Walk Me Through an LP Portfolio Sale: Discount-to-NAV Math

Introduction

The prompt joins two questions that interviewers grade differently. "Walk me through an LP portfolio sale" tests sequence: whether a candidate can take a limited partner (LP) from the decision to sell to cash in hand without skipping the stages where sales stall. "The discount-to-NAV math" tests conventions: what a bid of 90 is 90% of, what it leaves out, and how it becomes a cheque. The halves meet at a single point, the reference date, which the process fixes at launch and every later calculation depends on: net asset value (NAV) at that date is the denominator of every bid, cash that moves after it adjusts the price, and value that changes after it belongs to the buyer. Private capital advisory (PCA) desks that run LP-led sales treat this as their anchor technical question, as the PCA interview format notes, because it compresses their daily work into a few minutes.

A clear answer follows the sale timeline, because each stage creates the input the next one needs. The seller's motive shapes the perimeter, the perimeter and reference date define what buyers bid on, and the bids decide what the purchase agreement has to settle. Six stages carry the answer, each worth two or three spoken sentences:

Spoken at that density, the sequence runs about two minutes and leaves the arithmetic for the follow-up.

Why the Seller Sells and What It Prepares

The opening stage names the seller's motive in one clause, because it explains what the seller will trade away later. An overallocated pension working to a board deadline values certainty of closing, a seller pruning its manager roster values breadth, and one testing the market may pull the sale if bids land below its own view of value. The full list of motives lives in why LPs and GPs need liquidity; the answer needs one, tied to the seller's constraint.

Preparation follows. The seller and its advisor choose the sale perimeter, assemble a data book from capital account statements, cash flow histories and whatever portfolio detail each GP allows buyers to see, fix the reference date (normally the latest quarter-end with GP statements), and sound out each GP on consent before launch. The LP portfolio sale process works through each choice; the answer needs why each one matters, not the checklist.

The Auction and What a Bid Is Quoted Against

Most LP-led volume runs through an advisor-led auction. Buyers receive the data book and submit indicative bids fund by fund; a shortlist gets deeper diligence on the largest holdings and a draft PSA, then submits binding bids. Each bid is a percentage of a fund's NAV at the reference date, so a buyer saying "90" on a fund with $60 million of reference NAV is offering $54 million for that NAV before any adjustment. The percentage survives even among buyers who doubt the marks, because it lets bids on dozens of funds from different managers line up, a tension explained in how fund NAV is set.

This stage also shows the advisor's judgment: reading first-round bids for coverage and dispersion, choosing between one whole-portfolio bid and a combination of fund-level bids, and ranking offers on cash value rather than headline.

Signing, Consents, Closing and the Unfunded

Once winning bids are chosen, the seller signs a PSA with each buyer. The GP signs none of it, but the transfer needs its consent under the fund's limited partnership agreement (LPA), and a right of first refusal can take a fund away from the auction winner after signing, which is why large portfolios often close in stages, as transfer mechanics, GP consent, and the purchase agreement explains. The PSA also turns the percentage into cash. A form of purchase agreement that Ares Private Markets Fund filed with the Securities and Exchange Commission (SEC) shows the usual price convention: a base price tied to a cut-off date, increased by capital the seller funds after that date and reduced by distributions it receives, with the buyer assuming the obligation to make further capital contributions. Stating that convention before any arithmetic is most of the math half.

The last stage is the one most answers drop. The unfunded commitment, capital promised to the fund but not yet called, transfers with the interest: the buyer pays for the NAV and then funds every later call in full. Until each fund closes, the seller remains the LP of record and must meet its calls, which the adjustment reimburses, so a seller raising cash needs liquidity to cover calls until the slowest consent arrives.

Five calculations cover what LP-led interviewers ask, and one illustrative portfolio carries most of them: a pension selling three fund interests with $90 million of NAV at a December 31 reference date. The largest, Fund A, is a 2019-vintage buyout interest with $60 million of reference NAV and $15 million of unfunded commitment, and the lead portfolio bidder offers 90% for it. Every figure is illustrative, and fees and taxes are ignored.

