Business and Basis of Presentat

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	Business and Basis of Presentation BRP Group, Inc. (“BRP Group” or the “Company”) was incorporated in the state of Delaware on July 1, 2019 . BRP Group was formed for the purpose of completing an initial public offering of its common stock and related transactions in order to carry on the business of Baldwin Risk Partners, LLC (“BRP”) as a publicly-traded entity. On October 28, 2019 , BRP Group completed an initial public offering of its Class A common stock and became the sole managing member of BRP. The financial statements of BRP Group have been presented as a combination of the financial results of BRP Group and BRP as of the earliest period presented as discussed further under Principles of Consolidation section below. BRP Group is a diversified insurance agency and services organization that markets and sells insurance products and services to its customers throughout the U.S., although a significant portion of the Company’s business is concentrated in the southeastern U.S. BRP Group and its subsidiaries operate through four reportable segments (“Operating Groups”), including Middle Market, Specialty, MainStreet, and Medicare, which are discussed in more detail in Note 25 . Initial Public Offering On October 28, 2019 , BRP Group completed an initial public offering (the “Initial Public Offering”) of its Class A common stock, in which it sold 18,859,300 shares, including 2,459,300 shares pursuant to the underwriters’ over-allotment option that subsequently settled on November 26, 2019 . The shares began trading on the Nasdaq Global Select Market (the “Nasdaq”) on October 24, 2019 . The shares were sold at an initial offering price of $14.00 per share for net proceeds of $241.4 million after deducting underwriting discounts and commissions of $17.8 million and net offering expenses of $4.8 million . In connection with the Initial Public Offering, BRP Group and BRP entered into a series of transactions to implement an internal reorganization (the “Reorganization Transactions”), which are described in detail in Note 3 . Principles of Consolidation The consolidated financial statements include the accounts of BRP Group and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. As the sole manager of BRP, BRP Group operates and controls all the business and affairs of BRP, and has the sole voting interest in, and controls the management of, BRP. Accordingly, BRP Group began consolidating BRP in its consolidated financial statements as of the closing date of the Initial Public Offering, resulting in a noncontrolling interest related to the LLC Units held by BRP’s LLC members on its consolidated financial statements. BRP and BRP Group have been under the common control of our Chairman, Lowry Baldwin, before and after the Reorganization Transactions. Prior to the Reorganization Transactions, Mr. Baldwin held a controlling interest in Baldwin Investment Group Holdings, LLC (“BIGH”), which was the controlling owner of BRP through its majority ownership of BRP’s common units. In addition, Mr. Baldwin was the sole shareholder of BRP Group. Upon reorganization, BRP Group became the sole managing member of BRP. Holders of the Class B common stock hold a majority of the voting power of BRP Group and stockholders of a majority of the Class B common stock, including BIGH, executed a Voting Agreement in which they agreed to vote in the same manner as Mr. Baldwin. As a result, Mr. Baldwin continues to control BRP Group subsequent to the Initial Public Offering and Reorganization Transactions. Accordingly, we have accounted for the Reorganization Transactions as a transaction between entities under common control in accordance with Accounting Standards Codification (“ASC”) Topic 805-50, Business Combinations - Related Issues , under which the financial information of BRP Group has been combined with that of BRP as of the earliest period presented. The Company has prepared these consolidated financial statements in accordance with ASC Topic 810, Consolidation (“Topic 810”). Topic 810 requires that if an enterprise is the primary beneficiary of a variable interest entity, the assets, liabilities, and results of operations of the variable interest entity should be included in the consolidated financial statements of the enterprise. The Company has recognized certain entities as variable interest entities of which the Company is the primary beneficiary and has included the accounts of these entities in the consolidated financial statements. Refer to Note 5 for additional information regarding the Company’s variable interest entities. Topic 810 also requires that the equity of a noncontrolling interest shall be reported in the consolidated balance sheets within total equity of the Company. Certain redeemable noncontrolling interests are reported in the consolidated balance sheets as mezzanine equity. Topic 810 also requires revenues, expenses, gains, losses, net income or loss, and other comprehensive income or loss to be reported in the consolidated financial statements at consolidated amounts, which include amounts attributable to the owners of the parent and the noncontrolling interests. Refer to the Redeemable Noncontrolling Interest and Noncontrolling Interest sections of Note 2 for additional information. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Significant estimates underlying the accompanying consolidated financial statements include the application of guidance for revenue recognition, including determination of allowances for estimated policy cancellations, business combinations and purchase price allocation, impairment of long-lived assets including goodwill, and valuation of the Tax Receivable Agreement liability, advisor incentive liabilities and share-based compensation. Changes in Presentation Certain prior year amounts have been reclassified to conform to current year presentation. Recent Accounting Pronouncements As an emerging growth company, the Jumpstart Our Business Startups (“JOBS”) Act permits the Company an extended transition period for complying with new or revised accounting standards affecting public companies. The Company has elected to use this extended transition period and adopt certain new accounting standards on the private company timeline, which means that the Company’s financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards on a non-delayed basis. The Company has elected the extended transition period for the adoption of the Accounting Standards Updates (“ASU”) below, except those where early adoption was both permitted and elected. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases . ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. The FASB has subsequently issued several additional ASUs related to leases, which improved upon, and provided transition relief for, the guidance issued in ASU 2016-02 and extended the adoption date for nonpublic business entities. This guidance is effective for the fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the full effect that the adoption of this standard will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements (“ASU 2016-13”), which amends the guidance for recognizing credit losses on financial instruments measured at amortized cost. ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The FASB has subsequently issued several additional ASUs related to credit losses, which improved upon, and provided transition relief for, the guidance issued in ASU 2016-13 and extended the adoption date for nonpublic business entities. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the full effect that the adoption of this standard will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 provides guidance on the classification of contingent consideration payments made after a business combination and other cash receipts and payments. The Company adopted ASU 2016-15 effective January 1, 2019 and has applied the guidance retrospectively for its consolidated statement of cash flows for the years ended December 31, 2019 and 2018. The Company applied the guidance in ASU 2016-15 to its payment of contingent consideration liabilities related to business combinations and the payment of debt extinguishment costs, which impacted the presentation of the cash flows, but did not otherwise impact on the Company’s results of operations or financial condition. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that the statement of cash flows explain the changes during the period of cash and cash equivalents inclusive of amounts categorized as restricted cash. The Company adopted ASU 2016-18 effective January 1, 2019. With the adoption of ASU 2016-18, the statements of cash flows detail the change in the balance of cash and cash equivalents and restricted cash. The adoption of this guidance did not have any effect on cash flows for the year ended December 31, 2018. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which amends the guidance on goodwill. Under ASU 2017-04, goodwill impairment is measured as the amount by which a reporting unit’s carrying value exceeds its fair value, while not exceeding the carrying value of goodwill. ASU 2017-04 eliminates existing guidance that requires an entity to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all its assets and liabilities as if that reporting unit had been acquired in a business combination. The Company early adopted this guidance for impairment tests effective January 1, 2019 and it did not have any impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) (“Topic 820”): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which modifies the disclosure requirements related to fair value measurement, by removing certain disclosure requirements related to the fair value hierarchy, modifying existing disclosure requirements related to measurement uncertainty and adding new disclosure requirements, such as disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in ASU 2018-13 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), which provides guidance for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company early adopted ASU 2018-15 for implementation costs related to its service contracts effective January 1, 2019 and applied it prospectively for all cloud computing arrangement implementation costs incurred on or after the effective date. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), as part of its Simplification Initiative to reduce the cost and complexity in accounting for income taxes. ASU 2019-12 removes certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. The guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company early adopted ASU 2019-12 in the fourth quarter of 2019. The adoption did not have a material impact on our consolidated financial statements.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Revenue Recognition Effective January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”) and all related amendments that established Topic 606. The Company adopted these standards by recognizing the cumulative effect as an adjustment to opening retained earnings at January 1, 2018 under the modified retrospective method for contracts not completed as of the day of adoption. The Company elected the practical expedient to evaluate only contracts not completed at the date of initial application. The cumulative impact of adopting Topic 606 on January 1, 2018 was an increase in retained earnings and noncontrolling interest within members’ equity (deficit) totaling $6.8 million . The Company earns commission revenue by facilitating the arrangement between Insurance Company Partners and individuals or businesses by providing insurance placement services to insureds (“Clients”) with Insurance Company Partners. Commission revenues are usually a percentage of the premium paid by Clients and generally depend upon the type of insurance, the Insurance Company Partner and the nature of the services provided. In some limited cases, the Company shares commissions with other agents or brokers who have acted jointly with the Company in a transaction. The Company controls the fulfillment of the performance obligation and its relationship with its Insurance Company Partners and the outside agents. Commissions shared with downstream agents or brokers are recorded in commission, employee compensation and benefits expense in the consolidated statements of comprehensive income (loss). Commissions are earned at a point in time upon the effective date of bound insurance coverage as no performance obligation exists after coverage is bound. Commission revenue is recorded net of allowances for estimated policy cancellations, which are determined based on an evaluation of historical and current cancellation data. The Company earns service fee revenue in its Middle Market segment by receiving negotiated fees in lieu of a commission and consulting revenue from services other than securing insurance coverage. Service fee and consulting revenues from certain agreements are recognized over time depending on when the services within the contract are satisfied and when the Company has transferred control of the related services to the customer. Commissions and fees for brokerage services may be invoiced near the effective date of the underlying policy or over the term of the arrangement in installments during the policy period. However, regardless of the payment terms, commissions are recognized at a point in time upon the effective date of bound insurance coverage, as no performance obligation exists after coverage is bound. The Company may receive a profit-sharing commission from an Insurance Company Partner, which is based primarily on underwriting results, but may also contain considerations for volume, growth, loss performance, or retention. Profit-sharing commissions represent a form of variable consideration, which includes additional commissions over base commissions received from Insurance Company Partners. Profit-sharing commissions associated with relatively predictable measures are estimated with a constraint applied and recognized at a point in time. The profit-sharing commissions are recorded as the underlying policies that contribute to the achievement of the metric are placed with any adjustments recognized when payments are received or as additional information that affects the estimate becomes available. Profit-sharing commissions associated with loss performance are uncertain, and therefore, are subject to significant reversal through catastrophic loss season and as loss data remains subject to material change. The constraint is relieved when management estimates revenue that is not subject to significant reversal, which often coincides with the earlier of written notice from the Insurance Company Partner that the target has been achieved, or cash collection. Year-end amounts incorporate estimates based on confirmation from Insurance Company Partners after calculation of potential loss ratios that are impacted by catastrophic losses. The consolidated financial statements include estimates based on constraints and incorporates information received from Insurance Company Partners, and where still subject to significant changes in estimates due to loss ratios and external factors that are outside of the Company’s control, a full constraint is applied. The Company pays an incremental amount of compensation in the form of producer commissions on new business. These incremental costs are capitalized as deferred commission expense and amortized over five years, which represents management’s estimate of the average period over which a Client maintains its initial coverage relationship with the original Insurance Company Partner. The Company has concluded that this period is consistent with the transfer to the customer of the services to which the asset relates. Due to the relatively short time period between the information gathering phase and binding insurance coverage, the Company has determined that costs to fulfill contracts are not significant. Therefore, costs to fulfill a contract are expensed as incurred. The Company earns policy fee revenue for acting in its capacity as a managing general agent (“MGA”) on behalf of the Insurance Company Partner and fulfilling certain services including delivery of policy documents, processing payments and other administrative functions during the term of the insurance policy. Policy fee revenue is deferred and recognized over the life of the policy. These deferred amounts are recognized as contract liabilities, which is included as a component of accrued expenses and other current liabilities on the consolidated balance sheets. The Company earns installment fee revenue related to policy premiums paid on an installment basis for payment processing services performed on behalf of the Insurance Company Partner. The Company recognizes installment fee revenue in the period the services are performed. Cash Equivalents The Company considers all highly liquid short-term instruments with original maturities of three months or less to be cash equivalents. Restricted Cash Restricted cash includes amounts that are legally restricted as to use or withdrawal. Restricted cash represents cash collected from customers that is payable to insurance companies and for which segregation of this cash is required by contract with the relevant insurance company providing coverage or by law within the state. The Company holds restricted cash specifically in its role as an MGA. Premiums, Commissions and Fees Receivable, Net In its capacity as an insurance agent or broker, the Company typically collects premiums from Clients, and after deducting its authorized commissions, remits the net premiums to the appropriate Insurance Company Partners. Accordingly, premiums receivable reflect these amounts due from Clients. In other circumstances, the Insurance Company Partners collect the premiums directly from Clients and remit the applicable commissions to the Company. Accordingly, commissions receivable reflect these amounts due from Insurance Company Partners. Fees receivable primarily represent amounts due from Clients of the Company’s services division. Premiums, commissions and fees receivable are reported net of allowances for estimated policy cancellations and doubtful accounts. The allowance for estimated policy cancellations was $2.2 million and $250,000 at December 31, 2019 and 2018 , respectively, which represents a reserve for future reversals in commission and fee revenues related to the potential cancellation of client insurance policies that were in force as of each year end. The allowance for estimated policy cancellations is established through a charge to revenues. The allowance for estimated policy cancellations is offset in part by a producer commissions chargeback of $1.2 million at December 31, 2019 . The producer commissions chargeback is established through a charge to producer commissions expense and is netted against producer commissions payable on the balance sheets. The allowance for doubtful accounts was $50,000 and $40,000 at December 31, 2019 and 2018 , respectively. The allowance for doubtful accounts is based on management’s estimate of the amount of receivables that will actually be collected. Accounts are charged to the allowance as they are deemed uncollectible based upon a periodic review of the accounts. Property and Equipment, Net Property and equipment is stated at cost. For financial reporting purposes, depreciation of property and equipment is calculated using the straight-line method over the estimated useful lives of the assets as follows: Years Building 39 Leasehold improvements 3 - 10 Furniture 5 - 7 Office and computer equipment 3 - 7 Vehicle 5 Website development 7 Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful life or the reasonably assured lease term at inception of the lease. