Private Equity Waterfall Calculation
Calculate distribution waterfalls for private equity funds with hurdle rates, catch-up provisions, and carried interest allocations
Waterfall Distribution Results
Comprehensive Guide to Private Equity Waterfall Calculations
The private equity waterfall distribution model determines how profits are shared between limited partners (LPs) and general partners (GPs) in a fund. This complex but essential mechanism ensures that GPs are properly incentivized while LPs receive fair returns on their investments.
Key Components of Waterfall Distributions
- Hurdle Rate: The minimum annualized return (typically 6-10%) that LPs must receive before the GP participates in profit sharing. This is often calculated using IRR (Internal Rate of Return).
- Catch-up Provision: After the hurdle rate is met, the GP receives a disproportionate share of distributions until they reach their agreed carried interest percentage (usually 20%).
- Carried Interest: The GP’s share of profits (typically 20%) after the hurdle rate and catch-up provisions are satisfied.
- Management Fees: Annual fees (typically 1-2% of committed capital) paid to the GP for fund management, which reduce the available capital for investments.
- Distribution Types:
- European (Deal-by-Deal): Profits are distributed after each individual investment exit
- American (Fund-as-a-Whole): Profits are distributed only after all investments are realized and the hurdle rate is met for the entire fund
How Waterfall Calculations Work in Practice
Let’s examine a typical waterfall scenario with a $100 million fund:
| Component | European Waterfall | American Waterfall |
|---|---|---|
| Initial Capital | $100,000,000 | $100,000,000 |
| Management Fee (2% annually) | $2,000,000/year | $2,000,000/year |
| Hurdle Rate | 8% IRR | 8% IRR |
| Carried Interest | 20% | 20% |
| First Exit ($150M after 3 years) | LP gets 100% until hurdle met, then 80/20 split | No distribution until all exits complete |
| Final Fund Value ($300M after 5 years) | Multiple distributions over time | Single distribution calculation |
| GP Total Carried Interest | ~$30-40M (varies by deal timing) | $40M (20% of $200M profit) |
The choice between European and American waterfalls significantly impacts both LPs and GPs:
- European waterfalls provide earlier liquidity to LPs but may result in lower total carried interest for GPs if early deals perform exceptionally well.
- American waterfalls typically result in higher carried interest for GPs when the fund performs well overall, but delay distributions to LPs until all investments are realized.
Mathematical Foundation of Waterfall Calculations
The waterfall calculation follows this general sequence:
- Calculate Total Capital Called: Total committed capital minus any unused commitments
- Determine Management Fees: Typically 1-2% of committed capital annually
- Compute Net Invested Capital: Total capital called minus management fees
- Calculate Hurdle Rate Return: Net invested capital × (1 + hurdle rate)years
- Apply Catch-up Provision: If applicable, allocate profits to GP until carried interest percentage is reached
- Distribute Remaining Profits: Split between LP (typically 80%) and GP (typically 20%)
The formula for determining when the hurdle rate is met uses the Internal Rate of Return (IRR) calculation:
0 = -∑(Capital Calls) + ∑[Distributions / (1 + IRR)t]
Where t represents the time in years between the investment and each distribution.
Real-World Waterfall Distribution Example
Consider a $100 million private equity fund with these terms:
- 2% annual management fee on committed capital
- 8% hurdle rate (IRR)
- 20% carried interest
- 5-year investment period
- European (deal-by-deal) distribution waterfall
After 5 years, the fund exits all investments for $300 million. Here’s how the waterfall would work:
| Item | Calculation | Amount |
|---|---|---|
| Total Committed Capital | – | $100,000,000 |
| Management Fees (2% × 5 years) | $100M × 2% × 5 | $10,000,000 |
| Net Invested Capital | $100M – $10M | $90,000,000 |
| Hurdle Rate Return (8% IRR over 5 years) | $90M × (1.08)5 | $133,822,558 |
| Total Exit Value | – | $300,000,000 |
| Profit Above Hurdle | $300M – $133.8M | $166,177,442 |
| LP Distribution (80%) | $166.2M × 80% | $132,941,953 |
| GP Carried Interest (20%) | $166.2M × 20% | $33,235,488 |
| Total LP Distribution | $133.8M + $132.9M | $266,764,511 |
| Total GP Distribution | $10M (fees) + $33.2M | $43,235,488 |
This example demonstrates how the waterfall ensures LPs receive their hurdle rate return before the GP participates in profit sharing. The GP’s total compensation comes from both management fees and carried interest.
