A. GIPS exist as a best or maximum worldwide standard where local or country specific law for in vestment performance measurement does not exist.
B. GIPS require that managers rank order all fee - paying discretionary portfolios back at least five years or for as long as they have been in existence.
C. GIPS require that all fee - paying discretionary portfolios be included in composites defined according to investment objective or similar strategy and firms must show GIPS compliant history for a minimum of five years or since inception if a composite has existed less than five years.
参考答案：C
解析：
GIPS provides a minimum, not a maximum, standard for investment performance measurement and/or presentation. GIPS requires that all fee - paying discretionary portfolios be included in a composite, not rank ordered, to prevent firms from presenting the results of their best portfolios. GIPS is intended to foster the notion of self - regulation, not a world - wide regulatory body, to oversee investment performance and measurement.
