b. Critique. The Coastal proposal produces a real, after-tax expected return of
approximately 5.18%, which exceeds the 3% level sought by Fairfax. The expected
return for this proposal can be calculated by first subtracting the tax-exempt yield from
the total current yield: 4.9% − 0.55% = 4.35%
Finally, the 4% inflation rate is subtracted to produce the expected real after-tax return:
This result can also be obtained by computing these returns for each of the individual
holdings, weighting each result by the portfolio percentage and then adding to derive a
total portfolio result.
From the data available, it is not possible to determine specifically the inherent
degree of portfolio volatility. Despite meeting the return criterion, the allocation is
neither realistic nor, in its detail, appropriate to Fairfax’s situation in the context of an
investment policy usefully applicable to her. The primary weaknesses are the
following:
• Allocation of Equity Assets. Exposure to equity assets will be necessary in order to
achieve the return requirements specified by Fairfax; however, greater diversification
of these assets among other equity classes is needed to produce a more efficient,
potentially less volatile portfolio that would meet both her risk tolerance parameters
and her return requirements. An allocation that focuses equity investments in U.S.

• Cash allocation. Within the proposed fixed-income component, the 15% allocation
to cash is excessive given the limited liquidity requirement and the low return for
this asset class.
• Corporate/Municipal Bond Allocation. The corporate bond allocation (10 percent) is
inappropriate given Fairfax’s tax situation and the superior after-tax yield on municipal
