Earnings Per Share [Abstract]	'
Net Income Per Share	'
	NOTE 3· Net Income Per Share
	Accounting Standards Codification (“ASC”) Topic 260 — Earnings Per Share is the authoritative guidance that states that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities and, therefore, are included in computing earnings per share (“EPS”) pursuant to the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends or dividend equivalents and their respective participation rights in undistributed earnings. Performance stock shares granted to employees under the Company’s Performance Stock Plan and Stock Incentive Plan are considered participating securities as they receive non-forfeitable dividend equivalents at the same rate as common stock.
	Basic EPS is computed based on the weighted average number of common shares (including participating securities) issued and outstanding during the period. Diluted EPS is computed based on the weighted average number of common shares issued and outstanding plus equivalent shares assuming the exercise of stock options. The dilutive effect of stock options is computed by application of the treasury stock method. The following is a reconciliation between basic and diluted weighted average shares outstanding:

	Acquisitions in 2013
	During the nine months ended September 30, 2013, Brown & Brown has acquired the assets and assumed certain liabilities of three insurance intermediaries, all of the stock of one insurance intermediary and a book of business (customer accounts). The aggregate purchase price of these acquisitions was $484,319,000, including $379,694,000 of cash payments, the issuance of $85,000 in other payables, the assumption of $101,755,000 of liabilities and $2,785,000 of recorded earn-out payables. All of these acquisitions were acquired primarily to expand Brown & Brown’s core businesses and to attract and hire high-quality individuals. Acquisition purchase prices are typically based on a multiple of average annual operating profit earned over a one- to three-year period within a minimum and maximum price range. The recorded purchase price for all acquisitions consummated after January 1, 2009 included an estimation of the fair value of liabilities associated with any potential earn-out provisions. Subsequent changes in the fair value of earn-out obligations will be recorded in the consolidated statement of income when incurred.
	The fair value of earn-out obligations is based on the present value of the expected future payments to be made to the sellers of the acquired businesses in accordance with the provisions outlined in the respective purchase agreements. In determining fair value, the acquired business’s future performance is estimated using financial projections developed by management for the acquired business and reflects market participant assumptions regarding revenue growth and/or profitability. The expected future payments are estimated on the basis of the earn-out formula and performance targets specified in each purchase agreement compared to the associated financial projections. These payments are then discounted to present value using a risk-adjusted rate that takes into consideration the likelihood that the forecasted earn-out payments will be made.
	Based on the acquisition date and the complexity of the underlying valuation work, certain amounts included in the Company’s Consolidated Financial Statements may be provisional and thus subject to further adjustments within the permitted measurement period, as defined in ASC Topic 805 – Business Combinations (“ASC 805”). For the nine months ended September 30, 2013, several adjustments were made within the permitted measurement period that resulted in a reduction to the aggregate purchase price of the applicable acquisitions of $1,084,000, including $18,000 of cash payments, a reduction of $454,000 in other payables, the assumption of $73,000 of liabilities and the reduction of $721,000 in recorded earn-out payables.
	The following table summarizes the aggregate purchase price allocations made as of the date of each acquisition for current year acquisitions and adjustments made during the measurement period for prior year acquisitions:

	The weighted average useful lives for the acquired amortizable intangible assets are as follows: purchased customer accounts, 15.0 years; and non-compete agreements, 5.0 years.
	Goodwill of $278,553,000, was allocated to the Retail, National Programs and Wholesale Brokerage Divisions in the amounts of $252,753,000, $26,612,000 and ($812,000), respectively. Of the total goodwill of $278,553,000, $24,863,000 is currently deductible for income tax purposes and $251,626,000 is non-deductible. The remaining $2,064,000 relates to the earn-out payables and will not be deductible until it is earned and paid.
	The results of operations for the acquisitions completed during 2013 have been combined with those of the Company since their respective acquisition dates. The total revenues and income (loss) before income taxes from the acquisitions completed through September, 30, 2013, included in the Condensed Consolidated Statement of Income for the three months ended September 30, 2013, were $29,095,000 and ($3,453,000), respectively. The total revenues and income (loss) before income taxes from the acquisitions completed through September, 30, 2013, included in the Condensed Consolidated Statement of Income for the nine months ended September 30, 2013, were $29,723,000 and ($3,311,000), respectively. If the acquisitions had occurred as of the beginning of the period, the Company’s results of operations would be as shown in the following table. These unaudited pro forma results are not necessarily indicative of the actual results of operations that would have occurred had the acquisitions actually been made at the beginning of the respective periods.

