2. Tidewater’s performance presentation most likely fails to comply with the GIPS standards because it does not disclose the:
选项：
A. custom benchmark weights and
components.
B. presence, use, and extent of leverage
or derivatives.
C. date and reasons for the change in the
composite name.
解释：
GIPS Provision I.4.A.31 states, "If a custom benchmark or combination of multiple benchmarks is used, the firm must disclose the benchmark components, weights and re-balancing process." Tidewater discloses the frequency of custom benchmark rebalancing but does not describe the custom benchmark weights and components. B is not the best answer because the Standards require disclosure of the presence, use, and extent of leverage or derivatives only if the use of leverage or derivatives is material. C is incorrect because the Standards require only that firms disclose any changes to the name of a composite. Firms are not required to disclose the date and reasons for the composite name change. (See Section 3.11 of the reading.)
B不对是因为原文题干没有提到使用了衍生品吧，所以不用解释相关信息。
