Working definitions from fund formation practice, plain spoken and annotated with our own notes from doing the work.
2 and 20Economics & Fees
Shorthand for the classic hedge fund (and PE) fee model: 2% annual management fee and 20% performance compensation. Market medians are now below it (roughly 1.5 and 17–20 depending on strategy and size).
3(c)(1) ICA §3(c)(1) (15 U.S.C. §80a-3(c)(1))Regulatory
Excludes a fund with no more than 100 beneficial owners (up to 250 for qualifying venture capital funds of limited size) that does not publicly offer its securities. Look-through rules apply to certain entity investors formed to invest in the fund.
Why investors care: The 100 slots are scarce: sponsors ration small commitments, and side-by-side 3(c)(7) vehicles exist because the slots are exhausted.
3(c)(7) ICA §3(c)(7) (15 U.S.C. §80a-3(c)(7))Regulatory
Excludes a fund owned exclusively by 'qualified purchasers' with no public offering. No 100-investor cap, though funds stay under 2,000 holders of record to avoid Exchange Act §12(g) registration.
Why investors care: The institutional standard: larger funds are almost always 3(c)(7). The constraint is investor eligibility; every investor must be a QP, which excludes smaller individuals.
§245A participation exemption IRC §245ATax
A 100% dividends-received deduction letting a U.S. C-corporation receive the foreign-source portion of dividends from a ≥10%-owned 'specified 10-percent owned foreign corporation' free of a second U.S. corporate tax, subject to a one-year holding period and the hybrid-dividend / §245A(e) limits.
Why investors care: Lets a U.S. blocker repatriate qualifying foreign earnings without a second U.S. corporate tax; note the NCTI (formerly GILTI) / Subpart F overlay; the exemption is unavailable where the sub is a PFIC that is not also a CFC.
§475(f) mark-to-market Trader mark-to-market election (IRC §475(f))Tax
A fund that qualifies as a 'trader' (rather than an 'investor') may elect to mark its securities to market at year-end: gains and losses become ordinary, so the capital loss limitations do not apply to the marked positions, and long-term capital-gain rates are forfeited. Under the §475(d)(1) coordination rules the §1091 wash-sale rules do not apply to losses under the regime, while the §1092 straddle rules continue to apply. Due by the prior-year unextended return date for an existing taxpayer; a new taxpayer elects in its books and records within 2 months and 15 days of the start of the election year (Rev. Proc. 99-17). Continues until properly revoked under the current procedures.
Why investors care: A timing and character choice for high-turnover or loss-prone trading books; most equity strategies prefer capital treatment.
506(b) Rule 506(b) (17 C.F.R. §230.506(b))Securities & Offering
The traditional private placement: unlimited accredited investors, no general solicitation or advertising, investors self-certify accreditation. Technically allows up to 35 sophisticated non-accredited investors, which private funds do not use in practice.
Why investors care: The no-general-solicitation condition is why fund marketing is invitation-only and why a manager's public statements during fundraising are reviewed by counsel.
506(c) Rule 506(c) (17 C.F.R. §230.506(c))Securities & Offering
Permits general solicitation (public advertising of the offering) but requires the issuer to take reasonable steps to verify accreditation, not mere self-certification. Under the SEC staff no-action letter to Latham & Watkins (Mar. 12, 2025), high minimum investments (at least $200,000 for individuals / $1,000,000 for entities) plus written representations (accredited status; minimum not third-party financed) satisfy reasonable steps absent contrary knowledge; the documentary methods (tax returns, brokerage statements, professional letters) remain available otherwise.
Why investors care: The verification burden historically led institutional funds to 506(b); the Mar. 2025 staff letter removes most of that burden for funds with institutional-size minimums, making 506(c) a practical choice for managers who want to speak publicly while raising.
§871(m) dividend equivalents IRC §871(m)Tax
Treats payments on total-return (and other delta-one) swaps and certain options that reference U.S. equities as U.S.-source 'dividend equivalents': FDAP subject to 30% withholding (treaty-reducible) for non-U.S. holders, even though no actual dividend is paid.
Why investors care: Reaches synthetic equity exposure that would otherwise avoid dividend withholding; delta-one instruments are squarely in scope.
§892 IRC §892, the sovereign exemptionTax
Exempts foreign governments (including sovereign wealth funds) from U.S. tax on income from stocks, bonds and other securities. Does not cover income from commercial activities or from controlled commercial entities, nor gains from USRPIs held through a controlled commercial entity.
Why investors care: Sovereign investors negotiate to preserve §892: they require structures that avoid commercial-activity taint (separate vehicles, percentage caps, no control positions) and often get bespoke side-letter protections.
Also: sovereign immunity, SWF
§962 election IRC §962Tax
Lets an individual U.S. shareholder of a CFC elect to be taxed at corporate rates on Subpart F / NCTI inclusions, claiming the §250 deduction and an indirect §960 foreign tax credit. The previously-taxed earnings are taxed again as a dividend on actual distribution, but only to the extent they exceed the §962 tax. Made annually.
§1061 Carried interest 3-year ruleTax
For carry holders, long-term capital gain treatment on applicable partnership interests generally requires a more-than-3-year holding period (instead of 1 year); shorter-held gains are recharacterized as short-term.
Why investors care: Affects GP behavior at the margin (hold periods, sale timing) and adds K-1 reporting complexity; investors' main concern is that it not distort exit timing.
Also: carried interest tax
§1446 withholding IRC §1446(a)Tax
A partnership with ECI must withhold tax on each foreign partner's allocable share at the highest applicable rate, regardless of whether cash is distributed.
Why investors care: Means foreign investors in an ECI fund suffer withholding on phantom income; a further reason to use blockers.
§1446(f) withholding IRC §1446(f)Tax
On a transfer of an interest in a partnership engaged in a USTB, the buyer generally must withhold 10% of the amount realized unless an exception certificate applies.
Why investors care: Adds closing mechanics and escrow requirements to secondary sales of fund interests; one more reason secondary transfers in ECI funds are more complex.
§4943 excess business holdings IRC §4943Tax
Limits how much of a business enterprise a PRIVATE FOUNDATION (plus its disqualified persons) may own: generally ≤20% (35% where unrelated parties control), with a 2% de minimis and a five-year disposition period for qualifying gifts and bequests (extendable by up to five more years where the statutory conditions are satisfied). Excess holdings draw an excise tax.
Why investors care: A private-foundation LP can be attributed a fund's holdings in a controlled operating company, so funds with foundation investors confirm status or size participation.
§7874 anti-inversion IRC §7874Tax
Polices transactions where a foreign entity acquires a U.S. corporation (or its assets) while the former U.S. owners keep a large continuing interest: ≥80% continuity treats the foreign 'parent' as a U.S. corporation; ≥60% denies inversion benefits. A substantial-business-activities test is the main exception.
Why investors care: Relevant when a foreign parent sits over a controlled U.S. business; confirm the ownership-continuity fractions before relying on the foreign entity for U.S. tax.
Accredited investor Securities Act Reg D, Rule 501(a) (17 C.F.R. §230.501)Regulatory
The Reg D eligibility baseline: individuals with $1M+ net worth (excluding primary residence) or $200K/$300K (joint) income, certain licensed professionals, knowledgeable employees, and entities meeting asset tests. Nearly all private fund offerings are limited to accredited investors.
AIFMD EU Alternative Investment Fund Managers Directive (2011/61/EU)Regulatory
The EU regime for managing and marketing alternative funds. Non-EU managers marketing into Europe generally use country-by-country national private placement regimes (NPPRs), with registration, Annex IV reporting and, in some states, depositary-lite requirements, since the third-country passport never activated.
Why investors care: The practical question is which EU countries justify the NPPR cost. Germany and Denmark are costly; reverse solicitation is narrow and should not be relied on.
AIV Alternative Investment VehicleStructures & Vehicles
A vehicle the GP may form per the LPA for a specific deal whose structure does not suit the main fund, e.g., routing a U.S. operating investment through a blocker AIV for foreign/tax-exempt investors. Same economics, deal-specific structure.
AmendmentsGovernance & Terms
LPA amendments typically require GP plus majority-in-interest consent, with higher thresholds (or per-investor consent) for economics, liabilities and commitment changes, plus GP-unilateral amendment rights for ministerial or tax/regulatory matters.
