Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
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 and primarily writes private passenger auto (44%), homeowners (26%), commercial multi-peril (13%), commercial automobile (7%), and workers compensation (7%) lines of insurance based upon 2013 direct written premiums.
	Erie Family Life Insurance Company (“EFL”) is an affiliated life insurance company that underwrites and sells individual and group life insurance policies and fixed annuities.  On March 31, 2011, Indemnity sold its 21.6% ownership interest in EFL to the Exchange.
	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).

	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 affiliated 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.
	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 is 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.
	Adopted accounting pronouncements
	In October 2010, the FASB issued ASU 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts.  This guidance modified the definition of the types of costs incurred by insurance entities that can be capitalized in the acquisition of new and renewal insurance contracts.  The amendments in this guidance specify that the costs are limited to incremental direct costs that result directly from successful contract transactions and would not have been incurred by the insurance entity had the contract transactions not occurred.  These costs must be directly related to underwriting, policy issuance and processing, medical and inspection reports and sales force contract selling.  The amendments also specify that advertising costs are only included as deferred acquisition costs if the direct-response advertising criteria are met.  ASU 2010-26 was effective for interim and annual reporting periods beginning after December 15, 2011.  We elected to prospectively adopt this guidance.  The change does not affect the Indemnity shareholder interest nor does it affect Indemnity’s earnings per share.  Acquisition costs capitalized during the year ended December 31, 2012 totaled $743 million.  Acquisition costs that would have been capitalized during the year ended December 31, 2012 using the previous method of capitalization totaled $763 million.  Included in this note below is our updated accounting policy under the caption “Deferred acquisition costs”.
	In May 2011, the FASB issued ASU 2011-4, Fair Value Measurements.  This guidance changed the description of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements and certain other changes to converge with the fair value guidance of the International Accounting Standards Board (“IASB”).  The amendments in this guidance detail the requirements specific to measuring the fair value of an instrument classified in a reporting entity’s shareholders’ equity.  The amendments also clarify that a reporting entity should disclose quantitative information about the significant unobservable inputs used in the fair value measurement categorized within Level 3 of the fair value hierarchy.  ASU 2011-4 was effective for interim and annual periods beginning after December 15, 2011.  The adoption of this new guidance did not have a material impact on our consolidated financial statements. The additional disclosures required by this guidance have been included in Note 6, “Fair Value”.
	In June 2011, the FASB issued ASU 2011-5, Comprehensive Income.  This guidance eliminated the option to present components of other comprehensive income as part of the statement of changes in shareholders’ equity.  The amendments in this guidance specify that an entity has the option to present the total comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements.  The disclosures required remain the same.  In both options, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income.  ASU 2011-5 was effective for interim and annual periods beginning after December 15, 2011.  In December 2011, the FASB issued ASU 2011-12, Comprehensive Income – Deferral of The Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update 2011-5.  The amendments in this ASU supersede changes to paragraphs in ASU 2011-5 that pertain to how, when and where reclassification adjustments are presented.  We have elected to present total comprehensive income in two separate but consecutive statements.  The disclosures required by this guidance have been included in the Consolidated Statements of Operations and the Consolidated Statements of Comprehensive Income.
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.  The amendments in this ASU require an entity to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the line items affected by the reclassification. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other related disclosures for additional information. ASU 2013-02 is effective prospectively for interim and annual periods beginning after December 15, 2012.  We have elected to present amounts reclassified out of accumulated other comprehensive income by component and the respective line items of net income in the notes to our consolidated financial statements. See Note 18, "Indemnity Accumulated Other Comprehensive Loss".
	Pending accounting pronouncements
	In February 2013, the FASB issued ASU 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. The amendments in this ASU provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP. ASU 2013-04 is effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted.  We do not expect the adoption of this new guidance to have a material impact on our consolidated financial statements.
	In January 2014, the FASB issued ASU 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 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 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.
	Investments
	Available-for-sale securities – Fixed maturity, preferred stock, and common stock securities classified as available-for-sale are reported at fair value.  Unrealized holding gains and losses, net of related tax effects, on available-for-sale securities are charged or credited directly to shareholders’ equity as accumulated other comprehensive income (loss).
	Common stock securities classified as available-for-sale represent certain exchange traded funds with underlying holdings of fixed maturity securities.
	Realized gains and losses on sales of available-for-sale securities are recognized in income based upon the specific identification method.  Interest and dividend income are recognized as earned.
	Fixed income and redeemable preferred stock (debt securities) are evaluated monthly for other-than-temporary impairment loss.  For debt securities that have experienced a decline in fair value and that we intend to sell, or for which it is more likely than not we will be required to sell the security before recovery of its amortized cost, an other-than-temporary impairment is deemed to have occurred, and is recognized in earnings.
	Debt securities that have experienced a decline in fair value and that we do not intend to sell, and that we will not be required to sell before recovery, are evaluated to determine if the decline in fair value is other-than-temporary.
	Some factors considered in this evaluation include:
	•	the extent and duration to which fair value is less than cost;
	•	historical operating performance and financial condition of the issuer;
	•	short and long-term prospects of the issuer and its industry based upon analysts’ recommendations;
	•	specific events that occurred affecting the issuer, including a ratings downgrade;
	•	near term liquidity position of the issuer; and
	•	compliance with financial covenants.
	If a decline is deemed to be other-than-temporary, an assessment is made to determine the amount of the total impairment related to a credit loss and that related to all other factors.  Consideration is given to all available information relevant to the collectability of the security in this determination. If the entire amortized cost basis of the security will not be recovered, a credit loss exists.  Currently, we have the intent to sell all of our securities that have been determined to have a credit-related impairment.  As a result, the entire amount of any impairment would be recognized in earnings.  If we had securities with credit impairments that we did not intend to sell, the non-credit portion of the impairment would be recorded in other comprehensive income.
	Other-than-temporary impairment charges on non-redeemable preferred securities, hybrid securities with equity characteristics and common stock are included in earnings consistent with the treatment for equity securities.
	Trading securities – Common stock securities classified as trading securities are reported at fair value.  Unrealized holding gains and losses on trading securities are included in net realized gains (losses) in the Consolidated Statements of Operations.  Realized gains and losses on sales of trading securities are recognized in income based upon the specific identification method.  Dividend income is recognized as of the ex-dividend date.
	Limited partnerships – Limited partnerships include U.S. and foreign private equity, mezzanine debt, and real estate investments.  The majority of our limited partnership holdings are considered investment companies and are recorded using the equity method of accounting. For these limited partnerships the general partners record assets at fair value, including any other-than-temporary impairments of these individual investments. We also own some real estate limited partnerships that do not meet the criteria of an investment company. These partnerships prepare their audited financial statements on a cost basis. We have elected to report these limited partnerships under the fair value option, which is based on the net asset value (NAV) from our partner’s capital statement reflecting the general partner’s estimate of fair value for the fund’s underlying assets. Limited partnerships reported under the fair value option are disclosed in Note 6, “Fair Value” as other investments. Fair value provides consistency in the evaluation and financial reporting for these limited partnerships and limited partnerships accounted for under the equity method.
	Because of the timing of the preparation and delivery of financial statements for limited partnership investments, the use of the most recently available financial statements provided by the general partners result in a quarter delay in the inclusion of the limited partnership results in our Consolidated Statements of Operations.  Due to this delay, these financial statements do not yet reflect the market conditions experienced in the fourth quarter of 2013 for all partnerships other than the real estate limited partnerships that are reported under the fair value option.
	Nearly all of the underlying investments in our limited partnerships are valued using a source other than quoted prices in active markets.  The fair value amounts for our private equity and mezzanine debt partnerships are based upon the financial statements of the general partners, who use multiple methods to estimate fair value including the market approach, income approach or the cost approach.  The market approach uses prices and other pertinent information from market-generated transactions involving identical or comparable assets or liabilities.  Such valuation techniques often use market multiples derived from a set of comparables.  The income approach uses valuation techniques to convert future cash flows or earnings to a single discounted present value amount.  The measurement is based upon the value indicated by current market expectations on those future amounts.  The cost approach is derived from the amount that is currently required to replace the service capacity of an asset.  If information becomes available that would impair the cost of investments owned by the partnerships, then the general partner would adjust to the net realizable value.  For real estate limited partnerships, the general partners record these at fair value based upon an independent appraisal or internal estimates of fair value.
