M&A purchase accounting case study

M&A Purchase Accounting (ASC 805) Case Study

A $200M PE-backed holdco closed a $42M tuck-in acquisition and needed clean ASC 805 purchase accounting in 90 days — opening balance sheet, fair-value adjustments to identifiable intangibles, deferred-tax tracking, and goodwill recognition that survived the next external audit cycle without findings.

Client profile: Composite case study based on a $200M PE-backed acquirer purchasing a $42M revenue tuck-in target. NetSuite OneWorld (acquirer) consolidating in QBO target with planned migration. 90-day post-close ASC 805 timeline.

Company context

The client is a $200M PE-backed holdco completing the third tuck-in acquisition in its current platform thesis. The target is a $42M revenue specialty business — a complementary product line — being acquired for $42M cash plus $3M earnout contingent on year-1 revenue. The PE sponsor needed clean ASC 805 purchase accounting reflected in Q+1 reporting, including identifiable intangibles, deferred-tax positions, and goodwill recognition that wouldn't produce auditor findings.

ASC 805 (Business Combinations) is dense. The acquirer recognizes the assets acquired and liabilities assumed at fair value, identifies intangibles separately from goodwill (customer relationships, technology, trade names, non-compete), establishes deferred tax positions for book-tax differences, and recognizes goodwill as the residual. Common errors at close that surface in audit: under-allocation to identifiable intangibles, inconsistent valuation methodology, missed deferred tax, and incomplete bargain-purchase analysis.

  • Acquirer: $200M PE-backed holdco on NetSuite OneWorld
  • Target: $42M revenue specialty product line (asset deal structure)
  • Purchase price: $42M cash + $3M contingent earnout
  • Target stack pre-deal: QBO Advanced
  • Post-close: 90-day ASC 805 timeline + planned QBO → NetSuite migration in months 4–9
  • External audit cycle: December year-end (acquirer); audit fieldwork in February

Before — what was actually broken

Two acquisitions in the prior year had been booked with under-allocated intangibles — most of the purchase price went to goodwill, with token allocations to customer relationships and trade names. The auditor pushed back during fieldwork; the acquirer ended up restating intangibles and goodwill, recognizing additional amortization in current year, and producing a management-letter comment on M&A control design.

The CFO didn't want a third miss. We were brought in pre-close with a 90-day timeline to: identify and value intangibles per ASC 805, establish deferred-tax positions, complete the opening balance sheet, document methodology for the auditor walkthrough, and integrate the target's QBO actuals into NetSuite consolidation.

  • Two prior acquisitions resulted in audit pushback on intangibles allocation
  • Restatement and management-letter comment in prior year
  • No standard ASC 805 methodology in place
  • Target on QBO Advanced; acquirer on NetSuite OneWorld
  • Timeline pressure: Q+1 close 60 days post-deal-close

What Ledger Summit implemented

A six-track ASC 805 implementation: (1) pre-close due-diligence support to identify intangibles in advance; (2) third-party valuation of identifiable intangibles using income, market, and cost approaches; (3) opening balance sheet with fair-value adjustments; (4) deferred-tax establishment for each book-tax difference; (5) goodwill calculation as residual; (6) post-close integration into NetSuite with measurement period adjustments.

  • Pre-close diligence support: identifiable intangible inventory, customer-relationship modeling, technology assessment
  • Third-party valuation specialist engaged: customer relationships (Multi-Period Excess Earnings Method), developed technology (Relief from Royalty), trade names (Relief from Royalty), non-compete (With/Without Method)
  • Opening balance sheet: fair value of all identifiable assets and liabilities at close date
  • Deferred tax: established per book-tax difference (intangibles, fixed assets, deferred revenue, working-capital items)
  • Goodwill: residual of purchase price minus identifiable net assets fair value
  • Bargain-purchase analysis: ruled out (purchase price > identifiable net assets)
  • Contingent consideration (earnout): fair-valued at close; remeasured at each subsequent reporting date through P&L
  • Measurement-period adjustments: tracked for adjustments within 1 year of close
  • Working capital true-up: per purchase agreement, settled at day 60
  • Disclosure preparation: ASC 805 disclosures including pro forma revenue and earnings

ASC 805 mechanics — what the engine handles

Each step has documented methodology with reviewer sign-off and audit walkthrough memo.

