Summary of Significant Accounting Policies [Abstract]	'
Accounting Policies and Basis of Presentation	'
	Accounting Policies and Basis of Presentation:
	The accompanying consolidated financial statements have been prepared in conformity with the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") of accounting principles generally accepted in the United States of America ("GAAP"). These interim financial statements should be read in conjunction with these notes and those included in the Company's 2012 Annual Report on Form 10-K incorporated herein by reference.
	Pertinent accounting and disclosure pronouncements issued from time to time by the FASB are adopted by the Company as they become effective. Effective January 1, 2012, the Company adopted a prospective application of new GAAP authoritative guidance related to the deferral of costs for acquiring or renewing insurance contracts. The adoption of the guidance resulted in pretax charges of approximately $9 and $31 for the third quarter and first nine months of 2012, respectively. In addition, the FASB issued guidance requiring additional disclosures regarding amounts reclassified out of accumulated other comprehensive income. These matters are addressed in the pertinent financial statements and notes herein.
	The financial accounting and reporting process relies on estimates and on the exercise of judgment. In the opinion of management all adjustments consisting only of normal recurring accruals necessary for a fair presentation of the results have been recorded for the interim periods. Amounts shown in the consolidated financial statements and applicable notes are stated (except as otherwise indicated and as to share data) in millions, which amounts may not add to totals shown due to truncation. Necessary reclassifications are made in prior periods' financial statements whenever appropriate to conform to the most current presentation.

Earnings Per Share [Abstract]	'
Common Share Data	'
	Common Share Data:
	Earnings Per Share - Consolidated basic earnings per share excludes the dilutive effect of common stock equivalents and is computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares actually outstanding for the quarterly and year-to-date periods. Diluted earnings per share are similarly calculated with the inclusion of dilutive common stock equivalents. The following table provides a reconciliation of net income (loss) and the number of shares used in basic and diluted earnings per share calculations.

Investments	'
	Investments:
	The Company may classify its invested assets in terms of those assets relative to which it either (1) has the positive intent and ability to hold until maturity, (2) has available for sale or (3) has the intention of trading. As of September 30, 2013 and December 31, 2012, substantially all the Company's invested assets were classified as "available for sale."
	Fixed maturity securities classified as "available for sale" and other preferred and common stocks (equity securities) are included at fair value with changes in such values, net of deferred income taxes, reflected directly in shareholders' equity. Fair values for fixed maturity securities and equity securities are based on quoted market prices or estimates using values obtained from independent pricing services as applicable.
	The Company reviews the status and fair value changes of each of its investments on at least a quarterly basis during the year, and estimates of other-than-temporary impairments ("OTTI") in the portfolio's value are evaluated and established at each quarterly balance sheet date. In reviewing investments for OTTI, the Company, in addition to a security's market price history, considers the totality of such factors as the issuer's operating results, financial condition and liquidity, its ability to access capital markets, credit rating trends, most current audit opinion, industry and securities markets conditions, and analyst expectations to reach its conclusions. Sudden fair value declines caused by such adverse developments as newly emerged or imminent bankruptcy filings, issuer default on significant obligations, or reports of financial accounting developments that bring into question the validity of previously reported earnings or financial condition, are recognized as realized losses as soon as credible publicly available information emerges to confirm such developments. Absent issuer-specific circumstances that would result in a contrary conclusion, any equity security with an unrealized investment loss amounting to a 20% or greater decline for a six month period is considered OTTI. In the event the Company's estimate of OTTI is insufficient at any point in time, future periods' net income (loss) would be adversely affected by the recognition of additional realized or impairment losses, but its financial position would not necessarily be affected adversely inasmuch as such losses, or a portion of them, could have been recognized previously as unrealized losses in shareholders' equity. The Company recognized no OTTI adjustments for the quarters and nine months ended September 30, 2013 and 2012.