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts. The difference between the net book value of the assets and proceeds from disposal is recognized as a gain or loss on disposal, which is included in other income (expense), net in the consolidated statements of comprehensive income (loss). Routine maintenance and repairs are charged to expense as incurred, while costs of improvements and renewals are capitalized. Property and equipment is evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. An asset is considered to be impaired when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposition does not exceed its carrying amount. The amount of the impairment loss, if any, is measured as the amount by which the carrying value of the asset exceeds its fair value. Intangible Assets, Net and Goodwill The majority of the Company’s intangible assets are acquired in connection with strategic acquisitions made by the Company (“Partnerships”). Intangible assets identified in a Partnership are recorded at fair value on the acquisition date. The excess of the purchase price in a business combination over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed is assigned to goodwill. Intangible assets are stated at cost, less accumulated amortization, and consist of purchased customer accounts, carrier relationships, software and trade names acquired in connection with business combinations. Purchased customer accounts, carrier relationships and trade names are being amortized based on a pattern of economic benefit over an estimated life of five to twenty years. Purchased customer accounts primarily consist of records and files that contain information about insurance policies and the related Clients that are essential to policy renewals. Carrier relationships consist of relationships with Insurance Company Partners that were not previously established. Trade names consist of acquired business names with potential customer base recognition. Intangible assets also include software, which is amortized on the straight-line basis over an estimated useful life of three to five years. We review our definite-lived intangible assets and other long-lived assets for impairment whenever an event occurs that indicates the carrying amount of an asset may not be recoverable. No impairment was recorded for the years ended December 31, 2019 and 2018 . Goodwill is subject to an impairment assessment on an annual basis or whenever indicators of impairment are present. The Company performs a qualitative assessment to determine whether a quantitative impairment test is necessary. In a quantitative assessment, 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 carrying value of a reporting unit is greater than the fair value, an impairment charge is recorded for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the amount of goodwill of the reporting unit. Deferred Financing Costs, Net Deferred financing costs consist of origination fees and debt issuance costs related to obtaining credit facilities. The Company has recorded these costs as an asset on the consolidated balance sheets in accordance with ASC Topic 835-30, Interest. Deferred financing costs are included in other assets on the consolidated balance sheets. Deferred financing costs were approximately $1.8 million and $861,000 , net of accumulated amortization of approximately $470,000 and $270,000 at December 31, 2019 and 2018 , respectively. Such costs are amortized using the effective interest method over the terms of the respective debt. Amortization of deferred financing costs was approximately $1.3 million and $118,000 for the years ended December 31, 2019 and 2018 , respectively, and is included in interest expense, net in the accompanying consolidated statements of comprehensive income (loss). Contingent Earnout Liabilities The Company accounts for contingent consideration relating to business combinations as either contingently returnable consideration or a contingent earnout liability and a decrease (increase) to goodwill at the date of the acquisition and continually remeasures the asset or liability at each balance sheet date by recording changes in the fair value through change in fair value of contingent consideration in the consolidated statements of comprehensive income (loss). The ultimate settlement of contingently returnable consideration and contingent earnout liabilities relating to business combinations may be for amounts that are materially different from the amounts initially recorded and may cause volatility in the Company’s results of operations. The Company accounts for contingent consideration relating to asset acquisitions as a contingent earnout liability and an increase to the cost of the acquired assets on a relative fair value basis at the date of the acquisition. Once recognized, the contingent earnout liability is not derecognized until the contingency is resolved and the consideration is issued or becomes issuable. If the amount initially recognized as a liability exceeds the fair value of the contingent consideration issued or issuable, the entity recognizes that amount as a reduction of the cost of the asset acquisition. The ultimate settlement of contingent earnout liabilities relating to asset acquisitions may be for amounts that are materially different from the amounts initially recorded. The Company determines the fair value of contingently returnable consideration and contingent earnout liabilities based on future cash flow projections under various potential scenarios and weighs the probability of these outcomes as discussed further in Note 23 . Advisor Incentive Liabilities During the last several years, the Company entered into advisor incentive agreements with several of its producers (“Risk Advisors”) to incentivize them to stay with the Company, grow their book of business, and earn the role of partner as a member of the Company. The incentive rights had a deposit buy-in requirement payable in the form of payroll withholding or other cash payments for which the Company recorded an advisor incentive liability. The incentive rights could be converted to LLC Units after the achievement of certain milestones, subject to approval at the discretion of management. The units were convertible for a proportionate share of the fair value of BRP or one of its subsidiaries. The redemption price was not affected by changes in the units’ fair value. An increase in fair value of units would reduce the number of units issued to satisfy the obligation. The agreement does not limit the amount the Company could be required to pay or the number of units required to be issued. The Company accounts for the advisor incentive awards as liability-classified share-based payment awards under ASC 718, Compensation - Stock Compensation (“Topic 718”). Risk Advisors were deemed probable of meeting the performance condition after having achieved the first milestone related to their advisor incentive agreements. Thereafter, the Company estimated the fair value of the grants and recorded compensation expense and an advisor incentive liability each reporting period through the settlement date. Advisor incentive liabilities are included in other liabilities on the consolidated balance sheet and compensation expense for advisor incentive liabilities is included in commissions, employee compensation and benefits in the consolidated statements of comprehensive income (loss). Advisor incentive liabilities were classified as non-current liabilities as they were not expected to be settled in the near term at December 31, 2019 and 2018. Participation Unit Ownership Plan Liabilities During 2016, the Company established the Participation Unit Ownership Plan (the “Participation Plan”), which offered certain Colleagues additional incentives to promote success. The Participation Plan permitted the grant of up to 100,000 participation units, to be settled in cash only. Participation units vested on the fifth anniversary of the date of the grant unless a qualifying event occurs, as outlined in the Participation Plan agreement. Refer to Note 13 for further discussion of the Company’s participation plan liabilities, which were settled in connection with the Reorganization Transactions. The Company accounts for the issuance of participation units in accordance with ASC Topic 710, Compensation , which requires these units to be treated as liabilities on the consolidated balance sheets. At the grant date and at the end of each subsequent reporting period, the Company estimates the ultimate payout of the participation units. The Company records compensation expense and liability based on this estimated payout and for the portion of the vesting period that has been completed. Participation unit ownership plan liabilities are included in other liabilities on the consolidated balance sheet and Compensation expense for participation units is included in commissions, employee compensation and benefits expense in the consolidated statements of comprehensive income (loss). Redeemable Noncontrolling Interest ASC Topic 480, Distinguishing Liabilities from Equity (“Topic 480”) , requires noncontrolling interests that are redeemable for cash or other assets to be classified outside of permanent equity if they are redeemable (i) at a fixed or determinable price on a fixed or determinable date, (ii) at the option of the holder, or (iii) upon the occurrence of an event that is not solely within the control of the issuer. Prior to the Reorganization Transactions, the equity securities of certain of the Company’s noncontrolling interests contained an embedded put feature that was redeemable at the election of the interest holder. The Company had no control over whether the put option was exercised, and therefore, redemption was outside the Company’s control. As such, these equity securities were recorded as redeemable noncontrolling interests, which were classified in mezzanine equity on the Company’s consolidated balance sheets at December 31, 2018. Redeemable noncontrolling interests are reported at estimated redemption value measured as the greater of estimated fair value at the end of each reporting period or the historical cost basis of the redeemable noncontrolling interest adjusted for cumulative earnings or loss allocations. The resulting increases or decreases to redemption value, if applicable, are recognized as adjustments to retained earnings. The accounts of the following joint ventures have been consolidated into the Company’s consolidated financial statements since their respective inceptions until the Reorganization Transactions. The noncontrolling ownership interests in the Company’s subsidiaries described below are presented as redeemable noncontrolling interest in the consolidated financial statements prior to the Reorganization Transactions. • In 2018, BRP Black Insurance, LLC (“Black”) was formed in order to acquire substantially all the assets and liabilities of Black Insurance and Financial Services, LLC from Christopher R. Black (“Chris Black”). Chris Black had a 40% ownership interest in Black prior to the Reorganization Transactions. • In 2018, BRP Insurance Intermediary Holdings, LLC (“BIH”) was formed in order to acquire 60% of the membership interests of AB Risk Specialist, LLC (“ABRS”), which owned a 100% membership interest in KB Risk Solutions, LLC (“KBRS”), from AB Risk Holdco, Inc. (“AB Holdco”). Additionally, immediately following BIH’s acquisition of the membership interests of ABRS, Emanuel Lauria was issued a 33.3% membership interest in KBRS. AB Holdco had a 40% ownership interest in ABRS prior to the Reorganization Transactions. • In 2018, Baldwin Krystyn Sherman Partners, LLC (“BKS”) acquired substantially all the assets and liabilities of Montoya Property & Casualty Insurance from Montoya and Associates, LLC (“Montoya & Associates”). Montoya & Associates had a 1.5% ownership interest in BKS prior to the Reorganization Transactions. • In 2019, BIH acquired 70% of the membership interests of Millennial Specialty Insurance, LLC from Millennial Specialty Holdco, LLC (“MSH”). MSH had a 30% ownership interest in Millennial Specialty Insurance, LLC prior to the Reorganization Transactions. • In 2019, BKS Financial Investments, LLC was formed to acquire substantially all the assets and liabilities of Fiduciary Partners Investment Consulting, LLC and BKS acquired substantially all the assets and liabilities of Fiduciary Partners Retirement Group, Inc. (“FPRG”) and Fiduciary Partners Group, LLC. FPRG had a 0.3% ownership interest in BKS prior to the Reorganization Transactions. • In 2019, BRP Foundation, LLC (“Foundation”) was formed in order to acquire substantially all the assets and liabilities of Foundation Insurance of Florida, LLC from its members (“Foundation Members”). The Foundation Members had a 20% ownership interest in Foundation prior to the Reorganization Transactions. In conjunction with the Reorganization Transactions as discussed in Note 3 , the Company executed its call rights for the majority of the redeemable noncontrolling ownership interests, which were converted into permanent equity through the issuance of Class B common stock and LLC Units. Refer to Note 15 for additional discussion of redeemable noncontrolling interest. Redeemable Members ’ Capital Topic 480 requires common units that are redeemable for cash or other assets to be classified outside of permanent equity if they are redeemable (i) at a fixed or determinable price on a fixed or determinable date, (ii) at the option of the holder, or (iii) upon the occurrence of an event that is not solely within the control of the issuer. Prior to the Reorganization Transactions, the Voting Common Units of two minority holders contained certain put and call rights in conjunction with termination at the greater of fair value or a floor, as defined in the BRP’s amended and restated limited liability operating agreement (the “Operating Agreement”). The Company had no control over whether the put option was exercised, and therefore, redemption was outside the Company’s control. As such, these equity securities were recorded as redeemable members’ capital, which were classified in mezzanine equity on the Company’s consolidated balance sheets. In conjunction with the Reorganization Transactions as discussed in Note 3 , the Company executed its call rights for redeemable members’ capital ownership interests, which were converted into permanent equity through the issuance of Class B common stock and LLC Units. Refer to Note 15 for additional discussion of redeemable members’ capital. Noncontrolling Interest Noncontrolling interests are reported at historical cost basis adjusted for cumulative earnings or loss allocations and classified as a component of stockholders’/members’ equity (deficit) on the consolidated balance sheets. Noncontrolling interest as presented herein as of and for the year ended December 31, 2018 consists of the noncontrolling interest holdings of BRP. Noncontrolling interest as presented as of and for the year ended December 31, 2019 consists of the noncontrolling interest holdings of BRP Group subsequent to the Reorganization Transactions. The controlling interest holdings of BRP for the period from January 1, 2019 through October 27, 2019 have been reclassified to noncontrolling interest holdings of BRP Group for presentation of activity for the year ended December 31, 2019. Income Taxes BRP has been, and will continue to be, treated as a partnership for U.S. federal, state and local income tax purposes. As a partnership, BRP’s taxable income or loss is included in the taxable income of its members. Accordingly, no income tax expense was recorded for federal and state and local jurisdictions for periods prior to the Initial Public Offering. BRP Group is a taxable entity and in connection with the Initial Public Offering and the Reorganization Transactions completed on October 28, 2019 , the Company became a taxable entity. In addition, BRP Colleague Inc., a subsidiary of BRP Group, was formed as a C Corporation during 2017 and is a taxable entity. The Company accounts for income taxes pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. The Company and its subsidiaries follow ASC Topic 740, Income Taxes . A component of this standard prescribes a recognition and measurement threshold of uncertain tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. Management has evaluated the Company’s tax positions and concluded that the Company has taken no uncertain tax positions that require adjustment to the financial statements to comply with the provisions of this guidance. The Company does not expect any of its tax positions to change significantly in the near term. Tax Receivable Agreement The Company’s purchase of BRP’s LLC Units concurrent with the Initial Public Offering, and the future exchanges of LLC Units from BRP’s LLC Members and the corresponding number of shares of Class B common stock for shares of Class A common stock, is expected to result in increases in its share of the tax basis of the tangible and intangible assets of BRP, which will increase the tax depreciation and amortization deductions that otherwise would not have been available to BRP Group. These increases in tax basis and tax depreciation and amortization deductions are expected to reduce the amount of cash taxes that BRP Group would otherwise be required to pay in the future. BRP Group has entered into a Tax Receivable Agreement, with the other members of BRP that requires it to pay them 85% of the amount of cash savings, if any, in U.S. federal, state, and local income tax that BRP Group actually realizes (or, under certain circumstances, is deemed to realize) as a result of the increases in tax basis in connection with exchanges by the recipients described above and certain other tax benefits attributable to payments under the Tax Receivable Agreement. Share-Based Compensation Share-based payments to employees and non-employee directors are measured based on the estimated grant-date fair value. The grant-date fair value of restricted stock awards is equal to the market value of BRP Group’s Class A common stock on the date of grant. The Company recognizes share-based compensation expense over the requisite service period for awards expected to ultimately vest. The Company recognizes forfeitures as they occur. Fair Value of Financial Instruments The carrying values of the Company’s financial assets and liabilities, including cash and cash equivalents, premiums, commissions and fees receivable, premiums payable to insurance companies and accrued expenses and other current liabilities, approximate their fair values because of the short maturity and liquidity of those instruments. Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents. The Company manages this risk using high credit worthy financial institutions. Interest-bearing accounts and noninterest-bearing accounts are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 . Deposits exceed amounts insured by the FDIC. The Company has not experienced any losses from its deposits. For the year ended December 31, 2019 , two Insurance Company Partners accounted for approximately 14% and 10% of the Company’s total core commissions.