TopicWhat it requires
Identify acquirerPer ASC 805-10-25; usually obvious from deal structure
Acquisition dateDate acquirer obtains control; not necessarily legal close date
Consideration transferredCash + assumed liabilities + contingent consideration at fair value + replacement awards (where applicable)
Identifiable intangibles — customer relationshipsMulti-Period Excess Earnings Method (MPEEM); typically the largest intangible
Identifiable intangibles — technologyRelief from Royalty Method; useful life based on technology obsolescence
Identifiable intangibles — trade nameRelief from Royalty; useful life often indefinite
Identifiable intangibles — non-competeWith/Without Method or Lost Profits; useful life = covenant period
Identifiable intangibles — backlogMPEEM or Lost Profits; useful life = backlog runoff period
Inventory step-upFair value at close; step-up flows to COGS as inventory sells
Fixed assetsFair value at close (replacement cost or market); useful life reset
Deferred revenueRe-measured to fair value (legal performance obligation only); may reduce vs. carrying
Deferred taxEstablished for book-tax differences; future reversal pattern impacts subsequent provision
GoodwillResidual; purchase price + NCI + step-up of prior interest − fair value of identifiable net assets
Bargain purchaseWhen fair value of identifiable net assets > purchase price; tested before recognizing goodwill
Contingent considerationFair value at close (probability-weighted); remeasured each period to fair value through P&L
Measurement periodUp to 1 year post-close to refine fair values; adjustments applied retrospectively
Bargain purchase gainRecognized in P&L immediately if material
DisclosurePro forma revenue and earnings; intangibles by type and useful life; goodwill changes

Implementation timeline

  • Weeks −4 to 0 (pre-close): Diligence support: identifiable intangibles inventoried; valuation methodology decided; deferred-tax positions modeled; valuation specialist engaged
  • Day 0 (close): Acquisition date established; control obtained; opening balance sheet captured at this date
  • Weeks 1–3: Third-party valuation of identifiable intangibles (customer relationships, technology, trade name, non-compete)
  • Weeks 4–6: Opening balance sheet finalization: fair value adjustments documented; deferred-tax positions established
  • Weeks 7–9: Goodwill calculation; bargain-purchase test; contingent consideration valuation
  • Weeks 10–11: NetSuite integration: target QBO mapped to NetSuite COA; opening balances loaded; consolidation logic tested
  • Week 12: First post-close consolidated close; ASC 805 disclosure drafted; auditor walkthrough memo prepared
  • Months 4–9 (post-close, ongoing): QBO → NetSuite migration of target as planned; measurement-period adjustments tracked; earnout fair value remeasured each quarter

When this approach fits

  • $10M–$200M acquisitions; tuck-in or platform-deal scale
  • PE-backed acquirer with quarterly portfolio reporting
  • Annual external audit cycle requiring clean ASC 805 within 6 months
  • NetSuite, Sage Intacct, or similar GL stack
  • Multi-acquisition platform thesis where standardization matters

Lessons learned and what we'd do differently

  • Engage in diligence, not after close. Identifying intangibles pre-close means valuation work starts immediately and methodology is decided before pressure.
  • Hire the valuation specialist. Auditors expect third-party valuation for material acquisitions; internal-only valuation is a finding waiting to happen.
  • Document deferred-tax thinking. Each book-tax difference at close becomes a future provision item; the rationale needs to be explicit.
  • Track measurement-period adjustments. Up to 1 year to refine fair values; document everything.
  • Earnout fair value matters quarterly. Remeasurement to fair value each period flows through P&L; assumptions need to be defensible.

Frequently asked questions

Why use a third-party valuation specialist?

Auditors expect independent valuation for material identifiable intangibles. Internal valuation is acceptable for small deals but produces audit pushback at this scale.

What's the difference between asset deal and stock deal for ASC 805?

Both are accounted for under ASC 805. Asset deals create a fresh tax basis = book basis (no deferred tax on intangibles); stock deals create permanent book-tax differences requiring deferred-tax tracking.

How do you handle contingent consideration (earnouts)?

Fair value at close (probability-weighted across outcomes); remeasure each subsequent period through P&L until settled. Disclosure of fair value methodology required.

What's the measurement period?

Up to 1 year post-close to refine fair value estimates as new information emerges. Adjustments are applied retrospectively (restate opening balance sheet); after 1 year, treat as current-period adjustment.

How does this work for stock acquisitions of public companies?

Same ASC 805 framework but with quoted-market-price for consideration. Step-up of any prior interest also requires fair-value remeasurement at close.

What about goodwill impairment testing?

Goodwill is tested annually for impairment per ASC 350. Triggering events between annual tests require interim testing. Step-zero qualitative test is the typical first step.

How do you handle in-process R&D (IPR&D)?

IPR&D capitalized at fair value at close; subsequently tested for impairment until completion or abandonment. Once complete, amortized over useful life.

What disclosures does ASC 805 require?

Pro forma revenue and earnings as if combined entities had operated together; intangibles by type and useful life; goodwill rollforward; contingent consideration; transaction costs.

Are transaction costs capitalized or expensed?

Expensed as incurred (legal, advisory, accounting). Different from prior GAAP where they were capitalized.

How does this support PE sponsor reporting?

Clean ASC 805 = clean Q+1 portfolio review. Sponsor diligence on the deal close already covered this; execution at close prevents downstream remediation.

Closing an acquisition? ASC 805 starts at diligence, not at audit.