Tax Implications of Waterfall Distributions
Waterfall distributions have significant tax consequences for both LPs and GPs:
- For Limited Partners (LPs):
- Return of capital is not taxable
- Capital gains from profitable investments are typically taxed at long-term rates (15-20%) if held >1 year
- Ordinary income from management fee offsets may be taxed at higher rates
- For General Partners (GPs):
- Management fees are typically taxed as ordinary income (up to 37% federal rate)
- Carried interest is often taxed as long-term capital gains (20% federal rate under current law)
- The “three-year holding period” rule for carried interest (from 2017 Tax Cuts and Jobs Act) requires assets to be held for three years to qualify for long-term capital gains treatment
The tax treatment of carried interest has been a subject of political debate. The Inflation Reduction Act of 2022 maintained the three-year holding period requirement for carried interest to qualify for long-term capital gains treatment.
Common Waterfall Structures in Private Equity
While the basic waterfall structure is consistent, funds employ several variations:
- Standard Waterfall:
- 100% to LPs until hurdle rate is achieved
- Then 80/20 split between LPs and GP
- Modified European Waterfall:
- Combines elements of European and American waterfalls
- Allows for deal-by-deal distributions but with fund-level hurdle rate calculations
- Tiered Waterfall:
- Different carried interest percentages at different return thresholds
- Example: 10% carried interest up to 15% IRR, 20% above 15% IRR, 30% above 25% IRR
- First-Deal Priority:
- First profitable deal distributions go entirely to LPs until hurdle is met
- Subsequent deals follow standard waterfall
- GP Clawback Provisions:
- Requires GP to return excess distributions if final fund performance doesn’t meet hurdle rate
- Typically calculated at fund termination
Negotiating Waterfall Terms
Waterfall terms are a key negotiation point between LPs and GPs. Several factors influence the final structure:
- Fund Size and Strategy:
- Larger funds (>$1B) often command more favorable terms for GPs
- Venture capital funds typically have higher hurdle rates (10-12%) than buyout funds (6-8%)
- GP Track Record:
- Established firms with strong performance may negotiate lower hurdle rates or higher carried interest
- First-time funds often face stricter terms (higher hurdles, lower carried interest)
- Market Conditions:
- In competitive fundraising environments, LPs may demand more favorable terms
- During market downturns, GPs may need to offer more LP-friendly terms to attract capital
- LP Composition:
- Institutional investors (pension funds, endowments) often negotiate better terms than individual investors
- Sovereign wealth funds may demand unique structures or side letters
According to research from the Columbia Business School, the average hurdle rate for private equity funds has declined slightly over the past decade, from 8.5% in 2010 to 7.8% in 2022, while carried interest has remained stable at approximately 19-20%.
Waterfall Calculation Challenges
Several complex issues can arise in waterfall calculations:
- Timing of Distributions:
- European waterfalls require tracking IRR for each individual investment
- Partial exits complicate calculations (e.g., selling 30% of a portfolio company)
- Recycling of Capital:
- When proceeds from early exits are reinvested, determining the cost basis becomes complex
- Different accounting treatments can significantly impact IRR calculations
- Multiple Currency Funds:
- Exchange rate fluctuations affect both capital calls and distributions
- Hurdle rates may need to be calculated in both local and fund currencies
- Side Letters and Most-Favored-Nation Clauses:
- Some LPs negotiate custom waterfall terms via side letters
- MFN clauses may require extending favorable terms to all LPs
- Fee Offsets and Transaction Fees:
- Management fees may be offset by transaction/monitoring fees from portfolio companies
- These offsets can reduce the effective management fee percentage
The U.S. Securities and Exchange Commission has increasingly scrutinized private equity fee and expense allocations, including how waterfall calculations are presented to investors. In 2022, the SEC brought enforcement actions against several firms for misallocating expenses in ways that affected waterfall distributions.
