Endowments Foundations

Section: Endowments and Foundations Estimated study time: 45 minutes Content: Endowments and foundations are institutional investors with perpetual or very long time horizons, making them distinct from pension funds (liability-driven) and individual investors (finite life). The primary investment objective for both is to maintain real spending power over time — distributing a sustainable annual amount while preserving the purchasing power of the endowment corpus against inflation. The spending rule determines the annual distribution from the endowment. The most common approach is a percentage-of-assets rule — distributing a fixed percentage (typically 4-5%) of a trailing average of portfolio value. Using a multi-year trailing average (often 3-year or 5-year) smooths spending distributions and reduces the impact of market volatility on the institution's budget. Private foundations in the US are legally required to distribute at least 5% of assets annually to qualify for tax-exempt status. University endowments have no fixed minimum but typically target distributions sufficient to fund a meaningful portion of operating expenses. The required return for an endowment is: spending rate + inflation + management fees. If an endowment distributes 5% annually, targets 2.5% inflation protection, and pays 0.5% in fees, it must earn approximately 8% nominal to maintain real purchasing power. This requirement, combined with the long time horizon and lack of short-term liquidity needs, is why endowments can and typically do invest heavily in illiquid assets — private equity, private real estate, venture capital, natural resources, and hedge funds. The Yale Endowment Model (or "endowment model") is the influential investment approach pioneered by David Swensen at Yale. Key characteristics: heavy allocation to alternative investments (often 50-70% of the portfolio in private equity, venture capital, real assets, and hedge…