	The amortized cost and estimated fair values by type and contractual maturity of fixed maturity securities are shown in the following tables. Expected maturities will differ from contractual maturities since borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

	At September 30, 2013, the Company held 385 fixed maturity and 8 equity securities in an unrealized loss position, representing 22.3% as to fixed maturities and 12.1% as to equity securities of the total number of such issues it held. At December 31, 2012, the Company held 102 fixed maturity and 14 equity securities in an unrealized loss position, representing 5.7% as to fixed maturities and 21.9% as to equity securities of the total number of such issues it held. Of the securities in an unrealized loss position, 10 and 4 fixed maturity securities and 0 and 1 equity security, had been in a continuous unrealized loss position for more than 12 months as of September 30, 2013 and December 31, 2012, respectively. The unrealized losses on these securities are primarily attributable to a post-purchase rising interest rate environment and/or a decline in the credit quality of some issuers. As part of its assessment of other-than-temporary impairments, the Company considers its intent to continue to hold and the likelihood that it will not be required to sell investment securities in an unrealized loss position until cost recovery, principally on the basis of its asset and liability maturity matching procedures.
	Fair Value Measurements - Fair value is defined as the estimated price that is likely to be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants (an exit price) at the measurement date. A fair value hierarchy is established that prioritizes the sources ("inputs") used to measure fair value into three broad levels: inputs based on quoted market prices in active markets (Level 1); observable inputs based on corroboration with available market data (Level 2); and unobservable inputs based on uncorroborated market data or a reporting entity's own assumptions (Level 3). Following is a description of the valuation methodologies and general classification used for financial instruments measured at fair value.
	The Company uses quoted values and other data provided by a nationally recognized independent pricing source as inputs into its quarterly process for determining fair values of its fixed maturity and equity securities. To validate the techniques or models used by pricing sources, the Company's review process includes, but is not limited to: (i) initial and ongoing evaluation of methodologies used by outside parties to calculate fair value; and (ii) comparing other sources including the fair value estimates to its knowledge of the current market and to independent fair value estimates provided by the investment custodian. The independent pricing source obtains market quotations and actual transaction prices for securities that have quoted prices in active markets and uses its own proprietary method for determining the fair value of securities that are not actively traded. In general, these methods involve the use of "matrix pricing" in which the independent pricing source uses observable market inputs including, but not limited to, investment yields, credit risks and spreads, benchmarking of like securities, broker-dealer quotes, reported trades and sector groupings to determine a reasonable fair value.
	Level 1 securities include U.S. and Canadian Treasury notes, publicly traded common stocks, the quoted net asset value ("NAV") mutual funds, and most short-term investments in highly liquid money market instruments. Level 2 securities generally include corporate bonds, municipal bonds, and certain U.S. and Canadian government agency securities.

There were no transfers between Levels 1, 2 or 3 during the quarter ended September 30, 2013.
Investment income is reported net of allocated expenses and includes appropriate adjustments for amortization of premium and accretion of discount on fixed maturity securities acquired at other than par value. Dividends on equity securities are credited to income on the ex-dividend date. Realized investment gains and losses, which result from sales or write-downs of securities, are reflected as revenues in the income statement and are determined on the basis of amortized value at date of sale for fixed maturity securities, and cost in regard to equity securities; such bases apply to the specific securities sold. Unrealized investment gains and losses, net of any deferred income taxes, are recorded directly as a component of accumulated other comprehensive income in shareholders' equity. At September 30, 2013, the Company and its subsidiaries had no non-income producing fixed maturity securities.
The following table reflects the composition of net investment income, net realized gains or losses, and the net change in unrealized investment gains or losses for each of the periods shown.

