Venture Fund NAV and Valuation: How private investments are marked

Net Asset Value (NAV) is the value of a fund's assets less its liabilities at a particular reporting date. Venture funds often hold private-company securities that trade infrequently. A manager therefore needs an evidence-based process to estimate what those positions are worth at that date.

NAV is a current reported measurement rather than a prediction of the cash an LP will receive. The number can change when portfolio companies raise capital, operating expectations move or new information affects the estimated value of a security.

How is NAV calculated?

NAV = Fair value of investments + Cash + Other assets − Liabilities

Suppose a fund has investments marked at $25 million, $2 million in cash and $500,000 of receivables. It also has accrued liabilities of $800,000.

NAV = $25.0M + $2.0M + $0.5M − $0.8M = $26.7M

The fund-level figure is an accounting total. Allocating that value among LPs and the GP may require additional fund-specific calculations, particularly where carry and partner-account provisions apply.

How a venture position gets its mark

A valuation process starts with the security owned, its contractual rights and evidence available as of the measurement date. Recent financing terms, company operating results, relevant comparable securities and expected exit scenarios may all contribute to the assessment.

A recent financing can be persuasive evidence when its transaction terms are relevant. Its headline post-money valuation may imply different values for preferred shares, common shares or convertibles because the instruments have different protections and cash-flow rights.

The International Private Equity and Venture Capital Valuation (IPEV) Guidelines provide a recognized approach to fair-value judgments in private capital. Funds should apply their own documented valuation policy consistently with applicable accounting standards.

Illustrative share-class example: a new round values the company at $100 million post-money, but investors in that round receive a liquidation preference while the fund holds an older class. The headline valuation alone cannot establish the fair value of the fund's particular security. A valuation process must examine rights, liquidity assumptions and the allocation of exit proceeds across the actual cap table.

Write-ups, write-downs and write-offs

A write-up increases the reported fair value of a position. A write-down reduces it, while a write-off generally recognizes a position with no remaining value under the adopted policy. Each change should be supported by the new evidence and the reasons the prior estimate changed.

For example, a fund that invested $1 million in a company may mark its position at $1.8 million after reviewing a new priced financing and the rights of its own shares. A later operating deterioration could justify reducing that mark. Historical cost remains $1 million through those valuation changes.

How NAV changes return metrics

The unrealized part of portfolio value feeds RVPI and TVPI, while value already distributed contributes to DPI. Investment cost and current position value determine MOIC at the investment level.

Unrealized marks also influence reported IRR at interim dates. That is one reason investors examine how much of performance has been realized before treating a headline return as durable.

What makes a useful valuation process?

Set a clear valuation date, document methodology, preserve security-level records and identify the evidence supporting material changes. A reviewer should be able to reconstruct why a position moved from its prior mark.

An investment team may own the company narrative, while a valuation committee, finance team or external provider challenges the assumptions. The administrator posts approved values into the official fund books.

The IPEV Valuation Guidelines (December 2025 edition) provide a current framework for private-capital fair-value analysis. Apply the edition and measurement policy adopted by the fund and confirm its consistency with relevant accounting standards.

Common valuation errors

Applying a headline company valuation to every share class

Liquidation preferences, conversion mechanics and other rights matter. The value of the company and the value of the fund's exact security can differ.

Confusing a new investment with a valuation gain

A follow-on increases invested cost and ownership. A mark should represent current fair value of the resulting position, with those movements recorded separately.

Reusing a stale mark without new analysis

An unchanged valuation may be appropriate, but it needs an assessment against current facts and the valuation policy. Simply carrying the previous figure forward can hide deterioration.

Keeping valuation history usable

Treto can help preserve company reporting, financing events, source documents and prior investment conclusions around each position. This reduces the effort of gathering evidence for a valuation review. The approved mark and NAV calculation remain governed by the fund's formal accounting and valuation process.
