Summary of Significant Accounting Policies

NOTE 1 Summary of Significant Accounting Policies

Nature of Operations

Brown & Brown, Inc., a Florida corporation, and its subsidiaries (collectively, “Brown & Brown” or the “Company”) is a diversified insurance agency, wholesale brokerage, insurance programs and services organization that markets and sells to its customers insurance products and services, primarily in the property and casualty area. Brown & Brown’s business is divided into four reportable segments: the Retail Division, which provides a broad range of insurance products and services to commercial, public entity, professional and individual customers; the Wholesale Brokerage Division, which markets and sells excess and surplus commercial insurance and reinsurance, primarily through independent agents and brokers; the National Programs Division, which provides professional liability and related package products for certain professionals delivered through nationwide networks of independent agents, and markets targeted products and services designated for specific industries, trade groups, governmental entities and market niches; and the Services Division, which provides insurance-related services, including third-party claims administration and comprehensive medical utilization management services in both the workers’ compensation and all-lines liability arenas, as well as Medicare set-aside services, Social Security disability and Medicare benefits advocacy services, and catastrophe claims adjusting services.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of Brown & Brown, Inc. and its subsidiaries. All significant intercompany account balances and transactions have been eliminated in the Consolidated Financial Statements.

Revenue Recognition

Commission revenues are recognized as of the effective date of the insurance policy or the date on which the policy premium is billed to the customer, whichever is later. Commission revenues related to installment billings at the Company’s subsidiary, Arrowhead General Insurance Agency, Inc. (“Arrowhead”), are recorded on the later of the effective date of the policy or the first installment billing. At those dates, the earnings process has been completed, and Brown & Brown can reliably estimate the impact of policy cancellations for refunds and establish reserves accordingly. The reserve for policy cancellations is based upon historical cancellation experience adjusted for known circumstances. The policy cancellation reserve was $8,010,000 and $7,174,000 at December 31, 2013 and 2012, respectively, and it is periodically evaluated and adjusted as necessary. Subsequent commission adjustments are recognized upon receipt of notification from the insurance companies. Commission revenues are reported net of commissions paid to sub-brokers or co-brokers. Profit-sharing contingent commissions from insurance companies are recognized when determinable, which is when such commissions, or official notification of the amount of such commissions is received. Fee income is recognized as services are rendered.

Use of Estimates

The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as disclosures of contingent assets and liabilities, at the date of the Consolidated Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents principally consist of demand deposits with financial institutions and highly liquid investments with quoted market prices having maturities of three months or less when purchased.

Restricted Cash and Investments, and Premiums, Commissions and Fees Receivable

In its capacity as an insurance agent or broker, Brown & Brown typically collects premiums from insureds and, after deducting its authorized commissions, remits the net premiums to the appropriate insurance company or companies. Accordingly, as reported in the Consolidated Balance Sheets, “premiums” are receivable from insureds. Unremitted net insurance premiums are held in a fiduciary capacity until Brown & Brown disburses them. Brown & Brown invests these unremitted funds only in cash, money market accounts, tax-free variable-rate demand bonds and commercial paper held for a short term. In certain states in which Brown & Brown operates, the use and investment alternatives for these funds are regulated and restricted by various state laws and agencies. These restricted funds are reported as restricted cash and investments on the Consolidated Balance Sheets. The interest income earned on these unremitted funds is reported as investment income in the Consolidated Statements of Income.

In other circumstances, the insurance companies collect the premiums directly from the insureds and remit the applicable commissions to Brown & Brown. Accordingly, as reported in the Consolidated Balance Sheets, “commissions” are receivables from insurance companies. “Fees” are primarily receivables due from customers.

Investments

Certificates of deposit and other securities having maturities of more than three months when purchased are reported at cost and are adjusted for other-than-temporary market value declines.

