[1] Includes the volume of contracts for index, equity, commodity future and cash conversion options.

[2] Interest rate swap offsetting the Company's floating rate debt on the Company's term loan. See Note 16.

[3] In accordance with US GAAP, portfolio funds are measured at fair value using the net asset value per share (or its equivalent) as a practical expedient are not classified in the fair value hierarchy. Carried interest and equity method investments presented in the table above are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the consolidated statement of financial condition.

[4] In accordance with the terms of the purchase agreements for acquisitions that closed during the first quarter of 2019 (the acquisition of Quarton International AG "Quarton"), the fourth quarter of 2020 (the acquisition of MHT Partners, LP "MHT") and the fourth quarter of 2021 (the acquisition of Portico Capital Advisors "Portico"), the Company is required to pay to the sellers a portion of future net income and/or revenues of the acquired businesses, if certain targets are achieved through the periods ended through December 31, 2024. For all acquisitions the Company estimated the contingent consideration liabilities using a combination of Monte Carlo and Discounted Cash Flow methods which require the Company to make estimates and assumptions regarding the future cash flows and profits. Changes in these estimates and assumptions could have a significant impact on the amounts recognized. The undiscounted amounts for the Quarton acquisition can range from $12.5 million to $14.9 million. The undiscounted amounts for the MHT acquisition have no minimum or maximum as it is calculated based on revenue. The undiscounted amounts for the Portico acquisition can range from zero to $58.0 million.

[5] Derivatives are reported on a net basis, by counterparty, when a legal right of offset exists under an enforceable netting agreement as well as net of cash collateral received or posted under enforceable credit support agreements. See Note 2f for further information on offsetting of derivative financial instruments.