	Pension Plans:
	The Company has two separate defined benefit pension plans covering a portion of its work force, namely, the Old Republic International Salaried Employees Retirement Plan (the Old Republic Plan) and the PMA Capital Corporation Pension Plan (the PMA Plan). The Old Republic Plan has been closed to new entrants since December 31, 2004; the PMA plan has been frozen since December 31, 2005. During the third quarter of 2013, the Company notified participants of its intention to freeze the benefit levels in the Old Republic Plan effective December 31, 2013. The benefit curtailment triggered a revaluation of the plan which was performed as of September 30, 2013. The combined impact of the curtailment and revaluation of the plan resulted in increased operating expenses of $.6, a reduction of the pension obligation liability of $79.3, and a corresponding increase to other comprehensive income of $52.0, net of tax. Under the terms of the freeze, the plans are closed to new participants and eligible employees retain all of their rights under the plans that they have vested as of the effective date of the freeze, but do not accrue any additional benefits thereafter. Plan assets are comprised principally of bonds, common stocks and short-term investments. Cash contributions of $11.9 and $12.3 were made to the pension plans in the current quarter and first nine months of 2013, and additional cash contributions of $.4 are expected to be made in the remaining portion of calendar year 2013.

	Information About Segments of Business:
	The Company is engaged in the single business of insurance underwriting. It conducts its operations through a number of regulated insurance company subsidiaries organized into three major segments, namely its General Insurance Group (property and liability insurance), Title Insurance Group, and the Republic Financial Indemnity Group ("RFIG") Run-off Business. The results of a small life & accident insurance business are included with those of the holding company parent and minor corporate services operations. Each of the Company's segments underwrites and services only those insurance coverages which may be written by it pursuant to state insurance regulations and corporate charter provisions.
	In late March of 2012, Old Republic combined its General Insurance Group's Consumer Credit Indemnity (CCI) division with its Mortgage Guaranty (MI) line within a business denoted as the RFIG run-off segment. The two operations, which offer similar insurance coverages, have been in run-off operating mode since 2008 (CCI) and August 2011 (MI), and are inactive from new business production standpoints. The combination affects the manner in which segmented information is presented herein. The operating results of the combined coverages are therefore shown as a single run-off book of business within the Company's consolidated operations. Segment results exclude net realized investment gains or losses and other-than-temporary impairments as these are aggregated in the consolidated totals. The contributions of Old Republic's insurance industry segments to consolidated totals are shown in the following table.

__________
(a)	Income (loss) before taxes (credits) is reported net of interest charges on intercompany financing arrangements with Old Republic's holding company parent for the following segments: General - $7.2 and $21.5 compared to $7.1 and $21.0 for the quarter and nine months ended September 30, 2013 and 2012, respectively; Title - $1.9 and $5.9 compared to $2.0 and $6.0 for the quarter and nine months ended September 30, 2013 and 2012, respectively, and RFIG run-off - $0 and $0 compared to $(2.1) and $2.1 for the quarter and nine months ended September 30, 2013 and 2012, respectively.
(b)	Represents amounts for Old Republic's holding company parent, minor corporate services subsidiaries, and a small life and accident insurance operation.
General Insurance results for the third quarter and first nine months of 2012 reflect pretax charges of approximately $9 and $31, respectively, related to previously deferred acquisition costs ("DAC"). The DAC charge stemmed from new accounting guidance issued by the FASB which became effective as of January 1, 2012.
The material increases in mortgage guaranty insurance claims and loss payments that began in 2007 gradually depleted Republic Mortgage Insurance Company's ("RMIC") statutory capital base and forced it to discontinue writing new business. The insurance laws of 16 jurisdictions, including RMIC's and its affiliate company, Republic Mortgage Insurance Company of North Carolina's ("RMICNC") domiciliary state of North Carolina, require a mortgage insurer to maintain a minimum amount of statutory capital relative to risk in force (or a similar measure) in order to continue to write new business. The formulations currently allow for a maximum risk-to-capital ratio of 25 to 1, or alternatively stated, a "minimum policyholder position" ("MPP") of one-twenty-fifth of the total risk in force. The failure to maintain the prescribed minimum capital level in a particular state generally requires a mortgage insurer to immediately stop writing new business until it reestablishes the required level of capital or receives a waiver of the requirement from a state's insurance regulatory authority. RMIC breached the minimum capital requirement during the third quarter of 2010. RMIC had previously requested and, subsequently received waivers or forbearance of the minimum policyholder position requirements from the regulatory authorities in substantially all affected states. Following several brief extensions, the waiver from its domiciliary state of North Carolina expired on August 31, 2011, and RMIC and RMICNC, discontinued writing new business in all states and limited themselves to servicing the run-off of their existing business.