	We perform various procedures in review of the general partners’ valuations.  While we generally rely on the general partners’ financial statements as the best available information to record our share of the partnership unrealized gains and losses resulting from valuation changes, we adjust our financial statements for impairments at the fund level as necessary.  As there is a limited market for these investments, they have the greatest potential for market price variability.
	Unrealized gains and losses for these investments are reflected in equity in earnings (losses) of limited partnerships in our Consolidated Statements of Operations in accordance with the equity method of accounting or the fair value option, as applicable.  Cash contributions made to and distributions received from the partnerships are recorded in the period in which the transaction occurs.
	Cash and cash equivalents – Short-term investments, consisting of cash, money market accounts and other short-term, highly liquid investments with a maturity of three months or less at the date of purchase, are considered cash and cash equivalents.
	Deferred acquisition costs
	Acquisition costs that vary with and relate to the successful production of insurance and investment-type contracts are deferred.  Beginning in 2012, deferred acquisition costs (“DAC”) are incremental direct costs of contract acquisition and are limited to the successful acquisition of new and renewal contracts.  Such costs consist principally of commissions, premium taxes and policy issuance expenses. Prior to 2012, certain of these acquisition costs were deferred regardless of whether a contract was acquired.
	Property and casualty insurance – DAC related to property and casualty insurance contracts are primarily composed of commissions, premium taxes, and certain underwriting expenses. These costs are amortized on a pro-rata basis over the applicable policy term.  We consider investment income in determining if a premium deficiency exists, and if so, it would first be recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency.  If the premium deficiency would be greater than unamortized acquisition costs, a liability would be accrued for the excess deficiency. There was no reduction in costs deferred in any periods presented.  Profitability is analyzed annually to ensure recoverability.
	Life insurance – DAC related to traditional life insurance products is amortized in proportion to premium revenues over the premium-paying period of related policies using assumptions about mortality, morbidity, lapse rates, expenses, and future yield on related investments established when the policy was issued.  Amortization is adjusted each period to reflect policy lapse or termination rates as compared to anticipated experience.  DAC related to universal life products and deferred annuities is amortized over the estimated lives of the contracts in proportion to actual and expected future gross profits, investment, mortality, expense margins, and surrender charges.  Both historical and anticipated investment returns, including realized gains and losses, are considered in determining the amortization of DAC.
	Estimated gross profits are adjusted monthly to reflect actual experience to date and/or for the unlocking of underlying key assumptions based upon experience studies.  DAC is periodically reviewed for recoverability.  For traditional life products, if the benefit reserves plus anticipated future premiums and interest earnings for a line of business are less than the current estimate of future benefits and expenses (including any unamortized DAC), a charge to income is recorded for additional DAC amortization or for increased benefit reserves.  For universal life and deferred annuities, if the current present value of future expected gross profits is less than the unamortized DAC, a charge to income is recorded for additional DAC amortization.
	Deferred taxes
	Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, using the statutory tax rates in effect for the year in which the differences are expected to reverse.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date under the law.  Valuation allowances on deferred tax assets are estimated based upon our assessment of the realizability of such amounts.
	Property and casualty unpaid losses and loss expenses
	Unpaid losses and loss expenses include estimates for claims that have been reported and those that have been incurred but not reported, as well as estimates of all expenses associated with processing and settling these claims, less estimates of anticipated salvage and subrogation recoveries.  Unpaid loss and loss expense reserves are set at full expected cost, except for workers compensation loss reserves, which have been discounted using an interest rate of 2.5%.  Estimating the ultimate cost of future losses and loss expenses is an uncertain and complex process.  This estimation process is based upon the assumption that past developments are an appropriate indicator of future events, and involves a variety of actuarial techniques that analyze experience, trends, and other relevant factors.  The uncertainties involved with the reserving process include internal factors, such as changes in claims handling procedures, as well as external factors, such as economic trends and changes in the concepts of legal liability and damage awards.  Accordingly, final loss settlements may vary from the present estimates, particularly when those payments may not occur until well into the future.
	We regularly review the adequacy of our estimated loss and loss expense reserves by line of business.  Adjustments to previously established reserves are reflected in the operating results of the period in which the adjustment is determined to be necessary.  Such adjustments could possibly be significant, reflecting any variety of new and adverse or favorable trends.
	Life insurance reserves
	The liability for future benefits of life insurance contracts is the present value of such benefits less the present value of future net premiums.  Life insurance and income-paying annuity future policy benefit reserves are computed primarily by the net level premium method with assumptions as to mortality, withdrawal, lapses, and investment yields.  Traditional life insurance products are subject to loss recognition testing.  The adequacy of the related reserves is verified as part of loss recognition testing.  Loss recognition is necessary when the sum of the reserve and the present value of projected policy cash flows is less than unamortized DAC.
	Deferred annuity future benefit reserves are established at accumulated account values without reduction for surrender charges.  These account values are credited with varying interest rates determined at the discretion of EFL subject to certain minimums.
	Agent bonus estimates
	Agent bonuses are based upon an individual agency’s property and casualty underwriting profitability and also include a component for growth in agency property and casualty premiums if the agency’s underwriting profitability targets for our book of business are met.  The estimate for agent bonuses, which are based upon the performance over 36 months, is modeled on a monthly basis using actual underwriting data by agency for the prior 2 years combined with the current year-to-date actual data.
	At December 31 of each year, we use actual data available and record an accrual based upon the expected payment amount.  These costs are included in the policy acquisition and underwriting expenses in the Consolidated Statements of Operations.
	Recognition of premium revenues and losses
	Property and casualty insurance – Insurance premiums written are earned over the terms of the policies on a pro-rata basis. Premiums receivable from policyholders represent premiums written but not yet collected. Premiums receivable are reported net of an allowance for uncollectible premiums.  Unearned premiums represent that portion of premiums written which is applicable to the unexpired terms of policies in force.  Losses and loss expenses are recorded as incurred.
	Life insurance – Premiums on traditional life insurance products are recognized as revenue when due.  Reserves for future policy benefits are established when premiums are earned.  Premiums received for annuity and universal life products are reported as deposits and included in liabilities.  For universal life products, revenue is recognized when amounts are assessed against the policyholder’s account for mortality coverage and contract expenses.  The primary source of revenue on annuity deposits is derived from the interest earned by EFL, which is reflected in net investment income.
	Reinsurance
	Property and casualty insurance – Property and casualty assumed and ceded reinsurance premiums are earned over the terms of the reinsurance contracts.  Premiums ceded to other companies are reported as a reduction of premium income.  Reinsurance contracts do not relieve the Property and Casualty Group from its obligations to policyholders.
	Life insurance – Reinsurance premiums, commissions, and expense reimbursements on reinsurance ceded on life insurance policies are accounted for on a basis consistent with those used in accounting for the underlying reinsured policies.  Expense reimbursements received in connection with new reinsurance ceded have been accounted for as a reduction of the related policy acquisition costs.  Amounts recoverable from reinsurers for future policy benefits are estimated in a manner consistent with the assumptions used for the underlying policy benefits.  Amounts recoverable for incurred claims, future policy benefits, and expense reimbursements are recorded as assets.  Reinsurance contracts do not relieve EFL from its obligations to policyholders.
	Recognition of management fee revenue
Indemnity earns management fees from the Exchange for providing sales, underwriting, and policy issuance services.  Pursuant to the subscriber’s agreements with the policyholders at the Exchange, Indemnity may retain up to 25% of all premiums written or assumed by the Exchange.  Management fee revenue is calculated by multiplying the management fee rate by 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 as revenue upon policy issuance or renewal, as substantially all of the services required to be performed by us 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.  Management fee revenue is eliminated upon consolidation.
Recognition of service agreement revenue
Included in service agreement revenue are service charges Indemnity collects from policyholders for providing multiple payment plans on policies written by the Property and Casualty Group.  Service charges, which are flat dollar charges for each installment billed beyond the first installment, are recognized as revenue when bills are rendered to the policyholder.  Service agreement revenue also includes late payment and policy reinstatement fees.  Service agreement revenue is included in other income in the Consolidated Statements of Operations.