Reorganization Transactions [Abstract]
Reorganization Transactions	Reorganization Transactions In connection with the Initial Public Offering, BRP Group and BRP entered into the Reorganization Transactions as follows: • BRP amended and restated its amended and restated limited liability company agreement (the “Amended LLC Agreement”) to, among other things, appoint BRP Group as the sole managing member of BRP and to modify BRP’s capital structure to reclassify all the equity interests into a single class of LLC units (the “LLC Units”); • as sole managing member of BRP, BRP Group consolidates the financial results of BRP and a portion of the net income is allocated to the noncontrolling interest to reflect the entitlement of the owners of BRP’s outstanding equity interests (“BRP’s LLC Members”) to a portion of BRP’s net income; • through a series of internal transactions, BRP issued LLC Units to equity holders of companies it has acquired (its “Partners”) (other than certain joint ventures) in exchange for all the equity interests in such Partners not held by BRP prior to such exchange; • BRP Group’s certificate of incorporation authorized the issuance of two classes of common stock including Class A common stock and Class B common stock, each of which entitles its holder to one vote per share on all matters submitted to a vote of the stockholders; • each of the owners of BRP LLC Units prior to the Initial Public Offering (the “Pre-IPO LLC Members”) was issued shares of BRP Group’s Class B common stock in an amount equal to the number of LLC Units held by each such member following the reclassification of the equity interest into LLC Units; • under the Amended LLC Agreement, BRP’s LLC Members have the right to require BRP to redeem all or a portion of their LLC Units for, at BRP Group’s election, newly-issued shares of Class A common stock on a one-for-one basis or a cash payment; • BRP Group and BRP’s members entered into the Stockholders Agreement, which provides that approval by BRP’s LLC Members is required for certain corporate actions; • BRP Group used the net proceeds from the Initial Public Offering to acquire 14,000,000 newly-issued LLC Units from Baldwin Risk Partners, LLC, 1,800,000 LLC Units from Lowry Baldwin, the Company’s Chairman, and 600,000 LLC Units from The Villages Invesco, LLC (“Villages Invesco”), one of our significant shareholders, at a purchase price per LLC Unit equal to the initial public offering price of Class A common stock after underwriting discounts and commissions; and • BRP Group entered into the Tax Receivable Agreement, which provides for payment by BRP Group to BRP’s LLC Members of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that BRP Group actually realizes. In connection with the Initial Public Offering, BRP Group issued one share of Class B common stock to Pre-IPO LLC Members for each LLC Unit held by such BRP LLC Members. BRP Group intends to issue one share of Class B common stock for each LLC Unit that BRP issues. The Class B common stock can be exchanged (together with a corresponding number of LLC Units) for shares of Class A common stock on a one-for-one basis, subject to certain restrictions, and the shares of Class B common stock will be canceled on a one-for-one basis with the redemption or exchange. As a result, the number of shares of Class B common stock will continue to increase with each Partnership in which we issue a noncontrolling interest, which will dilute the ownership interest of the Company’s Class A common stockholders. In conjunction with the Reorganization Transactions, BRP issued LLC Units to equity holders of its Partners (other than certain joint ventures) in exchange for all of the equity interests in such Partners not held by BRP prior to such exchange. In each of the Partner operating agreements, BRP held a right to acquire the equity interests of the Partners of the underlying subsidiaries. Acquisition of the Partners’ equity interests was recorded in accordance with Topic 810. Previously redeemable Voting Common Units were replaced with LLC Units that do not contain a similar redemption provision while certain redeemable noncontrolling interests remain redeemable subsequent to the conversion. The following is a description of the transactions to convert the Company’s obligations related to its advisor incentive agreements and participation unit ownership plan to shares of Class A common stock. • The Company exchanged $2.2 million of its obligation related to advisor incentive liabilities for 204,807 restricted shares of Class A common stock issued under the Company’s Omnibus Incentive Plan. The Company established stockholder notes receivable of $452,000 for the remaining deposit buy-in amounts due from the advisors and relieved advisor incentive liabilities for $2.2 million with an offset to additional paid-in capital of $2.6 million . • The Company’s obligation under the participation unit ownership plan of $311,000 was exchanged for 22,243 restricted shares of Class A common stock issued under the Company’s Omnibus Incentive Plan, which resulted in an offset to additional paid-in capital of $311,000 . The following is a description of the transactions to convert LLC Units held by each of the Pre-IPO LLC Members to shares of Class B common stock in an amount equal to the number of LLC Units held by each such member following the reclassification of the equity interest into LLC Units. • The Company executed its call rights for the Voting Common Units of two minority founders, a component of redeemable members’ capital prior to the reorganization, which were converted into permanent equity consisting of 5,701,107 shares of Class B common stock and LLC Units. • The Company executed its call rights for the Villages Voting Common Units, a component of redeemable members’ capital prior to the reorganization, which were converted into permanent equity consisting of 3,077,559 shares of Class B common stock and LLC Units. • The Company executed its call rights for the Rollover Members’ Units, which comprised redeemable noncontrolling interest prior to the reorganization, which were converted into 9,615,911 shares of Class B common stock and LLC Units. • Voting Common Units held by the majority founder, which comprised members’ equity prior to the reorganization, were converted into 18,933,907 shares of Class B common stock and LLC Units. • The Non-Voting Common Units, which comprised noncontrolling interest prior to the reorganization, were converted into permanent equity consisting of 232,596 shares of Class B common stock and LLC Units. • Management Incentive Units were converted to 5,627,155 restricted shares of Class B common stock and LLC Units.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Business Combinations The Company completed four business combinations for an aggregate purchase price of $173.5 million during the year ended December 31, 2019 . In accordance with ASC Topic 805, Business Combinations (“Topic 805”), total consideration was first allocated to the fair value of assets acquired, including liabilities assumed, with the excess being recorded as goodwill. For financial statement purposes, goodwill is not amortized but rather is evaluated for impairment at least annually or more frequently if an event occurs that indicates goodwill may be impaired. Goodwill is deductible for tax purposes and will be amortized over a period of fifteen years . The intangible assets acquired in connection with business combinations during the year ended December 31, 2019 have an estimated weighted-average life as follows: Weighted-Average Life Purchased customer accounts 16.8 years Software 5 years Carrier relationships 20 years Trade names 5 years The recorded purchase price for certain business combinations includes an estimation of the fair value of continent consideration obligations associated with potential earnout provisions, which are generally based on revenue or earnings before income taxes, depreciation and amortization (“EBITDA”). The contingent earnout consideration identified in the tables below are measured at fair value within Level 3 of the fair value hierarchy as discussed further in Note 23 . Any subsequent changes in the fair value of contingent earnout liabilities will be recorded in the consolidated statements of comprehensive income (loss) when incurred. The recorded purchase price for certain business combinations also includes an estimation of the fair value of noncontrolling interests, which are calculated based on a valuation of the entity with the relevant percentage applied.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities Topic 810 requires a reporting entity to consolidate a variable interest entity (“VIE”) when the reporting entity has a variable interest or combination of variable interests that provide the entity with a controlling financial interest in the VIE. The Company continually assesses whether it has a controlling financial interest in each of its VIEs to determine if it is the primary beneficiary of the VIE and should, therefore, consolidate each of the VIEs. A reporting entity is considered to have a controlling financial interest in a VIE if it has (i) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb the losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company determined that it is the primary beneficiary of its VIEs, which, at December 31, 2018, included The Villages Insurance Partners, LLC (“TVIP”) and the Company’s joint ventures, BKS-IPEO JV Partners, LLC (“iPEO”), Laureate Insurance Partners, LLC (“Laureate”), BKS Smith, LLC (“Smith”), BKS MS, LLC (“Saunders”) and BKS Partners Galati Marine Solutions, LLC (“Galati”). In connection with the Initial Public Offering and Reorganization Transaction, the Company acquired the equity interests of TVIP and iPEO, which became wholly-owned subsidiaries of BRP and, accordingly, are no longer VIEs of the Company. The Company has consolidated its VIEs into the consolidated financial statements. Total revenues and expenses of the Company’s consolidated VIEs included in the consolidated statements of comprehensive income (loss) were $579,000 and $727,000 , respectively, for the year ended December 31, 2019 and $13.4 million and $9.5 million , respectively, for the year ended December 31, 2018 . The assets of the consolidated VIEs can only be used to settle the obligations of the consolidated VIEs and the creditors of the liabilities of the consolidated VIEs do not have recourse to the Company. The following tables provide a summary of the carrying amounts of the assets and liabilities of the Company’s consolidated VIEs at each of the balance sheet dates: At December 31, 2019 (in thousands) Laureate Smith Saunders Total Assets Cash and cash equivalents $ 46 $ 1 $ — $ 47 Premiums, commissions and fees receivable, net — 44 31 75 Total current assets 46 45 31 122 Property and equipment, net 31 — — 31 Other assets 5 — 2 7 Total assets $ 82 $ 45 $ 33 $ 160 Liabilities Premiums payable to insurance companies $ 3 $ — $ 3 $ 6 Producer commissions payable 2 5 8 15 Accrued expenses and other current liabilities 4 25 — 29 Total liabilities $ 9 $ 30 $ 11 $ 50 At December 31, 2018 (in thousands) TVIP iPEO Laureate Smith Saunders Total Assets Cash and cash equivalents $ 770 $ 1 $ 25 $ — $ — $ 796 Premiums, commissions and fees receivable, net 1,171 2,725 — — 6 3,902 Prepaid expenses and other current assets 50 14 5 — — 69 Due from related parties — — 13 — — 13 Total current assets 1,991 2,740 43 — 6 4,780 Property and equipment, net 74 — 41 — — 115 Other assets 2 — — — — 2 Goodwill 4,035 — — — — 4,035 Total assets $ 6,102 $ 2,740 $ 84 $ — $ 6 $ 8,932 Liabilities Premiums payable to insurance companies $ 29 $ 2,043 $ — $ — $ 6 $ 2,078 Producer commissions payable 227 282 — 5 — 514 Accrued expenses and other current liabilities 316 2 1 1 — 320 Total liabilities $ 572 $ 2,327 $ 1 $ 6 $ 6 $ 2,912

Revenue from Contract with Customer [Abstract]
Revenue	Revenue The following table provides disaggregated commissions and fees revenue by major source: For the Years Ended December 31, (in thousands) 2019 2018 Direct bill revenue (1) $ 70,835 $ 52,210 Agency bill revenue (2) 43,619 17,967 Profit-sharing revenue (3) 9,598 6,007 Policy fee and installment fee revenue (4) 8,154 — Consulting and service fee revenue (5) 2,709 2,660 Other income (6) 2,926 1,036 Total commissions and fees $ 137,841 $ 79,880 __________ (1) Direct bill revenue represents commission revenue earned by facilitating the arrangement between individuals or businesses and Insurance Company Partners to provide insurance placement services to Clients, primarily for private risk management, commercial risk management, employee benefits and Medicare insurance types. (2) Agency bill revenue primarily represents commission revenue earned by facilitating the arrangement between individuals or businesses and Insurance Company Partners to provide insurance placement services to Clients. The Company acts as an agent on behalf of the Client for the term of the insurance policy. (3) Profit-sharing revenue represents bonus-type revenue that is earned by the Company as a sales incentive provided by certain Insurance Company Partners. (4) Policy fee revenue represents revenue earned for acting in the capacity of an MGA on behalf of the Insurance Company Partner and fulfilling certain services including delivery of policy documents, processing payments and other administrative functions. Installment fee revenue represents revenue earned by the Company for providing payment processing services on behalf of the Insurance Company Partner related to policy premiums paid on an installment basis. (5) Service fee revenue is earned by receiving negotiated fees in lieu of a commission and consulting revenue is earned by providing specialty insurance consulting. (6) Other income consists primarily of Medicare marketing income that is based on agreed-upon cost reimbursement for fulfilling specific targeted marketing campaigns. The application of Topic 606 requires the use of management judgment. The following are the areas of most significant judgment as it relates to Topic 606: • The Company considers the policyholders as representative of its customers in the majority of contractual relationships, with the exception of contracts in its Medicare operating segment, where the Insurance Company Partner is considered its customer. • Contracts in the Medicare operating segment are multi-year arrangements in which BRP is entitled to renewal commissions. However, the Company has applied a constraint to renewal commission that limits revenue recognized on new policies to the policy year in effect, and revenue recognized on renewed policies to the receipt of periodic cash, when a risk of significant reversals exists based on: (i) insufficient history; and (ii) the influence of external factors outside of the Company’s control including policyholder discretion over plans and Insurance Company Partner relationship, political influence, and a contractual provision, which limits the Company’s right to receive renewal commissions to ongoing compliance and regulatory approval of the relevant Insurance Company Partner and compliance with the Centers for Medicare and Medicaid Services (CMS). • The Company recognizes separately contracted commissions revenue at the effective date of insurance placement and considers any ongoing interaction with the customer to be immaterial in the context of the contract. • Variable consideration includes estimates of direct bill commissions, a reserve for policy cancellations and an estimate of profit-sharing income. • Costs to obtain a contract are deferred and recognized over a five-year period, which represents management’s estimate of the average period over which a Client maintains its initial coverage relationship with the original Insurance Company Partner. • Due to the relatively short time period between the information gathering phase and binding insurance coverage, the Company has determined that costs to fulfill contracts are not significant. Therefore, costs to fulfill a contract are expensed as incurred.

