Insurance Agency Book of Business Diligence and Retention Earnouts

1. Book of Business Valuation Fundamentals

Valuing an insurance agency's book of business is the foundational step in any acquisition. Unlike most professional service businesses where revenue is generated by discrete projects, an insurance agency generates revenue through recurring commissions tied to active policies. This recurring structure makes commission revenue the primary valuation anchor, and buyers typically apply a revenue multiple, an EBITDA multiple, or both depending on the size and complexity of the target.

Revenue multiples for insurance agency books typically fall between 1.5x and 3.5x of annualized commission revenue. The precise multiple reflects the quality of the revenue: high retention rates, diversified client bases, strong carrier relationships, and clean commercial P&C books command multiples toward the top of that range. Books with significant personal lines exposure, high client concentration, or heavy dependence on a single carrier sit at the lower end.

EBITDA multiples become more relevant when the target has meaningful scale, typically above $3 million in annual revenue, and a documented, stable cost structure. At that level, buyers apply multiples that reflect normalized profitability rather than top-line revenue, accounting for overhead, producer compensation arrangements, and technology expenses. The challenge is that smaller agencies often have owner-loaded compensation structures that require normalization before EBITDA is meaningful.

Buyers should resist the temptation to apply a single blended multiple to total revenue. A more rigorous approach segments the book into component streams: base commissions on renewals, base commissions on new business, contingent commissions, and fee-for-service income. Each stream carries different volatility and persistence characteristics. Renewal commissions are the most predictable and warrant the highest multiple. New business commissions are less predictable and should be discounted. Contingent commissions are the most volatile and are addressed in their own section of diligence.

The valuation conversation must also account for what is not in the commission revenue figure. Some agencies receive carrier-paid marketing allowances, premium finance referral fees, or administrative fees that appear in total revenue but are not tied to the book and would not transfer with it. Buyers should request a detailed revenue reconciliation that separates book-related commissions from ancillary income streams before finalizing any multiple analysis.

Ultimately, the valuation multiple is a starting point. It gets refined through the full diligence process as retention data, concentration analysis, and producer contract reviews reveal the actual quality of the revenue. A book that initially screens at a 2.5x multiple may earn a downward adjustment to 1.8x once concentration risk and contract gaps are identified. Buyers who anchor to the headline multiple before completing diligence routinely overpay.

2. Revenue Composition: New Business vs. Renewals, Commission vs. Contingent, Direct vs. Wholesale

Understanding the composition of an insurance agency's revenue is as important as understanding its total size. The same $2 million in annual commissions can represent very different risk profiles depending on how that revenue is distributed across revenue types, business sources, and carrier relationships.

The renewal-versus-new-business split reveals the book's organic growth characteristics and its stability. A book where 85 to 90 percent of revenue comes from renewals is highly predictable. The commissions are tied to existing client relationships that have already demonstrated persistence through prior renewal cycles. A book where new business represents 30 to 40 percent of total revenue raises a different question: is that growth rate sustainable post-acquisition, or was it driven by the founder's personal relationships and production activity that will not transfer?

The commission-versus-contingent split is a volatility indicator. Base commissions are set by carrier commission schedules and are contractually established for a policy period. Contingent commissions are earned based on loss ratio and volume performance metrics that fluctuate annually. An agency where contingent income represents 20 percent or more of total revenue has a meaningful earnings component that can swing significantly from year to year based on factors outside management's control. Buyers should model scenarios where contingent income is zero to stress-test coverage of fixed costs and purchase price service.

The direct-versus-wholesale channel split identifies market access dependencies. Agencies that place business primarily through wholesale brokers and managing general agents are more market-flexible but capture less commission per dollar of premium than direct-appointed agencies. Wholesale-heavy books may also have weaker carrier relationships, which affects the buyer's ability to renegotiate appointment terms post-acquisition. Direct-appointed agencies with strong carrier relationships offer more stability but may have narrower market access for non-standard risks.

Buyers should also examine the distribution of revenue across carriers. A book where 60 percent of premium flows through a single carrier creates carrier concentration risk that compounds client concentration risk. If that carrier adjusts its commission schedule, exits a market, or declines to transfer the appointment to the acquiring entity, the buyer faces an immediate revenue disruption. A well-diversified book spreads premium across multiple carriers in each line of business, reducing dependence on any single carrier relationship.

The revenue composition analysis should be performed at the account level, not just in aggregate. Buyers should request a full account export that includes the carrier, line of business, premium, and commission for each policy in the book. This enables independent verification of the revenue composition and supports the concentration and retention analyses that follow.

