May fit better for

• retail users seeking direct public access;
• users who treat the 13F as total economic exposure;

Risk-management language is not a guarantee

JANA states that it attempts to mitigate drawdown risk through due diligence, engagement, position limits and minimal-to-no leverage in the activist portfolio.

Current private funds remain separate vehicles

Current Form D/adviser records include:

• JANA Strategic Investments Benchmark Fund total raised: $761M
• JANA Strategic Investments Benchmark Offshore total raised: $99.6M

These are offering/fund metrics, not regulatory AUM.

Current adviser data also reports private-fund gross assets of roughly $2.3B.

• Private fund gross assets equal regulatory AUM: No

Assessment

JANA's Q2 13F is close to regulatory AUM because the strategy is concentrated public equity, but the two values remain legally and economically distinct. The review should emphasize constructive activism and concentration rather than treat the filing as a complete fund statement.