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 17, “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.
	On March 31, 2011, Indemnity sold its 21.6% ownership interest in EFL to the Exchange.  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 December 31, 2013, 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_Information

Segment Information	12 Months Ended
	Dec. 31, 2013
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 Note 2, “Significant Accounting Policies”).  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.
	Additionally, the year ended December 31, 2012 includes an adjustment that reduced commission expense by $6 million.  This amount represents the reimbursement by the North Carolina Reinsurance Facility (NCRF) for commissions Indemnity paid to agents on the surcharges collected on behalf of the NCRF which was incorrectly recorded as a benefit to the Exchange in prior periods.  If these amounts had been correctly recorded, Indemnity’s commission expense would have been lower by $0.5 million for the year ended December 31, 2011.
	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.  In 2013, investment activities on life insurance-related assets generated revenues of $111 million, resulting in EFL reporting income before income taxes of $48 million, before intercompany eliminations.  In 2012, investment activities on life insurance-related assets generated revenues of $104 million, resulting in EFL reporting income before income taxes of $46 million, before intercompany eliminations.  In 2011, investment activities on life insurance-related assets generated revenues of $109 million, resulting in EFL reporting income before income taxes of $50 million, 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 in the 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 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 Statements of Operations. There was $2 million included in net realized investment gains (losses) and $2 million included in equity in earnings of limited partnerships for the three months ended December 31, 2013 on Level 3 investments.
(2)          Transfers in and out of Level 3 are attributable to changes in the availability of market observable information for individual investments 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 both Indemnity and the Exchange, there were no transfers between Level 1 and Level 2, or Level 2 and Level 3, for the three months ended December 31, 2013.

(1)          These amounts are reported in the Consolidated Statements of Operations. There was $6 million included in net realized investment gains (losses) and $12 million included in equity in earnings of limited partnerships for the year ended December 31, 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 investments 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 year ended December 31, 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 Level 2 and Level 3.
For the Exchange, Level 1 to Level 2 transfers totaled $6 million and Level 2 to Level 1 transfers totaled $51 million due to trading activity levels related to one preferred stock holding and five preferred stock holdings, respectively, for the year ended December 31, 2013. Level 2 to Level 3 transfers totaled $39 million for seven fixed maturity holdings and one preferred stock holding, and Level 3 to Level 2 transfers totaled $47 million for six 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 December 31, 2013.

-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.
-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	Corporate debt securities and Collateralized-debt-obligation securities – When a non-binding broker quote was the only input available, it was considered unobservable.
-4	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.
-5	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.
Securities valued using unobservable inputs shown above totaled $164 million at December 31, 2013. In total, Level 3 assets represent less than 1.3% of the assets measured at fair value on a recurring basis for the Erie Insurance Group.

(1)          These amounts are reported in the Consolidated Statements of Operations. There was $1 million included in net realized investment gains (losses) and $3 million included in equity in earnings of limited partnerships for the three months ended December 31, 2012 on Level 3 investments.
(2)          Transfers in and out of Level 3 are attributable to changes in the availability of market observable information for individual investments 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, Level 1 to Level 2 transfers totaled $4 million for the three months ended December 31, 2012. Trading activity levels for two preferred stock holdings necessitated reclassification between levels. There were no transfers from Level 2 to Level 1 or between Level 2 and Level 3.
For the Exchange, Level 1 to Level 2 transfers totaled $69 million, and there were no Level 2 to Level 1 transfers for the three months ended December 31, 2012. Trading activity levels for 10 preferred stock holdings necessitated reclassification between levels. In addition, seven U.S. Treasury securities were reclassified from Level 1 to Level 2. Level 2 to Level 3 transfers totaled $12 million related to one fixed maturity holding, and Level 3 to Level 2 transfers totaled $35 million related to one preferred stock and three fixed maturity holdings. These transfers in and out of Level 3 were primarily the result of using unobservable and observable market data, respectively, to determine the fair value at December 31, 2012.

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.

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.  See also Note 2, “Significant Accounting Policies.”
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 December 31, 2013 are comprised of partnership financial results for the fourth quarter of 2012 and the first, second and third quarters of 2013.  Given the lag in reporting, our limited partnership results do not reflect the market conditions of the fourth quarter of 2013.   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:

Capitalized Software Development Costs	'
	Note 8.  Capitalized Software Development Costs
	We capitalize computer software costs developed or obtained for internal use.  Capitalized costs include internal and external labor and overhead, all of which are attributable to Indemnity.  Capitalization ceases and amortization begins no later than the point at which a computer software project is complete and ready for its intended use.  Capitalized software costs are amortized over the estimated useful life of the software.
	The following table outlines the total capitalized software development costs subject to amortization and the related amortization expense:

Bank Line of Credit	'
	Note 9.  Bank Line of Credit
	On October 25, 2013, Indemnity amended its revolving credit facility to extend the maturity date, lower the borrowing costs, and eliminate the minimum net worth financial covenant. As of December 31, 2013, 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 December 31, 2013, 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 December 31, 2013. Bonds with a fair value of $111 million were pledged as collateral on the line at December 31, 2013.
	On October 25, 2013, the Exchange entered into a second amended and restated credit agreement to extend the maturity date, lower the borrowing costs, and eliminate the minimum statutory surplus covenant. As of December 31, 2013, 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 December 31, 2013, 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 December 31, 2013.  Bonds with a fair value of $332 million were pledged as collateral on the line at December 31, 2013.
	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 December 31, 2013.  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 December 31, 2013.

Indemnity is the attorney-in-fact for the subscribers (policyholders) at the Exchange, a reciprocal insurance exchange.  In that capacity, Indemnity provides all services and facilities necessary to conduct the Exchange’s insurance business.  Indemnity and the Exchange together constitute a single insurance business.  Indemnity is not subject to state corporate income or franchise taxes in states where the Exchange conducts its business and the states collect premium tax in lieu of corporate income or franchise tax, as a result of the Exchange’s remittance of premium taxes in those states.

	Loss reserves are set at full expected cost, except for workers compensation loss reserves, which have been discounted using an interest rate of 2.5% for all periods presented.  This discounting reduced unpaid losses and loss expenses by $85 million, $85 million and $84 million at December 31, 2013, 2012 and 2011, respectively.  The reserves for losses and loss expenses are reported net of receivables for salvage and subrogation, which totaled $149 million, $150 million and $145 million at December 31, 2013, 2012 and 2011, respectively.
	Favorable development on prior accident year loss reserves was minimal in 2013. In 2012, the favorable development on prior accident year direct loss reserves was primarily the result of improved claims frequency and severity trends combined with the closing of several large claims in our homeowners, commercial multi-peril, and commercial auto lines of business, offset somewhat by adverse development in our workers compensation line of business as a result of increased severity trends. In 2011, the favorable development on prior accident year direct loss reserves was primarily the result of improvements in severity trends in our personal auto, workers compensation, commercial multi-peril and homeowners lines of business combined with the closing of several large claims.

