	Consolidation and Basis of Presentation
	The condensed consolidated financial statements include the accounts of Mercury General Corporation and its subsidiaries (referred to herein collectively as the “Company”). For the list of the Company’s subsidiaries, see Note 1 “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	The condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), which differ in some respects from those filed in reports to insurance regulatory authorities. All intercompany transactions and balances have been eliminated.
	The financial data of the Company included herein are unaudited. In the opinion of management, all material adjustments of a normal recurring nature have been made to present fairly the Company’s financial position at March 31, 2014 and the results of operations, comprehensive income, and cash flows for the periods presented. These statements were prepared in accordance with the instructions for interim reporting and do not contain certain information that was included in the annual financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 for more complete descriptions and discussions. Operating results and cash flows for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates require the Company to apply complex assumptions and judgments, and often the Company must make estimates about effects of matters that are inherently uncertain and will likely change in subsequent periods. The most significant assumptions in the preparation of these condensed consolidated financial statements relate to reserves for losses and loss adjustment expenses. Actual results could differ from those estimates (See Note 1 “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013).
	Earnings per Share
	Potentially dilutive securities representing approximately 48,000 and 109,000 shares of common stock for the three months ended March 31, 2014 and 2013, respectively, were excluded from the computation of diluted earnings per common share for these periods because their effect would have been anti-dilutive.
	Deferred Policy Acquisition Costs
	Deferred policy acquisition costs consist of commissions paid to outside agents, premium taxes, salaries, and certain other underwriting costs that are incremental or directly related to the successful acquisition of new and renewal insurance contracts and are amortized over the life of the related policy in proportion to premiums earned. Deferred policy acquisition costs are limited to the amount that will remain after deducting from unearned premiums and anticipated investment income, the estimated losses and loss adjustment expenses, and the servicing costs that will be incurred as premiums are earned. The Company’s deferred policy acquisition costs are further limited by excluding those costs not directly related to the successful acquisition of insurance contracts. Deferred policy acquisition cost amortization was $129.8 million and $123.7 million for the three months ended March 31, 2014 and 2013, respectively. The Company does not defer advertising expenditures but expenses them as incurred. The Company recorded net advertising expenses of approximately $6 million for each of the three month periods ended March 31, 2014 and 2013.
	Total Return Swap
	During the first quarter of 2014, the Company formed and consolidated a special purpose investment vehicle, Fannette Funding LLC (“FFL”). The Company is the sole managing member in FFL. On February 13, 2014, FFL entered into a three-year total return swap agreement with Citibank, N.A. (“Citibank”). Under the total return swap agreement, FFL receives the income equivalent on underlying obligations due to Citibank and pays to Citibank interest equal to LIBOR plus 140 basis points on the outstanding notional amount of the underlying obligations, which was approximately $38 million as of March 31, 2014. The total return swap agreement is secured by approximately $30 million of U.S. Treasuries as collateral, which are included in short-term investments on the consolidated balance sheets. In the event of a significant erosion in market value, FFL’s position in the loan portfolio will be reduced and the Company has the option to add additional capital or terminate the total return swap agreement.

	Recently Issued Accounting Standards
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued a new standard that requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when the uncertain tax position would reduce the net operating loss or other carryforward under the tax law of the applicable jurisdiction and when the entity intends to use the deferred tax asset for that purpose. The Company adopted the new standard which became effective for the interim period ended March 31, 2014. The adoption of the new standard did not have a material impact on the Company’s consolidated financial statements.