The incentive rights could be converted to LLC Units after the achievement of certain milestones, subject to approval at the discretion of management. Certain Risk Advisors were deemed probable of meeting the performance condition after having achieved the first milestone related to their advisor incentive agreements. On a quarterly basis thereafter, the Company estimated the fair value of each advisor’s book of business and recorded compensation expense and an increase to the advisor incentive liability. The Company recognized compensation expense related to advisor incentives of $1.1 million and $1.2 million for the years ended December 31, 2019 and 2018 , respectively. In conjunction with the Reorganization Transactions, the Company exchanged $2.2 million of its obligation related to advisor incentive liabilities for 204,807 restricted shares of Class A common stock issued under the Company’s Omnibus Incentive Plan. The Company established stockholder notes receivable of $452,000 for the remaining deposit buy-in amounts due from the advisors and relieved advisor incentive liabilities for $2.2 million with an offset to additional paid-in capital of $2.6 million . Under an agreement with one of its Risk Advisors, the Company has an obligation to purchase the advisor’s book of business upon certain termination events and for which the Company has recorded an advisor incentive liability for the expected buyout amount. The change in value of the related advisor incentive liability resulted in compensation expense of $421,000 and $821,000 for the years ended December 31, 2019 and 2018 , respectively, which is included in total compensation expense related to advisor incentives discussed above. Although all remaining advisors exchanged their advisor incentive rights into common stock in connection with the Reorganization Transactions as discussed above, this Risk Advisor chose not to convert his incentive rights into common stock of BRP Group. As a result, this advisor’s incentive liability remains outstanding at December 31, 2019 and the Company will continue to estimate the fair value of the expected buyout amount each reporting period until a termination event occurs. Participation Unit Ownership Plan Liabilities The Company issued 11,700 and 14,000 participation units to Colleagues during the years ended December 31, 2019 and 2018 . The Company recognized compensation expense related to the issuance of these units of approximately $50,000 and $158,000 for the years ended December 31, 2019 and 2018 , respectively. At December 31, 2018, the Company had a total of 43,689 participation units outstanding and a liability related to these participation units of approximately $262,000 . No participation units vested during the years ended December 31, 2019 and 2018 . In conjunction with the Reorganization Transactions, the Company’s obligation under the Participation Plan of $311,000 was exchanged for 22,243 restricted shares of Class A common stock issued under the Company’s Omnibus Incentive Plan, which resulted in an offset to additional paid-in capital of $311,000 .

Debt Disclosure [Abstract]
Long-term Debt	Long-Term Debt At December 31, 2017, the Company had outstanding borrowings under an amended and restated credit agreement with Cadence Bank, N.A. (as subsequently amended and restated, the “JPMorgan Credit Agreement”), which provided for a $3.0 million term loan (the “Term Loan”), of which the full principal amount was previously advanced, a $2.0 million revolving credit facility to be used for working capital purposes (the “Working Capital Line”) and a $20.0 million revolving credit facility to be used for acquisition purposes (the “Acquisitions Line” and collectively with the Working Capital Line, the “Revolving Lines of Credit”) due in May 2023 . On May 31, 2018, the Company entered into the second amendment to the JPMorgan Credit Agreement (the “Second Amendment”) with Cadence Bank N.A. as lead arranger in a syndicated credit agreement, which provided for a $2.2 million Term Loan, of which the full principal amount was previously advanced, a $2.0 million Working Capital Line and a $50.0 million Acquisitions Line. The Company recorded debt issuance costs related to the Second Amendment of $356,000 during the year ended December 31, 2018. The Second Amendment was accounted for as a modification of debt, and therefore, the previously unamortized debt costs continued to be amortized over the term of the new agreement. The Term Loan required quarterly principal payments of $107,648 through the maturity date in May 2023 , at which time all remaining unpaid amounts were due. The Revolving Lines of Credit required monthly interest payments. Interest was payable monthly based on London Interbank Offered Rate (“LIBOR”) plus an applicable margin. The applicable interest rate was 6.00% at December 31, 2018. In addition, any unused commitment on the Revolving Lines of Credit accrued a commitment fee of 0.25% per annum. The balance of the Term Loan, Working Capital Line and Acquisitions Line was $1.9 million , $0.5 million and $33.4 million , respectively, at December 31, 2018. On March 13, 2019, the Company entered into the third amended and restated JPMorgan Credit Agreement (the “Third Amendment”), which (i) increased the borrowing capacity of the Acquisitions Line to $103.0 million ; (ii) increased the outstanding balance of the Acquisitions Line by $50.8 million ; (iii) paid off the outstanding balance of the Term Loan with funds from the Acquisitions Line; and (iv) extended the maturity date on the Revolving Lines of Credit to March 13, 2024 . The remaining terms of the JPMorgan Credit Agreement remained substantially unchanged. The Company recorded debt issuance costs related to the Third Amendment of $775,000 during the year ended December 31, 2019 . The Third Amendment was accounted for as a partial extinguishment and partial modification at the individual tranche and syndicated lender level. Most of the previously unamortized deferred financing costs continued to be amortized over the term of the new agreement. The Company recorded a loss on extinguishment of debt related to the Third Amendment of $115,000 during the year ended December 31, 2019 . On September 21, 2019, the Company executed the first amendment to the Third Amendment (“Amendment No. 1”), which became effective concurrent with the Initial Public Offering and resulted in a borrowing capacity of $10.0 million for the Working Capital Line and $115.0 million for the Acquisitions Line. Amendment No. 1 also extended the maturity date of the JPMorgan Credit Agreement to October 28, 2024 . The Company recorded debt issuance costs related to Amendment No. 1 of $179,000 during the year ended December 31, 2019 . Amendment No. 1 was accounted for as a partial extinguishment and partial modification at the individual tranche and syndicated lender level. Most of the previously unamortized deferred financing costs continued to be amortized over the term of the new agreement. The Company recorded a loss on extinguishment of debt related to Amendment No. 1 of $260,000 during the year ended December 31, 2019 . On November 25, 2019, the Company repaid a portion of the Revolving Lines of Credit in the amount of $65.0 million , which resulted in remaining borrowing capacity of $85.0 million under the JPMorgan Credit Agreement. On December 19, 2019 , the Company executed the fourth amended and restated JPMorgan Credit Agreement (the “Fourth Amendment”), which (i) replaced the existing Revolving Lines of Credit with a revolving credit commitment (the “Revolving Credit Commitment”) with an aggregate borrowing capacity of $225.0 million , of which no more than $65.0 million is available for working capital purposes and the entirety of which is available to fund acquisitions permitted under the JPMorgan Credit Agreement; (ii) replaced Cadence Bank, N.A. as existing agent with JPMorgan Chase Bank, N.A. as successor agent and lead arranger; and (iii) changed the maturity date of the JPMorgan Credit Agreement to September 23, 2024 . The facility also has an accordion feature that allows the Company to increase the aggregate borrowing capacity to $300.0 million , which we utilized by entering into the Incremental Facility Amendment No. 1 to the JP Morgan Credit Agreement on March 12, 2020 . The Company recorded debt issuance costs related to the Fourth Amendment of $541,000 during the year ended December 31, 2019 . The Fourth Amendment was accounted for as a partial extinguishment and partial modification at the individual tranche and syndicated lender level. Most of the previously unamortized deferred financing costs continued to be amortized over the term of the new agreement. The Company recorded a loss on extinguishment of debt related to the Fourth Amendment of $167,000 during the year ended December 31, 2019 . The outstanding balance of the Revolving Credit Commitment was $40.4 million at December 31, 2019 . The Revolving Credit Commitment is collateralized by a first priority lien on substantially all the assets of the Company, including a pledge of all equity securities of each of its subsidiaries. The interest rate of the Revolving Credit Commitment is based on, depending on the type of loan, the Eurodollar rate or the Alternative Based Rate, plus in each case, a margin based on Total Leverage Ratio (as defined in the JPMorgan Credit Agreement) as set forth in the pricing grid below, provided that under no circumstances will the LIBO Rate (as defined in the JPMorgan Credit Agreement) used in the determination of the Eurodollar rate be less than 0.00% or the Alternate Base Rate be less than 1.00% : Total Net Leverage Ratio Applicable Margin for Eurodollar Loans Applicable Margin for Alternate Base Rate Loans Commitment Fee on Unfunded Commitments < 2.50x 200 bps 100 bps 25 bps ≥ 2.50x < 3.00x 225 bps 125 bps 30 bps ≥ 3.00x < 3.75x 250 bps 150 bps 35 bps ≥ 3.75x 300 bps 200 bps 40 bps At December 31, 2019 , the variable rate in effect for the JPMorgan Credit Agreement was LIBOR due to a repricing option and the applicable interest rate on the Revolving Credit Commitment was 3.81% . The JPMorgan Credit Agreement requires the Company to meet certain financial covenants and comply with customary affirmative and negative covenants as listed in the underlying agreement.

Equity [Abstract]
Mezzanine Equity [Text Block]	Mezzanine Equity Redeemable members’ capital and redeemable noncontrolling interest are classified in mezzanine equity on the Company’s consolidated balance sheets. Redeemable members’ capital is comprised of the voting common units of BRP’s two minority holders and Holding Company of the Villages, Inc. (“Villages”) as discussed below. Redeemable Members’ Capital Voting Common Units of Two Minority Founders Voting Common Units of two minority founders (“Minority Founders’ Units”) require redemption upon death; however, the controlling founder has the unilateral right to effect a change in control with drag-along rights that terminate the redemption provision. The Company has concluded that the controlling founder’s rights represent a conditional future event that scopes the Minority Founders’ Units out of the guidance pertaining to mandatorily redeemable instruments; thus, the Minority Founders’ Units are presented as redeemable members’ capital. The Minority Founders’ Units also contain certain put and call rights in conjunction with termination at the greater of fair value or a floor, as defined in the Operating Agreement. The Minority Founders’ Units are reported at estimated redemption value in redeemable members’ capital and are measured as the greater of estimated fair value at the end of each reporting period or the historical cost basis of the redeemable common units adjusted for cumulative earnings or loss allocations. During March 2019, the Company repurchased 595,780 Minority Founders’ Units for $12.5 million . In conjunction with the Reorganization Transactions as discussed in Note 3 , the Company executed its call rights for the Minority Founders’ Units, which were converted into permanent equity consisting of 5,701,107 shares of Class B common stock and LLC Units. Villages Voting Common Units The Company issued 293,660 and 261,604 Voting Common Units to Villages during the years ended December 31, 2019 and 2018 , respectively (see Note 18 ). In accordance with the Company’s Operating Agreement, a Member may transfer all or any of its units to a Permitted Transferee, as defined by the Operating Agreement, without the prior written consent of Common Members. Villages transferred 293,660 and 261,604 Voting Common Units to a Permitted Transferee during the years ended December 31, 2019 and 2018 , respectively. Transfers to any other individual not defined as a Permitted Transferee must be approved by written consent of the Common Members. Villages holds certain put rights and the Company holds certain call rights with respect to Voting Common Units (“Villages’ Units”) issued in connection with the Company’s non-revolving loan with Villages (“Related Party Debt”), which is described in Note 18 . Villages had the right to require the Company to redeem all, but not less than all, of the Villages’ Units and its Permitted Transferees, as defined by the agreement, by sending a written notice of exercise of such option to the Company. Villages’ put right can be redeemed at any time after the later of the maturity date of the Related Party Debt (April 2024) or sixty-six months after the date of the agreement (October 2021). In the event that the Related Party Debt is prepaid in full prior to the scheduled maturity date, the date of such prepayment shall be deemed to be the maturity date. The Company had the right to redeem all (but not less than all) of Villages’ Units by sending a written notice of exercise of such option to the Company, provided that the Company has or can obtain the financial resources to pay the entire purchase price for Villages’ Units in cash at the closing of the purchase and sale. The Company’s call right can be redeemed at any time after the later of the date that all outstanding principal, accrued interest and all other charges due under the Related Party Debt are paid in full or sixty-six months after the date of the agreement (October 2021). In each event, the purchase price for Villages’ Units shall be the fair market value as of the date that such option was exercised. In conjunction with the Reorganization Transactions, the Company executed its call rights for the Villages Units, which were converted into permanent equity consisting of 3,077,559 shares of Class B common stock and LLC Units. Redeemable Noncontrolling Interest Sean D. Ryan, Gagnon and AHI Members, W. David Cox and Michael P. Ryan, Wentzell, Chris Black, Montoya & Associates, and AB Holdco (each a “Rollover Member” and collectively, the “Rollover Members”) held certain put rights and the Company holds certain call rights with respect to Non-Voting Common Units issued to Rollover Members (“Rollover Members’ Units”) in connection with business acquisitions. Each Rollover Member, other than W. David Cox and Michael P. Ryan, had the right to require the Company to redeem all (but not less than all) of the Rollover Members’ Units, by sending a written notice of exercise of such option to the Company. Rollover Members W. David Cox and Michael P. Ryan had the right to require the Company to redeem all or any portion of the Rollover Members’ Units under the same circumstances. The Rollover Members’ put rights could be redeemed at any time after forty-eight months from the date of the respective agreement for all Rollover Members other than Chris Black, Montoya & Associates, and AB Holdco for which the put rights can be redeemed at up to 25% per year for each of the four years after forty-eight months from the date of the respective agreement. The Company had the right to redeem all (but not less than all) of the Rollover Members’ Units by sending a written notice of exercise of such option to the Rollover Member, provided that the Company has or can obtain the financial resources to pay the entire purchase price for the Rollover Member’s Units in cash at the closing of the purchase and sale. The Company’s call right could be redeemed at any time after the earlier of a termination event, as defined in the agreement, or forty-eight months after the date of the respective agreement. In each event, the purchase price for the Rollover Members’ Units was the fair market value as of the date that such option was exercised, excluding any discount for lack of marketability or lack of control. In conjunction with the Reorganization Transactions as discussed in Note 3 , the Company executed its call rights for the majority of the Rollover Members’ Units, which were converted into permanent equity consisting of 9,615,911 shares of Class B common stock and LLC Units. Rollover Members equity holdings held by Smith and Saunders, two of the Company’s VIEs, were not converted to permanent equity and remain redeemable and a component of redeemable noncontrolling interest subsequent to the conversion. All put rights no longer exist; however, some of these LLC Units and Class B common stock are not eligible to be converted into A shares until certain time has passed since the initial acquisition.

