How to Record a Fair Value Mark-to-Market Unrealized Gain on a Portfolio Investment
Recording the quarterly or annual fair value adjustment on a private equity portfolio company investment under ASC 820, resulting in an unrealized gain flowing through the fund's income statement.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Investments at Fair Value - Portfolio Company B | Asset (+) | 1,200,000.00 | - |
| Net Change in Unrealized Appreciation - Investments | Income (+) | - | 1,200,000.00 |
💡 Accountant's Note
Under ASC 946 (Investment Companies) and ASC 820, private equity funds carry portfolio investments at fair value with all unrealized gains and losses flowing through the income statement each period. Fair value is typically determined using a combination of market multiples (EV/EBITDA), recent transaction comparables, discounted cash flow (DCF), or the price of a recent round of financing.
Practitioner & Systems Framework
💻 ERP Architecture
The fair value adjustment is recorded as a mark in the portfolio accounting system. The cost basis does not change — only the fair value layer is updated. NAV per unit/share calculations must reflect the updated fair value for LP reporting.
⚠️ Audit Flags
Fair value estimates for illiquid private investments are one of the highest-risk audit areas. Auditors (often using a valuation specialist) will independently validate the valuation methodology, comparable company multiples, financial projections, and DLOM (Discount for Lack of Marketability) applied. Expect significant back-and-forth on Level 3 inputs.
📄 Required Documentation
Valuation committee memo and sign-off, Board-approved valuation policy, comparable company analysis, portfolio company financial statements (trailing LTM), DCF model, third-party valuation report (if obtained).