Best Practices for Waterfall Implementation
To ensure fair and accurate waterfall calculations, private equity firms should:
- Document All Terms Clearly:
- Precisely define hurdle rate calculation methodology (IRR vs. multiple of invested capital)
- Specify whether the hurdle is calculated gross or net of fees
- Detail the treatment of recycled capital and partial exits
- Implement Robust Systems:
- Use specialized private equity accounting software (e.g., eFront, Investran, or Allvue)
- Maintain audit trails for all distribution calculations
- Implement controls to prevent manual override of waterfall terms
- Provide Transparent Reporting:
- Include waterfall calculations in quarterly investor reports
- Disclose both realized and unrealized performance
- Offer detailed breakdowns of how each distribution was calculated
- Conduct Regular Audits:
- Engage independent auditors to verify waterfall calculations annually
- Perform clawback analyses before final distributions
- Review side letter compliance with waterfall terms
- Educate Investors:
- Host annual meetings to explain waterfall mechanics
- Provide examples of how different exit scenarios would affect distributions
- Offer modeling tools (like this calculator) to help LPs understand potential outcomes
The Future of Waterfall Structures
Several trends are shaping the evolution of waterfall distributions:
- Performance-Based Fee Structures:
- More funds are tying management fees to performance
- “1 or 30” structures (1% management fee if performance is below hurdle, 30% carried interest if above)
- ESG-Linked Waterfalls:
- Some funds adjust carried interest based on ESG performance metrics
- Example: +2% carried interest if portfolio companies meet sustainability targets
- Co-Investment Waterfalls:
- Separate waterfall terms for co-investment vehicles
- Often feature lower hurdle rates and higher carried interest for GPs
- Technology-Driven Transparency:
- Blockchain-based systems for real-time waterfall tracking
- Investor portals with interactive waterfall modeling
- Regulatory Changes:
- Potential modifications to carried interest tax treatment
- Increased disclosure requirements for waterfall terms
A 2023 study by the Harvard Business School found that private equity funds with more transparent waterfall structures and performance-based fee arrangements tended to outperform their peers by 1.2-1.8% annually, suggesting that alignment of interests between LPs and GPs drives better investment decisions.
Common Waterfall Calculation Mistakes to Avoid
Even experienced private equity professionals can make errors in waterfall calculations:
- Incorrect IRR Calculations:
- Using simple annualized returns instead of true IRR
- Miscounting the timing of cash flows
- Double-Counting Management Fees:
- Including management fees in both the cost basis and as offset items
- Failing to account for fee offsets from portfolio company monitoring fees
- Mishandling Recycled Capital:
- Treating recycled proceeds as new capital calls
- Incorrectly calculating the cost basis for reinvested funds
- Ignoring Currency Effects:
- Calculating hurdle rates in fund currency without considering local currency returns
- Failing to account for FX gains/losses in distribution waterfalls
- Overlooking Clawback Obligations:
- Not tracking cumulative distributions against final fund performance
- Failing to escrow sufficient funds for potential clawbacks
- Misapplying Side Letter Terms:
- Applying standard waterfall terms to LPs with custom side letters
- Failing to extend MFN clause benefits to all eligible LPs
- Improper Handling of Partial Exits:
- Distributing 100% of partial exit proceeds to LPs without considering hurdle rate
- Not properly allocating the remaining cost basis after partial exits
To mitigate these risks, funds should implement automated waterfall calculation systems with built-in validation checks and engage specialized private equity accountants to review calculations quarterly.