Fixed Assets

Fixed assets, including leasehold improvements, are carried at cost, less accumulated depreciation and amortization. Expenditures for improvements are capitalized, and expenditures for maintenance and repairs are expensed to operations as incurred. Upon sale or retirement, the cost and related accumulated depreciation and amortization are removed from the accounts and the resulting gain or loss, if any, is reflected in other income. Depreciation has been determined using the straight-line method over the estimated useful lives of the related assets, which range from three to 15 years. Leasehold improvements are amortized on the straight-line method over the shorter of the useful life of the improvement or the term of the related lease.

Goodwill and Amortizable Intangible Assets

The excess of the purchase price of an acquisition over the fair value of the identifiable tangible and amortizable intangible assets is assigned to goodwill. While goodwill is not amortizable, it is subject to assessment at least annually, and more frequently in the presence of certain circumstances, for impairment by application of a fair value-based test. The Company compares the fair value of each reporting unit with its carrying amount to determine if there is potential impairment of goodwill. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the fair value of the goodwill within the reporting unit is less than its carrying value. Fair value is estimated based on multiples of earnings before interest, income taxes, depreciation, amortization and change in estimated acquisition earn-out payables (“EBITDAC”), or on a discounted cash flow basis. Brown & Brown completed its most recent annual assessment as of November 30, 2013 and determined that the fair value of goodwill exceeded the carrying value of such assets. In addition, as of December 31, 2013, there are no accumulated impairment losses.

Amortizable intangible assets are stated at cost, less accumulated amortization, and consist of purchased customer accounts and non-compete agreements. Purchased customer accounts and non-compete agreements are amortized on a straight-line basis over the related estimated lives and contract periods, which range from five to 15 years. Purchased customer accounts primarily consist of records and files that contain information about insurance policies and the related insured parties that are essential to policy renewals.

The carrying value of amortizable intangible assets attributable to each business or asset group comprising Brown & Brown is periodically reviewed by management to determine if there are events or changes in circumstances that would indicate that its carrying amount may not be recoverable. Accordingly, if there are any such changes in circumstances during the year, Brown & Brown assesses the carrying value of its amortizable intangible assets by considering the estimated future undiscounted cash flows generated by the corresponding business or asset group. Any impairment identified through this assessment may require that the carrying value of related amortizable intangible assets be adjusted; however, no impairments were recorded for the years ended December 31, 2013, 2012 and 2011.

Income Taxes

Brown & Brown records income tax expense using the asset-and-liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying values and the income tax bases of Brown & Brown’s assets and liabilities.

Brown & Brown files a consolidated federal income tax return and has elected to file consolidated returns in certain states. Deferred income taxes are provided for in the Consolidated Financial Statements and relate principally to expenses charged to income for financial reporting purposes in one period and deducted for income tax purposes in other periods.

Net Income Per Share

Effective in 2009, the Company adopted new Financial Accounting Standards Board (“FASB”) 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 under the Company’s 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 for the years ended December 31:

Net income per share:
Basic	$	1.50		$	1.28		$	1.15

Diluted	$	1.48		$	1.26		$	1.13

Fair Value of Financial Instruments

The carrying amounts of Brown & Brown’s financial assets and liabilities, including cash and cash equivalents, restricted cash and investments, investments, premiums, commissions and fees receivable, premiums payable to insurance companies, premium deposits and credits due customers and accounts payable, at December 31, 2013 and 2012, approximate fair value because of the short-term maturity of these instruments. The carrying amount of Brown & Brown’s long-term debt approximates fair value at December 31, 2013 and 2012 because the related coupon rate approximates the current market rate.

Stock-Based Compensation

The Company grants stock options and non-vested stock awards to its employees, officers and directors. The Company uses the modified-prospective method to account for share-based payments. Under the modified-prospective method, compensation cost is recognized for all share-based payments granted on or after January 1, 2006 and for all awards granted to employees prior to January 1, 2006 that remained unvested on that date. The Company uses the alternative-transition method to account for the income tax effects of payments made related to stock-based compensation.