Why investors care: Investors scrutinize the GP's unilateral amendment power and 'adverse effect' carve-outs; a broad one can undermine the other protections they negotiated.
American waterfall Deal-by-deal waterfallEconomics & Fees
Carry is calculated and paid on each realized deal (after returning that deal's capital, fees and usually realized losses), long before the whole fund's capital is back.
Why investors care: Investors dislike it: the GP is paid early on successful investments and may owe a refund if later investments lose value. Hence escrows, interim clawbacks and guarantees accompany it. Defended by GPs as necessary to pay deal teams through a long fund life.
AUM Assets Under Management (commercial / marketed)Regulatory
The figure a manager markets and bills on, which is NOT the same as RAUM. Commercial AUM is usually NET of fund-level leverage and liabilities, often reflects only called / invested capital or net asset value, and may exclude proprietary or non-fee-paying accounts. RAUM, by contrast, is gross, includes uncalled commitments, and includes those accounts. Registration thresholds run on RAUM, so a manager can fall below its marketed AUM yet above a RAUM threshold (or the reverse).
Also: Assets under management
Bad actor disqualification Rule 506(d) (17 C.F.R. §230.506(d))Securities & Offering
Rule 506 is unavailable if the issuer or 'covered persons' (GPs, directors, executive officers, 20% holders, promoters, paid solicitors) have disqualifying events: criminal convictions, SEC orders, bars. Hence the bad-actor questionnaires that covered persons complete.
BEAT Base Erosion and Anti-Abuse Tax (IRC §59A)Tax
A minimum tax on large corporate groups (averaging ≥ $500M of gross receipts) that make deductible 'base-erosion' payments to foreign related parties, recomputing tax with those deductions added back at a set rate.
Why investors care: Relevant to a U.S. blocker in a large group that pays deductible interest to a non-U.S. lender: a leveraged blocker's earnings-stripping deduction can be a base-erosion payment.
Blocker Blocker corporationTax
A corporation (U.S. or offshore) inserted between tax-sensitive investors and an investment so that UBTI/ECI 'stops' at the corporate level: the investor receives dividends or share gains rather than a flow-through allocation. UBTI is the tax-exempt investors' problem; ECI is the non-U.S. investors' problem. A corporate blocker solves both, but how much tax the corporation itself pays depends entirely on whether the underlying activity produces ECI.
Why investors care: Three cases. (1) UBTI only, e.g. leveraged securities trading: the §864(b)(2) trading safe harbor keeps the activity from being a U.S. trade or business, so an offshore blocker eliminates the exempt investors' §514 debt-financed UBTI while itself paying essentially no U.S. income tax; this is the efficient case. (2) ECI: operating businesses, loan origination, active real estate: the blocker pays U.S. corporate tax (21% plus state) and, if foreign, potentially the 30% §884 branch-profits tax; a U.S. blocker is usually the less costly form. (3) Both, common in private equity (e.g. a leveraged pass-through operating company): the blocker absorbs the UBTI and the ECI and pays corporate tax; negotiations focus on who bears that leakage and whether exits can be structured as blocker-stock sales.
Also: blocker corp
Blue sky filingsRegulatory
State-level notice filings (and fees) for Reg D offerings: preempted substantively by federal law for Rule 506 offerings but still requiring Form D notice filings in each state where sales occur.
Branch profits tax IRC §884Tax
A second-layer 30% tax (treaty-reducible) on a foreign corporation's DIVIDEND EQUIVALENT AMOUNT: effectively connected earnings and profits reduced by earnings reinvested in U.S. net equity (and taxed later when that equity is withdrawn), approximating the dividend withholding a U.S. subsidiary's shareholder would bear. Key input when comparing U.S. vs. offshore blocker leakage.
CAMT Corporate Alternative Minimum Tax (IRC §55)Tax
A 15% minimum tax on the adjusted financial-statement (book) income of corporations whose AFSI averages over $1 billion across three years (aggregated with the related group).
Why investors care: For very large blockers it sets a 15% floor on BOOK income, eroding the benefit of a leveraged or depreciation-heavy blocker whose taxable income is far below its book income.
Capital call DrawdownEconomics & Fees
The GP's demand that investors fund a portion of their commitment (typically on 10 business days' notice) for investments, fees or expenses. The defining mechanic of closed-end 'drawdown' funds.
Carried interest Carry / promote / incentive allocationEconomics & Fees
The GP's share of profits, classically 20%, allocated through the distribution waterfall after investors receive capital back and (usually) a preferred return. Taxed as the underlying gains (subject to §1061's 3-year rule).
Why investors care: Investors accept carry as alignment; the negotiation is about when it is paid (waterfall type), on what basis (with/without fee-and-expense return), and how over-distributions are returned (clawback).
Also: promote, carry
Catch-up GP catch-upEconomics & Fees
After the pref is paid, a tier in which the GP receives most or all distributions (100% market in buyouts; 80% or 50% are investor-favorable) until it has received its full carry percentage of profits, making the pref a hurdle rather than a permanent concession.
Why investors care: A 100% catch-up means the pref only matters if the fund only narrowly exceeds it; investors negotiating a slower catch-up obtain real economic value.
Cayman vehicles Cayman exempted company / exempted limited partnership (ELP)Structures & Vehicles
The dominant offshore jurisdiction: the ELP mirrors Delaware LP mechanics for offshore funds; the exempted company serves as blockers and corporate feeders. No Cayman tax; CIMA registration under the Private Funds Act now applies.
CFC Controlled Foreign Corporation (IRC §§951–965)Tax
A foreign corporation more than 50% owned (vote or value) by 10%-U.S. shareholders. Such shareholders include Subpart F income and NCTI (formerly GILTI) currently, whether or not distributed.
Why investors care: Fund structures watch ownership percentages so offshore blockers do not inadvertently become CFCs for large U.S. investors; CFC status can be worse than the PFIC regime it displaces.
Check-the-box Entity classification election (Treas. Reg. §301.7701-3, Form 8832)Tax
Most non-per-se business entities can elect their U.S. tax classification: corporation, partnership, or disregarded entity. A central tool of fund structuring: a Cayman company can be a partnership for U.S. purposes, a Lux S.à r.l. can be disregarded, etc.
Clawback GP clawbackEconomics & Fees
The GP's obligation to return excess carry at the end of the fund (or at interim true-ups) if cumulative distributions gave it more than its bargained percentage, usually net of taxes deemed paid.
Why investors care: Investors insist on it whenever carry can be paid early, and negotiate the supporting credit: escrowed carry, interim clawbacks, and personal guarantees from the carry recipients (the GP entity itself is usually thinly capitalized).
Closed-end fund Drawdown fundStructures & Vehicles
Fixed term, committed capital drawn over time, no redemption rights; liquidity comes from distributions as assets are realized. The PE/VC/real estate standard, defined by the capital call and waterfall mechanics.
Co-investmentGovernance & Terms
Investing alongside the fund in a specific deal, usually through a GP-controlled vehicle at reduced or no fee/carry, offered to large or strategic investors when a deal exceeds the fund's concentration limits.
Why investors care: Investors value co-investment (it lowers their effective fees); the points of negotiation are allocation policy (who is offered), expense sharing (especially broken-deal costs), and timing obligations.
CommitmentEconomics & Fees
The maximum capital an investor has contractually agreed to fund over the fund's life, called over time rather than paid upfront. Fund 'size' references aggregate commitments.
Composite return / nonresident withholdingTax
A pass-through fund's income is sourced to the states where it is earned; the states where it has nexus generally require it to file composite returns for, or withhold tax on, the distributive shares of nonresident investors.
Why investors care: A compliance and cash-flow item layered on top of the federal analysis, built into the fund's tax provisions and investor reporting.
Conflicts of interestGovernance & Terms
Transactions where the GP's interests diverge from the fund's: affiliate transactions, cross-fund investments, fee arrangements, allocation of opportunities, GP-led secondaries. The LPA's answer is disclosure plus LPAC consent.
Continuation vehicle GP-led secondaryStructures & Vehicles
A new fund formed to buy one or more assets from an end-of-life fund, managed by the same GP; existing investors choose to sell (liquidity) or roll. Now a major exit route, with built-in conflicts (GP on both sides) addressed through LPAC consent, fairness opinions and competitive processes.
