解释：
Exhibit 4 indicates that exposure to free-standing credit derivatives dramatically declined from a peak during the global financial crisis in 2008. If a derivatives contract is classified as freestanding, changes in its fair value are reported as income or expense in the income statement at each reporting period. The immediate recognition of a gain or loss in earnings, instead of reporting it in other comprehensive income, can lead to unexpected volatility of earnings and missed earnings targets. As a result, earnings volatility from the use of credit derivatives most likely decreased.