From a 90% Bid to the Closing Payment

Start with the bid: 90% of $60 million is $54 million. Closing takes place the following July, and in between Fund A's GP calls $4 million, which the seller pays, and distributes $9 million, which the seller receives. Calls are added back and distributions deducted, dollar for dollar, in millions:

The seller receives $49 million at closing, and the buyer takes over the remaining unfunded commitment of $11 million, the original $15 million less the $4 million already called.

Purchase Price Adjustment (Secondaries)

The difference between the agreed price for a fund interest and the cash paid at closing, calculated from capital calls the seller funded and distributions it received after the reference date. Calls increase the payment and distributions reduce it, both at full value, so the seller's net proceeds across the period equal the agreed price.

The check that proves the answer is the seller's net position: it paid $4 million in, took $9 million out and receives $49 million, a net $54 million, exactly the bid. The adjustment changes the timing of the seller's cash, not its economics. The fuller treatment, including what happens when the GP remarks the portfolio before closing, is in pricing LP interests and the discount to NAV.

What a 90% Bid Implies

A 90% bid is a 10% discount to NAV: the buyer pays 90 cents for each dollar of the GP's reference-date mark, a $6 million gap on Fund A. Most candidates stop there. The other half is the unfunded commitment, which the buyer funds at 100 cents whenever the GP calls it.

Total Exposure (Fund Interest)

An investor's NAV in a fund plus its remaining unfunded commitment, the full amount it has at stake in that fund on a given date. In a secondary purchase the buyer's outlay is the price for the NAV plus every later capital call, so a bid can also be read as a share of total exposure.

Institutions report their programs on this basis: for the California Public Employees' Retirement System (CalPERS), Meketa's review of the private equity program as of December 31, 2019 put total exposure, defined as NAV plus unfunded commitments, at $44.7 billion against $26.1 billion of NAV. For Fund A, exposure at the reference date is $75 million, the $60 million of NAV plus $15 million unfunded. If every unfunded dollar is eventually called, the buyer's outlay is $69 million, the $54 million price plus $15 million of calls, or 92% of exposure. The same $6 million discount is 10% of NAV but only 8% of the capital the buyer puts to work, which is why a young interest with a large unfunded balance tends to draw a lower headline for the same economics. Market statistics take the buyer's side of this too: Evercore's 2025 secondary market report measures transaction volume as purchase price plus unfunded commitments.

Working Backward From a Target Return

Buyers do not start from NAV and subtract a discount; they forecast cash, discount it at a target return and divide by NAV so that bids compare. A second, simpler interest shows the method: a late-life buyout interest, fully called, with $25 million of reference NAV and two companies left. The buyer expects $12 million of distributions at the end of year one and $18 million at the end of year two, $30 million in all, and underwrites to an illustrative 20% gross return, a round rate chosen for mental arithmetic. In millions:

The price is $22.5 million, or 90% of NAV. Two cross-checks keep the answer honest. The buyer receives $30 million for $22.5 million, a multiple of about 1.33x; a buyer that also insisted on 1.5x would cap its price at $20 million, 80% of NAV. And if the buyer expected exits exactly at the mark, $10 million and $15 million, the same target would give about $8.33 million plus $10.42 million, or $18.75 million, a 75% bid that earns the buyer its 20% a year and nothing more. How buyers build such forecasts is covered in how secondary buyers underwrite a fund interest, and round-rate discounting is practised in mental math for investment banking interviews.

Putting a Deferred Headline on a Cash Basis

A rival buyer bids 93% for Fund A, $55.8 million, but pays $33.8 million at closing and $22 million a year later, without interest. Its value depends on the rate at which the seller discounts the deferred payment: the seller's own cost of capital plus a spread for the buyer's credit, not the buyer's target return. At an illustrative 10%, the deferred $22 million is worth $20 million today, so the bid is worth $53.8 million, about 89.7% of NAV and $0.2 million less than the cash offer. The break-even rate is about 8.9%; below it the deferral wins. The adjustment for calls and distributions applies equally to both bids, so it does not change the ranking.

