Seller Note
Definition
A seller note is deferred purchase-price financing provided by the seller of a business, usually repaid over time from the acquired company's cash flow.
Why it matters
Seller notes can bridge valuation and financing gaps in search-fund and small-business acquisitions, but subordination, amortization, covenants, and seller alignment matter.
Common misconceptions
- •Seller financing is not free equity; it is debt or deferred consideration with negotiated priority.
- •A large seller note can signal alignment, financing constraint, or valuation disagreement depending on context.
- •A contractual claim on an acquired business is not equivalent to cash because senior debt, covenants, working-capital needs, subordination, and operating performance determine payment capacity.
- •Alignment with the searcher does not remove conflicts around valuation, add-on acquisitions, compensation, refinancing, distributions, amendments, or the timing of an exit.
Technical details
Terms
Key provisions include principal amount, interest, amortization, maturity, payment-in-kind options, subordination, security, covenants, default rights, and change-of-control treatment.
Acquisition Use
Search funds use seller notes to reduce third-party leverage, retain seller confidence, and close valuation gaps when bank debt and investor equity are insufficient.
Acquisition capitalization, payment capacity, and control
Analyze Seller Note inside the full acquisition capitalization rather than as an isolated security. Reconcile purchase price, working-capital adjustment, transaction fees, senior and junior debt, seller financing, investor equity, searcher equity, rollover ownership, option pools, earnouts, and post-close liquidity. Confirm legal priority and whether later debt can prime or structurally subordinate the position.
Build payment capacity from operating cash flow after taxes, maintenance capital expenditure, working capital, senior debt service, covenants, and required reserves. A business producing $3 million of EBITDA may have far less cash available if customer concentration, inventory growth, equipment replacement, or floating-rate leverage absorbs liquidity. Stress revenue loss, margin compression, delayed integration, and refinancing.
Review consent, information, amendment, default, acceleration, board, transfer, and exit rights. Track actual results against the acquisition model, debt covenants, management hiring, add-on spending, distributions, and remaining liquidity. Searcher incentives should be modeled across downside, base, and exit cases, including step-ups or vesting that change ownership over time.
Investor relevance
Seller Note matters because specialty-asset investments usually depend on a narrow set of contractual rights, operational controls, and valuation assumptions rather than broad market liquidity. A public bond investor can often observe market price, trading volume, and issuer disclosures. A specialty-asset investor may have to rely on a PPM, an SPV agreement, a custody record, a royalty statement, a reserve report, a legal claim budget, an appraisal, or a sponsor-created model.
The central underwriting question is not only whether the asset is attractive. It is whether the investor has a financeable right to cash flow or collateral, whether that right is enforceable, who controls the asset or proceeds, and what happens if the expected timing slips. A strong deal memo should explain the cash source, the control point, the downside remedy, and the valuation method in plain operational terms.
Example: a collectibles loan, litigation finance exposure, drug royalty interest, insurance sidecar, and LP secondary can all advertise asset-backed or contractual cash flow. The actual risk is different in each case: authenticity and custody for collectibles, merits and defendant collectability for litigation, patent and reimbursement risk for royalties, event severity and collateral release for insurance, and unfunded commitments plus stale NAV for secondaries.
Diligence questions
Legal right: identify exactly what is being purchased or financed. Is it a direct ownership interest, a note, a participation, a receivable, a royalty stream, an LP interest, a collateral assignment, a litigation proceeds interest, or a token representing an off-chain claim? Confirm whether the right is assignable, perfected, bankruptcy-remote, and senior or junior to other claims.
Control: determine who controls collections, custody, insurance, amendments, settlement decisions, sale timing, expense budgets, and reporting. A sponsor that controls both valuation and exit timing has more discretion than a structure with independent custody, third-party administration, investor consent rights, and hard distribution rules.
Valuation evidence: ask what supports the mark. Evidence can include closed transactions, administrator NAV, appraisals, auction comps, royalty statements, reserve reports, clinical sales data, legal damages analysis, insurance loss reports, or transfer-agent records. The weaker or older the evidence, the larger the valuation haircut investors should consider.
Downside path: map what happens if timing slips. If a lawsuit takes 5 years instead of 2, a drug royalty declines faster than forecast, a wine collection cannot be sold without a 25% discount, an insurance event traps collateral for multiple reporting periods, or an LP stake receives a capital call before an exit, the investor needs to know who funds the gap and whether distributions stop.
Structure and control points
Common structures include single-asset SPVs, series LLC interests, participation agreements, revenue-share contracts, collateralized loans, royalty purchases, continuation vehicles, fund secondary transfers, insurance-linked notes, custody-backed financings, and tokenized wrappers. The wrapper determines what investors actually own and which remedies they have if the asset underperforms.
Payment priority should be explicit. A basic waterfall may pay operating expenses first, then senior lender principal and interest, then reserves, then preferred return, then residual upside. Small changes in priority can move economics materially. Example: a 2% annual servicing fee paid before investors on a delayed 5-year exit can consume far more value than the same fee on a 12-month asset sale.
Control over cash and records is often the real protection. Bank accounts, lockboxes, custodians, transfer agents, administrators, collateral agents, trustees, claims counsel, operators, and servicers can matter as much as the named asset. Investors should know whether proceeds bypass the sponsor or land first in a sponsor-controlled account.
Conflict review is essential. Specialty-asset sponsors may originate, value, service, warehouse, sell, and manage the same asset. Related-party fees, affiliated buyers, internal marks, rollover options, or sponsor discretion around settlements and exits should be disclosed and tied to investor consent rights where possible.
Performance metrics
Useful metrics vary by asset class, but the reporting should connect contract value to realized cash. Litigation finance needs case status, budget burn, settlement posture, adverse-cost exposure, and defendant collectability. Collectibles need custody, insurance, condition, appraisal date, comparable sales, and liquidation channel. Royalties need gross receipts, deductions, payer statements, concentration, patent or contract duration, and audit rights. Secondaries need NAV date, discount, unfunded commitments, expected exits, and GP consent status.
Investors should compare base case, downside case, and delayed-exit case. Example: an asset underwritten to a 1.5x multiple over 3 years produces a different IRR if exit takes 5 years. A position marked at $1.0M with a target $1.5M sale may still be unattractive if custody, fees, taxes, appraisal slippage, and broker costs reduce net proceeds to $1.15M after a long hold.
Watch for stale valuations, missing counterparty data, unexplained markdown avoidance, related-party transactions, weak custody evidence, vague performance updates, repeated timeline extensions, or language that emphasizes activity instead of distributable cash. 'Progressing as expected' is not a substitute for proceeds, marks, reserves, and remaining risk.
Investor action: create a one-page bridge from legal right to cash. Start with the asset or contract, identify who owes money, identify who controls the payment channel, subtract senior claims and expenses, apply timing scenarios, then compare net proceeds with the investor's entry price. If that bridge cannot be built from available documents, the diligence file is incomplete.
