Portfolio Monitoring

What is portfolio monitoring?

Portfolio monitoring is the recurring practice of collecting, validating and analyzing company-level information across every position a fund holds: financial results, operating metrics, cash and runway, ownership and the current carrying value. Its output feeds three decisions, namely how to mark the book, where to put reserves, and what to tell investors.

What is portfolio monitoring in private equity?

Same practice, different instrument panel, and the standard-setting work is further along here than in venture. ILPA has published a Portfolio Company Template since 2019, when it released the Portfolio Company Metrics Template, describing it as answering the need for a more efficient and comprehensive method of reporting portfolio company metrics for buyout and growth equity funds and as offering a format for reporting details about the individual companies held by a limited partner's fund investments. ILPA noted the problem the template was built to solve: limited partners had historically requested that information from their general partners in bespoke formats, so standardizing the request lets limited partners receive more timely and consistent data while general partners report once instead of completing multiple customized forms. The 2019 template was developed by roughly 30 limited partners, general partners, advisers and data service providers.

That template is now being replaced. ILPA describes the current Portfolio Company Template as offering comprehensive reporting about the individual companies held by a fund, and says the refreshed version is designed to give limited partners a more detailed look into the investment positions held by the fund, offering streamlined but detailed deal-level exposure data, company-specific key performance indicators and investment transaction details. The public comment period on the draft closes October 2, 2026 and ILPA intends to release the final version in January 2027.

What do LPs expect to receive?

Read the standard-setter's sequencing and the answer is clear. Fund-level fee, expense, carried interest and performance standardization arrived in 2025 with the updated ILPA Reporting Template and the new ILPA Performance Template. Company-level standardization arrives in January 2027 with the refreshed Portfolio Company Template. Until then, what a limited partner receives at the company level is whatever the limited partnership agreement requires, which is why ILPA frames its templates as supplementing the quarterly reporting a general partner provides as part of its standard package, including audited and unaudited financial statements prepared under U.S. generally accepted accounting principles, international financial reporting standards or another comprehensive basis, as mandated by the fund's limited partnership agreement and other governing documents.

Three expectations hold regardless of template adoption: that a position's cost and its fair value both appear, that the metrics reported this quarter are defined the same way they were last quarter, and that the manager can explain how the fair value estimate was reached.

The monitoring cadence

• Monthly, for companies where it is warranted: cash balance, net burn, and months of runway. Runway is the metric that forces a decision, so a monthly cadence for it is worth the friction even when everything else is quarterly.
• Quarterly, for everything: revenue and the revenue build, gross margin, headcount, the two or three operating metrics specific to the company's model, the cap table as it stands after any new round, and the carrying value with its basis.
• At every financing event: new price per share, new preference stack, the fund's post-round ownership on a fully diluted basis, and whether the pro rata right was exercised.
• Annually: the audit's valuation testing, and a reserve review across the whole portfolio rather than company by company.

What gets collected, and by whom

The collection problem is that the data does not belong to the fund. It belongs to companies that have their own closing calendars and their own tolerance for reporting requests, and the information rights in the financing documents set the floor for what can be demanded.

The valuation side of monitoring also has a disclosure consequence a manager should understand. Form ADV Part 1A, Schedule D, Section 7.B.(1), question 27 asks what percentage of a private fund's assets by value was valued during the last fiscal year by a person, such as an administrator, that is not a related person of the adviser, counting only assets where that person carried out the valuation procedure and where the resulting valuation was used for subscriptions, redemptions or distributions and for fee calculations. For most venture funds the honest answer is a low number, which is a public statement that monitoring and marking are the manager's own work.

Dedicated portfolio monitoring platforms exist and most managers past a first fund use one, but the collection cadence, the metric definitions and the reserve decision are the manager's job regardless of the tool.

A worked example

Figures are hypothetical. A fund holds 22 active positions with a total cost basis of 96,000,000 dollars and a reported fair value of 180,000,000 dollars, a gross multiple of 180,000,000 divided by 96,000,000, or 1.88 times.

Concentration first. The three largest positions are carried at 46,000,000, 31,000,000 and 22,000,000 dollars, which sum to 99,000,000 dollars, or 99,000,000 divided by 180,000,000, exactly 55 percent of fair value. Those three cost 21,000,000 dollars in total, so their multiple is 99,000,000 divided by 21,000,000, or 4.71 times. The other 19 positions cost 96,000,000 minus 21,000,000, or 75,000,000 dollars, and are carried at 180,000,000 minus 99,000,000, or 81,000,000 dollars, a multiple of 81,000,000 divided by 75,000,000, or 1.08 times. The fund's headline 1.88 times is three companies; the rest of the book is at cost plus a rounding error.

Collection quality next. Of the 22 companies, 19 returned their quarterly metrics by the deadline, so collection was 19 divided by 22, or 86 percent. The three that did not are, by construction, the three about which the manager knows least.

Then the decision the monitoring exists to force. One company reports a cash balance of 2,400,000 dollars and net monthly burn of 400,000 dollars, which is 2,400,000 divided by 400,000, or 6 months of runway. Six months triggers a reserve question now, not at the next annual review: either the fund commits a follow-on, or it plans for the company to raise from someone else at a price it does not control, or it prepares to write the position down. That is the entire purpose of the cadence.

Common mistakes

• Changing a metric definition mid-life. If net revenue retention is computed one way in 2025 and another in 2026, the trend is an artifact and every conclusion drawn from it is wrong.
• Monitoring fair value without cost. A portfolio schedule showing only fair value hides which positions have actually been marked up.
• Reporting an average instead of a distribution. Private portfolios are concentrated by design, so a portfolio-level average conceals exactly the information that matters.
• Collecting data nobody acts on. If a metric never changes a reserve, a mark or a message to investors, the collection cost is pure overhead.
• Waiting for a quarter close to learn about runway. Cash is the one number that should not travel on a quarterly cycle.

Adjacent terms

Portfolio marking is the output of monitoring: the quarterly carrying value that ends up in every capital account statement and every performance figure. Fair value is the standard those marks are held to, and the reason the basis for each mark has to be stated rather than implied. Net asset value is the aggregate, and it is only as good as the weakest position estimate underneath it.