3. Client Concentration Analysis: Top 10, 20, and 50 Accounts; Industry Concentration

Client concentration is one of the most significant risk factors in insurance agency acquisitions and one of the most frequently underweighted in initial negotiations. An agency can have strong aggregate retention numbers while simultaneously carrying dangerous exposure to a small number of large accounts that could depart for reasons unrelated to the book's overall quality.

The standard approach to concentration analysis examines revenue attributable to the top 10, top 20, and top 50 accounts, expressed both as absolute dollar figures and as percentages of total commission revenue. A single account representing more than 10 percent of total commissions is a material concentration concern that warrants specific pricing adjustment, earnout protection, or both. A top-10 concentration exceeding 40 percent is a structural risk that affects how the entire transaction should be designed.

Buyers should also analyze what would happen if any one of the top three or five accounts departed immediately after closing. This stress test should model the revenue impact, the EBITDA impact after considering variable costs tied to those accounts, and the effect on earnout payment feasibility if the acquisition includes a retention-based earnout. Sellers often resist this analysis because it highlights the fragility of high-value account relationships, but it is a necessary component of informed pricing.

Industry concentration is a parallel analysis that is often overlooked in favor of account-level concentration. A book where 60 percent of commercial P&C premium comes from construction accounts is exposed to systemic risk from construction market downturns, workers' compensation adverse development, or carrier capacity withdrawal from that class of business. Similarly, a book concentrated in hospitality, healthcare, or any other cyclically sensitive sector carries industry-specific risk that a diversified book does not.

Buyers should request a concentration report that categorizes accounts by SIC or NAICS code and calculates premium and commission exposure by industry category. This report, combined with the account-level concentration analysis, gives a complete picture of the book's risk distribution. Where industry concentration is significant, buyers should research whether the agency has relationships with multiple carriers willing to write that sector and whether those carrier relationships are transferable.

Geographic concentration is a third dimension that affects post-acquisition risk. An agency where the majority of accounts are located in a single metropolitan area or state is more exposed to regional economic conditions, regulatory changes affecting insurance rates in that state, and catastrophe-related disruptions that could trigger mass non-renewals. Buyers acquiring regionally concentrated books should confirm that the carrier appointments being transferred provide adequate capacity in the relevant geography.

4. Retention Rate Methodology: Gross vs. Net Retention, Measurement Periods

Retention rate is the single most consequential metric in insurance agency valuation, and it is also the metric most susceptible to presentation manipulation. Buyers who accept seller-reported retention rates without independently reconstructing the calculation are accepting a number that may not reflect actual post-acquisition attrition risk.

Gross retention measures the percentage of accounts that renewed in a given period, regardless of premium or commission changes on those accounts. Net retention adjusts for premium changes, measuring the percentage of revenue retained across the renewal base. Both metrics are useful, and both should be calculated. A book with 90 percent gross retention but 80 percent net retention is experiencing significant premium compression on renewing accounts, which may reflect competitive pressure, risk quality deterioration, or carrier market exit.

The measurement period matters as much as the method. Sellers often report retention for the most recent year, which may be unrepresentative of longer-term trends. Buyers should request account-level renewal data for the prior three policy years and calculate annual retention independently for each year. A retention rate that has declined from 91 percent to 87 percent to 83 percent over three years tells a very different story than a static three-year average of 87 percent.

Account-level versus revenue-level retention is another methodological distinction with significant valuation implications. An agency might retain 88 percent of accounts by count but lose 75 percent of revenue if the departed accounts happened to be the largest in the book. Conversely, account-count retention might appear low while revenue retention is strong if the departed accounts were small. Buyers should calculate both metrics independently and understand the composition of the attrition cohort.

The denominator definition in the retention calculation is where most presentation manipulation occurs. Sellers may exclude accounts that were non-renewed for underwriting reasons, accounts that were deliberately culled for profitability, and accounts lost during a period of staff turnover. Some exclusions are legitimate; others are not. Buyers should define the denominator contractually in the letter of intent and confirm that the seller's historical retention reporting used the same definition being applied to the earnout baseline.

Finally, buyers should compare the agency's retention rates to published benchmarks for the relevant lines of business and geographic markets. Insurance industry trade associations publish annual benchmarking data on retention by line and region. An agency claiming above-benchmark retention without a clear structural explanation, such as a dominant niche, long-tenured producers, or proprietary market access, warrants closer scrutiny of the underlying account data.

