Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	Business and Basis of Presentation BRP Group, Inc. (“BRP Group”) was incorporated in the state of Delaware on July 1, 2019. 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 Operating Groups, including Middle Market, Specialty, MainStreet, and Medicare, which are discussed in more detail in Note 15. The term the “Company” refers to BRP Group and its consolidated subsidiaries. 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 Baldwin Risk Partners, LLC (“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 consolidates BRP in its consolidated financial statements, resulting in a noncontrolling interest related to the membership interests of BRP (the “LLC Units”) held by BRP’s LLC members in its consolidated financial statements. The Company has prepared these consolidated financial statements in accordance with Accounting Standards Codification (“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 4 for additional information regarding the Company’s variable interest entities. Topic 810 also requires that the equity of a noncontrolling interest shall be reported on the condensed consolidated balance sheets within total equity of the Company. Certain redeemable noncontrolling interests are reported on the condensed 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. Public Equity Offering On September 17, 2021, the Company completed a public offering of 9,200,000 shares of its Class A common stock, including 1,200,000 shares sold pursuant to the underwriters’ over-allotment option. The shares were sold at an offering price of $30.50 per share for net proceeds of approximately $269.4 million after deducting underwriting discounts and commissions of $11.2 million. The Company used such proceeds to purchase 9,200,000 LLC Units. The Company also paid offering expenses of $1.1 million. Unaudited Interim Financial Reporting The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the SEC regarding interim financial reporting. Accordingly, they do not include all the information and related notes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments, consisting of recurring accruals, considered necessary for fair statement have been included. The accompanying balance sheet for the year ended December 31, 2020 was derived from audited financial statements, but does not include all disclosures required by GAAP. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 11, 2021. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the 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; the determination of fair value in relation to business combinations and purchase price allocation; impairment of long-lived assets including goodwill; valuation of the Tax Receivable Agreement liability and income taxes; and share-based compensation. Recent Accounting Pronouncements As an emerging growth company, the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits the Company an extended transition period for complying with new or revised accounting standards affecting public companies. The Company 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 elected the extended transition period for the adoption of the Accounting Standards Updates (“ASUs”) below. The Company has determined that it will cease to be an emerging growth company as of December 31, 2021, and therefore, will need to comply with the public company timeline on that date. 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, provided interpretation of and transition relief for the guidance issued in ASU 2016-02 and extended the adoption date for nonpublic business entities. This guidance will be effective for the Company on December 31, 2021 in conjunction with its loss of emerging growth company status (discussed above). The Company will adopt ASU 2016-02 using the modified retrospective approach as of January 1, 2021. Although the Company is currently evaluating the full effect that the adoption of ASU 2016-02 will have on its consolidated financial statements, it expects to recognize significant right-of-use assets and lease liabilities, resulting in an increase to its total assets and total liabilities. 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, provided interpretation of and transition relief for, the guidance issued in ASU 2016-13 and extended the adoption date for nonpublic business entities. This guidance will be effective for the Company on December 31, 2021 in conjunction with its loss of emerging growth company status (discussed above).
