How to map shared-service separation dependencies for Corporate Carve-Out Transactions

Map shared-service separation dependencies by tracing each function the acquired business needs through the contracts, systems, people, data, and facilities that enable it. Identify what transfers, what remains with the seller, what requires third-party agreement, and what the buyer must replace. The deliverable is an evidence-linked separation dependencies matrix showing continuity risks, contractual coverage, timing conflicts, and accountable owners. Use it to test whether the proposed transition services agreement supports operations through migration—not merely whether it lists familiar service names.

When to use this workflow

Use this workflow when diligence shows that the acquired business relies on a parent or retained affiliate for payroll, procurement, treasury, software, logistics, premises, or other operating support. Buyer’s counsel should coordinate with integration, IT, finance, HR, and business leads before transition services agreement (TSA) scope and purchase-agreement risk allocation become settled.

The scope is separation readiness: identifying dependencies and securing a supported route from seller-provided service to buyer-controlled operation. It is not a complete integration plan.

This is a US-oriented professional workflow guide. Transfer rights and continuity obligations require review of the operative documents, governing law, transaction structure, third-party rights, and local requirements. The filed agreements cited below illustrate negotiated provisions, not generally applicable law or market standards.

What you need

Request documents for the business perimeter and its supporting infrastructure, not just contracts held by target entities:

• The entity, asset, employee, IP, data, permit, and premises perimeter, including retained items used by the business.
• Shared and parent-level contracts, amendments, order forms, intercompany arrangements, licenses, guarantees, and relevant vendor correspondence.
• The purchase agreement, disclosure schedules, TSA and service schedules, and proposed supply, IP, lease, and employee arrangements.
• Service inventories, application diagrams, data flows, staffing allocations, migration proposals, and proposed shutdown dates.
• Business-owner explanations of volumes, locations, peak periods, manual alternatives, and replacement readiness.

Assign stable document IDs and preserve version and execution status. Distinguish missing documents, redacted provisions, and unverified operational statements. Treat a service owner’s assurance as a diligence lead, not proof of the buyer’s contractual access rights.

Use the template

Use the Corporate Carve-Out Transactions — Separation dependencies matrix below. Copy this table into your working document or spreadsheet. Create one row per material service-to-dependency relationship; link rows when several services depend on the same upstream resource.

Use stable row IDs so payroll can point to an identity-access row without duplicating its analysis. Provider / recipient identifies the legal entities supplying and receiving the service; record a different asset owner in the dependency analysis. In Evidence / status, identify the document ID, version, clause or page, and whether the proposition is verified, reported, or unresolved. Distinguish legal interpretation from source text.

Separation route should state transfer, standalone replacement, TSA coverage, delayed transfer, or unresolved—not simply “in progress.” Timing / conflict records the trigger and mismatch between availability and replacement readiness. Owner / acceptance names the accountable buyer lead and evidence needed to close the issue. Put reconciliation dates and next decision dates in the relevant cells or linked issue record.

Step by step

1. Define the operating perimeter and necessary services

Start with the acquired business’s activities: employing staff, accepting orders, shipping products, paying suppliers, and maintaining records. Ask each functional lead what the business cannot do independently on the proposed closing date and which parent support is expected to stop then.

For every service, identify the provider’s legal entity, receiving entity, locations, and business coverage. Separate ownership from use: a target employee may administer an application licensed to a retained parent.

Record the service and provider/recipient in the matrix. Where the perimeter is disputed, identify the unresolved asset, population, or location. Do not map an assumed future perimeter as though it were agreed.

2. Trace upstream dependencies beyond the service name

Ask what must remain available for each service to work. Payroll may require employee data, identity access, a payroll application, a bank interface, and seller personnel. Logistics may require warehouse access, inventory systems, vendor contracts, and customer data.

An actual TSA schedule illustrates this approach: the Seres–Nestlé schedule identifies IT.03 as a dependency for HR administration and vendor-contract conveyance and supporting services for logistics. This is a mapping example, not a required format. See the Seres–Nestlé TSA, Schedule of Services.

Create linked rows for material upstream services. Record who confirmed each relationship and what verification remains outstanding. Continue tracing until the dependency reaches a buyer-controlled resource or supported external arrangement. Flag circular dependencies rather than assuming either service can migrate first.

3. Verify the legal route for continued use

Review the underlying contract, not merely its title or disclosure-schedule listing. Check the contracting entity, covered users, permitted affiliates, assignment and change-of-control provisions, partial-transfer restrictions, third-party service rights, and termination provisions. Identify any intercompany termination provision that could remove existing support at closing.

Test the proposed route: contract transfer, separate vendor arrangement, or seller-provided TSA service. If the seller proposes continued use of a vendor platform, identify the contractual basis and required approvals.

Matthews–Duravant Section 5.5(b) illustrates why elections matter: it ties reasonable-best-efforts obligations for standalone shared-contract arrangements to a written buyer election within specified 30-day periods, excluding specified shared-location leases and TSA-supported contracts. The efforts obligation does not guarantee agreement. See Section 5.5(b).

Record the route, clause, outstanding consent or election, and negotiator. Apply the actual agreement’s trigger, not the example’s period.

4. Compare TSA coverage with the dependency chain

Match each needed service to a TSA schedule entry. Compare its description with required users, locations, volumes, systems, personnel, and data access. Review exclusions, standards, capacity, change control, fees, pass-through approvals, continuity arrangements, liability limits, and exit assistance.

