Purchase price adjustments & the Locked Box — how the gap between LOI and closing gets reconciled.

The PPA philosophy is accounting precision over deal certainty. The Locked Box philosophy is the reverse — deal certainty over accounting precision. Sellers should know both because the choice between them has six-figure implications and because PPAs are the single most common source of post-closing conflict.

§ 01 · Working Capital AdjustmentsThe primary PPA mechanism.

Working capital is the most common PPA. It measures the agency's operating liquidity — its ability to pay bills and staff on Day 1 after the sale. The formula: Net Working Capital = (Operating Cash + Accounts Receivable) − (Accounts Payable + Accrued Expenses).

The critical insurance-agency rule: exclude fiduciary funds (premiums held in trust for carriers) from the NWC calculation. These funds belong to the carriers and policyholders, not the agency. Including them in NWC is one of the most common errors and one of the most costly.

Both parties agree on a Target NWC during negotiations — typically a 12-month trailing average to normalize seasonal fluctuations. That target becomes the benchmark against which the closing balance sheet is measured. The true-up runs 60–90 days post-close: if actual NWC is lower than the target, the seller owes the buyer the difference dollar-for-dollar; if higher, the buyer pays the seller the excess.

The seasonality trap. If the agency receives large contingency bonuses in March, cash spikes. Setting the Target NWC using March numbers and closing in October produces a massive apparent deficit. Always set the target on a 12-month average, never on a single peak month.

§ 02 · Other PPA flavorsAR adjustments and policy-portfolio adjustments.

Outstanding commissions and client payments are significant agency assets. Buyers are concerned about collectability. The deal may include a collection guarantee based on an assumed collection rate agreed during diligence. If the actual collection rate post-closing falls below the assumption (bad debt), the seller compensates the buyer for the shortfall. Receivables aged over 90 days are often excluded from value entirely as presumed bad debt. The contract should specify assumed collection rates by aging bucket to eliminate subjectivity.

The policy portfolio functions as agency inventory. Its value fluctuates daily through new business, renewals, and cancellations. Buyers assess the portfolio on the closing date — if book value has dropped (a major client cancelled), the price adjusts down; if the portfolio has grown significantly, the seller may negotiate a price increase. This protects both parties from the natural volatility of an active book.

§ 03 · Avoiding PPA disputesThe four dispute-avoidance tools.

Schedule of Accounting Policies (the rulebook). Include a detailed schedule specifying exactly how every line item is treated. "Calculated in accordance with GAAP" is insufficient — GAAP involves judgment, and a buyer's interpretation of "Accrued Expenses" or "Bad Debt" may differ from the seller's. The seller's posture: fight for "Consistent with Past Practices" as the standard. This forces the buyer to use the same accounting methods that generated the Target NWC.

Sample Calculation (the map). Attach an actual spreadsheet to the Purchase Agreement as an Exhibit, calculating a hypothetical NWC number using the most recent balance sheet. If a dispute arises, both parties point to this spreadsheet as the authoritative methodology.

Accounting Arbitration (the referee). Appoint a neutral CPA firm — the Independent Accountant — to resolve disputed calculations. This is significantly faster and cheaper than full legal arbitration. The Independent Accountant rules only on specific financial items, not legal questions.

Agreed Assumed Rates. Specify binary rules for subjective items (receivable aging thresholds, for example) to eliminate post-closing arguments about whether specific invoices are "collectible."

The dispute-resolution timeline runs: 30 days for the seller to review the buyer's final calculation and file specific objections, followed by a 15-day mandatory negotiation period before escalation to the Independent Accountant.

§ 04 · The Locked BoxThe fixed-price alternative.

The Locked Box fixes the purchase price on a historical balance-sheet date, eliminating post-closing adjustments entirely. Mechanically: buyer and seller agree on a historical date (e.g., December 31st) — the Locked Box Date. The price is calculated based on the financials as of that date. No subsequent adjustment occurs. From the Box Date forward, economic exposure shifts to the buyer, even though the seller still legally controls the business until closing.

For the seller: no post-closing true-up. The exact proceeds are known at signing. No 60–90 day wait for a final calculation. No risk of buyer manipulation of closing-date accounting.

The trade-off is leakage. Because the buyer effectively owns the economic value from the Box Date, the seller must not extract value before physical transfer. Actual leakage — special dividends, unscheduled bonuses, asset transfers to related parties — is prohibited and triggers dollar-for-dollar payback. Permitted leakage — regular payroll at existing rates, rent, ordinary expenses, scheduled tax distributions — is explicitly enumerated in the contract.

Sophisticated sellers negotiate a Value Accrual Ticker — a daily interest rate (typically 3–5% per annum) on the equity value to compensate the seller for cash generated during the gap between Box Date and Closing. Without it, the buyer captures Box-Date-to-close earnings while the seller waits to get paid.

§ 05 · When to choose whichThe deal-breaker conditions.

PPA fits when the seller's books are less sophisticated, the buyer has strong accounting resources, both parties accept uncertainty in exchange for precision, and NWC fluctuates predictably. Locked Box fits when the seller's financials are impeccable (audited or audit-quality), the transaction is a competitive auction with multiple bidders, the seller prioritizes price certainty, and the gap between Box Date and closing is short and predictable.

The Locked Box deal-breaker: if the seller's books are messy or lack audit-quality detail, buyers will refuse the Locked Box because they lose all post-closing protection. Financial discipline is what unlocks the option.
