If an explanation of complex financial products has ever left you feeling more confused than you were before, contact Evan Koster. Evan demystifies the products and their legal implications — in both English and Spanish — and represents clients in a broad spectrum of derivatives, commodities, and structured products in the United States and Latin America.

Evan's experience is both broad — including all asset classes, such as commodities, fixed income, foreign exchange, and equities — and narrow, including energy derivatives (e.g., natural gas, oil, power) and energy trading. In addition to his transactional work, he counsels clients regarding Dodd-Frank derivatives regulatory and compliance issues, and has been active in advocacy related to the Dodd-Frank rulemaking process.

Before joining Hogan Lovells, Evan was an in-house derivatives counsel at two financial institutions and an outside derivative counsel to a number of Fortune 500 companies and sovereign entities. His experience with many clients across the spectrum provides the perspective he needs to help close transactions and solve issues quickly.

Not content with having just one area of specialization, Evan also represents financial institutions, sovereigns, and corporate borrowers in Latin American debt capital markets, especially energy-related transactions, in both primary offerings and liability management exercises such as restructurings. He has represented clients in leading sovereign and quasi-sovereign debt transactions in Latin America, including the Republic of Ecuador's return to the capital markets in 2014.

Evan is frequently quoted in the Economist, Financial Times, Bloomberg, Risk Magazine, and Latin Lawyer, and has written on topics related to derivatives and Latin American debt capital markets transactions. He's been recognized for structured finance and derivatives, as well as project finance, in the Legal 500.
