问题如下：
4 Based on Exhibit 1 and the proposed asset allocation, the greatest risk associated with the ERIP is:
选项：
A. liability.
B. leverage.
C. liquidity.
解释：
C is correct.
With the introduction of the early retirement incentive plan (ERIP), the defined benefit pension plan will likely be called upon to make pension payments earlier than originally scheduled. As a result, the near term liquidity of the plan is the greatest risk arising from the addition of the alternative asset classes (e.g., private equities, hedge funds, and real estate). Investments in alternatives, such as private equities, can take upwards of five years to reach a full commitment and potentially another decade to unwind.
这个题为什么不是A呢？ 是说要在两年内从inv出来支付么？那还有两年呢？这个算liquidity么？