Waterfall Calculations in Different Private Equity Strategies
Waterfall structures vary significantly across private equity strategies:
| Strategy | Typical Hurdle Rate | Typical Carried Interest | Distribution Type | Key Considerations |
|---|---|---|---|---|
| Leveraged Buyouts | 6-8% IRR | 20% | European or American | Debt financing affects IRR calculations; often use fund-as-a-whole waterfalls |
| Venture Capital | 10-12% IRR | 20-25% | Deal-by-deal | High failure rate of early-stage investments requires deal-by-deal distributions |
| Growth Equity | 8-10% IRR | 20% | Modified European | Hybrid approach with fund-level hurdle but deal-by-deal distributions |
| Distressed Debt | 10-15% IRR | 15-20% | American | Complex restructuring timelines favor fund-as-a-whole approach |
| Real Estate | 6-10% IRR | 10-20% | Deal-by-deal | Property-specific waterfalls with promote structures (e.g., 5% to GP after 8% IRR) |
| Infrastructure | 5-8% IRR | 15-20% | American | Long hold periods (10-15 years) favor fund-as-a-whole distributions |
The choice of waterfall structure should align with the fund’s investment strategy, hold period, and risk profile. Funds with longer investment horizons and lower liquidity (like infrastructure) typically benefit from American waterfalls, while strategies with more frequent realizations (like venture capital) often use European waterfalls.
Legal Considerations in Waterfall Structures
Waterfall provisions must comply with various legal and regulatory requirements:
- Limited Partnership Agreement (LPA):
- The LPA must clearly define all waterfall terms
- Any ambiguities are typically interpreted in favor of LPs
- Securities Laws:
- Waterfall terms must be disclosed in offering memoranda
- Material changes to waterfall structures may require LP consent
- Fiduciary Duty:
- GPs have a fiduciary duty to act in the best interests of LPs
- Waterfall calculations must be fair and consistent with LPA terms
- Tax Regulations:
- IRS rules govern the tax treatment of carried interest
- State and local taxes may affect net distributions to LPs
- International Considerations:
- Cross-border funds must comply with waterfall regulations in multiple jurisdictions
- Tax treaties may affect withholding on distributions
The Institutional Limited Partners Association (ILPA) provides comprehensive guidelines on waterfall structures and other private equity terms in their Private Equity Principles, which are widely adopted across the industry.

Case Study: Waterfall Calculation in Action
Let’s examine a real-world example (with anonymized details) of how a mid-market buyout fund applied its waterfall structure:
Fund Profile:
- $500 million fund size
- 8% hurdle rate (IRR)
- 20% carried interest
- 2% annual management fee
- American (fund-as-a-whole) waterfall
- 5-year investment period, 10-year fund life
Investment Performance:
- Called 90% of capital ($450 million) over 4 years
- Management fees totaled $36 million (2% × $500M × 4 years + reduced fees in years 5-10)
- Net invested capital: $414 million
- Realized exits totaled $1.2 billion over 8 years
Waterfall Calculation:
| Step | Calculation | Amount |
|---|---|---|
| 1. Calculate hurdle rate return | $414M × (1.08)8 | $710,450,112 |
| 2. Determine profit above hurdle | $1,200M – $710.5M | $489,549,888 |
| 3. Allocate profit per waterfall | $489.5M × 80% to LP, 20% to GP | LP: $391,639,910 GP: $97,909,978 |
| 4. Calculate total distributions | Hurdle return + LP profit share | LP: $1,102,090,022 GP: $133,909,978 |
| 5. Include management fees | Add $36M to GP total | GP Total: $169,909,978 |
In this case, the GP received:
- $36 million in management fees
- $97.9 million in carried interest
- Total compensation of $133.9 million (26.8% of total distributions)
The LPs received $1.1 billion, representing a 2.4x multiple on their invested capital and a 19.3% IRR over the 8-year period.
