Private Equity Audit: Fund Requirements and Prep

Most private equity funds that have a registered investment adviser are required to undergo an annual private equity audit under the SEC’s custody rule. The audit must be performed by an independent public accountant registered with the Public Company Accounting Oversight Board (PCAOB), financial statements must be prepared under U.S. GAAP, and audited financials must be distributed to fund investors within 120 days of fiscal year-end (180 days for funds of funds). Even funds whose advisers are not SEC-registered often conduct voluntary audits to satisfy lender covenants and LP side-letter requirements.

Why Private Equity Funds Need Audits

The audit obligation for most private equity funds flows from SEC Rule 206(4)-2-2) under the Investment Advisers Act of 1940, commonly called the custody rule. When a registered investment adviser has custody of fund assets, which is nearly always the case because the general partner controls fund capital, the adviser must ensure the fund’s financial statements are audited annually and delivered to investors on time.

The SEC’s rationale is straightforward: PE funds hold illiquid, hard-to-value portfolio investments. An independent audit provides investors a check on management’s valuations and guards against misappropriation of assets. For LPs allocating capital to multiple funds, receiving audited financials is a baseline governance expectation.

Beyond the custody rule, fund agreements and LP side letters frequently contain independent audit requirements. Lenders to the fund or to portfolio companies often require audited fund-level statements before extending credit or approving distributions. When a PE fund sponsors an SBIC (Small Business Investment Company), the SBA has its own audit requirements on top of the SEC’s.

Who Is Covered

The audit requirement under Rule 206(4)-2 applies to investment advisers registered with the SEC. Advisers relying on the “exempt reporting adviser” exemption, such as smaller venture capital fund managers, face a lighter disclosure burden and are not subject to the full custody-rule audit pathway, though voluntary audits remain common in that segment too. When an adviser transitions from exempt to registered status (typically crossing the $150 million regulatory assets under management threshold), the annual fund audit becomes mandatory.

The Accounting Framework: ASC 946 and ASC 820

Investment Company Accounting Under ASC 946

Private equity funds that qualify as investment companies under U.S. GAAP apply FASB ASC Topic 946, which governs financial reporting for investment companies. ASC 946 requires that essentially all investments be measured at fair value, with changes in fair value flowing through the fund’s statement of operations. This is fundamentally different from the historical-cost model most operating companies use.

Under ASC 946, a PE fund’s core financial statements include:

• A statement of assets and liabilities (the fund’s balance sheet equivalent)
• A statement of operations showing realized and unrealized gains and losses
• A statement of changes in net assets
• A statement of cash flows
• A schedule of investments providing position-by-position detail

This specialized presentation gives LPs a clear picture of portfolio valuations and total return, without the consolidation of portfolio companies that would otherwise apply under standard U.S. GAAP.

Fair Value Measurement Under ASC 820

Because ASC 946 requires fair value measurement, the most consequential audit area in a PE fund is investment valuation. FASB ASC 820 establishes the framework for determining and disclosing fair value. Auditors test the fund’s valuations using three prescribed approaches: the market approach (comparable company multiples, recent transactions), the income approach (discounted cash flow), and the cost approach.

The fund must categorize each investment within the ASC 820 fair value hierarchy. Most PE portfolio company investments fall into Level 3, meaning they use significant unobservable inputs, because there is no active quoted market for private company equity. That Level 3 concentration is precisely why auditors dedicate substantial effort to evaluating management’s valuation models, key assumptions, and internal controls around the valuation process.

What a Private Equity Audit Covers

A private equity audit is not just a numerical review. Auditors examine multiple layers of the fund’s operations and financial reporting.

Fund-Level Financial Statements

The auditor tests whether the fund’s financial statements present fairly in all material respects in conformity with U.S. GAAP and ASC 946. This includes verifying capital account balances, tracing cash activity, confirming investment cost bases, and reviewing the allocation of income and losses among partners as specified in the limited partnership agreement.