	Acquisitions in 2012
	During the nine months ended September 30, 2012, Brown & Brown acquired the assets and assumed certain liabilities of 11 insurance intermediaries, all of the stock of one insurance intermediary and a book of business (customer accounts). The aggregate purchase price of these acquisitions was $620,144,000, including $443,475,000 of cash payments, the issuance of notes payable of $59,000, the issuance of $25,776,000 in other payables, the assumption of $135,779,000 of liabilities and $15,055,000 of recorded earn-out payables. The ‘other payables’ amount includes $22,594,000 that the Company is obligated to pay all shareholders of Arrowhead General Insurance Agency Superholding Corporation (“Arrowhead”) on a pro rata basis for certain pre-merger corporate tax refunds and estimated certain potential future income tax credits that were created by net operating loss carryforwards originating from transaction-related tax benefit items. All of these acquisitions were acquired primarily to expand Brown & Brown’s core businesses and to attract and hire high-quality individuals. Acquisition purchase prices are typically based on a multiple of average annual operating profit earned over a one- to three-year period within a minimum and maximum price range. The recorded purchase price for all acquisitions consummated after January 1, 2009 included an estimation of the fair value of liabilities associated with any potential earn-out provisions.

For acquisitions consummated prior to January 1, 2009, additional consideration paid to sellers as a result of purchase price earn-out provisions are recorded as adjustments to intangible assets when the contingencies are settled. The net additional consideration paid by the Company in 2013 as a result of these adjustments totaled $873,000, all of which was allocated to goodwill. Of the $873,000 net additional consideration paid, $873,000 was issued as an other payable. The net additional consideration paid by the Company in 2012 as a result of these adjustments totaled $2,907,000, all of which was allocated to goodwill. Of the $2,907,000 net additional consideration paid, $2,907,000 was paid in cash.
As of September 30, 2013, the maximum future contingency payments related to all acquisitions totaled $135,122,000, all of which relates to acquisitions consummated subsequent to January 1, 2009.
ASC Topic 805 — Business Combinations is the authoritative guidance requiring an acquirer to recognize 100% of the fair values of acquired assets, including goodwill, and assumed liabilities (with only limited exceptions) upon initially obtaining control of an acquired entity. Additionally, the fair value of contingent consideration arrangements (such as earn-out purchase arrangements) at the acquisition date must be included in the purchase price consideration. As a result, the recorded purchase prices for all acquisitions consummated after January 1, 2009 include an estimation of the fair value of liabilities associated with any potential earn-out provisions. Subsequent changes in these earn-out obligations will be recorded in the consolidated statement of income when incurred. Potential earn-out obligations are typically based upon future earnings of the acquired entities, usually between one and three years.
As of September 30, 2013 and 2012, the fair values of the estimated acquisition earn-out payables were re-evaluated and measured at fair value on a recurring basis using unobservable inputs (Level 3). The resulting additions, payments, and net changes, as well as the interest expense accretion on the estimated acquisition earn-out payables, for the three and nine months ended September 30, 2013 and 2012, were as follows:

	Long-term debt	$	380,000		$	450,000
	In July 2004, the Company completed a private placement of $200.0 million of unsecured senior notes (the “Notes”). The $200.0 million was divided into two series: (1) Series A, which closed on September 15, 2004, for $100.0 million due in 2011 and bore interest at 5.57% per year; and (2) Series B, which closed on July 15, 2004, for $100.0 million due in 2014 and bearing interest at 6.08% per year. Brown & Brown has used the proceeds from the Notes for general corporate purposes, including acquisitions and repayment of existing debt. On September 15, 2011, the $100.0 million of Series A Notes were redeemed on their normal maturity date. As of September 30, 2013 and December 31, 2012, there was an outstanding balance on the Notes of $100.0 million.
	On December 22, 2006, the Company entered into a Master Shelf and Note Purchase Agreement (the “Master Agreement”) with a national insurance company (the “Purchaser”). On September 30, 2009, the Company and the Purchaser amended the Master Agreement to extend the term of the agreement until August 20, 2012. The Purchaser also purchased Notes issued by the Company in 2004. The Master Agreement provides for a $200.0 million private uncommitted “shelf” facility for the issuance of unsecured senior notes over a three-year period, with interest rates that may be fixed or floating and with such maturity dates, not to exceed ten years, as the parties may determine. The Master Agreement includes various covenants, limitations and events of default similar to the Notes issued in 2004. The initial issuance of notes under the Master Agreement occurred on December 22, 2006, through the issuance of $25.0 million in Series C Senior Notes due December 22, 2016, with a fixed interest rate of 5.66% per year. On February 1, 2008, $25.0 million in Series D Senior Notes due January 15, 2015, with a fixed interest rate of 5.37% per year, were issued. On September 15, 2011, and pursuant to a Confirmation of Acceptance, dated January 21, 2011 (the “Confirmation”), in connection with the Master Agreement, $100.0 million in Series E Senior Notes due September 15, 2018, with a fixed interest rate of 4.50% per year, were issued. The Series E Senior Notes were issued for the sole purpose of retiring the Series A Senior Notes. As of September 30, 2013, and December 31, 2012, there was an outstanding debt balance issued under the provisions of the Master Agreement of $150.0 million. The Master Agreement expired on September 30, 2012 and was not extended.