The Company uses the Black-Scholes valuation model for valuing all stock options and shares purchased under the Employee Stock Purchase Plan (the “ESPP”). Compensation for non-vested stock awards is measured at fair value on the grant date based upon the number of shares expected to vest. Compensation cost for all awards is recognized in earnings, net of estimated forfeitures, on a straight-line basis over the requisite service period.

NOTE 2 Business Combinations

Acquisitions in 2013

During 2013, Brown & Brown acquired the assets and assumed certain liabilities of ten 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 $519,794,000, including $408,072,000 of cash payments, the issuance of $552,000 in other payables, the assumption of $106,079,000 of liabilities and $5,091,000 of recorded earn-out payables. All of these acquisitions were acquired primarily to expand Brown & Brown’s core businesses and to attract high-quality personnel. 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 Condensed Consolidated Financial Statements may be provisional and thus subject to further adjustments within the permitted measurement period, as defined in Accounting Standards Codification (“ASC”) Topic 805—Business Combinations.

For 2013, several adjustments were made within the permitted measurement period that resulted in a reduction to the aggregate purchase price of the applicable acquisition of $504,000, including $18,000 of cash payments, an increase of $117,000 in other payables, the assumption of $82,000 of liabilities and the reduction of $721,000 in recorded earn-out payables.

The following table summarizes the aggregate purchase price allocation made as of the date of each acquisition for current year acquisitions and adjustment made during the measurement period for prior year acquisitions:

Acquisitions in 2012

During 2012, Brown & Brown acquired the assets and assumed certain liabilities of 19 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 $667,586,000, including $483,933,000 of cash payments, the issuance of notes payable of $59,000, the issuance of $25,439,000 in other payables, the assumption of $136,676,000 of liabilities and $21,479,000 of recorded earn-out payables. The ‘other payables’ amount includes $22,061,000 that the Company is obligated to pay all shareholders of Arrowhead on a pro rata basis for certain pre-merger corporate tax refunds and certain estimated 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 high-quality personnel. 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.

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 in other payables. 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 December 31, 2013, the maximum future contingency payments related to all acquisitions totaled $130,584,000, 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 December 31, 2013, 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 years ended December 31, were as follows:


	For the Year Ended December 31,

Subtotal		40,525			51,569			49,921

Net change in earnings from estimated acquisition earn-out payables:

Of the $43,058,000 estimated acquisition earn-out payables as of December 31, 2013, $6,312,000 was recorded as accounts payable and $36,746,000 was recorded as other non-current liabilities. Of the $52,987,000 in estimated acquisition earn-out payables as of December 31, 2012, $10,164,000 was recorded as accounts payable and $42,823,000 was recorded as other non-current liabilities.

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. The Company 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 December 31, 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 senior unsecured 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 December 31, 2013 and December 31, 2012, there was an outstanding debt balance of $150.0 million attributable to notes issued under the provisions of the Master Agreement. 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 us 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. At December 31, 2013 and December 31, 2012, there were no borrowings against this facility.

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 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 December 31, 2013 and December 31, 2012, there were no borrowings against the 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 acquisition of Beecher Carlson Holdings, Inc., the Company entered into: (1) a revolving loan agreement (the “Wells Fargo Agreement”) with Wells Fargo Bank, N.A. 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 our 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 December 31, 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 our 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 Bank of America received our September 30, 2013 quarter end financial statements, the applicable margin for Adjusted LIBOR Rate advances was 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 December 31, 2013 there was an outstanding balance of $30.0 million.

The 30-day LIBOR and Adjusted LIBOR Rate as of December 31, 2013 were 0.16% and 0.19%, respectively.

The Notes, the Master Agreement, the SunTrust Agreement and the JPM Agreement 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 December 31, 2013 and 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.

Interest paid in 2013, 2012 and 2011 was $16,501,000, $16,090,000 and $15,571,000, respectively.

At December 31, 2013, maturities of long-term debt were $100,000,000 in 2014, $25,000,000 in 2015, $255,000,000 in 2016, $0 in 2017 and $100,000,000 in 2018.

