How do foundation spending rules work and how do they differ from endowments?

US private foundations (501(c)(3) non-operating foundations) must distribute at least **5% of the average fair market value** of net investment assets annually, or face a 30% excise tax on the shortfall under IRC §4942.

This creates two important contrasts with endowments:

1. **Floor, not ceiling**: Foundations must spend ≥5%. Endowments choose a policy rate (often 4.5%).
2. **Regulatory teeth**: Foundations face tax penalties; endowments face only internal policy breaches.
3. **Purpose**: Foundations fund grants to external charities (mission-driven). Endowments fund their own operations.

**Investment policy implications**:

- Target real return = 5% payout + inflation + investment fees + administrative costs ≈ 7.5-8.5% nominal to preserve purchasing power.
- Liquidity: need 5% cash outflow plus grant scheduling. A foundation run by trustee Ezra Lindqvist structures 7-8% of liquid assets as a 1-year spending reserve.
- Risk tolerance: moderate-to-high; perpetual horizon but 5% outflow raises sequence-of-returns sensitivity.
- Multi-year smoothing: many foundations use a 3-year rolling average FMV to dampen spending volatility — legal and permitted under §4942.

Types:

- **Private non-operating foundation**: 5% rule applies (grantmaking).
- **Private operating foundation**: different rules (85% of income or adjusted rule).
- **Community foundation (public charity)**: no 5% rule; policy-driven.

IPS documentation must address how the 5% is measured (straight FMV or averaged), how qualifying distributions are counted (including direct program expenses), and how carry-forwards/carry-backs of excess distributions work.

Compared to endowments, foundations typically hold slightly more liquidity because the distribution requirement is legally binding and audited by the IRS on Form 990-PF annually.