During 2012 the North Carolina Department of Insurance ("NCDOI") issued several orders the ultimate effects of which were:
• To place RMIC and RMICNC under NCDOI supervision;
• To approve a Corrective Plan submitted by RMIC pursuant to which all settled claims are to be paid in cash for 60% of the settled amount, with the remaining 40% retained in claim reserves as a Deferred Payment Obligation ("DPO") until a future payment of all or a portion of this 40% is approved by the NCDOI; and
• To execute the DPO-based run-off plan under Old Republic's ownership and NCDOI supervision of RMIC and RMICNC to effect a most economically sound realization of ultimate benefits to policyholders during a sufficiently long future period.
As of September 30, 2013, the accumulated DPO claim reserve amounted to $502.2.

Commitments and Contingent Liabilities	'
	Commitments and Contingent Liabilities:
	Legal proceedings against the Company and its subsidiaries routinely arise in the normal course of business and usually pertain to claim matters related to insurance policies and contracts issued by its insurance subsidiaries. Other, non-routine legal proceedings which may prove to be material to the Company or a subsidiary are discussed below.
	Purported class action lawsuits are pending against the Company's principal title insurance subsidiary, Old Republic National Title Insurance Company ("ORNTIC"), in federal courts in two states - Pennsylvania (Markocki et al. v. ORNTIC, U.S. District Court, Eastern District, Pennsylvania, filed June 8, 2006), and Texas (Ahmad et al. v. ORNTIC, U.S. District Court, Northern District, Texas, Dallas Division, filed February 8, 2008). The plaintiffs allege that ORNTIC failed to give consumers reissue and/or refinance credits on the premiums charged for title insurance covering mortgage refinancing transactions, as required by rate schedules filed by ORNTIC or by state rating bureaus with the state insurance regulatory authorities. The Pennsylvania suit also alleges violations of the federal Real Estate Settlement Procedures Act ("RESPA"). The Court in the Texas suit dismissed similar RESPA allegations. Classes have been certified in the Pennsylvania suit, but the 5th Circuit Court of Appeals has reversed the earlier class certification in the Texas case.
	On December 19, 2008, Old Republic Insurance Company and Old Republic Insured Credit Services, Inc., ("Old Republic") filed suit against Countrywide Bank FSB, Countrywide Home Loans, Inc. ("Countrywide") and Bank of New York Mellon, BNY Mellon Trust of Delaware ("BNYM") in the Circuit Court, Cook County, Illinois (Old Republic Insurance Company, et al. v. Countrywide Bank FSB, et al.) seeking rescission of various credit indemnity policies issued to insure home equity loans and home equity lines of credit which Countrywide had securitized or held for its own account, a declaratory judgment and money damages based upon material misrepresentations either by Countrywide as to the credit characteristics of the loans or by the borrowers in their loan applications. Countrywide filed a counterclaim alleging a breach of contract, bad faith and seeking a declaratory judgment challenging the factual and procedural bases that Old Republic had relied upon to deny or rescind coverage for individual defaulted loans under those policies, as well as unspecified compensatory and punitive damages. The Court ruled that Countrywide does not have standing to counterclaim with respect to the policies insuring the securitized loans because those policies were issued to BNYM. In response, Countrywide and BNYM have jointly filed a motion asking the Court to allow an amended counterclaim in which BNYM would raise substantially similar allegations as those raised by Countrywide and make substantially similar requests but with respect to the policies issued to BNYM. The Court has not yet ruled on their motion.
	On November 3, 2010, Bank of America, N.A. ("B of A") filed suit against Old Republic Insurance Company ("ORIC") in the U.S. District Court for the Western District of North Carolina (Bank of America, N.A. v. Old Republic Insurance Company) alleging breach of contract, breach of the duty of good faith and fair dealing and bad faith with respect to ORIC's handling of certain claims under a policy of credit indemnity insurance issued to B of A. The policy is not related to those issued to Countrywide, which are the subject of the above-noted separate litigation. The B of A suit seeks a declaratory judgment with respect to the interpretation of certain policy terms, B of A's compliance with certain terms and conditions of the policy, and the propriety of certain positions and procedures taken by ORIC in response to claims filed by B of A. The suit also seeks unspecified money damages, pre and post judgment interest and punitive damages. On January 23, 2012, ORIC filed a counterclaim seeking damages based on B of A's alleged interference with ORIC's subrogation rights.