Reinsurance Disclosures [Abstract]	'
Reinsurance	'
	Note 14.   Reinsurance
	Members of the Property and Casualty Group participate in an intercompany reinsurance pooling agreement.  Under the pooling agreement, all insurance business of the Property and Casualty Group is pooled in the Exchange.  EIC and ENY share in the underwriting results of the reinsurance pool through retrocession.  Since 1995, the Board of Directors has set the allocation of the pooled underwriting results at 5.0% participation for EIC, 0.5% participation for ENY, and 94.5% participation for the Exchange.  The purpose of the pooling agreement is to spread the risks of the members of the Property and Casualty Group collectively across the different lines of business they underwrite and geographic regions in which each operates.  This agreement may be terminated by any party as of the end of any calendar year by providing not less than 365 days advance written notice.  Intercompany pooling accounts are settled in cash within 30 days after the end of each quarterly accounting period.
	Reinsurance contracts do not relieve the Property and Casualty Group or EFL from their primary obligations to policyholders.  A contingent liability exists with respect to reinsurance recoverables in the event reinsurers are unable to meet their obligations under the reinsurance agreements.
	The Property and Casualty Group maintains several property catastrophe reinsurance treaties with nonaffiliated reinsurers to mitigate future potential catastrophe loss exposures.  During 2013, a first treaty provided coverage of up to 90% of a loss of $550 million in excess of the Property and Casualty Group’s loss retention of $350 million per occurrence, a second treaty provided coverage of up to 70% of a loss of $225 million in excess of $900 million, and a third treaty provided coverage of up to 70% of a loss of $25 million in excess of $1.125 billion.  The property catastrophe reinsurance treaties that became effective for January 1, 2014 included a first property catastrophe reinsurance treaty providing coverage of up to 30% of a loss of $100 million in excess of the Property and Casualty Group’s loss retention of $300 million per occurrence, a second treaty providing coverage of up to 90% of a loss of $500 million in excess of $400 million, a third treaty providing coverage of up to 85% of a loss of $200 million in excess of $900 million, and a fourth treaty providing coverage of up to 100% of a loss of $25 million in excess of $1.1 billion.  There have been no losses subject to these treaties.
	In addition to the property catastrophe treaties, the Property and Casualty Group also cedes certain individual lines of business to unaffiliated reinsurers and cedes certain individual risks on a facultative basis. The Property and Casualty Group maintains several 100% quota share agreements with A.M. Best A++ rated Hartford Steam Boiler Inspection and Insurance Company.  These agreements cede 100% of the covered insurance risk relating to the reinsured portions of the equipment breakdown, employment practices liability, and identity recovery lines of business.  During 2013, the Property and Casualty Group ceded a total of $21 million in premium to Hartford Steam Boiler.  The cessions for 2012 and 2011 were $17 million and $14 million respectively.
	EFL maintains several reinsurance treaties with nonaffiliated life reinsurance companies in order to reduce claims volatility.  EFL had direct life insurance in force totaling $45 billion and $44 billion at December 31, 2013 and 2012, respectively.  Of these amounts, EFL ceded $21 billion and $22 billion of life insurance in force at December 31, 2013 and 2012, respectively. The largest amount of in force life insurance ceded to one reinsurer totaled $10 billion and $11 billion at December 31, 2013 and 2012, respectively.

Compensation and Retirement Disclosure [Abstract]	'
Postretirement Benefits	'
	Note 15.   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 (“SERP”) for certain members of executive and senior management of the Erie Insurance Group.  The pension plans provide benefits to covered individuals satisfying certain age and service requirements.  The defined benefit pension plan and SERP each provide benefits through a final average earnings formula.
	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 56% of the annual benefit expense of these plans, which represents pension benefits for Indemnity employees performing claims and EFL functions. For our funded pension plan, amounts are settled in cash for the portion of pension costs allocated to the Exchange and EFL, respectively.  For our unfunded plans, we pay the obligations when due and amounts are settled in cash between entities when there is a payout.
	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 December 31, 2013, exists in the event EFL does not honor the annuity contracts.

	Actuarial assumptions
	The following table describes the assumptions at December 31 used to measure the year-end benefit obligations and the net periodic benefit costs for the subsequent year:
	(in millions)		Erie Insurance Group
			2013			2012			2011			2010
	Actuarial assumptions:
	Employee pension plan:
	Discount rate		5.11	%		4.19	%		4.99	%		5.69	%
	Expected return on assets		7.5			7.5			8			8
	Compensation increases (1)		4.15			4.15			4.15			4.15
	SERP:
	Discount rate – pre-retirement/post-retirement		5.11/4.61			4.19/3.69			4.99/4.49			5.69/5.19
	Rate of compensation increase		6			6			6			6
	-1	The rate of compensation increase for the employee plan is age-graded.  An equivalent single compensation increase rate of 4.15% in 2013, 2012 and 2011 would produce similar results.
	The two economic assumptions that have the most impact on the postretirement benefit expense are the discount rate and the long-term rate of return on plan assets.  The discount rate assumption used to determine the benefit obligation for 2013 was based upon a yield curve developed from corporate bond yield information.  The same methodology was employed to develop the discount rates used to determine the benefit obligation for 2012 and 2011, respectively.
	The pension plan's expected long-term rate of return represents the average rate of return to be earned on plan assets over the period the benefits included in the benefit obligation are paid.  To determine the expected long-term rate of return assumption, we utilized models based upon rigorous historical analysis and forward-looking views of the financial markets based upon key factors such as historical returns for the asset class' applicable indices, the correlations of the asset classes under various market conditions and consensus views on future real economic growth and inflation.  The expected future return for each asset class is then combined by considering correlations between asset classes and the volatilities of each asset class to produce a reasonable range of asset return results within which our expected long-term rate of return assumption falls.
	Funding policy/funded status
	Our current policy is generally to contribute an amount equal to the greater of the IRS minimum required contribution or the target normal cost for the year plus interest to the date the contribution is made.  A $15 million contribution will be made to the defined benefit pension plan in the first quarter of 2014. The following table sets forth the funded status of the pension plans and the amounts recognized in the Consolidated Statements of Financial Position as of December 31:

Asset allocation
The employee pension plan utilizes a return seeking and a liability asset matching allocation strategy.  It is based upon the understanding that 1) equity investments are expected to outperform debt investments over the long-term, 2) the potential volatility of short-term returns from equities is acceptable in exchange for the larger expected long-term returns, and 3) a portfolio structured across investment styles and markets (both domestic and foreign) reduces volatility.  As a result, the employee pension plan’s investment portfolio utilizes a broadly diversified asset allocation across domestic and foreign equity and debt markets.  The investment portfolio is composed of commingled pools that are dedicated exclusively to the management of employee benefit plan assets.
The target and actual asset allocation for the portfolio is as follows for the years ended December 31:

