Admitted on One Date, Counted From Another.

A fund holds its first close in June and its second the following March. The investor admitted in March signs in March and wires in March. The economics it receives are dated to June. Its share of what the fund has already bought, the expenses already incurred, the clock its preferred return runs on — all of it is calculated from a date nine months before it became a partner.

The cash side of that arrangement is well covered: the incoming investor makes an equalization payment with interest on top, and the money is either distributed to the partners who were already there or applied among the fund's vehicles to adjust their relative participation (§5.1.5). Behind that payment sits an accounting instruction, and it forces the fund to hold two dates at the same time.

The instruction was in the agreement already

ILPA’s model limited partnership agreement is direct about the effect. A partner admitted at a subsequent closing “shall be treated as if it has been admitted … at the Initial Closing Date” (§5.1.1). It participates in “the Portfolio Investments made and Fund Expenses incurred before its admission” pro rata (§5.1.4) — the investments and expenses specifically, not every call the fund ever issued. The general partner then “shall amend Schedule 1 (Partner Commitments) and books and records of the Fund” to reflect the admission (§5.1.3), and “shall appropriately adjust the Partners’ Capital Contributions, Sharing Percentages and Remaining Commitments and any other relevant items,” with the new partner’s preferred return calculated “from the date as if it had been admitted at the Initial Closing Date” (§5.1.6).

None of that touches the Register. Under §2.4 the Register holds the name, contact details and commitment amount of each investor, and the model says plainly that it “shall not be part of this Agreement.” The commitment update lands in Schedule 1. Capital Contributions, Sharing Percentages, Remaining Commitments and the other adjustments belong in the fund’s books and records — the more demanding place for them to live, because books carry dates and a schedule of commitments does not.

The window is bounded. The model defines the Final Closing Date as twelve months from the initial close, so the gap between when an investor is admitted and when its economics are dated cannot exceed a year under this document. A short window, and a crowded one — it spans the period in which a fund makes its earliest investments and issues its first drawdowns.

The economic rule was already there

A change with that reach might be expected to arrive through the agreement’s amendment machinery, and part of it does. Article 19 is where terms change, and reaching the economic ones is hard — modification requires the general partner plus 75% in Interest (§19.1), and an amendment that adversely affects a limited partner by modifying the distributions and allocations article requires the written consent of each affected investor (§19.3.5).

The subsequent closing does amend Schedule 1, and Article 19 expressly permits the general partner to make that update without limited-partner consent (§19.2.5). What it does not amend is the economic rule. The clause requiring the adjustment was already in the agreement. The schedule changes; the rule does not.

The distinction is worth holding precisely, because it is easy to overstate. Nothing in the fund’s history is erased. The calls went out at the rates they went out at, on the dates they went out. Distributions already paid stay paid — the narrow, capped routes by which distributed cash can come back sit elsewhere in the document and are triggered by different events entirely. What the agreement constructs is a counterfactual position, laid over transactions that stay exactly where they were.

Three dates for one event

The records therefore have to distinguish three things: the legal admission date, the deemed economic date and the posting date. Fund accounting systems can be designed to carry all three, along with adjustment entries showing what was posted when. A fund whose books hold all three can answer a question about a pre-admission quarter directly, naming which basis the answer is on. Where entries carry a single date per line, the rest has to be reconstructed from the closing dates and the drawdown history.

The model says what has to be adjusted. It says nothing about how that adjustment should be dated in the books, and nothing about preserving what a figure looked like before. Those are choices in the fund’s system and posting design, not rules supplied by the agreement.

The closing carries two dates: when the investor entered and when its economics begin. Recording the adjustment adds a third: when the entries were posted. Whether a fund’s records keep all three attached to the same event is a design decision, and later questions about that period may turn on which date the answer uses.