	On December 31, 2009, two of the Company's mortgage insurance subsidiaries, Republic Mortgage Insurance Company and Republic Mortgage Insurance Company of North Carolina (together "RMIC") filed a Complaint for Declaratory Judgment in the Supreme Court of the State of New York, County of New York, against Countrywide Financial Corporation, Countrywide Home Loans, Inc., The Bank of New York Mellon Trust Company, N.A., BAC Home Loans Servicing, LP, and Bank of America N.A. as successor in interest to Countrywide Bank, N.A. (together "Countrywide")(Republic Mortgage Insurance Company, et al. v. Countrywide Financial Corporation, et al.). The suit relates to five mortgage insurance master policies (the "Policies") issued by RMIC to Countrywide or to the Bank of New York Mellon Trust Company as co-trustee for trusts containing securitized mortgage loans that were originated or purchased by Countrywide. RMIC has rescinded its mortgage insurance coverage on over 1,500 of the loans originally covered under the Policies based upon material misrepresentations of the borrowers in their loan applications or the negligence of Countrywide in its loan underwriting practices or procedures. Each of the coverage rescissions occurred after a borrower had defaulted and RMIC reviewed the claim and loan file submitted by Countrywide. The suit seeks the Court's review and interpretation of the Policies' incontestability provisions and its validation of RMIC's investigation procedures with respect to the claims and underlying loan files.
	On January 29, 2010, in response to RMIC's suit, Countrywide served RMIC with a demand for arbitration under the arbitration clauses of the same Policies. The demand raises largely the same issues as those raised in RMIC's suit against Countrywide, but from Countrywide's perspective, as well as Countrywide's and RMIC's compliance with the terms, provisions and conditions of the Policies. The demand includes a prayer for punitive, compensatory and consequential damages. RMIC filed a motion to stay the arbitration, and Countrywide filed a motion to dismiss RMIC's lawsuit and to compel the arbitration. On July 26, 2010, the Court granted Countrywide's motion, ordering the matters be submitted to arbitration and dismissing the lawsuit. The arbitration is proceeding.
	On December 30, 2011 and on January 4, 2013, purported class action suits alleging RESPA violations were filed in the Federal District Court, for the Eastern District of Pennsylvania targeting RMIC, other mortgage guaranty insurance companies, PNC Financial Services Group (as successor to National City Bank) and HSBC Bank USA, N.A., and their wholly-owned captive insurance subsidiaries. (White, Hightower, et al. v. PNC Financial Services Group (as successor to National City Bank) et al.), (Ba, Chip, et al. v. HSBC Bank USA, N.A., et al.). The lawsuits are two of twelve against various lenders, their captive reinsurers and the mortgage insurers, filed by the same law firms, all of which were substantially identical in alleging that the mortgage guaranty insurers had reinsurance arrangements with the defendant banks' captive insurance subsidiaries under which payments were made in violation of the anti-kickback and fee splitting prohibitions of Sections 8(a) and 8(b) of RESPA. Ten of the twelve suits have been dismissed. The remaining suits seek unspecified damages, costs, fees and the return of the allegedly improper payments. A class has not been certified in either suit and RMIC has filed motions to dismiss the cases.
	On September 26, 2012 a purported national class action suit was filed against Old Republic Home Protection Company in the Superior Court of California for Riverside County. (Friedman v. Old Republic Home Protection Company, Inc.). The suit alleges that the Company operates in breach of its home warranty contracts, in breach of implied covenants of good faith and fair dealing, in violation of various provisions of the California Civil Code and Business and Professions Code and is guilty of false advertising. The stated class period is from November 24, 2004 through the present. The suit seeks declaratory relief, injunctive relief, restitution, damages, costs and attorneys' fees in unspecified amounts. The firm representing the plaintiff had previously filed similar suits against the Company, which were unsuccessful. The Company succeeded in having the case removed to the U.S. District Court for the Central District of California on October 24, 2012, and believes it has strong defenses to the allegations and to the certification of any class in this matter.
