The client is willing to take some credit risk in pursuit of modest capital gains, but he expects you to diversify as much as possible and track the Barclay's Aggregate Bond index fairly closely. His salary is generous, so tax-advantaged securities are preferred. International securities are allowed if the credit rating is investment grade.As time has passed since your initial economic forecast, the economy has started slowing down and you've become concerned about a significant decline in intermediate-term interest rates in the next few months.