Incentive and Deferred Compensation Plans	'
	Note 16.   Incentive and Deferred Compensation Plans
	Annual incentive plan
	Our annual incentive plan is a bonus plan that pays cash to our executive and senior vice presidents annually. The cash awards are based on attainment of corporate and individual performance measures, which can include various financial measures. The plan includes a funding qualifier which considers Indemnity’s financial results, based on operating income, before a payout can be made to plan participants. If the funding qualifier is met, plan participants are eligible to receive the incentive based upon specific performance measures. The measures are established at the beginning of each year by the Executive Compensation and Development Committee of our Board of Directors (“ECDC”), with ultimate approval by the full Board of Directors. For 2013 and 2012, the performance measures primarily included the Property and Casualty Group’s direct written premium and statutory combined ratio.
	Long-term incentive plan
	Our long-term incentive plan (“LTIP”) is a performance based incentive plan designed to reward executive and senior vice presidents who can have a significant impact on our long-term performance and to further align the interests of such employees with those of our shareholders. The LTIP permits grants of performance shares or units, to be satisfied with shares of our Class A common stock or cash payment as determined by the ECDC. The ECDC determines the form of the award to be granted at the beginning of each performance period, which is generally a three-year period. The number of shares of the Company’s common stock authorized for grant under the LTIP is 1 million shares, with no one person able to receive more than 250,000 shares or the equivalent of $3 million during any one performance period. We repurchase our Class A common stock on the open market to settle plan awards. We do not issue new shares of common stock to settle plan awards. LTIP awards are considered vested at the end of each applicable performance period.
	The LTIP provides the recipient the right to earn performance shares or units based on the level of achievement of performance goals as defined by us. Performance measures and a peer group of property and casualty companies to be used for comparison are determined by the ECDC. The performance measures for the 2013, 2012 and 2011 awards were the reported combined ratio, growth in direct written premiums and return on invested assets over a three-year performance period as compared to the results of the peer group over the same period. Because the award is based upon a comparison to results of a peer group over a three-year period, the award accrual is based upon estimates of probable results for the remaining performance period. This estimate is subject to variability if our results or the results of the peer group are substantially different than the results we project.
	The fair value of LTIP awards is measured at each reporting date at the current share price of our Class A common stock. A liability is recorded and compensation expense is recognized ratably over the performance period.
	At December 31, 2013, the plan awards for the 2011-2013 performance period were fully vested. Distributions will be made in the form of Class A common stock in 2014 once peer group financial information becomes available. The estimated plan award based upon the peer group information as of September 30, 2013 is $6 million. At December 31, 2012, the awards for the 2010-2012 period were fully vested and the related cash award of $5 million was paid in May 2013. At December 31, 2011, the awards for the 2009-2011 performance period were fully vested and the related cash award of $5 million was paid in June 2012.
	Earned compensation costs are allocated to related entities and reimbursed to Indemnity in cash once the payout is made. The total compensation cost charged to operations related to these LTIP awards was $8 million in 2013, $5 million in 2012, and $9 million in 2011. The related tax benefits recognized in income were $3 million in 2013, $2 million in 2012, and $3 million in 2011.
	At December 31, 2013, there was $9 million of total unrecognized compensation cost for non-vested LTIP awards related to open performance periods. Unrecognized compensation is expected to be recognized over a period of two years.
	Equity compensation plan
	Effective April 17, 2013, our Board of Directors approved an equity compensation plan (“ECP”) designed to reward key employees, as determined by the ECDC or the chief executive officer, who can have a significant impact on our long-term performance and to further align the interests of such employees with those of our shareholders. The ECP permits grants of restricted shares, restricted share units and other share based awards, to be satisfied with shares of our Class A common stock or cash. The ECDC determines the form of the award to be granted at the beginning of each performance period. The number of shares of Indemnity’s Class A common stock authorized for grant under the ECP is 100,000 shares, with no one person able to receive more than 5,000 shares in a calendar year. Share awards are settled through the repurchase of our Class A common stock on the open market. We do not issue new shares of common stock to satisfy plan awards.
	Restricted share awards may be entitled to receive dividends payable during the performance period, or, if subject to performance goals, to receive dividend equivalents payable upon vesting.  Restricted share units may be entitled to receive dividend equivalents, which may provide for the crediting of interest or hypothetical reinvestment experience payable after expiration of the performance period.
	Vesting conditions are determined at the time the award is granted and may include continuation of employment for a specific period, satisfaction of performance goals and the defined performance period, and the satisfaction of any other terms and conditions as determined to be appropriate. The plan is to remain in effect until December 31, 2022, unless earlier amended or terminated by our Board of Directors. There were no awards granted during 2013.
	Deferred compensation plans
	Our deferred compensation plans are arrangements for our executive and senior vice presidents and outside directors that allows participants to elect to defer receipt of a portion of their compensation until a later date. Employer 401(k) matching contributions that are in excess of the annual contribution or compensation limits are also credited to the participant accounts for those who elected to defer receipt of some portion of their base salary. The deferred compensation plan for our outside directors allows participants to defer receipt of a portion of their director and meeting fees until a later date. Employees or outside directors participating in the respective plans select hypothetical investment funds for their deferrals which are credited with the hypothetical returns generated.
	The following summarizes the incentive and deferred compensation plans for the years ended December 31:

	Stock compensation plan for outside directors
	We have a stock compensation plan for our outside directors to further align the interests of directors with those of our shareholders that provides for a portion of the directors’ annual compensation in shares of our Class A common stock.  Each director vests in the grant 25% every three months over the course of a year.  Dividends paid by us are reinvested into each directors’ account as additional share credits which vest immediately. Upon ending board service, directors are paid shares of our Class A common stock equal to the number of share credits in their deferred stock account. Our practice is to repurchase shares of our Class A common stock in the open market to satisfy these awards. We do not issue new shares of common stock to directors. The annual charge related to these awards totaled $1 million, $0.5 million and $1 million in 2013, 2012 and 2011, respectively.

	We have two classes of common stock: Class A which has a dividend preference and Class B which has voting power and a conversion right.  Each share of Class A common stock outstanding at the time of the declaration of any dividend upon shares of Class B common stock shall be entitled to a dividend payable at the same time, at the same record date, and in an amount at least equal to 2/3 of 1.0% of any dividend declared on each share of Class B common stock.  We may declare and pay a dividend in respect to Class A common stock without any requirement that any dividend be declared and paid in respect to Class B common stock.  Sole shareholder voting power is vested in Class B common stock except insofar as any applicable law shall permit Class A common shareholders to vote as a class in regards to any changes in the rights, preferences, and privileges attaching to Class A common stock.  Holders of Class B shares may, at their option, convert their shares into Class A shares at the rate of 2,400 Class A shares per Class B share.  There were no conversions of Class B shares to Class A shares in 2013. In 2012, four shares of Class B common stock were converted into 9,600 shares of Class A common stock.  There were no conversions of Class B shares to Class A shares in 2011.  There is no provision for conversion of Class A shares to Class B shares, and, Class B shares surrendered for conversion cannot be reissued.
	Stock repurchases
	A stock repurchase program was authorized for our outstanding Class A nonvoting common stock beginning January 1, 2004.  Treasury shares are recorded in the Consolidated Statements of Financial Position at total cost based upon trade date.  Shares repurchased under this program, based upon trade date, totaled 431,556 at a total cost of $31.2 million during 2013, and 978,761 shares at a total cost of $69.5 million during 2012.  In October 2011, our Board of Directors approved a continuation of the current stock repurchase program for a total of $150 million, with no time limitation.  We had approximately $37 million of repurchase authority remaining under this program at December 31, 2013, based upon trade date.
	In 2013, we also repurchased 3,477 shares of our outstanding Class A nonvoting common stock outside of our publicly announced share repurchase program at a total cost of $255,454. Of this amount, 444 and 3,033 shares were purchased in January 2013 and June 2013, respectively, for $30,927, or $69.65 per share, and $224,527, or $74.03 per share, respectively, to settle payments due to a retired executive under our long-term incentive plan.  These shares were delivered to the plan participant in January 2013 and July 2013.
	In 2012, we repurchased 1,803 shares of our outstanding Class A nonvoting common stock outside of our publicly announced share repurchase program at a total cost of $129,849. Of this amount, 669 and 1,134 shares were purchased in January 2012 and June 2012, respectively, for $50,724, or $75.82 per share, and $79,125, or $69.78 per share, respectively, to settle payments due to two retired senior vice presidents under our long-term incentive plan. These shares were delivered to the plan participants in January 2012 and June 2012, respectively.

	Note 19.  Commitments and Contingencies
	Indemnity has contractual commitments to invest up to $29 million related to its limited partnership investments at December 31, 2013.  These commitments are split between private equity securities of $14 million, mezzanine debt securities of $9 million, and real estate activities of $6 million.  These commitments will be funded as required by the limited partnership agreements.
	The Exchange, including EFL, has contractual commitments to invest up to $409 million related to its limited partnership investments at December 31, 2013.  These commitments are split between private equity securities of $152 million, mezzanine debt securities of $160 million, and real estate activities of $97 million.  These commitments will be funded as required by the limited 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.