The total amount of unrecognized tax benefits that would affect the Company’s effective tax rate if recognized was $391,000 as of December 31, 2013 and $294,000 as of December 31, 2012. The Company does not expect its unrecognized tax benefits to change significantly over the next 12 months.

As a result of a 2006 Internal Revenue Service (“IRS”) audit, the Company agreed to accrue at each December 31, for tax purposes only, a known amount of profit-sharing contingent commissions represented by the actual amount of profit-sharing contingent commissions received in the first quarter of the related year, with a true-up adjustment to the actual amount received by the end of the following March. Since this method for tax purposes differs from the method used for book purposes, it will result in a current deferred tax asset as of December 31 each year which will reverse by the following March 31 when the related profit-sharing contingent commissions are recognized for financial accounting purposes.

The Company is subject to taxation in the United States and various state jurisdictions. The Company is also subject to taxation in the United Kingdom. In the United States, federal returns for fiscal years 2011 through 2013 remain open and subject to examination by the Internal Revenue Service. The Company files and remits state income taxes in various states where the Company has determined it is required to file state income taxes. The Company’s filings with those states remain open for audit for the fiscal years 2008 through 2013. In the United Kingdom, the Company’s filings remain open for audit for the fiscal years 2012 and 2013.

The Company’s wholly owned subsidiary, Arrowhead General Insurance Agency Superholding Corp, is currently undergoing an Internal Revenue Service review of its federal corporate income tax filings for the tax years ended December 31, 2010, December 31, 2011 and the short period ended January 9, 2012. The Company’s 2008 through 2011 State of Colorado tax returns are currently under audit. In addition the Company has been notified by the State of Oregon regarding audits of all Oregon state tax returns for the period 2009 through 2012. Additionally, the Company has been notified by the State of Michigan regarding a review and audit of state tax returns for the period 2009 through 2011.

Stock-Based Compensation

NOTE 11 Stock-Based Compensation

Performance Stock Plan

In 1996, Brown & Brown adopted and the shareholders approved a performance stock plan, under which until the suspension of the plan in 2010, up to 14,400,000 Performance Stock Plan (“PSP”) shares could be granted to key employees contingent on the employees’ future years of service with Brown & Brown and other performance-based criteria established by the Compensation Committee of the Company’s Board of Directors. Before participants may take full title to Performance Stock, two vesting conditions must be met. Of the grants currently outstanding, specified portions will satisfy the first condition for vesting based on 20% incremental increases in the 20-trading-day average stock price of Brown & Brown’s common stock from the price on the business day prior to date of grant. Performance Stock that has satisfied the first vesting condition is considered “awarded shares.” Awarded shares are included as issued and outstanding common stock shares and are included in the calculation of basic and diluted EPS. Dividends are paid on awarded shares and participants may exercise voting privileges on such shares. Awarded shares satisfy the second condition for vesting on the earlier of a participant’s: (i) 15 years of continuous employment with Brown & Brown from the date shares are granted to the participants (or, in the case of the July 2009 grant to Powell Brown, 20 years); (ii) attainment of age 64 (on a prorated basis corresponding to the number of years since the date of grant); or (iii) death or disability. On April 28, 2010, the PSP was suspended and any remaining authorized but unissued shares, as well as any shares forfeited in the future, will be reserved for issuance under the 2010 Stock Incentive Plan (the “SIP”).

At December 31, 2013, 5,549,882 shares had been granted under the PSP. As of December 31, 2013, 75,435 shares had not met the first condition for vesting, 2,295,852 shares had met the first condition of vesting and had been awarded, and 3,178,595 shares had satisfied both conditions of vesting and had been distributed to participants. Of the shares that have not vested as of December 31, 2013, the initial stock prices ranged from $4.25 to $25.68.

The Company uses a path-dependent lattice model to estimate the fair value of PSP grants on the grant date.