	PNC Bank, N.A., in its own right and as successor-in-interest to National City Corporation, filed suit against RMIC on October 10, 2012 in the United States District Court for the Western District of Pennsylvania disputing RMIC's denials and rescissions of its mortgage guaranty insurance coverage on an unspecified number of mortgage loans. It filed an amended complaint on January 30, 2013 identifying 248 disputed coverage denials or rescissions (PNC Bank, N.A. v. Republic Mortgage Insurance Company). The suit seeks certain declaratory relief, actual money damages and unspecified compensatory, consequential and punitive damages.
	On May 16, 2013, Bank of America, N.A. ("B of A") filed a demand for arbitration with the American Arbitration Association against both Republic Mortgage Insurance Company and Republic Mortgage Insurance Company of North Carolina (together, "RMIC") under the arbitration provisions of the RMIC Master Policy of mortgage guaranty insurance issued to B of A. The demand relates to RMIC's denials of certain claims and rescissions of coverage as to other claims. B of A alleges RMIC's actions were in breach of contract, in breach of RMIC's duty of good faith and fair dealing and in bad faith. The allegations are substantially similar to those raised by B of A's affiliates, Countrywide Financial Corporation and Countrywide Home Loans, Inc. in their arbitration demand against RMIC. B of A is a plaintiff in that proceeding as well, in its capacity as successor in interest to Countrywide Bank, N.A. B of A's demand requests a declaratory judgment with respect to the interpretation of certain policy provisions, B of A's compliance with certain terms and conditions of the policy, and the propriety of certain coverage positions and claims administration procedures of RMIC. The demand also seeks unspecified money damages, punitive, compensatory and consequential damages, interest, attorney's fees and costs.
	Under GAAP, an estimated loss is accrued only if the loss is probable and reasonably estimable. The Company and its subsidiaries have defended and intend to continue defending vigorously against each of the aforementioned actions. The Company does not believe it probable that any of these actions will have a material adverse effect on its consolidated financial position, results of operations, or cash flows, though there can be no assurance in those regards. Except as otherwise noted, the Company is unable to make a reasonable estimate or range of estimates of any potential liability under these lawsuits, the counterclaim, and the arbitration, all of which seek unquantified damages, attorneys' fees, and expenses. It is also unclear what effect, if any, the run-off operations of RMIC and the depletion of its capital will have in the actions against it.

	Consolidated debt of Old Republic and its subsidiaries is summarized below:
		September 30, 2013						December 31, 2012
		Carrying			Fair			Carrying			Fair
		Amount			Value			Amount			Value
	3.75% Convertible Senior Notes due 2018	$	550		$	643.5		$	550		$	568.5
	ESSOP debt with an average yield of 3.70%
	and 3.74%, respectively	18			18			20.8			20.8
	Other miscellaneous debt	1.1			1.1			2			2
	Total debt	$	569.2		$	662.7		$	572.9		$	591.5
	The Company completed a public offering of $550.0 aggregate principal amount of Convertible Senior Notes in early March, 2011. The notes bear interest at a rate of 3.75% per year, mature on March 15, 2018, and are convertible at any time prior to maturity by the holder into 64.3407 shares (subject to periodic adjustment under certain circumstances) of common stock per one thousand dollar note.