Equity [Abstract]
Members' Equity Notes Disclosure [Text Block]	Members’ Equity (Deficit) and Noncontrolling Interest At December 31, 2018, members’ equity (deficit) included Voting Common Units of the majority founder, Management Incentive Units and certain noncontrolling interests without redemption rights. Management Incentive Units are discussed in Note 19 . Voting Common Units Voting Common Units held by the majority founder (“Majority Founder’s Units”) are presented as a component of members’ deficit on the consolidated balance sheets. The Company may issue, and a Member may own, one or more classes of units. A Member is defined as any person on record as the owner of one or more units. In conjunction with the Reorganization Transactions as discussed in Note 3 , the Majority Founder’s Units were converted into 18,933,907 shares of Class B common stock and LLC Units. Noncontrolling Interest Non-Voting Common Units are non-voting units issued to Risk Advisors upon achievement of certain milestones in accordance with advisor incentive agreements or to Partners in connection with business acquisitions. Transfers of Non-Voting Common Units to any other individual must be approved by written consent of the Common Members. Non-Voting Common Units are classified as noncontrolling interest in the consolidated balance sheet. During 2018, a Risk Advisor contributed capital to BKS in connection with certain business combinations and was issued an additional 6,765 Non-Voting Common Units. During May 2019, a member of senior management exercised his option to purchase 61,982 Non-Voting Common Units of BRP for $612,000 . In conjunction with the Reorganization Transactions as discussed in Note 3 , the majority of Non-Voting Common Units were converted into permanent equity consisting of 232,596 shares of Class B common stock and LLC Units. Non-Voting Common Units held by Laureate, a VIE, were not converted to permanent equity, and therefore, remain a component of redeemable noncontrolling interest subsequent to the reorganization.

Shareholders of Class A common stock are entitled to receive dividends when and if declared by our board of directors, subject to any restrictions on the payment of dividends. Upon our liquidation, dissolution or winding up and after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the shareholders of Class A common stock will be entitled to receive pro rata our remaining assets available for distribution. Class B Common Stock Each share of Class B common stock entitles the stockholder to one vote per share on all matters submitted to a vote of our stockholders. If at any time the ratio at which LLC Units are redeemable or exchangeable for shares of Class A common stock changes from one-for-one, the number of votes to which Class B common stockholders are entitled will be adjusted accordingly. Class B common stockholders do not have cumulative voting rights in the election of directors. Except for transfers to us pursuant to the Amended LLC Agreement or to certain permitted transferees, the holders of LLC Units are not permitted to sell, transfer or otherwise dispose of any LLC Units or shares of Class B common stock.

Noncontrolling Interest In connection with the Initial Public Offering and the Reorganization Transactions, BRP Group became the sole managing member of BRP. As a result, BRP Group began consolidating BRP in its consolidated financial statements as of the closing date of the Initial Public Offering, resulting in a noncontrolling interest related to the LLC Units held by BRP’s members on its consolidated financial statements. Noncontrolling interest previously represented Partners’ equity interests in underlying subsidiaries. Refer to Note 3 for additional information regarding the Reorganization Transactions’ effect on equity. Under the Amended LLC Agreement, BRP’s LLC Members have the right, from and after the completion of the Initial Public Offering (subject to the terms of the Amended LLC Agreement), to require BRP Group to redeem all or a portion of their LLC Units for, at BRP Group’s election, newly-issued shares of Class A common stock on a one-for-one basis or a cash payment equal to the volume weighted average market price of one share of BRP Group’s Class A common stock for each LLC Unit redeemed. Additionally, in the event of a redemption request by a BRP LLC Member, BRP Group may, at its option, effect a direct exchange of cash or Class A common stock for LLC Units in lieu of such a redemption. Shares of Class B common stock will be canceled on a one-for-one basis if BRP Group, at the election of a BRP LLC Member, redeems or exchanges LLC Units of such BRP LLC Member pursuant to the terms of the Amended LLC Agreement. Except for transfers to BRP Group pursuant to the Amended LLC Agreement or to certain permitted transferees, BRP’s LLC Members are not permitted to sell, transfer or otherwise dispose of any LLC Units or shares of Class B common stock.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Several of the Reorganization Transactions discussed previously in these notes to consolidated financial statements are related party transactions entered into between the Company and its equity holders and employees. Refer to Note 3 for additional information regarding the Reorganization Transactions. Due from Related Parties Due from related parties totaling $43,000 and $117,000 at December 31, 2019 and 2018 , respectively, consists of amounts due from related party entities in connection with newly formed partnerships. Villages Transactions Related Party Debt During April 2016, the Company entered into the Villages Credit Agreement, which provided for a $100.0 million non-revolving line of credit (“Related Party Debt”) with Holding Company of the Villages, Inc. (“Villages”). The Related Party Debt required quarterly interest payments at a fixed rate per annum of 6.5% beginning July 1, 2016 and continuing on the first day of each calendar quarter thereafter until maturity in April 2023 . The agreement required that the Company issue Voting Common Units to Villages upon closing and concurrently with each additional advance made after the closing date. Advances on the Related Party Debt were to be made solely to finance permitted acquisitions or for general working capital purposes. The outstanding balance of the Related Party Debt was $36.9 million at December 31, 2018. The Villages Credit Agreement required that the Company issue Voting Common Units to Villages concurrently with each additional advance made on the non-revolving line of credit. The Company issued 261,604 units at a share price of $11.50 in connection with these advances during the year ended December 31, 2018 based on the most recent Company valuation. The issuance of these Voting Common Units is reflected in redeemable members’ capital in the accompanying consolidated statements of members’ equity (deficit) and mezzanine equity at December 31, 2018. Total expense incurred related to the issuance of these Voting Common Units was $3.0 million for the year ended December 31, 2018 . This expense is included in interest expense in the consolidated statements of comprehensive income (loss) as the issuance most closely represented fees paid to Villages as a replacement for a debt discount. During March 2019, the Company amended and restated the Villages Credit Agreement, which (i) increased the principal borrowing amount of the Related Party Debt to $125.0 million , (ii) increased the interest rate to a fixed rate of 8.75% per annum, and (iii) changed the maturity date to September 2024 . As consideration for the increase in the interest rate, the Company was no longer required to issue additional Voting Common Units to Villages upon the closing of each additional advance. In addition, the Company issued 293,660 Voting Common Units with a share price of $18.76 to Villages on the closing date as consideration for the additional borrowing capacity. The Company recorded $5.5 million of noncash debt issuance costs related to the issuance of these Voting Common Units during the year ended December 31, 2019 as these Voting Common Units were issued as consideration for the refinancing. The Company also recorded an additional $1.7 million of debt issuance costs in connection with the refinancing during the year ended December 31, 2019 . The refinancing did not qualify for extinguishment, and therefore, the previously unamortized deferred financing costs continued to be amortized over the term of the new agreement. On October 28, 2019 , BRP used a portion of the proceeds it received from the sale of LLC Units to BRP Group in connection with the Initial Public Offering to repay in full the outstanding indebtedness and accrued interest under the Villages Credit Agreement in the amount of $89.0 million and concurrently terminated the Villages Credit Agreement. The Company recorded a loss on debt extinguishment of $6.2 million in connection therewith during the year ended December 31, 2019 . The Company recorded interest expense related to quarterly interest payments to Villages of $4.9 million and $1.8 million for the years ended December 31, 2019 and 2018 , respectively. Commission Revenue The Company serves as a broker for Villages. Commission revenue recorded as a result of these transactions was $1.3 million and $1.4 million for the years ended December 31, 2019 and 2018 , respectively. Rent Expense The Company has various agreements to lease office space from wholly-owned subsidiaries of Villages. Rent expense ranges from approximately $2,000 to $12,500 per month, per lease. Lease agreements expire on various dates through 2023 . Total rent expense incurred with respect to Villages and its wholly-owned subsidiaries was $499,000 and $493,000 for the years ended December 31, 2019 and 2018 , respectively. Other Commission Revenue The Company serves as a broker for certain entities in which a member of our board of directors has a material interest. Commission revenue recorded as a result of these transactions was $238,000 and $255,000 for the years ended December 31, 2019 and 2018 , respectively. Other Rent Expense The Company has various agreements to lease office space from other related parties. Rent expense ranges from approximately $1,000 to $21,000 per month, per lease. Lease agreements expire on various dates through 2029 . Total rent expense incurred with respect to related parties other than Villages was $761,000 and $422,000 for the years ended December 31, 2019 and 2018 , respectively.

