A. Calculate the amount in USD required to rebalance the portfolio’s money duration.
Money Duration = Mod Duration × Market Value × 0.01
Bond 1 = 12.15 × $1,250,000 × 0.01 = $151,875
Bond 2 = 10.67 × $2,450,000 × 0.01 = $261,415
Bond 3 = 9.40 × $1,545,000 × 0.01 = $145,230
Bond 4 = 4.57 × $4,180,000 × 0.01 = $191,026
Portfolio’s money duration = $749,546
Rebalancing ratio = Desired money duration / Current money duration
Rebalancing ratio = $800,000 / $749,546 = 1.067313
Cash requirement = (Rebalancing ratio – 1) × Market value of portfolio
Cash requirement = 0.067313 × $9,425,000 = $634,425

B. Calculate the total expected return of the UK portfolio in USD.
E(R) = coupon income +/– rolldown return +/– price change due to investor’s benchmark yield view +/– price change due to investor’s view of credit spread +/– currency gains/losses
Coupon income = 6.20 / 92.28 = 6.72%
Rolldown return = 92.68 / 92.28 – 1 = 0.43%
Price change due to investor’s benchmark yield view = (–MD × ΔYield) + [½ × Convexity × (ΔYield)^2]
= (–7.3 × 0.28% + ½ × 32.5 × (0.28%)^2) = –2.03%
Credit losses = –0.05%
Currency gains = 0.16%
Expected total return = 6.72% + 0.43% – 2.03% – 0.05% + 0.16% = 5.23%

C. Contrast the treatment of fixed income securities in taxable and tax-deferred accounts.
The two primary sources of investment income that affect taxes for fixed income securities are coupon payments (interest income) and capital gains or losses. Taxes are payable only on capital gains and interest income that have actually been received.
Coupon payments (interest income) are typically taxed at the investor’s ordinary income tax rate, which is usually higher than the capital gains tax rate.
In taxable accounts, taxes are paid on an annual basis, whereas, in tax-deferred accounts, taxes are deferred until fund withdrawal from the accounts.
Tax-deferred accounts allow returns to accrue on a pretax basis until withdrawn, which can provide substantial compounding benefits

同学,下午好。
假设当前的money duration=10,我的目标money duration=12,那么我就需要重新调整久期,rebalance ratio=12/10=1.2。我在当前的资产基础上,还要再多配置20%。