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The financial instruments recorded in the consolidated balance sheets include investments, receivables, total return swaps, accounts payable, equity contracts, and secured and unsecured notes payable. Due to their short-term maturity, the carrying values of receivables and accounts payable approximate their fair market values. The following table presents the estimated fair values of financial instruments at March 31, 2014 and December 31, 2013.
		March 31, 2014		December 31, 2013
		(Amounts in thousands)
	Assets
	Investments	$	3,316,704	$	3,158,312
	Total return swaps	$	1,499	$	1,650
	Liabilities
	Equity contracts	$	426	$	140
	Secured notes	$	140,000	$	140,000
	Unsecured note	$	130,000	$	50,000
	Methods and assumptions used in estimating fair values are as follows:
	Investments
	The Company applies the fair value option to all fixed maturity and equity securities and short-term investments at the time an eligible item is first recognized. The cost of investments sold is determined on a first-in and first-out method and realized gains and losses are included in net realized investment gains. For additional disclosures regarding methods and assumptions used in estimating fair values of these securities, see Note 5.
	Total return swaps
	The fair values of the total return swaps reflect the estimated amounts that, upon termination of the contracts, would be received for selling an asset or paid to transfer a liability in an orderly transaction at March 31, 2014 and December 31, 2013 based on models using inputs, such as interest rate yield curves and credit spreads, observable for substantially the full term of the contract. For additional disclosures regarding methods and assumptions used in estimating fair values, see Note 5.
	Equity contracts
	The fair value of equity contracts is based on quoted prices for identical instruments in active markets. For additional disclosures regarding methods and assumptions used in estimating fair values of equity contracts, see Note 5.
	Secured notes payable
	The fair value of the Company’s $120 million and $20 million secured notes, classified as Level 2 in the fair value hierarchy described in Note 5, is estimated based on assumptions and inputs, such as the market value of underlying collateral and reset rates, for similarly termed notes that are observable in the market.
	Unsecured note payable
	The fair value of the Company’s $130 million unsecured note, classified as Level 2 in the fair value hierarchy described in Note 5, is based on the unadjusted quoted price for similar notes in active markets.

Fair Value Option	'
	Fair Value Option
	Gains and losses due to changes in fair value for items measured at fair value pursuant to application of the fair value option are included in net realized investment gains in the Company’s consolidated statements of operations, while interest and dividend income on investment holdings are recognized on an accrual basis on each measurement date and are included in net investment income in the Company’s consolidated statements of operations. The primary reasons for electing the fair value option were simplification and cost-benefit considerations as well as the expansion of the use of the Company’s fair value measurement consistent with the long-term measurement objectives of the FASB for accounting for financial instruments.
	The following table presents gains (losses) due to changes in fair value of investments that are measured at fair value pursuant to application of the fair value option:

Financial Instruments, Financial Assets, Balance Sheet Groupings [Abstract]	'
Fair Value Measurement	'
	Fair Value Measurement
	The Company employs a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date using the exit price. Accordingly, when market observable data are not readily available, the Company’s own assumptions are used to reflect those that market participants would be presumed to use in pricing the asset or liability at the measurement date. Assets and liabilities recorded on the consolidated balance sheets at fair value are categorized based on the level of judgment associated with inputs used to measure their fair value and the level of market price observability, as follows:
	Level 1	Unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date.
	Level 2	Pricing inputs are other than quoted prices in active markets, which are based on the following:
		•     Quoted prices for similar assets or liabilities in active markets;
		•     Quoted prices for identical or similar assets or liabilities in non-active markets; or
		•     Either directly or indirectly observable inputs as of the reporting date.
	Level 3	Pricing inputs are unobservable and significant to the overall fair value measurement, and the determination of fair value requires significant management judgment or estimation.
	In certain cases, inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Thus, a Level 3 fair value measurement may include inputs that are observable (Level 1 or Level 2) and unobservable (Level 3). The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset or liability.
	The Company uses prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the ability to observe prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2, or from Level 2 to Level 3. The Company recognizes transfers between levels at either the actual date of the event or a change in circumstances that caused the transfer.
	Summary of Significant Valuation Techniques for Financial Assets and Financial Liabilities
	The Company’s fair value measurements are based on the market approach, which utilizes market transaction data for the same or similar instruments.
	The Company obtained unadjusted fair values on 99.6% of its portfolio from an independent pricing service. For 0.4% of its portfolio, classified as Level 3, the Company obtained specific unadjusted broker quotes based on net fund value and, to a lesser extent, unobservable inputs from at least one knowledgeable outside security broker to determine the fair value as of March 31, 2014.
	Level 1 Measurements - Fair values of financial assets and financial liabilities are obtained from an independent pricing service, and are based on unadjusted quoted prices for identical assets or liabilities in active markets. Additional pricing services and closing exchange values are used as a comparison to ensure that reasonable fair values are used in pricing the investment portfolio.
	U.S. government bonds and agencies/Short-term bonds: Valued using unadjusted quoted market prices for identical assets in active markets.
	Common stock: Comprised of actively traded, exchange listed U.S. and international equity securities and valued based on unadjusted quoted prices for identical assets in active markets.
	Money market instruments: Valued based on unadjusted quoted prices for identical assets.
	Equity contracts: Comprised of free-standing exchange listed derivatives that are actively traded and valued based on quoted prices for identical instruments in active markets.
	Level 2 Measurements - Fair values of financial assets and financial liabilities are obtained from an independent pricing service or outside brokers, and are based on prices for similar assets or liabilities in active markets or valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. Additional pricing services are used as a comparison to ensure reliable fair values are used in pricing the investment portfolio.
	Municipal securities: Valued based on models or matrices using inputs such as quoted prices for identical or similar assets in active markets.
	Mortgage-backed securities: Comprised of securities that are collateralized by mortgage loans and valued based on models or matrices using multiple observable inputs, such as benchmark yields, reported trades and broker/dealer quotes, for identical or similar assets in active markets. The Company had holdings of $21.9 million at each of March 31, 2014 and December 31, 2013, in commercial mortgage-backed securities.
	Corporate securities/Short-term bonds: Valued based on a multi-dimensional model using multiple observable inputs, such as benchmark yields, reported trades, broker/dealer quotes and issue spreads, for identical or similar assets in active markets.
	Non-redeemable preferred stock: Valued based on observable inputs, such as underlying and common stock of same issuer and appropriate spread over a comparable U.S. Treasury security, for identical or similar assets in active markets.
	Total return swaps: Valued based on models using inputs such as interest rate yield curves, underlying debt/credit instruments and the appropriate benchmark spread for similar assets in active markets, observable for substantially the full term of the contract.
	Level 3 Measurements - Fair values of financial assets are based on inputs that are both unobservable and significant to the overall fair value measurement, including any items in which the evaluated prices obtained elsewhere were deemed to be of a distressed trading level.
	Collateralized debt obligations/Partnership interest in a private credit fund: Valued based on underlying debt/credit instruments and the appropriate benchmark spread for similar assets in active markets; taking into consideration unobservable inputs related to liquidity assumptions.
	The Company’s financial instruments at fair value are reflected in the consolidated balance sheets on a trade-date basis. Related unrealized gains or losses are recognized in net realized investment gains in the consolidated statements of operations. Fair value measurements are not adjusted for transaction costs.
	The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013, and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value:

General Discussion of Derivative Instruments and Hedging Activities [Abstract]	'
Derivative Financial Instruments	'
	Derivative Financial Instruments
	The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are equity price risk and interest rate risk. Equity contracts on various equity securities are intended to manage the price risk associated with forecasted purchases or sales of such securities. Interest rate swaps are intended to manage the interest rate risk associated with the Company’s debts with fixed or floating rates.
	On March 3, 2008, the Company entered into an interest rate swap of its floating LIBOR rate on a Bank of America $18 million LIBOR plus 50 basis points loan for a fixed rate of 4.25% that matured on March 1, 2013. On October 4, 2011, the Company refinanced the $18 million loan that was scheduled to mature on March 1, 2013 with a Union Bank $20 million LIBOR plus 40 basis points loan that matures on January 2, 2015. The related swap expired on March 1, 2013.
	The Company also enters into derivative contracts to enhance returns on its investment portfolio.
	On February 13, 2014, FFL entered into a three-year total return swap agreement with Citibank. Under the total return swap agreement, FFL receives the income equivalent on underlying obligations due to Citibank and pays to Citibank interest equal to LIBOR plus 140 basis points on the outstanding notional amount of the underlying obligations, which was approximately $38 million as of March 31, 2014. The total return swap is secured by approximately $30 million of U.S. Treasuries as collateral, which are included in short-term investments on the consolidated balance sheets.
	On August 9, 2013, Animas Funding LLC (“AFL”) entered into a three-year total return swap agreement with Citibank. Under the total return swap agreement, AFL receives the income equivalent on underlying obligations due to Citibank and pays to Citibank interest equal to LIBOR plus 120 basis points on the outstanding notional amount of the underlying obligations, which was approximately $159 million as of March 31, 2014. The total return swap is secured by approximately $40 million of U.S. Treasuries as collateral, which are included in short-term investments on the consolidated balance sheets.