Why investors care: Investors scrutinize pricing (the GP organizes the sale of its own asset) and rolled carry treatment, and ILPA's guidance asks for status-quo rolls as the default.
CPO / CTA Commodity Pool Operator / Commodity Trading Advisor (CEA; 17 C.F.R. §4.13)Regulatory
Operating a fund that trades commodity interests (futures, most swaps, certain FX) makes the GP a CPO by default, requiring CFTC registration and NFA membership, unless an exemption applies: Rule 4.13(a)(3) de minimis (≤5% margin / ≤100% notional) or Rule 4.7 relief for QEP-only funds.
Why investors care: The annual 4.13(a)(3) reaffirmation and the de minimis math on hedging programs are routine compliance risks; investors' counsel checks which exemption is claimed.
CrystallizationEconomics & Fees
The point at which a hedge fund's incentive allocation is measured against the high-water mark and becomes fixed, commonly annually, sometimes quarterly. Until crystallization, accrued incentive can reverse if performance falls back.
Why investors care: Frequency changes the economics materially: under identical return paths, more frequent crystallization locks in incentive on interim gains before later losses, so investors generally prefer annual and managers may prefer quarterly. Structura's open-end analysis models quarterly, semi-annual and annual crystallization at the stated frequency, and a monthly term as quarterly.
Custody rule Advisers Act Rule 206(4)-2 (17 C.F.R. §275.206(4)-2)Regulatory
Reaches an adviser registered or required to be registered under §203 that has custody of client funds or securities. Custody arises three ways: holding the assets, any authority to obtain possession of them, or a capacity such as general partner that gives the adviser or a supervised person legal ownership or access; an adviser also has custody where a RELATED PERSON holds the assets in connection with its advisory services, which is how the ordinary separate-GP structure reaches the rule. A qualified custodian must maintain the assets, and the annual verification is met either by a surprise examination or, the route nearly all funds take, by the audit provision: annual GAAP financials audited under U.S. GAAS by a PCAOB-registered and inspected accountant, delivered to every beneficial owner within 120 days and on liquidation. The audit provision does NOT lift the qualified-custodian requirement.
Why investors care: The practical source of the audited-financials promise in every institutional LPA. Staff have said they would not recommend enforcement where a fund of funds delivers within 180 days, or 260 days for a top-tier fund investing in funds of funds; those are enforcement positions, not terms of the rule.
Debt-financed income (§514) IRC §514, acquisition indebtednessTax
Even passive income (interest, dividends, gains) becomes UBTI in proportion to leverage used to acquire the asset. A fund that borrows, including many subscription-line and portfolio-level structures, can create UBTI from otherwise exempt income.
Why investors care: This is why a 'passive' fund can still produce UBTI for a tax-exempt investor: fund leverage brings exempt investors within §514. Tax-exempt investors ask for leverage covenants, blockers, or §514(c)(9) real estate structuring.
Defaulting LPEconomics & Fees
An investor that fails to fund a capital call. LPAs impose severe (and enforceable) remedies: forfeiture of up to 50% of the interest, loss of voting rights, forced sale, and continued liability.
Why investors care: The severity is deliberate: every other investor depends on calls being funded. Investors negotiate cure periods and sometimes carve-outs for sovereign appropriation mechanics.
Delaware LP Delaware limited partnership (6 Del. C. §17)Structures & Vehicles
The default U.S. fund vehicle: partnership tax treatment, freedom of contract (including fiduciary-duty modification), a deep body of predictable law, and the Chancery courts. Formed quickly; the substantive terms are in the LPA.
DissolutionGovernance & Terms
Early termination of the fund by investor vote (typically 75%+ in interest, sometimes lower if cause exists); the most severe remedy behind removal and suspension rights.
Domestically controlled REIT IRC §897(h)(4)(B)Tax
A REIT less than 50% held (directly or indirectly) by foreign persons throughout the testing period. Stock of a domestically controlled REIT is not a USRPI, so foreign investors can exit FIRPTA-free by selling the stock.
Why investors care: Regulations now look through certain U.S. corporations and partnerships when testing domestic control, so funds must actively monitor and covenant the foreign-ownership percentage.
Downside deviationMetrics & Reporting
The dispersion of returns below a stated threshold, typically the risk-free rate; the denominator of the Sortino ratio.
Why investors care: Separates harmful volatility from harmless upside variation; two strategies with equal total volatility can have very different downside deviations.
DPI Distributions to Paid-InMetrics & Reporting
Cash actually returned ÷ capital paid in: 'realized' performance. The metric experienced investors rely on most, because unrealized value is not cash.
Dry powderMetrics & Reporting
Committed but uncalled capital available to deploy. At the industry level, a gauge of competition for deals; at the fund level, remaining capacity to invest.
ECI Effectively Connected Income (IRC §§864, 871(b), 882)Tax
Income effectively connected with the conduct of a U.S. trade or business. Non-U.S. persons pay U.S. tax on ECI on a net basis at full graduated rates, and must file U.S. tax returns.
Why investors care: Non-U.S. investors avoid ECI for reasons beyond the tax itself: it brings them into the U.S. filing system (often unacceptable to sovereigns and foreign institutions), triggers §1446 withholding, and can expose them to audit. Funds running ECI-generating strategies (loan origination, operating partnerships, U.S. real estate) offer blockers or parallel offshore structures.
Also: effectively connected
Equalization Subsequent-closing true-upEconomics & Fees
Later-closing investors fund their share of existing investments and expenses plus an equalization charge (interest-like, e.g., prime+2%) paid to the first-closing investors, putting all investors in the same economic position as if they had closed together.
ERA Exempt Reporting Adviser (Advisers Act §§203(l), 203(m))Regulatory
An adviser relying on the venture capital adviser exemption or the private fund adviser exemption (<$150M U.S. private-fund RAUM): files an abbreviated Form ADV and is not subject to full registration. Still subject to anti-fraud rules and pay-to-play.
Why investors care: An ERA-managed fund is not compelled to audit by the federal custody rule, which applies to registered advisers, but many state private fund adviser exemptions condition non-venture funds on annual audited financials, and institutional investors expect audits regardless. Funds managed by registered advisers are audited in practice: the custody rule’s alternative, surprise examinations, is not the market route.
ERISA Employee Retirement Income Security Act of 1974 (29 U.S.C. §1104)Regulatory
The federal regime governing U.S. private pension plans, imposing fiduciary duties and prohibiting self-dealing transactions. Funds care because managing 'plan assets' makes the manager an ERISA fiduciary.
Why investors care: Sponsors structure to avoid plan-asset status: ERISA fiduciary duties, prohibited-transaction rules and bonding obligations are incompatible with normal fund operations (carry itself can become a prohibited transaction).
Escrow / holdbackEconomics & Fees
A portion of GP carry distributions (e.g., 20–50%) held in escrow as security for the clawback, released as the fund de-risks.
European waterfall Whole-fund waterfallEconomics & Fees
Carry is paid only after investors have received ALL contributed capital (plus pref) back across the entire fund, not deal by deal.
Why investors care: Investors strongly prefer it: carry comes late and clawback risk is minimal. It is the market standard outside the U.S. and increasingly within it.
Excuse / exclusionGovernance & Terms
Excuse rights let an investor opt out of a specific investment that would violate law or stated policy (common for ERISA, BHC, sovereign and religious-mandate investors); exclusion is the GP excluding an investor for legal/regulatory reasons. Both create per-investor capital account divergence.
Expense allocationEconomics & Fees
Which costs the fund bears (deal expenses, broken-deal costs, fund-level legal, administration, litigation) versus the manager (its own overhead, salaries, rent). A perennial SEC examination priority and a frequent point of negotiation in disclosure.
Why investors care: Investors scrutinize broken-deal allocation between the fund and co-investors, travel policies, and in-house services charged to the fund at 'market' rates.
FATCA / CRS Foreign Account Tax Compliance Act; Common Reporting StandardTax
Parallel U.S. and OECD regimes requiring funds (as financial institutions) to identify and report account holders; FATCA backs this with a 30% withholding sanction. The reason subscription documents demand W-8s/W-9s and self-certifications.
FDAP Fixed or Determinable Annual or Periodical incomeTax
U.S.-source passive-type income (interest, dividends, rents, royalties) of non-U.S. persons that is not ECI. Taxed by 30% gross-basis withholding, reduced or eliminated by treaty or statutory exemptions (e.g., portfolio interest).