Which rate to use, and what guarantees or security make a deferral acceptable, are compared in deferred payments and structured pricing tools.

A portfolio bid is quoted as one blended percentage, and the blend is weighted by NAV, not averaged across funds. The pension's three interests show why, with the portfolio bidder's fund-level prices beside the best bid each fund drew on its own:

The portfolio bid is 90% of 60 plus 80% of 20 plus 70% of 10, or $77 million on $90 million, 85.6%. A simple average of the three percentages gives 80%, which understates the offer by more than five points because it gives the smallest fund the same weight as the largest.

Taking the best bid for each fund instead produces a mosaic worth $79.2 million, 88.0% of NAV and $2.2 million more. The gain comes from matching each fund with the buyer whose required return on it is lowest: the holder of the GP's earlier funds knows Fund A best, and the specialists price growth companies and small, old positions with more confidence than a generalist. Against the gain sit three purchase agreements instead of one, more consent risk, and the chance that a conditional piece fails and must be resold. Whether $2.2 million survives those costs is the judgment mosaic bids and portfolio construction puts into numbers, and a sound answer names both sides.

The six stages hold for every LP-led sale; the emphasis moves with what is being sold, and fund age is the clearest dividing line. In Jefferies' July 2026 secondary market review, LP portfolios averaged 87% of NAV, funds under five years old priced at single-digit discounts and tail-end funds over ten years old at discounts of 25% or more, figures set against other surveys in LP-led pricing trends by strategy.

Tail-End Portfolios

A tail-end interest sits in a fund past its original term, with a few companies left and a fixed holding cost that grows against every shrinking dollar of NAV. The answer shifts toward the buyer's short horizon: the late-life example above earned 20% a year at only 1.33x, so a tail buyer judged on multiples bids lower than one judged on annual returns. Sellers often bundle tails into a separate sale for specialist buyers, the route described in tail-end portfolios and fund wind-downs.

A Single Fund Interest

A single-interest sale often runs bilaterally or as a small auction among buyers that already hold the fund or the manager's earlier vehicles, since they can price quickly from their own records. Concentration changes the math: without diversification the buyer underwrites the top holdings almost as direct investments and usually asks a somewhat higher return, so the same fund can price lower alone than inside a portfolio. Consent weighs more as well, because one refusal ends the whole sale.

A Structured Sale

In a structured sale, the seller moves its interests into a new vehicle, a buyer provides cash through preferred equity repaid first from distributions, and the seller keeps the residual. The discount-to-NAV question partly disappears, because the seller never fixes a price on the whole portfolio; in its place come the preferred return, the cash raised as a share of NAV, and what the residual is worth if distributions disappoint. Preferred equity and structured fund solutions sets out the instrument.

Follow-ups probe whichever stage or calculation sounded thinnest, and each deserves a sentence or two of reasoning rather than a rehearsed paragraph:

"Is 90 good?" rewards the most care: ninety may be weak for a young buyout fund with recent marks, strong for a venture fund on stale round prices, and worth less than eighty-eight in cash if it carries a large deferral. Rehearsing alongside walk me through a continuation vehicle sharpens both answers, since interviewers often ask how the two differ: in an LP-led sale the seller initiates at arm's length, and no party sits on both sides of the price.

Most weak answers get the stages roughly right and lose credibility on the numbers, the pattern behind many of the most common investment banking interview mistakes. Five errors recur, each visible in the pension example:

Each number in the walkthrough also has a direction it must move, and checking it takes seconds. The closing payment sits below the bid whenever distributions since the reference date exceed calls, as they did for Fund A. Price as a share of total exposure sits above price as a share of NAV whenever a below-par bid leaves any commitment unfunded. A blended bid lands between the highest and lowest fund-level prices, pulled toward the largest fund. A deferred bid is worth less than its headline at any positive discount rate, and a reverse-engineered price falls when the target rises or the cash arrives later. When every figure points the right way, the answer shows the conventions as well as the arithmetic, and a slip surfaces before the interviewer has to find it.