Share-Based Compensation

Share-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Management Incentive Units Management Incentive Units (“MIUs”) are non-voting units issued to certain senior management. Issuances can vest immediately or be subject to vesting terms according to time-based benchmarks or performance-based benchmarks that vary between issuance. MIUs are forfeited if certain vesting provisions are not met. Certain MIUs participate in distributions from the date of issuance while other MIUs were issued at a profits interest and therefore only participate in distributions in the event of liquidation. For the MIUs that management has deemed not probable of vesting, no share-based compensation expense is recorded. The following table summarizes the activity for awards granted by the Company under the MIU Plan: Shares Weighted-Average Grant-Date Fair Value Per Share Weighted-Average Contractual Term (in years) Outstanding at January 1, 2018 376,520 $ 2.20 0.98 Granted 343,660 4.18 Outstanding at December 31, 2018 720,180 3.15 1.90 Granted 475,900 7.34 Forfeited (40,000 ) 2.97 Exchanged for options (10,000 ) 2.97 Exchanged for Class B common stock (1,146,080 ) 4.90 Outstanding at December 31, 2019 — — — The Company recorded compensation expense related to MIUs of $1.9 million and $309,000 for the years ended December 31, 2019 and 2018 , respectively, which is included in commissions, employee compensation and benefits in the consolidated statements of comprehensive income (loss). The compensation expense recorded for the year ended December 31, 2019 includes $1.1 million associated with certain awards for which the vesting was accelerated in connection with the successful Initial Public Offering, In conjunction with the Reorganization Transactions, MIUs were converted to 5,627,155 restricted shares of Class B common stock and LLC Units, which contain identical vesting conditions to the original MIU issuances. There were 2,504,341 Class B shares related to the MIU Plan that were fully vested upon the issuance and another 1,165,586 shares that vested by December 31, 2019 . The following table summarizes the number of non-vested shares of Class B common stock related to the MIU Plan that are expected to vest in each of the following years: For the Years Ending December 31, Class B Shares 2020 609,500 2021 466,279 2022 451,222 2023 430,227 Valuation Assumptions The fair value of each time-based and performance-based MIUs is estimated on the grant date using the Black-Scholes Model using the assumptions noted in the following table. Expected volatility is based on the historical volatility of a peer group of public and private companies. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant. The assumptions noted in the table below represent the weighted average of each assumption for each grant during the year. For the Years Ended December 31, 2019 2018 Expected volatility 26.1 % 26.0 % Expected dividend yield 0.2 % — % Expected life (in years) 7.0 7.0 Risk-free interest rate 3.1 % 3.2 % For certain MIUs granted in May and September 2019, the individuals are not entitled to dividends and therefore, an estimated dividend yield rate of 1.2% and 1.4% , respectively, was applied as management’s best estimate of future dividends based on projections and industry data. Omnibus Incentive Plan On October 24, 2019, the Company adopted the BRP Group, Inc. Omnibus Incentive Plan (the “Omnibus Plan”) to motivate and reward employees (“Colleagues”) and other individuals to perform at the highest level and contribute significantly to the Company’s success, thereby furthering the best interests of BRP Group’s shareholders. The Omnibus Plan permits the grant of stock options (both nonqualified and incentive stock options), stock appreciation rights (the “SARs”), restricted stock awards, restricted stock unit awards, or RSUs, performance awards, other cash-based awards and other stock-based awards to the Company’s officers, employees, non-employee directors and consultants and advisors. Such awards may be for partial-year, annual or multi-year periods. The Omnibus Plan provides for the Company to make awards of 696,000 shares of Class A common stock at December 31, 2019. The number of shares of Class A common stock reserved for issuance will increase automatically on the first day of each fiscal year by the lesser of (i) 2% of outstanding shares of Class A common stock and Class B common stock on the last day of the immediately preceding fiscal year and (ii) such number of shares as determined by BRP Group’s board of directors. In accordance therewith, the number of authorized shares of Class A common stock reserved for issuance under the plan increased by 1,252,414 shares at January 1, 2020. The Omnibus Plan is administered by the Compensation Committee, the majority of the members of which are independent members of the Board of Directors. Under the Omnibus Plan, the aggregate value of all compensation paid to a non-employee director under the plan in any calendar year may not exceed $250,000 . Each contractual term of an option granted is fixed by the Compensation Committee, and except for limited circumstances, the term cannot exceed ten years from the grant date. Restricted stock awards, RSUs and performance-share awards have a vesting period as defined by the applicable award agreement. At December 31, 2019 , there were 192,316 shares underlying the Omnibus Plan that were authorized, but not yet granted. The Company issues new shares of Class A common stock upon the exercise of stock options, the vesting of RSUs and performance shares and the grant of restricted stock awards. In connection with the Initial Public Offering, BRP Group granted an aggregate of 273,880 shares of restricted stock under the Omnibus Plan to its Colleagues, subject to four -year cliff vesting. These grants are one-time grants solely related to the Initial Public Offering. In addition and as discussed further in Note 3 , the Company issued 204,807 and 22,243 shares of restricted stock in connection with settling its obligations under the Advisor Incentive Plan and the Participation Plan, respectively. The Advisor Incentive Plan awards and the Participation Plan awards are subject to the vesting requirements of the original awards. The Company issued new shares of Class A common stock upon the grant of these restricted stock awards. Although these restricted stock awards are not fully vested, the Class A common shares are considered outstanding for purposes of these financial statements. On December 5, 2019, the Company granted an aggregate of 2,754 shares of restricted stock under the Omnibus Plan to its non-employee directors, which vested immediately upon issuance. The following table summarizes the activity for non-vested awards granted by the Company under the Omnibus Plan: Shares Weighted-Average Grant-Date Fair Value Per Share Weighted-Average Contractual Term (in years) Aggregate Intrinsic value (in thousands) Outstanding at January 1, 2019 — Granted 503,684 $ 14.00 2.52 Vested and settled (173,440 ) 13.99 $ — Outstanding at December 31, 2019 330,244 14.00 3.66 677 Non-vested shares expected to vest as of December 31, 2019 258,333 14.00 3.63 530 The total fair value of shares that vested and settled during the year ended December 31, 2019 was $2.4 million . The Company recognizes share-based compensation expense for the Omnibus Plan net of actual forfeitures. The Company recorded share-based compensation expense of $204,000 in connection with the Omnibus Plan for the year ended December 31, 2019 , which is included in commissions, employee compensation and benefits expense on the consolidated statements of comprehensive income (loss). The Company had $4.0 million of total unrecognized compensation cost related to unvested shares of restricted stock at December 31, 2019 , which is expected to be recognized over a weighted-average period of 3.8 years . Issuance of Unvested Class B Shares On December 27, 2019, the Company issued 69,503 unvested shares of Class B common stock and LLC units to an executive officer outside of the Omnibus Plan. These shares vest 20% on September 30 of each of the following five years . These Class B common shares and LLC Units have a grant-date fair value of $15.55 per share and a contractual vesting term of 4.7 years .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes As a result of the Initial Public Offering and the Reorganization Transactions, BRP Group became the sole managing member of BRP, which is treated as a partnership for U.S. federal, state and local income tax purposes. As a partnership, BRP is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by BRP is passed through to and included in the taxable income or loss of its partners, including BRP Group, on a pro rata basis. BRP Group is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to BRP Group’s allocable share of income of BRP. As the Initial Public Offering occurred during the year ended December 31, 2019 , and BRP Group had no business transactions or activities prior to the Initial Public Offering, no amounts related to the provision for income taxes were incurred for the period from January 1, 2019 to October 27, 2019 or for the year ended December 31, 2018. Components of income tax expense include the following: (in thousands) For the Year Ended December 31, 2019 Current Federal $ 13 State and local 4 Total tax expense $ 17 Income tax expense (benefit) at the Company’s effective tax rate differed from the statutory tax rate as follows: (in thousands) For the Year Ended December 31, 2019 Income (loss) before income taxes $ (22,437 ) Noncontrolling interest 3,138 Tax provision at statutory rate (21%) (4,712 ) Effect of: Valuation allowance 2,228 State and local income tax (1,064 ) MIU issuance 328 Meals and entertainment 79 Disability and life insurance 20 Total income tax expense $ 17 The following table summarizes the components of deferred tax assets and liabilities: (in thousands) For the Year Ended December 31, 2019 Deferred tax assets Investment in Partnerships $ 34,729 163(j) limitation carryforward 538 Net operating loss 236 Total deferred tax assets 35,503 Valuation allowance (35,503 ) Net deferred tax assets $ — Deferred tax balances reflect the impact of temporary differences between the carrying amount of assets and liabilities and their tax basis and are stated at the tax rates in effect when the temporary differences are expected to be recovered or settled. The Company assessed the future realization of the tax benefit of its existing deferred tax assets and concluded that it is more likely than not that all of the deferred tax assets will not be realized in the future. As a result, the Company recorded a valuation allowance of $35.5 million against its deferred tax assets at December 31, 2019 . As of December 31, 2019 and 2018 , the Company has not recognized any uncertain tax positions, penalties, or interest as management has concluded that no such positions exist. The Company is subject to examination for tax years beginning with the year ended December 31, 2019 . The Company is not currently subject to income tax audits in any U.S. or state jurisdictions for any tax year. Tax Receivable Agreement BRP intends to make an election under Section 754 of the Internal Revenue Code of 1986, as amended, and the regulations thereunder (the “Code”) effective for each taxable year in which a redemption or exchange of LLC Units and corresponding Class B common stock for shares of Class A common stock occurs. There were exchanges that occurred during 2019 that are expected to result in tax basis adjustments to the assets of BRP that will be allocated to the Company and thus produce favorable tax attributes. The anticipated tax basis adjustments are expected to reduce the amount of tax that BRP Group would otherwise be required to pay in the future. The Company has determined that it is more likely than not that these benefits will not be realized. On October 28, 2019 , BRP Group entered into the Tax Receivable Agreement with BRP’s LLC Members that provides for the payment by BRP Group to BRP’s LLC Members of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that BRP Group actually realizes as a result of (i) any increase in tax basis in BRP assets resulting from (a) acquisitions by BRP Group of BRP’s LLC Units from BRP’s LLC Members in connection with the Initial Public Offering, (b) the acquisition of LLC Units from BRP’s LLC Members using the net proceeds from any future offering, (c) redemptions or exchanges by BRP’s LLC Members of LLC Units and the corresponding number of shares of Class B common stock for shares of Class A common stock or cash or (d) payments under the Tax Receivable Agreement, and (ii) tax benefits related to imputed interest resulting from payments made under the Tax Receivable Agreement. This payment obligation is an obligation of BRP Group, Inc. and not of Baldwin Risk Partners, LLC. For purposes of the Tax Receivable Agreement, the cash tax savings in income tax will be computed by comparing the actual income tax liability of BRP Group, Inc. (calculated with certain assumptions) to the amount of such taxes that BRP Group, Inc. would have been required to pay had there been no increase to the tax basis of the assets of Baldwin Risk Partners, LLC as a result of the redemptions or exchanges and had BRP Group, Inc. not entered into the Tax Receivable Agreement. Estimating the amount of payments that may be made under the Tax Receivable Agreement is by its nature imprecise, insofar as the calculation of amounts payable depends on a variety of factors. While the actual increase in tax basis, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of redemptions or exchanges, the price of shares of our Class A common stock at the time of the redemption or exchange, the extent to which such redemptions or exchanges are taxable and the amount and timing of our income. The Company will account for the effects of these increases in tax basis and associated payments under the Tax Receivable Agreement arising from future redemptions or exchanges as follows: • record an increase in deferred tax assets for the estimated income tax effects of the increases in tax basis based on enacted federal and state tax rates at the date of the redemption or exchange; • to the extent it is estimated that the Company will not realize the full benefit represented by the deferred tax asset, based on an analysis that will consider, among other things, our expectation of future earnings, the Company will reduce the deferred tax asset with a valuation allowance; and • record 85% of the estimated realizable tax benefit (which is the recorded deferred tax asset less any recorded valuation allowance) as an increase to the liability due under the Tax Receivable Agreement and the remaining 15% of the estimated realizable tax benefit as an increase to additional paid-in capital. All of the effects of changes in any of our estimates after the date of the redemption or exchange will be included in net income. Similarly, the effect of subsequent changes in the enacted tax rates will be included in net income.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share is computed by dividing net income (loss) attributable to BRP Group, Inc. by the weighted-average number of shares of Class A common stock outstanding during the period. Diluted earnings (loss) per share is computed giving effect to all potentially dilutive shares of Class B common stock. During the period presented, potentially dilutive securities include restricted stock awards and shares of Class B common stock that are convertible on a one-for-one basis into shares of our Class A common stock. The 330,244 shares of unvested restricted Class A common stock were excluded from the diluted calculation, as their inclusion would have been anti-dilutive as the Company was in a net loss position. In addition, the 43,257,738 shares of Class B common stock have been excluded in computing diluted net earnings per share because including them on an “if-converted” basis would have an anti-dilutive effect. The shares of Class B common stock do not share in the earnings or losses attributable to BRP Group, and therefore, are not participating securities. Accordingly, a separate presentation of basic and diluted earnings per share of Class B common stock under the two-class method has not been included. The following is a calculation of the basic and diluted weighted-average number of shares of Class A common stock outstanding and net loss per share for the year ended December 31, 2019 . The weighted average number of shares of Class A common stock outstanding is based on the actual days in which the shares were outstanding for the period from October 28, 2019 to December 31, 2019. (in thousands, except per share data) October 28, 2019 through December 31, 2019 Basic and diluted net loss per share: Net loss attributable to BRP Group, Inc. $ (8,650 ) Shares used for basic net loss per share: Basic and diluted weighted-average shares of Class A common stock outstanding 17,917 Basic and diluted net loss per share $ (0.48 )

Fair Value Measurements (Notes)

Fair Value Measurements (Notes)	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Topic 820 established a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy under Topic 820 are described below: Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access. Level 2: Inputs to the valuation methodology are quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The carrying amount of the Revolving Credit Commitment approximated fair value at December 31, 2019 as a result of the JPMorgan Credit Agreement having been amended and restated at market terms on December 19, 2019 . The carrying amount of the Revolving Lines of Credit approximated fair value at December 31, 2018 due to the variable interest rate based on the LIBOR at that date. Methodologies used for assets and liabilities measured at fair value on a recurring basis at December 31, 2019 and 2018 are based on limited unobservable inputs. These methods may produce a fair value calculation that may not be indicative of the net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The following table summarizes Company’s liabilities measured at fair value on a recurring basis within each level of the fair value hierarchy: December 31, (in thousands) 2019 2018 Level 3 Contingently returnable consideration $ 70 $ — Level 3 Assets $ 70 $ — Contingent earnout liabilities $ 48,769 $ 9,249 Level 3 Liabilities $ 48,769 $ 9,249 The Company’s contingently returnable consideration at December 31, 2019 represents a contingent right of return from Fiduciary Partners to reimburse the Company for a portion of the purchase price as part of the Fiduciary Partners transaction. The Company has assessed the maximum estimated refund relating to the contingently returnable consideration to be $1.3 million at December 31, 2019 . The Company measures contingently returnable consideration and contingent earnout liabilities at fair value at each reporting period using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability weighted value analysis as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are sales projections over the earnout period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs would result in a significantly higher or lower asset or liability with a higher asset capped by the contractual maximum of the contingently returnable consideration and a higher liability capped by the contractual maximum of the contingent earnout consideration. Ultimately, the asset and liability will be equivalent to the amount settled, and the difference between the fair value estimate and amount settled will be recorded in earnings for business combinations, or as a reduction of the cost of the assets acquired for asset acquisitions. Refer to Note 4 for additional information regarding contingently returnable consideration and contingent earnout consideration recorded in connection with business acquisitions. The fair value of the contingent earnout liabilities is based on the present value of the expected future payments to be made to the companies we have acquired (“Partners”) in accordance with the provisions outlined in the respective purchase agreements, which is a Level 3 fair value measurement. In determining fair value, the Company estimates the Partner’s future performance using financial projections developed by management for the Partner and market participant assumptions that were derived for revenue growth or profitability. Revenue and EBITDA growth rates generally ranged from 10% to 20% . The Company estimates future payments using the earnout formula and performance targets specified in each purchase agreement and these financial projections. These payments are discounted to present value using a risk-adjusted rate that takes into consideration market-based rates of return that reflect the ability of the Partner to achieve the targets. These discount rates generally ranged from 7.25% to 18.25% . Changes in financial projections, market participant assumptions for revenue growth and profitability, or the risk-adjusted discount rate, would result in a change in the fair value of contingent consideration. The fair value of the contingent earnout liability is based on sales projections for the acquired entities, which are reassessed each reporting period. Based on the Company’s ongoing assessment of the fair value of contingent earnout liability, the Company recorded a net increase in the estimated fair value of such liabilities of $10.6 million for the year ended December 31, 2019 . The Company has assessed the maximum estimated exposure to the contingent earnout liabilities to be $103.9 million at December 31, 2019 . The following table sets forth a summary of the changes in the fair value of the Company’s contingently returnable consideration and contingent earnout liabilities, which are measured at fair value on a recurring basis utilizing Level 3 assumptions in their valuation: For the Years Ended December 31, 2019 2018 (in thousands) Contingently Returnable Consideration Contingent Earnout Liabilities Contingent Earnout Liabilities Balance at beginning of year — $ 9,249 $ 4,055 Payment of contingent consideration — (175 ) (2,892 ) Fair value of contingent consideration recorded in connection with business combinations 321 29,101 5,815 Change in fair value of contingent consideration (251 ) 10,578 1,228 Fair value of contingent consideration recorded in connection with asset acquisitions — 16 1,043 Balance at end of year $ 70 $ 48,769 $ 9,249