A summary of PSP activity for the years ended December 31, 2013, 2012 and 2011 is as follows:


	Weighted- Average Grant Date Fair Value		Granted Shares			Awarded Shares			Shares Not Yet Awarded

The total fair value of PSP grants that vested during each of the years ended December 31, 2013, 2012 and 2011 was $3,729,000, $23,034,000 and $2,384,000, respectively.

Stock Incentive Plan

On April 28, 2010, the shareholders of Brown & Brown, Inc. approved the Stock Incentive Plan (“SIP”) that provides for the granting of stock options, stock and/or stock appreciation rights to employees and directors contingent on criteria established by the Compensation Committee of the Company’s Board of Directors. The principal purpose of the SIP is to attract, incentivize and retain key employees by offering those persons an opportunity to acquire or increase a direct proprietary interest in the Company’s operations and future success. The SIP includes a sub-plan applicable to Decus Insurance Brokers Limited (“Decus”) which, together with its parent company, Decus Holdings (U.K.) Limited, are the Company’s only foreign subsidiaries. The shares of stock reserved for issuance under the SIP are any shares that are authorized for issuance under the PSP and not already subject to grants under the PSP, and that were outstanding as of April 28, 2010, the date of suspension of the PSP, together with PSP shares and SIP shares forfeited after that date. As of April 28, 2010, 6,046,768 shares were available for issuance under the PSP, which were then transferred to the SIP. To date stock grants to employees under the SIP generally vest in four-to-ten years, subject to the achievement of certain performance criteria by grantees, and the achievement of consolidated EPS growth at certain levels by the Company, over three-to-five-year measurement periods.

In 2010, 187,040 shares were granted under the SIP. This grant was conditioned upon the surrender of 187,040 shares previously granted under the PSP in 2009, which were accordingly treated as forfeited PSP shares. The vesting conditions of this grant were identical to those provided for in connection with the 2009 PSP grant; thus the target stock prices and the periods associated with satisfaction of the first and second conditions of vesting were unchanged. Additionally, grants totaling 5,205 shares were made in 2010 to Decus employees under the SIP sub-plan applicable to Decus.

In 2011, 2,375,892 shares were granted under the SIP. Of this total, 24,670 shares were granted to Decus employees under the SIP sub-plan applicable to Decus. As of December 31, 2012, 37,408 of the granted shares had satisfied the first condition of vesting and had been “awarded”, meaning that dividends are paid on awarded shares and participants may exercise voting privileges on such shares.

In 2012, 814,545 shares were granted under the SIP, primarily related to the Arrowhead acquisition. As of December 31, 2012, no shares had met the first condition for vesting.

In 2013, 3,719,974 shares were granted under the SIP. Of the shares granted in 2013, 891,399 shares will vest upon the grantees’ completion of between three and seven years of service with the Company, and because grantees have the right to vote the shares and receive dividends immediately after the date of grant these shares are considered awarded and outstanding under the two-class method. As of December 31, 2013, no shares had met the first condition for vesting.

Additionally, non-employee members of the Board of Directors received shares annually issued pursuant to the SIP as part of their annual compensation. A total of 36,919 SIP shares were issued to these directors in 2011 and 2012, of which 11,682 were issued in January 2011, 12,627 in January 2012, and 12,610 in December 2012. The shares issued in December 2012 were issued at that earlier time rather than in January 2013 pursuant to action of the Board of Directors. No additional shares were granted or issued to the non-employee members of the Board of Directors in 2013.

At December 31, 2013, 2,207,098 shares were available for future grants, of which 318,134 are reserved for grants with PSP-type vesting conditions.

The Company uses the closing stock price on the day prior to the grant date to determine the fair value of SIP grants and then applies an estimated forfeiture factor to estimate the annual expense. Additionally, the Company uses the path-dependent lattice model to estimate the fair value of grants with PSP-type vesting conditions as of the grant date. SIP shares that satisfied the first vesting condition for PSP-like grants or the established performance criteria are considered awarded shares. Awarded shares are included as issued and outstanding common stock shares and are included in the calculation of basic and diluted EPS.

