问题如下：
Deveraux and Foster review the total expected 12-month return (assuming no reinvestment income) for the global bond portfolio. Selected financial data are presented in Exhibit 2.
Based on Exhibit 2, the total expected return of the fund’s global bond portfolio is closest to:
选项：
A.0.90%.
2.20%.
3.76%.
解释：
B is correct.
The total expected return is calculated as:
Total expected return = Rolling yield + E(Change in price based on investor’s yield and yield spread view) – E(Credit losses) + E(Currency gains or losses)
Rolling yield = Yield income + Rolldown return
老师，这里第二年的price是98.62，与current year比，是上升了，那yield不是应该下降吗？所以这里的0.15%应该是用-0.15%代入计算吗？
-5.19 * (-0.15%) + 1/2 * 22 * (−0.15%)2
