Life sciences accounting is dominated by estimates about science: how far along a trial is, whether a milestone is probable, what a pipeline asset is worth before approval. The cash burns years ahead of revenue, the deals are structured around contingencies, and the largest numbers on the income statement are accruals nobody invoiced yet.
We work across the sector’s range: pre-revenue companies entering the public markets, including through SPAC mergers, and US subsidiaries of global pharmaceutical groups reporting into foreign parents. The issues below are where the judgment concentrates, with the treatment for each.
Issue 01
R&D costs: expense now, capitalize almost neverASC 730
Development programs consume most of a clinical-stage company’s spend, and the instinct from other industries is to capitalize what builds future value. US GAAP mostly says no, and the exceptions are narrow enough that misreading them is a restatement pattern.
The treatmentResearch and development costs are expensed as incurred under ASC 730. Tangible assets with alternative future uses (lab equipment, facilities) are capitalized and depreciated, with the depreciation charged to R&D while used there. Nonrefundable advance payments for future R&D services are capitalized and expensed as the services are performed. Milestone payments to in-license pre-approval compounds are R&D expense when incurred in an asset acquisition context, because pre-approval IPR&D acquired outside a business combination with no alternative future use is expensed. Groups reporting into IFRS parents face a recurring difference: IAS 38 requires capitalizing development costs once its criteria are met, so the US GAAP books and the group package diverge by design, not error.
What we do: We set the R&D policy, and for groups reporting to IFRS parents we maintain the US GAAP books and a documented bridge to the group package.
From our engagements: For US subsidiaries of Japanese and Chinese pharmaceutical parents, we maintain exactly this dual view: US GAAP statutory books alongside group reporting packages, with a documented bridge for R&D and other recurring differences.

Clinical trial accruals: the estimate auditors test hardestEstimates
CROs and trial sites bill on their own schedules, often quarters behind the work. The company must accrue costs for patient visits, site activity, and pass-through expenses it has not been invoiced for, using enrollment data and contract budgets. This is routinely the highest-risk estimate in a clinical-stage audit.
The treatmentBuild the accrual bottom-up per study: contracted cost per patient and per site activity, multiplied by actual enrollment, screening, and visit data from the CRO and trial management systems, plus site activation and close-out fees as those events occur, reconciled against CRO budget reports and change orders. Percentage-of-effort on the total budget is a check, not the method. Reconcile invoices received to prior accruals every close and track the true-up rate; a persistent bias in one direction is the finding auditors write. Prepaid balances at CROs get the same treatment in reverse.
What we do: We build the bottom-up accrual methodology per study and the reconciliation your auditors test hardest, and run it every close.

License, milestone, and royalty revenueASC 606
Out-licensing deals stack an upfront payment, development and regulatory milestones, sales milestones, and royalties, often alongside R&D services and supply obligations. Each component recognizes differently, and bundling them wrong misstates several years at once.
The treatmentIdentify the performance obligations first: a license that is distinct from services is its own obligation. A license to functional IP (a compound the licensee can exploit as delivered) is recognized at a point in time when control transfers; symbolic IP is over time. Development and regulatory milestones are variable consideration, included only when it is probable a significant revenue reversal will not occur, which for approval-dependent milestones usually means waiting until the event is essentially assured. Sales-based milestones and royalties on licensed IP get the royalty exception: recognized as the underlying sales occur, never estimated in advance. Collaboration arrangements add an ASC 808 screen: units of account with a vendor-customer relationship run through ASC 606, and the rest present as collaboration revenue or contra-R&D with a disclosed policy.
What we do: We write the revenue memo that separates the license, milestone, and royalty components, so several years of revenue are not misstated at once.