Emerging Trends in Waterfall Structures
Several innovative approaches to waterfall distributions are gaining traction:
- GP Commitment Waterfalls:
- GP’s carried interest is reduced if their personal commitment to the fund is not fully invested
- Encourages GPs to co-invest alongside LPs
- Time-Vested Carried Interest:
- Carried interest vests over time (e.g., 20% per year over 5 years)
- Prevents GPs from receiving full carried interest if they leave the firm early
- Performance Hurdles for Carried Interest:
- Different carried interest percentages at different return thresholds
- Example: 10% up to 15% IRR, 20% up to 25% IRR, 30% above 25% IRR
- LP Advisory Committee Approval:
- Major waterfall adjustments require LPAC approval
- Increases transparency and LP alignment
- ESG-Linked Waterfalls:
- Carried interest adjusted based on portfolio company ESG performance
- Example: +2% carried interest if portfolio meets sustainability targets
- Evergreen Fund Waterfalls:
- Continuous waterfall calculations for evergreen funds with no fixed term
- Complex tracking of vintage-year returns
- Tokenized Waterfalls:
- Blockchain-based distribution systems with smart contracts
- Automated, transparent waterfall calculations
These innovative structures aim to better align GP and LP interests, improve transparency, and adapt to changing investor demands for responsible investing and performance-based compensation.
Waterfall Calculations for Co-Investments
Co-investment vehicles often have different waterfall structures than the main fund:
- Typical Co-Investment Waterfall Terms:
- Lower or no hurdle rate (since co-investors bear more risk)
- Higher carried interest (25-30%)
- Deal-by-deal distributions
- No management fees (or reduced fees)
- Key Differences from Main Fund:
- Co-investors often get “first money out” before main fund waterfall applies
- Different realization timelines may affect IRR calculations
- Separate accounting and reporting requirements
- Allocation Challenges:
- Determining fair allocation between main fund and co-investment vehicles
- Handling cases where co-investors have different economics than main fund LPs
Co-investment waterfalls require careful structuring to ensure fairness between the main fund LPs and co-investors while maintaining proper incentives for the GP.
Waterfall Calculations in Secondary Transactions
Secondary market transactions (sales of LP interests) add complexity to waterfall calculations:
- Transfer of Waterfall Rights:
- New buyer inherits the seller’s position in the waterfall
- Must account for any prior distributions received by the seller
- Valuation Considerations:
- Secondary price reflects the remaining waterfall potential
- Buyer’s IRR will differ from original LP’s IRR
- Clawback Provisions:
- Seller may remain liable for clawback obligations
- Buyer typically assumes future clawback risk
- Stapled Secondaries:
- Combined sale of existing LP interest and commitment to new fund
- Requires harmonizing waterfall terms between old and new funds
Secondary transactions often require specialized waterfall modeling to determine fair pricing and to allocate future distributions between the selling and buying parties.
Waterfall Calculations for Evergreen Funds
Evergreen funds (funds with no fixed termination date) present unique waterfall challenges:
- Continuous Waterfall Calculations:
- Must track IRR from initial investment for each vintage year
- Requires complex accounting for ongoing capital calls and distributions
- Vintage-Year Tracking:
- Each investment cohort may have its own waterfall
- Later investors may have different hurdle rates or carried interest terms
- Liquidity Management:
- Regular liquidity events (e.g., annual tender offers) complicate waterfall tracking
- Must maintain reserves for potential clawbacks across multiple vintages
- Performance Reporting:
- Must report performance by vintage year and overall
- IRR calculations become more complex with ongoing capital flows
Evergreen funds typically require sophisticated software systems to manage the continuous waterfall calculations and provide transparent reporting to investors with different vintage years.
Waterfall Calculations in Fund-of-Funds Structures
Funds-of-funds (which invest in multiple private equity funds) have additional waterfall complexity:
- Layered Waterfall Structures:
- First waterfall at the underlying fund level
- Second waterfall at the fund-of-funds level
- Currency Hedging Considerations:
- Underlying funds may be in different currencies
- Must calculate hurdle rates in both local and fund currencies
- Timing Mismatches:
- Underlying funds may have different vintage years and realization timelines
- Must aggregate performance across funds with different lifecycles
- Fee Structures:
- “1 and 10” structure (1% management fee, 10% carried interest) is common
- Must account for both the fund-of-funds fees and underlying fund fees
Fund-of-funds managers must carefully model the combined effect of multiple waterfalls to ensure their own hurdle rates are realistic given the underlying fund structures.
