A non-profit organization has an endowment of $13,000,000, which is invested as follows: 30% in safe money market fund yielding an annual, real rate of return of 4%; 40% in an indexed stock fund with an expected long-run, annual real rate of return averaging 12%; and 30% in an aggressive growth fund with an expected long-run, average, annual rate of return of 15%. Given this portfolio allocation, what is the organization's expected annual operating budget if the management philosophy is to maintain the principal in the endowment at $13,000,000 and use the rate of return accumulation to finance annual operations?