Fee base Committed vs. invested capitalEconomics & Fees
What the management fee is charged on: committed capital (the full pledged amount, even if undrawn), invested capital (cost of unrealized investments), NAV (open-end funds), or gross assets. The difference is material: 2% on committed is far more than 2% on invested in the early and late years.
Fee offset Management fee offsetEconomics & Fees
Transaction, monitoring, directors', break-up and similar portfolio-level fees received by the manager are credited (offset) against the management fee, at 100% in today's market.
Why investors care: Anything below 100% is contrary to the ILPA position; investors also scrutinize the definition's breadth (whether it reaches affiliated service providers).
Feeder fundStructures & Vehicles
A vehicle whose only asset is its interest in another fund, existing to give a class of investors the appropriate tax and regulatory wrapper into the same portfolio.
Finder Broker registration: Exchange Act §15 (15 U.S.C. §78o)Securities & Offering
An unregistered intermediary introducing investors for transaction-based compensation; a persistent area of regulatory uncertainty. Paying a finder who should have been a registered broker-dealer can create rescission risk for the offering.
FIRPTA Foreign Investment in Real Property Tax Act (IRC §897)Tax
Treats a non-U.S. person's gain on U.S. real property interests (including most U.S. real-estate-heavy corporations) as ECI, taxable on a net basis, with a 15% gross withholding on disposition under §1445.
Why investors care: Non-U.S. investors avoid it for the same reasons as ECI: U.S. tax plus U.S. filings on what they expected to be a passive investment. Mitigants the market uses: domestically controlled REITs, the §897(l) QFPF exemption, and leveraged blockers.
Fractions rule IRC §514(c)(9)(E)Tax
An exception letting certain qualified organizations (mainly pensions and educational institutions) invest in leveraged real estate partnerships without debt-financed UBTI, but only if the partnership's allocations satisfy a rigid test for the entire life of the fund.
Why investors care: Real estate funds with pension investors devote significant drafting effort to this exception; a single non-compliant allocation (e.g., some preferred returns or fee waterfalls) can defeat the exception for every qualified organization in the fund.
Fund of one / SMA Separately managed accountStructures & Vehicles
A vehicle or account for a single investor, with negotiated strategy, fees and liquidity. Large allocators increasingly use them for control and fee economics; managers weigh the operational load against the relationship.
Fund SPV Single-asset vehicleStructures & Vehicles
An investor-facing vehicle formed to make one identified investment, or a small number of identified investments: a simplified fund. Because the investments are identified when investors commit, it is not a blind pool. Capital is fully applied to the deal at closing (no capital calls for new investments), and most closed-end fund mechanics do not apply: no investment period, no investment limitations, no recycling, and key person usually does not apply. Common in deal-by-deal sponsors, GP-led co-invest syndication and venture SPVs.
Why investors care: Investors weigh the trade-off: full transparency into the single asset and no blind-pool risk, but no diversification, and economics vary widely (flat carry with no pref is common). Because it takes commitments, it still needs an ICA exemption, an offering exemption and (simplified) fund terms; diligence confirms that the sponsor has not treated it as a mere subsidiary.
Also: single asset vehicle, deal-by-deal vehicle, SPV fund
GateEconomics & Fees
A cap on redemptions in any window: investor-level (each investor may redeem only X% of its holding per quarter) or fund-level (total redemptions capped at X% of NAV, pro-rated).
Why investors care: Fund-level gates drew criticism in 2008, when suspensions left investors waiting behind other investors' redemptions; investor-level gates are now the more accepted design because an investor's liquidity does not depend on the queue.
General solicitation Rule 502(c) (17 C.F.R. §230.502)Securities & Offering
Public advertising or communications offering the securities: websites, conferences, press, mass email. Prohibited in 506(b); permitted in 506(c). Pre-existing substantive relationships are the traditional basis for offering without it.
GILTI / NCTI Global Intangible Low-Taxed Income → Net CFC Tested Income (IRC §951A)Tax
A 10%-U.S. shareholder of a CFC includes the corporation's tested income currently. The §250 deduction, 40% for tax years beginning after 2025 (down from 50%), gives a U.S. C-corporation shareholder an effective rate of about 12.6% at the 21% corporate rate (formerly ~10.5%). The 2025 legislation renamed GILTI 'net CFC tested income' (NCTI) and repealed the QBAI tangible-return exclusion from 2026. Rates change; confirm the figure for the relevant year.
Why investors care: The reason a U.S. taxable sleeve through an offshore corporate blocker can face current ordinary inclusions. Mitigants: a pass-through for U.S. taxables, the §250 deduction (corporate shareholder), a §962 election (individuals), or the high-tax exclusion.
GILTI high-tax exclusion Treas. Reg. §1.951A-2(c)(7)Tax
Lets a U.S. shareholder elect to exclude CFC tested income that bears foreign tax above 90% of the U.S. corporate rate (about 18.9% at a 21% rate). Elected annually on a tested-unit basis for the whole controlled group; often the simplest answer for a CFC operating in a meaningful-tax jurisdiction.
GP General PartnerStructures & Vehicles
The fund's controlling partner, bearing (in theory) unlimited liability, so it is always a special-purpose entity (LLC or LP) formed for each fund. Receives the carried interest; the management company (IM) earns the management fee.
GP commitmentEconomics & Fees
The GP's own capital invested in the fund alongside investors: 1–5% of total commitments (2% or more signals commitment; 'GP-friendly' management-fee waivers in lieu of cash are scrutinized).
Why investors care: Investors want it meaningful, in cash, from the individuals (not financed or fee-waived), and invested on the same terms. It is the clearest alignment term.
Also: skin in the game
Gross-to-net spreadMetrics & Reporting
The difference between a fund's gross annualized return and its net annualized return to investors: the total drag of management fees, fund expenses and the incentive allocation.
Why investors care: The clearest single figure for comparing fee structures: two funds with identical gross performance and different terms separate immediately on the spread. The headline comparison figure in Structura's NAV analysis.
High-water markEconomics & Fees
In hedge funds: incentive compensation is only charged on net new profits above the highest prior NAV (per investor), so investors do not pay twice for recovering losses.
Why investors care: Universal investor expectation; the negotiated variants (resets, modified HWMs with reduced-rate recovery) favor the manager and are scrutinized.
HoldCo Holding companyStructures & Vehicles
The top holding entity that owns the operating subsidiaries of a portfolio investment. It carries no fund terms (governance flows from the fund or TopCo above); its functions are structural: locating acquisition debt and guarantees, isolating operating liabilities, providing lenders a single security package, and creating the tax-efficient entry point into the group. Larger capital structures stack HoldCo / MidCo / BidCo layers to tier debt.
Why investors care: Investors and lenders care where the HoldCo sits and what sits at each layer: structural subordination (whose claim is closest to the assets), guarantee scope, and whether dividends can move up through the stack without leakage.
Also: holding entity, midco
Hurdle rateEconomics & Fees
In hedge or open-end funds: a benchmark (fixed % or index) NAV must exceed before incentive fees accrue. The open-end counterpart of the preferred return; 'hard' hurdles pay incentive only on the excess.
ILPA Institutional Limited Partners AssociationGovernance & Terms
The trade association of institutional fund investors (pensions, sovereigns, endowments, insurers). ILPA publishes the market’s reference standards for fund terms and reporting: the ILPA Principles (alignment of interest, governance, transparency), a Model Limited Partnership Agreement, standardized reporting and fee-disclosure templates, and model conventions for specific terms, for example recycling limited to the cost of deals realized within 12 months.
Why investors care: ILPA positions are not law, and they are not the market default: they are the baseline from the investor's side of the table. Institutional LPs cite them in side letters and LPA comments; sponsors typically negotiate from their own precedent and concede ILPA positions selectively, so the agreed terms usually fall between the two. A term drafted far from the ILPA position still draws questions in institutional diligence. Structura labels terms that follow an ILPA formulation, for example the recycling convention limited to deals realized within 12 months, so the source of the convention is visible.
Also: Institutional Limited Partners Association
Incentive allocationEconomics & Fees
The hedge fund manager's performance compensation, structured as an allocation of partnership profits to the general partner's capital account rather than a fee paid by the fund. Typically a percentage of net gains above the high-water mark, measured at crystallization.
