问题如下：
PZ is the sponsor of a $1.25 billion
legacy DB plan, which is now frozen. The funded ratio is 0.8. The plan sponsor, receives three asset allocation approaches
recommendations:
•
a surplus optimization approach.
•
an integrated asset–liability approach.
•
a hedging/return-seeking portfolios approach.
When evaluate asset allocation choices, consider the plan
sponsor’s costs.
Determine which asset allocation approach would be most appropriate for the pension fund. Justify your response.
解释：
Surplus optimization approach is the most appropriate.
Surplus optimization does not require an overfunded status, while implementation of the basic two-portfolio approach depends on having an overfunded plan.
Integrating the liability portfolio with the asset portfolio, is the most comprehensive of the three approaches, but increased complexity.
如果surplus为负也可以optimize. 请问老师，题目信息中哪处是不支持integrated asset-liability approach？或者说这道题什么情况下不选surplus，而选integrated？