Waterfall Calculations for Impact Investing Funds
Impact investing funds often incorporate non-financial metrics into their waterfall structures:
- Double Bottom Line Waterfalls:
- Financial hurdle rate (e.g., 6% IRR)
- Impact hurdle (e.g., 30% reduction in carbon emissions across portfolio)
- Impact-Linked Carried Interest:
- Base carried interest (e.g., 15%)
- Additional carried interest (e.g., +5%) if impact targets are met
- Tiered Impact Waterfalls:
- Different carried interest percentages based on impact performance tiers
- Example: 10% for financial hurdle, 15% for basic impact, 20% for stretch impact
- Impact First, Returns Second:
- Some funds prioritize impact over financial returns in waterfall calculations
- May have lower financial hurdles or cap GP carried interest
These structures require sophisticated impact measurement systems alongside traditional financial tracking to properly calculate distributions.
Waterfall Calculations in Venture Capital
Venture capital funds typically use deal-by-deal waterfalls due to the high failure rate of early-stage investments:
- Key Characteristics:
- Deal-by-deal distributions
- Higher hurdle rates (10-12% IRR)
- Often include “first deal priority” provisions
- Challenges:
- Tracking IRR for each individual investment
- Handling partial exits (e.g., secondary sales of portfolio company shares)
- Managing escrow accounts for potential clawbacks from successful deals
- Typical VC Waterfall Example:
- $100M fund, 2% management fee, 10% hurdle, 20% carry
- Invest $2M in Company A, which exits for $20M after 3 years
- IRR = (20/2)^(1/3) – 1 = 258% (far above 10% hurdle)
- LP gets $16M (80% of profit), GP gets $4M (20% of profit)
- If next 9 deals lose money, LP still keeps $16M from first deal
This deal-by-deal approach allows VCs to distribute profits from successful investments early, which helps with fundraising for subsequent funds even if other investments in the current fund haven’t realized yet.
Waterfall Calculations in Real Estate Private Equity
Real estate funds often use promote structures that differ from traditional private equity waterfalls:
- Typical Real Estate Waterfall:
- 8-10% preferred return (like a hurdle rate)
- Then 70/30 split (LP/GP) until LP achieves 12-15% IRR
- Then 50/50 split above high-water mark
- Key Differences from PE Waterfalls:
- Often calculated on a property-by-property basis
- May include development promotes for value-add strategies
- Frequently use “lookback” provisions to true up distributions
- Example Calculation:
- $50M property acquisition, $10M in improvements
- Sold for $90M after 5 years
- LP gets first $60M (100% until 8% preferred return)
- Next $15M split 70/30 ($10.5M LP, $4.5M GP)
- Final $15M split 50/50 ($7.5M LP, $7.5M GP)
- Total distributions: LP $78M, GP $12M
Real estate waterfalls often include additional complexity for development projects, where promotes may be paid at various stages (e.g., upon achieving development milestones).
Waterfall Calculations in Infrastructure Funds
Infrastructure funds, with their long hold periods and steady cash flows, use unique waterfall structures:
- Key Characteristics:
- Long hurdle periods (10-15 years)
- Often use cash-on-cash returns alongside IRR
- May include availability-based hurdles for operational assets
- Cash Flow Waterfalls:
- Regular distributions from operating assets
- Must track cumulative distributions against hurdle
- Often include reserve accounts for maintenance capex
- Example Structure:
- 6% cash-on-cash hurdle (annual distribution yield)
- Then 8% IRR hurdle over 15 years
- Then 80/20 split above hurdles
- GP may receive additional promote for exceeding availability targets
Infrastructure waterfalls must account for the unique cash flow patterns of long-lived assets, where steady distributions may begin early in the fund’s life but continue for decades.