Do not treat “HR support” as sufficient without checking whether identity access and payroll processing are included. Likewise, confirm that a listed application comes with the personnel and data needed to operate it. For data dependencies, assign counsel to verify the proposed access and migration permissions and restrictions.

Record uncovered components as explicit gaps. Link drafting corrections to affected rows and distinguish requested language from agreed coverage. Ask the business owner to confirm that the contractual description matches the operating requirement.

5. Test timing and distinguish operational risk from closing rights

Compare upstream end dates with downstream service terms, replacement lead times, testing periods, and migration dates. Work backward from demonstrated readiness, not just TSA expiry. Preserve whether each date is fixed, event-triggered, extendable, or a planning assumption. Identify extension notice requirements and who must act.

Do not assume an operationally critical consent gives the buyer a right not to close. Matthews–Duravant Section 5.5(e) excludes specified failures to obtain consents or effect transfers or arrangements from closing-condition assessment, except to the extent of a breach of Section 3.4 or 5.5. Read those provisions with Article VIII. See Section 5.5(e).

Record the timing conflict and contractual treatment separately. Escalate continuity risks even where they are not express conditions; label proposed protections as negotiation requests.

6. Assign mitigation and buyer acceptance evidence

Choose a specific response for each gap: obtain consent, negotiate standalone access, extend an upstream service, narrow an exclusion, procure a replacement, or establish a tested interim process. Identify cost responsibility and seller or vendor dependencies without assuming those parties have accepted them.

Name one accountable buyer owner and identify contributors. Define acceptance evidence: an executed vendor arrangement, verified user access, reconciled data migration, or successful business-owner test. A project status marked “complete” is not sufficient.

Record mitigation, the decision owner, evidence requirement, and next decision date. Keep proposed solutions open until contractual and operational elements are verified, or record an authorized buyer decision accepting a defined residual risk.

7. Reconcile the matrix against the current deal documents

Before using the matrix for a buyer decision, reconcile it against the latest purchase agreement, TSA, ancillary agreements, and vendor arrangements. Check entity names, service identifiers, definitions, durations, and cost allocations. Preserve superseded versions while identifying the current working version and whether it is executed.

Review changes with business owners. A shortened IT term may affect several downstream rows even if their schedules remain unchanged. Check that replacement readiness includes needed exit assistance and continued access to records.

Record the reconciliation date and reviewer, update linked dependencies, and produce a focused open-issues list. Each unresolved row should state the decision needed, decision-maker, and proposed diligence, drafting, or operational action.

Worked example

Fictional scenario: Alderbridge Components LLC proposes to acquire the pump business of Bracken Industrial Holdings. Payroll and order fulfillment depend on Bracken’s retained systems. The draft TSA provides six months of payroll support, two months of identity access, and three months of logistics support, each beginning at closing. Buyer migration leads estimate four months for independent payroll, but have not validated that estimate.

Diligence includes a draft TSA, parent software agreement, and operations memorandum. The warehouse vendor order form and amendments are missing. Bracken currently provides all three services to its pump division; the TSA would provide them to Alderbridge after closing. All parties, documents, clauses, and timings below are fictional.

The mapping changes the buyer’s decision. Six months of payroll support initially appears sufficient, but two-month identity access undermines that conclusion. The buyer needs a supported access route and aligned duration—not simply a longer payroll term. Even a four-month extension may be insufficient without validated migration and testing time.

For logistics, the evidence supports investigation, not a conclusion that assignment is prohibited or consent required. The buyer assigns the missing-document request and withholds a readiness recommendation pending supported access and implementation timing. None of these findings establishes a closing-condition failure without reviewing the purchase agreement.

Common mistakes

• Listing departments instead of dependencies. Replace “finance” with specific services and their systems, personnel, banking arrangements, and data.
• Treating TSA inclusion as vendor authorization. Check third-party rights and record approvals separately from seller promises.
• Using one end date for a service chain. Record each upstream term, extension mechanism, and downstream effect.
• Equating criticality with a closing condition. Cite the operative condition and qualifications; escalate operational exposure separately.
• Closing rows on assurances alone. Require acceptance evidence or document authorized acceptance of a defined residual risk.

Final quality check

• Every material service identifies its provider, recipient, and business coverage.
• Upstream dependencies have stable IDs and traceable downstream links.
• Contract conclusions cite verified source versions and exact clauses or schedules.
• Missing, redacted, reported, and draft evidence remain distinguishable from established rights.
• TSA coverage and underlying vendor rights are both addressed.
• Timing conflicts reflect triggers, extension requirements, and migration assumptions.
• Closing-condition analysis is separate from operational readiness.
• Open issues have accountable owners and decision paths; closed issues retain acceptance evidence or documented risk decisions.

Frequently asked questions

Should every shared service become a TSA service?

No. Some may transfer, be replaced before closing, or become unnecessary. Record the supported route and dependencies first. Avoid selecting a transition service that leaves the underlying access problem unresolved.

How granular should the matrix be?

Split rows when dependencies have different owners, legal rights, end dates, or acceptance evidence. Keep immaterial technical detail in linked operational records. Counsel should be able to identify which failure changes the buyer’s decision.

Can management confirmation close a dependency issue?

Use it for operational facts within the speaker’s knowledge, identifying the source and scope. Do not substitute it for contractual permission. Obtain the document or acceptance evidence needed for the specific conclusion.

When can the buyer recommend terminating a TSA service?

After reviewing termination mechanics and verifying buyer-owned replacement readiness. Check downstream dependencies, migration evidence, business-owner acceptance, and remaining seller support before recommending termination. Assign responsibility for required notices rather than treating a migration milestone as notice.
