A large pension fund is restructuring its fixed-income portfolio as part of a liability-driven investment strategy. The fund has forecasted annual pension benefit payments of $5 million over the next five years, and then a larger payment of $30 million due in year six. The fund manager is considering a cash flow matching strategy and evaluating two bond portfolios:
- Portfolio X: A series of zero-coupon bonds maturing in five years with a face value of $5 million, and a single zero-coupon bond maturing in year six with a face value of $30 million.
- Portfolio Y: A mix of coupon-bearing bonds that offer cash flows of $1 million annually for the first five years and a single coupon-bearing bond that matures in year six, providing a face value of $30 million.
The manager seeks to determine which portfolio best aligns with the liability stream of pension payments to ensure liquidity and avoid reinvestment risk.