Why investors care: The allocation form matters for tax character: an allocation passes through the character of the underlying gains, while a fee is ordinary income to the manager and a deduction question for investors. The closed-end analog is carried interest through a distribution waterfall.
Also: performance allocation, incentive fee
Integration Rule 152 (17 C.F.R. §230.152)Securities & Offering
The doctrine asking whether multiple offerings are in substance one (so that an exemption is tested across them together). Rule 152 now provides safe harbors, but parallel funds, co-invests and successor vehicles are still structured with integration in mind.
Interim clawbackEconomics & Fees
Clawback testing during the fund's life (e.g., after the investment period or on each distribution date) rather than waiting for liquidation, catching over-distributions while the GP still has assets.
Investment Company Act Investment Company Act of 1940 ('40 Act / ICA)Regulatory
The statute regulating mutual funds. Private funds are 'investment companies' by default and must fit an exclusion, almost always §3(c)(1) or §3(c)(7), to avoid a regime they could not practically operate under.
Why investors care: ICA compliance is binary: lose the exclusion and the fund's contracts can be voidable. This is why investor counting and qualified-purchaser status are checked carefully at closing.
Investment period Commitment periodGovernance & Terms
The years (typically 4–6 from final or first closing) during which the GP may call capital for new investments; afterwards, calls are limited to follow-ons, fees and obligations. Triggers the management fee step-down.
IRR Internal Rate of ReturnMetrics & Reporting
The discount rate equating capital calls and distributions over time; the headline private-funds return metric, sensitive to timing (early distributions and delayed calls flatter it).
Why investors care: Investors read IRR alongside multiples because it can be managed: subscription lines delay calls, and early small realizations lock in high IRRs. Hence ILPA's levered/unlevered disclosure initiative.
J-curveMetrics & Reporting
The early-years dip in a closed-end fund's net returns (fees and expenses are drawn while investments are still at cost) followed by the rise as value is created and realized. Subscription lines and early markups flatten (or obscure) it.
K-1 Schedule K-1 (Form 1065)Tax
The annual statement a partnership issues each partner showing their allocable share of income, deductions and credits; the document through which fund tax results reach investors.
Why investors care: Investors object: K-1s often arrive after April 15 (forcing extensions), and a multi-fund portfolio means dozens of them. Funds with many foreign/tax-exempt investors are drawn toward structures that simplify or eliminate K-1s (blockers issue 1099s/dividends instead).
Key person Key man provisionGovernance & Terms
If named principals cease devoting the required time to the fund, the investment period automatically suspends (and terminates absent a vote to restart, or restarts only on LP/LPAC approval with a replacement).
Why investors care: Investors commit to named individuals, not to a firm name. Without a key-person clause, investors are committing capital to whoever manages the fund in the future. Negotiation centers on who is named, the time standard, and whether suspension is automatic.
Knowledgeable employee ICA Rule 3c-5 (17 C.F.R. §270.3c-5)Regulatory
Executive officers and employees who participate in the fund's investment activities (for 12+ months) may invest without being QPs and without counting against the 100-owner limit; the route by which the investment team invests in its own funds.
Lock-upEconomics & Fees
The initial period an investor cannot redeem: 'hard' (no redemption at all) or 'soft' (redemption allowed with an early-withdrawal fee, e.g., 2–5%, usually paid to the fund).
LPA Limited Partnership AgreementGovernance & Terms
The fund's constitution: economics, governance, fiduciary standards, transfer rules, dissolution. Every other document (PPM, side letters, subscription documents) is subordinate to it.
LPAC Limited Partner Advisory CommitteeGovernance & Terms
A committee of (usually 5–9) large investors that consents to conflicts of interest, valuation methodology and other LPA-specified matters. Members act in their own interest, expressly not as fiduciaries for other LPs.
Why investors care: Investors want a seat (information and influence); other investors want assurance that the LPAC cannot waive protections that should require a full vote. Review what the LPA lets the LPAC approve versus all-investor consent.
Also: advisory committee, advisory board
Management feeEconomics & Fees
The annual fee paying the manager's operating costs. Classically 2% (1.5–2% market, lower for large or credit funds) on committed capital during the investment period, stepping down to invested capital (or a lower rate) thereafter.
Why investors care: Investors focus less on the headline rate and more on the base (committed vs. invested), the step-down trigger, offsets, and whether fee income is just covering costs or is itself a profit center. Where the base is invested capital, market definitions vary: commonly the funded cost of unrealized investments (with capitalized transaction expenses), reduced as deals are realized or written off; some LPAs use NAV or reduce the base on significant write-downs. Structura models the funded-cost definition and discloses the variants.
Management fee waiverEconomics & Fees
An arrangement where the GP waives management fees in exchange for a profits interest funding its GP commitment, converting ordinary fee income into capital gain and deferring tax. The IRS has proposed regulations attacking versions lacking entrepreneurial risk.
Why investors care: Investors increasingly resist: a waived-fee commitment is not cash at risk.
Master-feederStructures & Vehicles
One master fund holds the portfolio; investors enter through feeders matched to their tax profile: a U.S. LP feeder for U.S. taxable investors, an offshore corporate feeder for non-U.S. and U.S. tax-exempt investors (blocking UBTI/ECI at the feeder).
Why investors care: The standard hedge fund architecture. The offshore feeder is a PFIC for U.S. taxable investors, which is why they invest through the domestic feeder.
Maximum drawdownMetrics & Reporting
The largest peak-to-trough decline in net asset value over a period, expressed as a percentage of the peak. It measures investment performance, a drop in the value of the portfolio; it is not investor redemptions, and investor redemptions are not modeled.
Why investors care: Institutional investors read it as the loss a strategy can impose: how much an investor at the worst entry point would have lost before recovery. Under a high-water mark, deep drawdowns also stall the manager's incentive until the peak is regained.
MFN Most Favored NationGovernance & Terms
The right to elect side-letter provisions granted to other investors. Almost always tiered by commitment size (you may elect terms given to investors of your size or smaller) and excluding regulatory/tax accommodations specific to an investor's status.
Why investors care: The tiering is the negotiation: a full, untiered MFN is rare and generally limited to anchor investors. Investors also negotiate whether fee discounts granted through separate vehicles fall outside the MFN.
Modified European waterfall Hybrid waterfallEconomics & Fees
A middle form between the European and American waterfalls. In its most common formulation, carry is paid as investments are realized, but only after investors have received back the capital of the REALIZED investments (with the fees and expenses allocated to them) plus the preferred return, rather than all contributed capital.
Why investors care: The label covers a family of negotiated variants rather than one standard: some agreements pay carry per deal subject to an interim clawback, others gate carry on a fair-value or liquidation-value test of the remaining portfolio, and the tests themselves vary. Because there is no single market formulation, the Economic Model prices a fund stated as modified European on the whole-fund European convention, the conservative reading for investor economics; carry under the stated terms would typically flow earlier. The structure itself records the stated term. Consult an attorney and tax adviser on the precise formulation.
MOIC Multiple on Invested CapitalMetrics & Reporting
Total value (realized + unrealized) divided by invested capital: the multiple of capital returned; it is unaffected by timing but does not reflect how long capital was invested.
Monte Carlo simulationMetrics & Reporting
An analysis that runs the same fund model through thousands of simulated market paths and reports the distribution of outcomes (median, percentiles, probabilities) instead of a single number.
Why investors care: The expected-value case is one blended path; the distribution shows the range and the odds. In Structura the simulation is seeded and deterministic: identical assumptions and seed reproduce the identical result, byte for byte, and legal, tax and waterfall rules are never sampled; only market outcomes are.
NAV Net Asset ValueMetrics & Reporting
Assets minus liabilities, at fair value. In open-end funds it is the transaction price for subscriptions/redemptions and the fee base; in closed-end funds, the basis of interim reporting and RVPI.
NAV facilityEconomics & Fees
Borrowing secured by the fund's portfolio value (rather than uncalled commitments), used late in a fund's life for follow-ons, liquidity or, controversially, to fund distributions.
Why investors care: Investors have become cautious: NAV-facility-funded distributions are leverage presented as performance, and ILPA has called for consent or disclosure requirements.