5. Commission Rate Tier Diligence: Carrier Commission Schedules and Override Structures

Commission rates are not fixed or permanent. Carriers adjust commission schedules annually, and the rates an agency earns today may not be the rates it earns after a change of ownership. Buyers who model forward revenue based on current commission rates without investigating the contractual basis for those rates are building on an assumption that may not survive closing.

Most carriers publish tiered commission schedules that reward agencies for volume, profitability, and growth. An agency that has reached a higher commission tier based on its current premium volume may fall to a lower tier if the buyer's combined entity cannot maintain that volume on the relevant carrier. Similarly, carriers sometimes restructure commission schedules in connection with change-of-ownership events, adjusting the acquiring entity to a base tier until a new performance track record is established.

Override arrangements and contingent commission agreements are distinct from base commission schedules and require separate review. Override commissions are typically paid in addition to base commissions when an agency achieves specific volume or profitability thresholds. These arrangements are documented in separate agreements that may or may not be automatically assigned to the buyer in an asset purchase. Buyers should identify every override arrangement in the target's carrier portfolio and confirm assignment eligibility with each carrier before closing.

The commission tier analysis should include a projection of where the combined entity will fall on each carrier's schedule post-acquisition. If the buyer's existing book and the target's book are placed with the same carriers, the combined volume may allow the buyer to maintain or improve tier positioning. If the books use different carrier panels, the buyer may not receive credit for the target's volume history and must negotiate the transition period arrangement directly with each carrier.

Buyers should also review the carrier agreements for provisions that affect commission rates in connection with mergers and acquisitions. Some agreements include change-of-control provisions that give the carrier the right to renegotiate terms or terminate the appointment upon a transfer. Identifying these provisions before signing a purchase agreement allows the buyer to negotiate appointment continuity representations from the seller or build appropriate contingencies into the deal structure.

Finally, the commission rate analysis should document the net commission rate for each major line of business after subtracting any producer splits. The gross commission rate paid by the carrier is less relevant than the net commission retained by the agency after producer compensation. Where producers receive high splits on accounts they originated, the buyer's effective commission rate on those accounts is lower than the carrier schedule suggests.

6. Client Cancellation Patterns and Early Warning Signals

Retention rate is a lagging indicator. By the time an attrition problem appears in the annual retention calculation, the accounts have already left. Buyers who want to assess the forward trajectory of retention need to analyze cancellation patterns and identify the early warning signals that precede account departure.

The most informative cancellation analysis examines the timing, cause, and account profile of every account that departed in the prior three years. Timing patterns reveal whether attrition is clustered around specific renewal periods, suggesting systematic service failures or competitive pricing pressure at particular policy types. Cause codes, where the agency tracks them, identify whether departures were price-driven, service-driven, or triggered by external factors such as the client's sale or closure of its business.

Account profile analysis of departed clients is particularly revealing. If the accounts that left skew toward larger accounts, accounts in a specific industry, or accounts with a particular producer, the buyer has identified a concentration within the attrition cohort that the aggregate retention rate does not capture. A pattern of mid-market commercial accounts departing for direct writer relationships, for example, suggests a competitive vulnerability that will persist post-acquisition.

Mid-term cancellations are a separate and more urgent signal than non-renewals at expiration. An account that cancels mid-term is experiencing either a severe service failure, a carrier dispute, or a fundamental change in its operations. Buyers should request mid-term cancellation data separately from expiration non-renewals and examine whether mid-term cancellation rates have been increasing. A rising mid-term cancellation rate is one of the clearest indicators of a book in operational distress.

Customer service escalation logs, complaint data, and carrier loss run requests are additional data sources that can surface early warning signals not visible in the commission reporting. Buyers with access to the agency management system should request exports of service activity, complaint tickets, and escalation records for the prior 24 months. An unusual spike in service escalations in the 12 months prior to the sale is worth understanding before closing.

Finally, buyers should ask sellers directly about any accounts the seller knows to be at risk of non-renewal at their next expiration date. This question puts the seller on notice that a disclosure obligation exists and creates a contractual record. Accounts that the seller identified as at-risk but failed to disclose can create post-closing indemnification claims if those accounts depart within the earnout measurement period.

7. Contingent Commission and Profit-Sharing Agreement Review

Contingent commissions and profit-sharing arrangements represent a meaningful portion of revenue at many insurance agencies, and they are among the most misunderstood components of an agency's financial profile. The income appears on the financial statements alongside base commissions, but its persistence and transferability are fundamentally different.

