Carry every asset at the value it actually has.

Section 01

Why the register is harder than it looks.

A fixed-asset register looks like a list, and buyers treat it like one at their cost. Each line carries cost, accumulated depreciation, net book value, useful life, depreciation method, in service date, and often a separate tax basis and tax depreciation history. Migrating the register is not copying a spreadsheet. It is reconstructing the depreciation engine for every asset so that the new system continues the accounting exactly where the old one stopped, with no step change in the balance sheet or the depreciation charge.

The register also feeds tax, insurance, and the impairment review, so an error propagates well beyond the balance sheet. Overstated asset values inflate depreciation and distort tax. Understated values mean assets the business depends on are invisible to the controls that should protect them. The register is small in line count and large in consequence, which is exactly the kind of work that gets under resourced in a carve-out and then causes problems for years.

Because the register is a sub ledger feeding the general ledger, its migration must be sequenced and reconciled before the ledger cutover relies on it. The asset control account in the new ledger has to equal the sum of the migrated register, to the dollar. That reconciliation is the gate, and it is covered alongside the wider move in the TSA general ledger cutover.

Section 02

Deciding which assets transfer.

The first task is to identify which assets belong to the carved-out business. The deal documents define the perimeter, but the register often does not map cleanly to it. Assets may be shared across the retained and divested businesses, located at sites that are themselves split, or recorded against a legal entity that does not match the new ownership. The buyer works from the purchase agreement schedules and reconciles them to the physical reality, resolving every asset that is ambiguous rather than guessing.

Shared assets are the hard case. A piece of equipment used by both businesses, or a leasehold improvement at a shared site, needs a clear answer on who owns it, who uses it, and how cost is allocated if use continues during the TSA. The buyer should not accept a register that quietly assigns shared assets to Newco without a basis, because it inherits both the value and the obligation to maintain and eventually replace them.

Capital work in progress deserves separate attention. Projects under construction at the cutover carry accumulated cost but no depreciation yet, and the buyer needs to know which projects transfer, their committed spend, and when they will be capitalized. A construction project that lands on Newco's books without a clear completion and funding plan is a surprise the buyer can avoid by mapping work in progress before the migration, not after.

Section 03

Carrying depreciation and the tax basis.

Each asset must carry forward at its existing net book value, with accumulated depreciation and remaining useful life intact. Resetting depreciation at the cutover would overstate asset values and inflate future depreciation, producing a step change in the financial statements that no auditor will accept and no buyer should want. The migration preserves the depreciation history so the new system continues charging depreciation on the same basis the old one used, asset by asset.

The tax basis is the trap. For many assets the tax basis differs from the book value, because tax depreciation uses different methods, conventions, and lives than book depreciation, and prior tax elections may have accelerated or deferred relief. The buyer must capture the tax basis and the tax depreciation history separately, not assume they equal the book figures. Getting this wrong misstates future tax depreciation and the deferred tax balances, and the error can persist for the full life of the assets.

Leases add another layer. Right of use assets and the corresponding lease liabilities must move with their amortization schedules and remaining terms intact, and any lease that does not transfer with the asset needs a plan. The buyer maps book depreciation, tax depreciation, and lease accounting together, because they all sit in the register and all feed the close described in the TSA month end close coordination.

Section 04

Verifying the assets actually exist.

Carve-out registers are rarely as accurate as they appear. Over years of operation they accumulate ghost assets, items that were disposed of, scrapped, or sold but never written off the register, and they miss assets that exist on the floor but were never properly recorded. Migrating a register without testing it means carrying value that is not there and missing value that is, both of which distort the balance sheet and the insurance position.

Where practical, the buyer runs a targeted physical verification before migration, focused on material assets rather than every low value item. The verification confirms existence, condition, and location, and gives the buyer a basis to write off ghost assets and capitalize anything found unrecorded. This is also the moment to update asset tagging so the new business can track its assets after exit, rather than inheriting an untagged population it cannot easily verify again.

The verification feeds the impairment and useful life review. An asset that exists but is obsolete or idle may need its life shortened or its value impaired, and the cutover is the natural point to make that judgment with fresh eyes. The buyer that verifies and reviews at migration starts Newco with a register it trusts. The buyer that migrates on faith starts with a register the first audit will pick apart.

Section 05

Reconciling and exiting.

The migration is complete when the register reconciles to the general ledger control account and both parties sign off the closing position. The sum of cost, the sum of accumulated depreciation, and the resulting net book value in the new register must equal the control account in the new ledger, to the dollar. Any difference is investigated and cleared before the asset service is switched off. This reconciliation is the proof, and it should be documented as a control artifact the first audit can test.

The buyer should also run one depreciation cycle in the new system before exit, confirming the depreciation charge matches what the old system would have produced for the same period. A mismatch reveals an error in lives, methods, or conventions that is far cheaper to fix before exit than after. Running the cycle in parallel while the seller's system is still available gives the buyer a clean comparison and a fallback if something does not tie out.

Fixed-asset migration is a contained workstream that rewards precision, and accelerating it cleanly removes a dependency that often lingers longer than it should. The buyer that maps the perimeter, carries the two bases correctly, verifies the population, and reconciles to the ledger exits with a register it can defend. Sequencing that work against the rest of the financial exit is part of the TSA Exit Acceleration service.

FAQ

Asset migration questions buyers ask.

What moves in a fixed-asset register migration?

The carved-out assets, each with its cost, accumulated depreciation, net book value, useful life, depreciation method, and in service date. The buyer also needs the tax basis where it differs from the book value, any capital work in progress, and the lease detail. The migration must reconcile to the asset control account in the general ledger.

Why carry accumulated depreciation rather than reset it?

Because resetting depreciation overstates asset values and future depreciation, distorting both the balance sheet and the tax position. The buyer carries each asset at its existing net book value with its accumulated depreciation and remaining life intact, so the financial statements continue without a step change at the cutover.

Does the asset register need a physical verification?

Where practical, yes. Carve-out registers often contain ghost assets that were disposed of but never written off, and missing assets that exist but are not recorded. A targeted physical verification of material assets before migration prevents the buyer from carrying value that is not there or missing value that is.

How does fixed-asset migration affect tax?

Significantly. The tax basis of an asset often differs from its book value, and the tax depreciation method and conventions differ by jurisdiction. The buyer must capture the tax basis separately, not assume it equals net book value, or it will misstate future tax depreciation and the deferred tax position.