Open-end fund Evergreen / hedge fund structureStructures & Vehicles
No fixed term: investors subscribe and redeem at NAV periodically; capital is fully funded at subscription. Economics run through NAV-based fees and incentive allocations with high-water marks, and liquidity is managed through gates, lock-ups and notice periods.
Opportunity Zone / QOF Qualified Opportunity Fund (IRC §§1400Z-1, 1400Z-2)Tax
A QOF (a corporation or partnership investing ≥90% in qualified opportunity-zone business property) lets investors defer eligible capital gains reinvested within 180 days and, after a 10-year hold, step the QOF interest up to fair market value so post-acquisition appreciation escapes tax.
Why investors care: A real-estate / development overlay that can change the optimal vehicle; mind the semi-annual 90% asset test and the substantial-improvement requirement.
Organizational expensesEconomics & Fees
The costs of organizing and launching the fund, including forming the entities, preparing the fund and offering documents, negotiating fund terms, side letters and closings with investors (legal, accounting, filing), and the marketing of the offering itself, including travel, meals and lodging for management roadshows and investor meetings, which are not legal fees but are customarily borne by the fund as organizational expenses. Costs of the sponsor’s own house are not organizational expenses of the fund: forming the management company, its adviser registration and compliance program, and developing the carried interest program are customarily paid by the manager, and practice varies on the basic formation of the general partner. Fund organizational expenses are borne by the fund up to a negotiated cap, with the excess borne by the manager, typically via a management fee offset. Caps scale with fund size.
Also: org costs
Parallel fundStructures & Vehicles
A companion fund investing side by side with the main fund in fixed proportions, on substantially identical terms; formed for investors needing a different jurisdiction or tax treatment (e.g., an offshore parallel for non-U.S. investors rather than a feeder).
Per se corporationTax
Entity types listed in the regulations that are always corporations for U.S. tax purposes and cannot check the box (e.g., a U.S. Inc., a UK plc, an SA). Choosing a non-per-se vehicle preserves classification flexibility.
PFIC Passive Foreign Investment Company (IRC §§1291–1298)Tax
A foreign corporation that is mostly passive (75% income / 50% assets tests). U.S. taxable investors in a PFIC face a punitive interest-charge regime on 'excess distributions' and gains, unless they elect QEF or mark-to-market treatment.
Why investors care: This is why U.S. taxable investors avoid offshore corporate feeders and blockers (or demand QEF reporting): the default PFIC regime can convert long-term gains into ordinary income plus an interest charge.
Phantom incomeTax
Taxable income allocated to investors without matching cash distributions; common with accrued (PIK) interest, reinvested gains, or §1446 withholding situations.
Why investors care: Investors push for tax distributions so that they do not pay tax from other resources on income they have not received.
Placement agentSecurities & Offering
A registered broker-dealer engaged to raise capital for the fund, compensated by a percentage of commitments raised. LPAs typically offset 100% of placement fees against the management fee so that investors do not bear them economically.
Why investors care: Investors expect the offset and diligence pay-to-play exposure (public pension placements are heavily regulated after the 2009 pay-to-play enforcement matters).
Plan assets / 25% test DOL plan asset regulation (29 C.F.R. §2510.3-101); ERISA §3(42)Regulatory
A fund's assets become 'plan assets' if benefit plan investors hold 25% or more of any class of equity (excluding the GP's and affiliates' interests), unless the fund qualifies as a VCOC or REOC. Tested at every closing and on transfers and withdrawals.
Why investors care: Why LPAs cap benefit plan investor participation, give the GP power to force withdrawals to stay under 25%, and why ERISA investors negotiate for protections if the fund ever does become plan-assets.
Also: significant participation
Portfolio interest exemption IRC §§871(h), 881(c)Tax
Exempts most U.S.-source interest on registered-form debt from the 30% withholding tax for non-U.S. lenders. Unavailable to 10% equity holders, banks on ordinary loans, and contingent interest.
Why investors care: The foundation of foreign investment in U.S. credit: it is why credit funds structure notes carefully and why a foreign investor's percentage interest in a lending vehicle matters.
PPM Private Placement Memorandum; Rule 10b-5 (17 C.F.R. §240.10b-5)Securities & Offering
The fund's disclosure document: strategy, terms, risk factors, conflicts, tax and regulatory discussion. Not reviewed by any regulator; its discipline comes from Rule 10b-5 antifraud liability.
Why investors care: Investors read the conflicts and fees sections (and increasingly, the expense allocation disclosure) most carefully; the remainder is supporting diligence material.
Also: offering memorandum, OM
Preferred return Hurdle / prefEconomics & Fees
The return (8% compounded annually is the PE standard) investors must receive on contributed capital before the GP shares in profits. Credit and real estate funds often run 6–8%; some VC funds have none.
Why investors care: Investors watch the compounding convention (compound vs. simple), what capital it accrues on (all contributions vs. investment cost only), and whether the GP catch-up effectively eliminates it.
Also: pref, hurdle
Prohibited transaction ERISA §406 (29 U.S.C. §1106); IRC §4975Regulatory
Per se bans on transactions between a plan (or plan-asset fund) and 'parties in interest': sales, loans, services, self-dealing, regardless of fairness, subject to statutory and administrative exemptions (e.g., the QPAM exemption).
PTET Pass-Through Entity Tax (state response to the federal SALT deduction limitation)Tax
An elective state tax under which a partnership pays the state income tax at the entity level and deducts it federally. The election can mitigate the federal limitation on individual deductions for state and local taxes. Available in most income-tax states, but not all (e.g., not Pennsylvania or Delaware).
Why investors care: For U.S. taxable fund investors a PTET election can restore a federal deduction for state taxes; weigh it against each state's nonresident-credit mechanics.
QEF election Qualified Electing Fund (IRC §1295)Tax
An election letting a U.S. investor in a PFIC include its share of the PFIC's earnings annually (preserving capital-gain character for net capital gain) instead of the punitive default regime, but only if the PFIC provides the necessary annual information statement.
Why investors care: Investors ask up front: 'will the fund provide PFIC annual information statements?' If not, U.S. taxable investors avoid offshore corporate vehicles.
QFPF Qualified Foreign Pension Fund (IRC §897(l))Tax
Foreign pension funds that are qualified holders under the §897(l) rules are exempt from FIRPTA on U.S. real property gains attributable to qualified segregated accounts; a major carve-out that reshaped foreign pension investment in U.S. real estate.
QSBS (§1202) Qualified Small Business StockTax
An exclusion of gain on the sale of qualifying C-corporation stock held by a non-corporate holder. For stock issued after July 4, 2025, a tiered 50% / 75% / 100% exclusion applies at 3 / 4 / 5-year holding periods, with a per-issuer cap of the greater of $15M (indexed) or 10x basis and a $75M gross-asset ceiling at issuance. §1045 lets a holder roll gain on QSBS held more than six months into replacement QSBS.
Why investors care: A reason a U.S. taxable investor wants to hold C-corp portfolio stock directly or through a flow-through, not through a blocker corporation, which would forfeit the exclusion and add a layer of corporate tax.
Also: qsbs, small business stock, 1202, 1045
Qualified client Advisers Act Rule 205-3 (17 C.F.R. §275.205-3)Regulatory
The standard an investor must meet for a registered adviser to charge it performance-based compensation (carry/incentive fees): currently $1.4M+ under management with the adviser or $2.7M+ net worth (set by the SEC's inflation-adjustment order effective June 29, 2026; adjusted about every five years). QPs and knowledgeable employees qualify automatically.
Why investors care: Mostly invisible in 3(c)(7) funds (every QP is a qualified client) but a real constraint for RIA-managed 3(c)(1) funds admitting investors who are accredited but not qualified purchasers.
Qualified purchaser ICA §2(a)(51) (15 U.S.C. §80a-2(a)(51))Regulatory
Generally: individuals with $5M+ in investments; entities with $25M+ in investments; certain family companies and trusts. The eligibility gate for 3(c)(7) funds.
Also: QP
Random seedMetrics & Reporting
The starting number for the simulation's random-number generator. The generator is deterministic: the same seed with the same assumptions produces the identical set of simulated markets every time.
Why investors care: Reproducibility. A deliverable can state its run identifier and seed, and anyone can reproduce the exact analysis later; changing the seed draws a different, equally valid set of simulated markets, which shows sampling variation rather than a different model. Keep it fixed for client work; vary it to test robustness.