Statutory Accounting Practices Disclosure [Abstract]	'
Statutory Information	'
	Note 21.  Statutory Information
	Accounting principles used to prepare statutory financial statements differ from those used to prepare financial statements under GAAP.  Prescribed statutory accounting practices (“SAP”) include state laws, regulations, and general administration rules, as well as a variety of publications from the National Association of Insurance Commissioners (“NAIC”).  The statutory financial statements of the Exchange and its subsidiaries, EIC, EPC, Flagship, and EFL, are prepared in accordance with accounting practices prescribed and permitted by the Pennsylvania Insurance Department.  ENY prepares its statutory financial statements in accordance with accounting practices prescribed by the New York Insurance Department.
	Financial statements prepared under statutory accounting principles focus on the solvency of the insurer and generally provide a more conservative approach than under GAAP.  Differences between SAP and GAAP include the valuation of investments, deferred policy acquisition cost assets, the actuarial assumptions used in life reserves, deferred tax assets, and unearned subscriber fees.
	Statutory net income and capital and surplus of the Exchange and its subsidiaries as determined in accordance with SAP prescribed or permitted by insurance regulatory authorities are as follows:
		SAP Net Income (Loss)								SAP Capital and Surplus
		Years ended December 31,								At December 31,
	Exchange and its subsidiaries (in millions)	2013		2012			2011			2013		2012
	Property and casualty insurance operations:
	Erie Insurance Exchange	$	479	$	311		$	182		$	6,467	$	5,633
	Erie Insurance Company	17		14			9			294		276
	Erie Insurance Company of New York	1		(1		)	(1		)	22		21
	Erie Insurance Property & Casualty Company	0		0			0			12		11
	Flagship City Insurance Company	0		0			0			12		11
	Life insurance operations:
	Erie Family Life Insurance Company	15		25			34			291		281
	The minimum statutory capital and surplus requirements under Pennsylvania and New York law for the Exchange’s property and casualty insurance subsidiaries amounts to $12 million.  The Exchange’s property and casualty insurance subsidiaries’ total statutory capital and surplus significantly exceed these minimum requirements, totaling $340 million at December 31, 2013.  The risk-based capital levels of all members of the Property and Casualty Group and EFL significantly exceed the minimum requirements.  Cash and securities with a carrying value of $15 million were deposited by the property and casualty and life entities with regulatory authorities under statutory requirements at December 31, 2013.
	As prescribed by the Insurance Department of the Commonwealth of Pennsylvania, the Exchange records unearned subscriber fees (fees to the attorney-in-fact) as deductions from unearned premium reserve and charges current operations on a pro-rata basis over the periods covered by the policies.  The Pennsylvania-domiciled members of the Property and Casualty Group discount workers compensation loss reserves on a non-tabular basis as prescribed by the Insurance Department of the Commonwealth of Pennsylvania.  The Exchange’s NAIC prepared statutory surplus, excluding the impact of the Pennsylvania prescribed practices, would have been $5.9 billion at December 31, 2013.  EIC’s NAIC prepared statutory surplus, excluding the impact of the Pennsylvania prescribed practices, would have been $290 million at December 31, 2013.  EPC and Flagship record the discounting of workers compensation loss reserves on a direct basis, however, after application of the intercompany pooling arrangement, there is no impact on their financial statements.
	The amount of dividends that can be paid to the Exchange without the prior approval by the Pennsylvania Insurance Commissioner by EIC, EPC, and Flagship, the Exchange’s Pennsylvania-domiciled property and casualty insurance subsidiaries, is limited to not more than the greater of: (a) 10% of statutory surplus as reported in the last annual statement, or (b) net income as reported in the last annual statement.  The amount of dividends that EIC’s New York-domiciled property and casualty subsidiary, ENY, can pay without the prior approval by the New York Superintendent of Insurance is limited to the lesser of: (a) 10% of statutory surplus as reported in the last annual statement, or (b) 100% of adjusted net investment income during such period.  In 2014, the maximum dividend payout that the Exchange could receive from its property and casualty insurance subsidiaries would be $33 million.  No dividends were paid by these property and casualty insurance subsidiaries in 2013, 2012 or 2011.
	The amount of dividends that can be paid to the Exchange without the prior approval by the Pennsylvania Insurance Commissioner by EFL, a Pennsylvania-domiciled life insurer, is limited by statute to the greater of: (a) 10% of statutory surplus as shown in the last annual statement on file with the commissioner, or (b) net income as reported in the last annual statement, but shall not include pro-rata distribution of any class of the insurer’s own securities.  Accordingly, the maximum dividend payout that the Exchange could receive in 2014 without prior Pennsylvania Commissioner approval is $29 million.  There were no dividends paid to either the Exchange or Indemnity in 2013, 2012 or 2011.

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 $296 million and $278 million at December 31, 2013 and 2012, respectively.  The receivable from EFL for expense allocations and interest on the surplus note totaled $4 million and $3 million at December 31, 2013 and 2012, respectively.
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.  Indemnity recognized interest income on the note of $2 million in 2013 and 2012.

-1	Earnings on life insurance related invested assets are integral to the evaluation of the life insurance operations because of the long duration of life products.  On that basis, for presentation purposes, the life insurance operations in the table above include life insurance related investment results.  However, the life insurance investment results are included in the investment operations segment discussion in Note 5, “Segment Information”.
-2	Prior to and through March 31, 2011, Indemnity retained a 21.6% ownership interest in EFL, which accrued to the Indemnity shareholder interest, and the Exchange retained a 78.4% ownership interest in EFL, which accrued to the interest of the subscribers (policyholders) of the Exchange, or noncontrolling interest.  Due to the sale of Indemnity’s 21.6% ownership interest in EFL to the Exchange on March 31, 2011, 100.0% of EFL’s life insurance results accrue to the interest of the subscribers (policyholders) of the Exchange, or noncontrolling interest, after March 31, 2011.
Expense allocations – All claims handling services for the Exchange are performed by Indemnity employees who are entirely dedicated to claims related activities.  All costs associated with these employees are reimbursed to Indemnity from the Exchange’s revenues in accordance with the subscriber’s agreement.  Indemnity is reimbursed by EFL from its revenues for all costs associated with employees who perform life insurance related operating activities for EFL in accordance with its service agreement with Indemnity.  Common overhead expenses included in the expenses paid by Indemnity are allocated based upon appropriate utilization statistics (employee count, square footage, vehicle count, project hours, etc.) specifically measured to accomplish proportional allocations.  Executive compensation is allocated based upon each executive’s primary responsibilities (management services, property and casualty claims operations, EFL operations, and investment operations).  We believe the methods used to allocate common overhead expenses among the affiliated entities are reasonable.
Cash settlements for payments on the account of the Exchange totaled $351 million, $343 million and $325 million in 2013, 2012 and 2011, respectively, and $32 million, $30 million and $28 million in 2013, 2012 and 2011, respectively, for EFL.  These reimbursements are settled on a monthly basis.
Office leases – Indemnity leases certain office space from the Exchange, including the home office and three field office facilities.  Rent expenses under these leases totaled $6 million in 2013, 2012 and 2011.  Indemnity also has a lease commitment with EFL for a branch office until 2018.  Annual rentals paid to EFL under this lease totaled $0.4 million in 2013, 2012 and 2011.