	The Company's 3.75% Convertible Senior Notes ("the Notes") contain provisions defining certain events of default, among them a court ordered proceeding due to the insolvency of a Significant Subsidiary. The Notes define Significant Subsidiary in accordance with the paragraph (w) of Rule 1-02 of the SEC's Regulation S-X. The Company's flagship mortgage guaranty insurance carrier, RMIC qualifies as a Significant Subsidiary for purposes of the Notes. If RMIC were to become statutorily impaired, its insolvency could trigger a receivership proceeding which, in turn could ultimately result in an event of default. If this were to occur, the outstanding principal of the Notes could become immediately due and payable. Management believes the Orders issued by the North Carolina Department of Insurance to RMIC has precluded such an event from occurring for the foreseeable future. Moreover, RMIC is expected to be increasingly less significant as its run-off book extinguishes itself. While Old Republic believes that it would have access to the capital markets or otherwise mitigate an event of default under the Notes, there is no assurance that it would be able to do so under future stressful capital market conditions.
	At September 30, 2013, the Company had sufficient liquid resources available to redeem a substantial portion of the 3.75% Notes. Management continues to explore the Company's options to address possibly greater liquidity needs in the circumstance that an event of default was to occur at a future date. These potential plans include an amendment to the 3.75% Notes removing RMIC from the definition of a Significant Subsidiary, an additional capital raise through issuance of new straight or convertible debt, or the utilization of intra system dividend and financing capacity. While Management is confident that an event of default can be stemmed, there is no assurance that its impact could be addressed through execution of these plans.
	Fair Value Measurements - The Company utilizes indicative market prices, which incorporate recent actual market transactions and current bid/ask quotations to estimate the fair value of outstanding debt securities that are classified within Level 2 of the fair value hierarchy as presented below. The Company uses an internally generated interest yield market matrix table, which incorporates maturity, coupon rate, credit quality, structure and current market conditions to estimate the fair value of its outstanding debt securities that are classified within Level 3.
	The following table shows a summary of the carrying value and fair value of financial liabilities segregated among the various input levels described in Note 3 above:
			Carrying			Fair
			Value			Value			Level 1			Level 2		Level 3
	Financial Liabilities:

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	Income Taxes:
	Tax positions taken or expected to be taken in a tax return by the Company are recognized in the financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. To the best of management's knowledge, there are no tax uncertainties that are expected to result in significant increases or decreases to unrecognized tax benefits within the next twelve month period. The Company views its income tax exposures as primarily consisting of timing differences whereby the ultimate deductibility of a taxable amount is highly certain but the timing of its deductibility is uncertain. Such differences relate principally to the timing of deductions for loss and premium reserves. As in prior examinations, the Internal Revenue Service ("IRS") could assert that claim reserve deductions were overstated thereby reducing the Company's statutory taxable income in any particular year. The Company believes that it establishes its reserves fairly and consistently at each balance sheet date, and that it would succeed in defending its tax position in these regards. Because of the impact of deferred tax accounting, the possible accelerated payment of tax to the IRS would not necessarily affect the annual effective tax rate. The Company's 2005 through 2010 consolidated Federal income tax returns, including amendments relative to claims for recovery of taxes previously paid, have been examined by the IRS. All adjustments presented by the Company were accepted. The Company classifies interest and penalties as income tax expense in the consolidated statement of income.

Subsequent Events [Abstract]	'
Subsequent Event	'
	Subsequent Event:
	On October 24, 2013 the Company announced a plan of recapitalization by its RMIC Companies, Inc. ("RMICC") mortgage guaranty subsidiary. RMICC plans to raise new funds in the capital markets and use substantially all of these to recapitalize its three mortgage insurance carriers. The additional capital is intended to enable these carriers to at once fully support existing policies, to pay off deferred claim obligations, to exit a current state of supervision under North Carolina insurance regulations, and to resume underwriting of new business early in 2014. In connection with such a transaction, it is expected that Old Republic would contribute up to $50.0 of this new capital. Upon the successful closing of this transaction, Old Republic's continuing interest in RMICC and the mortgage guaranty business will consist of a non-controlling equity interest in RMICC's equity capital.
	Completion of the transaction will be subject to market conditions and other factors. Moreover, the addition of the new funds to RMICC and its subsidiaries will be contingent on the receipt of certain regulatory approvals. The most essential of these will be required from the North Carolina Department of Insurance ("NCDOI"), and from Fannie Mae and Freddie Mac with any necessary assent of their FHFA Conservator.
