United States Investment Performance Committee

The United States Investment Performance Committee (USIPC) serves as the official local sponsoring organization (sponsor) for the Global Investment Performance Standards (GIPS®) in the United States. The purpose of the USIPC is to promote the adoption and implementation of the GIPS standards throughout the United States as the common method for calculating and presenting investment performance.

In collaboration with CFA Institute, we:

  • Advise on goals, policies, strategies, industry trends, and local market opportunities related to the GIPS standards;
  • Engage stakeholders and drive promotion and adoption of the GIPS standards and global industry standards in the United States market; and
  • Engage with regulators.

US country-specific guidance for calculating after-tax performance is now separate from the GIPS standards. Learn more about after-tax performance calculation and presentation in the United States.

Committee members serve a one-year term, renewable for three consecutive years.