A summary of SIP activity for the years ended December 31, 2013, 2012 and 2011 is as follows:


	Weighted- Average Grant Date Fair Value		Granted Shares			Awarded Shares			Shares Not Yet Awarded

Employee Stock Purchase Plan

The Company has a shareholder-approved Employee Stock Purchase Plan (“ESPP”) with a total of 12,000,000 authorized shares of which 1,246,838 were available for future subscriptions as of December 31, 2013. Employees of the Company who regularly work more than 20 hours per week are eligible to participate in the ESPP. Participants, through payroll deductions, may allot up to 10% of their compensation, to a maximum of $25,000, to purchase Company stock between August 1^st of each year and the following July 31st (the “Subscription Period”) at a cost of 85% of the lower of the stock price as of the beginning or end of the Subscription Period.

The Company estimates the fair value of an ESPP share option as of the beginning of the Subscription Period as the sum of: (1) 15% of the quoted market price of the Company’s stock on the day prior to the beginning of the Subscription Period, and (2) 85% of the value of a one-year stock option on the Company stock using the Black-Scholes option-pricing model. The estimated fair value of an ESPP share option as of the Subscription Period beginning in August 2013 was $8.36. The fair values of an ESPP share option as of the Subscription Periods beginning in August 2012 and 2011, were $5.84 and $4.27, respectively.

For the ESPP plan years ended July 31, 2013, 2012 and 2011, the Company issued 487,672, 562,748 and 488,052 shares of common stock, respectively. These shares were issued at an aggregate purchase price of $10,456,000, or $21.44 per share, in 2013, $9,302,000, or $16.53 per share, in 2012, and $8,048,000, or $16.49 per share, in 2011.

For the five months ended December 31, 2013, 2012 and 2011 (portions of the 2013-2014, 2012-2013 and 2011-2012 plan years), 222,526, 246,164, and 230,481 shares of common stock (from authorized but unissued shares), respectively, were subscribed to by ESPP participants for proceeds of approximately $5,937,000, $5,278,000 and $3,810,000, respectively.

Incentive Stock Option Plan

On April 21, 2000, Brown & Brown adopted, and the shareholders approved, a qualified incentive stock option plan (the “ISOP”) that provides for the granting of stock options to certain key employees for up to 4,800,000 shares of common stock. On December 31, 2008, the ISOP expired. The objective of the ISOP was to provide additional performance incentives to grow Brown & Brown’s pre-tax income in excess of 15% annually. The options were granted at the most recent trading day’s closing market price and vest over a one-to-10-year period, with a potential acceleration of the vesting period to three-to-six years based upon achievement of certain performance goals. All of the options expire 10 years after the grant date.

The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options on the grant date. The risk-free interest rate is based upon the U.S. Treasury yield curve on the date of grant with a remaining term approximating the expected term of the option granted. The expected term of the options granted is derived from historical data; grantees are divided into two groups based upon expected exercise behavior and are considered separately for valuation purposes. The expected volatility is based upon the historical volatility of the Company’s common stock over the period of time equivalent to the expected term of the options granted. The dividend yield is based upon the Company’s best estimate of future dividend yield.

A summary of stock option activity for the years ended December 31, 2013, 2012 and 2011 is as follows:

The total intrinsic value of options exercised, determined as of the date of exercise, during the years ended December 31, 2013, 2012 and 2011 was $1,558,000, $5,780,000 and $333,000, respectively. The total intrinsic value is calculated as the difference between the exercise price of all underlying awards and the quoted market price of the Company’s stock for all in-the-money stock options at December 31, 2013, 2012 and 2011, respectively.

There are no option shares available for future grant under the ISOP since this plan expired as of December 31, 2008.