Pipeline deals: asset acquisition or business combinationASC 805
Buying a compound, a platform, or a small biotech triggers the screen test, and the answer changes everything downstream: goodwill or none, IPR&D capitalized or expensed, contingent payments at fair value or recognized later.
The treatmentApply the screen: if substantially all the fair value is concentrated in a single identifiable asset or group of similar assets, typically one lead compound, the deal is an asset acquisition. Then: no goodwill, cost is allocated on relative fair value, acquired IPR&D with no alternative future use is expensed immediately, and contingent milestone payments are generally recognized when the contingency resolves (then as R&D expense pre-approval, or capitalized post-approval). If the deal fails the screen and includes an organized workforce plus substantive processes, it is a business combination: IPR&D is capitalized as an indefinite-lived intangible tested for impairment, contingent consideration sits at fair value with remeasurement through earnings, and goodwill absorbs the residual. Model both outcomes before signing, because the LOI structure often decides the screen.
What we do: We run the screen and write the memo at signing, modeling both outcomes, so the deal structure and the accounting are decided together.
From our engagements: We have run this analysis on both outcomes, including impairment cycles on capitalized IPR&D when programs stumbled. The screen memo written at signing is the cheapest document in the deal.

Pre-revenue companies entering the public marketsCapital Markets
Clinical-stage companies increasingly list through SPAC mergers paired with PIPE financings, selling a development plan and runway rather than revenue. The accounting workload lands in a compressed window: PCAOB audit uplift, reverse recapitalization mechanics, and public-company reporting with no revenue cycle to anchor it.
The treatmentThe target is usually the accounting acquirer, so the deal is a reverse recapitalization: the historical statements become the biotech’s, restated to PCAOB audit standard, with share counts recast by the exchange ratio. Pre-close instruments (SAFEs, convertible preferred, bridge notes) need classification memos before the auditors arrive, and PIPE warrants and earnouts run the ASC 815-40 analysis. Post-close, the reporting rhythm centers on burn: going-concern evaluation each period against the twelve-month window, clinical accruals as the dominant estimate, and stock compensation with 409A-supported valuations that the SEC examines against the deal price. Cash runway disclosure in MD&A must reconcile to the going-concern conclusion.
What we do: We handle the PCAOB audit uplift, the pre-close instrument memos, the reverse recapitalization, and the going-concern and runway disclosure through the listing.

Stock compensation with milestone and approval vestingASC 718
Life sciences awards vest on the events that matter: IND clearance, trial readouts, FDA approval, or an exit. Each vesting design has a different expense pattern, and pre-IPO grants draw cheap stock scrutiny in any registration.
The treatmentApproval and milestone triggers are performance conditions: measure grant-date fair value ignoring the condition, and recognize expense when vesting becomes probable, which for binary regulatory events often means a cliff of expense in the achievement period, with catch-up for prior service. Share-price triggers are market conditions: build them into grant-date fair value (Monte Carlo) and recognize over the derived service period regardless of outcome. IPO or change-of-control triggers are performance conditions generally not probable until the event occurs. For pre-IPO companies, keep contemporaneous 409A valuations and be ready to bridge grant-date values to the offering price, because the staff asks in nearly every life sciences registration.
What we do: We document the vesting analysis for each award and keep the 409A support and grant-to-offering bridge the SEC asks for in every life sciences registration.

US subsidiaries of global pharma groupsASC 740 / 850
A US operating subsidiary of a Japanese or Chinese parent lives in two reporting worlds: US GAAP for statutory and audit purposes, and the parent’s framework and calendar for consolidation. Intercompany arrangements dominate the balance sheet, and the tax provision carries transfer pricing exposure.
The treatmentRun US GAAP as the system of record and maintain a documented conversion bridge to the group framework: R&D capitalization, pension measurement, and lease differences recur every close. Intercompany license fees, cost-sharing, and distribution arrangements are related-party transactions with full ASC 850 disclosure, priced under a transfer pricing policy the tax provision must actually follow: ASC 740 here means uncertain tax position analysis on intercompany pricing, correct treatment of GILTI-adjacent flows from the US side, and return-to-provision discipline across two filing calendars. Build the group reporting package to the parent’s close timetable, usually days faster than a US-only close, and automate the recurring adjustments.
What we do: We run the US GAAP close, the group reporting package, and the audit coordination across both calendars, and automate the recurring adjustments.
From our engagements: This is standing work for us: US arms of Asia-headquartered pharmaceutical groups where we run the US GAAP close, the group package, and the audit alongside the parent's reporting calendar.