Portfolio Investment Valuations

Valuation testing is the most time-intensive phase of a PE fund audit. The auditor reviews the GP’s quarterly valuation policies, tests the inputs and assumptions supporting each significant investment’s fair value, and may engage a third-party valuation specialist for complex positions. For each portfolio company, the auditor evaluates recent financial performance, recent transactions in the company’s securities, and comparable market data.

Management Fees and Carried Interest

Fund economics flow through the financial statements. Auditors verify that management fees were calculated correctly per the LPA, that any fee offsets or credits were applied properly, and that carried interest accruals are consistent with the fund’s distribution waterfall.

Related-Party Transactions and Co-Investments

PE funds frequently have co-invest vehicles, affiliated GP entities, and arrangements where portfolio companies pay monitoring fees to the GP. Auditors scrutinize these transactions to confirm appropriate disclosure and that terms are consistent with what was disclosed to LPs.

Carve-Out Financial Statements in PE Transactions

A concept closely related to fund audits is the carve-out financial statement, which PE deal teams encounter frequently on both the buy side and the sell side.

What Carve-Out Financials Are

When a PE buyer acquires a division or business unit from a larger corporation rather than a standalone company, historical GAAP financial statements for the carved-out business do not exist as a standalone entity. Carve-out financial statements are purpose-built to show the financial position and results of the target business as if it had operated independently, typically covering 2-3 years of history.

The principal challenge is allocating shared costs, such as corporate IT, human resources, treasury, legal, and facilities overhead, from the parent to the carved-out unit. These allocations must be reasonable, defensible, and disclosed in the notes. Costs that will not be incurred post-close are often presented as “as adjusted” rather than historical GAAP.

When They Are Required

Carve-out financial statements are required or expected in several PE contexts:

• A PE fund acquiring a division from a large public or private company
• A PE-backed company divesting a business unit to another buyer
• Add-on acquisitions where the target was an embedded business line without standalone financials
• Debt financing where lenders require audited historical results for the acquired entity

If the acquiring entity has SEC reporting obligations, Regulation S-X Rule 3-05 governs when separate audited financial statements of the acquired business are required, and the number of periods (one or two years) depends on significance measured under the tests in Rule 1-02(w). Related pro forma financial statements are governed by Article 11 of Regulation S-X. For purely private transactions, the scope is typically negotiated among buyer, seller, and lenders.

Audit Considerations for Carve-Outs

Auditing carve-out financial statements presents unique challenges. The auditor must gain comfort with cost allocation methodologies that may lack a direct cost-driver basis. They must also assess whether the statements reflect the economics the acquiring PE firm will actually inherit, or whether significant stranded costs will remain with the parent. PE deal teams should build carve-out audit timing into transaction schedules because the process routinely takes longer than a standard company audit and often runs on the critical path to close.

For fund audits that follow a PE acquisition involving carve-out financials, the opening balance sheet of the acquired entity as a fund investment feeds directly into the fund’s own investment valuation. Alignment between the carve-out audit and the fund audit firm is worth considering early.

Preparing for a Private Equity Fund Audit

The GP’s finance team drives audit readiness. Firms that treat the audit as an annual event requiring a data scramble tend to face long audit cycles and elevated fees. Firms that maintain audit-ready records throughout the year close materially faster.

Key Preparation Steps

Finalize the schedule of investments early. The schedule of investments, showing cost basis, fair value, and unrealized gain or loss for every portfolio position as of year-end, is the most scrutinized deliverable in the audit. Confirm cost basis records match the fund’s accounting system, and reconcile any difference between fund-level and portfolio company-level records before fieldwork begins.

Document the valuation process contemporaneously. GAAP requires valuation policies to be applied consistently. The GP should maintain written valuation memos for each significant portfolio company position, updated at each quarter-end, that lay out methodology, key assumptions, and supporting data. Auditors will ask for these memos; preparing them after year-end from memory is inefficient and increases audit risk.

