the underlying security, and a discount rate appropriate for the security.  Significant changes in any of those inputs in isolation would result in a significantly higher or lower fair value measurement.  Generally, a change in the assumption used for the performance of the underlying collateral is accompanied by an opposite change in the maturity and a directionally opposite change in the discount rate used to value the security.
	-3	Common stock investments and Corporate debt securities – The unobservable inputs used in the fair value measurement of direct private equity common stock investments and certain corporate debt securities are comparable private transaction earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples, the average EBITDA multiple for comparable publicly traded companies and the amount of discount applied to the price due to the illiquidity of the securities being valued.  Significant changes in any of those inputs in isolation could result in a significantly higher or lower fair value measurement.
	-4	Other investments – Other investments represent certain limited partnerships that are recorded at fair value and are based upon net asset value (NAV) provided by the general partner where the unobservable inputs are not reasonably available to us.
	-5	Nonredeemable preferred stock - The unobservable input used in the fair value measurement of a private nonredeemable preferred stock security is the price to sales ratio for comparable publicly traded companies.
	Securities valued using unobservable inputs shown above totaled $162 million at June 30, 2014. In total, Level 3 assets represent less than 1.2% of the total assets measured at fair value on a recurring basis for the Erie Insurance Group.