Segment Reporting [Abstract]
Segment Reporting	Segment Information BRP Group’s business is divided into four Operating Groups: Middle Market, Specialty, MainStreet and Medicare. • Middle Market provides expertly-designed private risk management, commercial risk management and employee benefits solutions for mid-to-large size businesses and high net worth individuals and families. • Specialty represents a wholesale co-brokerage platform that delivers specialty insurers, professionals, individuals and niche industry businesses expanded access to exclusive specialty markets, capabilities and programs requiring complex underwriting and placement. With the addition of the MSI Partnership in April 2019 as discussed in Note 4 , Specialty also represents a leading technology platform. MGA of the Future is a national renter’s insurance product distributed via sub-agent partners and property management software providers, which has expanded distribution capabilities for new products through our wholesale and retail networks. • MainStreet offers personal insurance, commercial insurance and life and health solutions to individuals and businesses in their communities. • Medicare offers consultation for government assistance programs and solutions, including traditional Medicare and Medicare Advantage, to seniors and Medicare-eligible individuals through a network of agents. In the Middle Market, MainStreet and Specialty Operating Groups, the Company generates commissions and fees from insurance placement under both agency bill and direct bill arrangements. In addition, BRP generates profit sharing income in each of those segments based on either the underlying book of business or performance, such as loss ratios. In the Middle Market Operating Group only, the Company generates fees from service fee and consulting arrangements. Service fee arrangements are in place with certain customers in lieu of commission arrangements. In the Medicare Operating Group, BRP generates commissions and fees in the form of direct bill insurance placement and marketing income. Marketing income is earned through co-branded marketing campaigns with the Company’s Insurance Company Partners. The Company’s chief operating decision maker, the chief executive officer, uses net income before interest, taxes, depreciation, amortization, and one-time transactional-related expenses or non-recurring items to manage resources and make decisions about the business. There are no intersegment net sales that occurred during the reporting periods. Summarized financial information concerning BRP’s Operating Groups is shown in the following tables. The “Corporate and Other” column includes any expenses not allocated to the Operating Groups and corporate-related items, including related party and third-party interest expense. Service center expenses and other overhead are allocated to the Company’s Operating Groups based on either revenue or headcount as applicable to each expense.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of BRP Group and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. As the sole manager of BRP, BRP Group operates and controls all the business and affairs of BRP, and has the sole voting interest in, and controls the management of, BRP. Accordingly, BRP Group began consolidating BRP in its consolidated financial statements as of the closing date of the Initial Public Offering, resulting in a noncontrolling interest related to the LLC Units held by BRP’s LLC members on its consolidated financial statements. BRP and BRP Group have been under the common control of our Chairman, Lowry Baldwin, before and after the Reorganization Transactions. Prior to the Reorganization Transactions, Mr. Baldwin held a controlling interest in Baldwin Investment Group Holdings, LLC (“BIGH”), which was the controlling owner of BRP through its majority ownership of BRP’s common units. In addition, Mr. Baldwin was the sole shareholder of BRP Group. Upon reorganization, BRP Group became the sole managing member of BRP. Holders of the Class B common stock hold a majority of the voting power of BRP Group and stockholders of a majority of the Class B common stock, including BIGH, executed a Voting Agreement in which they agreed to vote in the same manner as Mr. Baldwin. As a result, Mr. Baldwin continues to control BRP Group subsequent to the Initial Public Offering and Reorganization Transactions. Accordingly, we have accounted for the Reorganization Transactions as a transaction between entities under common control in accordance with Accounting Standards Codification (“ASC”) Topic 805-50, Business Combinations - Related Issues , under which the financial information of BRP Group has been combined with that of BRP as of the earliest period presented. The Company has prepared these consolidated financial statements in accordance with ASC Topic 810, Consolidation (“Topic 810”). Topic 810 requires that if an enterprise is the primary beneficiary of a variable interest entity, the assets, liabilities, and results of operations of the variable interest entity should be included in the consolidated financial statements of the enterprise. The Company has recognized certain entities as variable interest entities of which the Company is the primary beneficiary and has included the accounts of these entities in the consolidated financial statements. Refer to Note 5 for additional information regarding the Company’s variable interest entities. Topic 810 also requires that the equity of a noncontrolling interest shall be reported in the consolidated balance sheets within total equity of the Company. Certain redeemable noncontrolling interests are reported in the consolidated balance sheets as mezzanine equity. Topic 810 also requires revenues, expenses, gains, losses, net income or loss, and other comprehensive income or loss to be reported in the consolidated financial statements at consolidated amounts, which include amounts attributable to the owners of the parent and the noncontrolling interests. Refer to the Redeemable Noncontrolling Interest and Noncontrolling Interest sections of Note 2 for additional information.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Significant estimates underlying the accompanying consolidated financial statements include the application of guidance for revenue recognition, including determination of allowances for estimated policy cancellations, business combinations and purchase price allocation, impairment of long-lived assets including goodwill, and valuation of the Tax Receivable Agreement liability, advisor incentive liabilities and share-based compensation.
Changes in Presentation	Changes in Presentation Certain prior year amounts have been reclassified to conform to current year presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements As an emerging growth company, the Jumpstart Our Business Startups (“JOBS”) Act permits the Company an extended transition period for complying with new or revised accounting standards affecting public companies. The Company has elected to use this extended transition period and adopt certain new accounting standards on the private company timeline, which means that the Company’s financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards on a non-delayed basis. The Company has elected the extended transition period for the adoption of the Accounting Standards Updates (“ASU”) below, except those where early adoption was both permitted and elected. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases . ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. The FASB has subsequently issued several additional ASUs related to leases, which improved upon, and provided transition relief for, the guidance issued in ASU 2016-02 and extended the adoption date for nonpublic business entities. This guidance is effective for the fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the full effect that the adoption of this standard will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements (“ASU 2016-13”), which amends the guidance for recognizing credit losses on financial instruments measured at amortized cost. ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The FASB has subsequently issued several additional ASUs related to credit losses, which improved upon, and provided transition relief for, the guidance issued in ASU 2016-13 and extended the adoption date for nonpublic business entities. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the full effect that the adoption of this standard will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 provides guidance on the classification of contingent consideration payments made after a business combination and other cash receipts and payments. The Company adopted ASU 2016-15 effective January 1, 2019 and has applied the guidance retrospectively for its consolidated statement of cash flows for the years ended December 31, 2019 and 2018. The Company applied the guidance in ASU 2016-15 to its payment of contingent consideration liabilities related to business combinations and the payment of debt extinguishment costs, which impacted the presentation of the cash flows, but did not otherwise impact on the Company’s results of operations or financial condition. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that the statement of cash flows explain the changes during the period of cash and cash equivalents inclusive of amounts categorized as restricted cash. The Company adopted ASU 2016-18 effective January 1, 2019. With the adoption of ASU 2016-18, the statements of cash flows detail the change in the balance of cash and cash equivalents and restricted cash. The adoption of this guidance did not have any effect on cash flows for the year ended December 31, 2018. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which amends the guidance on goodwill. Under ASU 2017-04, goodwill impairment is measured as the amount by which a reporting unit’s carrying value exceeds its fair value, while not exceeding the carrying value of goodwill. ASU 2017-04 eliminates existing guidance that requires an entity to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all its assets and liabilities as if that reporting unit had been acquired in a business combination. The Company early adopted this guidance for impairment tests effective January 1, 2019 and it did not have any impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) (“Topic 820”): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which modifies the disclosure requirements related to fair value measurement, by removing certain disclosure requirements related to the fair value hierarchy, modifying existing disclosure requirements related to measurement uncertainty and adding new disclosure requirements, such as disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in ASU 2018-13 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), which provides guidance for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company early adopted ASU 2018-15 for implementation costs related to its service contracts effective January 1, 2019 and applied it prospectively for all cloud computing arrangement implementation costs incurred on or after the effective date. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), as part of its Simplification Initiative to reduce the cost and complexity in accounting for income taxes. ASU 2019-12 removes certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. The guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company early adopted ASU 2019-12 in the fourth quarter of 2019. The adoption did not have a material impact on our consolidated financial statements.
Revenue Recognition	Revenue Recognition Effective January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”) and all related amendments that established Topic 606. The Company adopted these standards by recognizing the cumulative effect as an adjustment to opening retained earnings at January 1, 2018 under the modified retrospective method for contracts not completed as of the day of adoption. The Company elected the practical expedient to evaluate only contracts not completed at the date of initial application. The cumulative impact of adopting Topic 606 on January 1, 2018 was an increase in retained earnings and noncontrolling interest within members’ equity (deficit) totaling $6.8 million . The Company earns commission revenue by facilitating the arrangement between Insurance Company Partners and individuals or businesses by providing insurance placement services to insureds (“Clients”) with Insurance Company Partners. Commission revenues are usually a percentage of the premium paid by Clients and generally depend upon the type of insurance, the Insurance Company Partner and the nature of the services provided. In some limited cases, the Company shares commissions with other agents or brokers who have acted jointly with the Company in a transaction. The Company controls the fulfillment of the performance obligation and its relationship with its Insurance Company Partners and the outside agents. Commissions shared with downstream agents or brokers are recorded in commission, employee compensation and benefits expense in the consolidated statements of comprehensive income (loss). Commissions are earned at a point in time upon the effective date of bound insurance coverage as no performance obligation exists after coverage is bound. Commission revenue is recorded net of allowances for estimated policy cancellations, which are determined based on an evaluation of historical and current cancellation data. The Company earns service fee revenue in its Middle Market segment by receiving negotiated fees in lieu of a commission and consulting revenue from services other than securing insurance coverage. Service fee and consulting revenues from certain agreements are recognized over time depending on when the services within the contract are satisfied and when the Company has transferred control of the related services to the customer. Commissions and fees for brokerage services may be invoiced near the effective date of the underlying policy or over the term of the arrangement in installments during the policy period. However, regardless of the payment terms, commissions are recognized at a point in time upon the effective date of bound insurance coverage, as no performance obligation exists after coverage is bound. The Company may receive a profit-sharing commission from an Insurance Company Partner, which is based primarily on underwriting results, but may also contain considerations for volume, growth, loss performance, or retention. Profit-sharing commissions represent a form of variable consideration, which includes additional commissions over base commissions received from Insurance Company Partners. Profit-sharing commissions associated with relatively predictable measures are estimated with a constraint applied and recognized at a point in time. The profit-sharing commissions are recorded as the underlying policies that contribute to the achievement of the metric are placed with any adjustments recognized when payments are received or as additional information that affects the estimate becomes available. Profit-sharing commissions associated with loss performance are uncertain, and therefore, are subject to significant reversal through catastrophic loss season and as loss data remains subject to material change. The constraint is relieved when management estimates revenue that is not subject to significant reversal, which often coincides with the earlier of written notice from the Insurance Company Partner that the target has been achieved, or cash collection. Year-end amounts incorporate estimates based on confirmation from Insurance Company Partners after calculation of potential loss ratios that are impacted by catastrophic losses. The consolidated financial statements include estimates based on constraints and incorporates information received from Insurance Company Partners, and where still subject to significant changes in estimates due to loss ratios and external factors that are outside of the Company’s control, a full constraint is applied. The Company pays an incremental amount of compensation in the form of producer commissions on new business. These incremental costs are capitalized as deferred commission expense and amortized over five years, which represents management’s estimate of the average period over which a Client maintains its initial coverage relationship with the original Insurance Company Partner. The Company has concluded that this period is consistent with the transfer to the customer of the services to which the asset relates. Due to the relatively short time period between the information gathering phase and binding insurance coverage, the Company has determined that costs to fulfill contracts are not significant. Therefore, costs to fulfill a contract are expensed as incurred. The Company earns policy fee revenue for acting in its capacity as a managing general agent (“MGA”) on behalf of the Insurance Company Partner and fulfilling certain services including delivery of policy documents, processing payments and other administrative functions during the term of the insurance policy. Policy fee revenue is deferred and recognized over the life of the policy. These deferred amounts are recognized as contract liabilities, which is included as a component of accrued expenses and other current liabilities on the consolidated balance sheets. The Company earns installment fee revenue related to policy premiums paid on an installment basis for payment processing services performed on behalf of the Insurance Company Partner. The Company recognizes installment fee revenue in the period the services are performed.
Cash and Cash Equivalents	Cash Equivalents The Company considers all highly liquid short-term instruments with original maturities of three months or less to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash includes amounts that are legally restricted as to use or withdrawal. Restricted cash represents cash collected from customers that is payable to insurance companies and for which segregation of this cash is required by contract with the relevant insurance company providing coverage or by law within the state. The Company holds restricted cash specifically in its role as an MGA.
Premiums, Commissions and Fees Receivable, Net	Premiums, Commissions and Fees Receivable, Net In its capacity as an insurance agent or broker, the Company typically collects premiums from Clients, and after deducting its authorized commissions, remits the net premiums to the appropriate Insurance Company Partners. Accordingly, premiums receivable reflect these amounts due from Clients. In other circumstances, the Insurance Company Partners collect the premiums directly from Clients and remit the applicable commissions to the Company. Accordingly, commissions receivable reflect these amounts due from Insurance Company Partners. Fees receivable primarily represent amounts due from Clients of the Company’s services division. Premiums, commissions and fees receivable are reported net of allowances for estimated policy cancellations and doubtful accounts. The allowance for estimated policy cancellations was $2.2 million and $250,000 at December 31, 2019 and 2018 , respectively, which represents a reserve for future reversals in commission and fee revenues related to the potential cancellation of client insurance policies that were in force as of each year end. The allowance for estimated policy cancellations is established through a charge to revenues. The allowance for estimated policy cancellations is offset in part by a producer commissions chargeback of $1.2 million at December 31, 2019 . The producer commissions chargeback is established through a charge to producer commissions expense and is netted against producer commissions payable on the balance sheets. The allowance for doubtful accounts was $50,000 and $40,000 at December 31, 2019 and 2018 , respectively. The allowance for doubtful accounts is based on management’s estimate of the amount of receivables that will actually be collected. Accounts are charged to the allowance as they are deemed uncollectible based upon a periodic review of the accounts.