	Most equity contracts consist of covered calls. The Company writes covered calls on underlying equity positions held as an enhanced income strategy that is permitted for the Company’s insurance subsidiaries under statutory regulations. The Company manages the risk associated with covered calls through strict capital limitations and asset diversification throughout various industries. For additional disclosures regarding equity contracts, see Note 5.

Share-based Compensation, Allocation and Classification in Financial Statements [Abstract]	'
Share-Based Compensation	'
	Share-Based Compensation
	Share-based compensation expense for all share-based payment awards granted or modified is based on the estimated grant-date fair value. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is the option vesting term of four or five years for options granted prior to 2008 and four years for options granted subsequent to January 1, 2008, for only those shares expected to vest. The fair value of stock option awards is estimated using the Black-Scholes option pricing model with the grant-date assumptions and weighted-average fair values.
	Under the Company’s 2005 Incentive Award Plan (the “Plan”), the Compensation Committee of the Company’s Board of Directors granted performance vesting restricted stock units to the Company’s senior management and key employees as follows:
		Grant Year
		2014	2013	2012
	Three-year performance period ending December 31,	2016	2015	2014
	Vesting shares, target	91,500	84,500	89,000
	Vesting shares, maximum	171,563	190,125	200,250
	The restricted stock units vest at the end of a three-year performance period beginning with the year of the grant, and then only if, and to the extent that, the Company’s performance during the performance period achieves the threshold established by the Compensation Committee of the Company’s Board of Directors. For 2012 grants, vesting will be based on the Company’s cumulative underwriting income and net premium written growth. For 2013 and 2014 grants, vesting will be based on the Company’s cumulative underwriting income, annual underwriting income, and net earned premium growth.
	The fair value of each restricted share grant was determined based on the market price on the grant date. Compensation cost is recognized based on management’s best estimate that performance goals will be achieved. If such goals are not met, no compensation cost is recognized and any recognized compensation cost would be reversed. For 2012 grants, the achievement of the performance condition set by the Compensation Committee was no longer considered probable, and previously recognized compensation costs were reversed.

