## When to Activate

- User is structuring a new GP/LP joint venture and needs a term sheet with waterfall economics
- User has an existing JV structure and needs to calculate distributions under specific scenarios
- User needs to explain a waterfall structure to an LP investor in plain language
- User mentions "promote," "waterfall," "preferred return," "GP/LP split," or "carry"

## Process

### Mode A: Structure from Scratch

**Step 1: Transaction Overview Table** -- property, price, sources/uses, timeline.

**Step 2: Capital Structure** -- contributions by party, capital call procedures, penalties for failure to fund, operating/capital reserves.

**Step 3: Equity Waterfall** -- tier-by-tier structure:
- Tier 1: Preferred return (X% annual to LP on unreturned capital, cumulative, compounding)
- Tier 2: Return of capital (pro-rata or LP-first)
- Tier 3: Catch-up (if applicable -- GP receives X% until GP has X% of all profits)
- Tier 4+: Profit splits at each IRR hurdle

**Step 4: Distribution Priority Flowchart** -- ASCII waterfall flow showing money movement through tiers.

**Step 5: Three Exit Scenarios** (downside/base/upside) -- full tier-by-tier dollar breakdowns per partner.

**Step 6: Promote Sensitivity Table** -- GP promote dollars and percentage at 6%, 8%, 10%, 12%, 15%, 18%, 20% IRR levels. This is the key enhancement: shows how GP economics scale with performance.

**Step 7: Governance Decision Matrix**:
- Tier 1 (GP sole authority): day-to-day operations, leasing under X SF
- Tier 2 (GP with LP notification): capex $X-Y, leases over X SF
- Tier 3 (LP approval required): sale, refinancing, capital calls over $X

**Step 8: Key Business Terms** -- hold period, refinancing, buy-sell, ROFR/ROFO, leasing, capex.

**Step 9: Exit & Liquidity** -- drag-along, tag-along, GP removal, forced sale, distribution timing.

**Step 10: Protective Provisions** -- LP veto rights, conflicts, non-compete, bankruptcy triggers.

**Step 11: Alignment Analysis** -- LP downside protection, GP upside incentive, fairness assessment, market comparison.

### Mode B: Calculate Distributions

Accept existing waterfall terms and run the calculation engine:

**Step 1: Operating Cash Flow Distribution** -- year-by-year, per partner, through each tier.

**Step 2: Three Exit Scenario Distributions** -- tier-by-tier dollar breakdown at downside, base, upside return levels.

**Step 3: Promote Visualization** -- GP share of profits at each LP IRR achieved.

**Step 4: Promote Sensitivity Table** -- GP promote at 6+ IRR levels.

**Step 5: Clawback Analysis** -- scenarios where GP must return distributions if final IRR falls below pref.

**Step 6: GP Total Compensation** -- promote + all fees combined ("all-in GP take").

**Step 7: LP Return Summary** -- IRR, equity multiple, total profit per scenario.

### Mode C: Explain Waterfall to LP

Reformat using educational structure:

**Step 1: Introduction** -- plain-language "What is a distribution waterfall?" No jargon or every term defined.

**Step 2: Tier-by-Tier Breakdown** -- "Who gets paid" / "What it means" / "GP share" format.

**Step 3: Worked Numerical Example** -- specific dollar amount (from lp_investment_amount) walking through every tier.

**Step 4: Your Final Returns** -- total received, profit, IRR, equity multiple.

**Step 5: Why This Benefits You** -- downside protection, aligned incentives, fair performance fee.

**Step 6: Comparison to Alternatives** -- vs. flat split or simpler structures.

**Step 7: Visual Flow Diagram** -- ASCII waterfall diagram.

## Output Format

Mode-dependent (see Process above). Mode A produces a term sheet document. Mode B produces calculation tables. Mode C produces plain-language narrative with worked examples.

## Red Flags & Failure Modes

- **Clawback omission**: If GP receives interim distributions and final IRR falls below pref, GP should return excess. Always address.
- **Fee stacking**: GP acquisition fee + asset management fee + disposition fee + promote can stack to 30%+ of profits. Always show "all-in GP take."
- **Insufficient GP co-invest**: LP alignment concern if GP contributes < 5-10% of equity. Always note co-invest percentage and alignment signal.
- **Missing governance thresholds**: A term sheet without specific dollar thresholds for approval tiers is unenforceable.
- **Market benchmarks**: Standard institutional: 8-10% pref, 20-30% promote above 8-10% hurdle. Flag significant deviations.

