Strategic Asset Allocation and Opportunistic Rebalancing for Foundations and Nonprofits

A goal of foundations in general is to achieve a level of return that is adequate to further their missions at an acceptable risk level; in other words, they do not wish to take on more risk than is necessary to accomplish the goal.  During bear markets, foundations are typically concerned about rapid and severe reductions in asset values.  Alternatively, during bull markets foundations may take on more risk than they need to achieve their long-term goals.  Over the long term, however, we believe that it is important to have a disciplined strategy and not overreact to short-term trends.

Revisiting Your Investment and Distribution Goals

Benjamin Franklin once said that nothing in this world is certain, except death and taxes.  Endowments suspend these certainties as they are generally exempt from taxes and live on indefinitely.  Endowment spending policies specify the balancing between appropriately funding today’s beneficiaries and protecting endowment assets for tomorrow’s beneficiaries.  Since fiduciaries maintain a substantial portfolio to fund the needs of both future and current generations, it is important to establish a portfolio allocation and payout policy that properly balances these competing demands.
