GIPS Objectives (from Kaplan)
• Establish global, industry-wide best practices for the calculation and presentation of investment performance, so that performance presentations for GIPS-compliant firms can be compared regardless of their country location.
• Facilitate the accurate and unambiguous presentation of investment performance results to current and prospective clients.
• Facilitate a comparison of the historical performance of investment management firms so that clients can make educated decisions when hiring new managers.
• Encourage full disclosure and fair global competition without barriers to entry.