Components of Income Tax Expense (Benefit), Continuing Operations [Abstract]	'
Income Taxes	'
	Income Taxes
	For financial statement purposes, the Company recognizes tax benefits related to positions taken, or expected to be taken, on a tax return only if, “more-likely-than-not,” the positions are sustainable. Once this threshold has been met, the Company’s measurement of its expected tax benefits is recognized in its financial statements.
	There was a $0.2 million increase to the total amount of unrecognized tax benefit related to tax uncertainties during the three months ended March 31, 2014. The increase was the result of tax positions taken regarding state tax apportionment issues based on management’s best judgment given the facts, circumstances, and information available at the reporting date. The Company does not expect any changes in such unrecognized tax benefits to have a significant impact on its consolidated financial statements within the next 12 months.
	The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states. Tax years that remain subject to examination by major taxing jurisdictions are 2010 through 2012 for federal taxes and 2003 through 2012 for California state taxes. The Company is currently under examination by the California Franchise Tax Board (“FTB”) for tax years 2003 through 2010. The FTB issued Notices of Proposed Assessments to the Company for tax years 2003 through 2006, which were affirmed following an administrative protest process with the FTB examination. The Company is considering its options for resolving the case. No assessments have been received for tax years 2007 through 2010. Management believes that the resolution of these examinations and assessments will not have a material impact on the consolidated financial statements.
	Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial reporting basis and the respective tax basis of the Company’s assets and liabilities, and expected benefits of utilizing net operating loss, capital loss, and tax-credit carryforwards. The Company assesses the likelihood that its deferred tax assets will be realized and, to the extent management does not believe these assets are more likely than not to be realized, a valuation allowance is established.
	At March 31, 2014, the Company’s deferred income taxes were in a net liability position which included a combination of ordinary and capital deferred tax benefits. In assessing the realizability of this component of the total deferred tax balance which consists of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon generating sufficient taxable income of the appropriate character within the carryback and carryforward periods available under the tax law. Management considers the reversal of deferred tax liabilities, projected future taxable income of an appropriate nature, and tax-planning strategies in making this assessment. The Company believes that through the use of prudent tax planning strategies and the generation of capital gains, sufficient income will be realized in order to maximize the full benefits of its deferred tax assets. Although realization is not assured, management believes that it is more likely than not that the Company’s deferred tax assets will be realized.

Contingencies	'
	Contingencies
	The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Company’s reserving methods, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	The Company also establishes reserves for non-insurance claims related lawsuits, regulatory actions, and other contingencies when the Company believes a loss is probable and is able to estimate its potential exposure. For material loss contingencies believed to be reasonably possible, the Company also discloses the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. While actual losses may differ from the amounts recorded and the ultimate outcome of the Company’s pending actions is generally not yet determinable, the Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition, results of operations, or cash flows.
	In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate. For a discussion of legal matters, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

	The condensed consolidated financial statements include the accounts of Mercury General Corporation and its subsidiaries (referred to herein collectively as the “Company”). For the list of the Company’s subsidiaries, see Note 1 “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	The condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), which differ in some respects from those filed in reports to insurance regulatory authorities. All intercompany transactions and balances have been eliminated.
	The financial data of the Company included herein are unaudited. In the opinion of management, all material adjustments of a normal recurring nature have been made to present fairly the Company’s financial position at March 31, 2014 and the results of operations, comprehensive income, and cash flows for the periods presented. These statements were prepared in accordance with the instructions for interim reporting and do not contain certain information that was included in the annual financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 for more complete descriptions and discussions. Operating results and cash flows for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates require the Company to apply complex assumptions and judgments, and often the Company must make estimates about effects of matters that are inherently uncertain and will likely change in subsequent periods. The most significant assumptions in the preparation of these condensed consolidated financial statements relate to reserves for losses and loss adjustment expenses. Actual results could differ from those estimates (See Note 1 “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013).
Earnings per Share	'
	Earnings per Share
	Potentially dilutive securities representing approximately 48,000 and 109,000 shares of common stock for the three months ended March 31, 2014 and 2013, respectively, were excluded from the computation of diluted earnings per common share for these periods because their effect would have been anti-dilutive.
Deferred Policy Acquisition Costs	'
	Deferred Policy Acquisition Costs
	Deferred policy acquisition costs consist of commissions paid to outside agents, premium taxes, salaries, and certain other underwriting costs that are incremental or directly related to the successful acquisition of new and renewal insurance contracts and are amortized over the life of the related policy in proportion to premiums earned. Deferred policy acquisition costs are limited to the amount that will remain after deducting from unearned premiums and anticipated investment income, the estimated losses and loss adjustment expenses, and the servicing costs that will be incurred as premiums are earned. The Company’s deferred policy acquisition costs are further limited by excluding those costs not directly related to the successful acquisition of insurance contracts. Deferred policy acquisition cost amortization was $129.8 million and $123.7 million for the three months ended March 31, 2014 and 2013, respectively. The Company does not defer advertising expenditures but expenses them as incurred. The Company recorded net advertising expenses of approximately $6 million for each of the three month periods ended March 31, 2014 and 2013.