Also: seed
RAUM Regulatory Assets Under Management; Form ADV Part 1A, Item 5.F (Instructions)Regulatory
The SEC's standardized asset measure that drives the adviser-registration thresholds: the $150M private fund adviser exemption, and the $100M / $110M SEC-registration line. It is computed GROSS: fund-level debt and other liabilities are not subtracted, and for a private fund uncalled capital commitments are INCLUDED, plus any proprietary, non-fee-paying or non-U.S.-client assets the adviser manages continuously and regularly. Measured at current market or fair value within 90 days of the filing.
Why investors care: Because RAUM is gross and counts uncalled commitments, a fund can cross a threshold at final close even with little capital deployed; monitor it during the fundraising. Always confirm the calculation with counsel and a tax adviser.
Also: Regulatory AUM
Recycling Reinvestment provisionsEconomics & Fees
The GP's right to reinvest (rather than distribute) certain proceeds, typically capital returned within 12–18 months or up to invested-cost limits, so the fund can deploy approximately 100% of commitments despite fees and expenses consuming part.
Why investors care: Investors accept modest recycling for deployment efficiency but cap it (e.g., 110–120% of commitments) and exclude profits. Definitions vary meaningfully by LPA: the cap and the available capacity may be measured against capital commitments, invested capital, or the cost of realized deals, and recallable amounts often extend past the investment period for follow-on investments; read the measure carefully. Structura’s economic model measures the cap against capital commitments (its ILPA option recovers fees and expenses) and models recall for follow-on draws.
Redemption Withdrawal termsEconomics & Fees
The open-end liquidity package: frequency (monthly/quarterly), notice period (30–90 days), payment timing, holdbacks pending audit, and the GP's suspension powers. Collectively, the real liquidity an investor has.
Why investors care: Sophisticated investors read these together: quarterly liquidity with 90 days' notice, a 25% investor gate and audit holdback is far less liquid than the marketing materials imply.
Reg D Regulation D (17 C.F.R. §§230.500–230.508)Securities & Offering
The safe harbor under which virtually all U.S. private funds offer their interests without SEC registration; in practice Rule 506(b) or 506(c), with a Form D filed within 15 days of first sale.
Reg S Regulation S (17 C.F.R. §§230.901–230.905)Securities & Offering
Safe harbor for offers and sales made outside the U.S. to non-U.S. persons; routinely paired with Reg D so a fund can raise globally in one offering.
REIT Real Estate Investment Trust (IRC §§856–860)Tax
A corporation that, by meeting income, asset, distribution (90%) and ownership tests, deducts dividends paid, leaving effectively one level of tax. Must have at least 100 shareholders (hence the ~125-holder 'accommodation preferred' placements) and not be closely held.
Why investors care: In funds, private REITs are used to block UBTI from debt-financed real estate, simplify reporting (1099-DIV, no K-1), and serve foreign investors, at the cost of REIT compliance overhead.
Removal (for cause / no-fault) GP removalGovernance & Terms
For-cause removal (fraud, willful misconduct, material breach, often requiring a final adjudication) typically needs a majority-in-interest; no-fault removal needs a supermajority (75–80%) and usually leaves the GP with accrued carry and a tail of reduced carry on existing investments.
Why investors care: Investors treat no-fault removal as the final accountability protection. ILPA recommends it; GPs resist or price it via generous removal economics. The 'final adjudication' requirement can make for-cause removal impractical.
REOC Real Estate Operating Company (29 C.F.R. §2510.3-101(e))Regulatory
The real estate analog to VCOC: 50%+ of assets in real estate that is managed or developed, with the entity having the right to participate substantially in management/development. The standard plan-asset route for real estate funds that cannot remain under 25%.
ReportingGovernance & Terms
The information package: annual audited financials (custody rule timing), unaudited quarterlies, capital account statements, K-1s, and increasingly the ILPA reporting and fee templates.
Why investors care: Institutional investors now routinely require ILPA-template fee/expense reporting; transparency here is inexpensive for well-run sponsors, and resistance to it is informative.
RIA Registered Investment Adviser (Advisers Act §203; 15 U.S.C. §80b-3)Regulatory
An adviser registered with the SEC, generally required once a private fund manager has $150M+ in private-fund RAUM (or $100M+ RAUM generally). Registration brings Form ADV, the custody rule, compliance programs, the marketing rule, books-and-records and examinations.
Why investors care: Institutional investors usually prefer (or require) an RIA: the compliance infrastructure and SEC oversight simplify investor diligence. Emerging managers bear the cost; many start as ERAs.
RVPI Residual Value to Paid-InMetrics & Reporting
Remaining NAV ÷ paid-in capital: the unrealized component of TVPI (TVPI = DPI + RVPI).
Season and sellTax
A structure for non-U.S. credit investors: a U.S.-taxed affiliate originates loans (origination is a USTB), holds ('seasons') them for a period, then sells them to the offshore fund, which merely buys seasoned debt and so avoids ECI. Requires that the form be respected in substance: independent decision-making, market terms, no pre-arranged commitment.
Why investors care: Aggressive versions are an IRS focus; investors and their counsel diligence how disciplined the seasoning process actually is.
Sharpe ratioMetrics & Reporting
A risk-adjusted return measure: the portfolio's return in excess of the risk-free rate, divided by the volatility of returns. Higher is better; a ratio near 1 over a full cycle is strong for most strategies.
Why investors care: The most quoted risk-adjusted figure, but it penalizes upside and downside volatility equally. In Structura it is an output computed from the simulated return distribution against the stated risk-free rate, never an input.
Side letterGovernance & Terms
A bilateral agreement giving a specific investor terms beyond the LPA: fee discounts, co-investment rights, excuse rights, reporting, regulatory accommodations (ERISA, §892, public-records laws).
Why investors care: Universal among institutions. MFN provisions distribute most economics anyway, and disclosure norms continue to tighten. Funds maintain compendiums and election processes to administer them.
Side pocketEconomics & Fees
A segregated class holding illiquid positions in an otherwise liquid fund: incoming investors do not share in them, redeeming investors wait for realization, and incentive fees are charged only on realization.
Why investors care: Misuse after 2008, placing losing positions in side pockets, made investors cautious: they negotiate caps (e.g., 10–20% of NAV), designation criteria and fee treatment.
Sortino ratioMetrics & Reporting
A variant of the Sharpe ratio that divides excess return by DOWNSIDE deviation only, the dispersion of returns below the risk-free rate, rather than total volatility.
Why investors care: Often the more relevant figure for hedge funds: investors do not fear upside volatility, so a strategy with occasional large gains is not penalized for them. Structura computes it from the simulated after-leakage distribution.
Special limited partner Special LPEconomics & Fees
A limited partner entitled to the carried interest allocation rather than a pro-rata capital return: a sponsor-side vehicle, commonly a separate entity from the general partner, through which the principals receive the carry. Separating the carry from the general partner keeps the economics apart from management authority and unlimited-partner exposure, and gives the carry program its own vehicle for vesting, transfers and estate planning.
Why investors care: Whether the carry sits in the general partner or a special limited partner changes governance and liability exposure, not the investors' economics: the waterfall pays the same carry either way. Diligence asks who controls the carry vehicle and how departures and transfers are handled.
Also: special LP, carry vehicle
SPV Special Purpose VehicleStructures & Vehicles
A single-purpose entity below the fund: holding companies for deals, leverage isolation, jurisdiction access. In its standard form it is a subsidiary splitter or aggregator (it allocates ownership among vehicles and holds sub-entities) and is not investor-facing, so it carries no fund terms. Fund structures stack SPVs for liability, tax and financing reasons.
Why investors care: A standard SPV differs from a Fund SPV: the standard SPV sits below the fund as a structural subsidiary; a Fund SPV sits above, takes commitments from investors, and needs fund terms and securities exemptions.
Standard of care Exculpation & indemnificationGovernance & Terms
The liability floor below which the GP is not exculpated or indemnified. Market is gross negligence, fraud, willful misconduct and material breach; ILPA pushes for ordinary negligence and express non-waiver of fiduciary duties (Delaware law allows substantial waiver in an LPA).
Why investors care: Investors read the interplay: a broad fiduciary-duty waiver plus gross-negligence exculpation plus fund-paid indemnification means the fund bears nearly all GP errors. The indemnification advance/clawback mechanics matter as much as the standard.