Reconcile capital accounts. Each LP’s capital account balance drives distributions and carried interest calculations. Confirm that capital accounts tie to the fund’s general ledger and that all capital calls, distributions, and income allocations since inception net to the current balances.

Gather and organize support for management fees and expenses. Pull the management fee calculations for each quarter, confirm they match the LPA terms, and collect invoices or contract support for fund expenses charged to LPs. Fee transparency has been a recurring SEC examination focus.

Confirm auditor independence. Because the auditor must be PCAOB-registered and independent under Regulation S-X standards, the fund should verify that no portfolio company board seats, loans, or financial relationships compromise the auditor’s independence. PE funds with large portfolios sometimes discover independence issues late; a proactive independence assessment at the start of the engagement saves significant time.

Set realistic timeline expectations. Under the custody rule, audited financials must be distributed to LPs within 120 days of fiscal year-end, which for a December 31 year-end means April 30. Funds that begin preparing in January and provide complete support packages to auditors in early February typically hit this deadline with time to spare. Funds that begin in March routinely miss it.

The audit and assurance team at Modus works with PE fund clients to build structured audit-readiness programs that front-load documentation, reduce back-and-forth during fieldwork, and compress the overall timeline. AI-native audit processes mean workpapers are source-linked to underlying support, which accelerates the review cycle and reduces follow-up requests.

For PE deals that require carve-out financial statement work or quality-of-earnings analysis alongside the fund audit, Modus’s transaction advisory practice integrates both workstreams, reducing the coordination friction that slows deal timelines.

Frequently Asked Questions

Do all private equity funds need an annual audit?

Most PE funds managed by SEC-registered investment advisers are required to undergo an annual audit under the SEC’s custody rule (Rule 206(4)-2 under the Investment Advisers Act of 1940). Funds managed by exempt reporting advisers are not subject to the same mandate, but many conduct voluntary audits to satisfy LP expectations and lender requirements.

What auditing standards apply to private equity fund audits?

The auditor must be registered with and subject to inspection by the PCAOB. Audits are typically conducted under GAAS (Generally Accepted Auditing Standards) as issued by the AICPA, or under PCAOB auditing standards if the fund’s auditor is primarily a PCAOB-registered firm. Financial statements are prepared under U.S. GAAP, specifically ASC 946 for investment companies.

What is the deadline for distributing audited financials to LP investors?

Under the SEC custody rule, audited financial statements must be distributed to each investor within 120 days of the fund’s fiscal year-end. For funds of funds, SEC staff guidance extends the deadline to 180 days. Missing this deadline constitutes a custody rule violation and can draw SEC examination scrutiny.

What are carve-out financial statements and when does a PE fund need them?

Carve-out financial statements present a business unit or division as a standalone entity, typically for a transaction where the unit is being acquired separately from its parent. PE buyers frequently require carve-out financial statements, sometimes audited, when acquiring a division that did not maintain its own standalone GAAP books. The statements cover the allocation of shared costs and present a historical view of the business the acquirer will own.

How long does a private equity fund audit typically take?

Timing varies with fund complexity, portfolio size, and the GP’s level of preparation. A well-prepared mid-size fund with organized records, completed valuation memos, and reconciled capital accounts can complete the audit process in 8 to 12 weeks. Funds that begin the process late or provide incomplete documentation frequently extend to 16 weeks or longer, creating risk of missing the 120-day LP distribution deadline.

What is the primary focus area for auditors during a PE fund audit?

Investment valuation is typically the most significant audit area. Because PE portfolio investments are classified as Level 3 assets under ASC 820 (using significant unobservable inputs), auditors invest substantial time testing the fund’s valuation models, key assumptions such as EBITDA multiples and discount rates, and the GP’s internal controls around the valuation process. Capital account calculations and carried interest accruals are also closely examined.