Significant Accounting Policies (Policies)	12 Months Ended

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 affiliated 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.
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 is 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.
Adopted accounting pronouncements	'
	Adopted accounting pronouncements
	In October 2010, the FASB issued ASU 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts.  This guidance modified the definition of the types of costs incurred by insurance entities that can be capitalized in the acquisition of new and renewal insurance contracts.  The amendments in this guidance specify that the costs are limited to incremental direct costs that result directly from successful contract transactions and would not have been incurred by the insurance entity had the contract transactions not occurred.  These costs must be directly related to underwriting, policy issuance and processing, medical and inspection reports and sales force contract selling.  The amendments also specify that advertising costs are only included as deferred acquisition costs if the direct-response advertising criteria are met.  ASU 2010-26 was effective for interim and annual reporting periods beginning after December 15, 2011.  We elected to prospectively adopt this guidance.  The change does not affect the Indemnity shareholder interest nor does it affect Indemnity’s earnings per share.  Acquisition costs capitalized during the year ended December 31, 2012 totaled $743 million.  Acquisition costs that would have been capitalized during the year ended December 31, 2012 using the previous method of capitalization totaled $763 million.  Included in this note below is our updated accounting policy under the caption “Deferred acquisition costs”.
	In May 2011, the FASB issued ASU 2011-4, Fair Value Measurements.  This guidance changed the description of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements and certain other changes to converge with the fair value guidance of the International Accounting Standards Board (“IASB”).  The amendments in this guidance detail the requirements specific to measuring the fair value of an instrument classified in a reporting entity’s shareholders’ equity.  The amendments also clarify that a reporting entity should disclose quantitative information about the significant unobservable inputs used in the fair value measurement categorized within Level 3 of the fair value hierarchy.  ASU 2011-4 was effective for interim and annual periods beginning after December 15, 2011.  The adoption of this new guidance did not have a material impact on our consolidated financial statements. The additional disclosures required by this guidance have been included in Note 6, “Fair Value”.
	In June 2011, the FASB issued ASU 2011-5, Comprehensive Income.  This guidance eliminated the option to present components of other comprehensive income as part of the statement of changes in shareholders’ equity.  The amendments in this guidance specify that an entity has the option to present the total comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements.  The disclosures required remain the same.  In both options, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income.  ASU 2011-5 was effective for interim and annual periods beginning after December 15, 2011.  In December 2011, the FASB issued ASU 2011-12, Comprehensive Income – Deferral of The Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update 2011-5.  The amendments in this ASU supersede changes to paragraphs in ASU 2011-5 that pertain to how, when and where reclassification adjustments are presented.  We have elected to present total comprehensive income in two separate but consecutive statements.  The disclosures required by this guidance have been included in the Consolidated Statements of Operations and the Consolidated Statements of Comprehensive Income.
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.  The amendments in this ASU require an entity to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the line items affected by the reclassification. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other related disclosures for additional information. ASU 2013-02 is effective prospectively for interim and annual periods beginning after December 15, 2012.  We have elected to present amounts reclassified out of accumulated other comprehensive income by component and the respective line items of net income in the notes to our consolidated financial statements. See Note 18, "Indemnity Accumulated Other Comprehensive Loss".
	Pending accounting pronouncements
	In February 2013, the FASB issued ASU 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. The amendments in this ASU provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP. ASU 2013-04 is effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted.  We do not expect the adoption of this new guidance to have a material impact on our consolidated financial statements.
	In January 2014, the FASB issued ASU 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 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 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.
Investments - Available-for-sale securities	'
	Available-for-sale securities – Fixed maturity, preferred stock, and common stock securities classified as available-for-sale are reported at fair value.  Unrealized holding gains and losses, net of related tax effects, on available-for-sale securities are charged or credited directly to shareholders’ equity as accumulated other comprehensive income (loss).
	Common stock securities classified as available-for-sale represent certain exchange traded funds with underlying holdings of fixed maturity securities.
	Realized gains and losses on sales of available-for-sale securities are recognized in income based upon the specific identification method.  Interest and dividend income are recognized as earned.
	Fixed income and redeemable preferred stock (debt securities) are evaluated monthly for other-than-temporary impairment loss.  For debt securities that have experienced a decline in fair value and that we intend to sell, or for which it is more likely than not we will be required to sell the security before recovery of its amortized cost, an other-than-temporary impairment is deemed to have occurred, and is recognized in earnings.
	Debt securities that have experienced a decline in fair value and that we do not intend to sell, and that we will not be required to sell before recovery, are evaluated to determine if the decline in fair value is other-than-temporary.
	Some factors considered in this evaluation include:
	•	the extent and duration to which fair value is less than cost;
	•	historical operating performance and financial condition of the issuer;
	•	short and long-term prospects of the issuer and its industry based upon analysts’ recommendations;
	•	specific events that occurred affecting the issuer, including a ratings downgrade;
	•	near term liquidity position of the issuer; and
	•	compliance with financial covenants.
	If a decline is deemed to be other-than-temporary, an assessment is made to determine the amount of the total impairment related to a credit loss and that related to all other factors.  Consideration is given to all available information relevant to the collectability of the security in this determination. If the entire amortized cost basis of the security will not be recovered, a credit loss exists.  Currently, we have the intent to sell all of our securities that have been determined to have a credit-related impairment.  As a result, the entire amount of any impairment would be recognized in earnings.  If we had securities with credit impairments that we did not intend to sell, the non-credit portion of the impairment would be recorded in other comprehensive income.
	Other-than-temporary impairment charges on non-redeemable preferred securities, hybrid securities with equity characteristics and common stock are included in earnings consistent with the treatment for equity securities.
Investments - Trading securities	'
	Trading securities – Common stock securities classified as trading securities are reported at fair value.  Unrealized holding gains and losses on trading securities are included in net realized gains (losses) in the Consolidated Statements of Operations.  Realized gains and losses on sales of trading securities are recognized in income based upon the specific identification method.  Dividend income is recognized as of the ex-dividend date.
Investments - Limited partnerships	'
	Limited partnerships – Limited partnerships include U.S. and foreign private equity, mezzanine debt, and real estate investments.  The majority of our limited partnership holdings are considered investment companies and are recorded using the equity method of accounting. For these limited partnerships the general partners record assets at fair value, including any other-than-temporary impairments of these individual investments. We also own some real estate limited partnerships that do not meet the criteria of an investment company. These partnerships prepare their audited financial statements on a cost basis. We have elected to report these limited partnerships under the fair value option, which is based on the net asset value (NAV) from our partner’s capital statement reflecting the general partner’s estimate of fair value for the fund’s underlying assets. Limited partnerships reported under the fair value option are disclosed in Note 6, “Fair Value” as other investments. Fair value provides consistency in the evaluation and financial reporting for these limited partnerships and limited partnerships accounted for under the equity method.
	Because of the timing of the preparation and delivery of financial statements for limited partnership investments, the use of the most recently available financial statements provided by the general partners result in a quarter delay in the inclusion of the limited partnership results in our Consolidated Statements of Operations.  Due to this delay, these financial statements do not yet reflect the market conditions experienced in the fourth quarter of 2013 for all partnerships other than the real estate limited partnerships that are reported under the fair value option.
	Nearly all of the underlying investments in our limited partnerships are valued using a source other than quoted prices in active markets.  The fair value amounts for our private equity and mezzanine debt partnerships are based upon the financial statements of the general partners, who use multiple methods to estimate fair value including the market approach, income approach or the cost approach.  The market approach uses prices and other pertinent information from market-generated transactions involving identical or comparable assets or liabilities.  Such valuation techniques often use market multiples derived from a set of comparables.  The income approach uses valuation techniques to convert future cash flows or earnings to a single discounted present value amount.  The measurement is based upon the value indicated by current market expectations on those future amounts.  The cost approach is derived from the amount that is currently required to replace the service capacity of an asset.  If information becomes available that would impair the cost of investments owned by the partnerships, then the general partner would adjust to the net realizable value.  For real estate limited partnerships, the general partners record these at fair value based upon an independent appraisal or internal estimates of fair value.
	We perform various procedures in review of the general partners’ valuations.  While we generally rely on the general partners’ financial statements as the best available information to record our share of the partnership unrealized gains and losses resulting from valuation changes, we adjust our financial statements for impairments at the fund level as necessary.  As there is a limited market for these investments, they have the greatest potential for market price variability.