	On October 12, 2012, the Company entered into a Master Note Facility Agreement (the “New Master Agreement”) with another national insurance company (the “New Purchaser”). The New Purchaser also purchased Notes issued by the Company in 2004. The New Master Agreement provides for a $125.0 million private uncommitted “shelf” facility for the issuance of unsecured senior notes over a three-year period, with interest rates that may be fixed or floating and with such maturity dates, not to exceed ten years, as the parties may determine. The New Master Agreement includes various covenants, limitations and events of default similar to the Master Agreement.
	On June 12, 2008, the Company entered into an Amended and Restated Revolving Loan Agreement dated as of June 3, 2008 (the “Prior Loan Agreement”), with a national banking institution, amending and restating the Revolving Loan Agreement dated September 29, 2003, as amended (the “Revolving Agreement”), to, among other things, increase the lending commitment to $50.0 million (subject to potential increases up to $100.0 million) and to extend the maturity date from December 20, 2011, to June 3, 2013. The Revolving Agreement initially provided for a revolving credit facility in the maximum principal amount of $75.0 million. After a series of amendments that provided covenant exceptions for additional notes issued or to be issued under the Master Agreement and relaxed or deleted certain other covenants, the maximum principal amount was reduced to $20.0 million. The Revolving Agreement was amended and restated by the SunTrust Revolver (as defined in the below paragraph).
	On January 9, 2012, the Company entered into: (1) an amended and restated revolving and term loan credit agreement (the “SunTrust Agreement”) with SunTrust Bank (“SunTrust”) that provides for (a) a $100.0 million term loan (the “SunTrust Term Loan”) and (b) a $50.0 million revolving line of credit (the “SunTrust Revolver”) and (2) a $50.0 million promissory note (the “JPM Note”) in favor of JPMorgan Chase Bank, N.A. (“JPMorgan”), pursuant to a letter agreement executed by JP Morgan (together with the JPM Note, (the “JPM Agreement”) that provided for a $50.0 million uncommitted line of credit bridge facility (the “JPM Bridge Facility”). The SunTrust Term Loan, the SunTrust Revolver and the JPM Bridge Facility were each funded on January 9, 2012, and provided the financing for the Arrowhead acquisition. The SunTrust Agreement amended and restated the Prior Loan Agreement.
	The maturity date for the SunTrust Term Loan and the SunTrust Revolver is December 31, 2016, at which time all outstanding principal and unpaid interest will be due. Both the SunTrust Term Loan and the SunTrust Revolver may be increased by up to $50.0 million (bringing the total amount available to $150.0 million for the SunTrust Term Loan and $100.0 million for the SunTrust Revolver). The calculation of interest and fees for the SunTrust Agreement is generally based on the Company’s funded debt-to-EBITDA ratio. Interest is charged at a rate equal to 1.00% to 1.40% above LIBOR or 1.00% below the Base Rate, each as more fully described in the SunTrust Agreement. Fees include an up-front fee, an availability fee of 0.175% to 0.25%, and a letter of credit margin fee of 1.00% to 1.40%. The obligations under the SunTrust Term Loan and SunTrust Revolver are unsecured and the SunTrust Agreement includes various covenants, limitations and events of default that are customary for similar facilities for similar borrowers and that are substantially similar to those contained in the Prior Loan Agreement.
	The maturity date for the JPM Bridge Facility was February 3, 2012, at which time all outstanding principal and unpaid interest would have been due. On January 26, 2012, the Company entered into a term loan agreement (the “JPM Agreement”) with JPMorgan that provided for a $100.0 million term loan (the “JPM Term Loan”). The JPM Term Loan was fully funded on January 26, 2012, and provided the financing to fully repay (1) the JPM Bridge Facility and (2) the SunTrust Revolver. As a result of the January 26, 2012 financing and repayments, the JPM Bridge Facility was terminated and the SunTrust Revolver’s amount outstanding was reduced to zero. At September 30, 2013 and December 31, 2012, there were no borrowings against this SunTrust Revolver.