Step-downEconomics & Fees
The reduction in management fee after the investment period (or on a successor fund's first closing): switch the base to invested capital, lower the rate, or both.
Why investors care: ILPA's position: fees should track the actual cost of managing the remaining portfolio, not compensate inactivity.
Subpart F income IRC §§951–964Tax
Specified categories of a CFC's income (passive 'foreign personal holding company' income, plus certain related-party sales and services) that 10%-U.S. shareholders must include currently, whether or not distributed; the predecessor regime to NCTI.
Subscription agreementSecurities & Offering
The investor's contract to purchase interests, bundled with the investor questionnaire establishing eligibility (accredited/QP status, ERISA, FATCA, AML/KYC); the closing mechanics of the fund.
Also: sub docs
Subscription line Subscription credit facilityEconomics & Fees
A fund credit line secured by the right to call investor capital, used to bridge capital calls and smooth funding. Because IRR clocks start at the (delayed) capital call, sustained use mechanically inflates reported IRR.
Why investors care: Investors and ILPA demand disclosure of levered vs. unlevered IRR, limits on duration (e.g., 180 days outstanding) and size, and watch the pref-accrual interaction: delayed calls also delay when the pref starts running.
Also: capital call facility, sub line
Successor fund restrictionGovernance & Terms
The GP may not raise a competing fund until the current fund is substantially invested (e.g., 70–75% of commitments invested, committed or reserved), protecting investors' claim on the team's attention.
SuspensionGovernance & Terms
A halt of the investment period (no new deals; often reduced fees) triggered by key-person events or cause determinations. Reversible by vote, unlike termination.
Tax distributionsTax
LPA provisions requiring (or permitting) the fund to distribute enough cash for partners to pay tax on allocated income, usually computed at an assumed rate; advances against future distributions.
Why investors care: Investors want them mandatory for the GP too. Confirm that GP tax distributions on carry aren't effectively an unsecured carry advance ahead of the clawback.
Temporary investments Short-term cash management (pending deployment or distribution)Economics & Fees
Short-term instruments in which the fund holds cash it is not yet using: money-market funds, Treasury bills, commercial paper and similar cash equivalents, held pending investment, pending distribution, or as reserves. The LPA's investment restrictions ordinarily except them from the fund's strategy limits.
Why investors care: Income on temporary investments generally does not run through the waterfall: it is typically distributed pro rata to the partners who funded the cash, without carried interest, and it is commonly excluded when measuring the preferred return. Hedging instruments are a separate concept: futures, swaps and options are commodity interests that can make the fund a commodity pool under CFTC rules.
Also: cash management, temporary investment income
Term / extensionsGovernance & Terms
The fund's life: typically 10 years plus two or three one-year extensions, each requiring GP discretion plus LPAC or investor consent (the negotiated point). Funds outliving extensions go into wind-down or seek continuation vehicles.
Why investors care: Investors resist GP-unilateral extensions: each extra year is another year of fees on a mature portfolio.
TopCo Club / JV acquisition entityStructures & Vehicles
The entity at the top of a deal where multiple vehicles come together to make one investment: the main fund alongside a co-investment fund, other sponsors or direct co-investors. Each participant holds its stake in the TopCo, and the deal's governance lives in a shareholders or JV agreement at this level: board composition, reserved matters and vetoes, transfer restrictions (ROFR/ROFO, tag and drag rights) and exit mechanics.
Why investors care: Co-investors negotiate closely at the TopCo: minority protections, exit alignment (drag thresholds, IPO cooperation), information rights and fee leakage. The fund's LPs care that the fund controls (or has negotiated protections in) the TopCo, since fund-level governance does not reach it automatically.
Also: club deal, consortium, JV entity
Transfer restrictionsGovernance & Terms
LP interests are transferable only with GP consent (typically 'not unreasonably withheld' is the negotiated ask), conditioned on securities-law, tax (publicly traded partnership, §1446(f)) and ERISA compliance.
Why investors care: Investors planning secondary-market flexibility negotiate consent standards and pre-approved transferee lists up front; GPs control the register for 100-holder, PTP and plan-asset reasons.
Treaty benefits / LOB Income tax treaties; Limitation on BenefitsTax
Bilateral treaties reduce U.S. withholding on dividends/interest and can shield business profits absent a permanent establishment, but only for residents satisfying the treaty's LOB article, which polices treaty-shopping through intermediate holding companies.
Why investors care: Interposing a Luxembourg or Irish holding company does not by itself secure treaty benefits: the structure must qualify for treaty access through substance and qualifying ownership, and anti-abuse rules (PPT/MLI) add a second screen.
TVPI Total Value to Paid-InMetrics & Reporting
(Distributions + remaining NAV) ÷ capital paid in. The fund-level multiple including unrealized value; only as good as the valuations behind the NAV.
UBIT Unrelated Business Income TaxTax
The tax actually imposed on UBTI, at regular corporate (or trust) rates. UBTI is the income; UBIT is the tax bill.
UBTI Unrelated Business Taxable Income (IRC §§511–514)Tax
Income a U.S. tax-exempt investor (pension, endowment, foundation, IRA) earns from an active trade or business unrelated to its exempt purpose, or from debt-financed investments, that is taxable even though the investor is otherwise exempt.
Why investors care: Tax-exempt investors avoid it: it converts tax-free returns into taxable ones and requires them to file Form 990-T. Many will not invest in a fund that generates UBTI, so funds interpose blockers or covenant to avoid it.
Also: unrelated business
USRPHC U.S. Real Property Holding Corporation (IRC §897(c)(2))Tax
A U.S. corporation 50% or more of whose asset value, on the §897(c)(2) base of USRPIs, non-U.S. real property and trade-or-business assets, is U.S. real property interests. A USRPHC's STOCK is itself a USRPI, so a non-U.S. person's sale of the stock is a FIRPTA disposition.
Why investors care: Why an ordinary C-corporation blocker often lacks a FIRPTA-free exit on real estate (a dedicated real-property blocker is typically a USRPHC); the common answer is a domestically-controlled REIT.
USTB U.S. trade or businessTax
The threshold concept for ECI: regular, continuous and considerable business activity in the U.S. Loan origination, development activity and operating businesses generally are a USTB; trading securities for one's own account generally is not (the §864(b)(2) trading safe harbors).
VCOC Venture Capital Operating Company (29 C.F.R. §2510.3-101(d))Regulatory
A plan-asset exception: an entity with 50%+ of assets in operating companies in which it has direct contractual management rights, obtained at the time of investment, with the first investment qualifying and an annual valuation-period test thereafter.
Why investors care: The reason funds insist on management-rights letters in deals even where the governance rights are not otherwise needed: each ERISA-sensitive vehicle must maintain its VCOC status with qualifying investments.
Vintage yearMetrics & Reporting
The year a fund begins investing (or holds first/final close; conventions vary). Performance is benchmarked within a vintage, since macro timing dominates absolute returns.
VolatilityMetrics & Reporting
The annualized standard deviation of periodic returns: a measure of how widely results scatter around their average, not the worst-to-best range for a year. As a general approximation, roughly two thirds of annual outcomes fall within one standard deviation of the expected return, and about ninety-five percent within two. A fund with a 9% expected return and 15% volatility would see most years fall between roughly -6% and +24%.
Why investors care: In Structura, volatility is an INPUT: the figure entered in the NAV Model Assumptions drives the simulated return paths, and the Sharpe and Sortino ratios are then computed from the simulated returns, never the reverse. To estimate it from a track record, take the standard deviation of monthly returns and multiply by the square root of twelve, or of quarterly returns and multiply by two; comparable strategies or an asset-class benchmark are the other common references. The worst-to-best question is answered separately, by the risk table's median worst and best calendar year rows and the maximum drawdown figures.
Also: standard deviation of returns
W-8 / W-9Tax
IRS certification forms collected in subscription documents: W-9 for U.S. persons; the W-8 family (W-8BEN, BEN-E, IMY, ECI, EXP) for non-U.S. persons, establishing withholding status, treaty claims and FATCA classification.
Waterfall Distribution waterfallEconomics & Fees
The ordered tiers through which distributions flow: return of capital, then preferred return, then GP catch-up, then the carry split (e.g., 80/20). The defining economic mechanic of a closed-end fund.
