A disadvantage of Strategy 1 is that:
选项：
A. price risk still exists.
B. interest rate volatility
introduces risk to effective matching.
C. there may not be enough bonds available to match all
liabilities.
解释：
C is correct.
It may be impossible to acquire zero-coupon bonds to precisely match liabilities because the city’s liabilities have varying maturities and amounts. In many financial markets, zero-coupon bonds are unavailable.
