Fine Amount: $7,500,000
Primary Violation: Natural gas market manipulation
Relevant Period: February-April 2006
Overview
The Federal Energy Regulatory Commission (FERC) approved a $7.5 million civil penalty settlement with Amaranth Advisors L.L.C., Amaranth LLC, Amaranth Management Limited Partnership, Amaranth International Limited, Amaranth Partners LLC, Amaranth Capital Partners LLC, Amaranth Group Inc., Amaranth Advisors (Calgary) ULC, and Matthew Donohoe for alleged violations of FERC's anti-manipulation rule under section 1c.1 of its regulations, stemming from trading activities in the New York Mercantile Exchange (NYMEX) Natural Gas Futures Contract during 2006 that raised concerns about impacts on physical natural gas prices.
The case originated from a FERC investigation into trading activities by the Settling Respondents in the NYMEX Natural Gas Futures Contract (NG Futures Contract) during early 2006.
FERC issued a Show Cause Order on July 26, 2007, alleging that the respondents manipulated settlement prices through large sales during settlement periods, potentially affecting physical natural gas markets subject to FERC jurisdiction. The Settling Respondents did not admit or deny the allegations but stipulated to specific facts about their positions and trades on key dates.
They acknowledged accountability for trading that appeared atypical and anomalous, potentially eroding public confidence in settlement prices. The settlement was influenced by the diminished financial assets of the Settling Respondents, reducing the likelihood of collecting larger proposed penalties.
It resolves claims against all named parties except Brian Hunter and is coordinated with a related Commodity Futures Trading Commission (CFTC) action. The agreement requires dismissal of a pending appeal challenging FERC's jurisdiction and concedes FERC's subject matter jurisdiction over the matter.
February 24, 2006 Trading Activity: The Settling Respondents stipulated to holding significant positions in the March 2006 NG Futures Contract at the start of the trading day and selling substantial volumes during the settlement period.
March 29, 2006 Trading Activity: Similar to February, the Settling Respondents held positions in the April 2006 NG Futures Contract and conducted sales during the settlement window.
April 26, 2006 Trading Activity: Positions and sales mirrored prior months for the May 2006 NG Futures Contract.
Exceeding Position Limits on February 23, 2006: Amaranth LLC's NG Futures Contract position surpassed NYMEX accountability levels and hedge exemptions.
Exceeding Position Limits on May 23, 2006: A repeat instance where Amaranth LLC held positions beyond NYMEX limits.
The total civil penalty is $7,500,000.