Property and Equipment, Net	Property and Equipment, Net Property and equipment is stated at cost. For financial reporting purposes, depreciation of property and equipment is calculated using the straight-line method over the estimated useful lives of the assets as follows: Years Building 39 Leasehold improvements 3 - 10 Furniture 5 - 7 Office and computer equipment 3 - 7 Vehicle 5 Website development 7 Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful life or the reasonably assured lease term at inception of the lease. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts. The difference between the net book value of the assets and proceeds from disposal is recognized as a gain or loss on disposal, which is included in other income (expense), net in the consolidated statements of comprehensive income (loss). Routine maintenance and repairs are charged to expense as incurred, while costs of improvements and renewals are capitalized. Property and equipment is evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. An asset is considered to be impaired when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposition does not exceed its carrying amount. The amount of the impairment loss, if any, is measured as the amount by which the carrying value of the asset exceeds its fair value.
Intangible Assets, Net and Goodwill	Intangible Assets, Net and Goodwill The majority of the Company’s intangible assets are acquired in connection with strategic acquisitions made by the Company (“Partnerships”). Intangible assets identified in a Partnership are recorded at fair value on the acquisition date. The excess of the purchase price in a business combination over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed is assigned to goodwill. Intangible assets are stated at cost, less accumulated amortization, and consist of purchased customer accounts, carrier relationships, software and trade names acquired in connection with business combinations. Purchased customer accounts, carrier relationships and trade names are being amortized based on a pattern of economic benefit over an estimated life of five to twenty years. Purchased customer accounts primarily consist of records and files that contain information about insurance policies and the related Clients that are essential to policy renewals. Carrier relationships consist of relationships with Insurance Company Partners that were not previously established. Trade names consist of acquired business names with potential customer base recognition. Intangible assets also include software, which is amortized on the straight-line basis over an estimated useful life of three to five years. We review our definite-lived intangible assets and other long-lived assets for impairment whenever an event occurs that indicates the carrying amount of an asset may not be recoverable. No impairment was recorded for the years ended December 31, 2019 and 2018 . Goodwill is subject to an impairment assessment on an annual basis or whenever indicators of impairment are present. The Company performs a qualitative assessment to determine whether a quantitative impairment test is necessary. In a quantitative assessment, 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 carrying value of a reporting unit is greater than the fair value, an impairment charge is recorded for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the amount of goodwill of the reporting unit.
Deferred Financing Costs, Net	Deferred Financing Costs, Net Deferred financing costs consist of origination fees and debt issuance costs related to obtaining credit facilities. The Company has recorded these costs as an asset on the consolidated balance sheets in accordance with ASC Topic 835-30, Interest. Deferred financing costs are included in other assets on the consolidated balance sheets. Deferred financing costs were approximately $1.8 million and $861,000 , net of accumulated amortization of approximately $470,000 and $270,000 at December 31, 2019 and 2018 , respectively. Such costs are amortized using the effective interest method over the terms of the respective debt. Amortization of deferred financing costs was approximately $1.3 million and $118,000 for the years ended December 31, 2019 and 2018 , respectively, and is included in interest expense, net in the accompanying consolidated statements of comprehensive income (loss).
Contingent Earnout Liabilities	Contingent Earnout Liabilities The Company accounts for contingent consideration relating to business combinations as either contingently returnable consideration or a contingent earnout liability and a decrease (increase) to goodwill at the date of the acquisition and continually remeasures the asset or liability at each balance sheet date by recording changes in the fair value through change in fair value of contingent consideration in the consolidated statements of comprehensive income (loss). The ultimate settlement of contingently returnable consideration and contingent earnout liabilities relating to business combinations may be for amounts that are materially different from the amounts initially recorded and may cause volatility in the Company’s results of operations. The Company accounts for contingent consideration relating to asset acquisitions as a contingent earnout liability and an increase to the cost of the acquired assets on a relative fair value basis at the date of the acquisition. Once recognized, the contingent earnout liability is not derecognized until the contingency is resolved and the consideration is issued or becomes issuable. If the amount initially recognized as a liability exceeds the fair value of the contingent consideration issued or issuable, the entity recognizes that amount as a reduction of the cost of the asset acquisition. The ultimate settlement of contingent earnout liabilities relating to asset acquisitions may be for amounts that are materially different from the amounts initially recorded. The Company determines the fair value of contingently returnable consideration and contingent earnout liabilities based on future cash flow projections under various potential scenarios and weighs the probability of these outcomes as discussed further in Note 23 .
Advisor Incentive Liabilities	Advisor Incentive Liabilities During the last several years, the Company entered into advisor incentive agreements with several of its producers (“Risk Advisors”) to incentivize them to stay with the Company, grow their book of business, and earn the role of partner as a member of the Company. The incentive rights had a deposit buy-in requirement payable in the form of payroll withholding or other cash payments for which the Company recorded an advisor incentive liability. The incentive rights could be converted to LLC Units after the achievement of certain milestones, subject to approval at the discretion of management. The units were convertible for a proportionate share of the fair value of BRP or one of its subsidiaries. The redemption price was not affected by changes in the units’ fair value. An increase in fair value of units would reduce the number of units issued to satisfy the obligation. The agreement does not limit the amount the Company could be required to pay or the number of units required to be issued. The Company accounts for the advisor incentive awards as liability-classified share-based payment awards under ASC 718, Compensation - Stock Compensation (“Topic 718”). Risk Advisors were deemed probable of meeting the performance condition after having achieved the first milestone related to their advisor incentive agreements. Thereafter, the Company estimated the fair value of the grants and recorded compensation expense and an advisor incentive liability each reporting period through the settlement date. Advisor incentive liabilities are included in other liabilities on the consolidated balance sheet and compensation expense for advisor incentive liabilities is included in commissions, employee compensation and benefits in the consolidated statements of comprehensive income (loss). Advisor incentive liabilities were classified as non-current liabilities as they were not expected to be settled in the near term at December 31, 2019 and 2018.
Participation Unit Ownership Plan Liabilities	Participation Unit Ownership Plan Liabilities During 2016, the Company established the Participation Unit Ownership Plan (the “Participation Plan”), which offered certain Colleagues additional incentives to promote success. The Participation Plan permitted the grant of up to 100,000 participation units, to be settled in cash only. Participation units vested on the fifth anniversary of the date of the grant unless a qualifying event occurs, as outlined in the Participation Plan agreement. Refer to Note 13 for further discussion of the Company’s participation plan liabilities, which were settled in connection with the Reorganization Transactions. The Company accounts for the issuance of participation units in accordance with ASC Topic 710, Compensation , which requires these units to be treated as liabilities on the consolidated balance sheets. At the grant date and at the end of each subsequent reporting period, the Company estimates the ultimate payout of the participation units. The Company records compensation expense and liability based on this estimated payout and for the portion of the vesting period that has been completed. Participation unit ownership plan liabilities are included in other liabilities on the consolidated balance sheet and Compensation expense for participation units is included in commissions, employee compensation and benefits expense in the consolidated statements of comprehensive income (loss).
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest ASC Topic 480, Distinguishing Liabilities from Equity (“Topic 480”) , requires noncontrolling interests that are redeemable for cash or other assets to be classified outside of permanent equity if they are redeemable (i) at a fixed or determinable price on a fixed or determinable date, (ii) at the option of the holder, or (iii) upon the occurrence of an event that is not solely within the control of the issuer. Prior to the Reorganization Transactions, the equity securities of certain of the Company’s noncontrolling interests contained an embedded put feature that was redeemable at the election of the interest holder. The Company had no control over whether the put option was exercised, and therefore, redemption was outside the Company’s control. As such, these equity securities were recorded as redeemable noncontrolling interests, which were classified in mezzanine equity on the Company’s consolidated balance sheets at December 31, 2018. Redeemable noncontrolling interests are reported at estimated redemption value measured as the greater of estimated fair value at the end of each reporting period or the historical cost basis of the redeemable noncontrolling interest adjusted for cumulative earnings or loss allocations. The resulting increases or decreases to redemption value, if applicable, are recognized as adjustments to retained earnings. The accounts of the following joint ventures have been consolidated into the Company’s consolidated financial statements since their respective inceptions until the Reorganization Transactions. The noncontrolling ownership interests in the Company’s subsidiaries described below are presented as redeemable noncontrolling interest in the consolidated financial statements prior to the Reorganization Transactions. • In 2018, BRP Black Insurance, LLC (“Black”) was formed in order to acquire substantially all the assets and liabilities of Black Insurance and Financial Services, LLC from Christopher R. Black (“Chris Black”). Chris Black had a 40% ownership interest in Black prior to the Reorganization Transactions. • In 2018, BRP Insurance Intermediary Holdings, LLC (“BIH”) was formed in order to acquire 60% of the membership interests of AB Risk Specialist, LLC (“ABRS”), which owned a 100% membership interest in KB Risk Solutions, LLC (“KBRS”), from AB Risk Holdco, Inc. (“AB Holdco”). Additionally, immediately following BIH’s acquisition of the membership interests of ABRS, Emanuel Lauria was issued a 33.3% membership interest in KBRS. AB Holdco had a 40% ownership interest in ABRS prior to the Reorganization Transactions. • In 2018, Baldwin Krystyn Sherman Partners, LLC (“BKS”) acquired substantially all the assets and liabilities of Montoya Property & Casualty Insurance from Montoya and Associates, LLC (“Montoya & Associates”). Montoya & Associates had a 1.5% ownership interest in BKS prior to the Reorganization Transactions. • In 2019, BIH acquired 70% of the membership interests of Millennial Specialty Insurance, LLC from Millennial Specialty Holdco, LLC (“MSH”). MSH had a 30% ownership interest in Millennial Specialty Insurance, LLC prior to the Reorganization Transactions. • In 2019, BKS Financial Investments, LLC was formed to acquire substantially all the assets and liabilities of Fiduciary Partners Investment Consulting, LLC and BKS acquired substantially all the assets and liabilities of Fiduciary Partners Retirement Group, Inc. (“FPRG”) and Fiduciary Partners Group, LLC. FPRG had a 0.3% ownership interest in BKS prior to the Reorganization Transactions. • In 2019, BRP Foundation, LLC (“Foundation”) was formed in order to acquire substantially all the assets and liabilities of Foundation Insurance of Florida, LLC from its members (“Foundation Members”). The Foundation Members had a 20% ownership interest in Foundation prior to the Reorganization Transactions. In conjunction with the Reorganization Transactions as discussed in Note 3 , the Company executed its call rights for the majority of the redeemable noncontrolling ownership interests, which were converted into permanent equity through the issuance of Class B common stock and LLC Units. Refer to Note 15 for additional discussion of redeemable noncontrolling interest.
Redeemable Members' Capital	Redeemable Members ’ Capital Topic 480 requires common units that are redeemable for cash or other assets to be classified outside of permanent equity if they are redeemable (i) at a fixed or determinable price on a fixed or determinable date, (ii) at the option of the holder, or (iii) upon the occurrence of an event that is not solely within the control of the issuer. Prior to the Reorganization Transactions, the Voting Common Units of two minority holders contained certain put and call rights in conjunction with termination at the greater of fair value or a floor, as defined in the BRP’s amended and restated limited liability operating agreement (the “Operating Agreement”). The Company had no control over whether the put option was exercised, and therefore, redemption was outside the Company’s control. As such, these equity securities were recorded as redeemable members’ capital, which were classified in mezzanine equity on the Company’s consolidated balance sheets. In conjunction with the Reorganization Transactions as discussed in Note 3 , the Company executed its call rights for redeemable members’ capital ownership interests, which were converted into permanent equity through the issuance of Class B common stock and LLC Units. Refer to Note 15 for additional discussion of redeemable members’ capital.
Noncontrolling Interest	Noncontrolling Interest Noncontrolling interests are reported at historical cost basis adjusted for cumulative earnings or loss allocations and classified as a component of stockholders’/members’ equity (deficit) on the consolidated balance sheets. Noncontrolling interest as presented herein as of and for the year ended December 31, 2018 consists of the noncontrolling interest holdings of BRP. Noncontrolling interest as presented as of and for the year ended December 31, 2019 consists of the noncontrolling interest holdings of BRP Group subsequent to the Reorganization Transactions. The controlling interest holdings of BRP for the period from January 1, 2019 through October 27, 2019 have been reclassified to noncontrolling interest holdings of BRP Group for presentation of activity for the year ended December 31, 2019.
Income Taxes	Income Taxes BRP has been, and will continue to be, treated as a partnership for U.S. federal, state and local income tax purposes. As a partnership, BRP’s taxable income or loss is included in the taxable income of its members. Accordingly, no income tax expense was recorded for federal and state and local jurisdictions for periods prior to the Initial Public Offering. BRP Group is a taxable entity and in connection with the Initial Public Offering and the Reorganization Transactions completed on October 28, 2019 , the Company became a taxable entity. In addition, BRP Colleague Inc., a subsidiary of BRP Group, was formed as a C Corporation during 2017 and is a taxable entity. The Company accounts for income taxes pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. The Company and its subsidiaries follow ASC Topic 740, Income Taxes . A component of this standard prescribes a recognition and measurement threshold of uncertain tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. Management has evaluated the Company’s tax positions and concluded that the Company has taken no uncertain tax positions that require adjustment to the financial statements to comply with the provisions of this guidance. The Company does not expect any of its tax positions to change significantly in the near term.
Tax Receivable Agreement	Tax Receivable Agreement The Company’s purchase of BRP’s LLC Units concurrent with the Initial Public Offering, and the future exchanges of LLC Units from BRP’s LLC Members and the corresponding number of shares of Class B common stock for shares of Class A common stock, is expected to result in increases in its share of the tax basis of the tangible and intangible assets of BRP, which will increase the tax depreciation and amortization deductions that otherwise would not have been available to BRP Group. These increases in tax basis and tax depreciation and amortization deductions are expected to reduce the amount of cash taxes that BRP Group would otherwise be required to pay in the future. BRP Group has entered into a Tax Receivable Agreement, with the other members of BRP that requires it to pay them 85% of the amount of cash savings, if any, in U.S. federal, state, and local income tax that BRP Group actually realizes (or, under certain circumstances, is deemed to realize) as a result of the increases in tax basis in connection with exchanges by the recipients described above and certain other tax benefits attributable to payments under the Tax Receivable Agreement.
Share-based Compensation	Share-Based Compensation Share-based payments to employees and non-employee directors are measured based on the estimated grant-date fair value. The grant-date fair value of restricted stock awards is equal to the market value of BRP Group’s Class A common stock on the date of grant. The Company recognizes share-based compensation expense over the requisite service period for awards expected to ultimately vest. The Company recognizes forfeitures as they occur.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying values of the Company’s financial assets and liabilities, including cash and cash equivalents, premiums, commissions and fees receivable, premiums payable to insurance companies and accrued expenses and other current liabilities, approximate their fair values because of the short maturity and liquidity of those instruments.
Concentrations	Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents. The Company manages this risk using high credit worthy financial institutions. Interest-bearing accounts and noninterest-bearing accounts are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 . Deposits exceed amounts insured by the FDIC. The Company has not experienced any losses from its deposits. For the year ended December 31, 2019 , two Insurance Company Partners accounted for approximately 14% and 10% of the Company’s total core commissions.

Schedule of Business Acquisitions	The table below provides a summary of the total consideration and the estimated purchase price allocations made for each of the business acquisitions that became effective during the year ended December 31, 2019 . Due to the complexity of valuing the consideration paid and the purchase price allocation and the timing of these activities, certain amounts included in the consolidated financial statements may be provisional and subject to additional adjustments within the measurement period as permitted by Topic 805. The Company recorded measurement period adjustments for the Lykes and MSI Partnerships, which are reflected in the table below. Any measurement period adjustments related to prior period business combinations have been reflected as current period adjustments for the year ended December 31, 2019 in accordance with Topic 805.

The Lykes adjustment resulted in an increase to net assets before goodwill and a reduction to goodwill of $2.7 million . The MSI adjustment resulted in an increase to intangible assets and a reduction to goodwill of $3.6 million .