	The maturity date for the JPM Term Loan is December 31, 2016, at which time all outstanding principal and unpaid interest will be due. Interest is charged at a rate equal to the Alternative Base Rate or 1.00% above the Adjusted LIBOR Rate, each as more fully described in the JPM Agreement. Fees include an up-front fee. The obligations under the JPM Term Loan are unsecured and the JPM Agreement includes various covenants, limitations and events of default that are customary for similar facilities for similar borrowers.
	On July 1, 2013, in conjunction with the Beecher acquisition, the Company entered into: (1) a revolving loan agreement (the “Wells Fargo Agreement”) with Wells Fargo Bank, N.A. (“Wells Fargo”) that provides for a $50.0 million revolving line of credit (the “Wells Fargo Revolver”) and (2) a term loan agreement (the “Bank of America Agreement”) with Bank of America, N.A. (“Bank of America”) that provides for a $30.0 million term loan (the “Bank of America Term Loan”).
	The maturity date for the Wells Fargo Revolver is December 31, 2016, at which time all outstanding principal and unpaid interest will be due. The Wells Fargo Revolver may be increased by up to $50.0 million (bringing the total available to $100.0 million). The calculation of interest and fees for the Wells Fargo Agreement is generally based on the Company’s funded debt-to-EBITDA ratio. Interest is charged at a rate equal to 1.00% to 1.40% above LIBOR or 1.00% below the Base Rate, each as more fully described in the Wells Fargo Agreement. Fees include an up-front fee, an availability fee of 0.175% to 0.25%, and a letter of credit margin fee of 1.00% to 1.40%. The obligations under the Wells Fargo Revolver are unsecured and the Wells Fargo Agreement includes various covenants, limitations and events of default that are customary for similar facilities for similar borrowers. The Wells Fargo Revolver was drawn down in the amount of $30.0 million on July 1, 2013. There were no borrowings against the Wells Fargo Revolver as of September 30, 2013.
	The maturity date for the Bank of America Term Loan is December 31, 2016, at which time all outstanding principal and unpaid interest will be due. The calculation of interest for the Bank of America Agreement is generally based on the Company’s fixed charge coverage ratio. Interest is charged at a rate equal to the Alternative Base Rate or 1.00% to 1.40% above the Adjusted LIBOR Rate, each as more fully described in the Bank of America Agreement. Fees include an up-front fee. Initially, until the Lender receives the Company’s September 30, 2013 quarter end financial statements, the applicable margin for Adjusted LIBOR Rate advances is 1.50%. The obligations under the Bank of America Term Loan are unsecured and the Bank of America Agreement includes various covenants, limitations and events of default that are customary for similar facilities for similar borrowers. The Bank of America Term Loan was funded in the amount of $30.0 million on July 1, 2013. As of September 30, 2013 there was an outstanding balance of $30.0 million.
	The 30-day LIBOR and Adjusted LIBOR Rate as of September 30, 2013 were between 0.18% and 0.19%.
	The Notes, the Master Agreement, the SunTrust Agreement, the JPM Agreement and the Bank of America Agreement all require the Company to maintain certain financial ratios and comply with certain other covenants. The Company was in compliance with all such covenants as of September 30, 2013 and December 31, 2012.
	Acquisition notes payable represent debt incurred to former owners of certain insurance operations acquired by Brown & Brown. These notes and future contingent payments were payable in monthly, quarterly and annual installments through July 2013.

Legal and Regulatory Proceedings	'
	NOTE 9· Legal and Regulatory Proceedings
	The Company is involved in numerous pending or threatened proceedings by or against Brown & Brown, Inc. or one or more of its subsidiaries that arise in the ordinary course of business. The damages that may be claimed against the Company in these various proceedings are in some cases substantial, including in many instances claims for punitive or extraordinary damages. Some of these claims and lawsuits have been resolved, others are in the process of being resolved and others are still in the investigation or discovery phase. The Company will continue to respond appropriately to these claims and lawsuits and to vigorously protect its interests.
	Although the ultimate outcome of such matters cannot be ascertained and liabilities in indeterminate amounts may be imposed on Brown & Brown, Inc. or its subsidiaries, on the basis of present information, availability of insurance and legal advice, it is the opinion of management that the disposition or ultimate determination of such claims will not have a material adverse effect on the Company’s consolidated financial position. However, as (i) one or more of the Company’s insurance companies could take the position that portions of these claims are not covered by the Company’s insurance, (ii) to the extent that payments are made to resolve claims and lawsuits, applicable insurance policy limits are eroded, and (iii) the claims and lawsuits relating to these matters are continuing to develop, it is possible that future results of operations or cash flows for any particular quarterly or annual period could be materially affected by unfavorable resolutions of these matters.