Profit-sharing agreements are typically documented in carrier-specific addenda to the agency's appointment agreement. These arrangements pay an additional commission, often ranging from 1 to 5 percent of premium, based on the agency's loss ratio performance, premium volume growth, and sometimes a combination of the two. The formulas vary significantly by carrier, and the payment is typically calculated once annually based on the prior year's performance.

Buyers must request copies of every profit-sharing or contingent commission agreement in the target's carrier portfolio. These documents specify the performance thresholds, the payment formula, the measurement period, and importantly, whether the agreement is assignable in connection with an asset purchase. Some carriers treat profit-sharing agreements as personal to the selling agency and require renegotiation upon a change of ownership. If the buyer assumes the contingent income in its valuation model without confirming transferability, the error can result in a material revenue shortfall in year one.

The performance threshold review is equally important. An agency that barely cleared a carrier's profit-sharing threshold in the most recent measurement year may not clear it next year, particularly if the book experiences post-closing attrition that reduces premium volume or if a few large claims push the loss ratio above the threshold. Buyers should model each contingent commission arrangement under scenarios where the relevant threshold is not met and calculate the revenue impact.

Buyers should also examine the loss ratio trends for each carrier relationship over three to five years. A carrier relationship where the loss ratio has been trending upward is at increasing risk of losing its profit-sharing payment and potentially triggering a carrier review of the agency's overall appointment. Conversely, a carrier relationship with consistently favorable loss ratios suggests a well-managed book that is likely to continue generating contingent income.

The timing of contingent commission payments creates a working capital consideration that buyers often overlook. Profit-sharing payments are typically made in the first quarter of the year following the measurement period, meaning that the first contingent payment a buyer receives may not arrive until 12 to 15 months after closing. Buyers should model cash flow accordingly and confirm that the purchase price and financing structure account for this timing gap.

8. Producer Book Ownership Contracts: Who Owns the Client Relationship

The question of who legally owns the client relationships in an insurance agency is one of the most consequential and most frequently underexamined issues in agency M&A. The seller may represent that it owns the entire book, but that representation is only as strong as the underlying producer agreements that establish ownership.

Producer employment and independent contractor agreements are the controlling documents. A well-drafted agency employment agreement includes an explicit provision stating that all client relationships developed during the producer's employment belong to the agency, not to the producer. These provisions are legally enforceable in most jurisdictions when properly drafted, and they give the buyer a clear contractual basis for protecting the book post-acquisition.

Many agencies, particularly those founded and operated by a single principal, have producer agreements that are silent on ownership or that were drafted decades ago before ownership provisions became standard. In these situations, the legal analysis becomes more complex. Courts in various states have reached different conclusions about implied book ownership, and the outcome depends on the specific facts of the producer relationship, the agency's operating practices, and state law governing insurance producer contracts.

Buyers should request and review every producer agreement for every producer who generates more than 5 percent of total commission revenue. The review should confirm whether an ownership provision exists, whether it is enforceable under applicable state law, whether the producer has executed any side letters or amendments that might undercut the primary agreement, and whether the producer is an employee or an independent contractor, as the analysis differs significantly between those classifications.

Where a key producer lacks an adequate ownership provision, the buyer has several options. The buyer can require the seller to obtain a signed acknowledgment from the producer confirming that client relationships belong to the agency as a condition to closing. The buyer can negotiate a retention agreement directly with the producer that includes ownership confirmation and post-closing non-solicitation obligations. Or the buyer can adjust the purchase price to reflect the ownership uncertainty as a risk factor in the valuation.

The producer ownership analysis intersects directly with the non-solicitation analysis discussed in the following section. A producer who lacks a binding ownership acknowledgment and also lacks an enforceable non-solicitation covenant represents a dual exposure: the producer may claim ownership of a portion of the book and simultaneously have the right to solicit those clients after departure. This combination is a significant post-closing attrition risk that must be addressed before signing.

9. Non-Solicit and Non-Piracy Enforcement in Book Retention

Non-solicitation and non-piracy covenants are the legal mechanisms that protect the buyer's investment in the book of business after closing. Without enforceable covenants, a departing producer or the selling principal can immediately approach former clients and direct that business away from the acquiring entity. The economic damage from this scenario can exceed the entire earnout payment the seller expected to receive.

