Excluded assets in an asset purchase: the records left behind in the seller entity

Why the seller entity can still hold valuable data after closing

In an asset purchase, the buyer takes the assets listed in the agreement and the seller keeps everything else as excluded assets. Historical email, archived file shares, closed customer files and old system exports often end up on the excluded side, or as copies kept by both parties. If the seller entity still holds those records, owns the rights and has someone who can sign, they may be licensable to AI labs and data buyers through SourceX after closing.

Purchase agreements vary, but a few patterns recur. Many define purchased assets to include books and records relating to the business, while the seller keeps its corporate, tax and excluded-liability records, or keeps originals and gives the buyer copies. Others transfer everything and leave the seller only a right of access. Which pattern applies decides whether anything is left to license.

Copyright law adds a wrinkle: ownership of a copyright can be transferred in whole or in part, and any of the exclusive rights can be transferred and owned separately (17 U.S.C. 201). A purchase agreement can therefore leave the seller holding some rights in its historical material while the buyer holds others, so read the actual language rather than assuming.

The deal flow makes this worth a standing check. McKinsey estimates that by 2035 about six million US small and medium-size businesses will face ownership transitions as baby boomers retire, with more than one million viable candidates for sale (McKinsey, The great ownership transfer). Every asset sale among them leaves a seller entity with decisions to make about its records.

The APA clauses that decide what stayed behind

Timeline: when to raise records in the deal

Dissolution and winding-up rules are set by state law, so the seller's counsel should confirm who can act for the entity at each stage. Export formats and storage choices are covered in how to preserve company records before shutting down systems.

Who signs for the seller after closing

The seller's authorized sponsor is whoever can still bind the entity: the owner, a remaining director or officer, or a wind-down officer appointed for the purpose. Two complications come up often:

• The owner joined the buyer. An employment agreement or the APA's restrictive covenants may limit what the owner can do for the seller entity. Clear it with counsel first.
• The seller entered an ABC or bankruptcy. An assignee or trustee now controls the assets and must be involved; the ABC assignee day-one records checklist shows what they look at first.

How an M&A advisor makes the introduction

1. Confirm with the former owner that the excluded records still exist and that the seller entity has not been dissolved.
2. Run the company fit checker against the baseline on who qualifies: 50+ full-time employees at peak (contractors excluded), several years of documented operations, rights and a signer. A seller that no longer operates can still qualify, as long as the data exists.
3. Register as a partner, then either share your personal referral link with the former owner so the seller can apply at sourcex.si/apply under your code, or enter the seller yourself on the referral form.
4. SourceX qualifies the seller and reviews rights, including what the APA transferred and what copies the buyer holds.
5. The seller completes a data inventory of retained systems and archives; you never handle or describe the records.
6. Price and terms are agreed, and nothing binds the seller until it signs. Buyers review, the license is executed, data is delivered under agreed redaction rules, and the seller is paid.

What to say to a former client after closing

The M&A advisors hub has more ways to raise licensing with clients before and after a sale.

Check your own rules before accepting a reward

Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company, and the reward becomes payable only after the buyer pays and SourceX receives its fee. It is not deducted from the seller's proceeds, and no reward is guaranteed.

Two rules come up for M&A advisors. The Exchange Act's M&A broker exemption in 15 U.S.C. 78o(b)(13) concerns brokers effecting securities transactions in connection with the transfer of ownership of an eligible privately held company; it is not a general finder exemption and does not address data-licensing introductions. And if you are a registered representative, FINRA reported that the SEC approved new Rule 3290 on outside activities on September 15, 2026, replacing Rules 3270 and 3280, with the effective date to be announced and the existing rules applying until then (FINRA weekly update). Tell your firm's compliance team before you register.

This is general information, not legal, tax or financial advice. Confirm with your own counsel, tax adviser or professional body before acting.

Red flags in a seller-entity referral

• The APA transferred all books and records, or the seller's confidentiality covenant covers the material.
• The only copy of the archive sits in the buyer's systems.
• The records are mainly customer personal data; business records vs personal data in a bankruptcy sale explains why that distinction matters.
• The entity has been dissolved and nobody has authority to act for it.
• The former owner rules out granting exclusive AI-training rights for a set period.

Next step

Pull the excluded assets schedule and records clause from your recent asset sales and check what each seller kept. Where an archive survives, register as a partner and introduce the seller before the entity winds down.
