## What it does

The skill covers what the CFA Institute Global Investment Performance Standards require from firms that claim compliance. It handles composite construction, time-weighted return calculation, presentation, error correction policies, pooled fund reports and verification. Your agent reaches for it when you ask about composite membership rules, returns of terminated portfolios, or gross versus net of fees.

What sits inside is reference material, not code: the definition of the firm and of a composite, inclusion and exclusion rules, large cash flow policy, disclosure requirements. GIPS Reports and pooled fund reports get their own sections, as do advertising guidelines and wrap fee or SMA program performance. The skill works from the 2020 edition of the standard, effective January 1, 2020, which replaced the 2010 edition.

One caveat matters here. GIPS is a voluntary standard, not law, and no regulator mandates it. Firms self-declare compliance, and independent verification is what tests the claim. The skill states its regulatory status is current as of June 2026 and advises checking effective dates, dollar thresholds and pending rulemakings against current SEC, FINRA, FinCEN and CFA Institute sources before advising. For marketing materials under SEC Marketing Rule and FINRA 2210, use `advertising-compliance` instead.

## When to use it
- build a composite and decide which portfolios belong in it
- calculate a time-weighted return around external cash flows
- prepare a GIPS Report and a pooled fund report
- write an error correction policy for performance presentations
- check wrap fee or SMA program performance against GIPS

## Example prompts
- Check whether this portfolio can go into the composite under GIPS
- How do I calculate returns for a terminated portfolio?
- What has to be in the GIPS Report for our composite?

description: "Ensure firms claiming GIPS compliance under the CFA Institute Global Investment Performance Standards satisfy requirements for composite construction, performance calculation, presentation, and verification. Use when the user asks about building composites, time-weighted return calculation under GIPS, GIPS Reports and pooled fund reports, error correction policies, wrap fee or SMA program performance under GIPS, GIPS verification, or GIPS advertising guidelines. Also trigger when users mention 'claiming GIPS compliance', 'composite membership rules', 'terminated portfolio returns', 'gross vs net of fees under GIPS', or 'GIPS verification findings'.

# GIPS Compliance — Global Investment Performance Standards

Regulatory status current as of June 2026 — verify effective dates, dollar thresholds, and pending rulemakings against current SEC/FINRA/FinCEN and CFA Institute sources before advising.

## Core Concepts

### GIPS Overview and Applicability
The Global Investment Performance Standards are voluntary ethical standards maintained by the CFA Institute for calculating and presenting investment performance. GIPS are not law — no regulator mandates compliance — but they are widely adopted by investment managers seeking institutional mandates, as many institutional investors, consultants, and plan sponsors require or strongly prefer GIPS-compliant track records.

GIPS applies to "firms," defined as an investment firm, subsidiary, or division held out to clients or prospective clients as a distinct business entity. The definition of the firm is foundational: a firm must define itself consistently and cannot change its definition to manipulate compliance. A firm claiming GIPS compliance must do so on a firm-wide basis. A firm cannot claim compliance for select composites or strategies while excluding others — compliance is all or nothing.
