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，关于Credit losses，我看有些题目的题目给的是正数，答案是减去。有的时候给的是负数，也是减去= =
有木有统一的规范啊？
