Disciplinary disclosures

Civil judicial as of Aug 06, 2024

Allegations: THE SPANISH NATIONAL SECURITIES MARKETS COMMISSION (THE "CNMV") DETERMINED THAT RENAISSANCE HAD ENTERED INTO TRADES ON BEHALF OF FUNDS THAT IT MANAGES IN VIOLATION OF A SPANISH SHORT SELLING BAN ON THE SECURITIES OF LIBERBANK IN 2017. RENAISSANCE REDUCED LONG POSITIONS IN LIBERBANK AFTER THE SHORT SELLING BAN HAD TAKEN EFFECT. RENAISSANCE APPEALED THIS DECISION, ON THE GROUNDS THAT THE CNMV HAD IMPROPERLY BROADENED THE SCOPE OF THE SPANISH REGULATION AND OF THE BAN BEYOND THEIR INTENT AND PLAIN LANGUAGE IN SANCTIONING RENAISSANCE GIVEN THAT RENAISSANCE DID NOT ENGAGE IN ANY SHORT SALE TRANSACTION. Status: Final Summary: THIS JUDGMENT AFFIRMED THE DECISION OF THE SPANISH NATIONAL SECURITIES MARKETS COMMISSION AS DESCRIBED ABOVE IN A REGULATORY ACTION DRP. SEE QUESTION 13 OF THE REGULATORY ACTION DRP THAT DESCRIBES SANCTIONS PROCEEDING NO. 8/2018.

Regulatory · Item 11.D(2) as of Aug 06, 2024

Allegations: THE SWEDISH FINANCIAL SUPERVISORY AUTHORITY ALLEGED THAT RENAISSANCE TECHNOLOGIES LLC ("RENAISSANCE") HAD NOT TIMELY FILED NOTIFICATIONS REGARDING NET SHORT POSITIONS HELD BY RENAISSANCE-MANAGED FUNDS IN A SWEDISH LISTED SECURITY. Status: Final Sanction Detail: THE SWEDISH FINANCIAL SUPERVISORY AUTHORITY IMPOSED A SEK 1,000,000 FINE, WHICH WAS PAID BY RENAISSANCE IN U.S. DOLLARS ON MAY 17, 2021. THE AMOUNT OF THE FINE IN ITEM 12(A) ABOVE (USD 120,457) IS STATED IN U.S. DOLLARS USING THE EXCHANGE RATE ON THE DATE OF PAYMENT. Summary: IN SEPTEMBER 2017, RENAISSANCE SELF-REPORTED TO THE SWEDISH FINANCIAL SUPERVISORY AUTHORITY THAT ON MULTIPLE OCCASIONS IN 2016 AND 2017, IT HAD FAILED TO TIMELY FILE NOTIFICATIONS WITH RESPECT TO NET SHORT POSITIONS HELD BY RENAISSANCE-MANAGED FUNDS IN A SPECIFIC SWEDISH LISTED SECURITY ("SHORT NOTIFICATIONS"). THE FAILURE WAS DUE TO A CODING ERROR RELATED TO AN AMBIGUITY AS TO WHETHER TRANSACTIONS IN THAT PARTICULAR SECURITY WERE EXEMPT FROM REPORTING FOLLOWING A CORPORATE TRANSACTION BY THE ISSUER. RENAISSANCE DETECTED THE ERROR IN CONNECTION WITH A ROUTINE REVIEW AND CORRECTED IT. ON APRIL 22, 2021, THE SWEDISH FINANCIAL SUPERVISORY AUTHORITY DETERMINED THAT RENAISSANCE HAD NOT TIMELY FILED THE SHORT NOTIFICATIONS AND IMPOSED A FINE OF SEK 1,000,000 (USD 120,457). RENAISSANCE PAID THE FINE ON MAY 17, 2021.

Regulatory · Item 11.D(2), 11.D(4) as of Aug 06, 2024

Allegations: THE SPANISH NATIONAL SECURITIES MARKETS COMMISSION DETERMINED THAT RENAISSANCE TECHNOLOGIES LLC ("RENAISSANCE") HAD ENTERED INTO TRADES ON BEHALF OF FUNDS THAT IT MANAGES IN VIOLATION OF A SPANISH SHORT SELLING BAN ON THE SECURITIES OF LIBERBANK, S.A. ("LIBERBANK") IN 2017. RENAISSANCE REDUCED LONG POSITIONS IN LIBERBANK AFTER THE SHORT SELLING BAN HAD TAKEN EFFECT. Status: Final Sanction Detail: RENAISSANCE PAID THE SPANISH NATIONAL SECURITIES MARKETS COMMISSION A FINE EQUAL TO 150,000 EUROS ON JUNE 26, 2019. (THE MONETARY FINE IN 12(A) WAS CONVERTED INTO U.S. DOLLARS USING THE EXCHANGE RATE ON THE DATE OF PAYMENT.) Summary: THE SPANISH NATIONAL SECURITIES MARKETS COMMISSION (THE "CNMV") DETERMINED THAT IN 2017, RENAISSANCE ON BEHALF OF ITS FUNDS TRADED IN VIOLATION OF A SPANISH SHORT SELLING BAN ON THE SECURITIES OF LIBERBANK, S.A. ("LIBERBANK"). ALTHOUGH RENAISSANCE HAD NOT ENGAGED IN ANY SHORT SALES OF LIBERBANK, THE CNMV DETERMINED THAT RENAISSANCE'S REDUCTION OF LONG POSITIONS IN LIBERBANK VIOLATED THE SHORT SALE BAN BECAUSE IT RESULTED IN AN INCREASE IN THE FUNDS' NET SHORT POSITION IN LIBERBANK. RENAISSANCE'S APPEAL OF THE CNMV'S DETERMINATION TO THE SPANISH MINISTRY OF ECONOMY AND ENTERPRISE WAS REJECTED ON APRIL 1, 2019. RENAISSANCE PAID THE CNMV A FINE EQUAL TO 150,000 EUROS ON JUNE 26, 2019. (THE MONETARY FINE IN 12(A) WAS CONVERTED INTO U.S. DOLLARS USING THE EXCHANGE RATE ON THE DATE OF PAYMENT.) RENAISSANCE'S APPEALS TO THE SPANISH NATIONAL HIGH COURT AND THE SPANISH SUPREME COURT WERE REJECTED ON JUNE 18, 2020, AND JULY 7, 2021, RESPECTIVELY.