## Refusal Behavior

A waterfall term sheet / distribution schedule is a decision-grade artifact (it governs real GP/LP economics and goes to investors and counsel). It fails closed (refuses to emit a final-marked term sheet or distribution table) when:

- **Any unresolved `$X` / placeholder / TBD token remains in a load-bearing cell of the final output.** A `$X` used illustratively in the Input Schema (e.g. "capex over $X") is template notation, not output — but a final-marked term sheet or distribution table must not contain an unresolved `$X` or placeholder: every hurdle, split, equity figure, fee, and governance threshold must resolve to a concrete `production`/`overlay`/`decision-grade` value (per `docs/DATA_GRADES.md` §3) or the document refuses. A term sheet with `$X` approval thresholds is unenforceable and must not be finalized.
- **Required structural inputs are missing** (equity split, pref, promote tiers, hurdles). With fewer than the required fields present, produce a labeled `illustrative` structure, not an executable term sheet.
- **A figure cannot be tied to the deal economics** (hurdles must trace to the underwriting model's projected IRR/multiple) — flag the missing linkage rather than fabricate a hurdle.
- **The user requests a definitive legal/tax characterization** of the structure — defer to qualified counsel; this skill structures economics, it does not opine on enforceability or tax treatment.

See the data-grade ladder in `docs/DATA_GRADES.md` for the `confirmed | estimated | illustrative` definitions and which grades may back a final-marked output.

## Confidence and Provenance

- Default output fidelity is **estimated**: the waterfall is structured from the supplied deal parameters and market benchmarks, not an executed agreement.
- Label every output cell with a confidence grade -- `confirmed` (operator/agreement-sourced), `estimated` (derived/benchmarked here), or `illustrative` (sample/demo) -- and a source-class tag: `[operator]` deal-supplied, `[derived]` computed here, `[benchmark]` market standard, `[overlay]` fund-template assumption, `[placeholder]` sample.
- Worked distribution examples state whether each input is `confirmed` or `estimated`, so investors and counsel see which terms are settled versus illustrative before the structure is papered.

## Known Limitations

- **Economics, not enforceability.** This skill structures and computes distribution economics; it does not opine on legal enforceability, securities treatment, or tax characterization. Those require qualified counsel and tax review — the `investment_committee_approval_required` gate is the floor, not the ceiling.
- **Two-tier promote with a single catch-up.** The calculator models a preferred return, multi-tier IRR hurdles, and a single catch-up. Exotic structures (multiple catch-ups, clawbacks, GP loans, side-letter waterfalls, fee crossovers) are not modeled and must be papered separately.
- **Hurdles are only as good as the underwriting they trace to.** Tier hurdles are validated against the upstream `acquisition-underwriting-engine` projected IRR/multiple; an unresolved or stale underwriting model propagates into the waterfall and is surfaced, not silently absorbed.

## Chain Notes

- **Upstream**: `deal-quick-screen` (screened deal provides asset parameters).
- **Upstream**: `acquisition-underwriting-engine` (projected IRR/multiple defines waterfall hurdles).
- **Downstream**: `dd-command-center` (JV structure informs DD scope and LP approval gates).
- **Downstream**: `1031-exchange-executor` (exit waterfall interacts with 1031 proceeds).
- **Lateral**: Mode C output feeds directly into LP pitch materials.

## Computational Tools

This skill can use the following scripts for precise calculations:

- `scripts/calculators/waterfall_calculator.py` -- GP/LP distribution waterfall with preferred return, multi-tier promote, catch-up, and IRR calculation
  ```bash
  python3 scripts/calculators/waterfall_calculator.py --json '{"lp_equity": 9000000, "gp_equity": 1000000, "preferred_return": 0.08, "tiers": [{"hurdle_irr": 0.08, "gp_split": 0.20, "lp_split": 0.80}, {"hurdle_irr": 0.12, "gp_split": 0.30, "lp_split": 0.70}], "cashflows_by_period": [-10000000, 800000, 850000, 900000, 950000, 15000000], "catch_up_pct": 0.50}'