Legal Proceedings

The Company records losses for claims in excess of the limits of, or outside the coverage of, applicable insurance at the time and to the extent they are probable and estimable. In accordance with ASC Topic 450—Contingencies, the Company accrues anticipated costs of settlement, damages, losses for liability claims and, under certain conditions, costs of defense, based on historical experience or to the extent specific losses are probable and estimable. Otherwise, the Company expenses these costs as incurred. If the best estimate of a probable loss is a range rather than a specific amount, the Company accrues the amount at the lower end of the range.

The Company’s accruals for legal matters that were probable and estimable were not material at December 31, 2013 and 2012. We continue to assess certain litigation and claims to determine the amounts, if any, that management believes will be paid as a result of such claims and litigation and, therefore, additional losses may be accrued and paid in the future, which could adversely impact the Company’s operating results, cash flows and overall liquidity. The Company maintains third-party insurance policies to provide coverage for certain legal claims, in an effort to mitigate its overall exposure to unanticipated claims or adverse decisions. However, as (i) one or more of the Company’s insurance carriers 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. Based on the A. M. Best ratings of these third-party insurers, management does not believe there is a substantial risk of an insurer’s material nonperformance related to any current insured claims.

On the basis of current information, the availability of insurance and legal advice, in management’s opinion, the Company is not currently involved in any legal proceedings which, individually or in the aggregate, would have a material adverse effect on its financial condition, operations and/or cash flows.

Brown & Brown’s business is divided into four reportable segments: the Retail Division, which provides a broad range of insurance products and services to commercial, public and quasi-public entities, and to professional and individual customers; the National Programs Division, which provides professional liability and related package products for certain professionals delivered through nationwide networks of independent agents, and markets targeted products and services designed for specific industries, trade groups, public and quasi-public entities, and market niches; the Wholesale Brokerage Division, which markets and sells excess and surplus commercial and personal lines insurance, and reinsurance, primarily through independent agents and brokers; and the Services Division, which provides insurance-related services, including third-party claims administration and comprehensive medical utilization management services in both the workers’ compensation and all-lines liability arenas, as well as Medicare set-aside services, Social Security disability and Medicare benefits advocacy services and catastrophe claims adjusting services.

Brown & Brown conducts all of its operations within the United States of America, except for one wholesale brokerage operation based in London, England, and retail operations in Bermuda and the Cayman Islands. These operations earned $12.2 million, $9.7 million and $9.1 million of total revenues for the years ended December 31, 2013, 2012 and 2011, respectively. Long-lived assets held outside of the United States during each of these three years were not material.

The accounting policies of the reportable segments are the same as those described in Note 1. Brown & Brown evaluates the performance of its segments based upon revenues and income before income taxes. Inter-segment revenues are eliminated.

Summarized financial information concerning Brown & Brown’s reportable segments is shown in the following table. The “Other” column includes any income and expenses not allocated to reportable segments and corporate-related items, including the inter-company interest expense charge to the reporting segment.

Subsequent Event	12 Months Ended
Subsequent Event	Dec. 31, 2013
Subsequent Events [Abstract]
Subsequent Event	NOTE 16 Subsequent Event On January 15, 2014, Brown & Brown entered into a merger agreement (the “Agreement”) to acquire The Wright Insurance Group, LLC (“Wright”). Immediately upon the consummation of the merger, Wright’s equity interests will be converted into the rights to receive cash equal, collectively, to $602.5 million. This amount is composed of cash payments of $587.5 million for the Programs Business, $7.5 million for Wright National Flood Insurance Company (“WNFIC”) and $7.5 million for WNFIC statutory surplus. In addition, Wright’s equityholders may receive additional consideration of up to $37.5 million in cash in the event of the closing of certain acquisition transactions by Wright and its affiliates (or, after the closing of the acquisition of Wright, by the Company and its affiliates) prior to July 15, 2015. Under the Agreement, the merger is subject to certain closing conditions including the receipt of required regulatory approvals for the transaction (including the approval of antitrust authorities necessary to complete the acquisition). If the merger is not closed by July 15, 2014 (which may potentially be extended to October 15, 2014 if the only then-outstanding conditions are obtaining regulatory approvals), either party may terminate the agreement.
