解释：
Whether or not balance sheet risks should be hedged with forward contracts is debatable. (Some argue that reducing the volatility of earnings is desirable; others argue that non-cash-flow risks should not be hedged.) If they are, it only makes sense to hedge the risk at one future time. Otherwise there is over-hedging. This is a key difference between transaction and translation risk.