Non-solicitation covenants prohibit a departing producer or seller from proactively approaching clients for a defined period after departure or closing. Non-piracy covenants go further and prohibit acceptance of business from former clients even if the client initiates contact. The distinction matters because courts in some states will enforce non-piracy provisions while declining to enforce broader non-compete restrictions. Buyers should confirm which covenant type is enforceable under applicable state law and draft accordingly.

The geographic scope and duration of non-solicitation covenants in insurance agency contexts are subject to state-specific reasonableness standards. Courts generally analyze whether the scope is reasonably necessary to protect the buyer's legitimate business interests, which in an insurance agency context is typically defined as the specific client relationships included in the transferred book. A narrowly tailored covenant that prohibits solicitation of transferred clients for two to three years in the relevant operating territory is more likely to be enforced than an overbroad restriction.

The seller's personal non-solicitation covenant in the purchase agreement is distinct from and in addition to any producer-level non-solicitation obligations. In an owner-operated agency where the founder had personal relationships with key accounts, the seller's personal covenant is particularly important. Buyers should negotiate a seller non-solicitation that covers the full earnout period plus 12 to 24 months, ensuring that the seller remains aligned with book retention through the entire measurement period.

Enforcement mechanisms are as important as the covenant terms. A non-solicitation provision that relies exclusively on a damages remedy provides limited practical protection because proving damages from client solicitation is expensive and uncertain. Buyers should negotiate for injunctive relief provisions that allow the buyer to seek an immediate court order stopping solicitation activity without being required to prove actual damages. The availability of injunctive relief as a contractual remedy is recognized in most jurisdictions and significantly increases the deterrent value of the non-solicitation covenant.

Finally, buyers should request information about any prior non-solicitation disputes the target agency has been involved in, either as plaintiff or defendant. A pattern of disputes suggests either aggressive producer competition in the relevant market or weak internal contract practices that allowed the disputes to arise. Either pattern provides useful context for evaluating the legal risk environment the buyer is entering.

10. Cross-Sell Penetration and Account Rounding Metrics

Cross-sell penetration measures the degree to which existing clients purchase multiple lines of coverage through the same agency. A client that places commercial general liability, commercial auto, and umbrella coverage through one agency is more deeply integrated with that relationship and statistically less likely to move its business than a client that places only a single line. Cross-sell penetration is therefore a retention predictor as well as a revenue enhancement metric.

Buyers should request account-level data that shows the number of policies per client, the lines represented, and the total premium and commission per account across all lines. This data supports two analyses: it identifies the current cross-sell penetration rate across the book, and it identifies the accounts where additional lines could be placed post-acquisition, representing an organic growth opportunity that should be quantified in the investment thesis.

Account rounding is the practice of filling gaps in a client's coverage program by placing lines that the client currently buys elsewhere. An agency that has built a reputation for comprehensive account rounding creates stickier client relationships than an agency that serves as a monoline or limited-line producer. The diligence question is whether the current rounding activity is systematic or opportunistic, and whether the producers responsible for rounding will remain with the business post-acquisition.

The cross-sell analysis should distinguish between commercial and personal lines activity. Commercial accounts with multiple lines represent a fundamentally different relationship than personal lines clients with bundled home and auto. Commercial multi-line accounts are typically driven by the producer relationship and the agency's market access. Personal lines bundled accounts are often driven by carrier pricing incentives and are more susceptible to disruption by direct writer competition.

Buyers should also examine cross-sell performance trends over the prior three years. An agency where cross-sell penetration has been increasing is demonstrating a systematic approach to account development. An agency where penetration has been flat or declining despite a stable account base may have stalled its growth strategy or may be losing lines to competitor agencies. The trend line is more informative than the current penetration rate.

The cross-sell data also provides insight into the agency's carrier breadth. An agency that effectively rounds commercial accounts across multiple lines must have carrier appointments across multiple lines. Confirming that those appointments are transferable and that the buyer's entity meets each carrier's eligibility requirements for each line is a diligence step that directly affects the buyer's ability to maintain and grow the cross-sell revenue stream post-acquisition.

11. Book Segmentation: Personal Lines, Commercial P&C, Benefits, Specialty

An insurance agency's book of business is rarely homogeneous. Most established agencies carry clients across multiple lines of business, and each segment has distinct valuation characteristics, retention dynamics, and post-acquisition integration considerations. Buyers who analyze the book only in aggregate miss the segment-level risks that can significantly affect post-closing performance.