Waterfall Calculations in Debt Funds
Private debt funds use waterfall structures that reflect their income-focused strategies:
- Typical Debt Fund Waterfall:
- Current pay (regular interest distributions) to LPs
- Hurdle rate based on cash yield (e.g., 7-9%)
- Carried interest on residual value (after principal repayment)
- Key Features:
- Priority of payments: interest → principal → carried interest
- Often include “catch-up” periods for non-performing loans
- May have different hurdles for senior and subordinated debt
- Example Calculation:
- $100M fund, 8% hurdle, 15% carried interest
- Loans generate $8M annual interest (8% yield)
- All interest paid to LPs (meets hurdle)
- At maturity, $110M principal returned to LPs
- Any residual value split 85/15 LP/GP
Debt fund waterfalls focus more on current yield and principal protection than the capital appreciation emphasis of traditional private equity waterfalls.
Waterfall Calculations in Royalty Funds
Royalty and revenue-sharing funds use unique waterfall structures tied to underlying cash flows:
- Typical Royalty Waterfall:
- LP receives 100% of royalties until hurdle is met
- Then split (e.g., 80/20) of excess royalties
- Often includes minimum royalty guarantees
- Key Challenges:
- Unpredictable royalty streams complicate hurdle calculations
- Must account for royalty stacking (multiple royalty interests)
- Different accounting for music, patent, and mineral royalties
- Example Structure:
- 10% hurdle rate on invested capital
- LP receives all royalties until hurdle is achieved
- Then 75/25 split of excess royalties
- GP may receive additional promote for exceeding revenue targets
Royalty fund waterfalls require sophisticated cash flow modeling to project when hurdle rates will be achieved given the uncertainty of royalty income.
Waterfall Calculations in Fund Restructurings
When private equity funds undergo restructurings (e.g., GP-led secondaries, fund recapitalizations), waterfall calculations become particularly complex:
- Key Issues in Restructurings:
- Determining the fair value of remaining assets
- Allocating existing waterfall positions to new vehicles
- Handling carried interest for transferred assets
- GP-Led Secondary Waterfalls:
- New waterfall for continuation vehicle
- Must account for prior distributions to rolling LPs
- Often includes “top-up” carried interest for GP
- Stapled Financing Waterfalls:
- Combines new capital with transferred assets
- Requires harmonizing old and new waterfall terms
- Often includes ratchet mechanisms based on future performance
- Zombie Fund Restructurings:
- May waive hurdle rates for remaining assets
- Often includes reduced carried interest for GP
- May create separate waterfalls for different asset buckets
Fund restructurings typically require specialized legal and accounting advice to ensure waterfall terms are properly transitioned and all parties are treated equitably.
Waterfall Calculations in Evergreen Funds
Evergreen funds (funds with no fixed termination date) present unique waterfall challenges:
- Continuous Waterfall Calculations:
- Must track IRR from initial investment for each vintage year
- Requires complex accounting for ongoing capital calls and distributions
- Vintage-Year Tracking:
- Each investment cohort may have its own waterfall
- Later investors may have different hurdle rates or carried interest terms
- Liquidity Management:
- Regular liquidity events (e.g., annual tender offers) complicate waterfall tracking
- Must maintain reserves for potential clawbacks across multiple vintages
- Performance Reporting:
- Must report performance by vintage year and overall
- IRR calculations become more complex with ongoing capital flows
Evergreen funds typically require sophisticated software systems to manage the continuous waterfall calculations and provide transparent reporting to investors with different vintage years.
Waterfall Calculations in Fund-of-Funds Structures
Funds-of-funds (which invest in multiple private equity funds) have additional waterfall complexity:
- Layered Waterfall Structures:
- First waterfall at the underlying fund level
- Second waterfall at the fund-of-funds level
- Currency Hedging Considerations:
- Underlying funds may be in different currencies
- Must calculate hurdle rates in both local and fund currencies
- Timing Mismatches:
- Underlying funds may have different vintage years and realization timelines
- Must aggregate performance across funds with different lifecycles
- Fee Structures:
- “1 and 10” structure (1% management fee, 10% carried interest) is common
- Must account for both the fund-of-funds fees and underlying fund fees
Fund-of-funds managers must carefully model the combined effect of multiple waterfalls to ensure their own hurdle rates are realistic given the underlying fund structures.
