As of December 31, 2013, MacArthur's assets totaled $6.3 billion. The Foundation's investment portfolio had a return of 10.77 percent in 2013 net of investment management costs.
The Foundation invests for the long term with the objective of earning a real rate of return, net of expenses, sufficient to fund its charitable giving and operations. The underlying principles of MacArthur's investment approach may be summarized as follows:
- The Foundation maintains a broadly diversified portfolio with allocation to a variety of asset classes, both public and private.
- The broad diversification, combined with rigorous analytical research, is intended to enable the Foundation to manage risk.
- The Foundation seeks to achieve strong net returns over time at a cost comparable to other institutions with similar asset allocations.