Personal lines, including personal auto, homeowners, and umbrella, typically command lower valuation multiples than commercial lines due to higher price sensitivity, lower switching costs, and more direct competition from carrier-direct distribution channels. Personal lines books are also more susceptible to disruption from carrier market exits, rate increases, and catastrophe-driven underwriting restrictions in certain geographies. Buyers should evaluate whether the personal lines segment is a strategic fit or a book element to be managed for runoff.

Commercial property and casualty is typically the most valuable segment in an agency book. Commercial P&C relationships are driven by the producer's advisory role, market access, and claims advocacy, all of which create switching costs that personal lines relationships do not have. Commercial P&C clients with complex risk profiles are particularly sticky because finding an alternative producer with equivalent market access and technical expertise requires significant effort. The diligence focus on this segment should prioritize retention rate, producer relationships, and carrier access.

Employee benefits, including group health, dental, vision, and life, is a segment with distinctive characteristics. Benefits accounts are often won and retained on the basis of plan design expertise and carrier negotiations during the annual renewal cycle. Benefits relationships are strong when the producer is actively engaged in plan management throughout the year, and weaker when the relationship is primarily transactional. Buyers should assess whether the benefits book has active service engagement or primarily renewal-season contact, as the former is far more retentive.

Specialty lines, including professional liability, management liability, cyber, and environmental coverage, represent a growing segment in many agency books. Specialty lines typically carry higher commissions than standard commercial P&C and often reflect the producer's technical expertise in a specific vertical. The diligence question for specialty lines is whether the expertise that created the book resides in the agency as an institutional capability or in a specific producer whose departure would compromise the agency's ability to service and retain the accounts.

The segmentation analysis should conclude with a segment-level revenue and retention summary that applies differentiated assumptions to each segment. A blended retention assumption applied uniformly across personal lines, commercial P&C, and benefits will systematically overstate some segments and understate others. Differentiated assumptions produce a more accurate revenue model and support more precise earnout structure design.

12. Retention-Based Earnout Structure Design and Measurement Mechanics

Earnout provisions tied to book retention are the standard mechanism for aligning seller and buyer interests in insurance agency acquisitions. A well-structured earnout protects the buyer against post-closing attrition while giving the seller a path to full price realization if the book performs as represented. A poorly structured earnout creates disputes, misaligned incentives, and litigation risk that can eliminate the value the acquisition was intended to create.

The foundational decision in earnout design is choosing the measurement metric. Commission revenue is the most common metric, but it must be defined with precision. The parties must specify whether revenue is measured on a written or earned basis, whether it includes or excludes contingent commissions, how mid-term policy changes affecting premium are handled, and what happens to accounts that are cross-sold additional lines during the earnout period. Each of these definitional choices affects the earnout calculation in ways that can generate meaningful disputes if left to interpretation.

The earnout period duration should reflect the book's renewal cycle and the realistic timeframe over which post-closing attrition risk is concentrated. Most post-acquisition attrition occurs in the first two renewal cycles, making a 24 to 36 month earnout period appropriate for most commercial P&C books. Personal lines books may warrant a shorter earnout given faster attrition cycles. Benefits books tied to annual employer renewal cycles typically use a two-year measurement period aligned with the renewal calendar.

Payment structure determines how the earnout amount is calculated as a function of retention performance. A threshold-based earnout pays the full earnout amount if retention exceeds a defined floor, and nothing below it. A sliding scale earnout pays a proportional amount based on the degree to which actual retention compares to the baseline. The sliding scale approach is generally preferable because it reduces the probability of cliff-edge disputes and provides partial compensation for partial performance.

Attribution rules are the most contentious element of earnout design and must be resolved in the purchase agreement before signing. Attribution questions arise when an account departs for reasons that the parties might characterize differently: the seller may argue that a departure was caused by the buyer's post-closing integration decisions, while the buyer may argue that the departure reflects pre-existing attrition risk. The agreement should specify which party bears the risk for attrition caused by carrier appointment changes, integration-related service disruptions, producer departures, and industry-wide market conditions.

Operational covenants during the earnout period are the buyer's primary tool for protecting the measurement baseline. The purchase agreement should require the buyer to maintain the agency management system, preserve carrier appointments, retain key producers at specified compensation levels, and avoid material changes to the service model that could trigger attrition. These covenants protect the seller against buyer actions that harm the earnout baseline, but they also constrain the buyer's operational flexibility. The negotiation of operational covenants is one of the most important and most time-consuming elements of insurance agency M&A transaction documentation.