	Unrealized gains and losses for these investments are reflected in equity in earnings (losses) of limited partnerships in our Consolidated Statements of Operations in accordance with the equity method of accounting or the fair value option, as applicable.  Cash contributions made to and distributions received from the partnerships are recorded in the period in which the transaction occurs.
Investments - Cash and cash equivalents	'
	Cash and cash equivalents – Short-term investments, consisting of cash, money market accounts and other short-term, highly liquid investments with a maturity of three months or less at the date of purchase, are considered cash and cash equivalents.
Deferred acquisition costs	'
	Deferred acquisition costs
	Acquisition costs that vary with and relate to the successful production of insurance and investment-type contracts are deferred.  Beginning in 2012, deferred acquisition costs (“DAC”) are incremental direct costs of contract acquisition and are limited to the successful acquisition of new and renewal contracts.  Such costs consist principally of commissions, premium taxes and policy issuance expenses. Prior to 2012, certain of these acquisition costs were deferred regardless of whether a contract was acquired.
	Property and casualty insurance – DAC related to property and casualty insurance contracts are primarily composed of commissions, premium taxes, and certain underwriting expenses. These costs are amortized on a pro-rata basis over the applicable policy term.  We consider investment income in determining if a premium deficiency exists, and if so, it would first be recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency.  If the premium deficiency would be greater than unamortized acquisition costs, a liability would be accrued for the excess deficiency. There was no reduction in costs deferred in any periods presented.  Profitability is analyzed annually to ensure recoverability.
	Life insurance – DAC related to traditional life insurance products is amortized in proportion to premium revenues over the premium-paying period of related policies using assumptions about mortality, morbidity, lapse rates, expenses, and future yield on related investments established when the policy was issued.  Amortization is adjusted each period to reflect policy lapse or termination rates as compared to anticipated experience.  DAC related to universal life products and deferred annuities is amortized over the estimated lives of the contracts in proportion to actual and expected future gross profits, investment, mortality, expense margins, and surrender charges.  Both historical and anticipated investment returns, including realized gains and losses, are considered in determining the amortization of DAC.
	Estimated gross profits are adjusted monthly to reflect actual experience to date and/or for the unlocking of underlying key assumptions based upon experience studies.  DAC is periodically reviewed for recoverability.  For traditional life products, if the benefit reserves plus anticipated future premiums and interest earnings for a line of business are less than the current estimate of future benefits and expenses (including any unamortized DAC), a charge to income is recorded for additional DAC amortization or for increased benefit reserves.  For universal life and deferred annuities, if the current present value of future expected gross profits is less than the unamortized DAC, a charge to income is recorded for additional DAC amortization.
Deferred taxes	'
	Deferred taxes
	Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, using the statutory tax rates in effect for the year in which the differences are expected to reverse.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date under the law.  Valuation allowances on deferred tax assets are estimated based upon our assessment of the realizability of such amounts.
Property and casualty unpaid losses and loss expenses	'
	Property and casualty unpaid losses and loss expenses
	Unpaid losses and loss expenses include estimates for claims that have been reported and those that have been incurred but not reported, as well as estimates of all expenses associated with processing and settling these claims, less estimates of anticipated salvage and subrogation recoveries.  Unpaid loss and loss expense reserves are set at full expected cost, except for workers compensation loss reserves, which have been discounted using an interest rate of 2.5%.  Estimating the ultimate cost of future losses and loss expenses is an uncertain and complex process.  This estimation process is based upon the assumption that past developments are an appropriate indicator of future events, and involves a variety of actuarial techniques that analyze experience, trends, and other relevant factors.  The uncertainties involved with the reserving process include internal factors, such as changes in claims handling procedures, as well as external factors, such as economic trends and changes in the concepts of legal liability and damage awards.  Accordingly, final loss settlements may vary from the present estimates, particularly when those payments may not occur until well into the future.
	We regularly review the adequacy of our estimated loss and loss expense reserves by line of business.  Adjustments to previously established reserves are reflected in the operating results of the period in which the adjustment is determined to be necessary.  Such adjustments could possibly be significant, reflecting any variety of new and adverse or favorable trends.
Life insurance reserves	'
	Life insurance reserves
	The liability for future benefits of life insurance contracts is the present value of such benefits less the present value of future net premiums.  Life insurance and income-paying annuity future policy benefit reserves are computed primarily by the net level premium method with assumptions as to mortality, withdrawal, lapses, and investment yields.  Traditional life insurance products are subject to loss recognition testing.  The adequacy of the related reserves is verified as part of loss recognition testing.  Loss recognition is necessary when the sum of the reserve and the present value of projected policy cash flows is less than unamortized DAC.
	Deferred annuity future benefit reserves are established at accumulated account values without reduction for surrender charges.  These account values are credited with varying interest rates determined at the discretion of EFL subject to certain minimums.
Agent bonus estimates	'
	Agent bonus estimates
	Agent bonuses are based upon an individual agency’s property and casualty underwriting profitability and also include a component for growth in agency property and casualty premiums if the agency’s underwriting profitability targets for our book of business are met.  The estimate for agent bonuses, which are based upon the performance over 36 months, is modeled on a monthly basis using actual underwriting data by agency for the prior 2 years combined with the current year-to-date actual data.
	At December 31 of each year, we use actual data available and record an accrual based upon the expected payment amount.  These costs are included in the policy acquisition and underwriting expenses in the Consolidated Statements of Operations.
Recognition of premium revenues and losses	'
	Recognition of premium revenues and losses
	Property and casualty insurance – Insurance premiums written are earned over the terms of the policies on a pro-rata basis. Premiums receivable from policyholders represent premiums written but not yet collected. Premiums receivable are reported net of an allowance for uncollectible premiums.  Unearned premiums represent that portion of premiums written which is applicable to the unexpired terms of policies in force.  Losses and loss expenses are recorded as incurred.
	Life insurance – Premiums on traditional life insurance products are recognized as revenue when due.  Reserves for future policy benefits are established when premiums are earned.  Premiums received for annuity and universal life products are reported as deposits and included in liabilities.  For universal life products, revenue is recognized when amounts are assessed against the policyholder’s account for mortality coverage and contract expenses.  The primary source of revenue on annuity deposits is derived from the interest earned by EFL, which is reflected in net investment income.
Reinsurance	'
	Reinsurance
	Property and casualty insurance – Property and casualty assumed and ceded reinsurance premiums are earned over the terms of the reinsurance contracts.  Premiums ceded to other companies are reported as a reduction of premium income.  Reinsurance contracts do not relieve the Property and Casualty Group from its obligations to policyholders.
	Life insurance – Reinsurance premiums, commissions, and expense reimbursements on reinsurance ceded on life insurance policies are accounted for on a basis consistent with those used in accounting for the underlying reinsured policies.  Expense reimbursements received in connection with new reinsurance ceded have been accounted for as a reduction of the related policy acquisition costs.  Amounts recoverable from reinsurers for future policy benefits are estimated in a manner consistent with the assumptions used for the underlying policy benefits.  Amounts recoverable for incurred claims, future policy benefits, and expense reimbursements are recorded as assets.  Reinsurance contracts do not relieve EFL from its obligations to policyholders.
Recognition of management fee revenue	'
	Recognition of management fee revenue
	Indemnity earns management fees from the Exchange for providing sales, underwriting, and policy issuance services.  Pursuant to the subscriber’s agreements with the policyholders at the Exchange, Indemnity may retain up to 25% of all premiums written or assumed by the Exchange.  Management fee revenue is calculated by multiplying the management fee rate by 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 as revenue upon policy issuance or renewal, as substantially all of the services required to be performed by us 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.  Management fee revenue is eliminated upon consolidation.
Recognition of service agreement revenue	'
	Recognition of service agreement revenue
	Included in service agreement revenue are service charges Indemnity collects from policyholders for providing multiple payment plans on policies written by the Property and Casualty Group.  Service charges, which are flat dollar charges for each installment billed beyond the first installment, are recognized as revenue when bills are rendered to the policyholder.  Service agreement revenue also includes late payment and policy reinstatement fees.  Service agreement revenue is included in other income in the Consolidated Statements of Operations.
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 17, “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.
	On March 31, 2011, Indemnity sold its 21.6% ownership interest in EFL to the Exchange.  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 December 31, 2013, 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 in the 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.
Capitalized software development costs for internal use	'
	We capitalize computer software costs developed or obtained for internal use.  Capitalized costs include internal and external labor and overhead, all of which are attributable to Indemnity.  Capitalization ceases and amortization begins no later than the point at which a computer software project is complete and ready for its intended use.  Capitalized software costs are amortized over the estimated useful life of the software.
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.
	-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	Corporate debt securities and Collateralized-debt-obligation securities – When a non-binding broker quote was the only input available, it was considered unobservable.
	-4	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.
	-5	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.
