Capital calls from drawdown funds arrive at uncertain times and in uncertain amounts. Distributions can stall just when markets are stressed, and if the assets you planned to sell are falling too, you face forced sales at trough prices.
When a pension commits $100 million to a buyout fund, capital does not leave immediately. The general partner (GP) calls capital as deals appear, typically over three to seven years depending on the strategy, then distributes during the harvest period. Net cash flow follows a J-curve: negative for years, then strongly positive. The limited partner (LP) must keep enough liquidity to meet calls without forced selling.
Drawdown vehicles complicate asset allocation because the amount you commit is not the amount you end up holding. Four questions follow:
- Sizing: how large a commitment do you need to reach the allocation target?
- Deployment: when will new commitments actually be called and invested?
- Uncalled capital: where do you hold commitments while they wait to be called?
Common mistakes
- Treating secondary sales as all-or-nothing. A sale releases cash and transfers unfunded commitments, but at a stressed discount it realizes proceeds below reported NAV. Reported NAV may differ from fair value, so judge the sale's economic cost from expected net cash flows and your own circumstances.
- Assuming CPPI always protects the floor. Discrete rebalancing still holds the floor as long as each equity decline between rebalancings stays within what the cushion can absorb, which is exactly 1/m when the floor is constant and the riskless return is zero, and approximately 1/m when the floor and cash position change.
- Forgetting the foregone loss carryforward when switching managers. A fund below its high-water mark earns its recovery fee-free, while a new manager's gains are net of fees from the start. Treating the switch as costless ignores the carryforward benefit you surrender.
Bottom line
- Drawdown funds call capital over three to seven years, so commitments, NAV, and targets diverge; the overcommitment ratio (commitments over resources) has been observed at 125% to 140%, but the optimum minimizes idle-capital plus adverse-event costs.
- Funding risk is the inability to meet calls; stress-test calls, distributions, and spending needs, since default brings penalties, possible loss of paid-in capital, and lost GP access.
- The deterministic TA model uses six inputs (life L, bow B, rate of contribution (RC), growth G, capital commitment (CC), and yield Y) and three equations to solve for the total and new commitments that hit a target NAV, but...
- Unfunded commitments can sit in cash, public markets, or replication strategies, or a blend; liquid alternatives come in four types, exceeded $500 billion by 2025, and on average trail matched LP funds.
Exam shortcut
DECISION: Expect trends and want rising risk with wealth → buy-and-hold or CPPI. Expect range-bound markets with constant risk appetite → constant-mix. Floor needed and gap moves possible → traded-option OBPI, if premiums are affordable. Illiquid sleeve off target → compare a proxy overlay, commitment pacing, and a secondary sale on proxy fit, costs, and price.
